Effect of Diethylenetriamine and Triethylamine Sensitization on the Critical Diameter of Nitromethane’

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. -

Dr. von Karman gathered about him a group of Ameri can scientists from every field of research having a bearing on air power. These men then analyzed im portant developments in the basic sciences, both here and abroad, and attempted to evaluate the effects of their application to air power.

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. -

FIA Technical Regulations for Drag Racing
FIA DRAG RACING SECTION 1 - JUNIOR DRAGSTER & JUNIOR FUNNY CAR 2021 Specific Regulations for FIA Drag Racing These Technical Regulations provide guidelines and minimum standards for the construction and operation of vehicles used in FIA Drag Racing. It is the responsibility of the participant to be familiar with the contents of these Technical Regulations and to comply with its requirements. It is not the responsibility of the officials to discover all potential rule compliance issues. The responsibility for compliance with these Technical Regulations rests first and foremost with the competitor. Additional safety equipment or safety-enhancing equipment is always permitted and the levels of safety equipment stated in these Technical Regulations are minimum prescribed levels for a particular type of competition and do not prohibit the individual competitor from using additional safety equipment. Competitors are encouraged to investigate the availability of additional safety devices or equipment for their type of competition. In disputed cases, whether an item, device or piece of equipment is safety-enhancing or performance-enhancing will be determined by the FIA Technical Delegate or the FIA Technical Department. Furthermore, as to performance-enhancing equipment, it is the general principle that unless optional performance-enhancing equipment or performance- related modifications are specifically permitted by these Technical Regulations, they are prohibited. Throughout these Technical Regulations, a number of references are made for particular products and equipment to meet certain standards and specifications (i.e. FIA-Standard, SFI Specs, Snell, DOT, etc.). It is important to realize that these products are manufactured to meet certainspecifications, and upon completion, the manufacturer labels the product as meeting that standard or specification. -
Tnt Equivalence of C-4 and Pe4: a Review of Traditional Sources and Recent Data
TNT EQUIVALENCE OF C-4 AND PE4: A REVIEW OF TRADITIONAL SOURCES AND RECENT DATA D. Bogosian1, M. Yokota1, S. Rigby2 1Baker Engineering and Risk Consultants, 360 N. Sepulveda Blvd., Ste 1090, El Segundo, CA 90245, USA; 2University of Sheffield, Department of Civil & Structural Engineering, Sir Frederick Mappin Building, Mappin Street, Sheffield, S1 3JD, United Kingdom ABSTRACT Since standard engineering-level blast models are typically developed to predict airblast parameters (pressure and impulse) from TNT bursts, prediction of airblast from other materials uses an equivalence factor by which an equivalent TNT weight is computed and used in the source term of the model. This approach is widespread in the industry and has been codified in numerous manuals, books, and papers. A recent effort co-sponsored by TSWG (U.S.) and FSTD (Singapore) collected and compiled equivalence data for a wide variety of explosive materials (both military grade as well as home-made) into a single software tool named STREET. The database thus assembled provides a comprehensive and expandable repository for equivalence data. Two of the main achievements in STREET are the consideration of equivalence as a function of scaled standoff (rather than a scalar), and the documentation of uncertainty in the estimated value. In this paper, we consider specifically the manual- and test-derived data related to Composition C-4, and as a first step, we draw some judgments regarding the equivalence implicit in blast curves provided by UFC 3-340-02, for both pressure and impulse. Next, we consider PE4, which is similar in composition to C-4 and is used widely in the UK. -
