The dynamic development of information technologies in medicine of the Krasnodar region, associated with the introduction of modern information systems in healthcare for 2011 - 2014 years has an impact on the system of issuing and servicing preferential recipes and prescriptions for controlled drugs. The introduction of a fundamentally new system of health care based on modern standards, common to the whole territory of the Russian Federation could not be possible to implement without providing healthcare organizations the tools to monitor indicators of prescribing beneficiary drug coverage (BDC) transmitted electronically to pharmacies. In supplying all the participants of the program with the necessary drugs (ND) in the Krasnodar region there is an urgent problem and visualization of information of BDC activities. Improving management by improving the efficiency and reliability of the information for all levels of management in a hierarchical structure of health is directly related to the quality of social services for certain categories of citizens in accordance with the Federal Law issued on July, 17th 1999 178-FZ "On state social assistance." This paper describes a methodology for the creation of a single automated database, which can be placed in both the private secure cloud and in the public, with the possibility of access to information in the workplace using the Internet. Working with a database is implemented by means of language T-SQL. Access to the system of end-users is implemented with taking into account the information security by means of the technology called "thin client". As an application, we use the Services Reporting Services - Reporting server platform that provides opportunities for convenient work with reports of various data sources. The database is filled according to the information of the state health care budget "Medical Information and Analytical Center" of The Ministry of Health of the Krasnodar region.

TECHNOLOGICAL SETUP OF A HOPPER FEEDER FOR PIGS

abstract 1091505041 issue 109 pp. 660 – 675 29.05.2015 ru 1208
Constructive-technological parameters of a hopper feeder have been established. They help to synchronize feeder’s flow and feed consumption by animals. Synchronization of these factors eliminates the initial cause of feed loss during fattening. It was found out that the main influence on feed loss is exerted by shape and geometrical parameters of feedstuff fill at the bottom of feeder, which depend on their physical and mechanical properties and on the feedstuff level in a hopper feeder. The fill balance condition at the bottom of a feeder is provided by compensation of feedstuff weight pressure inside a hopper due to the weight of a surcharge layer. The thickness of layer is proportional to the height of feedstuff volume inside a hopper and does not depend on technological gap between discharging feed line and the bottom of a feeder. It is found out that the discharging feedstuff is distributed throughout the bottom of a feeder. There is a central nonmoving area in the cone shape in alignment with the axis of the discharging feed line. This area functions as a shutter, which reduces the effective area of discharging channel. It is determined that the flow of feedstuff is set by adjusting the technological gap between discharging feed line and its bottom within defined limits. In accordance with physical and mechanical properties of feed this dependence of feedstuff flow allows to determine corresponding functional parameters of discharging feed line in order to meet the needs of a group of fattening animals

MANAGEMENT OF CHOCOLATE MASS STRUCTURE CREATION

abstract 1091505056 issue 109 pp. 824 – 836 29.05.2015 ru 847
In the article the processes of chocolate masses, which are determined by the kinetics of the interaction of the dispersed phase through the layer of the dispersion medium, i.e., determined by surface phenomena at the interface, were examined. The results of the study of surface-active properties of sunflower activated phospholipids and dietary supplements "Vitol", which were performed on the model of structured systems. A theoretical and experimental study of the development of practical recommendations for the use of surface-active substances in the production of chocolate masses is given. The ability of dietary supplements "Vitol" and PAF to control the properties of structured disperse systems, which include chocolate mass, was found out. It is shown that the input of sunflower activated phospholipid and dietary supplements "Vitol" to chocolate masses in certain quantities leads to a significant change in the nature of the deformation behavior of chocolate masses. The behavior of thin layers of cocoa butter, PAF and BAA "Vitol" on various liquid surfaces was introduced. The study was carried out by monolayers. The obtained results showed that increasing the pH of the substrate a surface pressure increases, and the film stretches and tends to spread. It has been shown that the injection of surfactant to cocoa butter film facilitates the spreading of water on cocoa butter. It is found that PAF and especially BAA "Vitol" pose the greatest surface pressure, and the most stable and dense layers comparing to other surfactants. Study of the properties of thin layers of cocoa butter and BAA "Vitol" liquid surfaces showed that dietary supplements "Vitol" significantly increases the ability to spread cocoa butter films on the surface of the water

FORECASTING OF LOSSES OF POWER IN THE POWER SYSTEM OF RUSSIA

abstract 1091505064 issue 109 pp. 938 – 947 29.05.2015 ru 1216
The growth of breakdown in electric networks of Russia has been followed by the growth of industrial and domestic power consumption taking place in our country in the last decade. This situation is directly connected with the high percentage of outdated equipment in electric networks. Such thing as a loss of power is directly connected with deterioration of equipment and breakdown. Average losses of power in the country are at the level of 1980-s, despite the turning point to the side of reduction outlined recently. Forecasting is one of the activities that contribute to their reduction, as it allows identifying adverse trends and calculating the effect of different kinds of technological arrangements. The visible growth of interest in the intellectualization of education and in the different fields of industry should not avoid the electric power field, which is quite conservative. The development of the concept of a “smart network” and its implementation would help to improve the reliability of electric networks. One of the signs of such a network is the possibility to assess the current situation automatically and forecasting of its parameters in the future, including energy losses. This article examines the main factors affecting the value of power losses, the analysis of the most popular methods of forecasting is conducted, and conclusion about the prospects of their use to predict the losses of power has been made based on the results of this analysis

THE ANALYSIS OF THE INFLUENCE OF THE CHARACTERISTICS OF SUSPENSION BRACKET AND TIRES ON LOADING OF WHEELS OF THE CAR WHEN MOVING ON A MULCH BACKGROUND

abstract 1091505067 issue 109 pp. 971 – 980 29.05.2015 ru 1172
The existing settlement modes of loading of wheels of cars are defined for the conditions which are closest to road service conditions and are reflected in the existing standards. However these standards can't be applied to an assessment of functional qualities of systems of cushioning the cars which are operated in the conditions of agricultural production. The small step of roughnesses, change the cushioned characteristics under the influence of operational factors lead to emergence of the off-design modes of the movement. The purpose of the work was the research of loading of wheels of the car when moving on mulch of grains. For the purpose of obtaining characteristics of the roughnesses influencing car wheels we have recorded a smoothed microprofile of the field and got the statistics, rated autocorrelated function, spectral density of influence of a microprofile. For carrying out the researches the known mathematical model of a car road system was accepted. Influence of speed of the movement, normal rigidity of springs and tires, coefficients of damping of a suspension bracket and tires on vertical fluctuations and loading of wheels of forward and back axes of the car is investigated. The executed researches showed that the movement of the car is followed by fluctuations of indicators of loading of running system with obviously expressed periodic components. The change of the coefficient of damping of a passive suspension bracket and tires in possible limits has no essential impact on loading of wheels. Values of normal roughness of springs of forward and back axes of the car, normal rigidity of tires at which dynamic load of wheels of the car is minimum are established

THE STUDY OF THE PROCESS OF SEED DISPERSAL OVER THE PLANT GROWING SURFACE OF A TRAY IN HYDROPONIC SYSTEM

abstract 1091505078 issue 109 pp. 1117 – 1131 29.05.2015 ru 850
The low rate of planting and harvesting mechanization is a common drawback of the equipment for hydroponic green fodder (HGF) cultivation. The system, that has been developed, is represented by a rack construction with a tray positioned on each rack; a tray is the place where the processes of seed dispersal and growth and the takeout of grown HGF occur. A tray with a pipe sways in opposite directions over pipe axis, and, as a result, moving bulk of seeds covers the entire tray surface with a seed layer of uniform thickness. The mathematical model of dynamics in the “granular medium – tray” system has been developed; on the basis of this model, after execution of simulation modeling, practical angles of tray tilt were identified as being within the range of 20 – 30 degrees. Experimental investigations have been carried out on the barley of “Vakula” cultivar with seed moisture contents 10%, 14%, 16% and 18%. During the research, the main factors influencing the process under consideration were identified: the moisture content in barley seeds; initial angle of tray tilt; the number of tray swaying motions. It was determined that the increase of tray filling rate can be achieved by means of setting up the initial angle of its tilt from a reference level, which depends on the moisture content in the barley seeds used in the process of HGF production. This angle is 22 – 24 degrees for the dry barley seed with moisture content 10-14% and 25 – 27degrees for the barley seed with higher moisture content. The upper limit of moisture content in the seeds used in work process should be specified to achieve high quality of a final product. The barley seeds with moisture content 10-15% and the angles of tray tilt 23 – 25 degrees should be used during HGF production
