Demand, the

Production levels will be influenced by external factors such as agreed production targets, market demand, the level of market demand for a particular product, agreements with contractors, and legislation. These factors are managed by planning of production rates and management of the production operation. 

A single cut of the tested object is generated in a single scan. Generation of additional cuts demands the repetition of the exposure. 

The construction of an aberration-corrected TEM proved to be teclmically more demanding the point resolution of a conventional TEM today is of the order of 1-2 A. Therefore, the aim of a corrected TEM must be to increase the resolution beyond the 1 A barrier. This unplies a great number of additional stability problems, which can only be solved by the most modem technologies. The first corrected TEM prototype was presented by Flaider and coworkers [M]- Eigure BE 17.9 shows the unprovement in image quality and interpretability gained from the correction of the spherical aberration in the case of a materials science sample. 

Sofh are applications can mainly be divided into stand-alone programs that have to be installed on a local computer, and web-based appUcation.s. Furthermore, there arc two different tcchniquc.s u.scd in web-based applications for providing the programs applets and plug-ins. Whereas plug-ins (helper applications) have to be installed to be displayed correctly in a browser, java applets are loaded by the browser on demand. The basic requirement for executing java applets is that the java Virtual Machine (jVM) must be pre-installed on the local computer, which is oltcn the case. 

The most satisfactory and the most accurate method for the calibration of a thermometer is to compare it directly with short-scale thermometers, each of limited range, which have been standardised at the National Physical Laboratory.f The comparison should be made as far as possible under the same conditions as the thermometer is to be used. For experiments demanding the highest precision e.g., in research work), it is a good plan to have two similar sets of short-scale thermometers, one of which has been standardised at the N.P.L. the unstandardised set is... 

For ionic reactivity two cases must be considered depending on the electron demand the thiazole ring may either be electron donating or electron accepting. 

The ceUulose polymer and its conversion routes have already proved to be capable of adaptation to meet a wide range of market demands. The advances being made in getting ceUulose into solution with minimal environmental impact augur weU for the development of streamlined routes from tree to fiber or fabric. 

This example demonstrates the most challenging problem of flavor chemistry, ie, each flavor problem may require its own analytical approach however, a sensory analysis is always required. The remaining unknown odorants demand the most sensitive and selective techniques, and methods of concentration and isolation that preserve the sensory properties of complex and often dehcate flavors. Furthermore, some of the subtle odors in one system will be first identified in very different systems, like o-amino acetophenone in weasels and fox grapes. 

Cmde oil can be easily separated into its principal products, ie, gasoline, distillate fuels, and residual fuels, by simple distillation. However, neither the amounts nor quaUty of these natural products matches demand. The refining industry has devoted considerable research and engineering effort as well as financial resources to convert naturally occurring molecules into acceptable fuels. Industry s main challenge has been to devise new ways to meet the tremendous demand for gasoline without, at the same time, overproducing other petroleum products. 

Hydrothermal Synthesis Systems. Of the unit operations depicted in Figure 1, the pressurized sections from reactor inlet to pressure letdown ate key to hydrothermal process design. In consideration of scale-up of a hydrothermal process for high performance materials, several criteria must be considered. First, the mode of operation, which can be either continuous, semicontinuous, or batch, must be determined. Factors to consider ate the operating conditions, the manufacturing demand, the composition of the product mix (single or multiple products), the amount of waste that can be tolerated, and the materials of constmction requirements. Criteria for the selection of hydrothermal reactor design maybe summarized as... 

Uses. Currentiy, the principal use of lactic acid is in food and food-related applications, which in the United States accounts for approximately 85% of the demand. The rest ( 15%) of the uses are for nonfood industrial applications. The expected advent of the production of low cost lactic acid in high volume can open new applications for lactic acid and its derivatives, because it is a versatile molecule that can be converted to a wide range of industrial chemicals or polymer feedstocks (1,6,20). 

Indium prices vary by purity level according to the number of mines. For 99.97 or 99.99% pure indium Meta/Bu//etm magazine s free-market prices ranged from 160 to 190/kg in 1993. Prices have trended downward since 1988. This, coupled with the fact that consumption increased during this period, is evidence that supply is ahead of demand. The most notable production increases have occurred at Indium Corp. of America, Nippon Mining Co. Ltd., Cominco Ltd., and Metaleurop S.A. The largest increase was made by Indium Corp. A 30-t increase was announced in 1988 in 1993 Indium Corp. announced plans to increase production by another 30 t to be phased in with demand, bringing the company s actual and planned increases to 60 metric tons over the 1988 level. 

Demand. The demand for uranium in the commercial sector is primarily determined by the requirements of power reactors. At the beginning of 1993, there were 424 nuclear power plants operating worldwide, having a combined capabity of about 330 GWe. Moderate but steady growth is projected for nuclear capacity to the year 2010. The capacity in 2010 is expected to be about 446 GWe (29). 

Other factors that affect either production cost or the consumption of fertilisers tend to be periodic and short-Hved. On the consumption side, weather conditions, prices of fertilisers, and the pohtical stabiUty of a region influence demand. The supply side is influenced by raw material availabihty, rehabihty of infrastmcture, on-stream efficiency, age of plants, and the constmction or modernisation of existing plants. 

Paper Products. Paper (qv) products account for about 2% of sulfur demand. The largest single segment of demand is in the manufacture of wood pulp by the sulfite process (see Pulp). In this process, the main sulfur intermediate is sulfur dioxide, which is generally produced at the plant site by burning elemental sulfur. Some sulfur dioxide, however, is produced as a by-product at smelter operations, purified andUquefied, and shipped to the pulp mills. The sulfur dioxide is converted to sulfurous acid, and the salt of this acid is a principal component of the cooking Hquor for the sulfite process.
