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.

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.
