By lumping together charcoal and firewood consumption to determine the threats to forests from widespread use of woodfuel energy in sub-Sahara African, studies have greatly underestimated the individual impact of charcoal. Where high consumption levels are coupled with poor forest management and negligible regulation of the charcoal trade, the threat of an impending crisis caused by charcoal al...

Neutralization represents an important goal in toxicology, reducing exposure to poison being crucial in any management plan of any intoxication. Controversial data actually exists in the literature regarding activated charcoal capacity to bind organophosphates. To determine and compare organophosphate binding capabilities for different hydrophobic substances, considered to have neutralising pro...

Industrial merbau wood sawn waste has not been utilized as an alternative fuel. The increase in fuel prices is a policy dilemma for the government and currently subsidies have abolished, because most of them only benefit upper class industry. problems faced by both rural urban communities are due to expensive unaffordable price fuel, delays supply which result scarcity long queues get Sawn prob...

This study experimentally analyzed the carbon dioxide adsorption capacity of Moso-bamboo- (Phyllostachys edulis-) based porous charcoal. The porous charcoal was prepared at various carbonization temperatures and ground into powders with 60, 100, and 170 meshes, respectively. In order to understand the adsorption characteristics of porous charcoal, its fundamental properties, namely, charcoal yi...

Monitoring methyl bromide (CH3Br) emission into the atmosphere following soil fumigations requires sensitive and reproducible sampling methods. The factors affecting the sampling efficiency and stability of CH3Br on activated charcoal sampling tubes were identified and evaluated in this study. The number of tubes required for accurate sampling using activated coconut and petroleum charcoal tube...

The use of Stainer-Scholte broth supplemented with (2,6-O-dimethyl)beta-cyclodextrin (heptakis) for the isolation of Bordetella pertussis from clinical specimens was evaluated with 3,632 nasal swabs from children and adults with suspected whooping cough or from their family contacts. The liquid enrichment medium was subcultured on charcoal agar with 10% defibrinated horse blood. Charcoal agar a...

PURPOSE A charcoal filter attached within the anesthetic circuit has been shown to efficiently adsorb halothane or isoflurane, thus hastening anesthetic recovery in low or minimal flow system. This study was intended to demonstrate whether the charcoal filter enhances the recovery time from sevoflurane anesthesia using a semi-closed circuit system. MATERIALS AND METHODS Thirty healthy patient...

It is a high efficiency，energy-saving and emission reduction measure to replace coal with biomass briquette fuel in layer combustion furnace, but the process, serious slagging problem has been restricted promotion of fuel. By analyzing characteristics briquette, ash fusion mechanism, combined important influence key parameters (furnace temperature, excess air, thickness) on furnace obtained, wh...

Over the past several decades, high-resolution sediment–charcoal records have been increasingly used to reconstruct local fire history. Data analysis methods usually involve a decomposition that detrends a charcoal series and then applies a threshold value to isolate individual peaks, which are interpreted as fire episodes. Despite the proliferation of these studies, methods have evolved largel...
