Ground Squirrel Behaviour During a Partial Solar Eclipse

Solar radiation during a total solar eclipse

Coordinated weather balloon solar radiation measurements during a solar eclipse

Solar eclipses provide a rapidly changing solar radiation environment. These changes can be studied using simple photodiode sensors, if the radiation reaching the sensors is unaffected by cloud. Transporting the sensors aloft using standard meteorological instrument packages modified to carry extra sensors, provides one promising but hitherto unexploited possibility for making solar eclipse rad...

Uptake in Ground Squirrel Brain during Hibernation’

Autoradiographic patterns of [14C]2-deoxyglucose uptake are described throughout the brains of hibernating and euthermic ground squirrels. Autoradiographs of the brains of hibernating animals are generally homogeneous in comparison to euthermic animals; hence, the relative 2-deoxyglucose uptake (RBDGU) of gray to white matter for the majority of the 85 neural structures examined decreases durin...

Charging Behaviour of Solar Panel Polyimide Components during Satellite Eclipse Events in Geostationnary Radiation Environment

This paper presents experimental results carried out in the SIRENE irradiation test facility, installed at ONERA (Toulouse, France), on stacked polyimide / adhesive structures used on solar panels. This study aims at following the evolution of the charging potential built up at the surface of these structures during an eclipse event in geostationary orbit. We have been able to demonstrate that ...
