3-D GCM modelling of thermospheric nitric oxide during the 2003 Halloween storm
Numerical modelling of thermospheric temperature changes associated with periods of high geomagnetic activity are often inaccurate due to unrealistic representation of nitric oxide (NO) densities and associated 5.3-μm radiative cooling. In previous modelling studies, simplistic parameterisations of NO density and variability have often been implemented in order to constrain thermospheric temper...
متن کاملHalloween Storm Simulations with the Space Weather Modeling Framework
In late October and early November 2003 a series of some of the most powerful solar eruptions ever registered shook the heliosphere. These “Halloween storms” damaged 28 satellites, knocking two out of commission, diverted airplane routes and caused power failures in Sweden, among other problems. Long-distance radio communications were disrupted because of the effects on the ionosphere, and nort...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Nitric oxide and the bioactivities
Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...
