In the article the model of electron is offered with quark allocation of charge density and with white hole in a center. The model abolishes the crisis of inertial and power electromagnetic masses, and at the same time – the point charge problem. The electric white hole is the analogue of black hole in the gravitation. Its electric radius equals about 2/3 of actual radius of elementary particle. Reasoning from harmony of the four got spheres, a white hole can be confidently interpreted as a fourth type white (neutral) quark. Poincare's tensions (springs) lose sense. The results of simulation are added.

In the paper there is described solving a current scientific problem of mathematical modeling of heat-mass transfer processes and elastic-viscous-plastic deformation taking into account the mechanics and sorption creep in hygroscopic capillary-porous materials with variable anisotropic heat and mechanics characteristics. This finite elements method has been developed for the research of the two-dimensional anisotropic intense-deforming state during the capillary-porous materials drying process in an elastic-viscous-plastic area of deformation taking into account the mechanics and sorption creep. There has been elaborated the applied software which consists of the documented classes and provides the possibility to automate the finite-elemental analysis of timber intense-deformation state during drying process.

Strategic company management in dynamic conditions and amongst difficult to foresee changes in the environment as well as the decrease of effective action is a key issue. Planning and implementation of a strategic company development plan based on innovative technologies and marketing, production, research and development (R&D) strategies as well as on staff development and finance strategies. It transpired that the current model of company management which concentrated on problems such as modification of managing structure and subordinate staff and the division of responsibility and authority was ineffective. Good organization and management is one of the more important prerequisites to proper activity of any company. On one hand, the organization structure should be as simple as possible, on the other it should guarantee the proper efficiency of the system action as well as good cooperation with the market and the company’s surroundings. The activity of the company, whatever are its work characteristics, is the weave of the rules of activity of all the employees. For proper and effective company management preemptive reconnaissance of the market, evaluation and prediction is necessary. The following key issues are of note in the article: • the presentation of the set process and the implementation of new, innovative construction and technological and organizational solutions as well as company marketing strategy, • the presentation of innovative methods, of both organization and marketing and of the manner of their use in implementation processes (the increase in employee skills) • the conviction and the assurance in the propriety of use of methods and ways of technology implementation, organization and marketing strategy – innovation.

The work concerns the further development of optoelectronic sensor’s signal converters. The problem of minimizing the parasitic influence of stray uninformative optical radiation and electromagnetic interference is considered. An impedance converter which provides the inductive nature of the impedance of the photosensitive sensor load circuit is proposed and studied.
