this paper develops new results on the use of model predictive control to regulate the attitude of a ground station antenna. two degree of freedom az-el pedestal is considered as ground station antenna. permanent magnet synchronous motors are taken into consideration as the best choice for satisfaction of control objectives as actuators. the design is based on a two cascade controller consist o...

Permanent facial paralysis is a catastrophic event for involved patients. In long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. But its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. This article advocate a new modification for resolving this problem with concomitant el...

Background: It is unclear whether hemiarthroplasty (HA) or reverse shoulder arthroplasty (RS) are superior for patientswith cuff tear arthropathy (CTA) and preserved preoperative motion (elevation >90˚).Methods: This was a retrospective, single institution study. Patients who underwent RSA or HA for CTA were included ifthey had preserved preoperative motion with a minimum of 2...

abstract   background : cancer has not been elucidated in colerectal site. c-reactive protein (crp) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (il-1), interleukin-6 (il-6), and tumor necrosis factor (tnf). the significance of a preoperative serum elevation was evaluated using crp as a predictive indicator f...

background: this study was carried out to observe the radioprotective effects of rosemarinus officinalis leaves extract (roe) against radiation-induced histopathological alterations in liver of mice. materials and methods: adult swiss albino mice were exposed to 6 gy gamma radiation in the presence (experimental) or absence (control) of roe to study the qualitative and quantitative alterations ...

This study aimed to evaluate effects of elevation and phenological stage on essential oil components of Teucrium polium L. and Teucrium orientale L. belonging to the Lamiaceae family. The aerial parts of the grown plants in two ranges of elevation including 2000-2500 and 2500-3000 m above sea level were harvested at three time-points, including end of vegetative, flowering, and seed filling sta...
