Validation studies of current GPS radio occultation experiments using meteorological analyses consistently report on a negative refractivity bias in the lower troposphere. It is shown that refractivity profiles obtained from Doppler-inverted bending angle profiles not only deviate significantly within zones of multipath propagation but also depend on the selected end point of the occultation si...

هدف: از چالش­های عمده بشریت افزایش افسردگی و اختلال عملکرد جنسی ناشی داروهای ضدافسردگی است. با توجه به نقش سلول­های سرتولی در اسپرماتوژنز، پژوهش حاضر، اثر داروی دولوکستین را بر زنده­مانی، آپوپتوزیس بیان ژن­های Bax و­ (Connexin 43) Cx43 بررسی کرده مواد روش‌‌ها: TM4 محیط DMEM/F12 حاوی %5/2 FBS، 5% سرم اسب %1 پنی سیلین-استرپتومایسین کشت شدند. دوزهای 30،60، 15، 5/7، 75/3 میکرو­گرم/ میلی­لیتر زمان­ه...

In this paper we analyze quantitatively the concept of LAGEOS–type satellites in critical supplementary orbit configuration (CSOC) which has proven capable of yielding various observables for many tests of General Relativity in the terrestrial gravitational field, with particular emphasis on the measurement of the Lense–Thirring effect. By using an entirely new pair of LAGEOS–type satellites in...

Some 900 students paused Monday to pay tribute to “Sun­ shine,” who died that morning. ‘Sunshine” was a two-month old turtle. A funeral'procession of 15 cars, led by an 8-foot casket containing Sunshine’s body, wound its way through campus and stopped to hold a rally for the deceased. At the rally, 2S0 heard of Sun­ shine’s record of accomplish-, ments. The procession then moved on. ' Burial to...

cal evidence of which we are aware is that this technology is by far more complex than simply installing an automated-sorting scale unit and a set of one-way gates in a hog house. This complexity is evidenced by what appears to be incomplete animal adaptation, various design flaws, and unintended and un expected consequences of these systems. These problems – among others – have been confirmed ...
