    Senescence can play an essential role in modelling and estimation of vector based epidemiological indicators: demographical approach

    Get PDF
    In the paper basic epidemiological indicators, produced by an aging population of vectors, are calculated. In the study we follow two lines: calculations for demographically structured population and individual life-history approach. We discuss the advantages and limitations of these approaches and compare the results of our calculations with epidemiological indicators obtained for non-aging population of vectors.Gibraltar, age effect, disease control, gerontology

    Final Design Review: Design of an Integrated Solar Cell Array to Power a Solar Ear Hearing Aid Battery Recharger

    As the energy of fossil fuel supplies are fast depleting due to high consumptions of energy by human beings, the need for other sources of energy, such as solar energy, has become a viable option. By creating solar cell arrays the desired voltage can be generated. The overall goal of the Solar Ear project is to create an array of photovoltaic cells connected with aluminum tracings to recharge batteries that are specifically used for hearing aids. The goal embodies two main areas: the design of a processing method to connect the cells during a micro-fabrication process and the creation of an array that produces enough voltage and current to power low-power applications like a hearing aid battery recharger. We have successfully designed and fabricated a device with two cells connected in series thus far to make sure the interconnections in our design were capable of connecting cells in an array. An aluminum bridge across an insulating channel of SU-8 was created as an interconnection to connect both cells on the silicon-on-insulator (SOI) wafer. Although we successfully addressed the first goal to connect the cells, this two-cell device did not produce the desired voltage and current. To address this problem we optimized the manufacturing process by creating larger doped regions and forming an oxide over the wafer surface with vias to create the aluminum contacts. These modifications were enacted during spring quarter when we fabricated a 12-cell device. These final devices exhibited good cell interconnection and a maximum of 5.5V was obtained from one of the final wafers. The current produced by these devices, however, was nearly 10 times less than expected and failed to reach the levels necessary to charge a hearing aid battery

    Importance of site of infection and antibiotic selection in the treatment of carbapenem-resistant Pseudomonas aeruginosa sepsis

    ABSTRACT In a retrospective analysis of 215 patients with carbapenem-resistant Pseudomonas aeruginosa sepsis, we observed a significantly higher risk of mortality associated with respiratory tract infection (risk ratio [RR], 1.20; 95% confidence interval [CI], 1.04 to 1.39; P = 0.010) and lower risk with urinary tract infection (RR, 0.80; 95% CI, 0.71 to 0.90; P = 0.004). Aminoglycoside monotherapy was associated with increased mortality, even after adjusting for confounders (adjusted RR, 1.72; 95% CI, 1.03 to 2.85; P = 0.037), consistent across multiple sites of infection. </jats:p

    Hoosiers on the Hardwood: A Critical Examination of Indiana Basketball Culture and its Effect on Identity Formation

    Get PDF
    The purpose of this research was to examine the nexus at which Indiana basketball and the state’s ‘hoosier’ identity meet. More specifically, this thesis interrogates the romanticization of this sporting culture for its pedagogical role in the creation of twenty-first century ‘hoosier’ bodies. Adopting a theoretical orientation rooted in critical race theory, I argue that Indiana’s basketball culture represents a normalized / normalizing structure underneath which Otherness is reified to produce hypervisible “different” outsiders (‘non-hoosiers’), and invisible “disciplined” insiders (i.e. ‘hoosiers’). Utilizing data gleaned over a two-month period spent conducting fieldwork in the “hoosier state” (document analysis, unstructured interviewing, and participant observation), I specifically tailor my analysis to uncover people’s understanding, negotiation, and performance of this regional and national subject position. From this point of inquiry, authentic ‘hoosierness’ comes to be represented, known, practiced, and felt in relation to hierarchies of power that privilege white, hypermasculine, rural, and conservative bodies

    Piloting the Alcohol Feedback, Reflection, and Morning Evaluation (A-FRAME) Program : A Smartphone-delivered Alcohol Intervention

    Get PDF
    Many college students engage in heavy drinking and experience negative consequences, but typically show little motivation to change their drinking behavior. Although personalized feedback interventions (PFIs) show promise, improved effect sizes, engagement, and potential for reach are needed. We developed and pilot-tested a theory-based, smartphone-delivered PFI for heavy-drinking college students that incorporated innovations, including a choice of feedback delivered in multiple doses that occur close in time to drinking events. In an open trial, we delivered the 4-week intervention to 18 heavy-drinking students, followed by individual interviews of participants’ experience. Feasibility was demonstrated by high enrollment and response rates, and acceptability was demonstrated by positive participant ratings and interview responses. Results will inform efforts to continue to develop this novel and scalable mobile intervention for alcohol misuse among college students, with potential impact for the public health problem of high-risk drinking
