Calcium phosphates are essential components in the development of bioactive materials because of their perfect biocompatibility, their ability to bio-degradation and their biological reactivity. In fact, their chemical compositions are similar to the hard tissue of bone and teeth. We are interested in the synthesis of a calcium phosphate-carbonated apatite.(More)
The use of Procambarus clarkii in human gastronomy is a cultural issue in the world. Since it is used in human nutrition, can potentially bioaccumulate heavy metals, it is important to quantify the toxicological risk posed by its consumption. The human consumption of crayfish could be restricted based on current criteria for Cu, Pb, and Cd. Different(More)
This study examines the geographic variability in otolith shape of round sardinella Sardinella aurita as a tool for stock discrimination. Fish were analysed from six sampling locations from Senegal to the Mediterranean coast of Morocco. A combination of otolith shape indices and elliptic Fourier descriptors was investigated by multivariate statistical(More)
