Studies On Inositol Polyphosphates And Their Role In Programmed Cell Death, Rakhee Agarwal Dec 2009

Studies On Inositol Polyphosphates And Their Role In Programmed Cell Death, Rakhee Agarwal

Theses and Dissertations

The agents that induce apoptosis in cancerous cells are considered as potential candidates for cancer therapy. Inositol polyphosphates, the naturally occurring compounds, regulate diverse cellular processes including induction of apoptosis in certain cancerous cells and hence can be considered as potential anticancer agents. The aim of this research dissertation was to establish firmly the role of inositol polyphosphates in induction of apoptosis by examining their mechanism of action. The overall hypothesis was that alterations in intracellular levels of inositol polyphosphates would bring about apoptotic changes. The hypothesis was tested by changing endogenous inositol polyphosphates by way of chemical treatments known …

2009 Alaska Health Workforce Vacancy Study, Beth Landon, Sanna Doucette, Rosyland Frazier, Meghan Wilson, Darla Silver, Alexandra Hill, Kate Sanders, Suzanne Sharp, Kristin Johnson, Patricia Deroche, Stephanie Martin, Donna Prator

ISER Reports

Alaska continues to experience health professional shortages. The state has long had a deficient “supply side” characterized by insufficient numbers of key health workers whose recruitment, retention, and training have been impeded by Alaska’s remoteness, harsh climate, rural isolation, low population density, and scarce training resources. Alaska is the only state without a pharmacy school and lacks its own dental and physical therapy schools as well. Health professional shortages can be decreased through the start of new training programs, the expansion of existing programs, and the improvement of the effectiveness of recruitment and retention efforts. However, strategic planning and the …

Influence Of Soil Water Repellency On Post-Fire Revegetation Success And Management Techniques To Improve Establishment Of Desired Species, Matthew D. Madsen Dec 2009

Influence Of Soil Water Repellency On Post-Fire Revegetation Success And Management Techniques To Improve Establishment Of Desired Species, Matthew D. Madsen

Theses and Dissertations

The influence of soil water repellency (WR) on vegetation recovery after a fire is poorly understood. This dissertation presents strategies to broaden opportunities for enhanced post-fire rangeland restoration and monitoring of burned piñon and juniper (P-J) woodlands by: 1) mapping the extent and severity of critical and subcritical WR, 2) determining the influence of WR on soil ecohydrologic properties and revegetation success, and 3) evaluating the suitability of a wetting agent composed of alkylpolyglycoside-ethylene oxide/propylene oxide block copolymers as a post-fire restoration tool for ameliorating the effects of soil WR and increasing seedling establishment. Results indicate that:

Age, Growth And Productivity Of Juvenile Sockeye Salmon In Two High Latitude Lakes, Alaska, Lorna I. Wilson

Fisheries

"The growth of Seward Peninsula sockeye salmon (Oncorhynchus nerka) from Salmon and Glacial lakes is related to their physical environment. Dermal scales collected over many years were measured to document the annual age specific growth of smolts and adults. The effect of fertilization on fry growth was examined using the first year of growth. The growth histories of Salmon Lake sockeye salmon were compared to Glacial Lake sockeye salmon through smolting and in the marine environment. Annual age specific fry growth had no direct relationship to fertilization; however, there were interactions between biomass of salmon prey and fertilization, and between …

Heat Transfer Performance Of Nanofluids In Facility Heating Applications, Roy T. Strandberg Dec 2009

Heat Transfer Performance Of Nanofluids In Facility Heating Applications, Roy T. Strandberg

Engineering

"Nanofluids are a class of fluids comprised of a base fluid with nanoparticles in a colloidal suspension. These fluids have been shown to exhibit substantially higher thermal conductivity than their corresponding base fluids. Investigation is required to determine if this property may be exploited for the purpose of improving the performance of systems employing liquid heat transfer. Detailed analyses of CuO/60% ethylene glycol and Al₂O₃/60% ethylene glycol nanofluids' heat transfer properties were conducted to determine if they provide a net benefit in commercial facility heating systems. The analyses employed previously developed correlations for nanofluid thermophysical, fluid dynamic and heat transfer …

Hybrid Matching And Risk Assessment Of The Misspelled Names Hmra, Cihan Varol

Theses and Dissertations

Companies acquire personal information from phone, World Wide Web, or email in order to sell or send an advertisement about their product. However, when this information is acquired, moved, copied or edited, the data may loose its quality. Often, the use of data administrators or a tool that has limited capabilities to correct the mistyped information can cause many problems. Moreover, most of the correction techniques are particularly implemented for the words used in daily conversations. Since personal names have different characteristics compared to general text, firstly, we proposed a hybrid matching algorithm (PNRS) which employs phonetic encoding, string matching …

Real Time Network Monitoring And Reporting System, Ricky Lee Massengale Sr. Dec 2009

Real Time Network Monitoring And Reporting System, Ricky Lee Massengale Sr.

Theses and Dissertations

With the ability of modern system developers to develop intelligent programs that allows machines to learn, modify and evolve themselves, current trends of reactionary methods to detect and eradicate malicious software code from infected machines is proving to be too costly. Addressing malicious software after an attack is the current methodology and should be a fallback approach. A modern approach should be to perpetually monitor the "enterprise network backbone" traffic and broadcast alerts while taking protective and pre-emptive measures, in the event that the traffic falls out of the bounds of pre-described norms. This work demonstrates that a synergy approach …

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert Dec 2009

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert

Faculty Publications

Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

Differential Phytosociological Interactions Involving Male And Female Atriplex Bonnevillensis, Jordan Sinclair, John M. Emlen, Matthew Rinella, Jessica Snelgrove, D. Carl Freeman Dec 2009

Differential Phytosociological Interactions Involving Male And Female Atriplex Bonnevillensis, Jordan Sinclair, John M. Emlen, Matthew Rinella, Jessica Snelgrove, D. Carl Freeman

Western North American Naturalist

Wind-pollinated dioecious plants often exhibit spatial segregation of the sexes. This partial niche separation has most often been explored using abiotic niche axes. However, if the sexes are truly separated in space, then they are apt to encounter different plant species that may heavily affect growth and reproduction. Also, to the extent that their niches differ, the sexes may respond differently to the same co-occurring species. Here we examine interspecific interactions that influence male and female reproductive potential in Atriplex bonnevillensis. Using Emlen's interaction assessment, a technique which assesses species interactions based on cover classes, we show that Salsola species …

Controls On Radial Growth Of Mountain Big Sagebrush And Implications For Climate Change, Rebecca E. Poore, Christine A. Lamanna, James J. Ebersole, Brian J. Enquist

Western North American Naturalist

Mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana) covers large areas in arid regions of western North America. Climate-change models predict a decrease in the range of sagebrush, but few studies have examined details of predicted changes on sagebrush growth and the potential impacts of these changes on the community. We analyzed effects of temperature, precipitation, and snow depth on sagebrush annual ring width for 1969 to 2007 in the Gunnison Basin of Colorado. Temperature at all times of year except winter had negative correlations with ring widths; summer temperature had the strongest negative relationship. Ring widths correlated …

Variation In Age And Size At Maturity Of Lake Clark, Alaska Sockeye Salmon, Elizabeth B. Benolkin Dec 2009

Variation In Age And Size At Maturity Of Lake Clark, Alaska Sockeye Salmon, Elizabeth B. Benolkin

Fisheries

Salmon returning to Lake Clark, Alaska are a valuable subsistence, commercial and ecological resource, and are an important component of the larger Kvichak River escapement. Average escapement to the Kvichak River declined sharply during 1996-2005, prompting studies to investigate age and size at maturity, key life history traits of salmon linked to reproductive success and survival. We examined potential factors which may influence sockeye salmon Oncorhynchus nerka age and size at maturity: spawning habitat and ocean environment, and examined variation in both traits over time. Sockeye salmon age and length at maturity differed among spawning locations and between brood years, …

Attenuation And Effectiveness Of Triclopyr And 2, 4-D Along Alaska Highway Rights-Of-Way In A Continental And A Coastal Subarctic Environment, David Barnes, Steve Seefeldt

AIDC Project Reports

After more than 20 years of only mechanical brush cutting, ADOT&PF evaluated the use of herbicides to manage vegetation that interferes with line-of-sight and maintenance of the roadway. While researchers have investigated herbicide effectiveness and attenuation in more-temperate climates, little study has focused on cold regions. The purpose of this project was to measure the effectiveness and attenuation of two different selective auxin-type herbicides, 2, 4 dichlorophenoxyacetic acid (2,4-D), and 3,5,6-trichloro-2-pyridinyl acetic acid (triclopyr) in two subarctic climates; an extremely cold continental climate and a maritime climate. Conclusions from this study will aid the ADOT&PF in developing a plan for …

Identification And Characterization Of Inconnu Spawning Habitat In The Sulukna River, Alaska, Jonathon D. Gerken Dec 2009

Identification And Characterization Of Inconnu Spawning Habitat In The Sulukna River, Alaska, Jonathon D. Gerken

Fisheries

Inconnu (Stenodus leucichthys) is present throughout much of the Yukon River drainage in Alaska, but only five spawning areas have been identified. Spawning habitat requirements are therefore thought to be very specific; however, the physical qualities of these habitats have only been characterized in general terms. The Sulukna River is one of five identified inconnu spawning areas within the Yukon River drainage. A systematic sampling design was used in September and October of 2007-2008 to define Sulukna River spawning locations. Presence of inconnu was identified using hook and line sampling methods and spawning was verified by catching broadcast eggs in …

Environmental Gradients And Prey Availability Relative To Glacial Features In Kittlitz's Murrelet Foraging Habitat, Mayumi L. Arimitsu

Fisheries

"The goal of this study was to characterize Kittlitz's murrelet (Brachyramphus brevirostris) foraging habitat relative to prey availability and oceanography in Kenai Fjords National Park, a glacial-marine system. I conducted oceanographic, hydroacoustic, trawl, beach seine, and marine bird surveys monthly from June-August in 2007 and 2008. High sediment load from glacial river runoff shaped the marine ecosystem, and this appeared critically important to Kittlitz's murrelets at sea. Submerged moraines influenced inner fjord habitat that was characterized by cool, fresh, stratified, and silt-laden waters. This silty glacial runoff limited light availability to chlorophyll near tidewater glaciers, but zooplankton abundance was enhanced …
