We have introduced a simple family of birational transformations in the complex projective space CPn that are generated by the product of the Hadamard...
We analyse the properties of a particular birational mapping of two variables (Cremona transformation) depending on two free parameters ([var epsilon]...
Olive oil production results in important quantities of wastewater containing large amounts of total solids and organic carbon as well as low oil conc...
A new activation technique using alumina was developed for the removal of fluoride from water. This technique is based on an electro-activation by mea...
The main purpose of this paper is to determine the mechanisms which govern the adsorption of the phenol onto electro-activated carbon granules. This n...
