Ms M. a 13 years old class III student presented with one year history of petrol fumes inhalation dependence and six months history of kerosene inhalation dependence. She liked the smell of fumes getting pleasant feeling of well-being and increased confidence. She though fulfilled all the criteria of inherent dependence differed from typical cases described in published reports. Like male prepo...

BACKGROUND To investigate factors related to prevention of self-immolation in west of Iran. METHODS In a case-control study, 30 consecutive cases of deliberate self-inflicted burns admitted to the regional burn centre (Imam Khomeini hospital in Kermanshah province, Iran) were compared with controls selected from the community and matched by sex, age, district-county of residence, and rural vs...

The purpose of the Energetically Autonomous Tactical Robot (EATR) TM project is to develop and demonstrate an autonomous robotic platform able to perform longrange, long-endurance missions without the need for manual or conventional re-fueling, which would otherwise preclude the ability of the robot to perform such missions. The system obtains its energy by foraging – engaging in biologically-i...

the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...

One of the most important problems environmental sciences is to determine limits for sustainable functioning affected ecosystems. The effects volatile hydrocarbons (such as gasoline and kerosene) on plants in natural ecosystems have been poorly studied date. present work outlines data a field experiment kerosene forest bog communities Central Russia. In this paper, we model influence spillage g...

mercaptans are commonly present in petroleum products. their foul odor and highly corrosive nature make them the most undesirable sulfur compounds so they should be removed because of environmental issues. merox process is used for oxidation of mercaptans to disulfide using air in the presence of alkaline solution and merox catalyst. in this paper, due to lack of information about the kinetic o...

This work investigates the effect of production scales (laboratory, bench, and pilot) by pyrolysis Açaí (Euterpe oleracea Mart.) seeds at 450 °C 1.0 atmosphere, on yields reaction products acid value bio-oils. The experiments were carried out in batch mode using a laboratory scale reactor 143 mL, bench 1.5 L, pilot L (≈1:10:1000). bio-oil was obtained scale, fractionated distillation to produce...

The article shows examples of the use Aspen Hysys software for optimization AVT-3 and AT-2 crude oil distillation units at Atyrau Oil Refinery. was implemented Refinery first time.Calculations were carried out to optimize refinery with construction a model in Hysys. As result calculations, possibility improving efficiency individual parts revealed, pilot runs on confirm. During run unit, restri...

The high internal resistance (Rint) that develops across the sediment microbial fuel cells (SMFC) limits their power production (~4/10 mW m−2) can be recovered from an initial oil-contaminated (OCS). In anolyte, Rint is related to poor biodegradation activity, quality and quantity of contaminant content in anode material. While on catholyte, depends properties oxygen reduction reaction (ORR),...
