Considering the surface roughness of piston ring and cylinder liner and deformation of cylinder liner, the friction dynamics calculation model of cylinder liner-piston ring friction pair was established.The effects of top ring, other piston rings and cylinder liner surface roughness on friction performance were analyzed by grouping comparison and B
In this explorative study, we investigated motives of Dog Blankets autonomous learners to participate in an online course, and how these motives are related to gameplay motivations, engagement in the course experience, and learning outcomes.The guiding premise for the study has been the idea that learning and game playing carry phenomenal similarit
In the present work studies were carried out to extract a cationic dye (Methylene Blue MB) from an aqueous solution using emulsion liquid membrane process staff (ELM).The organic phase (membrane phase) consists of Span 80 as emulsifier, sulfuric acid solution as stripping agent and hexane as diluent.In this study, important factors influencing the
Background/Objectives: To compare the lumbopelvic muscle mechanical properties (MMPs) of women with and without multiple sclerosis (MS) and explore relationships between these properties and sociodemographic/clinical characteristics.Methods: This cross-sectional observational study included 22 women with MS and 22 age- and BMI-matched women without
