The main objective of this research is to manufacture expanded perlite (EP) foam-filled stainless steel tubes for energy absorption application and investigate their physical compressive behavior. Foam-filled (FFT) were manufactured by consolidating perlite/sodium silicate composite foam inside the tube. EP particles size 5-6 mm taken manufacturing FFTs. Two different sodium solution water (S/W...

This study presents a novel shock absorber with an inward-inverting composite foam-filled tube. Under the compression of pressing cap and action internal inversion cap, tube inverted inward. During crushing, fronds compacted foam, thereby enhancing energy absorption. Three types foams were applied to absorber, drop-weight impact test was performed obtain assessment parameters. The foam increase...

A method to obtain the local heat transfer coefficients of carbon dioxide at supercritical pressures in vertical multi-port mini-channels and in a vertical small tube under cooling conditions was presented through the combination of experiments and numerical simulation in this paper. The CFD code FLUENT 6.1 was used to simulate the convection heat transfer of cooling water to determine the loca...

conclusions after kyphoplasty, her pain was immediately resolved, vertebral body height was restored to normal, and pain score was reduced from 8 to 1. she was discharged with a normal neurological examination and good general condition, and returned to her normal life. in this case, balloon kyphoplasty resulted in the restoration of the vertebral body height, decrease in pain, and returning to...

In this paper, we propose an adaptive predictive coding method based on image segmentation for lossless compression. MAR (Multiplicative Autoregressive) predictive coding is an efficient lossless compression scheme. Predictors of the MAR model can be adapted to changes in the local image statistics due to its local image processing. However, the performance of the MAR method is reduced when app...

Simple hepatic cysts are a relatively common radiological finding. These cysts may be classified as parasitic and non-parasitic. They are usually asymptomatic, but may cause symptoms due to local compression. These compressive complications include: portal hypertension, edema due to caval compression, extrinsic gastric compression and duodenal compression with obstruction.However, no reports in...

INTRODUCTION In Japan, expiratory rib cage compression (a chest physiotherapy technique) is frequently used with mechanically ventilated patients. It has not been determined whether rib cage compression combined with endotracheal suctioning improves oxygenation, ventilation, and mucus clearance. We evaluated the effects of rib cage compression with and without endotracheal suctioning on P(aO(2)...

This article examines the performance of Carbon Fibre Reinforced Polymer (CFRP) on Concrete Filled with Vinyl Chloride Tube (CFPT) columns under axial compression. Firstly, 44 CFPT specimens from literature were analyzed using ABAQUS software to understand compressive behavior applied displacement. Secondly, 268 are simulated influence CFRP these control a varying number FRP layers and wrapping...

INTRODUCTION Expiratory rib cage compression is a chest physiotherapy technique known as "squeezing" technique in Japan. It has been claimed that rib cage compression effectively treats and/or prevents lung collapse, but no studies have been reported on rib cage compression focused on improving ventilation and/or oxygenation in subjects with collapsed lung. Therefore, we studied whether rib cag...
