Again, irrespective of the hardware the chemistry is consistent. The partially regenerated fiber from the spinning machine is contaminated with sulfuric acid, 2inc sulfate, sodium sulfate, carbon disulfide, and the numerous incompletely decomposed by-products of the xanthation reactions. The washing and drying systems must yield a pure cellulose fiber, suitably lubricated for the end use, and dried to a moisture level of around 10%. [Pg.348]

Available Chlorine Test. The chlorine germicidal equivalent concentration test is a practical-type test. It is called a capacity test. Under practical conditions of use, a container of disinfectant might receive many soiled, contaminated instniments or other items to be disinfected. Eventually, the capacity of the disinfectant to serve its function would be overloaded due to reaction with the accumulated organic matter and organisms. The chlorine germicidal equivalent concentration test compares the load of a culture of bacteria that a concentration of a disinfectant will absorb and still kill bacteria, as compared to standard concentrations of sodium hypochlorite tested similarly. In the test, 10 successive additions of the test culture are added to each of 3 concentrations of the hypochlorite. One min after each addition a sample is transferred to the subculture medium and the next addition is made 1.5 min after the previous one. The disinfectant is then evaluated in a manner similar to the phenol coefficient test. For equivalence, the disinfectant must yield the same number of negative tubes as one of the chlorine standards. [Pg.139]

Obviously, any relationship for the composite modulus, E, must yield E = E forV = 1 andE = Ed forVd = 1. [Pg.138]

In the absence of any approximations, Eqs. (9), (10), and (13) must yield the same thermodynamic functions. However, if approximate expressions for the RDF are used, these various equations may yield different thermodynamic functions. [Pg.139]

An overall economic evaluation must be made to ensure that the contemplated project for petroleum development will recover sufficient capital to pay for the total cost of development, installation and assembly effort of the company. Further, the capital return must yield a financial return consistent with the overall company risk involved. Thus, it is very important that the petroleum engineer designing a recovery system understand the company s evaluation criteria that will be used by management in judging whether a new project is to go forward. Chapter 7 (Petroleum Economics) has detailed discussions of general engineering economics and product (or project) evaluation criteria. [Pg.379]

In other instances, it is sufficient for the plant engineer to have a less accurate measurement of what is going on. As well as being technically suitable for the purpose, the instrument chosen will reflect these considerations. In the case of process control, the instrumentation must be reliable and it must yield information, often over very long periods of time, which represents the state of the plant or the process and its history. It is on the basis of this information that the plant engineer will make decisions, many of which will affect the economic viability of the process and some of which will have a direct impact on the safe operation of the plant. [Pg.232]

Propagation step (Section 5.3) The step or series of steps in a radical chain reaction that carry on the chain. The propagation steps must yield both product and a reactive intermediate. [Pg.1248]

It follows that all irreversible processes must yield less than the maximum amount of available energy, or that all irreversible processes are attended by dissipation of energy. [Pg.67]

By similar reasoning, one can show that differential expressions for which equation (Al.18) is true must yield integrals between two fixed states whose values depend upon the path. Such differential expressions cannot be associated with state functions because of the dependence upon path. Therefore, equations (Al.17) and (Al.18) distinguish between differentials that can ultimately be associated with state functions and that cannot. Expressions for which equation (Al.17) is true are called exact differentials while those for which equation (Al.18) is true are called inexact differentials. [Pg.604]

Adding up the steps in a mechanism must yield the net chemical reaction rapid reactions may follow the rate-controlling step. [Pg.131]

The positive charge should reside on a complex entity, and there is no ready means for assessing the products of the neutralization process. Although we know that neutralization must yield 3.8 intermediates/100 e.v., there is no chemical evidence for their contribution to the product distribution. This cannot be interpreted by neutralization yielding predominantly hydrogen atoms, ethyl radicals, or methyl radicals. One can quantitatively account for these intermediates on the basis of the distribution of primary species and second- and third-order ion-molecule reactions (36). [Pg.267]

Content uniformity Nine out of 10 randomly picked and individually analyzed tablets must yield drug contents between 85 and 115% of label claim all 10 results must be within 75-125% of label claim. [Pg.291]

In the concentration step the anodic oxidation must yield between the electrode material (generally Hg) and the analyte anion an insoluble compound... [Pg.201]

The function W(x) is that of Gauss, which was discussed in Section 3.4.5. It is presented in Fig. 3-4, although the normalization condition is in this case somewhat different. As W x) dr represents a probability, its integration over all of the sample space must yield the certainty. The function is thus normalized in the sense that... [Pg.169]

It must yield a rate expression that is consistent with the kinetics observed experimentally. [Pg.80]

The combination of any two members of a group must yield another member of the group (closure). [Pg.148]

By Hess s Law, these two approaches must yield the same energy of interaction between the two double bonds. The virtue of this latter approach is that enthalpy of formation data for the... [Pg.104]

H) The molecular mixing model must yield the correct joint scalar dissipation rate. [Pg.281]

In that case a plot of log (a/ x g)/0-x) versus x2 or of log agx,s/x versus (1-x)2 must yield straight lines with the same slope, from which W can be calculated. [Pg.531]

Two liquids in contact must yield an interface temperature which exceeds the homogeneous nucleation temperature of the cold liquid. The bulk temperature of the cold liquid may be saturated or subcooled. [Pg.198]

One deduces the space group from the symmetry in the crystal s diffraction pattern and the systematic absence of specific reflections in that pattern. The crystal s cell dimensions are derived from the diffraction pattern for the crystal collected on X-ray film or measured with a diffractometer. An estimation of Z (the number of molecules per unit cell) can be carried out using a method called Vm proposed by Matthews. For most protein crystals the ratio of the unit cell volume and the molecular weight is a value around 2.15 AVOa. Calculation of Z by this method must yield a number of molecules per unit cell that is in agreement with the decided-upon space group. [Pg.88]

Equations (5.34) and (5.47) have the same dependence on the concentration variables. The only difference is that for the interfacial reaction the apparent rate constants are directly proportional to the ratio S = QN. This dependency can be experimentally verified by measuring the apparent rate of extraction as a function of the interfacial area and the volume of the phases. A plot of the apparent rate constant of the forward rate of extraction vs. S must yield a straight line through the origin of the axes when case 2 holds. [Pg.237]

It can be seen that addition of cyanide creates a new chiral centre, whereas addition of hydride does not. Therefore, cyanide reacts to give two epimeric products. We already have chirality in the rest of the digitoxose chain, so the cyanide reaction must yield two diastereoisomers. On the other hand, borohydride reduction gives just a single product. [Pg.637]
