Graham's law has come to denote an important class of finely divided materials. Around the time Graham did his work, the concept of molecular weight was being established largely through the measurements of gases. Daniel Bernoulli suggested in 1738 in his book Hydrodynamica that heat increases in proportion to the velocity, and thus kinetic energy, of gas particles. Italian physicist Amedeo Avogadro also suggested in 1811 that equal volumes of different gases contain equal numbers of molecules. Thus, the relative molecular weights of two gases are equal to the ratio of weights of equal volumes of the gases. Avogadro's insight together with
Same-sex marriage in the Republic of Ireland for lesbians, gays and bisexuals, which highlighted the lack of recognition for same-sex couples in Irish law. In a departure from the norm, the report recommended legislative changes. These were to give legal recognition to same-sex couples, to provide equality with married couples in the areas of adoption, inheritance and taxation to eliminate discrimination. NESF: In April 2003, the National Economic and Social Forum (NESF) published Report 27. The implementation of equality policies for gay, lesbian and bisexual people. The recommendations included calls for the Law Reform Commission to consider models to achieve equal rights for same-sex couples in its
