    ON STABILITY OF THE OIL DISPLACEMENT FRONT UNDER CONDITIONS OF THERMOGAS IMPACT ON THE OIL BEARING LAYER by K. V. Dobrego

    Published 2016-03-01
    “…The mechanisms of suppression or compensation of the front perturbation growth are as follows: the crude oil viscosity reduction and increase of that of the displacement agent, the displacement agent compressibility increase, increase of the thermogas impact heat-front width in the first instance at the expense of the temperature growth and alteration in the chemism (low temperature catalysts utilization, etc.), reduction in speed of the front propagation and/or correspondingly of the displacement agent feed. …”

    From disagreement to rupture: the Soviet-Albanian conflict of 1960-1961 by K. K. Khudoley

    Published 2024-04-01
    “…Key findings include: 1) The conflict's primary catalysts were the divergent socialist models adopted by the USSR and Albania, coupled with the disparity in interests between the superpower and the bloc's smallest member; 2) The PLA's reluctance to conform to Soviet-style reforms was construed in Moscow as a challenge to the CPSU's hegemony within the global communist movement, while the PLA leadership viewed them as encroachments on its authority; 3) Disagreements pervaded all spheres, with ideology assuming heightened significance compared to conflicts with Yugoslavia; 4) External influences on the conflict's trajectory were marginal, with developments driven by internal dynamics, including Tirana's increasing alienation from the CPSU and the catalytic effect of deteriorating Soviet-Chinese relations; Western powers monitored events closely but refrained from direct intervention; 5) While objective factors underpinned the Soviet-Albanian discord, subjective elements were of secondary importance, yet pivotal in precipitating the conflict's acrimonious turn.…”
