A comparison between neutron-fluence measurements using metal-activation monitors and standard glasses calibrated via thin uranium-fission monitors and via ηq method
(2013-04-02)
The two fundamental approaches to fission-track dating involve either an explicit determination of the thermal neutron fluence (φ-method) or a calibration against age standards (ζ-method). The neutron fluence measurements ...

In a joint R&D project under the full sponsorship of PETROBRAS, the Brazilian National Oil Company, the first CO2 monitoring field lab was started-up in Brazil in 2011.The site chosen, the Ressacada Farm, in the Southern ...
Review of Procedures and Challenges Associated with an Epidemiological Surveillance of SARS-CoV-2 in Wastewater
(Soc Brasileira Quimica, 2022-03-31)
COVID-19 patients, including asymptomatic, pre-symptomatic and mild cases, were frequently seen to contain in feces and urine samples particles of SARS-CoV-2. Hence, studies to detect the new coronavirus in residual water, ...
Optimization of the atmospheric pollution monitoring network at Santiago de Chile
(Elsevier Ltd, 2003)
Environmental pollution is a problem affecting many cities in our planet. Santiago de Chile is one with the worst indices. Because of that, local authorities implemented a few years ago an air quality monitoring network ...
