The nature of the surface of Venus is one of the keys to answering fundamental questions about the origin and evolution of the terrestrial planets and is of critical significance to comparative planetology. The last 25 years of solar system exploration have provided unprecedented views of the Earth, Moon, Mars, and Mercury. These views have shown that the smaller terrestrial planetary bodies (t...

background scapula fractures occur in approximately 1% of all fractures and constitute about 3% - 5% of all injuries of the shoulder joint. objectives this study aimed to evaluate the clinical outcomes of 20 surgically treated patients with displaced glenoid fractures after stabilization with distal radius plate. methods between 2012 and 2015, at 2 centers (hmch & shce) of bhubaneswar odisha, w...

In our solar system, the densely cloud-covered atmosphere of Venus stands out as an example how polarimetry can be used to gain information on cloud composition and particle mean radius. With current interest running high discovering characterizing extrasolar planets in habitable zone where water exists liquid state, making use spectropolarimetric measurements directly-imaged exoplanets could p...

Background: Expansion of bone marrow cavity and decreased cortical and trabecular bone tissues and osteoporosis are resulted from beta-thalassemia. The aim of this study was to assess bone mineral density (BMD) in patients with β thalassemia major and intermedia, and to determine their biochemical and hormonal profiles that may affect BMD. Materials and Methods: In a cross sectional study from ...

Recently, we initiated in [Systems Control Lett., 26 (1995), pp. 245–251] the study of exponential stability of neutral stochastic functional differential equations, and in this paper, we shall further our study in this area. We should emphasize that the main technique employed in this paper is the well-known Razumikhin argument and is completely different from those used in our previous paper ...

 Background: Mal:::union::: is the most common complication following distal radius fractures. Aim of this study was to evaluate the results of distal radius corrective osteotomy and plate fixation by dorsal approach in the mal:::union:::. Methods: In this retrospective study, 14 patients with neglected distal radius mal:::union::: from 2005 to 2011 were studied. All patients were treated ...

field ion microscopy (fim) and scanning tunneling microscopy (stm) have found a wide application in nanotechnology. these microscopes use a metallic nanotip for image acquisition. resolution of fim and stm images depends largely on the radius of nanotip apex; the smaller the radius the higher the resolution. in this research, for tungsten nanotip fabrication, electrochemical etching of tungsten...

materials and methods: one hundred and thirty five mesial root canals of mandibular first and second molar teeth were selected. access cavities were prepared. after inserting a k-file size #10 into each canal, radiographs were taken. canal curvature was determined by measuring the schneider angle, canal access angle, as well as the canal radius, length, height and curvature starting distance on...
