Gaz kaynağı operasyonlarında sürecin süresini azaltmak için, kaynak bölgesinde düzgün akışkan özellikleri elde edebilmek için aleve giden gaz akısına doğrudan beslenebilen sıvı akışkanlar kullanılır. Bunların başında da bor türevi sıvılar gelir. Trimetil borat sıvısı kullanımında verimi artırılmakla birlikte iş riski de aynı oranda artırılmaktadır. Basınçlı kaplar prensibine göre çalışan düzene...

The Chah-Shur clay deposit is located in150 km southeast of Isfahan. Eocene igneous rocks ‎and Quaternary deposits cover the area. Eocene volcanic rocks include andesite and tuffs ‎which relating to magmatic activities of Urumieh-Dokhtar magmatic belt. Alteration of the ‎vitric and lithic tuff units has produced the clay deposit. Based on the petrographic studies, ‎the main minerals in tuff uni...

When the stagnation temperature of the combustion chamber or ambient air increases, the specific heats and their ratio do not remain constant any more, and start to vary with this temperature. The gas remains perfect, except, it will be calorically imperfect and thermally perfect. A new generalized form of the Prandtl Meyer function is developed, by adding the effect of variation of this temper...

For bounded linear operators defined on complex infinite-dimensional Banach space, H. Zariouh, in an article [1] introduced and studied the property (gaz). In this study, through techniques using local spectral theory of operators, we discover sufficient conditions that allow transfer (gaz) from two tensor factors T S to their product T⊗S. The stability under perturbations is also investigated....
