Zaira Ollano
Zaira Ollano (1904–1997) was an Italian physicist, researcher and professor. She investigated physics and nuclear physics, including the radiation absorption properties of beryllium. Life and work Ollano was born in Cagliari, the capital of Sardinia, Italy, on 4 March 1904, to Francesco and Felicina Statzu (or Stazu). Cagliari She graduated in physics at the University of Cagliari, "probably in 1926," and remained there as an assistant in experimental physics until 1936. When the department chair died in 1928, physicist Rita Brunetti from Ferrara, Italy assumed that position and for many years, Ollano and Brunetti collaborated to advance concepts in physics. In 1929, Brunetti and Ollano developed an experiment to verify, for the first time, the Stark-Lo Surdo effect on a solid compound, determining the order of magnitude of the intramolecular electric field in didymium compounds. Also in 1929, the two physicists began investigating Raman scattering, which had been disco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cagliari
Cagliari (, also , , ; sc, Casteddu ; lat, Caralis) is an Italian municipality and the capital of the island of Sardinia, an autonomous region of Italy. Cagliari's Sardinian name ''Casteddu'' means ''castle''. It has about 155,000 inhabitants, while its metropolitan city (including Cagliari and 16 other nearby municipalities) has more than 431,000 inhabitants. According to Eurostat, the population of the Functional urban area, the commuting zone of Cagliari, rises to 476,975. Cagliari is the 26th largest city in Italy and the largest city on the island of Sardinia. An ancient city with a long history, Cagliari has seen the rule of several civilisations. Under the buildings of the modern city there is a continuous stratification attesting to human settlement over the course of some five thousand years, from the Neolithic to today. Historical sites include the prehistoric Domus de Janas, very damaged by cave activity, a large Carthaginian era necropolis, a Roman era amphith ...

Hydronium
In chemistry, hydronium (hydroxonium in traditional British English) is the common name for the aqueous cation , the type of oxonium ion produced by protonation of water. It is often viewed as the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, ) to the surrounding water molecules (). In fact, acids must be surrounded by more than a single water molecule in order to ionize, yielding aqueous and conjugate base. Three main structures for the aqueous proton have garnered experimental support: The Eigen cation, which is a tetrahydrate, H3O+(H2O)3; the Zundel cation, which is a symmetric dihydrate, H+(H2O)2; and the Stoyanov cation, an expanded Zundel cation, which is a hexahydrate: H+(H2O)2(H2O)4. Spectroscopic evidence from well-defined IR spectra overwhelmingly supports the Stoyanov cation as the predominant form. For this reason, it has been suggested that wherever possible ...

Academic Staff Of The University Of Pavia
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Cagliari Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A ...

Free University Of Brussels (1834–1969)
The Free University of Brussels (french: Université libre de Bruxelles, or ULB; nl, Vrije Hogeschool te Brussel, later ''Vrije Universiteit Brussel'') was a university in Brussels, Belgium. Founded in 1834 on the principle of "free inquiry" (''libre examen''), its founders envisaged the institution as a free-thinker reaction to the traditional dominance of Catholicism in Belgian education. The institution was avowedly secular and particularly associated with Liberal political movements during the era of pillarisation. The Free University was one of Belgium's major universities, together with the Catholic University of Leuven and the state universities of Liège and Ghent. The "Linguistic Wars" affected the Free University, which split along language lines in 1969 in the aftermath of student unrest at Leuven the previous year. Today two institutions carry the "Free University of Brussels" name: the French-speaking Université libre de Bruxelles (ULB) and the Dutch-speaking Vr ...

Meson
In particle physics, a meson ( or ) is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one femtometre (10 m), which is about 0.6 times the size of a proton or neutron. All mesons are unstable, with the longest-lived lasting for only a few hundredths of a microsecond. Heavier mesons decay to lighter mesons and ultimately to stable electrons, neutrinos and photons. Outside the nucleus, mesons appear in nature only as short-lived products of very high-energy collisions between particles made of quarks, such as cosmic rays (high-energy protons and neutrons) and baryonic matter. Mesons are routinely produced artificially in cyclotrons or other particle accelerators in the collisions of protons, antiprotons, or other particles. Higher-energy (more massive) ...

University Of Pavia
The University of Pavia ( it, Università degli Studi di Pavia, UNIPV or ''Università di Pavia''; la, Alma Ticinensis Universitas) is a university located in Pavia, Lombardy, Italy. There was evidence of teaching as early as 1361, making it one of the oldest universities in the world. It was the sole university in Milan and the greater Lombardy region until the end of the 19th century. In 2022 the University was recognized by the Times Higher Education among the top 10 in Italy and among the 300 best in the world. Currently, it has 18 departments and 9 faculties. It does not have a main campus; its buildings and facilities are scattered around the city, which is in turn called "a city campus." The university caters to more than 20,000 students who come from Italy and all over the world. The university offers more than 80 undergraduate programs; over 40 master programs, and roughly 20 doctoral programs (including 8 in English). About 1,500 students who enter the university every ...
