Density of Molten “ Apollo 17 Orange Glass ”

Introduction: Modelling the dynamic evolution of the interior of the Moon is intrinsically linked to the density of lunar materials at high pressures and temperatures. Lunar magma density variations during crystallisation of the lunar magma ocean are particularly important, since the formation of plagioclase-rich highland rocks and mare basalts are related to density differences between lunar m...

With our plans for returning humans to the Moon, it is paramount to address these issues. For example, an embarrassing problem involved the fact that none of the ‘Milliondollars rock boxes’ built at Oak Ridge National Lab remained sealed at the vacuum of the Moon...

Photoelectric Emission Measurements on Apollo 17 Lunar Dust Grains:

Introduction: The deleterious effects of the ubiquitous presence of small micron/sub-micron size dust grains in the lunar surface environment are recognized to be one of the major issues that must be addressed in planning the forthcoming missions for robotic and human exploration of the Moon. On theoretical considerations as well as observational evidence, it has been well accepted since the Ap...

O-GlcNAc: A Bittersweet Switch in Liver

The liver is a vital organ responsible for maintaining nutrient homeostasis. After a meal, insulin stimulates glycogen and lipid synthesis in the liver; in the fasted state, glucagon induces gluconeogenesis and ketogenesis, which produce glucose and ketone bodies for other tissues to use as energy sources. These metabolic changes involve spatiotemporally co-ordinated signaling cascades. O-linke...
