Positive Solutions For Rural Solid Waste Management, Jessica L. Meyer

Rural Development

Rural solid waste management is and will continue to be one of the leading environmental problems facing the twenty-first century. As the global south, under developed, and developing countries progress, proper solid waste management must be a priority to keep humans and ecosystems healthy and safe. This study provides an overview of the Republic of Macedonia's solid waste management and the discoveries of public and environmental health risks as a result of unsanitary landfills and illegal dumping. These problems are caused by low enforcement of environmental laws, minimal governmental and public support, as well as lack of funding and infrastructure. …

Remote Sensing Of Browning Trends In The Alaskan Boreal Forest, Mary Elizabeth Parent

Forest Sciences

Vegetation health can be monitored using a time series of remotely sensed images by calculating the Normalized Difference Vegetation Index (NDVI). We assessed temporal trends throughout an NDVI time series with three sensors: Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat Thematic Mapper/Enhanced Thematic Mapper Plus (TM/ETM+). There has been debate over the reliability of AVHRR sensor NDVI data in the circumboreal region. Therefore, the purpose of this paper was to first use MODIS and Landsat TM/ETM+ data and assess declining trends within twelve Landsat scene footprints across boreal Alaska and second use Landsat …

The Fate Of Nitrogen Pollution In High-Latitude Winter: Investigations Using A 1-D Photochemical Model, Patrick L. Joyce

Chemistry and Biochemistry

Simulations using a 1-D photochemical model were performed to analyze the fate of NOx pollution in a high-latitude winter environment. Modeled pollution emissions were constrained by observations from downtown Fairbanks and the model reproduced dilution of NOx on timescales in agreement with field measurements on the edge and outside of the urban area of Fairbanks. The model was updated from previous versions to include calculations of reactions of N₂O₅ on aerosol particles and an empirically-derived value for dry deposition velocity of N₂O₅ to the snowpack, which acts as a competing loss of N₂O₅. It was found that dry deposition of …

Nicotine Sensitization And Brain-Derived Neurotrophic Factor Content In Adolescent Rats Neonatally Treated With Quinpirole., Addie Roberts

Undergraduate Honors Theses

Neonatal treatment of quinpirole in rats increases dopamine D2-like receptor sensitivity over the animal’s lifetime, a phenomenon referred to as D2 priming. Male and female Sprague-Dawley rats were given quinpirole (1mg/kg, i.p.) or saline on postnatal days (P)1-21. After habituation to a locomotor arena on P29-31, beginning P33, animals were administered nicotine (0.3 mg/kg, 0.5 mg/kg, or 0.7 mg/kg, i.p.) or saline and placed into a locomotor arena for behavioral testing every second day for a total of 9 treatments. The results showed that adolescents neonatally treated with quinpirole produced more enhanced sensitization to nicotine than controls. Brains tissues were …

7,8-Dihydroxyflavone, A Selective Tyrosine Kinase Receptor B Agonist And Bdnf Mimic, Promotes Angiogenesis., Jeremy Williams

Undergraduate Honors Theses

7,8-dihydroxyflavone (7,8-DHF), which is a member of the flavonoid family, is a selective tyrosine kinase receptor B (TrkB) agonist that has neurotrophic effects in various neurological diseases such as ischemic stroke and Parkinson’s disease [3]. In this study, we assessed the angiogeneic effect of 7,8-DHF in endothelial cells derived from resistance vessel of the brain. Angiogenesis by 7,8-DHF is an important factor that helps prevent and treat various ischemic diseases. In this study, we found that rat RV cells used in the experiment possess the TrkB receptor. Our data also demonstrates that 7,8-DHF is able to stimulate cell proliferation in …

Brain-Derived Neurotrophic Factor Levels In D2 Receptor Primed Adolescent Rats Given Twice Daily Nicotine Administrations., Josie Minnigh

Undergraduate Honors Theses

Nicotine use is very prevalent in the schizophrenic population, which is a 2.5 fold greater than the general population. In the present study, the drug quinpirole (dopamine D2/D3 agonist) or saline was given neonatally to 25 Sprague-Dawley male and female rats. Rats were randomly assigned to condition. Beginning postnatal day 33 animals were given twice daily administrations of nicotine (0.5 mg/kg free base). After the first of the daily injections they were placed in a locomotor arena every other day for behavioral testing. One day after behavioral testing, the dorsal striatum and nucleus accumbens were removed for brain-derived neurotrophic factor …

Knowledge Of The Effects Of Alcohol On Fetal Development Among Women Of Childbearing Age., Mary Bales

Undergraduate Honors Theses

While Fetal Alcohol Syndrome Disorder is a recognized problem with alcohol ingestion during the formation of facial features, Fetal Alcohol Spectrum Disorders are not as widely recognized. These disorders result from exposure to alcohol throughout pregnancy when the brain and nervous system are developing. The resulting disorders include attention deficit disorders, social disorders, inappropriate behaviors, learning disorders, and intellectual disability. The incidence of children with alcohol-related disorders is increasing as evidenced by children needing special services in the educational systems. It is unknown how much alcohol ingestion is safe during pregnancy or how genetic factors are involved in the development …

Ninety percent of children in the United States will have experienced the loss of a significant loved one by the time they are 18 years old (McClure, 2007). Parents and other family members can provide a significant amount of support, provided that they are equipped with the necessary resources. The purpose of this project was to identify and develop tools that provide parents and other family members with the opportunity to learn ways to incorporate themselves as a support system for a grieving child in their family. Children express their feelings by showing rather than telling. Creativity allows bereaved children …

Hydrographic Controls And Seasonal Variability On The Carbonate System In The Northern Gulf Of Alaska, Kristen L. Shake

Marine Biology

The Northern Gulf of Alaska (GOA) supports a dynamic and economically viable marine ecosystem. One notable potential stressor to this ecosystem is ocean acidification (OA), a byproduct of the increased uptake of anthropogenic carbon dioxide (CO₂) by the ocean. Measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) were made along the continental shelf of the northern GOA and in Prince William Sound (PWS) and used to calculate seawater pH and the saturation state of aragonite Warp). Observations showed a high degree of seasonal variability in DIC concentrations in surface and bottom waters. TA was depleted relative to DIC …

Free Clinics And The Uninsured: The Need For Remote Area Medical In Central Appalachia After Health Reform., James W. Watson

Electronic Theses and Dissertations

In 2008, the election of President Barack Obama brought health care to the forefront of national discussions and led to the passage of the Patient Protection and Affordable Care Act (ACA). The legislation changed the rules of health care delivery in the United States, but the ACA did not do one fundamental thing: It did not end the need for many of the nation's most needy patients to seek free medical care from groups such as Remote Area Medical (RAM).

A mobile clinic, RAM brings together volunteer dentists, physicians, nurses, and other professionals as well as support staff for multi-day …

Neither A Borrower Nor A Lender Be: America Attempts To Collect Its War Debts 1922-1934., James Chambers

Electronic Theses and Dissertations

During and immediately after World War I the United States lent over $10 billion to various countries to sustain their war efforts and to provide post-war relief. The United States's insistence that these loans be repaid led to sharp disagreements with its erstwhile allies as to the nature of these loans and whether they should actually be repaid.

This thesis examines the processes, and the policies upon which those processes were based, by which the United States attempted to compel the debtor nations to begin repaying their loans.

The central theme of the thesis was developed largely from primary sources, …

Synthesis Of Resveratrol Esters And Aliphatic Acids., Stanley Mofor Jing

Electronic Theses and Dissertations

Resveratrol (RV) is a naturally occurring phytoalexin of the stilbenoid family produced by some plant species, and present in grape skin, peanuts, and red wine. It has been found to exhibit anti-cancer, anti-inflammatory, anti-viral, anti-aging, cardio protective, and anti-oxidant properties. Bioavailability is a huge setback that limits the potentials of RV. As a result, efforts have been made to design and synthesize RV esters and aliphatic acids in an attempt to increase its bioavailability, solubility in water, and possibly improving its biological activities. Resveratrol esters, 3,5,4'-triacetyloxystilbene (2) and Methyl 1,1',1''- (3,4',5-stilbenyl)-1,6-hexanedioate (3) have been synthesized. Compound 3 is a new …

Effects Of The Age-Composition Of Spawning Sockeye Salmon On Future Returns Of Sockeye Salmon To Bristol, Bay, Alaska, Janelle C. Mueller

Fisheries

The age structure of sockeye salmon on spawning grounds is highly variable, yet little is known about the influence of spawner age composition on subsequent abundance and age composition of recruits. Management of Bristol Bay sockeye salmon relies on estimated spawner abundance to determine escapement goals, without regard to age or size composition. This may not accurately reflect reproductive potential as a basis for setting escapement goals. Parental age structure and environmental conditions were included as independent variables in statistical models to evaluate their effects on the age structure of their progeny. In addition, relationships between spawner age composition and …

Mesoporous Functionalized Materials For Post-Combustion Carbon Dioxide Capture., Kolade Omoniyi Ojo

Electronic Theses and Dissertations

Novel highly functionalized hybrid organic-inorganic materials were synthesized by polycondensation of bis[3-(trimethoxysilyl)propyl]amine in presence of cationic and anionic surfactants. Reaction media strongly affected gelation time. Thus, in basic media gelation occurred immediately while acid increased gelation time. Material structures were studied by IR spectroscopy, porosimetry, XRD, and SAXS methods. In spite of the absence of an inorganic linker, obtained bridged silsesquioxanes had mesoporous structure. A material prepared in the presence of dodecylamine as a template had higher surface area and narrow pore size distribution while the use of sodium dodecylbenzene sulfate resulted in formation of mesopores with wide size ranges. …

Hydrodynamics Of Downstream Pointed Guidevanes: A Case Study Of The Hess Creek Meander Bend Realignment, Alexandre W. Lai

Engineering

The hydrodynamics of downstream pointed guidevanes installed to realign an eroding meander bend upstream of the Trans- Alaska Pipeline bridge is studied. The bridge is located at Hess Creek, 137 km north of Fairbanks, Alaska. Effect of the downstream pointed vanes on bed form, erosion, longitudinal and transverse slopes, three dimensional velocity profiles, flow patterns, and other hydraulic parameters for high and low flows are compared and analyzed. Six years after installation of the vanes the realigned thalweg remains in its original design location. The longitudinal bed profile changed from a dominant continuous pool typical of natural meander bends on …

The Book of Enoch stands as substantial proof that …

Talking Heads: How Broadcast Media Frame The Public Relations Industry., Samara Rose Litvack

Electronic Theses and Dissertations

Researchers conducted a content analysis to measure framing of the public relations industry in 354 English language broadcast transcripts from the United States, Canada, and Australia from Sept. 1, 2009 to Aug. 31, 2010.

The overall tone toward public relations was strongly negative. Mentions reflected one-way forms of communication and mentions of the pejorative term "PR" appeared more frequently than mentions of "public relations". The profession was almost always mentioned within the body of the broadcast, as opposed to the headline or the lead paragraph.

Exploratory research showed 15 shows that included negative mentions 100% of the time. Additionally, 27 …

The Digital Folklore Project: Tracking The Oral Tradition On The World Wide Web., Jasen Bacon

Electronic Theses and Dissertations

I collected forty-two e-mail forwards over the course of four months, and from those I formulated a framework that adapts existing theory in collection and study of real-world folklore to the emerging folk communities that exist on the internet. Through this analysis I prove that the same genres of folklore that is routinely collected by folklorists have been adapted to fit the digital environment of the internet. I then use the framework that I lay out to perform a study of the e-mails themselves.

Reproductive Ecology And Morphometric Subspecies Comparisons Of Dunlin (Calidris Alpina), An Arctic Shorebird, Heather River Gates

Biological Sciences

The Arctic region provides globally important breeding and migratory habitat for abundant wildlife populations including migratory shorebirds. Due to their remote breeding locations, basic information on breeding ecology, annual productivity, and factors that regulate their populations are poorly studied. Wildlife biologists managing migratory bird populations require detailed information on avian breeding biology, in addition to information on migration ecology including connectivity of migratory stopover and wintering locations. To address information gaps in fecundity, I conducted an experimental study investigating the renesting ecology of Dunlin (Calidris alpina arcticola) by removing clutches at two stages of incubation and by following adults marked …

Terrestrial Invertebrate Prey For Juvenile Chinook Salmon: Abundance And Environmental Controls In An Interior Alaska River, Laura Gutierrez

Biological Sciences

Terrestrial prey subsidies can be a key food source for stream fish, but their importance and environmental controls on their abundance have not been widely documented in high latitude ecosystems. This study investigated terrestrial invertebrate prey availability and predation by age-0+ juvenile chinook salmon (Oncorhynchus tshawytscha), overlap between terrestrial infall and drift to diet, and the relationship between diet to stream temperature and discharge in the Chena River, Interior Alaska. Terrestrial infall, drift, and juvenile chinook diet varied widely through the summers (May-September) of 2008 and 2009. Drift was comprised of 33% terrestrial and 67% aquatic invertebrate mass, while juvenile …

Novel Fungal Taxa In An Alaskan Boreal Forest: Phylogenetic Affinities, Ecologies, And Ribosomal Rna Secondary Structures, Daniel Glass

Biological Sciences

Phylogenetic analyses suggest that a novel DNA sequence (NS1) found in a boreal forest soil-clone library belongs to the fungal kingdom but does not fall unambiguously within any known class. In order to determine if NS1 codes for an authentic ribosomal RNA (rRNA) gene-copy, I modeled ribosomal RNA secondary structure for four gene regions. Such analyses have never been used on environmental ribosomal sequences before. It appears that NS1 does code for an authentic gene-copy and is not a biological or lab artifact. I also elucidated the habitat preferences, horizon preferences, and fine-scale spatial structure of NS1 using molecular methods. …

Clinical Coverage Of An Archetype Repository Over Snomed-Ct., Sheng Yu, Damon Berry, Jesus Bisbal

Articles

Clinical archetypes provide a means for health professionals to design what should be communicated as part of an Electronic Health Record (EHR). An ever-growing number of archetype definitions follow this health information modelling approach, and this international archetype resource will eventually cover a large number of clinical concepts. On the other hand, clinical terminology systems that can be referenced by archetypes also have a wide coverage over many types of health-care information.

No existing work measures the clinical content coverage of archetypes using terminology systems as a metric. Archetype authors require guidance to identify under-covered clinical areas that may need …
