BACKGROUND Sepsis could induce indirect acute lung injury(ALI), and pulmonary vasomotor dysfunction. While low tidal volume is advocated for treatment of ALI patients. However, there is no evidence for low tidal volume that it could mitigate pulmonary vasomotor dysfunction in indirect ALI. Our study is to evaluate whether low tidal volume ventilation could protect the pulmonary vascular functio...
Tidal cracks are linear features that appear parallel to coastlines in fast ice regions due to the actions of periodic and non-periodic sea level oscillations. They can influence energy and heat exchange between the ocean, ice, and atmosphere, as well as human activities. In this paper, the LINE module of Geomatics 2015 software was used to automatically extract tidal cracks in fast ice regions...
We report the detection of ongoing star formation in the prominent tidal arms near NGC3077 (member of the M81 triplet). In total, 36 faint compact H II regions were identified, covering an area of ∼ 4× 6 kpc. Most of the H II regions are found at H I column densities above 1 × 10 cm (on scales of 200 pc), well within the range of threshold columns measured in normal galaxies. The H II luminosit...
Six reservoirs in North Carolina, USA, discharge into the Pee Dee River, which flows 260 kilometers through South Carolina to the coastal communities near Myrtle Beach. During the Southeast’s record-breaking drought from 1998 to 2002, salinity intrusions inundated a coastal municipal freshwater intake, limiting water supplies. The North Carolina reservoirs are currently (2006) undergoing a re-l...
Australia's tidal marshes have suffered significant losses but their recently recognised importance in CO2 sequestration is creating opportunities for their protection and restoration. We compiled all available data on soil organic carbon (OC) storage in Australia's tidal marshes (323 cores). OC stocks in the surface 1 m averaged 165.41 (SE 6.96) Mg OC ha-1 (range 14-963 Mg OC ha-1). The mean O...
General circulation of Persian Gulf has a cyclonic pattern that affected by tide, wind stress and thermohaline force. Although tidal force is very effective in values of current speed, but thermohaline force is dominant in long time because tidal forcing has a short period and returning nature. Tide and density parameters are important in navigating and shipping, especially when ships approachi...
The results of a wide-field survey of the Sculptor dwarf spheroidal galaxy are presented. Our aims were to obtain an accurate map of the outer structure of Sculptor, and to determine the level of interaction between this system and the Galaxy. Photom-etry was obtained in two colours down to the magnitude limits of V = 20 and I = 19, covering a 3.1 × 3.1 deg 2 area centred on Sculptor. The resul...
Full tidal action was restored to a 28-ha marshland in the brackish region of the San Francisco Bay Estuary to evaluate the impact of increased tidal circulation on Aedes dorsalis abundance. One year after project completion, mosquito abundance had decreased by 98.7%, from an average of 3.6 to 0.3 4th-instar larvae per dip. Larvicide applications have consequently been reduced from approximatel...
