    Influence of Stellate Ganglion Stimulation on Morphology of Alveolar Type II Cells

    This research provides ultrastructural information regarding pulmonary surfactant secretion from stimulation of adrenergic pathways to the lung via the stellate ganglion. This information will help clarify the important role of the sympathetic nervous system in surfactant disorders. It also provides insight into sympathetic mechanisms causing surfactant derangement in adult and infant respiratory distress syndromes (RDS). Basic cellular mechanisms of surfactant metabolism, including synthesis and packaging in lamellar bodies, were studied. Results shed light on these basic processes of lung cell function. The results of this study provide new avenues for studying a problem in health care that has long resisted advances, that of surfactant replacement therapy. It is expected that the results of this research, taken with information from other researches, will ultimately reduce the 50% mortality rate of the 150,000 patients annually suffering from RDS (Andreadis and Petty 1985)

    How Newspapers in Kansas Are Using News Releases from K-State Research and Extension

    This study looks at how newspaper editors in Kansas use news releases from Kansas State University Research and Extension (KSRE), which distributes more than 700 news releases annually to newspapers across the state. An analysis of clippings over 10 weeks showed that editors rarely change the original text or headline in KSRE news releases, and more than half of the releases were published within 10 days of release. KSRE news releases were published in all regions of Kansas. Using a formula to determine the advertising equivalency value of news clips, the data indicates a value of $33,286.94 for the sample studied. The findings provide one way in which to report accountability to the organization’s administrators, as well as a better understanding of possible areas of improvement for the KSRE news office

    A worthy goal for educators is the continued search for an understanding of children\u27s learning. Continued research and observation of children in a variety of settings provide educators with theoretical perspectives and methodological applications for classroom instruction

    Flood Mapping of Recent Major Hurricane Events with Synthetic Aperture Radar, Commercial Imaging, and Aerial Observations

    Floodwater mapping is an important remote sensing process that is used for disaster response, recovery, and damage assessment practices. Developing a system to read in Synthetic Aperture Radar (SAR) data and perform land cover classification will allow for the production of near real-time inundation mapping, enabling government and emergency response entities to get a preliminary idea of the situation. SAR is a unique remote sensing tool. Data in this project was obtained by NASA Jet Propulsion Laboratorys Uninhabited Aerial Vehicle SAR (UAVSAR), an L-band radar mounted to a Gulfstream III jet. Data collected by UAVSAR is similar to what will be available from the NASA-Indian Space Research Organization (NISAR) mission starting in early 2022. Using Python and ArcGIS applications, a model was developed using training samples taken from NOAA post-event aerial photography and UAVSAR data gathered in the aftermath of Hurricane Florence in September 2018

    Next generation software environments : principles, problems, and research directions

    Get PDF
    The past decade has seen a burgeoning of research and development in software environments. Conferences have been devoted to the topic of practical environments, journal papers produced, and commercial systems sold. Given all the activity, one might expect a great deal of consensus on issues, approaches, and techniques. This is not the case, however. Indeed, the term "environment" is still used in a variety of conflicting ways. Nevertheless substantial progress has been made and we are at least nearing consensus on many critical issues.The purpose of this paper is to characterize environments, describe several important principles that have emerged in the last decade or so, note current open problems, and describe some approaches to these problems, with particular emphasis on the activities of one large-scale research program, the Arcadia project. Consideration is also given to two related topics: empirical evaluation and technology transition. That is, how can environments and their constituents be evaluated, and how can new developments be moved effectively into the production sector
