Coarse Bedload Routing And Dispersion Through Tributary Confluences, Kurt Imhoff, Andrew C. Wilcox

Geosciences Faculty Publications

Sediment routing fundamentally influences channel morphology and propagation of disturbances. However, the transport and storage of bedload particles in headwater channel confluences, which may be significant nodes of the channel network in terms of sediment routing, morphology, and habitat, is poorly understood. To characterize routing processes through confluences of headwater channels, we investigate how sediment routing patterns through headwater confluences compare to those described in low-gradient gravel bed river systems, and how confluences affect the dispersive behavior of coarse bedload particles compared to non-confluence reaches. We address these questions with a field tracer experiment using passive-integrated transponder and radio-frequency identification …

Development And Preliminary Evaluation Of A Spray Deposition Sensing System For Improving Pesticide Application, Melissa A. Kesterson, Joe D. Luck, Michael P. Sama

Biosystems and Agricultural Engineering Faculty Publications

An electronic, resistance-based sensor array and data acquisition system was developed to measure spray deposition from hydraulic nozzles. The sensor surface consisted of several parallel tin plated copper traces of varying widths with varying gap widths. The system contained an embedded microprocessor to monitor output voltage corresponding to spray deposition every second. In addition, a wireless module was used to transmit the voltage values to a remote laptop. Tests were conducted in two stages to evaluate the performance of the sensor array in an attempt to quantify the spray deposition. Initial tests utilized manual droplet placement on the sensor surface …

A "Case" Study On Developing Science Communication And Outreach Skills Of University Graduate Student Researchers In Alaska, Molly E. Tedesche, Laura Conner, Jennifer Danielson

Research Posters

Well rounded scientific researchers are not only experts in their field, but can also communicate their work to a multitude of various audiences, including the general public and undergraduate university students. Training in these areas should ideally start during graduate school, but many programs are not preparing students to effectively communicate their work. Here, we present results from the NSF-funded CASE (Changing Alaska Science Education) program, which was funded by NSF under the auspices of the GK-12 program. CASE placed science graduate students (fellows) in K-12 classrooms to teach alongside of K-12 teachers with the goal of enhancing communication and …

From Boolean Equalities To Constraints, Sergio Antoy, Michael Hanus

Computer Science Faculty Publications and Presentations

Although functional as well as logic languages use equality to discriminate between logically different cases, the operational meaning of equality is different in such languages. Functional languages reduce equational expressions to their Boolean values, True or False, logic languages use unification to check the validity only and fail otherwise. Consequently, the language Curry, which amalgamates functional and logic programming features, offers two kinds of equational expressions so that the programmer has to distinguish between these uses. We show that this distinction can be avoided by providing an analysis and transformation method that automatically selects the appropriate operation. Without this distinction …

"I Don't Think Of All The Misery, But Of The Beauty That Still Remains": Holocaust Education In The Music Classroom, Kathryn Eileen Stiadle

Honors Theses

On June 26, 2014, Pennsylvania Governor Tom Corbett signed a law requiring mandatory Holocaust and Genocide education in all Pennsylvania schools. This legislation, the result of efforts made by Holocaust author and advocated Rhonda Fink-Whitman, made Pennsylvania the sixth state to require Holocaust and Genocide education. However, the law does not state how to teach about this rather difficult topic. According to anthropologist and ethnomusicologist Alan Merriam, one of the functions of music in any society is "emotional expression." Because music gives us the ability to convey emotions in a way that speech perhaps cannot, it is a beneficial tool …

A Comparison Of High-Intensity Power Training And Graded Treadmill Exercise, Eric Peter Sparks

Research Papers

The purpose of this study was to investigate acute blood lactate concentration, heart rate, blood pressure, and rating of perceived exertion following two different types of exercise: a high intensity power training exercise test and a graded treadmill exercise test. The hypothesis was that the HIPT exercise test would yield higher levels of blood lactate, heart rate, blood pressure, and RPE, immediately post exercise when compared to a graded treadmill exercise test. Ten college-aged participants with a body mass index /m², blood pressure <140/90 mmHg, no overt cardiovascular disease, no cardiovascular medications, and no use of tobacco products were included in the study. All participants had a general fitness and training level that allowed them to perform the exercise bouts without any hesitation. Subjects participated in two exercise sessions on separate occasions. A graded treadmill exercise test occurred with the subjects walking on the treadmill until the self-stated desire to stop or until five stages of increased speed and intensity had occurred. In the second meeting, subjects completed a prescribed high-intensity power training exercise test. Heart rate (HR), rating of perceived exertion (RPE), blood pressure (BP), and blood lactate concentration were all obtained before and immediately following each training session, as well as immediately following each stage of the graded treadmill exercise test. Oxygen uptake was obtained during the graded treadmill exercise test. After both tests were conducted, the high intensity power training exercise test showed a higher percentage of blood lactate concentration at its conclusion when compared to the graded treadmill exercise test with lower final average values BP, HR and RPE. In conclusion HIPT exercise yields higher blood lactate concentrations compared to graded treadmill exercise with a lower blood pressure, heart rate, and perceived exertion.

Trophic Pathways Supporting Juvenile Chinook And Coho Salmon In The Glacial Susitna River, Alaska: Patterns Of Freshwater, Terrestrial, And Marine Resource Use Across A Seasonally Dynamic Habitat Mosaic, Kristin M. Rine

Biological Sciences

In large, seasonally dynamic and spatially complex watersheds, the availability and relative importance of various food resources for stream fishes can be expected to vary substantially. While numerous studies have attempted to uncover the trophic linkages that support stream salmonids, much of these efforts have occurred at small scales that disregard variability of food resources inherent in lotic systems. This study aimed to determine large-scale patterns in the contributions of freshwater, terrestrial, and marine-derived food resources to juvenile Chinook and Coho salmon (Oncorhynchus tshawytscha and O. kisutch) in the large, glacially influenced Susitna River, Alaska. I quantified diet patterns both …

Income-Tested College Financial Aid And Labor Disincentives, Rajeev Darolia

Upjohn Institute Working Papers

Working has become commonplace among college students; however, this activity can have unexpected financial consequences. Federal formulas implicitly tax the amount of financial aid students are eligible to receive by as much as 50 cents for each marginal dollar of income. This tax creates an incentive for college students to reduce income, though abstruse formulas and the timing of financial aid receipt are likely to limit responses. Using data from a national sample of financially independent college students in the United States, I do not find that students bunch below earnings protection thresholds in a manner that would indicate attempts …

Nevada Supreme Court Summaries

The Court determined that employees who are terminated from employment for absence due to incarceration, and are later convicted of a crime, are not eligible for unemployment benefits. These employees are contrasted with those who are incarcerated, but remained incarcerated due to indigence, or were not convicted due to unsupported charges. The latter group may be eligible for unemployment benefits.

Pathological Brain Detection By A Novel Image Feature—Fractional Fourier Entropy, Shuihua Wang, Yudong Zhang, Xiaojun Yang, Ping Sun, Zhengchao Dong, Aijun Lu, Ti-Fei Yuan

Publications and Research

Aim: To detect pathological brain conditions early is a core procedure for patients so as to have enough time for treatment. Traditional manual detection is either cumbersome, or expensive, or time-consuming. We aim to offer a system that can automatically identify pathological brain images in this paper.Method: We propose a novel image feature, viz., Fractional Fourier Entropy (FRFE), which is based on the combination of Fractional Fourier Transform(FRFT) and Shannon entropy. Afterwards, the Welch’s t-test (WTT) and Mahalanobis distance (MD) were harnessed to select distinguishing features. Finally, we introduced an advanced classifier: twin support vector machine (TSVM). Results: A 10 …

Space Use And Movements Of Moose Hunters And Wolves In The Yukon Flats, Alaska, Ian Johnson

Biological Sciences

Within the Yukon Flats, Alaska, subsistence communities utilize moose (Alces alces) as a primary resource (78% of households) and wolves (Canis lupus) hunt them as an obligatory prey item. Hence, understanding the potential of direct or indirect competition between wolves and humans is useful for managers. In Chapter 1, I used a novel approach utilizing spatially-linked interviews to quantify the distance subsistence users were traveling from communities and rivers to harvest moose in the Yukon Flats. My study was the first to quantify hunter access in the Arctic and may provide managers with a harvest estimation approach that may supplement …

Linkages Between Protein Ubiquitination, Proteasome Activity And The Expression Of Oxygen-Binding Proteins In Antarctic Notothenioid Fishes, Corey A. Oldham

Biological Sciences

Antarctic icefishes lack hemoglobin (Hb), and some species lack cardiac myoglobin (Mb). As iron-centered proteins, Hb and Mb can promote the formation of reactive oxygen species that may damage biological macromolecules. Consistent with this, we find higher levels of oxidized proteins in some tissues of red-blooded notothenioids than in icefishes. Oxidized proteins are marked for degradation by the conjugation of the protein ubiquitin. I hypothesized that levels of ubiquitinated proteins and 20S proteasome activity (which degrades oxidized proteins) would be higher in +Hb and +Mb notothenioids than icefishes lacking the proteins. Levels of ubiquitinated proteins and rates of proteasome activity …

Non-Invasive Methods For Obtaining Occupancy Probabilities And Density Estimates Of Interior Alaska's Mesocarnivore Populations, Casey Pozzanghera

Biological Sciences

Mesocarnivore species worldwide have been shown to be significant drivers of ecological communities. Changes in their abundance and distributions are known to cause cascading effects throughout ecosystems, and changes to the landscape and climate will likely lead to shifts in mesocarnivore population sizes and distributions. However, the current status of these species in some of the world's most susceptible landscapes is not known. I assessed the impacts of abiotic factors on the distributional patterns and abundance of boreal mesocarnivores and evaluated methods commonly used to estimate density and occupancy. I conducted non-invasive winter surveys of coyotes (Canis latrans), red foxes …

Comparison Of Lower Body Segment Alignment Of Elite Level Hockey Players To Age-Matched Non-Hockey Players, Jim R. Kimbal

Biological Sciences

Lower body overuse and insidious onset injuries are thought to have an underlying biomechanical component which may be predisposing to injury. The purpose of this study was to compare lower body biomechanical characteristics for elite hockey players to matched controls. I hypothesize that elite hockey players have a greater degree of anterior pelvic tilt, greater varus knee angle, a higher foot arch and feet held in parallel more during gait than a matched non-skating population. Measures were taken of elite level, college aged, male hockey players and compared to cross country runners (ten subjects in each group) who served as …

Studies In The History Of Anthropology In The United States, Jay H. Bernstein

Publications and Research

I will talk about a study I did on the first persons to do Ph.D.s in anthropology and how the project led to my leaving the anthropology profession and becoming a librarian. The project began in a biographical study of a little-known anthropologist that involved archival work. As a librarian who has left the profession of anthropology (not without trauma), I remain keenly interested in the history and bibliography of anthropology and view dissertation projects as crucial to understanding the biographies of scholars and trends in academic professions.

Synergistic Effects Among Leading Indicators Of Construction Safety Management, Matthew E. Calhoun

Engineering

Safety performance in the construction industry has improved significantly since the Occupational Safety and Health Act was enacted in 1970. Despite these improvements, annual accident statistics indicate the construction industry remains one of the most dangerous for workers. However, there are some construction companies that defy these statistics and have an exemplary safety record. Many of these companies have adopted a zero-accident vision and measure their safety performance using both leading and lagging indicators. Safety performance has traditionally been measured with only lagging indicators that have included recordable injury rates, experience modification rates, days-away-restricted-transferred, among many others. Unfortunately these indicators …

Studies On Thermophysical Properties Of Nanofluids And Their Application In Ground Source Heat Pump, Jagannadha Reddy Satti

Engineering

The goals of this dissertation were to measure the thermal conductivity, specific heat, and density of different propylene glycol nanofluids; compare the results with existing correlations; and develop new correlations with the obtained data. A numerical study has been performed to study the benefits of nanofluids in cold climate ground source heat pumps. Nanofluids are dispersions of nanoparticles with average sizes of less than 100 nm in heat transfer fluids such as water, oil, ethylene glycol, and propylene glycol. In cold regions, the common heat transfer fluids used are ethylene glycol (EG) and propylene glycol (PG). In the present research, …

Ubiquitin Goes Green, Zhihua Hua, Richard D. Vierstra

Biology Faculty Research

Chloroplasts depend on the nucleus for much of their proteome. Consequently, strong transcriptional coordination exists between the genomes, which is attuned to the developmental and physiological needs of the organelle. Recent studies highlight that the post-translational modifier ubiquitin adds another layer to plastid homeostasis and even helps eliminate damaged chloroplasts.

Resource Competition, Space Use And Forage Ecology Of Sea Otters, Enhydra Lutris, In Southern Southeast Alaska, Zachary N. Hoyt

Fisheries

The growing sea otter population in southern Southeast Alaska is impacting commercial shellfish, through foraging and expanding in range and abundance except where hunted for subsistence. Sea otters and their prey have coexisted in the North Pacific Ocean for approximately 750,000 years, but due to exploitation of sea otters from the 1770s until 1911, the species became extinct over much of its range, including southern Southeast Alaska. Subsequently, invertebrate species flourished and were commercially targeted in the late 1900s. Sea otters were relocated (n = 106) to southern Southeast Alaska in 1968. In this dissertation, I evaluated this marine mammal-fisheries …

Criminal Records And Immigration: Comparing The United States And The European Union, Dimitra Blitsa, Lauryn P. Gouldin, James B. Jacobs, Elena Larrauri

Fordham International Law Journal

Because the revolution in information technology has made individual criminal history records more comprehensive, efficient, and retrievable, an individual’s criminal history has become an ever more crucial marker of character and public identity. The broad range of collateral consequences of criminal convictions has become a very salient issue for criminal justice scholars and reformers. A single criminal conviction can trigger thousands of potentially applicable restrictions, penalties, or other civil disabilities. There is no better example of this phenomenon than immigration law and policy, where developments in data storage and retrieval converge with opposition to immigration, especially to immigrants who bear …

Knowledge, Attitudes, And Intentions Toward Fertility Awareness And Oocyte Cryopreservation Among Obstetrics And Gynecology Resident Physicians, L. Yu, Brennan Peterson, M. C. Inhorn, Julia K. Boehm, P. Patrizio

Marriage and Family Therapy Faculty Articles and Research

STUDY QUESTION What knowledge, attitudes and intentions do US obstetrics and gynecology (OB/GYN) residents have toward discussing age-related fertility decline and oocyte cryopreservation with their patients?

SUMMARY ANSWER Most OB/GYN residents believe that age-related fertility decline, but not oocyte cryopreservation, should be discussed during well-woman annual exams; furthermore, nearly half of residents overestimated the age at which female fertility markedly declines.

WHAT IS KNOWN ALREADY Oocyte cryopreservation can be utilized to preserve fertility potential. Currently, no studies of US OB/GYN residents exist that question their knowledge, attitudes, and intentions toward discussing age-related fertility decline and oocyte cryopreservation with patients.
