Deghosting of Ocean Bottom Cable Data:Two approaches [PDF]

open access: yesProceedings of the 5th Conference & Exposition on Petroleum Geophysics,organized by SPG,India,2004, 2005
Two filter based approaches for deghosting of Ocean Bottom Cable data are presented. One of them is phase shifting of geophone followed by least square matching of cross ghosted geophone and hydrophone data.In the second approach,phase shifting of geophone is followed by direct matching of geophone's amplitude spectrum with that of the hydrophone ...

Petroleum in Canada [PDF]

open access: yesGeological Society of America Bulletin, 1917
Production Compared with the United States, Canada is but a small producer of petroleum, the output of the two countries for the year 1915 being about 281,104,104 and 215,464 barrels respectively. In other words, the production of Canada was less than one-tenth of one per cent of that of the United States.

Sustained Release of Proteins Using Region‐Specific Tunable Degradability in Hydrogels through 3D Photopatterning and Complimentary Labile Bond Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...
