LABOR productivity, ELASTOMERS, POLYMERS, VISCOSITY, and SHEAR flow
The article discusses the next generation of Zetpol elastomers which possess necessary processing characteristics to achieve improved productivity. It provides a comparison between two polymers such as the Z-2010EP and Z-2010L which clearly demonstrate comparable cured property performance. Result shows that the Z-2010Ep compound will provide a manufacturer faster cycle times by increasing the mold temperature in order to take full advantage of the improved flow.
RUBBER industry, POLYMER viscosity, INJECTION molding of rubber, AUTOMOBILE part design & construction, and HEAT resistant materials
The article focuses on the use of low viscosity hydrogenated nitrile butadiene rubber (HNBR) polymers. It notes that low viscosity HNBR polymers are applicable in injection molding process in creating small automotive parts. It presents data on the testing of the compound rheological properties of the material. It notes that HNBR polymers used in oilfield must withstand extreme heat and pressure.
COMPUTER software, COMPUTER input-output equipment, INTEL microprocessors, MICROPROCESSORS, and VIRTUAL machine systems software
As use of Intel® Virtualization Technology for IA-32 and Intel 64 Architectures (Intel® VT-x) has grown, the demand for improved performance in virtualized systems has increased. The Intel® microarchitecture code name Nehalem and Intel® microarchitecture code name Westmere, have introduced extensions to Intel VT-x and its underlying hardware support to meet these increasing performance demands. This article discusses the architectural and microarchitectural improvements provided by these processors and how they translate into improved performance for software that uses this technology.

ELASTOMERS, POLYMERS, RUBBER, INJECTION molding of rubber, ANTIOXIDANTS, and PLASTICS
The article discusses the development of Zeon HT-ACM elastomers and associated materials. The authors explain that the improved Zeon HT-ACM elastomers can meet the high-temperature performance requirements of applications. Moreover, these elastomers were designed to be fast curing for injection molding processes. Furthermore, they are intended to evaluate cure systems and antioxidants systems.
RUBBER industry, POLYBUTADIENE, ARTIFICIAL rubber, PEROXIDES, INJECTION molding of plastics, and VISCOSITY
The article focuses on the study about compounding techniques for an improved Hydrogenated Nitrile Butadiene Rubber (HNBR) compounds. The objective of the study is to see the comparison between scorch retarded peroxides and the traditional non-retarded counterparts in determining the impact of injection molding operations. It was found out that co-agents are very important factor for improving the processing of compounds by lowering its viscosity.
WASTE management, HAZARDOUS substances, DEMOGRAPHIC surveys, ENVIRONMENTAL risk assessment, DEMOGRAPHIC transition, ENVIRONMENTAL sociology, RACISM, ROLE playing, and SOCIAL groups
This article discusses he concept of "environmental equity" which assessing demographics concerning the treatment, storage and disposal of hazardous wastes (TSDF). Recent evidence of environmental inequity comes from a variety of studies showing that environmental risks, known or potential, are distributed differently across demographic groups. There are two major issues of debate in this context: first, the environmental racism and second, regarding TSDF. The often heated debate concerning TSDF has focused on inequity and on the potentially discriminatory nature of facility locations. Although inequitable distributions are not conclusive evidence of intentional prejudice, it is desirable to understand and document the distribution of facilities and the precise nature of any inequity across social groups, which is the main concern of this article. The first step in a geographic analysis is suggested to determine the appropriate area to be used as a unit of analysis. It is suggested that the judgment of equity then rests on prejudice and undue risk or harm. Demographic studies, however, play a critical role in assessing the equitable distribution of such facilities and evaluating prejudicial exposure to potential harm or benefit.
ECONOMICS, ECONOMIC development, ECONOMIC sectors, ECONOMIC systems, and WELL-being
Disarticulation refers to the juxtaposition of economic sectors with different levels of development and productivity. Disarticulation is hypothesized to have a negative effect on social well-being, net of economic development, because it inhibits the spread effects generally thought to be associated with economic growth. Findings are in accord with this hypothesis, although the relationship is complex. The strongest effects of disarticulation are found among the poorest nations. The concept of disarticulation opens a new and promising avenue of research that may help to resolve contradictory findings of recent research on the political economy of growth.
