pokkari
O comportamento do xido n trico (NO) em sistemas biol gicos vem sendo explorado desde a descoberta de sua import ncia em processos regulat rios, fisiol gicos e tamb m em patologias. Por isso, atualmente h o grande interesse no estudo e desenvolvimento de compostos que possam liberar NO de forma controlada para fins farmacol gicos. Compostos nitrosilos de metais t m sido pesquisados neste cen rio, onde os complexos de rut nio est o entre os mais estudados devido ao fato de poderem atuar como doadores ou captadores de NO frente a est mulos qu micos ou fotoqu micos. Nesta vertente, os compostos que t m atra do bastante aten o frente s suas propriedades s o aqueles que possuem como ligantes: aminas, derivados de aminas e azamacrociclos, que s o geralmente sol veis em gua e est veis em solu o. Exemplos desta classe de compostos de rut nio s o as tetraminas de rut nio(II) contendo piridina (ou derivados) e NO como ligantes axiais. Estes complexos liberam NO quando irradiados. Neste contexto, este livro apresenta considera es sobre a libera o fotoqu mica de xido n trico, sensibilizada por corantes, a partir de um nitrosilo de rut nio.

Construction Industry not only provides employment to the large population but has direct link with the economy also. Construction industry being second largest in India after Agriculture, contributes about 11% in the GDP. Although steel, wood Aluminium structures are also in use, concrete structures are the most common type of structures. From industries to highways from dams to flyovers massive concrete structures are occupying their place in the world. Cement industry isdirectly related with the construction industry in the world. India is the second largest cement producer in the world after China. For making concrete and mortar which are two main components of concrete structure sand is invariably used. Sand has its natural origin as it is produced by degradation of natural rocks due to abrasion. As demand of natural sand is increasing day by day there is heavy thrust on the environment and suitable alternatives shall be used in place of naturalsand to protect and preserve the environment.
