This paper describes three-dimensional (3D) large eddy simulations of stellar surface convection using realistic model physics. The simulations include the present Sun, a subgiant of one solar mass and a lower-gravity subgiant, also of one solar mass. We examine the thermal structure (superadiabaticity) after modification by 3D turbulence, the overshoot of convective motions into the radiative ...

Abstract Due to the eutectic reaction, Mg 2 Si phase is inclined creating an unfavorable fishbone shape at low solidification rates. This can significantly degrade mechanical characteristics and become main barrier practical application of Mg-Si based alloy. It regarded that isothermal semi-solid treatment efficient technique modulate fishbone-shape phases in alloys. In this work, a new type Mg...

Abstract Morphology and structure of starch from fruits two acorns species, Quercus rotundifolia Lam. (QR) suber (QS), isolated by enzymatic (ENZ) alkaline (A3S) methods were studied. Acorn starches granules presented a round oval shape, consisting medium/small granules, with mean granule size ranging between 9 13 µm. Isolated acorn appear as light grayish-brown in naked eye, high values L * fo...

There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...

Small area estimation has received enormous attention in recent years due to its wide range of application, particularly in policy making decisions. The variance based on direct sample size of small area estimator is unduly large and there is a need of constructing model based estimator with low mean squared prediction error (MSPE). Estimation of MSPE and in particular the bias correction of MS...

background quince seed mucilage biopolymer (qsmb), famous for ameliorating coughs and controlling asthma symptoms, has not been processed by scientific methods and rules into a local oral tablet. objectives the purpose of this study was to investigate and compare the mechanical properties of qsmb with different size fractions of the mucilage powder, dried by oven or by freeze drying, to achieve...

In this paper, the spectral dependences of transverse Kerr effect (ТКЕ) are studied experimentally and theoretically. The results obtained for deposited annealed samples with a corresponding variation in size granules. It was found that thermomagnetic annealing leads to an increase ТКЕ value magnetic nanostructures, while most noticeable changes were observed range medium high concentrations co...

The visual system rapidly represents the mean size of sets of objects. Here, we investigated whether mean size is explicitly encoded by the visual system, along a single dimension like texture, numerosity, and other visual dimensions susceptible to adaptation. Observers adapted to two sets of dots with different mean sizes, presented simultaneously in opposite visual fields. After adaptation, t...

Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...
