    The function of pedestrian-oriented open space in Knoxville\u27s central business district

    Man is constantly affected by his physical environment. Pro-viding pleasant physical elements in open spaces—such as parks, squares, plazas, small green spaces, and sidewalks--helps to produce a better environment in densely developed urban areas. The purpose of this study is to find how the existing open spaces in Knoxville\u27s central business district function by surveying their characteristics of continuity, direction, orientation, center, linkage, enclosure, interruption, circulation, and sequence. A check-list was made to make sure that each site was inspected under the same terms. The data which was obtained by observing the physical items under each characteristic is shown in figures and tables, which indicate the overall condition of a certain survey item. The analysis of the data indicate the strengths and weaknesses of each open space. The result--a description of the character of the whole system of pedestrian open spaces—showed that many marginally functional open spaces break the continuity of open spaces which function well and complement Knoxville\u27s central business district. These findings indicate which places need to be improved the most. Open spaces on Hill Avenue, Main Avenue, Summit Hill Drive, Wall Avenue, Market Square, and Market Street were found to have a relatively pleasant pedestrian environment

    Four health science librarians’ experiences: How they responded to the COVID-19 pandemic crisis

    Get PDF
    In this article, four health sciences librarians from four academic libraries across the country will share their personal or library experiences in reaching out to faculty and students to meet their needs through their initiatives and continuous efforts using various technologies and tools. Three of the four academic libraries are located in two COVID-19 hard-hit states, Michigan and New Jersey. The article will describe their practice of health sciences librarianship during the unprecedented time and provide examples demonstrating how each of them strives to stay relevant, proactive, and become integral to their institutional efforts in support of students and employees working remotely. These examples showcase their efforts in four main areas of library core functions: references/consultation services, library instruction, research support, and resource

    Effects of MWNT nanofillers on structures and properties of PVA electrospun nanofibres

    In this study, we have electrospun poly(vinyl alcohol)(PVA) nanofibres and PVA composite nanofibres containing multi-wall carbon nanotubes (MWNTs) (4.5 wt%), and examined the effect of the carbon nanotubes and the PVA morphology change induced by post-spinning treatments on the tensile properties, surface hydrophilicity and thermal stability of the nanofibres. Through differential scanning calorimetry (DSC) and wide-angle x-ray diffraction (WAXD) characterizations, we have observed that the presence of the carbon nanotubes nucleated crystallization of PVA in the MWNTs/PVA composite nanofibres, and hence considerably improved the fibre tensile strength. Also, the presence of carbon nanotubes in PVA reduced the fibre diameter and the surface hydrophilicity of the nanofibre mat. The MWNTs/PVA composite nanofibres and the neat PVA nanofibres responded differently to post-spinning treatments, such as soaking in methanol and crosslinking with glutaric dialdehyde, with the purpose of increasing PVA crystallinity and establishing a crosslinked PVA network, respectively. The presence of carbon nanotubes reduced the PVA crystallization rate during the methanol treatment, but prevented the decrease of crystallinity induced by the crosslinking reaction. In comparison with the crosslinking reaction, the methanol treatment resulted in better improvement in the fibre tensile strength and less reduction in the tensile strain. In addition, the presence of carbon nanotubes reduced the onset decomposition temperature of the composite nanofibres, but stabilized the thermal degradation for the post-spinning treated nanofibres. The MWNTs/PVA composite nanofibres treated by both methanol and crosslinking reaction gave the largest improvement in the fibre tensile strength, water contact angle and thermal stability
