The accumulation of massive waste has impacted human health and the city's appearance. As a result, there was need to reduce by using by-products from industrial replace cement, such as limestone, fly ash, silica fume, steel slag, other minerals known supplementary cementitious materials are produced environmentally sustainably. This paper's purpose is design green mortar with highest possible ...

Material jetting (MJT) products have a high subjective appearance quality in additive manufacturing (AM). MJT objects are typically manufactured from multiple layers of semi-transparent photo resins to achieve the desired appearance. This study explores optical properties photopolymer plates monolayer and bilayer combinations. The role white substrate as background plate configurations is discu...

Synthetic polymers belonging to the aliphatic polyester group have become highly promising biomaterials for reconstructive medicine. The purpose of the present work is a biological evaluation of lactide-glycolide co-polymer (PLGA) and its composites with carbon fibers (PLGA+CF) or hydroxyapatite (PLGA+HA). The cytotoxicity of the evaluated materials towards hFOB 1.19 human osteoblast-like cells...

This study aims at empirically measuring a universal criterion for materials evaluation, i.e., learning opportunities, in a locally- and a globally-designed materials. Adopting the conceptual framework of sociocultural theory and its conceptualization of learning as participation (Donato, 2000), the researchers utilized the methodological power of conversation analysis to examine how opportunit...

Ultrasonic testing using couplants is most popular technique for non destructive testing of solid materials. In the most non – destructive evaluation tasks such as investigation of materials whose properties may be changed by liquid contact this technique can not be used. Use of contact technique can be restricted for complex geometry structures. Also, liquid couplants cannot be used when mater...

This study attempted to evaluate and compare language learning apps and the related traditional books on the same subject. The apps included Murphy’s English Grammar and Cambridge Discovery Readers and the traditional materials were English Grammar in Use and Developing Reading Skills. The study, thus, aimed to do a comparative analysis between traditional ELT materials and the digital versions...
