Siberian State Technological University is the oldest university in Krasnoyarsk, Russia. It was established in 1930 as the Siberian Institute of Forest . Later it was known as the Siberian Technical Institute of Forest , Siberian Technological Institute , Krasnoyarsk State Technological Academy and finally the Siberian State Technological University .Currently 15,000 students are studying in one of the nine faculties.

1H magnetic resonance microtomography imaging was applied to study vascular systems in developing bean (Phaseolus limensis L.) seeds. Using the gradient echo method, we recorded 2D tomographic sections in the sagittal and axial planes of the fruits sampled from a vegetating plant on days 10, 17, 24, and 31 after fertilization. Any vascular connection between the tissues of maternal plant (bean pod and seed coat) and the embryo were undetectable. The embryo has an autonomous branched network of procambial strands in the cotyledons, converging to the embryonic axis. The bean pods are covered with a network of vascular bundles; large vascular strands run along the dorsal and ventral sutures. The seed coat vascular bundles are formed in the process of seed ripening and are represented by a developed vascular system multiply branching in the middle part of the ground parenchyma at the stage of physiological maturity. They are connected with the source of assimilates via the lateral pod veins and a large vascular bundle, entering the seed below the hilum via the placenta. Assimilates enter the external part of the seed coat, which contains no vascular bundles, via the funiculus vascular bundles and hilum tissue. © 2012 Pleiades Publishing, Ltd. Source

As a result of a phytopathological investigation into birch (Betula pendula) stands in the Krasnoyarsk group of areas (south of Middle Siberia), newly appearing and existing nidi of bacterial dropsy have been discovered. The influence of growth conditions on morbid affection in birch forests and the correlation between disease prevalence and characteristics of forest inventory have been established. The specificities of tree affection within phytocenoses and the influence of disease on the sanitary state of birch forests have been discussed. © 2014 Pleiades Publishing, Ltd. Source

The article describes the method for determining the total distortion of digital images. The algorithm for the solution of the problem is developed and consists of the following steps: (i) creating the ideal image of test object according to its real image, (ii) construction of the image distortion vector diagram, (iii) nonlinear regression analysis of the approximable functions, (iv) solution of the interpolation problem, object image correction and object plane contour reconstruction. The square grid is used as a test object. The mathematical model of the image distortion is built using the Nonlinear estimation package of the STATISTICA system. The reliability value of the investigated function approximation is 0.98-0.99 with cubic polynomial applied. The developed method makes it possible to improve the object plane contour reconstruction accuracy. The method may be used in COMPUTER VISION SYSTEMS in intellectual robot-technical systems, pattern recognition etc. © 2011, Institution of Russian Academy of Sciences. All rights reserved. Source

An approach to construction of static models is demonstrated for a fluid ball. Five examples are considered. Two of them are exact solutions of the Einstein equations; the other three are connected with the Airy special functions, the hypergeometric functions and the Heun functions. © 2012 Pleiades Publishing, Ltd.
