Increasing Availability

Up-to-day reliability requirements as applied to NPP strength maintenance govern development of new generation of computerized systems for in-service inspection. These systems in parallel with capabilities of ordinary ultrasonic techniques allow to reconstruct high resolution image of inner flaw and increase available amount of information. 

A more elaborate theoretical approach develops the concept of surface molecular orbitals and proceeds to evaluate various overlap integrals [119]. Calculations for hydrogen on Pt( 111) planes were consistent with flash desorption and LEED data. In general, the greatly increased availability of LEED structures for chemisorbed films has allowed correspondingly detailed theoretical interpretations, as, for example, of the commonly observed (C2 x 2) structure [120] (note also Ref. 121). 

Scientific, and especially chemical, information is becoming increasingly available on the Internet. This has the advantage that the information is accessible to other users. Additionally, the data formats (HTML, PDF, GIF, etc.) that are used are restricted to the most important ones to provide standards that are readable worldwide. Unfortunately, however, much of the information on the Internet is not reviewed or verified by other organizations as is the case in the primary literature. Thus, the quality of the information is extremely variable. 

The utility of acid-base titrimetry improved when NaOH was first introduced as a strong base titrant in 1846. In addition, progress in synthesizing organic dyes led to the development of many new indicators. Phenolphthalein was first synthesized by Bayer in 1871 and used as a visual indicator for acid-base titrations in 1877. Other indicators, such as methyl orange, soon followed. Despite the increasing availability of indicators, the absence of a theory of acid-base reactivity made selecting a proper indicator difficult. 

Carbon electrodes are the normal choice for the link in the connection chain to deflver power to the arc tip. Graphite may be used in special apphcations, but the higher cost of graphite favors the use of carbon electrodes. Carbon possesses properties ideal to its appHcation as an electrode. These properties include no softening point, no melting point, electrical conductivity, strength increases with increasing temperature, resistivity drops as temperature increases, available in the size and purity desired, and cost effectiveness. 

Inductively coupled plasma-mass spectrometry (ICP-MS) is a multielement analytical method with detection limits which are, for many trace elements, including the rare earth elements, better than those of most conventional techniques. With increasing availability of ICP-MS instalments in geological laboratories this method has been established as the most prominent technique for the determination of a large number of minor and trace elements in geological samples. 

Algorithms and computer hardware have limited the size of most of the all-atom membrane simulations performed to date to 50-100 lipids plus water. However, with the increasing availability of parallel computers, larger systems containing up to 1000 lipids are starting to be simulated [75], and systems containing more than 100 lipids will soon be routine. 

Labor Expenses. In the majority of situations, projects will cause a company s labor requirements to change. This change could be a positive effect that increases available productive time, or there could be a decrease in employees production time depending upon the practice. When computing labor expenses, the Tier 1 costs could be significant. Labor expense calculations can be simplistic or comprehensive. The most direct and basic approach is to multiply the wage rate by the hours of labor. More comprehensive calculations include the associated costs of payroll taxes, administration, and benefits. Many companies routinely track these costs and establish an internal burdened labor rate to use in financial analysis. 

Available horsepower from a gas turbine is a function of air compressor pressure ratio, combustor temperature, air compressor and turbine efficiencies, ambient temperature, and barometric pressure. High ambient temperatures and/or low barometric pressure will reduce available horsepower while low ambient temperatures and/or high barometric pressure will increase available horsepower. All industrial turbines will have high-temperature protection, but in areas subject to very low ambient temperatures horsepower limiting may be required. 

Parallel with these trends and related to them is the increase in chemical reactivity which is further enhanced by the increasing bond polarity and the increasing availability of low-lying vacant orbitals for energetically favourable reaction pathways. 

The increased availability of energy fueled the Industrial Revolution. The United States became the world s largest oil producer, and the new fossil fuels were abundant and modestly priced. A technology s energy efficiency was not a key part of capital investment decisions. Energy-efficient technology as a priority ranked well behind improved performance. 

Additionally, new supplies of natural gas from Canada and Alaska could significantly increase available supply, along with imports of Mexican gas and the potential for liquefied natural gas from overseas. 

Thus, while titanium and zirconium were primarily developed for specific purposes, their increasing availability in commercial quantities made it economically possible for the chemical industry to take advantage of their exceptionally good corrosion resistance. 

Unfortunately, nicandrenone is typical of many instances in the field of natural pesticides where elucidation of chemical structure has not previously received the attention it deserves. However, with the increased availability of powerful instrumental techniques, considerable progress has been made during the past decade. Since the last general review (14), active principles from several more of the time-honored insecticidal plants have yielded to structure elucidation (Table I). 

At present, the major effort to develop anti-pollution coating systems is devoted to outside lithographic decorating materials for beverage and non-food containers. Water-based, clear varnishes and white coatings are increasingly available for specific end uses. Significant advances are... 

Plants may be affected by indirect modifications of the environment. Soil acidification, for example, can cause the leaching of nutrients, and the release of toxic aluminum. These effects may operate together to produce nutrient deficiencies or imbalances to plants. High soil concentrations of aluminum may prevent uptake and utilization of nutrients by plants.Increased availability of aluminum in soils has been implicated as a cause of forest declines in both Europe and the United States, possibly through the toxic effects on small feeder roots 14),... 

Before the advent of modem computer-aided mathematics, most mathematical models of real chemical processes were so idealized that they had severely limited utility— being reduced to one dimerrsion and a few variables, or Unearized, or limited to simplified variability of parameters. The increased availability of supercomputers along with progress in computational mathematics and numerical functional analysis is revolutionizing the way in which chemical engineers approach the theory and engineering of chemical processes. The means are at hand to model process physics and chenustry from the... 

New application of modem statistical mechaiucal methods to the description of stmctured continua and snpramolecnlar flnids have made it possible to treat many-body problems and cooperative phenomena in snch systems. The increasing availability of high-speed compntation and the development of vector and parallel processing teclmiqnes for its implementation are making it possible to develop more refined descriptions of the complex many-body systems. 

Psychosocial and environmental factors play a major role in the development and recovery from opioid dependence however, a detailed discussion is beyond the scope of this chapter. In general, the use of such drugs as marijuana and alcohol precedes the use of opioids (Clayton and Voss 1981 Kandel and Faust 1975). Although one cannot predict definitively which users will proceed to opioid use, those who do generally have low self-esteem, disrupted families, and/or difficult relationships with their parents. The increased availability of opioids in inner cities of major urban centers contributes to initiation of use and relapse. It is particularly difficult to avoid use and relapse in areas with high unemployment, poor school systems, and high crime rates, because living in such an area may contribute to the very affects opioid use temporarily reheves.
