Companion

This farewell to Sartre by his life-long companion is a true labour of love (the Listener) and an extraordinary achievement (New Statesman).

The appropriate quantum mechanical operator fomi of the phase has been the subject of numerous efforts. At present, one can only speak of the best approximate operator, and this also is the subject of debate. A personal historical account by Nieto of various operator definitions for the phase (and of its probability distribution) is in [27] and in companion articles, for example, [130-132] and others, that have appeared in Volume 48 of Physica Scripta T (1993), which is devoted to this subject. (For an introduction to the unitarity requirements placed on a phase operator, one can refer to [133]). In 1927, Dirac proposed a quantum mechanical operator tf), defined in terms of the creation and destruction operators [134], but London [135] showed that this is not Hermitean. (A further source is [136].) Another candidate, e is not unitary. 

The question of determination of the phase of a field (classical or quantal, as of a wave function) from the modulus (absolute value) of the field along a real parameter (for which alone experimental determination is possible) is known as the phase problem [28]. (True also in crystallography.) The reciprocal relations derived in Section III represent a formal scheme for the determination of phase given the modulus, and vice versa. The physical basis of these singular integral relations was described in [147] and in several companion articles in that volume a more recent account can be found in [148]. Thus, the reciprocal relations in the time domain provide, under certain conditions of analyticity, solutions to the phase problem. For electromagnetic fields, these were derived in [120,149,150] and reviewed in [28,148]. Matter or Schrodinger waves were...

At the opposite limit, where all the pores are sufficiently large that bulk diffusion controls, a similar calculation can be performed. In this case the appropriate flux relations are equation (5.29) and its companion obtained by interchanging the suffixes. For the symmetric systems considered here these may be written in scalar form ...

Parasiticides can be roughly divided according to parasites, host species, or chemical classification (see Antiparasitic agents—anthelmintics Antiparasitic AGENTS—ANTiPROTOZOALs). By any classification, these are ubiquitous in the management and control of parasites of both companion and food-producing animals (2,3). 

An innovative companion technology to SVE is radio frequency heating of the soil (42,43). Heating the soil increases the volatilization of the containments which are removed by SVE. Antennae are installed near the center of the contaminated area the radio frequency energy appHed through the anteimae heat the soil to target levels of 100 to 150°C. 

AIChE monograph Senes, AIChE, New York, 81, No. 15 (1985)]. Homotopy methods begin from a known solution of a companion set of equations and follow a path to the desired solution of the set of equations to be solved. In most cases, the path exists and can be followed. In one implementation, the set of equations to be solved, call tf x), and the companion set of equations, call it g x), are connected together by a set of mathematical homotopy equations ...

The X factor is then related to either Yl or Yq. Whichever one is chosen is multiplied by its companion pressure drop to obtain the total pressure drop. The following equation is based on points taken from the Yl and Yq curves in Perry s for both phases in turbulent flow (the most common case) ... 

This section is a companion to the section titled Fractionators-Optimization Techniques. In that section the Smith-Brinkley method is recommended for optimization calculations and its use is detailed. This section gives similar equations for simple and reboiled absorbers. 

First, the required head is calculated. Either the polytropic or adiabatic head can be used to calculate horsepower so long as the polytropic or adiabatic efficiency is used with the companion head. 

The gas horsepower is calculated using the companion head and efficiency.

This volume contains 50 articles describing analytical techniques for the characterization of solid materials, with emphasis on surfaces, interfaces, thin films, and microanalytical approaches. It is part of the Materials Characterization Series, copublished by Butterworth-Heinemann and Manning. This volume can serve as a stand-alone reference as well as a companion to the other volumes in the Series which deal with individual materials classes. Though authored by professional characterization experts the articles are written to be easily accessible to the materials user, the process engineer, the manager, the student—in short to all those who are not (and probably don t intend to be) experts but who need to understand the potential applications of the techniques to materials problems. Too often, technique descriptions are written for the technique specialist.
