Pattern And Variation In Prehistoric Lithic Resource Exploitation In The Passamaquoddy Bay Region, Charlotte County, New Brunswick, Anita L. Crotts

Electronic Theses and Dissertations

This study examines some factors that affected choice and use of lithic resources among prehistoric peoples living within a restricted geographical area during a period of 2500 years. The raw materials of chipped stone tools from six shell middens, habitation sites in the Passamaquoddy Bay region of southwestern New Brunswick, are identified. These include rocks that are atypical of the regional geology. Source areas of indigenous materials are located. Canoe transport made the native resources accessible to the inhabitants of the sites under study, and probably facilitated acquisition of non-native rocks.

The effect that distance had on lithic resource exploitation …

Reduced Tillage Effects On Weed Control, Soil Properties, And Dominant Weed Species In Southeastern South Dakota, Mark A. Wrucke

Electronic Theses and Dissertations

In recent years, farmers have made dramatic changes in their tillage practices. The conventional plow-disk-drag system allows farmers to control weeds, remove crop residue, and prepare the soil for planting. The development of 2,4-D [(2,4-dichlorophenoxy) acetic acid] in the 1940’s and of additional herbicides since then has greatly reduced the need for tillage to control weeds. Improvements in planting equipment allow farmers to use crop residue to their benefit. Farmers using tillage systems which leave residue on the soil surface can realize savings of time, labor, and equipment together with increased moisture and soil conservation while. maintaining yields equal to …

The Theory And Practice Of Misspelling : A Linguistic Analysis, Judy Frasch Worman

Electronic Theses and Dissertations

The freshmen at South Dakota State University are primarily students who have lived their entire lives in small agricultural communities. They are neither stupid nor unintelligent but merely inexperienced in writing formal exposition. Many of them come from towns with populations under one-thousand and high school graduating classes of twenty-five to fifty. Their primary means of communication (up until they enrolled in college) was through speech. Because they rarely write, they feel very uncomfortable about learning to write effectively. For the most part, these inexperienced writers are bright but unable to express themselves orthographically. There were some who, in spite …

Flameless Atomic Absorption Study Of Cobalt And Nickel In Black And White Display Screen Glass, Hui-Chieh Wang

Electronic Theses and Dissertations

A small quantity of nickel oxide and cobalt oxide is often added to the screen glass for both black and white and color television screens. These oxides give the glass a primarily neutral grey color. The purpose is to mitigate the influence of light sources outside the television set. Reflection of light from these sources against the luminescent layer can result in a noticeable reduction of the picture contrast. The effect of these colored oxides is based on the fact that the light reflected by the lumines cent layer passes through the screen glass twice and the light emitted by …

Stereochemistry Of Reactive Intermediates In Organophosphorous Chemistry, Alagappan Thenappan

Electronic Theses and Dissertations

A new synthetic route to produce a phosphonyl radical in the ground state has been devised. The radical is capable of maintaining its structural integrity and geometry. In polar aprotic solvents the radical can equilibrate depending upon reaction conditions. Our results are significant for they show that the homolytic cleavage of a phosphorous oxygen bond could by changing the configuration at phosphorous, influence the biological properties of naturally occurring compounds. The stereochemistry of 2-substituted-5-ch1oromethyl-5methy1-2-oxo-1,3,2-dioxaphosphorinans can be established by proton NMR spectroscopy. Methanolysis of 2-hydrazinophosphorinans has been investigated. Cis and trans 2-hydrazinophosphorinans undergo acid catalyzed methanolysis to give products of both …

Robert Bly And The Twofold Consciousness, Mary A. Thelen

Electronic Theses and Dissertations

"How beautiful to walk out at midnight in the moonlight/ dreaming of animals." It is samplings of Robert Bly's poetry such as these which have prompted Eliot Weinberger to wonder, "What kind of windbag and language slob would write such a line?" But there are also such fine and startling images as "The bare trees more dignified than ever" or "lamplight that falls on all fours in the grass," which Ian Hamilton admires. Hayden Carruth has encapsulated the view of many of Bly's readers, who regard him as one of the most annoying and exciting poets of the 1960's and …

The Effect Of Varying Lysine Levels In Starter Diets On Pig Performance And On Subsequent Performance And Carcass Characteristics, Robert C. Thaler

Electronic Theses and Dissertations

Lysine is the first limiting amino acid in most cereal-based diets for swine. Thus, in cereal-based diets the lysine- requirement must be met first if the pig's protein anabolism is to be efficient and maximal. The most widely used diet in the swine industry today is the corn-soybean meal diet. Corn is deficient in lysine, but soybean meal is a relatively good source of lysine, so soybean. meal is added to the corn base to increase the diet's lysine content. Synthetic lysine also can be added to corn-soybean meal diets to increase lysine content or added as a replacement for …

Of the three chemical parameters measured, conductivity of surface water appeared to have the greatest influence on the …

The Effects Of Steel Fibers On The Plastic Rotation Capacity And Properties Of Reinforced Concrete Continuous Beams, Khani Sahebjam

Electronic Theses and Dissertations

During the development of structural engineering, many ideas and concepts were considered and tested. A great deal of research has been done on reinforced concrete, which plays a significant role in current structural construction. Over the past decades there has been a competition between concrete and steel structures. Both concrete and steel structures have some advantages and disadvantages. Obviously, depending on the type of structure, choosing the right alternative is important. Reinforced concrete structures, unlike steel structures, tend to fail in a relatively brittle manner because the deformation capacity of reinforced concrete is limited. When dynamic loadings are involved, concrete …

Correlation Of Soil Moisture With Soil Surface Temperature Obtained By Thermography, Daniel Paul Roesler

Electronic Theses and Dissertations

Since the atmosphere attenuates the radiation emitted by the earth, the actual surface temperature is difficult to measure accurately from satellite heights. However, the temperature difference between two locations on the earth can be measured to a better approximation if the atmosphere attenuates the radiation equally over both surfaces. Thus, the temperature difference between two locations is more accessible than the actual surface temperature of each surface. If surface temperature difference does correlate to soil moisture difference, then relative moisture content can be calculated. Consequently, if a reference moisture is available for one location, the moisture content of the soil …

Selenium And Arsenic Interaction In The Rat, Cecile Younan Andraos

Electronic Theses and Dissertations

Selenium was discovered by Berzelius and Gahn in 1817 while they were examining the sediment from a sulfuric acid plant at Gripsholm, Sweden. However, it was not until 1929 that the greatest interest in selenium and its compounds was aroused in relation to its toxic effects in the animal body. At that time, Franke at the South Dakota Experiment Station and other workers discovered that selenium was the toxic agent causing "Alkali disease", a chronic poisoning that affects livestock raised in certain areas of the Great Plains of the United States. It was found that certain plants could take up …

Chemistry Of Phosphate Esters : Stereochemical Evidence For A Dissociative Mechanism, Mohammed Hashmat Ali

Electronic Theses and Dissertations

Many attempts have been made to elucidate the various mechanism by which phosphates act in biological and other systems. There are many suggestions regarding mechanisms all of which fit into one of two broad categories. 1. Associative. 2. Dissociative. Of these two, interest to the associative type displacement has been of most investigators and this pathway has been established with certainty. On the other hand, less work has been done and there has been much controversy surrounding the dissociative mechanism. The dissociative mechanism is believed to be important because it has been thought that it represents the actual biological processes …

Love In Major Novels Of Carson Mccullers, Lynn Margaret Butterbrodt

Electronic Theses and Dissertations

Mrs. McCullers was not a prolific writer; this was largely due to the fact that she was hindered throughout much of her life by serious illnesses. When she was fifteen, doctors misdiagnosed rheumatic fever as "pneumonia with complications.” Her heart was severely damaged by this illness; consequently, she suffered strokes which resulted in blindness in one eye, complete paralysis of her left side, and complications therefrom. Her final stroke in 1967 left her comatose for forty-seven days until her death on September 29, 1967, at age fifty. Her doctors believed that had her early illness been correctly diagnosed, her lifestyle …

Electronic Theses and Dissertations

The widespread use of pesticides during the last two decades has played an important role in the development of today's agricultural system and is one of the major topics of modern science. It is also expected to assist in meeting the nutritional needs of the rapidly expanding populations in the world. The organophosphorus insecticides are among the most toxic pesticides employed for agricultural pest control. However, organophosphorus insecticides are usually rapidly degraded and eliminated. There has been a great amount of study on the chemical, microbial, and physical factors affecting degradation of organophosphorus insecticides, but degradation pathways and behavior have …

Grazing Potential Of Major Soils Within The Black Hills Of South Dakota, Daryle L. Bennett

Electronic Theses and Dissertations

Silvicultural management applied by the United States Forest Service (USFS) utilizes a system of intermediate thinning cuts rather than clearcutting. This practice results in a rich understory of vegetation supporting significant wildlife populations. In 1980, 62,000 deer were estimated to be present within the Black Hills. The understory, in conjunction with the adjacent open parks and stream meadows, also supports another valuable resource the livestock industry. Over 29,000 cattle grazed nearly 486,000 hectares of Black Hills National Forest grazing allotments in 1980, totaling approximately 128,000 AUMs (animal unit months) seasonally. However, only 194,000 hectares of forest are classified as suitable …

The Effects Of Limited Energy Supplementation On Pasture And Level Of Dietary Energy In The Feedlot On The Finishing Performance And Carcass Traits Of Beef Cattle, Mark J. Goetz

Electronic Theses and Dissertations

Traditionally, pasture and range have been the major source of nutrients for grazing animals. The manner by which ruminants survive and thrive on range with no additional nutrients other than those supplied by forage is unique in the animal kingdom. Nevertheless, western man has cultivated a taste for grain-finished beef. To meet that demand, modern beef production involves both the grazing of forages and the feeding of rations high in concentrates. Major disruptive changes, either physical (as in prolonged drought) or economical (fluctuation in market prices) encourage the reexamination of traditional systems. Within the last 10 years, extreme fluctuations in …
