In the article research of influence of the technological loading is presented on stabilizing of the oscillating system. An oscillation separator is examined as an oscillating system that carries out force vibrations under the action of revolting force. By the feature of oscillation technological machines, such as oscillation separators, there is substantial influence of the technological loading that causes both quantitative and quality changes of motion of executive branch. In this case a concept of the added mass is unacceptable. The known researches do not decide the problem of the uneven specific loading of working surface of sieve in a complete measure. The growing productivity of modern separators envisages the increase of loading of working surface of vibrosieves. The process of vibrosieve separation is very sensible to the increase of loading, brings a division over to the decline of quality, needs more intensive office hours. The size of the initial specific loading substantially influences on the mutual location of areas of overload and underloading of working surface. The process of sifting becomes complicated at presence of areas of overload that results in the increase of thickness of layer and compression of mixture. Appearance of areas of underloading results in reduction of the use to the area of working surface. There is a decline of efficiency of process in these cases. For oscillation separators working in far superresonance modes at the comparatively small size of the technological loading influence of him is small felt. For resonant separators the insignificant sizes of the technological loading on an executive branch resulted in the substantial changes of parameters of his motion. For confirmation of this influence on the parameters of motion of executive branch special studies of oscillation separator were undertaken with the combined occasion. On the basis of results of researches of influence of the technological loading on the parameters of motion of oscillation technological machine drawn conclusion in relation to expediency of the use of the combined causative vibroagent for stabilizing system.

The regularities of specific loading distribution of loose mixture on the area of a working surface of the inclined tray are established in the work. The studies were performed on the experimental setup consisting of a storage hopper and inclined flat trays of different lengths. The material of the study was a grain mixture of winter wheat variety "Myronivska 30". The magnitude of the load was determined using a receiving device, which allowed to obtain the specific load distribution on the width and length of the tray and over time. The specific loading of the tray is uneven in the area of the working surface: the central section is overloaded, and the wall is underloaded. The largest deviations of the specific load at the inlet of the tray, but with length they decrease, approaching a uniform distribution. The specific load profile across the width of the tray is asymmetric and has a local extremum. As the tray length increases, at the certain initial speed and angle, the specific load decreases and the mixture flow slows down. With a constant supply of material from the hopper, there is a gradual accumulation of the mixture in the tray, compaction and growth of the layer, which leads to complete cessation of flow. Uneven loading of the tray occurs due to uneven supply of material from the storage hopper, in which the movement begins. The initial feed varies across the width of the tray and over time, and the nature of the specific load profile formed at the entrance to the tray is preserved for almost its entire length. The movement of the mixture flow in the inclined tray is non-stationary, the specific load varies significantly over the entire surface area and largely depends on the initial conditions of movement. The obtained regularities of specific loading on the working surface area of the tray can be used in the calculation of the modes of loose mixtures movement and substantiation of the equipment parameters for loading the working bodies of machines.

Executive privilege (EP) as a political tool has created a grey area of constitutional power between the legislative and executive branches. By focusing on the post-WWII political usage of executive privilege, this research utilizes a social learning perspective to examine the power dynamics between Congress and the president when it comes to government secrecy and public information. Social learning provides the framework to understand how the Cold War's creation of the modern American security state led to a paradigm shift in the executive branch. This shift altered the politics of the presidency and impacted relations with Congress through extensive use of EP and denial of congressional requests for information. When viewed through a social learning lens, the institutional politics surrounding the development of the Freedom of Information Act is intricately entwined with EP as a political power struggle of action-reaction between the executive and legislative branches. Using extensive archival research, this historical analysis examines the politics surrounding the modern use of executive privilege from Truman through Nixon as an action-reaction of checks on power from the president and Congress, where each learns and responds based on the others previous actions. The use of executive privilege led to the Freedom of Information Act showing how policy can serve as a congressional check on executive power, and how the politics surrounding this issue influence contemporary politics.

The subject of the research is a set of institutional institutions and organizational and managerial relations that effectively regulate the financial and investment environment in the EU countries, comparing them with Ukrainian realities.The goal of writing this article is to develop practical and scientific-methodicalrecommendations on how to increase the efficiency of using financial and investment potential based on the experience of EU countries. The methodology of thework-system-structural and comparative studies (to understand the logic of thefunctioning of institutions that form the investment environment and the mechanisms of their interaction); monographic analysis (in studying the problems ofattracting investors); historical and economic analysis (in assessing the state andprospects of the European, as well as the Ukrainian economy). Results of work -it is revealed that modern European regulators are aimed at forming a holisticinvestment and financial infrastructure and investment platform at the supranational level. It was proposed to carry out further liberalization of currency regulation in Ukraine in order to transform it into a convenient and efficient electronicautomated currency exchange system and introduce the integration of the domestic depository system into the international depositary clearing system Clearstream.It was noted that the financial and investment environment in Ukraine is blockedand domestic monopolies are interested in this, thanks to lobbying in the Verkhovna Rada of Ukraine and in the executive branch they have distorted financial,investment and currency legislation for their interests and needs. Conclusions-thepresence of a holistic investment and financial infrastructure in the EU countriesis due to the gradual convergence and unification of legislation at the nationallevel to the supranational level. In addition, it is reasonably high investment positions of Ireland in the world and it was proposed to use this experience to createa favorable financial and investment environment in Ukraine. Note that the formation of the financial and investment environment in Ukraine according to European standards is hampered by: oligarchic monopolies, which parasitizes mainly onnatural monopolies; government corruption; confusing and incomprehensible legislation for investors; high tax rates and tax administration system; instability ofthe banking system, the risks of hryvnia devaluation; the insecurity of landagrarian relations; as well as armed conflict in the east of Ukraine.

Economic Council

The world in its politico-economic aspects is run by policy-makers who have an academic background in law or public administration or other related social disciplines including economics. Only rarely would a majority of the policy-makers be trained in economics. In the making of economic policy, the basic choices before the policy-makers are political and they transcend the narrow concerns of economists regarding optimal use of resources. These considerations in no way downgrade the relevance of economic analysis in economic policy-making and for the training of policy-maker in economics. Policy-makers need economic council to understand fully the implications of alternative policy options. In this book, Wolfson attempts to educate policy-makers in the areas of public finance and development strategy. The analysis avoids technicalities and is kept to a simple level to make it understandable to civil servants, law-makers and members of the executive branch whom Wolfson refers to as policy-makers. Simplicity of analysis is not the only distinguishing mark of this book. Most other books on public finance are usually addressed to traditional public finance issues relating to both the revenue and expenditure sides of the budget and neglect an overall mix of issues dealing with the interaction of fiscal policy with economic development. Wolfson in this book explicitly deals with these issues.

The City

The latest special studies of the genus Synura in Russia were conducted in the 1970s. In the last decade, 14 new species of the genus were described based on molecular and morphological data. The total number of valid taxa of the genus has increased to 49. Only 18 taxa of Synura are known in Russia up to date, and the diver sity of the genus on this huge territory is strongly underestimated. Previous studies of the genus were focused mainly on large lakes or reservoirs. To reveal a more complete flora, it is necessary to include other habitats into account. Small urban rivers can be prospective habitats for interesting taxa including synuralean algae. Our study focuses on the taxonomic composition of the genus Synura in four small rivers in Nizhniy Novgorod (European Russia): Chyornaya, Levinka, Borzovka and Rzhavka. All the rivers flow in the city and fall under strong anthropogenic impact. The genus Synura was studied by means of transmission and scanning electron microscopy during 2011, 2012, 2014, 2015. In total, eight species and one form of Synura have been found: S. conopea, S. curtispina, S. echinulata, S. glabra, S. macropora, S. petersenii, S. spinosa f. spinosa, S. spinosa f. longispina, S. uvella. All nine taxa were observed in the river Chyornaya. Five taxa were found in the rivers Levinka, Borzovka and Rzhavka. One species (Synura conopea) is a new record to the flora of Russia. It was found in all studied rivers. Four taxa (S. conopea, S. glabra, S. macropora, S. spinosa f. longispina) are new records to the Middle Volga river basin.

One of the great paradoxes of the modern world is that India, the land that produced such major world religions as Buddhism Jainism is now torn apart by caste and communal violence. Pakistan and Sri Lanka, like India, face severe ethnic problems. Law and order are to be emphasized. Caste and community must be protected by the executive branch of the Indian Government. This bas been laid down in the rules framed by the legislative branch. When this is not done there is a breakdown. No one is safe and no group is secure. In India today this is clearly the case. This book by M. J. Akbar is a collection of 15 journalistic pieces, written for Akbar's newspaper and magazine, The Telegraph and Sunday over the last decade. Because it is journalism, the important "burning" issues are covered such as the Moradabad massacre in 1980, the slaughter of the Uttar Pradesh Harijans in 1981 and the ongoing Babri Masjid controversey. It is journalism, but the writing is of high quality and evocative: "It is early morning and a mist lies on the river, making the pre-dawn haze more blurred. A part of the Howrah Bridge looms through the gauze, like a picture deliberately created by a photographer in search of art. The fires are out." (p. 170) Akbar's material is hard, brittle, compelling stuff. He writes with the passion of the committed and his commitments are to secularism, to humanity, to the truth, as he sees it, on the ground. Here, a brief account of Dr. Akbar's cultural background seems appropriate: He was born in 1951 and has become the English-speaking voice of post-Midnight's Children of India. The significance of post 1947 independence as a dividing line is generally not fully appreciated. Missing is the literary, sentimental romanticism of the earlier Indian generation of writers. Don Moraes and Ved Mehta already appear as dated figures of the past. Their India is another country. In Akbar's background there is no punting on English rivers, laboring at Oxford intonations, getting drunk after the Oxford-Cambridge boat race nor leisurely reading of the English romantic poets on the banks of the Cam. Akbar lives in the urban nightmare of Calcutta and in his nostrils is the smell of burning flesh and rotting corpses. Missing, though he is aware of the loss, is the romantic vision of Nehru and the religious idealism of Gandhi. Akbar is an Indian writing with a white-hot pen for Indians of today's India ...
