Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...

To assess and compare anteroposterior jaw dysplasia indicators i.e. (Wits-appraisal, ANB-angle, β(Beta)-angle, W-angle, YEN-angle π(Pi)-angle) in Angle's Class I molar relation subjects with normal overjet of central India. Sum 40 lateral cephalograms were traced line the inclusion criteria Angle’s subjects. Subjects had to be between ages 18 30 have a aligned arches. We measured compared Wits-...

satellite thermal control ensures safe operating temperature ranges for satellite components throughout the mission life. effects of altitude, spin, and position of satellite radiator(s) on the thermal control of a small low earth orbit (leo) satellite have been studied. results show that change in satellite altitude, in the range considered here, does not produce critical thermal conditions. h...

PURPOSE To determine the optic disc-fovea angle (defined as angle between the horizontal and the line between the optic disc center and the fovea) and to assess its relationships with ocular and systemic parameters. METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals. A detailed ophthalmic examination was carried out. Using fundus photographs, we meas...

Introduction: In orthodontic diagnosis and treatment planning an accurate evaluation of sagittal jaw relationship is important. To assess the antero-posterior jaw discrepancy between maxilla and mandible, numerous angular and linear measurements have been in corporate so as to reach correct diagnosis. So the purpose of this study is to compare ANB angle, Wits appraisal, Beta angle and W angle u...

For orthodontic diagnosis and treatment planning there are various ways to assess the jaw discrepencies. Using parameters such as ANB, Wit’s appraisal, Beta, Yen, W angles, with some limitations. To overcome these, MKG angle Tau were proposed.
 Aim objective: The present study assesses predictability of its correlation previous parameter. Materials methods: A total 105 lateral cephalograms...

The impacts of linear environmental shears on beta drift direction are assessed through numerical experiments with a single-layer, primitive equation model. It is found that cyclonic (anticyclonic) shears turn the beta drift more westward (northward) in the Northern Hemisphere. In addition, the longitudinal shear of meridional flows (]V/]x) is much more effective than the meridional shear of zo...

AIM To compare the pattern of localised nerve fibre layer (NFL) defects in normal tension glaucoma (NTG) and primary open angle glaucoma (POAG). METHODS 50 NTG eyes and 36 POAG eyes, all with localised NFL defects, were enrolled. On retinal NFL photography, the proximity of the defect to the centre of the fovea (angle alpha) and the sum of the angular width of the defects (angle beta) were de...
