Embodied Positions

When accidents occur, investigators must transform these embodied locations into coordinate positions that can be located in relation to the numbered passages (crosscuts) on a two-dimensional map of the mine. Nagy can identify these numbered passageways because he knows the map locations of telephones, belts, and spillage sites. But he must rely on miners memories to locate their embodied positions. [Pg.142]

Data are given in Table 1 for the events occurring at Crosscut 34, where the belt from No. 5 Right dumped on to the Main North belt. Two men. Price and Tidwell, were at that location shoveling [sic] spillage. After Silsbury made his two [Pg.142]


The equation of restriction can embody causality, lower boundedness of energies in the spectrum, positive wavenumber in the outgoing wave (all these in nonrelativistic physics) and interactions inside the light cone only, conditions of mass speciality, and so on in relativistic physics. In the case of interest in this... [Pg.111]

Reproducibility was provided by the calotype" process, patented in 1841 by the English landowner W. H. Fox Talbot, which used semi-transparent paper treated with Agl and a developer , gallic acid. This produced a negative from which any number of positive prints could subsequently be obtained. Furthermore it embodied the important discovety of the latent image which could be fully developed later. Even with Talbot s very coarse papers, exposure times were reduced to a few minutes and portraits became feasible, even if uncomfortable for the subject. [Pg.1186]

Practical activities should embody as best as possible the scientifie proeesses that have been preseribed by the American Association for the Advancement of Science observation, elassification, numerieal relations, measurements, time-spaee relations, eommunieation (oral, pictorial, written), deriving of conclusions, prediction ( what would happen if. .hypothesis making, production of operational definitions, identifieation and control of variables, experiment and explanation of experimental data. Different theoretical perspectives should be used with the aim to optimize the positive eognitive and affeetive outcomes. The use, sometimes together, sometimes separately, of different perspeetives can act complimentarily and can lead to positive results (Niaz, 1993 Tsaparhs, 1997). [Pg.129]

This part of the presentation embodies first a general treatment on surfactants followed by the elaboration of frothers, collectors and regulators. The text subsequently involves the area of sulfide flotation, which occupies a premier position in the field of flotation. The section is completed with some important examples of flotation of sulfides. The final section is devoted to natural hydrophobicity which, on its own accord constitutes an important and interesting area in the field of flotation. [Pg.193]

A systematic investigation of the free amino acids of the Leguminosae led to the isolation of a novel ninhydrin-positive compound from the leaves of Derris elliptica Benth. (Papilionidae) (93). This substance was analyzed as C6H,3N04 (microanalysis and high resolution mass spectrometry) and was shown to be an amino alcohol. The absence of a carbonyl in the 1R, the loss of 31 mass units in the mass spectrum, and a positive periodate cleavage reaction were best embodied into a dihydroxydihydroxymethylpyrrolidine structure. The relative simplicity of the NMR spectra (three peaks in the 13C spectrum four spin-system in the H spectrum) pointed out a symmetrical structure. Inasmuch as the material was optically active ([a]D 56.4, c = 7, H20), meso structures were ruled out, and the 2R, 3R, 4R, 5R relative configuration was retained (93). This structure (53) was further confirmed by an X-ray determination (94). [Pg.294]

The latter result follows from the definitions embodied in equations 1.82 and 1.83. However, the mean of the square of the fluctuations is not zero. This is easily seen from the fact that, while the fluctuation takes both positive and negative values, the square of the fluctuation is always positive. Thus... [Pg.58]

The chemical industry also encourages EPA to reexamine and rescind its premanufacture Testing Policy. While ostensibly voluntary, this policy embodies the Agency s position that all, or nearly all, new chemicals should undergo a minimum "base set" of tests or, in OECD terms, a "Minimum Premarketing Set of Data" (MPD), which could greatly increase the costs of... [Pg.100]

Thus question (a) becomes free ions or ester As happens so often in scientific controversies, it appears that the truth may embody both the extreme positions. The point (ii) above shows that at least one of the active species is insensitive to water and ethanol, and points (iii) and (iv) indicate that at least under some conditions stage II is dieidic. It is fairly evident that the species which is insensitive to water and ethanol must be the ester, and that the second species which is suppressible by excess of common-ion electrolyte, and which is slowly formed during stage II, must be the free ions. [Pg.427]

Furthermore, in the new interpretation money plays a key role in defining the way in which labour power is valued.4 This is contrasted with the labour embodied approach. The usual interpretation, which posits a bundle of subsistence goods whose labour content defines the value of labour power, short-circuits this relation, and makes money disappear as a mediating element in the situation (ibid. 43). Similarly, for Mohun (1994 405), in his defence of the new interpretation, money becomes in embodied labour accounts of value an irrelevance to theoretical explanation . In addition to providing a defence of the labour theory of value, the new interpretation offers a way of modelling capitalism as a system in which surplus value is appropriated in its money value-form. [Pg.96]

This subject is concerned only with equilibrium states and never with the rate of a process. Its basic principles are embodied in three well-known laws. The first of these enables us to calculate the energy change in a particular thermodynamic process, e.g. a chemical reaction, the second enables us to decide whether or not a process is spontaneous and the third permits the calculation of the position of equilibrium. In what follows, those parts of thermodynamics which are particularly relevant to the calculation of chemical equilibria will be summarised and this will be followed by an example illustrating the main points of the previous discussion. Much fuller accounts of thermodynamics are to be found in the books by Denbigh [3] and Bett et al. [4]. [Pg.5]

Also, during examination of a patent application the scope or breadth of the claims often needs to be narrowed because of prior disclosures. Any amendments to the claims must be based on the contents of the application and so, ideally, the patent application contains many layers of fall-back positions which identify useful features or preferred variants of the invention ranging from the full scope of the claimed invention which was initially considered to be justified, down to the specific embodiments described. [Pg.451]

It has already been mentioned that the elements may be divided into two great classes, the metals and the non-metals or metalloids. A second division into positive or basylous and negative or chlorous elements has also been explained. A thi and still more important classification is founded upon the atomicity of the elements. In the following classified Table all three methods are embodied, the metalloids being printed... [Pg.41]
