Revisiting the Growth–Forest Sustainability Nexus in India: The Role of Human Capital, Energy, and Trade

Sustainable Development, EarlyView.
ABSTRACT Understanding whether the interaction between economic activity and forest ecosystems manifests as conflict or synergy is central to designing effective, sustainable development policies. Although the environmental Kuznets curve framework is frequently utilized to explain this relationship, its analytical scope remains limited, as it ...

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

Environmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Development of a Device Compatible with Universal Testing Machine to Perform Hole Expansion and Erichsen Cupping Tests

Machines, 2019
The material characterization regarding sheet metal formability is usually assessed by the forming limit curve (FLC). The FLC requires specialized and expensive equipment, several samples with different geometries, and can be a very time-consuming ...

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Emergence of Trichophyton indotineae in Switzerland (2014–2025): Clinical analysis and antifungal susceptibility

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Trichophyton indotineae is an emerging dermatophyte associated with chronic, recalcitrant dermatophytosis and terbinafine resistance due to squalene epoxidase (SQLE) mutations. We analyzed clinical characteristics, antifungal susceptibility profiles, SQLE mutations, and treatment outcomes of cases diagnosed in ...

An Experimental and Simulation Study on the Formability of Commercial Pure Titanium Foil

Micromachines
In order to understand the formability of as-received tempered commercial pure titanium grade 2 foils (CP Ti Gr2) with a thickness of 38 µm, a series of micro limited dome height (µ-LDH) tests were conducted in quasi-static speed (0.01 mm/s) at room ...
