Effect Of Superconsciousness External Energy On Atomic, Crystalline And Powder Characteristics Of Carbon Allotrope Powders, Mahendra Kumar Trivedi, Rama Mohan Tallapragada Nov 2009

Effect Of Superconsciousness External Energy On Atomic, Crystalline And Powder Characteristics Of Carbon Allotrope Powders, Mahendra Kumar Trivedi, Rama Mohan Tallapragada

Mahendra Kumar Trivedi

Scientists are searching for eluding link between spirituality and science. Some believe fundamental essences of universe to be energy and information. As per current understanding, energy and matter always coexisted and is considered one and the same. Energy is considered as ‘matter in perpetual motion’ and matter as ‘stationary energy’. Interconversion between matter and energy has been defined by Einstein’s famous energy–mass equation (E=mc2) which has been proven by nuclear physicists using complex nuclear reactions involving high energy particles. However, many spiritual masters have claimed to realise this energy–matter interconversion using their spiritual powers/energy but scientifically unknown and unverified. It …

Effect Of External Energy On Atomic, Crystalline And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi, Vikram V. Dabhade, Rama Mohan Tallapragada Sep 2009

Effect Of External Energy On Atomic, Crystalline And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi, Vikram V. Dabhade, Rama Mohan Tallapragada

Mahendra Kumar Trivedi

Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are com-pared with the as received powders (control). The average particle sizes, d50 and d99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy …

Gold. History, Metallurgy, Culture, Fathi Habashi Feb 2009

Gold. History, Metallurgy, Culture, Fathi Habashi

Fathi Habashi

Gold, the first metal used by man, has a special place among metals. It plays an important role in society and in world economics. It caused unprecedented mass migrations on three continents, and at least one war. It was responsible for creating many large cities, is highly prized, has been the inspiration of numerous myths, was the ultimate goal of alchemists, stored in the vaults of banks, widely on display in oriental bazaars, and is generously used in decorating churches and temples. The present volume is composed of two parts: a collection of selected papers published by the author on …

Cleaner Metallurgical Industry In Serbia: A Road To The Sustainable Development, Zeljko J. Kamberovic Dec 2008

Cleaner Metallurgical Industry In Serbia: A Road To The Sustainable Development, Zeljko J. Kamberovic

Zeljko J Kamberovic

Since the sustainable development has been a global and fundamental objecttive, a metallurgical industrial sector faces some of the most difficult sustainability challenges of any industrial sector. On the other hand, the metallurgical production in Serbia is a very important part of the economy. Due to present facilities and technologies, metallurgical companies face a great challenge to fulfill the requirements introduced by legislature referring to the cleaner production and sustainable development. The state of art in the production, facilities, pollution with some answers to imposed challenges is presented.
