Numerical simulation of flow hydrodynamic around dolphin body in viscous fluid
The biomimetic and hydrodynamic study of aquatic animals is one of the most challenging computational fluid dynamics topics in recent studies due to the complexity of body geometry and the type of flow field. The movement of the aquatic body, and particularly the tail section and the corresponding movement of fluid around the body, causes an unsteady flow and requires a comprehensive study of t...
متن کاملP-79: The Effect of Alkaline Environments Made with Calcium Carbonate in Order to Migration Spermatozoa for Sex Selection
Background: Due to different such as some sexrelated illnesses, spouses have been encourage to designate special treatments for assessing sexuality. Moreover, Utilizing from identifying sexulityb has been an important aim in industry in order to product humans needs and develop cattle. In this research, the effect of alkaline environments were examined migration spermatozoa for sex selection. M...
متن کاملP-80: The Effect of Alkaline Environments Made with Sodium BiCarbonate in order to Separate Spermatozoa for Sex Selection
Background: There are different factors Tahat effect in sex selection such as the best medium treatment.These techniques can be used in live stock industry for product in ordre to humans need. Materials and Methods: Forty mice (NMRI) were divided in to a control group and three experimental group. Ovulation of mice was stimulated by using PMSG and HCG hormones. Female mice were killed by cervic...
متن کاملMechanochemical Coupling in Flagella
The relation between oxygen consumption and motility of Ciona spermatozoa has been measured by using pH stats to measure the acid production of spermatozoa swimming in dilute suspensions where their motility can be analyzed accurately, and calibrating the acid production by measuring it simultaneously with measurements of oxygen consumption, using more concentrated sperm suspensions. When the m...
متن کاملLearning to move amid uncertainty.
We studied how subjects learned to make movements against unpredictable perturbations. Twelve healthy human subjects made goal-directed reaching movements in the horizontal plane while holding the handle of a two-joint robotic manipulator. The robot generated viscous force fields that perturbed the limb perpendicular to the desired direction of movement. The amplitude (but not the direction) of...
