How Weather Affects over Time the Repeatability of Spectral Indices Used for Geological Remote Sensing

Remote Sensing, 2022
Geologic remote sensing studies often targets surface cover that is supposed to be invariant or only changing on a geological timescale. In terms of surface material characteristics, this holds for rocks and minerals, but only to a lesser degree for ...

Elucidating the crystal-chemistry of Jbel Rhassoul stevensite (Morocco) by advanced analytical techniques [PDF]

, 2008
The composition of Rhassoul clay is controversial regarding the nature of the puremineral clay fraction which is claimed to be stevensite rather than saponite.

Geological Controls on Geochemical Anomaly of the Carbonaceous Mudstones in Xian’an Coalfield, Guangxi Province, China

Energies, 2022
The anomalous enrichment of the rare earth elements and yttrium (REY), U, Mo, As, Se, and V in the coal-bearing intervals intercalated within the carbonate successions in South China has attracted much attention due to the highly promising recovery ...

Mineral consolidants

Proceedings of the International RILEM Conference Materials, Systems and Structures in Civil Engineering 2016 - Segment on Historical Masonry, 2016
Inorganic consolidants, such as ethyl silicate, nanolime and ammonium oxalate, have proven to be effective for certain materials, but each has its drawbacks. This has recently led to the investigation of hydroxyapatite (HAP) as a novel inorganic consolidant, which demonstrated excellent performance on carbonate stones.

Reservoir theory for studying the geochemical evolution of soils [PDF]

, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

FEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Níveis nutricionais de cobre para frangos de corte machos e fêmeas na fase inicial Copper nutritional levels for male and female broilers in the initial phases

Revista Brasileira de Zootecnia, 2005
Com o objetivo de determinar a exigência de cobre (Cu) para frangos de corte na fase inicial (8 - 21 dias), foram utilizadas 384 aves, metade machos e metade fêmeas. Foi elaborada uma dieta basal atendendo às exigências nutricionais das aves, com exceção

Nitric acid scavenging by mineral and biomass burning aerosols [PDF]

, 1998
The abundance of gas phase nitric acid in the upper troposphere is overestimated by global chemistry-transport models, especially during the spring and summer seasons.

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

FEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...
