Effects of artificial substratum types and exposure time on macroalgal colonization in a tropical stream
(E Schweizerbart'sche Verlags, 2010-09-01)
This study examines the development of the macroalgal community in a tropical stream on different artificial substrata (material and surface texture) and over varying periods of time. Our study indicated that the physical ...
Effect of inhalation exposure to toluene on the activity of organic anion transporting polypeptide (Oatp) using pravastatin as a probe drug in rats
(2018-07-03)
1. Toluene, used as a pure substance or in solvent mixtures, is the cause of occupational exposures of large numbers of workers in the world. The organic anion transporting polypeptides (OATP: human; Oatp: rodents) are ...
The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
The influence of thermal comfort conditions on user’s exposure time in open spaces
(2019-01-01)
This paper discusses the influence of the user thermal comfort conditions on the time spent in open spaces through a case study performed in Bauru, Sao Paulo, Brazil. The study was carried out in two subspaces of a zoo, ...

Behavioral observation used to estimate pesticide exposure for farm workers in Brazil
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2009)
Assessment of the harm caused by exposure to pesticides requires that a measure of exposure be available. While such information is available without difficulty in controlled laboratory studies, estimating the exposure of ...
