The Effect Of Pulp Mill Effluents On The Carbon Dioxide Evolution Of Three East Texas Soils, John C. Morris
The Effect Of Pulp Mill Effluents On The Carbon Dioxide Evolution Of Three East Texas Soils, John C. Morris
Electronic Theses and Dissertations
Two pulp mill effluents, NaOH extraction water from the pulp bleaching process and water from the chlorination step of the pulp bleaching process, were applied to jars containing three East Texas soils. Carbon dioxide evolution was then measured with an infrared gas analyzer to determine the effect of the effluents on the respiration of soil microorganisms. The relationship between effluent treatments was not statistically significant, though detrimental effects were observed in the heavier soil. Irrigation of clays and clay loams with the effluent is not recommended. Irrigation of sandy soils should be possible if there is no danger of sub-surface …
Computer Simulation Of Unsteady Flow In An Alluvial Channel By The Method Of Characteristics, Dennis Lynn Richards
Computer Simulation Of Unsteady Flow In An Alluvial Channel By The Method Of Characteristics, Dennis Lynn Richards
Electronic Theses and Dissertations
A number of dams have been constructed along alluvial rivers. These dams create reservoirs which serve to collect and store water, usually in large quantity, for use in supplying municipal needs, for supplying power and driving machinery, for furnishing irrigation, and for retaining the flow in time of floods. The characteristics of flow and the sediment-transport capacity of the channel change after these dams have been constructed. One of the major problems then confronting the hydraulic engineer is the rate of reservoir sedimentation and the change in river configuration. A problem of concern is the rapidity of reservoir sedimentation and …

Effects Of Chick Stimuli And Dieldrin On Adoptive Behavior Of Penned Hen Pheasants, K. L. Cool
Effects Of Chick Stimuli And Dieldrin On Adoptive Behavior Of Penned Hen Pheasants, K. L. Cool
Electronic Theses and Dissertations
Studies to determine the effect of chick stimuli and dieldrin on adoptive behavior of penned hen pheasants were conducted in 1969 and 1970. Results indicated that whether caged hens saw or heard chicks had no effect on adoption or killing of chicks. Hens receiving sound stimuli and sight-and-sound stimuli from chicks responded similarly to hens receiving no stimuli. Sub-lethal doses of dieldrin also had no effect on chick adoption under the conditions of this study. Results demonstrated that non-incubating pheasant hens will adopt and brood orphan chicks. During the 2 years of the study, respectively, 37 and 49 percent of …

Macroscopic Benthos Populations And Taxonomy Of The Family Chironomidae In Lake Poinsett, South Dakota, Stephen B. Smith
Electronic Theses and Dissertations
Benthos samples were collected in Lake Poinsett, a highly eutrophic eastern South Dakota lake, from March 1970 through February 1971. The lake bottom was divided into three substrate types (sand, sand-sapropel mixture and sapropel) and the percent of each substrate type was calculated. Nineteen macroscopic genera were taken from ten sampling stations located throughout the lake. Descriptions are presented for organisms in this group. Diversity of organisms was greatest in the sand substrates, in that all 19 genera were collected. Chironomus spp. (Chironomus plomosus, Chironomus attenuates and six unidentified species) was the most abundant group of organisms and occurred most …
Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger
Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger
Electronic Theses and Dissertations
Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. Bacteria numbers tend to increase as the protozoa numbers decrease. Knowledge of rumen microflora population changes on different rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and …
The Lipid Composition Of Milk As Affected By High Grain-Limited Roughage Rations Containing Whey Products, Roger Charles Peper
The Lipid Composition Of Milk As Affected By High Grain-Limited Roughage Rations Containing Whey Products, Roger Charles Peper
Electronic Theses and Dissertations
Certain rations fed to lactating dairy cows appear to have a dramatic influence on the lipid composition of milk fat produced. A high grain ration fed with a limited amount of roughage tends to cause a depression in milk fat production while at the same time changing the milk fat composition. There have been various attempts to alleviate the depression in milk fat. Minerals used in the ration seem to slightly relieve the milk fat depression caused by high grain rations. One drawback has been lower milk production due to a decline in concentrate consumption. Whey products added to a …
Speech Training And Speech Activities In Institutions Of Higher Education In Taiwan, Chang Yuh-Sheng
Speech Training And Speech Activities In Institutions Of Higher Education In Taiwan, Chang Yuh-Sheng
Electronic Theses and Dissertations
An M.A. thesis in speech on the status of speech training in Taiwan, China, is proposed. From personal experience, this author has discovered some difficulties which Chinese students meet when they take up speech in American universities. The chief reason for this might be that the Chinese students who study speech in American universities and colleges have a somewhat limited knowledge of the speech areas and an. inadequate background of speech training. Since speech courses are elective in most of the universities in Taiwan, the students' interest in participating in speech activities, such as speech contest and ·dramatic performance, has …

A Separator For Fine Sediments, Jung-Chiun Sun
Electronic Theses and Dissertations
In the field of sedimentation, researchers have been frequently confronted with the problem of separating fine sediments into different sizes. During the last two decades, much effort has been extended on the size analysis of sediments and numerous reports on methods of sediment size analysis have been published. Among these various methods, sieve analysis and V.A. Tube analusis developed by the U.S. Geological Survey have been found to be quite adequate for the analysis of coarse and medium sand of diameter larger than 0.1 mm (1). For fine sand analysis, some methods, such as decantation, elutriation, and incremental (2), are …

Horizontal Resistance To Leaf Rust In Spring Wheat, Mayo E. Wetterberg Jr.
Horizontal Resistance To Leaf Rust In Spring Wheat, Mayo E. Wetterberg Jr.
Electronic Theses and Dissertations
Stem rust, Puccina graminis tritici Eriks. And Henn., and leaf rust, Puccinia recondite Rob. Ex Desm., have been major diseases of wheat in the northern great plains for many years. As a result of several severe wheat rust epidemics within the past 50 years, much effort has been directed toward control of these diseases. Resistant varieties have been introduced over the years, but wheat rusts remain serious problems, causing losses to farmers in spite of breeding efforts. Since the discovery that both stem and leaf rust exist in several biological forms called races (18, 25), wheat breeding has been develop …

A Study Of The Endogenous Electron Donors For Nitrogen Fixation By Cell-Free Extracts Of Klebsiella Pneumoniae M5al (Aerobacter Aerogenes M5al), Elisabeth Yi-Jan Wu
Electronic Theses and Dissertations
Biological nitrogen fixation, the mechanism of the enzymatic conversion of the inert nitrogen gas into amino acids in the cytoplasm of the microorganism has puzzled many scientists for decades. The recent discovery of some free-living nitrogen-fixing bacteria has encouraged the investigation of this mechanism. A big step taken in the rapid elucidation of this mechanism was the first reproducible cell-free nitrogen-fixing system from Clostridium pasteurianum successfully obtained by Carnahan et al. (9) in 1960. In the following decade, reproducible cell-free systems were demonstrated with the strict aerobe, Azotobacter vinelandii (4), facultative anaerobic Bacillus polymyxa (16) and Klebsiella pneumoniae (31) and …

A Comparison Of An Individualized English Program With A Traditional English Program In Desmet High School, Beverly Jean Wolkow
Electronic Theses and Dissertations
With the incredible amount of information being uncovered each day and with the emphasis swinging from subject-centered curriculum to child-centered curriculum, education is in turmoil. Educators realize students cannot learn all the facts needed for the future. Since many people will have to retrain for new jobs several times in their lifetimes, students today probably cannot even learn enough for continuous occupation. To meet these challenges, educators have been searching for new methods of organization and instruction. One such method is individualized instruction. The purpose of initiating and studying a program of individualized instruction in English was to establish the …

Screening Electrocardiograms Using Hotelling's Method Of Principle Components, Edward G. Schwartz
Electronic Theses and Dissertations
Considerable use is presently being made of computers to classify electrocardiograms (ECGs) into various heart defect categories. An example of such a program is the "Electrocardiographic Analysis Program" developed jointly by the Mayo Clinic and IBM. In one of Dr. Caceres published reports, he tells of using a computer program which involves 5,000 instructions. Dr. Caceres does not say whether this is a commercial program or one of bis own. His description does place this program in the same general category as IBM's. These programs have the common criteria of examining the ECG for the same information that a cardiologist …
