Decision making is defined as the selection of a course of action among alternatives, ie that there is a plan of compromise or reputation management resources. Sometimes engineers consider decision making as their main job ...

Textile industries not only consume large volumes of water; they dispose of a large amount of pollutants in their effluents. It is estimated that this industry generates 120 m3 of wastewater for every ton of dyed fiber, ...

In this work we present the experimental results of studying the phenomenon of thermally stimulated luminescence (TL) of trifluoride potassium magnesium doped with terbium (KMgF3:Tb) exposed to several doses of ionizing ...

The lack of treatment of industrial effluents and those that contain uncommon and harmful substances at normal conditions in the environment has had as a consequence the gradual degradation of the organic and inorganic ...

This work reports the thin films of hybrid perovskite CH3NH3PbI3 doped with chlorine and tin. The precursor solution was made from lead iodide, methylammonium iodide and tin chloride, on a heating grill at a temperature ...

The residual water originating from diverse chemical processes, they contain composed that transfer them color. Even and when in our federal regulatory nature, this parameter is not found established norms for, cases exist ...

(Potassium Magnesium Fluoride doped with terbium) via microwave synthesis, as well as its thermoluminescent response is described. TL response is especially important because it indicates if the material is suitable to be ...

Water on Earth is one of the most abundant natural resources, but only about 1% of that resource is available for human consumption. It is estimated that more than 1.1 billion people lack adequate drinking water supply, ...

In recent years the human being search alternatives to accelerate the return to equilibrium conditions in natural ecosystems, one of these alternatives accelerating degradation of contaminants by heterogeneous photocatalysis. ...

A great deal of water is used in cellulose and paper industry; it is mostly devoted to clean and whiten cellulose. This waste water presents a 2400 unit of platinum-cobalt colored appearance, a 7.1 PH level, a conductivity ...
