Acetone : a system call interface for Asbestos labels
Acetone is a secure operating system kernel that uses a shared address space and supports Asbestos labels. Acetone uses Asbestos labels to enable a wide variety of security policies including ones that prevent untrusted applications from being able to disclose private data. All threads run in the …

Ozone Decomposition and Acetone Oxidation on Manganese Oxide Catalysts
… and their application in the oxidation of acetone, a typical volatile organic compound (VOC), and ozone decomposition. This topic is of great value because of environmental concerns of the elimination of the harmful VOCs and ozone. Manganese oxide was chosen because it is a well-known …

Physico-chemical studies of solutions of some acids in acetone
… of knowledge of the behaviour of electrolytes in acetone solutions as well as the uncertainty as to the possibility of preparing anhydrous acetone and the stability of this solvent, if it could be prepared. An extensive study was therefore undertaken in which the efficiency of various desiccants …

The effects of acetone shock loading on phenol acclimated cultures
The possibility of acetone shock loadings to phenol acclimated systems resulting in sequential substrate utilization and increased effluent phenol concentrations was evaluated. Phenol acclimated batch and continuous-flow systems, developed with seed from a municipal wastewater treatment plant, were …

Quantitative Acetone PLIF Measurements of Jet Mixing with Synthetic Jet Actuators
… using planar laser-induced fluorescence of acetone. The synthetic jets are a promising new mixing control and enhancement technology with a wide range of capabilities. An image correction scheme that improved on current ones was applied to the images acquired to generate quantitative mixing …

Acetone, Butanol, and Ethanol (ABE) Production from Food Waste via Clostridium beijerinckii
… pollution. Fermentation of food waste to produce acetone, butanol and ethanol (ABE) via fermentation has the potential to valorize food waste by producing value-added chemicals. However, the composition of food wastes from different sources vary, which affects ABE fermentation performance and …

Production of acetone and butanol by Clostridium acetobutylicum using free and immobilized cells
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Nutrition and Food Science, 1982.

A kinetic study of the transfer of acetone between toluene and water phases
… of chemical kinetics to the transfer of acetone between water and toluene phases, and thereby attempt to develop mechanisms and evaluate resistances to such transfer. An extraction cell was constructed which consisted of a 20-liter glass battery jar with independently driven impellers in …

Mathematical modeling of the acetone-butanol fermentation for the purposes of bioreactor design
The acetone-butanol fermentation by Clostridium acetobutylicum is receiving renewed interest as a process for large scale solvent production. The fermentation kinetics have been modeled as functions of substrate, butyrate, and butanol concentrations and pH. These models have been applied to …

Electrolytic conductances and related properties of solutions of some acids and salts in acetone
… of various methods of preparing pure, anhydrous acetone has been made (cf. Sadie), no investigations of methods for determining the moisture content of this solvent have previously been described. A solvent with a consistently low water content is essential for electrochemical measurements. …

A reassessment of the production of acetone and butanol by Clostridium acetobutylicum in continuous culture
The production of acetone and butanol by Clostridium acetobutylicum P 262 was studied in continuous culture under conditions where the nutrients were present in excess of the requirements and the cell growth was limited by the products formed during the fermentation. This system differs from most …

Evaluation of the Chlorophyll/Fluorescence Sensor of the YSI Multiprobe: Comparison to an Acetone Extraction Procedure
… and examining the precision and linearity of the acetone extraction procedure. Cell disruption by mortar and pestle grinding was preferable to bath sonication. Comparison of the chlorophyll/fluorescence readings from the multiprobe and the extraction procedure indicated that they were …

Spray and combustion characteristics of acetone-butanol-ethanol and diesel in a constant volume chamber and a diesel engine
… the high cost of the butanol production process. Acetone-butanol-ethanol (ABE) is an intermediate product of the fermentation process of butanol production. By eliminating the separation and purification processes, using ABE directly in diesel blends has the potential of greatly decreasing the …

Physiological Changes Occurring in the Cellular Membranes of Clostridium Acetobutylicum ATCC 824 and a Butanol-Tolerant Mutant During the Acetone-Butanol-Ethanol Fermentation
The acetone-butanol-ethanol fermentation by Clostridium acetobutylicum is not able to compete economically with the petroleum methods, due to the premature termination of this fermentation from the butanol produced by the cell. It is known that alcohols disrupt the membrane structure and function, …
