Most biological and cultural pest controls return greater profits than pesticides. For example, biological pest controls are reported to return from 30 to 300 per dollar invested in control (16). Various cultural controls like host plant resistance, crop rotations, and tillage, also return 30 to 300 per dollar Invested in pest control (16). 

Natural pigment production for food coloration includes the entire spectrum of biotechnologies. For example, biological production of carotenoid pigments has medical implications because carotenoids are nutritive (pro-vitamin A), antioxidant, and photoprotective. Carotenoids are produced alternately in agricultural systems (plants), industrial bioreactors (bacterial and fungi), and marine systems (cyanobacteria and algae). 

ISEs are well suited for flow measurements because the instrumentation and signal handling are simple, the measurement is almost independent of the liquid flow-rate, the linear dynamic range is broad, the temperature dependence is not very pronounced and the measurement is selective (the selectivity is, however, a drawback in applications to chromatography). The experimental conditions are readily adjusted and often only consist of ionic strength and pH maintenance. ISEs with solid membranes usually exhibit better performance than liquid membrane electrodes and gas probes, because their response is faster and they are mechanically stronger. The most difficult problem is passivation of the electrodes in some media, for example, biological fluids or surface and waste waters. 

Halofluorination has also been applied to tertiary diazo compounds. For example, biologically active products 2 and 3 were prepared from esters of 6-diazopenicillanic acid not too acid-sensitive esters can be treated with A-bromosuccinimide in 70 % hydrogen fluoride/pyridine317 but acid-sensitive esters [such as (pivaloyloxy)methyl esters] must be reacted with A-bromo- or A-chlorosuccinimide in the presence of tetrabutylammonium hydrogen fluoride.318 319... 

Table 5.1 summarises the different research activities to improve the lateral resolution of LAPS. It is clearly demonstrated that the resolution can be extended down to the sub-micron range in the near future. This will broaden the possible application fields of the LAPS principle. For example, biological and chemical sensor arrays will benefit from further investigations and improvements of the lateral resolution of the LAPS. However, the LAPS works with an external light source, i.e., the experimentally applied light source, and its optical pathway will also limit the achievable resolution. 

As noted above, advances in imaging not only will benefit the chemical sciences, but also fundamental understanding in many other areas. For example, biological processes, materials, medicine, and national security provide excellent examples important application areas for advances in chemical imaging. 

It is important that the preceding speculations are true only for macroinformation— that is, information on the occurrence of one of many possible system macrostates at a given moment of time. As to microinfor mation, it cannot be fixed in principle, since any microstate may turn rap idly to another microstate due to the strong instability of microscopic motion and heat fluctuations. For example, biological and computational systems store only macroinformation (see following for details on some... 

Distributed pharmacokinetics is characterized not only by spatially dependent concentration profiles but also by dose-response relationships that become spatially dependent. For example, biological responses such as cell kill are often quantified as functions of area under the concentration-vs.-time curve (ALIC). In compartment models, response is frequently correlated with the area under the plasma-concentration-vs.-time curve, where... 

The current review is of necessity selective. Over the two year period covered, there has been impressive advances in several areas of P(V) chemistry. For example, biological aspects of quinquevalent phosphorus acids chemistry continue to increase in importance. A wide variety of natural and unnatural phosphates including inositols, lipids, some carbohydrates and their phospho-nates, phosphinates and fluorinated analogues has been synthesized. Special attention has been paid to the synthesis of phosphorus analogues of all types of amino acids and some peptides. Numerous investigations of phosphate ester hydrolysis and related reactions continue to be reported. Interest in approaches to easier detoxification of insecticides continues. A number of new and improved stereoselective synthetic procedures have been elaborated. The importance of enantioselective and dynamic kinetic asymmetric transformations is illustrated in many publications. 

Table 3.11 lists the important feedstock characteristics to be examined when developing a conversion process for a specific virgin or waste biomass feedstock. A particular process also may have specific requirements within a given process type. For example, biological gasification and alcoholic fermenta-... 

In general, it is not necessary to give detailed results of trials of use of the invention, for example, biological pharmacological or clinical results for pharmaceuticals. But sometimes, it can be useful to present comparative results between the prodncts of the application and the products of the prior art, in order to demonstrate the advantage of the invention.
