Abstract: FIELD: manufacture of building materials. SUBSTANCE: polystyrene/concrete products with heat-insulation and construction properties are manufactured from composition containing, wt %: Portland cement 68-70, granulated foamed polystyrene 3-6, reinforcing material 5-12 (above 100%), air-entrainment agent (saponified wood resin) 0.02-0.1, plasticizing agent 0.1-0.2, and water (balancing amount). Specified amount of granulated foamed polystyrene is fed into concrete mixer, moistened with a part of tempering water at stirring, and then cement, the rest of tempering water, air- entrainment and plasticizing agents are added. The mix is stirred and molded into products, which is subjected to heat treatment. Saponified wood resin is preliminarily diluted with water at ratio between 1:5 and 1:19 to 8-12% concentration, after which held up to 48 h at 15-35 C. Granulated foamed polystyrene with loose density 25-30 kg/cu.m, fraction 3-5 mm, is moistened with 1/3 tempering water and stirred during 0.5-1.5 min. After addition of Portland cement, the total is stirred for 30-60 sec and then are added remaining 2/3 tempering water, preliminarily diluted saponified wood resin and lignosulfonate or superplasticizer S3 (plasticizers). Resulting mix is stirred for at least 2 min and thoroughly warmed from cement hydration heat to temperature 35-75 C until coherent porized homogenous structure is obtained. When molding, polystyrene/concrete mix is delivered with the aid of screw pump into concrete form with, installed therein, cellular framework made from reinforcing material: threads or sticks with diameter (0.5-3)d, cells (50- 100)x(50-100)d, laid in 2-4 layers, and binding transversal sticks with diameter (1.0-4)d and step (100-200)x(100- 200)d, where d is average diameter of polystyrene granules. Protective layer between concrete reinforcement and outside surface is at least 25 mm. Mix filling concrete form is smoothed and held at 15-35 C for at least 12 h. Thus obtained polystyrene/concrete product, after stripping of formwork, is sprayed during 30 days with water once every three days starting from 8th day after laying mix into form. EFFECT: decreased bulk weight and heat conductivity of products, and reduced consumption of starting components. 1 tbl

Abstract: FIELD: oil extractive industry. 
     SUBSTANCE: method includes pumping of working agent through force wells and extraction of oil through product wells from the beds. At least one well is stopped, previously perforated intervals are cemented, cement bridge is placed in the well with forming of new artificial pit-face above perforation intervals. At depth higher than upper interval of perforation a new slanting shaft of well is drilled with junction to horizontal shaft in non-extracted bed. New face is placed at distance of no less than 50m from face of previously drilled well. Drilled well is used as force well. Length of horizontal portion of well is selected on basis of needed well acceleration. Pressure and volume of pumping into drilled well is lessened for excluding outbreak of working agent into adjacent beds through behind-column space of main well shaft. Pumping of working agent is performed in cyclical mode. In product wells face pressure is heightened for value for which pressure of pumping working agent into force well was lessened. 
     EFFECT: higher oil yield due to better coverage of bed by operations, and use of previously idle productive beds.

Abstract: FIELD: optoelectronic industry; methods of materials processing. 
     SUBSTANCE: the invention is pertaining to the field of optoelectronic industry, to methods of materials processing, in particular, to the methods of scribing and separations of laminas having the light-emitting structures. The invention may be used in the optoelectronic industry at production of light emitting diodes (LEDs). The main purpose of the invention is the problem to develop a method of separation of the solid transparent laminas with the light-emitting or microelectronic structures using a laser emission. The method of separation of laminas is realized by creation of lines formed at the expense of defects caused by the laminas piercing and located in a direction of the technological tracks one over another in the different depths of the sample with a specially chosen range of parameters characterizing the relative poisoning of the defects layers. A laser emission is introduced perpendicularly to a lamina from the lamina side, which does not contain the light-emitting structures. The first layer of defects is formed at a distance from the surface of no more than one depth of a defect. Defects in the subsequent layers in depth are formed at a distance between the centers the defects equal from one up to four diameters of the defects. 
     EFFECT: the invention presents the method of separation of the solid transparent laminas with the light-emitting or microelectronic structures with the help of a laser emission.
