Africa and the War on Terrorism
African countries overwhelmingly expressed their support for the U.S.-led efforts on the war against terrorism shortly after the September 11 attacks on New York and Washington. Some African countries are reportedly sharing intelligence and are coordinating with Washington to fight terrorism in Africa. Administration officials believe that Africa is a potential breeding ground for terrorism. Some African officials are concerned that despite the strong support African governments have provided to the anti-terror campaign, they are not seen as real coalition partners in the fight against terrorism. African officials note that cooperation between the United States and Africa in the fight against terrorism should also include extraditing and apprehending members of African terrorist and extremist groups active in Europe and the United States. They argue that these groups are raising funds and organizing in the west, often unhindered by western governments.

China and the World Trade Organization
China has sought over the past several years to become a member of the World Trade Organization (WTO), the international agency that administers multilateral trade rules. China’s WTO membership (as well as that of Taiwan’s) was formally approved at the WTO Ministerial Conference in Doha, Qatar in November 2001. On December 11, 2001, China officially became a WTO member. WTO membership will require China to significantly liberalize its trade and investment regimes, which could produce significant new commercial opportunities for U.S. businesses. A main concern for Congress is to ensure that China fully complies with its WTO commitments.

Development of a Waste Treatment Process to Deactivate Reactive Uranium Metal and Produce a Stable Waste Form
This paper highlights the results of initial investigations conducted to support the development of an integrated treatment process to convert pyrophoric metallic uranium wastes to a non-pyrophoric waste that is acceptable for land disposal. Several dissolution systems were evaluated to determine their suitability to dissolve uranium metal and that yield a final waste form containing uranium specie(s) amenable to precipitation, stabilization, adsorption, or ion exchange. During initial studies, one gram aliquots of uranium metal or the uranium alloy U-2%Mo were treated with 5 to 60 mL of selected reagents. Treatment systems screened included acids, acid mixtures, and bases with and without addition of oxidants. Reagents used included hydrochloric, sulfuric, nitric, and phosphoric acids, sodium hypochlorite, sodium hydroxide and hydrogen peroxide. Complete dissolution of the uranium turnings was achieved with the H{sub 3}PO{sub 4}/HCI system at room temperature within minutes. The sodium hydroxide/hydrogen peroxide, and sodium hypochlorite systems achieved complete dissolution but required elevated temperatures and longer reaction times. A ranking system based on criteria, such as corrosiveness, temperature, dissolution time, off-gas type and amount, and liquid to solid ratio, was designed to determine the treatment systems that should be developed further for a full-scale process. The highest-ranking systems, nitric acid/sulfuric …

Effect of the location of Mn sites in ferromagnetic GaMnAs on its Curie temperature
We report a strong correlation between the location of Mn sites in ferromagnetic Ga{sub 1-x}Mn{sub x}As measured by channeling Rutherford backscattering and by particle induced x-ray emission experiments and its Curie temperature. The concentrations of free holes determined by electrochemical capacitance-voltage profiling and of uncompensated Mn{sup ++} spins determined from SQUID magnetization measurements are found to depend on the concentration of unstable defects involving highly mobile Mn interstitials. This leads to large variations in T{sub c} of Ga{sub 1-x}Mn{sub x}As when it is annealed at different temperatures in a narrow temperature range. The fact that annealing under various conditions has failed to produce Curie temperatures above {approx}110K is attributed to the existence of an upper limit on the free hole concentration in low-temperature-grown Ga{sub 1-x}Mn{sub x}As.

Engineered Antibodies for Monitoring of Polynuclear Aromatic Hydrocarbons
This project was undertaken to fill needs in ODE's human and ecosystem health effects research, site remediation, rapid emergency response, and regulatory compliance monitoring programs. Doe has greatly stimulated development and validation of antibody-based, rapid, field-portable detection systems for small hazardous compounds. These range from simple dipsticks, microplate enzyme-linked immunosorbent assays (ELISAs), and hand-held colorimeters, to ultrasensitive microfluidic reactors, fiber-optic sensors and microarrays that can identify multiple analytes from patterns of cross-reactivity. Unfortunately, the technology to produce antibodies with the most desirable properties did not keep pace. Lack of antibodies remains a limiting factor in production and practical use of such devices. The goals of our project were to determine the chemical and structural bases for the antibody-analyte binding interactions using advanced computational chemistry, and to use this information to create useful new binding properties through in vitro genetic engineering and combinatorial library methods.

Evaluation of the location and recency of faulting near prospective surface facilities in Midway Valley, Nye County, Nevada
Evaluation of surface faulting that may pose a hazard to prospective surface facilities is an important element of the tectonic studies for the potential Yucca Mountain high-level radioactive waste repository in southwestern Nevada. For this purpose, a program of detailed geologic mapping and trenching was done to obtain surface and near-surface geologic data that are essential for determining the location and recency of faults at a prospective surface-facilities site located east of Exile Hill in Midway Valley, near the eastern base of Yucca Mountain. The dominant tectonic features in the Midway Valley area are the north- to northeast-trending, west-dipping normal faults that bound the Midway Valley structural block-the Bow Ridge fault on the west side of Exile Hill and the Paint-brush Canyon fault on the east side of the valley. Trenching of Quaternary sediments has exposed evidence of displacements, which demonstrate that these block-bounding faults repeatedly ruptured the surface during the middle to late Quaternary. Geologic mapping, subsurface borehole and geophysical data, and the results of trenching activities indicate the presence of north- to northeast-trending faults and northwest-trending faults in Tertiary volcanic rocks beneath alluvial and colluvial sediments near the prospective surface-facilities site. North to northeast-trending faults include the Exile …

Extending the Internet Tax Moratorium and Related Issues
The Internet Tax Freedom Act, enacted in 1998, placed a 3-year moratorium on the ability of state and local governments 1) to impose new taxes on Internet access or 2) to impose multiple or discriminatory taxes on electronic commerce. It grandfathered existing taxes on Internet access. The original moratorium expired on October 21, 2001. Numerous bills to extend the moratorium were introduced in the first session of the 107th Congress. The Congress approved H.R. 1552 (P.L. 107-75, enacted November 28, 2001) which extended the prior moratorium by 2 years, until November 1, 2003.

Feature Subset Selection by Estimation of Distribution Algorithms
This paper describes the application of four evolutionary algorithms to the identification of feature subsets for classification problems. Besides a simple GA, the paper considers three estimation of distribution algorithms (EDAs): a compact GA, an extended compact GA, and the Bayesian Optimization Algorithm. The objective is to determine if the EDAs present advantages over the simple GA in terms of accuracy or speed in this problem. The experiments used a Naive Bayes classifier and public-domain and artificial data sets. In contrast with previous studies, we did not find evidence to support or reject the use of EDAs for this problem.

Fission Multiplicity Detection With Temporal Gamma-Neutron Discrimination From Higher Order Time Correlation Statistics
The subject of this thesis is the nondestructive assay (NDA) of nuclear materials. NDA is made possible by the fact that fissile and fertile transuranic isotopes emit characteristic radiations. Fission Multiplicity Detection (FMD) is the name of the standard technique used in NDA of nuclear materials in the 1960s and 1970s. It was characterized by the use of fast plastic scintillating detectors. These systems were used in both active and passive mode. These FMD systems were eventually replaced by thermal well counters as the standard NDA technique. The thermal well counters use {sup 3}He detectors embedded in a moderator. Among the passive neutron assay techniques, neutron multiplicity counting (NMC) in a thermal well counter is the preferred technique for the determination of fissile mass when spontaneous fission yields are significant. it is used in conjunction with gamma-ray spectroscopy to determine the isotopic composition of a sample. The major problem with the use of fast plastic detectors as used in FMD is that both neutrons and gamma rays are detected. The pulses from the two are indistinguishable. The disadvantages of this indistinguishability between neutron and gamma rays is explained further in the explanation of NMIS multiplicity in Section 2.5.
