Impact of molasses quality on ethyl alcohol fermentation by the yeast saccharomyces cerevisiae
The use of blackstrap cane molasses in industrial ethanol production is characterised by fluctuations in fermentation efficiency due to its compositional variation. Crucial to optimisation of ethanol production is thorough knowledge of the constituents and properties of molasses which affect …

A kinetic study of the base catalyzed esterification of acetic anhydride with ethyl alcohol using a high frequency oscillometer
It is the purpose of this investigation to determine the feasibility of using a 120 megacycle oscillometer for kinetic studies in non-aqueous solutions by studying the reaction rate of the base catalyzed esterification of acetic anhydride.

pH Change Following Smear Layer Removal and Final Rinse with 95% Ethyl Alcohol Using Calcium Hydroxide Medicament or BC Sealer
… external root surface after final rinse of 95% ethyl alcohol using Ultracal XS, Calasept Plus, or obturation with BC sealer. Methods: 80 single rooted extracted human teeth were decoronated with a standardized root length of 15mm. All root were instrumented to size F4 using the ProTaper Gold …

Separation of liquid mixtures by membranes.
… rate of n-heptane and a lower permeation rate of ethyl alcohol than a PES membrane in pervaporation separation of ethyl alcohol/n-heptane mixtures. The second part of this study concerns reverse osmosis of liquid mixtures. A new method to determine the preferential sorption in binary mixtures …

Laboratory experiments on warm fog dissipation.
… use of hygroscopic materials, surfactants and ethyl alcohol. Results indicated that those hygroscopic agents tested, such as NaCl and glycerin, proved to be relatively effective warm fog dispersants compared to distilled water. The ionic and nonionic surfactants tested dissipated warm fog at …

Part I, Preliminary investigation of one-hundred organic compounds as possible colorimetric reagents ; Part II, Solubility of the alkaline earth salts of some higher fatty acids
… acids in the solvents, water, benzene, absolute ethyl alcohol and ether. 2. It has been shown that there is very little difference in the solubility of the different alkaline earth salt of stearic, oleic, linoleic, and linolenic acids in the solvents, water, benzene, absolute ethyl alcohol and …

The influence of pre- and post-mortem treatments of glycogen content and tenderness of poultry muscles
… adrenaline injection, and oral administration of ethyl alcohol. The effect of stretch-tension during rigor on muscle tenderness was also studied. Ante- and post-mortem treatments of the broilers had significant effects upon the rigor patterns, glycogen contents, and tenderness of the poultry meat. …

The design of a thiokol plant
… The information for the design of the ethylene dichloride, the other raw material of Thiokol, was obtained from literature. The studies of the polysulfide solution showed that 13.83 grams of sulfur would react with every 10. 2 grams of caustic when sulfur was in excess. The amount of …

Relative potency and duration of analgesia following palmar digital intra-neural alcohol injection for heel pain in horses
… injection of 98% dehydrated medical-grade ethyl alcohol compared to no treatment (negative control), sham operation (surgical control), or formaldehyde injection (positive control) to decrease experimentally-induced palmar heel pain in horses. Animals: Six horses Procedures: The horses were …

Understanding Red Headed Flea Beetle Biology to Inform Sustainable Pest Management Practices in Virginia Nurseries
… specific population densities. The use of phenyl ethyl alcohol as an attractant lure, was explored to bolster pest control. Finally, insecticide bioassays were performed to compare those currently used to others yet untested.

Studies into Mg-preconditioning of brewer’s yeasts
… yields of ethanol. The specific activity of the alcohologenic enzyme pyruvate decarboxylase was stimulated by Mg enrichment and a correlation between cellular Mg and PDC activity exists. This was especially evident in Mg acetate preconditioned cells. Mg ion homeostasis in Mg non-and …

An Apparatus for Measuring the Vapor Pressure of Liquids by the Gas Saturation Method
… for example, solutions of ammonia in benzene and ethyl alcohol. Since there are no data in the literature for these systems it was decided that an apparatus should be constructed which would give these values with a high degree of accuracy. |The vapor pressure of a liquid may be measured by either …
