The milliped genus Euryurus Koch, 1847 (Polydesmida: Euryuridae) west of the Mississippi River; occurrence of E. leachii (Gray, 1832) on Crowley’s Ridge, Arkansas

The milliped genus Euryurus Koch, 1847, and the species, E. leachii (Gray, 1832) (Polydesmida: Euryuridae), are recorded from three sites on the northern part of Crowley’s Ridge (Cross, Lee, and Poinsett counties), Arkansas, where the only prior familial records are of Auturus evides (Bollman, 1887). Coupled with the published locality of E. leachii in Phillips Co., at the southern extremity of the Ridge, the only known occurrences of both the genus and species in Arkansas and west of the Mississippi River are in this physiographic feature. The Arkansas population is geographically peripheral but anatomically intermediate between the two recognized subspecies, E. l. leachii and E. l. fraternus Hoffman, 1978, and we do not assign it to a race. Molecular investigations seem necessary to resolve relationships in the “E. leachii complex.

Rotational dynamics of a superhelix towed in a Stokes fluid

Motivated by the intriguing motility of spirochetes (helically-shaped bacteria that screw through viscous fluids due to the action of internal periplasmic flagella), we examine the fundamental fluid dynamics of superhelices translating and rotating in a Stokes fluid. A superhelical structure may be thought of as a helix whose axial centerline is not straight, but also a helix. We examine the particular case where these two superimposed helices have different handedness, and employ a combination of experimental, analytic, and computational methods to determine the rotational velocity of superhelical bodies being towed through a very viscous fluid. We find that the direction and rate of the rotation of the body is a result of competition between the two superimposed helices; for small axial helix amplitude, the body dynamics is controlled by the short-pitched helix, while there is a cross-over at larger amplitude to control by the axial helix. We find far better, and excellent, agreement of our experimental results with numerical computations based upon the method of Regularized Stokeslets than upon the predictions of classical resistive force theory

The Effect of Voluntary Service on Adolescent Attitudes Toward Learning

In a nationwide poll commissioned by the American Association of University Women the data indicated that all students\u27 enthusiasm for math and science is greatest in the elementary years, and drops precipitously as they get older. By high school, 52 percent of boys think they would enjoy being a scientist, but only 29 percent of girls think they would. Because of these trends we designed a study to provide information on motivating youth in science learning

Native American Weight Loss Movement: Pilot Test of a Culturally Tailored Weight Loss Program for American Indians

American Indians (AIs) have higher rates of obesity than other racial/ethnic groups, placing them at heightened risk for cardiovascular diseases, diabetes, and certain cancers. Culturally appropriate weight loss interventions may be the key to reducing risk. The most successful program used in AI communities has been the Diabetes Prevention Program (DPP), which limits enrollment to individuals with a clinical diagnosis of pre-diabetes. The purpose of this pilot project was to modify and culturally tailor a weight loss intervention to AI communities in Kansas to improve weight loss related behaviors among those who do not qualify for the DPP. The Native American Weight Loss Movement (NAWLM) was developed from 2012-2014 using an iterative process with 4 sequential modifications to the program. Group 1 received a slightly modified version of the DPP that was originally tailored to African Americans. Each group received an improved program based on modifications from the previous group. Our analysis shows 36.1% (95% CI: 25.7, 47.5) of all participants (n=72) lost weight; a majority (63.9%, 95% CI: 52.8-75.0) maintained weight, gained weight, or dropped out. Among individuals who completed the program (n=34), 76.5% lost weight (95% CI: 61.4, 91.5). These individuals lost an average of 2.98% body weight (95% CI: 1.58, 4.37), with 6 participants losing \u3e7% body weight. While most participants who completed the program lost weight, more research is needed to determine factors that discourage drop-out and promote behavioral changes. NAWLM shows promise as a weight loss program for AIs who do not qualify for the DPP

Patient-reported efficacy 6 months after a 4-week rehabilitation 1 intervention in individuals with chronic ankle instability

The objective of this research report is to track the patient-reported efficacy of a 4-week intervention [wobble board (WB) 4 or resistance tubing (RT)] in decreasing symptoms of Chronic Ankle Instability (CAI) at 6 5 months post-intervention (6PI) as compared to immediately post-intervention (IPI)

Identification and localization of a stable sulfenic acid in peroxide-treated tetrachlorohydroquinone dehalogenase using electrospray mass spectrometry

Background: Tetrachlorohydroquinone dehalogenase catalyzes the reductive dehalogenation of tetrachlorohydroquinone to trichlorohydroquinone and then to 2,6-dichlorohydroquinone. This enzyme undergoes oxidative damage during purification which causes it to form aberrant products. The damage is reversible by treatment with dithiothreitol. Possible types of oxidative damage include an inappropriate disulfide bond, a cysteine sulfenic acid, or a methionine sulfoxide.Results: Using electrospray liquid chromatography / mass spectrometry, we have demonstrated that oxidation of tetrachlorohydroquinone dehalogenase with H2O2 results in formation of a sulfenic acid at Cys13. Further oxidation to a sulfinic acid was also observed.Conclusions: Oxidation of Cys13 to a sulfenic acid prevents the normal reductive dehalogenation reaction from being completed. This finding is consistent with previous work which suggested that Cys13 acts as a nucleophile during the conversion of tetrachlorohydroquinone to trichlorohydroquinone. The technique described for identification and localization of the cysteine sulfenic acid should be applicable to a wide variety of biological systems

WordCruncher: A Digital Research and Teaching Assistant

For humanities research or teaching projects, we each pick tools from our digital toolboxes. If we have few tools, our projects may be limited or take longer. When we become familiar with other tools, we may get ideas for other projects and learn how to do projects faster and better. WordCruncher is a free digital toolkit with tools to help you search, study, analyze, download, create, and share eBooks or corpora. For example, you can add searchable notes, highlight text, do advanced searches, see search keywords in context, and find collocates or n-grams in WordCruncher books that may include formatted multilingual text, images, tags, hyperlinks, dictionaries, and lemma lists. Other apps and online resources may lack helpful tools, tags, markup, formatting, speed, or data. One linguist used online data to create a 700 million-word WordCruncher corpus. He said, “I couldn\u27t have done a lot of my research with what is out there.” For many years, our team has helped BYU faculty, research assistants, and students use WordCruncher tools to answer research questions and enhance student learning. We often help convert digital materials into a WordCruncher book or corpus designed to facilitate a project. This presentation will be a quick overview of several projects that illustrate how faculty and students have used WordCrunchertools and data
