Main factors affecting the long-term stability of microwave oscillator frequency are discussed in this paper. External factors affect the signal frequency at the output of any actual source, causing it to continuously change over time. Long-term frequency instability could be attributed to aging of the material. So, it is necessary to take special environmental factors into account, when designing microwave oscillators for space electronic equipment.

The operability of the bearing assembly, which ensures the operation of the turbocharger at different speeds of its rotor, determines the reliability of the turbocharger as a whole. In this regard, the condition of the turbocharger bearing assembly determines the performance of the entire turbocharger. The purpose of the research is to justify the parameter that determines the performance of the turbocharger and a comparative assessment of changes in the state of turbochargers with a standard lubrication system and when using individual bearing assembly lubrication systems. The main factors affecting the state of the turbocharger bearing assembly, and hence the length of the rotor rotation by inertia after the engine stops, are considered to be: the increase in the clearance in the bearing assembly, the speed of rotation of the turbocharger rotor before the engine stops, and the time of pressure drop in the bearing assembly to zero after the engine stops. To obtain dependences describing the effect of the gap in the turbocharger bearing, the time of pressure drop in its lubrication system after the engine stops, and the change in the duration of rotation of the turbocharger rotor by inertia in dynamics, we conducted experimental studies. The experiment involved vehicles with a standard lubrication system and with an individual lubrication system for the turbocharger bearing assembly. The data was sample along the main diagonal of the matrix of experimental indicators. The dependences of the effect of the gap and the time of pressure drop in the bearing assembly on the duration of rotation of the rotor of the turbocharger by inertia after stopping the engine, at the speed of rotation of the rotor before stopping the engine 10000, 25000 and 40000 min-1 are obtained. A comparative analysis of this indicator is given for turbochargers with a standard and individual lubrication system of the bearing assembly, which shows that the duration of rotation of the rotor by inertia increases from 45 s (standard lubrication mode) to 90 s (with an individual lubrication system). This gives us reason to believe that the wear rate of the bearing will decrease by half during operation

Abstract Economic resilience is defined as the ability of the economy to overcome the negative external shocks. It depends on macroeconomic factors and internal conditions of the country or region. Macroeconomic factors include fiscal policy, economic and monetary policy. Among the internal factors economic structure, the level of restructuring and modernization of enterprises, competitiveness and innovation should be mentioned. Among the important soft internal factors level of human capital, including entrepreneurship can be distinguished. The aim of the paper is to present the issue of economic resilience and explain what are the main factors constituting resilience of Pomorskie region (voivodship) in Poland. To achieve this aim, authors first give a theoretical introduction regarding the economic resilience concept as well as describe the methods of economic resilience measurement. Secondly the macroeconomic, external factors affecting the analysed region are discussed. Next the authors measure resilience of Pomorskie region basing on statistical data and compare the resilience of Pomorskie region with other regions in Poland. At the and the authors, basing on extensive interviews with experts, representatives of regional business and administration, attempt to explain why Pomorskie region is more resilient to economic crises than other Polish regions. In this part Pomorskie economy structure is presented too.

The article is devoted to the study of the national identity of the Republic of Kazakhstan. The article analyzes the main factors affecting the emerging national identity of the modern Republic of Kazakhstan. Thus, we study a complex process involving many stages, it is obvious only when the ratio of two different identities: civil and national, the most important part of the process of integration of which is the exchange of its elements. The article also provides an assessment of the effectiveness of the state strategy in this area, describes the presence of two main strategies of national-state construction and, accordingly, the dominant models of national identity. The first strategy is aimed at the formation of a single Kazakh nation from a multi-ethnic society on the basis of common citizenship, the second strategy is related to the national identity of the Kazakhs themselves. The prerequisites for the formation of an integral model of national identity as the Foundation for further modernization of society on the basis of civil consolidation and political stability of society, allowing to ensure the priorities of state-building and socio-economic development, preservation of civil peace and spiritual harmony, strengthening of the international authority of the state.

Oil and its refinery products have always been the most important source of energy for modern society, and, therefore, one cannot imagine the life of mankind in any field of its activity without this resource. Energy, military defense, transport, agriculture, domestic needs of the population, the economy of the country are directly dependent on oil and its prices, it plays an extremely important role for Russia in particular, since it is the main revenue item for the state, therefore, forecasting oil prices is a primary task. The purpose of the article is to forecast the prices for this resource for April-August 2018 on the basis of the neural network model use as one of the ways to implement artificial intelligence. Oil prices have been chosen as the object of forecasting, and the subject is the dynamics of oil prices. The choice of the object and the subject of forecasting was conditioned by the fact that the price of oil is one of the main factors affecting the state and pace of development of the domestic economy, and primarily GDP. The pricing of many types of oil is determined by the price of the Brent crude oil reference mark, including the cost of three out of five Russian export brands: Urals, Siberian Light and REBCO, calculated on the basis of Brent prices.

In Slovenia low and medium production systems are prevalent in sheep breeding. The rearing technology depends on a large number of factors. The main factors affecting the choice of rearing technology are sheep breed, local conditions, season of mating and weaning time. In the present study the rearing technology in sheep breeding was analyzed. This analysis included the results of 293 questionnaires from sheep breeders of autochthonous Jezersko-Solcava and Improved Jezersko-Solcava breed. Data were subjected to the frequency analysis, using the FREQ procedure of the SAS Statistical Software (1990). The population size in the flocks of these breeders was mostly from 5 to 50 animals (73.3%). The lambing system is year-round (80%) and seasonal (7.5%). The wanted litter size of 47% of breeders is just one live born lamb. Breeders weaned their lambs at 60-90 days of age or even later. Lambs stayed with their mothers almost till the end of lactation (16-20 weeks) or till the sale to the market when they weighted 30-35 kg. Early spring and summer born lambs stayed with their mothers on the pastures with no supplement. Winter born lambs stayed with their mothers in the stable, fed by hay and supplement (cereals or commercial concentrate). The rearing technology used by Slovenian sheep breeders is sustainable and gives the opportunity for conservation of autochthonous breeds in the original environment.

Main Factors

There are two main factors in deciding ticket price in transportation providers. They are the direct and indirect costs. Other than that, there are also other external factors affecting the ticket price, which are distance, load factor, expected profit and the managerial decision to increase and/or decrease the ticket selling price.  All of these components are calculated until finally come up to final ticket price. The research is conducted to analyse the factors influencing the ticket price and to find out how the ticket price is calculated. The result shows that the research object has properly calculating the ticket selling price, but still can not define a break event point. This is important if the company wishes to achieve its objectives, one of which is maximum profit. The goal in calculation of break event point is to determine the uncertain figure by managerial policy on estimated profit, load factor, and final rounding offs.

This study considers the changes that may affect the structure of the state in Syria during the post-conflict phase by assessing interactions between state and non-state actors in the lead-up to the reassertion of central control over southern Syria in 2018. These interactions took place at several overlapping levels (state/non-state, state/foreign, non-state/foreign). The study analyzes the interaction between the Syrian regime and ten different actors, arguing that the nature and trajectory of interactions between state and non-state actors were the result of the interaction of two basic categories of factors: internal (characteristics of actors) and external (structural). The main factors affecting how the regime approached specific actors were their political leanings and whether they enjoyed international support. Other factors were less influential on regime policy, i.e., the extent to which the state was able to fill the gap left behind by an actor's withdrawal or the national/transnational character of that actor's political project.
