DescriptionThe use of physical factors for preplant stimulation of seeds increases vigor, germination and improves the yield of agricultural products. One of the effective ways to improve seed grain quality is to impact on the seeds using physical factors, in particular, an alternating electromagnetic field of industrial frequency of 50 Hz (EMF of IF of 50 Hz). We studied the impact of EMF of IF of 50 Hz on the energy germination of mid-ripening spring barley seeds of promising varieties Vakula, Vikont, Ratnik. Carrying out the experimental studies we used a laboratory setup with annular pole points of rectangular cross section. Our disperse analysis resulted in data on germinative energy of seeds of spring barley varieties Vakula, Vikont, Ratnik, which showed that while treating seeds of spring barley by an alternating electromagnetic field of industrial frequency of 50Hz, we obtained the best values of germinative energy of seeds of Variety Vikont with a mode of processing being equal to W = 16%, T = 2 c, L = 0,03 m

06.00.00 Agricultural sciences
DescriptionDuring 2012-2015 from the two fissile populations of rice hybrid Il.14 x Kuboyar and Il.28 x Kuboya we conducted multidirectional selection of panicles with low, medium and high number of grains in them. It was established a different reaction to the selection of hybrid generations by yield. The lowest yield was formed at planting grain from small panicles, intermediate - from the middle panicles and biggest - from the major panicles. The reaction to selection decreased with each successive generation. In the hybrid Il.14 x Kuboyar at positive selection of the yield increase towards the initial population F2 was in F3 - 10,5%, in the F4 - 3,8% and F5 - 1,9%, at Il.28 x Kuboyar - respectively 4, 4%, 3.1% and 0.7%. At negative selection in Il.14 x Kuboyar there was a decrease of yield on 7.7% F3, in F4 on 6.9% and in F5 on 0.2%. By years of research was not observed variations in grain yield obtained from the panicle with an average grainness and generally was at the level of the original population. At the hybrid Il.28 x Kuboyar for negative selection of the relative yield initially decreased on 1.7% in F3, while then for all kinds of selection to the fifth generation grew up and different to a lesser extent than the first the hybrid, although the ranks of the values preserved. The yield from a fraction of well-grained was 98.4%, medium grained - 96.5%, low grained - 94.2% of the initial Kuboyar variety

Description
In the article, we have described the main causes of the fuel-air mixtures explosion and such affecting factors as air blast and fragmental fields. Explosions are performed using various sources of energy. The scale of the explosions consequences depends on their detonation power and the environment in which they occur. The range of the affected areas can reach several kilometers. The basic parameter that characterizes the explosives is the maximum pressure. Increasing distance from the explosion, the maximum pressure and pulse decrease and action duration increases. There is presented method, which is developed in Windows-based applications that allows investigate the dependence of the destruction level on the distance and the explosion epicenter. Algorithm of application operation implements automatically filling of the "molar mass of combustible material, g/mol" field depending on the user’s choice of the flammable substance name. After calculating the raw data, the user moves to the calculation of all the parameters and sees the results of the calculation. By default, the calculation results are presented in tabular form. Further, the results of calculation are presented with a graphical representation of data. The developed software can be used in the educational process at studying such disciplines as "Theory of burning and explosion", "The production safety", "Protection in emergency situations", and also be recommended to practical workers in the sphere of labor safety, prediction and assessment of the technological accidents and catastrophes consequences, teachers of this profile disciplines

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 one has 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 nonmagnetic material in the working chamber which allows to increase the germinating energy of spring barley by 10% and the germination by 6,5%. The addition to crop capacity has run to 7% as a result of the spring barley treatment. We analyzed the parameters of the working chamber of the alternating electromagnetic field source of industrial frequency of 50 Hz, we established the dependence of the rate of treatment on the parameters and modes of installation, which are confirmed by laboratory tests. Long-term field studies revealed that the field germination rate of the seeds of spring barley treated with EMF IF, even under adverse weather conditions, exceeds by more than 8% of the field germination rate of control samples

Description
This article presents main water supply systems and justifies the choice of direct flow of water supply system in the application of regulation of electric drive for pumps, which doesn’t have any tanks to create pressures required for fire-governmental purposes. This avoids interruption in the supply of reserve while water freezing. In the article the substantiation of the necessity of implementation of adaptive algorithm in modern-WIDE frequency converters by a substantiation of the number of stages of ratio control of voltage-frequency mains. It was revealed that the number of degrees of regulation of 10-12 gives optimum. Modern frequency converters allow you to change the regulation law, establishing 3-5 points of regulation. Therefore, the introduction of adaptive algorithm will reduce the power consumption of the electric drive of the pump of the water supply system. The article shows the simulation model of the "the converter frequency-induction motor," plots of the stator current of mains frequency and active power, surface speed and phase current when changing the voltage and frequency of the mains. These dependences confirm to have applicability of adaptive algorithm in the regulation of modern frequency converters with the skalar administration. Simulation model confirms the sub-physical experiments on a real motor and frequency converter with adaptive control algorithm. As a result of the selection of the parameters, we obtain the voltage reduction of the phase current, and reduce electricity consumption by 5-7%

Description
The article explains the importance of the transport process when performing repair jobs of asphalt roads. The scheme of the technological process was drawn up; job steps were identified, while the latter may be characterized by non-productive downtime of transport as well as that one of technological machines. We have analyzed the following steps of the flowchart of the road concrete mix transportation: the preparation of the road concrete mix for transportation, loading, transportation, unloading, laying and packing. The transportation of goods starts at the working site of their production and ends at the site of their consumption. The transportation process is a multistep and multioperational process having the greater diversity of technological, operational and economic operations, which must be correctly organized. It is extremely important to deliver the road concrete mix of coating plant (OP) just in time, while avoiding the unproductive idle standing of the equipment, the deterioration of the mixture, as well as performing the job steps at minimum transportation cost savings. The successful combining of the steps of the concept organization of the road concrete mix transportation (coating plant, asphalt laying step, transportation step) will improve the performance and will provide the reduction of the job cost. One must perform the coordination of job steps on different road sections using information technologies and communication facility
