Abortion: Judicial Control

Description: In 1973 the U.S. Supreme Court held that the Constitution protects a woman's decision whether or not to terminate her pregnancy, Roe v. Wade, 410 U.S. 113, and that a State may not unduly burden the exercise of that fundamental right by regulations that prohibit or substantially limit access to the means of effectuating that decision, Doe v. Bolton, 410 U.S. 179. But rather than settling the issue, the Court's rulings have kindled heated debate and precipitated a variety of governmental actions… more

Abortion: Legislative Control

Description: In 1973, the U.S. Supreme Court held that the Constitution protects a woman's decision whether or not to terminate her pregnancy (Roe v. Wade), and that a State may not unduly burden the exercise of that fundamental right by regulations that prohibit or substantially limit access to the means of effectuating that decision (Doe v. Bolton). However, the issue of a woman's right to an abortion is far from settled. This report discusses the various legislative actions undertaken since 1973 to eithe… more

Accelerating structure with linear excitation

Description: The switched power linac (SPL) structures require a ring-shaped laser beam pulse of uniform intensity to avoid transverse field components of the accelerating field at the center. In order to also utilize the reflection of the outgoing EM wave, the switching element has to be very close to the outer edge of the structure to ensure nearly synchronous superposition at the beam hole with the original inward going wave. It is sometimes easier to produce linear (flat) laser beams, e.g., from powerfu… more

Advanced Vortexing Combustor (VC) for space/water heating applications (proof-of-concept model development)

Description: The Naval Civil Engineering Laboratory is developing a proof-of-concept Vortexing Combustor (VC) with 2--4 MMBtu/hr firing capacity to bum both coal-water fuel and ultrafine coal for boiler applications. Thermodynamic analysis was made to trade off design features of the combustor. Results indicated that for best thermal efficiency, consistent with the low temperature combustion requirements, a sub-adiabatic VC arrangement should be selected. In order to minimize the risk of uncertainties, a th… more

Ambient ground motion measurements at Argonne National Laboratory over extended time periods

Description: Successful operation of the APS facility requires a very stable particle beam. Vibration coupled through mechanical systems, such as magnet supports, beam tube supports, and other paths can cause deterioration of the particle beam. There are two sources of vibration: external, or far field, which is generated external to the APS site and internal, or near field, which is generated on site and associated with operation of the facility. Internal vibration sources can be controlled or minimized us… more

Analysis of corrosion data for carbon steels in simulated salt repository brines and acid chloride solutions at high temperatures

Description: Carbon steel is currently the leading candidate material for fabrication of a container for isolation of high level nuclear waste in a salt repository. Since brine entrapped in the bedded salt can migrate to the container by several transport processes, corrosion is an important consideration in the long-term performance of the waste package. A detailed literature search was performed to compile relevant corrosion data for carbon steels in anoxic acid chloride solutions, and simulated salt repo… more

Anomalous rf magnetoresistance in copper at 4/degree/K

Description: We have measured the effect of a magnetic field on the surface resistance of polycrystalline Cu at f = 1.2 GHz and at 4.4/degree/K; under these conditions the surface resistance is well into the anomalous skin effect regime but has not reached its limiting value. We find that the transverse and longitudinal magnetoresistance are an order of magnitude smaller than the DC magnetoresistance and depend quadratically on the field. At low fields we observe a decrease in surface resistance with increa… more

Application of the TEMPEST computer code to canister-filling heat transfer problems

Description: Pacific Northwest Laboratory (PNL) researchers used the TEMPEST computer code to simulate thermal cooldown behavior of nuclear waste glass after it was poured into steel canisters for long-term storage. The objective of this work was to determine the accuracy and applicability of the TEMPEST code when used to compute canister thermal histories. First, experimental data were obtained to provide the basis for comparing TEMPEST-generated predictions. Five canisters were instrumented with appropria… more

Argon spill test for E706

Description: There were three different tests involved in this series. It should be stated that the purpose of the test was to determine if there should be extra precautions taken with the calorimeter vent stack. No attempt was made to do quantitative measurements. The three types of tests were diffusion tests, spills at a remote site, and a spill at the MW building. Oxygen monitors used were the standard Energy Saver type throughout. 6 figs.

An assessment of the state of the art in predicting the failure of ceramics: Final report

Description: The greatest weakness in existing design strategies for brittle fracture is in the narrow range of conditions for which the strategies are adequate. The primary reason for this weakness is the use of simplistic mechanical models of fracture processes and unverified statistical models of materials. To improve the design methodology, the models must first be improved. Specifically recommended research goals are: to develop models of cracks with realistic geometry under arbitrary stress states; to… more

Bootstrap current in TFTR (Tokamak Fusion Test Reactor)

Description: Neutral-beam-heated plasmas in TFTR show evidence of substantial non-ohmically-driven toroidal current, even for balanced beam momentum input. The observations are inconsistent with calculations including only ohmic and beam-driven currents, and presently can only be matched by models including the neoclassical bootstrap current. 28 refs., 9 figs., 1 tab.
