Application of Circulation Controlled Blades for Vertical Axis Wind Turbines [PDF]

open access: yesEnergies, 2013
The blades of a vertical axis wind turbine (VAWT) rotor see an inconsistent angle of attack through its rotation. Consequently, VAWT blades generally use symmetrical aerofoils with a lower lift-to-drag ratio than cambered aerofoils tailored to maximise ...

Autonomic Nervous System Regulation of Epicardial Adipose Tissue: Potential Roles for Regulator of G Protein Signaling-4

open access: yesCurrent Issues in Molecular Biology, 2022
The epicardial adipose tissue (EAT) or epicardial fat is a visceral fat depot in the heart that contains intrinsic adrenergic and cholinergic nerves, through which it interacts with the cardiac sympathetic (adrenergic) and parasympathetic (cholinergic ...

Angiotensin and baroreflex control of the circulation [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2002
There is a close association between the location of angiotensin (Ang) receptors and many important brain nuclei involved in the regulation of the cardiovascular system. The present review encompasses the physiological role of Ang II in the brainstem, particularly in relation to its influence on baroreflex control of the heart and kidney. Activation of

Circulation Control of Airfoil Aerodynamic Force Under Ground Effect of Wavy Wall

open access: yesShanghai Jiaotong Daxue xuebao, 2022
The interaction of airflow and sea waves seriously affects the flight stability and cruising safety of ground effect vehicles. The influence of different sea states and different angles of attack were analyzed numerically on the aerodynamic ...

Dynamics of Earth's Hadley Circulation [PDF]

open access: yes, 2013
This thesis advances our understanding of the mechanisms controlling the Hadley circulation, and its interaction with eddies on planetary scales in particular. On Earth, and more generally in a rapidly rotating and differentially heated planet, planetary

Control of the Foetal Circulation [PDF]

open access: yesJournal of Experimental Biology, 1982
ABSTRACT Foetal cardiac output is high, and the heart has not been shown to have the sustained reserves demonstrated in the adult heart. About 40% (∼ 200 ml. kg body weight−1. min−1) of the combined output of both ventricles (CVO) in unanaesthetized foetal lambs in late gestation is directed to the umbilical circulation.

Mechanism of mitigating effect of wheat germ peptides on lead-induced oxidative damage in PC12 cells

open access: yesEcotoxicology and Environmental Safety, 2022
It is well known that lead-induced neurotoxicity is closely related to oxidative stress. According to previous reports, wheat germ peptides (WGPs) isolated from wheat germ have been shown to have potent antioxidant capacity.
