Ontogeny of murine bony semicircular canal form

The Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

The Design and Performance Analysis of a 15 g/mol Helium–Xenon Mixture Centrifugal Compressor

Aerospace
One of the primary parts of a closed Brayton cycle that uses a helium–xenon mixture as the working medium is a centrifugal compressor. Nowadays, there has been minimal research on the theoretical underpinnings and design procedures of a helium–xenon ...

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

Bulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Performance of large virus removal filters during AAV processing: Influence of flux and process disruptions

Biotechnology Progress, EarlyView.
Abstract As adeno‐associated viral vectors (AAV) continue to advance through the clinical pipeline, effective downstream purification strategies must be developed to ensure bulk drug purity and safety. AAV are produced within mammalian cells, bringing forth risks associated with viral contamination.

Effect of the gap between the diffuser blade and impeller blade on the internal complex flow and aerodynamic performance of a centrifugal compressor [PDF]

Mechanical Sciences
In this paper, the impact of the ratio (Rd= R2/R1) between the diffuser inlet radius (R2) and the impeller outlet radius (R1) on internal complex flow and the aerodynamic performance of a centrifugal compressor is deeply studied through numerical ...
