Bite force estimates and morphological correlations of jaw muscles in parrots

The Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Precession and Nutation of the Earth

, 2009
International audiencePrecession and nutation of the Earth originate in the tidal forces exerted by the Moon, the Sun, and the planets on the equatorial bulge of the Earth. Discovered respectively in the 2nd century B.C.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Biochemical Studies and Production Optimization of β‐Glucosidase From Microcystis aeruginosa CACIAM 03 Using Organic Waste

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Global warming and industrial pollutants pose significant threats to environmental sustainability. In response, enzymes have emerged as promising tools for mitigating pollution. Enzymatic hydrolysis is considered environmentally sustainable due to its biological nature.

Optimization design of radial meshing nutation magnetic gear system based on D-APSO algorithm

Advances in Mechanical Engineering
To combine the high transmission ratio of nutation drives with the non-contact power transfer of permanent-magnet gears, this paper proposes a novel radial meshing nutation magnetic drive system (RMNMD) and investigates its magnetic coupling mechanism ...

Biogas purification and enrichment: sustainability metrics analysis of dry anaerobic digester with cashew apple bagasse substrate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study hypothesizes that cashew apple bagasse‐based anaerobic digestion, combined with biochar purification, enhances biogas quality and sustainability. This study aims to investigate the performance and sustainability of a biochar‐based biogas purification technology using cashew apple bagasse as a substrate, with a focus on environmental

Quadrupole Nutation NMR in Solids

Zeitschrift für Naturforschung A, 1992
Abstract The nutation frequency of a quadrupolar spin I depends on the quadrupole interaction. From nutation spectra, therefore, one obtains information about the direct surrounding of the atom. The theory of the straightforward and of more complicated nutation NMR experiments is outlined.

Study on the dynamic load sharing characteristics of nutation face gear transmission

Discover Applied Sciences
The nutation face gear transmission is a type of power splitting, and the effects of system parameters such as stiffness and transmission error on load distribution are not yet well understood. The Load Tooth Contact Analysis (LTCA) technique was used to

A repertoire of middle leading practices: A large‐scale investigation of middle leadership in schools

British Educational Research Journal, EarlyView.
Abstract This article presents findings from an Australian study investigating the practices of middle leaders responsible for facilitating school development. Despite middle leaders being increasingly recognised as essential in the development of teaching and learning in schools, middle leadership remains under‐researched and comparatively overlooked ...

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

Bulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...
