Fractional Euler-Lagrange modeling of a pendulum with a vertically vibrating pivot

This study develops classical and fractional variational models for a simple pendulum whose pivot undergoes prescribed vertical harmonic motion. The nonlinear classical equation of motion and its small-angle, Mathieu-type reduction are first derived from the Euler-Lagrange equati...

Influence of fin geometry on heat transfer and friction in plate fin heat exchangers: a CFD approach

Abstract Plate fin heat exchangers (PFHEs) are widely recognized for their compact design and high thermal efficiency, making them a popular choice in various heat transfer applications. Some common types of geometries which are used in the case of PFHEs are rectangular fins, tri...

Occupational strain and post-retirement rehabilitation among older factory workers

Background Long-term factory work involves repetitive, physically demanding tasks that contribute to musculoskeletal degeneration in later life, particularly affecting the knee and cervical spine among ageing workers. Qualitative evidence on how retired industrial workers perceiv...

Circulating microRNAs: a new era in early detection of oral squamous cell carcinoma (OSCC) — a systematic review and meta-analysis

BACKGROUND: The chances of oral squamous cell carcinoma (OSCC) being diagnosed at an early stage are very low, and this leads to a poor prognosis. The presence of circulating miRNAs (miRNAs) in blood or saliva is now a potential non-invasive diagnostic biomarker, although the dia...

Effects of Proprioceptive Neuromuscular Facilitation-Based Reformer Pilates and Hatha Yoga on Functional Fitness, Balance, and Cognitive Performance in Older Women: A 16-Week Randomized Controlled Trial

Abstract Background Aging is associated with progressive declines in neuromuscular function, postural control, and cognitive performance, which may compromise functional independence. Mind–body exercise approaches such as Pilates and Yoga have been suggested as effective strategi...

Interactive influence of in-situ annealing temperature and thermal processing parameters on defect minimization and strength enhancement in FDM-printed PEEK
