Water balance in Narssaq river valley

Preceramic occupations in the orinoco river valley.

Two sites in the Orinoco Valley containing preceramic from excavated contexts are described. Radiocarbon dating and stylistic comparisons indicate that the northern tropical lowlands were inhabited at the onset of the Holocene, suggesting a time depth of 9000 years before the present for tropical forest-savanna adaptations in northern South America.

Association of arsenic-contaminated drinking-water with prevalence of skin cancer in Wisconsin's Fox River Valley.

During July 2000-January 2002, the Wisconsin Division of Public Health conducted a study in 19 rural townships. A high percentage of private drinking-water wells in these townships contained traces of arsenic. Residents were asked to collect well-water samples and complete a questionnaire regarding residential history, consumption of drinking-water, and family health. In total, 2,233 household ...

Seventh Annual Red River Valley Statistical Conference

Lyme Borreliosis, Po River Valley, Italy

We aimed to determine the presence of Ixodes ricinusticks in heavily populated areas of the Po River Valley after report of a Lyme disease case. Eighteen percent of ticks examined from 3 locations were positive for Lyme disease borreliae. Lyme disease was diagnosed for 3 workers at risk for tick bite.

Assessing Variation in Water Balance Components in Mountainous Inland River Basin Experiencing Climate Change

Quantification of the changes of water balance components is significant for water resource assessment and management. This paper employed the Soil and Water Assessment Tool (SWAT) model to estimate the water balance in a mountainous watershed in northwest China at different spatial scales over the past half century. The results showed that both Nash-Sutcliffe efficiency (NSE) and determination...
