Just as it is not fruitful to view a basketball team as a thing, but rather as a system with interactive components, it is fruitful to view the culture of a social unit as a system made up of four interacting subsystems (Eigure 4.5). A culture/cultural system s ideational subsystem (I) consists of the social unit s characteristic ideational constructs (ideas, values, core beliefs, ideals, worldviews, etc.). Its social subsystem (S) consists of the social unit s characteristic societal forms, (social institutions, social structure, social status system, social groups, societal traditions, social roles, etc.). Its material subsystem (M) consists of the social unit s characteristic technological artifacts and characteristic ways of making them. Its personality/behavior subsystem (P/B) consists of the social unit s characteristic personality traits and related behavior patterns. 

Near-Net-Shape Manufacturing Light depth of cut applications with close tolerance requirements, such as near-net-shape parts, are well suited for cermets because of their unique performance characteristics. Technological advances in the forging and casting industries permit production of raw products that require minimal material removal during machining operation. 

The fast reactor database (FRDB) summarized in this report is very detailed. It includes operational parameters, physical, hydraulic and thermomechanical characteristics, technological requirements, methods and criteria to ensure safe operation design data like dimensions, materials information and main design features and performance parameters of reactor cores, components, and various systems, along with sketches and drawings.

In the future it will be difficult to avoid deterioration of certain characteristics such as viscosity, asphaltene and sediment contents, and cetane number. The users must employ more sophisticated technological means to obtain acceptable performance. Another approach could be to diversify the formulation of heavy fuel according to end use. Certain consuming plants require very high quality fuels while others can accept a lower quality. 

The results of both experiments showed that the analysis in the frequency domain provides new technological possibilities of testing characteristics of austenitic steels. Using known phase-frequency characteristics of structural noises it is possible to construct algorithms for separation of useful signal from the defect, even through amplitude values of noise and signal are close in value. 

In developing the procedure of testing the features of NDT technological process must be taken into account, particularly, availability of the object for testing, strict characteristics of NDT devices being used and other factors which influence on the accuracy and reliability of measurements.

Sasol produces synthetic fuels and chemicals from coal-derived synthesis gas. Two significant variations of this technology have been commercialized, and new process variations are continually under development. Sasol One used both the fixed-bed (Arge) process, operated at about 240°C, as weU as a circulating fluidized-bed (Synthol) system operating at 340°C. Each ET reactor type has a characteristic product distribution that includes coproducts isolated for use in the chemical industry. Paraffin wax is one of the principal coproducts of the low temperature Arge process. Alcohols, ketones, and lower paraffins are among the valuable coproducts obtained from the Synthol process. 

Boron trifluoride is also employed in nuclear technology by uti1i2ing several nuclear characteristics of the boron atom. Of the two isotopes, B and B, only B has a significant absorption cross section for thermal neutrons. It is used in " BF as a neutron-absorbing medium in proportional neutron counters and for controlling nuclear reactors (qv). Some of the complexes of trifluoroborane have been used for the separation of the boron isotopes and the enrichment of B as (84). 

A number of thermally stable polymers have been synthesized, but in general the types of stmctures that impart thermal resistance also result in poor processing characteristics. Attempts to overcome this problem have largely been concentrated on the incorporation of flexible groups into the backbone or the attachment of stable pendent groups. Among the class of polymers claimed to be thermally stable only a few have achieved technological importance, some of which are polyamides, polyimides, polyquin oxalines, polyquinolines, and polybenzimidazoles. Of these, polyimides have been the most widely explored. 

HoUow fibers can be prepared from almost any spiunable material. The fiber can be spun directly as a membrane or as a substrate which is post-treated to achieve desired membrane characteristics. Analogous fibers have been spun in the textile industry and are employed for the production of high bulk, low density fabrics. The technology employed in the fabrication of synthetic fibers appUes also to the spinning of hoUow-fiber membranes from natural and synthetic polymers. 

At still higher temperatures, when sufficient oxygen is present, combustion and "hot" flames are observed the principal products are carbon oxides and water. Key variables that determine the reaction characteristics are fuel-to-oxidant ratio, pressure, reactor configuration and residence time, and the nature of the surface exposed to the reaction 2one. The chemistry of hot flames, which occur in the high temperature region, has been extensively discussed (60-62) (see Col ustion science and technology).
