Abstract In this work, heat transfer, wall-to-bed, characteristics from elliptic tubes exchangers, both inline and staggered arrangements, were studied experimentally. Bundles of twenty the same total surface area 0.015 m 2 a length 200 mm are immersed in bed granulated charcoal different grain sizes, 2, 4 6 mm. Air was used as fluidizing fluid. One these which made copper, instrumented, electr...

The production technology of high-quality vodka used in Russia involves filtration through activated charcoal. To approach the quality of renowned Russian vodka, one prominent Czech spirit-producing company inst...

The experimental materials comprised 800 Cobb 500 broiler chickens. One-day-old chickens of both sexes were randomly allocated to two feeding groups, each with four replicates of 100 birds. The chickens were reared for six weeks on deep litter and were fed standard pelleted diets in a three-stage system (starter, grower and finisher). Control group (I) birds received basal diets and experimenta...

A new type of activated charcoal for the direct hemoperfusion (DHP) has been developed for use in treatment of fulminant hepatic failure. Bead-type activated charcoal from petroleum pitch (BAC) was coated with polyetherurethane. The coating has permitted the charcoal to minimize the number of released microparticles and yet to show nearly the same adsorption performance as that of the non-coate...

A new kind of low-cost syntactic adsorbent from bamboo charcoal and chitosan was developed for the removal of microcystin-LR from drinking water. Removal efficiency was higher for the syntactic adsorbent when the amount of bamboo charcoal was increased. The optimum dose ratio of bamboo charcoal to chitosan was 6:4, and the optimum amount was 15 mg/L; equilibrium time was 6 hr. The adsorption is...

BACKGROUND Tasks involved in traditional charcoal production expose workers to various levels of charcoal dust and wood smoke. This study aimed to identify specific tasks influencing lung function and respiratory symptoms. METHODS Interviews, direct observation, and task/symptom checklists were used to collect data from 50 charcoal-production workers on 3 nonwork days followed by 11 workdays....

Introduction: The determination of accurate dose distribution is an issue of fundamental importance in radiotherapy, especially with regard to the fact that the human body is a heterogeneous medium. Therefore, the present study aimed to analyze the density and isodose depth profiles of 6 MV beam in a SP34 slab-wooden dust (pine)-SP34 slab (SWS) heterogeneous phantom.  Materials and Methods: Th...

Lateral resistance of railway track is one of the most important parameters in lateral stability. This parameter depends!on the conditions of different components of ballasted railway track (such as density of ballast layer, sleeper spacing, type of sleeper, etc.). From this perspective, type of sleeper has an important effect on lateral resistance. However in some conditions, in technical and ...

To the editor: We would like to share recent advancements regarding the utilization of activated charcoal filters to adsorb volatile anesthetic agents (VAAs). Although activated charcoal has been known for many years to adsorb VAAs,1-3 it has only recently become commercially available and endorsed by the Malignant Hyperthermia Association of the United States (MHAUS).4 MHAUS has put forth upda...
