Analysis of the uranium to organic carbon relationship in the organic-rich Ohio Shale of eastern Kentucky
Organic-rich shales have become increasingly important to unconventional petroleum reservoirs, and tools such as the gamma-ray have been used to locate them due to the radioactivity of elements such as uranium, potassium, and thorium present within shales. Complex sedimentary processes of organic-rich black shales are responsible for highly variable geochemical signals. Generally, there is a strong correlation between gamma-ray signature, as a result of radioactive uranium (U), and total organic carbon (TOC) in many Devonian black shales due to similar depositional processes of U and TOC. However, this strong correlation between U and TOC does not seem to be present within the Cleveland Shale interval based on gamma-ray data.In order to interpret ancient ocean conditions, trace metal uranium and molybdenum (Mo), and total organic carbon inventory of the Cleveland Shale and Lower Huron members of the Devonian Ohio Shale Group of eastern Kentucky were evaluated in order to determine the degree of basin restriction and paleoredox state of the Appalachian Basin at the time of deposition. The Ohio Shale Group provides a remarkable study area for this investigation along the basin margin of the Appalachian Basin, as trace metal U and Mo data give insight on the opening and closing of the basin throughout the Devonian Period. The Cleveland member of the Ohio Shale Group displays a weak to moderate correlation between TOC and trace metal U and Mo. In contrast, the two subdivisions that are defined in this study of the Lower Huron of the same stratigraphic group has a much stronger correlation between TOC and trace metal U and Mo. In fact, many sections throughout the lower and uppermost Cleveland Shale interval have greater organic carbon contents (up to 6.0 wt.%) than that of sections in the Lower Huron that have more radioactivity as a result of higher U contents. This discrepancy between U, Mo, and organic carbon accumulation along the basin margin setting is a result of trace metal availability in the water column, basin geometry, location within the basin, and a fluctuating sea level that impacted the degree of restriction and sill depth dividing the water masses surrounding the Appalachian Basin
Recommendation to Reduce Patients’ Blood Pressure and Cholesterol Medication Costs
The Community Preventive Services Task Force recommends reducing patient out-of-pocket costs (ROPC) for medications to control high blood pressure and high cholesterol when combined with additional interventions aimed at improving patient–provider interaction and patient knowledge, such as team-based care with medication counseling, and patient education
Estimating the Value of Local Ownership to a State’s Economy: The Case of Kansas Farmer Cooperatives
Farmer cooperatives positively contribute to the vitality of many rural communities. The objective of this research is to measure the total economic and local contribution of farmer cooperatives to the Kansas economy. This analysis utilizes a unique data set to create customized grain cooperative sectors within the IMPLAN economic modeling system. Results show that in 2017, Kansas farmer cooperative business activity contributed over 9,000 jobs, 1 billion in output. These contribution estimates decrease considerably if cash patronage is assumed to be spent as a corporate dividend, which highlights the value of local ownership

Publicized Sobriety Checkpoint Programs A Community Guide Systematic Review
Context: Publicized sobriety checkpoint programs deter alcohol-impaired driving by stopping drivers systematically to assess their alcohol impairment. Sobriety checkpoints were recommended in 2001 by the Community Preventive Services Task Force for reducing alcohol-impaired driving, based on strong evidence of effectiveness. Since the 2001 review, attention to alcohol-impaired driving as a U.S. public health problem has decreased. This systematic review was conducted to determine if available evidence supports the effectiveness of publicized sobriety checkpoint programs in reducing alcohol-impaired driving, given the current context. The economic costs and benefits of the intervention were also assessed. Evidence acquisition: This review focused on studies that evaluated the effects of publicized sobriety checkpoint programs on alcohol-involved crash fatalities. Using Community Guide methods, a systematic search was conducted for studies published between July 2000 and March 2012 that assessed the effectiveness of publicized sobriety checkpoint programs. Evidence synthesis: Fourteen evaluations of selective breath testing and one of random breath testing checkpoints met the inclusion criteria for the systematic review, conducted in 2012. Ten evaluations assessed the effects of publicized sobriety checkpoint programs on alcohol-involve
