Consequences Consideration

Insomnia is a related psychiatric illness having potentially serious consequences. In any given year up to one-third of the general population may experience insomnia and consequently considerable impact on quaUty of life. Potentially serious psychosocial, health, and socioeconomic consequences may foUow. Many sedative—hypnotics additionally have a firmly estabUshed position within the field of anesthesiology as premedication, inducing agents, and/or for maintenance in intensive care medicine. 

Protective group numbers in the Reactivity Charts are not continuous, since not all of the protective groups described in the text are included in the charts. The protective groups that are included in the Reactivity Charts are in general those that have been used most widely consequently, considerable experimental information is available for them. 

As a consequence considerable interest was shown in the trans-polypen-tenamer by Bayer as a potential general purpose rubber and particularly as a tyre rubber. In the event this hope did not materialise, apparently due to the following... 

Carbenes play important roles both as reactive intermediates and also as ligands consequently, considerable effort has been devoted to understanding their molecular and electronic structures. Special interest is associated with carbenes that feature the attachment of donor groups to the carbenic carbon since they behave as nucleophiles and, in some instances, can be isolated. Pioneering work on nucleo-... 

Over the last decade, interest in release and delivery of VOCs has been steadily growing, with a particular focus on food, environmental and medical applications [186-190]. Consequently, considerable effort was invested to develop analytical methods capable of capturing such dynamic VOC release processes (Fig. 15.14) [179, 191]. This led to improvements in electronic sensor methods (often termed electronic noses ) [192]. 

In some protein sources storage protein may be isolated from non-storage protein, or acid-precipitated proteins isolated from whey proteins. In the preparation of classical protein isolates by solubilization and acid precipitation, the amino acid make-up of the isolate differs from that of the extract. Consequently, consideration must be given to the amino acids chemically present in a refined protein. 

The two aldotetroses, erythrose and threose, differ from the other aldoses in their behavior.23 Ring formation, to give furanoses, can occur only through the primary hydroxyl group, and is therefore less favored than with the higher sugars. Consequently, considerable proportions of the aldehydo and aldehydrol forms are found in solution. Like all a- and /J-hydroxyaldehydes, the aldehydo form of the aldotetroses readily forms dimers in concentrated solutions of the tetroses, the signals of the dimers are readily visible in their n.m.r. spectra. In the syrupy state, the tetroses consist mainly of dimers, rather than of furanoses they have never been crystallized. 

In order to better understand nonmethane hydrocarbon involvement in the processes outlined in Figure 1, researchers are using sophisticated air-quality simulation models. These models usually require individual species information. Consequently, considerable effort is currently being directed toward the development and validation of analytical methods for measuring the concentrations of vapor-phase organic compounds in various environments. 

Relevant original papers are to be found in a wide range of journals covering many disciplines. Consequently, considerable use has been made of the excellent review series edited by Sigel1 and of the annual review2 Amino Acids, Peptides and Proteins interested readers are referred to these for up-to-date information. 

Although supplier engineering contracts are usually fulfilled on satisfactory completion of the SAT, the performance of a computer system over a spread of data-handling conditions in the real-time environment of a manufacturing process is difficult to fully test at any one time. Consequently, consideration should be given to extending contractual conditions related to system performance into the system operational period, where the broader system performance issues can be better evaluated and reported. 

The ability of lipid vehicles (either in the pharmaceutical formulation or in food) to enhance the absorption of lipophilic drugs has been well known for many years. Recently, successful bioavailability enhancement utilizing lipid-based formulations has been accomplished with the immunosuppressive agent cyclosporine A (Neoral, Novartis Pharmaceuticals Corporation, East Hanover, NJ), and for the two HIV protease inhibitors ritonavir (Norvir, Abbott Laboratories, IL) and saquinavir (Fortovase, Roche Pharmaceuticals, Nutley, NJ). Consequently, considerable interest in lipid-based formulations has been aroused. 

Raman spectra). The lifetime of the clusters is of the order 10"n to 10-12 s, so that by superimposing many representations of the V-structure we obtain the D-structure. The co-operative hydrogen bonding may be one reason for the differences between relaxation times obtained by different techniques (Frank, 1973) so comparison between experiment and theory is not straightforward. However, X-ray scattering data show that water does not exist as distinct patches of dense and bulky water. Consequently considerable interest has been shown in interstitial models for water (Samoilov, 1965). 

The composition of bulk fat is uniform, but differences from globule to globule are known to occur (see Section 5.3) consequently, considerable differences may occur in the final melting point of the fat between different globules. 

Some of these catalyze the smooth racemization of chiral secondary alcohols at room temperature. However, a major problem which needed to be solved in order to design an effective combination of ruthenium catalyst and lipase in a DKR of secondary alcohols was the incompatibility of many of the ruthenium catalysts and additives, such as inorganic bases, with the enzyme and the acyl donor. For example, the ruthenium catalyst may be susceptible to deactivation by the acetic acid generated from the acyl donor when it is vinyl acetate. Alternatively, any added base in the racemization system can catalyze a competing selective transesterification of the alcohol, resulting in a decrease in enantioselectivity. Consequently, considerable optimization of reaction protocols and conditions was necessary in order to achieve an effective DKR of secondary alcohols.
