The peak SAR values of two-element array antennas for mobile handsets in the vicinity of a spherical phantom of a human head are evaluated numerically as a function of the distance between the array antenna and the head phantom when the two elements of a two-element array antenna are either co-phase voltage-fed or reverse-phase voltage-fed. It is found that relation between the worst case of th...

Chronic, low level treatment with a carbon monoxide releasing molecule (CO-RM), CORM-A1, has been shown to prevent the development of obesity in response to a high fat diet. The objective of this study was to test the hypothesis that chronic, low level treatment with this CO-RM can reverse established obesity via a mechanism independent of food intake. Dietary induced obese mice were treated wi...

with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

Reverse water–gas shift reaction using renewable H2 is a promising route for CO2 upgrade, however, it restricted by the equilibrium. The chemical looping reverse oxygen carriers (i.e. Fe) has proven more effective utilization process to produce CO. However, with high purity needed obtain concentrated Herein, we propose calcium dual one-pot sol–gel synthesized Ca-Fe functional materials (DFMs). ...

An open reading frame encoding a putative polypeptide very similar to several lysyl-tRNA synthetases was found 10 nucleotides downstream of Rhizobium meliloti gltX encoding glutamyl-tRNA synthetase. Expression of this gene complemented a mutation in lysS of Escherichia coli and led to the overexpression of a polypeptide of the expected mass (62 kDa), thus confirming that it encodes R. meliloti ...

Pluronic L61 unimers, which are biomacromolecular modulators, and curcumin, a small-molecule modulator, were co-formulated into pH-sensitive micelles to reveal the full synergistic potential of combination drug treatments to reverse multidrug resistance (MDR). Compared to monotherapy, combined therapy significantly improved the cytotoxicity, cellular uptake and apoptotic effects of doxorubicin ...

The complete understanding of a molecular mechanism of action requires the thermodynamic and kinetic characterization of different states and intermediates. Cytochrome c oxidase reduces O(2) to H(2)O, a reaction coupled to proton translocation across the membrane. Therefore, it is necessary to undertake a thorough characterization of the reduced form of the enzyme and the determination of the e...

background and purpose: gastric cancer (gc) is one of the most common cancers worldwide and in iran. as conventional therapies such as surgery and chemotherapy are invasive with adverse effects, current studies are important as they are conducted to find natural compounds with few adverse effects. in this study, melittin with 26 amino acids was isolated and purified from bee venom and its effec...

Abstract Partial oxidation of methane (POM) by chemical looping with CO 2 co-feeding on La 0.8 Sr 0.2 FeO 3 (LSF) perovskite catalyst yielded a highly selective operation and enabled to extend the duration reduction cycle. In this work, conversion syngas was studied Fe (x) Co (1-x) O (x = 0, 0.25, 0.5, 0.75) perovskites in chemical-looping mode, methane. The reaction conducted at 850 °C, 15 min...
