Vibrations

Particulièrement sensibles aux modifications du taux d’humidité, les chats le sont aussi à l’augmentation de la charge d’électricité statique, aux infra et aux ultra-sons, aux variations brusques du champ magnétique, l’accroissement des vibrations du sol d’où probablement leur faculté de pressentir, avant les humains, certains phénomènes naturels comme orage, tempête, cyclone, tremblement de terre ou éruption volcanique. On a vu des chats détaler hors des bâtiments dans les minutes qui

Currently, the complaints caused by noise increase day -to-day, due to certain factors, such as: electronic equipment, more numerous and potent; exposed, and without proper treatment, building facades; little isolation of the used materials; vibrations transmitted through the structures; etc. The problems due to poor acousti c performance are, in general, complex. When there aren’t concerns in the design stage, the solutions, in majority, require large financial investment. This paper

there is a reduction on the intensities of the bands assigned to lignin, mainly those at 1730 cmÀ1 (carbonyl groups) (Pandey & Pitman, 2003; Tserki, Zafeiropoulus, Simon, & Panayiotou, 2005). Other important bands are: 1512 cmÀ1 (aromatic ring vibrations of phenylpropane skeleton) and 1250 cmÀ1 (aryl–alkyl ether linkage) (Pandey & Pitman, 2003; Tejado, Pena, Labidi, Echeverria, & Mondragon, 2007; Yang, Yan, Chen, Lee, & Zheng, 2007).

Blasting was monitored by a seismograph in order to control vibrations near edifications, allowing blasting diagram to be improved. Índice Índice ................................................................................................................................... i Índice…

cultures are absorbing a variety of knowledge and habits acquired in its relationship with the environment which they live. Among these cultures, the AfroBrazilian religions make worship to Africans gods and use plants in the rituals, in searching for vibrations and irradiation of energy, for therapeutic and mystic purposes, as offerings to spiritual entities. The study was realized in five fields at the East Zone (neighborhoods of Nova Brasília and José Pinheiro) of Campina Grande city,…
