In the article we have stated results of the monitoring of local populations of rare plans species in the territory of the nature monument (NM) of the Rostov region «Raznotravno-tipchakovo-kovylnaya steppe» (Zernogradsky district). Vegetation of NM belongs to the poor version of the Azov steppe, flora contains 291 species, including 13 rare species (Astragalus ponticus Pall., Bellevalia sarmatica (Pall. ex Georgi) Woronow, Calophaca wolgarica (L. f.) DC., Caragana scythica (Kom.) Pojark., Centaurea talievii Kleop., Crambe pinnatifida R. Br., C. tataria Sebeok, Crocus reticulatus Stev. ex Adam, Eriosуnaphe longifolia (Fisch. ex Spreng.) DC., Iris pumila L., Stipa pulcherrima К. Koch, S. ucrainica P. Smirn., Tulipa schrenkii Regel), included in the Red List of the Rostov region, including 6 species included in the Red List of the Russian Federation. In 2016 were specified the patterns of rare species distribution in NM borders, and also other important parameters of their populations (number, density, age structure, etc.). The group of rare plants species, included in the Red List of the Rostov region, in the territory of NM includes 65 % of their total number known in Zernogradsky district. The special sozological value of NM is determined by the large local populations of Calophaca wolgarica, Astragalus ponticus and Crambe pinnatifida. Local populations of all rare species in the territory of NM can be considered to be steady as inhabit here during last 50 years
The article is devoted to the analysis of law definitions and its influence on law discourse-text universe. Linguistics can interfere into jurisprudence by introduction of mini-dictionary into the text of the law. Law is a mixture of legal norms and regulations plus philological pearl – thesaurus. It is not only reasonable but necessary to adopt definition to the body of law, because the meaning of the term can vary depending on goals and aims of the law. The legislation of the Krasnodar territory is analyzed in the article in the philological aspect. The choice of examined laws is proved not only because of the agrarian component of the region but also because of the presence of powerful base of tourist-recreational services. In the article there is regional evidential material. The exact actual laws are depicted, philological assessment of their language and legislative importance is given, it is mentioned that conceptual instrument is present in main normative acts. The problem of methodological basis is actualized. In the research the contrastive analysis of similar laws of the Krasnodar territory, Great Britain and southern states of the USA in discourse-text universe is conducted. The conclusions can determine the processes of language interference in today’s changeable picture of the world
The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
The accumulation of heavy metals was studied in different component parts of a White squash (skin and flesh, flesh, seed skin, seed kernel, peduncle). It is known that the basic source of feed for agricultural crops are mobile water soluble organic and mineral soil combinations which are polluted by heavy metals in different degrees. In the process of their migration they are able to accumulate in different parts of plants or to disperse. The mechanism of quantitative estimation of migration of heavy metals in direction of removal of mobile water soluble soil combinations to various parts of a White squash is developed by the author. The ranks of mobility of heavy metals are made from the most mobile manganese to the most indifferent iron. The model of estimation of mobility of the rest spectrum of heavy metals is chosen, namely: lead, cadmium, zinc, copper, nickel, cobalt in relation to manganese and iron. Basing on the position of a separate element in a mobile rank and its concentration it is possible to define the source of entering to a squash fruit. It may be water soluble soil combinations, irrigation water and atmospheric aerosols

The term "methodology" is understood differently. Methodology - the doctrine of the organization. Methodology (from the "method" and "logy") - the doctrine of structure, logical organization, methods and means of action. Methodology - the system of principles and methods of organization and construction of theoretical and practical activities, as well as teaching on this system. From these definitions it follows that the methodology - is an intellectual base rod defining approach to specific activities to management decisions. The methodology, which adheres to the manager, lies at the heart of its activities, determines its success or failure, manifested in the consequences of decisions. We give some examples of methodological errors which lead to wrong management decisions. So, the person who seriously requires providing "maximum profit at minimum cost" should be classified into one of two classes, which can be briefly described as "fools" and "liars". Profit must not be the sole purpose of business. The following section will discuss the methodology in place of conducting various scientific economic and technical studies. A natural continuation of the topic - the wording of some of the methodological problems using mathematical methods
The aim of the article is theoretical and experi¬mental confirmation of the possibility to improve the acceleration performance of tractor units by in¬stalling a tow hitch with variable stiffness. Application of speed tractors in agricultural pro¬duction meets a number of difficulties associated with the unsteady processes, especially while accel¬erating of machine and tractor units. The resulting large inertial loads during acceleration lead to loss of engine power, due to which the machine and tractor unit operates with less performance and economy. Our analysis of published studies shows that the acceleration performance of tractor units is greatly influenced by the rigidity of external links in the form of coupling devices installed between the trac¬tor and the agricultural machine. The design of the tow hitch with variable nonlinear stiffness for class 1.4 tractors is offered. The results of theoretical and experimental studies on the effect of the proposed tow hitch with variable nonlinear stiffness on the acceleration capabilities of machine and tractor units based on class 1.4 tractor are shown. Based on the analysis of characteristics obtained by the analytical and experimental ways, it was proved that the use of the hitch with a variable non-linear stiffness on class 1.4 tractor helps to improve the acceleration performance of the machine and tractor unit
