Cntr Design And Proof Of Concept For Liquid Metal Rotating Fuel Tubes, Catherine Carver, Caroline Dowling, Miguel Alessandro Lopez, Ben Rosenberg, Dan White

Mechanical Engineering Capstone Design Projects

Modern chemical engine technology is insufficient to fulfill humanity's aspiration to explore deep space. The 900 s Isp that Nuclear Thermal Propulsion (NTP) engines can achieve is sufficient to enable missions like manned missions to Mars. When employing a storable propellant like hydrogen, methane, ammonia, etc., extravagant missions like this call for a specific impulse of at least 900s to be successful. Consequently, High-Performance Nuclear Thermal Propulsion (HP-NTP) is necessary for space travel for it to take an acceptable length of time. A human voyage to Mars that lasts less than 15 months will be possible thanks to HP-capacity NTP's …

Dietary Marine-Derived Ingredients For Stimulating Hair Cell Cycle, Aleksandra Augustyniak, Helena Mcmahon

Natural dynamics of the hair growth process can be impaired by several factors, such as genetic predisposition, hormonal disorders, aging, poor nutrition or stress, which can lead to the slowdown in the growth of hair or even hair loss. The aim of the study was to assess the hair growth promotion effect of marine-derived ingredients, hair …

I Felt Unfettered And Alive: A Musical Narrative Inquiry Into Identity Through Commissioning And Performing New Music For Solo Classical Guitar, Libby Myers

The 21st Century Guitar

This paper discusses how commissioning new music served as a means of musical narrative inquiry into the performance of the authorʼs identity. Traditionally, musicology has centred on the identities of composers; their lives, working practices and philosophies. Meanwhile, the identities of performers have remained inaudible. Challenging this conventional narrative, the commission project foregrounds experiences of identity and subjectivity of the author as performer-researcher. This paper introduces the innovative methodology of musical narrative inquiry used in this project, in which lived narratives of identity are told and re-told in collaboration with the composer to explore what it means to be, or …

Paleotemperature Estimates From Diatom Morphometrics In The Amundsen Sea For Marine Isotope Stage 5, Cesar Lopez

Honors Capstones

Because of ever rising temperatures driven by anthropogenic climate change, much attention has been given to the West Antarctic Ice Sheet (WAIS) by the scientific community. This is due to its sensitivity to global climate change and vulnerability for collapse as evidenced by Pleistocene interglacial events. Paleotemperature estimates from the Amundsen Sea are crucial for understanding how global temperature changes impacted WAIS throughout the Pleistocene. Marine Isotope Stage 5 (MIS 5) is of particular interest as it contains different substages and intervals of fluctuating temperatures. This period also is estimated to have had temperatures equal to, or slightly higher than …

Interlinking Between Income Tax, Citizenship And Democracy? A Case Study Of Canada And China, Jinyan Li

Conference Papers

The interlink between taxation, citizenship and democracy appears to be obvious in Western democracies: citizens are voters, taxpayers and beneficiaries of public spending funded by tax revenues. The literature on the politics of taxation suggests that democratic institutions affect taxation at every stage of the policy-making process, the type of elections and governance model influence the level of redistribution and complexity of the tax system, democracies generally choose policies that are more favorable to the poor than non-democracies, the tax mix varies with the nature of the political regime, and more repressive governments rely less on personal income taxation. Political …

Disaster Risk In The Carceral State, Saptarishi Bandopadhyay, Joshua R. Coene

Articles & Book Chapters

The overlap between prisoner vulnerability and disasters in the United States is undeniable. During 2020 and 2021, the United States endured a series of natural hazards such as wildfires, floods, and hurricanes, many of which exposed the country’s 2.1 million inmates to additional risks and compounded the danger posed by COVID-19. Yet policymakers and scholars are only beginning to appreciate the centrality and magnitude of disaster risk management for the millions of people currently held in penal institutions around the country. Unsurprisingly, the production of “lessons learned” documents that follow in the aftermath of disasters overlook how prisoner vulnerability is …

Pathology Research and Scholarship

Therapeutic plasma exchange (TPE) is a therapeutic intervention that separates plasma from blood cells to remove pathological factors or to replenish deficient factors. The use of TPE is increasing over the last decades. However, despite a good theoretical rationale and biological plausibility for TPE as a therapy for numerous diseases or syndromes associated with critical illness, TPE in the intensive care unit (ICU) setting has not been studied extensively. A group of eighteen experts around the globe from different clinical backgrounds used a modified Delphi method to phrase key research questions related to "TPE in the critically ill patient". These …

Microtunings, Complexity, Variability: A New Sound Map For The Guitar, Pascale Criton, Caroline Delume

The 21st Century Guitar

How do microtunings help broaden the guitar's sound map and bring new musical possibilities? In this contribution, we present a set of works in which the guitar is tuned in the 72 or 96 equal temperament. They are representative of Pascale Critonʼs writing and were composed between 1996 and 2019. Each type of tuning favors its own map of harmonic relations and the generation of specific acoustic behaviors. We examine their structural, technical and expressive peculiarities and highlight how the writing and the instrumental gesture are renewed by these tunings.

Largo Teso: The Seven Studies For Guitar By Maurizio Pisati, Maurizio Pisati, Elena Càsoli

In this contribution, composer and interpreter talk about the Seven Studies from their respective points of view. Maurizio Pisati explains how he developed a new guitar, departing from a single study and arriving at the overall formal conception through timbres, techniques and articulations; and how the soloistic studies led him to a guitarled ensemble piece. Elena Càsoli deals with issues such as the score's indications and the instrumental techniques.

Overlapping Gestural Zones And Modulation On The Fifteen-Tone Guitar, William R. Ayers

The 21st Century Guitar

With its unconventional tuning, notation, and performance requirements, Easley Blackwoodʼs Suite for Guitar in 15- Note Equal Tuning serves as a reappraisal of both tonality (through its application of a microtonal equal temperament) and guitar performance practice (with a modified fretboard and note layout). Using concepts from the fields of transformational theory and gestural music theory, this study considers modulatory and sequential passages in two movements from Blackwoodʼs Suite. This paper demonstrates how the fifteen-tone tuning and fretboard provide a unique opportunity to recontextualize the diatonic scale and its generative interval cycles in a consistent transformational space that allows the …

New Sounds On The Guitar, Agustín Castilla-Ávila

The 21st Century Guitar

The guitar is like an orchestra, claimed Andrés Segovia many times. I completely agree with this statement. I only must add that since Segovia mentioned it last time, the orchestra has quite changed. And so has the guitar. I would like to present my different approaches as a composer to this versatile instrument. I would like to demonstrate some of the new technical resources to obtain new sounds, which I have been exploring and using on the guitar in the last few years. Due to the adaptability of the instrument, I strongly believe that the guitar will take more and …
