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...

کارکرد مطلوب عملیات سازمان های آتش نشانی به تعداد و نوع تجهیزات و امکانات بستگی دارد. بدون وجود تجهیزات و امکانات مناسب چه از نظر کمّی و چه از نظر کیفی، سازمان آتش نشانی قادر نخواهد بود مسئولیت ها وکارکرد های خود را به نحو احسن انجام دهد. بنابراین اطلاع از وضعیت تجهیزات و امکانات در کلیه ابعاد کمک بسیاری به پیش بینی سطح ارائه خدمات مورد نیاز در هنگام وقوع بحران می کند. بدین منظور این پژوهش به بر...

In a geometric context, two objects are “visible” to each other if there is a line segment connecting them that does not cross any obstacles. Over 500 papers have been published on aspects of visibility in computational geometry in the last 40 years. The research can be broadly classified as primarily focused on combinatorial issues, or primarily focused on algorithms. We partition the combinat...

Bronchiolitis, a disease primarily of the first 2 years of life charac­ terized by signs and symptoms of obstructive airway disease, is caused most commonly by viruses. Approximately 2% to 3% of infants in the first 12 months of life are hospitalized with bron­ chiolitis, accounting for approximately 125,000 hospitalizations and 200 to 500 deaths annually in the United States. Data from the Cen...

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...

Abstract In this study, we investigate the age and geochemical variability of volcanic arc rocks found in Chinese, Kyrgyz, Tajik North Pamir Central Asia. New geochronological data together with compiled from literature give a holistic view an early to mid-Carboniferous intraoceanic preserved northeastern Pamir. This complex involves continental slivers its western reaches transforms into Cordi...
