Categories of technologies

While all of these effects are interesting from a research viewpoint, they clearly do not fall into the category of technologically useful hydrogenation methods.

Because chemical agent disposal facilities are based on one of two general categories of technology, incineration or neutralization (hydrolysis), it is necessary to address the HRAs for these facilities in a manner that recognizes these technological differences. 

Each of the three broad categories of technological innovation in healthcare under consideration also gives rise to the need for more specific ethical assessment. 

Marketing automation is a category of technology that allows companies to streamline, automate, and measure marketing tasks and workflows, so they can increase operational efficiency and grow revenue faster. 

We conclude this chapter and wrap up the last three chapters with a few remarks about the application of the ideas contained herein to polymer technology. Chapters 2-4 have been concerned with various aspects of the mechanical states of polymers. The opinion was expressed in Chap. 1 that if polymers did not possess the mechanical properties they have, this whole class of compounds might be relegated to the category of laboratory curiosities. On the basis of any number of criteria-the number of scientists employed, the number of industries involved, the number of publications released, the number of patents issued—polymer science proves to be very viable indeed. 

Typical textile fibers have linear densities in the range of 0.33—1.66 tex (3 to 15 den). Fibers in the 0.33—0.66 tex (3—6 den) range are generally used in nonwoven materials as well as in woven and knitted fabrics for use in apparel. Coarser fibers are generally used in carpets, upholstery, and certain industrial textiles. A recent development in fiber technology is the category of microfibers, with linear densities <0.11 tex (1 den) and as low as 0.01 tex. These fibers, when properly spun into yams and subsequendy woven into fabrics, can produce textile fabrics that have excellent drape and softness properties as well as improved color clarity (16). 

A fourth category of PV technologies, concentrator photovoltaics, uses small but very efficient cells Uluminated with concentrated sunlight. PV concentrators use lenses or reflective devices and track the sun through daUy cycles. The tracking maintains the concentrated light at intensities up to several hundred times normal sunlight. 

On August 23, 1978 (43 FR 37570), the EPA proposed a new approach to the control of conventional pollutants by effluent guideline hmitations. The new guidelines were known as best conventional pollutants control technology (BCT). These guidelines replaced the existing BAT limitations, which were determined to be unreasonable for certain categories of pollutants. 

EPA is required to identify alternative control technologies for all categories of stationary sources of VOC or NOj that have the potential to emit 25 tons per year or more of either pollutant. 

The most important aspect of this is that profits can be increased by either an increase in revenues or a decrease in expenses. Water treatment operations are by and large end-of-pipe treatment technologies, and hence from the standpoint industry applications that must treat water, the investments required increase expenditures and decrease profit. Municipal facilities view their roles differently, because their end-product is clean water which is saleable, plus they may have addon revenues when biosolids are developed and sold into local markets. There are different categories of revenues and expenses, and it is important to distinguish between them. 

In this chapter shock-loading methods measurement of wave profiles physical categories of detectors shock-compression gauges advances in measurement technology. 

Secondary recovery, infill drilling, various pumping techniques, and workover actions may still leave oil, sometimes the majority of the oil, in the reservoir. There are further applications of technology to extract the oil that can be utilized if the economics justifies them. These more elaborate procedures are called enhanced oil recovery. They fall into three general categories thermal recoveiy, chemical processes, and miscible methods. All involve injections of some substance into the reservoir. Thermal recovery methods inject steam or hot water m order to improve the mobility of the oil. They work best for heavy nils. In one version the production crew maintains steam or hot water injection continuously in order to displace the oil toward the production wells. In another version, called steam soak or huff and puff, the crew injects steam for a time into a production well and then lets it soak while the heat from the steam transfers to the resei voir. After a period of a week or more, the crew reopens the well and produces the heated oil. This sequence can be repeated as long as it is effective. 

There are now far more categories of additives than a few decades ago. The corresponding changes in additive technology are driven partly by the desire to produce plastics which are ever more closely specified for particular purposes. The benefits of plastics additives are not marginal. As outlined before, they are not simply optional extras but essential ingredients, which make all...
