Performance-Based Plastic Design Of Earthquake Resistant Steel Structures: Concentrically Braced Frames, Tall Moment Frames, Plate Shear Wall Frames, Mohammad Reza Bayat

Civil Engineering Dissertations - Archive

It is well known that structures designed by current codes experience large inelastic deformations during major earthquakes. However, current seismic design practice in the U.S. is based on elastic structural behavior and accounts for inelastic behavior only in an indirect manner through certain modification factors such as R, I, and Cd. Under moderate to severe earthquakes, inelastic activity, including severe yielding and buckling of structural members can be unevenly distributed in the structure which may result in global collapse or costly repair work. Recently, a new design method has been developed and referred to as Performance-Based Plastic Design (PBPD). This …

Investigating The “Why” In Whypox: Explorations Of A Virtual Epidemic, Yasmin B. Kafai, Maria Quintero, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Learning scientists have created and used virtual worlds to support players’ historical, scientific, and ecological inquiries. Much less explored has been the impact of community events on players’ investigations in virtual worlds. The authors present here the case of a community event Whypox, a virtual epidemic whose annual outbreak in Whyville affects players’ communication and appearance. The authors analyze the different levels of participation ranging from casual to systematic in which players searched out more information about the Whypox, participated in online discussions about its causes and investigated different scenarios with simulations. The discussion examines ethical concerns, the contributions of …

Weedsin The Flower Garden: An Exploration Of Plagiarism In Graduate Students' Research Proposalsand Its Connection To Enculturation, Esl, And Contextual Factors, Joanna Gilmore, Denise Strickland, Briana Timmerman, Michelle Maher, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Existing literature provides insight into the nature and extent of plagiarism amongst undergraduate students (e.g., Ellery, 2008; Parameswaran & Devi, 2006; Selwyn, 2008). Plagiarism amongst graduate students is relatively unstudied, however, and the existing data are largely based on self-reports. This study investigated the rates and potential causes of plagiarism amongst graduate students in master’s and doctoral programmes in science, technology, engineering, mathematics, and science or mathematics education by examining actual research proposals written by graduate students. Results indicate that plagiarism is a prevalent issue at each of the three university sites sampled and across all of the investigated disciplines. …

Analysis Of The Suppressive Effects By Reovirus On Rotavirus Replication During Co-Infections, Melody Lyn Kiesling-Barrager

Biology Dissertations - Archive

Reovirus and rotavirus are both members of the Reoviridae family and commonly occur in children. Rotavirus induced diarrhea is one of the leading causes of death in children under the age of five worldwide. Identifying new treatment options for an unnecessarily deadly diarrheal infection caused by rotavirus would benefit hundreds of thousands of children a year. Currently, only oral rehydration therapy or costly vaccinations are available to treat or prevent rotavirus diarrhea. Even with their prevalence, little is known about how these two viruses (reovirus and rotavirus) interact when co-infecting cells. Determining these interactions could lead to new treatment options …

Time Depedent Queuing Models Of The National Airspace, Chatabush Roongrat

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Air transportation in the US system has dramatically changed in the past few decades. The National Airspace System (NAS) has increasingly become congested. A high volume of air traffic demand is one of the major challenges of the NAS. However, air traffic is very difficult to study due to many uncertainties involved. It is important that we be able to understand the relationship under uncertainties due to aviation operations, precision of navigation and control, and traffic flow efficiency. Many queuing models have been studied to better understand and quantify these relationships. In the past decade, most queuing network models assume …

Synthesis And Characterization Of Ferromagnetic Nanowires, Poching Tsai

Material Science and Engineering Theses - Archive

Ferromagnetic nanocrystals with shape anisotropy have drawn great attention in the past decades because of their unique magnetic properties and for their potential applications in ultra-high-density magnetic recording media, exchange-coupled nanocomposite magnets and related nanodevices. In this thesis, synthesis and characterixation of ferromagnetic CoNi and CoFe nanowires are reported. CoNi nanocrystals with different size, shape and composition were successfully synthesized via a catalyst chemical solution method. It was found out that the structure and morphology can be controlled by altering the NaOH concentration, and the elongation of the nanowires can be adjusted by changing surfactants ratio and catalyst amount. Unlike …

Solid-State Tunneling Spectroscopy Of Individual Quantum Dots, Ramkumar Subramanian

Material Science and Engineering Dissertations - Archive

Quantum dots are gaining importance for their potential applications in the fields of energy harvesting, bio-labeling and treatment, in opto-electronic devices and in photonic devices. For all these applications, it is imperative to know their electronic structure. Although currently several spectroscopic techniques exist to study the electronic structure of these quantum dots, they are accompanied by other effects and do not give purely the electronic structure of the individual quantum dot. The main goals of this research are to:o To study the energy level structure of `single' quantum dots.o Develop a new spectroscopic technique that allows the measurement of the …

The microstructures of the thin films were initially studied using X-ray diffraction. Detailed microstructure information such as crystallite of the films, grain size, epitaxial quality, crystallographic structure and film/substrate interface were studied using high-resolution transmission electron microscope (HRTEM). More specifically, Effects …

Incorporation Of Vascular Endothelial Growth Factor And Pleiotrophin Into A Multiluminal Biosynthetic Nerve Implant For The Repair Of Peripheral Nerve Long Gap Defects, An Hai Nguyen

Bioengineering Theses - Archive

To repair a fully transected nerve without putting undue tension on the nerve stumps, and too circumvent many of the obvious problems of using harvested nerve grafts synthetic nerve guides have been used in the clinical setting. Thus far this strategy has met with minimal success for the repair of short defects (i.e. 1 - 2.5 cm) while any defect larger than 3 cm have failed. We hypothesize that neurotorphic support, early vascularization, and contact guidance are needed to successfully regenerate a nerve across a long-gap defect. To this end we proposed a biosynthetic nerve implant (BNI) with a multiluminal …

The Promotion Of Pediatric Sensory Integration Using Small Animals In A Clinical Or Classroom Environment: A Resource For Occupational Therapists, Nina Perez Jackson

Occupational Therapy Capstones

The purpose of this scholarly project was to create and provide a program to assist occupational therapists in setting up, managing, and providing animal assisted activities and therapies (AAA/T) as a useful conjunction with sensory integration therapy.

A review of the literature revealed a lack of information for occupational therapists to provide AAA/T with children. The research revealed that the use of sensory integration therapy as a pre-established framework to implement AAA/T would provide a research based platform to present a program incorporating animals into therapy.

Based on the literature findings, a product was developed to guide occupational therapists in …

Ethnography Of Chronic Pain Experiences Of Enlisted Women, Linda M. Denke

Nursing Dissertations - Archive

The American Pain Foundation reported in 2006 that 32% of military men and women with chronic pain reported that military culture is a barrier to pain care and receiving pain care jeopardized their career. Pain management required a series of understandings about pain in the military that motivated enlisted women's pain perceptions, pain behaviors, and pain relief strategies. The seen and unseen factors were ever-present in military life and contributed to the chronic pain experiences of enlisted women but to what degree was largely unknown. This ethnographic approach produced brief illustrations of pain beliefs, attitudes, and behaviors that enlisted women …

Resting Electromyographic Activity Of Deep Thoracic Transversospinalis Muscles Identified As Abnormal With Palpation, Gary Fryer, Michael Bird, Barry Robbins, Christian Fossum, Jane C. Johnson

All KCOM Faculty Publications

Context: In the 1940s, osteopathic researchers suggested that paraspinal tissue abnormality was associated with spontaneous muscle activity, but few studies have since re-examined these reports. Objective: To determine whether abnormal motor activity plays a role in deep paraspinal tissues that appear abnormal to palpation. Methods: Using an observational study design, the PVG of participants with thoracic pain were palpated by two examiners for consensus on the most marked level of tissue abnormality. Dual fine-wire, intramuscular electrodes were inserted into the deep transversospinalis (multifidus, rotatores) muscles at the abnormal level and at two normal sites (above and below the abnormal level). …

Snakeweed Patch Vegetation Quad Data At The Sevilleta National Wildlife Refuge, Nm (1984, 1996), Douglas I. Moore, Herb Grover, James Gosz

Sevilleta LTER Program Data

In 1984, a research project was initiated on a relatively small disturbance patch just south of Deep Well. This disturbance was thought to be the result of an old praire dog town, probably dating back to when a nearby ranch was active, and a lot of old mammal mounds remained in the disturbed area. One of the things that made the disturbance patch particularily noticeable was the lush growth of snakeweed (Gutierrezia sarothrae) within the patch. This prompted the designation of the disturbance patch as the "snakeweed patch" or "Gutierrezia patch." In addition, there was an obvious increase in bare …

Electric Power Distribution Expansion Planning Using Distributed Generation Sources And Storages, Ruben R. Avagyan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electric Power Distribution Expansion Planning (PDEP) is concerned with finding the best topology of the power distribution grid and component sizing such that power demand at each load bus is satisfied and some objectives are optimized. In this research, a new integrated time-phased problem is considered, where demand changes through the planning horizon and distributed generation sources and energy storages are integrated into the planning process. The growth of power demand in consecutive periods may require an upgrade of existing or construction of new substations and/or feeders during the planning time-span. An alternative solution to meet the growing demand and …

Selected Studies Of Orbital Stability And Habitability In Star-Planet Systems, William Jason Eberle

Physics Dissertations - Archive

The study of planets remaining in orbit around one star with another starinterfering is an important topic of orbital mechanics and astrobiology. The onset of instability for a planet which is part of a stellar binary system is investigated by performing numerical simulations of the circular restricted three body problem. Synodic velocity phase space portraits are used with the hodograph in order to obtain a new criterion for determining planetary stability. The stability limits obtained via these methods agree with previous methods that were obtained based on simulations over much longer time intervals. In addition, the timely case of a …

Synthesis Of Cdte And Pbs Semiconductor Quantum Dots And Their Biological And Photochemical Applications, Xing Zhang

Physics Theses - Archive

Semiconductor quantum dots are inorganic nanoparticles with unique photophysical properties. In particular, water soluble quantum dots which have been synthesized by colloidal chemistry in aqueous environment are highly luminescent. Their huge absorption cross sections, tunable, narrow emission bands and effectiveness of surface functionality have stimulated these luminescent probes in various applications like biological sensors as well as imaging contrast agents. In this paper we will discuss several aspects about the synthesize processes of the water soluble, highly luminescent type of CdTe quantum dots and its near infrared counterpart HgxCd1-xTe, the extremely crystallized PbS quantum dots with the application of the …

Search For Standard Model Higgs In Two Photon Final State At Atlas, Hyeon Jin Kim

Physics Dissertations - Archive

The Standard Model of particle physics describes very precisely the nuclear strong and weak forces and the eletromagnetic interaction, by the exchange of vector bosons. It also describes all matter as composed of quarks and leptons and predicts their interactions. The Higgs boson is the last missing piece of the Standard Model, yet to be observed. The search for the Higgs particle is one of the most important goals of the ATLAS experiment at the Large Hadron Collider (LHC). The ATLAS electromagnetic (EM) calorimeter is a crucial subdetector system of the ATLAS detector in searching for the Higgs boson, in …

The Role Of The Y-Component Of The Interplanetary Magnetic Field In Transpolar Saturation And Ring Current Response As Found In Data And Simulation, Elizabeth Joy Mitchell

Physics Dissertations - Archive

Energy is transferred into the magnetosphere of Earth through merging of magnetic fields (Dungey cycle and lobe cell convection) and through momentum transfer across the magnetopause (viscous interactions). These processes cause enhanced plasma convection in the inner magnetosphere and ionosphere, which in turn form the ring current and the transpolar potential, respectively. These processes have been studied extensively with regard to the role of the north-south component of the interplanetary magnetic field (IMF). The role of the dawn-dusk IMF is less well known.We use the LFM global MHD simulation, the CRCM, and data to quantify the transpolar potential and ring …

Michigan’S Upper Peninsula Immigrants And Their Occupations As Seen In The 1910 Federal Census, Russel Magnaghi

Other

From the Introduction:

While conducting this work I developed the idea of going through the 1910 Federal census of the Upper Peninsula and listing the population of the immigrants and their occupations. Why the 1910 census? This census was the high-water mark for immigrant population in the Upper Peninsula. After that date people left for the auto industry in southern Michigan and the natural resources of the region were on the decline which caused more people to leave.

An Application Of A Modified Experiential Learning Model For A Higher Education Course: Evidence Of Increased Outcomes, Mark F. Roark, Jonathan C. Norling

Kinesiology and Health Science Faculty Publications

This case study applied a modified Experiential Learning Theory (ELT) model in an undergraduate outdoor recreation management course. The Kolb (1984) ELT model was modified to accommodate the higher education learning processes suggested by L. B. Sharp (1943), Sugarman (1985) and Greenaway (1995). Results indicate evidence of increased student learning. Quantitative results from a retrospective pre/posttest evaluation of change score means in learning outcomes supported the study hypotheses that 1) the application of a modified ELT model affects the outcomes of planning, knowledge/skills, and potential for transfer of learning and 2) previous trip experience affects these outcomes. A secondary analysis …

Playful Experiences: Measure Youth Outcomes In Parks And Recreation, Mark F. Roark, F. Evans

Kinesiology and Health Science Faculty Publications

Do you like to play or know anyone else who likes to play? Play has forever been a seminal focus for recreation and parks programs. When designing and implementing experiences for youth participants, we typically measure our success by how much fun youth had. These days, while play and the outcome of fun are still meaningful to youth, stakeholders expect outcomes beyond fun. From season to season, many of us now hear parent voices asking, “What will my children gain from your program?” or “Why is yours better? What makes yours unique?” City council members ask us to justify the …

The State of Utah has one of the highest food insecurity rates in the nation. It is ranked in the top 4% in the nation of being food insecure and 34% of the state is considered low-income, defined as at or below 185% of poverty level (LeBlanc, Christofferson, & Christensen, 2008). These trends place Utah’s low-income population at increased risk of obesity and chronic disease. The Center of Hunger and Poverty reported a high rate of obesity among low-income individuals, with hunger, poverty, and obesity frequently occurring at the same time (USDA, 2009). With limited income, quantity is often more …

Traces, Boundaries, Surfaces: An Investigation Through Art Practice Of Institutional Sites With Particular Reference To A Former Lunatic Asylum, Sarah Bennett

Other Faculty of Arts, Humanities and Business Theses

This doctoral research project by art practice examines a former site of exclusion, a nineteenth-century county pauper lunatic asylum, in particular its methods of containment and coercion. It involves an initial unearthing of narratives relating to the site's histories, including its recent redevelopment as a gated residential community, and consideration of other similar institutional settings. An exploration is subsequently developed through appropriation and interrogation of spatial and durational processes involved in selected mechanisms of control, and the impact of their repetition on those present, constituting the core of this practice-based research, and evidenced in the artworks arising from the enquiry. …

Importance Of Contact Chemical Cues In Host Recognition And Acceptance By The Braconid Larval Endoparasitoids Cotesia Sesamiae And Cotesia Flavipes, Meshack Obonyo, Fritz Schulthess, Bruno Le Ru, Johnnie Van Den Berg, Jean François Silvain, Paul André Calatayud

All Peer-Reviewed Publications

The ability of the congeneric braconid parasitoids Cotesia sesamiae (Cameron) and Cotesia flavipes Cameron to discriminate between stemborer larval cues upon contact was studied using their natural hosts, namely the noctuid Busseola fusca (Fuller) and the crambid Chilo partellus (Swinhoe), respectively, and the pyralid non-host Eldana saccharina (Walker). When the natural host larvae were washed in distilled water, parasitoid behavior was similar to that displayed when in contact with E. saccharina, characterized by the absence of ovipositor insertion. When washed host or non-host larvae were bathed with water extracts of their natural host, the parasitoids showed a significant increase in …

All Peer-Reviewed Publications

Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats. In this study we explored the possibility of using Anopheles gambiae sensu stricto as bio-reporters for environmental heavy metal pollution through expressions of their metal-responsive metallothionein and α-tubulin genes. The study was undertaken with third instar larvae after selection by cadmium, copper, or lead at LC30 through five successive generations. Expression levels were determined in the 5th generation by semi-quantitative RT-PCR on the experimental and control populations. The data were analyzed using one-way ANOVA. The highest metallothionein (F3, 11=4.574, P=0.038) and α-tubulin (F3, 11=12.961, P=0.002) responses …
