Although wafer-level camera lenses are a very promising technology, problems such as warpage with time and non-uniform thickness of products still exist. In this study, finite element simulation was performed to simulate the compression molding process for acquiring the pressure distribution on the product on completion of the process and predicting the deformation with respect to the pressure ...
BACKGROUND Neurovascular compression of the rostral ventrolateral medulla, a major center regulating sympathetic nerve activity, may be causally related to essential hypertension. Microvascular decompression of the rostral ventrolateral medulla decreases elevated blood pressure. CASE DESCRIPTION A 47-year-old male essential hypertension patient with hemifacial nerve spasms exhibited neurovasc...
Effects of ankle-to-knee external pressures on skin blood perfusion under and distal to compression.
OBJECTIVE To compare the effects of select leg compression pressures on blood perfusion in the skin overlying bone and the skin distal to the leg compression. DESIGN Blood perfusion of skin overlying the tibia and the foot dorsum was simultaneously measured in 12 healthy subjects using laser Doppler. Each subject's calf was compressed from ankle to knee with an air cast that applied external ...
Trends in Textile Engineering & Fashion Technology Mathematical Approach for the Prediction of Compression Pressure Hafiz Faisal Siddique* Technical University Liberec, Clothing Technology, Czech Republic *Corresponding author: Siddique, Submission: February 02, 2022; Published: March 03, 2022 DOI: 10.31031/TTEFT.2022.06.000642 ISSN 2578-0271 Volume 6 Issue 4
BACKGROUND The effects of surgical pneumoperitoneum on lower-limb venous hemodynamics have already been studied; however, the effects of intermittent compression boots are not known in such venous-stasis conditions. METHODS In 12 volunteers and 12 patients, the venous hemodynamic effects of intermittent leg compression were studied under external abdominal pressure or during laparoscopic chol...
