This study explored the mentoring experiences of doctoral students in science, technology, engineering, and mathematics (STEM) doctoral degree programs at Northwestern University. Research suggests that mentoring relationships support student success in STEM disciplines, and further, that lack of mentorship may be a barrier for female students. A mixed-methods approach employing...
In the Western classical art music tradition, a high level of music performance is achieved at the intersection of a musician's emotional, cognitive, and physical processes. Expert classical musicians have both an aural imagining of the sound they intend to produce and the physical associations of what it feels like...
Perhaps better suited for the mosh pit than the orchestra pit, David Lang’s 1991 tour-de-force for solo bass clarinet, Press Release, is a minimalist marvel. Comprised of seven “groove sections” that evolve in seemingly unpredictable ways, Lang cleverly employs monophony to tell a robust story of motivic and harmonic development....
A longstanding goal of synthetic biology has been the programmable control of cellular functions. Central to this is the creation of versatile regulatory toolsets that allow for programmable control of gene expression. Of the many regulatory molecules available, RNA regulators offer the intriguing possibility of de novo design – allowing...
A study is conducted to determine the effects on the early hydration kinetics and
compressive strength by seeding of Portland cement and alkali-activated blast furnace
slag with a pure form of calcium silicate hydrate (C-S-H). The effects of C-S-H seeding
during the early nucleation and growth period of each type...
The Avalon Media System (Avalon) provides access and management for digital audio and video collections in libraries and archives. The open source project is led by the libraries of Indiana University Bloomington and Northwestern University and is funded in part by grants from The Andrew W. Mellon Foundation and Institute...
In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection
method and the microstructure in cement-based material is investigated. Three cement pastes
(Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25
°C were examined. The ultrasonic shear wave reflection...
