The Global Cancer Genomics Consortium (GCGC) colleagues continue to function together as an interactive multidisciplinary team of cancer biologists and oncologists with interests in genomics and building a bidirectional bridge between cancer clinics and laboratories while taking advantage of shared resources among its member scientists. The GCGC includes member scientists from six institutions ...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
1. Introduction Among sedimentary systems that are rich and poor in terms of sediment load, a different organization of the sand dunes can be seen. Barchan dunes are one of the accumulative landforms of wind that are considered from poor sedimentary systems in desert environments. The dunes are the crescent shape, and have two horns at the end. Along the horns the prevailing wind direction...
چکیده : دو گیاه perovskia abrotanoides karel و zeravschania aucheri در سایه تحت جریان ملایم هوا خشک شدند. اسانس گیری از گیاهان خشک شده توسط دو روش تقطیر با آب و میکرواستخراج فاز جامد در فضای فوقانی انجام گرفت و اسانس ها با استفاده ار روش کروماتوگرافی گازی- طیف سنج جرمی (gc-ms) مورد تجزیه و تحلیل قرار گرفتند. ترکیبات عمده شناسایی شده در اسانس برگ و گل و ساقه گیاه p.abrotanoides عبارتند از: ...
background: asymptomatic malaria infection provides a reservoir of parasites, causing the persistence of malaria transmission. it accounts an important challenge for successful management of the control, elimination, and eradication programmes in any malaria-endemic region. this investigation was designed to assess the presence and the prevalence of asymptomatic carriers in iranshahr district o...
The studied area, as Ykeh-Chah unit, is a part of Golpayegan magmatic and metamorphic complex in Sanandaj-Sirjan structural zone. The unit consists of mylonitized and high- grade metamorphic rocks, including biotite-gneiss, biotite-garnet-gneiss, amphibolite and orthogneiss. The biotite gneiss and the biotite garnet gneiss have partly been migmatitized. They show various structures such as stro...
Torud-Chah Shirine magmatic arc is located in south of Semnan. This arc is composed of Cenozoic volcanic, pyroclastic and intrusive rocks. The Kuh-Zar in manning province of Bagho is outstanding with Cu-Au mineralization. Mining is restricted to hydrothermal alteration zones in the area. Alteration zones includes propylitic, phyllic, advanced argillic and silicic. The rare association of tourma...
On the basis of comprehensive RFLP analysis, it has been inferred that approximately 97% of Native American mtDNAs belong to one of four major founding mtDNA lineages, designated haplogroups "A"-"D." It has been proposed that a fifth mtDNA haplogroup (haplogroup X) represents a minor founding lineage in Native Americans. Unlike haplogroups A-D, haplogroup X is also found at low frequencies in m...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
یکی از مهم ترین عوامل موثر در وقوع آتش سوزی در مناطق خشک، پوشش گیاهی و شرایط آب و هوایی منطقه می باشد. منطقه حفاظت شده باغ شادی یکی از مناطق جنگلی استان یزد بوده که بیش ترین آتش سوزی های استان در آن رخ داده است. به منظور بررسی عوامل موثر بر وقوع آتش سوزی در این منطقه از روش تحلیل سلسله مراتبی (ahp) استفاده شد و معیارهای فیزیوگرافی شامل سه زیرمعیار ارتفاع، شیب و جهت شیب، اقلیم شامل دو زیرمعیار د...
