ISOLATION AND SELECTION OF THE NON TRANSDUCING E. COLI BACTERIOPHAGES FOR ANTI-COLIBACILLOSIS DRUGS
DescriptionThe isolation of E.coli phages from samples of natural and waste water obtained during expeditions in the different regions of Russian Federation was carried out. The obtained phages (286 isolates) were tested for their ability to lyse the pathogenic strains of E. coli – pathogenic agents of pig colibacteriosis in Krasnodar region. The study was conducted of their ability to phage transduction, the molecular-genetic characterization and biotechnological parameters of selected bacteriophages. For first experimental design of veterinary drugs was selected 5 coliphages having no ability of plasmids transduction. It has been shown that all the investigated phages are representatives of T4-type phages of family Myoviridae. The reported study was partially supported by RFBR, research projects No. 08-04-99111, 09-04-10132, 16-44- 230855

NONPARAMETRIC KERNEL ESTIMATORS OF PROBABILITY DENSITY IN THE DISCRETE SPACES
01.00.00 Physical-mathematical sciences
DescriptionSome estimators of the probability density function in spaces of arbitrary nature are used for various tasks in statistics of non-numerical data. Systematic exposition of the theory of such estimators has been started in our articles [3, 4]. This article is a direct continuation of these works [3, 4]. We will regularly use references to conditions and theorems of the articles [3, 4], in which introduced several types of nonparametric estimators of the probability density. We have studied linear estimators. In this article, we consider particular cases - kernel density estimates in discrete spaces. When estimating the density of the one-dimensional random variable, kernel estimators become the Parzen-Rosenblatt estimators. Under different conditions, we prove the consistency and asymptotic normality of kernel density estimators. We have introduced the concept of "preferred rate differences" and are studied nuclear density estimators based on it. We have introduced and studied natural affinity measures which are used in the analysis of the asymptotic behavior of kernel density estimators. Kernel density estimates are considered for sequences of spaces with measures. We give the conditions under which the difference between the densities of probability distributions and of the mathematical expectations of their nuclear estimates uniformly tends to 0. Is established the uniform convergence of the variances. We find the conditions on the kernel functions, in which take place these theorems about uniform convergence. As examples, there are considered the spaces of fuzzy subsets of finite sets and the spaces of all subsets of finite sets. We give the condition to support the use of kernel density estimation in finite spaces. We discuss the counterexample of space of rankings in which the application of kernel density estimators can not be correct

THE ROLE OF LAND, WATER AND MINERAL RESOURCES IN THE CONFLICTS IN AFRICA AND THE WAY FORWARD
DescriptionThe scarcity of natural resources has become a serious problem in terms of security in the world. This article examines the role of the limited resources in conflicts in Africa. The main source of conflict is the issue of control of resources and the right to a healthy environment. Here we consider the case of the regional conflicts in the African context. A large number of major rivers in Africa also have been the cause of conflicts between the riparian countries. However, most of these problems have been successfully solved, and in many cases, this process led to the formation of regional blocs for economic and diplomatic cooperation in the region. In addition to inter-State disputes, there are also internal disputes among regions or states within the same country for the control of resources. However, in some cases these regions have developed wellcoordinated approaches to resolving the disputes: either by judicial apportionment, congressional action or based on negotiated compacts. In general, we believe that a careful application of equitable resource-sharing formula to volatile areas is a basic condition for peace and stability in Africa

Description
Experience shows that in the current situation of high demands and large intensity of combat training of troops and fleet forces in the military and ship’s administration supervision can be and objectively necessary to permanently find new principles of management in order to search reserves, savings and increasing efficiency. Analysis and diagnostics of economical activity is an effective mean of familiarization the results of the structural units of logistics service. The article presents an introduction of mathematical methods in the process of checking the status of separate issues weapons, military equipment and economic activity. The result of checking the status of separate issues weapons, military equipment and economic activity should be the analysis of status of audited procedures management. The checking of status of separate issues weapons, military equipment and economic activity of the logistic service should be performed using the parameters set and approved by he governing documents of the Russian Federation Ministry of Defense on the basis of expert method, where experts are members of the stocktaking groups. Based on conducted research, there was developed a software algorithm, which is proposed to use in the procedure of checking the status of separate issues weapons, military equipment and economic activity of the logistic service and their quantitative assessment

ASSESSMENT OF MILITARY AND PROFESSIONAL ADAPTATION OF CONSCRIPTS
DescriptionThe article presents a methodology of assessment of military and professional adaptation of conscripts considering a 12 month length service. This methodology intended to be used by officers (supervisors) at work with staff to monitor the dynamics, diagnostics and forecasting of the military personnel adaptation process and the adoption of corrective and management solutions. It includes criteria for testing and monitoring the daily activities, which are integrated with common methodological positions into the adaptation process of an assessment system. Developed methodology of military and professional adaptation assessment lead to necessity to develop certain types of conscript’s adaptive behavior. To make this methodology more effective in implementation, there was developed software, which allows receiving recommendations by command staff for the management of the adaptation process of each soldier after initial data entering. The developed software is aimed to be used by command staff for improvement of the effectiveness of subordinate personnel and does not require a special training
