Efficiencies of complexes

Further evidence for an increased efficiency of complexation in the presence of micellar aggregates with bivalent metal counterions is presented in Table 5.4. The apparent rate constants of the reaction of 5.1c with 5.2 in the presence of micelles of Co(DS)2, Ni(DS)2, Cu(DS)2 and Zn(DS)2 are compared to the rate constants for the corresponding bivalent metal ion - dienophile complexes in the absence of micelles. The latter data are not dependent on the efficiency of the formation of the catalyst - dienophile complex whereas possible incomplete binding will certainly be reflected in the former. The good correlations between 1 and and the absence of a correlation between and...

The efficiency of complex treatment in many cases depends on the protection level of the structure and function of cell membranes. For correction of these disorders a complex of measures, including antioxidative and enterosorption preparations, was used. By chemical binding of heavy metals pectin enterosorbent ensures fast elimination of the primary source of intoxication. 

Not surprisingly, nature is far ahead of human ingenuity - biopolymers have PDI values very close or equal to one, indicating that only one length of polymer is present -directly responsible for the high specificity and efficiency of complex living systems.

The level of mental workload experienced by operators is a key element in the safety, reliability, and efficiency of complex sociotechnical systems (Gregoriades and Sutcliffe, 2007). Mental workload is a contentious area, and there has been great debate over how to define the concept. It is generally agreed that human operators possess a finite attentional capacity and that during task performance these atten-tional resources are allocated to component tasks. Workload is thus a function of the human operator s attentional capacity and the demand for resources imposed by the task. The level of mental workload represents the proportion of resources that are required to meet the task demands (Welford, 1978). Young and Stanton (2001) formally defined mental workload as follows The mental workload of a task represents the level of attentional resources required to meet both objective and subjective performance criteria, which may be mediated by task demands, external support, and past experience. Mental workload is therefore a multidimensional construct that is characterized by the task (e.g., complexity, demands) and the individual involved (e.g., skill, experience, training). 

How to improve the computational efficiency of complex and accurate potential models Generally speaking, more complex potentials with appropriate parameterization can better reproduce a wider range of physical behaviors of a system under study, albeit often with an undesirable increase in the computational cost. Short-ranged versions of the TS potentials prove that balance between computational efficiency and model accuracy can be achieved, which is a cmcial requirement for large-scale atomistic simulations. 

PVK-Ru complexes increased with increasing w/w% of the Ru-complex [14]. The electric-field dependence of the photogeneration efficiency of complexes containing 0.028, 0.036, 0.070, and 0.891 w/w% of the Ru-complex, labeled 1, 2, 3, and 4 respectively, are shown in Figure 8.4 along with that of a PVK-TNF system.
