Development of the pharmacy market of the Russian Federation causes severe competition among various pharmacy organizations. It results in progressive amalgamation of small-scale and medium-sized pharmacy enterprises.
A survey of enterprise development models as a single socio-ecological-economic system that takes into account the interaction of production and environment is made.
The problem of macro-economic importance of service industries and service economy development, as well as economic trends of service industries development in RF, and their dynamic growth factors are analysed. The Russian service practice innovations are featured.
An amphiphilic diblock copolymer, dextran-block-poly(ε-caprolactone) (DEX-b-PCL), with a series of welldefined chain lengths of each block was prepared by conjugating a dextran chain with a PCL block via aza-Michael addition reaction under mild conditions. For the dextran block, samples with relatively uniform molecul…
The place and role of innovations in the postindustrial period are analyzed. The current state and problems of the innovative sector of the Russian economy are evaluated. Stimulation factors of the enterprises innovative activity are studied.
Lagrange approach to solving problems of heat power plants hydraulic systems dynamics is stated. The calculations and experimental research data of starting-up processes of jet and vane pumps by filling hydraulic line canals of model plant with liquid are named.
Some aspects of the defuzzification method in fuzzy expert information processing in the expert system for technological regulation of the machines are considered. An example of the method implementation is given in the article.
A behavioral model of rheological bodies (viscoelastic material, configuration or system) under load control action, operating in the predetermined fashion for a time, is offered.
Presentation algorithm of the closed contour in sceletons collection is presented. Sceletons collection represents sequence of segments which connect circle centers. Circles fit into the generated contour segment. The major direction of algorithm usage is text information processing without setting up the certain type…
The basic semiotic terms – sign, symbol, emblem – are analyzed. Generalization of the existing notions allows to state that signs are things, objects, or phenomena which denote other things, objects, or phenomena. Symbol can be considered a variety of sign, it is socially significant, emotionally expressive, and polys…
Modeling training is analyzed. It allows to define goals, contents and training stages. Professional competencies development involves modeling methodological knowledge and implementation of the information models in the evolutive training and information technology teaching at the preschool, propaedeutic, basic, spec…
Parcels taken as a principle of a situation assessment and knowledge formation for an intelligent control system are specified. The method of system training is offered - Generalized Knowledge Mining for Technological System (GKM TS). Its main principles and features are shown.
Opportunities of forming theoretical knowledge, practical skills, and control, taking into account levels of information-technological training levels at every teaching stage for college students.
Existence conditions and calculation modes of the exact balanced solution within the limits of international trade model are considered with the theory of graphs application.
Calculation method for three-D rigidity coefficient of the elements of hydraulic drive machines is offered. Description of the stand for field research of the stiffness properties of the hydraulic systems pipelines, including three-D rigidity coefficient, is presented.
Natural connection between Gelfond-Leontyev generalized derivation operators (GDO) and Brenke polynomials is established. Operator extension criterion commuting with GDO up to continuous H(G) space is derived. Domain class when characteristic function of the complex convolution operator always has zero type, is descri…
The scientifically based algorithm of process and equipment of hairpins with thin-walled details characterization is considered. The results of the chosen and calculated parameters of process and equipment are presented.
We address the heat flow study starting from microscopic models of matter: we develop an approach and investigate some anharmonic graded mass crystals, with weak interparticle interactions. We calculate the thermal conductivity, and show the existence of rectification and negative differential thermal resistance. Our…
Peripheral nerve injuries can lead to lifetime loss of function and permanent disfigurement. Different methods, such as conventional allograft procedures and use of biologic tubes present problems when used for damaged peripheral nerve reconstruction. Designed scaffolds comprised of natural and synthetic materials are…
Accelerated aging tests have been extensively used on motor and generator insulation systems to simulate in a short time period the deterioration mechanisms occurring during normal operation of many years, to identify insulation system designs with longer life time and to support the qualification of a new system. The…
