Descriptions and analyses

Flanagan FJ (1976) U.S. Geological Survey Professional Paper 840 Descriptions and analyses of eight new USGS rock standards. U.S. Government Printing Office Wash DC, 191pp. [Pg.231]

This paper presents seven potential accident scenarios in two categories. The categories are dubbed as i) discontinuous reactor accidents ii) reaction chamber rupture events. Brief qualitative descriptions and analyses of these accident scenarios are presented. Additionally, a scheme is proposed for modelling scenarios where a reaction chamber rupture is present. [Pg.385]

The aim of the descriptions and analyses presented in the foregoing sections was to illuminate some aspects of chemical lasers as molecular systems far from equilibrium. Particular emphasis was drawn on the limits of weak and strong rotational coupling since they represent extremely different kinetic schemes and consequently different kinetic behaviors. Thermodynamic considerations were employed to complement the detailed kinetic description. The thermodynamic approach can yield additional physical insights, but (at least so far) not new quantitative data. These are... [Pg.80]

These reservoirs are described using well log, core description and analyses of fluids therein. The well log interpretation was done using LOGCALC. Various reservoir parameters were evaluated to (i) characterize each pay zone, (ii) correlate lithofacies distributions (iii) estimate hydrocarbon in place, and (iv) environment of deposition. [Pg.105]

For descriptions and analyses of bond futures contracts, basis, implied repo, and the cheapest-to-deliver bond, see Burghardt et al. (1994). Fiona (1996) is a readable treatment of the European government bond basis. [Pg.455]

Conflict resolution, relative scheduling, relative control synthesis and optimization are formulated on a constraint graph model that is derived from the sequencing graph model under detailed timing constraints. Descriptions and analyses of these formulations are presented in subsequent chapters. [Pg.46]

Prior to beginning any training activity, exact training needs should be identified. Training needs may vary based on hazards, potential exposures, work requirements, roles and responsibilities, job descriptions, and compliance requirements. Job hazard analyses and employee surveys... [Pg.100]

Even, limited PSAs use and contain much information. This information may come as memos and process reports and flow sheets, equipment layout, system descriptions, toxic inventory, hazardous chemical reactions, test, maintenance and operating descriptions. From this, data and analyses are prepared regarding release quantities, doses, equipment reliability, probability of exposure, and the risk to workers, public, and environment. An executive summary analysis is detailed, and recommendations made for risk reduction. Thus the information will be text, calculations of envelope fracture stresses, temperatures, fire propagation, air dispersion, doses, and failure probabilities - primarily in tabular form. [Pg.300]

Reversed-phase HPLC followed by post-column derivatization and subsequent fluorescence detection is the most common technique for quantitative determination of oxime carbamate insecticides in biological and environmental samples. However, for fast, sensitive, and specific analysis of biological and environmental samples, detection by MS and MS/MS is preferred over fluorescence detection. Thus, descriptions and recommendations for establishing and optimizing HPLC fluorescence, HPLC/ MS, and HPLC/MS/MS analyses are discussed first. This is followed by specific rationales for methods and descriptions of the recommended residue methods that are applicable to most oxime carbamates in plant, animal tissue, soil, and water matrices. [Pg.1147]

In order to demonstrate the use of the analysis flow scheme of Figure 35, one of the accidents from the FACTS database is described and analysed according to this analysis flow scheme. The accident description in the FACTS database is very detailed and only a summary is given here. [Pg.113]

Table 2.8. Typical issues addressed when designing a clinical trial protocol. The trial objectives should clearly define what questions the trial should answer. The study design section should contain comprehensive information detailing trial size, criteria used to choose the study population, and enrolment procedures. Description of intervention section should give the background to the intervention itself, its therapeutic rationale and how it is to be administered. Measurement of response should detail the data to be collected, how it will be collected and analysed. The organization and administration section should give full details of all the investigators, where the trial is being run, and its project management details... Table 2.8.

Since band theory has proved an invaluable tool for the description of the light actinide solids. Sects. 1 and 2 will be devoted to the band description and to its limits. Sect. 3 analysing in more details the band one-electron Hamiltonian, and the ways it can be written in order to take into account electron-electron interaction. [Pg.22]

Any pulse can be described both in the time domain and in the frequency domain. In the time domain a signal may be oscillatory. The time domain behaviour is what is seen on an oscilloscope screen, because an oscilloscope is essentially an instrument for displaying a signal as a function of time. But a varying signal may also be described in terms of the components of each frequency present. This is a frequency domain description and is what is displayed by a spectrum analyser, just as an optical spectrum indicates the amount of each frequency (or wavelength) in a source of light. These two descriptions are related by a Fourier transform (Bracewell 1978), which may be written... [Pg.61]

TiTany commercial uses of carbohydrates depend upon reversible inter- actions of the hydroxyl groups with ions to form complexes. The processes are intricate, and analyses of the equilibria involved have been difficult or impossible (I). For example, the nature of the complexes involving polysaccharides and polyanions, such as borate, can only be hypothesized (2). Similarly the gelling of pectates with Ca(II) (3), the reactions of heptono-y-lactones with Fe(III), or the nature of Fe(III)-dextran complexes in intramuscular injectable solutions are awaiting proper description. Although the systems involving monomeric components are more amenable to study, as for the reactions of metal salts or hydroxides with monosaccharides or their simple derivatives (4,5, 6, 7)... [Pg.205]

Most of the time-resolved emission spectroscopy setups are home made in the sense that they are built from individual devices (laser, detection system,. ..) hence they are not of a plug and press type, so that their exact characteristics may vary from one installation to the other. Some of these differences have no impact on the overall capabilities of the system but some have a drastic influence on the way the collected data are processed and analysed. This aspect will be detailed in the next section, while this section deals with a general description of the apparatus. The most basic type of apparatus will be described, with no reference to sophisticated techniques such as Time Correlated Single Photon Counting or Circularly Polarized Luminescence devices. [Pg.469]
