Energetic, exergetic, economic and environmental (4E) assessment of power cycles integrated with anaerobic digester
No full textAs the world struggles with climate change, biogas produced via anaerobic digestion (AD) offers a promising sustainable energy solution. While numerous studies have explored integrating AD with heat-to-power generation systems, a key gap remains in understanding how biomass affects overall system performance. In particular, through comprehensive energy, exergy, economy, and environmental (4E) assessments which are essential for a more accurate system modelling, and system optimization. To address this gap, this research evaluated five biogas-powered configurations: gas turbine cycle (GT), organic Rankine cycle (ORC), ORC with an internal regenerator (ORC-IG), supercritical carbon dioxide (SCO2), and SCO2 with a recuperator (SCO2-R). These systems were assessed and compared based on energy and exergy efficiency, total annual cost, CO2 emissions, and CO2 equivalent emission. Among them, the GT-SCO2-R system delivered the best overall performance, achieving the highest thermal and exergy efficiencies (44.33% and 43.0%, respectively), maximum net power output (11,078 kW), the shortest payback period (1.72 years), and the greatest CO2 emissions reduction (13,515 tCO2/year). It also compares alternative waste management methods and outlines critical factors for policymakers. The analysis also revealed that the digestion plant caused the highest exergy destruction, indicating the need for technological improvements at this stage. This study contributes to a deeper understanding of biogas system performance and provides valuable insights into design optimization. It also compares alternative waste management methods and outlines critical factors for policymakers. The findings support the strategic advancement of biogas as a viable path toward sustainable energy production

Navigating Statutory Homelessness Support:Impacts of Asylum and Refugee Policy
No full textHomelessness among newly recognised refugees in the UK is not an inevitable outcome, but the product of policy decisions and systemic barriers that compound people’s vulnerability at the very point when stability is most needed. People emerge from the asylum process with a view to rebuilding their lives but face abrupt transitions, fragmented support and a hard-to-navigate housing landscape, even for long-term residents. The consequences negatively impact people’s chances of securing economic and social stability. The report discusses evidence on how asylum and immigration policies have combined with housing market pressures to exacerbate the likelihood of homelessness for newly recognised refugees. Decades of policy reform, spanning dispersal, outsourcing, restrictions on employment, and the Right to Rent have systematically undermined refugees’ ability to develop social networks, sustain themselves financially, and build the knowledge needed to secure housing. These long-standing constraints have produced conditions in which homelessness is not incidental but foreseeable. Against this context, the report calls for a more responsive, coordinated and humane approach to homelessness among new refugee
Perceptions of Far-Right Extremist Violence as Terrorism:Exploring Influences on Public Perception in the United Kingdom
No full textThis article presents the results of an empirical inquiry into the complex dynamics of public perception of Far-Right Extremism (FRE). The instrument of data collection was an online questionnaire which produced a rich dataset comprising both quantitative and qualitative data. This study investigates the extent to which the United Kingdom’s (U.K.) public associates Far-Right violence with terrorism and whether media consumption, trustworthiness of media reporting of FRE incidents and social identity—age, gender and ethnicity—influence whether individuals attribute a terrorist label to FRE case studies. Statistical analyses revealed a significant relationship between Social Media and TV News Programmes consumption and the trustworthiness of TV News, Tabloid and Broadsheet Newspapers reporting on the labelling of several FRE incidents as terroristic or not. Statistical analysis also revealed that respondents’ age and gender significantly influenced whether three of the four case studies were classified as acts of terrorism, whereas ethnicity had no impact. The research advances the current depth of understanding on labelling of FRE incidents as terrorism by conducting a much-needed empirical investigation and elucidating the diverse range of influences on public perception of FRE.</p
Enhancing Industrial Collaborative Robots Inverse Dynamic Model for Application in Fault Detection:A Hybrid Approach
No full textAn accurate dynamic model of industrial collaborative robots is needed for condition monitoring applications, such as in the detection of early faults or anomalies. Due to the complex and coupled nature of cobots, their modelling is challenging and easily prone to errors. These errors can be linked to simplifying assumptions made during the model formulation, like unchecked kinematic errors, the linearization of the dynamic equations, unaccounted load, incorrect friction model, non-exciting trajectory, etc. This paper presents different techniques of modelling a UR10e cobot offline, ranging from physics-based models to data-driven methods and model enhancement through a hybrid approach. The prediction performance of these techniques was compared, and the hybrid model yielded the best overall accuracy for the two test trajectories examined. Moreover, the hybrid model developed has the potential to be deployed in model-based condition monitoring for the early detection of cobot faults.</p
The influence of career guidance and open days on first-generation students’ university choices
No full textThis article sets out to investigate the role of career guidance and university open days in shaping the higher education choices of first-generation students. Using Careership as a theoretical framework (Hodkinson, Hodkinson & Sparkes, 1996, Hodkinson & Sparkes, 1996, Hodkinson, 2009), it draws on qualitative data from surveys conducted across three post-16 education providers and semi-structured interviews with first-generation students and staff. Thematic analysis reveals that while university is often viewed as a natural next step for these students, opportunities for career guidance to expand their horizon for action are frequently missed or not recognised. In-person open days emerge as pivotal moments in a first-generation student’s decision-making by offering critical ‘turning points’ that influence both what and where they choose to study
Town Island:A Pre-Show Interview with Artist Benaiah Matheson
No full textArtist Benaiah Matheson presented Town Island at the Venice Biennale (20 April-24 Nov 2024) working in partnership with Yorkshire Contemporary. Now, together with Huddersfield Art Gallery, and the University of Huddersfield, Matheson brings the exhibition to The Sovereign Design House (25 Jan–22 March 2025) at the University of Huddersfield. Using a Blended Curatorial approach the Huddersfield iteration of Town Island brings new work, interpretations, and a participatory programme to explore how the themes of co-creation, dual-identity and belonging connect to health and wellbeing, as part of the Cultures of Creative Health Programme (2024)
Strange Attractor:The Hallucinatory Life of Terence McKenna
No full textA stand-up philosopher who made a unique contribution to science, humanism, and the hidden arts, Terence McKenna (1946-2000) was the twentieth century's psychedelic Renaissance man. Perfecting his rugged philosophy on the role of psychedelics in evolution, consciousness, and time, McKenna was a riotous charmer who stalked the shadows, but also sought the iridescence. More than twenty years since his untimely passing, McKenna has an enduring magnetism across the virtual pop stream, in pervasive digitization, and within social media networks. In Strange Attractor, the first biography of this enigmatic figure, Graham St John detects the signal behind the noise. This book is an engaging chronicle of the life, works, and legacy of this brazen adventurer of the inner and outer dimensions, whose weird intelligence has affected multitudes and whose spirit continues to haunt the present. It draws on original documents and letters, features fifty two rare photographs and artworks, and shares previously untold stories from over eighty people. Neither glorifying nor disparaging its subject, Strange Attractor will appeal to those interested in the evolution of a psychedelic intellectual, and to those for whom McKenna's wisdom endures.</p
