Abstract. Integrating the hybrid and multiscale analyses parallel computation is necessary for current data assimilation schemes. A local method, Local DA, designed to fulfill these needs. This algorithm follows grid-independent framework of ensemble transform Kalman filter (LETKF) more flexible in analysis than LETKF. DA employs an explicitly computed background error correlation matrix model ...
فرض کنیمr یک حلقه تعویض پذیر ویکدار موضعی باشدو(j(r رایکال جیکوبسن r و(z(r مجموعه مقسوم علیه های صفر حلقه r باشد.گوییم r یک حلقه z- موضعی است هرگاه j(r)^2=. .همچنین برای یک حلقه تعویض پذیر r فرض کنیم c یک عنصر ناصفر از (z( r باشد با این خاصیت که cz( r)=0 گوییم حلقه موضعی r یک حلقه c - موضعی است هرگاه و{0 و z(r)^2={cو z(r)^3=0, نیز xz( r)=0 نتیجه دهد که x عضو {c,0 } است. در این پایان نامه ساخ...

Introduction: The physiological process of sternum surgical fracture consolidation in patients undergoing cardiac surgery could be prolonged by the invasion of gram-positive saprophytic bacteria which perpetuates the local inflammatory process despite the standardized aseptic and antiseptic measures in cardiac surgery. In this regard, the topical application of Vancomycin can e...
Skin permeability and local blood perfusion are important factors for transdermal drug delivery. Application of heat is expected to enhance microcirculation and local perfusion and/or blood vessel permeability, thus facilitating drug transfer to the systemic circulation. In addition, heating prior to or during topical application of a drug may facilitate skin penetration, increase kinetic energ...
