Uncertainty Quantification of geochemical and mechanical compaction in layered sedimentary basins [PDF]

, 2017
In this work we propose an Uncertainty Quantification methodology for sedimentary basins evolution under mechanical and geochemical compaction processes, which we model as a coupled, time-dependent, non-linear, monodimensional (depth-only) system of PDEs

Calcitic coverings of the lower jaw of Jurassic ammonites exhibit Bouligand-like structures

Communications Earth & Environment
Well-preserved layered structures have been reported for Jurassic ammonites’ aptychi, but the role, function, and origin of the lamination has been unclear.

Geochemical Equilibrium and Processes in Seawater

Geosciences, 2018
The geochemical equilibrium in seawater must be observed taking into account the chemical and geological, as well as biological, processes. The concept of equilibrium takes into account the composition of the system and the kinetics of the reactions ...

Prediction of Acid Mine Drainage Treatment by Open Limestone-Alkaline Material Channel and Implications for the Large Scale Implementation of Passive Treatment

Journal of MMIJ, 2022
In decades, various studies on passive treatment methods of acid mine drainage (AMD) have been actively conducted in order to reduce the cost of AMD treatment.

Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes [PDF]

, 2017
The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Predicting potential pollutant release from waste rock at the abandoned Beck mine (Karelia, Russia) by equilibrium kinetic modeling [PDF]

Bulletin of the Geological Society of Finland
The Beck mine, located in the Republic of Karelia, Russia, is an abandoned mining site with significant potential for environmental contamination due to the presence of potential pollutants in its waste rocks.

“Hidden” Landscape of Prehistoric Burial Monuments: The Use of Remote Sensing in the Detection of Neolithic Long Barrows in Bohemia (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

An Idea to Explore: From How to Why: Using Evolutionary Biochemistry to Inspire Biochemistry Education

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Traditional biochemistry instruction often emphasizes mechanistic detail, that is, how molecules and pathways function, without equally addressing why they have their present forms. This fact‐centered approach can leave students overwhelmed and disconnected from the broader scientific narrative.

Geochemical modeling of gold precipitation conditions in the Bloco do Butiá Mine, Lavras do Sul/Brazil

Anais da Academia Brasileira de Ciências, 2005
A geochemical modeling of gold deposition was performed using the EQ3/EQ6 software package using conditions inferred from geological, petrographic, geochemical and fluid inclusion data from the Bloco do Butiá gold mine, Lavras do Sul, RS.
