Does Shape Predict Performance? An Analysis Of Morphology And Swimming Performance In Great Basin Fishes, John R. Aedo

Theses and Dissertations

Swimming performance strongly influences fitness in aquatic organisms and is closely tied to external body morphology. Although this connection has been closely examined at the individual and species level, few studies have focused on this relationship as it pertains to functional group assemblages. Using functional groups based on similarities in habitat use and morphology, I tested the hypothesis that swimming performance can be reliably predicted by functional group composition. I measured swimming performance as burst speed using a simulated predator attack and as prolonged speed using a step-endurance test in a laboratory flume. I measured morphology using geometric morphometric techniques. …

Fixing Foster Care: How Can We Best Support Foster Parents?, Erica S. Pistorino

Pell Scholars and Senior Theses

The foster care system aims to provide a temporary home to children who are unable to be cared for by their parents. The reasons for this vary, but can be due to ”abuse, neglect, or abandonment” (Marzick 507). According to the Pew Commission on Children in Foster Care, there are more than half a million children in our country who are currently in foster care. These children remain in the system for at least two years and are often moved around from family to family (Krinsky, “A Case” 541-542). This paper involves examining the foster care system, as well as …

A Review Of Lorraine Daston And Peter Galison’S Objectivity, Tom Strong

The Qualitative Report

Lorraine Daston’s and Peter Galison’s Objectivity (2007) traces historical and cultural developments as the word "objective" acquired different meanings and associated scientific practices. Similarly, Daston and Galison consider the changing relationship of the word "objective" as it relates to the subjectivity of the researcher. Objectivity will interest any reader interested in how the conceptions and practices of science change historically and culturally.

Scan-Rescan And Intra-Observer Variability Of Magnetic Resonance Imaging Of Carotid Atherosclerosis At 1.5 T And 3.0 T, Arvin Vidal, Yves Bureau, Trevor Wade, J David Spence, Brian K Rutt, Aaron Fenster, Grace Parraga

Medical Biophysics Publications

Carotid atherosclerosis measurements for eight subjects at baseline and 14 +/- 2 days later were examined using 1.5 T and 3.0 T magnetic resonance imaging (MRI). A single observer blinded to field strength, subject and timepoint manually segmented carotid artery wall and lumen boundaries in randomized images in five measurement trials. Mean increases in the signal-to-noise ratios (SNR) for T1-weighted images acquired at 3.0 T compared to 1.5 T were 90% (scan) and 80% (rescan). Despite significantly improved SNR and contrast-to-noise ratios (CNR) for images acquired at 3.0 T, vessel wall volume (VWV) intra-observer variability was not significantly different using …

Singularities Of Hinge Structures, Ciprian Borcea, Ileana Streinu

Computer Science: Faculty Publications

Motivated by the hinge structure present in protein chains and other molecular conformations, we study the singularities of certain maps associated to body-and-hinge and panel-and-hinge chains. These are sequentially articulated systems where two consecutive rigid pieces are connected by a hinge, that is, a codimension two axis. The singularities, or critical points, correspond to a dimensional drop in the linear span of the axes, regarded as points on a Grassmann variety in its Pl¨ucker embedding. These results are valid in arbitrary dimension. The three dimensional case is also relevant in robotics.

Extremal Configurations Of Hinge Structures, Ciprian Borcea, Ileana Streinu

Computer Science: Faculty Publications

We study body-and-hinge and panel-and-hinge chains in R^d , with two marked points: one on the first body, the other on the last. For a general chain, the squared distance between the marked points gives a Morse-Bott function on a torus configuration space. Maximal configurations, when the distance between the two marked points reaches a global maximum, have particularly simple geometrical characterizations. The three-dimensional case is relevant for applications to robotics and molecular structures.

The Use Of Wastewater And Inorganic Fertilizers As Nutrients Source For Cultivation Of Diatom Nitzschia Palea, Hussain A. Al-Saadi, Thaer I. Kassim, Jennan S. Al-Hassany

Obesity and nutrient homeostasis are linked by mechanisms that are not fully elucidated. Here we describe a secreted protein, adropin, encoded by a gene, Energy Homeostasis Associated (Enho), expressed in liver and brain. Liver Enho expression is regulated by nutrition: lean C57BL/6J mice fed high-fat diet (HFD) exhibited a rapid increase, while fasting reduced expression compared to controls. However, liver Enho expression declines with diet-induced obesity (DIO) associated with 3 months of HFD or with genetically induced obesity, suggesting an association with metabolic disorders in the obese state. In DIO mice, transgenic overexpression or systemic adropin treatment attenuated hepatosteatosis and …

Glypican-1 Modulates The Angiogenic And Metastatic Potential Of Human And Mouse Cancer Cells, Takuma Aikawa, Chery A. Whipple, Martha E. Lopez, Jason Gunn, Alison Young, Arthur D. Lander, Murray Korc

Dartmouth Scholarship

Cells isolated from many types of human cancers express heparin-binding growth factors (HBGFs) that drive tumor growth, metastasis, and angiogenesis. The heparan sulfate proteoglycan glypican-1 (GPC1) is a coreceptor for HBGFs. Here we show that both cancer cell–derived and host-derived GPC1 are crucial for efficient growth, metastasis, and angiogenesis of human and mouse cancer cells. Thus downregulation of GPC1 in the human pancreatic cancer cell line PANC-1, using antisense approaches, resulted in prolonged doubling times and decreased anchorage-independent growth in vitro as well as attenuated tumor growth, angiogenesis, and metastasis when these cells were transplanted into athymic mice. Moreover, athymic …

Supporting Lactation: Beyond Nutrition, Desiree' M. Bertilrud

Theses and Graduate Projects

Breastfeeding provides nutritional, health, immunological, psychological, economical and environmental benefits. Despite the abundance of scientific evidence and public health campaigns, the United States fails to meet national goals for breast feeding rates. Numerous barriers to lactation are identified and explored. However, by far, returning to work has the greatest impact on the duration of breastfeeding. Employers and organizations who support breastfeeding are the recipients of a multitude of benefits. The purpose of this project is to identify the strategic steps to establish a lactation room in an outpatient clinic setting for employees to support maternal-child relationships, foster employee satisfaction, and …

Synthesis And Evaluation Of Structural Analogs Of Escherichia Coli Lipid A For Application Towards Cd14-Targeting Glycotherapeutics, Aileen Fay Galos Bongat

Dissertations

Lipid A is a glucosamine-based phospholipid that anchors carbohydrate molecules to the outer membrane of most Gram-negative bacteria. During severe infection, this amphiphilic macromolecule invoke a strong and acute pro-inflammatory response that leads to sepsis and ultimately to septic shock, organ failure and death. Thus, following the convention that the best antidote is often a derivative of the parent agonistic molecule, researchers have actively pursued the idea of creating an analog of Lipid A that can block the cellular receptor for this molecule and thereby arrest the cascade of events that lead to sepsis. Consequently, we became interested in creating …
