We try to understand recent data on proton-proton and deuteron-gold collisions at RHIC, employing a modified parton model approach. 1 Interesting data from RHIC The nuclear modification factor R = (dNAA/d pt) / (Ncoll dNpp/d pt) shows interesting features: For AuAu, it is much smaller than one for central collisions, whereas for d-Au, it is bigger than one for central collisions. With decreasin...

Expression of genes encoding type II restriction/modification (R/M) systems, which are widely spread in eubacteria, must be tightly regulated to ensure that host DNA is protected from restriction endonucleases at all times. Examples of coordinated expression of R/M genes that rely on the action of regulatory factors or the ability of methyl transferases to repress their own synthesis by interac...

In force-based seismic design, the behavior factor q (or response modification R) is devised to prevent overdesign by reducing design force. Different values of are available for various structure types. However, masonry fence walls not categorized in current codes. These poor quality due absence proper assurance and maintenance, most those structures inclined. this study, leaning experimentall...

امروزه، در بیشتر اراضی سرعت فرسایش خاک بیش از سرعت تشکیل خاک است. در نتیجه باعث تهی شدن منابع خاک و کاهش توانایی حاصلخیزی خاک می شود. در ایران استان گلستان به علت موقعیت جغرافیایی و اقلیمی آن و تخریب بالای منابع آن و همچنین به علت اینکه سطح وسیعی از اراضی از لس تشکیل شده دارای میزان فرسایش خاک بالایی می باشد. یکی از راه های تخمین میزان فرسایش و رسوب و بررسی میزان تلفات مواد غذایی خاک استفاده از...

با توجه به اهمیتی که رودخانه ها در تأمین منابع آب بشر دارند، آگاهی از میزان رواناب و بار رسوبی که حمل می کنند می تواند بشر را در برنامه ریزی های آینده در منابع آب یاری نماید. امروزه، کاربرد روش های سیستمی به خاطر توانایی پردازش حجم بالایی از داده ها در مدت زمان کوتاه در برنامه ریزی منابع آب در حال افزایش می باشد. از آنجایی که مدل swat2009 یک مدل جامع و کامل جهت ارزیابی فرآیندهای هیدرولوژیک در س...

BACKGROUND Cardiovascular events are less prevalent in premenopausal women and women receiving estrogen replacement than in postmenopausal women or men. Endothelium-derived relaxing factor (EDRF) is an important local modulator of vascular tone, and abnormal endothelial function is related, in part, to the oxidative modification of low-density lipoprotein (LDL). Estrogens possess substantial an...

Erythropoietin (EPO), an essential hormone for erythropoiesis, can provide protection against myocardial ischemia/reperfusion (I/R) injury and hypoxic apoptosis. GATA-4 is a zinc finger transcription factor, and its activation and post-translational modification are essential components in the transcriptional response to hypoxia. GATA-4 has also been reported to play a role in the cellular mech...
