Aim. To cоmpare the results оf infra-spinal reconstructions of the lower extremities with the formatiоn of a distal anastomоsis below the knee joint fissure with the use of a bioprosthesis and autovein in critical limb ischemia (CLI).Methods. The hospital results of revascularization were retrospectively analyzed in 53 patients with CLI who underwent primary prosthetics of the femoral-popliteal segment with the fоrmation of a distal anastomоsis belоw the knee joint gap. All patients, depending on the prоsthetic material used, were divided into two groups: 1) autovein was used as a prosthesis (39.6%, n = 21)) and 2) a bioprosthesis was used (“KemAngioprosthesis” closed joint-stock company “NeoCor” Kemerovo, Russia) (60.4%, n = 32).Results. In the early postoperative period, thrombosis developed in group 1 in 7 cases (33.3%): in 5 patients – on the first day after the surgery; 2 out of 5 patients were with chronic arterial insufficiency (CAI) of the fourth degree, 1 was with acute arterial insufficiency of the first degree, and 2 patients with the third degree of CAI. In group 2, there were 6 prosthetic thrombosis (18.7%), 4 cases of which developed thrombosis on the first day, 3 patients with CAI of the fourth degree and 1 case with acute arterial insufficiency of the second degree.Conclusion. The application of infra-lingual reconstructions using bioprostheses is quite effective and safe in patients with CLI, in particular with purulent-necrotic trophic processes when a suitable autovein to be used as a prosthetic material is absent.

Corporate Legislation

The article analyzes legal aspects of institutes of corporate governance. Different draft laws "On Joint-Stock Companies" are considered which reflected interests of separate groups of participants of market relations. Stages of property redistribution are outlined. The advantages of the model of the open joint-stock company are formulated. Special attention is paid to the demand for legal institutes of corporate governance as well as to the process of accepting the Federal Law "On Entering Amendments to the Federal Law "On Joint-Stock Companies"" which was enacted in 2002. The article contains proposals directed at improvement of corporate legislation.

The aim of the study was to assess the professional risk of developing diseases in workers of the railway car repair enterprise. The Voronezh Car Repair Plant, a branch of Vagonremmash Joint-Stock Company, was chosen as the object of study. Methods: «The methodology for calculating individual occupational risk depending on the working conditions and the health status of the employee», developed by the Klin Institute for Protection and Working Conditions in conjunction with the Research Institute of Occupational Medicine (2013), the main professions; cohort study with the calculation of the relative risk of morbidity with temporary disability, the odds ratio, the etiological share of factors in the formation of morbidity (group size: 250 people, experimental group — workers of the main specialties, 95 people — comparison group). Results. According to the research results, the priority factors of occupational health risk include: chemical, noise, heating microclimate, low light level. For certain professions, the share of the contribution of priority factors to the risk profile (PV) reaches 40 %. The indicator of individual occupational risk is 0.12 to 0.26 units. The high level of professional risk (0.22 ÷ 0.26) is characterized by the working conditions of the mechanics for the repair of rolling stock, machine tools (woodworking), casters (metal), thermists, plastic casters. In professional groups with medium and high risk, the indicator of the relative risk of morbidity with temporary disability is higher than 1 (RR = 1.75 and 1.39, respectively), and the etiological share of production factors in the formation of diseases is from 27.95 (subgroup with secondary professional risk) up to 42.88 % (a subgroup with high professional risk), which indicates the professional condition of the disease. Discussion. In general, our data are consistent with the results of similar studies conducted earlier at the car building and car repair enterprises. In order to ensure hygienically safe working conditions and preserve the health of workers, it is necessary to reduce the level of exposure to production factors, including through the introduction of modern equipment and improvement of technological processes.

The article studies the financial stability of a particular insurance organization. The financial stability of the insurance company is an essential component of its activities and characterizes the ability to pay off its obligations on time and in full. The analysis of financial stability is defined as an independent object of evaluation, which explores the structure of the formation and use of capital. To assess the financial stability of the insurance company, a set of indicators was formed, including the following ratios: level of equity, ratio of equity to liabilities, ratio of insurance premiums and insurance reserves, ratio of working capital and non-current capital, level of permanent capital, ratio of equity and insurance reserves, level of debt load, level of insurance reserves. The insurance public joint-stock company RESO-Garantia was chosen as the object of analysis. The analysis showed that the capital structure in the insurance company under consideration is not optimal. The company has a shortage of insurance reserves, which is offset by equity.

The Impact

Recently, the development of agricultural technology has been focused on achieving higher reliability and quality of work. The aim of the presented paper was to examine the possibilities of evaluating the quality of work of wide-area irrigation machinery by monitoring the coefficients of uniformity and non-uniformity of irrigation. The object of the research was pivot irrigation machinery equipped with sprinklers with a total length from 230 to 540 m. The commonly applied quality of work parameter for wide-range irrigators is the irrigation uniformity coefficient according to Heermann and Hein CUH. Work quality evaluations were also carried out through other parameters applicable in practice, such as irrigation uniformity coefficients calculated according to Christiansen CU, Wilcox and Swailes Cws, and our introduced parameters, the coefficient ar (derived from the degree of unevenness according to Oehler) and the degree of uniformity γr (derived from the degree of non-uniformity according to Voight). Other applied parameters for determining the quality of work of wide-range irrigation machinery were the coefficients of irrigation uniformity according to Hart and Reynolds CUhr, further according to Criddle CUcr and subsequently according to Beale and Howell CUbr. Next, the parameters of the non-uniformity coefficient according to Oehler a, the coefficient of variation according to Stefanelli Cv, the degree of non-uniformity according to Voigt γ and the degree of non-uniformity according to Hofmeister Ef were evaluated. Field tests were performed during the growing season of cultivated crops (potatoes, corn and sugar beet) in the village of Trakovice (agricultural enterprise SLOV-MART, southwest of the Slovakia) and in the district of Piešťany (Agrobiop, joint stock company). During the research, the inlet operating parameters (speed stage, inlet pressure, irrigation dose), technical parameters (number of sprayers, total length, number of chassis) and weather conditions (wind speed and temperature) were recorded. The obtained results were examined by one-way ANOVA analysis depending on the observed coefficient or input conditions and subsequently verified by Tukey and Duncan tests as needed. Irrigation uniformity values ranged from 67.58% (Cws) to 95.88% (CUbh) depending on the input conditions. Irrigation non-uniformity values ranged from 8.58 (a, Ef) to 32.42% (Cv). The results indicate a statistically significant effect of the site of interest and thus the impact of particular field conditions (p < 0.05). When evaluating the application of different coefficients of irrigation uniformity, the results showed a statistically significant effect only in the first test (p = 0.03, p < 0.05). During further repeated measurements, the quality of work increased due to the performed inspection of all sprayers and the reduction in the influence of the wind.
