Role Of Iconic Architecture In Sustainable Tourism Development, Basim H. H. Al-Majidi, Ann Samari Ibrahim

Al-Esraa University College Journal for Engineering Sciences

Architecture "is an expression of the way of life and the spirit of the ages and cultures in which I grew up" as the buildings speak for themselves. While tourism is a scenario "to define a city to an unfamiliar audience and acquire an identity for a citizen". Both architecture and tourism have been linked together since time immemorial. Architecture was the main aspect of attracting crowds, while tourism helped architecture survive the test of time as well as money. Both tourism and architecture operate in a symbiotic manner to break the lack of familiarity with any culture and to …

Henry M. Rowan College of Engineering Departmental Research

Few droplet generators manufactured using desktop stereolithography 3D printers have been reported in the literature. Moreover, 3D printed microfluidic chips are typically hydrophobic, limiting their application to water in oil droplets. Herein, we present designs for concentric and planar 3D printed microfluidic devices suitable for making polymeric microparticles using an off-the-shelf commercial stereolithography printer and resin. The devices consist of a microscope slide, binder clips, and printed components. Channels were modified by an ultraviolet grafting of methacrylic acid to the surface of chips, yielding a hydrophilic coating without modification to the bulk polymer. The water contact angle decreased from 97.0° …
