Diffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented

CULTIVATION OF VEGETABLE PEAS OF VARIOUS TERM OF CROPS ON THE IRRIGATED SOILS OF THE SOUTH OF RUSSIA
The efficiency, the vegetative period, duration of cleaning of grades of vegetable peas of various term of crops on the irrigated soils of the South of Russia are resulted in the article
Criteria of an estimation and a condition of antierosion actions on various types of the agrolandscapes providing the termination or minimizing of erosive processes of soil and increase of productivity of erosioned unproductive soils are resulted in the article
In the article, the results of researches on influence of various agrotechnical receptions on prod-uctivity and quality of a winter wheat on a cornon-grain predecessor are resulted
The data about results of researches on revealing of optimum irrigation modes, features of water consumption of plants and definition of rational level of a mineral food of the cabbage which is grown up in an open ground in the conditions of an irrigation is cited in the article
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
The article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization
New complex-steady black berry technical kind of a grape - "Aleksampelo" is breed in Greece by P.Zamanidi and L.Troshin in 2003 by mating of Firstborn Magaracha with a mixture of blossom dust of Greek black berry sorts of Bakuri and Mavrostifo. Duration of productional phase is 146-155 days. This sort is сильнорослый. A degree of ripening of a vine is very high. Productivity is high. The medial mass of racemations is 230 gr. It differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with sorts of Vitis vinifera L.; it is tolerant to a phylloxera. A flower is bisexual. A racemation is medial, cylinder-conical, medial denseness. A bacca is medial, roundish, blue - black colour, with a dense wax coating. A peel is tight, strong. Pulp and juice with the expressed high quality flavour. Sugar content of juice of baccas is very high. The crop is maintained on bushes duratingly enough. The sort is designed for production of dry red wines of the excellent quality and also for high-grade dessert and sweet wines; it is applicable for development of high-grade juice and compotes as well

The article deals with the problem of increasing innovation activity of enterprises. This aspect is very important because it provides competitive capacity of national economy. Studying of a contemporary condition has allowed to reveal directions of perfection of innovative activity of the enterprises of Russia
In the article the new role of risks is estimated on the basis of the review of the modern economics condi-tions and its conjuncture, stochasticity and unpredictability of variables. Dyadic generalized risk vector in two-dimensional space is designed from vectors of “usual cost” and “risky cost”. It enables analytically to calculate the generalized risks of consecutive logistical chains

In the present article, the synthesis of heterogeneous
genres as a characteristic trait of postmodernist
literature is being considered, with M. Rybakova's
epistolary novel-myth as an example. The specific
modality resulting from such an interlacing of genres
is characterized by stylistic heterogeneity, multilevel
composition and widened spacio-temporal relations.
