Six polyphenolic acid esters were synthesized and their antioxidative properties were evaluated in three model systems [2,2'-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay, 2,2'-azobis(2-amidinopropane)dihydrochloride (AAPH)-induced lipid peroxidation system, and the dye-bleaching assay of peroxynitrite radical]. Among these compounds, we(More)
Six novel selenium-containing polyphenolic acid esters were synthesized and evaluated as antioxidants and 5-lipoxygenase inhibitors. Synthesis of the title compounds involved the Mitsunobu reaction of polyphenolic acids with 2-phenylselenoethanol. Compounds and were found to be very effective antioxidants and 5-lipoxygenase inhibitors with activity(More)
Recently, because the rapid development of mobile devices, augmented reality has extended from personal computers to mobile devices. The highly interactive nature of augmented reality with its user has given rise to various augmented reality applications for mobile devices, ranging from mere interaction to marketing, games, navigation, and so on. As such,(More)
Cognitive radio networks (CRNs) have become a popular research topic in recent years. Most existing CRN routing schemes focus on building a route that optimizes a single aspect of a network's performance, such as minimizing interference for primary users, or reducing the propagation delay or hop count. They do not consider the overall transmission(More)
