Statistical approach for human electromagnetic exposure assessment in future wireless ATTO-cell networks [PDF]

open access: yes, 2019
In this article, we study human electromagnetic exposure to the radiation of an ultra dense network of nodes integrated in a floor denoted as ATTO-cell floor, or ATTO-floor. ATTO-cells are a prospective 5 G wireless networking technology, in which humans

Development of a land use regression model for black carbon using mobile monitoring data and its application to pollution-avoiding routing [PDF]

open access: yes, 2020
Black carbon is often used as an indicator for combustion-related air pollution. In urban environments, on-road black carbon concentrations have a large spatial variability, suggesting that the personal exposure of a cyclist to black carbon can heavily ...

Workplace Exposures [PDF]

open access: yesClinics in Colon and Rectal Surgery, 2019
AbstractWorkplace exposure in colorectal surgery is unique compared with other surgical specialties and generally underreported. Although the most common device-associated exposure in surgery is suture needle injury, colorectal surgeons are increasingly exposed to gastrointestinal-related infectious agents, radiation, and other hazards in multiple ...

Distribution and Causes of Global Forest Fragmentation

open access: yesEcology and Society, 2003
Because human land uses tend to expand over time, forests that share a high proportion of their borders with anthropogenic uses are at higher risk of further degradation than forests that share a high proportion of their borders with non-forest, natural ...
