Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Enablers and Constraints of Environmental Sustainability Integration: A Structuration Perspective on Professional Sports Organizations

Business Strategy and the Environment, EarlyView.
ABSTRACT Integrating environmental sustainability (ES) into organizational strategies and operations remains a persistent challenge, particularly in fields where environmental concerns are not yet embedded within dominant institutional norms and standards of behavior. In such contexts, ES risks being overshadowed by economic and operational priorities,

Measurement of Strontium-90 in the Persian Gulf Fish by Extraction Chromatography with Sr-resin and Liquid Scintillation Counter

Iranian South Medical Journal, 2020
Background: Despite its beneficial effects on human life, the nuclear industry has its own risks. Strontium 90 (90Sr) is one of the most dangerous radionuclides produced by the uranium 235 fission, and replaces the bone calcium in the human body, which ...

Covalent Peptide‐Graphene Conjugates for Enhanced Cell Spreading, Osteogenic Differentiation, and Angiogenesis in Bone Defects

ChemBioChem, EarlyView.
The three peptides RGD, DGEA, and KKGHK are covalently attached to the 2D nanomaterial graphene oxide (GO) to create new biomaterials for the treatment of severe bone injuries. These GO modifications improve cell spreading, stem cell differentiation into bone cell types, and formation of blood vessel‐like structures.
