Ecosystem changes caused by anthropogenic activities have modified the environment in ways that at times promote the emergence of vector-borne diseases. Here, we study the effects of combined sewage overflows (CSOs) from urban streams in Atlanta, GA, on oviposition site selection by Culex quinquefasciatus under seminatural field conditions. Counting egg rafts was a reliable indicator of oviposi...

Cyanide (CN) is a toxic species that is found predominantly in industrial effluents generated by metallurgical operations. Cyanide's strong affinity for metals makes it favorable as an agent for metal finishing and treatment and as a lixivant for metal leaching, particularly gold. These technologies are environmentally sound but require safeguards to prevent accidental spills from contaminating...

A number of mosquito species avoid predator-inhabited oviposition sites by detecting predator-released kairomones. In the laboratory, we found that when offered de-ionized water and de-ionized water conditioned with Notonecta maculata, gravid Anopheles gambiae females preferentially oviposited into the former. We then conducted further experiments using two chemical components found in Notonect...

A novel method for the production of adenoviral vectors on a scale sufficient to support most research applications and early phase clinical trials is presented. This method utilizes serum-free cell culture medium and a hollow fiber cell culture apparatus. Significantly less time and space are required than in conventional methods, and the resulting adenovirus is collected in a much smaller vol...

First Question: Dredging of channels to keep them open to shipping is a recurring and costly activity, especially in cases where channels have to be deepened and maintained to accommodate larger and deeper-draft vessels. There is also the concern of how to dispose of the dredge spoil. How does the Corps balance the cost of dredging and dredge spoil disposal with NEPA requirements and with the e...

The demand for comfort cooling is increasing very quickly around the world, e.g. due to improved living standards. At present, air-conditioning is consuming large amounts of electricity, often during hours of peak power demand. Also, a major part of the electricity around the world is produced from fossil fuels, and thus the threat of global warming, caused by increasing emissions of carbon dio...

Agriculture, with its allied sectors, is unquestionably the largest livelihood provider in India, more so vast rural areas. It also contributes a significant figure to Gross Domestic Product (GDP). Sustainable agriculture, terms of food security, employment, and environmentally sustainable technologies such as soil conservation, natural resource management biodiversity protection, are essential...
