The Olga software was used to estimate the pressure increase in the pipeline due to the injection of the gas. Furthermore, potential flow assurance problems were checked using the same software. It was found that all the produced gas can be safely injected in the pipeline as the resulting pressure increase did not reach its maximum allowable operating pressure (MAOP). Hydrate formation and slug problems were predicted by Olga. It was shown that they can be readily handled using a slug catcher for the first and Mono-ethylene Glycol&nbsp;(MEG) injection for the second.</p> Tawba Fallah Aicha mabrouk Jalel Belghaieb Nejib Hajji Copyright (c) 2019 IJRDO - Journal of Applied Science (ISSN: 2455-6653) http://creativecommons.org/licenses/by-nc-nd/4.0 2019-09-13 2019-09-13 5 9 01 10 Non-volatile Memory Effect in Iron Nanoparticles Dispersed Ferroelectric Liquid Crystal https://ijrdo.org/index.php/as/article/view/3170 <p>The research on new devices dedicated to the information storage represents a field in which the investments and the efforts of both industry and applied sciences are continuously growing in the last decades. This is due to the fact that the development of modern society is strictly connected with the need to increase the amount of information circulating at the global level. All this, increases the demand for increasingly efficient memory systems, both in terms of execution speed and energy consumption. To meet this demand, some frontier research is proposing various alternative solutions to the traditional silicon-based technology. The study proposed in this article is part of the trend of devices based on nanocomposed materials. In particular, a pronounced memory effect has been observed in a commercial ferroelectric liquid crystal doped with iron nanoparticles using a dielectric spectroscopy technique. The experimental data would lead to the hypothesis that this effect is due to a sort of switch between an initial phase, strongly distorted because the presence of the iron nanoparticles, to a restored smectic-C phase which take place by the application of a bias voltage.</p> Lucia Marino Nicola Scaramuzza Salvatore Marino Copyright (c) 2019 IJRDO - Journal of Applied Science (ISSN: 2455-6653) http://creativecommons.org/licenses/by-nc-nd/4.0 2019-10-09 2019-10-09 5 9 11 24
