BACKGROUND The increased tidal volume (V(T)) applied to the ventilated lung during one-lung ventilation (OLV) enhances cyclic alveolar recruitment and mechanical stress. It is unknown whether alveolar recruitment maneuvers (ARMs) and reduced V(T) may influence tidal recruitment and lung density. Therefore, the effects of ARM and OLV with different V(T) on pulmonary gas/tissue distribution are e...

many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. on sloping basins, however, few such studies have been performed so that the issue requires more investigation. a significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. this study was carried ...

Compost tea (CT) is an unheated on-farm infusion of compost used as a spray or soil drench to promote plant growth and control foliar and root diseases. Because food safety involves all aspects from farm to fork, CT should meet basic microbiological criteria for water quality. This report describes the effects of two CT production processes, aerated and nonaerated, on growth and survival of foo...

BACKGROUND In vivo high-resolution micro-computed tomography allows for longitudinal image-based measurements in animal models of lung disease. The combination of repetitive high resolution imaging with fully automated quantitative image analysis in mouse models of lung fibrosis lung benefits preclinical research. This study aimed to develop and validate such an automated micro-computed tomogra...

the karyotypic characteristics of   chub, squalius cephalus have been investigated by examining metaphase chromosomes spreads obtained from gill and kidney tissues. the fish used in the study were caught with fishing nets from dumlu stream, one of the main tributaries of the karasu river. the live fish were transported to the laboratory,  kept in a well aerated aquarium before analysis and then...

in korea, hypertension has become more prevalent with the westernization of korean diets and lack of exercise. this study aimed at investigating the associations between physical fitness variables and hypertension status in korean women.the subjects were 9,216 women aged >20 years who visited a public health promotion center for physical fitness tests. cardiovascular respiratory fitness was eva...

Air–water flows at hydraulic structures are commonly observed and called white waters. The free-surface aeration is characterised by some intense exchanges of air and water leading to complex air–water structures including some clustering. The number and properties of clusters may provide some measure of the level of particle-turbulence and particle–particle interactions in the high-velocity ai...
