agronomic effectiveness of partially acidulated asfordi phosphate rock on canola in two calcareous and non-calcareous soils
yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...

15 صفحه اولMolecular Surveying of the Common Variants of Glucose 6-Phosphate Dehydrogenase Gene in Deficient Patients
Glucose 6-phoshphate dehydrogenase is X-chromosome linked that expressed in all tissues. This is the first enzyme of pentose phosphate pathway were 5-carbon sugar Ribose and NADPH were synthesized by coupled oxidation /reduction reactions and this enzyme is a highly polymorphic enzyme in humans. G6PD deficiency are shown to be the cause of haemolytic effect of Fava beans and primaquine. It soon...

رشد انفجاری تکنولوژی فرصت های آموزشی مهیج و جدیدی را پیش روی فراگیران و آموزش دهندگان گذاشته است. امروزه معلمان برای اینکه در امر آموزش زبان بروز باشند باید روش هایی را اتخاذ نمایند که درآن ها از تکنولوژی جهت کمک در یادگیری زبان دوم و چندم استفاده شده باشد. با در نظر گرفتن تحولاتی که رشته ی آموزش زبان در حال رخ دادن است هم اکنون زمان مناسبی برای ارزشیابی نگرش های موجود نسبت به تکنولوژی های جدید...
15 صفحه اولThe Effect on the Citric Solubility of Langebaan Phosphorite (lanigebaan Phosphate Rock) When Composted with Filter Cake
Dymond's 1951 compost experiments with filter cake and Langebaan phosphate rock were continued in 1952. Composting increased the citric solubility of the phosphoric oxide in the rock, although not to .the same extent as in the 1951 experiments. Citric solubility decreased with increasing quantities of phosphate rock. Field trials on sugar cane in Natal have been initiated to determine the avail...
