Testing Water Regulation
نویسنده
چکیده
A complex regulatory system is responsible for the stability of plasma osmolality despite large variations in water consumption or water loss. This osmoregulatory system is controlled by the hypothalamic neurohypophyseal axis, which includes the organs responsible for sensing variations in plasma osmolality or volume, as well as for the synthesis, storage, and secretion of arginine vasopressin (AVP), the antidiuretic hormone. The osmoregulatory system also includes osmoreceptors of thirst, which control drinking behavior. The osmoreceptors are also stimulated by osmotic changes in plasma. The second component of the osmoregulatory system involves the kidney. The renal collecting duct is sensitive to the action of AVP. In response to AVP, the functional units of the kidney allow dramatic variations in urinary flow in order to maintain water balance. In order to test water regulation, it is therefore necessary to evaluate not only vasopressin secretion and sensitivity of the kidney to vasopressin, but also thirst.

متن کاملEstimating of Scour in Downstream of the Water Level Regulation Structures
Scour in the downstream of hydraulic structures is a phenomenon which usually occurs due to exceeding the velocity or shear stress from a critical level. In this paper by using the laboratory data by Borman- Jouline and De-Agostino research, it was tried to get more accurate equations in order to calculate the maximum depth of scour in the downstream of the water level regulation structures. Co...
