The freezing and thawing process is a unique feature of the alpine permafrost ecosystem, which controls growth microorganisms meadows, plays vital role in animal husbandry development, ecosystem functions services. Meanwhile, also affected by external environmental factors, its spatial differences are very significant, especially regions over 5000 m a.s.l. In this study, periods Cuoma Township ...

Oxytocin (OXT) is a peptide hormone that binds the OXT receptor on myometrial cells, initiating an intracellular signaling cascade, resulting in accumulation of intracellular calcium and smooth muscle contraction. In other systems, an elevation of intracellular Ca(2+) stimulates nuclear translocation of the transcription factor, nuclear factor of activated T cells (NFAT), which is transcription...

B ackground. Each spring during the climatological peak of the severe weather season in the United States, the Experimental Forecast Program (EFP) of the National Oceanic and Atmospheric Administration’s (NOAA) Hazardous Weather Testbed (HWT) conducts a multiagency collaborative forecasting experiment known as the HWT EFP Spring Experiment. Organized by the Storm Prediction Center (SPC) and Nat...

در سالهای اخیر ورق‌های آلیاژ آلومینیوم در صنعت خودروسازی کاربرد وی‍ژه‌ای پیدا کرده‌اند. شکل‌دهی این مواد با روش‌های استاتیکی مانند هیدروفرمینگ و پرس بسیار مشکل است چرا که این ورق‌ها محدوده پلاستیک پیش از پارگی کمتری نسبت به ورق‌های فولادی معمول دارند. در این پژوهش شکل‌دهی آزاد آلیاژ آلومینیوم به عنوان مطالعه پایه‌ای بررسی شده است که با استفاده از موج شوک حاصل از انفجار در زیر آب و ماده منفجره S...

The recent financial crisis has raised several questions with respect to the financial institutions and banking industry. Hence, over the last decade the Iranian banking industry has undergone many substantial changes, such as liberalization, government regulation and technological advances.

BACKGROUND Most researches were focused on chemical constituents and bioactivities of Pedicularis. However, there were a few reports on simultaneous determination of the series phenylpropanoids compounds in Pedicularis by High Performance Liquid Chromatography (HPLC). OBJECTIVE To establish an HPLC method for simultaneous determination of salidroside, verbascoside, iso-verbascoside, leucosept...
