Investigation revealed the presence of generalized anhydrosis without evidence of an associated disease. Although chronic idiopathic anhydrosis is rare, this entity should be considered in cases of unexplained heat intolerance and heat stroke.

The influence of water vapour conditions on mass transport and barrier properties of chitosan based films and coatings were studied in relation to surface and structural properties. Water contact angles, material swelling, polymer degradation temperature, barrier properties (PO2, PCO2, WVP) and aroma diffusion coefficients were determined. The solvent nature and the presence of carvacrol influe...

The coastal ecosystems of French Guiana are very complex and changing due to the presence of huge quantities of mud originating from the Amazon. have been studied for more than a decade. Due to access difficulties through both land and sea, the use of remote sensing has always been essential, and the understanding of the complex landscapes was greatly improved when airborne and spaceborne imagi...
