METHODOLOGICAL APPROACHES TO THE ESTIMATION OF INDIVIDUAL OCCUPATIONAL RISK TAKING INTO ACCOUNT INDICATORS OF LIFE QUALITY

Authors offer to make changes to technique of the estimation of life quality with three blocks of professional and nonprofessional risk factors: index of observance of requirements of sanitary legislations; index of way of life and index of social well-being. The index of observance of requirements of sanitary legislations pays off by result of an expert estimation of a workplace taking into account aggravating (absence of certification of workplaces, industrial inspection; insufficiency of the area and volume of premises; absence of ventilation, repairs, work and rest modes; neediness of good-quality potable water, sanitary-household premises, first-aid sets of the first medical aid; absence of system of informing of workers about an existing professional risk and ways of its decrease etc.) and normalizing factors (presence of complexes intrareplaceable and after a labor shift medical rehabilitations etc.). The index of way of life is offered to be counted taking into account major individual behavioral and biological factors of risk of death rate and invalidity in Russia: smoking, abusing alcohol, irrational food (in particular, the uses less than 400 g vegetables and fruit in day), insufficient physical activity, raised index of weight of a body, psychoemotional stress, raised levels of cholesterol and glucose in whey of blood, arterial pressure, burdened heredity. The index of social well-being pays off as the one-numerical indicator considering social and economic and socially-psychological factors: indicator of size of wages, indicator of satisfaction health, working conditions, work as a whole, life as a whole, an indicator of the individual importance of factors of psychological overload. Authors of article suggest to add an existing technique of an estimation of an indicator of the individual importance of psychological overload factors with indicators actual in modern industrial conditions: socially-psychological adaptation, degree of emotional burning out, quality of life. The estimation of quality of life can serve in this system to one of the most significant after experience medical and biologic criteria of an estimation of an individual professional risk

ON THE PROBLEM OF AEROGENIC FACTORS OF OCCUPATIONAL RISK FACTORS AND DIAGNOSIS BAUXITE PNEUMOCONIOSIS

Item. 4.2.2.6 "bauxite pneumotoxicosis (influence of bauxite dust)" is included, in the "List of occupational diseases" (code Х J 63.1), that requires elaboration of standards of its diagnostics, treatment and rehabilitation of patients. The article presents the results of clinicohygienic researches of the evaluation of influence of bauxite dust on the condition of bronchopulmonary system of the employees. It was shown than influence of low-fibrinogenous dust at the extraction of bauxite ore leads to the development of pneumotoxicosis, that shows itself as significant convection and. hemodynamic disorders that limit patients' earning capacity

Off-shell superconformal nonlinear sigma-models in three dimensions

We develop superspace techniques to construct general off-shell N=1,2,3,4 superconformal sigma-models in three space-time dimensions. The most general N=3 and N=4 superconformal sigma-models are constructed in terms of N=2 chiral superfields. Several superspace proofs of the folklore statement that N=3 supersymmetry implies N=4 are presented both in the on-shell and off-shell settings. We also elaborate on (super)twistor realisations for (super)manifolds on which the three-dimensional N-extended superconformal groups act transitively and which include Minkowski space as a subspace.Comment: 67 pages; V2: typos corrected, one reference added, version to appear on JHE

The ultra-violet question in maximally supersymmetric field theories

We discuss various approaches to the problem of determining which supersymmetric invariants are permitted as counterterms in maximally supersymmetric super Yang--Mills and supergravity theories in various dimensions. We review the superspace non-renormalisation theorems based on conventional, light-cone, harmonic and certain non-Lorentz covariant superspaces, and we write down explicitly the relevant invariants. While the first two types of superspace admit the possibility of one-half BPS counterterms, of the form $F^4$ and $R^4$ respectively, the last two do not. This suggests that UV divergences begin with one-quarter BPS counterterms, i.e. $d^2 F^4$ and $d^4 R^4$, and this is supported by an entirely different approach based on algebraic renormalisation. The algebraic formalism is discussed for non-renormalisable theories and it is shown how the allowable supersymmetric counterterms can be determined via cohomological methods. These results are in agreement with all the explicit computations that have been carried out to date. In particular, they suggest that maximal supergravity is likely to diverge at four loops in D=5 and at five loops in D=4, unless other infinity suppression mechanisms not involving supersymmetry or gauge invariance are at work.Comment: 56 pages, 1 figure, uses youngtab.sty.
