    Performance Prediction Analysis for Aero-Naut CAM Folding Propellers and its Application into CREATeV Solar Aircraft
    Performance Prediction Analysis for Aero-Naut CAM Folding Propellers and its Application into CREATeV Solar Aircraft
    This paper investigates the performance prediction method for Aero-Naut CAM folding propellers through parametric studies of existing wind tunnel testing data. The application of the propeller into CREATeV ultra-long-endurance unmanned solar aircraft necessitated the availability of accurate performance estimates for its propeller-motor configurations. Performance coefficient prediction method based on scaling relationship of propeller geometry is discussed along with motor efficient prediction method and iterative propeller-motor performance optimization. Several important observations regarding performance scaling effect of Aero-Naut folding propellers and its impact on performance optimization are discussed. The resulting optimized propeller selections are proposed which would enhance mission capability of CREATeV. Finally, future work considerations and concluding remarks of the analysis is presented.

    Prospects of CRISPR/Cas cloning vectors to combat antibiotic resistance gene dissemination
    Prospects of CRISPR/Cas cloning vectors to combat antibiotic resistance gene dissemination
    CRISPR (Clustered Regularly Interspaced Small Palindromic Repeats) and Cas (CRISPR associated) proteins comprise an adaptive immune system in prokaryotes CRISPR Cas systems digest invading nucleic acids and incorporate a 30 bp snippet (“spacer") of the invader into the host genome Spacers are transcribed into CRISPR RNAs (crRNA's) that recognize the same nucleic acid in the event of a repeat invasion and guide nucleases to the target for elimination We hypothesize that a plasmid vector, when transformed into a host cell, could exogenously express a CRISPR/Cas system and prevent the host’s participation in conjugative processes, Ing, R., Gilbride, K.

    Qualitative assessment of worker productivity and experience in office environments
    This project is a study on the building impact of occupant’s productivity and well being in an office environment. Presented through an office case study, the work takes part of a larger pre- and post-move study carried out over the course of a year. The study collects, analyses, and compares numerous sources of data in a pre- and post-move study: 1) environmental data using desk sensors 2) online qualitative surveys of user comfort relative to location in the office 3) an architectural assessment of the spaces in the office. The collection of both pre- and post-move data is intended to allow findings to be compared to understand the impacts of environmental design on worker productivity and building performance and address the challenges in conducting successful pre- and post-move assessments., Cepic, M.

    RBS moment connection analysis using a solid model
    RBS moment connection analysis using a solid model
    The unpredictability of the steel beam welding connection has led to many solutions, including the are of focus for this research Reduced Beam Section ( Moment Connections The RBS in steel moment connection facilitates the calculation and predictability of failure in design The RBS section is created by cutting out part of the flanges in a beam This creates a plastic hinge where the beam will fail first 1 This creates a model of predictability on the durability and strength of the beams Creating a RBS connection increases the overall ductility of the steel frame The RBS section reduces the flange width which causes stress concentration on the reduced section and this then lowers the stress on the welds. The lower stress then prevents unexpected brittle fracture in the welding a predicted plastic deformation of the RBS section during a seismic event 2 3 The research is focused on optimizing the RBS connection Finite models will be created using ANSYS to investigate how different RBS connections react in different situations and what is the most efficient design in terms of safety and cost., Coello-Mena, M.

    Revealing the voices of women living with IBD
    Revealing the voices of women living with IBD
    The purpose of this exploratory study is to center the voices of women who are living with inflammatory bowel disease (IBD) in order to understand their lived experiences and the kinds of support and resources they most value. Our review of the literature has indicated that studies which reveal the personal, lived, qualitative experiences with women with IBD are scarce. Instead, the existing body of research tends to be highly medicalized and expert-driven. In this study we constructed a sample of 20 YouTube videos posted by women living with Crohn's Disease and Ulcerative Colitis, who openly shared their experiences of living with the disease. Using phenomenology, coupled with an intersectional lens, we explored how living with IBD, was informed by gender, race, class and age. We hope to publish this exploratory work as a way to begin to address the gap in our understanding of the lived experiences with IBD., Sebastian, S., Perreault-Laird, J., Silver, S. (October, 2019).

    Soil and sediment analysis for agricultural and arctic landscapes
    Soil and sediment analysis for agricultural and arctic landscapes
    Soil plays in integral role in our terrestrial ecosystems. It is the membrane between the atmosphere and the biosphere. Soils provide a medium for vegetation, a filtration system for water, and contain the essential minerals and nutrients plants require (ref). Soil is composed of living (biotic) and non-living (abiotic) material. Soil development is a dynamic and ongoing process that depends on local climate, parent material, topography, vegetation, and time. The size of the inorganic mineral particles within a soil is referred to as grain size. Soil grain size is classified as Clay if the particle diameter is <0.002 mm, as silt if it is between 0.002 mm and 0.06 mm, or as sand if it is between 0.06 mm and 2 mm (Figure). The texture of a soil, or the distribution of particle grain size, can be a determining factor on how the soil drains or retains water, and its ability to retain nutrients, and its susceptibility to erosion, all of which can be direct factors in the development of natural vegetation or crop suitability. To classify a particular soils texture the proportions of particle size (% Sand, % Silt, % Clay) of a given sample is required. The use of a standard method is essential in order to compare data obtained at different locations (ref). A well-developed method for determining the quantitative proportions of particle size is the hydrometer method. Additionally, local soil conditions, or infrastructure (Roads) can have a direct impact on the water quality, specifically the turbidity of local water. The quantitative measure of sediment with water is known as Total Suspended Sediment, and can be related to other water quality measures such as conductivity. Total suspended solids is determined by filtering a known volume of water and measuring the mass of the suspended material that is captured on a fine filter., Lemke, E., Atkinson, D., Wellen, C.

    Swipe-Technology’s Influence in Born Digital Culture: Redesigning Pedagogy in Early Childhood Education
    Swipe-Technology’s Influence in Born Digital Culture: Redesigning Pedagogy in Early Childhood Education
    This essay examines the ways in which technology defines and divides generations and considers how swipe-­technology (touch-­screen technologies) shape emerging learning styles. Specifically, it focuses on the research currently being investigated on how forms of digital literacy represent a radical shift, away from traditional forms of literacy (Prensky, 2001a, b; Frand, 2000; Prensky, 2001b; Tapscott, 1997; Franco, 2013; Plowman & McPake, 2013; Infante, 2014; Passey, 2014) and evaluates various claims made about the social consequences of such change. This paper emphasizes the impact that swipe-­technology has on young children during early stages of their development and seeks to answer the following question: what are the consequences of digital language becoming the Born Digital’s (Franco, 2013) primary form of expression? The paper draws on some traditional theories such as those of Mannheim (Kecskemeti, 1952) and Vygotsky (1929, 1962, 1978) to provide a broader contextualization. In so doing, it hopes to contribute to the dialogue about how educational institutions should be redesigned to accommodate new media technologies.
