Blanket Biological Review for General Maintenance Activities within Active Burial Grounds, 200 E and 200 W Areas, ECR No. 99-200-042 (open access)

Blanket Biological Review for General Maintenance Activities within Active Burial Grounds, 200 E and 200 W Areas, ECR No. 99-200-042

No plant and animal species protected under the Endangered Species Act, candidates for such protection, or species listed by the Washington state government were observed in the vicinity of the proposed sites. Piper's daisy is a Washington State Sensitive plant species, and as such is a Level III resource under the Hanford Site Biological Resources Management Plan. Compensatory mitigation is appropriate for this species when adverse impacts cannot be avoided. The stalked pod and crouching milkvetchs are relatively common throughout 200 West area, therefore even if the few individuals within the active burial grounds are disturbed, it is not likely that the overall local population will be adversely affected. The Watch List is the lowest level of listing for plant species of concern in the State of Washington. No adverse impacts to species or habitats of concern are expected to occur from routine maintenance within the active portions of the 218-W-4C, 218-W-4B, 218-W-3, 218-W-3A, a nd 218-W-5 burial grounds, as well as the portion of 218-E-12B currently used for storage of retired submarine reactor cores. The remaining portions of the 218-E-12B burial ground, the entire 218-E-10 burial ground, and the 218-W-6 burial ground currently have extensive vegetative cover and it …

Cooperative learning of neutron diffusion and transport theories (open access)

Cooperative learning of neutron diffusion and transport theories

A cooperative group instructional strategy is being used to teach a unit on neutron transport and diffusion theory in a first-year-graduate level, Reactor Theory course that was formerly presented in the traditional lecture/discussion style. Students are divided into groups of two or three for the duration of the unit. Class meetings are divided into traditional lecture/discussion segments punctuated by cooperative group exercises. The group exercises were designed to require the students to elaborate, summarize, or practice the material presented in the lecture/discussion segments. Both positive interdependence and individual accountability are fostered by adjusting individual grades on the unit exam by a factor dependent upon group achievement. Group collaboration was also encouraged on homework assignments by assigning each group a single grade on each assignment. The results of the unit exam have been above average in the two classes in which the cooperative group method was employed. In particular, the problem solving ability of the students has shown particular improvement. Further,the students felt that the cooperative group format was both more educationally effective and more enjoyable than the lecture/discussion format.

A DES ASIC Suitable for Network Encryption at 10 Gbps and Beyond (open access)

A DES ASIC Suitable for Network Encryption at 10 Gbps and Beyond

The Sandia National Laboratories (SNL) Data Encryption Standard (DES) Application Specific Integrated Circuit (ASIC) is the fastest known implementation of the DES algorithm as defined in the Federal Information Processing Standards (FIPS) Publication 46-2. DES is used for protecting data by cryptographic means. The SNL DES ASIC, over 10 times faster than other currently available DES chips, is a high-speed, filly pipelined implementation offering encryption, decryption, unique key input, or algorithm bypassing on each clock cycle. Operating beyond 105 MHz on 64 bit words, this device is capable of data throughputs greater than 6.7 Billion bits per second (tester limited). Simulations predict proper operation up to 9.28 Billion bits per second. In low frequency, low data rate applications, the ASIC consumes less that one milliwatt of power. The device has features for passing control signals synchronized to throughput data. Three SNL DES ASICS may be easily cascaded to provide the much greater security of triple-key, triple-DES.

Enhancement of Equilibrium Shift in Dehydrogenation Reactions Using a Novel Membrane Reactor Semi-Annual Report: October 1998-February 1999 (open access)

Enhancement of Equilibrium Shift in Dehydrogenation Reactions Using a Novel Membrane Reactor Semi-Annual Report: October 1998-February 1999

Using electroless deposition of palladium thin-films on a microporous ceramic substrate, we developed a hydrogen-selective palladium-ceramic composite membrane. The new membrane has significantly higher permeability and selectivity for hydrogen than many of the commercially available dense-metallic membrane. The hydrogen permeability of the new membrane increases with increasing temperature. These properties make it an ideal candidate for use in membrane reactors to study dehydrogenation reactions by equilibrium shift. To investigate the usefulness of the new membrane in membrane reactor-separator configuration, a model for studying dehydrogenation of cyclohexane by equilibrium in a membrane reactor is developed. Radial diffusion is considered to account for the concentration gradient in the radial direction due to permeation through the membrane. The model is investigated with and without the reaction. In the non-reaction case, a mixture of argon, benzene, cyclohexane, and hydrogen is used in the reaction side and argon is used in the separation side. In the case of dehydrogenation reaction, the feed stream to the reaction side contained hydrogen and argon while in the separation side argon is used as sweep gas. Equilibrium conversion for dehydrogenation of cyclohexane is 18.7%. Present study shows that 100% conversion can be achieved by equilibrium shift using Pd-Ceramic membrane …

An Evaluation of the Parallel Shift-and-Invert Lanczos Method (open access)

An Evaluation of the Parallel Shift-and-Invert Lanczos Method

When the Lanczos method is used to compute eigenvalues, it is often restarted or used with the shift-and-invert scheme. The restarted scheme usually uses less memory but the shift-and-invert scheme is more robust. In addition, the shift-and-invert Lanczos method requires accurate solutions of a series of linear systems. Parallel software packages suitable for these linear systems are only started to become available. In this talk, we will present our evaluation of two such packages and briefly examine when it is necessary to use the shift-and-invert scheme.

[Final report for DOE contract FG03-88ER13882]

The female reproductive organ, the gynoecium, is the most complex structure that plants produce. The molecular mechanisms that coordinate its development are unknown, but can be dissected by molecular genetics. The ettin (ett) mutation provides a remarkable window for viewing gynoecium development. ett induced alterations result from misinterpretation of positional information along longitudinal and transverse gynoecial axes. Molecular cloning revealed the ETT encoded amino acid sequence is homologous to transcriptional factors involved in signaling by the plant hormone auxin. Early ETT gene expression marks the site of the future outgrowth of the gynoecium. The primary gene sequence and pattern of expression of ETT fits with a role in hormone mediated signaling for regional development in the female organ.

FINAL TOPICAL REPORT FOR NOVEL SYSTEMS SEQUESTERING AND UTILIZATION OF CO2 (open access)

FINAL TOPICAL REPORT FOR NOVEL SYSTEMS SEQUESTERING AND UTILIZATION OF CO2

Atmospheric CO{sub 2} concentrations are increasing by about 0.5% each year, and there is serious concern that this will cause adverse climate change via the ''greenhouse effect.'' The principal sources of the increase are the utilization of fossil fuels and the deforestation of land. The capture of CO{sub 2} from flue gas or process streams has been demonstrated using chemical absorption with an ethanolamine solvent. However, the cost of releasing the CO{sub 2} by thermal stripping and recovering the solvent is very high, resulting in an energy penalty of 27% to 37 %, depending on the type of power plant (1). Alternatives that would result in energy penalties of 15% have been investigated. Sequestering schemes for CO{sub 2} produced from fossil fuels conversion to energy in utility plants could instead yield useful polymer products. Relatively concentrated CO{sub 2} by-product streams from fermentation of cellulose to fuel ethanol will also be available for conversion to useful polymers. As shown in Figure 1, this project offers two opportunities for mitigating the emission of CO{sub 2} to the atmosphere, depending on the source configuration and economic feasibility of the proposed processes: CO{sub 2} in a conventional utility-produced flue gas could be sequestered to …
