Timing of the work

Hyun et al. [21] evaluated both the original model by Darnell and Mol [14] and the model by Campbell and Dontula [19] for accuracy against experimental data, and determined that the Darnell-Mol model was less accurate than that of the Campbell-Dontula model. The incorporation of the lateral stress ratio in the calculations supported their conclusions even more. At the time of the work by Hyun et al, however, the physics for screw rotation was not well appreciated, and the evaluations for the Campbell models [23] were performed with coefficient of friction... 

At about the same time of the work on diastereoselective fluorination, chiral non-racemic N-fluoro compounds for direct enantioselective fluorination of C H acidic substrates were developed. 

One now divides Equation 10.10 by Equation 10.11, reduces and integrates from the beginning of the reaction to the time of the work up. 

The Great Work was often seen as being performed in one of two ways, the Dry Way and the Wet Way some even spoke of further methods, called the Mixed Way and the Brief Way. These various methods refer to the supposed length of time of the work, and the temperatures required to heat the matter in the flask. 

Another challenge is the concept of machine time. With the increasing capabilities of servomechanisms and computers, many machines operate semiautomatically (operator is required only to load/unload the machine) or automatically (machine loads, processes, and unloads). During the machine time of the work cycle, the operator may be able to drink coffee (personal allowance) or talk to the supervisor (delay allowance) or recover from fatigue. Thus, as a general principle, give a fatigue allowance only for the portion of the work cycle outside the machine time. 

They and their co-workers will not only be safer, their work will be easier. Easier because the same lean tools used to advance safety will have reduced the cycle times of the work they perform. This lean safety activity which engages both salaried and hourly staff, will improve safety and cycle times and help to establish a continuous improvement culture. The continuous improvement of work processes and safety can be the same activity. 

At the time of the work, only two large scale examples of the palladium-catalyzed cyanation had been reported [14, 15], and the standard method consisted of heating an aryl iodide or bromide with Pd(OAc)2, dppf, Zn(CN)2 and Zn (dust) in DMF at 80-120°C [23]. Application of these conditions on 1 g scale in the lab gave high conversion to 2, but during the 50 g scale manufacture, the reaction stopped at incomplete conversion. Even after forced conditions (>10 h at 120°C), only a 35% conversion to product was observed, together with a mixture of equal amounts of unreacted starting material and by-products. 

During electrolysis, vanadium again was extremely harmful. Concentrations less than 2 mgpl completely stopped the formation of amalgam [68]. As another example, 0.1 ppm vanadium in the brine can reduce the current efficiency by 0.7%. The fact that there are many synergistic combinations of metals puts a particular burden on the brine purification process [69]. While vanadium has pronounced effects, it is less of a practical problem now than it was at the time of the work reported here. Petrocoke was the base for the graphite used in anode manufacture and therefore the primary source of vanadium contamination. With the adoption of dimensionally stable metal anodes, vanadium contamination became a less frequent and a less serious problem. 

The system and simulation make it possible to avoid binding capital too early by giving the nunaging clerk generous procurement lead times for the availability dates of components. The simulation also calculates the demand schedule for the allocation of the bills of materials from the shorter standard operation and throughput times of the work sheets. 

At the time of the work by Alber et al. only low resolution images by ctyo-EM were available, and only roughly 5% of the individual protein sequences were structurally characterised at the atomistic level. 

The written requirement for employee emergency or fire prevention plan is based on the number of employees that are physically in a facility at any time of the working day and not on the number of employees that are employed by the employer. 

An interesting result is mean flow-time (fig. 2) and makespan (fig. 3) lower values obtained by BL3 and LOA rules, due to the knowledge in real-time of the work-center work-loads this allows to maintain balancing of work-loads (fig. 4) and to reduce WIP (fig. 5). ...
