Thirty-six microalgae belonging to five taxonomic groups (Cyanobacteria, Chlorophyceae, Diatomophyceae, Euglenophyceae, and Eustigmatophyceae) were identified from six freshwater ecosystems in Morocco, two treatment stations in Etueffont landfill in France and three hot spring waters in Tunisia. Investigations on species growth kinetics and growth rates showed that the cyanobacterium Leptolyngbya gelatinosa exhibited both the highest biomass and growth rate with 4 g L and 0.282 day, respectively.

We developed anframework that estimates the radiation doses received by lymphocytes during volumetric modulated arc therapy brain irradiation.

- The study investigates the out-of-field dose delivered during external photon beam radiation therapy, as it may lead to a higher risk of second cancers and affect immune system efficiency in radio-immunotherapy treatments.
- Traditional methods for estimating out-of-field doses are complex and not suitable for clinical use, prompting the exploration of deep learning techniques for more effective dose map prediction.
- A 3D U-Net model, trained on data from 3,151 pediatric patients, demonstrated promising results in estimating out-of-field doses, achieving low error rates in both training and validation, indicating potential for clinical application.
This work constitutes a new trial to enhance the properties of palladium supported on alumina modified with zirconium used as catalysts for methane combustion. The effect of the support drying mode is studied. For this aim, AlO-ZrO binary oxides with zirconium loading of 2 and 5% in weight were prepared using sol-gel process then dried under ordinary or supercritical conditions.

Our study aimed to describe the profile of human exposures to animals over fifteen years and to assess the post-exposure prophylaxis (PEP) practices in the governorate of Kasserine (Tunisia) on pre- and post-revolution (2011).
Methods: We carried out a descriptive study using surveillance data from a region in Central-West Tunisia.
