A-type granites are typically formed in stable intra-plate, back-arc or postcollisional settings and characterized by highly ferroan potassic major element compositions, strong enrichment incompatible trace elements. Unlike I-, S- M-type granites, where the letters denote dominant source material (igneous, sedimentary mantle derived), there is no consensus on processes giving rise to magmas. In...
بررسیهای ژئوشیمی و رادیوایزوتوپی برای تعیین خاستگاه آپاتیت در ذخایر آهن و آپاتیت منطقهی معدنی بافق
The iron-apatite deposits of the Bafq mining district contain elevated REE content and occur together with vast alterations in country-rock which were formed due to widespread hydrothermal processes in Early Cambrian. Apatite and rare earth element geochemistry as well as radioactive isotope studies of Sm-Nd show that apatite formation might be due to hydrothermal activities and remobilization ...
Loco-granite and granodiorite intrusive bodies have cut the Naiband and Sangestan Formations in Darreh-Zerreshk area in southwest margins of Shirkooh batholite. This intrusion has caused weak metamorphism and copper hydrothermal mineralization in permeable Sangestan Formation. The characteristics minerals are magnetite, chalcopyrite, pyrite, bournite and dyajenite. The studied area is composed ...
purpose the aim of this study was to determine the effect of ramadan fasting on body composition, calorie intake and physical performance in young female athletes undertaking training sessions during ramadan. methods twelve voluntary female athletes (15-27 years old) were assigned to the research. a prospective study was conducted to investigate the athletes on four different occasions: one wee...
samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...
evaluation of four safflower (carthamus tinctorius l.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from isfahan14 genotype (34.39%, respectively). among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...
we give some sufficient conditions under which the tuple of the adjoint of weighted composition operators $(c_{omega_1,varphi_1}^* , c_{omega_2,varphi_2}^*)$ on the hilbert space $mathcal{h}$ of analytic functions is supercyclic.
the essential nutrients in the pharmacological plants play a significant role in the remedy of illnesses but, these elements at high levels; can also be dangerous and toxic. the aim of this study was to determine the concentration of macro (mg, ca, p, and k) and micro (cu, zn, fe and mn) essential elements in seven indigenous pharmacological plants growing in fars province, southern iran. they ...
effect of dietary free l-lysine on growth, food intake, and muscle composition of beluga juveniles were investigated over 6 weeks. control diet lysine content was 2.1% of dry matter (4.4% of dietary protein). three experimental diets were prepared by adding lysine (0.5, 1 and 1.5%) to control diet to obtain diets containing 2.6, 3.1 and 3.6% of dry matter lysine (corresponding to 5.5, 6.6 and 7...
fenugreek (trigonella foenum graecum), native to southern europe and asia, is an annual herb with white flowers and hard, yellowish brown and angular seeds, known from ancient times, for nutritional value beside of its medicinal effects. fenugreek seeds are rich source of gum, fiber, alkaloids, flavonoids, saponins and volatile content. due to its high content of fiber, fenugreek could be used...
