Implementation Of Gy-Eq For Deterministic Effects Limitation In Shield Design, John W. Wilson, Myung-Hee Y. Kim, Giovanni De Angelis, Francis A. Cucinotta, Nobuaki Yoshizawa, Francis F. Badavi

Mathematics & Statistics Faculty Publications

The NCRP has recently defined RBE values and a new quantity (Gy-Eq) for use in estimation of deterministic effects in space shielding and operations. The NCRP's RBE for neutrons is left ambiguous and not fully defined. In the present report we will suggest a complete definition of neutron RBE consistent with the NCRP recommendations and evaluate attenuation properties of deterministic effects (Gy-Eq) in comparison with other dosimetric quantities.

Auger Timing Effects On Performance Of A Combine Unloading System, Todd Philip Cole

Open Access Master's Theses (through 2010)

Performance effects were measured on a combine unloading system using three different auger timing settings.Performance measures included maximum startup torque, mean operating torque, standard deviation of the operating torque, flow rate of grain through the system, and mechanical damage to the grain.The performance effects were measured with the system unloading corn and soybeans.

The data were statistically analyzed to check for interactions between the grains and differences between the timings.Using an alpha value of 0.1 it was found that timing 1 for both grains had a 3% (<2.4 L/s) higher flow rate over timings 2 and 3.Timings 1 and 2 for both grains had higher maximum startup torque, about 10% (60 N·m) more torque required than timing 3.In soybeans, timings 2 and 3 also had the smallest standard deviation in operating torque, about 30% (20 N·m) less than timing 1.We were unable to detect any differences in mechanical damage to corn or soybeans as a result of unloading auger timing.These findings suggest that timing 3, with the cross augers lagging 90° behind the vertical unloading auger, may require less maximum startup torque and less variation in torque for the cross augers to effectively fill the loosely filled space left after the vertical auger lifts the grain without extra torque effects of having the augers push against each other as they do in timing 1.

Cold Acclimation Strategy Is Highly Variable Among The Sunfishes (Centrarchidae), Peter J. Lavrentyev, Deidra R. Tschantz, Elizabeth L. Crockett

Biology Faculty Research

We tested the hypothesis that the physiological strategy for acclimating to low body temperature is similar among closely related fish. Largemouth bass (Micropterus salmoides), green sunfish (Lepomis cyanellus), bluegill sunfish (Lepomis macrochirus), black crappie (Pomonix nigromaculatus), and white crappie (Pomonix annularis), all members of the family Centrarchidae, were acclimated to 5° and 25°C. Morphometric variables (total mass, total length, organ masses) and enzyme activities (hexokinase; lactate dehydrogenase; and cytochrome oxidase in heart, liver, and muscle) were measured in 5°C- and 25°C-acclimated fish at 5° and 25°C assay temperatures. Each species displayed a distinct physiological response to cold acclimation that differed …

Flashman’S Revenge: Central Asia After September 11, Eugene B. Rumer

Strategic Forums

This paper examines the shifting strategic landscape of Central Asia in the aftermath of the September 11, 2001 terrorist attacks and assesses how the United States’ emergence as the preeminent power affects regional politics, security dynamics, and relationships among key Central Asian states. It explores how historical legacies, geopolitical competition, and evolving U.S. policy priorities — particularly those related to counterterrorism and regional access — influence the balance of power in the five Central Asian republics. Drawing on historical context and policy analysis, the author analyzes whether the geopolitical influence of external actors, regional security cooperation, and domestic political considerations …

Mandatory Child Abuse Reporting: Behaviors, Attitudes And Beliefs Among Psychologists Regarding Current And Proposed Statutes, Angela Marie Cavett

Theses and Dissertations

Child abuse is a serious societal problem that has occurred throughout history. However, only recently has society begun to formally confront child maltreatment by requiring professionals, including psychologists, to identify children who are being abused or neglected, through formal, mandated reporting. Child abuse reports are general addressed by social workers from Social Service Departments. However, this system is not always effective. Despite the mandates to report, psychologists have chosen to not report some cases, especially cases of mild physical abuse.

Psychologists make decisions regarding whether or not to report. This study elaborates on and extends what is known about psychologists' …

Effects Of Acid Mine Drainage On Limnological Conditions And Fish Assemblages In The Cumberland Plateau Region Of The North Chickamauga Creek System, Tennessee, Jennifer Copeland Backer

Masters Theses and Doctoral Dissertations

Acid mine drainage (AMD) is the primary water pollution problem in Appalachian streams. The Cumberland Plateau (Southwestern Appalachians ecoregion) portion of North Chickamauga Creek (NCC), a fourth-order tributary to the Tennessee River (Tennessee), has been impacted by decades of AMD from active and abandoned coal mines. I assessed stream characteristics at 19 sites in the Cumberland Plateau region of the NCC system; these data were used to create a GIS database. Limnological conditions and fish assemblage attributes were compared between AMD-impacted and reference sites. Relationships were examined among water quality, habitat, and fish assemblage variables. Stream pH averaged lower at …

Effect Of Riparian Land Use On The Biotic Integrity Of Fish Assemblages In Black Creek, Chattanooga, Tennessee, Jerri Leigh Phillips

Masters Theses and Doctoral Dissertations

Black Creek is a third-order Ridge and Valley stream (Tennessee River drainage) in Chattanooga, Tennessee. Most ofBlack Creek's watershed is forested (ca. 71% in 1991 ). However, increasing urban development, particularly along the riparian landscapes, could impact the stream's ecological health. I assessed fish assemblages (biotic integrity), water quality, instream habitat, and riparian land-use features at eight sites in Black Creek, May-June 2000. Water quality conditions (temperature, dissolved oxygen, pH, conductivity) were favorable for stream fishes, but some level of habitat degradation (bank erosion, sedimentation, loss of riparian vegetation) was observed at all sites. Electrofishing samples yielded a total of29 …

Contrasting Patterns Of Divergence In Quantitative Traits And Neutral Dna Markers: Analysis Of Clinal Variation, Jay F. Storz

Jay F. Storz Publications

Clinal variation in quantitative traits is often attributed to the effects of spatially varying selection. However, identical patterns can be produced by the interplay between purely stochastic processes (i.e. drift in combination with spatially restricted gene flow). One means of distinguishing between adaptive and nonadaptive causes of geographical variation is to compare relative levels of between population divergence in quantitative traits and neutral DNA markers. Such comparisons can be used to test whether levels of trait divergence attributable to additive genetic effects (as measured by Q_ST) exceed null expectations based on the level of divergence at neutral marker …

Travel Epidemiology. Who Perspective, Hussein A. Gezairy

Saudi Medical Journal

International travel is undertaken by large, and ever increasing numbers of people for professional, social, recreational and humanitarian purposes, and this upward trend looks set to continue. Travelers are exposed to a variety of health risks of the unfamiliar environment of the visited area. The risk of exposure is determined by destination, duration of the visit, purpose of the visit, behavior of the traveler and underlying physical and biological status of the traveler. However, most risks can be minimized by suitable precautions taken before, during and after travel. Travelers can themselves, also, easily introduce any infectious agents they may harbor …

Description Of Paranoplocephala Etholeni N. Sp. (Cestoda: Anoplocephalidae) In The Meadow Vole Microtus Pennsylvanicus, With A Synopsis Of Paranoplocehala S. L. In Holarctic Rodents, Voitto Haukisalmi, H. Henttonen, J. Niemimaa, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Paranoplocephala etholeni n. sp, parasitizing the meadow vole Microtus pennsylvanicus in Alaska and Wisconsin, USA. is described Paranaplocephala etholeni is morphologically most closely related to the Nearctic Paranoplocephala ondatrae (Rausch, 1948). Available data suggest that P. etholeni is a host-specific, locally rare species that may have a wide but sporadic geographical distribution in North America. The finding of P. ondatrae-like cestodes in Microtus spp. suggests that this poorly known species may actually be a parasite of voles rather than muskrat (type host). A tabular synopsis of all the known species of Paranoplocephala s. I. in the Holarctic region with …

The Birds Of St. Matthew Island, Bering Sea, Kevin Winker, Daniel D. Gibson, Arthur L. Sowls, Brian E. Lawhead, Philip D. Martin, Eric P. Hoberg, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

St. Matthew Island (608 249 N, 1728 429 W) and its small nearby satellites, Hall Island and Pinnacle Rock, are isolated in the north-central Bering Sea. This infrequently visited location occupies a geographic position with a deep Bering Land Bridge history and is in an area of interdigitation of the Old World, New World, and Beringian avifaunas. It is known for its three Beringian endemics, a bird (McKay’s Bunting, Plectrophenax hyperboreus), a small mammal, and a plant. This level of endemism is striking for a high-latitude island. The only previous summary of the avifauna of St. Matthew Island (Hanna …

The synlophe in A. patriciapilittae is composed of 26 ridges in the cervical zone and is continuous to the caudal extremity in males and females. Males are characterized by a complex dorsal ray and narrow trifurcate spicules (351-356 mm long) lacking an ‘‘eyelet,’’ with dissimilar ventral …

Urinary Excretion Of Dithiocarbamates And Selfreported Cruciferous Vegetable Intake: Application Of The ‘Method Of Triads’ To A Foodspecific Biomarker, Jay H. Fowke, James R. Hébert, Jed W. Fahey

Faculty Publications

Objective: Greater intake of Cruciferous vegetables (e.g. broccoli) may prevent cancer at several sites. Urinary excretion of isothiocyanate conjugates (dithiocarbamates, DTC) provides a specific biomarker of Cruciferous vegetable consumption suitable for epidemiological investigations. However, no gold-standard referent is available for evaluating urinary DTC levels as an estimator of Cruciferous vegetable consumption. We compared urinary DTC levels to intake as measured by two selfreported dietary assessment techniques. Design: Cruciferous vegetable consumption was measured before and after a behavioural dietary intervention using multiple 24-hour recalls (24HR), a foodcounting questionnaire (VFQ) and urinary DTC excretion levels. Analysis included a structural equation approach (Method …
