Influence of urban form on air quality: The combined effect of block typology and urban planning indices on city breathability.

Urban morphology affects airflow, causing pollutant accumulation within the urban canopy. Urban planning can regulate urban form by applying such strategies as defining urban block typology and stipulating urban indices. Consequently, urban planning can contribute to a healthy environment.

Characterization of the indoor particles and their sources in an Antarctic research station.

Many studies have been carried out on the environmental impact of the research stations on the Antarctic continent. However, the assessment of indoor air quality in these confined environments has been neglected. The main objectives of this study are to investigate the granulometric distribution of the indoor particles in the different compartments of the Brazilian Antarctic Station, to examine the number and mass concentration of the indoor particles, to conduct chemical and morphological analyses of the indoor PM2.

[Rudolf Barth: a pioneering scientist on the island of Trindade].

As a result of the institution of the International Geophysical Year in 1957, the Brazilian Navy organized an expedition to the island of Trindade, on which Rudolf Barth participated. He was a researcher at the Oswaldo Cruz Institute and the Naval Research Institute, and a member of the Brazilian Academy of Sciences and the National Research Council. The scientist returned to the island of Trindade the following year, on a second expedition with the Brazilian Navy.
