Stratification and mixing of the water column is an important dynamic process in estuary, which plays a significant role estuarine circulation, mass transport energy exchange. Based on multi-station synchronous observation data from 26 February to 6 March 2011 during dry season North Channel Changjiang Estuary, Richardson number, Simpson number potential anomaly were calculated analyze tidal va...
Filtration theory does not include the potential influence of pore structure on colloid removal by straining. Conversely, previous research on straining has not considered the possible influence of chemical interactions. Experimental and theoretical studies were therefore undertaken to explore the coupling of physical and chemical mechanisms of colloid straining under unfavorable attachment con...
AIM Evaluation of the wide range of normal findings in asymptomatic women undergoing dynamic magnetic resonance (MR) defecography. METHODS MR defecography of 10 healthy female volunteers (median age: 31 years) without previous pregnancies or history of surgery were evaluated. The rectum was filled with 180 mL gadolinium ultrasound gel mixture. MR defecography was performed in the supine posit...
BACKGROUND Constipation severity is often defined by symptoms including feelings of complete evacuation, straining, stool frequency and consistency. These descriptors are mostly obtained in the absence of laxative use. For many constipated patients laxative usage is ubiquitous and long standing. Our aim was to determine the impact of laxative use upon the stereotypic constipation descriptors. ...
Much attention has been directed recently to ultra-grain refining of metallic materials, where the grain size is reduced to less than 1 mm. It is expected that submicrometer grained structure would result in high strength and toughness at ambient temperature [1] as well as high strain rate or low temperature superplasticity at elevated temperatures [2,3]. It has been reported recently that ultr...
