AND ASTROPHYSICS Atomic diffusion in star models of type earlier than G
We introduce the mixing resulting from the radiative diffusivity associated with the radiative viscosity in the calculation of stellar evolution models. We find that the radiative diffusivity significantly diminishes the efficiency of the gravitational settling in the external layers of stellar models corresponding to types earlier than ≈ G. The surface abundances of chemical species predicted ...
متن کاملAtomic diffusion modeling and Investigation of joining properties of TLP in AA2024 to AA6061 alloys
In this study, to bond AA2024 and AA6061 alloys to each other, three elements (Sn, Zn and Ga) were considered as interlayer elements in terms of atomic diffusion depth in the base metal and storage at 453°C for 2 days, 10 hours, 210 minutes, and 30 seconds that they were examined for atomic diffusion modeling. Finally, the two alloys were connected at a temperature of 453°C in a furnace enviro...

متن کاملChange in the Cortical Complexity of Spinocerebellar Ataxia Type 3 Appears Earlier than Clinical Symptoms
Patients with spinocerebellar ataxia type 3 (SCA3) have exhibited cerebral cortical involvement and various mental deficits in previous studies. Clinically, conventional measurements, such as the Mini-Mental State Examination (MMSE) and electroencephalography (EEG), are insensitive to cerebral cortical involvement and mental deficits associated with SCA3, particularly at the early stage of the ...
متن کاملFull-star Type Ia supernova explosion models
We present full-star simulations of Type Ia supernova explosions on the basis of the standard Chandrasekhar-mass deflagration model. Most simulations so far considered only one spatial octant and assumed mirror symmetry to the other octants. Two full-star models are evolved to homologous expansion and compared with previous single-octant simulations. Therefrom we analyze the effect of abolishin...
