U.S. Economic Sanctions Through 1996

Description: Since the early 1960s, the United States has imposed a range of economic sanctions on Cuba, the most prominent of which is a comprehensive embargo prohibiting trade with Cuba. This Congressional Research Service report first provides an overview of U.S.-Cuba relations and U.S. policy toward Cuba. It then examines the history and current legislative and executive authorities of the various components of U.S. sanctions against Cuba, including aid, trade, and other restrictions.

Automating Pro/Engineer Using Trail Files and External Programs

Description: Keyboard macros provide shortcuts to many repetitive command sequences in Pro/Engineer. They map any number of frequently used command sequences to user-selected keyboard keys. They may be nested within each other and may also include user keyboard entry within the macro. Another powerful feature of Pro/Engineer is adding menu options. Menu options may be added to any Pro/Engineer menu and is an effective way to graphically display keyboard macros to make them more accessible. Command sequences… more

Systems and economic analysis of microalgae ponds for conversion of CO{sub 2} to biomass. Final report

Description: There is growing evidence that global warming could become a major global environmental threat during the 21st century. The precautionary principle commands preventive action, at both national and international levels, to minimize this potential threat. Many near-term, relatively inexpensive, mitigation options are available. In addition, long-term research is required to evaluate and develop advanced, possibly more expensive, countermeasures, in the eventuality that they may be required. The u… more

Grazing Fees: An Overview

Description: This report briefly discusses charging fees for grazing private livestock on federal lands, which is a long-standing but contentious practice. Generally, livestock producers who use federal lands want to keep fees low, while conservation groups and others believe fees should be raised to approximate "fair market value."

Special report on the audit of the management of Department of Energy construction projects

Description: DOE`s FY 1996 budget of $18 billion included $1.1 billion for construction projects; ensuring that these projects meet bonafide existing or future DOE needs becomes increasingly important as DOE`s missions evolve and its organization changes. In 1994 and 1995, IG issued several reports expressing concerns about the construction planning process and questioned whether planned construction was necessary to meet mission needs. The reports also pointed out that DOE did not ensure that originally id… more

Consequence analysis of an unmitigated NaOH solution spray release during addition to waste tank

Description: Toxicological consequences were calculated for a postulated maximum caustic soda (NaOH) solution spray leak during addition to a waste tank to adjust tank pH. Although onsite risk guidelines were exceeded for the unmitigated release, site boundary consequences were below the level of concern. Means of mitigating the release so as to greatly reduce the onsite consequences were recommended.

The development of coal-based technologies for Department of Defense facilities. Semiannual technical progress report, March 28, 1995--September 27, 1995

Description: The U.S. Department of Defense (DOD), through the Interagency Agreement with the U.S. Department of Energy (DOE), has initiated a three-phase program with the Consortium for Coal-Water Mixture Technology, with the aim of decreasing DOD`s reliance on imported oil by increasing its use of coal. The program is being conducted as a cooperative agreement between the Consortium and DOE. Activities this reporting period are summarized by phase. During this reporting period, preparation of the Phase I … more

Catch tank inhibitor addition 200-East and 200-West Areas

Description: Reported is the study of 11 catch tanks in the 200-East Area and the 7 catch tanks in the 200-West Area listed as active. The location, capacity, material of construction, annual total accumulation, annual rain intrusion, waste transfer rate, and access for chemical injection in these tanks are documented. The present and future utilization and isolation plans for the catch tanks are established.

First positron annihilation lifetime measurement of Pu

Description: We have made the first measurement of defects in an aged sample of {delta} phase, Ga stabilized Pu, using positron annihilation lifetime spectroscopy. This measurement validates the procedure necessary to perform measurements on this highly toxic material and obtain data representative of sample conditions. Comparison of the positron annihilation lifetime analysis of the data with calculated values suggests that He filled vacancies or vacancy clusters dominate the defect population. Such defect… more

Compact tokamak reactors part 2 (numerical results)

Description: The authors describe a numerical optimization scheme for fusion reactors. The particular application described is to find the smallest copper coil spherical tokamak, although the numerical scheme is sufficiently general to allow many other problems to be solved. The solution to the steady state energy balance is found by first selecting the fixed variables. The range of all remaining variables is then selected, except for the temperature. Within the specified ranges, the temperature which satis… more

Final report for tank 241-AN-102, grab samples 2AN-95-1 through 2AN-95-6 and 102-AN-1 through 102-AN-4

Description: Ten grab samples (2AN-95-1, 2, 3, 4A, 5A; 102-AN-1, 2, 3(A), 3(B), and 4) and one field blank (2AN-95-6) were taken from tank 241-AN-102. In support of the safety screening program, total organic carbon and cyanide were performed as secondary analyses because the differential scanning calorimetry results exceeded the notification limit. These were compared to safety screening limits at a confidence level of 95%. Waste compatibility analyses were performed on the 3 supernate samples and the fiel… more

Improvement of storage, handling, and transportability of fine coal. Quarterly technical progress report No. 5, January 1, 1995--March 31, 1995

Description: The Mulled Coal process was developed as a means of overcoming the adverse handling characteristics of wet fine coal without thermal drying. The process involves the addition of a low cost, harmless reagent to wet fine coal using off-the-shelf mixing equipment. Based on laboratory- and bench-scale testing, Mulled Coal can be stored, shipped, and burned without causing any of the plugging, pasting, carryback and freezing problems normally associated with wet coal. The objectives of this project … more

Synthesis and study of conjugated polymers containing Di- or Triphenylamine

Description: This thesis consists of two separate parts. The first part addresses the synthesis and study of conjugated polymers containing di- or triphenylamine. Two types of polymers: linear polymers and dendrimers, were synthesized. The polymers were characterized by NMR, IR, UV, GPC, TGA and DSC. Electronic and optical properties of the polymers were studied through the conductivity measurements and excitation- emission spectra. the second part of this thesis deals with a reaction of electron-rich acety… more

Desalination with carbon aerogel electrodes

Description: An electrically regenerated electrosorption process known as carbon aerogel CDI was developed for continuously removing ionic impurities from aqueous streams. A salt solution flows in a channel formed by pairs of parallel carbon aerogel electrodes. Each electrode has a very high BET surface area and very low resistivity. After polarization, anions and cations are removed from electrolyte by the electric field and electrosorbed onto the carbon aerogel. The solution is thus separated into two str… more
