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.

Received: 26 September 2018; Accepted: 10 October 2018; Published: 13 October 2018 Abstract: In this work, nanosized Cu and Ni Schiff-base complexes, namely ahpvCu, ahpnbCu, and ahpvNi, incorporating imine ligands derived from the condensation of 2-amino-3-hydroxypyridine, with either 3-methoxysalicylaldehyde (ahpv) or 4-nitrobenzaldehyde (ahpnb), were synthesized using sonochemical approach. The structure and properties of the new ligands and their complexes with Ni(II) and Cu(II) were determined via infrared (IR), nuclear magnetic resonance (NMR), electronic spectra (UV-Vis), elemental analysis (CHN), thermal gravimetric analysis (TGA), molar conductivity (Lm), and magnetic moment (meff). The combined results revealed the formation of 1:1 (metal: ligand) complexes for ahpvCu and ahpvNi and 1:2 for ahpnbCu.

To investigate the migration and release behavior of the monomers from melamine-based food contact materials into food simulants and food stuffs, cooking spoons were tested under so-called hot plate conditions at 100 ◦C. Release conditions using the real hot plate conditions with 3% acetic acid were compared with conditions in a conventional migration oven and with a release to deionized water. Furthermore, the kinetics of the release were studied using Arrhenius plots giving an activation energy for the release of melamine of 120 kJ/mol. Finally, a correlation between quality of the resins, specifically the kind of bridges between the monomers, and the release of melamine, was confirmed by CP/MAS 13C-NMR measurements of the melamine kitchenware. Obviously, the ratio of methylene bridges and dimethylene ether bridges connecting the melamine monomers during the curing process can be directly correlated with the amount of the monomers released into food.

The polyethylene glycol allyl glycidyl ether (PGAGE) is an important intermediate for preparing silicone softener that can be synthesized from allyl alcohol polyoxyethylene ether and epichlorohydrin (ECH). The performance parameters including the concentration of ECH, initial boron trifluoride diethyl etherate (BFEE) as well as CaCl2 quality were investigated respectively. The optimum process parameters which can get high capping and low by-product rate are as follows: the ECH concentration is 2.0 M, the initial BFEE concentration is 1.65mM, and the CaCl2 dosage is 1.65g/L. Under these conditions, the maximal yield can be improved to 91.36%, the percent of capping rate is higher than 98.16%, the residual concentration of F- is only 0.63 mg/L. concentrated basic solution, in which the total yield was between 90%~91% by Matsuoka et al.

Preface One of the primary goals of WHO and its member states is that “all people, whatever their stage of development and their social and economic conditions, have the right to have access to an adequate supply of safe drinking water.” A major WHO function to achieve such goals is the responsibility “to propose ... regulations, and to make recommendations with respect to international health matters ....” The first WHO document dealing specifically with public drinking-water quality was published in 1958 as International Standards for Drinking-water.

Figure 1. Sample preparation for the dwell time test. Section 3 Thickness measurement of coated PCBs Materials and Equipment Printed circuit boards (PCB), acrylic conformal coating, tape, Dektak stylus profiler (Bruker, Arizona, USA). Methods A piece of tape was attached on a PCB before coating. The coating was applied on the PCB using the same method as dip coating in the dwell time test. The PCB was sta- tioned and dried at room temperature for over 24 hours. The tape was then torn out to create a coating step. The PCB was fixed on the detection table using tapes. The stylus scanned from sub- strate to coated area.

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.
