ENSO Simulation in Coupled Ocean-Atmosphere Models: Are the Current Models Better?

Description: Maintaining a multi-model database over a generation or more of model development provides an important framework for assessing model improvement. Using control integrations, we compare the simulation of the El Nino/Southern Oscillation (ENSO), and its extratropical impact, in models developed for the 2007 Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report with models developed in the late 1990's (the so-called Coupled Model Intercomparison Project-2 [CMIP2] models). The … more

Incident Energy Dependence of pt Correlations at RHIC

Description: We present results for two-particle transverse momentum correlations, ({Delta}p{sub t,i}{Delta}p{sub t,j}), as a function of event centrality for Au+Au collisions at {radical}s{sub NN} = 20, 62, 130, and 200 GeV at the Relativistic Heavy Ion Collider. We observe correlations decreasing with centrality that are similar at all four incident energies. The correlations multiplied by the multiplicity density increase with incident energy and the centrality dependence may show evidence of processes s… more

Russian Military and Security Forces: A Postulated Reaction to a Nuclear Detonation

Description: In this paper, we will examine how Russia's military and security forces might react to the detonation of a 10-kiloton nuclear weapon placed next to the walls surrounding the Kremlin. At the time of this 'big bang,' Putin is situated outside Moscow and survives the explosion. No one claims responsibility for the detonation. No other information is known. Numerous variables will determine how events ultimately unfold and how the military and security forces will respond. Prior to examining these… more

MIDWEST REGIONAL CARBON SEQUESTRATION PARTNERSHIP (MRCSP) MANAGING CLIMATE CHANGE AND SECURING A FUTURE FOR THE MIDWEST'S INDUSTRIAL BASE

Description: This is the third semiannual report for Phase I of the Midwest Carbon Sequestration Partnership (MRCSP). The project consists of nine tasks to be conducted over a two-year period that started in October 2003. The makeup of the MRCSP and objectives are described. Progress on each of the active Tasks is also described and where possible, for those Tasks at some point of completion, a summary of results is presented.

Automobile and Light Truck Fuel Economy: The CAFE Standards

Description: An issue over the years has been the inaccurate rulemaking to carry out fuel economy ratings and the in-use fuel economy has failed to meet the rated fuel economy. Various amendments and acts are being passed to ensure the accuracy to the fuel economy readings and take other factors into account when measuring them.

PRODUCTION IMPROVEMENT FROM INCREASED PERMEABILITY USING ENGINEERED BIOCHEMICAL SECONDARY RECOVERY METHODOLOGY IN MARGINAL WELLS OF THE EAST TEXAS FIELD

Description: A combination of a regenerating biochemical mixture and an organic surfactant has been applied to wells in the East Texas Field with the goal of restoring permeability, reversing formation damage, mobilizing hydrocarbons, and ultimately increasing production. Initial work in task 1 was designed to open the perforations and remove blockages of scale, asphaltene, and other corrosion debris. This was accomplished on three wells that produce from the Woodbine, and was necessary to prepare the wells… more

Resolving the tips of the tree of life: How much mitochondrialdata doe we need?

Description: Mitochondrial (mt) DNA sequences are used extensively to reconstruct evolutionary relationships among recently diverged animals,and have constituted the most widely used markers for species- and generic-level relationships for the last decade or more. However, most studies to date have employed relatively small portions of the mt-genome. In contrast, complete mt-genomes primarily have been used to investigate deep divergences, including several studies of the amount of mt sequence necessary to … more

Status of Current Plutonium Evaluations And an Update Plan for ENDL99

Description: We review the current state of ENDL99, ENDF/B-VI.r8, JENDL-3.3, JEFF-3.0 and ENDF/B-VII.{beta}0 plutonium evaluations and lay out a tentative plan for updating all of the ENDL99 plutonium evaluations. In some specific cases, an evaluation for a particular isotope is of sufficient quality for us to adopt in ENDL99. More often, the quality of all evaluations for an isotope are low enough that we will need to perform a new evaluation.

An Indirect Route for Ethanol Production

Description: The ZeaChem indirect method is a radically new approach to producing fuel ethanol from renewable resources. Sugar and syngas processing platforms are combined in a novel way that allows all fractions of biomass feedstocks (e.g. carbohydrates, lignins, etc.) to contribute their energy directly into the ethanol product via fermentation and hydrogen based chemical process technologies. The goals of this project were: (1) Collect engineering data necessary for scale-up of the indirect route for eth… more

The Distribution and Flux of Fish in the Forebay of The Dalles Dam in 2003

Description: In spring and summer 2003, the Pacific Northwest National Laboratory led a team that conducted mobile and fixed hydroacoustic surveys in the forebay of The Dalles Dam for the U.S. Army Corps of Engineers - Portland District, for the Anadromous Fish Evaluation Program. The surveys provided information on the distribution and movement of smolt-sized fish relative to ambient factors such as flow, bathymetry, or diel cycle in the forebay at The Dalles Dam. This information is intended to provide ba… more

Calcium Carbonate Production by Coccolithophorid Algae in Long Term, Carbon Dioxide Sequestration

Description: Predictions of increasing levels of anthropogenic carbon dioxide (CO{sub 2}) and the specter of global warming have intensified research efforts to identify ways to sequester carbon. A number of novel avenues of research are being considered, including bioprocessing methods to promote and accelerate biosequestration of CO{sub 2} from the environment through the growth of organisms such as coccolithophorids, which are capable of sequestering CO{sub 2} relatively permanently. Calcium and magnesiu… more

Entrainment of Solvent in Aqueous Stream from CINC V-5 Contactor

Description: Personnel completed a rapid study of organic entrainment during operation of a CINC V-5 contactor under prototypical conditions covering the range of expected MCU operation. The study only considered the entrainment of organic into the strip acid effluent destined for the Defense Waste Processing Facility. Based on this work, the following observations are noted: (1) Concentrations of total organic from the contactor discharge, based upon modifier measurements, in the acid typically averaged 33… more

Study of X-ray photoionized Fe plasma and comparisons with astrophysical modeling codes

Description: The charge state distributions of Fe, Na and F are determined in a photoionized laboratory plasma using high resolution x-ray spectroscopy. Independent measurements of the density and radiation flux indicate the ionization parameter {zeta} in the plasma reaches values {zeta} = 20-25 erg cm s{sup -1} under near steady-state conditions. A curve-of-growth analysis, which includes the effects of velocity gradients in a one-dimensional expanding plasma, fits the observed line opacities. Absorption l… more

Small-Scale Performance Testing for Studying New Explosives

Description: The development of new high-explosive (HE) formulations involves characterizing their safety and performance. Small-scale experiments requiring only a small amount of explosives are of interest because they can facilitate development while minimizing hazards and reducing cost. A detonation-spreading, dent test, called the Floret test, was designed to obtain performance data for new explosives. It utilizes the detonation of about a 1.0 g sample of HE, initiated by an accelerated aluminum flyer. … more
