In this paper a Frequency Selective Surface (FSS) as a UWB electromagnetic shield is introduced. The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C ...

the aim of this study was to investigate the effect of 8 weeks of selective exercise activity and estrogen supplement on satellite cells in ovariectomized sprague-dawley rats. at first, subjects were ovariectomized and after one month of complete recovery, they were randomly divided into four groups: control, exercise activity, estrogen supplement, and exercise and estrogen supplement. only exe...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the competitive inhibitors of cyclooxygenase (COX), the enzyme which mediates the bioconversion of arachidonic acid to inflammatory prostaglandins (PGs). Their use is associated with the side effects such as gastrointestinal and renal toxicity. The therapeutic anti-inflammatory action of NSAIDs is produced by the inhibition of COX-2, while the ...

Carboxylate reductases (CARs) are valuable catalysts for the selective one-step reduction of carboxylic acids to their corresponding aldehydes. In recent years, numerous new CARs have been made available, studied and applied in context biocatalytic syntheses. The preparation aldehydes as end products flavor fragrance sector integration cascade reactions with key intermediates represent two majo...

there are many real problems in which multiple responses should be optimized simultaneously by setting of process variables. one of the common approaches for optimization of multi-response problems is desirability function. in most real cases, there is a correlation structure between responses so ignoring the correlation may lead to mistake results. hence, in this paper a robust approach based ...

Cu–Ga catalysts are potential candidates for activating the selective and stable hydrogenation of carbon dioxide to methanol dimethyl ether. This work explores structure–function relationship in specific Cu–Ga/CeO 2 –ZrO with different Ga loadings. Combining experiments density functional theory calculations, we find most well-balanced interphase (structure) promote mechanistic pathways reactio...
