Agricultural Applications For Electromagnetic Exposure, H. Aliakbarian, A. Enayati, H. Ameri Mahabadi, M.A. Soltani Dec 2007

Agricultural Applications For Electromagnetic Exposure, H. Aliakbarian, A. Enayati, H. Ameri Mahabadi, M.A. Soltani

Research Publications (2006 to 2010)

Despite the advances in bug controlling and antifreezing operations of agricultural products, the devastation of Sunne pests and freezing is still enormous. Traditional treatments such as chemical insecticides for bug controlling and covering to avoid freezing have not been sufficient. In the presented paper, new ideas of using electromagnetic treatment for anti-freezing operation, pre-harvest Sunne pest control, and Orchid flower control are introduced.


Analysis Of Hg And Stable Isotope Concentrations In Bald Eagle Feathers From The Great Lakes And Voyageurs National Park, Minnesota, Jennifer Thomsen Dec 2007

Analysis Of Hg And Stable Isotope Concentrations In Bald Eagle Feathers From The Great Lakes And Voyageurs National Park, Minnesota, Jennifer Thomsen

All Theses

Bald eagles (Haliaeetus leucocephalus) feed on a variety of aquatic and terrestrial wildlife. As top predators in their food chain, they may accumulate harmful concentrations of pollutants such as mercury, which can have detrimental effects on populations of this species. The stable isotope composition of feathers provides useful information about the food resources assimilated by bald eagles. The connection between mercury, (Hg), concentration and stable isotope concentration ( 13C and 15N) of feathers were measured to better understand the potential sources and pathways of Hg uptake by bald eagles living in the Great Lakes region of Michigan and Voyageurs National …

The Programmed Death-1 And Interleukin-10 Pathways Play A Down-Modulatory Role In Lp-Bm5 Retrovirus-Induced Murine Immunodeficiency Syndrome, Kathy A. Green, Taku Okazaki, Tasuku Honjo, W. James Cook, William R. Green Dec 2007

The Programmed Death-1 And Interleukin-10 Pathways Play A Down-Modulatory Role In Lp-Bm5 Retrovirus-Induced Murine Immunodeficiency Syndrome, Kathy A. Green, Taku Okazaki, Tasuku Honjo, W. James Cook, William R. Green

Dartmouth Scholarship

Pathology due to the immune system's response to viral infections often represents a delicate balance between inhibition of viral pathogenesis and regulation of protective immunity. In susceptible C57BL/6 (B6) mice, the murine retroviral isolate LP-BM5 induces splenomegaly, hypergammaglobulinemia, profound B- and T-cell immunodeficiency, and increased susceptibility to opportunistic pathogens and terminal B-cell lymphomas. Here, we report that B6.PD-1 (programmed death-1) and B6.IL-10 knockout mice are substantially more susceptible to LP-BM5-induced disease than wild-type B6 mice. LP-BM5-infected B6.PD-1−/− mice developed more severe splenomegaly, hypergammaglobulinemia, and immunodeficiency than infected B6 mice: PD-1−/− mice are more susceptible to lower doses of …


Cosolvent Effects On The Reductive Dechlorination Of Tetrachloroethylene Catalyzed By Iron Tetraphenyl Porphyrin Chloride, Lavanya Ramasubramanian Dec 2007

Cosolvent Effects On The Reductive Dechlorination Of Tetrachloroethylene Catalyzed By Iron Tetraphenyl Porphyrin Chloride, Lavanya Ramasubramanian

All Theses

Abiotic electron transfer mediated reductive dechlorination reactions have been studied extensively in the past decade. Porphyrins and metalloporphyrins are common electron transfer mediators used. Past studies have shown that some metalloporphyrins play a key role in increasing the rate of reaction in the presence of cosolvents. There have also been suggestions that organic cosolvents enhance the rate of reduction by increasing the solubility of metalloporphyrins.
The primary objective of this project was to examine the effect of cosolvents on the metalloporphyrin-catalyzed reductive dechlorination of tetrachloroethylene (PCE). Subsequently, experiments were also conducted to test the hypothesis that metalloporphyrin solubility is linked …


Rendering Principal Direction Contour Lines With Oriented Textures, Kelly Gallagher Dec 2007

Rendering Principal Direction Contour Lines With Oriented Textures, Kelly Gallagher

All Theses

In this paper we explore the use of contour lines in computer graphics as a means of conveying shape to the end-user. Contour lines provide an alternative to traditional realistic rendering styles and may even provide a more appropriate visualization for certain situations. For our images, contour line orientation is established in accordance with principal curvature directions.
We present a method for rendering a texture, oriented in the principal curvature direction, across a traditionally-modeled geometric surface that effectively forms suggestive contour lines to enhance the visualization of that surface. We further extend the method to create animated contour textures, wherein …


Woody Invasive Plant Species Occurrence And Abundance As, Jyoti Patnaik Dec 2007

Woody Invasive Plant Species Occurrence And Abundance As, Jyoti Patnaik

All Theses

The spread of invasive plants is one of the most challenging ecological problems in the 21st century, causing a $35 billion loss per year to the economy in the United states alone. More than 85% of woody invasive species were introduced originally for ornamental and landscape use. As a result, over the last few decades, perennial woody invaders have appeared in fence rows, rights-of-way, old fields, understories, and the canopies of eastern forests of the United States. Besides the information about the geographical distribution, general biological characteristics, and response to herbicides, very little information is available on the occurrence and …


Risk Characterization For Boron And Aquatic Plants And Animals, Basma Damiri Dec 2007

Risk Characterization For Boron And Aquatic Plants And Animals, Basma Damiri

All Theses

In aqueous mixtures, boron can be toxic to plants or animals at relatively low concentrations. Boron may occur at concentrations that can pose risk to plants used in constructed wetland treatment systems designed to treat constituents of concerned in a complex matrix such as flue gas desulfurization water and boron may adversely affect survival, growth, and consequently, plant performance. The three major objectives of this research are: 1) to measure responses of Typha latifolia (seed germination and root and shoot elongation) and Schoenoplectus californicus early seedlings (survival, and shoot and root elongation) to aqueous exposures of boron in diluted FGD …


Leisure Constraints: Multiple Hileararchy Stratification Perspectives , Yunjin Tae Dec 2007

Leisure Constraints: Multiple Hileararchy Stratification Perspectives , Yunjin Tae

All Theses

The disadvantaged groups (elderly, gender, minorities, and individuals of lower SES) suffer from inequality of leisure participation. This study explores the theoretical frameworks of multiple hierarchy stratification in order to better understand the perceived constraints of leisure activities according to socio-demographic variables and how single and multiple statuses influence an individual's participation in leisure activities.
This study explores the relationship between leisure constraints and socio-demographic variables using cross tabulation, and investigate net effects of socio-demographic variables and combined effects of socio-demographic variables in two different types of leisure activities using binary regression.
The findings suggest that the disadvantaged groups have …


Importance And Availability Of Content And Communication Skills Among Entry-Level Interpretive Naturalists, Jonathan Ivey Dec 2007

Importance And Availability Of Content And Communication Skills Among Entry-Level Interpretive Naturalists, Jonathan Ivey

All Theses

Interpretation seeks to help visitors to make intellectual and emotional connections between themselves and park resources through a communication process. To accomplish this goal, interpreters must be intimately knowledgeable of park resources as well as excellent communicators. The details of what types of knowledge and communication skills are most important to interpretive naturalists have not been formally documented. Likewise, little is formally known about the availability of each skill in pools of entry-level applicants for interpretive positions. This study documented the varying importance and availability of content and communication skills for entry-level interpretive naturalists, based on the perceptions of experienced …

An Economic Model For Bioprospecting Contracts, Helen Ding, Paulo Nunes, Laura Onofri Dec 2007

An Economic Model For Bioprospecting Contracts, Helen Ding, Paulo Nunes, Laura Onofri

Fondazione Eni Enrico Mattei Working Papers

This paper explores the use of a micro-economic model to analyse the provisions and parties of bioprospecting contracts. It focuses on the pharmaceutical industry as the representative biodiversity buyer, presenting an original theoretical framework that explains the main contract characteristics or stylised facts. Against this background, it considers the main contractors involved in these private contracts, i.e. biodiversity sellers and biodiversity buyers, analysing both the magnitude and distribution of the respective payoffs. Particular attention is devoted to the different, mixed impacts of bioprospecting contracts and patenting on social welfare. The positive welfare impacts delivered by bioprospecting contracts are associated with …

Constructed Wetlands For The Landscape Nursery Industry: Nutrient Assimilation And Removal, Sarah White Dec 2007

Constructed Wetlands For The Landscape Nursery Industry: Nutrient Assimilation And Removal, Sarah White

All Dissertations

Runoff from nursery operations is considered a potential non-point source contamination. Water quality and quantity are quickly becoming important factors that drive management practices at these facilities. Constructed wetland systems (CWS) are a management tool that can be used by nursery operations to improve water quality both for recycling within nursery production areas and for eventual release from nursery production areas into surrounding surface waters. The overall goal of this research was to optimize nutrient removal efficiencies in CWS. To accomplish this goal, I characterized the following: (1) the P sorption and desorption capacity of several substrates; (2) the effect …

The Firm Size, Farm Size, And Transaction Costs: The Case Of Hazelnut Farms In Turkey, Ibrahim Demir Dec 2007

The Firm Size, Farm Size, And Transaction Costs: The Case Of Hazelnut Farms In Turkey, Ibrahim Demir

All Dissertations

ABSTRACT This study analyzes the determinants of the size of the hazelnut farms in Turkey within the framework of the theory of firm and transaction costs. This study argues that, for a farm production function, land is a complex input with many transaction cost-increasing interactions with nature. Natural effects, such as land slope and variation in the weather conditions, can increase transaction costs. Transaction costs are the costs of using the inputs necessary for production. This study utilizes two separate data sets in order to test if the predicted relationship between transaction costs and farm size holds. The first data …


A Breakdown In Boundaries: As Explored Through Abjection And The Language Of Abstract Art, Mary Hanley Dec 2007

A Breakdown In Boundaries: As Explored Through Abjection And The Language Of Abstract Art, Mary Hanley

All Theses

ABSTRACT
My work places emphasis on the anxiety and allure felt at the possibility of ingesting an object belonging to or displaced from the body through the language of abstract art. It links the fears and fascinations felt in situations of perceived abnormality and bodily aggression, to the objectification, or conversely abjection, of objects through images. I investigate a collapse in division between what the perceived identity of a thing or person is, and what it is not.
Each painting rejects an ideal of beauty as portrayed through stability, clarity, and compartmentalization, and embraces beauty as the interconnectedness of opposing …


Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs Dec 2007

Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs

All Theses

I examined parent and nestling behavior during early chick rearing in Brown Pelicans (Pelecanus occidentalis) nesting at a colony in Charleston Harbor, South Carolina during the 2006 breeding season. There were significant differences in the frequency of feeding, attendance, and chick aggression according to chick age, although the pattern differed among behaviors. The rate of adult feeding, chick feeding and adult attendance all decreased with chick age while chick aggressive behavior peaked when chicks were ca. 21 d post-hatch. I found that nests with at least one juvenile parent had a lower average clutch size, hatch rate, and number of …


Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park Dec 2007

Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park

All Dissertations

Beginning with the development of an embryo and throughout one's adult life angiogenesis plays an essential role for organ growth and repair. The balancing of pro-angiogenic factors to anti-angiogenic factors is what regulates the process of angiogenesis. When this balance is disrupted in one direction or the other, numerous disorders can occur including ocular and inflammatory diseases and, in particular, tumor growth and metastasis. Therefore, inhibition of angiogenesis has become an effective therapy for arresting the growth of tumors.
A key regulator of angiogenesis involves vascular endothelial growth factor (VEGF) and its receptor, VEGFR-2 (KDR). The binding of VEGF to …


Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci Dec 2007

Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci

All Dissertations

The family Hydropsychidae is nearly ubiquitous in streams and rivers, with over 1600 described species worldwide. Hydropsychidae is ecologically important and its larvae play key roles as indicators of water quality. Conflicting morphological characters have obscured the evolutionary history of the subfamilies, and the wide diversity of phallic morphology among Hydropsyche sensu lato species has created unstable classification systems that have been disputed among authors. My research used five nuclear ribosomal and mitochondrial COI fragments to infer a molecular phylogeny for Hydropsychidae subfamilies and genera, focusing particularly on the Hydropsychinae and the Hydropsyche sensu lato lineage. The monophyly of four …


Ddasaccident548, Hd-Aid Dec 2007

Ddasaccident548, Hd-Aid

Global CWD Repository

The deminer was investigating the signal and excavating by sitting/squatting position and his prodder/bayonet detonated the PMN mine. The evidence on site shows that the excavation of the signal started from the first mark, and not 30cm back from the indication. The bayonet directly touched the mine causing a detonation. This indicates he was not conducting operations with the correct procedure.

Porcine Intestinal Epithelial Cell Lines As A New In Vitro Model For Studying Adherence And Pathogenesis Of Enterotoxigenic Escherichia Coli, Seung Y. Koh, Sajan George, Volker Brozel, Rodney A. Moxley, David H. Francis, Radhey Kaushik

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) infections result in large economic losses in the swine industry worldwide. The organism causes diarrhea by adhering to and colonizing enterocytes in the small intestines. While much progress has been made in understanding the pathogenesis of ETEC, no homologous intestinal epithelial cultures suitable for studying porcine ETEC pathogenesis have been described prior to this report. In the current study, we investigated the adherence of various porcine ETEC strains to two porcine (IPEC-1 and IPEC-J2) and one human (INT-407) small intestinal epithelial cell lines. Each cell line was assessed for its ability to support the adherence of …


Comparison Of Compost Tea And Biological Fungicides For Control Of Early Blight In Organic Heirloom Tomato Production, Richard Kouyoumjian Dec 2007

Comparison Of Compost Tea And Biological Fungicides For Control Of Early Blight In Organic Heirloom Tomato Production, Richard Kouyoumjian

All Theses

The efficacy of compost tea was evaluated and compared alone and in combination with two biofungicides Serenade Max and Sonata for control of early blight caused by the fungal pathogen Alternaria tomatophila on tomato Solanum lycopersicum (L), heirloom cultivar `Cherokee Purple'. Results of field experiments over two growing seasons indicated that compost tea provided a low level of protection against early blight. The results were variable; most likely due to dry conditions and the presence of bacterial wilt the first year and tomato spotted wilt virus the second year. In both 2006 and 2007 field trials compost tea was not …
