Point of care testing (POCT) as part diseases and health monitoring will be very beneficial in resource constrained areas with minimum healthcare expert power requirement. Elimination external source device brought the idea self-powered infusion micropump. This research aimed to fabricate investigate pumping capability non-mechanical micropump under effect different porous materials. The self-p...

Abstract Many engineering structures, especially defense applications, need to be reinforced against blast loads due a nearby explosion. Today, much more attention needs given this issue because of increased exposure explosions, and natural disasters. Different solutions have been used in the literature mitigate blast-loading effects. One these sandwich panels, are good candidate for applicatio...

A graph Gs = (V,Es) is a sandwich for a pair of graph Gt = (V,Et) and G = (V,E) if Et ⊆ Es ⊆ E. Any poset, or partially ordered set, admits a unique graph representation which is directed and transitive. In this paper we introduce the notion of sandwich poset problems inspired by former sandwich problems on comparability graphs. In particular, we are interested in seriesparallel and interval po...

Purpose. The main purpose of this work is to substantiate the design features sandwich panels for manufacture container walls size 1SS. Methodology. To ensure strength walls, it proposed use as their components. This involves a panel from two metal sheets, between which material with energy-absorbing properties placed. solution helps improve by reducing its load. determine thickness sheet, corr...

Abstract Applications of sandwich composites are increasing as they continue to develop. The reason for the growth in development and rising demand numerous industries is due its ability achieve high stiffness strength, while simultaneously being lightweight comparison traditional materials. 3D printed plastic hollow core were focused on this study where a bioplastic, Polylactic Acid (PLA), was...

the aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. two types of sandwich composites with e-glass/kevlar/polyester resin facings and end-grain balsa wood as core have been produced by vacuum infusion processing (vip) and hand-lay up (hl) method. compression tests on...
