2. Effect of traffic noise on Scinax nasicus advertisement call (Amphibia, Anura)
ABSTRACT Increased anthropogenic-made sounds such as traffic noises contribute to acoustic pollution, which produces deleterious effect on song-vertebrates. We compared the advertisement call of Scinax nasicus (Cope, 1862) males in natural (as a reference or control, Site A) and Sites affected by traffic noises (Site B). Call structure was recorded and it wa

3. Perception of Noise Pollution in a Youth and Adults School in Curitiba-PR
Abstract Introduction Nowadays noise remains the third largest cause of environmental pollution on Earth. It appears that despite the existing noise control legislation the issue deserves further supervision by the public authorities so that the ceilings established for the various activities are observed. People exposed to noise are more likely to develop

4. Slag Foaming Fundamentals - A Critical Assessment
Slag foaming is part of steelmaking process and could bring several benefits: it helps to save energy, improves productivity, enhances the refractory service life, decreases noise pollution and protects the bath from nitrogen incorporation. Unfortunately, slag foaming is a highly dynamic process that is difficult to control. There are factors that limit the

5. Acoustical performance of porous absorber made from recycled rubber and polyurethane resin
This paper reports an investigation of a new kind of material and its acoustical performance. The main component of this porous absorber is the ground tyre rubber (GTR) with different particle sizes, from the shredding of tyres of heavy vehicles, mixed with different proportion of polyurethane resin. Acoustical properties were assessed according to ISO 10534

7. Impacto ambiental de kartódromos situados na cidade do Rio de Janeiro: monitoramento de BTEX no ar e do nível de ruído
In this work, noise and aromatic hydrocarbons levels of indoor and outdoor karting circuits located in Rio de Janeiro were assessed. The sampling was perfomed using active charcoal cartridges, followed by solvent desorption and analysis by gas chromatography with mass spectrometry detection. This study demonstrated that the karting circuits, venues for enter

9. AVALIAÇÃO DO RUÍDO DE TRÁFEGO VEICULAR EM ÁREA CENTRAL DE CHAPECÓ SC / EVALUATION OF VEHICULAR TRAFFIC NOISE IN CENTRAL ZONE CHAPECÓ SC
The development of cities and population growth have led, among other urban problems, the increase in sound pressure levels of environmental noise. With the overcrowding of cities, the roads start to host large flows of vehicles, among other sound sources. These factors, coupled with the layout and massing of buildings, make the road a polluter responsible f

11. Estudo da influência dos parâmetros no processo de soldagem GMAW - arco pulsado
Pulsed gas metal arc welding describes the metal transfer mode involving oscillation (pulsing) of the welding current from a high pulse current in which level drop growth, necking of wire tip and detachment occur, and a low background current, which is applied to maintain the arc. The advantages of the process are: metal transfer without spatter formation an
