neospora caninum is an intracellular parasite which causes abortion in cattle worldwide. The aim of this study was to determine the seroprevalence of neospora caninum in cattle in the province of Kerman in South East Iran. Blood samples were collected from 285 cattle in the province of Kerman for determining the seroprevalence of neospora caninum. A total of 285 serum samples were tested for an...

Arg(285), one of the very few conserved residues in the active site of d-amino acid oxidases, has been mutated to lysine, glutamine, aspartate, and alanine in the enzyme from the yeast Rhodotorula gracilis (RgDAAO). The mutated proteins are all catalytically competent. Mutations of Arg(285) result in an increase ( approximately 300-fold) of K(m) for the d-amino acid and in a large decrease ( ap...
A total of 285 adult patients (123 men and 162 women) with AD who married non-atopic persons and had at least one child have been seen in our outpatient clinic over the past 8 years (1990 ^ 97). All had moderate to severe disease. A personal history of respiratory atopy was obtained in 137 (48%) of the 285 patients. All patients ful¢lled the diagnostic criteria of Hani¢n & Rajka (1). In the 285...
Intestinal nematodes are among the most common parasites of dogs, being Toxocara spp. and Ancylostoma spp. threats to public health due to their zoonotic potential. In this study, three parasitological diagnostic techniques for detecting the eggs/oocysts of canine intestinal parasites were evaluated. Fecal samples (n = 285) were collected from the environment (i.e. public streets, squares and h...
PURPOSE To describe the United States Army Ocular Teleconsultation program and all consultations received from its inception in July 2004 through December 2009. DESIGN Retrospective, noncomparative, consecutive case series. METHODS All 301 consecutive ocular teleconsultations received were reviewed. The main outcome measures were differential diagnosis, evacuation recommendations, and origi...
هدف از این تحقیق پیشبینی میزان مصرف سوخت تراکتور ناشی از تغییرات عرض تیغۀ گاوآهن قلمی و تعیین رابطهای بین نسبت ظاهری( ) و میزان مصرف سوخت است. بدین منظور از یک تراکتور 399-ITM و یک گاوآهن قلمی 9شاخۀ سوار با عرض تیغههای 5 و 10 سانتیمتر استفاده شد. خاک لومیـرسی و محتوای رطوبت 9درصد براساس وزن خشک بود. سه سطح عمق شخمزنی ( 10، 15، و 20 سانتیمتر)، سه سطح سرعت پیشروی (3، 4، و 5 کیلومتر بر ...
کاربرد وسیع تراکتورها به عنوان نیروی محرکه در عملیات های مختلف کشاورزی از قبیل خاکورزی، کاشت و داشت، اتوماسیون این وسیله را مورد توجه محققین قرار داده است. بالا بردن آسایش راننده و راندمان کاری توسط هدایت بدون سرنشین تراکتور در همین راستا قرار می گیرد. در این پروژه اقدام به طراحی، ساخت و ارزیابی یک سامانه هدایت از راه دور تراکتور شده است. جهت مشاهده مسیر و چرخاندن میل فرمان، به ترتیب از یک عدد ...
