The Biomechanical Impact of Slipper Sole Compliance on Lumbar Spine Load: A Quantitative Analysis of Indoor Footwear Ergonomics
Abstract: Abstract The global shift toward remote work has significantly increased the duration of indoor footwear usage, yet the ergonomic standards for slippers remain critically under-researched compared to athletic or industrial footwear. While "high-compliance" or soft slippers are traditionally marketed for immediate comfort, excessive mechanical softness may lead to foot instability, altered gait kinetics, and subsequent compensatory stress on the lumbar spine. This study aims to quantify the correlation between varying …

Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …
