Radio-quiet quasars in the VIDEO survey : evidence for AGN-powered radio emission at S-1.4 GHz<1 mJy
(2015-04-11)Understanding the interplay between black-hole accretion and star formation, and how to disentangle the two, is crucial to our understanding of galaxy formation and evolution. To investigate, we use a combination of optical ... -
The Radioactive Nuclei 26Al and 60Fe in the Cosmos and in the Solar System
(2021-12-09)The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter recurrently re-processes metal-enriched stellar ... -
Radiofrequency-based treatment in therapy-related clinical practice – a narrative review. Part I : acute conditions
(2015-08-01)Background: Radiofrequency electromagnetic field (RFEMF or simply RF)-based electrophysical agents (EPAs) have been employed in therapy-related clinical practice for several decades. They are used to reduce pain and ... -
Radiofrequency-based treatment in therapy-related clinical practice – a narrative review. Part II: chronic conditions
(2016-02-09)Background: Radiofrequency (RF)-based electrophysical agents (EPAs) have been employed in therapy related clinical practice for several decades. They are used to reduce pain and inflammation and promote tissue healing. ... -
Radiogenic p-isotopes from type Ia supernova, nuclear physics uncertainties, and galactic chemical evolution compared with values in primitive meteorites
(2014-11-10)The nucleosynthesis of proton-rich isotopes is calculated for multi-dimensional Chandrasekhar-mass models of Type Ia supernovae (SNe Ia) with different metallicities. The predicted abundances of the short-lived radioactive ... -
Radiographer reporting : Origins, demise and revival of plain film reporting
(2001-01-01)Important in a profession's identity is the knowledge of past events and how they help shape the present. This article traces the socio-political aspects of one significant aspect of radiographic history, the origins, ... -
The radiographers' role in information giving prior to consent for computed tomography scans: A cross-sectional survey
(2016-06-25)Purpose Computed tomography (CT) use has increased in recent years with concerns regarding radiation risk. Informed consent requires that patients are informed of risks and benefits; however, it is known that radiation ... -

Radiological Demonstration of Small Bowel Adaptation following a Modified Scopinaro Procedure for Morbid Obesity
(1993-05)Upper gastrointestinal contrast studies were carried out on 24 patients at progressive time intervals following gastric partition with partial biliopancreatic bypass (modified Scopinaro procedure) for morbid obesity. ... -
Radiosonde aerosol counter for vertical profiling of atmospheric dust
(2010)A low-cost, miniature aerosol particle counter has been developed, intended for use with balloon-borne meteorological radiosondes. It is particularly suitable for airborne mineral dust measurements. Ambient air is drawn ... -
The RADIOSTAR Project
(2022-02-17)Radioactive nuclei are the key to understanding the circumstances of the birth of our Sun because meteoritic analysis has proven that many of them were present at that time. Their origin, however, has been so far elusive. ... -
A rain tower and wind tunnel for studying the dispersal of plant pathogens by rain and wind
(1986-12)The rain tower/wind tunnel complex at Rothamsted consists of a rain tower (height 11 m, cross-section 1 m2) linked to the upwind end of a wind tunnel (length 12 m, cross-section 1 m2), which may be operated in either an ... -
