Introduction for Informed Learning Applications: Insights from Research and Practice

Informed learning practice encompasses a range of approaches including collaboration between librarians and classroom instructors (whose primary responsibility is teaching regularly-scheduled courses) to construct connections between informed learning theory, information literacy practice, and disciplinary scholarly products to foster reflective and deep engagement with information. Informed learning differs from other approaches to information literacy in that the focus is on both the process of learning disciplinary content and the knowledge gained as a result of interacting with information (information literacy experiences) while seeking, evaluating, and citing. Reflection, transformation, and relationship are vital elements of informed learning, and scholarly communication is integrated into the process, not simply an end product. As librarians foster informed learning, they expand the relationships between instructors, student learning, and the world of information

Seventh-day Quaker: A spiritual memoir

In an intimate spiritual memoir, Ranger shares her reflections on a journey of self-discovery. Through a narrative written in diary format, she compares and contrasts the Religious Society of Friends and the Seventh-day Adventists and calls for better understanding of and bridges between liberal and conservative Christians. Seventh-day Quaker examines the role and practice of sabbath, silence, prayer, rites and rituals, evangelicalism, the Bible, Creationism, God\u27s existence, and the call to ministry.https://scholarworks.gvsu.edu/rel_books/1000/thumbnail.jp

A molten salt test loop for component and instrumentation testing

Molten salt is an effective coolant for a wide range of applications, including nuclear reactors, concentrated solar power, and other high temperature industrial heat transfer processes. The technical readiness level of components and instrumentation for high-temperature molten salt applications needs improvement for molten salt to be more widely adopted. A molten salt test loop was designed, built, and commissioned as a test bed to address these issues. The molten salt test loop at Abilene Christian University was built out of 316 stainless steel with a forced flow centrifugal-type pump, and was instrumented for remote operation. A low-temperature molten nitrate salt was used in this system, which was designed to operate at temperatures up to 300 ◦C and flow rates up to 90 liters per minute. This paper describes the loop design, computational fluid dynamics modeling, construction, and commissioning details. An outline of the data acquisition and control systems is presented. Salt samples were taken before and after introduction into the loop, and melting points were measured both before and after salt circulation. Performance of the system is discussed as well as improvements required for higher temperature loops envisioned for the future

Photodegradation of the Mycobacterium ulcerans Toxin, Mycolactones: Considerations for Handling and Storage

Background: Mycolactones are toxins secreted by M. ulcerans, the etiological agent of Buruli ulcer. These toxins, which are the main virulence factors of the bacilli, are responsible for skin lesions. Considering their specificity for M. ulcerans and their presence in skin lesions even at early stages, mycolactones are promising candidates for the development of a diagnostic tool for M. ulcerans infection. Stability of purified mycolactones towards light and heat has not yet been investigated, despite the importance of such parameters in the selection of strategies for a diagnosis tool development. In this context, the effects of UV, light and temperature on mycolactone stability and biological activity were studied. Methodology/Principal Findings: To investigate the effect of these physical parameters, mycolactones were exposed to different wavelengths in several solvents and temperatures. Structural changes and biological activity were monitored. Whilst high temperature had no effect on mycolactones, UV irradiation (UV-A, UV-B and UV-C) and sunlight exposure caused a considerable degradation, as revealed by LC-MS and NMR analysis, correlated with a loss of biological activity. Moreover, effect of UVs on mycolactone caused a photodegradation rather than a phototransformation due to the identification of degradation product. Conclusion/Significance: This study demonstrates the high sensitivity of mycolactones to UVs as such it defines instruction
