OBJECTIVE Trans-catheter aortic and pulmonary valve replacement procedures can result in favorable outcomes in selected patients. The aim of this study was to investigate the functioning of a novel self-expanding valved stent with super-absorbent polymer (SAP) for minimally invasive replacement of the tricuspid valve. METHODS A newly designed nitinol stent with SAP was specially designed for ...

World population is increasing at an alarming rate, and crop cultivation on marginal lands has emerged as alternate option to feed the burgeoning population. However, are characterized by poor soil health other undesirable characteristics resulting in low production less economic returns. Interest application of superabsorbent polymers (SAPs) for been increasing. The SAPs increases germination ...

BACKGROUND The aim of the present study was to evaluate the hemostatic effect of chitosan linear polymer in a sheep model with femoral bleeding. METHODS Following induction of anesthesia and intubation of sheep, groin injury was induced to initiate hemorrhage. Animals were randomly assigned to study and control groups. In the control group, absorbent pads were packed on the wound, and pressur...

in order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. in this experiment two lev...

Abstract Super-absorbent polymer (SAP) is able to absorb water by multiple times more than its own weight. Sugarcane bagasse (SCB) raw material has been excessively produced as a byproduct in sugar factory. The synthesis of SAP from SCB creates balance between the utilization industrial by-product and resulted environmentally friendly material. In oil production might be troublesome, thus minim...

Polypropylene hollow fiber membrane (PPHFM) contactor, with aqueous solution absorbent such as sodium hydroxide (NaOH), monoethanolamine (MEA) and diethanolamine (DEA), was designed and used to separate and fix CO2 from CO2/N2 gas mixtures. The factors that influence the separation properties of CO2/N2 were investigated. It was found that the CO2 removal efficiency is the best by using MEA solu...

Oil-water emulsion formation is common in oil fields. The a problem which causes an increase production costs and decrease quality. Therefore, demulsifier formulation needed to overcome these problems. use of household waste, particularly disposable diapers, promising alternative. One the substances contained diapers sodium polyacrylate super absorbent polymer, known as polyacrylate. substance ...
