Rail lines and highways need more improvement to improve their utility. Barge and ship terminals and bulk-storage facilities should be continually reevaluated from the safety and efficiency aspect, since even larger potential for disaster accompany larger amounts of hazardous materials. 

The following section describes the utilization of perovskite-type materials as CO oxidation catalysts, particularly emphasizing the effect of the materials composition on their catalytic efficiency. Aspects such as the participating oxygen species (adsorbed oxygen and/or bulk-mobile 0 species), surface redox properties, and the CO affinity of the considered catalysts will be discussed. 

The chemical nature of the plasticizer will strongly influence its efficiency. Aspects such as polarity, hydrogen bonding capability and density will... 

The size, geometry, and laminarity are most important for the liposome encapsulation efficiency aspects. The frame size depends on the preparation technique, including factors such as sonication times, extraction pressure, and the lipid composition [17]. 

The succeeding material is broadly organized according to the types of experimental quantities measured because much of the literature is so grouped. In the next chapter spread monolayers are discussed, and in later chapters the topics of adsorption from solution and of gas adsorption are considered. Irrespective of the experimental compartmentation, the conclusions as to the nature of mobile adsorbed films, that is, their structure and equations of state, will tend to be of a general validity. Thus, only a limited discussion of Gibbs monolayers has been given here, and none of such related aspects as the contact potentials of solutions or of adsorption at liquid-liquid interfaces, as it is more efficient to treat these topics later. 

Another aspect of my early research in Budapest was in nitration chemistry, specifically the preparation of nitronium tetrafluoroborate, a stable nitronium salt. 1 was able to prepare the salt in a simple and efficient way from nitric acid, hydrogen fluoride, and boron trifluoride. 

K AIE 20, has emerged as a highly efficient, noncorrosive, and nonhazardous flux for brazing aluminum parts of heat exchangers. Nocolok 100 Flux (Alcan Aluminum Corp.) developed by Alcan (Aluminum Co. of Canada) has been the first commercial product. Its use and mechanistic aspects of the associated brazing process have been weU documented (33—37). 

The maximum efficiency with which photosynthesis can occur has been estimated by several methods. The upper limit has been projected to range from about 8 to 15%, depending on the assumptions made ie, the maximum amount of solar energy trapped as chemical energy in the biomass is 8 to 15% of the energy of the incident solar radiation. The rationale in support of this efficiency limitation helps to point out some aspects of biomass production as they relate to energy appHcations. 

Environmental aspects, as well as the requirement of efficient mixing in the mixed acid process, have led to the development of single-phase nitrations. These can be divided into Hquid- and vapor-phase nitrations. One Hquid-phase technique involves the use of > 98% by weight nitric acid, with temperatures of 20—60°C and atmospheric pressure (21). The molar ratios of nitric acid benzene are 2 1 to 4 1. After the reaction is complete, excess nitric acid is vacuum distilled and recycled. An analogous process is used to simultaneously produce a nitrobenzene and dinitrotoluene mixture (22). A conversion of 100% is obtained without the formation of nitrophenols or nitrocresols. The nitrobenzene and dinitrotoluene are separated by distillation. 

Clinically, GM-CSF or G-CSF have been used to accelerate recovery after chemotherapy and total body or extended field irradiation, situations that cause neutropenia and decreased platelets, and possibly lead to fatal septic infection or diffuse hemorrhage, respectively. G-CSF and GM-CSF reproducibly decrease the period of granulocytopenia, the number of infectious episodes, and the length of hospitalization in such patients (152), although it is not clear that dose escalation of the cytotoxic agent and increased cure rate can be rehably achieved. One aspect of the effects of G-CSF and GM-CSF is that these agents can activate mature cells to function more efficiently. This may, however, also lead to the production of cytokines, such as TNF- a, that have some toxic side effects. In general, both cytokines are reasonably well tolerated. The side effect profile of G-CSF is more favorable than that of GM-CSF. Medullary bone pain is the only common toxicity. 

Continuous Saponification Systems. A relatively recent innovation in the production of soap, these systems have led to improved manufacturing efficiency and considerably shorter processing times. There are a number of commercial systems available even though these systems are different in design aspects or specific operations, they all saponify fats and oils to finished soap using the same general process (Fig. 3). 

A critical but often overlooked aspect of the technical service function is the value of relationships that develop between more senior members of the technical service staff and their coUeagues at customer sites. Professional relationships provide value both to suppHer and customer by virtue of the tmst and respect generated in a successhil technical service interaction, analogous to the types of mutuaUy valuable relationships that can develop between suppHer sales personnel and a customer s purchasing personnel. A more efficient process of gathering and dispersing new and usehil technical information can result from these relationships, because the persons involved work in different environments and are exposed in the course of their work to different external sources of information.
