Effect of Diethylenetriamine and Triethylamine Sensitization on the Critical Diameter of Nitromethane’
CP505, Shock Compression of Condensed Matter - 1999 edited by M. D. Furnish, L. C. Chhabildas, and R. S. Hixson 0 2000 American Institute of Physics l-56396-923-8/00/$17.00 EFFECT OF DIETHYLENETRIAMINE AND TRIETHYLAMINE SENSITIZATION ON THE CRITICAL DIAMETER OF NITROMETHANE’ J.J. Lee*, J. Jiang?, K.H. Choong’, J.H.S. Lee’ *Graduate Aeronautics Laboratory, California Institute of Technology, Pasadena, CA 9112.5, USA ‘Dept. of Mechanical Engineering, McGill University, Montr&al, Que’bec, Canada, H3A 2K6 In this work, the critical diameter for detonation was measured for Nitromethane (NM) sensitized with two different amines: Diethylenetriamine (DETA) and Triethylamine (TEA). The critical diameter in glass and polyvinylchloride tubes is found to decrease rapidly as the amount of sensitizer is increased, then increase past a critical amount of sensitizer. Thus the critical diameter reaches a minimum at a critical concentration of sensitizer. It was also found that the critical diameter is lower with DETA than with TEA. INTRODUCTION propagation in various tubes and channels, and the critical conditions for propagation in porous media Previous studies have shown that small (3) . concentrations of certain substances can strongly The effect of DETA on the critical diameter of increase the explosive sensitivity nitromethane NM has been reported by Engelke (4), who (NM). Amines are found to be the most effective performed measurements with up to 2.5% DETA by chemical sensitizing agent for NM with mass in NM. Engelke observed a reduction in the ethylenediamine and diethylenetriamine (DETA) critical diameter of over 50% in the range of DETA producing the largest increase in the card gap value concentrations used. -
How to Take Your Phosphate Binders
How to take your phosphate binders Information for renal patients Oxford Kidney Unit Page 2 What are phosphate binders? To reduce the amount of phosphate you absorb from your food you may have been prescribed a medicine called a phosphate binder. Phosphate binders work by binding (attaching) to some of the phosphate in food. This will reduce the amount of phosphate being absorbed into your blood stream. A list of phosphate binders and how to take them is shown below. Phosphate binder How to take it Calcichew (calcium carbonate) Chew thoroughly 10-15 minutes before or immediately before food Renacet (calcium acetate) Phosex (calcium acetate) Osvaren (calcium acetate and magnesium carbonate) Swallow whole after the first Renagel 2-3 mouthfuls of food (sevelemer hydrochloride) Renvela tablets (sevelemer carbonate) Alucaps (aluminium hydroxide) Renvela powder Dissolve in 60ml of water and (sevelemer carbonate) take after the first 2-3 mouthfuls of food Fosrenol tablets Chew thoroughly towards the (lanthanum carbonate) end/immediately after each meal Fosrenol powder Mix with a small amount of (lanthanum carbonate) food and eat immediately Velphoro Chew thoroughly after the first (sucroferric oxyhydroxide) 2-3 mouthfuls The phosphate binder you have been prescribed is: ……………………………………………………………………………………………………………………………………………………….. Page 3 How many phosphate binders should I take? You should follow the dose that has been prescribed for you. Your renal dietitian can advise how best to match your phosphate binders to your meal pattern, as well as which snacks require a phosphate binder. What happens if I forget to take my phosphate binder? For best results, phosphate binders should be taken as instructed. -

Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

Effect of Enzymes on Strawberry Volatiles During Storage, at Different Ripeness
Effect of Enzymes on Strawberry Volatiles During Storage, at Different Ripeness Level, in Different Cultivars and During Eating Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Gulsah Ozcan Graduate Program in Food Science and Technology The Ohio State University 2010 Thesis Committee: Sheryl Ann Barringer, Adviser W. James Harper John Litchfield 1 Copyright by Gülşah Özcan 2010 ii ABSTRACT Strawberry samples with enzyme activity and without enzyme activity (stannous chloride added) were measured for real time formation of lipoxygenase (LOX) derived aroma compounds after 5 min pureeing using selected ion flow tube mass spectrometry (SIFT-MS). The concentration of (Z)-3-hexenal and (E)-2-hexenal increased immediately after blending and gradually decreased over time while hexanal concentration increased for at least 5 min in ground strawberries. The formation of hexanal was slower than the formation of (Z)-3-hexenal and (E)-2-hexenal in the headspace of pureed strawberries. The concentration of LOX aldehydes and esters significantly increased during refrigerated storage. Damaging strawberries increased the concentration of LOX aldehydes but did not significantly affect the concentration of esters. The concentrations of many of the esters were strongly correlated to their corresponded acids and/or aldehydes. The concentration of LOX generated aldehydes decreased during ripening, while fruity esters increased. Different varieties had different aroma profiles and esters were the greatest percentage of the volatiles. The aroma release of some of the LOX derived aldehydes in the mouthspace in whole strawberries compared to chopped strawberries showed that these volatiles are formed in the mouth during chewing. -

Clinical Relevance and Summary of Test Principle a. Clinical Relevance The prevalence of disinfection by-products in drinking water supplies has raised concerns about possible adverse health effects from chronic exposure to these potentially carcinogenic compounds. To support studies exploring the relation between exposure to trihalomethanes (THMs), nitromethane (NM: biomarker for halonitromethanes), methyl tert-butyl ether (MTBE) and adverse health effects, an automated analytical method was developed using capillary gas chromatography (GC) and high-resolution mass spectrometry (MS) with selected ion mass detection and isotope-dilution techniques. -
