The Forest Service sells some timber at prices that are less than the agency costs to administer the timber program. This report discusses these "below-cost" timber sales that have been debated by Congress for more than a decade, but no policy to address the issue has been adopted legislatively or administratively.

The PI of this research program came to Cornell University from Hannover (Germany) in July 1987. Beginning in Fall 1987 a new research group and a new research facilities were built up at Cornell. The program {open_quotes}Defects and Transport in Mixed Oxides{close_quotes} was started in July 1988. The last progress report for this program was written on September 30, 1993 and submitted to DOE with the last renewal proposal. Significant progress has been made in the areas of: (i) the nonstoichiometry of quasi-binary spinels, (ii) the cation tracer diffusion in oxide solid solutions of the type (Fe,Me){sub 3{minus}{delta}}O{sub 4}, (iii) the Monte-Carlo simulation of the cation diffusion in spinel solid solutions, (iv) interdiffusion measurements in the spinel solution (Fe,Mn){sub 3{minus}{delta}}O{sub 4}, and (v) defect-related properties of Co{sub 1{minus}{delta}}O.

This plan describes how the Multi-Function Waste Tank Facility (MWTF) Project conducts reviews of design media; describes actions required by Project participants; and provides the methodology to ensure that the design is complete, meets the technical baseline of the Project, is operable and maintainable, and is constructable. Project W-236A is an integrated project wherein the relationship between the operating contractor and architect-engineer is somewhat different than that of a conventional project. Working together, Westinghouse Hanford Company (WHC) and ICF Karser Hanford (ICF KH) have developed a relationship whereby ICF KH performs extensive design reviews and design verification. WHC actively participates in over-the-shoulder reviews during design development, performs a final review of the completed design, and conducts a formal design review of the Safety Class I, ASME boiler and Pressure Vessel Code items in accordance with WHC-CM-6-1, Standard Engineering Practices.

Nodular defects in multi-layer dielectric coatings have been computer modeled to characterize the electro-mechanical responses to laser pulses with wavelengths of 1.06 {mu}m and pulse lengths between 1 and 20 ns. The simulation begins with an axisymmetric electric field model using AMOS, a full-wave Maxwell solver with lossy (dispersive) electric and magnetic material models. Electric fields calculated by this code determine the spatial distribution of absorbed laser energy in the vicinity of the nodule. This data is linked to a thermal/stress model and mechanical calculations are executed using the general purpose finite element code COSMOS/M. The simulation estimates the transient temperature response of the nodule and the surrounding medium and predicts the dynamic stresses caused by the thermal impulse. This integrated computer process has been exercised to characterize failure of nodules as a function of defect characteristics, including seed size and depth.

The new post-Cold War world and the role of the United States will be shaped by action on a wide variety of foreign policy and defense issues. The 104th Congress will debate many of these issues and help determine the outcome as it considers the National Security Act proposed by House Republicans in the Contract with America and takes up bills on foreign policy and defense agencies, programs, and budgets.

This report presents performance data for a Parting Lathe, which has been submitted in response to a LANL specification for a piece of machine equipment. The performance data was accepted by LANL as meeting the requirements of the specification.

The space radiation environment for the CLEMENTINE I mission was investigated using a new calculational model, CHIME, which includes the effects of galactic cosmic rays (GCR), anomalous component (AC) species and solar energetic particle (SEP) events and their variations as a function of time. Unlike most previous radiation environment models, CHIME is based upon physical theory and is {open_quotes}calibrated{close_quotes} with energetic particle measurements made over the last two decades. Thus, CHIME provides an advance in the accuracy of estimating the interplanetary radiation environment. Using this model we have calculated particle energy spectra, fluences and linear energy transfer (LET) spectra for all three major components of the CLEMENTINE I mission during 1994: (1) the spacecraft in lunar orbit, (2) the spacecraft during asteroid flyby, and (3) the interstate adapter USA in Earth orbit. Our investigations indicate that during 1994 the level of solar modulation, which dominates the variation in the GCR and AC flux as a function of time, will be decreasing toward solar minimum levels. Consequently the GCR and AC flux will be increasing during Y, the year and, potentially, will rise to levels seen during previous solar minimums. The estimated radiation environment also indicates that the AC will dominate …

This position paper recommends changes to improve the interface between the Cross-Site Transfer System (Project W-058) and the Multi-Function Waste Tank Facility (Project W-236A) to handle planned waste retrieval and storage operations. Appendix A includes cost estimates and schedule impacts for each project. The cost estimates, schedule impacts, and this position paper will be the basis for writing a change request to formally implement these changes on Project W-236A and Project W-058/W-028. Recommendations are made on pipeline rerouting, pump and configuration, and flushing configuration.

Calculations of indirect drive Inertial Confinement Fusion target experiments require an integrated approach in which laser irradiation and radiation transport in the hohlraum are solved simultaneously with the symmetry, implosion and burn of the fuel capsule. The Implicit Monte Carlo method has proved to be a valuable tool for the two dimensional radiation transport within the hohlraum, but the impact of statistical noise on the symmetric implosion of the small fuel capsule is difficult to overcome. We present an angular biasing technique in which an increased number of low weight photons are directed at the imploding capsule. For typical parameters this reduces the required computer time for an integrated calculation by a factor of 10. An additional factor of 5 can also be achieved by directing even smaller weight photons at the polar regions of the capsule where small mass zones are most sensitive to statistical noise.

This report describes results of assessment of the risk of emissions of hazardous air pollutants at one of the electric power stations, Bailly Station, which is also the site of a Clean Coal Technology project demonstrating the Pure Air Advanced Flue Gas Desulfurization process (wet limestone). This station represents the configuration of no NO{sub x} reduction, particulate control with electrostatic precipitators, and SO{sub 2} control with a wet scrubber. The test was conducted September 3--6, 1993. Sixteen trace metals were determined along with 5 major metals. Other inorganic substances and organic compounds were also determined.

In shipbuilding and many other industries, copper weld backing bars are used to draw the heat out of the weld. The problem that some users of these bars encounter is that these bars, on occasion, actually melt in spots and become welded to the weld plates. After this happens a number of times, the backing bar becomes so degraded that it must be either discarded or machined, both of which are very costly and time-consuming actions. To avoid this fusion between the backing bar and the weld plate, the weld processes that are used cannot be ones of high beat input. This requirement is very limiting when thick plates are being welded. The plates must be beveled, and more weld passes must be run. These problems are also costly and time consuming. The aim of this project is to find a way to produce backing bars with nearly the same `chilling` effect but with both a greater resistance to molten metal and resistance to arcing to the backing bar itself. A possible solution currently being tested is to coat the copper bars with a thin layer of a ceramic coating. The procedure used was to coat the copper bars with …

In the July 19, 1988, Federal Register [52 FR 27290] the Environmental Protection Agency (EPA) issued a final rule that conditionally exempted waste samples used in small-scale treatability studies from regulation under Subtitle C of the Resource Conservation and Recovery Act (RCRA). The final rule was intended to promote the development of new technologies for the treatment of hazardous wastes. However, in order to minimize danger to human health and the environment, it also imposed limitations and conditions on the amount of wastes that may be exempted from RCRA Subtitle C regulations for use in treatability studies. On July 7, 1993, EPA proposed amendments to the existing regulations that would increase the quantity limits for certain types of waste. In addition, EPA proposed to extend the period of time for which laboratories may conduct treatability studies involving bioremediation technologies from 1 year to 2 years. This bulletin summarizes the provisions of the revised rule.

A practical method for performing self-consistent electronic structure calculations based upon full-potential multiple-scattering theory is presented. Solutions to the single site Schroedinger equation are obtained by solving coupled channel integral equations for a potential which is analytically continued out to the circumscribing sphere. This potential coincides with the full cell potential inside each atomic cell. Scattering matrices and wavefunctions for the full cell potential are obtained from surface Wronskian relations. The charge density is obtained from the single particle Green`s function. This Green`s function is computed using the cell scattering matrices and wavefunctions using the layer multiple scattering theory. Self consistent solutions require a solution at each iteration to the Poisson equation. The Poisson equation is solved using a variational cellular method. In the approach a local solution to each cell is augmented by adding a series of regular harmonics (solutions to Laplace`s equation). Minimizing the coulomb energy, subject to continuity of the potential across all cell boundary provides an expression for the coefficients of the regular harmonics. This method is applied to BCC Nb. Calculated properties converge well in angular momentum and show comparable accuracy to full potential linearized muffin-tin orbital calculations.

This report is on The issue for 18 mahogany species is whether any qualifies for regulation under the Convention on International Trade in Endangered Species (CITES). (1) Pessimists on this issue say "yes," while optimists see the abundance of species in parts of their range and therefore say "no." Both camps question the accuracy of data supplied by the other side. Both agree that the presence of mahogany trees may provide local governments with an incentive to retain rain forests, especially since mahogany cultivation has not been particularly successful.
