Study of certain features of the electronic structure of the ternary alloys Ni2(Mn, Fe) and Ni3(Mn, Co)

The changes in electronic structure related to transport processes occurring during the alloying of he alloy Ni3Mn with iron and cobalt, and the ordering of the ternary alloys thus formed are presented. The Hall effect, the absolute thermal emf, the internal saturation induction, the Nernst-Ettingshausen constant, and the electrical resistivity were measured. Results show a decrease in the contribution of hole sections of the Fermi surface to the transport process occurs together with a considerable increase in the contribution of electron sections. In this case, the mobility of 3 dimensional holes decreases and the mobility of 4s electrons increases considerably

Ecological consequences of the playgrounds' reconstruction of specialized "park-stadium Khimmash", in Yekaterinburg

In connection with the World Cup in 2018 in the Russian Federation, including the qualifying matches of the World Championship in Yekaterinburg, the Government of the Sverdlovsk Regiondecided to place a training ground on the territory of the "Park-stadium Khimmash". For this purpose, a sports field reconstruction project was created and implemented. The article is devoted to the assessment of negative consequences for plantings of the "Park-stadium Khimmash" in Yekaterinburg as a result of the construction, which led to the destruction of 388 trees, 95 of them are pine trees. The park historically originated on the site of a natural pine plantation. Cutting down so many trees led to further disintegration of the stand. According to the project, the replacement of felled large park trees of pine and birch by willow and apple trees is recommended, which led to the destruction of natural landscapes that have survived in the urban environment. At the same time, not only the aesthetic perception is worsened, but the ecological criteria of the industrial area of the city are also reduced. First of all, the oxygen-producing possibilities of the plantation decreased, which is reflected in the economic assessment of the consequences. © 2019 IOP Publishing Ltd. All rights reserved

Development of an oximeter for neurology

Cerebral desaturation can occur during surgery manipulation, whereas otherparameters vary insignificantly. Prolonged intervals of cerebral anoxia can cause seriousdamage to the nervous system. Commonly used method for measurement of cerebral bloodflow uses invasive catheters. Other techniques include single photon emission computedtomography (SPECT), positron emission tomography (PET), magnetic resonance imaging(MRI). Tomographic methods frequently use isotope administration, that may result inanaphylactic reactions to contrast media and associated nerve diseases. Moreover, the high costand the need for continuous monitoring make it difficult to apply these techniques in clinicalpractice. Cerebral oximetry is a method for measuring oxygen saturation using infraredspectrometry. Moreover reflection pulse oximetry can detect sudden changes in sympathetictone. For this purpose the reflectance pulse oximeter for use in neurology is developed.Reflectance oximeter has a definite advantage as it can be used to measure oxygen saturation inany part of the body. Preliminary results indicate that the device has a good resolution and highreliability. Modern applied schematics have improved device characteristics compared withexisting ones

THE WAYS OF OPTIMIZATION OF COSTS HOTEL COMPANIES IN A CRISIS

The article considers various ways of saving hotel costs in crisis conditions, namely: reduction of expenses on advertising, marketing, participation in exhibitions, reduction of the list of additional services, the failure of customers from a range of services, which reduces cost, optimization of expenses for staff salaries, the sustainable use of water, electricity, heating in hotels and flexible pricing, aimed at maximizing a hotel

Theoretical and Methodical aspects of organizational competitive advantages’ management

The paper deals with the features of competitive advantages as an object of management. The comparative analysis of main approaches to creating competitive advantages is carried out, which allows the authors to conclude that it is necessary to integrate existing approaches. The paper also substantiates the feasibility of using stakeholder analysis and scenario approach in the process of managing competitive advantages. The authors offer a basic scheme for managing competitive advantages, show the interconnection of different approaches and their contribution to creating sustainable competitive advantages

PERSONNEL POLICY OF HOTEL COMPANIES DURING THE CRISIS

Considered and analyzed possible scenarios of functioning hotels during the crisis shows the features of the implementation of the personnel policy of the hotel, depending on the scenario of development of hotel business. Proposed a number of measures to effectively overcome the hotel companies of the crisis in the field of human resources policy, namely the definition of the feasibility of increasing / reducing the personnel, of the availability in a hotel of low value and valuable employees, the formation of the list of methods and means of motivating highly skilled and valuable for the employees of the hotel, carrying on the formation of work management reserve of its own personnel or to attract from professionals
