Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

PISTON LUBRICATION IN RECIPROCATING COMPRESSORS

Revista 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.

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

Journal 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
