Cold rolled steel structures have been known since the mid-19th century in the United States and Great Britain. Despite the advances in the development of cold-rolled structures, the level of their use was lower than that of hot-rolled structures. A significant factor that influenced this imbalance in application was the fact that there were no regulations. Into different countries of the world have their own national regulations for the calculation of cold-rolled steel structures, which have many controversies. In the European group includes the norms of the countries of the European Union, Great Britain, Hong Kong, Ukraine, Belarus, Kazakhstan; American group - the United States of America, Canada, Mexico, Australia, New Zealand, Brazil, Chile, Egypt. The regulations of such large countries as China, India and Russia have their own characteristics. The article presents the results of a technical survey of the load-bearing structures of the canopy. The survey was carried out to determine the bearing capacity of the roof load-bearing structures in relation to the location of the solar panels on the roof of the building. The construction of buildings and their structural parts from light steel thin-walled structures (profiles) is carried out in the form of light frames, the frames of which are successively connected into spatial systems. A new lightweight roof covering made of profiled sheet and a frame structure made of cold-rolled P-profile and C-profile elements for roofing and installation of solar panels are proposed. Such a coating is the most industrialized, easily and quickly erected. The analysis of constructive options for the effective placement of the profile of cold-rolled elements and joints of the frame and reinforced concrete run of the coating is carried out. The design of the frame was carried out in the software package " Лира САПР 2013" . The results of the work carried out served to draw up recommendations for restoring the properties of the load-bearing structures of the canopy, the development of design estimates and implementations into construction practice during the reconstruction of the canopy.

The so-called “long 19th century”, from the French Revolution to the First World War, ranks as the crucial phase in the genesis of the modern world. In the Western countries this period was characterized by the differentiation of the public and the private spheres, the birth of the modern bureaucratic state and the delegitimation of early modern practices such as clientelism and patronage. All these fundamental changes are, among other things, usually considered important preconditions for the modern perception of corruption.This paper will concentrate on this crucial phase by means of a comparative analysis of debates in France, Great Britain and the United States, with the aim to elucidate the motives for major anti-corruption movements. The questions are: who fights against corruption and what are the reasons for doing so? I will argue that these concerns were often very different and sometimes accidental. Furthermore, an analysis of political corruption may reveal differences between the political cultures in the countries in question. Thus, the history of corruption serves as a sensor which enables a specific perspective on politics. By taking this question as a starting point the focus is narrowed to political corruption and the debates about corruption, while petty bribery on the part of minor civilservants, as well as the actual practice in the case of extensive political corruption, is left aside.

This is a book about terrorism, weapons, and diplomacy in the interwar years between the First and Second World Wars. It charts the convergence of the manufacture and trade of arms; diplomacy among the Great Powers and the domestic politics within them; the rise of national liberation and independence movements; and the burgeoning concept and early institutions of international counterterrorism. Key themes include: a transformation in meaning and practice of terrorism; the inability of Great Powers—namely, Great Britain, the United States, France—to harmonize perceptions of interest and the pursuit of common interests; the establishment of the tools and infrastructure of modern intelligence—including the U.S.-U.K. cooperation that would evolve into the Five Eyes intelligence alliance; and the nature of peacetime in the absence of major wars. Particular emphasis is given to British attempts to quell revolutionary nationalist movements in India and elsewhere in its empire, and to the Great Powers’ combined efforts to counter the activities of the Communist International. The facilitating roles of the Paris Peace Conference and League of Nations are explored here, in the context of the Arms Traffic Convention of 1919, the Arms Traffic Conference of 1925, and the 1937 Terrorism Convention.
