Subterranean environments contribute to three‐quarters of classified ecosystem services
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Experimental Parameter Study of the Factors Influencing Dry Dispersion Using Laser Diffraction
Laser light diffraction reveals how geometric, material and operational factors govern dry dispersion efficiency and particle size distribution of submicron cathode material. The findings provide guidance for systematic optimization of powder handling and subsequent processing steps.

TRAF3 negatively regulates platelet activation and thrombosis
CD40 ligand (CD40L), a member of the tumor necrosis factor (TNF) superfamily, binds to CD40, leading to many effects depending on target cell type. Platelets express CD40L and are a major source of soluble CD40L.

Field trip guide to Oligocene Limestones and Caves in the Waitomo District [PDF]
The field guide runs from Hamilton to Waitomo to Te Anga and return in limestone-dominated country developed in transgressive sedimentary deposits of the Oligocene Te Kuiti Group – a world class example of a temperate shelf carbonate depositional system.

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

The classification and management of limestone pavements - an endangered habitat [PDF]
This thesis describes an in-depth study of limestone pavements across North West England and North Wales. The aim was to combine elements of geodiversity and biodiversity in order to create a holistic limestone pavement classification to inform future ...

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]
The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

Energy Balancing of Electrochemical Alternatives to the Solvay Process
To overcome the CaCl2 and CO2 emissions custom to the conventional Solvay process in soda ash production, electrochemically based alternatives were investigated. In particular, the mass‐ and energy balances for chlor‐alkali electrolysis and bipolar electrodialysis‐based processes are discussed comprehensively in the presented work.
