LABORATORY MODELLING OF FILLING PILE
DescriptionThe grounds of modeling of filling pile static resistance have been offered so as the results of its realization at the laboratory models. The laboratory testing data are compared with the data of field testing of natural piles. The experimental and the model calculated values of bearing capacity shows the correlation coef-ficient 0,692. The laboratory tests confirm the exis-tence of the local maximum of the settlement “accele-ration”. The point of maximum proposed separates two stages of bearing capacity increment process: the stage of lateral surface mainly resistance and the stage of pile bottom mainly resistance

INHERITANCE OF MORPHOLOGICAL CHARACTERISTICS FROM INTERSPECIFIC TOMATO F1 HYBRIDS
06.00.00 Agricultural sciences
DescriptionThe detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability

01.00.00 Physical-mathematical sciences
DescriptionIn the article general mathematical expression for a quantitative assessment of system (synergetic) effect, arising when integrating buleans (systems), being a generalization of sets in system generalization of the theory of varieties and independent of an expedient (algorithm) of formation of subsystems in system is offered. For this quantitative standard the name is offered: «Generalized coefficient of emergence by R.Hartli» because of likeness of its mathematical shape to the local coefficient of emergence of Hartli, reflecting a degree of difference of system from the variety of its base devices. For local coefficient of emergence of Hartli, the generalization independent of an expedient (algorithm) of formation of subsystems in system is offered. Numerical estimates of system's effect are given at integrating of two systems with ap-plication of the author's program to which the refer-ence is given

06.00.00 Agricultural sciences
DescriptionThe analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen
