Impact of Cattaneo–Christov Heat and Mass Flux on MHD Hybrid Nanofluid Flow Over an Extending Surface With Convective and Mass Flux Effects

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the flow of a magnetized hybrid nanofluid over a permeable stretching surface. The mass and thermal transport within the system is regulated using the Cattaneo–Christov flux theory. The fluid is additionally subjected to thermophoresis, chemical reaction, Brownian motion, and activation energy effects.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

CONTRIBUTION TO THE GENESIS OF THERMAL WATER OF THE NORTH-EAST PERIMETER OF THE ZENICA-SARAJEVO BASIN, BOSNIA AND HERZEGOVINA

open access: yesRudarsko-geološko-naftni Zbornik, 2017
The phenomena of thermal waters in the northeastern periphery of the Zenica-Sarajevo basin is caused by the geological structure, structural-tectonic and hydrogeological characteristics of the terrain.

Diversity as a general basis of tourism – system approach [PDF]

open access: yes, 2015
The general basis for tourism consists in the diversity of natural and man-made environment. The diversity can be considered as a natural characteristic of natural and anthropogenic systems produced by them as a condition of its continuance and ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.
