On disc protoplanet interactions in a non-barotropic disc with thermal diffusion
Aims. We study the disc planet interactions of low-mass protoplanets embedded in a circumstellar disc. We extend the standard theory of planet migration from the usual locally isothermal assumption to include non-barotropic effects, focusing on the validity of linear theory. Methods. We compared solutions of the linear equations with results from non-linear hydrodynamic simulations, where in bo...
متن کاملSteady Thermal Stresses in a Thin Rotating Disc of Finitesimal Deformation with Mechanical Load
Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here. The results obtained here are applicable to compressible materials. If the additional condition of incompressibility is imposed, then the expression for stresses corresponds to those arising ...
متن کاملConcomitance of Obesity and Overweight with Disc Height and Disc Herniation in Lumbar Spine
Background & Aim: Low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. Several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. The aim of this study wa...
متن کاملFluorescein diffusion in the human optic disc.
The characteristics of the transcapillary transfer of fluorescein dye in the optic disc of healthy individuals has been studied. A diffusible fluorescein dye and a nondiffusible reference substance, indocyanine green (ICG), which was assumed to remain in the capillaries, were injected into the circulatory system. The time courses of the concentrations of the two dyes in the optic disc were dete...
متن کاملDisc antibiogram test with graded plate method
Abstract Background and objectives: Halo interference around antibiogram disc is one of the problems seen in Agar media. This study aimed at applying graded plate method to reduce this problem. Material and Methods: Forty-eight millimeter plates, before putting disc, were graded and the location of discs was determined. Instead of full disc, we used half-disc and then compared the haloe interfe...
