MY INHALATION CHAMBER.

Design of an Inhalation Chamber to Expose Laboratory Animals with Suspended Particulate Matter by Numerical Simulation Method

Introduction: Usually, in the toxicological studies of airborne particulate pollutants, inhalation exposure chambers are used for providing and distributing the test atmosphere uniformly and stability in the respiratory zone of laboratory animals. The purpose of this study was to design, evaluate and optimize a whole-body exposure chamber, specifically for small laboratory animals exposed to pa...

Generation and homogeneity of aerosols in a human whole-body inhalation chamber.

INTRODUCTION A 16 m(3) whole-body exposure chamber for human exposure to aerosols is described. Several modifications of the aerosol generation and distribution system were needed to ensure a stable aerosol concentration in the chamber, especially when a cyclone pre-classifier was used. RESULTS After these modifications, stable aerosol concentrations of aluminium oxide with a volume median di...

Me, My Echo Chamber, and I: Introspection on Social Media Polarization

Homophily — our tendency to surround ourselves with others who share our perspectives and opinions about the world — is both a part of human nature and an organizing principle underpinning many of our digital social networks. However, when it comes to politics or culture, homophily can amplify tribal mindsets and produce “echo chambers” that degrade the quality, safety, and diversity of discour...
