This book summarizes the theoretical and experimental studies confirming the concept of the liquid-crystalline nature of boundary lubrication in synovial joints. It is shown that cholesteric liquid crystals in the synovial liquid play a significant role in the mechanism of intra-articular friction reduction. The results of structural, rheological and tribological research of the creation of artificial synovial liquids containing cholesteric liquid crystals in natural synovial liquids are described. These liquid crystals reproduce the lubrication properties of natural synovia and provide a high chondroprotective efficiency. They were tested in osteoarthritis models and in clinical practice.
Now updated with new facts, and abridged for use in Soviet history courses, this gripping book assembles top-secret Soviet documents, translated into English, from the era of Stalin's purges. The dossiers, police reports, private letters, secret transcripts, and other documents expose the hidden inner workings of the Communist Party and the dark inhumanity of the purge process."[book cover].
Based on meticulous research in previously unavailable documents in the Soviet archives, this compelling book illuminates the secret inner mechanisms of power in the Soviet Union during the years when Stalin established his notorious dictatorship. Oleg V. Khlevniuk focuses on the top organ in Soviet Russia's political hierarchy of the 1930s--the Political Bureau of the Central Committee of the Communist Party--and on the political and interpersonal dynamics that weakened its collective leadership and enabled Stalin's rise. Khlevniuk's unparalleled research challenges existing theories of the workings of the Politburo and uncovers many new findings regarding the nature of alliances among Politburo members, Sergei Kirov's murder, the implementation of the Great Terror, and much more. The author analyzes Stalin's mechanisms of generating and retaining power and presents a new understanding, unmatched in texture and depth, of the highest tiers of the Communist Party in a crucial era of Soviet history.
