Electron Charged Graphite-based Hydrogen Storage Material (open access)

Electron Charged Graphite-based Hydrogen Storage Material

The electron-charge effects have been demonstrated to enhance hydrogen storage capacity using materials which have inherent hydrogen storage capacities. A charge control agent (CCA) or a charge transfer agent (CTA) was applied to the hydrogen storage material to reduce internal discharge between particles in a Sievert volumetric test device. GTI has tested the device under (1) electrostatic charge mode; (2) ultra-capacitor mode; and (3) metal-hydride mode. GTI has also analyzed the charge distribution on storage materials. The charge control agent and charge transfer agent are needed to prevent internal charge leaks so that the hydrogen atoms can stay on the storage material. GTI has analyzed the hydrogen fueling tank structure, which contains an air or liquid heat exchange framework. The cooling structure is needed for hydrogen fueling/releasing. We found that the cooling structure could be used as electron-charged electrodes, which will exhibit a very uniform charge distribution (because the cooling system needs to remove heat uniformly). Therefore, the electron-charge concept does not have any burden of cost and weight for the hydrogen storage tank system. The energy consumption for the electron-charge enhancement method is quite low or omitted for electrostatic mode and ultra-capacitor mode in comparison of other hydrogen storage …

U.S. Trade Remedy Laws and Nonmarket Economies: A Legal Overview (open access)

U.S. Trade Remedy Laws and Nonmarket Economies: A Legal Overview

Two major U.S. trade remedies are antidumping (AD) law, which combats the sale of imported products at less than their fair market value, and countervailing duty (CVD) law, which aims to offset foreign government subsidization of imported goods. This report discusses these two law's impact on U.S. foreign relations.

Tools to support interpreting multiple regression in the face of multicollilnearity

This article argues that rather than using one technique to investigate regression results, researchers should consider multiple indices to understand the contributions that predictors make not only to a regression model, but to each other as well.

An Experimental and Theoretical Study of Ti-6Al-4V to Multi-mbar Pressures (open access)

An Experimental and Theoretical Study of Ti-6Al-4V to Multi-mbar Pressures

We report results from an experimental and theoretical study of the ternary alloy Ti-6Al-4V to 221 GPa. We observe a phase transition to the hexagonal {omega}-phase at approximately 30 GPa, and then a further transition to the cubic {beta}-phase starting at 94-99 GPa. We do not observe the orthorhombic {gamma} and {delta} phases reported previously in pure Ti. Computational studies show that this sequence is possible only if there is significant local atomic ordering during the compression process, yet insufficient atomic diffusion to reach the phase separated thermodynamic equilibrium state.

Framework Application for Core Edge Transport Simulation (FACETS) (open access)

Framework Application for Core Edge Transport Simulation (FACETS)

The goal of the FACETS project (Framework Application for Core-Edge Transport Simulations) was to provide a multiphysics, parallel framework application (FACETS) that will enable whole-device modeling for the U.S. fusion program, to provide the modeling infrastructure needed for ITER, the next step fusion confinement device. Through use of modern computational methods, including component technology and object oriented design, FACETS is able to switch from one model to another for a given aspect of the physics in a flexible manner. This enables use of simplified models for rapid turnaround or high-fidelity models that can take advantage of the largest supercomputer hardware. FACETS does so in a heterogeneous parallel context, where different parts of the application execute in parallel by utilizing task farming, domain decomposition, and/or pipelining as needed and applicable. ParaTools, Inc. was tasked with supporting the performance analysis and tuning of the FACETS components and framework in order to achieve the parallel scaling goals of the project. The TAU Performance System® was used for instrumentation, measurement, archiving, and profile / tracing analysis. ParaTools, Inc. also assisted in FACETS performance engineering efforts. Through the use of the TAU Performance System, ParaTools provided instrumentation, measurement, analysis and archival support for the FACETS …

Military Justice: Courts-Martial, An Overview

Recent high profile military-related cases involving U.S. armed forces in Afghanistan, including the deadly attack on Afghan civilians allegedly by a service member, the accidental burning of the Quran, and service members allegedly urinating on Afghan corpses, have resulted in increased public and congressional interest in military discipline and the military justice system. The Uniform Code of Military Justice (UCMJ) authorizes three types of courts-martial: (1) summary court-martial; (2) special court martial; and (3) general court-martial. Depending on the severity of the alleged offense, the accused's commanding officer enjoys great discretion with respect to the type of court-martial to convene. This report discusses the court martial procedure in further detail.

A Reconnection Switch to Trigger gamma-Ray Burst Jet Dissipation (open access)

A Reconnection Switch to Trigger gamma-Ray Burst Jet Dissipation

Prompt gamma-ray burst (GRB) emission requires some mechanism to dissipate an ultrarelativistic jet. Internal shocks or some form of electromagnetic dissipation are candidate mechanisms. Any mechanism needs to answer basic questions, such as what is the origin of variability, what radius does dissipation occur at, and how does efficient prompt emission occur. These mechanisms also need to be consistent with how ultrarelativistic jets form and stay baryon pure despite turbulence and electromagnetic reconnection near the compact object and despite stellar entrainment within the collapsar model. We use the latest magnetohydrodynamical models of ultrarelativistic jets to explore some of these questions in the context of electromagnetic dissipation due to the slow collisional and fast collisionless reconnection mechanisms, as often associated with Sweet-Parker and Petschek reconnection, respectively. For a highly magnetized ultrarelativistic jet and typical collapsar parameters, we find that significant electromagnetic dissipation may be avoided until it proceeds catastrophically near the jet photosphere at large radii (r {approx} 10{sup 13}-10{sup 14}cm), by which the jet obtains a high Lorentz factor ({gamma} {approx} 100-1000), has a luminosity of L{sub j} {approx} 10{sup 50}-10{sup 51} erg s{sup -1}, has observer variability timescales of order 1s (ranging from 0.001-10s), achieves {gamma}{theta}{sub j} {approx} 10-20 …

Russia's March 2012 Presidential Election: Outcome and Implications

Challenges to Russia's democratic development have long been of concern to Congress as it has considered the course of U.S.-Russia cooperation. Some in Congress have criticized the conduct of the election, but have endorsed continued engagement, while others have called for stepping back and reevaluating the Obama Administration's engagement policy which assists in solving mutual strategic concerns. Congress may consider the implications of another Putin presidency, lagging democratization, and human rights abuses in Russia as it debates possible future foreign assistance and trade legislation and other aspects of U.S.-Russia relations.

Oral History Interview with Raymond S. Pugh, March 14, 2012

The National Museum of the Pacific War presents an oral interview with Raymond S. Pugh. Pugh enlisted in the Navy when he was 17 in August, 1941. Pugh begins describing his career in the Navy with his activities on Tulagi. Pugh then shifts to discussing his role aboard the USS Hornet (CV-8) during the Doolittle Raid. He describes watching the pilots practicing taking off the carrier's deck in Chesapeake Bay before sailing through the Panama Canal, loading sixteen B-25s on the Hornet's deck at Alameda and rendezvousing with the USS Enterprise (CV-6) in the Pacific. Pugh recounts a story of encountering his brother at Pearl Harbor close to the end of the war.
