A Pebble - in - the - Pond Model For Instructional Design
Someone said, “It is a bad craftsman that blames his tools.” It should be obvious to the thoughtful observer that the problem may be the implementation of ISD, not a systematic approach itself. At the highest level of a systems approach one cannot imagine a design process that does not identify the training needs of an organization or the learning needs of the students. While learning occurs in...
متن کاملRaceway Pond Design for Microalgae culture for Biodiesel
Microalgae culture is a potential source of biodiesel and one of the best alternatives as raw material for biodiesel production. The first objective of this work is the pilot plant design for microalgae culture of high oil content species. The design was inspired by raceway large-scale culture. Although this kind of culture is usually in outdoor ponds, the pilot plant is an indoor raceway pond,...
متن کاملDesign and Application of a Solar Mobile Pond Aquaculture Water Quality-Regulation Machine Based in Bream Pond Aquaculture
Bream pond aquaculture plays a very important role in China's aquaculture industry and is the main source of aquatic products. To regulate and control pond water quality and sediment, a movable solar pond aquaculture water quality regulation machine (SMWM) was designed and used. This machine is solar-powered and moves on water, and its primary components are a solar power supply device, a sedim...
متن کاملAnalytical ultracentrifugation: sedimentation velocity and sedimentation equilibrium.
Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance, interference, and fluorescence) that permi...
متن کاملoptimum design of sedimentation basins in irrigation networks
abstract one of the problems in design of irrigation structures is sedimentation control in the inlet to the irrigation networks. water quality for agriculture requires that the sediments be controlled and reduced to the permissible limit at their entrance point to the turnouts and irrigation networks. this is possible by constructing a sedimentation basin. the bigger the basin, the best the re...
