Solar Energy Collection Analysis Tool For Conceptual Aircraft Design, Grant Glazebrook Dec 2012

Solar Energy Collection Analysis Tool For Conceptual Aircraft Design, Grant Glazebrook

Aerospace Engineering

As battery energy storage and solar cell technology improve, solar aircraft are increasingly being considered for High Altitude Long Endurance missions. Although solar vehicles may theoretically remain on-station indefinitely using the sun as a power source, their design and feasibility is sensitive to mission planning details as specific as the time history of the vehicle’s deck orientation relative to the sun; the energy available for capture by the on-board solar array is governed by the solar incidence angle, and at certain orientations, the vehicle may cast shadows on itself and further reduce its energy capture capabilities. To quantify these losses, …

Four Events Of Host Switching In Aspidoderidae (Nematoda) Involve Convergent Lineages Of Mammals, F Agustin Jimenez-Ruiz, Scott L Gardner, Graciela Navone, Guillermo Ortí

Publications

The Great American Interchange resulted in the mixing of faunistic groups with different origins and evolutionary trajectories that underwent rapid diversification in North and South America. As a result, groups of animals of recent arrival converged into similar habits and formed ecological guilds with some of the endemics. We present a reconstruction of the evolutionary events in Aspidoderidae, a family of nematodes that infect mammals that are part of this interchange, i.e., dasypodids, opossums, and sigmodontine, geomyid, and hystricognath rodents. By treating hosts as discrete states of character and using parsimony and Bayesian inferences to optimize these traits into the …

Competition theory predicts that local communities should consist of species that are more dissimilar than expected by chance. We find a strikingly different pattern in a multicontinent data set (55 presence-absence matrices from 24 locations) on the composition of mixed-species bird flocks, which are important sub-units of local bird communities the world over. By using null models and randomization tests followed by meta-analysis, we find the association strengths of species in flocks to be strongly related to similarity in body size and foraging behavior and higher for congeneric compared with noncongeneric species pairs. Given the local spatial scales of our …

Bone-Specific Overexpression Of Npy Modulates Osteogenesis, I Matic, B G. Matthews, T Kizivat, J C. Igwe, D J. Adams, Ivo Kalajzic

UCHC Articles - Research

Objectives

Neuropeptide Y (NPY) is a peptide involved in the regulation of appetite and energy homeostasis. Genetic data indicates that NPY decreases bone formation via central and peripheral activities. NPY is produced by various cell types including osteocytes and osteoblasts and there is evidence suggesting that peripheral NPY is important for regulation of bone formation. We sought to investigate the role of bone-derived NPY in bone metabolism.

Methods

We generated a mouse where NPY was over-expressed specifically in mature osteoblasts and osteocytes (Col2.3NPY) and characterized the bone phenotype of these mice in vivo and in vitro.

Results

Trabecular and cortical …


Distinct Mechanisms Mediate Naïve And Memory Cd8 T-Cell Tolerance, Evan R. Jellison, Elizabeth G. Lingenheld, Li Zu, Lynn Puddington, Leo Lefrancois Dec 2012

Distinct Mechanisms Mediate Naïve And Memory Cd8 T-Cell Tolerance, Evan R. Jellison, Elizabeth G. Lingenheld, Li Zu, Lynn Puddington, Leo Lefrancois

UCHC Articles - Research

Peripheral tolerance to developmentally regulated antigens is necessary to sustain tissue homeostasis. We have now devised an inducible and reversible system that allows interrogation of T-cell tolerance induction in endogenous naïve and memory CD8 T cells. Our data show that peripheral CD8 T-cell tolerance can be preserved through two distinct mechanisms, antigen addiction leading to anergy for naïve T cells and ignorance for memory T cells. Induction of antigen in dendritic cells resulted in substantial expansion and maintenance of endogenous antigen-specific CD8 T cells. The self-reactive cells initially exhibited effector activity but eventually became unresponsive. Upon antigen removal, the antigen-specific …

African American Women In Informal Leadership In The African Methodist Episcopal Church, Tava Renee' Herring Dec 2012

African American Women In Informal Leadership In The African Methodist Episcopal Church, Tava Renee' Herring

Theses & Dissertations

The purpose of this qualitative study was to explore the phenomenon of Church Mothers as they perceived themselves as informal leaders in the African Methodist Episcopal Church. While it is generally acknowledged that there are gender and minority differences in leadership, there has been little exploration in how these differences affect the overall landscape of leadership and leadership theory in the African American community. Criteria for participant selection for the study were informed by Pielstick’s characteristics of informal leadership: shared vision, communication, relationships, community, guidance, and character. The study was conducted from the Womanist perspective as a way of understanding …

Behavioral Life-Cycle Models Under Alternative Demographic Regimes, Timothy F. Harris Dec 2012

Behavioral Life-Cycle Models Under Alternative Demographic Regimes, Timothy F. Harris

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Social security in the United States will encounter financial strains due to an aging population. The decreasing worker to retiree ratio will reduce retirement benefits relative to today’s benefits so long as the tax rate and eligibility age are not altered. Policy makers assume that they should make policies to maintain the current benefit levels.

In contrast to this assumption, this paper does not presume that policy makers should preserve current benefits. An analysis of the required tax rate to maintain lifetime utility across the current and future demographic regimes is undertaken rather than just a calculation of the tax …

A Truly Radical Idea In Social Studies Education: Teach The State Standards, Richard Gardiner Dec 2012

A Truly Radical Idea In Social Studies Education: Teach The State Standards, Richard Gardiner

Journal of Contemporary Research in Education

State social studies standards are reflective of the concepts of Bloom’s taxonomy, emphasizing the development of higher order thinking skills. Standardized social studies tests, on the other hand, are not reflective of Bloom’s taxonomy and almost exclusively test for memorization and identification. In other words, the standards target very different objectives than the standardized tests are designed to assess. If, then, the central objective is to achieve adequate or higher standardized test scores, we must admit that it is not “standards-based” education that is desired, but rather test-focused instruction.

The Festive City, Evelyn Lincoln, Emily J. Peters

Books

In early modern Europe (1500-1800), festivals enlivened civic spaces with a frequency, scale, and magnificence unrecognizable to us today. Festivals marked ritual moments, praised political agendas, and provided public entertainment. Europe’s papal court, sovereign powers, civic governments, and high aristocracy sponsored festivals for all sorts of occasions, staging joyous entry processions when foreign dignitaries entered a city, celebrating coronations, marriages, royal births, and funerals, and honoring saint’s days and Carnival season. Festivals shaped the public spaces of European cities. Buildings, plazas, stairways, and roadways were constructed specifically with festivals in mind. Likewise, festivals put the social structure of the city …
