Waste stabilization pond systems are widely used to treat animal wastes under highly variable hydraulic loading regimes. These systems have received limited research attention with regard to their hydrodynamic behaviour and the potential impact of shock hydraulic loading on their performance. In this study a two-stage dairy shed waste stabilisation pond system was topographically surveyed to de...

The heat extraction from the lower convective zone or storage zone of salinity gradient solar pond with corrugated bottom is investigated with the aim of increasing the overall efficiency of collecting solar radiation, storing heat and delivering this heat to different applications. The energy balance equations for each zone have been used to develop the expression of temperature distribution i...

To determine the feeding sites preferred by adult gold-spotted pond frogs, Rana plancyi chosenica, and the foods that induce favorable growth of the frogs in the laboratory, we conducted two separate experiments between 27 May and 12 July 2007 in a vivarium. In the first experiment, we counted the number of crickets eaten by four gold-spotted pond frogs in a 60 min period at four different feed...
