Aim. The aim of the study was to study the frequency of occurrence of exposure to harmful occupational factors in patients with sarcoidosis of the respiratory organs, depending on the course of the disease. Materials and methods. An open prospective study included 121 patients with sarcoidosis of the respiratory system from the age of 21 to 66 years, from 20072019. The diagnosis was histologically confirmed in all patients. Patients underwent a set of laboratory and instrumental examinations, studied profane history. The presence of a history of contact with harmful and dangerous production factors was clarified. To determine the effect of a harmful production factor on the course of sarcoidosis, patients were divided into 2 clinical groups: the first group consisted of 85 (70.2%) patients with a favorable course of the disease, the second group included 36 (29.8%) patients with an unfavorable course sarcoidosis (standardization coefficient between groups 2.4:1). Results and discussion. Among the examined patients of working age prevailed (87%). Patient groups were comparable by age, but statistically differed by gender (chi2=9.75, p=0.0018). Frequency analysis of the occurrence of harmful occupational factors in sarcoidosis of the respiratory organs showed that the most frequently encountered factors in all the studied groups were contact with chemical hazards. Conclusion. The presence of contact with harmful production factors increases the risk of an unfavorable course of sarcoidosis by more than 2 times.

Introduction. One of the priority socio-economic and medical-demographic problems in Russia is the high mortality. The study aim is to identify the most significant factors that determine the mortality on the example of two single-industry towns. Materials and methods. Mortality in two single-industry towns specializing in copper-nickel production, differenced in climate, environmental, and socio-economic indicators, was studied using age-standardized indicators averaged over 8 years (2010-2017). Results. In Monchegorsk, compared to Russia, with similar non-production characteristics, working-age mortality from cardiovascular diseases (CVD) was higher by 49.0%, from malignant neoplasms (MN) by 34.7%, from diseases of the digestive system by 35.5%, which confirms the negative impact of occupational factors on the mortality of the population of a single-industry city. In Norilsk city, with the worst characteristics of the environment and climate, compared to Monchegorsk, mortality from CVD was lower in working age by 40.6%, in post-working age by 41.4%; from MN - in working age lower by 37.2% that shows the compensating influence of socio-economic factors on mortality. Conclusion. Risk factors for increased mortality rates in single-industry towns with copper-nickel enterprises are the influence of harmful occupational factors, as well as environmental pollution. Along with primary prevention, an effective mechanism for reducing mortality is to improve socio-economic well-being, and the quality of medical care.

The article presents the results of the analysis of health, working conditions and prevalence of adverse production factors, the structure of the detected occupational pathology in the working population of the Russian Federation. The article presents Statistical data on the dynamics of the share of workplaces of industrial enterprises that do not meet hygienic standards, occupational morbidity in 2015-2018 for the main groups of adverse factors of the production environment and the labor process. The indicators of occupational morbidity over the past 6 years in the context of the main types of economic activity, individual subjects of the Russian Federation, classes of working conditions, levels of specialized occupational health care. The role of the research Institute of occupational pathology and occupational pathology centers in solving organizational, methodological and practical tasks for the detection, treatment, rehabilitation and prevention of occupational diseases is shown. The basic directions of activity in the field of preservation and strengthening of health of workers, and also safety at a workplace are defined.

Processes of the expected spatial socio-economic changes arise as a result of rational planning and continuation of development at regional and local level. A three-tier division ofthe local self-government creates opportunities for engagement of community in the rational planning model and local resource management, as well as usage of production factors; for socio-economic growth and improvement in the quality of life of the residents. The aim of the article is to show the functional structure and role of local government units in formation of regional and local policy toincrease economic growth, while maintaining the environmental protection requirements.

Laminated Materials

Laminated materials incorporating plastics seem to be especially well suited lor highly stressed aircraft components, by reason of their good strength properties. Paper, fabric and wood veneers treated with plastics on a phenolic basis were tested with regard to their strength, especially in bending, shear, absorbed energy in impact bending, notching strength and in their resistance against moisture. Further, the behaviour of compressed plastics was studied at different temperatures under static and dynamic loads. A part of the research was extended to pure phenol resin and to thermoplastics based on methacrylate and polyvinylchloride. The bonding properties of laminated compressed plastics were established. Concluding, some experiments relating to the practical manufacture of aeroplane components are communicated.

ABSTRACTA recent consideration in aircraft design is the use of folding wing-tips with the aim of enabling higher aspect ratio aircraft with less induced drag while also meeting airport gate limitations. This study investigates the effect of exploiting folding wing-tips in flight as a device to reduce both static and dynamic loads. A representative civil jet aircraft aeroelastic model was used to explore the effect of introducing a wing-tip device, connected to the wings with an elastic hinge, on the load behaviour. For the dynamic cases, vertical discrete gusts and continuous turbulence were considered. The effects of hinge orientation, stiffness, damping and wing-tip weight on the static and dynamic response were investigated. It was found that significant reductions in both the static and dynamic loads were possible. For the case considered, a 25% increase in span using folding wing-tips resulted in almost no increase in loads.

Tubular Billet

Bellows are a cylindrical shell with a corrugated part, widely used in aviation engineering as a movable sealing element to balance pressure and temperature differences, which ensure continuous and accurate system operation. The use of bellows expansion joints provides reliable and effective protection of pipelines from static and dynamic loads arising from deformations and vibration. Welded-edge bellows are a popular choice for regulating and controlling fuel supply in aircraft devices. The ability of the compensator to perceive deformations is determined by its assigned operating time, which describes how many cycles, and with what amplitude, the bellows compensator perceives without damage. A method for stamping bellows from tubular billets by using magnetic-pulse field in rigid dies, including sequential shaping of corrugations by distributing the internal magnetic pressure with axial movement of the free end of a tubular billet, characterized in that the material of the tubular billet for shaping corrugations is selected in accordance with its relative elongation.
