The study evaluated the status of fish pond projects initiated in the 1980s on resource-poor farms in Guatemala and Panama. In both places, the host country and the United States Agency for International Development (USAID) provided financial assistance and Auburn University provided technical support to the respective governments. The study examined the impact of aquaculture technology, extens...

The negative energy balance of wastewater treatment could be reversed if anaerobic technologies were implemented for organic carbon oxidation and phototrophic technologies were utilized for nutrient recovery. To characterize the potential for energy positive wastewater treatment by anaerobic and phototrophic biotechnologies we performed a comprehensive literature review and analysis, focusing o...

The impact of mosquito control on nontarget organisms using Abate-4-E was investigated in terms of immediate mortality and residual activity. Three 10 year old, man-made ponds having similar community structures and population densities were studied. The residual activity, determined by bioassays with 4th instar Aedes communis, was significantly longer in a relatively cooler pond. Populations o...

1761. Figure 1. CSR FeO map of the central basalt pond in Apollo crater. The edges of the basalt pond were modeled as different units due to lateral mixing with the surrounding materials. The absolute FeO abundances from CSR may be overestimated by as much as 2 wt.% [15]. Figure 2. Map of modeled Th compositions used in the forward model. Region 1 = 0.9 ppm Th, Region 2 = 2.5 ppm Th, and Region...
