Americium was first produced in 1944 by the group of Glenn T. Seaborg at the University of California, Berkeley.

One such proposal calls for a gas cooled fast reactor that is fueled primarily by Plutonium and Americium.

During his Manhattan Project research in 1943 Glenn T. Seaborg experienced unexpected difficulty isolating Americium ( 95 ) and Curium ( 96 ).

Americium ( ) is a transuranic radioactive chemical element that has the symbol Am and atomic number 95.

Americium is a relatively soft radioactive metal with silvery appearance.

Americium was detected in the fallout from the Ivy Mike nuclear test.

An Americium container from a smoke detector.

The neutronic properties of Americium make it difficult to use in any critical reactor because it tends to make the moderator temperature coefficient more positive, decreasing stability.

The inherent safety of an ADS, however, would allow Americium to be safely burned.

Americium ( Am ) is an artificial element, and thus a standard atomic mass cannot be given.

The infant is discovered by a fisherman who brings him home to rear him.

That such deficiencies existed within Ptolemy's theory was not discovered de novo by Copernicus.

In all the talk of feudal rights, the knights and bishops must never forget the woolworkers, nor was it easy to do so, for all along the road to Italy they passed the Florentine pack trains going home with their loads of raw wool from England and rough Flemish cloth, the former to be spun and woven by the Arte Della Lana and the latter to be refined and dyed by the Arte Della Calimala with the pigment recently discovered in Asia Minor by one of their members, Bernardo Rucellai, the secret of which they jealously kept for themselves.

He was outraged by the book and announced that he had discovered fifty technical errors in its account of church practices.

And the second requirement for convincing people without their knowledge is artistic talent to prepare the words and pictures which persuade by using the principles which the scientists have discovered.

From this point of view the `` militant mobs '' of the past, stirred into action by one ideology or another, were all composed of `` intellectuals '' -- and this is not the level on which the essence of mankind can be discovered.

We had merely been discovered by the pool sharks.

In this manner, the factors measured by the intelligence test were controlled, allowing discovered differences in achievement to be interpreted as resulting from other variables.

or allowing a deduction for payment of certain obligations of a transferor assumed in the reorganization ( section 381(c)(16) ), but not a deduction for theft losses sustained by a transferor prior to a reorganization but discovered after it ; ;

Little by little, during the week, Chris and I discovered the crazy unbelievable way Nadine and Wally had lived.

They lay months away from the nearest Earth star by jump drive, and no one knew what they were good for, although it was felt that they would probably be good for something if it could only be discovered -- much like the continent of Antarctica in ancient history.

Recently however, funding of projects such as the Lincoln Near-Earth Asteroid Research and Near Earth Asteroid Tracking projects has meant that most comets are now discovered by automated systems, long before it is possible for amateurs to see them.

Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerine ( discovered in 1847 by Ascanio Sobrero, one of his fellow students under Théophile-Jules Pelouze at the University of Turin ).

In 1789, French nobleman and scientific researcher Antoine Lavoisier discovered the law of conservation of mass and defined an element as a basic substance that could not be further broken down by the methods of chemistry.

An additional line of reasoning in support of particle theory ( and by extension atomic theory ) began in 1827 when botanist Robert Brown used a microscope to look at dust grains floating in water and discovered that they moved about erratically — a phenomenon that became known as " Brownian motion ".

In 1909, Hans Geiger and Ernest Marsden, under the direction of physicist Ernest Rutherford, bombarded a sheet of gold foil with alpha rays — by then known to be positively charged helium atoms — and discovered that a small percentage of these particles were deflected through much larger angles than was predicted using Thomson's proposal.

It has recently been discovered that the location and extent of a neuron's AIS can be altered by the neuron's level of activity and that these changes are thought to influence the excitability of the neuron.

In 1992 – 1993 a research team headed by Tim White discovered the first A. ramidus fossils — seventeen fragments including skull, mandible, teeth and arm bones — from the Afar Depression in the Middle Awash river valley of Ethiopia.

Between 1999 and 2003, a multidisciplinary team led by Sileshi Semaw discovered bones and teeth of nine A. ramidus individuals at As Duma in the Gona Western Margin of Ethiopia's Afar Region.

* 1932 – The positron ( antiparticle of the electron ) is discovered by Carl D. Anderson.

One of the earliest group automorphisms ( automorphism of a group, not simply a group of automorphisms of points ) was given by the Irish mathematician William Rowan Hamilton in 1856, in his Icosian Calculus, where he discovered an order two automorphism, writing:

George T. Simon discovered a saxophonist named Wilbur Schwartz for Glenn Miller.

After oil was discovered at Glenn Pool in adjacent Tulsa County in 1905, other strikes occurred in Creek County.

In 1941 an oilfield was discovered nearby, leading the way for the oil businessman Glenn H. McCarthy to establish a gas plant just east of the town.

While there, he " discovered distortion " and worked with composer Glenn Branca.

Adams next starred in the sixth Godzilla film, Invasion of Astro-Monster ( known in the U. S. as Monster Zero ), in which he played Astronaut Glenn, journeying to the newly discovered Planet X.

In the late 1960s, a two-man spacecraft, crewed by a Japanese and American ( Fuji and Glenn ), approaches Jupiter's orbit to explore the newly discovered Planet X.

Marion Hutton was discovered by Glenn Miller and was invited to join the Glenn Miller Orchestra in 1938.

According to Glenn Hall, Conn Smythe " ostracized " his captain when he discovered Kennedy had not told him about Lindsay's endeavors.

Seaborg is the son of Helen L. Seaborg and Nobel Laureate Glenn T. Seaborg ( who discovered plutonium among many other accomplishments ).
