Human Rights Situation in Ukraine
The Ministry of Foreign Affairs of the Russian Federation 9.12.20 О ситуации с правами человека на Украине Unofficial translation HUMAN RIGHTS SITUATION IN UKRAINE Report of the Ministry of Foreign Affairs of the Russian Federation Moscow 2020 Table of Contents 1. Manifestations of neo-Nazism, glorification of former Nazis and collaborationists, as well as the spread of racism and xenophobia 2. Restrictions on media activities (censorship, pressure, harassment of journalists) 3. Persecution of national minorities 4. Discrimination of national minorities in the area of education and the use of their language 5. Human rights violations by Ukrainian law enforcement agencies 6. Discrimination against believers and the clergy of the canonical Ukrainian Orthodox Church 7. Violations of social and economic rights of the population of South-Eastern Ukraine This report is a further effort by the Ministry to draw attention of the international community to a grim human rights situation in Ukraine with no signs of its improvement at this point. On the contrary, there continue systemic violations of basic human rights and freedoms. There is no respect for the right to freedom and personal integrity. There have been multiple instances of unlawful detention, as well as tortures, intimidation, and ill-treatment, including with a view to extorting confessions from detainees. Under the pretext of combating "Russian aggression" and separatism, there continue repressions against political opponents, independent journalists and media companies, as well as members of civil society organizations unsuitable to authorities. To that end, the Ukrainian government actively engages radical nationalist groups. Undue restrictions apply to the rights of internally displaced persons, Russian speaking citizens and national minorities. -
The Korean War: a Historical Dictionary'
H-War Werrell on Edwards, 'The Korean War: A Historical Dictionary' Review published on Tuesday, February 1, 2005 Paul M. Edwards. The Korean War: A Historical Dictionary. Lanham: Scarecrow Press, 2003. xxxix + 367 pp. $75.00 (cloth), ISBN 978-0-8108-4479-7. Reviewed by Kenneth Werrell (Radford University) Published on H-War (February, 2005) Broad and Useful: An Encyclopedia on the Korean War It is clearly an understatement to write that Paul M. Edwards is a prolific author, for few authors have thirty or so books to their credit. These include four novels, thirteen books on religion and philosophy, and this, his tenth volume on the Korean War. His works on the Korean War include a guide to films, a documentary history, four bibliographies, a book of poetry, a monograph on how the war is remembered, a narrative history, and now this historical dictionary--or perhaps more clearly, this historical encyclopedia.[1] Edwards is the creator and director of The Center for the Study of the Korean War, which is located at Graceland University in Independence, Missouri. It was established in 1989 by Edwards after his retirement from Temple School where he taught philosophy and religion. He also was dean of the graduate school at Park College, and it might be added, served in the army in Korea during the Korean War. Any scholarly work on the Korean War is most welcome as this conflict has been completely overshadowed, first by World War II, and more recently by the Vietnam War. While it may be a cliché to call this "The Forgotten War," this is in fact an accurate description. -

On the national level it was a war between two halves of one people, arbitrarily separated by powers much greater than themselves, fighting for the reunification of their land – hence the northern Democratic People’s Republic of Korea’s (DPRK) invasion of the southern Republic of Korea (ROK) beginning June 25, 1950. At the regional level it was a campaign between the US-led coalition of western democracies fighting under the banner of the United Nations (UN) and the Communist partnership of the USSR and the newly-formed (in December 1949) People’s Republic of China (PRC). Once the DPRK’s Korean People’s Army (KPA) was forcibly ejected from South Korea by UN Command (UNC) forces, the PRC became primarily responsible for their side’s ground operations, while the USSR – because the PRC’s neophyte air force was not yet prepared for combat – provided air cover. This contest, pitting three Communist countries against the US-led UNC, was fought – bitterly, but with limited local objectives by both sides – within the global context of the Cold War, an ideological struggle that was just getting into its stride following the Berlin Crisis, the formation of NATO and the utter defeat of the Chinese Nationalist Kuomintang (KMT) during the previous two years. -

Some had been captured in Spain during the Civil War and sent back to the Soviet Union, while others were bought from the Germans following the signing of the infamous non-aggression pact between the two countries in August 1939. Having studied the Luftwaffe’s principal fighter, the Messerschmitt Bf 109E, and compared its flight data with the then new MiG-3, Yak-1 and LaGG-3, both the leadership of the VVS-KA and senior aircraft designers came to the conclusion in early 1941 that Soviet fighters had at last attained parity with their western European equivalents. However, in the immediate aftermath of the launching of Operation Barbarossa on 22 June 1941, it quickly became apparent that the E-model’s replacement, the Bf 109F, was clearly superior to all Russian fighters then in frontline service. For example, the ‘Friedrich’ was faster than all three new Soviet fighters up to an altitude of 16,500ft – fighting rarely occurred at higher altitudes on the Eastern Front. -

Determining the influence of the geometric parameters of a spiroid WD on aerodynamic wing characteristics, however, remains an understudied field. In our study, we investigated the influence of the following geometrical parameters on wing aerodynamic characteristics with WD: area, radius, camber angle, constriction, and pitch of the spiroid. We found that the positive effect of the WD is present at a relative radius r > 0.05, as well as with an increase in the lift coefficient CL as a result of an increase in the proportion of inductive resistance. For example, with the Reynolds number Re = 2.1×10 5 for a rectangular wing with an aspect ratio θ = 5.12 equipped with a spiroid WD with r =0.15 the quality gain is almost 10% at CL = 0.5, and at CL = 0.7 is almost 20% and at CL = 0.7 – almost 20% compared to a wing without WD. -
