A 20-year data set of surface longwave fluxes in the Arctic

Description: Creation of 20-year data set of surface infrared fluxes from satellite measurements. A reliable estimate of the surface downwelling longwave radiation flux (DLF) is a glaring void in available forcing data sets for models of Arctic sea ice and ocean circulation. We have developed a new method to estimate the DLF from a combination of satellite sounder retrievals and brightness temperatures from the TIROS Operational Vertical Sounder (TOVS), which has flown on NOAA polar-orbiting satellites cont… more

2010 Census: Cost and Design Issues Need to Be Addressed Soon

Description: A letter report issued by the General Accounting Office with an abstract that begins "The key to a successful census is meticulous planning as it helps ensure greater cost-effectiveness. However, the 2000 and previous censuses have been marked by poor planning, which unnecessarily raised the costs and risks of those efforts. GAO was asked to (1) review the U.S. Census Bureau's (Bureau) current plans for 2010 and whether they might address shortcomings of the 2000 Census, (2) analyze the Bureau'… more

Accessing High Pressure States Relevant to Core Conditions in the Giant Planets

Description: We have designed an experimental technique to use on the National Ignition Facility (NIF) laser to achieve very high pressure (P{sub max} > 10 Mbar = 1000 GPa), dense states of matter at moderate temperatures (kT < 0.5 eV = 6000 K), relevant to the core conditions of the giant planets. A discussion of the conditions in the interiors of the giant planets is given, and an experimental design that can approach those conditions is described.

Acquisition of time-lapse, 6-component, P- and S-wave, crosswell seismic survey with orbital vibrator and of time-lapse VSP for CO2 injection monitoring

Description: Using an orbital vibrator source (2-components), and a 40 level 3-component geophone string, a 6-component crosswell survey was acquired before and after a CO2 injection in a saline aquifer. Decomposition of the two source components and component rotation of both source and sensors created good separation of P- and S-wave energy allowing independent analysis of travel time and reflectivity. A time-lapse VSP was also acquired.

Aging, tumor suppression and cancer: High-wire act!

Description: Evolutionary theory holds that aging is a consequence of the declining force of natural selection with age. We discuss here the evidence that among the causes of aging in complex multicellular organisms, such as mammals, is the antagonistically pleiotropic effects of the cellular responses that protect the organism from cancer. Cancer is relatively rare in young mammals, owing in large measure to the activity of tumor suppressor mechanisms. These mechanisms either protect the genome from damage… more

Alternative Conceptual Model for Colloid Generation from Commercial Spent Nuclear Fuel

Description: Colloids have the potential to transport strongly sorbing radionuclide contaminants in soils and groundwater aquifers. Recent studies from the Nevada Test Site have indicated the enhanced mobility plutonium, albeit in minute quantities, associated with various silicate minerals (Kersting et al., 1999); however, significant colloidal transport of thorium (Th) and rare earths (RE) in nature, considered to be chemical analogs for plutonium, is rare. Yet, the current Yucca Mountain model for colloi… more

ANALYSIS OF TWO-PHASE FLOW MODELS WITH TWO MOMENTUM EQUATIONS.

Description: An analysis of the standard system of differential equations describing multi-speed flows of multi-phase media is performed. It is proved that the Cauchy problem, as posed in most best-estimate thermal-hydraulic codes, results in unstable solutions and potentially unreliable description of many physical phenomena. A system of equations, free from instability effects, is developed allowing more rigorous numerical modeling.

Analytic Expressions for the Angular Resolution of Compton Gamma-ray Detectors

Description: This paper describes the derivation of analytic expressions for the angular resolution of reconstructing gamma rays detected via Compton interactions. We consider two types of gamma-ray detectors: Compton-ring and electron-tracking devices. In Compton-ring devices, the direction of the scattered electron is not resolved, only the total energy (electron and scattered photon) and the scattered photon direction are measured. The measured quantities define a cone about the axis of the scattered pho… more

Anisotropic Flow at RHIC.

Description: We present the first measurement of directed flow (v{sub 1}) at the Relativistic Heavy Ion Collider (RHIC). v{sub 1} is found to be consistent with zero at pseudorapidities {eta} from -1.2 to 1.2, then rises to the level of a couple of percent over the range 2.4 < |{eta}| < 4. The latter observation is similar to that from NA49 if the SPS rapidities are shifted by the difference in beam rapidity between RHIC and SPS. We studied the evolution of elliptic flow from p + p collisions through … more

Assessment of Various Kinetic Models for the Pyrolysis of a Microgranular Cellulose

Description: The kinetics of pyrolysis of a micro-crystalline cellulose in nitrogen were studied from TGA and DTG data, obtained with two different modes of heating: a dynamic mode at constant heating rates between 1 and 11 C/min and an isothermal mode at various temperatures, kept constant between 280 and 320 C. In isothermal mode, it appeared very clearly that the mass depletion shows a sigmoid profile characteristic of an auto-accelerated reaction process. This behavior is consistent with kinetics of nuc… more
