Cumulative overall

From equation (2), it is possible to derive expressions for the differential and cumulative overall composition distributions (10). 

First, Cd-Cl complexing is described in terms of the cumulative (overall) constant expressions. These are ... 

The stability of a complex is usually described by its stability constant, which is also known as its formation or association constant. The stability constant may refer to a stepwise or a cumulative (overall) complex-formation reaction. If ATassoc applies to the simple reaction... 

Resting cells of a recombinant K. pneumoniae J2B strain that overexpresses an aldehyde dehydrogenase (KGSADH) were utilized for coproduction of 3-HP and 1,3-pro-panediol (PDO) from glycerol. The fed-batch bioconversion was performed under anaerobic conditions in a 1.5 L bioreactor with l.Og CDW/L at a constant pH of 7.0 and resulted in 125.6mM 3-HP and 209.5 mM PDO after 12 h with a cumulative overall productivity, yield, and maximum specific production rate of 27.9mmol/Lh, 0.71 (mol/mol), and 128.5mmol/g CDW/h, respectively.The major by-products were lactate, succinate, and 2,3-butanediol. °... 

In most of these instances the overall reduction in heat flowmay be small, but the cumulative effect within a system maybe enough to reduce the evaporating temperature by as much as 2 K, resulting in a loss in COP of some 6%. 

To determine the overall rate of clearance of administered as TCDD from the body, the total cumulative amount of excreted in feces, urine, and expired air at the end of each day was subtracted from the total dose administered to the animal. These values, representing the percentage of the total dose remaining in the animal at the end of each day, were then plotted semilogarithmically as a function of time... 

Table 14 can be regarded as providing a reasonable overall picture, even if the results cannot applied to any particular case. However, if the underlying principle is accepted, it becomes clear that improvements in a single stage, for example the reduction of instrument variation, has a negligible beneficial effect (if this variation was not outside the normal range ). Even if the contribution of repeatability is re-duced to zero, the cumulative uncertainty is reduced by 10% only, i.e. from 2.2 to y(0.0)2 (0.8)2 (1.0)2 + (1.5)2 = 2.0. This statistical view of errors should help to avoid some unnecessary efforts to improve, e.g., calibration. Additionally, this broad view on all sources of error may help to detect the most important ones. Consequently, without participation in proficiency tests, any method validation will remain incomplete. 

Each value listed in Tables 8.12 and 8.13 is the logarithm of the overall formation constant for the cumulative binding of a ligand L to the central metal cation M, viz. ... 

But the overall dispersion force strength also depends on the total number of electrons in the atom or molecule. It is a cumulative effect. Butane contains 14 atoms and 58 electrons, whereas octane has 26 atoms and 114 electrons. The greater number of electrons increases the total number of interactions possible and, since both melting... 

In many types of processes such as batch constant-pressure filtration or fixed-bed ion exchange, the production rate decreases as a function of time. At some optimal time /opt, production is terminated (at P°pt) and the equipment is cleaned. Figure E4.12a illustrates the cumulative throughput P(t) as a function of time t for such a process. For one cycle of production and cleaning, the overall production rate is... 

At this point, the student reviewed the check clearing process in detail. Checks are issued to a supplier and an encumbrance is placed on an internal account in the chemical company the supplier cashes the check at the supplier s bank the check proceeds through a series of intermediate banks until it arrives at the chemical company s bank the issued amount is removed from the chemical company s bank account (cleared) and the check is then returned to the chemical company where the encumbrance on the internal account is removed. The system must achieve an overall mass balance such that the total or cumulative amount of money issued must eventually equal the total or cumulative amount of money cleared. 

Fig. 15.1 Cumulative attrition rates in the drug discovery process milestones. Decreasing the attrition rate for any of these milestones has significant potential impact for improving the overall efficacy of launching drugs to market.

Bauer et al. describe the use of a noncontact probe coupled by fiber optics to an FT-Raman system to measure the percentage of dry extractibles and styrene monomer in a styrene/butadiene latex emulsion polymerization reaction using PLS models [201]. Elizalde et al. have examined the use of Raman spectroscopy to monitor the emulsion polymerization of n-butyl acrylate with methyl methacrylate under starved, or low monomer [202], and with high soUds-content [203] conditions. In both cases, models could be built to predict multiple properties, including solids content, residual monomer, and cumulative copolymer composition. Another study compared reaction calorimetry and Raman spectroscopy for monitoring n-butyl acrylate/methyl methacrylate and for vinyl acetate/butyl acrylate, under conditions of normal and instantaneous conversion [204], Both techniques performed well for normal conversion conditions and for overall conversion estimate, but Raman spectroscopy was better at estimating free monomer concentration and instantaneous conversion rate. However, the authors also point out that in certain situations, alternative techniques such as calorimetry can be cheaper, faster, and often easier to maintain accurate models for than Raman spectroscopy, hi a subsequent article, Elizalde et al. found that updating calibration models after...
