Water Quality Trends across Select 319 Monitoring Sites in Northwest Arkansas

Northwest Arkansas contains two 319 priority watersheds that the Arkansas Natural Resources Commission has identified as being impacted by point source and nonpoint source pollution (i.e., phosphorus, nitrogen, and sediment). This project specifically focused on determining water quality trends at select sites within the Illinois River (HUC# 11110103) and Beaver Reservoir (HUC# 11010001) priority watersheds, including Ballard Creek, Osage Creek, Illinois River, White River, West Fork White River and the Kings River where sufficient constituent data were available. Water quality trends were analyzed using flow‐adjusted constituent concentrations of phosphorus, nitrogen, sediment, sulfate and chloride, and parametric and non‐parametric statistical techniques to determine if constituent concentrations were increasing, decreasing or not significantly changing over time. Overall, flow‐adjusted concentrations of phosphorus and sediment have been decreasing across these watersheds based upon both statistical approaches. The decrease in phosphorus was likely the most important observation, because most water quality concerns in this region have focused on elevated phosphorus concentrations in these transboundary watersheds. These trends can be used along with other watershed information to improve the knowledge of how past, current, and future management decisions have influenced the watershed

Deflection resistance indicator

Instrument for nondestructively measuring compression resistance of spray foam used as thermal insulation was developed. Cylindrical indicator has probe with coil spring to provide force and indicating dial. Probe is manually pressed against area to be tested until complete foot area contacts foam surfaces

Missouri Beef Cattle Performance Testing Program

"2M/85""The Missouri Beef Cattle Performance Testing Program helps producers improve both quality and growth rate of their herds through breeding and selection. The primary objective of the Missouri Program is to provide education and information to both purebred and commercial producers so they can increase their economic returns. Area and state livestock specialists direct major efforts toward creating awareness of research technology, demonstrating the value of records of performance and adopting improved selection procedures. Missouri beef cattle improvement programs are designed to change the genetic base or gene frequency of economic traits of beef cattle in order to yield a more desirable product for the consumer. This in turn yields producers a higher return which helps improve their standard of living and provides capital with which to upgrade their operation."--from page 1Principal author: John W.

Using Hindsight to Change Child Support Obligations: A Survey of Retroactive Modification and Reimbursement of Child Support in North Carolina

The ratification of Chapter 50, section 13.10 of the North Carolina General Statutes, effective October 1, 1987, now focuses attention on the retroactive modifiability of court-ordered child support obligations in this state. Retroactive liability for child support, however, is not limited to retroactive changes in court-ordered support. The concept also includes retroactive changes in contractual child support obligations, as well as several miscellaneous remedies that allow a court to reimburse a parent, the state, or a third-party provider of necessaries for past expenditures on the child\u27s behalf

Selection of the herd bull

"Two major breeding programs in beef cattle improvement are: (1) purebred, in which the objective is to imrpove the genetic worth of the herd, and (2) commercial production, in which the objective is to take advantage of genetic material to achieve the greatest possible production. The two breeding programs are different. Selection for either system requires excellent judgment and timely decisions."--First page.John W.

Interview with W. T. Dub Massey

In his April 27th, 1981 interview with Phil O’Quinn, W.T. Massey recollects his involvement in the Civil Rights Movement as one of the Friendship 9 protestors and non-violent activists. Massey retells the preparation and events leading up to the sit-in at McCrory’s lunch counter. Massey also shares the negative effects he experienced with his involvement as an activist and leader in the Civil Rights Movement, in particular, his arrest from the McCrory’s sit-in. Massey concludes his interview with advice and hope for the black community. This interview was conducted for inclusion into the Louise Pettus Archives and Special Collections Oral History Program.https://digitalcommons.winthrop.edu/oralhistoryprogram/1154/thumbnail.jp

Graded infinite order jet manifolds

The relevant material on differential calculus on graded infinite order jet manifolds and its cohomology is summarized. This mathematics provides the adequate formulation of Lagrangian theories of even and odd variables on smooth manifolds in terms of the Grassmann-graded variational bicomplex.Comment: 30 page
