Shortest processing time

Acetonitrile, acetone, ethanol, and methanol have been used to extract isoflavones from soy foods. Among them, acetonitrile proved to be the most efficient (Griffith et al., 2001 Murphy et al., 2002). The solvent is supplemented with 0.1 M HC1 to completely un ionize the isoflavones and to release them from protein complexes by denaturing and precipitating the proteins. Room temperature is recommended for extraction to avoid alteration of the natural forms of the isoflavones. The time for extraction, 2 hr, was chosen for maximum recovery and shortest processing time. Ultrasound is used to aid the extraction process by degrading and weakening the cellular matrix. 

The dwell time of regular bronze pigments in the processing units should not exceed 5 min. It is recommended the shortest processing time for optimum gloss, brilliance, and homogeneity be determined. 

To save cost and time, the tools and services in a development process should be executed as efficiently as possible, i.e., if there are several instances of a service that could be integrated, the cheapest one or the one with the shortest processing time should be used. 

For problems that are solvable in polynomial time, it is usually relatively easy to find efficient algorithms. For the simplest of these problems, a simple sort is all that is required. For example, it may only be necessary to order the jobs in increasing order of their due dates (the so-called earliest due date rule [EDD]) or in decreasing order of the Wjlpj ratios (the so-called weighted shortest processing time [WSPT] first rule. For more complicated polynomial time problems, more sophisticated techniques such as dynamic programming are required. 

Consider the problem Pm prmp a Cj + a C, that is, there are m identical machines in parallel with preemptions allowed and as the objective the minimization of a weighted sum of makespan and flow time. It can be shown fairly easily that the shortest processing time first (SPT) rule minimizes SCj on parallel machines, while the preemptive longest remaining processing time first (preemptive LPT) rule minimizes Because these two rules are quite different, it is not immediately obvious what type of rule minimizes a mixture of these two objectives.

Experienced color matchers can achieve a good color match by trial and error without using any instmmentation. In some cases, however, this technique can be a lengthy process, and should the desired match be outside the color space defined by the available color standards, the technician might spend too much time just to determine that the match is not possible. To get the most cost-effective match using a low metamerism in the shortest possible time, the use of a computet color matching system is preferable. 

Cleaning times are easily accounted for in both policies. The method of search for the shortest cycle time does not change in the case of the ZIV policy if non-zero cleaning times are considered. The slacks can also be easily calculated a priori with non-zero cleaning times. In case of the UIS policy, cleaning times must simply be added to the processing times ... 

As indicated in Table 5.5, the addition of an inorganic salt appears to improve the yields of the A-alkylated hydrazobenzenes by a common ion effect. In the absence of the inorganic salt, the best yields in the shortest reaction times are attained when chlorobenzene is used as the organic phase. Stoichiometric amounts of the catalyst are used in this reaction and it is conceivable that either the solid liquid or the liquiddiquid two-phase conditions, with a catalytic amount of the ammonium salt, as used in the A-alkylation of the triazenes, may be a more effective process. 

First, 400 kg of finely divided salt with a water content of about 8 % by mass is to be dried in the shortest possible time (about 1 h) until the water content is less than 1 % by mass. The expected water evolution amounts to about 28 kg. The salt in the chamber is continuously agitated during the drying process and heated to about 80 °C. The vacuum system is schematically drawn in Fig. 2.78. 

Solvation in water was extensively studied and processes on different timescales were described ranging from 30 fs to several ps [8]. Due to our experimental resolution the shortest decay time we measure contains various superimposed contributions from the ultrafast processes presumably the inertial response of water and initial librational motions of molecules in the first solvation layer. 

The resources responsible for implementing SCM techniques and processes should be chosen carefully and developed using a train-the-trainer concept, and should regularly be assigned to subsequent sub-projects within the program, to achieve the highest impact in the shortest possible time. 

To 0.5 g. of potassium hexachloroplatinate(IY) in a quartz or Kel-F bottle, about 5 ml. of Freon 113 (CC12F—CC1F2) is added to act as moderator. Excess bromine trifluoride (1-2 ml.) is then added dropwise in the shortest possible time (a quartz or Kel-F rod may be used to assist pouring) until solution of the chloroplatinate is complete (bromine trifluoride and Freon 113 are immiscible). It is the aim of this procedure to combine minimum reaction time with minimum local heating of the mixture. It is usually necessary to shake the bottle ( care should be taken to avoid spills) to aid the solution process. As...
