Nano Composite Piezo-Responsive Foam Enabled Pressure Mapping, Jake Duane Sundet

Theses and Dissertations

Pressure injuries cause pain both physically and financially. By creating a comfortable pressure mapping system, pressure injuries can more easily be prevented, and a large expenditure avoided. Nano composite piezo-responsive foam (NCPF) is an inexpensive foam that can be used to measure a static load while still providing a comfortable interface. As NCPF compresses, the impedance changes, correlating to a change in pressure. Optimizing electrode geometry is needed to take full advantage of the impedance change NCPF incurs upon deformation. To optimize electrode geometry, a design of experiment was performed which concluded that a one square inch area of interlaced …

Digital Libraries As Digital Third Place: Virtual Programming In The Age Of Loneliness, Stephen Craig Finlay, Jenny Haddon

Criss Library Faculty Proceedings & Presentations

Brick-and-mortar libraries are commonly cited as examples of “third places:” community building spaces outside of home and work which embody qualities of equity and access without placing demands upon those who use them. However, as libraries increasingly invest in digital services, can they continue to serve in that role through virtual programming? Amid what public health officials are currently referring to as a “loneliness epidemic,” with the highest self-reported rates of loneliness and social isolation measured since sociologists began tracking it in the 1970s, the community-building role of libraries is perhaps more essential than ever. While much has been written …

Application Of Icp Rie Techniques To Produce Cnt Arrays, Mujtaba Yar Khan Siddiqui

Theses

Introducing biomolecules into cells is an important process in the field of gene therapy and in developing cures for debilitating illnesses such as HIV and cancer. However, the currently used methods for cellular transfection are slow, inefficient and expensive, causing them to be restrictive. A solution to this problem would be the carbon nanotube (CNT) array devices developed by our research group, which have been shown to be highly efficient at transporting biomolecules into cells. In the current manufacturing process, a sacrificial template with vertically aligned nanopores is used to deposit carbon in, the template then is etched away to …

Examining Paleoshorelines In The Eastern Gulf Of Mexico: Insights On Sea Level History And Potential Areas Of Interest For Habitat Management, Catalina Rubiano

USF Tampa Graduate Theses and Dissertations

An inventory of multibeam bathymetry containing relict drowned and lithified paleoshorelines has been compiled and analyzed in the first ever shelf-wide investigation of paleo sea level indicators on the west Florida shelf (WFS). On the largest scale, the WFS is a wide and gently sloping terrain that is characterized by a carbonate-rich sediment regime. This framework coupled with the region’s tectonic stability provided a setting in which sea level changes since ~ 20 ka have been recorded to a remarkable degree of resolution in the form of paleoshorelines which formed at sea level and were subsequently drowned and preserved in …

Active Transportation Counts From Existing On-Street Signal And Detection Infrastructure, Sirisha Kothuri

PSU Transportation Seminars

The goal of agencies is to provide a safe and reliable multimodal transportation system that connects people and helps communities and economy thrive. In order to fulfill this mission, it is important to have a robust understanding of the usage of each mode within the system as well as the linkages between modes. Currently there is no systemic accounting of pedestrian traffic across the transportation network, making it difficult to understand systemic crash safety and prioritize projects. Analysts must rely on imperfect proxies such as land use density, race, income, and transit usage in the absence of measured pedestrian traffic …

China Maritime Report No. 32: The Pch191 Modular Long-Range Rocket Launcher: Reshaping The Pla Army's Role In A Cross-Strait Campaign, Joshua Arostegui

CMSI China Maritime Reports

With its fielding of the PCH191 multiple rocket launcher (MRL) and its variety of long-range precision munitions, the PLA Army (PLAA) has become arguably the most important contributor of campaign and tactical firepower during a joint island landing campaign against Taiwan. No longer simply the primary source of amphibious and air assault forces, the PLAA is now capable of using its multiple battalions of PCH191 MRLs to support maritime dominance, the joint firepower strike, and ground forces landing on Taiwan’s shores and in depth. The Chinese ordnance industry has developed multiple low-cost rockets, an anti-ship cruise missile, and a tactical …

Integrated Periphyton Biofilters In Marine Recirculating Aquaculture Systems, Adam N. Bell

USF Tampa Graduate Theses and Dissertations

Marine aquaculture is a growing industry that has the potential to reduce eutrophication, overfishing, and loss of biodiversity. Recirculating aquaculture systems (RAS) are a type of aquaculture system that decreases discharge, raises biological control, and conserves water; however, RAS are challenged due to high energy cost, low biodiversity, water quality control, and waste nutrients. Periphyton biofilters are a new technology that allows for feed production, water quality control, microbial diversity, and resource recovery in marine aquaculture systems. The overarching question that this dissertation investigates is, how can periphyton biofilters be integrated into RAS to address the challenges of modern sustainable …

Optimal Inverter-Based Resource Installation To Minimize Technical Energy Losses In Distribution Systems, Felipe B. Dantas, Damasio Fernandes, Washington L.A. Neves, Alana K.X.B. Branco, Flavio Costa

Michigan Tech Publications

This paper proposes an algorithm for the optimal installation of inverter-based resources (IBR) composed of wind energy conversion systems, photovoltaic systems, and battery energy storage systems in distribution systems using genetic algorithm (GA) and the cuckoo search (CS) as optimization techniques. The OpenDSS software is used to calculate the power flow in the distribution system with different penetration levels of IBRs. It is used a standard load shape of the IEEE 123 bus system programmed in OpenDSS and irradiance, temperature, and wind speed curves from Brazil. The proposed algorithm, using a genetic algorithm and cuckoo search, was able to define …

Synthetic Aperture Scatter Imaging, Qian Huang, Zhipeng Dong, Gregory Nero, Yuzuru Takashima, Timothy J. Schulz, David J. Brady

Michigan Tech Publications

Diffraction limits the minimum resolvable feature on remotely observed targets to $\lambda R_{c}/A_{c}$, where $\lambda$ is the operating wavelength, $R_{c}$ is the range to the target and $A_{c}$ is the diameter of the observing aperture. Resolution is often further reduced by scatter or turbulence. Here we show that analysis of scattered coherent illumination can be used to achieve resolution proportional to $\lambda R_{s}/A_{s}$, where $R_{s}$ is the range between the scatterer and the target and $A_{s}$ is the diameter of the observed scatter. Theoretical analysis suggests that this approach can yield resolution up to 1000× better than the diffraction limit. …

Diagnostic And Commensal Staphylococcus Pseudintermedius Genomes Reveal Niche Adaptation Through Parallel Selection Of Defense Mechanisms, Sanjam S Sawhney, Rhiannon C Vargas, Meghan A Wallace, Carol E Muenks, Brian V Lubbers, Stephanie A Fritz, Carey-Ann D Burnham, Gautam Dantas

2020-Current year OA Pubs

Staphylococcus pseudintermedius is historically understood as a prevalent commensal and pathogen of dogs, though modern clinical diagnostics reveal an expanded host-range that includes humans. It remains unclear whether differentiation across S. pseudintermedius populations is driven primarily by niche-type or host-species. We sequenced 501 diagnostic and commensal isolates from a hospital, veterinary diagnostic laboratory, and within households in the American Midwest, and performed a comparative genomics investigation contrasting human diagnostic, animal diagnostic, human colonizing, pet colonizing, and household-surface S. pseudintermedius isolates. Though indistinguishable by core and accessory gene architecture, diagnostic isolates harbor more encoded and phenotypic resistance, whereas colonizing and surface …

A Novel Application Of Spinning Disk Technology To Collect Plasma From Whole Blood Prior To Quantifying Plasma Rna, Naomi Rapier-Sharman, Mae-Lynn L. Hutchinson, Carlos M. Moreno, Abraham Quaye, Brian D. Poole, K. Scott Weber, William G. Pitt, Brett E. Pickett

Faculty Publications

The spinning disk technology has previously been utilized to isolate bacterial components from blood in hours instead of days. We hypothesized that this platform could be applied as an alternative approach to isolating plasma RNA from a whole blood sample. We consequently tested the efficacy of the spinning disk technology to extract plasma from whole blood upstream of RNA isolation and analysis. To do so, we collected plasma using either the spinning disk or the typical two-spin centrifuge method. We found that the spinning disk method results in significantly more hemolysis during collection than the conventional two-spin centrifuge method. However, …

Library Users’ Attitudes Towards Virtual Library And Information Services In Ugandan Public And Private Universities, Lydia Namugera, Joyce Bukirwa, Constant Okello-Obura

Library Philosophy and Practice (e-journal)

Technological advancements, innovations, research, changing user needs, and online education have significantly affected traditional libraries. The 21st-century has engendered library users who seldom visit physical libraries but rely on alternative sources of information like Google from their convenient locations. This implies that for libraries to effectively adapt to the technologically driven academic landscape, adoption of Virtual Library and Information Services (VLIS) is the most feasible approach for them to fulfill their mandate of information provision. However, despite the numerous benefits VLIS offers, such as timely and convenient access to a wide range of current electronic resources, its adoption, implementation and …

Effects Of Running On Femoral Articular Cartilage Thickness For Anterior Cruciate Ligament Reconstruction Patients And Non-Aclr Control Subjects, Aubree L. Remmel, Hyunwook Lee, Minsub Oh, Seunguk Han, Steven P. Allen, Garritt L. Page, Dustin A. Bruening, Robert D. Hyldahl, J. Ty Hopkins, Matthew K. Seeley

International Journal of Exercise Science: Conference Proceedings

Anterior cruciate ligament reconstruction (ACLR) patients are more likely to develop posttraumatic knee osteoarthritis than non-ACLR counterparts. The effect of running on femoral articular cartilage thickness is unclear. PURPOSE: The purpose of this study was to compare how 30 minutes of running influences femoral articular cartilage thickness for ACLR patients and non-ACLR control subjects. We hypothesized that running would deform the femoral articular cartilage more for the ACLR patients than for the control subjects. METHODS: We recruited 20 individuals with primary unilateral ACLR and 20 matched non-ACLR controls. ACLR patients and control subjects were matched based upon age, gender, BMI, …

In The Beginning: Rousseau’S Discourse On The Origin Of Inequality & The Socialist Book Of Genesis, Steven Kessler

Journal of Ideology

The following article makes the connection between the work and thought of Jean-Jacques Rousseau and socialism. Rousseau invalidated the concept of original sin where God punished man with labor. Not only did he invalidate original sin in his personal life, but he went a step further: he invalidated the entire creation myth from the Book of Genesis. Rousseau then supplanted that creation myth with his own origin story, one he outlined in great detail in an essay called, This Discourse on the Origin of Inequality. This work contains the creation myth of socialism, and is the socialist book of …
