Characterization of a 1,4-. beta. -D-glucan synthase from Dictyostelium discoideum
Various aspects of research concerning Dictyostelium discoideum are presented. The initial focus of this project was upon: the characterization of potential probes for the cellulose synthase (antibody and nucleic acid), the determination of the cultural induction conditions of cellulose synthesis, the solubilization of the enzyme activity, the development of a non-inhibitory disruption buffer, the generation and isolation of mutant strains deficient in cellulose synthesis, and the development of the capability to determine the degree of polymerization of the in vitro product. I have briefly summarized our most significant findings with only selected data sets being shown in this report in the interest of brevity.

Cold Anger: a Story of Faith and Power Politics
Access:
Use of this item is restricted to the UNT Community
"Cold Anger is an important book about the empowerment of working-class communities through church-based social activism. Such activism is certainly not new, but the conscious merger of community organizing tactics with religious beliefs may be. The organizing approach comes from Aul Alinsky and his Industrial Areas Foundations (IAF). . . . The book is structured around the political life of Ernesto Cortes, Jr., the lead IAF organizer who has earned recognition as one of the most powerful individuals in Texas (and who has been featured on Bill Moyers' "World of Ideas"). . . . Cortes fashioned a hard-ball Alinsky approach onto the natural organizing ground of church-based communities. The experiment began in San Antonio . . . and was successful in the transformation of San Antonio politics. Such dramatic success . . . led to similar efforts in Houston, Fort Worth, El Paso, the Rio Grande Valley, Phoenix, Los Angeles, and New York, to mention only a few sites. Expansion beyond San Antonio meant organizing among Protestant churches, among African American and white, and among middle-class communities. In short, these organizing efforts have transcended the particularistic limits of religion, ethnicity, and class while maintaining a church base and sense of …

The Cowgirls
Access:
Use of this item is restricted to the UNT Community
An important chapter in the history and folklore of the West is how women on the cattle frontier took their place as equal partners with men. The cowboy may be our most authentic folk hero, but the cowgirl is right on his heels. This Spur Award winning book fills a void in the history of the cowgirl. While Susan B. Anthony and her hoop-skirted friends were declaring that females too were created equal, Sally Skull was already riding and roping and marking cattle with her Circle S brand on the frontier of Texas. Wearing rawhide bloomers and riding astride, she thought nothing of crossing the border into Mexico, unchaperoned, to pursue her career as a horse trader. In Colorado, Cassie Redwine rounded up her cowboys and ambushed a group of desperadoes; Ann Bassett, also of Colorado, backed down a group of men who tried to force her off the open range. In Montana, Susan Haughian took on the United States government in a dispute over some grazing rights, and the government got the short end of the stick. Susan McSween carried on an armed dispute between ranchers in New Mexico and the U.S. Army, and other interested citizens; and in …

Evaluation of Gas-Reburning and Low NOx Burners on a Wall Fired Boiler
Low NO{sub x} burners operate on the principle of delayed mixing between the coal fuel and burner air, so that less NO{sub x} is formed. Gas reburning is a combustion modification technique that consists of firing 80--85 percent of the fuel corresponding to the total heat release in the lower furnace. Reduction of NO{sub x} to molecular nitrogen (N{sub 2}) is accomplished via the downstream injection of the remaining fuel requirement in the form of natural gas (which also reduces the total SO{sub x} emissions). In a third stage, burnout air is injected at the lower temperatures in the upper furnace to complete the combustion process without generating significant additional NO{sub x}. The specific goal of this project is to demonstrate NO{sub x} emission reductions of 75 percent or more as a result of combing Low NO{sub x} Burners and Gas Reburning on a utility boiler having the design characteristics mentioned above. A Host Site Agreement has been signed by EER and a utility company in the State of Colorado: Public Service Company of Colorado (Cherokee Unit No. 3, 172 MW{sub e}) front wall fired boiler near Denver.

Air gun test evaluation
A mechanical shock testing apparatus is used for testing the response of components subject to large accelerations in hostile environments. The test acceleration is provided by the impact of a bullet against a plate on which the component to be tested is mounted. This report describes a series of experiments that were performed to determine the dependence of the air gun test apparatus performance on incremental changes in the hardware configurations, changes in the pressure used to drive the bullet, and different accelerometers. The effect of variation of these experimental factors on the measured acceleration was determined using a Taguchi screening experimental design. Experimental settings were determined that can be used to operate the tester with a measured output within acceleration specifications.

Role of structure in ion movement of glasses
Can the structure of a melt much above the glass transition temperature (Tg) determine the structure and (transport) properties of glass In other words, are there extremely long lasting configurations in a melt which would affect ion transport in the glassy state A major effort during the past year has been to address these very fundamental questions. An important consideration here is to separate the effect of the variable melt structure from that of a variable cooling rate in the glass transformation range. For this reason our experiment consists of preparing 0.3 Na{sub 2}O--0.7 B{sub 2}O{sub 3} glasses from the melt which is first equilibrated at 1400 C and then annealed at 850 C for 0 to 180 minutes. From 850 C variously annealed melts are quenched to the glassy state by following identical procedure. If the structure (as reflected in ion transport) of 1400 C melt relaxes to that of 850 C in {approximately} minutes, we may expect to observe variations in the conductivity time in the ns range.

(Coal utilization in India)
Under the Phase II, Alternative Energy Resources Development (AERD) project of the United States Agency for International Development (USAID) and the Government of India (GOI), five collaborative coal projects have been initiated in the areas of: (1) NO{sub x}/SO{sub x} control from coal-fired power plants, (2) slagging combustor development for high-ash Indian coals, (3) characterization of Indian coals for combustion and gasification, (4) diagnostic studies for prediction of power plant life expectancy, and (5) environmental and natural resource analysis of coal cycle. The Pittsburgh Energy Technology Center (PETC) has the implementation responsibility for these projects. The Indian collaborative institutions identified for these projects are the Bharat Heavy Electricals Ltd. (BHEL), Trichy, (Projects 1--4), and the Tata Energy Research Institute (TERI) for Project 5. The Oak Ridge National Laboratory (ORNL) is providing cross-cut technical coordination and support for these five projects.

Spin motion of electrons in the SLC linac
It is generally expected that the depolarizing effects of the linear accelerator RF fields will be small. Recently Bill Atwood raised the question whether this conclusion is still correct in view of the fact that the particles in the SLC spend a larger fraction of their time at phase angles off crest'' due to BNS damping; since radial fields are in quadrature with the accelerating field this might imply that depolarizing effects are larger. On the other hand, because of the smaller emittance of the SLC relative to the earlier linac radial excursions would be smaller. The anticipation is therefore that the depolarizing effect will again be negligible but it might be worthwhile to update the early calculations of SLAC TN-63-97 revised. This paper discusses these updates.

The single antenna interferometer
Air and space borne platforms using synthetic aperture radars (SAR) have made interferometric measurements by using either two physical antennas mounted on one air-frame or two passes of one antenna over a scene. In this paper, a new interferometric technique using one pass of a single-antenna SAR system is proposed and demonstrated on data collected by the NASA-JPL AirSAR. Remotely sensed L-band microwave data are used to show the sensitivity of this technique to ocean surface features as well as a baseline for comparison with work by others using two-antenna systems. 7 refs., 3 figs.

Enchancing the use of coals by gas reburning-sorbent injection
The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO{sub x} is converted to N{sub 2}. The combustion process is completed by overfire air addition. SO{sub x} emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO{sub x} as solid sulfates that are collected in the particulate control device.
