Autonomous microexplosives subsurface tracing system final report.
The objective of the autonomous micro-explosive subsurface tracing system is to image the location and geometry of hydraulically induced fractures in subsurface petroleum reservoirs. This system is based on the insertion of a swarm of autonomous micro-explosive packages during the fracturing process, with subsequent triggering of the energetic material to create an array of micro-seismic sources that can be detected and analyzed using existing seismic receiver arrays and analysis software. The project included investigations of energetic mixtures, triggering systems, package size and shape, and seismic output. Given the current absence of any technology capable of such high resolution mapping of subsurface structures, this technology has the potential for major impact on petroleum industry, which spends approximately $1 billion dollar per year on hydraulic fracturing operations in the United States alone.

Blue Heron Paper Company: Oregon Mill Uses Model-Based Energy Assessment to Identify Energy and Cost Savings Opportunities (Revision)
Blue Heron Paper Company conducted a model-based energy assessment (MEA) to determine how to reduce effluent flow and heat load, minimize fresh water, and reduce process energy use at the company's Oregon City, Oregon, paper mill. Assessment staff recommended 15 projects, 7 of which the company considered. These projects would save an estimated 608,161 million British thermal units per year in natural gas and 990 kilowatt hours per year in electricity. Corresponding annual cost savings would be about $2.9 million per year. Furthermore, by reducing fuel requirements for the plant steam system, Blue Heron would also reduce stack gas emissions.

Blue sensors : technology and cooperative monitoring in UN peacekeeping.
For over a half-century, the soldiers and civilians deployed to conflict areas in UN peacekeeping operations have monitored ceasefires and peace agreements of many types with varying degrees of effectiveness. Though there has been a significant evolution of peacekeeping, especially in the 1990s, with many new monitoring functions, the UN has yet to incorporate monitoring technologies into its operations in a systematic fashion. Rather, the level of technology depends largely on the contributing nations and the individual field commanders. In most missions, sensor technology has not been used at all. So the UN has not been able to fully benefit from the sensor technology revolution that has seen effectiveness greatly amplified and costs plummet. This paper argues that monitoring technologies need not replace the human factor, which is essential for confidence building in conflict areas, but they can make peacekeepers more effective, more knowledgeable and safer. Airborne, ground and underground sensors can allow peacekeepers to do better monitoring over larger areas, in rugged terrain, at night (when most infractions occur) and in adverse weather conditions. Technology also allows new ways to share gathered information with the parties to create confidence and, hence, better pre-conditions for peace. In the future sensors …

Breakdown of Hot-Spot model in determining convective amplification in large homogeneous systems
Convective amplification in large homogeneous systems is studied, both analytically and numerically, in the case of a linear diffraction-free stochastic amplifier. Overall amplification does not result from successive amplifications in small scale high intensity hot-spots, but from a single amplification in a delocalized mode of the driver field spreading over the whole interaction length. For this model, the hot-spot approach is found to systematically underestimate the gain factor by more than 50%.

Build up of electron cloud with different bunch pattern in the presence of solenoidal field
We have augmented the code POSINST to include solenoid fields, and used it to simulate the build up of electron cloud due to electron multipacting in the PEP-II positron ring. We find that the distribution of electrons is strongly affected by the resonances associated with the cyclotron period and bunch spacing. In addition, we discover a threshold beyond which the electron density grows exponentially until it reaches the space charge limit. The threshold does not depend on the bunch spacing but does depend on the positron bunch population.

Calculation of Phonon Density of States for Alpha-U
Phonon density of states for {alpha}-U was calculated with the linear response theory and the RSPFLAPW (fully relativistic full potential spin-polarized linearized-augmented-plane-wave) method. It has been used for studying the temperature dependence of the specific heat of uranium. It was shown that the details of the phonon DOS are not very important for the specific heat, and practically the same results can be obtained with Debye model.

Calibration of Initial Measurements from the Full Aperture Backscatter system on NIF
The Full Aperture Backscatter System (FABS) provides a measure of the spectral power, and integrated energy scattered by stimulated Brillouin (348-354 nm) and Raman (400 - 700 nm) scattering into the final focusing lens of the first four beams of the NIF laser. The system was designed to provide measurements at the highest expected fluences with: (1) spectral and temporal resolution, (2) beam aperture averaging, and (3) near-field imaging. This is accomplished with a strongly attenuating diffusive fiber coupler and streaked spectrometer and separate calibrated time integrated spectrometers, and imaging cameras. Measurement of the wavelength dependent sensitivity of the complete system is accomplished with a calibrated Xe lamp. Data from the calibration system is combined with experimental data to produce the power and energy measurements. Examples of measurements will be discussed.

Carbon Dioxide Capture From Flue Gas Using Dry Regenerable Sorbents Quarterly Technical Progress Report: January-March 2004
This report describes research conducted between January 1, 2004 and March 31, 2004 on the use of dry regenerable sorbents for removal of carbon dioxide from flue gas. RTI has produced laboratory scale batches (approximately 300 grams) of supported sorbents (composed of 20 to 40% sodium carbonate) with high surface area and acceptable activity. Initial rates of weight gain of the supported sorbents when exposed to a simulated flue gas exceeded that of 100% calcined sodium bicarbonate. One of these sorbents was tested through six cycles of carbonation/calcination by thermogravimetric analysis and found to have consistent carbonation activity. Kinetic modeling of the regeneration cycle on the basis of diffusion resistance at the particle surface is impractical, because the evolving gases have an identical composition to those assumed for the bulk fluidization gas. A kinetic model of the reaction has been developed on the basis of bulk motion of water and carbon dioxide at the particle surface (as opposed to control by gas diffusion). The model will be used to define the operating conditions in future laboratory- and pilot-scale testing.

Carbon Dioxide Sequestration by Mechanochemical Carbonation of Mineral Silicates
The University of Utah and the University of Idaho investigated the carbonation of silicate minerals by mechanochemical processing. This method uses intense grinding, and has the potential of being much less expensive than other methods of mineral sequestration. Tests were conducted in three types of grinding devices. In these tests, natural and synthetic silicate compounds were ground for varying times in the presence of gaseous CO{sub 2}. A significant change takes place in the lizardite variety of serpentine after 15 to 20 minutes of intense grinding in the presence of gaseous CO{sub 2}. The X-ray diffraction spectrum of lizardite thus treated was much different than that of the untreated mineral. This spectrum could not be identified as that of any natural or synthetic material. Laboratory analyses showed that small amounts of carbon are fixed by grinding lizardite, forsterite, and wollastonite (all naturally-occurring minerals), and synthetic magnesium silicate, in the presence of gaseous CO{sub 2}. It was thus concluded that further investigation was warranted, and a follow-up proposal was submitted to the Department of Energy under solicitation number.

Carbon Sequestration in Reclaimed Mined Soils of Ohio
This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites were characterized by distinct age chronosequences of reclaimed minesoil and were located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites are owned and maintained by Americal Electrical Power. These sites were reclaimed (1) with topsoil application, and (2) without topsoil application, and were under continuous grass or forest cover. Three core and three bulk soil samples were collected from each of the experimental site and one unmined site (UMS) for 0-15 cm and 15-30 cm depths and soil bulk density ({rho}{sub b}), texture, saturated hydraulic conductivity (Ks), volumes of transport (VTP) and storage (VSP) pores, available water capacity (AWC), pH and electrical conductivity (EC), SOC, total nitrogen (TN) concentrations and stocks were determined. The preliminary results from sites reclaimed with topsoil and grass indicate that sand content was highest (24%) and clay content was lowest (17%) for site reclaimed in 2003 (R03) for 0-15 cm depth. The {rho}{sub b} was highest for R03 (1.24 Mg m{sup -3}) than sites reclaimed in 1987 (R87; 1.02 Mg m{sup -3}), 1978 (R78; 0.98 Mg m{sup -3}) and UMS (0.96 …

Cellulose and the Control of Growth Anisotropy
The authors research aims to understand morphogenesis, focusing on growth anisotropy, a process that is crucial to make organs with specific and heritable shapes. For the award, the specific aims were to test hypotheses concerning how growth anisotropy is controlled by cell wall structure, particularly by the synthesis and alignment of cellulose microfibrils, the predominant mechanical element in the cell wall. This research has involved characterizing the basic physiology of anisotropic expansion, including measuring it at high resolution; and second, characterizing the relationship between growth anisotropy, and cellulose microfibrils. Important in this relationship and also to the control of anisotropic expansion are structures just inside the plasma membrane called cortical microtubules, and the research has also investigated their contribution to controlling anisotropy and microfibril alignment. In addition to primary experimental papers, I have also developed improved methods relating to these objectives as well as written relevant reviews. Major accomplishments in each area will now be described.
