13. Efeitos intra-uterinos e pós-natais da exposição crônica ao combustível diesel sobre o aparelho reprodutor humano / Intrauterine and postnatal effects of chronic diesel exhaust exposure on the female reproductive tract
INTRODUÇÃO. Os efeitos da poluição atmosférica sobre a saúde humana são cada vez mais reconhecidos. A exposição ao combustível diesel, que contribui significativamente para a poluição em zonas de tráfego veicular intenso, pode ser ao menos parcialmente, responsável por estes efeitos. Estudos epidemiológicos demonstram maior incidência de pré

16. Numerical evaluation of an air-to-air missile radar cross section signature at X-band
Abstract: The remote detection of a vehicle requires that some kinds of its emissions are tracked and detected. Usually, electromagnetic emissions are used in the form of radar (electromagnetic waves in the range of radiofrequency and microwaves). Different types of antennas are used as sensors, tailored to the signal frequency band and its polarization, as

17. A review of low-level air pollution and adverse effects on human health: implications for epidemiological studies and public policy
The aim of this study was to review original scientific articles describing the relationship between atmospheric pollution and damage to human health. We also aimed to determine which of these studies mentioned public policy issues. Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the Pu
