Experimental Study Of The Fluid Drag On A Torus At Low Reynolds Number., Dharmaratne Amarakoon Jan 1982

Experimental Study Of The Fluid Drag On A Torus At Low Reynolds Number., Dharmaratne Amarakoon

LSU Historical Dissertations and Theses

Measurements are presented for the drag on a torus moving along its axis of rotational symmetry at low Reynolds number. If D is the outside diameter of the torus, and d is the thickness in the axial direction, then the measurements cover the range s(,o) = 1 (the closed torus) to s(,o) = 135, where s(,o) (TBOND) (D/d) - 1. The effect of a coaxial cylindrical boundary (diameter H) is taken into account by an empirical correlation. The values of drag obtained by extrapolating to a fluid of infinite extent are in good agreement with the exact solution obtained by …

The Usefulness And Predictability Of Net Realizable Values: An Empirical Study., Jerry Joseph Baudin Jan 1982

The Usefulness And Predictability Of Net Realizable Values: An Empirical Study., Jerry Joseph Baudin

LSU Historical Dissertations and Theses

The general objective of financial reporting is to provide useful information for making economic decisions. Net realizable value has been recommended and advocated as a valuation method that would improve the usefulness of reported fnancial information. One shortcoming of the net realizable value method is that there are no established used market prices for certain fixed assets, such as buildings. At present, there is no evidence indicating that a solution to this shortcoming has been found. Therefore, the purpose of this study is to empirically test the reliability of using specific price indexes in predicting net realizable values for certain …

A Study Of The Three-Level Hierarchy Of Information Processing In Reading Comprehension With Respect To Cognitive Demand., Lane Roy Gauthier Jan 1982

A Study Of The Three-Level Hierarchy Of Information Processing In Reading Comprehension With Respect To Cognitive Demand., Lane Roy Gauthier

LSU Historical Dissertations and Theses

This study was designed to study the three-level hierarchy of information processing with respect to cognitive demand. The study addressed the problem of differences between the most commonly used levels of comprehension, literal, inferential, and critical. The main types of information processing models, bottom-up, top-down, and interactive-compensatory, all accept the premise that literal processing is less cognitively demanding than inferential processing, and that inferential processing is less cognitively demanding than critical processing. In order to test whether statistically significant differences actually existed in these three levels of comprehension, fifty students were chosen and individually tested. Twenty-five fifth graders, and twenty-five …

Microbial Products From Sweet Potato Wastes., Nhuan Phu Nghiem Jan 1982

Microbial Products From Sweet Potato Wastes., Nhuan Phu Nghiem

LSU Historical Dissertations and Theses

Microbial production of methane from alkaline sweet potato wastes was studied. Assessment of methane production potential was based on total COD of the wastes. A single-stage and a two-stage system were studied. In both systems, to ensure stable operation and high performance, methane fermenters had to be initially seeded with large quantities of methane formers. A 50% inoculum (based on total fermenter volume) was found to be most effective. Methane formers tended to aggregate to form spherical particles which had extremely high settling rates, this eliminated the requirement of cell recycle. They obtained the nutrients required for their growth through …

Evaluation Of A Polymer Film Impregnated With Reagent For The Detection And Determination Of Chlorine In Air., Khudre Muhammad Attar Jan 1982

Evaluation Of A Polymer Film Impregnated With Reagent For The Detection And Determination Of Chlorine In Air., Khudre Muhammad Attar

LSU Historical Dissertations and Theses

A new method for the direct detection and determination of chlorine in air has been devised. The method is based on the permeation of the gas through a silicone-polycarbonate copolymer film impregnated with a colorimetric reagent. The impregnation of the film with reagent was achieved by dissolving both a polymer film and a reagent in a common volatile solvent (CHCl(,3)), followed by casting on a leveled surface to allow the solvent to evaporate, thus forming a polymer film containing suspended reagent. The polymer films impregnated in such manner, were uniform and transparent. A spectrophotometer was used for monitoring the change …

Two-Dimensional Electron Layers In External Fields: Analysis Of The Effects Of Non-Separability., Samir Kumar Bhattacharya Jan 1982

Two-Dimensional Electron Layers In External Fields: Analysis Of The Effects Of Non-Separability., Samir Kumar Bhattacharya

LSU Historical Dissertations and Theses

Two-dimensional electron layers when placed in external electric and magnetic fields can display interesting features which arise solely due to the non-separability of electronic motions. Through simple, single electron Hamiltonians, we have studied in considerable details the effects of the nonseparability on the eigenvalue structure of two distinct systems. Intersubband cyclotron combined resonances in a quasi-two-dimensional space charge layer as found in metal-oxide-semiconductor sandwiches are studied using "triangular well" approximation. Two alternative basis sets have been pointed out which enable one to obtain analytical matrix elements of the Hamiltonian for all values of the magnitude and the angle of tilt …

Psychophysiological Concomitants Of Levels Of Cognitive Processing., Ronald Alan Cohen Jan 1982

Psychophysiological Concomitants Of Levels Of Cognitive Processing., Ronald Alan Cohen

LSU Historical Dissertations and Theses

The peripheral electrophysiological manifestations of levels of cognitive processing and memory performance were investigated by recording heart rate, skin conductance, skin temperature and electromyogram measures during a three phase verbal task. Subjects processed words at three cognitive levels (phonetic, low semantic, high semantic), and physiological recordings were made during cue covert processing and verbalization phases. Three colored lights were used to cue subjects to the appropriate processing level for each word. An incidental memory task was given following the processing tasks. As expected, words processed at the higher cognitive levels were recalled better. There was greater physiological reactivity associated with …

Rural Community Influentials: Participation In Local Voluntary Organizations., Jusoh Nordin B Muhamad Jan 1982

Rural Community Influentials: Participation In Local Voluntary Organizations., Jusoh Nordin B Muhamad

LSU Historical Dissertations and Theses

The purpose of this study is to identify the variables or types of variables that are possible predictors of organizational participation. Three categories of independent variables--ecological, situational, and individualistic variables are investigated. The sample consists of 442 rural community influentials from twelve counties in six southern states. Both the Spearman's test of correlation as well as multiple regression analysis are employed to assess the relationships among the independent and dependent variables. The zero-order correlations show that ecological variables (population size, percent white, and urbanization) and situational variables (organization availability and organization diversity) are generally highly correlated with organizational participation (p < 0.001). On the other hand, individualistic variables (occupation, education, age, and length of residence) are generally not significantly related to organizational participation, particularly in membership in influential organizations. The multiple regression analysis reveals that the three categories of variables account for about 20 percent of the variance in membership in influential organizations, and about 15 percent of the variance in the general measures of participation (simple memberships in any set of organizations, attendance at meetings and holding offices). Situational variables are found to have the most influence on membership in influential organizations, whereas population size (an ecological variable) is found to have the most influence on participation as indicated by the general measures of participation. Situational variables account for about 13.5 percent of the variance in membership in influential organizations, although the percentage of explained variance in the general measures of participation is less than 2 percent. Ecological variables, on the other hand, account for about 9 percent of the variance in organizational participation. One of the important tasks of the study is to examine whether organizational participation is related to community influence. Although there is some evidence that participation is associated with influence, the amount of variance explained by organizational participation is rather weak (less than 9 percent). Overall, the study suggests that structural variables (ecological and situational variables) are more important predictors of participation than individualistic variables. Hence, any explanation of the phenomenon of participation will be incomplete if structural factors are ignored.

Recent Trends In Coronary Risk Factors In The Ussr, R. Cooper, A. Schatzkin Jan 1982

Recent Trends In Coronary Risk Factors In The Ussr, R. Cooper, A. Schatzkin

Faculty Publications

The Soviet Union has experienced an increase in the incidence of coronary heart disease over the last 15 years sufficient to result in an overall deterioration in the health of adults. The distribution of coronary risk factors, and the secular trends in diet and cigarette consumption provide a potential explanation for the upsurge in death rates. The animal fat content of the Soviet diet has been steadily enriched since the 1950s and cigarette production increased 72 per cent from 1959 to 1980. The post-Stalin orientation of the Soviet economy toward a policy of motivating the work force primarily through the …
