Development of the Write Process for Pipeline-Ready Heavy Oil

Work completed under this program advances the goal of demonstrating Western Research Institute's (WRI's) WRITE{trademark} process for upgrading heavy oil at field scale. MEG Energy Corporation (MEG) located in Calgary, Alberta, Canada supported efforts at WRI to develop the WRITE{trademark} process as an oil sands, field-upgrading technology through this Task 51 Jointly Sponsored Research project. The project consisted of 6 tasks: (1) optimization of the distillate recovery unit (DRU), (2) demonstration and design of a continuous coker, (3) conceptual design and cost estimate for a commercial facility, (4) design of a WRITE{trademark} pilot plant, (5) hydrotreating studies, and (6) establish a petroleum analysis laboratory. WRITE{trademark} is a heavy oil and bitumen upgrading process that produces residuum-free, pipeline ready oil from heavy material with undiluted density and viscosity that exceed prevailing pipeline specifications. WRITE{trademark} uses two processing stages to achieve low and high temperature conversion of heavy oil or bitumen. The first stage DRU operates at mild thermal cracking conditions, yielding a light overhead product and a heavy residuum or bottoms material. These bottoms flow to the second stage continuous coker that operates at severe pyrolysis conditions, yielding light pyrolyzate and coke. The combined pyrolyzate and mildly cracked overhead streams form …

Applications of Lagrangian Dispersion Modeling to the Analysis of Changes in the Specific Absorption of Elemental Carbon (open access)

Applications of Lagrangian Dispersion Modeling to the Analysis of Changes in the Specific Absorption of Elemental Carbon

We use a Lagrangian dispersion model driven by a mesoscale model with four-dimensional data assimilation to simulate the dispersion of elemental carbon (EC) over a region encompassing Mexico City and its surroundings, the study domain for the 2006 MAX-MEX experiment, which was a component of the MILAGRO campaign. The results are used to identify periods when biomass burning was likely to have had a significant impact on the concentrations of elemental carbon at two sites, T1 and T2, downwind of the city, and when emissions from the Mexico City Metropolitan Area (MCMA) were likely to have been more important. They are also used to estimate the median ages of EC affecting the specific absorption of light, aABS, at 870 nm as well as to identify periods when the urban plume from the MCMA was likely to have been advected over T1 and T2. Values of aABS at T1, the nearer of the two sites to Mexico City, were smaller at night and increased rapidly after mid-morning, peaking in the mid-afternoon. The behavior is attributed to the coating of aerosols with substances such as sulfate or organic carbon during daylight hours, but such coating appears to be limited or absent at …

B, D and K Decays (open access)

B, D and K Decays

The present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC. The aim of Working Group 2 was twofold: on one hand, to provide a coherent, up-to-date picture of the status of flavor physics before the start of the LHC; on the other hand, to initiate activities on the path towards integrating information on NP …

Conformal Supersymmetry Breaking and Dynamical Tuningof the Cosmological Constant (open access)

Conformal Supersymmetry Breaking and Dynamical Tuningof the Cosmological Constant

We propose 'conformal supersymmetry breaking' models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale. The both scales are originated from the constant term in the superpotential through the common source of the R-symmetry breaking. We show that dynamical tuning between those mass scales significantly reduces the degree of fine-tuning necessary for generating the almost vanishing cosmological constant.

Defense Acquisitions: 2009 Is a Critical Juncture for the Army's Future Combat System

A letter report issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) program--which comprises 14 integrated weapon systems and an advanced information network--is the centerpiece of the Army's effort to transition to a lighter, more agile, and more capable combat force. The substantial technical challenges, the Army's acquisition strategy, and the cost of the program are among the reasons why the program is recognized as needing special oversight and review. Section 211 of the National Defense Authorization Act for Fiscal Year 2006 requires GAO to report annually on the FCS program. This report includes an examination of (1) how the definition, development, and demonstration of FCS capabilities are proceeding, particularly in light of the go/no-go decision scheduled for 2009; (2) the Army's plans for making production commitments for FCS and any risks related to the completion of development; and (3) the estimated costs for developing and producing FCS."

Defense Acquisitions: Significant Challenges Ahead in Developing and Demonstrating Future Combat System's Network and Software

A letter report issued by the Government Accountability Office with an abstract that begins "The Army's Future Combat System (FCS) requires a software-based advanced information network to meld people, sensors, and weapons into a cohesive fighting force. As software controls 95 percent of FCS's functionality, it determines the success or failure of the program. The Army contracted with the Boeing Company as a lead systems integrator (LSI) to define, develop and integrate FCS, including software development. GAO must by law report annually on FCS. This is one of two reports to meet this requirement. It addresses risks facing the development of network and software, the practices being used to manage software, and the timing of key network demonstrations. In conducting our work, GAO has contacted numerous DOD, Army, and contractor offices; reviewed technical documents on software and network development and plans; attended meetings; and spoken to Army and other officials on various aspects of FCS network and software development. GAO also performed detailed work at five FCS software developers."

An Implicit "Drift-Lorentz" Particle Mover for Plasma and Beam Simulations (open access)

An Implicit "Drift-Lorentz" Particle Mover for Plasma and Beam Simulations

In order to efficiently perform particle simulations in systems with widely varying magnetization, we have developed a 'drift-Lorentz mover', which interpolates between full particle dynamics and drift kinetics in such a way as to preserve a physically correct gyroradius and particle drifts for both large and small ratios of the timestep to the cyclotron period. In order to extend applicability of the mover to systems with plasma frequency exceeding the cyclotron frequency - such as one may have with fully neutralized drift compression of a heavy ion beam - we have developed an implicit version of the mover. A first step in this direction, in which the polarization charge was added to the field solver, was described previously. Here we describe a fully implicit algorithm (which is analogous to the direct-implicit method for conventional particle-in-cell simulation), a stability analysis of it, its implementation in the WARP code, and several tests of the resultant code. The fully implemented version is electrostatic; we are beginning development of an electromagnetic version, and describe also the status of that effort.

International Trade: U.S. Trade Preference Programs Provide Important Benefits, but a More Integrated Approach Would Better Ensure Programs Meet Shared Goals

A letter report issued by the Government Accountability Office with an abstract that begins "U.S. trade preference programs promote economic development in poorer nations by providing export opportunities. The Generalized System of Preferences, Caribbean Basin Initiative, Andean Trade Preference Act, and African Growth and Opportunity Act unilaterally reduce U.S. tariffs for many products from over 130 countries. However, three of these programs expire partially or in full this year, and Congress is exploring options as it considers renewal. GAO was asked to review the programs' effects on the United States and on foreign beneficiaries' exports and development, identify policy trade-offs concerning these programs, and evaluate the overall U.S. approach to preference programs. To address these objectives, we analyzed trade data, reviewed trade literature and program documents, interviewed U.S. officials, and did fieldwork in six countries."

Military Training: Compliance with Environmental Laws Affects Some Training Activities, but DOD Has Not Made a Sound Business Case for Additional Environmental Exemptions

A letter report issued by the Government Accountability Office with an abstract that begins "A fundamental principle of military readiness is that the military must train as it intends to fight, and military training ranges allow the Department of Defense (DOD) to accomplish this goal. According to DOD officials, heightened focus on the application of environmental statutes has affected the use of its training areas. Since 2003, DOD has obtained exemptions from three environmental laws and has sought exemptions from three others. This report discusses the impact, if any, of (1) environmental laws on DOD's training activities and military readiness, (2) DOD's use of statutory exemptions from environmental laws on training activities, (3) DOD's use of statutory exemptions on the environment, and (4) the extent to which DOD has demonstrated the need for additional exemptions. To address these objectives, GAO visited 17 training locations; analyzed environmental impact and readiness reports; and met with officials at service headquarters, the Office of the Secretary of Defense, federal regulatory agencies, and nongovernmental environmental groups."
