Drawing on criminological history, visual studies, modernist scholarship, sociological treatises, and theories of archives and collection, this study proposes that literary texts of the early twentieth century approached the problem of knowing and representing others through collections. Inspired by the supposed divide between the city and the small town, modernist writers depict—but also resist—a vision of the group and the individual as inscrutable. The criminological apparatus of the turn of the century attends to both urban and provincial modes of existence, promising the small circles, close study of individuals, and knowability of the small town while also acceding to the urban vision of people in vast unknowable quantities and a perpetual psychic distance from others. Criminology was positioned, and positioned itself, as decidedly modern in its data-driven approach to managing the presumed unknowability of the individual and the group. The texts in this study continually grapple with accessing individual identity amidst the masses of modern humanity, and articulate this struggle through representation of small groups, circles, and coteries. It is through the enclosed set of people that Sherwood Anderson, Gertrude Stein, and Carl Van Vechten demonstrate a fixation on both the individual and the group, and the relationship between the two. Their literary output and personal associations—which center on observation, portraiture, and collection—are fundamentally criminological in their efforts to negotiate the distance and intimacy of modern life.

In the bio/pharmaceutical industry, fermentation is extremely important in pharmaceutical development, and in microbial research. However, new fermentor designs are needed to improve production and reduce costs of complex systems such as cultivation of mammalian cells and genetically engineered micro-organisms. Traditionally, stirred tank design is driven by the oxygen transfer capability needed to achieve cell growth. However, design methodologies available for stirred tank fermentors are insufficient and many times contain errors. The aim of this research is to improve the design of production scale stirred tank fermentors through the development of dimensionless correlations and by providing information on aspects of fermentor tanks that can aid in oxygen mass transfer. This was accomplished through four key areas. Empirical studies were used to quantify the mass transfer capabilities of several different reactors. Computational fluid dynamics (CFD) was used to assess the impact of certain baffle and impeller geometries. Correction schemes were developed and applied to the experimental data. Dimensionless correlations were created from corrected experimental data to act as a guide for future production scale fermentor design. The methods for correcting experimental data developed in this research have proven to be accurate and useful. Furthermore, the correlations found from the corrected experimental data in this study are of great benefit in the design of production scale stirred tank fermentors. However, when designing a stirred tank fermentor of a different size, further experimentation should be performed to refine the correlations presented.

Chemical looping combustion (CLC) is a promising fossil fuel combustion technology, which is able to separate CO2 from the flue gases without a large consumption of energy. In this thesis, the study was extended to look at the use of chemical looping materials within traditional fluidised bed combustion and investigation of the interaction between the fuel, the supplied air and the chemical looping agent. Three topics of chemical looping combustion are discussed, including 1) the Sherwood number in the fluidised bed; 2) properties of different oxygen carriers, Fe2O3 and CuO (with supporting materials), were tested in the fluidised bed reactor; 3) the simulation of a steady state and a dynamic model of a coal-fired CLC power plant using Fe2O3 as oxygen carriers. The Sherwood number, which represents the mass transfer rate, is important in the calculation of CLC process. With Sherwood number, the mass transfer rate kg around the acting particle can be calculated using correlation Sh=kg∙d/D, where d is the diameter of acting particle, and D is the diffusivity around the acting particle. Hayhurst and Parmar (Hayhurst and Parmar 2002) calculated the Sherwood number in the fluidised bed by using the CO/CO2 ratio, which was measured by the temperature difference between the carbon particle and the bulk phase (Hayhurst and Parmar 1998). However, the temperature of the particle could be overestimated, so the CO/CO2 ratio could be underestimated. In this thesis, a universal exhaust gas oxygen (UEGO) sensor was employed, which could measure the actual carbon consumption rate in the fluidised bed by oxidizing CO in the sample gas into CO2 and. Fe particles of the same size of the char particle is used to measure the O2 consumption rate, and thus eliminate uncertainty in the Sherwood number. The CO/CO2 ratio was calculated by using the carbon consumption rate and the O2 consumption rate. In contrast to Hayhurst and Parmar (Hayhurst and Parmar 2002) who assumed CO2 was the main product, for this char the actual ratio of CO/CO2 was almost zero. The measurement here is in agreement with Arthur. This more accurate determination of CO/CO2 allows a better estimate of the mass transfer coefficient and leads to a correction of the Hayhurst and Parmar’s (Hayhurst and Parmar 2002) correlation by a factor of 1⁄2. Interestingly, very small fluidised beds have mass transfer coefficients which are about twice that expected in a large bed (owing to the very different flow and indeterminate flow pattern). This means the correlation of Hayhurst and Parmar (Hayhurst and Parmar 2002), by fortuitous coincidence works wells for beds with diameters < 30 mm., without the correction factor, should be ignored. In the fluidised bed in a typical CLC process, different fluidising material could have different influence on the reactions. Thus, it is worth discussing different kinds of fluidising materials. The char combustion in the fluidised bed was simulated by using inert (sand) and active (Fe2O3 or CuO) fluidising materials, and air as fluidising gas. The results indicated that 1) CO combustion in the boundary layer leads to smaller carbon consumption rate and larger oxygen consumption rate; 2) Using Fe2O3 particles as fluidising materials slows down the carbon consumption rate, since the diffusivity of CO2 is smaller than CO; 3) CuO particles slow down the carbon consumption rate at large Sherwood number (Sh=2 or 2.5). The influence of using CuO as fluidising material is further discussed experimentally by using low O2 fluidising gas. The results indicated that since the amount of CuO used in the experiment is small, when the O2 concentration in the bulk phase is lower than the equilibrium concentration, the O2 concentration in the bulk phase gradually decreases, and the O2 concentration in the bulk phase has large influence on the char particle combustion. A steady state model of a coal-fired CLC power plant was simulated. The aim of the model was to test the suitable operating conditions of the power plant, such as recycle rate of oxygen carriers, for the power plant design. In the steady state model, the power plant consists of a combustor and a steam cycle. Hambach lignite coal, Polish bituminous coal and natural gas were tested as fuels. The results indicated that: (1) The effect of the fuel is largely due to the amount of oxygen required per GJ released; (2) Preheating is important, but seems to have a minor effect since the most of the heat is released at temperatures well above the pinch point; (3) since the temperatures of heat source in this research is well above the pinch point, all heat are usable for the steam cycle. In this case, the steam cycle and the chemical looping plant could be optimised separately; (4) As long as the preheat temperature of the air flow into the air reactor is higher than the temperature of turbines, in most of cases the power output is unaffected by the choice of variables, leaving the designer free to choose the most convenient. With the conclusions above, a dynamic model of a coal-fired CLC power plant using Fe2O3 as oxygen carrier is then simulated. The aims of this simulation include: 1) explaining the kinetics of Fe2O3 oxygen carriers at high temperature (1223K) in a fluidised bed reactor using Brown’s data (Brown 2010); 2) a 1GWth dynamic power plant was simulated to test different cases including changing power supply and power storage. In the dynamic model, a chemical looping power plant using Hambach lignite char is tested, and the parameters of the system are adjusted so as to simulate the operations of a real chemical looping power plant. The two-phase model is employed for the fluidised bed reactors. Experimental data from Brown (Brown 2010) was simulated using this model first to test its validity. Then the model is scaled up to simulate a 1GWth dynamic power plant. The ideal operation conditions are found, and a char stripper is found helpful for carbon capture.

This study explores the nature and extent of Sherwood Anderson's influence upon William Faulkner. It demonstrates, through the use of the comparative method, that Anderson's influence is a major and continuous one. The early New Orlean Sketches strongly echo and, at times, imitate Anderson's work. Faulkner's first novel, Soldiers' Pay, was not only written at Anderson's suggestion but also published through his influence. In Mosquitoes, Faulkner closely modeled his main character after Anderson. Anderson helped Faulkner to organize some of the "folk" material in that novel. Faulkner's early use of negro characters to embody a kind of sane, healthy alternative to the world of the whites may well have been encouraged by Anderson's example. Furthermore, Anderson played an important role, at a crucial period In Faulkner's development, in directing him to the fictional use of the Yoknapatawpha material. He led Faulkner to realize that universality in art could grow out of regional material. Faulkner's sense of community and his exploration of the individual's search for community so closely resemble Anderson's as to suggest some indebtedness. Faulkner's dramatization of the effects of the destruction of that community by the forces of modern commerce and industry is rendered in terms similar to Anderson's. Also, Faulkner's creation of an idyllic, rural world in contrast to the mechanistic, urban world resembles that in Anderson's stories of horses and men. And Faulkner uses Anderson's idea that the world of horses is a totally male world elsewhere in his fiction. There is a strong resemblance, finally, in Faulkner's and Anderson's concept of the grotesque: for both, it concerns truth and its consequences in the individual's Isolation and behaviour. In fact, it is argued that Anderson's "theory of the grotesque" provides a rationale for the larger structure of some of Faulkner's most important work. For these reasons, it is concluded that Anderson was an important force in shaping the form and content of Faulkner's art. / Arts, Faculty of / English, Department of / Graduate
