The present study focus on the biodegradation of trinitrotoluene (TNT) by Bacillus sp. YRE1 isolated from red effluent in free state and also cells immobilized on charcoal and polystyrene. TNT degradation was monitored weekly for 168 hours, at 262 nm. Immobilized Bacillus sp. YRE1 was checked for its ability to degrade TNT by exposing it to different temperatures. It was found that both charcoa...

BACKGROUND The charcoal burning suicide epidemics in both Hong Kong and Taiwan have been well documented. However, little is known about the situation in Japan. AIMS To examine the impact of charcoal burning suicide on the overall and other method-specific suicide rates between 1998 and 2007 in Japan. METHOD Using data obtained from the Vital Statistics of Japan, negative binomial regressio...

Agriculture in the humid tropics is mostly limited by low soil fertility and invasion of weeds. The nutrient retention capacity of most soils is low and applied mineral fertilizers are rapidly leached into subsoil. Small farmers can not afford continuous mineral fertilizer input to compensate for the losses. Hence the dominating agricultural praxis is shifting cultivation accompanied with slash...

Diazepam ingestion along with ethanol is encountered commonly in drug overdose cases. In the present study, the effect of pH and ethanol on the adsorption of diazepam in the simulated gastric fluid and the simulated intestinal fluid onto activated charcoal was determined in vitro. The adsorption behaviors of diazepam in both simulated gastric and intestinal pH onto activated charcoal were studi...

Wardle et al. (Brevia, 2 May 2008, p. 629) reported that fire-derived charcoal can promote loss of forest humus and belowground carbon (C). However, C loss from charcoal-humus mixtures can be explained not only by accelerated loss of humus but also by loss of charcoal. It is also unclear whether such loss is related to mineralization to carbon dioxide or to physical export.

Objective The aim of this study was to evaluate the usefulness of reconstructed computed tomography (CT) images using OsiriX software in detecting wooden and bamboo foreign bodies. Methods Four sizes of wet and dry wooden and bamboo foreign bodies were selected to be analyzed. Those in the air and in the head of edible swine were scanned with a multidetector row CT scanner. The images were ev...

DESCRIPTION A 39-year-old man presented with a 5-day history of increasing left eye swelling and erythema, after a palm tree branch struck his face.

The canopy of many central African forests is dominated by light-demanding tree species that do not regenerate well under themselves. The prevalence of these species might result from ancient slash-and-burn agricultural activities that created large openings, while a decline of these activities since the colonial period could explain their deficit of regeneration. To verify this hypothesis, we ...

OBJECTIVE To analyze the efficiency of labeling impalpable breast lesions with inert charcoal suspension; to evaluate the morphological alterations associated with its use and to determine whether the use of charcoal labeling hampers the diagnostic interpretation of the pathologist. METHODS Was evaluated a total of 135 cases of impalpable breast lesions previously labeled with charcoal suspen...

Charcoal production is often accompanied with gaseous and particulate emission into the atmosphere and occupationally exposed workers could be affected. This cross sectional comparative study was carried out to assess the levels of carbon monoxide (CO), carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter (PM2.5) generated during the phases of charcoal prod...
