Effect Of Concentration And Ph On Parametric Pumping Separations, Tsu-Kun S. Hsieh

Theses

The technique of parametric pumping represents a new and valuable development in the separation science of proteins. Many conventional protein separation are often processed batchwise. However, parametric pumping offers the possibility of continuous processing; the continuous process provides both the advantages of decreasing the processing time and of minimizing degradation.

Preliminary step testing experiments were conducted to study the equilibrium of protein between the stationary and mobile phase of the sephadex ion exchanger.

It was the purpose of this research to study the feasibility of operating a semi-continuous parametric pump with a sephadex ion exchanger for the separation of a …

Increasing interest is being shown in anaerobic digestion as a process for both waste treatment and energy production. In this paper an experimental procedure for investigation of anaerobic digestion of livestock wastes is described, and data from experimental work is presented and analyzed. A model of anaerobic digestion is developed which includes conversion of soluble COD to volatile suspended solids by growth of microorganisms and solubilization of volatile suspended solids to soluble COD by enzymes. This model is used for the analysis of the experimental data.

The Solar Connection -- Promise Or Peril?, Paul S. Strong

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

During the past decade important progress has been made in understanding the sun-earth environmental system. Modern observations of solar activity document changes in solar output over time scales ranging from seconds to decades, and evidence for longer term variations have been found in historical records. It follows that the sun cannot be considered to be a totally non-variable energy source. Continued research progress into solar-terrestrial interactions will hopefully provide an understanding of sun-weather/climate relationships resulting in energy conservation through more efficient energy utilization of our planet's atmospheric energy system.

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr^-1. The optimum rate of …

Concentrated Organic Separations By The Cyclic Indirect Freezing Process, Jeffrey Carl Miles

Chemical and Biological Engineering ETDs

This study demonstrates the technical feasibility of purifying concentrated organic solutions by the cyclic indirect freezing process with in-situ washing and in-situ melting operations. The key to a successful purification in the freezing process is a near plug flow displacement of unfrozen liquor from the bed in an in-situ washing operation. To be successful, a freezing step has to be initiated uniformly and a high permeability bed has to be formed uniformly throughout the freezing conduits. In the study, a nucleation technique based on pressure induced supersaturation has been used to accomplish a uniform initiation and a pressure induced freezing …

Ocean Thermal Energy Conversion By Using A Solidification Melting Cycle, Wen Liang Lin

Chemical and Biological Engineering ETDs

An OTEC (Ocean Thermal Energy Conversion) power plant uses warm surface seawater (24° C - 28° C) as a heat source and deep cold seawater (4° C - 7°C) as a heat sink. With this temperature difference, a heat engine which delivers either mechanical or electric power can be con­structed. There are some limitations and problems of evaporators and condensers to be used in a closed Rankine cycle OTEC plant which have seriously limited the applicability of this concept. This study proposed a process using the S/L engine---a heat engine that utilizes a working medium undergoing solidification and melting operations. …

Micro-Relief Surface Depression Storage: Changes During Rainfall Events And Their Application To Rainfall-Runoff Models, J. Kent Mitchell, Benjamin A. Jones Jr.

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Micro-relief surface depression storage is one of the dynamic components of the rainfall-runoff process. The quantification of the effect of rainfall intensity and duration on the micro-relief was the subject of this study. Micro-relief measurements were made on 88 soil bin samples before and after the application of simulated rainfall events. The surface depression changes are described with empirical equations, using basic rainfall, surface hydrology, and soil parameters and their cross products as independent variables. A rainfall-runoff model demonstrates the value of a dynamic description of the surface depression storage function.

Fuzzy Probability And Probabilistic Processes, Abraham Kandel

Electrical and Computer Engineering ETDs

In this dissertation, contributions to fuzzy probability and to differential equations with fuzzy parameters are made.

After an introductory chapter, a review of fuzzy sets and fuzzy algebra is given in Chapter 2. The main new results of the dissertation are contained in Chapter 3.

In Chapter 3, Zadeh's definition of the probability of a "fuzzy event" and "the event" and "the average value of a fuzzy function" are extended into the time domain. It is then shown that not only grades of membership, but also probabilistic processes with notions of fuzziness contained, can be defined which obey ordinary, matric, …

The Fracture Toughness Of Steel-Aluminum Deformation Welds, Charles Ellis Albright Jr

Chemical and Biological Engineering ETDs

A study of the fracture toughness (in this case, Gic) of steel-aluminum deformation welds using a specially developed double cantilever beam fracture toughness specimen is presented. Welds made at 350C were heat treated at 360, 380, 400, 420 and 440 C.

An intermetallic reaction product layer of Fe2Al5 is formed at the steel-aluminum interface with increasing heat treating temperature and time by a process of nucleation and growth of discrete particles. A transition in toughness from a higher average Gic value (6097 N/m) to a very low average Gic value (525 N/m) is observed. The decrease in toughness is accomplished …

Sizing Of Liquid Manure Tank Wagons And The Economic Evaluation Of Liquid Manure Injection, J.N. Scarborough, Elbert C. Dickey, D. H. Vanderholm

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Liquid manure tank wagons were evaluated on a cost basis to determine the optimum size for a given livestock operation. Also the economics of adding a liquid injector to the tank wagon was studied for profitability.

INTRODUCTION

The proper selection of a liquid manure tank wagon is a problem faced by many progressive livestock producers with liquid manure systems. Selection of a manure tank wagon is usually based on the farmer's or dealer's opinion of what size is right rather than on a logical analysis including an economic analysis of the costs involved. This paper provides guidelines for selecting the …
