A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, Volume 14, Issue 1, Page 47-60, January 2026.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Gold mineralization in the Neo-Tectonic Region of Honje Formation and Cipacar Formation

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2018
The gold ore mineralization region is a zone of mineralization which is inseparable from the role of geological structures, one of which is fracture. The Cibaliung and surrounding areas are epithermal gold mineralization zones, in this region there are ...

Microscale geochemical variations in metamorphic‐hydrothermal scheelite and insights into trace element sources (Otago Schist, New Zealand)

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 659-674, December 2025.
ABSTRACT Scheelite (CaWO4) trace elements are frequently used to fingerprint sources of mineralising fluids or styles of mineralisation. However, the chemistries of scheelite from hydrothermal‐metamorphic Otago Schist scheelite‐quartz veins have complicated parageneses.

Enhanced mitochondrial respiration in peripheral blood mononuclear cells (PBMCs) from young children with overweight/obesity and insulin resistance

European Journal of Clinical Investigation, Volume 55, Issue 12, December 2025.
We investigated measures of mitochondrial function in certain types of blood cells and metabolism in 65 children, 5–10 years old. Compared to children of normal weight (n = 20), children with overweight/obesity (n = 28) and especially those with insulin resistance (n = 17), differed in how their cells produced energy.

Impact of Graphene/Nanocellulose on Nanocomposite Membrane for Methylene Blue Dye Removal and Antifouling Performance

Journal of Applied Polymer Science, Volume 142, Issue 43, November 15, 2025.
Nanocomposite membrane for methylene blue dye removal. ABSTRACT The development of membrane technologies in improving water purification systems has been extensively studied by many researchers to ensure efficient production of clean water sources. However, fouling of PVDF membrane results in low permeation and dye removal efficiency, causing a major ...

Metabolic Consequences of Hybridization in European Water Frogs (Pelophylax esculentus complex)

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Our study links hybridization, ploidy, and cell size to metabolic performance under varying oxygen and temperature conditions in an amphibian larval model. By revealing physiological constraints tied to genotype and mitonuclear mismatch, it provides mechanistic insights into how hybrid and polyploid organisms may respond to environmental change ...

Metabarcoding Close to Home: Songbird Nests as eDNA Aggregators for Trophic Ecology and Biodiversity Studies

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We present a novel method for extracting eDNA from whole bird nests and a LNA blocking oligonucleotide designed to reduce metabarcoding reads from nest building sparrows. Metabarcoding of 22 nests from a montane sagebrush steppe ecosystem detected 126 species, primarily insects, including putative diet items, ectoparasites, and confirmed nest predators.
