E-Folklore and cyber-communication among Emirati youth
El-Sayed el-Aswad 국립민속박물관 2014 International Journal of Intangible Heritage Vol.9 No.-
The objective of this article is to explain the emergence of anew mediated heritage-social sphere and the articulation ofa contemporary Emirati identity that transforms traditionaloral heritage into an innovative form of electronic folkheritage. The literature addressing changes in folkheritage caused by the flourishing of new media, as wellas off- and on-line social networking in the UAE, is scant. This research seeks to fill that gap by showing howEmirati nationals have succeeded in assimilating outsideinfluences without deserting their heritage, and howglobal and local forms of communication have generatedunique cultural patterns that help Emirati peoplemaintain their identity, authenticity and socialconnectivity in a globally changing world. The studyshows that the Internet provides information zones,enhancing people’s knowledge, and interaction zones,strengthening people’s social relationships. Tounderstand these two domains, this inquiry addressesonline heritage and cyber-communication as used byboth the UAE government (formal network) and ordinaryE-Folklore and cyber-communicationamong Emirati youthpeople (informal network). For the purpose of theorisinge-folklore, this research proposes a paradigm dealingwith the content and form of heritage by bridgingtraditional/oral and technical/textual forms ofcommunication. For Emirati young people, focusing oncontent allows for unusual engagement with the pastthrough technologies that have the potential to shape andinfluence their future heritage. Emirati folk heritage hasundergone a sort of ‘cyber-communication’ or‘internetisation’, which means a process through whichcore elements of folk heritage are mediated by theInternet, reaching diverse audiences and allowing forbroad public participation.

Stress waves transmission from railway track over geogrid reinforced ballast underlain by clay
Fattah, Mohammed Y.,Mahmood, Mahmood R.,Aswad, Mohammed F. Techno-Press 2022 Structural monitoring and maintenance Vol.9 No.1
Extensive laboratory tests were conducted to investigate the effect of load amplitude, geogrid position, and number of geogrid layers, thickness of ballast layer and clay stiffness on behavior of reinforced ballast layer and induced strains in geogrid. A half full-scale railway was constructed for carrying out the tests, the model consists of two rails 800 mm in length with three wooden sleepers (900 mm × 10 mm × 10 mm). The ballast was overlying 500 mm thickness clay in two states, soft and stiff state. Laboratory tests were conducted to investigate the response of the ballast and the clay layers where the ballast was reinforced by a geogrid. Settlement in ballast and clay, soil pressure and pore water pressure induced in the clay were measured in reinforced and unreinforced ballast cases. It was concluded that the effect of frequency on the settlement ratio is almost constant after 500 cycles. This is due to that the total settlement after 500 cycles, almost reached its peak value, which means that the ballast particles become very close to each other, so the frequency is less effective for high contact particles forces. The average maximum vertical stress and pore water pressure increased with frequency.

The use of highly efficient, environment-friendly and economically inexpensive materials for the adsorption removal of contaminants from water has always been considered as emerging task. In this study, we synthesized hybrid tri-metallic nickel cobalt layered double hydroxide (NiCoAl-LDH) porous material for the adsorption removal of Eosin yellow (EY) and Malachite green (MG) from water. The characterization results disclosed that tri-metallic LDH has been synthesized with extraordinary purity, identical morphology and high surface area (134.21 m2·g−1). The NiCoAl-LDH performs the best for adsorption of EY (qe=37.30mg·g−1 at pH=2) and MG (qe=39.61 mg·g−1 at pH=10). The Langmuir and Freundlich isotherm models were applied to explain the adsorption process of dyes on the surface of LDH. The Langmuir model (R2=0.991 and 0.999 for Eosin Y and Malachite G, respectively) was very appropriate to explain the process of adsorption on NiCoAl-LDH as homogeneous (monolayer). The maximum adsorption capacity of EY and MG calculated with Langmuir model was 78.74 and 110.13 mg·g−1 at 30 °C, respectively. Also with 240 minutes contact time 94.8% EY and 89.9% MG was adsorbed by as synthesized NiCoAl-LDH nanosheets. The NiCoAl-LDH nanosheets showed excellent performance of reusability of up to five regeneration cycles. The results showed that the adsorption capacity of NiCoAl-LDH nanosheets after five regeneration cycles, to adsorb EY, decreased only from 40.80 to 36.93 mg·g−1 and that of MG from 79.21 to 75.42 mg·g−1, which is acceptable. The overall results Suggest that the fabricated NiCoAl-LDH is favorable for the purification of dye contaminated water.
