Raising of problem. Natural calamities, technogenic catastrophes and failures, result in destruction of building objects. Under the obstructions of destructions there can be victims. The most widespread technogenic failure are explosions of domestic gas. The structure of obstructions changes depending on parameters and direction of explosion, first of all size and location of wreckages. Sorting out of obstructions is executed by machines and mechanisms which do not answer the requirements of these works, that predetermines falling short of logistical support to the requirements of rescue or restoration works, and it increases terms and labour intensiveness of their conduct. Development of technological decisions is therefore needed for the effective sorting out of destructions of building objects. Purpose. Development of methodology of determination of logistical support of processes of sorting out of destructions of building and building. Conclusion. Experience of works shows on sorting out of the destroyed building objects, that they are executed with the use of imperfect logistical support, which are not taken into account by character of destruction of objects and is based on the use of buildings machines which do not answer the requirements of these processes, that results in considerable resource losses. Building machines with a multipurpose equipment, which provide the increase of efficiency of implementation of rescue and restoration works, are worked out. Methodology of determination of number of technique is worked out for providing of material-supply of sorting out of destructions, in particular on the initial stage of rescue works for liberation of victims from under obstructions.

Problem statement. Until now slide bearings are used widely in engineering. But the calculation is made on obsolete method that is based on undetermined parameters such as wear of the bearing shell. It is accepted in the literature that if the shaft and liner material are homogeneous, the workpiece surface are cylindrical as they wear and contact between them occurs at all points contact arc. Research objective. The purpose of this study is determine a friction torque in the slide bearings of power-basis parameters. Conclusions. Since the friction is primarily responsible for wear of cinematic pairs “pin – liner” and “pivot — liner” slide bearings. It is shown that the friction torquesof angles wrap, that are obtained by the formulas and given in literature, are not only qualitatively but also quantitatively, namely, the calculation by literature to the formulas the friction torques are proportional to the angle wrap and the calculation by improved formulas the friction torques are inversely proportional to the angle wrap due to the reduction the normal pressure. Underreporting friction torque at large angle wrap is between 40 and 15 %. The difference in the magnitude of friction torque in the run-in and run-out cinematic pairs with real method of machining is 2...3 %, which it is possible to declare of reducing the finish of contacting surface of slide bearings.

Problem statement. Ecopolices are the newest stage of the urban planning. They have to be consideredsuchas material and energy informational structures, included to the dynamic-evolutionary matrix netsofex change processes in the ecosystems. However, there are not made the ecopolice classifications, developing on suchapproaches basis. And this determined the topicality of the article. Analysis of publications on theoretical and applied aspects of the ecopolices formation showed, that the work on them is managed mainly in the context of the latest scientific and technological achievements in the various knowledge fields. These settlements are technocratic. They are connected with the morphology of space, network structures of regional and local natural ecosystems, without independent stability, can not exist without continuous man support. Another words, they do not work in with an ecopolices idea. It is come to a head for objective, symbiotic searching of ecopolices concept with the development of their classifications. Purpose statement is to develop the objective evidence for ecopolices and to propose their new classification. Conclusion. On the base of the ecopolices classification have to lie an elements correlation idea of their general plans and men activity type according with natural mechanism of accepting, reworking and transmission of material, energy and information between geo-ecosystems, planet, man, ecopolices material part and Cosmos. New ecopolices classification should be based on the principles of multi-dimensional, time-spaced symbiotic clarity with exchange ecosystem networks. The ecopolice function with this approach comes not from the subjective anthropocentric economy but from the holistic objective of Genesis paradigm. Or, otherwise — not from the Consequence, but from the Cause.

The main objective of the scientific and technical language — describe, explain, describe the natural and social processes and phenomena, technical facilities. Despite the large number of works devoted to the issues of terminology, linguistics still has a reasonable and well-established theory of the term, not fully elucidated interaction terminological vocabulary words from other layers in scientific and technical texts, not fully explored some terminological lexical layers, including construction terminology
