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...

Toxicology from across the pond.

Despite extensive educational and preventive efforts, fatality from poisoning is a growing public health concern. While strategies to reduce fatal unintentional poisoning in children have been largely successful, growing numbers of deaths from suicidality and substance abuse present unique challenges to the public health system.

The Stability and Thermal Performance of a Small Solar pond

A small salt gradient solar pond with an average surface area of 1.8 m2 and depth of 0.8m has been tested. The depths of storage, gradient and surface zones are 0.3, 0.27 and 0.07m, respectively. The temperature of the storage zone for the summer days reaches its maximum of 65˚ C after about 8 days. Daily variation of the storage zone temperature was about 8˚C which is due to small volume of th...
