TL;DR: In this article, a re-evaluation of the raw data of previously published acute inhalation toxicity studies of some volatile industrial chemicals is presented, and the results show that the product of concentration and exposure time (ct ) is not always a good parameter for predicting the mortality response.

TL;DR: In this article, chemical methods were evaluated for the treatment of 1, 4-dioxane in industrial process wastewaters, and it was found that hypochlorous acid was the preferred oxidant.

TL;DR: The argument is made that H,S affects the carotid sensors in the same manner as reduced oxygen tension, thus resulting in increased rate and depth of ventilation, so resulting in hyperpnea at sublethal exposures.

TL;DR: In this article, the biodegradability of 78 priority organic compounds were tested with an electrolytic respirometer under the standard conditions determined in the preceding paper, and the results were discussed from the structures of the organic compounds and conventional knowledge on biodegradation mechanisms.

TL;DR: In this article, five characteristic indexes of the biodegradability of eleven principal organic compounds were obtained from the biochemical oxygen demand (BOD) curves and dissolved organic carbon (DOC) measurements.

TL;DR: In this article, a method for recrystallization of HMX from γ-butyrolactone has been developed, which produces well-shaped crystals of the desired β-modificati

TL;DR: In this article, a research project was undertaken to learn how the highly acute olfactory sensitivity of the canine could be applied with advantage to environmental problems, and three dogs were trained to recognize and locate chemicals selected from the toxic and hazardous chemical lists.

TL;DR: The coating of high explosives is a very important technique for lowering the sensitivity of explosives as discussed by the authors, and different methods for coating explosives with different materials are discussed in detail in the literature.

TL;DR: In this article, it was shown that the restriction of the inverse square law for the decay of the intensity of the physical effect can be relaxed and that for the more general case where the decay is inversely proportional to some power n of the distance, the correction factor is o= exp (σ2/n2), where σ is the spread parameter of the lognormal distribution.

TL;DR: In this article, an analytical model is developed to predict desorption fluxes on the basis of the contamination scenario, the conditions external to the contaminated material and physical properties as determined by independent tests.

TL;DR: In this article, a two-dimentional finite difference model was used to simulate an explosion in a pit and to determine to what extent the blast wave was attenuated by the presence of a pit in all cases, and a useful parameter, dEout/dt, was shown to be a good indicator of relative pit effectiveness.

TL;DR: Instrumentation that provides trace organic analysis for complex polymer and nitramine-containing materials has been shown effective in many studies [1, this paper, [2] and [3].

TL;DR: In this article, chemical and photographic analyses perfomed on 112 explosive transfer lines used to initiate aircraft emergency escape systems were performed on a single aircraft, and the results showed that these lines can be used for emergency escape.

TL;DR: The transportation of hazardous materials occurs in the context of a complex and dynamic institutional environment as mentioned in this paper, which includes concerns over protection of public health and the environment, institutional issues include discussions of appropriate division of political authority and responsibility, trust in diverse political authorities, and financial liability and the provision of sufficient emergency response capabilities in the event of transport accidents.

TL;DR: In this article, the order of sensitivity in the falling weight test is calculated as a function of bubble size for a liquid explosive/bubble system, and the results compare favorably with experiments, and indicate that sensitivity in such cases is not some unique property of the liquid explosive itself, but rather is a property of a liquid/bubble system.

TL;DR: In this article, the effects of dissolved manganese and chromium species on the rate of homogeneous decomposition of a homogeneous polygonal decomposition was investigated and experiments were described which seek to establish the effect of these species on decomposition.

TL;DR: A study of the polymerization of a number of monomers and a variety of known absorbents has been carried out using the technique of accelerating rate calorimetry as mentioned in this paper.

TL;DR: In this article, the authors assessed current fail-safe technology, conducted laboratory tests of automatic devices and monitored performance of on-site automatic level controllers. But they did not consider the use of automatic level detectors for either wet or dry products.

TL;DR: The RR119 decoy flare as mentioned in this paper is a consolidated composition of magnesium, Teflon and binder, approximately 2.5 in. × 3 in. in size and weighs approx.

TL;DR: In this article, a two-phase study of the combustion of solvents carried in large quantity by rail was performed, where the first phase involved development of protocol and apparatus for determining the amounts of soot produced and heats of combustion for several commonly carried commodities under varying conditions of oxygen availability.

TL;DR: The apparatus and protocols used to determine the semi-volatile products of combustion from controlled laboratory-scale fires are presented in this article, where the results for sixteen solvents commonly carried by rail are presented.

TL;DR: In this paper, a dummy variable analysis of covariance is suggested as a desirable alternative to the Student's t-test for evaluating groundwater pollution detection parameters, and the average of the upgradient and downgradient wells are compared.

TL;DR: In this article, the cupric chloride effect on the viscosity of nitrocellulose (NC) in acetone solution was studied for various wood and cotton NCC samp.

TL;DR: In this article, a used solvent elimination (USE) program at the Naval Ordnance station (NASTA) was investigated in terms of technical, economic, and safety considerations.
