Livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. This research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of Artemisia aucheri. Hence, two rangelands of enclosure (Shahtappeh-Chah Mahmood) and no enclosure (Chiro) were chosen in Sem...

{Recent advances in global optimization for process synthesis, design and control are discussed. After a review of the chemical engineering contributions, we focus on the enclosure of all solutions of nonlinear constrained systems of equations. Important theoretical results are presented accompanied with computational studies on the enclosure of multiple steady states and all homogeneous azeotr...

It is shown that thermomechanical treatment (TMT) of the EK61 superalloy with a strain rate (ε∙) 10−3 s−1 and gradual decrease in temperature from (0.92 – 0.65)Tδ leads to transformation initial coarse-grained structure into an ultrafine-grained (UFG) mixed type structure. Such UFG microstructure consists γ-phase grains δ-phase particles 0.3 μm size relatively large up 2 size. The having such e...

The proposed antenna presents a microstrip filter with both out-of-band rejection characteristics and radiation for WLAN communication system. consists of four U-shaped resonators, one Γ-shaped antenna, parallel coupling line. has the filtering function as last order resonator, line integrates conductance converter. After simulation test, results show that center frequency is 5.25 GHz, fraction...

The Supernova Remnant MSH 15-52 has been observed in very high energy (VHE) γ-rays using the H.E.S.S. 4-telescope array located in Namibia. A γ-ray signal is detected at the 25 sigma level during an exposure of 22.1 hours live time. The image reveals an elliptically shaped emission region around the pulsar PSRB1509–58, with semi-major axis ∼6′ in the NW-SE direction and semi-minor axis ∼2′. Thi...

The present paper aims to analyze the thermal convective heat transport and generated irreversibility of water-Cu-Al2O3 hybrid nanosuspension in an odd-shaped cavity. side walls are adiabatic, internal external borders enclosure isothermally kept at high low temperatures Thand Tc, respectively. control equations based on conservation laws formulated dimensionless form worked out employing Galer...

New forms of vanadium oxide Nanoporous were fabricated using a simple chemical synthesis method. Vanadium pentoxide (V2O5) Nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD), Four...
