Sarcopenia And Aging: Skeletal Muscle Fiber Type Composition Of The Long-Lived Ames Dwarf Mouse Compared To Its Wild-Type Counterpart, Cory Leier

Physical Therapy Scholarly Projects

Skeletal muscle fiber type composition has not been studied in the long-lived Ames dwarf mouse when compared to its wild-type counterpart. Hindlimb soleus skeletal muscle from two 3-month old dwarf and two 3-month old wild-type mice was analyzed for muscle fiber size, proportion of type I (slow-twitch) and type II (fast-twitch) muscle fibers, myonuclei content per muscle fiber, and total cross sectional area of the muscle. Results revealed a significant difference in muscle fiber size (t(58)=-9.71, p

The Foster Parent Experience Of Attachment, Taylor Cohen

Master's Theses and Capstones

This study explores the attachment experience of foster parents. The researcher used a qualitative research framework to explore what 10 foster parents experienced in regards to attachment with their foster children. Based on the data and content analysis, a foster parent ecology emerged showing that the foster parent/child attachment relationship is affected by doctors, therapists, social workers, case workers, other foster parents, and the biological parents. The temporary nature of foster care and the goal of reunification of child to biological parent also affected the attachment relationship between foster parent and foster child.

The Effect Of Suspended Solids During Uv/Hydrogen Peroxide Advanced Oxidation Of Municipal Wastewater, Laith Furatian

Master's Theses and Capstones

As wastewater and water reuse practices evolve to meet changing effluent requirements, the capabilities of various technologies to achieve treatment objectives merit investigation. This work examines the influence of suspended solids on the efficiency of the UV-H2O2 advanced oxidation process to affect oxidation of organic contaminants in biologically wastewater effluents. Effluent samples from two conventional activated sludge plants were used to produce microfiltrates with 0.2 mum nylon filters. Para-chlorobenzoic acid (pCBA) was used as a probe compound to indirectly quantify the steady state OH concentration in samples spiked with H2O2 and irradiated using a bench-scale UV collimated beam apparatus. An …

High Energy Routes To Reactive Intermediates: Computational And Experimental Studies, Aida Ajaz

Master's Theses and Capstones

We developed microwave flash pyrolysis (MFP), using graphite and other sensitizers to carry out high temperature reactions. Newly developed is a closed vessel MFP method. Studies to date include isomerization of azulene to naphthalene, generation of benzyne, cycloaromatizations, and rearrangements. New thermal sensitizers included silicon carbide, titanium dioxide and diverse metal oxides. Graphite remains the most effective thermal sensitizer. Sealed tube MFP was utilized to investigate the Brown rearrangement of aryl alkynes. CCSD(T)//M05-2X computations have been carried out for both concerted and stepwise mechanisms in dehydro-Diels-Alder reactions of ethene and ethyne with vinylacetylene and 1,3-butadiyne. Concerted transition states for enyne-ene …

A sustainability assessment which combines the academic strengths of university research modeling with the practical inputs and needs of an operating utility is presented to compare two water treatment alternatives. PWN Water Supply Company is evaluating an upgrade from their current conventional coagulation and sand filtration (CSF) treatment process at WTP Andijk to Suspended Ion Exchange with Ceramic Microfiltration (SIX/CeraMac). An initial LCA was performed to determine which pretreatment is more sustainable in terms of energy consumption and carbon footprint.

The initial LCA indicated that treatment with SIX/CeraMac exhibits a lower impact as measured by kg of carbon dioxide equivalents …

Visual Arts And Literacy: The Potential Of Interdisciplinary Coalitions For Social Justice, Melanie L. Buffington, William Muth

Journal of Social Theory in Art Education

In this article, we explore the possibilities of creating a coalition of the visual arts with literacy to work toward meaningful integrated learning experiences with a social justice agenda. We discuss the benefits of integrated curriculum and its potential to support learning at many levels. Following that, we introduce the Hope House mural project as an example of an integrated visual arts and literacy program. Through this project, children and their incarcerated fathers grapple with significant issues in their lives and to build a bond while doing so. We argue that this coalition results in learning that is inseparably tied …

Adaptation Of Lambs To An Endophyte Infected Tall Fescue Seed Diet, Rachel Ann Rickly Zinner

Theses and Dissertations--Animal and Food Sciences

Ten wether lambs were used to determine the effects of ergovaline consumption from endophyte infected tall fescue, on nutrient utilization and metabolism. Lambs were fed a diet of 23% endophyte free tall fescue seed (E-) and 77% concentrate from d -14 to -1 (adaptation phase). On d 0, five lambs were switched to an endophyte infected seed diet (E+) where they remained through d 14. Nutrient digestibilities tended to increase from adaptation through the acute (d 1 to 4) to subacute (d 10 to 14) phases when E- was fed. E+ digestibilities were highest (P < 0.05) in the acute phase. Lambs fed E+ had higher rectal temperatures in the acute (P < 0.01) and subacute phases (P < 0.05). Fecal recovery of ergovaline increased as day of collection increased in the acute and subacute phases. Lysergic acid fecal recovery increased with day of collection in the acute phase, but no effect was found in the subacute phase. Serum enzyme analyses did not indicate tissue damage from alkaloid consumption. These results demonstrate lambs try to adapt to endophyte infected fescue seed consumption through increased nutrient digestibilities and increased ergovaline and lysergic acid excretion.

Role Of Helmet In The Mechanics Of Shock Wave Propagation Under Blast Loading Conditions, Shailesh G. Ganpule, Linxia Gu, Aaron L. Alai, Namas Chandra

Department of Mechanical and Materials Engineering: Faculty Publications

The effectiveness of helmets in extenuating the primary shock waves generated by the explosions of improvised explosive devices is not clearly understood. In this work, the role of helmet on the overpressurization and impulse experienced by the head were examined. The shock wave–head interactions were studied under three different cases: (i) unprotected head, (ii) head with helmet but with varying head–helmet gaps and (iii) head covered with helmet and tightly fitting foam pads. The intensification effect was discussed by examining the shock wave flow pattern and verified with experiments. A helmet with a better protection against shock wave is suggested.

Effects Of Mass Layer Nonuniformity On A Quartz-Crystal Microbalance, Nan Liu, Jiashi Yang, Weiqiu Chen

Department of Mechanical and Materials Engineering: Faculty Publications

We study the effects of the nonuniform thickness of a thin mass layer on a quartz-crystal microbalance. A theoretical analysis is performed on thickness-shear (TSh) vibration of an AT-cut quartz plate with a nonuniform mass layer. Mindlin’s 2-D equation for TSh vibration of a quartz plate is used. An elliptical mass layer with stepped thickness is considered which allows an exact analysis based on the plate equation. Free vibration frequencies and modes are obtained. The effects of the mass layer nonuniformity are examined. Results show that a mass layer thicker at the center tends to confine more modes under the …

What Anthropologists Should Know About The New Evolutionary Synthesis, Cameron M. Smith, Julia Cleverly Ruppell

Anthropology Faculty Publications and Presentations

Discoveries of modern biology are forcing a re-evaluation of even the central pillars of neo- Darwinian evolution. Anthropologists study the processes and results of biological and biocultural evolution, so they must be aware of the scope and nature of these changes in biology. We introduce these changes, comment briefly on how will influence anthropology, and suggest numerous readings to introduce anthropologists to the significance and substance of the new evolutionary synthesis.

Is Redd Accounting Myopic?: Why Reducing Emissions From Deforestation And Forest Degradation Programs Should Recognize And Include Other Ecosystems And Services Beyond Co 2 Sequestration, Paolo A. Lopes

PEEL Alumni Scholarship

This article argues that the current design of REDD is a myopic Partial PES at best. Forest ecosystems provide numerous services beyond the sequestration of CO2, such as protecting upstream watersheds, conserving biodiversity and gene pools, soil formation, nutrient recycling, and plant pollination. Thus REDD programs should recognize and include these and other ecosystem services. After reviewing REDD in the international context and the accounting scheme, recommendations and concerns are provided for why the expansion of REDD to include other ecosystems and services would result in not only a greater CO2 reduction, but also other important environmental benefits. The article …

Trace Element And Stable Isotopic Signatures In Otoliths And Pectoral Spines As Potential Indicators Of Catfish Environmental History, Kurt T. Smith, Gregory Whitledge

Publications

Natural chemical markers in otoliths and fin rays have proven useful for retrospectively describing environmental history of fishes in a variety of environments. However, no studies have applied this technique to catfishes or evaluated catfish pectoral spine chemistry as a nonlethal alternative to otolith chemistry. We characterized relationships between water, otolith, and pectoral spine (articulating process) chemistry for channel catfish Ictalurus punctatus, flathead catfish Pylodictis olivaris, and blue catfish I. furcatus and determined the accuracy with which fish could be classified to their environment of capture using otolith and pectoral spine chemical signatures. Fish and water samples were …

An Evaluation Of Hydrated Lime And Predator Sunfish As A Combined Chemical-Biological Approach For Controlling Snails In Aquaculture Ponds, Matthew R. Noatch, Gregory Whitledge

Publications

Aquatic snails are vectors for several species of digenetic trematodes which infest many commercially cultivated fish. Most research in methods of controlling snails in aquaculture ponds has centered on chemical solutions applied to pond margins and stocking of mollusk-eating fish. We sought to evaluate both methods separately and in tandem as a combination treatment for snails in research ponds under simulated commercial food fish production conditions. Hydrated lime (Ca[OH]₂) slurry applied at a rate of 31.7 kg/30.5 m of linear shoreline in a 1 m-wide swath produced a 99% reduction in estimated snail densities. However, estimated snail densities …

Contrasting Population Characteristics Of Yellow Bass (Morone Mississippiensis) In Two Southern Illinois Reservoirs, Kurt T. Smith, Neil P. Rude, Matthew R. Noatch, Dawn R. Sechler, Quinton E. Phelps, Gregory Whitledge

Publications

We investigated two southern Illinois reservoirs with contrasting size structures of yellow bass (Morone mississippiensis) to compare growth, mortality and recruitment patterns. Yellow bass were collected from Crab Orchard and Little Grassy Lakes during April-May 2009 using AC electrofishing. Total length and weight were recorded and sagittal otoliths sectioned and aged by two readers. Increments between otolith annuli were measured and the Weisberg linear growth model was used to assess age and environmental (growth year) effects on individual growth for fish from the two lakes. Von Bertalanffy growth models indicated faster growth and a greater maximum total length …

Otolith Trace Element And Stable Isotopic Compositions Differentiate Fishes From The Middle Mississippi River, Its Tributaries, And Floodplain Lakes, John M. Zeigler, Gregory Whitledge

Publications

Naturally occurring stable isotope and trace elemental markers in otoliths have emerged as powerful tools for determining natal origins and environmental history of fishes in a variety of marine and freshwater environments. However, few studies have examined the applicability of this technique in large river-floodplain ecosystems. This study evaluated otolith microchemistry and stable isotopic composition as tools for determining environmental history of fishes in the Middle Mississippi River, its tributaries, and floodplain lakes in Illinois and Missouri, U.S.A. Fishes were collected from 14 sites and water samples obtained from 16 sites during summer and fall 2006 and spring 2007. Otolith …

Cycles In Policy Network Structure And Policy Adoption-Implementation Processes: The Importance Of Alignment, Gwen Arnold

Working Papers

This paper investigates how aspects of policy networks facilitate or inhibit the efforts of public bureaucracies to adopt and implement science policy innovations. Three correlated dimensions of policy networks – permeability, size, and tie strength – strongly influence adoption and implementation outcomes. Policy networks tend to expand and contract cyclically along these network dimensions.

Policy adoption and implementation are not binary variables, but rather continually occurring processes that also cycle. Successful adoption and implementation outcomes are most likely when adoption-implementation and network expansion-contraction cycles are aligned such that adoption occurs when the policy network is more permeable, larger, and more …

International Civil Religion: Respecting Religious Diversity While Promoting International Cooperation, Amos Prosser Davis

UC Law SF International Law Review

International civil religion grounds moral claims that permeate and transcend traditional religious paradigms. Given the inevitability of international interactions - interactions that cross geographic, religious, and cultural boundaries - our global society is in need of a universally endorsable framework that undergirds the United Nations international human rights regime. International civil religion provides that framework.

Numerous scholars and moral theorists have incrementally discerned the parameters of civil religion including, inter alia, Jean-Jacques Rousseau, Alexis de Tocqueville, Robert Bellah, Martin Marty, and Harold Berman. The tenets of international civil religion infuse the diplomatically drafted United Nations covenants and conventions on human …

With Liberty And Justice For All [Families]: The Modern American Same-Sex Family, Lissette Gonzalez

St. Thomas Law Review

Evolutions in societal norms have redefined what it means to be a family in today's society. Due to the widespread shift in those who seek the aid of reproductive technologies, the number of would-be parents has greatly expanded. This great range of parenting possibilities presents novel and complicated issues in terms of legal parentage of children. In an attempt to address these novel issues, the Uniform Parentage Act was adopted in 2000, but has changed little since. Much inconsistency exists among and within the several states in determinations of legal parentage, largely in the area of same-sex couples. Adhering strictly …

In-Silico Prediction Of Disorder Content Using Hybrid Sequence Representation, Marcin J. Mizianty, Tuo Zhang, Bin Xue, Yaoqi Zhou, A. Keith Dunker, Vladimir N. Uversky, Lukasz Kurgan

Molecular Medicine Faculty Publications

Background: Intrinsically disordered proteins play important roles in various cellular activities and their prevalence was implicated in a number of human diseases. The knowledge of the content of the intrinsic disorder in proteins is useful for a variety of studies including estimation of the abundance of disorder in protein families, classes, and complete proteomes, and for the analysis of disorder-related protein functions. The above investigations currently utilize the disorder content derived from the per-residue disorder predictions. We show that these predictions may over-or under-predict the overall amount of disorder, which motivates development of novel tools for direct and accurate sequence-based …

Modulating Α-Synuclein Misfolding And Fibrillation In Vitro By Agrochemicals, Blanca A. Silva, Olöf Einarsdóttir, Anthony L. Fink, Vladimir N. Uversky

Molecular Medicine Faculty Publications

A combination of spectroscopic techniques including atomic force microscopy (AFM) and transmission electron microscopy (TEM), was used to analyze the effect of chemically distinct agrochemicals (pesticides, herbicides, and fungicides) on the in vitro misfolding and aggregation of a presynaptic intrinsically disordered protein α-synuclein. Despite their differences in chemical properties, almost all the compounds screened affected the α-synuclein fibrillation in a concentration-dependent manner. The morphology of the aggregated α-synuclein was characterized by AFM and TEM techniques. In addition to typical fibrils abundantly found at the equilibrium phase, this analysis revealed the existence of a noticeable nonfibrillar fraction where α-synuclein was present …
