Recent advances in submarine rescue systems have allowed a transfer under pressure of crew members being rescued from a disabled submarine. The choice of a safe decompression procedure for pressurised rescuees has been previously discussed, but no schedule has been validated when the internal submarine pressure is significantly increased i.e. exceeding 2.8 bar absolute pressure. This study test...

The aim of this study was to assess the results of 5-year experience with minimally invasive operation without medial incision and resection cartilages for correction of pectum excavatum. From 2000 we made in our Hospital minimally invasive technique for the correction of pectus excavatum. 75 patients were treated by minimally invasive technique. A convex steel bar is inserted under the sternum...

The bar-headed goose flies over the Himalayan mountains on its migratory route between South and Central Asia, reaching altitudes of up to 9,000 m. We compared control of breathing in this species with that of low-altitude waterfowl by exposing birds to step decreases in inspired O(2) under both poikilocapnic and isocapnic conditions. Bar-headed geese breathed substantially more than both greyl...

Carbonisation of potassium phthalimide (PPI) generates microporous carbons with exceptional gas uptake at 25 °C; 5.2 mmol per g CO 2 @ 1 bar, and methane storage 338 cm 3 (STP) −3 100 bar 100–5 working capacity 249 .

Based on a new hesitant fuzzy partial ordering proposed by Garmendia et al.~cite{GaCa:Pohfs}, in this paper a fuzzy disjunction ${D}$ on the set ${H}$ of finite and nonempty subsets of the unit interval and a t-conorm ${S}$ on the set $bar{{B}}$ of equivalence class on the set of finite bags of unit interval based on this partial ordering are introduced respectively. Then, hesitant fuzzy negati...

A sinusoidal grating can be viewed as a series of light and dark bars. Here we measure the contrast discrimination thresholds for light and dark bars individually, and find that the contrast discrimination thresholds for the whole sinusoid can be explained as ideal summation of the light and dark bar thresholds. We propose a model for light bar, dark bar, and sinusoidal contrast discrimination ...

chamomile (matricaria recutita) is a highly valuable medicinal and aromatic plant of asteraceae family and its anthodia used frequently in pharmaceutical and cosmetic industries. the aim of this study was the evaluation the effect of drought stress induced by polyethylene glycol 6000 (peg) on germination percentage, germination rate, plumule and radicle length of four improved cultivars of germ...

The processing of cheese whey pre-concentrated by reverse osmosis is carried out through ultrafiltration in diafiltration mode to produce whey protein concentrates with lower lactose content to be incorporated in beverages. The initial cheese whey protein and lactose contents are 2.13g/100g and 13.22g/100g, respectively.The commercial membranes, GR95PP, supplied by Alfa Laval, Denmark, we...
