Anatomical airways parameters, such as length, diameter and angles, have a strong effect on the flow dynamics. Aiming to explore of variations bifurcation angle (BA) carina rounding radius (CRR) lower human respiratory processes, numerical simulations airflow during inhalation exhalation were performed using synthetic models. Geometries for models parameterized based set different BA’s several ...

The study of the effect chitosan succinate use on hematological indicators dairy cows is relevant. It has been established that there was a clear tendency to increase in number white blood cells by 10.12% animals group 3 (P < 0.1) 10th day experiment receiving low-molecular-weight succinate, second this indicator 2.94% unreliable. On 20th experiment, an intensive observed both experimental g...
