Vibrations

1995). Without a shelter they are presumably more vulnerable than U. reversalis when resting. Vespid wasps are important predators of medium-sized caterpillars however, and many species even have mechanoreceptive hairs with maximum sensitivity to vibrations at the wingbeat frequency of such predatory wasps (Tautz & Markl, 1978). M. sexta can be controlled in tobacco fields by vespids (Rabb & Lawson, 1957). Feeding times of caterpillars in general are probably constrained by the dangers of…

aimed to describe a methodological expertise developed during the course of Experimental Analysis of Structures, taught in the second half of 2007 in the Polytechnic School of Sao Paulo. Their approach, within the content, was the analysis of vibrations in structures. However, it has proposed the study of the vibration caused by people walking on a bridge, whose board was prepared by using many sensors in order to obtain consistent data to validate a model made by the technique of…

very widely used in the present time for its low cost, great praticity and sensitivity. The diverse audible pulmonary sounds give health professionals important spots of pulmonary conditions to guide the treatment. These sounds results from lung vibrations and their airways transmited to the chest surface. They can first be divided in: bronchial (traqueobonchial) or vesicular, not existing standardization in its description. The aim of this review is to show what exists about…

that deals with environmental control; it discriminates impacts that mining can cause in the community that is inserted, as referring to water resources, soil changes and vegetation of the area, interactions in air quality, promoting of sounds and vibrations and, socioeconomic conditions of the community who suffer interference from mining companies. Finally, it relates in a directed way, the main environmental impacts caused by the exploration of uranium in the municipality of Caetité,…

In order to clarify the mode of bonding, the Infra Red (IR) spectra of these complexes were recorded. The following discussion is confined to the most important vibrations in 350 – 4000 cm-1 region. In the IR spectra, the characteristic absorptions of oxalato-bridged group, the ligands, N– M–N bonding (M=Fe) and O–M–O bonding (M=Cr) were observed. For the oxalate ligand, the strong νas…
