Trial By Steam: A Lesson Plan For Using “Repent, Harlequin!” In The Steam Classroom, Olivia Burgess

The Transdisciplinary STEAM+ Journal

This lesson plan uses Harlan Ellison’s “Repent, Harlequin! Said the Ticktockman” as part of an interdisciplinary first-year curriculum linking perspectives from the humanities with engineering design. Students participated in a “mock trial” based on two characters from the story as a way to reflect on good teamwork, the value of creativity, and on the nature of the engineering profession. Both Ellison’s story and the lesson explore the benefits of taking a “STEAM” perspective that integrates the precision and timeliness needed in engineering (represented by the Ticktockman) with the flexibility and creativity inspired by the humanities (represented by Harlequin).

What Can We Learn About Research Narratives From Professional Storytellers?, Kim Wilkins, Helen Marshall

The Transdisciplinary STEAM+ Journal

This short note on practice reflects on how “research narrative” is a much-used, but misunderstood term. Compelling stories about our research are important: for public-facing communications and for academic tenure confirmation and promotion. They are also important for researchers to gain a clearer sense of their own vision and values in the research process: they are not just a communication skill, they’re a career skill. But often researchers in STEM disciplines do not have the practical skills to write stories. We draw on our own practice as creative writers to share some simple and effective methods to bring arts expertise …

Corrosion Of Coated And Uncoated Steel Reinforcement In Concrete, Jana Abou Shakra, Rouba Joumblat, Jamal Khatib, Adel Elkordi

BAU Journal - Science and Technology

Corrosion of reinforcing steel is the one of the main causes of deterioration in reinforced concrete structure. During the initial stage of corrosion, the steel volume increases. This creates tensile stresses in the concrete, which can eventually lead to cracking, delamination, and spalling. This potential risk of corrosion in a structure is quite unpredictable. Therefore, this paper examines the influence of accelerated corrosion on the bond between concrete and the coated and uncoated steel bars. The bar coating consisted of epoxy rich in zinc. Six concrete mixes were prepared. Three mixes had cement contents of 300, 400 and 500 Kg/m3 …
