The condensational growth of submicrometer aerosol particles to climate relevant sizes is sensitive to their ability to accommodate vapor molecules, which is described by the mass accommodation coefficient. However, the underlying processes are not yet fully understood. We have simulated the mass accommodation and evaporation processes of water using molecular dynamics, and the results are comp...
This study aimed to compare growth indices and production of rainbow trout breeders (Oncorhynchus mykiss) without any specific pathogens in various populations at the Fishery Research Center of Coldwater-Tonekabon. The project's implementation included collecting Pre-breeders were done in selected rainbow trout breeding centers (based on the approval of the Iranian Fisheries Organization and th...
For several years, progress has been made in understanding surface melting as well as surface roughening of various crystals such as ice, lead, rare gases etc. A so-called quasi-liquid layer (QLL), caused by surface melting, is expected to influence the vapor growth mechanism of crystals at temperatures not far below their melting points. The effect of the self-diffusion coefficient D of a QLL ...
In longitudinal research, interest often centers on individual trajectories of change over time. When there is missing data, a concern is whether data are systematically missing as a function of the individual trajectories. Such a missing data process, termed random coefficient-dependent missingness, is statistically non-ignorable and can bias parameter estimates obtained from conventional grow...
