The purpose of the research is the development of new methods of the estimation of the importance of scientific journals. It is known that for assessing the significance of scientific journals it is used a universally recognized impact factor, which reflects the average number of citations to the articles published in the magazine for a certain period of time. For a more objective assessment of the significance of the journal in the scientific community we use such indicator as the index of efficiency, which reflects how quickly the articles in the scientific community published in the journal become known and recognized. At the same time, the impact factor as one of the scientometric indices has inherent definite disadvantages, the main of which - the stimulation scientific edition to the artificial reduction of the number of published articles, instead of increasing demands to improve their scientific level. It is necessary to develop a method of assessing the significance of the journal for the scientific community, preserving the dignity of the impact factor and reduce its disadvantages. Application of extra scientometric indicators, in addition to the impact factor and the index of efficiency, will allow assessing the importance of the journal for the scientific community more objectively. Methodological bases of the research are: a systematic approach (considering science as a social institution in close connection with the society as a whole), metasystem approach (considering the scientific community as a metasystem, i.e. a system with a relatively independent components), qualimetric approach (considering the importance of the scientific journal as a latent variables that reflect a variety of criteria), sociological approach (considering the scientific publication as a social system, the intensity of interaction with other society)
It is shown, that use of average characteristics in the formulas, which interconnect penetrability of filtration barriers with porous structure parameters, is relevant only for several kinds of membranes
The mathematical model and the flow chart of the algorithm of the parameters and operating modes optimization of the multifunctional harvester on the basis of a pull-type combine harvester on the straight combining with the winnowing of grain are developed
The activity of many state and municipal institutions in Russia is based on obsolete business models which do not maintain efficiency of management and implementation of regional and municipal development strategy. This article is devoted to the possibility of clear identification of problem areas and taking adequate control measures
The problems of quality of services and issues of cost management on the quality of services are analyzed. Special attention is paid to companies that provide services of audit, consulting, examination and development of measures to improve fire safety and a labor safety at the enterprises. Problems of quality of ser-vices have been classified. Results of the analysis of functions, methods and instruments of product quality control have been presented
The article is devoted to the study of the spatial
distribution of air temperature, precipitation and their
ratio in the form of moisturizing factor of the Mayma
river basin. Calculations of the vertical and horizontal
gradients are hold. Cartographic models of the
distribution basic climatic indices are also constructed
