Winchester Warriors: Texas Rangers of Company D, 1874-1901
Access:
Use of this item is restricted to the UNT Community
The Texas Rangers were institutionally birthed in 1874 with the formation of the Frontier Battalion. They were tasked with interdicting Indian incursions into the frontier settlements and dealing with the lawlessness running rampant throughout Texas. In an effort to put a human face on the Rangers, Bob Alexander tells the story of one of the six companies of the Frontier Battalion, Company D. Readers follow the Rangers of Company D as—over time—it transforms from a unit of adventurous boys into a reasonably well-oiled law enforcement machine staffed by career-oriented lawmen. Beginning with their start as Indian fighters against the Comanches and Kiowas, Alexander explores the history of Company D as they rounded up numerous Texas outlaws and cattle thieves, engaged in border skirmishes along the Rio Grande, and participated in notable episodes such as the fence cutter wars. Winchester Warriors is an evenhanded and impartial assessment of Company D and its colorful cadre of Texas Rangers. Their laudable deeds are explored in detail, but by the same token their shameful misadventures are not whitewashed. These Texas Rangers were simply people, good and bad—and sometimes indifferent. This new study, extensively researched in both primary and secondary sources, will appeal to scholars …

The use of microarrays in microbial ecology
Microarrays have proven to be a useful and high-throughput method to provide targeted DNA sequence information for up to many thousands of specific genetic regions in a single test. A microarray consists of multiple DNA oligonucleotide probes that, under high stringency conditions, hybridize only to specific complementary nucleic acid sequences (targets). A fluorescent signal indicates the presence and, in many cases, the abundance of genetic regions of interest. In this chapter we will look at how microarrays are used in microbial ecology, especially with the recent increase in microbial community DNA sequence data. Of particular interest to microbial ecologists, phylogenetic microarrays are used for the analysis of phylotypes in a community and functional gene arrays are used for the analysis of functional genes, and, by inference, phylotypes in environmental samples. A phylogenetic microarray that has been developed by the Andersen laboratory, the PhyloChip, will be discussed as an example of a microarray that targets the known diversity within the 16S rRNA gene to determine microbial community composition. Using multiple, confirmatory probes to increase the confidence of detection and a mismatch probe for every perfect match probe to minimize the effect of cross-hybridization by non-target regions, the PhyloChip is able to …

One Man's Music: the Life and Times of Texas Songwriter Vince Bell
Access:
Use of this item is restricted to the UNT Community
Texas singer/songwriter Vince Bell’s story begins in the 1970s. Following the likes of Townes Van Zandt and Guy Clark, Bell and his contemporaries Lyle Lovett, Nanci Griffith, and Lucinda Williams were on the rise. In December of 1982, Bell was on his way home from the studio (where he and hired guns Stevie Ray Vaughan and Eric Johnson had just recorded three of Bell’s songs) when a drunk driver broadsided him at 65 mph. Thrown over 60 feet from his car, Bell suffered multiple lacerations to his liver, embedded glass, broken ribs, a mangled right forearm, and a severe traumatic brain injury. Not only was his debut album waylaid for a dozen years, life as he’d known it would never be the same. In detailing his recovery from the accident and his roundabout climb back onstage, Bell shines a light in those dark corners of the music business that, for the lone musician whose success is measured not by the Top 40 but by nightly victories, usually fall outside of the spotlight. Bell’s prose is not unlike his lyrics: spare, beautiful, evocative, and often sneak-up-on-you funny. His chronicle of his own life and near death on the road reveals what …

Decision-Support Experiments and Evaluations using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources
This Synthesis and Assessment Product focuses on the connection between the scientific ability to predict climate on seasonal scales and the opportunity to incorporate such understanding into water resource management decisions. It directly addresses decision support experiments and evaluations that have used seasonal-to-interannual forecasts and observational data, and is expected to inform (1) decision makers about the relative success of experiences of others who have experimented with these forecasts and data in resource management; (2) climatologists, hydrologists, and social scientists on how to advance the delivery of decision-support resources that use the most recent forecast products, methodologies, and tools; and (3) science and resource managers as they plan for future investments in research related to forecasts and their role in decision support. It is important to note, however, that while the focus of this Product is on the water resources management sector, the findings within this Synthesis and Assessment Product may be directly transferred to other sectors.

Fluid effects on seismic waves in hard rocks with fractures and in soft granular media
When fractures in otherwise hard rocks are filled with fluids (oil, gas, water, CO{sub 2}), the type and physical state of the fluid (liquid or gas) can make a large difference in the wave speeds and attenuation properties of seismic waves. The present work summarizes methods of deconstructing theses effects of fractures, together with any fluids contained within them, on wave propagation as observed in reflection seismic data. Additional studies of waves in fluid-saturated granular media show that the behavior can be quite different from that for fractured media, since these materials are typically much softer mechanically than are the fractured rocks (i.e., having a very small drained moduli). Important fluid effects in such media are often governed as much by fluid viscosity as by fluid bulk modulus.

The Diaries of John Gregory Bourke: Volume 4, July 3, 1880-May 22, 1881
Access:
Use of this item is restricted to the UNT Community
John Gregory Bourke kept a monumental set of diaries beginning as a young cavalry lieutenant in Arizona in 1872, and ending the evening before his death in 1896. As aide-de-camp to Brigadier General George Crook, he had an insider's view of the early Apache campaigns, the Great Sioux War, the Cheyenne Outbreak, and the Geronimo War. Bourke's writings reveal much about military life on the western frontier, but he also was a noted ethnologist, writing extensive descriptions of American Indian civilization and illustrating his diaries with sketches and photographs. Previously, researchers could consult only a small part of Bourke’s diary material in various publications, or else take a research trip to the archive and microfilm housed at West Point. Now, for the first time, the 124 manuscript volumes of the Bourke diaries are being compiled, edited, and annotated by Charles M. Robinson III, in a planned set of eight books easily accessible to the modern researcher. Volume 4 chronicles the political and managerial affairs in Crook’s Department of the Platte. A large portion centers on the continuing controversy concerning the forced relocation of the Ponca Indians from their ancient homeland along the Dakota-Nebraska line to a new reservation in the …

OVERVIEW OF BERYLLIUM SAMPLING AND ANALYSIS
Because of its unique properties as a lightweight metal with high tensile strength, beryllium is widely used in applications including cell phones, golf clubs, aerospace, and nuclear weapons. Beryllium is also encountered in industries such as aluminium manufacturing, and in environmental remediation projects. Workplace exposure to beryllium particulates is a growing concern, as exposure to minute quantities of anthropogenic forms of beryllium may lead to sensitization and to chronic beryllium disease, which can be fatal and for which no cure is currently known. Furthermore, there is no known exposure-response relationship with which to establish a 'safe' maximum level of beryllium exposure. As a result, the current trend is toward ever lower occupational exposure limits, which in turn make exposure assessment, both in terms of sampling and analysis, more challenging. The problems are exacerbated by difficulties in sample preparation for refractory forms of beryllium, such as beryllium oxide, and by indications that some beryllium forms may be more toxic than others. This chapter provides an overview of sources and uses of beryllium, health risks, and occupational exposure limits. It also provides a general overview of sampling, analysis, and data evaluation issues that will be explored in greater depth in the remaining …

Saving Ben: a Father's Story of Autism
Access:
Use of this item is restricted to the UNT Community
Each year thousands of children are diagnosed with autism, a devastating neurological disorder that profoundly affects a person’s language and social development. Saving Ben is the story of one family coping with autism, told from the viewpoint of a father struggling to understand his son’s strange behavior and rescue him from a downward spiral. “Take him home, love him, and save your money for his institutionalization when he turns twenty-one.” That was the best advice his doctor could offer in 1990 when three-year-old Ben was diagnosed with autism. Saving Ben tells the story of Ben’s regression as an infant into the world of autism and his journey toward recovery as a young adult. His father, Dan Burns, puts the reader in the passenger’s seat as he struggles with medical service providers, the school system, extended family, and his own limitations in his efforts to pull Ben out of his darkening world. Ben, now 21 years old, is a work in progress. The full force and fury of the autism storm have passed. Using new biomedical treatments, repair work is underway. Saving Ben is a story of Ben’s journey toward recovery, and a family’s story of loss, grief, and healing. “Keep …

The Deadliest Outlaws: the Ketchum Gang and the Wild Bunch
Access:
Use of this item is restricted to the UNT Community
After Tom Ketchum had been sentenced to death for attempting to hold up a railway train, his attorneys argued that the penalty was “cruel and unusual” for the offense charged. The appeal failed and he became the first individual—and the last—ever to be executed for a crime of this sort. He was hanged in 1901; in a macabre ending to his life of crime, his head was torn away by the rope as he fell from the gallows. Tom Ketchum was born in 1863 on a farm near the fringe of the Texas frontier. At the age of nine, he found himself an orphan and was raised by his older brothers. In his mid-twenties he left home for the life of an itinerant trail driver and ranch hand. He returned to Texas, murdered a man, and fled. Soon afterwards, he and his brother Sam killed two men in New Mexico. A year later, he and two other former cowboys robbed a train in Texas. The career of the Ketchum Gang was under way. In their day, these men were the most daring of their kind, and the most feared. They were accused of crimes that were not theirs, but their …

Use of this item is restricted to the UNT Community
Interview with Dr. Victor Rodriguez, educator and author of the memoir "The Bell Ringer," about his life and career. Dr. Rodriguez is a North Texas alumni, member of the UNT Athletic Hall of fame, member of the Geezles Fraternity, and pioneer Mexican American educator. Dr. Victor Rodriguez spotlights significant insights into his storied career through five eras: his early all-Hispanic elementary school training; his continued study and budding athletic prowess in the Edna, TX, school district; his Victoria Junior College athletic achievements and learning; his higher education, Geezle membership, and track accomplishments at North Texas State College; and his 37-year career as a teacher, coach, and superintendent in the San Antonio school district. Inspired by his Anglo third-grade teacher in an all-Hispanic school in Edna, TX, Rodriguez responded to his teacher's challenge to be a civic contributor by becoming a daily bell ringer at the local Catholic church (described in detail in his book, The Bell Ringer), a job requiring him to arise at 4:30 each morning and to run two miles one way amid nipping dogs to ring the bell. This discipline and activity would tap his athletic ability later as he surfaced as a distance district winner despite …

Exceptional groups, symmetric spaces and applications
In this article we provide a detailed description of a technique to obtain a simple parameterization for different exceptional Lie groups, such as G{sub 2}, F{sub 4} and E{sub 6}, based on their fibration structure. For the compact case, we construct a realization which is a generalization of the Euler angles for SU(2), while for the non compact version of G{sub 2(2)}/SO(4) we compute the Iwasawa decomposition. This allows us to obtain not only an explicit expression for the Haar measure on the group manifold, but also for the cosets G{sub 2}/SO(4), G{sub 2}/SU(3), F{sub 4}/Spin(9), E{sub 6}/F{sub 4} and G{sub 2(2)}/SO(4) that we used to find the concrete realization of the general element of the group. Moreover, as a by-product, in the simplest case of G{sub 2}/SO(4), we have been able to compute an Einstein metric and the vielbein. The relevance of these results in physics is discussed.

Genomics of Secondary Metabolism in Populus: Interactions With Biotic and Abiotic Environments
Populus trees face constant challenges from the environment during their life cycle. To ensure their survival and reproduction, Populus trees deploy various types of defenses, one of which is the production of a myriad of secondary metabolites. Compounds derived from the shikimate-phenylpropanoid pathway are the most abundant class of secondary metabolites synthesized in Populus. Among other major classes of secondary metabolites in Populus are terpenoids and fatty acid-derivatives. Some of the secondary metabolites made by Populus trees have been functionally characterized. Some others have been associated with certain biological/ecological processes, such as defense against insects and microbial pathogens or acclimation or adaptation to abiotic stresses. Functions of many Populus secondary metabolites remain unclear. The advent of various novel genomic tools will enable us to explore in greater detail the complexity of secondary metabolism in Populus. Detailed data mining of the Populus genome sequence can unveil candidate genes of secondary metabolism. Metabolomic analysis will continue to identify new metabolites synthesized in Populus. Integrated genomics that combines various omics tools will prove to be the most powerful approach in revealing the molecular and biochemical basis underlying the biosynthesis of secondary metabolites in Populus. Characterization of the biological/ecological functions of secondary metabolites as …

Past Climate Variability and Change in the Arctic and at High Latitudes
This Climate Change Science Program Synthesis and Assessment Product addresses current capabilities to integrate observations of the climate system into a consistent description of past and current conditions through the method of reanalysis. In addition, the Product assesses present capabilities to attribute causes for climate variations and trends over North America during the reanalysis period, which extends from the mid-twentieth century to the present. This Product reviews Past Climate Variability and Change in the Arctic and at High Latitudes. Paleoclimate records play a key role in our understanding of Earth's past and present climate system and in our confidence in predicting future climate changes. Paleoclimate data help to elucidate past and present active mechanisms of climate change by placing the short instrumental record into a longer term context and by permitting models to be tested beyond the limited time that instrumental measurements have been available. Recent observations in the Arctic have identified large ongoing changes and important climate feedback mechanisms that multiply the effects of global-scale climate changes. As discussed in this report, paleoclimate data show that land and sea ice have grown with cooling temperatures and have shrunk with warming ones, amplifying temperature changes while causing and responding to …

A Simple Distributed Particle Swarm Optimization for Dynamic and Noisy Environments
In this paper, we present a Simple Distributed Particle Swarm Optimization (SDPSO) algorithm that can be used to track the optimal solution in a dynamic and noisy environment. The classic PSO algorithm lacks the ability to track changing optimum in a dynamic environment. Several approaches have been investigated to enhance the PSO algorithm s ability in dynamic environments. However, in dealing with dynamic environments, these approaches have lost PSO s original strengths of decentralized control and ease of implementation. The SDPSO algorithm proposed in this paper maintains these classic PSO features as well as provides the optimum result tracking capability in dynamic environments. In this research, the DF1 multimodal dynamic environment generator proposed by Morrison and De Jong is used to evaluate the classic PSO, SDPSO and other two adaptive PSOs.
