Even if the mechanical performances of composite materials give new perspectives for the aircraft and space design, the variability of their behavior, linked to the presence of initial microscopic defects or led in service, constitute however a still important brake in their development. As regards particularly the response to fatigue loads or ageing, the behavior of these materials is affected...

Filling time and volume fill prediction of long complex parts produced using the method resin infusion is prominent importance. Fibre fraction, reinforcement type composite laminate thickness significantly affect manufacturing behaviour. It crucial to have an estimate fabrication parameters such as filling time. The PAM-RTM (resin transfer moulding) commercial software package makes it possible...

Introduction Nanocontact molding and other related techniques of imprint lithography have received much attention as potentially simple and inexpensive tools for the accurate replication of sub-100 nm features. We have recently reported on the use of this method for the replication of features as a small as 60 nm. In this technique, an inexpensive mold is made by curing a photopolymer resin aga...

background: debonding of denture teeth from denture bases is the most common failure in removable dentures. the purpose of this study was to evaluate the effect of surface treatments on shear bond strength of denture teeth to heat-polymerized and autopolymerized denture base resins. materials and methods: in this experimental in vitro study, 60 maxillary central incisor acrylic teeth were divid...

Hemolytic uremic syndrome (HUS) is a life-threatening infectious disease in childhood for which there is no confirmed therapeutic strategy. Endothelial inflammation leading to microthrombosis formation via complement activation is the main pathology of HUS. Thrombomodulin is an endothelial membrane protein that has anticoagulation and anti-inflammatory effects, including the suppression of comp...

Hemophagocytic lymphohistiocytosis (HLH) is a fatal disease, presenting with T cell-induced dysregulated cytokine production, systemic inflammation, and frequently intractable coagulopathy. We have administered recombinant human soluble recombinant thrombomodulin (rTM) for four cases of severe childhood Epstein-Barr virus-associated HLH (EBV-HLH) in combination with anti-inflammatory therapy an...

BACKGROUND The non conventional RTM (Restricted Tobacco etch virus Movement) resistance which restricts long distance movement of some plant viruses in Arabidopsis thaliana is still poorly understood. Though at least three RTM genes have been identified, their precise role(s) in the process as well as whether other genes are involved needs to be elucidated. METHODOLOGY/PRINCIPAL FINDINGS In t...

We report a significant advance in space robotics design based on innovation of 3D composite structures and piezoelectric actuation. The essence of this work is development of a new all-composite robotic manipulator utilizing rotary ultrasonic motors (USM). “MarsArmII“ is 40% lighter than a prior “MarsArmI” JPL design based in more massive, bulky hybrid metal-composite, joint-link system archit...

This research was conducted to investigate the bond strength between artificial teeth and a thermoplastic denture base resin for injection molding with different surface preparations use in flexible removable partial dentures. Composite acrylic were bonded three types of resins (polyamide, polyester, polycarbonate) conventional heat-polymerized polymethyl methacrylate (PMMA) (control). The ridg...
