Species of Fungi in the Root System of Woody Plants in Urban Plantations
The features of the species composition of microscopic fungi in the root system and rhizosphere soil of woody plants in connection with the level of soil contamination have not been studied sufficiently. This article presents the results of studying the species composition of fungi in the root system and soil of three species of woodyplants (Acer negundo L., Acer platanoides L., and Betula pendula Roth.) growing in urban plantations of various ecological categories with different levels of heavy metal soil contamination. The study was carried out in a large industrial center of the Urals region, Izhevsk. When studying the species composition of fungi, microscopyand molecular genetic analysis were used. Isolates of endotrophic fungi from the root system of plants were isolated, and systematic membership was determined by molecular genetic analysis. The results showed that in soils with a high level of contamination, the DNA of endotrophic mycorrhiza-forming fungi was found in theroots of woody plants in a good living state.

Развитие концепции биструктурного анализа для повышения эффективности управления
This article speaks about development of bistructurniy analys, which lets manager find concrete reason for inward conflict of worker, discover constructive withdrawal from this situation in behalf of organization, design for own interests of worker and draw a conclusions, which must be conducive to effective being at the head of worker in future on the basis of principle individual approach to each worker. The development this conception includes new hypothesis about reason constructive or destructive behavior of worker.В статье выдвигается гипотеза о причинах конструктивного или деструктивного поведения работника, которая позволяет менеджеру выявить причину внутриличностного конфликта работника, конструктивно разрешить данный конфликт в интересах организации с учетом потребностей самого работника и сделать выводы, которые должны способствовать эффективному управлению работником в перспективе на основе принципа индивидуального подхода к работнику

One of the main criteria for health is still a rate of a, which in civilization’s countries is constantly decreasing, which causes the lengthening of life.However, along with this significantly changes the structure of morbidity: reduction of infectious diseases accompanied by increased infectious. All of these diseases can be divided into professional and vocational-conditioned. Key words: health, disease, occupational diseases, professional diseases due to
Eritrocytic Parameters of the Blood of Calves with Different Birth Weights
In the conditions of a dairy farm with the help of the standard clinical, instrumental and laboratory methods the research on particularities of Eritrocytic parameters of the blood of calves (n=299) with different birth weights was carried out. It is shown that Holstein calves with normal intrauterine growth, born with body weight from 36.5 to 29 kg, have no reliable differences in red blood cell count. With a 1 kg reduction in body weight, there is a trend towards hyperchromia, but an increase in weight deficiency promotes of hypovolemia, hypochromia, and polycythaemia. In newborns with a body weight of 27.9–26.9 kg, polycythaemia is derived from hypovolemia, but, with a more pronounced weight deficiency, the role of erythrogenesis disorder in the pathogenesis of the syndrome increases. Hypochromia is a consequence of hematopoietic organs dysfunction and transmembrane loss of hemoglobin. Herein membrane destruction is caused by the increase in the content of toxical metabolites in the blood (sorptivity of red blood cells by 10–12 percent), and by a higher level of adrenaline (modification coefficient of membranes by adrenaline by 20–30 %). This indicates that the response of the fetus to the factors that inhibit its development is similar to a metabolic response against stress. At strong underweight body (b.w. less than 25 kg) exhausting of adaptive capability is observed with the increase in the blood level of toxical metabolites (sorptivity of red blood cells by 15 %), level of membrane destruction (level of ectoglobular hemoglobin in 2,8 times), and heterogeneity of red blood cells. Thus, in newborns with a body weight of less than 29 kg, the significant disturbances in the structure and functions of red blood cells were revealed, which gave grounds for stating that they had antenatal hypotrophy. Herewith, the severity of hematological changes depends on the degree of weight deficiency. Initially, it is hypovolemia and the resulting polycythemia, but, erythropoiesis disorders, and destruction of their membranes with increased polycythemia, and the development of hypochromia occur with the increasing severity of hypotrophy
