CALCULATION OF MAGNETIC RESISTANCE OF A CHISEL WORKING ORGAN FOR FIBREWISE SUBSURFACE TILLAGE
DescriptionThe article presents a calculation of traction resistance chisel working organ for layered subsurface soil treatment and proposed the construction of a working body for subsurface tillage with an elliptical element. We have also included a comparative analysis of traction resistance of workers to the waterline and moldboard tillage

APPLICATION OF CODES WITH NATURAL REDUNDANCY FOR INFORMATION PROTECTION
DescriptionIn the article we provide a survey of cryptographic systems on the basis of unjammable coding; we offer the aspect of codes with natural redundancy for the solution of a problem of simultaneous protection of the information and detection and correction of errors; the demonstration is resulted that codes with natural redundancy are group codes

Description
This work was carried out on the natural territories in the collection and of the Yakut botanical garden (JBG). The object of study was medicinal plants used in the treatment of cardio-vascular system. On the natural territories JBG we have noted 39 species of medicinal plants. 26 species were studied in a culture

Description
The results of a long-term research of the influence of various biologically active agents (a humic preparation Lignogumat and microbiological Baikal EM fertilizer) on a structural state and the enzymatic activity of ordinary carbonated black soil are presented. It has been established that biologically active substances contribute to increased enzymatic activity, humus and improve the soil structure

APOGEOTROPIC SHOOTS OF CEREALS
DescriptionApogeotropic shoots of cereal different of wide range of types of shoots, noticeable differences on characteristic, features of development, their role in the herbage, the seasonal dynamics of crop formation, experiencing noticeable effect on the reaction conditions of soil fertility and humidity. Multiyear cereals in the process of shoot formation form the generative, hidden generative, elongated, short side and underground runners. Multiyear cereals are widely distributed throughout the world, including the tribe Antropogoneae, Chloridaeae, Maydae, Peniceae, Tripsaceae, Festucoideae and others that presented in different parts of the world, and perennial and annual forms. Many cereals are allocated notable longevity, which is largely determined by a wide adaptability to vegetatively propagate. Between northern and southern grasses differences are observed throughout the development of individuals, beginning with emergence. In the southern cereal first sheet has a lancet or ovoid shape and bent at a right angle to his vagina, it is the northern linear subulate form. Cereals are different typology of different shoots. Most large divergence is characterized with erect shoots in both groups of cereals

DIAGEOTROPIC SHOOTS OF PERENNIAL GRASSES IN THE SOUTHERN REGIONS OF THE CIS
DescriptionStudying of perennial cereals of southern and boreal origin led to the allocation of plagiotropic shoots of rhizomes, stolons, that are placed in the soil or on the surface from the apical or lateral kidney of various structures with modified leaves, the beginnings of roots at nodes and developing of type kidney - lengthened shoots. Two types was allocated: type of solid finned cylinder and type of intermittent cylinder with scattered around the periphery of vascular bundles: first include cereals temperate regions and is characterized by separation from the epidermis continuous sclerenchyma ring, the second type (sorghum and millet) no continuous mechanical ring and vascular bundles relatively evenly spaced along the periphery of the shoots
