Wetland Flow and Salinity Budgets and Elements of a Decision Support System toward Implementation of Real-Time Seasonal Wetland Salinity Management

The project has provided science-based tools for the long-term management of salinity in drainage discharges from wetlands to the San Joaquin River. The results of the project are being used to develop best management practices (BMP) and a decision support system to assist wetland managers adjust the timing of salt loads delivered to the San Joaquin River during spring drawdown. Adaptive drainage management scheduling has the potential to improve environmental compliance with salinity objectives in the Lower San Joaquin River by reducing the frequency of violation of Vernalis salinity standards, especially in dry and critically dry years. The paired approach to project implementation whereby adaptively managed and traditional practices were monitored in a side-by-side fashion has provided a quantitative measure of the impacts of the project on the timing of salt loading to the San Joaquin River. The most significant accomplishments of the project has been the technology transfer to wetland biologists, ditch tenders and water managers within the Grasslands Ecological Area. This “learning by doing” has build local community capacity within the Grassland Water District and California Department of Fish and Game providing these institutions with new capability to assess and effectively manage salinity within their wetlands while simultaneously …

Oral History Interview with William L. Bonning, December 13, 2011

The National Museum of the Pacific War presents an oral interview with William L. Bonning. Bonning had finished high school in 1941 and was grinding gears at Ford Motor Company in Detroit when he was drafted into the Army in January 1943. After a few failed attempts at joining the paratroopers, Bonning finally managed to pass the height requirement by stuffing matchbooks in his socks. He joined the paratroopers at Fort Benning, Georgia, in June, 1944. Bonning speaks of his experiences while training in Texas and Louisiana. He was in B Company, 504th Parachute Infantry Regiment, 82nd Airborne Division. He made it to France just in time to be moved to Belgium and join the fighting at the Battle of the Bulge. He shares many anecdotes about his time spent in combat and mentions many of his comrades by name.

International Low Level Waste Disposal Practices and Facilities (open access)

International Low Level Waste Disposal Practices and Facilities

The safe management of nuclear waste arising from nuclear activities is an issue of great importance for the protection of human health and the environment now and in the future. The primary goal of this report is to identify the current situation and practices being utilized across the globe to manage and store low and intermediate level radioactive waste. The countries included in this report were selected based on their nuclear power capabilities and involvement in the nuclear fuel cycle. This report highlights the nuclear waste management laws and regulations, current disposal practices, and future plans for facilities of the selected international nuclear countries. For each country presented, background information and the history of nuclear facilities are also summarized to frame the country's nuclear activities and set stage for the management practices employed. The production of nuclear energy, including all the steps in the nuclear fuel cycle, results in the generation of radioactive waste. However, radioactive waste may also be generated by other activities such as medical, laboratory, research institution, or industrial use of radioisotopes and sealed radiation sources, defense and weapons programs, and processing (mostly large scale) of mineral ores or other materials containing naturally occurring radionuclides. Radioactive waste …

Patronage, Connoisseurship and Antiquarianism in Georgian England: The Fitzwilliam Music Collection (1763-1815) (open access)

Patronage, Connoisseurship and Antiquarianism in Georgian England: The Fitzwilliam Music Collection (1763-1815)

In eighteenth-century Britain, many aristocrats studied music, participated as amateurs in musical clubs, and patronized London’s burgeoning concert life. Richard Fitzwilliam, Seventh Viscount Fitzwilliam of Merrion and Thorncastle (1745-1816), was one such patron and amateur. Fitzwilliam shaped his activities – participation, patronage, and collecting – in a unique way that illustrates his specialized tastes and interests. While as an amateur musician he sang in the Noblemen’s and Gentlemen’s Catch Club (the premiere social club dedicated to musical performance), he rose to the highest level of patronage by spearheading the Handel Commemoration Festival of 1784 and serving for many years as a Director of the Concert of Antient Music, the most prestigious concert series in Georgian Britain. His lasting legacy, however, was his bequest to Cambridge University of his extensive collection of art, books and music, as well as sufficient funds to establish the Fitzwilliam Museum. At the time of his death, Fitzwilliam’s collection of music was the best in the land, save that in the Royal Library. Thus, his collection is ideally suited for examination as proof of his activities, taste and connoisseurship. Moreover, the music in Fitzwilliam’s collection shows his participation in the contemporary musicological debate, evidenced by his …

Effect of Rancher’s Management Philosophy, Grazing Practices, and Personal Characteristics on Sustainability Indices for North Central Texas Rangeland (open access)

Effect of Rancher’s Management Philosophy, Grazing Practices, and Personal Characteristics on Sustainability Indices for North Central Texas Rangeland

To assess sustainability of privately owned rangeland, a questionnaire was used to gathered data from ranches in Cooke, Montague, Clay, Wise, Parker, and Jack counties in North Central Texas. Information evaluated included: management philosophy, economics, grazing practices, environmental condition, quality of life, and demographics. Sustainability indices were created based on economic and land health indicator variables meeting a minimum Cronbach‘s alpha coefficient (α = 0.7). Hierarchical regression analysis was used to create models explaining variance in respondents’ indices scores. Five predictors explained 36% of the variance in rangeland economic sustainability index when respondents: 1) recognized management inaction has opportunity costs affecting economic viability; 2) considered forbs a valuable source of forage for wildlife or livestock; 3) believed governmental assistance with brush control was beneficial; 4) were not absentee landowners and did not live in an urban area in Texas, and; 5) valued profit, productivity, tax issues, family issues, neighbor issues or weather issues above that of land health. Additionally, a model identified 5 predictors which explained 30% of the variance for respondents with index scores aligning with greater land health sustainability. Predictors indicated: 1) fencing cost was not an obstacle for increasing livestock distribution; 2) land rest was a component …

Pahute Mesa Well Development and Testing Analyses for Wells ER-20-7, ER-20-8 #2, and ER-EC-11, Revision 1 (open access)

Pahute Mesa Well Development and Testing Analyses for Wells ER-20-7, ER-20-8 #2, and ER-EC-11, Revision 1

This report analyzes the following data collected from ER-20-7, ER-20-8 No.2, and ER-EC-11 during WDT operations: (1) Chemical indicators of well development (Section 2.0); (2) Static hydraulic head (Section 3.0); (3) Radiochemistry and geochemistry (Section 4.0); (4) Drawdown observed at locations distal to the pumping well (Section 5.0); and (5) Drilling water production, flow logs, and temperature logs (Section 6.0). The new data are further considered with respect to existing data as to how they enhance or change interpretations of groundwater flow and transport, and an interim small-scale conceptual model is also developed and compared to Phase I concepts. The purpose of well development is to remove drilling fluids and drilling-associated fines from the formation adjacent to a well so samples reflecting ambient groundwater water quality can be collected, and to restore hydraulic properties near the well bore. Drilling fluids can contaminate environmental samples from the well, resulting in nonrepresentative measurements. Both drilling fluids and preexisting fines in the formation adjacent to the well can impede the flow of water from the formation to the well, creating artifacts in hydraulic response data measured in the well.

Student to Teacher Racial/Ethnic Ratios as Contributors to Regional Achievement Gaps, 1999-2008 (open access)

Student to Teacher Racial/Ethnic Ratios as Contributors to Regional Achievement Gaps, 1999-2008

With the advent of No Child Left Behind legislation in 2002 and its mandates for annual yearly progress for all students, many districts and schools in Texas have had difficulty elevating African American and Hispanic students’ scores. The current study examined these students’ achievement on the annual Texas high-stakes measure as a function of a numerical construct that aligns the race/ethnicity of students when the teacher race is White. Earlier studies have shown that racial/ethnic compatibility between students and teachers improves student achievement in the primary grades. The study, which was set in 10 north Texas school districts and 30 high schools, middle schools, and elementary schools, examined African American and Hispanic students’ achievement on the Texas state assessments in reading and mathematics over a 10-year period. District performance data came from 4,664,192 African American, Hispanic, and White students and 222, 834 White teachers. Campus level data encompassed 188,839 10th graders, 93,573 eighth graders, and 40,083 fourth graders, and 20,471 White teachers. Analysis revealed that, as the ratios of African American and Hispanic students to White teachers increased, the percentages of these two student groups passing the Texas assessments decreased. These patterns differed for White students whose passing percentages increased …

NGNP Project 2011 Status and Path Forward (open access)

NGNP Project 2011 Status and Path Forward

High Temperature Gas Reactor (HTGR) technology can play an important role in the United States’ energy future by extending the use of nuclear energy for non-electricity energy production missions as well as continuing to provide a considerable base load electric power generation capability. Extending nuclear energy into the industrial and transportation sectors through the co-production of process heat and electricity provides safe and reliable energy for these sectors in an environmentally responsible manner. The safety case for the modular HTGR provides a substantial improvement in nuclear plant safety for the protection of the public and the environment, and supports collocation of the HTGR with major industrial facilities. The NGNP Project at the Idaho National Laboratory has been working toward an objective of commercializing the HTGR technology under DOE direction since 2006. The Project is undergoing a quantum shift in direction and scope as a result of recent DOE decisions. This paper summarizes where the Project has been, where it is at the time of this writing and what is needed in future activities to commercialize HTGR technology.

The Magellan Final Report on Cloud Computing (open access)

The Magellan Final Report on Cloud Computing

The goal of Magellan, a project funded through the U.S. Department of Energy (DOE) Office of Advanced Scientific Computing Research (ASCR), was to investigate the potential role of cloud computing in addressing the computing needs for the DOE Office of Science (SC), particularly related to serving the needs of mid- range computing and future data-intensive computing workloads. A set of research questions was formed to probe various aspects of cloud computing from performance, usability, and cost. To address these questions, a distributed testbed infrastructure was deployed at the Argonne Leadership Computing Facility (ALCF) and the National Energy Research Scientific Computing Center (NERSC). The testbed was designed to be flexible and capable enough to explore a variety of computing models and hardware design points in order to understand the impact for various scientific applications. During the project, the testbed also served as a valuable resource to application scientists. Applications from a diverse set of projects such as MG-RAST (a metagenomics analysis server), the Joint Genome Institute, the STAR experiment at the Relativistic Heavy Ion Collider, and the Laser Interferometer Gravitational Wave Observatory (LIGO), were used by the Magellan project for benchmarking within the cloud, but the project teams were also able …

Hide, Horn, Fish, and Fowl: Texas Hunting and Fishing Lore

Access: Use of this item is restricted to the UNT Community
What would cause someone to withstand freezing temperatures in a cramped wooden box for hours on end, or stand in waist-high rushing waters, flicking a pole back and forth over and over—in many cases with nothing whatsoever to show for his efforts? Why is it that, into the twenty-first century, with the convenience of practically any type of red meat or fish available at the local supermarket, we continue to hunt game and fish on open waters? The answer is that no matter how sophisticated we think we are, no matter how technologically advanced we become, there is still something deep within us that beckons us to “the hunt.” This desire creates the customs, beliefs, and rituals related to hunting—for deer, hogs, and other four-legged critters, as well as fish and snakes, and other things that perhaps aren’t physically alive, but capture our interest as much as the prey mentioned above. These rituals and customs lead to some of our most treasured stories, legends, and practices. This volume of the Publications of the Texas Folklore Society includes serious, introspective articles on hunting and fishing, as well as humorous tall tales and “windies” about the big ones that got away—all lore …
