Experiment of Fractioning Animal Cell Culturing Solution in High Concentration under Microgravity

degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...

The Lambda Point Experiment in Microgravity

in C)ctober 1992 a low temperature experiment was flown on the Space Shuttle in low earth orbit, using the J]’I. low temperature research facility. The objective of the mission was to measure the heat capacity and thermal relaxation of helium very close to the lambda point with the smearing effect of gravity removed. We describe the experiment with emphasis on the high resolution thermometry an...

The Lambda Point Experiment in Microgravity

The remarkable phenomena which occur when a system undergoes a cooperative phase transition have claimed the attention of scientists for many years. It was recognised that the unusual behavior was a result of the interactions between the constituents of the system, but a realistic treatment of the problem, either microscopic or phenomenological, appeared prohibitively difficult. In the early 70...

[Spatial orientation under microgravity].

On Earth, humans are constantly exposed to the gravity. During head and body tilts, the otolith organs sense changes in head orientation with respect to the gravitational vertical. These graviceptors also transduce transient linear acceleration generated by translational head motion and centripetal acceleration during rotation about a distant axis. When individuals are rotated at a constant vel...
