Examples of sediment budgets are needed to document the range budget types and their controls. Sediment for three small agricultural catchments (7.6 15.6 km2) in southwestern Australia dominated by channel gully erosion, with sheet rill erosion playing a subordinate role. Erosion was increased clearing naturally swampy valley floors hillslopes agriculture grazing, episodic intense rainstorms. T...

comin the present study, co2 removal from natural gas stream has been studied using a flat sheet membrane contactor. a three dimensional mathematical model is developed to describe the process. the model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. the model is based on the non-wetted mode of operation, in which t...

The revised universal soil loss equation (RUSLE), the sediment delivery distributed (SEDD) model, and ArcView GIS were used to estimate the impacts of no-till practice on soil erosion and sediment yield in Pataha Creek Watershed, a typical dryland agricultural watershed in southeastern Washington. The results showed that the average cell soil loss decreased from 11.09 to 3.10 t/ha yr for the wh...

animal models for h.pylori infection have been developed to clarify the pathogenesis, testing new therapies and developing vaccines against human h.pylori infection. although rats have been used extensively for gastric ulceration and acid secretion studies, the animal is not normally infected with h.pylori.several chemicals such as ethanol and ammonium hydroxide can induce gastric erosion and i...

Correspondence Joint scintigraphy and erosions SIR, Isotope studies have been widely used in rheumatol-ogy for about 20 years. The study by Desaulniers and coworkers indicated that skeletal scintigraphy was a more sensitive method for the detection of inflammatory joint disease than radiography.' It appeared to be more sensitive than clinical evaluation in the diagnosis of joint inflammation of...
