Increased Greenland ice sheet melting has an impact on global mean and regional sea level rise the ocean circulation. In this study, we explore whether signatures found in model simulations are visible observations from radar altimetry, satellite gravimetry Argo floats. We have included freshwater flux (GF) Finite-Element-Sea ice-Ocean Model (FESOM) for years 1993–2016. The reference run is com...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
We study the signature of rainfall on S1cm, the sea surface salinity retrieved from the Soil Moisture and Ocean Salinity (SMOS) satellite mission first by comparing SMOS S1cm with ARGO sea surface salinity measured at about 5 m depth in the Intertropical Convergence Zone (ITCZ) and in the Southern Pacific Convergence Zone; second by investigating spatial variability of SMOS S1cm related to rain...
The long-term sea level change during 1993 – 2008 is investigated in the Malaysian Seas from satellite altimetry data of the Topex, Jason-1, ERS-1, ERS-2 and Envisat missions. During the past two decades, satellite altimeter has provided its capability in measuring the global mean of sea level with precision better than 1 mm/year. Sea level data retrieval and reduction were carried out using Ra...
Global Navigation Satellite System Reflectometry (GNSS-R) has emerged as a promising remote sensing technique for coastal sea level monitoring. The GNSS-R based on signal-to-noise ratio (SNR) observations employs single antenna and conventional receiver. It performs best low elevation satellites, where direct reflected radio waves are very similar in polarization direction of arrival. One the d...
abstract this mixed method study examines whether there is any relationship among the variables of the study (job satisfaction, social capital and motivation). the researcher considered job satisfaction and social capital as independent variables; motivation is the dependent variable of the study. the researcher applied a questionnaire to assess each variable. to measure efl teachers’ job sati...
چکیده هدف اصلی این پژوهش شناسایی الزامات نظام مدیریت کیفیت فراگیر در حوزه پژوهشی دانشگاه اصفهان بود. سوالهای پژوهش با توجه به مولفه های مدیریت کیفیت (تعهد مدیران، بهبود مستمر فرایندها ، مشتری محوری ، منابع انسانی ، مدیریت اطلاعات ، زیرساختهای کیفیت ، استفاده از نتایج ، انعطاف پذیری، مشارکت در فعالیتهای پژوهشی، ایجاد فرهنگ کیفیت و تناسب ساختارهای سازمانی) که بر اساس مطالعه استانداردهای بین المل...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
