Electromagnetic Radiation* [PDF]

open access: yes, 1999
Electromagnetic radiation, commonly referred to as light, underpins all spectroscopic techniques, ranging from the highly energetic gamma rays, through x-rays, ultraviolet, visible, infrared, microwaves to the low-energy radio waves. The principles of wave- and particle-like behaviour determine the nature of the radiation and its interaction with ...

Radiation Risks and Mitigation in Electronic Systems [PDF]

open access: yes, 2016
Electrical and electronic systems can be disturbed by radiation-induced effects. In some cases, radiation-induced effects are of a low probability and can be ignored; however, radiation effects must be considered when designing systems that have a high ...

Radiation safety based on the sky shine effect in reactor [PDF]

open access: yes, 2020
In the reactor operation, neutrons and gamma rays are the most dominant radiation. As protection, lead and concrete shields are built around the reactor. However, the radiation can penetrate the water shielding inside the reactor pool.

Numerical approximations for fluid flow and heat transfer in the boundary layer with radiation through multiple Lie similarity transformations

open access: yesFrontiers in Physics, 2023
The dependent or independent variables of differential equations may be reduced by applying its associated Lie point symmetries. Seven-dimensional Lie point symmetry algebra exists for differential equations representing heat transfer in a boundary layer

Radiation in medicine: Origins, risks and aspirations. [PDF]

open access: yes, 2014
The use of radiation in medicine is now pervasive and routine. From their crude beginnings 100 years ago, diagnostic radiology, nuclear medicine and radiation therapy have all evolved into advanced techniques, and are regarded as essential tools across ...

Quality of Life of Oral Squamous Cell Carcinoma Patients before and after Primary Treatment

open access: yesJournal of Pharmacy and Bioallied Sciences, 2023
Background: HNSCC (head and neck squamous cell carcinoma) is a serious global health problem, with estimated more than 550,000 new cases and 300,000 deaths annually. More than 90% of these malignancies are oral squamous cell carcinoma (OSCC).

A scheme for radiation pressure and photon diffusion with the M1 closure in RAMSES-RT [PDF]

open access: yes, 2015
We describe and test an updated version of radiation-hydrodynamics (RHD) in the RAMSES code, that includes three new features: i) radiation pressure on gas, ii) accurate treatment of radiation diffusion in an unresolved optically thick medium, and iii ...

Assessment of public perception of radioactivity in Brazil

open access: yesBrazilian Journal of Radiation Sciences, 2022
Nuclear energy divides public opinion with its “good” and “bad” applications. Almost immediately after the discovery of radiation, radioactive elements purified by the Curies were used in health treatments, but with the nuclear bombs of Hiroshima and ...

The Role of the Human Gut Microbiome in Inflammatory Bowel Disease and Radiation Enteropathy

open access: yesMicroorganisms, 2022
The human gut microbiome plays a key role in regulating host physiology. In a stable state, both the microbiota and the gut work synergistically. The overall homeostasis of the intestinal flora can be affected by multiple factors, including disease ...
