The first term in Equation (6.8) is basically equal to Equation (3) in Table 6.1, and thereby corresponds to the formation rate of sulfide. However, the areal sulfide formation rate is normally found to be lower in a gravity sewer than in a pressure main, probably because of the effects of the daily changing water level and flow conditions. The value of M is therefore typically lower than shown in Equation (3). Pomeroy and Parkhurst propose M =0.3210-3 m h-1. 

While the volume of concentrate can be determined based on plant capacity and recovery, the evaporation rate at any given site varies with climate. To determine the evaporation rate of fresh water at certain locations, a standard pan evaporation measurement is taken. Evaporation pans are small, open air pans filled with water from which losses in water due to evaporation are measured. Standard size Class A evaporation pans are most commonly used, which are 1.207 m in diameter and 0.25 m in depth. The daily change in depth, minus any rainfall, is used to determine the evaporation rate in mm/day. This rate takes into account the effects of climate on evaporation rate, but corrections for pond area and salinity must be made when determining the evaporation rate of a specific evaporation pond. 

When a number has no zeros after the decimal point, final zeros before the decimal point may or may not be significant, depending upon the usage. If we say that there are 1000 students enrolled in a school, all the zeros probably are significant. But if the population of a city is given as 360,000, the last two or three zeros are not significant, because daily changes make the population uncertain by perhaps several hundred persons. The final zeros in this case are used only to indicate the position of the decimal point. A convenient way to indicate reliability of a number that has final zeros before the decimal point is to... 

The 0.1M K2Ni(CN)4 soln is prepd by titrating 1 mole KCN dissolved in ca 500ml of w contg ammonia, with 0.1M NiS04 soln until murexide indicator(satd soln of Amm purpurate, made fresh daily) changes from yel to purple. Then the soln is diluted to 1 liter...

Assuming a dependency on interfering parameters, it is important to investigate the extent of their influence in order to prove the overall feasibility of the concept, because cross sensitivities and artifacts can cover or spoil the response toward increased oil content. This can certainly happen in the shortterm, but also on long-term-basis, for example because ambient air underlies both daily changes as well as seasonal ones. The sensor response can also be influenced by the aging of the oil in the compressor, which also represents a real life effect. 

Figure 3 Daily changes of REM sleep and corresponding changes of wakefulness during 6 days of RSD by clomipramine (CLI) and 3 days of recovery. During CLI treatment, a larger REM sleep reduction corresponds to a smaller portion of waking changes across treatment and posttreatment days. (From Ref. 9).

One of the models in the process of transpiration can be written as wST = Ys 2Aa + b, where Ys is the return of water a is the rate at which ground water rises (cm/hr) and b is the average daily change in ground water level (cm). 

We have already indicated certain daily changes that take place in the soil-plant-atmosphere continuum. For example, the soil temperature changes, which affects CO2 evolution by respiration in soil microorganisms and in... 

Figure 9-22. Schematic representation of daily changes in the water potentials in the soil, a root, and a leaf of a plant in an initially wet soil that dries over a 1-week period for a rapidly draining sandy soil. TS011 is the water potential in the bulk soil, proot is that in the root xylem, and 4/leaf is the value in a mesophyll cell. Shaded regions indicate night.

Amino acids are the most abundant of the other nutrients present in nectar. The relative proportions of amino acids versus sugars, and the acidity of nectar can change during the day. This may influence the timing of flower visits by specific nectar-seeking visitors, but the significance of these daily changes is not fully understood. 

C. The Incremental backup is best suited for this situation because an Incremental only backs up the daily changed information. A Full backup every day would be impractical, because it would take too long and use several tapes. A Differential backup would use even more tapes. Given these situations, an Incremental backup would be the best choice.
