INFLUENCE OF HILLY TERRAIN SLOPE ON THE VOLUME OF ROAD EARTHWORK
DescriptionThe analytic dependence for slope correction calculation is obtained. This correction is introduced in the formula for calculating the area of earth roadbed cross-section. It allows detailing the volume of road earthwork at the design stage. The correction size depends on the slope steepness as well as cross-sectional parameters of the earth roadbed. The calculations show that the correction size is essential if ratio of slope is 25 or less

WAYS OF STABILIZATION THE ENERGY OF SMALL HYDROPOWER PLANTS
DescriptionThe article deals with the basic methods of stabilizing voltage generators for small hydroelectric power plants. It shows a block diagram of the implementation and analysis of the characteristics of the work; it reveals the advantages and disadvantages. The authors explain the features of the work of the functional circuits voltage regulators with discrete ballast, with phase control and management of the load current. It is shown, that to improve the performance of small hydroelectric power plants considerably we have to use contactless generators in their construction: asynchronous generators with capacitive excitation and synchronous generators with permanent magnets. The functional scheme of the voltage regulator, the construction of which has an additional field winding, simplifies the system voltage stabilization of the synchronous generator with permanent magnets, as well as a functional scheme of an asynchronous generator voltage regulator, made using step-up transformers, which significantly reduces the weight of the capacitors providing excitation of the generator and compensation of reactive power load. We have discussed the methods and devices for stabilization of voltage generators which will improve the effectiveness of pre-design work on the creation of new devices of stabilization of parameters of electric power generators for small hydroelectric power plants with improved operational and technical specifications

REGULARITIES OF DEFLECTION IN THE DIAGONAL AND RADIAL TIRES OF THE GRAIN COMBINE PROPULSIONS
DescriptionThe aim of the study is to investigate the regularities of deflection in the diagonal and radial tires for the grain combine propulsions of high productivity. The research method is experimental. The "tire tester" and specially designed devices for revealing the deflections of the inner and outer tube relative to the rim in the circumferential and radial directions have been used. The outcome indices of the pneumatic-tired wheel are determined with the tire capability to deflect so, that at low - hysteresis losses in the rubber-cord casing and its acceptable tensions, based on a resource, the largest area of contact with supporting base would be created. This circumstance acquires the particular significance developing tires for grain combines of high performance, the deflection regularities of which are poorly studied at present. The analysis of experimental studies showed the feasibility of using the grain combine propulsions instead of the diagonal radial tires of the same size. The resistance to rolling of radial tires 30.5 R-32 is lower than in diagonal tires 30.5 L-32, and the developed contact area due to the increase of length is higher, which reduces sealing effect on the soil

Description
The article is devoted to the gradual development of an information system for automated distribution of applications, the development of the necessary organizational diagrams, decomposition charts, as well as constraints the design stage. With the help of a program complex, the request from the client is submitted to the Deputy Director for production, which makes the decision about treatment (accepts or cancels the request). Also via software package, the application is sent to the Deputy Director for the status of implementation, as well as the Director, the chief accountant and the client. Each Department has the ability to contact the Deputy Director for operations for the consultation when a problem occurs with the implementation of the application. After obtaining the status of completed applications in the software package, the chief accountant reports to the Director. A set of methods and techniques of organization of information processes in production systems which allow the selection and the use of an information technology solution for the synthesis of knowledge about the work situation is the content of the concept of formation of information resource management for system knowledge-intensive production. Management system information space manufacturing organizations are formed in a specific environment, which is characterized as an information resource management system – a system of organization of internal and external flows of information, as well as methods and tools for searching, processing and distribution of information in the organization

Description
The article presents a comparative assessment and peculiarities of nuclear magnetic relaxation characteristics of rapeseed and sunflower lecithin. It was established, that lecithin’s nuclear magnetic relaxation characteristics, namely, protons’ spin-spin relaxation time and amplitudes of nuclear magnetic relaxation signals of lecithin components, depend on content of oil’s fat acids and phospholipids, contained in the lecithin. Comparative assessment of protons’ spin-spin relaxation time of rapeseed and sunflower lecithin components showed, that for their identification protons’ spin-spin relaxation time of the lecithin’ first component at 40°C and 60°C temperature, when differences in values of protons’ spin-spin relaxation time of the sunflower and rapeseed lecithin’ first component are most obvious, should be used as an analytical parameter. Comparative assessment of amplitudes of proton’s NMR signals of sunflower and rapeseed lecithin components showed, that relations, established earlier for sunflower lecithin between mass share of phospholipids (substances insoluble in acetone) and the sum of amplitudes of proton’s NMR signals of the third and fourth components, cannot be applied to rapeseed lecithin; that is for the development of an express method for determination of mass share of substances insoluble in acetone (phospholipids) in rapeseed lecithin, it is necessary to carry out additional research with the purpose of clarifying the mentioned relations
