[Growth of microfungi on the external polyethylene anticorrosive coating of oil-gas pipes].

The authors have studied the resistance of external anticorrosive polyethylene coat of oil-gas pipes (based on the high-density polyethylene, HDPE) to the action of microfungi, natural contamination, fungistatic and fungicide activity. It was found that the intensity of growth of standard test cultures on the surface of polyethylene coat increases in terms which imitate mineral and organic contaminations, and this results in the decrease of the index of its resistance to the action of microfungi. The microfungi, found in the process of study of natural contamination of polyethylene coat and its components, are presented by six species, Alternaria sp.

[Identification of the groups of miners requiring ambulatory care using personal computers].

When carrying on miners' follow-up, the results of the assessment of their health state on the basis of the data on the anamnesis, objective examination, morbidity and sanitary and hygienic labor conditions should be taken into account. The analysis of these data is associated with significant time losses of a physician or a group of physicians and does not guarantee against errors in the determination of medical supervision groups of miners. There is suggested an improved logical scheme of data analysis, providing exact determination of medical supervision groups with minimal time losses.

[Logico-semantic modeling of the structure of the hardware and software of medico-biological measurements].

An optimal correlation between the development tendencies, the popular use of reliable, practically checked technical novelties, the creation and mastering of principally new types of technique and technology is of great value in the development of science and technology programme. This task is solved by logico-semantic modelling. The prospects of the stated approach are conditioned by the possibilities of automatization of the purpose-supposing approach, that during the elaboration of medical scientific and technical programmes leads to reduction of expenditures for carrying out this function, allows to raise the demands for structure and order of program realisation, removes the duplication of search operations and information transmission in the preparatory period, that finally reduces the elaboration time and increases the quality of scientific and technical programme, provides complex approach to medical information problems.
