We have reviewed the known data about mechanisms, conditions, reasons, and characteristics of rebound, coagulation, and explosive disintegration of drops in gas-vapor-droplet streams. The three main factors of altering a direction of motion, a velocity, a size and a concentration of droplets in a gaseous stream have been highlighted. Among of them are the thermal factor (heating and evaporation of drops), the aerodynamic factor (acceleration, reverse motion, and deceleration of drops due to their entrainment by gaseous stream), the dynamic factor (change in size, velocity, and direction of motion of drops after their collision). We have generalized the findings obtained by various authors in experiments with two drops, little group of drops, and aerosol. In addition, we have reviewed the published results about the fields of velocities and motion trajectories of drops in a flow, about the change in size and concentration of drops due to rebound, coagulation, disintegration (i.e. the complete destruction of the parent drops and the detachment of the liquid fragments of different size and volume from the surface).

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.

Anti Jewish

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.

Main Factors

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.

Abstract The paper presents the summary of research on polymer melt particle motion trajectories in a disc zone of a screw-disk extruder. We analysed two models of its structure, different in levels of taken simplifications. The analysis includes computer simulations of material particle flow and results of experimental tests to determine the properties of the resultant extrudate. Analysis of the results shows that the motion of melt in the disk zone of a screw-disk extruder is a superposition of pressure and dragged streams. The observed trajectories of polymer particles and relations of mechanical properties and elongation of the molecular chain proved the presence of a stretching effect on polymer molecular chains.

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.

Subject. This article examines the issues related to changes in reproduction capacity and heterogeneity of the development of Russian regions. Objectives. The article aims to assess regional differentiation and investigate the main factors influencing the uneven development of the areas. Methods. For the study, we used the methods of comparative and correlation analyses. Results. The article identifies groups of leading and lagging Russian regions and assesses the possibility of convergence of Russian regions according to the analyzed indicators, such as GRP, GRP per capita, and the output of industry. Conclusions. The results obtained can be used when preparing strategic policy documents, spatial development programmes and concepts. The observed heterogeneity suggests that the regions maintain their positions throughout the research period.
