Hydrogen eliminator [PDF]

open access: yes, 1972
Vented hydrogen is converted into water by mixing hydrogen with sufficient air to ensure that a flame cannot be maintained and then passing it through a reactor containing palladium catalyst; reaction takes place at relatively low temperature. Device may

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Radiative interactions in chemically reacting supersonic internal flows [PDF]

open access: yes
The two-dimensional, elliptic Navier-Stokes equations are used to investigate supersonic flows with finite-rate chemistry and radiation for hydrogen-air systems.

‘Escaping Isn't for Everyone’: Kurdish Smugglers’ Navigational Tactics at Checkpoints in Iran

open access: yesDevelopment and Change, EarlyView.
ABSTRACT This article examines how Kurdish smugglers navigate state and insurgent checkpoints in the borderlands of western Iran. Drawing on ethnographic research, it analyses two key navigational tactics: persin, a form of negotiated passage involving transaction, recognition and the contingent toleration of authority; and jimi, rendered here as ...

Performance criteria guideline for three explosion protection methods of electrical equipment rated up to 15,000 volts AC [PDF]

open access: yes
The Bureau of Mines, U.S. Department of the Interior, is reviewing explosion protection methods for use in gassy coal mines. This performance criteria guideline is an evaluation of three explosion protection methods of machines electrically powered with ...

Enhanced Fire Retardancy of Vinyl Ester Resins by Combination of Additives [PDF]

open access: yes, 2007
In pursuit of fire-retardant materials, vinyl ester resins were combined with commercially available fire retardants at lower loadings than that at which they are usually effective when used alone.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

Chemical kinetic analysis of hydrogen-air ignition and reaction times [PDF]

open access: yes
An anaytical study of hydrogen air kinetics was performed. Calculations were made over a range of pressure from 0.2 to 4.0 atm, temperatures from 850 to 2000 K, and mixture equivalence ratios from 0.2 to 2.0.
