Previous studies have suggested that phenolics from legume green manures may contribute to weed control through allelopathy. The objective of this study was to determine how decomposition of red clover (Trifolium pratense L.) residue affects phytotoxicity to a weed species, wild mustard (Sinapis arvensis L.). Red clover (1.25 g), 30 g acid washed sand, and 5 ml of microbial inoculant were incub...

Climate change is a key topic of global concern, causing vigorous debate at local, national and international levels. The Carbon-Centric Computing Initiative (CCCI) was set up in 2008 by a cross-disciplinary group of researchers focused on the problem of climate change and using our capability as IT and related professionals to reduce our carbon footprint. A CCCI National Summit was held on Nov...

objective(s): this paper describes a selective and sensitive biosensor based on the dissolution and aggregation of aptamer wrapped single-walled carbon nanotubes. we report on the direct detection of aptamer–cocaine interactions, namely between a dna aptamer and cocaine molecules based on near-infrared absorption at λ807. materials and methods: first a dna aptamer recognizing cocaine was non-co...

In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of par...

Yousif K. Kharaka Nancy S. Dorsey

Kharaka has been a research hydrogeochemist with the U.S. Geological Survey since 1975. His investigations have emphasized waterrock interactions in petroliferous sedimentary basins. Current research covers the fields of water-rock-gas interactions, CO2 sequestration in saline aquifers, contamination from agricultural drainage and petroleum-produced water, and fluid-fault interactions. Kharaka ...
