Compilation of architectural drawings documenting planned construction and renovations for Willis Library as of May 2018. The first page includes an index to the rest of the schematics which outline the various components of the project including demolition and HVAC (heating, ventilation, and air conditioning) work, mechanical piping, electrical and lighting, and fire sprinklers for each of the five floors (lower level and floors one through four). Each sheet includes technical details, schedules, notes, and other relevant technical information for the work.

For decades, urban public schools have been plagued by systemic and structural challenges that continue today. Scholars, policymakers, and the general public have pointed to problems of learning in urban schools and to low expectations for urban students' learning, but little attention has been given to how urban students themselves conceptualize learning. This study sought to fill the void by asking a group of urban students about their views of learning. A phenomenographic approach was employed to examine the qualitatively different ways in which 20 urban elementary fifth-grade students expressed their conceptions of learning and of their learning approaches. Consistent with phenomenography, the study was intended to understand the collective expressions of individuals' conceptions regarding a phenomenon, and emphasis was on the mapping of variation across the conceptions. Semi-structured interviews with open-ended questions, conducted individually, elicited the students' conceptions of the meaning of learning and their learning approaches. In a "search for meaning" approach, analyses were based on students' transcribed responses forming a pool of quotations. These quotations were divided first into "what" and "how" categories—"what" is learning and "how" does learning occur—and then into subcategories. The results were a set of categories organized in a two-level hierarchy. The three …

Elemental carbon (EC), a product of incomplete combustion of fossil fuels and biomass, contributes to climate warming and poor air quality. In urban areas, diesel fuel trucks are the main source of EC emissions from mobile sources. After emission, EC is deposited to receptor surfaces via two main pathways: precipitation (wet deposition) and directly as particles (dry deposition). Urban trees may play an important role in removing EC from the atmosphere by intercepting and delivering it directly to the soil. The goal of this research was to quantify the magnitude of EC retention in leaf waxes (in-wax EC) and EC fluxes to the soil via leaf litterfall in the City of Denton, Texas. Denton is a rapidly growing urban location in the Dallas-Fort Worth metropolitan area. A foliar extraction technique was used to determine EC retention in leaf waxes. Foliar samples were collected monthly, from April through July, from pairs of Quercus stellata (post oak, n=10) and Quercus virginiana (live oak, n = 10) trees. Samples were rinsed with water and chloroform in a two-step process to determine EC retained in leaf waxes. A Sunset OC/EC aerosol analyzer was utilized to analyze the EC content of extracts filtered onto quartz-fiber …
