Interaction Intensity

We suggest definition of effective interaction intensity for soft hadron collisions and discuss its energy dependence in the preasymptotic region. Practical importance of this quantity consists in separation of rising interaction radius from effective interaction intensity increase both contributing to the total cross-section growth. It would be helpful for understanding the origin of this growth at the accelerator energies. The essential feature is that the effective interaction intensity is an experimentally measurable quantity.

The paper provides a definition of the economic mechanism for managing the communication business processes of industrial enterprises in the context of globalization as a set of a system of relations, authorities, forms and methods of organization and operation, which are regulated by legal and other norms of activity and provide effective interaction in internal and external environments. This allows to deepen the understanding of the essence in the context of globalization under the orientation towards communication (we mean interaction first of all). The composition of the comprehensive economic mechanism for managing the communication business processes of industrial enterprises is studied. This mechanism includes organizational, economic, legal, political, technical and technological, market, production, social, motivational, adaptive and communication submechanisms. This allows further formalization of the process of elemental improvement of the communication business processes of industrial enterprises. The components of mechanism are detailed. In particular, the economic submechanisms include the mechanisms of profits distribution, economic stimulus, financial, equity, investment and reinvestment in development and other mechanisms. The legal submechanisms include the mechanisms, which govern communication and professional legal relations. Organizational submechanisms include structural mechanisms, administrative and information mechanisms that ensure the development and modernization of communication activities at the enterprise, its information security. Political submechanisms include mechanisms of information policy, social and economic policy and foreign economic policy. Market submechanisms include the ones of market competition, demand and supply, etc. Social submechanisms include the ones of transparency of doing business, social responsibility, social and psychological impact, etc. Production submechanisms include the following ones: resource, implementation of new types of software and hardware and other. Technical and technological submechanisms include the ones of scientific and technological progress, technological updates. Motivational submechanisms include the mechanisms of material and non-material incentives of personnel. Adaptive submechanisms are the submechanisms of innovative development (including implementation of innovations in information field), managing the personnel potential, etc. Communication submechanisms include the ones of information-and-analytical activities (including research conducting); external communications (including the system of integrated communications tools, modern telecommunications and communications facilities); internal communications (including creating corporate culture). Key words: economic mechanism, submechanisms, management, communications, business processes, industrial enterprise.

Comprehensive Framework

Experimental studies of hypernuclear dynamics, besides being essential for the understanding of strong interactions in the strange sector, have important astrophysical implications. The observation of neutron stars with masses exceeding two solar masses poses a serious challenge to the models of hyperon dynamics in dense nuclear matter, many of which predict a maximum mass incompatible with the data. In this paper, it is argued that valuable new insight can be gained from the forthcoming extension of the experimental studies of kaon electro production from nuclei to include the 208Pb(e,e′K+)Λ208Tl process. A comprehensive framework for the description of kaon electro production, based on factorization of the nuclear cross section and the formalism of the nuclear many-body theory, is outlined. This approach highlights the connection between the kaon production and proton knockout reactions, which will allow us to exploit the available 208Pb(e,e′p)207Tl data to achieve a largely model-independent analysis of the measured cross section.

Introduction. The purpose of this article is to define methodological grounds of assessment of agricultural land using efficiency. The article is devoted to definition of the indicators system of land using efficiency. Methods of research. The solution of the tasks in the article is carried out with the help of such scientific and special research methods as: analysis and synthesis, systematization and generalization, the dialectical approach. Results. The structural balance between cost of land and production resources has been investigated, which leads to the need of many alternatives for the purpose and use of the respective territories on the basis of the modern system of land using efficiency assessment when determining the benefits of land resources using for agricultural production. Originality. It has been proved that to create and enforce a uniform indicators system of land using efficiency is necessary to determine all the factors that affect land use, to reflect the degree and type of each factor influence using the indicators of efficiency of the land use. Indicators of economic efficiency of land using and the intensity of land use are systemized. Practical importance. The methodical approach of agricultural lands using evaluation in the following areas has been justifed in the article: completeness of land use, rational land use, the level of land use intensity, efficient land use. The methodical approach has been presented to the calculation of potential losses from specific land uses in specific circumstances. It is proposed to assess the land using efficiency on the basis of indicators calculations of environmental and economic damage. Basic scientific principles can be used in the practice of agricultural enterprises. Keywords: management, methodological bases, evaluation, efficiency, and agricultural land use.

We report numerical investigation of the short range interaction influence on the two-dimensional quantum scattering of two dipoles. The model simulates two ultracold polar molecules collisions in two spatial dimensions. The used algorithm allows us to quantitatively analyse the scattering of two polarized dipoles with account for strongly anisotropic nature of dipolar interaction. The strong dependence of the scattering total cross section on the short range interaction radius was discovered for threshold collision energies. We also discuss differences of calculated scattering cross section dependencies for different polarisation axis tilt angles.

Context.The spectrum of the hydrogen atom was explained by Bohr more than one century ago. We revisit here some of the aspects of the underlying quantum structure, with a modern formalism, focusing on the limit of the Balmer series.Aims.We investigate the behaviour of the absorption coefficient of the isolated hydrogen atom in the neighbourhood of the Balmer limit.Methods.We analytically computed the total cross-section arising from bound-bound and bound-free transitions in the isolated hydrogen atom at the Balmer limit, and established a simplified semi-analytical model for the surroundings of that limit. We worked within the framework of the formalism of Landi Degl’Innocenti & Landolfi (2004, Astrophys. Space Sci. Lib., 307), which permits an almost straight-forward generalization of our results to other atoms and molecules, and which is perfectly suitable for including polarization phenomena in the problem.Results.We analytically show that there is no discontinuity at the Balmer limit, even though the concept of a “Balmer jump” is still meaningful. Furthermore, we give a possible definition of the location of the Balmer jump, and we check that this location is dependent on the broadening mechanisms. At the Balmer limit, we compute the cross-section in a fully analytical way.Conclusions.The Balmer jump is produced by a rapid drop of the total Balmer cross-section, yet this variation is smooth and continuous when both bound-bound and bound-free processes are taken into account, and its shape and location is dependent on the broadening mechanisms.

The distinction between wanted and unwanted fertility has been crucial in many of the more intense debates in recent decades over the nature of contemporary fertility declines and, in particular, the potential impact of expanded provision of family planning services. In a much-debated article published in 1994, Pritchett argues that decline in desired fertility is overwhelmingly the principal source of fertility decline, with the implication that family planning programmes are of little consequence. I revisit this debate drawing on a far larger body of survey data and, more importantly, an alternative fertility specification which relies on a non-conventional definition of wanted and unwanted fertility rates and which distinguishes rates and composition. Decompositions of fertility decline in the period from the mid-1970s to the present are carried out for 44 countries. The decomposition results indicate that declines in unwanted fertility rates have been at least as important, if not more important, than declines in wanted fertility rates. Surprisingly, shifts in the proportion of women wanting to stop childbearing—i.e., changes in preference composition—has contributed very little to fertility change in this period. Further, decline in wanted fertility and increases in non-marital exposure (due largely to delayed entry into first marriage) have also made substantial contributions, although on average they fall short of the contribution of declines in unwanted fertility rates. That declines in unwanted fertility have been an essential feature of contemporary fertility decline is the main conclusion from this research. This in turn opens the door to new perspectives on fertility pre-, mid-, and post-transition which recognises the inter-dependencies between fertility demand and unwanted fertility rates in the determination of the overall level of fertility.

The article touches upon the topic of pedagogic communication. A review of psychological and pedagogic approaches to the definition of communicative qualities necessary for the pedagogue to organise effective interaction with students, as well as for the organisation of personality-developing educational space. The emotional side of the attitude of students to educational activity, consisting in satisfaction with this activity is considered. Mathematical processing of the data showed the presence of a statistically significant relationship between the degree ofmanifestation of communicative qualities of the pedagogue and the level of satisfaction of students with educational activities in the classes of this pedagogue. It is revealed that the most pronounced relationship of satisfaction with educational activities with indicators of pedagogic cooperation and emotional attractiveness of pedagogues. The author emphasises the need to develop the communicative qualities of future pedagogues in the system of higher pedagogic education. The article will be of interest to specialists, pedagogues of higher education.

Definition Of

Here we present a guide on ion mobility mass spectrometry experiments, which covers both linear and nonlinear methods: what is measured, how the measurements are done, and how to report the results, including the uncertainties on mobility and collision cross section values. The guide aims to clarify some possibly confusing concepts, and the reporting recommendations should help researchers, authors and reviewers to contribute comprehensive reports, so that the ion mobility data can be reused more confidently. Starting from the concept of the definition of the measurand, we emphasize that (i) mobility values (K0) depend intrinsically on ion structure, the nature of the bath gas, temperature, and E/N, (ii) ion mobility does not measure surfaces directly, but collision cross section (CCS) values are derived from mobility values using a physical model, (iii) methods relying on calibration are empirical (and thus may provide method-dependent results) only if the gas nature, temperature or E/N cannot match those of the primary method. Our analysis highlights the urgency of a community effort towards establishing primary standards and reference materials for ion mobility, and provides recommendations to do so. <br><br><br>
