Effects Of The Upwind Spanwise Heterogeneous Terrain On The Wind Resource Distribution, Haosen H.A. Xu, Tianxiang Yu, Raúl Bayoán Cal, Xiaowei Zhu

Mechanical and Materials Engineering Faculty Publications and Presentations

Wind energy has become increasingly crucial among renewable energy resources, and as the prerequisite for effective wind energy utilization, accurate wind resource assessments are hence prominent. Topography significantly affects near-surface wind fields and is thus an essential factor to be considered for wind resource assessment. However, few studies have addressed the wind resource distribution downwind of spanwise-heterogeneous terrains, which are frequently encountered in both natural and urban environments. To fill this gap, large eddy simulations were performed to investigate wind distributions over a uniform terrain downwind of terrains featuring spanwise-alternating strips of low and high surface roughness, and the high …

The Religious Policy Of The Russian Empire In The Captured Territories Of The Polish-Lithuanian Commonwealth (On The Example Of The Volyn Province At The End Of The 18th-The First Half Of The 19th Century), Andrii Shevchuk, Oksana Markevych

The article investigates the peculiarities of the implementation of the religious policy of the Russian Empire in the territories that were captured as a result of the partitions of the Polish-Lithuanian Commonwealth, on the example of the Volyn province in the late eighteenth and early nineteenth centuries. The role of local administration, in particular governors, in the implementation of the imperial confessional policy and the mechanisms of integration of the Orthodox Church into the state apparatus are analyzed. It is established that after the November Uprising of 1830-1831, religious policy was radicalized, which manifested itself in the forced liquidation of …

Operation “Prophets” Or Integration Of Pentecostals Into The Structures Of The Aucecb By The Nkgb-Kgb, Александр Коротаев

Occasional Papers on Religion in Eastern Europe

The purpose of this article is to expose the work of the Soviet special services, which was directly aimed at incorporating the Pentecostals of the USSR into the structure of the All-Union Council of Evangelical Christians and Baptists (AUCEC&B). It reveals the mechanisms, forms, and methods used by the Soviet special services (NKGB-KGB) to achieve this incorporation. It has been proven that this process was purely coercive in nature and was directly intended to eliminate Pentecostals as a denomination, using Evangelical Christians and Baptists (ECB) as a means to that end.

Transformations Of Religious Consciousness Of Ukrainians In The 1990s, Bogdan Sulyatytskyy

Occasional Papers on Religion in Eastern Europe

The article analyses the transformation of religious consciousness of Ukrainians during the first decade of the post-Soviet period. It identifies the socio-cultural, economic and political factors that influenced the formation of a new attitude of Ukrainian citizens towards religion. It is noted that in the 1990s, a distinction between ethnic and religious identity occurred in the religious consciousness of Ukrainians, which contributed to the rapid transformation of Ukraine from a historically Christian (mainly Orthodox) country into a poly-confessional one. During this period, new syncretic mental structures were formed, radically different from the established traditional religious ones, in which elements of …
