Unified field theory of (the not mathematically well-defined) quantum electrodynamics. One can extend this system to include the weak and strong nuclear forces to get the Einstein–Yang–Mills–Dirac System. The French physicist Marie-Antoinette Tonnelat published a paper in the early 1940s on the standard commutation relations for the quantized spin-2 field. She continued this work in collaboration with Erwin Schrödinger after World War II. In the 1960s Mendel Sachs proposed a generally covariant field theory that did not require recourse to renormalisation or perturbation theory. In 1965, Tonnelat published a book on the state of research on unified field theories. In 1963 American physicist
Unified settlement planning and Planning - 2032, on 18 & 19 April 2012. The seminar has strongly recommended that the development of rural and urban settlements in India should not be planned separately. The fundamental objective for a unified settlement plan includes: The strategies for achieving the objectives include: Unified settlement planning Unified settlement planning (USP) is the component of regional planning where a unified approach is applied for a region's overall development. The USP approach is most often associated with urban planning practices in India. Regions use their land in for various purposes, including agriculture, manufacturing, and public administration.
