The mainly sources for indoor radon concentrations in all types of houses are the soil radon flux under the building (about 80%) and the radon exhalation from building materials (about20%). Our paper presents two methods for simultaneous measurement of this exhalation from soil and building materials: (1) -charcoal adsorption, respectively (2)-Lucas cell method. The both methods are applicable ...

common yew taxus baccata l. is an evergreen, slow growing   tree, indigenous of hyrcanian forests in iran. discovery of paclitaxel as an   anti tumor agent in the bark of taxus has increased importance of this   plant for treatment of breast and ovary cancer, especially 7000 women die annually   due to breast cancer in iran. regarding destructive method of paclitaxel   production and protection...

Phenobarbitone elimination rate after oral charcoal Activated charcoal is used in treating poisoning by drugs to prevent their absorption. If given early and in a high dose (50 g) it will inhibit the absorption of over 90 % of most drugs.1 2A high proportion of many drugs with a long half life are excreted into the gut and reabsorbed. We report on the effect of activated charcoal, given orally ...

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...

Low molecular sialoglycoconjugates were isolated by the charcoal adsorption method from the urines of patients with mucolipidosis (one patient with mucolipidosis type I variant and three patients with mucolipidosis type II). The sialoglycoconjugates were fractionated into two major fractions (SG-1 and SG-2) by Sephadex G-25 gel filtration, and a strikingly increased excretion of the SG-1 fracti...

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...

Insulin-like growth factor I (IGF-I) stimulates hematopoiesis. We examined whether bone marrow stromal cells synthesize IGF-I. Secretion of IGF-I immunoreactivity by cells from TC-1 murine bone marrow stromal cells was time-dependent and inhibited by cycloheximide. Gel filtration chromatography under denaturing conditions of TC-1 conditioned medium demonstrated two major peaks of apparent IGF-I...

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.
