A qualitative exploratory research was conducted to support the conceptual framework followed with a quantitative research in the form of a survey distributed among 411 respondents. It was clear that relative advantage, complexity, compatibility, perceived price level and perceived playfulness have a dominant role in influencing consumers to adopt mobile internet, while observability is correlated to the adoption but when measured with the other factors it lost its value. The perceived price level has a negative relationship with the adoption as well the compatibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20technologies" title=" communication technologies"> communication technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion" title=" diffusion"> diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20adoption" title=" innovation adoption"> innovation adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20market" title=" emerging market"> emerging market</a> </p> <a href="https://publications.waset.org/abstracts/9854/factors-affecting-mobile-internet-adoption-in-an-emerging-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9854.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> A Regulatory Analysis on Legal Problems of BitCoin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fady%20Tawakol">Fady Tawakol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BitCoin is a decentralized cryptocurrency that can be used without the need of traditional central banks to accomplish any e-commerce trade. The use of such currency could facilitate new economic interactions and linkages. However, without effective and efficient regulations, cryptocurrency transactions are mostly used by criminals to commit crimes such as money laundering, theft, and blackmailing. And because law is one step behind technological developments, this paper discusses the importance of regulations and supervision for the BitCoin-system, to provide unified regulatory solutions for our digital future in the Middle East. It will provide a detailed analysis of the legal nature of BitCoin along with, its regulation with respect to criminal and civil law. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BitCoin" title="BitCoin">BitCoin</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20protection" title=" financial protection"> financial protection</a>, <a href="https://publications.waset.org/abstracts/search?q=crypto%20currency" title=" crypto currency"> crypto currency</a>, <a href="https://publications.waset.org/abstracts/search?q=money%20laundering" title=" money laundering"> money laundering</a> </p> <a href="https://publications.waset.org/abstracts/89987/a-regulatory-analysis-on-legal-problems-of-bitcoin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89987.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Scalable Cloud-Based LEO Satellite Constellation Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Sobh">Karim Sobh</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20El-Ayat"> Khaled El-Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Fady%20Morcos"> Fady Morcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Amr%20El-Kadi"> Amr El-Kadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distributed applications deployed on LEO satellites and ground stations require substantial communication between different members in a constellation to overcome the earth coverage barriers imposed by GEOs. Applications running on LEO constellations suffer the earth line-of-sight blockage effect. They need adequate lab testing before launching to space. We propose a scalable cloud-based net-work simulation framework to simulate problems created by the earth line-of-sight blockage. The framework utilized cloud IaaS virtual machines to simulate LEO satellites and ground stations distributed software. A factorial ANOVA statistical analysis is conducted to measure simulator overhead on overall communication performance. The results showed a very low simulator communication overhead. Consequently, the simulation framework is proposed as a candidate for testing LEO constellations with distributed software in the lab before space launch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LEO" title="LEO">LEO</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=constellation" title=" constellation"> constellation</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite" title=" satellite"> satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20simulation" title=" network simulation"> network simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=netfilter" title=" netfilter"> netfilter</a> </p> <a href="https://publications.waset.org/abstracts/23478/scalable-cloud-based-leo-satellite-constellation-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23478.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Activity of Commonly Used Intravenous Nutrient and Bisolvon in Neonatal Intensive Care Units against Biofilm Cells and Their Synergetic Effect with Antibiotics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Fady%20Abozed">Marwa Fady Abozed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hemat%20Abd%20El%20Latif"> Hemat Abd El Latif</a>, <a href="https://publications.waset.org/abstracts/search?q=Fathy%20Serry"> Fathy Serry</a>, <a href="https://publications.waset.org/abstracts/search?q=Lotfi%20El%20Sayed"> Lotfi El Sayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to investigate the efficacy of intravenous nutrient(soluvit, vitalipid, aminoven infant, lipovenos) and bisolvon commonly used in neonatal intensive care units against biofilm cells of staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aerguinosa and klebseilla pneumonia as they are the most commonly isolated organisms and are biofilm producers. Also, the synergetic acticity of soluvit, heparin, bisolvon with antibiotics and its effect on minimum biofilm eradication concentration(MBEC) was tested. Intravenous nutrient and bromohexine are widely used in newborns. Numbers of viable cell count released from biofilm after treatment with intravenous nutrient and bromohexine were counted to compare the efficacy. The percentage of reduction in biofilm regrowth in case of using soluvit was 43-51% and 36-42 % for Gram positive and Gram negative respectively, on adding the vitalipid the percentage was 45-50 %and 37-41% for Gram positive and Gram negative respectively. While, in case of using bisolvon the percentage was 46-52% and 47-48% for Gram positive and Gram negative respectively. Adding lipovenos had a reduction percentage of 48-52% and 48-49% for Gram positive and Gram negative respectively. While, adding aminoven infant the percentage was 10-15% and 9-11% for Gram positive and Gram negative respectively. Adding soluvit, heparin and bisolvon to antibiotics had synergic effect. soluvit with ciprofloxacin has 8-16 times decrease than minimum biofilm eradication concentration (MBEC) for ciprofloxacin alone. While, by adding soluvit to vancomycin the MBEC reduced by 16 times than MBEC of vancomycin alone. In case of combination soluvit with cefotaxime, amikacin and gentamycin the reduction in MBEC was 16, 8 and 6-32 times respectively. The synergetic effect of adding heparin to ciprofloxacin, vancomycin, cefotaxime, amikacin and gentamicin was 2 times reduction with all except in case of gram negative the range of reduction was 0-2 with both gentamycin and ciprofloxacin. Bisolvon exihited synergetic effect with ciprofloxacin, vancomycin, cefotaxime, amikacin and gentamicin by 16, 32, 32, 8, 32-64 and 32 times decrease in MBEC respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm" title="biofilm">biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20intensive%20care%20units" title=" neonatal intensive care units"> neonatal intensive care units</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiofilm%20agents" title=" antibiofilm agents"> antibiofilm agents</a>, <a href="https://publications.waset.org/abstracts/search?q=intravenous%20nutrient" title=" intravenous nutrient"> intravenous nutrient</a> </p> <a href="https://publications.waset.org/abstracts/44503/activity-of-commonly-used-intravenous-nutrient-and-bisolvon-in-neonatal-intensive-care-units-against-biofilm-cells-and-their-synergetic-effect-with-antibiotics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Predictive Modelling of Curcuminoid Bioaccessibility as a Function of Food Formulation and Associated Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20De%20Castro%20Cogle">Kevin De Castro Cogle</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirian%20Kubo"> Mirian Kubo</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Anastasiadi"> Maria Anastasiadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fady%20Mohareb"> Fady Mohareb</a>, <a href="https://publications.waset.org/abstracts/search?q=Claire%20Rossi"> Claire Rossi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The bioaccessibility of bioactive compounds is a critical determinant of the nutritional quality of various food products. Despite its importance, there is a limited number of comprehensive studies aimed at assessing how the composition of a food matrix influences the bioaccessibility of a compound of interest. This knowledge gap has prompted a growing need to investigate the intricate relationship between food matrix formulations and the bioaccessibility of bioactive compounds. One such class of bioactive compounds that has attracted considerable attention is curcuminoids. These naturally occurring phytochemicals, extracted from the roots of Curcuma longa, have gained popularity owing to their purported health benefits and also well known for their poor bioaccessibility Project aim: The primary objective of this research project is to systematically assess the influence of matrix composition on the bioaccessibility of curcuminoids. Additionally, this study aimed to develop a series of predictive models for bioaccessibility, providing valuable insights for optimising the formula for functional foods and provide more descriptive nutritional information to potential consumers. Methods: Food formulations enriched with curcuminoids were subjected to in vitro digestion simulation, and their bioaccessibility was characterized with chromatographic and spectrophotometric techniques. The resulting data served as the foundation for the development of predictive models capable of estimating bioaccessibility based on specific physicochemical properties of the food matrices. Results: One striking finding of this study was the strong correlation observed between the concentration of macronutrients within the food formulations and the bioaccessibility of curcuminoids. In fact, macronutrient content emerged as a very informative explanatory variable of bioaccessibility and was used, alongside other variables, as predictors in a Bayesian hierarchical model that predicted curcuminoid bioaccessibility accurately (optimisation performance of 0.97 R2) for the majority of cross-validated test formulations (LOOCV of 0.92 R2). These preliminary results open the door to further exploration, enabling researchers to investigate a broader spectrum of food matrix types and additional properties that may influence bioaccessibility. Conclusions: This research sheds light on the intricate interplay between food matrix composition and the bioaccessibility of curcuminoids. This study lays a foundation for future investigations, offering a promising avenue for advancing our understanding of bioactive compound bioaccessibility and its implications for the food industry and informed consumer choices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioactive%20bioaccessibility" title="bioactive
