The paper considers the possibility to use IR-dried vegetable-based food additives when making nutrition stuffs for therapeutic and disease-preventive purposes. Nutrition is one of the most important factors of the relationship between man and environment. Nowadays burning is the issue to develop the technology to make nutrition stuffs on the basis of available raw stock sources abundant with biologically active substances. Vegetables are the sources of vitamins (A, B3, B6, B9, C, E, PP), saccharides (grape, fruit sugars, sucrose), organic acids (citric, malic, oxalic), mineral substances. Vegetable composition also contains pectin capable to form compounds with heavy metals and excrete them out of the body. In recent years the largest use has been put to vegetable ingredients with minimal moisture: whole or ground to the size required, up to powder, produced by drying. Particularly common became the latest methods of vegetable raw stock drying including infrared (IR) drying. IR-dried vegetables retain their natural color, aroma and flavor. They are quick to resume their original size in water; they do not lose their beneficial properties in continuous storage. A physiological experiment established that food additives of beet, pumpkin and carrot influence some physiological and biochemical indices in rats. Powder-like dry food of vegetables can be widely used by public catering establishments and food industry as food and flavor additives and for manufacturing therapeutic and diseasepreventive stuffs.
The paper expounds the research data on probiotic BS 225 administration effect on the growth rate in Siberian sturgeon young fishes grown under the conditions of industrial workshop on the fishery farm «Novosibirsky Rybzavod». To grow the fishes, fish-breeding pools made of concrete were employed which were supplied with a pit toremove feed remains and excrements, storage capacitor, mechanical and biological unit for pollution abatement to get the pools ready to be filled with water. The 1st experimental group of fishes received the preparation at the dose 10 mcl per kg; the 2nd one did 5 mcl per kg. The dose was recalculated after each 10 days. To clarify the effect of the preparation the control weighing was done regularly. The fish weight and body length, the largest height and some plastic traits were determined with common techniques. According to the data obtained, the absolute weight of the experimental underyearlings exceeded that of the control analogues when fed the microbiologic preparation. Expressivity of the absolute weight change depended on the preparation dose. The maximal gain in weight was recorded with the preparation given at the dose 10 microliters per 1 kg of weight. The sturgeons of the 1st experimental group exceeded the analogues of the 2nd experimental group on the 2nd and 3rd months of examination.
The paper shows the part played by the introduction of blood group systems alleles as the factor of formation of allele pool of immune genetic markers in SB RAS ICG diminutive pig population. (further DMP) The DMP blood added to the blood of Landrace (1998) and Vietnamese boars (2005, 2010) made the DMP herd have the alleles, such as Eedf, Ladhjl and Lagim. It was the introduction of the alleles from Landrace and Vietnamese boars rather than convergation processes that made the crucial contribution to the phylogenetic mapping of the modern DMP population, that being well-reasoned and testified to. Based on the allele presence/absence, two major components were spaciously plotted in the map through Euclidean distances. The components show DMP clusterized with the pig breeds and populations which were used in their production. Given the grouping happened based on the 2013 data about the presence or absence of blood group systems alleles, the modern DMPs are found in the same cluster with Svetlogorsky mini-boars, minisibs and Vietnamese breed. Given the clusterization resting upon the alleles detected in the population founders, DMPs are found in the same cluster with Svetlogorsky founding boars. In addition, the paper shows the contribution of each of the initial forms to the gene pool of the modern DMP population as well as the contribution of each of its founders. Over a half of the blood portion belongs to the Svetlogorsky founding boars, but the contribution of each of the rest of the predecessors constitutes nearly 0.1–0.2.

The provision about the deformation of the bend in connecting rod bars caused by the effect of ICE amplitude-frequent working load emerged in the plane perpendicular to the plane of the swinging connecting rod served as a working hypothesis of research data. Herewith, the direction of the bending moment depends upon the presence and direction of working surfaces angle deviation (WSAD) in the connecting rod bearing. According to the data of different authors, the numerical values in the parameters of angle deviations of assembly surfaces in ICE basic parts after the first operation cycle are many folds higher than maximal permissible values. Assembly surfaces angle deviations (ASAD) in ICE basic parts are characterized by the following parameters: 1) deviation from the axis perpendicularity of cylinders and pockets of crankshaft main bearings( γ 1 ); 2) deviation from axis parallelism of the crankpins and crankshaft main journals ( γ 2 ); 3) conic crankpins ( γ 3 ); 4) axis deviation of connecting rod ends from their being in the same plane (axes misalignment) when a connecting rod bar twisted ( γ 4 ); 5) deviation from axis perpendicularity of bosses and piston openings ( γ 5 ); 6) deviation from axes parallelism in upper and bottom connecting rod ends ( γ 6 ). Analysis of the patterns on the effects of the ASAD parameters mentioned showed that when deviated from the axis perpendicularity of cylinder and bores for the crankshaft main bearings ( δ∆ = γ1 > 0)and the algebraic sum of the rest of the ( γ2+ γ3+ γ4+ γ5+ γ6 = 0,0 ) equaling 0, the connecting rod bar bend direction does not change its direction when the piston moves from the upper dead point (UDP) to the bottom dead point (BDP) and from (BDP) to (UDP).With the error status of the kind in assembly surfaces, the lengthway contact of working surfaces.
