Dynamic Property Analysis of Orthotropic Bridge Deck with Local Fatigue Crack
Advances in Civil Engineering, 2022 With the increase in traffic volume and overweight vehicles, fatigue problems are highlighted. Especially for the orthotropic steel deck, the premature cracks seriously affect the service performance, operation, and service quality of the bridge. In this

Enhanced silicate weathering is not limited by silicic acid saturation [PDF]
Proceedings of the National Academy of Sciences, 2011 Enhanced weathering of olivine as a means of sequestering carbon is investigated by Kohler et al. (1). Specifically, the study discusses the potential distribution of fine olivine powder, obtained from dunite mines, in the humid tropic regions of the Amazon and Congo River catchments. Olivine (forsterite) dissolution (Eq.

On the Anomalous Silicate Absorption Feature of the Prototypical Seyfert 2 Galaxy NGC 1068 [PDF]
MNRAS, 406, L6-L10 (2010), 2012 The first detection of the silicate absorption feature in AGNs was made at 9.7 micrometer for the prototypical Seyfert 2 galaxy NGC 1068 over 30 years ago, indicating the presence of a large column of silicate dust in the line-of-sight to the nucleus.

First Deployment and Validation of in Situ Silicate Electrochemical Sensor in Seawater
Frontiers in Marine Science, 2018 An electrochemical sensor is proposed to measure silicate concentration, in situ, in the ocean without any addition of liquid reagent. From the analytical principle to the laboratory prototype toward the first in situ, immersible sensor, the evolution of

A structure hierarchy for silicate minerals: sheet silicates [PDF]
Mineralogical Magazine, 2018 AbstractThe structure hierarchy hypothesis states thatstructures may be ordered hierarchically according to the polymerisation of coordination polyhedra of higher bond-valence. A hierarchical structural classification is developed for sheet-silicate minerals based on the connectedness of the two-dimensional polymerisations of (TO4) tetrahedra, where T =
