SOFTWARE OF INFORMATION SYSTEMS FOR A SMALL-SCALE BUSINESS
Description
The particularities of water-supply are considered in article from freezing rivers in regions of spreading the eternally frozen soils (termofrost) of North of Russia. It is brought condition of formation and strategy of determination of parameters melting water receiving sorts – well know as taliks – under riverbeds of rivers. It is offered designs of intake buildings and arrangements on regulation of under riverbed water with protection them from excessive congelation

Description
Two methods were developed, one to assess experimental results by reducing a number of developmental parameters to the overall quality, leading to the overall quality criterion, and the other to optimize processes affected by numerous interacting factors, in-vitro plant development in this case, by applying a mathematical design of experiment. Single-bud cuttings with one leaf of two Vitis vinifera L. genotypes were excised from the central part of two-month-old in-vitro grown plants and used as explants. The explants were established on bridges of filtering paper in liquid media and on solid media. Eighteen modifications of these media contained five macro-elements, each at three concentrations, and the distribution of these macro-element concentrations followed the law of random numbers (Experiment I). Parameters characterizing arm, leaf and root development of two-month-old plants of each study genotype established on each liquid or solid medium were reduced to the overall quality of plant development. Since the study genotypes differed in the ability to grow on liquid and solid media with different macro-element concentrations and also in the ability to utilize these macro-elements, the dependence of in-vitro plant development on macro-element concentrations was described by different regression equations. That is why the regression equation describing the average outcome of plant development in the two genotypes on liquid and solid media was not as significant and the description of the process was not as adequate (determined) as regression equations calculated for each process. The regression equation which describes the dependence of the average outcome of plant development on macro-element concentrations in Experiment I is as follows: y5 = 0.027 + 0.116x22 + 0.109x2x4 + 0.106x2x3 + 0.114x4. Stepwise calculation of macro-element concentrations to optimize in-vitro plant development was done based on macro-element concentrations of the initial medium of Experiment I as starting points since that medium was best efficient for this purpose by using regression equation (y5) and algorithms of multiple curvilinear stepwise regression according to the Box-Wilson method of steepest ascent. Experiment II was undertaken where macro-element concentrations (‘steps’) were calculated in a stepwise manner to optimize in-vitro plant development of the two V. vinifera genotypes and the rootstock ‘Kober 5BB’. This led to a liquid medium and a solid one which enabled a better plant development in the three genotypes relative to the use of controls: media with ½ MS macro-elements and the initial medium whose macro-element concentrations entered as starting points to calculate ‘steps’ for optimization of in-vitro plant development. The optimized medium contained macro-elements: 318 mg l-1 NH4NO3 (x1), 1188 mg l-1 KNO3 (x2), 370 mg l-1 MgSO4 7H20 (x3) (MS), 370 mg l-1 KH2PO4 (x4), 331 mg l-1 CaCl2 (x5) (MS), and other substances at optimum concentrations adjusted earlier: ¼ MS Fe-EDTA, ¼ MS micro-elements, 20 mg l-1 myo-inositol, 0.1 mg l-1 thiamine (MS), 0.5 mg l-1 nicotinic acid (MS), 0.2 mg l-1 pyridoxine, 2 mg l-1 glycine (MS), 0.1 mg l-1 indole-3-acetic acid, 10 g l-1 sucrose and, only for solid media, 7 g l-1 Difco agar. The optimized medium may be used for propagation of virus-free plants, valuable clones and grapevine genotypes created by gene engineering. The mathematical design of experiment reported in this paper which enables stepwise optimization of in-vitro plant development may be used both in agriculture and in the food industry

Description
A combination of two attributes envisaged in Article 105 of the Russian Federation Criminal Code - organized criminal group and criminal community (criminal organization), add a considerable peculiarity to the process of formation of original data, and criminalistically credible information relating to the category of crimes being considered in the process of evidences formation. The author includes both material and ideal elements in the original information depicting criminalistically credible attributes of constituent elements of the crime and also the circumstances indirectly associated with it, thus, facilitating generation of evidences at the phase of initiation of a criminal case, and enabling identification of circumstances subject to assessment and evidencing at the phase of preliminary investigation

SYNERGETIC INFORMATION THEORY Part 1. Synergetic approach to definition of quanti-ty of information
Description
A new approach to definition of quantity of informa-tion is stated. According to the approach an informa-tion can be defined as data about finite set which is considered like integration and information measure is average length of integrative code of elements. Examples of use of this approach are given.
