Prediction of magnetite segregation in dense medium cyclone using computational fluid dynamics technique

, 2007
Multi-phase simulations of turbulent driven flow in a dense medium cyclone with magnetite medium have been conducted in Fluent, using the Algebraic Slip Mixture model to model the dispersed phases and the air-core, and both the Large Eddy Simulation ...

Unbiased fully nonlinear data assimilation. Part 2: The stochastic particle flow smoother

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Building on the stochastic particle flow filter (SPFF) introduced in Part 1, we introduce a new smoother—the stochastic particle flow smoother (SPFS)—for high‐dimensional, nonlinear data assimilation. We examine two backward‐propagation strategies for the smoother, including an exact adjoint model, which allows particles to capture multimodal ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Resilience and Sustainability Through Interlinkages of Gender, Disaster, and Climate Change: A Systematic Literature Review

Sustainable Development, EarlyView.
ABSTRACT This systematic literature review examines gendered vulnerabilities, adaptive capacities, and policy translation in climate‐change induced disaster research using an intersectional lens in the Web of Science Database. Peer‐reviewed journal articles published in English between 2014 and 2024 focusing on gender, climate change, and disaster were

Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

Small, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Coupling Plasma‐Synthesized N‐Doped Graphene With Ice Templated Porous Electrode for Enhanced Aluminum Battery Performance

Small, EarlyView.
A plasma‐assisted strategy is developed to synthesize nitrogen‐doped graphene and construct a porous electrode through directional freezing and freeze‐drying. The resulting porous architecture improves electrolyte accessibility and AlCl4– transport, enabling enhanced surface‐controlled charge storage, rate capability, and cycling stability in aluminum ...

Experimental Investigation of Electrical Parameter Effects in Wire Arc Atomization of 316L Stainless Steel Powders for Additive Manufacturing

steel research international, EarlyView.
This article presents wire arc atomization of 316L for the production of metallic powders used in additive manufacturing, with a systematic analysis of the influence of arc parameters on particle size. Through the application of dry sieving, scanning electron microscopy, and shape analysis, it is demonstrated that this technique is well‐suited for ...

Herbivore versus detritivore effect on decomposition through leaf conversion into faeces

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In terrestrial ecosystems, plant residues can reach the soil as senesced leaf litter or green leaves, and both types can be transformed by invertebrates into detritivore or herbivore faeces.

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Palestine, Public Sentiment and the Limits of Omani Foreign Policy Discourse

Global Policy, EarlyView.
ABSTRACT This article examines how expressions of solidarity with Palestine in Oman reveal transformations in state–society relations during the Gaza war of 2023–2025, a period of leadership transition and regional rupture. Drawing on elite statements, opinion columns and semi‐structured interviews, it combines framing analysis with thematic analysis ...
