Background: Late side effects of head and neck cancer treatment commonly affect swallowing function. Late radiation-associated dysphagia (late-RAD) often presents years post-treatment when patients have been discharged from their multidisciplinary team. Timely symptom management may provide important physical and emotional support, potentially…

This article considers to what degree the UK depends on nuclear power for the generation of electricity and examines the problems, environmental and technical, associated with radioactive waste. Historical failings, the waste backlog, classification, modern handling techniques and with decisions about final disposal are outlined to provide an…

The Timepix hybrid silicon pixel detector has been used to investigate the inverse square law of radiation from a point source as a demonstration of the CERN [at] school detector kit capabilities. The experiment described uses a Timepix detector to detect the gamma rays emitted by an [superscript 241]Am radioactive source at a number of different…

Sense About Science is a UK-based charitable trust that equips people to make sense of science and of evidence on issues that matter to society. It was set up in 2003 in response to newspaper front pages being full of headlines about mobile phones "frying your brain", genetically modified "Frankenstein foods", the MMR vaccine,…

Information and communication technology (ICT) is a natural part of most people's everyday life, and has also been introduced in schools. Previous studies have tended to focus on issues related to competency of teachers and lack of computer technology in schools. Focus now seems to be moving towards studies that help us understand how ICT may be…

A computer model of the decay of a radioactive series, written in Visual Basic in Excel[TM], is presented. The model is based on the random selection of cells in an array. The results compare well with the theoretical equations. The model is a useful tool in teaching this aspect of radioactivity. (Contains 4 figures.)

Joseph Rotblat was one of the most distinguished nuclear physicists and peace campaigners of the post Second World War period. His peace activities rank alongside those of Albert Einstein and Bertrand Russell; he won the Nobel Peace Prize, jointly with the Pugwash movement, that he helped found. However, he made significant contributions to…

Aims: To compare voice quality as defined by formant analysis using a sustained vowel in patients who have undergone a partial glossectomy with a group of normal subjects. Methods & Procedures: The design consisted of a single centre, cross-sectional cohort study. The setting was an Adult Tertiary Referral Unit. A total of 26 patients (19…

This textbook is a course on properties of heat. The first seven lectures of the course deal with "thermometric heat" and its generation and consumption in mechanical processes; the determination of the mechanical equivalent of heat; the conception of heat as molecular motion; the application of this conception to the solid, liquid, and…

Documents a quasi-scientific comparative study of two groups of 'recent school leavers' in the UK. Studies non-science university undergraduates and explores whether people living with the immediacy and relevance of higher-than-average levels of radioactivity were more knowledgeable and emotionally detached than a similar group removed from this…

Research on conceptual change emphasizes the importance of factors in the cognitive domain. This research argues that models of conceptual change learning should also encompass issues of affect, conation, and self-esteem. The use of these expressions is explained via four case studies on members of a rural village concerning informal learning…
