In one of the earliest DFT models, the Thomas-Fermi theory, the kinetic energy of an atom or a molecule is approximated using the above type of treatment on a local level. That is, for each volume element in r space, one... [Pg.2181]

Regulations covering nonhazardous soHd waste ate mostiy at the state and local level. Some states ate starting to mn out of space for landfills. As a... [Pg.78]

Caibon tetiachloiide, as aie the other chlorinated methanes, is heavily regulated at the national, state, and local level. The manufacturing, storage, and... [Pg.532]

For the analysis heat and mass transfer in concrete samples at high temperatures, the numerical model has been developed. It describes concrete, as a porous multiphase system which at local level is in thermodynamic balance with body interstice, filled by liquid water and gas phase. The model allows researching the dynamic characteristics of diffusion in view of concrete matrix phase transitions, which was usually described by means of experiments. [Pg.420]

Mobile sources include railroad locomotives, marine vessels, aircraft, and automotive vehicles. Over the past 100 years, we have gained much experience in regulating smoke and odor emission from locomotives and marine craft. Methods of combustion equipment improvement, firefighter training, and smoke inspection for these purposes are well documented. This type of control is best at the local level. [Pg.423]

Buy-in" of facility management. Cooperation of facility-based staff and managers strongly influences the effectiveness of baseline PSM assessments. The assessment phase may be the first visible manifestation of your company s PSM initiative at the local level, and should be properly understood by those participating—especially those whose PSM activities and programs are under review. An assessment method with which local personnel are at least somewhat familiar, conducted by professionals whose skills they respect, will more likely gain buy-in and cooperation. [Pg.77]

The implementation strategy will need to be consistent with your company practices at both the corporate and local level. Consider the following ... [Pg.81]

Air pollution in the United States is regulated at federal, state, and local levels. Allowable concentrations of the major air pollutants are set by the U.S. Environmental Protection Agency (EPA) under the auspices of the Clean Air Act. States and localities implement pollution control plans in accordance with the provisions of the Clean Air Act in regions where air pollutant concentrations exceed the federal standards. Some states and localities have air pollution standards of their own, and in the past, such standards have occasionally been more stringent than those of the EPA. [Pg.51]

Besides its temperature dependence, hopping transport is also characterized by an electric field-dependent mobility. This dependence becomes measurable at high field (namely, for a field in excess of ca. 10d V/cm). Such a behavior was first reported in 1970 in polyvinylcarbazole (PVK) [48. The phenomenon was explained through a Poole-ITenkel mechanism [49], in which the Coulomb potential near a charged localized level is modified by the applied field in such a way that the tunnel transfer rale between sites increases. The general dependence of the mobility is then given by Eq. (14.69)... [Pg.568]

When examining the r vs d> behaviour of a catalytic system at a local level,... [Pg.156]

In sections 4.5.5 and 4.5.6 we have seen how the catalyst potential and work function affect the rates of catalytic reactions. We discussed in particular the r vs O dependence first at the local level (i.e. for small, e.g. 0.1-0.2 eV variations in eUwRand O) and then at the global level (i.e. for eUWRand variations as wide as the experimentally available eUWR range, typically 1.5-2 eV). [Pg.281]

The distribution of the intermolecular vector is also of value in distinguishing between smectic A and smectic B phases with the latter having long range bond orientational order [23, 24]. At the local level we can define a bond orientational order parameter, PeCn) for molecule i at position q by [25]... [Pg.76]

Pollution control and waste disposal are now under strict regulation at federal, state, and local levels. Enforcement of these regulations has also become more effective. Increased public awareness and media coverage make it difficult for today s polluter to hide behind a screen of ignorance. [Pg.55]

This act completely reformed arrangements for controlling pollution at national and local levels and created a complete interlocking framework for pollution control. It introduced integrated pollution control (IPC), a new approach with waste minimization at its centre and a commitment to higher environmental standards via the concept of the best practical environmental option (BPEO). The reform of waste disposal is designed to minimize waste and maximize recycling. [Pg.354]

Pollution, especially at the local level, is minimized since, from a hydrogen-powered cell, the only by-product is water. [Pg.178]

Excellent biological arguments exist for a direct impact of fever specifically on neurological outcome. On a local level, fever produces increased levels of excitatory amino acids (e.g., glutamate and dopamine), free radicals, lactic acid, and pyr-uvate. There is an increase in cell depolarizations and BBB breakdown. Enzymatic function is impaired and cytoskeletal stability reduced. These events lead to increased cerebral edema, with a possible reduction in CPP as well as larger volumes of ischemic injury. " ... [Pg.168]
