In article results of experiences on studying of aerodynamics of a polydisperse suspension of conversion lime carbonate are resulted. The equations for calculation of speeds and concentration of lime carbonate on length of a tube-dryer are received. The obtained data can be used at designing of industrial dryers.

Keywords: Conversion lime carbonate, drying, tube-dryer, aerodynamics.

This paper proposes a method for studying the intensity of inflow and heat extraction subsystem refrigeration unit as the criterion of efficiency of the refrigeration cycle at different stages of the life cycle of the chiller. As an example, adopted Appliance compression refrigerator. 
Keywords: efficiency criteria, the intensity of heat flow, the chiller, and the influx of heat removal, the evaporator.

This article presents an agent-based computational model of civil violence. In the model we present variant of civil violence when central authority seeks to suppress decentralized rebellion. This model involves two categories of actors. ‘‘Agents’’ are members of the general population and may be actively rebellious or not. ‘‘Cops’’ are the forces of the central authority, who seek out and arrest actively rebellious agents. Both type of actors are having attributes and behavioral rules.

Keywords: Legitimacy, Grievance, Perceived Hardship, Risk Aversion, Jail, Neighborhood, Vision Radius, Salami Tacktics, Initial Density, Active Agent, Quiet Agent, Civil Violence, Visualization, Tension, Ripness Index.

The mathematical model formalizes the solution of a problem of optimum control and it is meaningful to minimization of number of regional extremist system (bandit underground) taking into account relative importance of parts making it at the restrictions caused by "will" of the state to fight against extremism and objective dynamics of number of groups of extremists, an ethnosociocultural protestnost defined by factors (protest potential of society). The task was solved by means of imitating modeling on a method of scenarios.

Keywords: Mathematical model, method of scenarios, extremism, dynamics of number of groups of extremists, problem region, North Caucasus.

It is shown that for research of difficult processes of social interaction at the present stage of development of system modeling hierarchical systems of cognitive models, cognitive architecture and the integrated systems of modeling are even more often used. With reference to these processes the system of models should reflect various abstractions of the description of structure, various aspects of her behavior, stages (iterations) of its evolution in the course of functioning and development. It is offered to consider architecture of set of models in a need context for the solution of a task at a concrete investigation phase.

Keywords: process of social interaction, research, modeling, modeling technologies, systems modeling.

The paper disclosed definition "resource potential," "resourcing" and their differences in concepts, the relationship between the security of the enterprise resources and their economic security, proposed a system of indicators forming the economic security of agricultural organizations on the basis of resource supply, defined tools organizational-economic mechanism of formation of effective resource supply system, aimed at improving the safety of the enterprises of the agrarian sector of the economy.

The kinematic synthesis of the unknown parameters of the rectilinearly - enveloped mechanism of jaw crusher presented, which is linked dependencies with known parameters of the crushing chamber, unloading and loading slot. The dependence obtained on the basis of the method of interpolation approximation of functions. The description jaw crusher with complex movement of an agency on a basis rectilinearly - bent around the mechanism is submitted, her dignity and the area of application

Keywords: rectilinearly - enveloped mechanism, kinematic synthesis, and jaw crusher.

The article shows the role of biotechnology in medicine and in the development of modern society and humanity in general. The main directions of updating the application of biotechnology. Much attention is paid to the social aspects of biotechnology - security, bioethics, the moral responsibility of scientists in the world today. At the same time, the article listed the main problems of the test object associated with bioethics and biosafety, as well as identify opportunities to resolve them in order to ensure the safety of biotech progress. Justified impact of knowledge of bioethics on the social motivation biotechnological research and practical applications of biotechnology, which is very important for social cognition.
Keywords: biotechnology, medicine, society, bioethics, social norms, knowledge of bioethics, social responsibility.
