Objective- This study was performed to evaluate and compare grossly and pathologically two surgical techniques of amniotic membrane patching on experimental corneal alkali burn in dogs. Design- Experimental study. Animals- Fifteen healthy dogs Procedures- The central corneas of the dogs were inflicted by applying a round filter paper, 6.0 mm in diameter, soaked in 1 N NaOH for 60 sec. ...
New antimicrobial hydrogels were prepared via reaction of functionalized-Tragacanth Gum biopolymer by glycidyltrimethylammonium chloride (QTG) with acrylamide (AM). Characterization of the QTG hydrogels with AM (QTG-AM) was carried out by thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and 1HNMR. Swelling behaviour of the QTG hydrogels was investigated on the p...
Chickpea (Cicer arientinum L.) is one of the Leguminosae family members that has symbiotic ability with Mesorhizobium ciceri bacteria and arbuscular mycorrhizal (AM) fungi. To evaluate the effect of AM fungi (Glomus mosseae, Glomus intraradices) and Mesorhizobium ciceri bacteria at three soil moisture levels [28% (field capacity), 15% (-5 bar suction) and 9% (-10 bar suction)] on nutrients conc...
The acidity constants of some amino acids (Am) were determined by potentiometric pH titration. The stability constants of the 1:1 complexes formed between M2+: Ca2+, Mg2+, Mn2+, Co2+, Ni2+, Cu2+ or Zn2+ and Am2-, were determined by potentiometric pH titration in aqueous solution (I = 0.1 M, NaNO3, 25°C). The order of the stability constants was reported. It is shown that the stability of the bi...
در این پایان نامه، پاسخ شمارنده تناسبی با پوشش داخلی بور (boron-lined proportional counter) به چشمه نوترون-گامای am-be با یک برنامه فرترن به روش مونت کارلو شبیه سازی شده است. برای این آشکارساز که کاربردهای ویژه ای در شمارش نوترون خصوصاً در چاه پیمایی هسته ای دارد، شاخص های مهم بهینه سازی بهره آشکارسازی، شامل ابعاد آشکارساز، هندسه تابش دهی و ضخامت لایه ی بور بررسی شده و همچنین، شبیه سازی مونت کار...
