    Ready to revamp the way you teach the library catalog and general databases? Learn how to turn the typical lecture session on its head and ensure each class is different from the last. This versatile lesson can easily be sliced and diced into separate lessons. Attendees will be exposed to numerous attention-getting activities and a plan chock full of teaching moments. The combination of game-like activities, exploratory learning, and presentations will generate a buzz amongst your students. During the presentation, attendees may engage with the content by responding to online polls with their personal mobile devices or laptops. All lesson materials will be available to the attendees

    Beyond Classroom Evaluation: Structuring Research for Dissemination

    Get PDF
    Librarians often pursue worthwhile classroom evaluations, yet the results of those evaluations do not always reach beyond the water cooler or an administrator鈥檚 office door. Whether successful or not, our findings can lead to rapid improvement in instructional methods, but only if we share our knowledge. If the thought of disseminating your research is overwhelming, you are not alone. This interactive session will provide you with techniques for parsing the research process to enable dissemination, especially through formal channels. Participants will draft an action plan for an instruction-related research project, including specific tasks, time horizon, and resource allocation. This session welcomes librarians new to the profession and those experienced librarians interested in conducting and publishing research for the first time

    Estudio qu铆mico y microestructural sobre barras de mortero realizadas con m谩rmoles de la provincia de C贸rdoba ensayadas por el m茅todo M-CAMBT

    En un trabajo previo se estudi贸 la potencial reactividad de m谩rmoles de la provincia de C贸rdoba frente a la reacci贸n 谩lcali-carbonato (RAC) utilizando diferentes m茅todos de ensayo (IRAM 1700, ASTM C586, CSA A23.2-26A y M-CAMBT). Si bien todos los agregados se clasificaron como no reactivos, se registraron algunas expansiones, especialmente en el m茅todo M-CAMBT. A fin de determinar las causas de este comportamiento, se realizaron estudios qu铆micos y microestructurales sobre las barras de mortero post ensayo, mediante estereomicroscop铆a, microscop铆a 贸ptica de polarizaci贸n, microscop铆a electr贸nica de barrido (MEB) y microsonda de electrones (ME). A nivel macrosc贸pico las barras no evidenciaron deterioro. En sectores muy localizados se observ贸 el desarrollo de materiales de neoformaci贸n en cavidades y en microfisuras en la pasta y en la interfase agregado-mortero. A nivel microsc贸pico se observ贸 el desarrollo de bordes de reacci贸n en todos los m谩rmoles dolom铆ticos y calco-dolom铆ticos y fisuras rellenas, asociadas principalmente a agregados con cuarzo tensionado. Los estudios de MEB y ME permitieron asociar los bordes de reacci贸n a procesos de dedolomitizaci贸n (en los m谩rmoles dolom铆ticos y calco-dolom铆ticos) sin evidencias de expansi贸n, siendo m谩s acentuado este proceso cuanto mayor es el contenido de dolomita en la roca. Por otro lado, las fisuras rellenas con materiales de neoformaci贸n, se vinculan a procesos asociados a la reacci贸n 谩lcali-s铆lice (RAS), causados por la inestabilidad del cuarzo tensionado contenido en las mismas. Estos estudios apoyan la teor铆a que las expansiones atribuidas a la RAC son una combinaci贸n de procesos de dedolomitizaci贸n no expansivos y expansiones por RAS producto de la s铆lice reactiva contenida en la matriz de las rocas carbon谩ticas

    The role of stereotactic body radiation therapy in oligometastatic colorectal cancer

    Rationale: Regorafenib is the new standard third-line therapy in metastatic colorectal cancer (mCRC). However, the reported 1-year overall survival rate does not exceed 25%. Patient concerns: A 55-year-old man affected by mCRC, treated with regorafenib combined with stereotactic body radiotherapy (SBRT), showing a durable response. Interventions: After 6 months of regorafenib, a PET/CT scan revealed a focal uptake in a solid lung nodule which was treated with SBRT, whereas continuing regorafenib administration. Fourteen months later, the patient had further progression in a parasternal lymph node, but treatment with regorafenib was continued. The regorafenib-associated side effects, such us the hand-foot syndrome, were favorable managed by reducing the dose from 160 to 120 mg/day. Outcomes: Patient-reported outcome was characterized by a progression-free survival of approximately 3 years. Lessons: in presence of oligometastatic progression, a local SBRT while retaining the same systemic therapy may be a better multidisciplinary approach. Moreover, disease progression is no longer an absolute contraindication for continuing the regorafenib treatment
