Outgassing of Ordinary Chondritic Material and Some of its Implications for the Chemistry of Asteroids, Planets, and Satellites [PDF]

, 2006
We used chemical equilibrium calculations to model thermal outgassing of ordinary chondritic material as a function of temperature, pressure, and bulk compositions and use our results to discuss outgassing on asteroids and the early Earth.

High-temperature chemical processing on asteroids: An oxygen isotope perspective [PDF]

, 2005
From the introduction: Small planetary bodies accreted within 2.4 Myr of solar system formation [1]. The primitive materials (CAIs, chondrules, matrix) incorporated into these asteroids were altered by a variety of secondary processes, including aqueous ...

Construction of Lean Coal Molecular Structure Model Based on Spectroscopic Characterization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The chemical structure of coal exerts a profound influence on its properties and utilization pathways. A comprehensive analysis of coal's molecular structure is crucial for mitigating environmental pollution arising from coal combustion and improving the efficiency of coal utilization.

Contact Metamorphism in Southern California [PDF]

, 1954
A highly condensed introduction to "Contact metamorphism in southern California" is obviously not the place in which to indulge in semantic niceties nor to engage in terminological tussles, and thus the title is not intended to reflect a carefully ...

Constraining the long-term evolution of the slip rate for a major extensional fault system in the central Aegean, Greece, using thermochronology [PDF]

, 2006
The brittle/ductile transition is a major rheologic boundary in the crust yet little is known about how or if rates of tectonic processes are influenced by this boundary.

Clock genes regulate Ca2+ signaling and mitochondrial bioenergetics to inhibit Sjogren's disease

Arthritis &Rheumatology, Accepted Article.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjogren's disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA seq, and mitochondrial activity were used to investigate the effects of ...

A matter of time: The importance of the duration of UHT metamorphism

, 2016
The duration of granulite (G) and ultra – high temperature (UHT) conditions in regional metamorphism is critical to arguments regarding the tectonic settings of granulites and their relationships to Supercontinent assembly.
