West Nile virus monitoring among mosquito populations in Tarrant County, Texas has been ongoing for more than 4 years. Coupled with RT-PCR Testing by the North Texas Regional Laboratory, Tarrant County and the cities that ...
The Formation And Obduction Of Ophiolites Since The Late Precambrian
(Geology, 2007-08-23)
Ophiolite formation and emplacement has been episodic since the Late Precambrian. This research study examines ophiolites that formed during the Cenozoic, Mesozoic, Paleozoic and Late Precambrian. The ophiolites were ...
Selenium Speciation Along A Groundwater Flow Path In The Carrizo Aquifer, Southeastern Texas, USA
(Geology, 2007-08-23)
Selenium concentration and speciation [Se (VI), Se (IV) and Se (-II)] was determined along a flow path in the Carrizo Sand aquifer (southeastern Texas). Groundwater sampling was carried out in March 2006, from ten wells ...
