Explosion Temperatures of Metals and Other Elemental Dust Clouds
The Pittsburgh Research Laboratory of the National Institute for Occupational Safety and Health conducted a study of the explosibility of various metals and other elemental dusts dispersed in air, with a focus on the experimental explosion temperatures. The data are useful for understanding the basics of dust cloud combustion, as well as for evaluating the explosion hazards in the minerals and ...

متن کاملFurther studies of the dust in lungs of coal-miners.
In a previous communication (King and Nagelschmidt, 1945), analytical data were given for the amount and composition of the dust found in the lungs of 54 coalworkers from South Wales. Coal, total silica, quartz, mica, and kaolin were determined as the percentages of dried lung tissue, and the results were related to type of work and degree of pathology. The main findings were the following: (1)...

this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
15 صفحه اولExplosion dust particle size measurements.
In situ measurements of the sizes and concentrations of dust particles generated by the detonation of high explosives in clay soil near Leesville, La., sandy clay soil near Huntsville, Ala., and sandy soils near Orogrande, N.M. are reported. Measurements were generally made within 1 m of the surface (in one case 10 m) at distances ranging from 10 to approximately 50 m from the detonation point ...
