The article researches two close comedy genre models if the first third of the 19 century – a light (a high society, genteel) comedy and a vaudeville – a society comedy version. Its principally different staging is revealed which is connected with a high literature tradition in the first case and a folk-festive comic in the second case which in its turn specifies fundamentally different interpretation of the main characters
After analyzing scientific papers on the topic of many
scholars, the author focuses on the situational
approach as a major factor of the organizational
aspects of the investigation planning by an
investigative team in cases of multi episode complex
collective crimes. It has been suggested that the
planning and organization of the investigation is
preceded by the predictive assessment of the
investigation situation, determination of the pattern of
a detective’s actions and programming and simulation
of the investigation process. All processes require the
implementation of organizational and administrative
activity of the head of the investigative team.
However, the initial investigation planning for one or
more crimes is reduced only to a description of the
investigative situations, to the presentation of a list of
investigative actions and operational searching
activities without the agreed plan and appointment of
the participants in such activities. Consequently, the
situational approach in planning can minimize errors
during investigative activities and optimize the work
of the investigative team dealing with the multi
episode crime particularly complex in terms of
investigative and procedural actions and operational
and searching activities

On the up-to date stage of development of the Russian economics, the problems of forming of competitive reproducing potential of industrial organizations, arrangement of usage, development of methods of diagnostics, choice of development directions are considered to be the urgent problem, since they suppose full realization of economic possibilities and development of effective strategies of future development
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
