With the rapid development of 3D printing technology, printers have been applied in many fields. However, with resin or plastic wires produce toxic exhaust (mainly VOCs), which may pose a great threat to human body and environment. In order solve problems above, this paper proposes method treating gas by using heat-excited oxide semiconductors, designs device for waste gas. From aspects force, ...

The purpose of this research is to evaluate the effectiveness of implementation Quality Management System (ISO 9001:2000) in gas processing plants of National Iranian Gas Company using balanced scorecard approach. More specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in National Iranian Gas Company from four different perspectives in order...

There is growing interest in the health and environmental benefits of whole-food plant-based (WFPB) diets. The current global food system harmful to our planet a key driver climate change, pollution biodiversity loss. A transition WFPB diets will mitigate against these impacts potentially reduce agriculture greenhouse gas emissions by up 80%. Emerging evidence suggests that such also have signi...

1. Three experiments have been designed to test the following assumptions underlying the conventional methods for calculating decompression schedules : (a) that there is a critical limit to the supersaturation of a tissue by a gas, and (b) that no gas is formed in the tissues of a subject who does not develop symptoms of decompression sickness. 2. When decompression time was titrated by cutting...

OBJECTIVES Evaluate upper-limb goal attainment following botulinum toxin-A, map goals to the International Classification of Functioning, Disability and Health (ICF) and explore associations between client goals, clinical indicators of spasticity and the Botulinum Toxin-A injection strategy adopted by the treating physician. DESIGN Pre-test/post-test. PARTICIPANTS Twenty-eight community-dwe...

High rate algae ponds fed clarified domestic wastewater and CO2-rich flue gas are expected to remove nutrients to concentrations similar to those achieved in mechanical treatment technologies, such as activated sludge. However, the energy intensity of wastewater treatment with CO2-supplemented high rate ponds (HRPs) would be less than that of mechanical treatments. In conjunction with anaerobic...

A detailed analysis of a biotrickling filter treating trichloroethene (TCE) vapors anaerobically is presented and discussed. The biotrickling filter relies on mixed cultures containing bacteria from the genus Dehalococcoides that reductively dechlorinate TCE to ethene. After about 200 days of steady operation, as biomass in the packed bed increased, a partial loss in treatment performance was o...

Biofiltration of waste gases is cost-effective and environment-friendly compared to the conventional techniques for treating large flow rates of gas streams with low concentrations of pollutants. Pulp and paper industry off-gases usually contain reduced sulfur compounds, such as hydrogen sulfide and a wide range of volatile organic compounds (VOCs), e.g., methanol. It is desirable to eliminate ...

AIM An increase in intestinal gas production due to small intestinal bowel overgrowth (SIBO) is a contributing factor for flatus incontinence. The aims of our study were to assess the efficacy of metronidazole in a select population of patients with flatus incontinence associated with SIBO and to compare its efficacy with that of a combination of simethicone and activated charcoal (SC; Carbosyl...

A comprehensive theoretical/numerical model for treating AP/HTPB composite-propellant combustion in a rocket-motor environment is presented. The formulation takes into account the conservation equations in both the gas and condensed phases, and accommodates finiterate chemical kinetics and variable thermophysical properties. The processes in the two phases are coupled at the surface to determin...
