This article deals with the unification of the elements of wood as on the principle of similarity with the material counterpart. Also estimated the economic benefits of the technical parameters of Glulam. As a result of optimizing the size of these elements. Unification is held on the main criterion of similarity bearing members with the solution graphically. Resulting in optimal size sections are then calculated the opportunity cost of production.
Keywords: unification, glued wooden structures
The influence of the amount of the addition асфальтогранулята on the properties of asphalt mixes and asphalt. Also considered is the impact of technology of filing асфальтогранулята on physical-mechanical properties of asphalt mixes.
Keywords: old asphalt, asphalt, astringent, physico-mechanical properties, homogeneity.
"The mechanical properties of the rubber-cord composite in strengh analysis are described. There is an algorithm of the numerical estimation of the effective (average) properties of the rubber-cord. The effective properties are defined by the successive application of different deformations to the representative volume of the rubber-cord composite (tensions along each coordinate axis and shifts in each cooridinate planes). The effective properties are defined in form of the generalized Hooke's law (for anisotropic materials). A serias of computations in estimatition of the effective properties of double-layer rubber-cord composite was carried out based on the proposed algorithm. The dependence of the effective elastic modules of rubber-cord on the angle of cord was explored. The according graphs are represented in the article."

In article are considered particularities of the aspectual composition of flora and faunas of the republic Kalmykiya, their differences in territorial spreading. It is given analysis антропогенному influence on vegetable and animal world, the Revealed reasons деградации biological potential. Accent is made on condition of the populations of the antelope of the saiga. The Installed factor, influencing upon decision of the problem guard and reproduction охотничье-commercial fauna, danger is shown for vegetable and animal of the world fire.
