Fearless: Anastasia Maisel
Working to create a meaningful, respectful, and community-minded Day of Service in honor of Gettysburg College student Emily Silverstein ā11, and continually involved in different farming and food initiatives in the Gettysburg area to promote food justice and environmentally friendly farming practices, Anastasia Maisel ā14 fearlessly gives her time, energy, and passion to promoting social justice on and off campus.

Airloads on bluff bodies, with application to the rotor-induced downloads on tilt-rotor aircraft
The aerodynamic characteristics of airfoils with several flap configurations were studied theoretically and experimentally in environments that simulate a wing immersed in the downwash of a hovering rotor. Special techniques were developed for correcting and validating the wind tunnel data for large blockage effects, and the test results were used to evaluate two modern blockage effects, and the test results were used to evaluate two modern computational aerodynamics codes. The combined computed and measured results show that improved flap and leading-edge configurations can be designed which will achieve large reductions in the downloads of tilt-rotor aircraft, and thereby improve their hover efficiency
Wind-tunnel tests of the XV-15 tilt rotor aircraft
The XV-15 aircraft was tested in the Ames 40 by 80 Foot Wind Tunnel for preliminary evaluation of aerodynamic and aeroelastic characteristics prior to flight. The tests were undertaken to investigate the aircraft performance, stability, control and structural loads for flight modes from helicopter through transition and airplane mode up to the tunnel capability of 170 knots. Results from these tests are presented

Efficient generation of neural stem cell-like cells from adult human bone marrow stromal cells
Clonogenic neural stem cells (NSCs) are self-renewing cells that maintain the capacity to differentiate into brain-specific cell types, and may also replace or repair diseased brain tissue. NSCs can be directly isolated from fetal or adult nervous tissue, or derived from embryonic stem cells. Here, we describe the efficient conversion of human adult bone marrow stromal cells (hMSC) into a neural stem cell-like population (hmNSC, for human marrow-derived NSC-like cells). These cells grow in neurosphere-like structures, express high levels of early neuroectodermal markers, such as the proneural genes NeuroD1, Neurog2, MSl1 as well as otx1 and nestin, but lose the characteristics of mesodermal stromal cells. In the presence of selected growth factors, hmNSCs can be differentiated into the three main neural phenotypes: astroglia, oligodendroglia and neurons. Clonal analysis demonstrates that individual hmNSCs are multipotent and retain the capacity to generate both glia and neurons. Our cell culture system provides a powerful tool for investigating the molecular mechanisms of neural differentiation in adult human NSCs. hmNSCs may therefore ultimately help to treat acute and chronic neurodegenerative diseases
Flute Music of Luigi Zaninelli
Dedication inside front cover of the CD
This recording has been a labour of love and a long journey which has finally come to fruition. It all began with an idea that developed into a doctoral dissertation The Flute Music of Luigi Zaninelli, which has now, many years later, culminated with this CD.

Legal Education at a Crossroads: Innovation, Integration, and Pluralism Required!
We conclude in this Article that expanded practice-based, experiential education will provide foundational learning for the successful transition from law student to law practice, and that clinical education (in-house clinics, hybrid clinics, and externships) is crucial to the preparation of competent, ethical law graduates who are ready to become professionals. We urge law schools to require each graduate complete a minimum of twenty-one experiential course credits over the three years of law school, including at least five credits in law clinics or externships. Twenty-one required credits (or roughly 25 percent of the eighty-three required credits for graduation from an American Bar Association (ABA)-approved law school) would bring legal education closer to, although still below, the experiential and clinical education course requirements of other professions
