The characteristics of a DC vacuum arc in an axially symmetric magnetic field under contact opening are experimentally investigated. The magnetic field is formed with the help of the constant magnet placed on the side of the fixed contact. The magnet position is chosen so that near the working ...

The Luzon arc consists of a 1200 km chain of stratovolcanoes and volcanic necks stretching from Mindoro (13° N) to the Coastal Range of Taiwan (24° N). This study is concerned with three of the five major segments along the arc: the Northern Luzon, Babuyan, and Taiwan segments. The ...
Southeast Asian Bronze Age. We challenge this model by presenting a new chronological framework for Ban Chiang, which supports our model that the knowledge of bronze metallurgy reached Southeast Asia only in the late 2nd millennium BC, through contact with the states of the Yellow and Yangtze ...
