Low heat transfer coefficient per unit area is main disadvantage of immersion cooling system. In the theoretical part of the study the main issue was to evaluate the influence of various factors on the convective heat transfer between the solid-liquid interface. The result of this part of study was conclusion that the type of fluid flow in the area of heat transfer is key factor of increase heat convective heat transfer of thermal contact. The Reynolds number is main characteristic of turbulence of fluid flow. Therefore in the experimental part describes study of the effect of the degree of turbulence of the fluid flow at the place of the thermal contact on thermal resistance of immersion cooling system. The design of experimental setup and its main parts is describe further. The result of the experiment is graphic of experimental curve of the thermal resistance of immersion cooling system from the Reynolds number of fluid flow of thermal contact between the solid-liquid interface. The study showed the possibility of local reduction of the thermal resistance of immersion cooling systems to maintain the quality of the thermal management of computing elements that emit significant heat. The results of the study is define the ranges of values of the Reynolds number of cooling system that allows the technical realization at the current dimensions of packages and sizes of microchips sockets.

Jet grouting technology is gaining popularity in practice. Until recently, the main area of application was considered strengthening the bases and foundations, as well as strengthening the walls of trenches in the construction of underground parts of buildings. At the same time there are examples of the use of technology inkjet technology for advanced fixing of deep underground facilities, as well as the mouths of vertical shafts. With the help of this technology is arranged anticipatory lining, which ensures the stability of the construction of the walls and reduce the inflow of groundwater during construction. This greatly reduces the complexity and duration of construction, increased safety. For a broader introduction of jet grouting technology in the construction of deep underground facilities must be a comprehensive study of patterns of interaction with the surrounding structures grouting array of temporary and permanent support of the barrel at various stages of penetration with the influence of the construction technology, heterogeneity of rocks and other factors. This will justify the optimal parameters walling in different environments and to develop effective technological schemes of production work

"The article presents the results of creating a low-cost heat recovery system on the example of ""light"" of the gas infrared emitter by changing a single-layer thin-walled reflector to reflector upgraded on the principle of ""water jacket"" and the results of testing the effectiveness of modernized design on a specially designed stand. As a result, it was concluded that the streamlined design of the reflector gas infrared emitter will minimize the loss of heat towards the ceiling of the building and to avoid condensation on the inner surface of the roofs, a violation of the thermal regime, and as a consequence of premature failure of the roof and walling. In addition, through the use of exhaust heat for heating the coolant (water) flowing through a modernized reflector increases the efficiency of the system of gas infrared heating by 10%."

Studies of gender and family dynamics in society are of great interest for foreign and domestic scientific communities. The results of studying the trends in these areas from the point of view of the students about the "ideal behaviour" of modern men and women are very important, as the social group of young people has always been and is a specific indicator of the state of the society. Today, the availability of various models of the behavior of the sexes is significantly determined by the media. However, new, variable "patterns of behavior" in society does not mean denial of traditional patterns of conduct of men and women. Despite some "westernization" of the young Russians, the national gender factor "works" thereby consolidating society and preserving the national identity of individuals.

Using a device of close homogeneous exponential queueing networks (QN) a mathematical model of an information system functiouning with considering influence of blockings was worked out. A proccessor and the united resourse "channel - external memory" are considered as shared resources. All the users' requests are assumed to be single and homogeneous and the servicing discipline "First Come First Served" is used for sequence of their execution. Analytic expressions are given for calculation of the integral characteristics of the system: the distribuition law of number of messages in a system, the average number of messages at a node, the average sojourn time of a message at a node, the average sojourn time of a message in a system.

Introduction. The present invention generally relates to construction elements for erecting structures, and also to methods of erecting structures with the use of construction elements. Construction elements for erecting structures are conventionally flat elements, which are assembled at a site of construction for erecting a structure. Such flat constructions elements cannot be too wide because their transportation with the use of conventional transportation means is not possible. It is therefore necessary to use the construction elements with reduced width to allow their transportation, or to produce wide construction elements at the construction site. It is therefore believed that it would be advisable to improve existing construction elements and methods for erection of structures with their use. Result. The new technology of construction, based on the use of precast reinforced concrete large-sized spatial structures with variable geometry, allowing transportation without the special vehicles. After truck shipment and restore the geometry, structure is mounted to final position. As a result of the only one mounting stage, load bearing and (or) enclosure structure, permanent formwork of a monolithic slab floor are erected. The proposed technology is confirmed by the author’s priority (Patent № US 8,615,967 B1 / Dec. 31, 2013) Conclusions. Patent search report and the actual fact of the U.S. Patent allow us to draw a conclusion on feasibility and prospect of new technology.
