Conservative behavior of terrestrial trace elements associated with humic substances in the coastal ocean

Coastal ocean and shelf-sea biogeochemical cycling of trace elements and isotopes: lessons learned from GEOTRACES

Continental shelves and shelf seas play a central role in the global carbon cycle. However, their importance with respect to trace element and isotope (TEI) inputs to ocean basins is less well understood. Here, we present major findings on shelf TEI biogeochemistry from the GEOTRACES programme as well as a proof of concept for a new method to estimate shelf TEI fluxes. The case studies focus on...

Conservative behavior of arsenic and other oxyanion-forming trace elements in an oxic groundwater flow system

the trace of translators ideology in literary translations: a case study of persian translation of the scaret letter

رساله ی حاضر تلاشی است برای بررسی مبحث ایدئولوژی در ترجمه ادبی و تاثیرات آن بر کار مترجم، اعم از گزینش واژگان و ساختارهای دستوری؛ با تمرکز بر تحلیل انتقادی گفتمان در متن مبدأ و متن مقصد، که در این رساله متن مبدأ رمان داغ ننگ اثر ناتانیل هاوثورن و ترجمه فارسی سیمین دانشور به عنوان متن مقصد مورد بررسی قرار گرفته است. تجزیه و تحلیل رمان های مورد نظر به طور عمده بر اساس مدل پیشنهادی فرحزاد(2007) بر...

Trace Elements Status in Sera of Patients with Allergic Asthma

Background: Asthma is a multifactorial disease and its severity varies with the inflammatory grade. There are conflicting reports about the roles of trace elements in asthma. This study examined the effects of zinc (Zn), copper (Cu), and selenium (Se) concentrations in sera of patients with allergic asthma attending Ghaem Hospital, Mashhad, Iran. Methods: Forty-nine patients, aged 10 to 50 y...
