The 150th Anniversary of I. M. S.
We cannot let the January number of the Gazette which, for 48 years, lias represented the work and the interests of the Indian Medical Service, go to press without recalling to our readers the interesting fact that The Indian Medical Service takes its date as a regular medical establishment with fixed grades, and definite rules for promotion from grade to grade from 1st January 1764, or 150 yea...
متن کاملCelebrating the 150th anniversary of the National Academy of Sciences.
On March 3, 2013 the National Academy of Sciences will be 150 years old. Its creation in 1863 represents part of a dramatic series of federal actions that positioned the United States of America for a bright future. In 1862, Congress passed and President Lincoln signed the Morrill Act, creating Land Grant Colleges, providing federal land grants for the use of the new colleges and allowing the l...
متن کاملOn the occurrence of metallic character in the periodic table of the chemical elements.
The classification of a chemical element as either 'metal' or 'non-metal' continues to form the basis of an instantly recognizable, universal representation of the periodic table (Mendeleeff D. 1905 The principles of chemistry, vol. II, p. 23; Poliakoff M. & Tang S. 2015 Phil. Trans. R. Soc. A 373: , 20140211). Here, we review major, pre-quantum-mechanical innovations (Goldhammer DA. 1913 Dispe...
متن کاملAn extraordinary testimonial of thermal rehabilitation: Giuseppe Garibaldi - 2011: 150th Anniversary of the Italian Unification.
On the occasion of the 150th Anniversary of the Italian Unification, the discovery of some letters by Giuseppe Garibaldi - referring to a period of thermal treatments at the Baths in Civitavecchia (Rome) - gave us the opportunity for writing a commentary about a not well known experience in the Two World Hero's life: the numerous treatments carried out at many Italian spa centres for treating a...
متن کاملSuperconductivity and the periodic table: from elements to materials.
Based on the normal-state electronic band structure, the necessary condition for a metal to become a superconductor is the simultaneous occurrence of flat and steep bands at the Fermi level. The sufficient condition at least for conventional superconductors is a strong enough coupling of the flat band states to the lattice, e.g. via phonons. Selected elements (Te) and compounds of the rare eart...
