Description
The process of learning orchestra reductions on the piano is rather different from learning a piece originally written for the piano. Even though Dvořák’s Concerto for Cello and Orchestra in b minor is among the most performed works for cello and orchestra, and has been transcribed carefully by both the composer and other editors, the existing piano reductions are not always representative of many important aspects of the original orchestral score. Some reductions have large portions with unplayable or uncomfortable passages for pianists, or imprecise notations compared to the original orchestration, such as inaccurate indications for dynamics, rhythms, and notes. In rehearsal and performance, the pianist is challenged to adapt and transform one of the existing reductions into a playable and productive piano reduction, one which creates Dvořák’s full orchestral sonorities while retaining clarity of voicing. The resulting sound can be infinite in variety, as individual decisions and reductions may differ greatly. This paper will explore the following: how to reduce this orchestral score and solve the technical problem involved in orchestral writing for piano while effectively producing the sound of the orchestra in the piano reduction. There will be a literature review on important published reductions and a brief history of the work and composer. While it is not possible to discuss in detail each passage that has been revised or altered, this paper will focus on and analyze representative and substantial passages, including the perspective of two different reductions: Bärenreiter (2011) and Bärenreiter Praha (2004). It will provide a detailed demonstration of each example and will make suggestions for changes which will concentrate on capturing the essence of the orchestral score at the piano. Chapter one introduces and presents current editions. Chapters two, three and four will discuss each movement of the concerto with detailed explanations about changes in certain passages and sections. The appendix will feature a new revised reduction of Dvořák’s Cello concerto in B minor.

Description
Mobile sources emit a number of different gases including nitrogen oxides (NOx) and volatile organic compounds (VOCs) as well as particulate matter (PM10, PM2.5). As a result, mobile sources are major contributors to urban air pollution and can be the dominant source of some local air pollution problems. In general, mobile sources are divided into two categories: on-road mobile sources and non-road mobile sources. In Maricopa County, the Maricopa County Air Quality Department prepares inventories of all local sources [11], [12]. These inventories report that for Maricopa County, on-road mobile sources emit about 23% of total PM2.5 annually, 58% of the total NOx, and 8% of the total VOCs. To understand how future changes how vehicles might impact local air quality, this work focuses on comparing current inventories of PM2.5, black carbon (BC), NOx, and VOCs to what may be expected emissions in future years based on different scenarios of penetration of hybrid gas-electric vehicles (HEV) and electric vehicles (EV) as well as continued reduction in emissions from conventional internal combustion (IC) vehicles. A range of scenarios has been developed as part of this thesis based on literature reports [6], [8], air quality improvement plan documentation [5], projected vehicle sales and registration [3], [4], as well as using EPA’s Motor Vehicle Emission Simulator (MOVES) [9]. Thus, these created scenarios can be used to evaluate what factors will make the most significant difference in improving local air quality through reduced emissions of PM2.5, BC, NOx and VOCs in the future. Specifically, the impact of a greater fraction of cleaner alternative vehicles such as hybrid-electric and electric vehicles will be compared to the impact of continual reductions in emissions from traditional internal combustion vehicles to reducing urban air pollution emissions in Maricopa County.
