Combined U-Pb SHRIMP and Hf isotope study of the Late Paleozoic Yaminué Complex, Rio Negro Province, Argentina : implications for the origin and evolution of the Patagonia composite terrane

, 2013
We have carried out zircon U-Pb SHRIMP dating and Hf isotope determinations on a biotite paraschist and on a tonalitic orthogneiss of the Yaminue Complex, and re-evaluate this complex in the broader context of the tectonic evolution of the Patagonia ...

Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

Animal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Triassic mineralization with Cretaceous overprint in the Dahu Au-Mo deposit, Xiaoqinling gold province: Constraints from SHRIMP monazite U-Th-Pb geochronology

, 2011
The Xiaoqinling terrane in central China is the second largest gold producing area in China. Previous application of age constraints has yielded ages for the gold mineralization ranging from Paleoproterozoic.

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

Animal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

SIMS study of fine-scale distribution of U, Th and Pb in meteorites

Journal of Analytical Science and Technology
We report developing a procedure for measuring concentrations of U, Th and Pb (including all natural Pb isotopes) to establish the distribution of these elements in meteorite minerals and correctly interpret Pb-isotopic ages of meteorites.

SHRIMP zircon U-Pb dating for two episodes of migmatization in the Dabie orogen

Chinese Science Bulletin, 2007
Zircon CL imaging and SHRIMP U-Pb dating were carried out for migmatite in the Dabie orogen. Zircons from the Manshuihe migmatite show clear core-rim structures. The cores display sector or weak zoning and low Th/U ratios of 0.01 to 0.17, indicating their precipitation from metamorphic fluid. They yield a weighted mean age of 137±5 Ma. By contrast, the

Creating space(s) for learning in prison: Developing an andragogical framework

British Educational Research Journal, EarlyView.
Abstract Learning in prison is too often excluded from wider discussions of educational experiences, processes and impact. This paper proposes, for the first time, an iterative andragogical framework to conceptualise learning spaces within prison contexts.
