First Approaches To Standard Protocols And Reference Materials For The Assessment Of Potential Hazards Associated With Nanomaterialss, Gordon Chambers, Hugh Byrne, Iseult Lynch, Micheal Riediker, Hans Bouwmeester, Hans Marvin, Alan Casey, Markus Berges, Martin Clift, Teresa Fernandez, Lise Fjellsbo, Lucienne Juillerat, Gert Roebben, Christoph, Klein, Qinglan Wu, Vince Hackley, Jean-Pierre Kaiser, Wolfganag Kreyling, Michael Garner, Peter Hatto,, Kenneth Dawson

Articles

All new technologies have an inherent risk, which is typically assessed alongside the development of applications of the technology. This is also the case for nanotechnology: a key concern in the case of engineered nanomaterials (ENMs) is that due to their very small size, NMs can reach areas such as the cell that are inaccessible to other materials, such as implants and drugs. As a result of their large surface area, NMs may be more reactive than other larger materials. The large physical and chemical variability of NMs, and the fact that small changes can have large consequences, mean that …

Assessing The Potential Habitat Value Of Biomass Production Fields For Grassland Birds, Mandy Larson

Honors Program Theses

In this paper, I researched the habitat requirements of grassland birds in general, including an in-depth analysis of the specific habitat requirements of four selected species: Bobolink (Dolichonyx oryzivorus), Dickcissel (Spiza Americana), Grasshopper Sparrow (Ammodramus savannarum), and Sedge Wren (Cistothorus platensis). In the second part of my research, I evaluated three possible scenarios that could be used for biomass production in Iowa and reviewed the methods producers employ in establishing and managing their fields. I evaluated area, species diversity, timing of harvest, edge habitats, and fertilizers/chemicals used during production. Then I compared these three biomass production scenarios to the habitat …

Advertising Connoisseurs: Children's Active Engagement With And Enjoyment Of Television Advertising, Margaret-Anne Lawlor

Articles

The literature pertaining to advertising and children has tended to focus on how advertising affects children at cognitive, attitudinal and behavioural levels. A key element of the debate has been the extent to which children understand advertising as a mode of commercial communication, and the potential associated outcomes such as advertising scepticism and pester power. This paper adopts a different approach by exploring the extent to which television advertising can constitute a resource for a child's own use and enjoyment. As part of an interpretive study of a group of Irish children aged seven to nine years which explores their …

The following article analyzes the process of conception, elaboration, and adoption of the Universal Declaration of Bioethics and Human Rights, and reflects on the lessons it might hold for public bioethics on the international level. The author was involved in the process at a variety of levels: he provided advice to the IBC on behalf of the President's Council of Bioethics; he served as the U.S. representative to UNESCO's Intergovernmental Bioethics Committee; and led the U.S. Delegation in the multilateral negotiation of Government experts that culminated in the adoption of the declaration in its final form. The author is currently …

The Effectiveness Of Biodiversity Law, John Copeland Nagle

Journal Articles

The Endangered Species Act (ESA) has generated a heated debate between those who believe that the law has succeeded and those who believe that the law has failed. The resolution to that debate depends upon whether the law’s stated purposes or some other criteria provide the basis for judging a law’s effectiveness. Meanwhile, since the enactment of the ESA in 1973, biodiversity protection has received growing attention in the nations of southeastern Asia. So far, the law has been much less effective in protecting Asian biodiversity from habitat loss, commercial exploitation, and other threats, yet southeastern Asia’s biodiversity law has …

Land Trusts That Conserve Communities, James J. Kelly Jr.

Journal Articles

Much has been written about land trusts that conserve wilderness, agriculture or other environmentally beneficial uses that would be threatened by unfettered development. In the context of inner-cities, Community Land Trusts (CLTs) conserve neighborhoods. Like their environmental and agricultural counterparts, CLTs employ use restrictions to prioritize communally beneficial development. Conserving communities, however, requires other legal tools as well. CLTs create and sustain permanently affordable homes to break the market’s bias toward socioeconomic homogeneity. CLTs also make room, literally, for green space, sites of shared culture and other productive activities that the market tends to commercialize or marginalize. By sustaining a …

A Hands-Off Approach To Religious Doctrine: What Are We Talking About?, Richard W. Garnett

Journal Articles

At the 2008 Annual Meeting of the American Association of Law Schools, the program organized by the Section on Law and Religion presented for consideration the claim that “the United States Supreme Court has shown an increasing unwillingness to engage in deciding matters that relate to the interpretation of religious practice and belief.” The Court, it was proposed, is — more and more — taking a “hands-off approach to religious doctrine.”

This proposal was, and remains, timely and important, as is illustrated by — to mention just a few, diverse examples — the ongoing property-ownership dispute between several “breakaway” Episcopal …

Public Bioethics And The Bush Presidency, O. Carter Snead

Journal Articles

Public bioethics figured prominently during the tenure of President George W. Bush. This Article explores the Bush legacy in this domain. It begins by articulating and examining the grounding norms of President Bush’s approach to public bioethics. Next, it analyzes how these norms were applied to concrete areas of concern. Building on this analysis, the next section reflects on what the President’s actions illustrate about the capacity of the Executive Branch to shape public bioethics. The Article concludes with a brief discussion of the possible metrics by which the Bush Administration’s efforts might be judged, and then offers several assessments …

The Root Of Dental Anatomy: A Case For Naming Eustachius The "Father Of Dental Anatomy"., Gregory W. Bennett

Journal Articles: College of Dentistry

When one considers the names of those whose affect on dentistry reached far beyond their lifetimes, one may think of Fauchard, Wells, Morton and Black. One name that deserves to be called among the pantheon of the greats is Bartholomaeus Eustachius. Eustachius was not the first to study the anatomy of the teeth and jaws, having been preceded by Da Vinci; however, he was the first to publish a treatise devoted entirely to this subject, Libellus de Dentibus, in 1563. As Sir William Osler, the father of modern medicine, stated: "In Science, the credit goes to the man who convinces …

Elevated Expression Of L-Selectin Ligand In Lymph Node-Derived Human Prostate Cancer Cells Correlates With Increased Tumorigenicity., Prakash Radhakrishnan, Ming-Fong Lin, Pi-Wan Cheng

Journal Articles: Biochemistry & Molecular Biology

Human prostate cancer LNCaP cells including C-33 and C-81 cells were originally derived from the lymph nodes of a patient with metastatic prostate cancer. These two cells were employed for characterization of L-selectin ligand and in vitro tumorigenicity, because they mimic the clinical conditions of early and late-stage human prostate cancer. C-81 cells exhibit higher in vitro migratory and invasive properties as compared with C-33 cells. We find that the L-selectin ligand and mucin glycan-associated MECA-79 epitope were elevated in C-81 cells. An increase of these glycotopes positively correlates with elevated tumorigenicity and expression of key glycosyl- and sulfotransferase genes. …

Steroid Analysis By Ph-Mediated Stacking Mekc, Liliya Bykova

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is based on research that led to the development and application of capillary electrophoresis method for the analysis of sex steroid hormones in the blood or plasma of fish species. The analysis of steroid hormones is essential to reveal chemical compounds that are suspected in endocrine disruption, but it is challenging due to the similarity of the chemical structures of steroids, their low concentrations, and limited volumes of plasma or blood samples in fish available for analysis. There is therefore an acute need to develop reliable accurate and systematic analytical methods applicable for the analysis of structurally similar …

Ecological Responses Of Streams To Anthropogenic Stressors, And Watershed Cause-Effect Modeling In The Mid-Atlantic Highlands Region Of The United States, Yushun Chen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Urban sprawl and related habitat disturbance and acidic deposition are major anthropogenic stressors in the Mid-Atlantic Highlands region of the United States. Little information is available about the impacts of these stressors and cause-effect relationships between these watershed stressors and stream biotic/abiotic conditions in this region. A 10-year study (1997-2006) in the Lost River watershed and a 6-year study (2002-2007) in a South Branch Potomac River watershed were conducted to assess the impacts of Corridor H highway construction on stream biotic and abiotic conditions. Also, a three-decade study (1980-2006) using data from 5 wet deposition stations and 21 major stream …

Novel Methods For Producing Cellulose Nanocrystals From Lignocellulosic Materials And Cellulose Nanocrystals Reinforced Polymer Nanocomposites, Paul Busumafi Filson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cellulose nanocrystals (nanofibers) represent a new emerging biological source of reinforcing biofillers. In this dissertation, we report the results of a study to produce cellulose nanocrystals from recycled pulp, hardwood and pine dissolving pulps using maleic acid, ultrasonic-assisted (sono-chemical treatment) and enzyme-mediated hydrolysis followed by fragmentation of cellulose crystallites using ultrasonic treatment. Additionally, the effect of two modes of heating: conventional and microwave, on enzyme-mediated and maleic acid hydrolysis were investigated. Cellulose nanocrystals yields from maleic acid hydrolysis of lignocellulosic materials were lower than that obtained from endoglucanase mediated hydrolysis of lignocellulosic materials. Sonochemical treatment of lignocellulosic materials produced both …

State-Wide Fish Tissue Contaminants Survey And Effects Of Feeding Type, Season And Gender On Fish Tissue Contamination Levels, Kenneth L. Stewart

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fish tissue fillets from benthic, predator, and mixed diet species were collected from 24 different watersheds in West Virginia. Composite samples were prepared from three to six fish fillets collected at each site, and concentrations of the chemical contaminants polychlorinated biphenyls (PCBs) and mercury were determined for each composite sample. Differences in contaminant concentrations among three major categories of feeding type (predator, benthic, and mixed diet) were examined. Differences due to species of fish and among watersheds were also examined. Predators had significantly higher mercury concentrations than benthic or mixed diet feeders and benthic feeding fish had significantly higher PCB …

Linking Land Use With Climate Change And Sustainability Topped State Legislative Land Use Reform Agenda In 2008, Patricia E. Salkin

Scholarly Works

Linking land use with climate change and sustainability topped state legislative land use reform agenda in 2008. The only discernible state land use reform trends in 2008 have focused primarily on themes surrounding sustainability. Many states pursued statutory reforms to address the strong linkages between land use and climate change, green development and affordable housing. Only one state, Michigan, focused on recodification of its planning and zoning enabling acts.

Mechanism(S) Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) Toxicity In Sea Lamprey (Petromyzon Marinus) & Rainbow Trout (Oncorhynchus Mykiss), Oana Birceanu

Theses and Dissertations (Comprehensive)

The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), has been extensively used over the last 50 years to control invasive sea lamprey (P. marinus) populations in the Great Lakes, but its mechanism of toxicity is unresolved. Due to its structural similarity to phenolic compounds known to inhibit mitochondrial ATP production, one hypothesis on the mode of action of TFM is that it impairs mitochondrial oxidative phosphorylation. A second hypothesis is that TFM targets the gill, interfering with gill ion uptake. Exposure of larval sea lamprey and rainbow trout (O. mykiss), to each animal’s respective 12-h TFM LC50, resulted in marked …

Invasive Litter, Not An Invasive Insectivore, Determines Invertebrate Communities In Hawaiian Forests, N. C. Tuttle, Karen H. Beard, W. C. Pitt

Wildland Resources Faculty Publications

In Hawaii, invasive plants have the ability to alter litter-based food chains because they often have litter traits that differ from native species. Additionally, abundant invasive predators, especially those representing new trophic levels, can reduce prey. The relative importance of these two processes on the litter invertebrate community in Hawaii is important, because they could affect the large number of endemic and endangered invertebrates. We determined the relative importance of litter resources, represented by leaf litter of two trees, an invasive nitrogen-fixer, Falcataria moluccana, and a native tree, Metrosideros polymorpha, and predation of an invasive terrestrial frog, Eleutherodactylus coqui, on …

Molecular Monitoring Of African Swine Fever Control Areas: Adult-Tick Targeted Re-Evaluation Of Mkuze Game Reserve, South Africa, L. F. Arnot, Johan T. Du Toit, A. D.S. Bastos

Wildland Resources Faculty Publications

The Mkuze Game Reserve (MGR), in north-eastern KwaZulu-Natal Province, South Africa is an African swine fever virus (ASF) controlled area. In a survey conducted in 1978, ASF prevalence in warthogs and Ornithodoros ticks in MGR was determined to be 2% and 0.06%, respectively. These values, acknowledged as being unusually low compared to other East and southern African ASF-positive sylvatic-cycle host populations, have not been assessed since. The availability of a sensitive PCR-based virus detection method, developed specifically for the sylvatic tampan host, prompted a re-evaluation of ASF virus (ASFV) prevalence in MGR ticks. Of the 98 warthog burrows inspected for …
