Show moreA water-containing region at or near the surface of the earth, such as a landfill, that is contaminated with hazardous materials is decontaminated by heating the region with bound radio frequency energy from a bound-wave transmission line excitor array disposed outside the region to a temperature to boil water and thereby increase the permeability of the region. The heating is continued by dielectric heating after water has boiled from at least a portion of the region to heat the portion to elevated temperatures substantially above the boiling point of water. The materials may then be rendered innocuous in situ in a number of ways, as by pyrolysis, thermally assisted decomposition, or reaction with an introduced reagent, such as oxygen. The materials may also be driven from the region, as by distillation or by evaporation and steam drive and then collected and disposed of, as by incineration.

Show moreThe use of solar chimneys to improve natural ventilation in buildings has been shown to yield energy savings while maintaining thermal comfort in some climate zones. However, one disadvantage is that the ability to control passive ventilation with solar chimneys is often limited by temporal variations of building function and diurnal weather patterns. The unique thermal properties of phase change materials (PCMs) may provide opportunities to manage some of the limitations of solar chimney strategies in buildings through the timed storage and release of thermal energy, which can aid in minimizing daytime heat gains and increasing the effectiveness of nighttime flushing by natural ventilation. This work explores the potential of PCMs combined with solar chimneys to support the passive ventilation of buildings using whole building energy simulation. Results are intended to inform architects and engineers on best practices for incorporating PCMs in buildings with solar chimneys. A model of a prototype office building designed to ASHRAE Standard 90.1 was developed in EnergyPlus and investigated in five U.S. climate zones. A total of 1023 energy simulations were performed to address the following research questions: (1) In what U.S. climate zone is the use of PCMs most appropriate? (2) Can PCMs improve night flushing ventilation when used with a solar chimney? (3) What are the optimal locations for installation of PCMs in building and solar chimney construction in order to provide optimal cooling load reductions? and (4) How do PCM properties influence cooling load reductions? Results demonstrate that the solidification and melting process of PCMs can indeed be used to prolong natural ventilation for night flushing in the evening and nighttime, particularly in climate zones with large diurnal outdoor temperature fluctuations. Results also suggest the following: (1) the optimal location for installation of PCMs in most climates is within the structure of south-facing envelope assemblies; (2) the PCM melting temperature should be equal to or greater than the zone set point temperature; (3) thicker PCMs can yield slightly more cooling energy savings than thinner PCMs; and (4) the thermal conductivity of PCMs does not appear to have a substantial influence on performance.

Show moreThe Chinese Dream is President Xi Jinping's integrative and transformative vision for China, with the goals to achieve "a great rejuvenation of the Chinese nation". However, the realities in China seem to be far from the conditions of a dream. The emerging Chinese middle class are eager to join the army of slaves to their impossible mortgages for their bedroom town homes, in fulfillment of what the modern Chinese psychodynamics have collectively decided to be a necessity in pursuance of a good life. So, where are the capacities of the Chinese Dream for the individuals in this modern times? The dream has to address the deteriorating sense of belonging and home of the millions of working middle class, before it can even consider itself a collective effort. The individuals should be encouraged to dream and strive, in order for this to happen, the fundamentals of a good living environment must be collectively accessible. Studies on the collective forms of housing in China's recent history had shed light onto the importance of urban elements such as the hutong network and socialist work unit in social control. However, a case study on China's gated housing models had also opened up discussions on what a complete razing of culture, history and forced resettlements had done in the name of providing quantities of housing within China's neoliberal shift. This thesis explores the elements of providing quality living environments for this group of people that have been called upward-mobile, tech-savvy and entrepreneurial. With the idea of owning a house becoming increasingly important to the Chinese middle class, architecture attempts to bridge gaps between the realities of the sub-par housing towers in gated peripheral areas and the dying traditions of collectivism. By looking at the success of the hutong and danwei dormitories as spaces for social order as well as spaces for commercial and social interaction, a translation of this is deemed to be emulated in modern housing. A super-hybrid of dwellings and designed "programmatic infection" is bound to happen by studying the development of "dream-like" housing prototypes in history.

Show moreThis dissertation studies the problem of approximating functions of d variables in a separable Banach space Fd. In particular we are interested in convergence and tractability results in the worst case setting and in the average case setting. The symmetric positive definite kernel in both settings is of a product form Kd(x, t) := d =1 1 − α2 + α2 Kγ (x , t ) for all x, t ∈ Rd. The kernel Kd generalizes the anisotropic Gaussian kernel, whose tractability properties have been established in the literature. For a fixed d, we study rates of convergence, which indicate how quickly approximation errors decay. Since rates of convergence can deteriorate quickly as d increases, it is desirable to have dimension-independent convergence rates, which corresponds to the concept of strong polynomial tractability. We present sufficient conditions on {α }∞ =1 and {γ }∞ =1 under which strong polynomial tractability holds for function approximation problems in Fd. Numerical examples are presented to support the theory and guaranteed automatic algorithms are provided to solve the function approximation problem in a straightforward and efficient way. viii

Show moreEnthusiasts propose that social media promotes vertical political communication, giving citizens the opportunity to interact directly with their representatives. However, skeptics claim that politicians avoid direct engagement with constituents, using technology to present a façade of interactivity instead. This study explores if and how elected officials in three regions of the world are using Twitter to interact with the public. We examine the Twitter activity of 15 officials over a period of six months. We show that in addition to the structural features of Twitter that are designed to promote interaction, officials rely on language to foster or to avoid engagement. It also provides yet more evidence that the existence of interactive features does not guarantee interactivity.

Show morePedicularis rex is a hemiparasitic plant from the Orobanchaceae family. Hemiparasites, also called semiparasites, are partly dependent on their host and, while they steal nutrients and other metabolites like other parasites, they have retained their photosynthesis ability. To better understand the hemiparasitic lifestyle of Pedicularis rex and what remains of its photosynthetic capability, we have determined the complete sequence of its plastid chromosome. The chloroplast genome of Pedicularis rex is 153,650 base pairs-long and exhibits a typical quadripartite structure with a large single copy (LSC) region and a small single copy (SSC) region separated by two inverted repeats (IR). A total of 79 unique protein-coding genes, including 9 pseudogenes, 30 tRNA- and 4 rRNA-encoding genes were retained in the plastid genome. Compared to the plastome of its close non-parasitic relative Lindenbergia philippensis, only one protein-coding gene and one intron are missing from P. rex but many genes show signs of pseudogenization. Pseudogenization in the P. rex plastid genome was found to be mainly caused by single site insertions, deletions or substitutions. The overall high level of homology between the P. rex and L. philippensis plastomes may explain why P. rex shows weak host dependence. However, how P. rex maintains its photosynthetic capability despite featuring a number of potentially dysfunctional pseudogenes involved in photosynthesis is unclear, and the minimal set of genes that is required for hemiparasitic plants to keep their autotrophic lifestyle is still unknown.

Show moreThe current trend of increased consumption of fresh produce has coincided with an increase in foodborne illness resulting from fresh produce consumption, which in turn has increased the amount of research directed at understanding the interactions between microbial pathogens and fresh produce. This dissertation examines the removal and inactivation of Escherichia coli O157:H7 and E. coli K12 from Romaine lettuce leaves and a model hydrophobic surface (polyvinyl chloride, PVC) using a nanofluid (a fluid containing nanometer-sized particles - in this case, sodium dodecyl sulfate, SDS) and its combinations with organic acids. A novel mechanism previously proposed by Wasan and Nikolov (D. T. Wasan & Nikolov, 2003) was used as the basis to explore the removal of bacteria from these surfaces by the aqueous dispersion of SDS micelles, and to explain how SDS plus levulinic acid at pH<3 improves inactivation of these bacteria. Examination of the bactericidal effect of levulinic acid, SDS, and their combination on E. coli O157:H7 attached to Romaine lettuce leaves revealed that using levulinic acid or SDS alone cannot effectively wash the bacterial cells from the surface or cause inactivation. However, combining them increased the effectiveness of the solution. The most effective combination of SDS plus acid for bacteria removal and inactivation among those we tested was found to be 0.06 mol/L SDS + 0.25 mol/L levulinic acid. This combination, which has a pH of 2.9, inactivated more than 5.2-log E. coli O157:H7 on a leaf surface, and similar results were achieved for E. coli K12 on a leaf surface, and for both E. coli O157:H7 and E. coli K12 on the surface of PVC. Surface and interface measurements, including x surface tension and contact angle, of washing solutions indicated that solutions containing SDS had a lower work of adhesion than those without the surfactant, which shows that a significant role of SDS in the inactivation mechanism is a weakening of the forces of attraction between the bacteria and the surface being cleaned. Our experiments also confirm that SDS likely plays a secondary role which depends on the solution pH. When the presence of an organic acid lowers the pH of the washing solution to below 2.6, the surface charge of E. coli O157:H7 changes from negative to positive (the pH is lower than the bacteria’s isoelectric point). In this case, we hypothesize that negatively-charged SDS molecules attach to the cells’ surfaces and inactivate the bacteria. This work provides additional insight into the complex nature of bacterial detachment from solid surfaces. Our work with aqueous dispersions of SDS micelles indicates how and why bacterial inactivation is increased through a combination treatment of SDS and an organic acid.
