introduction gastric emphysema or pneumatosis is a rare finding. early endoscopy and urgent laparotomy is advised in post trauma patients. case presentation a 29 year old man presented with blunt abdominal injury following a high-speed motorbike crash he complained of abdominal pain and abdomen was distended. ct abdomen revealed air in the gastric wall with disruption of gastric mucosa. he had ...

background and aims:nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. the purpose ...

backgrounds and aims: ammonia removal from air to prevent severe damage to the environment and living organisms is very important. biofiltration is an efficient, easy, cost-effective, and environmentally friendly process for degradation of ammonia from waste air. the aim of this study is to investigate the efficiency of biological filtration using a compost and scallop bed for ammonia removal. ...

We report on low-temperature (4–320 K) transport properties of TaxN thin films deposited on an amorphous SiO2 substrate. In this work, TaxN thin films were restricted to a narrow range of x: 0.72 x 0.83 yet show considerable and nonmonotonic variation of their transport properties with Ta concentration. This behaviour is consistent with a local minimum in the density of electronic states at the...

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...
