Carlos Bertulani
Carlos A. Bertulani is a Brazilian and American theoretical physicist and professor at the department of physics of the Texas A&M University-Commerce. He graduated, PhD, at University of Bonn and works on nuclear physics and nuclear astrophysics. He was formerly a professor at the Federal University of Rio de Janeiro from 1980-2000. Research Bertulani's thesis work on electromagnetic processes in relativistic heavy ion collisions is often taken as the standard reference for gamma-nucleus and gamma-gamma physics in collisions with heavy nuclei. Numerous processes related to lepton-pair (e.g., e+e−, or quark-antiquark) production, and to meson production in Peripheral nuclear collisions were first discussed and proposed in his thesis. The excitation of multiple giant resonances (i.e., a giant resonance on top of another) in nuclei was also a prediction of his thesis work. The excitation of multiple dipole resonances were verified in experiments at the Gesellschaft für Schweri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian People
Brazilians ( pt, Brasileiros, ) are the citizens of Brazil. A Brazilian can also be a person born abroad to a Brazilian parent or legal guardian as well as a person who acquired Brazilian nationality law, Brazilian citizenship. Brazil is a multiethnic society, which means that it is home to people of many ethnic origins, and there is no correlation between one's stock and their Brazilian identity. Being Brazilian is a civic phenomenon, rather than an ethnic one. As a result, the degree to which Brazilian citizens identify with their ancestral roots varies significantly depending on the individual, the Regions of Brazil, region of the country, and the specific ethnic origins in question. Most often, however, the idea of ethnicity as it is understood in the anglophone world is not popular in the country. In the period after the colonization of the Brazilian territory by Portugal, during much of the 16th century, the word "Brazilian" was given to the Portuguese merchants of Brazil ...

YouTube
YouTube is a global online video platform, online video sharing and social media, social media platform headquartered in San Bruno, California. It was launched on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim. It is owned by Google, and is the List of most visited websites, second most visited website, after Google Search. YouTube has more than 2.5 billion monthly users who collectively watch more than one billion hours of videos each day. , videos were being uploaded at a rate of more than 500 hours of content per minute. In October 2006, YouTube was bought by Google for $1.65 billion. Google's ownership of YouTube expanded the site's business model, expanding from generating revenue from advertisements alone, to offering paid content such as movies and exclusive content produced by YouTube. It also offers YouTube Premium, a paid subscription option for watching content without ads. YouTube also approved creators to participate in Google's Google AdSens ...

Beaufort National Cemetery
Beaufort National Cemetery is a United States National Cemetery located in Beaufort County, in the city of Beaufort, South Carolina. Managed by the United States Department of Veterans Affairs, it encompasses , and as of 2014, had over 19,000 interments. History The original interments in the cemetery were men who died in nearby Union hospitals during the occupation of the area early in the Civil War, mainly in 1861, following the Battle of Port Royal. Battlefield casualties from around the area were also reinterred in the cemetery, including over 100 Confederate soldiers. It became a National Cemetery with the National Cemetery Act by Abraham Lincoln in 1863. Of the Civil War soldiers buried here, there are: 9,000 Union soldiers (4,400 unknown,) 2,800 POWs from the camp at Millen and 1,700 African-American union soldiers. There are also 177 confederate soldiers. The remains of 27 Union prisoners of war were reinterred from Blackshear Prison following the war. Beaufort Nat ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...

Physics Today
''Physics Today'' is the membership magazine of the American Institute of Physics. First published in May 1948, it is issued on a monthly schedule, and is provided to the members of ten physics societies, including the American Physical Society. It is also available to non-members as a paid annual subscription. The magazine informs readers about important developments in overview articles written by experts, shorter review articles written internally by staff, and also discusses issues and events of importance to the science community in politics, education, and other fields. The magazine provides a historical resource of events associated with physics. For example it discussed debunking the physics of the Star Wars program of the 1980s, and the state of physics in China and the Soviet Union during the 1950s and 1970s. According to the ''Journal Citation Reports'', the journal has a 2017 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journa ...

Peripheral Nuclear Collisions
High-energy nuclear physics studies the behavior of nuclear matter in energy regimes typical of high-energy physics. The primary focus of this field is the study of heavy-ion collisions, as compared to lighter atoms in other particle accelerators. At sufficient collision energies, these types of collisions are theorized to produce the quark–gluon plasma. In peripheral nuclear collisions at high energies one expects to obtain information on the electromagnetic production of leptons and mesons that are not accessible in electron–positron colliders due to their much smaller luminosities. Previous high-energy nuclear accelerator experiments have studied heavy-ion collisions using projectile energies of 1 GeV/nucleon at JINR and LBNL-Bevalac up to 158 GeV/nucleon at CERN-SPS. Experiments of this type, called "fixed-target" experiments, primarily accelerate a "bunch" of ions (typically around 106 to 108 ions per bunch) to speeds approaching the speed of light (0.999'' ...

Nuclear Astrophysics
Nuclear astrophysics is an interdisciplinary part of both nuclear physics and astrophysics, involving close collaboration among researchers in various subfields of each of these fields. This includes, notably, nuclear reactions and their rates as they occur in cosmic environments, and modeling of astrophysical objects where these nuclear reactions may occur, but also considerations of cosmic evolution of isotopic and elemental composition (often called chemical evolution). Constraints from observations involve multiple messengers, all across the electromagnetic spectrum ( nuclear gamma-rays, X-rays, optical, and radio/sub-mm astronomy), as well as isotopic measurements of solar-system materials such as meteorites and their stardust inclusions, cosmic rays, material deposits on Earth and Moon). Nuclear physics experiments address stability (i.e., lifetimes and masses) for atomic nuclei well beyond the regime of stable nuclides into the realm of radioactive/unstable nuclei, almost t ...
