A Study of the Knowledge and Skills Required of Draftsmen in the Dallas-Fort Worth Area

Craghead, Jane E. 06 1900 (has links)
This study was designed to identify the knowledge and skills that draftsmen employed in the greater Dallas-Forth Worth, Texas metropolitan area should posses. This study was conducted to identify the following as related to draftsmen in the Dallas-Forth Worth, Texas area: What kind of education and experience is required to prospective draftsmen? What are the general duties of draftsmen? How much emphasis is placed upon knowledge of and skill in the use of drafting equipment? How important are the basic concepts and principles of drafting usually taught in drafting courses? What methods are used to reproduce drawings?

Colonization of the East Texas Timber Region Before 1848

Baker, Willie Gene 08 1900 (has links)
For many years adventurers from Spain and France had explored Texas. For about fifty years Spain had tried to civilize and Christianize the Indians in East Texas. Finally the Spanish government had abolished the missions and presidios. During the following fifty years, very little had been done toward colonization in Texas. In 1821, Texas was an almost uninhabited country, with the exception of savage Indians. The Anglo-Americans came and changed it into a great state. The East Texas Timber Region has been the gateway through which most of the settlers came to Texas. The settlers who stopped there did their part in establishing the present state of Texas. The East Texans did their part in helping to win freedom from Mexico so they could lay a foundation for American civilization there.

QUATERNARY STRATIGRAPHY, GEOCHRONOLOGY, AND CARBON ISOTOPE GEOLOGY OF ALLUVIAL DEPOSITS IN THE TEXAS PANHANDLE (RADIOCARBON).

STAFFORD, THOMAS WIER, JR. January 1984 (has links)
Sedimentology, stratigraphy, and stable-carbon isotopy were used to reconstruct geologic and climatic events on the Texas southern High Plains from ca. 13,000 yr B.P. to the present. The alluvial sediments in Yellowhouse and Blackwater Draws were used to construct the geologic history. The oldest valley alluvium comprises the > 13,000-yr-B.P. fluvial sediments that were incised and buried by fluvial and lacustrine sediments dating ca. 13,000 to 4900 yr B.P. Lacustrine waters changed from oligotrophic to eutrophic and finally calcalitrophic. Regional valley erosion at 4900 yr B.P. developed a widespread disconformity within the Yellowhouse Draw formation, which separates lower fluvial and lacustrine sediments (ca. 13,000-4900 yr B.P.) from the overlying sediments dating 4900 yr B.P. to present. After 4900 yr B.P., intermittent streams and eolian processes deposited several meters of sand the length of each valley. Cienegas returned to downstream reaches of both draws after 1500-2000 yr B.P. Methods were developed to extract purified collagen residues and hydroxyproline from heavily contaminated fossil bones. Reliable δ¹³C measurements on collgen require isolation of single amino acids, whereas less specific purifications may yield accurate bone collagen ¹⁴C dates. Collagenous residues were extracted from 13,000-200-yr-B.P. fossil bison bones from the Lubbock Lack Site at Lubbock, Texas, and δ¹³C values were determined. Collagen δ¹³C values changed from -8 per mil at 200 yr B.P. to -10 per mil at 4900 yr B.P. and to -17 per mil at 12,500 yr B.P. The δ¹³C changes imply that the Lubbock area grasslands contained 30 to 40 percent C₄ grass biomass at 12,500 yr B.P. in contrast to the 95 percent C₄ grass biomass in today's grasslands. The stratigraphic and isotopic results gave similar paleoecological histories for the Texas southern High Plains. At 12,500 yr B.P. permanent streams existed and grasslands may have resembled those in the northern central Great Plains today. The climate warmed gradually, and the water table dropped until 5000 yr B.P. when a major hydrologic shift occurred. After 4900 yr B.P., modern climatic depositional and vegetation communities were developed. Geomorphic thresholds apparently controlled the regional disconformities, depositional events, and pedogenetic episodes. Climatic change was the ultimate cause of stratigraphic changes, but individual geologic events were not coeval with any similar climatic shift.

Trophogenic Ecology of Selected Southwestern Reservoirs

McDaniel, Michael David 05 1900 (has links)
Three north central Texas reservoirs (Grapevine Reservoir, Lake Ray Hubbard, Lewisville Reservoir) were investigated in order to characterize the nutritional ecology, phytoplankton community structure, and primary productivity within the trophogenic zones of each. Emphasis was placed on elucidating the relative influences of the major nutrients (C, N, P, Fe, Si) and various other physico-chemical parameters on phytoplankton community biomass, structure, and productivity. Extensive physical, chemical, and biological analyses consisting of approximately eighty parameter measurements were made on each of twenty-three integrated water samples (surface to three meters) taken from the three reservoirs during the period July, 1971 to June, 1972. New methods which were employed included a high-intensity ultraviolet photocombustion procedure for the determination of total nitrogen, phosphorus, and iron, and an in vitro oxygen method for estimating community metabolism. General chemical and physical regimes are described for the three reservoirs, and various interrelationships discussed. Phytoplankton communities are delineated on bases of species composition, volume, diversity, pigments, and metabolism data. The more salient biotic and physico-chemical interrelationships are examined within the context of the limiting nutrient controversy.

The Highsmith Men, Texas Rangers

Edwards, Cody 12 1900 (has links)
The Highsmith Men is a general historical narrative of four prominent men who happened to be Texas Rangers. The story begins in Texas in 1830 and traces the lives of Samuel Highsmith, his nephew, Benjamin Franklin Highsmith, and Samuels's sons, Malcijah and Henry Albert Highsmith, who was the last of the four to pass away, in 1930. During this century the four Highsmiths participated in nearly every landmark event significant to the history of Texas. The Highsmith men also participated in numerous other engagements as well. Within this framework the intent of The Highsmith Men is to scrutinize the contemporary scholarly conceptions of the early Texas Rangers as an institution by following the lives of these four men, who can largely be considered common folk settlers. This thesis takes a bottom up approach to the history of Texas, which already maintains innumerable accounts of the sometimes true and, sometimes not, larger than life figures that Texas boasts. For students pursuing studies in the Texas, the American West, the Mexican American War, or Civil War history, this regional history may be of some use. The early Texas Rangers were generally referred to as "Minute Men" or "Volunteer Militia" until 1874. In this role, the Highsmith men participated in many historic Texas engagements including but not limited to the Siege of Béxar, the battle of the Alamo, San Jacinto, the Cordova Rebellion, Plum Creek, the Mexican Invasions of 1842, the Mexican War, the Civil War, Salado Creek, Brushy Creek, and the capture of Sam Bass. Not only did people like the Highsmiths, who were largely considered "common folk," participate in these battles, they were also Texas Rangers. None of the Highsmith men were full time Texas Rangers, which discredits prominent stereotypes. The Highsmith Men shows that the Texas Ranger institution and the history of Texas itself was not dominated by larger than life historical characters, rather those noted figures maintained their widespread fame by building their successes on the backs of these men.
