Innovative methods of extracting the loose gold from technogenic deposits in the Irkutsk region
MATEC Web of Conferences, 2018 In Russia and abroad, the scope of the use of gold has significantly expanded, which undoubtedly affected the level of production. However, despite the fairly high rates of gold mining, the economic situation that has developed in recent years makes the ...

PLACERS OF MAJOR VALLEYS IN THE LENA GOLD-PLACERS REGION
Proceedings of higher educational establishments. Geology and Exploration, 2017 The morphology and inner structure of the placers in the maj or valleys of the Lena gold-bearing area are considered. The morphology of placers in the plan and the distribution of gold within the contours of the valleys are determined by the morphodynamic type of the channels and their evolution in different parts of the valley.

Arthritis Care &Research, EarlyView.Objective Youth who experience a sport‐related knee injury have elevated odds of becoming overweight or developing obesity in 3 to 10 years, compounding their risk for posttraumatic osteoarthritis (PTOA). To inform prevention strategies, this study compared patterns of adiposity change between youth with a sport‐related knee injury and uninjured youth ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Advanced Engineering Materials, EarlyView.Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings
