Item Convective Heat Transfer in Water-based Alumina Nanofluids(Vanderbilt University. Graduate School, 2009-03-30) Roberts, N. A. (Nicholas A.); Walker, GregNanofluids are solutions of a small fraction of suspended nanoparticles in a bulk fluid. Nanofluids have shown great promise as heat transfer fluids over typically used bulk fluids and fluids with micron sized particles. The nanoparticles do not settle in the fluid and do not cause clogging or damage to surfaces that is seen with micron sized particles. In the current work we compare the performance of different mass loadings of water- based alumina nanofluids in commercially available electronics cooling systems to that of pure water. The commercially available systems is a water block used for liquid cooling of a computational processing unit. The size of the nanoparticles in the study is varied from 10 nm to 150 nm. Results show a moderate enhancement in thermal conductivity and convection heat transfer in the laminar flow regime with increasing mass loading of nanoparticles up to 1% by volume.Item The Effects of "Cloth Politics" in the Trans-Atlantic Slave Trade: Cause, Cash, Commodity and Comfort(Vanderbilt University, 2009-04) Harmer, Crickett; Landers, Jane G.Item Graduate Student Research Symposium 2009 Keynote Address Flier(Vanderbilt University.

At first glance the terms "slavery" and "leisure" may seem to be contradictory, mutually exclusive terms. However, the need to mentally and physically break the bonds of one's circumstances, albeit temporarily, applied equally if not more so to Caribbean and North American slaves of African descent. The creolization of slave leisure activity forms began almost immediately upon their arrival in the Americas, some of which represented a continuation of African traditions while others were adopted from white society. A few forms of leisure even afforded slaves an opportunity to elevate their status relative to that of fellow slaves, compete on an equal footing with whites, and in some instances win their freedom. This paper will examine the creolization of some forms of slave leisure activities from the most easily cross-culturally transportable, to forms that required special apparatuses or venues. It is not intended to be an exhaustive inquiry into all forms of slave leisure. The time period covered will be from the earliest days of the transatlantic slave trade to Emancipation. Finally, there will be some discussion of the impact of slave leisure on North American and Caribbean culture that continues to this day.Item Second Language Acquisition and Teacher Preparation for Teachers of English Language Learners(Vanderbilt University. Graduate School, 2009-03-30) Cole, Mikel; Jimenez, RobertCurrently about 60% of United States classrooms contain ELLs. This powerpoint covers what teachers need to know about language acquisition.Item Singing for Strength: Enslaved Africans and Community Building in the Transatlantic Slave Trade(Vanderbilt University, 2009-04) Moore, J. Hunter; Landers, Jane G.Throughout the Transatlantic slave trade enslaved Africans sang. In holding pens called barracoons awaiting shipment, aboard slave ships crossing the Atlantic, and in the transatlantic colonies, singing was a common feature of daily life and special events. Many people sing, but for enslaved Africans singing may have been a means of survival. Slaves often found themselves surrounded by other slaves with whom they had no prior social relationship. Singing would have enabled them to create an immediate sense of community, mitigating the effects of the severe dislocation they suffered. Singing also helped to preserve a sense of community among slaves once they were settled in the colonies. Contemporary accounts attest to the importance of both singing and community in West Africa, the source for the majority of slaves in the transatlantic trade. Similar evidence exists for African slaves in the British colonies of the Caribbean and North America as well as for their descendants. Finally, a positive view of the creative adaptation or "creolization" of cultural forms by enslaved Africans is compared with earlier analyses that described it as being purely destructive.Item So What are You Going to do with That? Finding Careers Outside Academia(Vanderbilt University, 2009-04-08) Basalla, Susan Elizabeth, 1970-Item Theoretical isosteric heat of adsorption calculation in the Henry's law region for carbon nanopores and nanocavities(Vanderbilt University. Graduate School, 2009-03-30) Liu, Jian; LeVan, M. Douglas, 1949-The isosteric heat of adsorption in the Henry's law region is calculated as a function of the pore width for carbon single wall cylindrical nanopores and spherical nanocavities. The maximum isosteric heat of adsorption is obtained for six gas molecules: argon, methane, carbon dioxide, hydrogen, helium, and nitrogen. In addition, the results for cylindrical carbon nanopores are compared with adsorption data on single-wall carbon nanotubes from the literature. We find the pore width where the isosteric heat of adsorption is a maximum for both geometries. The effect of solid-fluid parameters on the pore diameter for the maximum isosteric heat of adsorption is determined for any system described by a Lennard-Jones potential. Constant relationships between the pore diameters for the maximum isosteric heat of adsorption and the specific solid-fluid parameters are found for cylindrical nanopores, spherical nanocavities, and parallel-wall slit-shaped pores. Surface mean curvature has a significant influence on the isosteric heat of adsorption.
