N-N Interactions in the Extended Chiral SU(3) Quark Model

The chiral SU(3) quark model is extended to include coupling between vector chiral field and quarks. By using this model, the phase shifts of NN scattering for different partial waves are studied. The results are very similar to those of the chiral SU(3) quark model calculation, in which one gluon exchange (OGE) plays dominate role in the short range part of the quark-quark interactions. Only in the $^1S_0$ case, the one channel phase shifts of the extended chiral SU(3) quark model are obviously improved.Comment: 15 pages, 6 figure

Considering the settling of dispersed water in the water barrier when calculating the explosion-proof distance at the methane explosion in a mine

Gas dynamics equations are used to simulate the interaction of shock waves with water or rock–dust barriers. The model is enhanced with the presence of dispersed water in the flow and its settling on the walls of the working. An approach to the implementation of the method for solving the problem of the propagation of shock waves in a branched network of mine workings, considering the interaction of shock waves with water barriers has been developed. The approach is based on the use of the numerical method of S.K. Godunov. Examples of solving the problem of the propagation of shock waves from a methane explosion in simulated networks of coal mine workings with water barriers placed in them are give

Foreign language professional communicative competence as a component of the academic science teacher’s professional competence

© 2016 by iSER, International Society of Educational Research.The urgency of the problem raised in the article is explained by the increasing demand for qualified specialists who have a good command of a foreign language. The communicative competence of an academic science teacher under the conditions of international cooperation development is of great importance. The article discusses the problem of developing the foreign language communicative competence of academic science researchers and lecturers within the framework of international education and integration into the united European educational area. The research methods are studying and summarizing innovative pedagogical experience, reviewing the results of educational activities of academic science teachers in the sphere of improving the foreign language communicative competence which allow to reveal the status of this scientific problem in the pedagogical theory and practice. The article describes a project aimed at development of the foreign language communicative competence – a system of personal characteristics and skills – which creates perfect conditions to encourage educational and scientific activities of academic science teachers. The materials of this article may be of use to higher school lecturers and researchers who are interested in mastering their foreign language skills to develop their foreign language communicative competence

Pionic Decay of a Possible d'-Dibaryon

The pionic decay of a possible d'-dibaryon in the process d' --> pi + N + N is studied in the microscopic quark shell model and with a single-quark transition operator describing the transition q --> pi + q'. For the d' with quantum numbers J^P=0^-, T=0, we employ a six-quark shell-model wave function with a spatial s^5p [51]_X-configuration with N=1 harmonic oscillator quanta. It is shown that the pionic decay width depends strongly on the mass and size of the d'. In the case that the calculated d' mass is close to the experimental one a small pionic decay width of 0.04 MeV is obtained. This is an order of magnitude smaller than the experimentally suggested value of 0.5 MeV. Two possibilities to improve the calculated width are suggested. The effect of the nonstatic correction term in the transition operator and the influence of the form factor at the decay vertex on the decay width are also discussed.Comment: Latex, 15 pages, 1 postscript figure, accepted for publication in Nucl.

Comparative Analysis of the Process of Training Education Managers in Educational Institutions

Context: A significant part of future specialists receive only practical skills without formal practical exam situation. In this regard, there is a need to train a manager who can adapt and be ready to carry out his/her activities in a specific profile interaction. The aim of the experimental study was to develop and test the advanced working hypothesis about the possibility of effective formation of readiness for future self-realisation of future education managers.Approach: The work uses mathematical methods for testing the hypothesis of testing the readiness of education managers with verification of competency type.Findings: The novelty of the study is determined by what the authors are considering "the possibility of training a manager in accordance" including not only the standards for the provision of educational services to the population, but also the possibility of introducing world-class training standards. The authors show that the basis for such a development may be the readiness to work in a globalised environment. The dynamics of changes in the indicators of the levels of readiness for professional self-realization of students studying in the control and experimental groups from the first to the fourth year were compiled and recorded. The methodology of vocational training of students for the purpose of their self-realisation during training has been specified. The practical significance of the study is determined by the fact that integration with the global educational environment should be based on international standards for the provision of educational services. Conclusion: The results of this research can be useful and interesting to international readers, as the parameters of educational and methodological support have been developed and tested, which contains a set of situational exercises to form readiness for professional self-realisation for future education managers. Also, the conducted analysis indicated serious problems with the employment of university graduates both in the Republic of Kazakhstan and in the Republic of Lithuania.

Education reform at the science university and the new strategy for training science teachers

© 2016 by iSER, International Society of Educational Research.The urgency of the problem of designing a new strategy of teacher training due to the reform of education in universities: decrease of pedagogical disciplines, strengthening fundamental (subject) training, etc. The goal of the article lies in identification of the main components of the new strategy of teacher training. A leading approach to the study of this problem was personological. The result was a new model of teacher training. Undergraduate students are deepening their knowledge of the core subjects (be it Mathematics and Physics or Chemistry and Biology), while graduate students are making a choice: whether to be an engineer, researcher, scientist (which means keep deepening one’s knowledge) or be a teacher (which means master psychology, pedagogics, and the methodology of teaching a chosen discipline). The new approach has helped identify the indicators and determinants of pedagogical craftsmanship. The results of the study can be useful in designing new strategies for training teachers

The d'-Dibaryon in the Nonrelativistic Quark Model

The narrow peak recently found in various pionic double charge exchange (DCX) cross sections can be explained by the assumption of a universal resonance at 2065 MeV, called d'. We calculate the mass of a six-quark system with J^P=0^-, T=0 quantum numbers employing a cluster model and a shell model basis to diagonalize the nonrelativistic quark model Hamiltonian.Comment: 7 pages, Latex, 2 figures, invited talk at 6th Int.
