Iron Insufficiency Compromises Motor Neurons And Their Mitochondrial Function In Irp2-Null Mice, Suh Young Jeong, Daniel R. Crooks, Hayden Wilson-Ollivierre, Manik C. Ghosh, Rachid Sougrat, Jaekwon Lee, Sharon Cooperman, James B. Mitchell, Carole Beaumont, Tracey A. Rouault

Department of Biochemistry: Faculty Publications

Genetic ablation of Iron Regulatory Protein 2 (Irp2, Ireb2), which post-transcriptionally regulates iron metabolism genes, causes a gait disorder in mice that progresses to hind-limb paralysis. Here we have demonstrated that misregulation of iron metabolism from loss of Irp2 causes lower motor neuronal degeneration with significant spinal cord axonopathy. Mitochondria in the lumbar spinal cord showed significantly decreased Complex I and II activities, and abnormal morphology. Lower motor neurons appeared to be the most adversely affected neurons, and we show that functional iron starvation due to misregulation of iron import and storage proteins, including transferrin receptor 1 …

Bird Strikes And Aircraft Fuselage Color: A Correlational Study, Esteban Fernández-Juricic, Jimmy Gaffney, Bradley F. Blackwelll, Patrice Baumhardt

United States Department of Agriculture Wildlife Services: Staff Publications

Collisions between birds and aircraft (bird strikes) pose safety risks to the public, cost airports and airlines money, and result in liability issues. Recent research suggests that aircraft visibility could be enhanced to increase detection and avoidance by birds. We questioned whether aircraft color scheme might play a role in bird-strike frequency. We used public records of bird strikes along with information on flights that were gathered by federal agencies in the United States. We estimated the bird-strike rates and compared them among airline companies using different fuselage color schemes, while controlling for aircraft type. Using an avian vision modeling …

Wildlife Risk To Aviation: A Multi-Scale Issue Requires A Multi-Scale Solution, James A. Martin, Jerrold L. Belant, Travis L. Devault, Bradley F. Blackwelll, Loren W. Berger, Samuel K. Riffell, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Aircraft collisions with birds and other wildlife (wildlife strikes) pose increasing safety and financial concerns to the aviation industry worldwide. Recent events such as the ditching of US Airways Flight 1549 in the Hudson River have renewed public interest in risks to aircraft posed by wildlife (Marra et al. 2009). However, wildlife biologists and aviation personnel have been aware of these issues for decades (Solman 1973, Blokpoel 1976). Since the inception of the Federal Aviation Administration’s (FAA) National Wildlife Strike Database in 1990, 99,411 reported wildlife strikes to airplanes have resulted in at least $1.2 billion annually in losses (direct …

Tools For Managing Invasions: Acceptance Of Non-Toxic Baits By Juvenile Nile Monitor Lizards And Burmese Pythons Under Laboratory Conditions, Peter J. Savarie, Richard M. Engeman, Richard E. Mauldin, Tom Mathies, Kenneth L. Tope

United States Department of Agriculture Wildlife Services: Staff Publications

Nile monitor lizards (Varanus niloticus) and Burmese pythons (Python molurus bivittatus) are large, invasive, predatory reptiles, which are now well established in south Florida. Acetaminophen was recently shown to be lethal to both animals and therefore has potential for inclusion in an integrated pest management effort to control these species. However, acceptable bait matrices for both species are still needed to deliver the toxicant. We tested nine candidate bait matrices on juvenile Nile monitor lizards and Burmese pythons in the laboratory. Baits were tested fresh and also after aging at 30°C and 50% relative humidity for …

Using Dietary Analyses To Reduce The Risk Of Wildlife–Aircraft Collisions, Brian E. Washburn, Glen E. Bernhardt, Lisa A. Kutschbach-Brohl

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-Aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft and cost civil aviation >$614 million annually in the United States (Dale 2009, Dolbeer et al. 2009). Over 89,700 wildlife strikes with civil aircraft were reported to the U.S. Federal Aviation Administration (FAA) during 1990 to 2008 (Dolbeer et al. 2009). Aircraft collisions with birds accounted for 97% of the reported strikes (Dolbeer et al. 2009). Gulls (Larus spp.), waterfowl, such as Canada geese (Branta canadensis), raptors (hawks and owls), blackbirds, and European starlings (Sturnus vulgaris) are the species of most concern at airports …

Rodent Population Management At Kansas City International Airport, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Birds pose serious hazards at United States airports because of the potential for collisions with aircraft. Raptors, in particular, are hazardous to aircraft safety due to their size, hunting behavior, and hovering and soaring habits. Reduction of rodent populations at an airport may decrease raptor populations in the area and, therefore, reduce risk that raptors pose to aircraft. Rodent populations can be reduced by population management (i.e., use of rodenticides) or by habitat management (i.e., vegetation and land-use management) that reduces the area’s carrying capacity for rodents. I found that zinc phosphide-treated oats reduced rodent populations by >94% at the …

Generation Of Forests On Terrain With Dynamic Lighting And Shadowing, Jonathan Ben-David

Master's Projects

The purpose of this research project is to exhibit an efficient method of creating dynamic lighting and shadowing for the generation of forests on terrain. In this research project, I use textures which contain images of trees from a bird’s eye view in order to create a high scale forest. Furthermore, by manipulating the transparency and color of the textures according to the algorithmic calculations of light and shadow on terrain, I provide the functionality of dynamic lighting and shadowing. Finally, by analyzing the OpenGL pipeline, I design my code in order to allow efficient rendering of the forest.

Systemic Adiponectin Malfunction As A Risk Factor For Cardiovascular Disease., Wayne Bond Lau, Ling Tao, Yajing Wang, Rong Li, Xin L Ma

Department of Emergency Medicine Faculty Papers

Adiponectin (Ad) is an abundant protein hormone regulatory of numerous metabolic processes. The 30 kDa protein originates from adipose tissue, with full-length and globular domain circulatory forms. A collagenous domain within Ad leads to spontaneous self-assemblage into various oligomeric isoforms, including trimers, hexamers, and high-molecular-weight multimers. Two membrane-spanning receptors for Ad have been identified, with differing concentration distribution in various body tissues. The major intracellular pathway activated by Ad includes phosphorylation of AMP-activated protein kinase, which is responsible for many of Ad's metabolic regulatory, anti-inflammatory, vascular protective, and anti-ischemic properties. Additionally, several AMP-activated protein kinase-independent mechanisms responsible for Ad's anti-inflammatory …

Animal Welfare Update, J. David Aiken

Cornhusker Economics

Beginning in 2002, the Humane Society of the United States (HSUS) embarked upon a campaign to ban battery cages for laying hens, gestation crates for pregnant sows and veal crates for veal calves. The HSUS strategy is to gather sufficient signatures to place their animal welfare initiative on the ballot, and present an emotional campaign regarding food animal confinement including sad pictures of laying hens, pregnant sows and veal calves in tight confinement. This approach has resulted, in recent years, in voter support exceeding 60 percent.

It seemed that the HSUS could do no wrong, and that wherever they proposed …

Injuries to the anterior cruciate ligament (ACL) occur frequently, particularly in young adult athletes, and represent the majority of the lesions of knee ligaments. Recent investigations suggest that the assessment of kinematic variability using measures of nonlinear dynamics can provide with important insights with respect to physiological and pathological states. The purpose of the present article was to critically review and synthesize the literature addressing ACL deficiency and reconstruction from a nonlinear dynamics standpoint.

Methods

A literature search was carried out in the main medical databases for studies published between 1990 and 2010.

Results

Seven studies investigated knee kinematic …

From The W-Method To The Canonical-Dissipative Method For Studying Uni-Manual Rhythmic Behavior, Dobromir Dotov, Till D. Frank

Journal Articles

A novel method for the analysis of repetitive limb behavior oscillation is presented. It is based on a model used to account for self-sustained limit cycles that involve energy pumping compensating for dissipative processes. The experiment involved a uni-manual pendulum swinging task paced at five frequencies. The median frequency corresponded to the resonant one for the chosen pendulum and hand parameters. We applied the model-based analysis to explore the relationship between behavioral observables and model parameters not available from previous methods. Oscillation amplitude and energy, and motor variability were the behavioral observables we focused on while energy pumping, attractor strength, …

Post-9/11 Nihilism And The Mission For Meaning, Bill Durodie

Reconstruction: Studies in Contemporary Culture

[First paragraph]

At the height of the Mumbai siege in November 2008, one of the perpetrators, Fahad Ullah, used the mobile phone of one of the victims to call India TV and conducted a live interview with two journalists there. About a minute into their conversation, the two journalists, one male, one female, each asked in turn "What are your demands?". Ullah answered "Wait one minute" and was heard consulting with someone else as to what their demands were. The episode is one of the most revealing vignettes of the nature of contemporary terrorism.

Animal Enrichment Strategies For Promoting Natural Behaviors In Captive Populations Of Tasmanian Devils (Sarcophilus Harrisii), Tierney O’Neal

Independent Study Project (ISP) Collection

The population of Tasmanian devils (Sarcophilus harrisii) is in rapid decline due to Devil Facial Tumour Disease, and insurance populations have been created in captivity for potential future introduction into the wild. Many problems can arise within captive animal populations including loss of natural behaviors, and development of negative stereotypical (i.e. pacing) behaviors. These issues can decrease ecological fitness, potentially jeopardizing success of introductions of animals into the wild. By providing captive animals with enrichment, natural behaviors can be increased, and stereotypical behaviors can be decreased. Enrichment is defined as an activity or item that promotes the mental and physical …

Experimental Investigation And Cfd Simulation Of Active Damping Mechanism For Propellant Slosh In Spacecraft Launch Systems, Dhawal Leuva

Doctoral Dissertations and Master's Theses

Motion of propellant in the liquid propellant tanks due to inertial forces transferred from actions like stage separation and trajectory correction of the launch vehicle is known as propellant slosh. If unchecked, propellant slosh can reach resonance and lead to complete loss of the spacecraft stability, it can change the trajectory of the vehicle or increase consumption of propellant from the calculated requirements, thereby causing starvation of the latter stages of the vehicle. Predicting the magnitude of such slosh events is not trivial. Several passive mechanisms with limited operating range are currently used to mitigate the effects of slosh. An …

Bilateral Oscillatory Hip Movements Induce Windup Of Multijoint Lower Extremity Spastic Reflexes In Chronic Spinal Cord Injury, Tanya Onushko, Allison S. Hyngstrom, Brian D. Schmit

Physical Therapy Faculty Research and Publications

After spinal cord injury (SCI), alterations in intrinsic motoneuron properties have been shown to be partly responsible for spastic reflex behaviors in human SCI. In particular, a dysregulation of voltage-dependent depolarizing persistent inward currents (PICs) may permit sustained muscle contraction after the removal of a brief excitatory stimulus. Windup, in which the motor response increases with repeated activation, is an indicator of PICs. Although windup of homonymous stretch reflexes has been shown, multijoint muscle activity is often observed following imposed limb movements and may exhibit a similar windup phenomenon. The purpose of this study was to identify and quantify windup …
