introduction: prolonged and intermittent oxygen pre-exposure is associated with protection against ischemic reperfusion (ir) injury. in the current study, attempts were made to investigate the relationship between exposure to prolonged and intermittent normobaric hyperoxia (nbho) and expression of excitatory amino acids transporters (eaats) and tnf-α level. method: rats were divided into four m...

intermittent drying is a satisfactory technique for drying of heat sensitive grains especially rough rice. this method consists of two separate stages applied intermittently: drying and tempering. in this work, intermittent drying of rough rice is investigated both theoretically and experimentally. in order to characterize this process; a multi-scale model consisting of macroscopic and microsco...

introduction according to the definition of world meteorology organization (wmo), as the speed of the air mass is more than 30 meters per second, the jetstream will arise. the core of the jetstream is with baroclinic atmosphere due to the large difference in temperature and wind speed. there are two west jetstreams in the northern hemisphere. the northern jet stream is called polar front jetstr...

A detailed investigation of the statistical properties near-field pressure fluctuations induced by an under-expanded jet, varying nozzle exit shapes has been presented. Experiments using different convergent Chevron nozzles were carried out in anechoic chamber at University Bristol to assess importance shape on near field emitted a single stream jet. Measurements through axial microphone array ...

Direct numerical simulations are performed to contrast turbulent boundary layers over a concave wall without and with free-stream turbulence. Adverse pressure gradient near the onset of curvature leads sharp decrease in skin friction intermittent separation. The presence turbulence reduces probability reverse flow, accelerates recovery layer downstream zero-pressure region, sustained appreciabl...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...
