It is an unsolved mystery that the rotation velocity of a galactic disc is same at any radial distances.The presence of dark matter is expected, but not observed.Here we propose a novel scheme for the evolution of the initial cosmic energy to current galaxies.According to the energy circulation theory, which we previously reported, the fundamental

This article offers a review of the evidence that give insight into the religious ideas and cultic practices of soldiers and officers in the garrison of Tyras.In the southern part of the citadel, two structures were discovered, identified by the researchers as temples.A votive altar dedicated by a military sailor to the god with an epithet Invicto

This paper addresses the concept and development of an intelligent education system in concurrent engineering environment based on object oriented technique for conventional processes such as drilling, reaming, boring, slot drilling, end milling, tapping, etc.and unconventional processes such as electrochemical machining (ECM), electro-discharge ma

Non-thermal plasma as a tool in chemical reaction engineering has been studied for many years.The temperature of electrons in non-thermal plasma far exceeds other particles, which leads to its high efficiency.Besides the well-studied destruction of volatile organic compounds (VOCs), the reaction environment generated by non-thermal plasma is also s
