Kobus has an excellent track record of success spanning over 20 years from the early days of his career to becoming Chief Process Engineer of research in a major multinational oil company, SASOL. Kobus has a B. Significant experience is referenced as the lead technical professional for major multidisciplinary investigations into industrial static and rotating equipment design, development, manufacturing, commissioning, and failure assessments.

Alchemy[ edit ] The term transmutation dates back to alchemy.

Thesis waste management

Alchemists pursued the philosopher's stonecapable of chrysopoeia — the transformation of base metals into gold. The impossibility of the metallic transmutation had been debated amongst alchemists, philosophers and scientists since the Middle Ages.

Pseudo-alchemical transmutation was outlawed [4] and publicly mocked beginning in the fourteenth century. Alchemists like Michael Maier and Heinrich Khunrath wrote tracts exposing fraudulent claims of gold making. By the s, Thesis waste management were no longer any respectable figures pursuing the physical transmutation of substances into gold.

The disintegration of atoms is a distinct process involving much greater energies than could be achieved by alchemists. Modern physics[ edit ] It was first consciously applied to modern physics by Frederick Soddy when he, along with Ernest Rutherforddiscovered that radioactive thorium was converting itself into radium in At the moment of realization, Soddy later recalled, he shouted out: They'll have our heads off as alchemists.

Blackett's experiments provided the first experimental evidence of an artificial nuclear transmutation reaction. Blackett correctly identified the underlying integration process and the identity of the residual Thesis waste management.

Ina fully artificial nuclear reaction and nuclear transmutation was achieved by Rutherford's colleagues John Cockcroft and Ernest Waltonwho used artificially accelerated protons against lithium-7 to split the nucleus into two alpha particles.

The feat was popularly known as "splitting the atom," although it was not the modern nuclear fission reaction discovered in by Otto HahnLise Meitner and their assistant Fritz Strassmann in heavy elements.

Save for the first five elements, which were produced in the Big Bang and other cosmic ray processes, stellar nucleosynthesis accounted for the abundance of all elements heavier than boron.

In their paper Synthesis of the Elements in Stars[9] William Alfred FowlerMargaret BurbidgeGeoffrey Burbidgeand Fred Hoyle explained how the abundances of essentially all but the lightest chemical elements could be explained by the process of nucleosynthesis in stars. It transpired that, under true nuclear transmutation, it is far easier to turn gold into lead than the reverse reaction, which was the one the alchemists had ardently pursued.

Nuclear experiments have successfully transmuted lead into gold, but the expense far exceeds any gain. More information on gold synthesis, see Synthesis of precious metals. Nucleosynthesis The Big Bang is thought to be the origin of the hydrogen including all deuterium and helium in the universe.

The Big Bang also produced small amounts of lithiumberyllium and perhaps boron. More lithium, beryllium and boron were produced later, in a natural nuclear reaction, cosmic ray spallation.

Stellar nucleosynthesis is responsible for all of the other elements occurring naturally in the universe as stable isotopes and primordial nuclidefrom carbon to uranium. These occurred after the Big Bang, during star formation.

Some lighter elements from carbon to iron were formed in stars and released into space by asymptotic giant branch AGB stars. These are a type of red giant that "puffs" off its outer atmosphere, containing some elements from carbon to nickel and iron.

All elements with atomic weight greater than 64 atomic mass units are produced in supernova stars by means of neutron capturewhich sub-divides into two processes: The Solar System is thought to have condensed approximately 4.

These grains contained the heavier elements formed by transmutation earlier in the history of the universe. All of these natural processes of transmutation in stars are continuing today, in our own galaxy and in others.

Stars fuse hydrogen and helium into heavier and heavier elements in order to produce energy.After the G-Zero: Overcoming fragmentation FALL Ian Bremmer GLOBAL RESEARCH PROFESSOR, NEW YORK UNIVERSITY PRESIDENT, EURASIA GROUP The views expressed in this paper are those of the author(s) only, and the presence of them, or of links to them, on.

Solid waste management is a challenge for the cities’ authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire.

olutions to the problem of solid waste in Panama. In , the Ministry of Health (MINSA) of Panama concluded that "as a result of surveys of mayors and communities nationwide," there is broad acceptance to landfill to give a solution to the problem of health environmental community [1].

More than million microwaves are affected by European Union (EU) legislation which is aimed at reducing the consumption of electricity in the standby mode (‘Standby Regulation’) and at more sustainable management of end-of-life electrical and electronic waste (‘WEEE Directive’).
