Demore Barnes (born February 26, 1976) is a Canadian actor. Barnes is best known for his roles as Sergeant First Class Hector Williams in the CBS military action television series The Unit, the archangel Raphael in Supernatural and Deputy Chief Christian Garland in Law & Order: Special Victims Unit.
Sergeant First Class Hector Lucian Williams (United States Army, call sign: Hammerhead) (portrayed by Demore Barnes) was a Unit operator assigned to Alpha Team of the 1st Special Actions Group (official cover as the "303rd Logistical Studies Group"). He was an experienced marksman, and frequently served as a sharpshooter for the team.
The first season of The Unit originally aired between March 7, 2006 and May 16, 2006, it introduces the members of The Unit and their families. As the season progresses various plots and story arcs are explored, such as Tiffy Gerhardt's affair with Colonel Tom Ryan and Molly Blane's mission to find the army widow who conned her out of her savings.
The second season of The Unit originally aired between September 19, 2006 and May 8, 2007; it introduces several new characters to the series. Tiffy has trouble with the law when she covers for Colonel Ryan's wife, Charlotte, and The Unit is investigated by the CIA over infractions that could result in criminal charges.
In nuclear physics, a beta decay transition is the change in state of an atomic nucleus undergoing beta decay.When undergoing beta decay, a nucleus emits a beta particle and a corresponding neutrino, transforming the original nuclide into one with the same mass number but differing atomic number (nuclear charge).
The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence; for example, solid transitions to liquid with an increase in temperature. Near absolute zero, a substance exists as a solid.
If the nucleus is assumed to be spherically symmetric, an approximate relationship between nuclear radius and mass number arises above A=40 from the formula R=R o A 1/3 with R o = 1.2 ± 0.2 fm. [6] R is the predicted spherical nuclear radius, A is the mass number, and R o is a constant determined by experimental
When nucleons bind together to form a nucleus, they must lose a small amount of mass, i.e. there is a change in mass to stay bound. This mass change must be released as various types of photon or other particle energy as above, according to the relation E = mc 2. Thus, after the binding energy has been removed, binding energy = mass change × c ...
