Colorado methane study not clear–cut

Predicting landslides in clearcut patches

Accelerated erosion in the form of landslides can be an undesirable consequence of clearcut logging on steep slopes. Forest managers need a method of predicting the risk of such erosion. Data collected after logging in a granitic area of northwestern California were used to develop a predictive equation. A linear discriminant function was developed that correctly classified almost 90% of the da...

Hydraulic fracturing not responsible for methane migration.

Although Osborn et al. (1) provided important geochemical measurements of dissolved methane in a portion of the Appalachian basin, their report does not fully appreciate the geologic history of this region and misrepresents potential risks of modern drilling and completion techniques used to develop shale-gas resources. The fear that hydraulic fracturing is responsible for methane migration fro...

Distribution and origin of groundwater methane in the Wattenberg oil and gas field of northern Colorado.

Public concerns over potential environmental contamination associated with oil and gas well drilling and fracturing in the Wattenberg field in northeast Colorado are increasing. One of the issues of concern is the migration of oil, gas, or produced water to a groundwater aquifer resulting in contamination of drinking water. Since methane is the major component of natural gas and it can be disso...

Colorado Not All Bugs are Bad : Clinical Experiences with Probiotics

13 Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. The biologic effects of individual probiotics vary and each should be rigorously evaluated in a controlled fashion to define potential clinical utility. The mechanisms of action vary from probiotic to probiotic. Many probiotics help balance the intestinal microflora. Some can ...
