First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

open access: yesThe Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Thermophilic anaerobic treatment and biogas generation from wastewater produced in an advanced biorefinery process

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.
