Expanding Threat Reduction and Nonproliferation Programs: Concepts and Definitions

The report of the 9/11 Commission called for continued support for threat reduction assistance. H.R. 10, the 9/11 Recommendations Implementation Act, calls for a review of U.S. policy in this area. President Bush, Members of Congress, and analysts outside government have suggested that the United States provide threat reduction and nonproliferation assistance to nations outside the former Soviet Union.

Pakistan's Domestic Political Developments (open access)

Pakistan's Domestic Political Developments

Pakistan is a strategically important country and home to one of the world’s largest Muslim populations. In October 1999, Pakistan’s Chief of Army Staff Gen. Pervez Musharraf replaced Prime Minister Nawaz Sharif in a bloodless coup. In the wake of the military overthrow of the elected government, Islamabad faced considerable international opprobrium and was subjected to automatic coup-related U.S. sanctions. The September 2001 terrorist attacks on the United States and Musharraf’s ensuing withdrawal of support for the Afghan Taliban regime, however, had the effect of greatly reducing Pakistan’s international isolation. Congress removed restrictions, and large-scale U.S. aid to the country resumed, in the final months of 2001. The United States views Pakistan as a vital ally in the international anti-terrorism coalition. The Bush Administration has refrained from expressing any significant public criticisms of Pakistan’s internal political practices, while still asserting that the strengthening of civilian political institutions in Islamabad is “a requirement for the development of a stable, moderate Islamic state.”

9/11 Terrorism: Global Economic Costs (open access)

9/11 Terrorism: Global Economic Costs

The 9/11 attacks were part of Al Qaeda’s strategy to disrupt Western economies and impose both direct and secondary costs on the United States and other nations. The immediate costs were the physical damage, loss of lives and earnings, slower world economic growth, and capital losses on stock markets. Indirect costs include higher insurance and shipping fees, diversion of time and resources away from enhancing productivity to protecting and insuring property, public loss of confidence, and reduced demand for travel and tourism. In a broader sense, the 9/11 attacks led to the invasions and occupations of Afghanistan and Iraq (and the Global War on Terrorism) and perhaps emboldened terrorists to attack in Bali, Spain, Morocco, and Saudi Arabia. A policy question for Congress is how to evaluate the costs and benefits of further spending to counter terrorism and its economic impact.

IRRADIATION EFFECTS ON THE PHYSICAL CHARACTERISTICS OF SEWAGE SLUDGE

The radiation effects on the physical characteristic of the sewage sludge were studied in order to obtain information which will be used for study on the enhancement of the sludge's dewaterability. Water contents, capillary suction time, zeta potential, irradiation dose, sludge acidity, total solid concentration, sludge particle size and microbiology before and after irradiation were investigated. Irradiation gave an effect on physical characteristics sludge. Water content in sludge cake could be reduced by irradiation at the dose of 10kGy.

Acceleressence: Dark energy from a phase transition at the seesawscale (open access)

Acceleressence: Dark energy from a phase transition at the seesawscale

Simple models are constructed for ''acceleressence'' dark energy: the latent heat of a phase transition occurring in a hidden sector governed by the seesaw mass scale v{sup 2}/M{sub Pl}, where v is the electroweak scale and M{sub Pl} the gravitational mass scale. In our models, the seesaw scale is stabilized by supersymmetry, implying that the LHC must discover superpartners with a spectrum that reflects a low scale of fundamental supersymmetry breaking. Newtonian gravity may be modified by effects arising from the exchange of fields in the acceleressence sector whose Compton wavelengths are typically of order the millimeter scale. There are two classes of models. In the first class the universe is presently in a metastable vacuum and will continue to inflate until tunneling processes eventually induce a first order transition. In the simplest such model, the range of the new force is bounded to be larger than 25 {micro}m in the absence of fine-tuning of parameters, and for couplings of order unity it is expected to be {approx} 100 {micro}m. In the second class of models thermal effects maintain the present vacuum energy of the universe, but on further cooling, the universe will ''soon'' smoothly relax to a matter dominated …

The effect of thin film thickness on the incorporation of Mn interstitials in Ga{sub 1-x}Mn{sub x}As (open access)

The effect of thin film thickness on the incorporation of Mn interstitials in Ga{sub 1-x}Mn{sub x}As

We have investigated the effect of film thickness on the distribution of Mn atoms at various lattice sites in Ga{sub 1-x}Mn{sub x}As thin films. We find that the growth surface acts as a sink facilitating the out-diffusion of Mn interstitials (Mn{sub I}), and thus reducing its concentration in the film. The out-diffused Mn{sub I} accumulate on the surface in a surface oxide layer and do not participate in the ferromagnetism of the film. For thin films less than 15 nm thick, no Mn{sub I} can be detected. Because of the absence of compensating Mn{sub I} defects, higher T{sub C} can be achieved for such extremely thin Ga{sub 1-x}Mn{sub x}As layers. These results agree with our previously suggested Fermi-level-governed upper limit of the T{sub C} of III-Mn-V ferromagnetic semiconductors.

Method for Making a Uranium Chloride Salt Product (open access)

Method for Making a Uranium Chloride Salt Product

The subject apparatus provides a means to produce UCl3, in large quantities without incurring corrosion of the containment vessel or associated apparatus. Gaseous Cl is injected into a lower layer of Cd where CdCl2 is formed. Due to is lower density, the CdCl2 rises through the Cd layer into a layer of molten LiCl-KCL salt where a rotatable basket containing uranium ingots is suspended. The CdCl2 reacts with the uranium to form UCl, and Cd. Due to density differences, the Cd sinks down to the liquid Cd layer and is reused. The UCl3 combines with the molten salt. During production the temperature is maintained at about 600 degrees C. while after the uranium has been depleted the salt temperature is lowered, the molten salt is pressure siphoned from the vessel, and the salt product LiCl-KCl-30 mol% UCl3 is solidified.

Stress Corrosion Cracking Model for High Level Radioactive-Waste Packages (open access)

Stress Corrosion Cracking Model for High Level Radioactive-Waste Packages

A stress corrosion cracking (SCC) model has been adapted for performance prediction of high level radioactive-waste packages to be emplaced in the proposed Yucca Mountain repository. For waste packages of the proposed Yucca Mountain repository, the outer barrier material is the highly corrosion-resistant Alloy UNS-N06022 (Alloy 22), the environment is represented by aqueous brine films present on the surface of the waste package from dripping or deliquescence of soluble salts present in any surface deposits, and the tensile stress is principally from weld induced residual stress. SCC has historically been separated into ''initiation'' and ''propagation'' phases. Initiation of SCC will not occur on a smooth surface if the surface stress is below a threshold value defined as the threshold stress. Cracks can also initiate at and propagate from flaws (or defects) resulting from manufacturing processes (such as welding); or that develop from corrosion processes such as pitting or dissolution of inclusions. To account for crack propagation, the slip dissolution/film rupture (SDFR) model is adopted to provide mathematical formulae for prediction of the crack growth rate. Once the crack growth rate at an initiated SCC is determined, it can be used by the performance assessment to determine the time to through-wall …
