conclusions decreasing barriers to physical activity among the elderly causes physical activities to increase; therefore, energy expenditure is increased. decreasing social and environmental problems for the elderly is effective in increasing physical activity and energy expenditure. results the average age among the study population was 67.6 ± 6.8 years median, and the interquartile range (iqr...

The tunneling dynamics in relativistic strong-field ionization is investigated with the aim to develop an intuitive picture for the relativistic tunneling regime. We demonstrate that the tunneling picture applies also in the relativistic regime by introducing position dependent energy levels. The quantum dynamics in the classically forbidden region features two time scales, the typical time tha...

Gentiana lutea is a herbal bitter drug that is used to enhance gastrointestinal motility and secretion. Recently we have shown that amarogentin, a characteristic bitter compound of Gentiana lutea extract (GE), binds to the bitter taste receptors TAS2R1 and TAS2R38 in human keratinocytes, and stimulates the synthesis of epidermal barrier proteins. Here, we wondered if GE also modulates lipid syn...

High Purity Germanium detectors (HPGe) are subdivisions of semiconductor detectors which are widely used in nuclear technology from space industry to nuclear medicine, due to their high resolution, low dead time, unlimited size and compatibility with a variety of environments. The( absolute and intrinsic) efficiency of the HPGe detector, which depends on the geometry of the source-detector syst...

شهین مرادنسب بدرآبادی 1، داریوش سرداری2، میترا اطهری2آشکارسازهای ذرات یا پرتو ابزاری هستند که با آن ها ذرات پرانرژی را آشکار، ردیابی یا شناسایی می کنند. یکی از این آشکارسازها گالیم آرسناید (gaas) می باشد. مشکلات در تولید لایه های ضخیم با دوپینگ (ناخالص سازی یا تغلیظ) به اندازه کافی کم نیاز به عمق های تهی سازی کافی (بیشتر از 100 میکرومتر) داشت، در حالی که مانع توسعه بیشتر می شدند. سپس، علاقه جدی...

most common hypotheses of seizure initiation are increased neural excitation, decreased inhibition or both. but, the conditions that lead to these activation states not to be clear yet. recent studies challenge traditional concepts and indicate new evidence that a key epileptogenic process may actually begin in the blood vessel. seizures could be initiate by a variety of insults to the brain, s...
