The article considers the crop rotation with different saturation of rice and measures of struggle against the cereal and wetland weed
The article gives the estimation of the influence of Agro industrial complex on the state of small water basins. Hidrochemical and microbiological researches of rivers at their main stages of water regime were conducted. Seasonal fluctuations of main polluting substances were revealed. For microbiological estimation of the water quality in investigated water basins, there was done the calculation of the total quality of microorganisms. At the same time, a quality control of sanitary demonstrative microorganisms was done
The results of ecological modeling of regularities of formation of vegetation sand massifs of Don basin are presented in the article
In the article, for the first time we have considered group of electrons radial to atomic nucleus with equal value of orbital quantum number and equal sequence of emergence on subshells. As a result of this consideration, the exclusion orbital principle which regulates distribution of electrons in atom on values of spin has been established. On the basis of this principle, the orbital system of distribution of electrons which adequately corresponds to the valid system installed according to the spectral analysis is developed. From positions of orbital system the new explanation of reasons for deviation of the valid system of distribution of electrons in atom from ideal system of consecutive filling of electron shells has been offered and the nature of the empirical rule is opened. The structure of periodic system is also considered and the explanation of the reasons pair repetition of the periods on number of elements is offered. It is thus shown that borders of the chemical periods are displaced relatively borders of the periods of orbital system on two elements to the left
Theoretical and experimental studies of engine of machine and tractor aggregates in unsteady modes of operation of working processes that use controlling load impulse are described
In the article below the following items are represented: existing methods for design of electroactivator for water solutions, processes within an electroactivator are examined, the new formulas for calculation of the main characteristics of electroactivator are proposed, dependences of the parameters upon the factors which influence on device functioning are plotted, conclusions regard processes and proposals for design and operating are made
Directions of effective functioning of system of process engineering of complex harvesting of cereal crops are stated
Daily watering (for 7 days) with probiotic "Provagen" at a dose of 14 g/head and complex probiotic (14 g/head) with chitosan (0.8 g/head) has optimized homeostasis, as evidenced by a strong tendency to reduce to the normative values of the relative content of neutrophils in the blood of calves
The object of the article is to consider the surrounding factors of city passenger motor transport of the municipal union «City of Magadan» and to estimate the degree of their influence to municipal transport infrastructure by means of the PEST-analysis, SWOT-analysis, a method of pair linear correlation, and a method of profile city surroundings. As a result of this analysis, the basic directions of the strategy of city passenger motor transport development are defined, some recommendations improvement of management efficiency by public transport from the institutions of local government are made
The article is devoted to developing and implementing an investment project of the purchase of livestock or meat after slaughter industry in Mongolia for deep processing and distribution in the territory of Tuva and other regions of Russia
