This paper investigates experimentally the performance of a three-way catalytic (TWC) converter for real-world passenger car driving in the United Kingdom. A systematic approach is followed for the analysis using a Euro-IV vehicle coupled with a TWC converter. The analysis shows that the real-world performance of TWC converters is significantly different from the performance established on legislative test cycles. It is identified that a light-duty passenger vehicle certified for Euro-IV emissions reaches the gross polluting threshold limits during real-world driving conditions. This result is shown to have implications for overall emission levels and the use of remote emissions sensing and on-board diagnostics (OBD) systems.

This paper presents the findings of research into real-world emission levels of a typical EURO-IV passenger car in the United Kingdom (UK). Four real-world drive cycles representing typical urban driving in the UK were used for the experiments. The work identified that the real-world emission levels of a EURO-IV vehicle in the UK are significantly higher than the certified legislative emission levels. The present work also identified that tailpipe-out carbon monoxide is the most affected emission specie in a gasoline-powered vehicle for real-world driving conditions.

Abstract The upper limb activity of twenty unilateral upper limb myoelectric prosthesis users and twenty anatomically intact adults were recorded over a 7-day period using two wrist worn accelerometers (Actigraph, LLC). This dataset reflects the real-world activities of the participants during their normal day-to-day routines. Participants included students, working adults, and retirees recruited from across the United Kingdom. This dataset offers a potential wealth of knowledge into a poorly understood cohort. The raw unprocessed data files and the activity count data exported from the Actilife software are provided. We also provide a non-wear algorithm developed for the removal of prosthesis non-wear periods and resulting activity count data corresponding to prothesis wear periods. Finally, we have included the transposed activity diaries provided by the participants. Analysis to date has primarily involved assessment of the symmetry of upper limb activity, however, there is potential to undertake additional analysis such as understanding the differences in the way a prosthesis is used compared to an anatomical arm.

Sacubitril/Valsartan in now being prescribed by heart failure/cardiology teams across the United Kingdom following the publication of the NICE technology appraisal guidance but is everyone ready for it? This article discusses the practical aspects of what to do and not to do in relation to the drug  based on real world experience from our centre.

The creative and cultural sectors in the United Kingdom largely exclude the working classes. Even the small number of working-class people who do ‘make it’ into these sectors often find themselves and their work badly treated by those who hold the real power. This article explores some of the experiences of working-class artists navigating the cultural sector and how exclusion, prejudice and precarity impacted and continue to impact them. It takes as its focus the filmmaker Alan Clarke and the playwright Andrea Dunbar, who were at the height of their success in the 1980s. It also considers the writers Darren McGarvey and Nathalie Olah, whose work has achieved prominence in recent years. It is through this focus I hope to demonstrate the long continuum of challenges for working-class creatives. This article also considers how, on the occasions when they are allowed the space they deserve, working-class artists have created powerful shifts in cultural production. Finally, it details some of the changes needed for working-class people to be able to take their rightful place in contributing to cultural life and the societal risks involved if they are denied that place.
