Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

open access: yesPolymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Variability in Avian Eggshell Colour: A Comparative Study of Museum Eggshells

open access: yesPLoS ONE, 2010
The exceptional diversity of coloration found in avian eggshells has long fascinated biologists and inspired a broad range of adaptive hypotheses to explain its evolution. Three main impediments to understanding the variability of eggshell appearance are: (1) the reliable quantification of the variation in eggshell colours; (2) its perception by birds ...

Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

open access: yesJournal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

UAVs unveil the role of small scale vegetation structure on wader nest survival

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Innovation in the Spaces In‐Between: Creating the Nexus Between Human and Non‐Human Actors in Systemic Innovations

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT By combining theories of system thinking with a post‐humanist approach, we established a nexus between human and non‐human systems in the examination of systemic innovation. By doing so, we shed light on the interdependencies that exist between human and non‐human systems and contribute theoretically as well as methodologically to theories on ...

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.
