On The Relationship Between Pollen Size And Genome Size, Charles A. Knight, Rachel B. Clancy, Lars Götzenberger, Leighton Dann, Jeremy M. Beaulieu

Biological Sciences

Here we test whether genome size is a predictor of pollen size. If it were, inferences of ancient genome size would be possible using the abundant paleo-palynolgical record. We performed regression analyses across 464 species of pollen width and genome size. We found a significant positive trend. However, regression analysis using phylogentically independent contrasts did not support the correlated evolution of these traits. Instead, a large split between angiosperms and gymnosperms for both pollen width and genome size was revealed. Sister taxa were not more likely to show a positive contrast when compared to deeper nodes. However, significantly more congeneric …

“Little Language” Project Modules, John Clements, Kathi Fisler

Computer Science and Software Engineering

Many computer science departments are debating the role of programming languages in the curriculum. These discussions often question the relevance and appeal of programming-languages content for today's students. In our experience, domain-specific, “little languages” projects provide a compelling illustration of the importance of programming-language concepts. This paper describes projects that prototype mainstream applications such as PowerPoint, TurboTax, and animation scripting. We have used these exercises as modules in non-programming languages courses, including courses for first year students. Such modules both encourage students to study linguistic topics in more depth and provide linguistic perspective to students who might not otherwise be …

Impaired Vascular Reactivity Following Chronic Ischemia In The Arteries Of The Mouse Hindlimb, Thomas (Tom) Kesler

Biomedical Engineering

Collateral dependent hyperemia is reduced following chronic ischemia, but the contribution of individual vessel reactivity is unknown. Further, it is not known what aspect of the complex ischemic injury response impacts vascular reactivity. To determine the impact of ischemia on vascular reactivity, we measured functional vasodilation in the muscular branch artery following resection of the femoral artery proximal to the muscular branch. On day-14 after surgery the diameter of the muscular branch was measured using side-stream dark field (SDF) imaging intravital microscopy. At moderate intensity skeletal muscle contraction (1mA, 200µs, 8Hz, 90sec), functional vasodilation is reduced compared to the contralateral …

Bioluminescence In The Sea, Steven H.D. Haddock, Mark A. Moline, James F. Case

Biological Sciences

Bioluminescence spans all oceanic dimensions and has evolved many times—from bacteria to fish—to powerfully influence behavioral and ecosystem dynamics. New methods and technology have brought great advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities. Novel tools derived from understanding the chemistry of natural light-producing molecules have led to countless valuable applications, culminating recently in a related Nobel Prize. Marine organisms utilize bioluminescence for vital functions ranging from defense to reproduction. To understand these interactions and the distributions of luminous organisms, new instruments and platforms allow observations on individual to oceanographic …

The Metabolic Demands Of Swimming Behavior Influence The Evolution Of Skeletal Muscle Fiber Design In The Brachyuran Crab Family Portunidae, Kristin M. Hardy, Sean C. Lema, Stephen T. Kinsey

Biological Sciences

We investigated the influence of intracellular diffusion on muscle fiber design in several swimming and non-swimming brachyuran crabs. Species with sustained swimming behavior had aerobic dark fibers subdivided into small metabolic functional units, creating short diffusion distances necessary to support the high rates of aerobic ATP turnover associated with endurance activity. This dark fiber design was observed in all swimming species including Ovalipes ocellatus, which has apparently evolved swimming behavior independently of other Portunidae. In addition, we observed fiber and subdivision size-dependent differences in organelle distribution. Mitochondria, which rely on oxygen to function, were uniformly distributed in small fibers/subdivisions, …

Morphological Assessment Of Basic Multicellular Unit Resorption Parameters In Dogs Shows Additional Mechanisms Of Bisphosphonate Effects On Bone, Matthew R. Allen, Antonia M. Erickson, Xiang Wang, David B. Burr, R. Bruce Martin, Scott J. Hazelwood

Biomedical Engineering

Bisphosphonates (BPs) slow bone loss by reducing initiation of new basic multicellular units (BMUs). Whether or not BPs simply prevent osteoclasts from initiating new BMUs that resorb bone or also reduce the amount of bone they resorb at the BMU level is not clear. The goal of this study was to determine the effects of BPs on three morphological parameters of individual BMUs, resorption depth (Rs.De), area (Rs.Ar), and width (Rs.Wi). After 1 year of treatment with vehicle (VEH), alendronate (ALN; 0.10, 0.20, or 1.00 mg/kg/day), or risedronate (RIS; 0.05, 0.10, or 0.50 mg/kg/day), resorption cavity morphology was assessed in …

Physical Activity And Hormonal Regulation Of Appetite: Sex Differences And Weight Control, Todd A. Hagobian, Barry Braun

Kinesiology and Public Health

Physical activity is an important contributor to regulation of energy balance and body composition. In this article, we separate the impact of exercise from the confounding influence of energy imbalance and highlight sex differences in hormonal and appetite responses to physical activity. The evolving story may influence our thinking regarding the use of physical activity to manage body composition.

Andre eventually found ways to conquer his demons and eventually love himself and the support group around him. In this paper, I am going to explain the struggles Andre dealt with from childhood to the bad choices he made when he hit rock bottom. Then I am going to explain how he overcame these obstacles to become one of the greatest athletes to conquer his demons and eventually was able to educate thousands of young children and teach them …

Dual Polarization Interferometry For Small Molecules Drug Development, Sarwia Nawim, Brett Chromy, Lindsey Evans

STAR Program Research Presentations

Tularemia, also known as rabbit fever, is an infectious disease caused by the gram-negative bacterium Francisella tularensis. Transmission to animals and humans occurs via several routes, including ingestion of contaminated water, or inhalation of contaminated dusts or aerosols, tick bites, and skin contact with infected animals. Because of its highly pathogenic and opportunistic nature, F. tularensis is a likely candidate for use as an airborne biological weapon. For this reason, developing a vaccine and identifying appropriate treatments are critical to effective bioterrorism preparedness and response. It may exist in nature within encysted amoeba, which may represent a similar survival strategy …

Implementing Rfid To Improve Animal Shelter Inventory And Allocation, Adam Mach

Industrial and Manufacturing Engineering

The purpose of this project is to observe the best way to incorporate Radio Frequency Identification (RFID) technology into the animal inventory system present in animal shelters, while also observing the benefits of implementing this system. The Woods Humane Society was used in this project as a sample animal care facility that could benefit from this application.

Many RFID systems can be observed in other industries, but very few examples this technology exist in animal shelters or smaller animal care facilities. Part of the reason for that is because funds are scarce at most animal care facilities, like the Woods …

Reproductive Diseases Of Dairy Cattle, Christina Suzanne Tortosa

Dairy Science

The efficiency of today’s dairy has increased due to the growing number of cows per herd and the production of pounds of milk per cow. Increased milk production however has resulted in a reduction of conception rates causing a loss of income for the dairy producer since the dairy industry relies heavily on milk production, which is caused by good conception rates. Many reproductive disorders like dystocia, metritis, endometritis, and retained placenta affect conception rates, and can lead to metabolic diseases like rumen acidosis, milk fever, and displaced abomasums. Recurrent metabolic diseases can eventually lead to culling of the herd. …
