Rotary drums are used to manufacture pharmaceuticals, cement, food, and other particulate products because of their high heat and mass transfer rates. These processes are governed by particle parameters, such as particle size, particle distribution, and shape, and operating parameters, such as rotation rate and fill level. Enormous energy savings are possible with further research in rotary drums due to potential increases in operating efficiency. This study investigates the drum rotation rate on particle bed temperature at temperatures above 500 °C to see the role that radiation heat transfer plays in this process. 2 mm silica beads and a stainless steel rotary drum were used at a fill level of 25% with rotation rates from 2-10 rpm. A new setup and procedure were developed using heating coils and an IR camera to reach high temperatures. The inner drum wall temperature exceeded the outer drum wall temperature because the steel transmitted more heat into the drum at higher temperatures. Although it was unclear whether the heat transfer rate was affected by the increasing rotation rate, the highest final average particle temperature was obtained at 5 rpm. The particle bed temperature distribution narrowed as the rotation rate increased because, at higher rotation rates, more particles are in contact with the drum wall than at lower rotation rates.

On 15 April 1999, physician Gillian Thomas published the editorial “Improved Treatment for Cervical Cancer – Concurrent Chemotherapy and Radiotherapy,” henceforth “Improved Treatment,” in The New England Journal of Medicine. In that editorial, she discusses the potential benefits of combining chemotherapy drugs with radiation to treat women with cervical cancer. At the time, healthcare professionals rarely treated cervical cancer by combining chemotherapy or radiation. Two months prior to Thomas’s publication, the US National Cancer Institute, headquartered in Bethesda, Maryland, released an announcement advocating for combining chemotherapy with radiation based on clinical trial results. In “Improved Treatment,” Thomas summarized the results of those clinical trials that had led to the announcement and communicated a new way to treat invasive cervical cancers, which persists as of 2019.

In 2003, HBO Original Programming released the documentary Chernobyl Heart. Maryann De Leo directed and produced the film, which is about the Chernobyl nuclear power plant accident and how the radiation from that accident has affected people living in the area. Side effects have included mental disabilities, physical disabilities, and genetic mutations. The documentary follows Adi Roche, the founder of Chernobyl Children International, a non-profit humanitarian organization headquartered in Cork, Ireland, as she interviews people who live in the areas that Chernobyl contaminated with radiation. Roche travels to mental asylums, hospitals, and orphanages to interview people who take care of the children affected by the radiation. Chernobyl Heart provided viewers with information about the side effects of radiation exposure and the long-term effects that this has on people, especially children exposed to radiation during their developmental years.
