Abstract: The characterization of reservoir pore structure is crucial for the exploration and development of oil, gas, and water resources, as well as for carbon dioxide sequestration. Nuclear ...

Abstract: In the dual-inertia servo system, the servo resonance in which the characteristics are closely related to the mechanical parameters is usually suppressed by adding a notch filter. As a ...

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system. Hydroxyl compounds ...

When the cameras scan the directors’ box at Tottenham Hotspur Stadium, a familiar figure will be missing. Daniel Levy, once the ever-present executive chairman, has been moved aside after more than ...

Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model. Still, the physical reason ...

The Lewis Structure explorer was designed to give students real-time feedback while drawing Lewis Structures with a digital interactive tool, Figure 1. The interactive provides visual feedback using ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

Carbon dioxide is uniquely suited to cause global warming because of a coincidental quirk of quantum mechanics. Global warming is largely caused by carbon dioxide and other gases absorbing infrared ...
