in order to reduce consumption of chemical fertilizers and in order to evaluate the effect of biofertilizers on yield and yield components of sunflower nuts (helianthus annuus l.), the research was carried out with using factorial based randomized complete block design with three replications at agriculture and natural resources researches station of khoy in 2011. the first factor was  three su...

Normal values of the antero-posterior diameter of the head of the pancreas are of utmost value in radiological practice. With more than 60% of diseases and tumours of the pancreas occurring in its head, knowledge of its normal size is essential to the clinician. Computed tomography (CT) is the most effective technique for the diagnosis and staging of pancreatic carcinoma and magnetic resonance ...

BACKGROUND In equine athletes, dynamic stenotic disorders of the upper airways are often the cause for abnormal respiratory noises and/or poor performance. There are hypotheses, that head and neck flexion may influence the morphology and function of the upper airway and thus could even induce or deteriorate disorders of the upper respiratory tract. Especially the pharynx, without osseous or car...

BACKGROUND Various head and neck positions in sport horses are significant as they can interfere with upper airway flow mechanics during exercise. Until now, research has focused on subjectively described head and neck positions. The objective of this study was to develop an objective, reproducible method for quantifying head and neck positions accurately. RESULTS Determining the angle betwee...

In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...

This study explored the radiographic and anatomical differences in normal shoulders between men and women, as well as factors such as race, height, weight, and age. A total of 205 patients with documented normal anatomical radiographs comprised the study population. Five fellowship-trained orthopedic surgeon reviewers measured head diameter, humeral head size, head to tuberosity distance, great...
