Flux cored arc welding (FCAW) is applied due to its remarkable results and advantages (high productivity, joint quality etc) in various fields (industrial construction, naval, chemistry, petrochemistry etc.). FCAW disadvantages, mainly the emission of pollutants, can be counteracted by their rigorous control and local forced ventilation in the production. Control measures that can be used for m...

Rapid India-Asia convergence has led to a major continental collision and formation of the Himalayas, the highest mountain range on Earth. Knowledge of the paleolatitude of the Kohistan-Ladakh Arc (KLA), an intermediate tectonic unit currently situated between the converging Indian and Eurasian continents in Western Himalaya, would constrain the tectonic history and dynamics of Himalayan orogen...

Clustering of arc volcanoes in subduction zones indicates along-arc variation in the physical condition of the underlying mantle where majority of arc magmas are generated. The sub-arc mantle is brought in from the back-arc largely by slab-driven mantle wedge flow. Dynamic processes in the back-arc, such as small-scale mantle convection, are likely to cause lateral variations in the back-arc ma...

Arc fault is the arc that may cause damage to the society. Arc is with high temperature and massive heat. If arc fault appears in the low voltage supply environment, it will lead to fire or disaster. So detection and protection of arc fault is essential. In order to prevent the damage of fault arc, a new apparatus named Arc Fault Circuit Interrupter (AFCI) has been proposed. In the paper, arc f...

We compared the efficiency and accuracy of full-arc and half-arc volumetric-modulated arc therapy (VMAT) delivery for maxillary cancer. Plans for gantry rotation angles of 360° and 180° (full-arc and half-arc VMAT) were created for six maxillary cancer cases with the Monaco treatment planning system, and delivered using an Elekta Synergy linear accelerator. Full-arc and half-arc VMAT were compa...

in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...
