Mixed radioactive and chemical wastes stored in tanks across the DOE complex generate hydrogen, ammonia, nitrous oxide, and nitrogen by a complex series of radiolytic and thermolytic reactions. Flammable conditions may result when these gases accumulate in the dome space of the waste tanks. A phenomenological model was developed that successfully predicts gas generation rates for many of Hanfor...

UNLABELLED A computer program that models anesthetic uptake and distribution has been in use in our department for 20 yr as a teaching tool. New anesthesia machines that electronically measure fresh gas flow rates and vaporizer settings allowed us to assess the performance of this model during clinical anesthesia. Gas flow, vaporizer settings, and end-tidal concentrations were collected from th...

Anesthesia is used in theraphosid spiders to facilitate medical procedures (e.g., physical examination, sample collection, surgery); however, most information on this subject is anecdotal. This study was conducted to systematically determine the anesthetic parameters of wild-caught, subadult goliath birdeater spiders (Theraphosa blondi) (n = 11) and Chilean rose spiders (Grammostola rosea) (n =...

The proper management of solid waste is the need of the time. The solid waste consists of various components, some of them are biodegradable where as other are non biodegradable. The waste from various biodegradable sources could be utilized as a feed material for the gas production. The objective of this study is food waste management through biogas production. Various parameters were studied ...

Postoperative vomiting (PV) after adenotonsillectomy in children is a common problem with an incidence as high as 40-80%. Only few studies in the recent literature compared the effect of different anesthetic techniques concerning PV in children. The aim of this study was to compare the incidence of PV in two groups of children who underwent two different general anesthesia techniques in order t...

AN electrochemical sensor has previously been reported to provide useful detection of carbon monoxide while exposed to one minimum alveolar concentration of volatile anesthetics. My independent laboratory study yields further evidence supporting the possible utility of electrochemical carbon monoxide sensor measurements in anesthetic gas mixtures. Several scientific investigations have elucidat...

The energy demand in India is increasing substantially and the energy supply is not in pace with demand. The recovery of energy from waste material is one of the best methods to tackle the energy crisis. The potential for recovery of energy from urban waste is high in Maharashtra followed by Uttar Pradesh, Tamil Nadu and West Bengal. In this paper, anaerobic digestion method is used to find the...

In this work, the influence of different operating conditions on the biogas production from mechanically-biologically treated (MBT) wastes is investigated. Specifically, different lab-scale anaerobic tests varying the water content (26-43% w/w up to 75% w/w), the temperature (from 20 to 25°C up to 55°C) and the amount of inoculum have been performed on waste samples collected from a full-scale ...

The disposal and treatment of wastes generated in the leather industry has been the focus of several studies around the world. They intend to meet environmental legislation and make the process environmentally and economically viable. The anaerobic digestion process, which occurs in steps that involve acid and methane forming bacteria, can be an alternative since it turns the waste into renewab...
