Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi
Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi
Fathi Habashi
The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.
Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi
Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi
Fathi Habashi
While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.
Phosphate Industry And The Radon Problem, Fathi Habashi
Phosphate Industry And The Radon Problem, Fathi Habashi
Fathi Habashi
The problem of radon generated during the treatment of phosphate rock by sulfuric acid to produce fertilizers can be solved by using nitric acid. In this case radium, which is the source of radon, goes into solution and can be precipitated by a controlled method and safely disposed of. A variety of options are discussed. Text in Farsi with English translation.

International Law, State Sovereignty And Transboundary Waters, Aguinaldo Alemar
International Law, State Sovereignty And Transboundary Waters, Aguinaldo Alemar
Aguinaldo Alemar
The current status of transboundary water resources is to claim a more proactive posture by the sovereign states, mainly those having large reserves of fresh water shared. This new posture involves actions between the states as a key condition to the success of any enterprise that aims to protect the environment. It intends to prove that other actors - national and international - are already mobilizing themselves to consider water as a "common heritage of mankind" and, as such, water must be considered above the classical concepts of sovereignty and territory, excelling by the humanitarian interest that it arouses. At …
The Biology Of Reality Testing - Implications For Cognitive Education, Neil Greenberg
The Biology Of Reality Testing - Implications For Cognitive Education, Neil Greenberg
Neil Greenberg
• This report explores the proposition that teaching effectiveness can be enhanced by accommodating the key differences between two complementary and deeply engrained modes of reality testing, each predominantly centered in different hemispheres of the brain. • (1) Correspondence involves “reality-testing” of a percept, the cerebral representation of an experience in the world. • (2) Coherence involves “textualizing”, that is, reality-testing of a percept by how easily it relates to previous and ongoing parallel and collateral experiences. • Confidence in the validity of any percept throughout development is related to the interplay of these key processes. • As organisms develop, …
Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi
Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi
Fathi Habashi
Water a component of the Four Elements considered by the ancient philosophers as essential for survival, played, and is still playing an essential role in society. Great civilizations in ancient times developed along great rivers. The ancient peoples knew how to manage water supplies by digging canals, controlling floods, and using water for irrigation. They designed equipment that used water to measure the time, to determine the density of solids, to fight fires, and to create vacuum. Modern engineers exploited water flow to design and construct huge hydroelectric power stations. Waterways and navigation systems were also an essential element for …
