The Role of Ultrasound across the Continuum of Care for Carpal Tunnel Syndrome

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Carpal tunnel syndrome (CTS) is the most common upper limb entrapment neuropathy and a leading cause of pain, functional impairment, and surgical referral. This article demonstrates the central role of ultrasound (US) across the continuum of CTS care, both for confirming the CTS diagnosis and for guiding treatments ranging from perineural injections to

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

open access: yesPolymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

PISTON LUBRICATION IN RECIPROCATING COMPRESSORS

open access: yesRevista de Engenharia Térmica, 2001
Piston dynamics plays a fundamental role in two critical processes related to fluid flow in reciprocating compressors. The first is the refrigerant leakage through the radial clearance, which may cause considerable loss in the pumping efficiency of the compressor.

Academics’ Career Motivations and External Engagement Activity Amid Conflicting Identifications: An Employee Engagement Perspective

open access: yesBritish Journal of Management, EarlyView.
Abstract This paper examines the motivational foundations of academics’ external engagement within the evolving context of the entrepreneurial university. While prior research has explored specific forms of academic entrepreneurship, broader engagement with external organizations has only recently been recognized as both entrepreneurial and value ...
