Once assembled, the reaction is placed in a thermal cycler, an instrument that subjects the reaction to a series of different temperatures for set amounts of time. This series of temperature and time adjustments is referred to as one cycle of amplification. Each PCR cycle theoretically doubles the amount of targeted sequence (amplicon) in the reaction. Ten cycles theoretically multiply the amplicon by a factor of about one thousand; 20 cycles, by a factor of more than a million in a matter of hours. In the denaturation process, the two intertwined strands of DNA separate from one another, producing the necessary single-stranded DNA template for replication by the thermostable DNA polymerase. Finally, the synthesis of new DNA begins as the reaction temperature is raised to the optimum for the DNA polymerase.If the temperature during the annealing and extension steps are similar, these two steps can be combined into a single step in which both primer annealing and extension take place.Yet numerous instances exist in which amplification of RNA would be preferred. To apply PCR to the study of RNA, the RNA sample must first be converted to cDNA to provide the necessary DNA template for the thermostable polymerase (Figure 1). This process is called reverse transcription (RT), hence the name RT-PCR. Reverse transcriptases have been adapted for use in a variety of in vitro applications including real-time and endpoint RT-PCR, labeled-cDNA probe generation and cDNA library construction. The ideal reverse transcriptase is robust (highly active under a variety of conditions) and converts all primed RNA within a sample to cDNA, regardless of its abundance, length or secondary structure. Genetic engineering and development of proprietary RT-enhancing buffers have led to the commercial availability of new enzymes that offer superior performance over these naturally occurring RTs. Some thermostable DNA polymerases (e.g.

Traditional methods of cloning a DNA sequence into a vector and replicating it in a living cell often require days or weeks of work, but amplification of DNA sequences by PCR requires only hours. While most biochemical analyses, including nucleic acid detection with radioisotopes, require the input of significant amounts of biological material, the PCR process requires very little. Thus, PCR can achieve more sensitive detection and higher levels of amplification of specific sequences in less time than previously used methods. These features make the technique extremely useful, not only in basic research, but also in commercial uses, including genetic identity testing, forensics, industrial quality control and in vitro diagnostics. Basic PCR is commonplace in many molecular biology labs where it is used to amplify DNA fragments and detect DNA or RNA sequences within a cell or environment. However, PCR has evolved far beyond simple amplification and detection, and many extensions of the original PCR method have been described. This chapter provides an overview of different types of PCR methods, applications and optimization.
This decrease in yield can be attributed to the accumulation of truncated products, which are not suitable substrates for additional cycles of amplification. These products appear as smeared, as opposed to discrete, bands on a gel. They devised an approach using a mixture of two thermostable polymerases to synthesize longer PCR products. Presumably, when the nonproofreading DNA polymerase (e.g., Taq DNA polymerase) misincorporates a dNTP, subsequent extension of the newly synthesized DNA either proceeds very slowly or stops completely. The proofreading polymerase (e.g., Pfu DNA polymerase or Tli DNA polymerase) serves to remove the misincorporated nucleotide, allowing the DNA polymerases to continue extension of the new strand. In addition, template quality is crucial. Depurination of the template, which is promoted at elevated temperatures and lower pH, will result in more partial products and decreased overall yield. Additives, such as glycerol and dimethyl sulfoxide (DMSO), also help lower the strand-separation and primer-annealing temperatures, alleviating some of the depurination effects of high temperatures.This optimized enzyme mixture allows efficient amplification of up to 40kb from lambda DNA or 30kb from human genomic DNA. However, a wide variety of applications, such as determining viral load, measuring responses to therapeutic agents and characterizing gene expression, would be improved by quantitative determination of target abundance. Theoretically, this should be easy to achieve, given the exponential nature of PCR, because a linear relationship exists between the number of amplification cycles and the logarithm of the number of molecules. In practice, however, amplification efficiency is decreased because of contaminants (inhibitors), competitive reactions, substrate exhaustion, polymerase inactivation and target reannealing. As the number of cycles increases, the amplification efficiency decreases, eventually resulting in a plateau effect.
, Tth DNA polymerase) possess a reverse transcriptase activity, which can be activated by using manganese instead of magnesium as a cofactor (Myers and Gelfand, 1991). After this initial reverse transcription step to produce the cDNA template, basic PCR is carried out to amplify the target sequence. The efficiency of the first-strand synthesis reaction, which can be related to the RNA quality, also will significantly affect amplification results. At room temperature, PCR primers can anneal to template sequences that are not perfectly complementary. Since thermostable DNA polymerases have activity at these low temperatures (although in most cases the activity is less than 25%) the polymerase can extend misannealed primers. This newly synthesized region then acts as a template for primer extension and synthesis of undesired amplification products.The formation of nonspecific products and primer-dimer can compete for reagent availability with amplification of the desired product. Thus, hot-start PCR can improve the yield of specific PCR products. This omission prevents the polymerase from extending primers until the critical component is added at the higher temperature where primer annealing is more stringent. However, this method is tedious and increases the risk of contamination. A second, less labor-intensive approach involves the reversible inactivation or physical separation of one or more critical components in the reaction. Finally, the DNA polymerase can be maintained in an inactive state through chemical modification (Moretti, T. et al 1998). Activity is restored during initial denaturation, allowing hot-start PCR. While basic PCR works well when smaller fragments are amplified, amplification efficiency (and therefore the yield of amplified fragments) decreases significantly as the amplicon size increases over 5kb.
Specially designed instruments perform both thermal cycling to amplify the target and fluorescence detection to monitor PCR product accumulation. DNA-binding dyes are easy to use but do not differentiate between specific and nonspecific PCR products and are not conducive to multiplex reactions. Fluorescently labeled nucleic acid probes have the advantage that they react with only specific PCR products, but they can be expensive and difficult to design. Some qPCR technologies employ fluorescently labeled PCR primers instead of probes. The dye is simply added to the reaction, and fluorescence is measured at each PCR cycle. Because fluorescence of these dyes increases dramatically in the presence of double-stranded DNA, DNA synthesis can be monitored as an increase in fluorescent signal. However, preliminary work often must be done to ensure that the PCR conditions yield only specific product. In subsequent reactions, specific amplification can verified by a melt curve analysis. The product length and sequence affect melting temperature (Tm), so the melt curve is used to characterize amplicon homogeneity. Nonspecific amplification can be identified by broad peaks in the melt curve or peaks with unexpected Tm values. By distinguishing specific and nonspecific amplification products, the melt curve adds a quality control aspect during routine use.These probes also can be used to detect single nucleotide polymorphisms (Lee et al. 1993; Bernard et al. 1998). There are several general categories of real-time PCR probes, including hydrolysis, hairpin and simple hybridization probes. These probes contain a complementary sequence that allows the probe to anneal to the accumulating PCR product, but probes can differ in the number and location of the fluorescent reporters. During the annealing step, the probe hybridizes to the PCR product generated in previous amplification cycles.
This point must be determined empirically for different reactions because of the numerous factors that can affect amplification efficiency. Because the measurement is taken prior to the reaction plateau, quantitative PCR uses fewer amplification cycles than basic PCR. This can cause problems in detecting the final product because there is less product to detect. One such approach includes a second primer pair that is specific for a “housekeeping” gene (i.e., a gene that has constant expression levels among the samples compared) in the reaction (Gaudette and Crain, 1991; Murphy et al. 1990). Amplification of housekeeping genes verifies that the target nucleic acid and reaction components were of acceptable quality but does not account for differences in amplification efficiencies due to differences in product size or primer annealing efficiency between the internal standard and target being quantified. In competitive PCR, a known amount of a control template is added to the reaction. This template is amplified using the same primer pair as the experimental target molecule but yields a distinguishable product (e.g., different size, restriction digest pattern, etc.). The amounts of control and test product are compared after amplification. While these approaches control for the quality of the target nucleic acid, buffer components and primer annealing efficiencies, they have their own limitations (Siebert and Larrick, 1993; McCulloch et al. 1995), including the fact that many depend on final analysis by electrophoresis.Some of these analyses rely on blotting techniques, which introduce another variable due to nucleic acid transfer efficiencies, while other assays were developed to eliminate the need for gel electrophoresis yet provide the requisite specificity. Real-time PCR, which provides the ability to view the results of each amplification cycle, is a popular way of overcoming the need for analysis by electrophoresis.
The free magnesium changes of 0.6mM observed in their experiments dramatically affected amplification yields in an allele-specific manner. They postulated that magnesium chloride precipitates as a result of multiple freeze-thaw cycles. Amplifications were performed using various Mg concentrations to demonstrate the effect on the amplification of a 1.8kb target luciferase gene. The reaction products were analyzed by agarose gel electrophoresis followed by ethidium bromide staining.The buffer regulates the pH of the reaction, which affects DNA polymerase activity and fidelity. The buffer also contains a compound that increases the density of the sample so that it will sink into the well of the agarose gel, allowing reactions to be directly loaded onto an agarose gel without the need for loading dye. The yellow dye migrates at a rate faster than primers ( 2 at a concentration of 7.5mM for a final concentration of 1.5mM. In most cases, this is an excess of enzyme, and adding more enzyme will not significantly increase product yield.Accurate dispensing of small volumes of enzyme solutions in 50% glycerol is difficult, so we strongly recommend preparing a reaction master mix, which requires a larger volume of each reagent, to reduce pipetting errors. Also, avoid primers with intra- or intermolecular complementary sequences to minimize the production of primer-dimer. Intramolecular regions of secondary structure can interfere with primer annealing to the template and should be avoided. Primers can be designed to include sequences that are useful for downstream applications.Reagents commonly used to purify nucleic acids (salts, guanidine, proteases, organic solvents and SDS) are potent inactivators of DNA polymerases. In some cases, the inhibitor is not introduced into the reaction with the nucleic acid template. A good example of this is an inhibitory substance that can be released from polystyrene or polypropylene upon exposure to ultraviolet light (Pao et al.
1993; Linquist et al. 1998). Failure to amplify the control DNA usually indicates the presence of an inhibitor. Additional steps to clean up the DNA preparation, such as phenol:chloroform extraction or ethanol precipitation, may be necessary. For example, of a 4kb plasmid containing a 1kb target sequence, 25% of the input DNA is the target of interest. Thus, approximately 1,000,000-fold more human genomic DNA is required to maintain the same number of target copies per reaction. Common mistakes include using too much plasmid DNA, too much PCR product or too little genomic DNA as the template. Reactions with too little DNA template will have low yields, while reactions with too much DNA template can be plagued by nonspecific amplification. When reamplifying a PCR product, the concentration of the specific PCR product is often not known. We recommend diluting the previous amplification reaction 1:10 to 1:10,000 before reamplification. The lengths and temperatures for the other steps of a PCR cycle do not usually vary significantly. However in some cases, the denaturation cycle can be shortened or a lower denaturation temperature used to reduce the number of depurination events, which can lead to mutations in the PCR products. Using an annealing temperature slightly higher than the primer Tm will increase annealing stringency and can minimize nonspecific primer annealing and decrease the amount of undesired products synthesized. Using an annealing temperature lower than the primer Tm can result in higher yields, as the primers anneal more efficiently at the lower temperature. In many cases, nonspecific amplification and primer-dimer formation can be reduced through optimization of annealing temperature, but if undesirable PCR products remain a problem, consider incorporating one of the many hot-start PCR methods. The Tm also can be calculated using the Biomath Calculators. Numerous formulas exist to determine the theoretical Tm of nucleic acids (Baldino, Jr. et al.
With this approach, preliminary experiments must be performed prior to the quantitation experiments to show that the signal generated is proportional to the amount of the desired PCR product and that nonspecific amplification does not occur. The hairpin probe is designed so that the probe binds preferentially to the target DNA rather than retains the hairpin structure. As the reaction progresses, increasing amounts of the probe anneal to the accumulating PCR product, and as a result, the fluor and quencher become physically separated. The fluor is no longer quenched, and the level of fluorescence increases. One advantage of this technique is that hairpin probes are less likely to mismatch than hydrolysis probes (Tyagi et al. 1998). However, preliminary experiments must be performed to show that the signal is specific for the desired PCR product and that nonspecific amplification does not occur. In the first approach, the energy emitted by the fluor on one probe is absorbed by a fluor on the second probe, which hybridizes nearby. In the second approach, the emitted energy is absorbed by a second fluor that is incorporated into the PCR product as part of the primer. Both of these approaches result in increased fluorescence of the energy acceptor and decreased fluorescence of the energy donor. The use of hybridization probes can be simplified even further so that only one labeled probe is required. In this approach, quenching of the fluor by deoxyguanosine is used to bring about a change in fluorescence (Crockett and Wittwer, 2001; Kurata et al. 2001). The labeled probe anneals so that the fluor is in close proximity to G residues within the target sequence, and as probe annealing increases, fluorescence decreases due to deoxyguanosine quenching. With this approach, the location of probe is limited because the probe must hybridize so that the fluorescent dye is very near a G residue.
The advantage of simple hybridization probes is their ability to be multiplexed more easily than hydrolysis and hairpin probes through the use of differently colored fluors and probes with different melting temperatures (reviewed in Wittwer et al. 2001). These probes also can be used to detect single nucleotide polymorphisms (Lee et al. 1993; Bernard et al. 1998). There are several general categories of real-time PCR probes, including hydrolysis, hairpin and simple hybridization probes. These probes contain a complementary sequence that allows the probe to anneal to the accumulating PCR product, but probes can differ in the number and location of the fluorescent reporters. GoTaq qPCR Systems contain BRYT Green Dye, which provides maximum amplification efficiency and greater fluorescence than SYBR Green. Many of these suggestions also apply when using other DNA polymerases. Template DNA concentration, chelating agents present in the sample (e.g., EDTA or citrate), dNTP concentration and the presence of proteins all can affect the amount of free magnesium in the reaction. In the absence of adequate free magnesium, Taq DNA polymerase is inactive. Excess free magnesium reduces enzyme fidelity (Eckert and Kunkel, 1990) and may increase the level of nonspecific amplification (Williams, 1989; Ellsworth et al. 1993). For these reasons, researchers should empirically determine the optimal magnesium concentration for each target. The effect of magnesium concentration and the optimal concentration range can vary with the particular DNA polymerase. Before assembling the reactions, be sure to thaw the magnesium solution completely prior to use and vortex the magnesium solution for several seconds before pipetting. Magnesium chloride solutions can form concentration gradients as a result of multiple freeze-thaw cycles, and vortex mixing is required to obtain a uniform solution. These two steps, though seemingly simple, eliminate the cause of many failed experiments.
1989; Rychlik et al. 1990). The formula below can be used to estimate the melting temperature for oligonucleotides: The risk of undesirable PCR products appearing in the reaction increases as the cycle number increases, so we recommend performing only enough cycles to synthesize the desired amount of product. If nonspecific amplification products accumulate before sufficient amounts of PCR product can be synthesized, consider diluting the products of the first reaction and performing a second amplification with the same primers or primers that anneal to sequences within the desired PCR product (nested primers). There are many PCR enhancers, which can act through a number of different mechanisms. These reagents will not enhance all PCRs; the beneficial effects are often template- and primer-specific and will need to be determined empirically. Some of the more common enhancing agents are discussed below. GC-rich templates can be problematic due to inefficient separation of the two DNA strands or the tendency for the complementary, GC-rich primers to form intermolecular secondary structures, which will compete with primer annealing to the template. Betaine reduces the amount of energy required to separate DNA strands (Rees et al. 1993). DMSO and formamide are thought to aid amplification in a similar manner by interfering with hydrogen bond formation between two DNA strands (Geiduschek and Herskovits, 1961). Concentrations of DMSO greater than 10% and formamide greater than 5% can inhibit Taq DNA polymerase and presumably other DNA polymerases as well (Varadaraj and Skinner, 1994). These additives can increase DNA polymerase stability and reduce the loss of reagents through adsorption to tube walls. Ammonium ions can make an amplification reaction more tolerant of nonoptimal conditions.Use separate work areas and pipettors for pre- and post-amplification steps. Use positive displacement pipettes or aerosol-resistant tips to reduce cross-contamination during pipetting.
Wear gloves, and change them often. PCR reagents can be treated with isopsoralen, a photo-activated, cross-linking reagent that intercalates into double-stranded DNA molecules and forms covalent, interstrand crosslinks, to prevent DNA denaturation and replication. These inter-strand crosslinks effectively render contaminating DNA unamplifiable. UNG treatment prevents replication of uracil-containing DNA by causing the DNA polymerase to stall at the resulting abasic sites. For UNG to be an effective safeguard against contamination, the products of previous amplifications must be synthesized in the presence of dUTP. This is easily accomplished by substituting dUTP for some or all of the dTTP in the reaction. Nonproofreading polymerases will readily incorporate dUTP into a PCR product, but proofreading polymerases incorporate dUTP much less efficiently (Slupphaug et al. 1993; Greagg et al. 1999; Lasken et al. 1996). Since dUTP incorporation has no noticeable effect on the intensity of ethidium bromide staining or electrophoretic mobility of the PCR product, reactions can be analyzed by standard agarose gel electrophoresis. While both methods are effective (Rys and Persing, 1993), UNG treatment has the advantage that both single-stranded and double-stranded DNA templates will be rendered unamplifiable (Longo et al. 1990). Many of the important parameters discussed there also apply to RT-PCR. For a discussion of reverse transcriptases commonly used for RT-PCR, see the Thermostable Polymerases and Reverse Transcriptases section (below). Procedures for creating and maintaining a ribonuclease-free (RNase-free) environment to minimize RNA degradation are described in Blumberg, 1987. For optimal results, the RNA template, whether a total RNA preparation, an mRNA population or a synthesized RNA transcript, should be DNA-free to avoid amplification of contaminating DNA.
The most commonly used DNA polymerases for PCR have no reverse transcriptase activity under standard reaction conditions, and thus, amplification products will be generated only if the template contains trace amounts of DNA with similar sequences. The specific 540bp amplicon is indicated.For example, a primer that anneals specifically to the 3?-end of the transcript (a sequence-specific primer or oligo(dT) primer) may be problematic when reverse transcribing the 5?-ends of long mRNAs or molecules that have significant secondary structure, which can cause the reverse transcriptase to stall during cDNA synthesis. Random hexamers prime reverse transcription at multiple points along the transcript. For this reason, they are useful for either long mRNAs or transcripts with significant secondary structure. To differentiate between amplification of cDNA and amplification of contaminating genomic DNA, design primers to anneal to sequences in exons on opposite sides of an intron so that any amplification product derived from genomic DNA will be much larger than the product amplified from the target cDNA. This size difference not only makes it possible to differentiate the two products by gel electrophoresis but also favors the synthesis of the smaller cDNA-derived product (amplification of smaller fragments is often more efficient than that of long fragments). We recommend using a final concentration of 1?M primer (50pmol in a 50?l reaction) as a starting point for optimization. More information on PCR primer design is provided in the PCR Primer Design section. The higher reaction temperature will minimize the effects of RNA secondary structure and encourage full-length cDNA synthesis. It has been reported that AMV reverse transcriptase must be inactivated to obtain high yields of amplification product (Sellner et al. 1992; Chumakov, 1994).
If the target RNA is rare or if only a small amount of starting material is available, it may be necessary to increase the number of cycles to 45 or 50 or dilute the products of the first reaction and reamplify. Thermostable DNA polymerases revolutionized and popularized PCR because of their ability to withstand the high denaturation temperatures. The use of thermostable DNA polymerases also allowed higher annealing temperatures, which improved the stringency of primer annealing. All of the DNA polymerases mentioned below can be used to amplify first-strand cDNA produced by a reverse transcriptase, such as AMV RT, in two-enzyme RT-PCR. These two groups have some important differences. When the amplified product is to be cloned, expressed or used in mutation analysis, Pfu DNA polymerase is a better choice due to its high fidelity. However, for routine PCR, where simple detection of an amplification product is the goal, Taq DNA polymerase is the most commonly used enzyme because yields tend to be higher with a nonproofreading DNA polymerase. The single-nucleotide overhang can simplify the cloning of PCR products. The fidelity is slightly higher at lower pH, lower magnesium concentration and relatively low dNTP concentration (Eckert and Kunkel, 1990; Eckert and Kunkel, 1991). For products larger than approximately 10kb, we recommend an enzyme or enzyme mix and reaction conditions that are designed for long PCR. This enzyme is commonly used in PCR (Gaensslen et al. 1992), where its activity is similar to that of Taq DNA polymerase.For primer extension, RT-PCR and cDNA synthesis using RNA templates with complex secondary structure, the high reaction temperature of Tth DNA polymerase may be an advantage over more commonly used reverse transcriptases, such as AMV and M-MLV reverse transcriptases. Recombinant Tth DNA polymerase has been shown to exhibit RNase H-like activity (Auer et al. 1995).
Pfu DNA polymerase can be used alone to amplify DNA fragments up to 5kb by increasing the extension time to 2 minutes per kilobase. It is also used in blends with DNA polymerases lacking the proofreading function, such as Taq DNA polymerase, to achieve longer amplification products than with Pfu DNA polymerase alone (Barnes, 1994). However, the proofreading activity can shorten PCR primers, leading to decreased yield and increased nonspecific amplification. Reverse transcriptases use an RNA template to synthesize DNA and require a primer for synthesis, like other DNA polymerases. Polymerization from a primer then proceeds as for DNA-dependent DNA polymerases.For these templates, M-MLV RT or M-MLV RT, RNase H minus, may be a better choice. The enzyme also has DNA-dependent DNA polymerase activity at high enzyme levels (Roth et al. 1985). M-MLV RT is used in a variety of applications, including cDNA synthesis, RT-PCR and RACE (Gerard, 1983). However, for short templates with complex secondary structure, AMV RT or M-MLV RT, RNase H minus, may be a better choice due to their higher optimal temperatures. M-MLV RT is less processive than AMV RT, so more units of M-MLV RT may be required to generate the same amount of cDNA (Schaefer, 1995). However, for shorter templates with complex secondary structure, AMV reverse transcriptase may be a better choice because it can be used at higher reaction temperatures. As the names suggest, the deletion mutant had a specific sequence in the RNase H domain deleted, and the point mutant has a point mutation introduced in the RNase H domain. The point mutant is often preferred over the deletion mutant because the point mutant has DNA polymerase activity comparable to that of the wildtype M-MLV enzyme, whereas the deletion mutant has a slightly reduced DNA polymerase activity compared to that of the wildtype enzyme (Figure 4).

advantage fitness manual treadmill
The biggest motivation to choose a manual treadmill is the low cost. However, you can find a quality motorized treadmill for a relatively low cost if you know where to look. Regardless of what you choose remember to have fun and commit yourself to a better, healthier you. Kathryn O'Neill is the chief editor for Treadmill Review For more buying tips, treadmill brand reviews, and best buys visit Elliptical trainers make your weight loss cardio program quiet, low impact, and challenging.Most consumers like to read treadmill reviews before they make a purchase in order to get the best value for their money.These are natural activities for us.Here are some uses (that you should never, ever actually take seriously, of course!) you may not have thought of for your forgotten purchases.For example, a tempo of 3-1-2-0 means to lower the weight for a count of 3, pause for a count of 1, raise the weight for a count of 2, and do not pause before starting the next repetition.If you spend less than that don't expect the machine to be as well built as the higher end models. Your workout will be different depending on your choice. You will have to put more effort into a workout on a manual treadmill, but most motorized treadmills have better features and construction.They rival the best-motorized treadmills in sturdy design as well as in having a high price tag. They have become the darling of athletic trainers and you may see them at your local gym. Compare these categories and see which type of treadmill would work best for your needs.The belt only moves if you move it. Both runners and walkers expend more effort on a curved belt non-motorized treadmill than on a motorized treadmill. This has fitness benefits as users can get their heart rates into a higher zone at a lower speed. One study found that subjects expended 30 percent more energy at the same speed. But the trade-off was that they preferred to run or walk at a slower speed so as to keep their exertion constant. ? ?

The action of your feet against the treadmill moves the belt. With a motorized treadmill you keep pace as the treadmill motor moves the belt for you at a pace you set electronically. They also tend to be smaller, take up less space and are easier to move (since they aren't as heavy as a motorized treadmill). Some people have theorized that manual treadmills burn more calories than motorized treadmill since you supply the power to move the belt. This is unfortunately NOT TRUE. Because you supply the power, unless you are in top athletic shape, you will tend to move slower and get tired more easily. This results in LESS calories burned on a manual treadmill. Plus, the action of getting the belt to move initially and keep it moving can cause a strain on your joints. It's also difficult to run on a manual treadmill so if you want to start a jogging program or train as a runner, a manual treadmill would not meet your needs. However, they tend to last longer and are built to take more of a beating. Also, because the belt moves for you at varying speeds, this motivates you to keep up and actually results in more calories burned (vs.You can easily adjust the speed and incline on most motorized treadmills, usually while still on the machine. This makes it much more convenient and saves the strain on your joints. A final advantage to the motorized treadmills is that they tend to have more options and features (iFit compatibility, numerous built-in workout programs, scrolling information consoles). This makes your workout more interesting and possibly even enjoyable as you can watch your progress. This means that you will probably USE the treadmill more often which again results in more calories burned and a better body achieved. The Final Conclusion: Unless you're in extremely good physical shape, a manual treadmill is not recommended. Choose a motorized treadmill for maximum calorie burning and exercise convenience.
Many users say they must hold onto the handles due to the incline, which ruins good walking and running form and likely reduces calorie burn. A curved-belt manual treadmill does not have this drawback as you can vary the incline by moving your feet farther forward or more towards the middle of the belt. Lack of features: You won't have built-in workouts, apps, and other features. You'll have to use other resources such as apps and online treadmill workout plans to vary your workout. Most have a simple battery-powered display that can show workout details such as elapsed time, distance, calories burned, speed, and a pulse sensor. Less sturdy: Flat-belt manual treadmills, in general, have a less sturdy construction, as you can see from the user weight limits. They also seem to have more flaws such as belt slippage and noise. Check the user weight limit for any model as a way of determining how sturdy it may be. Curved-belt manual treadmills feature more robust construction and higher quality. Walk, don't run: Because of the less sturdy construction, flat-belt manual treadmills are best suited for walking rather than running. They also often have shorter belts, so you can't use a long-running stride. If you want to use a treadmill for running, choose a curved-belt manual treadmill or a better-quality motorized treadmill. In choosing one of these models, look for a user weight capacity of at least 325 pounds as that is the best indication of the quality of construction. Check the warranty and avoid any with a warranty of under one year. You can also check brand quality at sites such as TreadmillDoctor.com, which pulls no punches. Of flat-belt models, the best-reviewed include:Fitness Reality TR3000 Maximum Weight Capacity Manual Treadmill: It has a 325-pound weight capacity and a limited 3-year warranty. The category is new and there are fewer models and manufacturers.
The runners had much higher heart rates at the same speed when on the curved belt treadmill—more than 20 beats per minute higher on average. The runners who were lighter in weight had to work harder to overcome the treadmill belt resistance. ? ?Walkers may be satisfied with a flat-belt or curved-belt model and be able to get a more intense workout at a lower speed. It is likely that you will expend more calories per mile. ? ? You control the speed by putting in more effort rather than trying to keep up with a moving belt. On a curved-belt treadmill, you speed up by placing your feet further forward and slow down by striking closer to the center of the belt. No electricity needed: You can use a manual treadmill anywhere and aren't dependent on placing the treadmill near an electrical outlet. Safety: A non-motorized treadmill stops when you stop ? ?; you don't have to wear a safety cord to stop it if you slip and fall as you should with a motorized treadmill. This also makes it a little safer around children and pets. High-intensity interval workouts: Athletic trainers use curved-belt manual treadmills as part of workouts that alternate high and moderate intensity. Many professional sports teams use these models for training, doing sprint intervals on the curved-belt treadmill. Straining against the belt can stress your joints. If you have knee or hip arthritis, this may be an issue. You may have to raise the incline of a flat-belt manual treadmill significantly to make it easy enough to get the belt moving. Once you do that, you are walking uphill and that may not be what you prefer for your workout. Can only set incline by getting off a flat-belt manual treadmill: Once the belt is moving, you would have to stop and get off to change the incline. You are stuck with one incline level during each workout and often that is quite a steep incline of 10 percent.
It's easier to fall on one if you are distracted or stumble and then get propelled off the back. You need to wear a safety cord to shut it off in case of a fall. Cost: Motorized treadmills for home use start at a higher price point than flat-belt manual treadmills. Models in lower price ranges usually have underpowered motors, are less sturdy, and have fewer options. You will need to read these critically.

By June, you may begin to see close-out sales on models that remain in stock. Be aware that most treadmills sell year-round for far under their manufacturer's suggested retail price, so you should always shop for deals. It can pay to spend time talking to a dealer about how you plan to use the treadmill—walking, running, multiple users, and types of workouts. They can help you decide what features you need.Many people sell lightly-used treadmills after their resolutions wear off or when they need to move. Look for great deals from private sellers in the summer. You may also be able to purchase commercial grade used treadmills from gyms that are updating their machines. Check the reviews of models you are interested in and see how they have held up for purchasers.

Models you can expect to find at a local health club include:It is also the treadmill used in research studies. It also makes the list of top treadmills overall by Runner's World. Speedfit Speedboard: This brand has both a Lite and a ProXL model. TrueForm Runner: This machine is available with a running track surface, rubberized belt, and even a turf surface for football or soccer players. HiTrainer: This company has three models for audiences including fitness, sports conditioning, and rehabilitation. The horsepower of the motor is one of the big factors the quality of the machine. You should look for at least 1.5 continuous horsepower (CHP). You need a bigger motor for heavier users and for higher speeds.Speed and incline adjustment during workout: You can adjust the speed and incline while you are still walking or running on most motorized treadmills. Some models also have a decline feature so you can go downhill, better simulating overground walking and running. More workout features: Motorized treadmills are packing more and more workout features into their consoles?, even at the lower price points. They often will work with apps to provide fun and interesting workouts, and programs to train you for performance at different distances such as 5K, 10K, half marathon, and marathon. Suitable for longer training sessions: You can put in long endurance sessions on a motorized treadmill, while manual treadmills are generally used for shorter workouts. Running and walking: You are able to find models with motor power and treadmill belt length to accommodate runners as well as walkers. As the motor adds weight, these machines are more stable than flat-belt non-motorized treadmills. Safety: A motorized treadmill can be a safety hazard.
In these cases, when someone falls, the belt keeps moving. One major advantage of manual treadmills is that they are, by definition, motorless treadmills. That means that if you trip or stumble, you don’t have to worry about the belt throwing you backward. Of course, manual treadmills aren’t injury-proof. However, they are a statistically safer alternative to electric treadmills. Quieter The absence of that electric motor also means that manual treadmills are much quieter. Manual treadmills do produce a little bit of sound. The quiet resistance mechanisms, moving belt, and pitter-patter of your own footstep do make a little noise. But they aren’t nearly as noisy as electric treadmills. With this newfound peace and quiet, you can more easily watch TV, stream a show, or enjoy some music while on your non-motorized treadmill. More Compact One huge advantage that non-electric treadmills have over their electric counterparts is that they tend to be smaller. Manual treadmills don’t need to fit a bulky motor or big electronic components anywhere. This helps them maintain a much smaller form factor. As a bonus, most manual treadmills are foldable. After your workout, you can simply fold up your compact manual treadmill and slot it in a corner, in a closet, or behind some furniture. Better Workout Electric treadmills are commonly criticized for being ineffective at training for actual running. When you run on the ground, the body mechanics are very different. From the moment your foot strikes the ground outside, you’re using muscles in your foot, leg, and entire body to effectively pull the ground backward and propel yourself forward. With every step you take, you’re using your posterior chain to pull the ground underneath you. On an electric treadmill, your body is making similar movements, but the mechanics are very different. Instead of pulling the ground backward as you propel your body forward, the treadmill feeds the belt underneath you.
You’re essentially moving your feet to bounce on a moving belt. On a manual treadmill, however, the mechanics are closer to running outside. The belt on a non-motorized treadmill isn’t passively fed underneath you. Instead, when you’re running, you’re actively pulling the belt underneath you. This will work your muscle much more similarly to running outside. Manual treadmills more closely mimic the body mechanics of running outside.

Manual Treadmills: 2020 Buyers Guide Manual Treadmills: 2020 Buyers Guide Manual treadmills are a great way to work on cardio while saving money, space, and power. And they do it all at only a fraction of the cost (usually). If you’re in the market for a new treadmill but aren’t sure about the cost, size, or power usage, a manual treadmill may be just what you’re looking for. Unlike the traditional electric version, manual treadmills are non-motorized treadmills that don’t plug into any power source.
Instead, as you stand on the slight incline, your bodyweight makes the belt move. For most motorless treadmills, you simply adjust the tension to change your speed. Electric Why might someone choose a non-motorized treadmill over an electric one. Here are some of the benefits of manual treadmills. More Affordable With fewer expensive components, manual treadmills tend to be cheaper than electric treadmills. Among other factors, the motors that power electric treadmills can really drive up the price. Of course, there are high-end manual treadmills that run for more than you might expect. However, these are typically intended for professional athletes and gyms. The best manual treadmills for most people are quite inexpensive. To further sweeten the deal, think about the electricity you pay for in order to power your electric treadmill. Though it’s not super expensive to use each time (it’s less than a dollar for most people), that power usage can add up over the years. A manual treadmill, on the other hand, uses no electricity. More Environmentally Friendly The fact that self-powered treadmills don’t use electricity also makes them more environmentally friendly than their outlet-tethered counterparts. Manual treadmills don’t have to pull any energy from the grid. As a bonus, non-motorized treadmills also tend to use far fewer nonrenewable resources. On top of being smaller and lighter than electric treadmills, they don’t feature many of the nonrenewable components found in motors and electronics. Safer Thousands of people are injured by electric treadmills each year. Of course, not all of these injuries are horribly serious. It’s not uncommon to hear about someone winding up with some scrapes after a mishap on a treadmill. One of the biggest risks with electric treadmills is that their powerful motors move the belt on their own. While many treadmills feature an emergency stop pin that can be tethered to the runner’s body, many people don’t use them.
This non-motorized treadmill features an LCD display at the front of the handrails. It can manually or automatically cycle through speed, time, distance, steps taken, and estimated calories burned. If you place your hands on the sensors built into the rails, it can also display your heart rate. This manual treadmill’s most unique feature is its tensioned arm workout bars. Each bar features manually-adjustable tension so you can give your arms and legs a workout at the same time. Overall, this is another great manual treadmill for home use. It’s versatile, lightweight, and foldable, and its wheels make it easy to move anywhere in the house. BOTTOM LINE With adjustable-tension arm exercise bars, this manual treadmill is great for a full-body workout.As if it wasn’t already light enough, it also features transportation wheels so you can easily roll it around. Despite the smaller form factor, this compact manual treadmill still offers plenty of support. The 41-inch by 13-inch running area supports up to 250 pounds of bodyweight—more than many other larger manual treadmills. The belt tension can be adjusted to fit your ideal walking or jogging speed, but there’s no way to change it while moving. You have to adjust adjust a few screws in order to change the tension, but the slight inconvenience is a byproduct of the compact manual treadmill form factor. This non-motorized treadmill features an LCD panel that displays speed, distance, time, and estimated calories burned. It also comes with a free water bottle. For anyone looking for a small manual treadmill to maximize space and portability, this is a great option. BOTTOM LINE This foldable, 45-pound option is one of the most compact manual treadmills on the market.It’s one of the sturdiest and most robust non-motorized treadmills on this list. At a maximum load of up to 440 pounds, you’ll be hard-pressed to find anything with similar specs at this price range.
The solid steel dual flywheels can easily be adjusted to 8 different levels of resistance using a convenient lever at waist level. The shock-absorptive deck can also be adjusted between 10 to 14 degrees of incline to further customize your workout intensity. Despite the extra weight, this manual treadmill is surprisingly easy to set up and break down. It features a hydraulic mechanism that helps the deck float softly to the ground to protect your flooring. And transportation wheels on the base make the whole non-electric treadmill easy to move around once folded up. With an incredibly sturdy frame and an impressive amount of support, this manual treadmill is a fantastic pick. Whether you’re an athlete looking for a manual treadmill that can withstand an intense workout or you’re just looking to safely lose some extra weight, you can’t go wrong with Sunny Health and Fitness’ high performance manual treadmill. BOTTOM LINE At a rated maximum load of 440 pounds, this is one of the sturdiest manual treadmills in this price range.The 53 inch by 16 inch deck supports up to 300 pounds of bodyweight, and is designed to withstand the most vigorous workout sessions. One of the key features of this manual treadmill is that its belt resistance can be cranked up higher than most. Using a knob at waist level, the tension can be adjust between 16 different resistance levels. If you’re looking for a challenge, you’ve found it. With a wide selection of grippy, sweat-resistant handles and rails, this manual treadmill has a lot of options for hand placement. You can comfortably support yourself at chest level or grab low to get down into more of a sprinting position. Put that high resistance to the test. A hydraulic mechanism ensures that the deck slowly lowers itself to the ground, protecting your floor. This also makes this motorless treadmill very easy to set up after storage. Overall, this non-motorized treadmill is one of the best manual treadmills for athletes.
BOTTOM LINE For athletes who like intense, heavy workouts, this manual treadmill is a great option.The contour of the body and belt make it so as you step forward, the belt slides backward. As you pick up the pace, so does the belt. You set the speed. People who use the AirRunner say that it feels just like running outside. And it’s just as adaptive. You can go from a slow walk to a full sprint without touching any buttons or dials. The 69 inch by 17 inch belt is rated to last 150,000 miles. The shock-absorptive deck is rated to support up to 350 pounds. And per Assault Fitness, there’s no need to adjust or replace the deck or the belt. An LCD display on the front shows your time, speed, distance, pace, watts generated, and estimated calories burned, all at the same time.In fact, the form factor of this manual treadmill in particular emphasizes a proper front-to-mid foot strike, followed by pulling backward with the foot. Manual treadmills like this one properly work the posterior chain, very similarly to running on the ground. All things considered, this is one of the best manual treadmills you can get. If you have the budget for it, the AirRunner can take your workouts to the next level. BOTTOM LINE For professionals and athletes, the AirRunner is one of the best manual treadmills you can get. 3 Manual Treadmills We DON’T Recommend SpeedFit Speedboard ProXL The SpeedFit Speedboard ProXL is an absolutely fantastic manual treadmill in and of itself. In fact, it’s one of the most popular motorless treadmills for gyms and professional settings. Its build quality, features, and warranty are all fantastic. Here’s the catch: The SpeedFit Speedboard ProXL is almost identical in specs to the Assault Fitness AirRunner, but it has a significantly higher price. To be clear, the SpeedFit Speedboard ProXL is an absolutely fantastic manual treadmill, but if you’re in the market at that price range, it makes more sense to go with the Assault Fitness AirRunner.
Avari Magnetic Treadmill The Avari Magnetic Treadmill is a fairly popular non-motorized treadmill on Amazon, but it’s not a great option. Its reviews are mediocre, indicating by and large that the machine doesn’t feel very sturdy. In addition, for some people, the belt begins to catch and stick over time. At this price range, you may as well go with the Phoenix Easy-Up Manual Treadmill. We’ve featured it above as our best compact manual treadmill pick. It’s sturdier, has great reviews, and happens to be much more popular on Amazon. Artist Hand Folding Manual Treadmill If you’re in the market for a budget manual treadmill, chances are you’ll come across the Artist Hand Manual Treadmill. But at such a low price point, you can’t expect much from a motorless treadmill. Reviews indicate that it’s not very sturdy and the belt isn’t reliable. If you’re looking for a cheap manual treadmill, we would recommend the Phoenix Easy-Up Manual Treadmill again. It’s one of the most inexpensive options that doesn’t skimp out on quality. Summary Manual treadmills are a great way to get some cardio exercise at home. And despite the lower price range, they offer quite a few advantages compared to electric treadmills. Notably, they’re quieter, more environmentally friendly, and can deliver a better workout. Equipped with the information from this buyers guide, you should be able to pick the best manual treadmill for your needs.Electric More Affordable More Environmentally Friendly Safer Quieter More Compact Better Workout Top 6 Best Manual Treadmills Best for Most People Runner-Up Best Small Manual Treadmill Heaviest Maximum Load Best Performance Professional Pick 3 Manual Treadmills We DON’T Recommend Summary.

Popular electric models come with computerized settings, speeds and inclines that can target certain areas of the body, or even certain training regimens, such as strength training and interval training. Though these models have an array of benefits, manual treadmills can be more convenient, as they are easier to store and don't require an electric outlet. They do not offer the varied settings, but do provide a beneficial cardiovascular workout routine at a low price. With a manual treadmill you can avoid weather-related circumstances that may interfere with your workout. You can run, power walk, walk, lunge and side skip on a manual treadmill, just as if you were on an automatic treadmill. You can start by walking, followed by a power walk, followed by a jog and then ending in a sprint. It is important to remember that there is not an emergency button to halt the moving belt, as with most electronic models. If you need to get off suddenly, grab hold of the handles and jump so both feet land on the platforms around the moving belt. The belt will slow down on its own. Some models also fold up so they can fit in a closet or under a bed. Other models have wheels on the front, allowing you to roll the treadmill from room to room without any hassle. Due to not needing electricity, the manual treadmill can even be brought on a porch or patio if you desire to exercise in the fresh air. Use the treadmill with caution as it is possible to lose balance and fall from the moving belt. Remember to stretch before and after using the treadmill to avoid injury.

However, after the server has been running for a while, you should inspect the Database Info page of the Advantage Configuration Utility to ensure that your initial settings are sufficient. If you find that you have to make adjustments to one or more of the settings found on the Configuration pages of the Advantage Configuration Utility, you will need to stop and then restart your server before your changes take effect. Note that the maximum number of connections is not the same as the maximum number of users. Each machine that is currently accessing the server counts as a user. Each user can have multiple connections. You should set Number of Connections to the maximum user count times the maximum number of connections each user requires. This button, when clicked, restores all settings under the Configuration Utility tag.This log file is a free table that you can open using the Advantage Data Architect, or using any other utility capable of viewing ADT or DBF files. (This file was a DBF in Advantage 7.x, but defaults to an ADT table in Advantage 8.) The Advantage technical support team sometimes uses this file to help identify the source of unusual problems that you encounter. These important files permit ADS to either commit or roll back changes if there is a failure somewhere in the system before the transaction is complete. These files, which have the.tps extension, are deleted by ADS when the associated transaction is complete. You should not manually delete or attempt to view these files. The 16-bit versions of Advantage use this file internally to manage each user's connection to the server. The 32-bit versions of Advantage do not create or use a semaphore file.

This may take the form of user names and passwords to identify people authorized to use the database. Economy of scale: Combining all the organization’s operational data into one database, and creating a set of applications that work on this one source of data, can result in cost savings. Increased concurrency: Many DBMSs manage concurrent database access, ensuring that two or more users are allowed to access the same file simultaneously, without interfering with each other, or resulting in loss of information or its integrity. Improved backup and recovery services: modern DBMSs provide facilities to minimize the amount of processing that is lost following a failure. Database designers, database administrators, and end-users must understand this functionality to take full advantage of it. Failure to understand the system can lead to bad design decisions, which can have serious consequences for an organization. Cost of setting up a database: The cost of setting up an electronic database varies significantly, depending on the hardware, software and functionality required. Performance: Typically, a file-based system is written for a specific application, such as invoicing. As a result, performance is generally very good. However, the DBMS is written to be more general, to cater for many applications rather than just one. The effect is that some applications may not run as fast as they used to. Higher impact of a failure: The centralization of resources increases the vulnerability of the system. Since all users and applications rely on the availability of the DBMS, the failure of certain components can bring all operations to a halt. To attend the CDW, register at CDW.ictteachersug.net.

Limitations of Accrual Accounting Most companies use manual or computerized accounting to track expenditures and income. Assets, liabilities, revenue, expenses and equity must be documented and transferred to a general ledger containing the company’s financial details. Such information may be analyzed to help business owners make future financial decisions, using the advantages of either manual or computerized accounting. Time Computerized accounting has the advantage of increased efficiency and time management when compared with manual accounting. Computers may more rapidly perform accounting functions or assessments than manual accounting systems, once data has been entered into the system. Accuracy Computerized accounting has the advantage of higher accuracy when compared with manual accounting, according to the College Accounting Coach. The potential for human error is greater when employees are manually completing accounting procedures. Reliability The advantages of manual or computerized accounting systems may be equal when it comes to reliability. But with modern backup systems and increased functionality, the disadvantage of reliability in computerized accounting may be lessened. Creativity in Analysis Although computerized accounting systems are adept at rapidly computing complex analyses of accounting transactions and reports, the subtlety and focus of an analysis’ conjecture or hypothesis depends on the person operating the system. In this view, manual accounting may have an advantage over computerized accounting systems. Without the nuance and experience of an actual person, computerized accounting systems lose their potential for sophisticated analysis. Additionally, analysis may be hampered or obstructed by software design. Reporting The advantages of computerized accounting include fast, complex reporting. Computerized systems can produce invoices, purchase orders and other documents more quickly.
When we consider the high demand for efficiency and speed, manual data entry some advantages when we think of the impact of manual data input on the overall success of digitizing data to achieve a high level of success. Manual data entry is capable of being more accurate than automated data entry because of the level of care in handling a specific task. The human data entry operator can recognize and fix errors when spotted which may lead to fewer errors than in an automated system. However, the extent of manual data entry is more accurate when the method of operation in place lay more emphasis on data accuracy. For example, when a product detail is being captured manually, it is possible to have high-quality products selected than is possible with automatic data entry. When job creation is the goal of a project, manual data entry provides more benefits to the people and government in jobs creation. With more jobs created through manual data entry services, the better the society. Imagine a situation where manual data entry is used in an environment where high-speed data processing system is installed; it will result in the system becoming slow and with buildup queue that will defeat the whole essence of process automation to increase speed and system efficiency. Therefore, the following are some disadvantages of manual data entry service. When a man faces a tedious job, he is bound to commit errors due to the dynamism of human nature, unlike a machine that follows a set of instruction and never gets tired unless when it breaks down. In data security situation involving going through millions of items to check for data integrity and data validation to ensure high accuracy of data element going into a system, the low-speed nature of manual data input will cause system failure.
Imagine a surveillance system where human is allowed to check every person entering a premise manually, the low speed in reviewing everyone incoming and outgoing people will create high traffic that may shut down the system. Classified information may leak, and sensitive data may develop legs and walk away and thus compromise the entire system. However, you can outsource your entry job to reliable outsource data entry services in India who you can trust to deliver your job without compromising the system they are contracted to build. Some time ago, manual effort was used to track and report this information. Today, electronic database management systems manage this information. Logically related data comprises entities, attributes, and relationships of an organization’s information. Examples of databases include: Phone Address Book, Business Customer Lists, Club Membership Lists, Company’s Employee Database, The library database, Video Library, etc. It provides users with tools used to add, delete, access, modify, and analyze data stored in one location. Examples of DBMS software include: Microsoft Office Access, dBase, SQL Server, Oracle, MySQL, Informix, DB2, Paradox, FoxBase, FileMaker Pro, Lotus Approach, etc. A DBMS typically have the following features. A query language (such as SQL) used to manipulate or extract data. Filter Commands- that display data which satisfy certain conditions. Data validation commands: that ensure the integrity of data entered and stored in the database.Errors created during data entry are minimized Many built-in functions are available to in Electronic databases simplify calculations. Improved security: Database security is the protection of the database from unauthorized users. Without suitable security measures, integration makes the data more vulnerable than file-based systems. However, integration allows the Database administrator to define, and the DBMS to enforce, database security.
Many reports are automatically updated and instantly available. Staffing Neither manual nor computerized accounting systems take the advantage when it comes to staffing. It can be costly to staff qualified accountants to complete manual accounting processes, but it can also be costly to staff accountants familiar with specific computerized accounting software and programming. Cost When it comes to cost comparison, the advantages of manual accounting systems are clear. Computerized systems can cost millions of dollars to purchase, implement and maintain. It may be necessary to purchase updated software with some regularity.

Rush holds a Bachelor of Arts from the University of California, San Diego. A model is an abstraction that represents a table in your database. In Sequelize, it is a class that extends Model. This name does not have to be the same name of the table it represents in the database. Usually, models have singular names (such as User ) while tables have pluralized names (such as Users ), although this is fully configurable. We want our model to be called User, and the table it represents is called Users in the database. After being defined, we can access our model with sequelize.models.User. However, the model name was given ( User ).
This way, Sequelize will infer the table name to be equal to the model name, without any modifications: However, what if the table actually doesn't even exist in the database. What if it exists, but it has different columns, less columns, or any other difference? A model can be synchronized with the database by calling model.sync(options), an asynchronous function (that returns a Promise). With this call, Sequelize will automatically perform an SQL query to the database. Note that this changes only the table in the database, not the model in the JavaScript side. Sequelize acceps a match option as an additional safety check, which receives a RegExp: Instead, synchronization should be done with the advanced concept of Migrations, with the help of the Sequelize CLI. The createdAt field will contain the timestamp representing the moment of creation, and the updatedAt will contain the timestamp of the latest update. This means that direct SQL queries (for example queries performed without Sequelize by any other means) will not cause these fields to be updated automatically. This behavior can be changed by passing a specific defaultValue to the column definition: Sequelize provides a lot of built-in data types. To access a built-in data type, you must import DataTypes: DataTypes.INTEGER.ZEROFILL. DataTypes.INTEGER.UNSIGNED.ZEROFILLSequelize can generate UUIDs automatically for these fields, simply use Sequelize.UUIDV1 or Sequelize.UUIDV4 as the default value: Some examples are below. If you want to check that a value. The unique property can be either a. If you provide the same string for multiple columns, they will form aYou can very easily add custom instance or class level methods. Please, note that if you are using the 32-bit version of SQLWays, so you need to install the 32-bit driver and the 64-bit version of SQLWays requires the 64-bit driver.

Dramatic reductions in the cost of obtaining, processing, and transmitting information are changing the way we do business. Most general managers know that the revolution is under way, and few dispute its importance.No company can escape its effects. Dramatic reductions in the cost of obtaining, processing, and transmitting information are changing the way we do business. As more and more of their time and investment capital is absorbed in information technology and its effects, executives have a growing awareness that the technology can no longer be the exclusive territory of EDP or IS departments. As they see their rivals use information for competitive advantage, these executives recognize the need to become directly involved in the management of the new technology. In the face of rapid change, however, they don’t know how. How will advances in information technology affect competition and the sources of competitive advantage. What strategies should a company pursue to exploit the technology. What are the implications of actions that competitors may already have taken. Of the many opportunities for investment in information technology, which are the most urgent? Today, information technology must be conceived of broadly to encompass the information that businesses create and use as well as a wide spectrum of increasingly convergent and linked technologies that process the information. In addition to computers, then, data recognition equipment, communications technologies, factory automation, and other hardware and services are involved.
We then describe how the new technology changes the nature of competition and how astute companies have exploited this. Finally, we outline a procedure managers can use to assess the role of information technology in their business and to help define investment priorities to turn the technology to their competitive advantage. It is affecting the entire process by which companies create their products. Furthermore, it is reshaping the product itself: the entire package of physical goods, services, and information companies provide to create value for their buyers. We call these “value activities.” The value a company creates is measured by the amount that buyers are willing to pay for a product or service. A business is profitable if the value it creates exceeds the cost of performing the value activities. To gain competitive advantage over its rivals, a company must either perform these activities at a lower cost or perform them in a way that leads to differentiation and a premium price (more value). 2 Primary activities are those involved in the physical creation of the product, its marketing and delivery to buyers, and its support and servicing after sale. Support activities provide the inputs and infrastructure that allow the primary activities to take place. Every activity employs purchased inputs, human resources, and a combination of technologies. Firm infrastructure, including such functions as general management, legal work, and accounting, supports the entire chain. Within each of these generic categories, a company will perform a number of discrete activities, depending on the particular business. Service, for example, frequently includes activities such as installation, repair, adjustment, upgrading, and parts inventory management. Linkages exist when the way in which one activity is performed affects the cost or effectiveness of other activities. Linkages often create trade-offs in performing different activities that should be optimized.
This optimization may require trade-offs. For example, a more costly product design and more expensive raw materials can reduce after-sale service costs. A company must resolve such trade-offs, in accordance with its strategy, to achieve competitive advantage. On-time delivery requires that operations, outbound logistics, and service activities (installation, for example) should function smoothly together. Good coordination allows on-time delivery without the need for costly inventory. Careful management of linkages is often a powerful source of competitive advantage because of the difficulty rivals have in perceiving them and in resolving trade-offs across organizational lines. The value system includes the value chains of suppliers, who provide inputs (such as raw materials, components, and purchased services) to the company’s value chain. The company’s product often passes through its channels’ value chains on its way to the ultimate buyer. Finally, the product becomes a purchased input to the value chains of its buyers, who use it to perform one or more buyer activities. A company can create competitive advantage by optimizing or coordinating these links to the outside. For example, a candy manufacturer may save processing steps by persuading its suppliers to deliver chocolate in liquid form rather than in molded bars. Just-in-time deliveries by the supplier may have the same effect. But the opportunities for savings through coordinating with suppliers and channels go far beyond logistics and order processing. The company, suppliers, and channels can all benefit through better recognition and exploitation of such linkages. A company’s cost position reflects the collective cost of performing all its value activities relative to rivals. Each value activity has cost drivers that determine the potential sources of a cost advantage.

After initial start up, it is a good idea to clean the electrode frequently until a schedule based on need has been developed. Since each application is unique, it is difficult to estimate the required frequency of cleaning. Should a problem occur, refer to the following chart to help identify the problem. If replacement is required, follow the procedures listed in the Warranty and Factory Service portion of this manual. Liability under this policy extends for 24 months from date of installation. Liability is limited to repair or replacement of any failed equipment or part proven defective in material or workmanship upon manufacturer’s examination. Description of Unit MegaTronMT controllers can control single or multiple recirculating water systems, including cooling tower and boiler applications, and may have various features depending on the model number. Multiple timers can be supplied depending upon the model number and each timer will include a relay output. All timers can be programmed to be one of the following types. Pulse Time - Accepts pulses from a make-up water meter (supplied separately). Conduit Conduit units are predrilled at the factory and supplied with conduit knockouts for easy hard wiring to supplied detachable connectors on the relay card(s) located in the lower section of the controller. JP4 and JP5 on the board must be jumpered for isolated with an external power source supplied to the external VDC input. The external power source must not exceed 24 volts DC. The location should be convenient to grounded electrical connections, the needed sample line plumbing, and should be on a stable vertical surface. WARNING: Avoid locations that expose the controller to direct sunlight, vapors, vibration, liquid spills or extreme temperatures;. For a successful installation, it is critical to observe the recommended distances and pipe sizes provided in the installation drawings.

Method 1 Continuous - Used when the probe will see a continuous water sample at all times (cooling towers or very large boilers). Controller will continuously monitor the water and control accordingly. 38 Setpoints Menu - Sampling Modes Method 2 Timed - Used only when intermittent sampling is desired (small to medium sized boilers). Controller will control the boiler water conductivity only after an active sample cycle (duration) and then remain inactive during the off-period (interval). Time initiates the control cycle, but the conductivity reading ends it.

No overheating possibility CSA approved Simply unlock the cap with a key, remove the cap and lift the red handle. The clamp is now loose and the gate can be pushed open manually. If the mechanical manual release is unauthorized, the gate tamper can trigger a security system. This is a high-security feature not found in any other gate operator.For this reason the Megatron FAST PRO is outfitted with Maximum Controls’ clamping technology constructed with robust cast iron. This prevents damage to the operator while preserving limit switch locations.The rugged cast iron housing, bronze gears, and double sealed heat-treated solid shafts have been designed by a team with over 40 years of experience in the gearbox industry. That’s over 50 samples per degree of gate travel. Using this positional feedback, intelligent ramp-up and ramp-down of the gate speed is employed to minimize stress on all mechanical components. We combine this technology with a dynamic magnetic brake system which stops the gate instantly when colliding with an obstacle.

advantage database server manual
However, after the server has been running for a while, you should inspect the Database Info page of the Advantage Configuration Utility to ensure that your initial settings are sufficient. If you find that you have to make adjustments to one or more of the settings found on the Configuration pages of the Advantage Configuration Utility, you will need to stop and then restart your server before your changes take effect. Note that the maximum number of connections is not the same as the maximum number of users. Each machine that is currently accessing the server counts as a user. Each user can have multiple connections. You should set Number of Connections to the maximum user count times the maximum number of connections each user requires. This button, when clicked, restores all settings under the Configuration Utility tag.This log file is a free table that you can open using the Advantage Data Architect, or using any other utility capable of viewing ADT or DBF files. (This file was a DBF in Advantage 7.x, but defaults to an ADT table in Advantage 8.) The Advantage technical support team sometimes uses this file to help identify the source of unusual problems that you encounter. These important files permit ADS to either commit or roll back changes if there is a failure somewhere in the system before the transaction is complete. These files, which have the.tps extension, are deleted by ADS when the associated transaction is complete. You should not manually delete or attempt to view these files. The 16-bit versions of Advantage use this file internally to manage each user's connection to the server. The 32-bit versions of Advantage do not create or use a semaphore file. The Communications page of the Advantage Configuration Utility is shown in Figure 1-5. If you want to use a port other than 6262, set LAN Port to a port that is available for both UDP and TCP.

All rights reserved. It permits you to view statistics about your server's operation, and it also permits you to manually set many of the server's configurable properties.For these installations, refer to the documentation for information on configuring Advantage. The Management Utility contains information similar to the Advantage Configuration Utility described in this section. See the Advantage documentation for additional information on the Advantage Database Server Management Utility. This section is not designed to provide a detailed description of how these settings are used. For that information, please refer to the Advantage documentation. The Advantage Configuration Utility shown in Figure 1-1 is displayed. There are three main tabs: Database Info, Installation Info, and Configuration Utility. These pages are described in the following sections. The Current column on the Database Info page displays current usage statistics, while the Max Used column shows the highest value for each statistic since the server was started. For example, if you find that the maximum number of configured connections was used, and that some connections were rejected, you can use the Configuration Utility pages to increase the number of available connections. The Configuration Utility pages are described later in this section. If you need to change these values, you can either reinstall your server or use a special utility that ships with Advantage. This utility, called AdsStamp.exe, permits you to install a new license key and to change your character sets and a few other settings. AdsStamp is described briefly later in this chapter. For information about these options, see the Advantage documentation. You display these additional pages by clicking on the Configuration Utility tab of the Advantage Configuration Utility.

Amazon Customer 5.0 out of 5 stars This book really delivered for me. The authors seem to have a real passion for ADS and, like most things in life, this results in a high-quality product. There is concise but informative stuff about general database structure that quickly progresses on to ADS-specific structure and great ADO.NET information. I learned more about real life ADO.NET from this book than I did from trudging through Visual Studio's help. It's one of those books that just left me feeling extremely good about my decision to buy.It's a rather interesting database in that it uses an ISAM (Indexed Sequential Access Method) structure rather than the now more traditional SQL structure. In my opinion it is a system suitable for applications that have outgrown Microsoft Access, but which do not need the full power (and complexity) of the big databases such as Oracle, DB2 or SQL Server. This book is written by two ADS pros that have an almost missionary zeal in promoting ADS. Still they have done a pretty good job of describing the various ways of getting data into and out of ADS. This includes the ADS GUI, using QBuilder (like the MS Access QBE), and of course writing in SQL itself. The ADS SQL is more advanced than the Jet engine in Access incorporating things like logic that are not supported in Jet.
This port must also be opened in any firewalls separating the server and the applications that need to access it. Leaving Internet Port set to the default of 0 disables Internet access. Depending on the data access mechanism or the specifics of your connection, each client machine may also require an ADS configuration file that contains additional information about the connection.For security purposes, you can also prohibit connections that do not use data dictionaries.

The ADS documentation can also be downloaded in PDF format from All OS (operating system) versions of ADS have an Advantage Database Server Management Utility available from within the Advantage Data Architect. (A stand-alone version of this utility is also available with ADS 7.0 and later.) The Management Utility contains information similar to the Advantage Configuration Utility described in this section. See the ADS documentation for additional information on the Advantage Database Server Management Utility. Note The purpose of the following descriptions is to show you where you can get information about the server. This section is not designed to provide a detailed description of how these settings are used. For that information, please refer to the ADS documentation. The Advantage Configuration Utility shown in Figure 1-1 is displayed. There are three main tabs: Database Info, Installation Info, and Configuration Utility. These pages are described in the following sections. Figure 1-1: Use the Advantage Configuration Utility to view statistics for and to configure your ADS server. Database Info Page The Database Info page, shown in Figure 1-1, contains basic statistics about attached users, connections, work areas, as well as open tables and indexes. The Current column on the Database Info page displays current usage statistics, while the Max Used column shows the highest value for each statistic since the server was started. This information can help you determine whether you need to make adjustments to any of the configurable parameters of the server. For example, if you find that the maximum number of configured connections were used, and that some connections were rejected, you can use the Configuration Utility pages to increase the number of available connections. The Configuration Utility pages are described later in this section.
Finally there is a section on using ADS with various languages such as PHP, Delphi,.NET and more. All in all, this is a complete and well written book on ADS that gives a good introduction to ADS.This book covers everything in great detail- with some very detailed examples. An e-book version of this book is available Please email us if you find technical errors We Other product and company names mentioned. You can also use the data access API to connect to the database and select the required data in code. For information on data providers, refer to the Data Sources article. To locate the database, click the ellipsis button next to the Database field. You can select from the Local, Remote and Internet types. Subsequently, the text of the generated query returns to the Data Source wizard. Create the AdvantageConnectionParameters class object and specify the following properties. Then, assign the connection string name to the SqlDataSource.ConnectionName property. You can do this in the following ways. Imports DevExpress.DataAccess.ConnectionParameters. Imports DevExpress.DataAccess.SqlAny other suggestions. Tell us here. You will also use several support tools to configure your database server, as well as to create your actual databases. Among these are the Advantage Configuration Utility, the Advantage Data Architect, and the Advantage ANSI Collation Utility. Each of these tools is described in the following sections. This utility provides you with several important capabilities. It permits you to view statistics about your server’s operation, and it also permits you to manually set many of the server’s configurable properties. For these installations, refer to the documentation for information on configuring ADS. ON THE CD The ADS documentation is located on this book’s CD-ROM.
Depending on the data access mechanism or the specifics of your connection, each client machine may also require an ADS configuration file that contains additional information about the connection. For information on setting up client applications to connect over the Internet, see the topic “Advantage Internet Server” in the ADS documentation. The Misc. Settings Page Use the final page of the Advantage Configuration Utility, Misc. Settings, shown in Figure 1-6, to set the maximum number of worker threads, as well as the maximum size of the error log. Figure 1-6: The Misc. Settings page of the Advantage Configuration Utility Advantage Data Architect The Advantage Data Architect, whose main screen is shown in Figure 1-7, is a graphical tool that simplifies the creation and configuration of your tables and databases. The Advantage Data Architect is also referred to as ARC. The Advantage Data Architect also includes a wide variety of support features, including the ability to import and export data, execute ad hoc queries, perform checks on your development environment, and much, much more. As a developer, you are likely to use the Advantage Data Architect more than any other tool that ships with ADS. Figure 1-7: The main screen of the Advantage Data Architect While the Advantage Data Architect makes it easy to design your tables and data dictionaries, there are alternatives. Specifically, all of the database-related configuration capabilities provided by Advantage Data Architect can also be performed using Advantage SQL, as well as by programming directly to the ADS API using ACE (the Advantage Client Engine). The Advantage Data Architect provides another benefit, albeit one that is not immediately obvious. It can provide you with insight on how to create and manage your tables and data dictionaries programmatically.
The Advantage Data Architect was written in the Delphi language, and the source code for this Delphi project is available on the CD-ROM that accompanies this book. The Delphi language is easy to read, so even if you are not a Delphi developer, you can probably figure out how specific operations were performed. Because the Advantage Data Architect is such a valuable tool for working with tables and data dictionaries, a large portion of this book discusses its use. In other words, there is no chapter that specifically discusses the Advantage Data Architect. Instead, almost all examples in this book where tables and data dictionaries are manipulated use the Advantage Data Architect. Advantage ANSI Collation Utility ADS ships with the Advantage ANSI Collation Utility, shown in Figure 1-8, a tool that permits you to create custom ANSI collations. The ANSI (American National Standards Institute) character set is a standard mapping of characters to numeric values. These characters include printable characters and special control characters, such as tabs and carriage returns. An ANSI collation sequence defines the order, or precedence, of characters for the purpose of making string comparisons. Figure 1-8: The ANSI Collation Utility Few developers will ever need to use the Advantage ANSI Collation Utility. For most applications that use the English language, you will install one of the provided English collation sequences. Similarly, for most non-English applications, Extended Systems provides localized character sets that ensure proper string comparisons. When installing ADS or ALS, you will choose either a localized character set or an ANSI collation sequence. Which options you have depends on the version of the Advantage Database Server that you are installing. For example, if you are installing the domestic version of ADS, you will be able to select only between an American English collation, a Canadian English collation, and a French Canadian collation.
The Installation Info Page The Installation Info page, shown in Figure 1-2, contains information about the installed server, including the licensed number of users, your serial number, and the server version you are running. Figure 1-2: The Installation Info page of the Advantage Configuration Utility The values on the Installation Info page are not configurable. If you need to change these values, you can either reinstall your server, or use a special utility that ships with ADS. This utility, called adsstamp.exe, permits you to install a new license key and to change your character sets and a few other settings. For information on using adsstamp.exe, refer to the ADS help. For information about these options, see the Advantage Database Server documentation on this book’s CD-ROM. The remaining pages of the Advantage Configuration Utility are used to set the parameters used by the server. You display these additional pages by clicking on the Configuration Utility tab of the Advantage Configuration Utility. In most cases, once you have adjusted the settings of the Advantage Database Server, you will not need to make further changes. However, after the server has been running for a while, you should inspect the Database Info page of the Advantage Configuration Utility to ensure that your initial settings are sufficient. If you find that you have to make adjustments to one or more of the settings found on the Configuration pages of the Advantage Configuration Utility, you will need to stop and then restart your server before your changes take effect. The Database Settings Page Use the Database Settings page, shown in Figure 1-3, to adjust the maximum permitted connections, work areas, and simultaneously opened tables and indexes. Note that the maximum number of connections is not the same as the maximum number of users. Each machine that is currently accessing the server counts as a user. Each user can have multiple connections.
You should set Number of Connections to the maximum user count times the average number of connections each user requires. Figure 1-3: The Database Settings page of the Advantage Configuration Utility The File Locations Page Use the File Locations page, shown in Figure 1-4, to change the location of the error and transaction log files, as well as the semaphore connection file path. This log file is a simple DBF file that you can open as a free table using the Advantage Data Architect, or using any other utility capable of viewing DBF files. Transaction log files are files that the ADS TPS (transaction processing system) creates while updates to a database are being performed within the context of a transaction. These important files permit ADS to either commit or roll back changes if there is a failure somewhere in the system before the transaction is complete. These files, which have the.tps extension, are deleted by ADS when the associated transaction is complete. You should not manually delete or attempt to view these files. The Communications Page If you want to permit applications to connect to your server over the Internet, use the Communications page to define how this communication will be permitted. The Communications page of the Advantage Configuration Utility is shown in Figure 1-5. Figure 1-5: The Communications page of the Advantage Configuration Utility IP Port permits you to set the UDP and TCP ports on which the server will listen for client connections. (“IP,” “UDP,” and “TCP” stand for Internet protocol, universal datagram protocol, and transmission control protocol, respectively.) If IP Port is set to the default 0, it will try to use UDP and TCP port 6262. Leaving Internet Port set to the default of 0 disables Internet access. Note To enable Internet access to the Advantage Database Server, you must also configure the data dictionary used to access the data to accept Internet connections.
Regardless of which character set or collation sequence you install, keep one very important issue in mind. The server, and all client applications that use it, must use the same character set or collation sequence. Doing so ensures that both clients and server agree on how strings are compared. Because both client and server must use the same character set or ANSI collation sequence, it is particularly important for non-English applications to use the ANSI character set provided by Extended Systems, instead of choosing “default on machine.” This is especially important for Advantage Local Server users. Each version of Windows (95, 98, NT, 2000, and so on) has different “default on machine” ANSI collation sequences, even when the same language is configured. Consequently, if one ALS client is using Windows 98 and another is using Windows 2000, collation mismatch errors will result. Caution If you change the character set or collation sequence being used by your clients and server, you must rebuild all indexes before you access any of your tables.

The ADS remote server can be useful even in smaller networks - faster access is one of this version's benefits. The server-based transaction processing also prevents database corruptions (for example, “crashing” or network interruptions). In order to do this you have to have the license key (serial) and the validation code. You can obtain this data from PC CADDIE support after placing the order.
You can automatically load the ADS version recommended by PC CADDIE via the menu ADS Server configuration.This may be necessary, for example, if the ADS server is no longer accessible. In this case, you could no longer work with PC CADDIE. However, if you change the setting to ADS Local Server, you can continue to work on 5 workstations.Newer versions require new licenses.Click Yes on the following window to complete the installation.PC CADDIE automatically makes the necessary settings, which must be changed only in exceptional cases - please contact your system administrator or the PC CADDIE support team in such situations.This is necessary because the local PC CADDIE will start from there, and this is also the location where a few database driver (ADS) functions will be executed - so you have to avoid the situation where the location is not found because the SYSTEM account does not detect user-related drives.
