Staging area defined

Generally, the degree of dementia correlates with the sites and severity of tau-based NFT accumulation (Holzer et al., 1994). Based on the manner of NFT formation on various brain areas of the AD patient, during the course of disease development, six neuropathological stages are defined. 

A strategy divided into 4 stages was defined to carry out the study (1) characterization of the area and sample population (2) selection of the workstation (3) evaluation of symptoms associated with WMSDs (4) application of EWA and in case of being necessary, selection and application of methods of expert ergonomic analysis to assess the risk. 

Standardized techniques atomic absorption (AAA) and photometric (FMA) of the analysis and designed by us a technique X-Ray fluorescence of the analysis (XRF) for metals definition in air of cities and the working areas of plants to production of non-ferrous metals are applied. The samples of aerosols were collected on cellulose (AFA-HA) and perchlorovinyl (AFA-VP and FPP) filters (Russia). The techniques AAA and FMA include a stage of an acid-temperature ashing of a loaded filter or selective extraction of defined elements from filter by approaching dissolvent. At XRF loaded filters were specimens. 

Clearly, the maximum degree of simplification of the problem is achieved by using the greatest possible number of fundamentals since each yields a simultaneous equation of its own. In certain problems, force may be used as a fundamental in addition to mass, length, and time, provided that at no stage in the problem is force defined in terms of mass and acceleration. In heat transfer problems, temperature is usually an additional fundamental, and heat can also be used as a fundamental provided it is not defined in terms of mass and temperature and provided that the equivalence of mechanical and thermal energy is not utilised. Considerable experience is needed in the proper use of dimensional analysis, and its application in a number of areas of fluid flow and heat transfer is seen in the relevant chapters of this Volume. 

Environmental Fate. Having characterized the entry of materials into the environment, we move into the second step of our procedure. The goal at this stage of analysis is to define ambient concentration of the material or its products in areas of concern for receptor (e.g., people, materials or ecosystem components) exposure. A family of computer simulation models has been developed for calculating the ambient levels of a... 

The purpose of Stage 1 is to define the research area, to establish a clear boundary between factors which are to be included and excluded in the analysis.
