Numerical study of fracture arrest on snow cover [PDF]
Fracture and Structural Integrity, 2010 Under the hypothesis of a perfectly brittle phenomenon, avalanche triggering can be investigated numerically by means of Linear Elastic Fracture Mechanics (LEFM).

Ice Spheres as Model Snow: Tumbling, Sintering, and Mechanical Tests
Frontiers in Earth Science, 2019 The snow microstructure is crucial for the mechanical behavior of snow, but is usually simplified in numerical models. In Discrete Element Models (DEM), often used in snow mechanics, the microstructure is typically represented by sphere assemblies.

Business Strategy and the Environment, EarlyView.ABSTRACT Global climate change has elevated the strategic importance of corporate climate risk disclosure, yet the role of industry peer effects in shaping such disclosure remains underexplored. Grounded in social learning theory, this study proposes an “observation–imitation–reinforcement” framework and empirically tests it using panel data on Chinese

Carbon Energy, EarlyView.Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

The mechanics of snow friction as revealed by micro-scale interface observations
Journal of Glaciology, 2018 The mechanics of snow friction are central to competitive skiing, safe winter driving and efficient polar sleds. For nearly 80 years, prevailing theory has postulated that self-lubrication accounts for low kinetic friction on snow: dry-contact sliding ...

Chemistry – A European Journal, EarlyView.Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Chemie Ingenieur Technik, EarlyView.Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

A Review of Russian Snow Avalanche Models—From Analytical Solutions to Novel 3D Models
Geosciences, 2020 The article is a review of mathematical models of snow avalanches that have been proposed since the middle of the 20th century and are still in use. The main attention is paid to the work of researchers from the Soviet Union and Russia, since many of ...
