An Extension Of Euclidean Distance Matrix Analysis Applied To Craniofacial Growth Prediction, Mark K. Batesole

Loma Linda University Electronic Theses, Dissertations & Projects

This study is [sic] introduces a new extension of Euclidean Distance Matrix Analysis (EDMA) as applied to growth prediction analysis. Using EDMA eliminates the presupposition of a set growth pattern, which is introduced by traditional superimposition techniques. When EDMA is extended to analyze prediction methodologies, using a non-age-matched growth sample, some shortcomings become evident. These involve bootstrapping techniques, relative difference in growth, and absence of clinical, real world measure. To overcome these issues, a statistical approach using the Wilcoxen signed rank test, absolute difference in growth, and a new method to evaluate the error in a prediction methodology's landmark identification …

Nutritional Aspects Of Trans Unsaturated Fatty Acids, Mary Cantwell

Doctoral

Dietary trans unsaturated fatty acids from hydrogenated vegetable and fish oils have been shown to raise plasma low density lipoprotein cholesterol and lower high density lipoprotein cholesterol levels at 10%, 6% and 3% of energy intake. As trans fatty acid intake has not been previously assessed in Ireland a food frequency questionnaire (FFQ) was developed to assess fat intake with particular focus on trans fatty acids. A nutrient database was developed which included the fatty acid and total trans fatty acid composition of foods (measured by gas chromatography and infra-red spectroscopy) which are sources of fat in the Irish diet. …

Effects Of Ozone/Hydrogen Peroxide Pretreatment On Aerobic Biodegradability Of Nonionic Surfactants And Polypropylene Glycol, Mehmet Kitis, Craig D. Adams, John Kuzhikannil, Glen T. Daigger

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Studies were conducted which used the ozone/hydrogen peroxide (O₃/H₂O₂) advanced oxidation process to pretreat three classes of compounds prior to aerobic biological treatment. The study compounds included ethylene oxide/propylene oxide (EO/PO) block copolymers, polypropylene glycols (PPGs), linear secondary alcoholethoxylates (LSAES), and alkylphenolethoxylates (APEs). After preoxidation with ozone and hydrogen peroxide (added at their stoichiometric ratio), 300 mg/L as COD samples were bioassayed in aerobic batch bioassays with a mixed liquor suspended solids concentration of 1500 mg/L. It was found that unoxidized polypropylated compounds (EO/PO block copolymers and PPGs) and LSAEs tended to be biorecalcitrant, …

Lethal Control Of Piscivorous Birds At Aquaculture Facilities In The Northeast United States: Effects On Populations, Bradley F. Blackwell, Richard A. Dolbeer, Laura A. Tyson

United States Department of Agriculture Wildlife Services: Staff Publications

Predation by piscivorous birds is considered a substantial threat to the aquaculture industry. However, lethal control of birds at aquaculture facilities has raised concerns about the effects on the distribution and abundance of populations of the species killed. We examined the relationship between numbers of piscivorous birds reported killed under U.S. Fish and Wildlife Service (USFWS) permits at aquaculture facilities in New York, New Jersey, and Pennsylvania and species population trends within the respective states. The USFWS issued 26 permits to 9 facilities from 1985 through September 1997. Eight species appeared on permits, but only six species were reported killed: …

Measurement Of Inclusive(D(S)(±)) Photoproduction At Hera Zeus Collaboration, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J. Repond, R. Stanek, R.

The first measurement of inclusive D(s)(±) photoproduction at HERA has been performed with the ZEUS detector for photon-proton centre-of-mass energies 130 < W < 280GeV. The measured cross section for 3 < p (is perpendicular to)/(D(s)) < 12GeV and |η(D(s))| < 1.5 is σ(ep → D(s)X) = 3.79 ± 0.59(stat.) -0.46/+0.26 (syst.) ± 0.94(br.)nb, where the last error arises from the uncertainty in the D(s)(±) decay branching ratio. The measurements are compared with inclusive D*(±) photoproduction cross sections in the same kinematic region and with QCD calculations. The D(s)(±) cross sections lie above a fixed-order next-to-leading order calculation and agree better with a tree-level O(αα(s)/3) calculation that was tuned to describe the ZEUS D*(±) cross sections. The ratio of D(s)(±) to D*(±) cross sections is 0.41 ± 0.07 (stat.) -0.05/+0.03 (syst.) ± 0.10(br.). From this ratio, the strangeness-suppression factor in charm photoproduction, within the LUND string fragmentation model, has been calculated to be γ(s) = 0.27 ± 0.05 ± 0.07(br.). The cross-section ratio and γ(s) are in good agreement with those obtained in charm production in e+e- annihilation. (C) 2000 Elsevier Science B.V.

Growth And Fabrication With Single-Walled Carbon Nanotube Probe Microscopy Tips, Chin Li Cheung, Jason H. Hafner, Teri W. Odom, Kyoungha Kim, Charles M. Lieber

Barry Chin Li Cheung Publications

Single-walled carbon nanotube (SWNT) probe microscopy tips were grown by a surface growth chemical vapor deposition method. Tips consisting of individual SWNTs (1.5–4 nm in diameter) and SWNT bundles (4–12 nm in diameter) have been prepared by design through variations in the catalyst and growth conditions. In addition to high-resolution imaging, these tips have been used to fabricate SWNT nanostructures by spatially controlled deposition of specific length segments of the nanotube tips.

Determination Of The Wavelength Dependence On The Metal Catalyzed Degradation Of The Herbicide Atrazine, Timothy Bertram

Honors Theses

Since the advent of modern herbicide use in the early twentieth century, researchers have been plagued with the obvious problem of herbicide disposal. Most herbicides are specifically designed to resist natural degradation processes so that they can remain effective in the field for a substantial amount of time. In addition, they are also made water soluble so that they can be easily applied to crops. Finally, they are specifically produced to kill undesirable plant species in the quickest and often crudest fashions. Due to these specific properties herbicides pose a general threat to other organisms living in the same geographic …

Phage Therapy : An Alternative To Antibiotics, Maria A. Appeaning

Electronic Dissertations and Theses

Bacteria resistant to most or all available antibiotics are causing increasingly serious problems and raising widespread fears of returning to a pre-antibiotic era of untreatable infections and epidemics. Despite intensive work by drug companies, no new classes of antibiotics have been found in the last 30 years . There are hopes that the newfound ability to sequence entire microbial genomes and to determine the molecular bases of pathogenicity will open new avenues for treating infectious disease, but other approaches are also being sought with increasing fervor. One result is a renewed interest in the possibilities of bacteriophage (phage) therapy - …

Atmospheric Organochlorine Pesticides In The Western Canadian Arctic: Evidence Of Transpacific Transport, R. Bailey, L. A. Barrie, C. J. Halsall, P. Fellin, D. C. G. Muir

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Concentrations of hexachlorocyclohexanes (HCHs), chlordane, and dichlorodiphenyltrichloroethane (DDT) were measured in ambient air samples on a weekly basis between December 1992 and January 1995 at Tagish Yukon, Canada. In winter, unusually high air concentrations of HCHs, DDT, and chlordanes at Tagish were predominantly influenced by transpacific long-range atmospheric transport from eastern Asia that generally occurred within 5 days. HCH and heptachlor epoxide concentrations were correlated with the time that air spent over eastern Asia prior to arrival at Tagish. Chlordane and DDT, which also increase with transpacific transport, do not show a correlation with the time the upwind airshed included …

An Examination Of Gasoline Pollutants From Two-Cycle Marine Engines Within Lake Mead National Recreation Area, Brian Carter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jet skis are a very popular "toy" to have in the United States. They account for almost a third of all boat sales, and their numbers are growing rapidly. Unfortunately jet skis use two-cycle engines that pollute at unacceptable levels. Jet ski motors can emit up to 25% of its fuel right back into the water. This alarmed me and I wanted to take a deeper look into how bad jet skis pollute Las Vegas' primary water source. Lake Mead. I looked into how a two-cycle engine differs from a regular engine and I looked at the actual pollutants a …

Remote Sensing And Geographic Information Systems For Decision Analysis In Public Resource Administration: Case Study In A Southwestern Watershed, William G. Kepner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alternative futures analysis is a scenario-based approach to regional land planning that attempts to synthesize existing scientific information in a format useful to community decision makers. Typically, this approach attempts to investigate the impacts of several alternative sets of choices preferred by representative stakeholder groups relative to selected environmental or economical endpoints. Potential impacts from each of the scenarios are compared to current conditions of the region in terms of a set of processes that are modeled within a geographic information system. Future conditions are generally examined from the perspective of a recent baseline condition (versus empirically determined using a …

Ion-Kill Dosimetry, Robert Katz, F. A. Cucinotta, M. Fromm, A. Chambaudet

Robert Katz Publications

Unanticipated late effects in neutron and heavy ion therapy, not attributable to overdose, imply a qualitative difference between low and high LET therapy. We identify that difference as ‘ion kill’, associated with the spectrum of z/β in the radiation field, whose measurement we label ‘ion-kill dosimetry’.

Lead Exposure And Physiological Enzymes Among Industrial Versus Non-Industrial Workers In Al-Ain, United Arab Emirates., Fatima Rashid Mattar Said Al-Neamy

Theses

Lead, which is considered to be as a toxic metal without any useful physiological or biochemical function in human body was widely used since the evolution of the industrialized era as a chemical part of much machinery and commodities. Lead containing gasoline, lead paints, lead-soldered cans, lead-glazed earthenware and tobacco are examples of sources of lead. Therefore, lead continues to be a significant public health concern globally.

Nowadays it is particularly impossible to find a person with blood lead level lower than 0.48μmol/L (100 μg/ dL) especially in city areas. Changes in neurobehavioral, cardiovascular, hematological, and renal functions are found …

Conservation groups and land trusts can use mitigation banking to generate revenue to fund their conservation goals. General background on the Clean Water Act - Section 404 and regulations affecting wetlands, compensatory mitigation and mitigation banking is provided. Included are general problems with monitoring and enforcement of mitigation, pros and cons of preservation as compensatory …

Decision Support Methods In Diabetic Patient Management By Insulin Administration Neural Network Vs. Induction Methods For Knowledge Classification, B. V. Ambrosiadou, S. Vadera, Venky Shankaraman, D. Goulis, G. Gogou

Research Collection School Of Computing and Information Systems

Diabetes mellitus is now recognised as a major worldwide public health problem. At present, about 100 million people are registered as diabetic patients. Many clinical, social and economic problems occur as a consequence of insulin-dependent diabetes. Treatment attempts to prevent or delay complications by applying ‘optimal’ glycaemic control. Therefore, there is a continuous need for effective monitoring of the patient. Given the popularity of decision tree learning algorithms as well as neural networks for knowledge classification which is further used for decision support, this paper examines their relative merits by applying one algorithm from each family on a medical problem; …
