The present study reports the age, growth, and reproduction parameters of 52 brown rays (Raja miraletus) captured from Saros Bay (Northern Aegean Sea) between September 2006 -2008. males females accounted for 44.2% 55.8% sample, respectively. measured 10.5-53.5 cm (disc width, 6.5-32 cm) ranged 25.5-47.7 18-30.5 in total length (TL). equations TW=0.0017*TL3.27 TW=0.0017*DW3.38 were used to desc...

A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...

Mechanical hill direct seeding of hybrid rice could be the way to solve the problems of high seeding rates and uneven plant establishment now faced in direct seeded rice; however, it is not clear what the optimum hill seeding density should be for high-yielding hybrid rice in the single-season rice production system. Experiments were conducted in 2010 and 2011 to determine the effects of hill s...

What was once a simple lumbar disc herniation treated with laminotomy and partial discectomy, with typically excellent results (25, 46), has evolved into a surprisingly complex clinical problem with a dazzling array of therapeutic alternatives. Much of this, of course, is based on clinical studies emphasizing the heterogeneity of disc disorders. Advances in biomechanics research focusing on the...

Six strains of chloramphenicol (CM)-resistant endospore-forming bacteria, which can grow in the presence of 100 microgram/ml of CM, were isolated and identified as Bacillus badius. Mechanism of CM-resistance in one of the isolated strains, Bacillus badius 211, was investigated. No inactivation of CM was demonstrated when the strain was grown in nutrient broth containing 100 microgram/ml of CM, ...

We investigate the anatomy of the lumbosacral anterior great vessels using computer tomography (CT) angiography before L5/S1 anterior interbody surgery. Sixty-two adult patients were selected. The location of the abdominal aortic bifurcation and common iliac venous confluence in the lumbar vertebrae and the anatomic parameters of the iliac vascular space (e.g., distances from the included angle...
