Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

‘Let's talk about the weather’: The activist curriculum and global climate change education

British Educational Research Journal, EarlyView.
Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...
