Heavy Metal Accumulation (Cd, As, Zn, Cu, Cr) in Hair and Bones of Small Mammal Prey of the Sentinel Species Common Genet () in an Anthropogenic Environment of Edough Mountain Forest, Northeastern Algeria.

Heavy metal pollution has complex impacts on terrestrial ecosystems, affecting biodiversity, trophic relationships, species health, and the quality of natural resources. This study aims to validate a non-invasive method for detecting heavy metals (Cd, As, Zn, Cu, Cr) in micromammalian prey, which constitute the primary diet of the common genet (), a mesocarnivore sensitive to habitat degradation. By focusing on prey remains (hair and bones) rather than entire fecal samples, this approach leverages the genet's selective feeding habits to assess the bioaccumulation of contaminants in its preferred prey.

Density functional theory investigation of the phase transition, elastic and thermal characteristics for AuMTe(M = Ga, In) chalcopyrite compounds.

We explored the pressure-induced structural phase transitions and elastic properties of AuMTe (M = Ga, In) using the full-potential linearized augmented plane wave method within the framework of density functional theory, applying both generalized gradient and local density approximations. Thermodynamic properties were further assessed through the quasi-harmonic model. We determined the transition pressures for the phase shift from the chalcopyrite structure to the NaCl rock-salt phase in both AuGaTe and AuInTe.

Frailty models are important for survival data because they allow for the possibility of unobserved heterogeneity problem. The problem of heterogeneity can be existed due to a variety of factors, such as genetic predisposition, environmental factors, or lifestyle choices. Frailty models can help to identify these factors and to better understand their impact on survival.
