In-Pond Raceways

In general, water cannot be economically pumped through raceways; it must flow through them by gravity. The need for large volumes of good quality water is the principal reason raceways have been limited to sites with large springs. Most raceway culture in the U.S. is with coldwater species such as trout and is based around locations with high volume, cold springs, or creeks. A few raceway syst...

Pond: The OceanStore Prototype

OceanStore is an Internet-scale, persistent data store designed for incremental scalability, secure sharing, and long-term durability. Pond is the OceanStore prototype; it contains many of the features of a complete system including location-independent routing, Byzantine update commitment, push-based update of cached copies through an overlay multicast network, and continuous archiving to eras...

The S.Tag fusion system for protein purification.

The detection, immobilization, and purification of proteins is idiosyncratic and can be problematic. Fortunately, these processes can be generalized by using recombinant DNA technology to produce fusion proteins in which target proteins are fused to carrier polypeptides. The affinity of the carrier for a specific ligand enables the facile detection, immobilization, and purification of a fusion ...

Algal Toxins in Pond Aquaculture

Algal toxins are organic molecules produced by a variety of algae in marine, brackish and fresh waters, as well as on wet soils (Falconer, 1993). They are a problem in aquaculture when they are produced in sufficient quantities, with sufficient potency, to kill cultured organisms, decrease feeding and growth rates, cause food safety issues, or adversely affect the quality of the product (Shumwa...
