Semigroup well-posedness and exponential decay of a viscoelastic bilateral contact model with Tresca’s law and infinite memory

In this article, we consider a dynamic contact for viscoelastic materials. The contact is bilateral, and the friction is modeled with Tresca’s friction law which provides a clear physical description of dry friction at the contact interface. The material is assumed to follow a no...

Contribution to the knowledge of the distribution of bats (Chiroptera) in Algeria

Algeria is the largest country in Africa and for the most part has not yet been surveyed for bat species. To contribute to the knowledge of the distribution of Algerian bat fauna, between 2011 and 2026 we surveyed 70 sites from 19 provinces across the country, mostly roost sites...
