The Lake Siah magnetite ± apatite deposit is situated in the northeastern of Bafq and Central Iran tectonic zone. The host rock of deposit is composed from lower Cambrian volcano-sedimentary sequence that has exposed as caldera complex. The iron mineralization is as massive ore and includes magnetite and hematite which form with apatite, quartz and calcite gangue minerals. Based on fluid inclus...
in this paper, we study the existence of generalized solutions for the infinite dimensional nonlinear stochastic differential inclusions $dx(t) in f(t,x(t))dt +g(t,x(t))dw_t$ in which the multifunction $f$ is semimonotone and hemicontinuous and the operator-valued multifunction $g$ satisfies a lipschitz condition. we define the it^{o} stochastic integral of operator set-valued stochastic pr...
In the nonmetallic state of the organic superconductor k-~BEDT-TTF)2Cu@N(CN)2#Br synthesized with deuterated BEDT-TTF molecule, an angle-dependent electron spin resonance signal below 6–8 K was found. This is interpreted in terms of an antiferromagnetic resonance. The signal was found only when the sample was rapidly cooled, corresponding to the characteristics in that the present salt stays cl...
Abstract Mineral inclusions within native gold are features of lode occurrences that preserved in detrital particles. Inclusion assemblages populations particles placers from specific localities revealed through inspection polished sections, and assimilation robust data sets permits reconstruction the source mineralogy. differ considerably according to deposit type, various approaches have been...
microalloyed s355n steel plates are extensively used in bridge and high-rise building structures. one ofthe factors affecting the mechanical properties is the size and morphology of inclusions. in this research,microalloyed s355n steel plates with different sizes of inclusions were examined. one contained longmanganese sulfide inclusions (li material) and the other had short ones (si material)....
The Kuh Zar Au-Cu deposit is located about 100 km southeast of Damaghan city. Structurally, this area is part of the Alborz Magmatic Assemblage (AMA). The oldest rock units in the Firuzeh-Gheychi area consists of syenogranite and tourmaline biotite granodiorite units. These units were intruded by quartz monzonite porphyry stocks. Pyroxene diorite porphyry and hornblende diorite porphyry are you...
The main objective of this project is shape optimization and structural stability the butterfly valve for metallic nonmetallic materials mostly used in engine carburetors need to make plays role component, design modifications material comparative analysis done ANSYS Structural modules find optimized through stress, strain deformation results
