Space-shaping through rhythmic interventions for teaching and learning: pedagogical perspectives
No full textSpace-Shaping Through Rhythmic Interventions for Teaching and Learning: Pedagogical Perspectives
Get PDFWe explore the challenges and opportunities relevant to rhythmanalytical approaches in teaching and learning through two socio-spatial and design-oriented courses with graduate and undergraduate students. Through the courses we investigate how different understandings and analyses of rhythms-through-space in comparison to rhythms-in-space generate different patterns of interventions. We also share prospects for preparing and structuring future teaching and learning that integrate time-sensitivity through constructively aligned activities supporting the development of different forms of knowledge. This work supports recent calls for greater attention to how temporality and particularly rhythms could be better understood, observed, framed, and conveyed. In the foreground is the need to improve how we guide students' research through design-oriented learning experiences. For this we provide frameworks bringing together concepts from rhythmanalysis and constructive alignment. We draw on comparative and case study experiences from 2022 and the winter of 2023/2024 involving interdisciplinary bachelor-level and master-level courses, respectively. Our cases wrangle with the relationships between socio-spatial and temporal scales that steer or constrain rhythmic patterns expressed in students' analyses and design interventions. From an instructional standpoint, this contribution poses the question: Which conceptual structures in design-oriented pedagogy could support rhythmanalytical approaches and capacities for future spatial planners and designers? Our final reflections discuss opportunities for improvement and evaluate how future planning pedagogy research and work could build on our experiences
City Rhythm: logbook of an exploration
Get PDFRhythm is fundamental to life. Rhythm can be perceived in the movement of the sun, the moon and the stars. Rhythm makes our hearts tick and defines our breath, in and out. And even the smallest particle in a microbe is part of rhythmic movements. Rhythm in activities is important for culture, for religion, and for sports, schools and hospitals for example. Yet in social situations, social analyses and in social policymaking, rhythm is not considered as a space of analyses or a space of design. City Rhythm explores the potential of using rhythm analyses in the physical world and related data domain for enhancing social safety in neighbourhoods in the Netherlands. Rhythm in the physical world happens both in space as well as in time. Rhythm in data can connect to location (instead of persons), thus circumventing the issue of privacy. However, because the data addresses specific times and places, nonetheless the data still addresses significant social issues. Founded in the social sciences, humanities, arts and computer science, the interdisciplinary research team also includes civil servants of six cities in the Netherlands who have engaged throughout the research. With the help of students, nine case studies are carried out. Building upon methodologies from the social sciences and architecture, it is found that in seven cases rhythm analyses identified new design solution spaces. As a result, a methodology for doing rhythm analyses in the physical world is developed. More theoretical and artistic explorations are carried out. These enable the bridging of experience and insight from rhythm analyses to the data world. The interdisciplinary research team formulates the basic concept and terminology for the City Rhythm Data Model (CRDM). This consists of beats, base and street rhythms. Beats are defined by the state of specific area at a specific moment in time, As an example of a state, a street might have lots of cars, few cars, or no cars at all. Street rhythms show significant transitions over time for the specific area. The base rhythm of an area is defined by comparison to other areas. These derived rhythms are like a musical meter. In this specific context, individual street rhythms develop. Street rhythms represent a variation around a few specific themes. The City Rhythm Data Model (CRDM), based on mixtures of hidden Markov models, is built and run with open and linked data from the Central Bureau for Statistics (CBS) of the Netherlands. Areas can be represented using sizes in different datasets. City Rhythm worked with areas of 500 by 500 meters. The choice of datasets is defined by mapping upon the YUTPA framework which indicates trade-offs for trust. In the validation session of the City Rhythm Data Model it is concluded that the general experience of social safety of specific areas is reflected in CRDM base rhythms. For being able to understand which specific data constitute a beat (or “state”) and for understanding specific street rhythms, further research is necessary. In conclusion to the one year exploratory study, City Rhythm indicates that rhythm analyses, in the physical world as well as in the related data domain, offer a potential new approach for policymaking
Chromatin modifications of hTERT gene in hTERT-immortalized human mesenchymal stem cells upon exposure to radiation
No full textRegulation of telomerase activity is thought to participate in the cellular response to ionizing radiation. Epigenetic mechanisms play a role in this regulation, as well as other mechanisms such as transcription, phosphorylation, etc. Here, we investigated chromatin modifications in telomerase promoter upon exposure to ionizing radiation in human mesenchymal stem cells (hMSC) and telomerase-immortalized hMSCs (hMSC-telo1) together with a hMSC-telo1 cell line in which TRF2 expression was partially repressed (siTRF2 hMSC-telo1). Histone methylations and acetylations were compared in all cell lines after exposure to various doses of ionizing radiation (0.1, 1, 2.5 and 15 Gy) using chromatin immunoprecipitation assay. hTERT gene was shown to be quickly regulated through H3, H4 acetylations, as well as with H3K4 and H3K9 methylations, following radiation exposure, although the kinetic of hMSC-telo1 cells were different, indicative of the higher radioresistivity of these cells. To the author's surprise, there was an upregulation of endogenous telomerase activity in the hMSC-telo1 cells, even though the cells had already expressed high levels of ectopic hTERT. Our results show that telomerase regulation is one of the primary actions in response to damage and epigenetic factors play a major role in this regulation. Our results also suggested that partial silencing of TRF2 enhances the radiosensitivity of these cells, and endogenous telomerase is upregulated upon radiation, even under ectopic expression of hTERT in these cells

Feasibility of Bolted Connectors in Hybrid FRP-Steel Structures
No full textDue to the low weight and excellent durability of composite materials, Fibre Reinforced Polymer (FRP) decks mounted on steel superstructures are becoming all the more common in engineering practice. Bolted joints are generally used to facilitate connections between an FRP deck and steel girders in road bridges. The connections are subjected to both high magnitude static forces as well as fatigue loading due to overpassing vehicles. With ever increasing traffic on both road and railway bridges, fatigue performance is of critical concern. Bolted FRP joints have been extensively researched in the past under static loading, but less is known about the fatigue and creep behaviour of such joints. Furthermore, little research exists on non-pultruded FRP profiles connected using bolted connections. Therefore, the objective of this research is to investigate connectors’ feasibility by means of static, fatigue and creep experiments on four different types of bolted joints comprising mechanical connectors and injection techniques. The study focuses on application in vacuum infused GFRP panels with integrated webs made of multi-directional laminates, connected to steel bridge superstructures. In addition, experimental results are validated by Finite Element Analyses (FEA). Based on the obtained results, the novel injected steel-reinforced resin (iSRR) connector developed at TU Delft shows promising potential in hybrid steel-FRP bridges where good fatigue endurance of the connection and local loads in FRP panel, are required.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Steel & Composite Structure
