The christians of the Middle East and the role of their “conspiracy” in the Archipelago expedition of the Russian navy in 1769–1774

The history of the fi rst military and political contacts between Russia and the Arab world has long been ignored by Russian orientalists. The reason was the unwillingness to introduce the “imperialistic” component to the untainted history of Soviet-Arabic relations. Due to the studies of the recent past, we have a relatively full picture of both the course of events of 1770‒1774 and changes in the political agenda that urged local rules to enter a union with Russia. However, the reasons that underlay the alliance of Near Eastern rulers with a Christan state cannot be reduced to just basic political and economical factors. A prominent role was also played by the religious and ideological component, which is described in the article

Dynamic Modeling of Lift Hoisting Mechanism Block Pulley

AbstractThe mathematical model of loaded block pulley trolley movement was developed based on Lagrange equation of the second genus. The differential equations of loaded trolley motion were given along with the relations for viscoelastic block pulley characteristics based on empirical observations. It was shown that the modeling block pulley dynamics could be substantially simplified by means of universal program complexes when considering the mass variation and the rope rigidity of block pulley negligible by changing its length.It was demonstrated that the loaded block pulley model could be geared as a subsystem for the computer dynamic model of lifting crane, when executing the axial force of upper block pulley, the movement of exit rope section and the rope tension force at this section by means of subsystem output parameters.The example of trolley motion start model was given for the simultaneous load lifting with at a constant speed with the use of three-mass model
