On September 16, 2013, the North Carolina Division of Public Health was notified of an elemental (metallic and liquid) mercury spill on a school bus. An elementary student boarded the bus with approximately 1 pound (454 g) of elemental mercury contained in a film canister, which the student had taken from an adult relative who had found it in a neighbor's shed. The canister was handled by sever...

Organosulfur compounds (OSCs) are naturally emitted via various processes involving phytoplankton and algae in marine regions, from animal metabolism, and from biomass decomposition inland. These compounds are malodorant and reactive. Their oxidation to methanesulfonic and sulfuric acids leads to the formation and growth of atmospheric particles, which are known to influence clouds and climate,...

We perform experiments and discrete element simulations on the dosing of cohesive granular materials in a simplified geometry. The setup is a canister box where the powder is dosed out through the action of a constant-pitch coil feeder connected to a motor. A dose consists of a rotation followed by a period of rest before the next dose. From the experiments, we report on the operational perform...

so portable, that it would be most useful on field service. It is prepared from green mangoes. The unripe fruit is cut into several pieces and dried in the sunshine, the kernel and peel being rejected. In this state it is Kuttaicalled huttai, (emphasis on last syllable,) but to preserve it properly, it must be ponnded to a fine powder, and rammed into an air-tight tin canister, or wide-mouthed ...

An intercomparison exercise for passive integrating radon detectors has been carried out with the participation of 12 detection systems from 10 laboratories. The detection systems comprise three commonly used in radon integrating measurements, tracks, activated charcoal canisters and electrets. The exposures were carried out in the radon and thoron chambers at the Institute of Energy Techniques...

Various canister candidate materials (SS316L, Ti-Gr.2, Alloy 22, and Cu) were studied using groundwater at the Korea Atomic Energy Research Institute (KAERI) underground research tunnel (KURT), with addition of chloride ions different electrochemical techniques. The corrosion potential current test obtained by polarization measurement. measurements revealed that was detrimental to SS316L Cu inc...

BACKGROUND Many chemical agents used in liquid crystal display (LCD) manufacturing have been evaluated in animal studies of female reproductive toxicity. Knowledge of their reproductive toxicity in humans is scant. AIMS To determine the effect of organic solvents on menstrual cycle characteristics of workers in LCD manufacturing. METHODS Cross-sectional study of female premenopausal workers...

Noise pollution is one of the common physical harmful factors in many work environments. The current study aimed to assess personal and environmental sound pressure level project sound-Isosonic map Razavi Khorasan Paste manufacture using Surfer V.14 at V.5.0. This cross-sectional, descriptive analytical that was conducted 2018 factory contains Canister, production Brewing unit. Following ISO 96...
