2025 Personal-sized Seedless Watermelon Cultivar Evaluation in Indiana
No full textIndiana ranks fifth in the United States for watermelon production in 2024. Most of the state’s production consists of red-flesh seedless cultivars with fruit weighing 9 lbs and above. A small portion of watermelon production devoted to mini seedless types. Meanwhile, interest in watermelon production among small and diversified vegetable farms is increasing, where smaller-sized watermelons are likely fit better at these farms. In this report, we summarize the performance of 12 personal-sized watermelon cultivars evaluated at the Southwest Purdue Agricultural Center (SWPAC) in Vincennes, IN, during the 2025 season
Book Review of Coloring and Learning about Cambodia in the Arts: Learning about Cambodia in the Arts
No full textI have long been witness to the silence that trauma leaves behind. I understand how the body remembers what the tongue cannot say. The aftermath of genocide and displacement leaves not only human tragedy but also artistic ones: a fracture in how we imagine, how we create, how we see. For those of us shaped by the Cambodian diaspora, what we can’t express in words lives through art: through lines and colors. Cambodian classical dance shows this clearly: each gesture tells a story without words and that art has always been our language
Markets We Thought We Knew
No full textMarkets We Thought We Knew explores the evolving nature of markets and how they shape—and are shaped by—consumer behavior. From essential life necessities such as water to everyday commodities and products including locally sourced foods, this book covers a variety of topics and invites readers to examine a diverse range of markets through a reflective lens. By revisiting past market dynamics and real-world examples, readers are encouraged to rethink how preferences are formed, how opinions shift over time, and how value is assigned—sometimes in unexpected ways. What insights might you gather from a deeper understanding of local and global markets, markets for water, or even markets for something you may have never considered valuable, such as carbon? Markets We Thought We Knew challenges assumptions and inspires fresh thinking about marketplaces, both near and far.https://docs.lib.purdue.edu/purduepress_ebooks/1091/thumbnail.jp
Impact of Slot Liner Compression on the Total Thermal Resistance of the Stator-Winding Assembly in Electric Motors
No full textThe increasing demand for high-performance electric motors, driven by the rapid adoption of electric vehicles, necessitates effective thermal management techniques that improve their safety, efficiency, and reliability. Heat must be transferred from the current-carrying copper windings to the metallic stator body through an electrically insulating material called the slot liner. However, little research has focused on the interactions between the slot liner and the windings. This study examines the impact of slot liner compression on the thermal resistance across the stator-winding assembly considering two common slot liners: Nomex® 410 and Kapton® MT+. A mock stator-winding assembly was developed by stacking a grooved copper piece that mimics the windings, a slot liner, a rigid silicon piece that imitates the stator, and a reference material used to quantify heat flow. Steady-state temperature gradients are induced across the stack, infrared (IR) microscopy captures the resulting two-dimensional temperature maps, and the total thermal resistance across the assembly is calculated. Tests are repeated at several levels of compression. With increasing compression, the area-normalized thermal resistance of the winding-stator interface with a Nomex® 410 slot liner decreases by 14.9% (from 94 to 80 cm2K/W) and, with Kapton® MT+, it decreases by 68.0% (from 50 to 16 cm2K/W). This research provides insight into the effects of slot liner material and compression level on the thermal management of electric motors. Reducing the total thermal resistance reduces temperatures within the windings, resulting in longer component lifespans and more efficient motors
