Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

open access: yesAnimal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market

Strong mine pressure appearing mechanism and control at deep buried working face with large mining height

open access: yesMeitan kexue jishu
During the mining of the adjacent working face, the strong mine pressure caused by the hard thick roof has obvious zoning characteristics due to the mining of the previous deeply buried large mining height working face. The mechanism of the strong mine pressure at the adjacent working face is the basis for realizing safe and efficient mining.

‘Sometimes, I would look at my books and cry because I felt like I was left behind’: Understanding the learning of Indigenous girls during the COVID‐19 pandemic in the districts of Chongwe and Solwezi in Zambia

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Grounded in principles of epistemic justice, this article examines the educational impacts of Zambia's COVID‐19 school closures on Indigenous girls in two districts and highlights community‐led pathways for resilience. National responses prioritised broadcast and digital delivery but presupposed access to electricity, digital devices and ...

Monitoring of Overburden Failure with a Large Fractured-Height Working Face in a Deep Jurassic Coal Seam Based on the Electric Method

open access: yesApplied Sciences
The development height of a water-flowing fractured zone is the key parameter to consider when carrying out mining under water pressure and coal mining with water conservation. In this paper, Jurassic coal seam 3-1 in the Menkeqing Coal Mine was taken as

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...
