Filtration Of Nanoparticles Applied In General Ventilation, Clothilde Brochot, Pooya Abdolghader, Fariborz Haghighat, Ali Bahloul

Études primaires

Nanoparticles (NPs) are particles with a diameter less than or equal to 100 nm. Because of their size, they pose a major challenge to workers’ health and safety. General ventilation is one of the solutions in order to minimize both occupational and general exposure.

In North America, ventilation filters are tested according to ANSI/ASHRAE Standard 52.2 and rated according to their efficiency results as a function of particle diameter. The most penetrating particle size (MPPS) is commonly accepted as being 300 nm, but it no longer represents the worst-case scenario in terms of particle diameter and filter penetration.

Exposure to occupational carcinogens is often overlooked as a contributor to the burden of cancer. To estimate the proportion of cancer cases attributable to occupational exposure in Canada in 2011, exposure prevalence and levels of 44 carcinogens were informed by data from the Canadian carcinogen exposure surveillance project (CAREX Canada). These were used with Canadian Census (between 1961 and 2011) and Labour Force Survey (annual surveys between 1976 and 2013) data to estimate the number of workers ever exposed to occupational carcinogens. Risk estimates of the association between each carcinogen and cancer site were selected mainly from published literature reviews. …

Dr. Tele-Corporation: Bridging The Access-To-Care Gap, Nader Amer

Dickinson Law Review (2017-Present)

The United States is currently confronting an access-to-healthcare crisis, which rural regions are experiencing at a disproportionate rate. Many commentators have touted telemedicine as a solution for the access-to-care issue. Telemedicine uses video and telecommunication technology to allow physicians to treat patients from distant locations and thus facilitates a more equal distribution of physicians throughout the United States.

Although the telemedicine industry is quickly growing, the corporate practice of medicine doctrine impedes the industry’s expansion and consequently obstructs a viable solution to the access-to-care crisis. Generally, the corporate practice of medicine doctrine prohibits corporations and limited liability companies from employing …
