Void Dynamics [PDF]

Proceedings of the International Astronomical Union, 2014
Cosmic voids are becoming key players in testing the physics of our Universe. Here we concentrate on the abundances and the dynamics of voids as these are among the best candidates to provide information on cosmological parameters.

Spatial Behavior of Solutions in Linear Thermoelasticity with Voids and Three Delay Times

Mathematics, 2023
This brief contribution aims to complement a study of well-posedness started by the same authors in 2020, showing—for that same mathematical model—the existence of a domain of influence of external data.

An overview of the urbanism style during the Italian era in Benghazi downtown, Libya

Journal of Architecture and Urbanism, 2022
Axiomatically, urban fabric is the result of civilizations and ideas overlapping rather than being bound to a single civilization or culture. Benghazi, like many other Arab cities in developing countries, retains relics of its past in the old city core.

The Effect of Rhenium Content on Microstructural Changes and Irradiated Hardening in W-Re Alloy under High-Dose Ion Irradiation

Nanomaterials, 2023
An amount of 100 dpa Si2+ irradiation was used to study the effect of transmutation rhenium content on irradiated microscopic defects and hardening in W-xRe (x = 0, 1, 3, 5 and 10 wt.%) alloys at 550 °C.
