Renewed negotiations begun twelve years later finally led to a treaty in 1186, but the earlier episodes seem to have created in Enrico Dandolo a deep and abiding hatred for the Byzantines.

<!~-- In the 2000s and on, Romero has worked on Durham Red, and other projects for the magazines 2000 AD and Judge Dredd Megazine, as Enric Romero, and in 2011 he drew for the Italian market some short stories of Djustine, the horror-western character created by Enrico Teodorani .-->

Plutonium is also fissile and can be used to create a fission reaction, and after Enrico Fermi achieved the world's first sustained and controlled nuclear chain reaction in the creation of the first " atomic pile "— a primitive nuclear reactor — in a basement at the University of Chicago, massive reactors were secretly created at what is now known as Hanford Site in Washington State – using water from the Columbia River in the cooling process – to transform uranium-238 into plutonium for a bomb.

The football field at Susquehanna University is named Amos Alonzo Stagg Field in honor of both Stagg Sr. and Jr. Stagg was the namesake of the University of Chicago's old Stagg Field where, on December 2, 1942, a team of Manhattan Project scientists led by Enrico Fermi created the world's first controlled, self-sustaining nuclear chain reaction under the west stands of the abandoned stadium.

He also created several hundred satiric drawings about the modern way of life under the pseudonym Enrico.

* General Enrico Cialdini, created Duca di Gaeta for his role during the Siege of Gaeta ( 1860 ).

* Enrico Minutoli ( created on December 18, 1389 ) – Cardinal-Bishop of Frascati ; Dean of the Sacred College of Cardinals ; archpriest of the Liberian Basilica ; Camerlengo of the Sacred College of Cardinals

The Duchy of the Archipelago was created in 1207 by Marco Sanudo, a participant in the Crusade and a nephew of the former Venetian doge Enrico Dandolo, who had led the Venetian fleet to Constantinople.

La fanciulla del West was commissioned by, and first performed at, the Metropolitan Opera in New York on 10 December 1910 with Met stars Enrico Caruso and Emmy Destinn for whom Puccini created the leading roles of Dick Johnson and Minnie.

" In the original production of The Sleeping Beauty in 1890, a male dancer, Enrico Cecchetti, created the role of the evil fairy Carabosse, although the role has subsequently been danced by both men and women.

It was where Enrico Fermi created the first self-sustaining nuclear chain reaction under the university's football stadium.

Much of Audio d-Touch was created by Enrico in his spare time as a personal project, ( with collaboration from the aforementioned Robinson, and Simon Shelley, another York alumni ) while the Magic Desk became his Masters project.

* Enrico Mattei, Italian public administrator who created ENI

For example, General Enrico Cialdini was created Duca di Gaeta for his role during the unification.

Enrico Fermi achieved first place in the classification of the entrance exam.

In 1923, while writing the appendix for the Italian edition of the book The Mathematical Theory of Relativity by A. Kopff, Enrico Fermi pointed out, for the first time, that hidden inside the famous Einstein equation (), there was an enormous amount of nuclear potential energy to be exploited.

On 25 January 1939, a Columbia University team conducted the first nuclear fission experiment in the United States, which was done in the basement of Pupin Hall ; the members of the team were Herbert L. Anderson, Eugene T. Booth, John R. Dunning, Enrico Fermi, G. Norris Glasoe, and Francis G. Slack.

The Fermis moved to Chicago in stages that year, and Enrico began studies that led to the construction of the first nuclear pile Chicago Pile-1.

Enrico Fermi had been the first to use a neutron to produce the radioactive change of one element to another.

It was discovered in the debris of the first hydrogen bomb explosion in 1952, and named after Nobel laureate Enrico Fermi, one of the pioneers of nuclear physics.

Hayek's first class at Chicago was a faculty seminar on the philosophy of science attended by many of the University's most notable scientists of the time, including Enrico Fermi, Sewall Wright and Leó Szilárd.

He attended the Liceo classico Cavour in Turin, and enrolled at the University of Turin in 1876, graduating in 1880 with high honours, after which the University employed him to assist first Enrico D ' Ovidio, and then Angelo Genocchi, the Chair of Infinitesimal calculus.

Founded in 1897 as Sport Club Juventus by a group of young Torinese students, among them, who was their first president, Eugenio Canfari, and his brother Enrico, author of the company's historical memory ; they are managed by the industrial Agnelli family since 1923, which constitutes the oldest sporting partnership in Italy, thus making Juventus the first professional club in the country.

In this case, the first experimental atomic reactors would have run away to a dangerous and messy " prompt critical reaction " before their operators could have manually shut them down ( for this reason, designer Enrico Fermi included radiation-counter-triggered control rods, suspended by electromagnets, which could automatically drop into the center of Chicago Pile-1 ).

Lacy's first visit to Europe came in 1965, with a visit to Copenhagen in the company of Kenny Drew ; he went to Italy and formed a quartet with Italian trumpeter Enrico Rava and the South African musicians Johnny Dyani and Louis Moholo ( their visit to Buenos Aires is documented on The Forest and the Zoo, ESP, 1967 ).

Research by Enrico Fermi and others starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war.
