In fire resistant design traditional method based on experiment is being replaced by method based on calculation.in this paper Damage mechanics is applied to calculate and analyze the process of damage and failure of structures at high temperature through solving jointly the closed equations composed of the thermal damage evolving equation based on the residual strength, heat conduction equations, equilibrium equations, geometry equations and physics equations. An example of a truss is given to illustrate the calculation of thermal damages and stresses at high temperature. The results suggest, the bearing capacity at high temperature is influenced by these three main factors: thermal damage resulted from the elevated temperature, the thermal stresses and the original load. This provides a new research method for the modern fire-resistant design based on calculation and can be developed and applied in the numerical simulation of the process of damage and failure of the integrated structures.

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

In the early years following World War II, the Lublin region was one of the most important centres of Jewish life. At the same time, during 1944-1946 it was the scene of anti-Jewish incidents: from anti-Semitic propaganda, accusation of ritual murder, economic boycott, to cases of individual or collective murder. The wave of anti-Jewish that lasted until autumn of 1946 resulted in a lengthy and, no doubt incomplete, list of 118 murdered Jews. Escalating anti-Jewish violence in the immediate post-war years was one of the main factors, albeit not the only one, to affect the demography (mass emigration) and the socio-political condition of the Jewish population in the Lublin region

It has been known that both in the world and in Turkey a continuous change has been experienced in the provision of health services in recent years. In this sense by adopting the customer(client) focused approach of either public or private sector hospitals; it has been seen that they are in the struggle for presenting a right, fast, trustuble, comfy service. The purpose of this research is to measure the satisfaction degree, expectations and perceptions of the patients in Karabük State Hospital through comparison. In this context, the patient satisfaction scale which has been developed as a result of literature review has been used and by this scale it has been tried to measure the satisfaction levels of the patients in terms of material and human factors which are the two main factors of the service that was presented. In the study, with the scales of Servqual and 0-100 Points together, in the part of the analysis MANOVA have been used. The expectations and the perceptions of the patient has been compared first by generally and then by separating to different groups according to the various criterias and in thisway it has been tried to be measured their satisfaction levels. According to the results that were obtained, although, the satisfaction levels of the patients who have taken service from Karabük State Hospital are high in terms of thedoctors and the nurses; it has been reached to the result that their satisfaction levels are low in terms of the materials that have been used at the presenting of the service and the management.

One of the options being considered for the disposal of radioactive waste is deep burial in crystalline rocks such as granite. It is generally recognised that in such rocks groundwater flows mainly through the fracture networks so that these will be the “highways” for the return of radionuclides to the biosphere. The main factors retarding the radionuclide transport have been considered to be the slow water movement in the fissures over the long distances involved together with sorption both in man-made barriers surrounding the waste, and onto rock surfaces and degradation products in the fissures.

ABSTRACTThe geographic position, astronomic factors (e.g. the Earth’s maximum distance from the Sun during winter), ice cover and altitude are the main factors affecting the climate of the Antarctic, which is the coldest place on Earth. Parts of Antarctica are facing the most rapid rates of anthropogenic climate change currently seen on the planet. Climate changes are occurring throughout Antarctica, affecting three major groups of environmental variables of considerable biological significance: temperature, water, UV-B radiation.Low diversity ecosystems are expected to be more vulnerable to global changes than high diversity ecosystems

Subject. This article explores the key liquidity figures of the twenty five largest public oil and gas companies between 2006 and 2018. Objectives. The article aims to determine the current values of the key liquidity figures of the largest public oil and gas companies, identify key trends in their changes within the study period, and identify the factors that have caused these changes. Methods. For the study, I used comparative, and financial and economic analyses, and generalization. Results. Based on a comprehensive analysis of the twenty five oil and gas companies' annual reports, the article identifies trends in the changes in the key liquidity indexes in the industry's public sector, and establishes the main factors that affected these changes. Conclusions and Relevance. The largest public oil and gas companies are able to maintain their own liquidity in times of crisis, even. The industry pays the most attention to increasing the instant liquidity ratios. The results of the study can be used to evaluate, forecast, and develop measures to enhance the liquidity of public oil and gas companies.
