During the 80’s, some experiments and the repetitions of old ones, lead to the hypothesis of a fifth force. Nevertheless, a more accurate research was not able to confirm this hypothesis. This article wants to go over again the most important steps of the event. PACS-01.65.+g History of science. PACS-04.80.Cc Experimental tests of gravitational theories.

a/G(mA +mB) calculated with the system’s parameters, determined independently of the third Kepler law itself, in order to put constraints on some models of modified gravity (f(R), Yukawa-like fifth force, MOND). The major source of error affecting ∆P is not the one in the phenomenologically measured period (δPb = 4× 10 −6 s), but the systematic uncertainty δP (0) in the computed Keplerian one d...

Policy is modeled as the outcome of negotiations between two three-party parliamentary states. An election in jurisdiction A determines the composition of the legislature that selects a representative to negotiate an intergovernmental policy agreement with the representative from the legislature of jurisdiction B. Negotiations are modeled using Nash’s (1950) bargaining framework, modified to ac...

Today, at the beginning of the third millennium, most United Nations (UN) member states2 subscribe to principles and axioms which, textually, appear akin to those precepts which can be found in international covenants, in particular the Universal Declaration of Human Rights of 10 December 1948. However, even constitutions which remain textually close to the UN Declaration gain different meaning...

Occupational Safety and Health Administration (OSHA) computerized inspections data, death certificates, and medical examiner records identified 204 fatal occupational injuries in New Jersey, 1984-85. OSHA computerized data uniquely identified seven cases. They did not identify 35 fatalities under OSHA's jurisdiction, of which 24 were investigated by OSHA but not recorded, four were not consider...
