Automated classification of plant water status through morpho-kinematic monitoring of plant movement
No full textPlant motion provides valuable indicators of physiological responses to water stress. In this study, we present a structured image-based approach to define and test morpho-kinematic (MK) traits from lettuce plants subjected to varying irrigation regimes under controlled conditions. Four water availability treatments were imposed − Full Control (FC), Stress Control (SC), Mild Stress (SM), and Severe Stress (SS) − varying in timing, frequency, and intensity of irrigation protocols.
Using dense optical flow on time-lapse RGB images, we extracted MK features that link leaf age to motion dynamics. These high-dimensional temporal features were compressed into descriptive and trend-based characteristics for classification. Multi-classification problem was divided into nine sub-tasks, for which feature selection and multiple machine-learning models were tested applying Leave-One-Sample-Out cross-validation. The best models were organised into four explainable hierarchical cascades.
The presented system captures enough information to successfully distinguish among subtle differences in plants’ response to water availability dynamics (best architecture cascade obtained 0.93 out of fold balanced accuracy). The framework associating leaf age with MK features along with feature engineering allowed explainability – e.g., central rosette’s features were selected almost twice the expected frequency (19 out of 58) in tasks involving the stress-adapted control (SC), while features capturing linear trends in motion were generally selected over twice as often as simple descriptive statistics (44 vs. 19), proving essential for distinguishing most stress conditions.
The MK approach proved effective for differentiating water stress levels, positioning it as a powerful tool for digital phenotyping and a solid foundation for developing advanced temporal-aware models

Maintenance and Restoration of Open Habitats
No full textTwo-thirds of the Wytham Estate consists of open habitats such as semi-natural grassland, wetland, or productive farmland. Many plant species declined as farming became more intensive during the 1950s; other open habitats were lost to scrub through lack of grazing. Monitoring the restoration of plant communities on different soils across the Estate shows that initial changes in species richness are rapid, but some specialist species may take decades to reappear. Ant research shows that these may be keystone species in dry grassland. Changing rainfall patterns (from climate change) and flood regimes (from river management) alter the recovery trajectory. Lowered water tables, eutrophication, and lack of disturbance led to fen areas becoming dominated by tall competitive plants; felling trees in the catchment and regular cutting has helped reverse those changes. Regenerative agriculture is starting to increase local biodiversity on the farmland
Examining anomalous summer carbonyl sulfide emissions in a boreal forest after thinning
No full textCarbonyl sulfide (COS) is gaining interest as a proxy for gross primary productivity (GPP). Thinning of the Hyytiälä (Finland) forest in the winter of 2019–2020 altered the response of COS fluxes to environmental conditions in the summer of 2021. For the first time, extended periods of ecosystem-scale COS emissions were observed in a boreal forest. The warm and dry conditions in the summer of 2021 reduced the COS uptake by the canopy and elevated soil abiotic COS production. However, the reduction in canopy uptake and the increase in soil production do not fully explain the observed ecosystem-level emissions. The analysis suggests an unidentified, homogeneously distributed COS source in the eddy covariance footprint area, potentially from the photodegradation of forest floor litter and cutting residue from thinning. Such a source in a boreal forest stand warrants further source apportionment studies to effectively use COS as a proxy for GPP
Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids
No full textCutting fluids play a crucial role in dissipating the heat generated during machining operations, contributing to improved service life and machinability of tools and workpieces. Even though commercially available conventional cutting fluids are effective in serving their intended roles during the machining process, they are non‐biodegradable. Previous researchers have introduced a variety of environmentally friendly alternatives, among which green cutting fluids stand out due to their biodegradability and availability. The present study focuses on a comparative assessment of the machining performance of green cutting fluids, made from oil‐water emulsions derived from coconut oil, sunflower oil, and palm oil, with a conventional cutting fluid (MAK Sherol B) during the turning operation of AISI 304 stainless steel. Tween 20 is used as the emulsifying agent for preparing oil‐water emulsion. The machining performance was investigated by examining the impact of these cutting fluids on cutting speed, feed rate, and depth of cut on tool tip interface temperature, surface roughness, and cutting force during the turning process. Surface roughness values are determined using surface profilometry and Atomic Force Microscopy (AFM). The results indicate that palm oil has rendered the lowest cutting force and cutting temperature with improved surface quality under higher feed rates, cutting speeds, and depths of cut as compared with sunflower oil, coconut oil, and conventional cutting fluid
‘The Music of the Band’: music and mental wellbeing in the nineteenth century
No full textThis paper explores the notion of music as a therapy within the psychiatric institutions that dominated mental health care in nineteenth-century Britain. It opens with some key background and questions around the ‘power’ of music, as well as the ways in which music was utilised in insane asylums during the period. At the core of the paper is a poem by poet John Reid Adam, or ‘Iram’ (), ‘Song – Music a Mental Medicine’, which depicts a man within one of the asylums whose melancholy is lifted by the experience of the dance. The poem not only contrasts the grief and woe of the man prior to the dance with his uplifted spirits and revitalised behaviour; it also hints at a longer-term beneficial effect. I will conclude the paper with reflections on the ways in which the impact of music portrayed in the poem are echoed in modern-day contexts
Music and sound in documents: a case study of music and asylum history
No full textThis chapter asks key questions about tracing music and sound in documentary archive materials, and the ways in which considering musical worlds and soundscapes adds a new dimension to historical and documentary research.
The idea of ‘archival silence’ has become an important metaphor for scholars of critical archive studies, in turn offering new perspectives on what is, and what isn’t, accessible in archive and documentary collections. Using the term ‘archival silence’ more literally provokes questions about the ways music and sound can be investigated and explored via documents. The chapter will open with a number of key questions about what aspects of musical practice can be examined using documents, and how this, in turn, can enhance understandings of musical performance and experience. It also addresses the limitations of documentary evidence, exploring the range of sources available for studying music and the questions and gaps which often remain. I draw on creative and imaginary approaches to suggest ways in which these can be probed.
The second part of the chapter focusses on the case study of music and the asylum. My recent research has drawn on a range of archive and document collections to examine the scope and role of music in the nineteenth-century asylum. I outline the key archival sources, critical approaches to using these to build up a picture of musical experience, and the limits and bounds to my project.
Finally, I reflect on the potential importance of considering music and sound as key elements of documentary studies beyond music. The fleeting nature of aurality, and the difficulty of capturing aural experience, both mean that sound and music are frequently absent from both historical and contemporary research. This section builds on recent research to emphasise the key role of aural experience in critical documentary research, as well as the role of musicological studies in broader interdisciplinary contexts
Developing reflective practice in Initial Teacher Education: A collaborative approach to toolkit design
No full textThis Praxis Scholarship project explored the pivotal role of critical reflection in shaping the professional development of student teachers throughout their PGCE. A review of literature informed the evaluation of widely used reflection models and methods, alongside the skills, attributes, and barriers that influence effective reflective practice.
Using a mixed methods design the study drew on qualitative and quantitative data gathered from an online survey, during two workshops, student teachers’ written reflections, and during the collaborative process of the creation of two new models and supporting resources.
The findings highlight how the student teacher / teacher educator partnership reveals areas of the PGCE programme that could be refined to strengthen reflective practice. Conversations with others were reported as being significant for student teachers, yet using a combination of approaches is particularly effective. Reflecting on practice is viewed as an opportunity to ‘see what works‘ / ‘to improve’, however, finding time to reflect can be challenging. Key features necessary for reflective models to be effective were identified and informed the co-creation of two new reflective models to be piloted with student teachers.
The project outcomes include a renewed understanding of the purpose of critical reflection, co-constructed reflection models with supportive prompts, and an interactive toolkit to enhance and sustain reflective engagement for all PGCE partners
