Postnonclassical methodology and application of virtual reality technologies in social research.

The postnonclassical paradigm has increasingly become a conceptual basis for social research in various fields in an attempt to overcome the limitations of the classical and non-classical approaches. Subjects of social research activities require changes in the paradigm at all levels of research: from the statement of the problem to the elaboration of the appropriate methods and the analysis of the research data. The search for new research methods, technologies and techniques plays a crucial role in this process. One of the most promising methods that has rapidly developed in recent years is the technology of virtual reality (VR). This technology is being widely applied to both natural science and social science research. In this article, we examine the possibilities of using VR technology for the resolution of current tasks in social research from the perspective of the postnonclassical approach

Spin alignment of K∗(892)±K^*(892)^\pm mesons produced in neutron-carbon interactions

A new precise measurements of spin density matrix element $\rho_{00}$ of $K^*(892)^{\pm}$ mesons produced inclusively in neutron-carbon interactions at \~60 GeV have been carried out in the EXCHARM experiment at the Serpukhov accelerator. The values of $\rho_{00}$ obtained in the transversity frame are $0.424\pm0.011(stat)\pm0.018(sys)$ for $K^*(892)^+$ and $0.393\pm0.025(stat)\pm0.018(sys)$ for $K^*(892)^-$. Significant $P_T$ dependence of $\rho_{00}$ has been observed in $K^*(892)^+$ production.Comment: 8 pages, LaTeX, 3 eps figure

Review of Kaon Physics at CERN and in Europe

The Kaon physics program at CERN and in Europe will be presented. I will first give a short review of recent results form the NA48/2 and NA62 experiments, with special emphasis to the measurement of RK , the ratio of Kaon leptonic decays rates, K → eν and K → μν, using the full minimum bias data sample collected in 2007-2008. The main subject of the talk will be the study of the highly suppressed decay K → πνν. While its rate can be predicted with minimal theoretical uncertainty in the Standard Model (BR ∼ 8 × 10−11), the smallness of BR and the challenging experimental signature make it very difficult to measure. The branching ratio for this decay is thus a sensitive probe of the flavour sector of the SM. The aim of NA62 is the measurement of the K → πνν BR with ∼ 10% precision in two years of data taking. This will require the observation of 10K decays in the experiment's fiducial volume, as well as the use of high-performance systems for precision tracking, particle identification, and photon vetoing. These aspects of the experiment will also allow NA62 to carry out a rich program of searches for lepton flavour and/or number violating K decays. Data taking will start in October 2014. The physics prospects and the status of the construction and commissioning of the NA62 experiment will be presented. In the last part of the talk I will report on Kaon physics results and prospects from other experiments at CERN (e.g. LHCb) and in Europe (e.g. KLOE and KLOE-2) and briefly mention the status in US

The specialties of the behavior of green tourism’s consumer

Therere described different ways of determination of the definition needs and motives, also therere defined the factors which influenced on appearance of new types of tourism with the change of needs of consumers. Therere systemized the factors of internal (individual) and external characteristic for three segment groups of consumers of green tourism product. Therere determined, that tourist product has to connect with the requirements of consumers and to delight the customers, creating a healthy consumer

Analytical solution for the problem of the optimal single-row regular cutting into the triangles

В статье получена аналитическая формула для подсчета количества треугольников, которые можно разместить на прямоугольном листе заданных размеров, в случае если размещение является регулярным и однорядным. В качестве параметров, задающих треугольник, взяты радиус описанной окружности и углы, которые образуют векторы с началом в центре описанной окружности и концами в вершинах треугольника с одной из сторон листа. Полученные результаты использованы для тестирования программы, предназначенной для поиска оптимального раскроя и разработанной автором.У статті отримана аналітична формула для підрахунку кількості трикутників, які можна розмістити на прямокутному листі заданих розмірів, у випадку коли розміщення є регулярним і однорядним. У якості параметрів, що задають трикутник, обрано радіус описаного кола та кути, які утворюються векторами з початком у центрі описаного кола й кінцями у вершинах трикутника з однією зі сторін листа. Отримані результати використані для тестування розробленої автором програми, призначеної для пошуку оптимального розкрою.The formula for the calculation of the number of triangles which can be placed on a rectangular sheet of metal of the given sizes, for the regular single-row placing has been obtained. The triangle is determined by radius of the circumscribed circle and angles between the vectors, which join the center of this circle and the vertices of the triangle, and the side of the sheet. The obtained results have been used to test the program, developed by the author. This program deals with the finding of the optimal cutting

Photodynamic Therapy as Alternative Method of Treatment of Metastatic Ovarian Cancer with Many Recurrence: Case Report

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. Photodynamic therapy (PDT) is a minimally invasive therapeutic modality used for the treatment of a variety of cancers and benign diseases. The destruction of unwanted cells and tissues in PDT is achieved by the use of visible or near-infrared radiation to activate a light-absorbing compound (a photosensitizer), which, in the presence of molecular oxygen, leads to the production of singlet oxygen and other reactive oxygen species. Thus, the purpose of the report is to describe the clinical case of the effective use of intraoperative PDT as a method of treatment of a patient with metastatic cancer. Patient A, 59 years old, had ovarian cancer T3N1M0 stage III with peritoneal carcinomatosis. After intraoperative PDT (1.5 year) treatment, the progression of the process was not revealed by PET/CT. The results show that photodynamic therapy is one of the high efficiency methods of palliative treatment and it can be used for metastatic cancer. This technology should be included as a technique to the guidelines for the treatment of malignant tumors
