During the past year significant progress has been made in developing a commercial method of reducing the mobility of carbon dioxide in enhanced oil recovery processes. Four basic chemical structures, listed below, appear to show most promise for gas mobility control: (1) ethoxylated adducts of C/sub 8/ - C/sub 14/ linear alcohols; (2) sulfate esters of ethoxylated C/sub 9/ - C/sub 16/ linear alcohols; (3) low molecular weight co-polymers of ethylene oxide and propylene oxide; and (4) synthetic organic sulfonates. With the exception of the sulfonates, the above types are compatible with normal oil field brines, unaffected by the presence of crude oil and stable under conditions common in a petroleum reservoir. The second significant result during the year involves identification of several sulfonate structures that have high potential for mobility control for carbon dioxide. Commercial sulfonate additives are available that appear optimum for reservoirs where freshwater will be used to inject the surfactant solution. They can also be considered for limited brine applications, for as temperature increases the utility of sulfonates for mobility control also increases. This is encouraging since some of the previously identified additives are chemically unstable at temperatures encountered in most petroleum reservoirs. 113 references, 23 figures, 4 tables.</p>On Cratering: A Brief History, Analysis, and Theory of Cratering2018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1055595/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1055595/"><img alt="On Cratering: A Brief History, Analysis, and Theory of Cratering" title="On Cratering: A Brief History, Analysis, and Theory of Cratering" src="https://digital.library.unt.edu/ark:/67531/metadc1055595/small/"/></a></p><p>Cratering is a subject that has been studied by many investigators for many years for many purposes. These purposes range from experimental studies of physical properties to large scale excavations using explosive charges of kiloton size. In the past ten years considerable effort has been devoted to cratering experiments for the purposes of determining the effects of cratering by nuclear explosions, with recent accent on Plowshare applications. From the large amount of data available for craters in alluvian has been possible to establish very reliable relationships between charge size, depth of bursty crater radii, and crater depths. In addition it has been possible to construct a preliminary theory of the mechanics of explosive crater formation. The available experimental data for nuclear and high explosive craters are reviewed, with particular emphasis on the data for desert alluvium, and the pertinent relationships are derived. A theory of the important cratering mechanisms, which has been evolved on the basis of these data and data from other sources, is outlined.

A 6- ton/day plant was assumed, processing 1500 tons/year of uranium converter fuel at a burnup of 10,000 Mwd/ton and 270 tons/year of thorium converter fuel at a burnup of 20,000 Mwd/ton. Tanks of Savannah River design were assumed, with stainless steel construction for acid wastes and mild steel construction for neutralized wastes. The operating cycle of each tank was assumed to consist of equal filling and emptying periods plus a full (or dead) period. With interim storage time defined as filling time plus full time, tank costs were minimum when full time was 40 to 70% of the interim storage time, using present worth considerations. For waste storage times of 0.5 to 30 years, costs ranged from 2.2 x 10/sup -3/ to 9.5 x 10/sup -3/ mill/kwh/sub e/ for acid wastes and from 1.7 x 10/sup -3/ to 5.1 x 10/sup -3/ mill/kwh/sub e/ for neutralized wastes.

If annihilation occurs in a complex nucleus, protons, neutrons, and other nuclear fragments are also produced. The charge, number, and energy of the annihilation products are such that annihilation rocket engine concepts involving relatively low specific impulse (I/sub sp/ approx. = 1000 to 2000 s) and very high I/sub sp/ (3 x 10/sup 7/ s) appear feasible and have efficiencies on the order of 50% for annihilation energy to propulsion energy conversion. At I/sub sp/'s of around 15,000 s, however, it may be that only the kinetic energy of the charged nuclear fragments can be utilized for propulsion in engines of ordinary size. An estimate of this kinetic energy was made from known pieces of experimental and theoretical information. Its value is about 10% of the annihilation energy. Control over the mean penetration depth of protons into matter prior to annihilation is necessary so that annihilation occurs in the proper region within the engine. Control is possible by varying the antiproton kinetic energy to obtain a suitable annihilation cross section. The annihilation cross section at low energies is on the order of or larger than atomic areas due to a rearrangement reaction, but it is very low at high energy where its value is closer to nuclear areas.</p>Only source of energy2018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1055521/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1055521/"><img alt="Only source of energy" title="Only source of energy" src="https://digital.library.unt.edu/ark:/67531/metadc1055521/small/"/></a></p><p>Various plants that might play a role in the energy mix of the future are discussed and illustrated.

The units selected are representative of pre-NSPS design practices; tangential, wall, and cyclone fired. 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, at the superheater exit or into the ducting following the air heater. The sorbents trap SO{sub x} as solid sulfates and sulfites, which are collected in the particulate control device.</p>Evaluation of Wire Scanner for SM-12018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1056226/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1056226/"><img alt="Evaluation of Wire Scanner for SM-1" title="Evaluation of Wire Scanner for SM-1" src="https://digital.library.unt.edu/ark:/67531/metadc1056226/small/"/></a></p><p>Preliminary design concepts are presented for a wire scanner for experimentally evaluating spatial variations of neutron flux in the SM-l reactor core.

Critical temperatures were also to be measured. The samples were to be kept near 4 K between the irradiation and the measurement of critical properties. This work is directed toward establishing an engineering design fluence limit for Nb/sub 3/Sn when used in fusion reactor superconducting magnets.</p>Effects of Seismic Vibrations on the Experimental Gas-Cooled Reactor2018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1058908/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1058908/"><img alt="Effects of Seismic Vibrations on the Experimental Gas-Cooled Reactor" title="Effects of Seismic Vibrations on the Experimental Gas-Cooled Reactor" src="https://digital.library.unt.edu/ark:/67531/metadc1058908/small/"/></a></p><p>The effects of seismic vibrations on the dynamic behavior of a composite system were analyzed. The equations of motion were derived and soIved with special emphasis on determining the resulting stresses. The method of analysis thus developed was applied to the composite structure consisting of the core, pressure vessel, and supporting skirt of the Experimental Gas-Cooled Reactor (EGCR). A system with three degrees of freedom was considered in order to determine the effects of an earthquake of the maximum intensity expected in the area surrounding Oak Ridge, Tennessee. The system of equations of motion was solved both numerically and analytically, and the resonant frequencies were determined. The seismic effect was shown to be small when the frequency of the seismic disturbance coincided with a natural frequency of the system. In particular, the shear stresses in the graphite core were shown to be negligible.

Within each box and folder are photos, letters, scrapbooks and artifacts. Individually they are curiosities, but combined, they are interconnected evidence of the past. The Byrd Williams Family Photography Collection was created by four photographers, all named Byrd Moore Williams, over four successive generations beginning in 1890 and continuing through the present day. The collection is proof of four lives, lived in vivid detail. The story is yet to be told.; The archive, acquired by UNT Libraries in 2014, contains over 300,000 unique images, ranging from snapshots to studio portraits to street photography. Subject matter is diverse too; in this collection the landscapes of Yosemite site alongside televangelists, professional hockey players and Fort Worth city landmarks new and old. The history of the Williams Family is told within the collection through letters, postcards, diaries and artifacts such as cameras and significant personal effects." Also on the banner are several examples of photos found in the archive collection.</p>33.210127 -97.149003[Byrd Williams Timeline Banner displayed at exhibit]2017-11-11T21:26:02-06:00https://digital.library.unt.edu/ark:/67531/metadc1039238/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1039238/"><img alt="[Byrd Williams Timeline Banner displayed at exhibit]" title="[Byrd Williams Timeline Banner displayed at exhibit]" src="https://digital.library.unt.edu/ark:/67531/metadc1039238/small/"/></a></p><p>Photograph of a banner displayed at the "Proof: The Byrd Williams Family Photography Archive".

His early prints were developed in a darkroom in the family's home. His work includes stunningly detailed images of his hardware store, photos of family members and places around Gainesville.; Byrd Moore Williams, Jr.; Byrd Williams II studied at the University of Texas (1905-1907), worked as an engineer, and expanded on family tradition by incorporating imagery in forms other than portraiture, which included landscapes and city scenery. His work includes documentation of civil engineering projects including the San Antonio River Walk. Byrd II's surveying equipment and notebooks are included in the collection as well as fragile nitrate based negatives featuring early scenes of Yosemite National Park.; Byrd Williams III; Byrd Williams III explored photography on his own terms as a fine art as well as a commercial enterprise. He owned a photo service in Fort Worth and in the 1930s created an expansive series of women at work. Through his images, he documented street scenes and the people of Fort Worth, which was developing rapidly in the mid-20th century. With the work of Byrd Williams III, we see photography develop into a unique way of making a personal statement.; Byrd Williams IV; Byrd Williams IV is a prolific exhibiting photographer, who has shown in the United States and abroad. His work is situated in our modern world, however it has significant historical weight. Although three previous generations of photographers are in his DNA, his vision is uniquely his own: humane, curious and full of life. Byrd IV is the last remaining photographer in his family lineage.

Based on previous capacitor designs of 3 KJ, 5 KJ and 10 KJ, the final Nova 12.5 KJ capacitor evolved. At the outset of the Nova capacitor development program, a relatively new dielectric system, polypropylene-paper-DOP, seemed to show superiority in volumetric efficiency, life, and more importantly cost. However, as a result of studies performed at Maxwell, a high-density, energy-storage capacitor was developed utilizing new high-quality, high-density paper and caster oil as the dielectric. Test data have demonstrated that the Maxwell 12.5 KJ capacitor exceeds all LLNL's qualification requirements.</p>Diamond-turning tool setting by interferogram analysis2018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1057388/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1057388/"><img alt="Diamond-turning tool setting by interferogram analysis" title="Diamond-turning tool setting by interferogram analysis" src="https://digital.library.unt.edu/ark:/67531/metadc1057388/small/"/></a></p><p>A method was developed to establish a numerically controlled tool path with respect to the work spindle centerline.

The application reported is for an f/2 concave spherical mirror.</p>Addition of bromine as a diagnostic gas to inertial confinement fusion target microspheres2018-01-22T07:23:21-06:00https://digital.library.unt.edu/ark:/67531/metadc1053493/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1053493/"><img alt="Addition of bromine as a diagnostic gas to inertial confinement fusion target microspheres" title="Addition of bromine as a diagnostic gas to inertial confinement fusion target microspheres" src="https://digital.library.unt.edu/ark:/67531/metadc1053493/small/"/></a></p><p>Currently, direct fuel rho r measurements on Inertial Confinement Fusion (ICF) targets by neutron activation of the argon tracer gas mixed with the DT fuel would require a 100 fold increase in neutron yield. Bromine, on the other hand, has excellent properties for neutron activation analysis at neutron yields of 10two' to 10/sup 8/, when present at an internal pressure of from 0.1 to 0.2 atmospheres. Bromine addition is accomplished in a 2 furnace system using the dried-gel method of microsphere production. An upper furnace operated at 1500/sup 0/C is separated from a lower furnace by a cooled zone. The lower furnace is filled with bromine gas and operated at approximately 1250/sup 0/C. The upper furnace is the glass production furnace. The cooled zone in between the upper and lower furnace is to prevent the hot bromine gas from rising into the upper furnace. The microspheres pass through the cooled zone and immediately into the 1250/sup 0/C bromine furnace where the bromine permeates into the spheres.</p>
