Abstract: Recent studies have reported on the benefits of dynamic assessment (DA) in improving student learning and achievement through diagnostic monitoring of student misunderstandings, providing context-specific feedback, and ...

Abstract: A case study is presented to illustrate how an undergraduate hydraulic engineering course was refined to address student concerns, meet educational requirements and departmental goals, serve employer needs, and satisfy ...

Abstract: Biological treatment of airstreams has been shown to be useful when the airstreams are contaminated with low concentrations of volatile organic chemicals. One type of airphase biological reactor, the bioscrubber, has ...

Abstract: A simple modification of the conventional countercurrent air‐stripping process is proposed as “cascade air stripping” for cost‐effective removal of volatile organic contaminants from water. The feasibility of cascade air ...

Abstract: A simple modification of the conventional countercurrent air‐stripping process, introduced as cascade air stripping, is proposed for cost‐effective removal of semi‐ and low‐volatile organic contaminants from water. This ...

Abstract: Toxicity of eightand 10-component mixtures of several organic chemicals to activated sludge (A/S) microorganisms was analyzed. The joint toxic effects of the tested chemicals were found to be simply additive. The quantitative ...

Abstract: In this case study, we present a teaching approach that promotes active learning in engineering classes. Students are provided with a combination of physical, mathematical, and computer simulation models that allow them ...

Abstract: A broad weir-aeration model was derived to predict downstream dissolved oxygen (DO) over a wide range of upstream DO concentrations and fall heights. This model was then used to construct a three-dimensional (3D) surface ...

Abstract: Air-stripping is a viable treatment process for removing volatile organics from water. However, the design equations governing the stripping process do not often convey the sensitivity of the process to, and the critical ...
