SIMULATION OF THE SPRINKLING PROCESS WITH THE MACHINES OF FRONT ACTION WITH SECTOR NOZZLES
DescriptionThe article deals with the methods of mathematical simulation of water distribution processes by the machine of unbroken front moving with deflector nozzles of sector influence. Mathematical simulation using lets choose the optimum labor and money expenditure. The nozzles work under low pressures, it results in power inputs reduction of liquid distribution process about the field along with more regular water distribution. The coefficient of water doze variation 1,71% under 7 m distance between the nozzles is got in the circulation example

TO THE PROOF OF THE NONDEMOUNTABLE METHOD OF REPAIR OF THE HIGH PRESSURE FUEL PUMP
DescriptionThis article discusses the application of the method of selective transfer to restore the plunger pairs of high pressure fuel pumps of diesel engines. To restore plunger pairs the authors of the article propose to use an anti-friction repair-and-renewal composition on the basis of the mineral serpentinite

Description
We have made energy estimation of absorbed solar fluxes with a glance of diffuse insolation which passes through double- glazing unit to the right-angled planar radiator. While designing the model it was conceded to assume that direct solar radiation is the radiation of a point source

A COMPUTER MODEL OF THE CONSEQUENCES OF AIR-FUEL MIXTURE EMERGENCY EXPLOSIONS
DescriptionIn this article the basic principles of air-fuel mixture explosions and striking factors, such as air-striking wave, gas streams, splinters, flame heat, light radiation and sharp sounds are observed. The calculation technique of the emergency emission consequences which is for a quantitative estimation of air-striking wave parameters at air-fuel mixture explosions forming in the atmosphere at industrial failures is given. The basic structural elements of calculation algorithm are listed. It is supposed partial depressurization or full destruction of the equipment containing combustible substance in a gaseous or liquid phase, the emission of this substance in the atmosphere, the air-fuel mixture cloud formation, the air-fuel mixture initiation (ignition) and the explosive transformation (deflagration or detonation) in the air-fuel mixture cloud. The technique allows making the approached estimation of air-striking wave various parameters and defining the probable degrees of men defeat and building damage at failures with air-fuel mixture cloud explosions. The given technique is developed in C# language in the integrated environment of software Microsoft VisualStudio 2010 working out. The program fragment in which the calculation of dimensionless Px pressure and dimensionless Ix impulse is given

06.00.00 Agricultural sciences
DescriptionThe process of the presowing seed treatment with alternating electromagnet field of the commercial frequency (EMF CF) 50 Hz is economically efficient. The use of the EMF CF 50 Hz in the unit with ring pole pieces allows increasing the germinating energy and power. The electromagnet seed treatment in the units with ring pole pieces is the perspective process of the presowing treatment which does not make unhealthy influence on the operating personnel. At the presowing treatment we have to take into account three factors, they are the arrangement of seeds in the working chamber, the time of treatment and the seed humidity. In this article the authors recommend to promote the unit consisting of a magnetic circuit with ring pole pieces of the rectangular cross-section, a magnetizing coil and an embedding of the non-magnetic material in the working chamber which allows increasing the germinating energy of spring barley by 10% and the germination by 7%. As field experiences have shown the highest seed germination and good crop capacity take place in the work chamber zone with boundaries R1=0,012 m and R2=0,035 m at seed humidity from 12% till 18% and the time of seed treatment is 0,9-2,75 s. The addition to crop capacity has run to 7% as a result of the spring barley treatment
