Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr Jan 1981

Methane Production From Alkaline Food Waste., Wilson Thomas Gautreaux Jr

LSU Historical Dissertations and Theses

Anaerobic digestion of an alkaline food waste for methane production was investigated. The waste generated by potato processing contained significant quantities of carbohydrate degradation products and sodium carbonate. Anaerobic digestion was determined to be a reliable process for waste treatment and methane production. The high sodium levels did not inhibit anaerobic digestion at a substrate concentration of 1.0 wt % alkaline peel solids. Single and two-stage (separate acid, methane stages) anaerobic digestion systems were studied. In two-stage bench-scale studies at 37(DEGREES)C, methane production averaged 0.28 m('3)/kg COD feed or 0.65 m('3)/(m('3)(.)d) in a settled bacterial sludge methane fermenter with a …

Some Singular Measures On The Circle Which Improve L('P) Spaces., David Lawrence Ritter Jan 1981

Some Singular Measures On The Circle Which Improve L('P) Spaces., David Lawrence Ritter

LSU Historical Dissertations and Theses

Let (mu) be a positive Borel measure on the circle group T. If, for P (GREATERTHEQ) 1, there is a q > p such that (mu) defines a bounded convolution operator from L('p)(T) to L('q)(T), then (mu) is L('p)-improving or (mu) improves L('p). Here a result of Oberlin is extended. It is shown that a large class of Cantor-Lebesgue measures improve L('p)(T) for p > 1. Also, for the members of a particular sequence of Lebesgue measures associated with some homogeneous Cantor sets, which includes the middle-third Cantor-Lebesgue measure studied by Oberlin, estimates are obtained for the amount of improvement. These results …

Faraday Rotation Investigations Of Surface Space-Charge Layers In Metal - Oxide - Semiconductor (Mos) Systems., Gary L. Wallace Jan 1981

Faraday Rotation Investigations Of Surface Space-Charge Layers In Metal - Oxide - Semiconductor (Mos) Systems., Gary L. Wallace

LSU Historical Dissertations and Theses

The free carrier Faraday effect is considered in both the Drude model and the Appel-Overhauser model for inversion layer electrons at the SiO(,2)-Si interface. An exact algebraic relation between the photon, cyclotron, collision and plasma frequencies is obtained which must be satisfied in order to achieve null rotation and null ellipticity for a single pass of the electromagnetic wave in the Drude model. Plots of the rotation versus angular photon frequency in the Appel-Overhauser model for various values of the electron-electron (e-e) scattering time (tau)(,e) are presented. These plots show that Faraday rotation measurements are a possible way of determining …

Frequency Response Analysis Of Distillation Column Interaction., Chien Wang Jan 1981

Frequency Response Analysis Of Distillation Column Interaction., Chien Wang

LSU Historical Dissertations and Theses

A dynamic pressure model of multicomponent distillation is developed in the frequency domain. The model consists of a set of linearized overall and component balances, enthalpy balance, pressure relationship, hydraulic equation and equilibrium relationships for each tray, the condenser and the reboiler of a general column. A numerical method consisting of total scaled pivoting Gaussian elimination with the method of residues is worked out for solving the model in the frequency domain to obtain all of the desired transfer functions. The resulting transfer functions are presented as Bode plots. The measure of interaction between the various control loops can then …

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey Jan 1981

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey

LSU Historical Dissertations and Theses

Linguistic skepticism and the resultant awareness of the limits of language can be traced back to Hamann, Herder, and Humboldt, through Romanticism and French Symbolism, up to modern times. What has come to be called the crisis of language (Sprachkrise) can be viewed as one segment of a broader, multi-media phenomenon. The intensity of this crisis is concentrated in Austro-Hungary in the waning days of the Habsburg Monarchy. From this time forward supersensitivity to language remains a strongly Austrian phenomenon and can be followed through the European, German-language, and Austrian movements of this century, up to the founding of the …

Catalytic Generation Of Hydrogen From The Hydrolysis Of Sodium-Borohydride. Application In A Hydrogen/Oxygen Fuel Cell., Clifford Mark Kaufman

LSU Historical Dissertations and Theses

Hydrogen has been promoted as the energy alternative of the future. Fuel cell utilization of hydrogen minimizes pollution while optimizing energy conversion efficiencies. Sodium borohydride has been investigated as a possible hydrogen storage and transport medium. Within the proper catalytic environment, one gram of sodium borohydride liberates almost 2.4 liters of hydrogen at a controllable rate. The effects of acids, transition metal salts, and transition metals on the hydrolysis of sodium borohydride have been mathematically quantified. Least squares analyses have reduced the data to simple combinations of algebraic expressions. Specifically, acid acceleration is subject to pseudo-first-order kinetics; equivalent acid concentrations …

Theoretical Studies Of Nucleophilic Additions To Alkynes And Stabilities Of Anions., Robert William Strozier Jan 1981

Theoretical Studies Of Nucleophilic Additions To Alkynes And Stabilities Of Anions., Robert William Strozier

LSU Historical Dissertations and Theses

Nucleophilic additions to alkynes were investigated using ab initio molecular orbital theory. Analyses of the energetic consequences of certain molecule distortions showed that the anti selectivity of nucleophilic additions to simple alkyl, aryl, and halogenated alkynes was consistent with trans bending of acetylene. This premise was verified by considering the addition of the hydride ion to acetylene which gave a single transition state resulting from anti addition. Comparing the activation energies for hydride addition to ethylene and acetylene showed that addition to acetylene improves relative to addition to ethylene with increasing basis set sophistication. Nucleophilic addition of ammonia to cyanoacetylene …

Quality Evaluation Of Some Combinations Of Unit Uniform Random Number Generators And Unit Normal Transformation Algorithms., Win-Yeu Winnie Chen Jan 1980

Quality Evaluation Of Some Combinations Of Unit Uniform Random Number Generators And Unit Normal Transformation Algorithms., Win-Yeu Winnie Chen

LSU Historical Dissertations and Theses

Due to the wide applications of normal random variates and the fact that applications are usually affected by their accuracy, an extensive study of the quality evaluation of unit uniform random number generators and unit normal transformation algorithms that are applications specific is recommended. In most simulation applications it is implicitly assumed that if any "good" unit uniform random number generator is used in combination with any "good" transformation algorithm. The resulting random variates will have good properties of randomness and will have the desired fit. The results of this research shows that this assumption is false. Use of good, …

An Externalities Approach To The Analysis Of Federal Grants-In-Aid Emphasizing The Effect Of Grants On Cooperation Among Local Units Of Government., Charles Franklin Hawkins Jan 1980

An Externalities Approach To The Analysis Of Federal Grants-In-Aid Emphasizing The Effect Of Grants On Cooperation Among Local Units Of Government., Charles Franklin Hawkins

LSU Historical Dissertations and Theses

The genesis of federal grants-in-aid can be traced back to the Northwest Ordinances of 1785 and 1787. From those earlier years to the present, grants have been introduced in response to individual needs that have existed at particular points in time. As a result of the basic reaction nature of grants, only a very negligible consideration has been given to developing the individual grants into an integrated, non-conflicting system. As could be expected, the consequence of this approach to grant development has been an uncoordinated grant program containing overlapping grants in some cases and conflicting ones in others. In fact, …
