Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil. [PDF]

Anat Rec (Hoboken)
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Interdependencies between Indigenous peoples, local communities, and freshwater systems in a changing Amazon. [PDF]

Conserv Biol
Abstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...

Coating of Polypropylene Non‐Woven Fabric with Layered Double Hydroxides Bearing Antioxidant and Antibacterial Natural Compounds

Macromolecular Chemistry and Physics, Volume 224, Issue 23, December 2023., 2023
Polypropylene (PP) non‐woven fabric (NWF) can acquire antioxidant and antibacterial properties through the deposition onto the surface of hybrid powders based on layered double hydroxides (LDHs) and rosmarinic acid or eugenol extracted from sage and clove buds.

Fabrication and biocompatibility analysis of flexible organic light emitting diodes on poly(lactic acid) substrates: toward the development of greener bio‐electronic devices

Polymers for Advanced Technologies, Volume 33, Issue 5, Page 1523-1532, May 2022., 2022
Abstract The use of biodegradable and biocompatible materials for electronic applications is a research topic of great interest, offering the possibility to develop bio‐electronic devices and reduce e‐wastes. In this work, poly(lactic acid) (PLA) films were prepared to be employed as substrates in flexible optoelectronic devices and their functionality

Formation of Continental Microplates Through Rift Linkage: Numerical Modeling and Its Application to the Flemish Cap and Sao Paulo Plateau

Geochemistry, Geophysics, Geosystems, Volume 22, Issue 4, April 2021., 2021
Abstract Continental microplates are enigmatic plate boundary features, which can occur in extensional and compressional regimes. Here we focus on microplate formation and their temporal evolution in continental rift settings. To this aim, we employ the geodynamic finite element software ASPECT to conduct 3D lithospheric‐scale numerical models from ...

Effect of Airflow Field in the Tangential‐Longitudinal Flow Threshing and Cleaning System on Harvesting Performance

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
The threshing and cleaning device in the grain combine harvester is located in the same airtight space, and the air flow field in it should also be studied and tested as a whole system. In order to study the distribution of air flow field and the influence of working parameters on the air flow field in the internal space of threshing and cleaning ...
