A Comprehensive Study of Surface Chemistry for Application to Engine NOx Aftertreatment (open access)

A Comprehensive Study of Surface Chemistry for Application to Engine NOx Aftertreatment

This work focuses on developing a scientific understanding of the processes associated with NO{sub x} trap operation. NO{sub x} traps are the most advanced technology for achieving future emissions standards with diesel engines. Successful development of NO{sub x} traps will allow widespread use of diesel engines in light-duty vehicles, reducing oil imports by as much as 60%. Diesel engines have a high efficiency and low maintenance that makes them the ideal choice for transportation applications. Use of diesel engines in all light-duty vehicles would reduce oil consumption in the USA by 30% and oil imports by 60%, considerably improving our energy security. For heavy trucks, there is no viable alternative to diesel engines. Only diesel engines can provide the necessary high efficiency and long life. These benefits are offset by high emission of pollutants. Diesel engines have high emissions of NO{sub x} and particulate matter. Over the last 20 years, EPA has been reducing allowable emissions from diesel engines, and NO{sub x} emissions are scheduled to be cut by a factor of 10 over the next 7 years. The target NO{sub x} emissions for year 2010 is 0.20 g/hp-hr. This value is well below 1 g/hp-hr, which has been identified …

Recovering Spirituality - What 1 Corinthians Really Says About Being Spiritual

Lecture given Tuesday, February 19, 2002, 9:45 AM at Abilene Christian University: "A careful reading of 1 Corinthians reveals Paul's prescription for a church that had spirituality all wrong. We will see that being spiritual has little to do with knowledge and self, and everything to do with community."

Things Unseen: Three Key Questions for Churches of Christ in the New Millennium - Life: Can Churches of Christ Become Functionally Trinitarian?

Lecture given Tuesday, February 19, 2002, 8:30 AM at Abilene Christian University: "As the modern world recedes, Churches of Christ are finding their distinctive message and theology, which was rooted firmly in that world, less immediately convincing and more obviously deficient in the new cultural era we are entering. But this situation provides an opportunity to reclaim Christian truth that was compromised or even lost under the pressures and temptations of modernity. Three key questions focus this challenge for the church's heritage, life together and present message."

Results of the Excreta Bioassay Quality Control Program For April 1, 2006 Through March 31, 2007 (open access)

Results of the Excreta Bioassay Quality Control Program For April 1, 2006 Through March 31, 2007

A total of 66 urine samples, 6 blank fecal and 6 spiked artificial fecal samples were submitted during the report period (April 1, 2006 through March 31, 2007) to General Engineering Laboratories, South Carolina by the Hanford Internal Dosimetry Program (IDP) to check the accuracy, precision, and detection levels of their analyses. Urine analyses for tritium, Sr, 238Pu, 239Pu, 241Am, 243Am 235U, 238U, elemental uranium and fecal analyses for 241Am, 238Pu and 239Pu were tested this year. The number of QC urine samples submitted during the report period represented 1.7% of the total samples submitted. In addition to the samples provided by IDP, GEL was also required to conduct their own QC program, and submit the results of analyses to IDP. About 36% of the analyses processed by GEL during the second year of this contract were quality control samples. GEL tested the performance of 16 radioisotopes, all of which met or exceeded the specifications in the Statement of Work. IDP concluded that GEL was performing well for all analyses tested, and concerns identified earlier were satisfactorily resolved.

An Innovative Ceramic Corrosion Protection System for Zircaloy Cladding (open access)

An Innovative Ceramic Corrosion Protection System for Zircaloy Cladding

Light Water reactor (LWR) fuel performance is currently limited by thermal, chemical and mechanical constraints associated with the design, fabrication, and operation of the fuel in incore operation. Corrosion of the zirconium based (Zircaloy-4) alloy cladding of the fuel is a primary limiting factor. Recent success at the University of Florida in developing thin ceramic films with great adhesive properties for metal substrates offers an innovative breakthrough for eliminating a major weakness of the Zircaloy clad. ?The University of Florida proposes to coat the existing Zircaloy clad tubes with a ceramic coating for corrosion protection. An added bonus of this approach would be the implementation of a boron-containing burnable poison outer layer will also be demonstrated as part of the ceramic coating development. In this proposed effort, emphasis will be on the ceramic coating with only demonstration of feasibility on the burnable outer coating approach. This proposed program i s expected to give a step change (approximately a doubling) in clad lifetime before failure due to corrosion. In the development of ceramic coatings for Zircaloy-4 clad, silicon carbide and zirconium carbide coatings will first be applied to Zircaloy-4 coupons and cladding samples by thermal assisted chemical vapor deposition, plasma assisted …

Animal Identification: Overview and Issues

This report provides information about animal identification and proposed solutions. Livestock industry groups, animal health officials, and the U.S. Department of Agriculture (USDA) have been working to establish a nationwide identification (ID) system capable of quickly tracking animals from birth to slaughter, to deal with animal diseases and/or to satisfy foreign market specifications. Some consumer groups are among those who believe ID also would be useful for food safety or retail labeling purposes.

Evaluation of Mass Transfer Performance for Caustic-Side Solvent Extraction of Cesium in a Conventional 5-cm Centrifugal Contactor (open access)

Evaluation of Mass Transfer Performance for Caustic-Side Solvent Extraction of Cesium in a Conventional 5-cm Centrifugal Contactor

Tests have been conducted to determine if satisfactory mass transfer performance is achieved using a fully pumping 5-cm centrifugal contactor under conditions present in the Caustic-Side Solvent Extraction (CSSX) process. Tests utilized a commercially available contactor that had been modified by installation of a rotor housing bottom that had straight radial vanes on the process side. As received from the vendor, the housing bottom was equipped with curved (impeller-type) vanes that were intended to promote phase separation by minimizing mixing of influent solutions. Stage efficiencies exceeding 85% were obtained under conditions, present in the extraction section of the CSSX flowsheet. Under CSSX stripping conditions the stage efficiency exceeded 90%. In both cases, the efficiencies obtained exceed the minimum requirement for acceptable transfer of cesium in the CSSX process.
