Fracture-controlled gas hydrate systems in the northern Gulf of Mexico [PDF]
, 2008 High-angle, open mode fractures control the presence of natural gas hydrate in water-saturated clays at the Keathley Canyon 151 site in the northern Gulf of Mexico, which was investigated for gas hydrates as part of the Chevron Joint Industry Project ...

Advanced Engineering Materials, EarlyView.Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Stress-Dependent Permeability of Naturally Micro-Fractured Shale
Geosciences, 2022 The permeability characteristics of natural fracture systems are crucial to the production potential of shale gas wells. To investigate the permeability behavior of a regional fault that is located within the Wufeng Formation, China, the gas permeability

Natural Course of Orbital Roof Fractures [PDF]
Craniomaxillofacial Trauma & Reconstruction, 2014 The natural course of several isolated and nonisolated orbital roof fractures is reported, by showing four cases in which a “wait and see” policy was followed. All four cases showed spontaneous repositioning and stabilizing of the fracture within less than a year.

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
