Chemical asphaltene dispersants are hazardous to the marine environment, so Ionic liquids (ILs) as asphaltene dispersants are a critical area of study. In this work, different aryl imidazolium ionic liquids were synthesized with high yield and elucidated via tools of analysis (Elemental analysis, FT-IR, and 1H-NMR). Thermogravimetric analysis confirmed that the prepared ILs posses high thermal stability. The critical micelle concentration (CMC), surface tension, and emulsification index were investigated. Evaluation of synthesized ILs as asphaltene dispersants were assessed at various concentrations, and data reveals high dispersion efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title="ionic liquids">ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20spill" title=" oil spill"> oil spill</a>, <a href="https://publications.waset.org/abstracts/search?q=asphaltene%20dispersants" title=" asphaltene dispersants"> asphaltene dispersants</a>, <a href="https://publications.waset.org/abstracts/search?q=CMC" title=" CMC"> CMC</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a> </p> <a href="https://publications.waset.org/abstracts/141084/effect-of-aryl-imidazolium-ionic-liquids-as-asphaltene-dispersants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141084.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">194</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> Effect of Asymmetric Amphiphilic Dicationic Ionic Liquids as Oil Spill Dispersants in Red Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raghda%20El-Nagara">Raghda El-Nagara</a>, <a href="https://publications.waset.org/abstracts/search?q=Maher%20I.%20Nessim"> Maher I.

They were elucidated via conventional tools of analysis (elemental analysis, FT-IR, and 1H-NMR). The thermogravimetric analysis confirmed that the three ADILs possessed high thermal stability (up to 500ᵒC). Their critical micelle concentration (CMC) was investigated and exhibited values of 5.5-1*10⁻³ Mol./L. They were evaluated as oil spill dispersants were at different temperatures (10, 30 & 50ᵒC) with different concentrations (750, 1500, 2000, 3000 ppm). Data reveals that the efficiency is ranked as follows: IL₂ > IL₁ > IL₃, which showed high dispersion efficiency reached to 63% with the concentration of 1500 ppm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title="ionic liquids">ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=amphiphilic" title=" amphiphilic"> amphiphilic</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20spill%20dispersants" title=" oil spill dispersants"> oil spill dispersants</a>, <a href="https://publications.waset.org/abstracts/search?q=dicationic" title=" dicationic"> dicationic</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency%20test" title=" efficiency test"> efficiency test</a> </p> <a href="https://publications.waset.org/abstracts/135621/effect-of-asymmetric-amphiphilic-dicationic-ionic-liquids-as-oil-spill-dispersants-in-red-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135621.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">151</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> A Business Model Design Process for Social Enterprises: The Critical Role of the Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadia%20Abdel%20Aziz">Hadia Abdel Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Raghda%20El%20Ebrashi"> Raghda El Ebrashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Business models are shaped by their design space or the environment they are designed to be implemented in. The rapidly changing economic, technological, political, regulatory and market external environment severely affects business logic. This is particularly true for social enterprises whose core mission is to transform their environments, and thus, their whole business logic revolves around the interchange between the enterprise and the environment. The context in which social business operates imposes different business design constraints while at the same time, open up new design opportunities. It is also affected to a great extent by the impact that successful enterprises generate; a continuous loop of interaction that needs to be managed through a dynamic capability in order to generate a lasting powerful impact. This conceptual research synthesizes and analyzes literature on social enterprise, social enterprise business models, business model innovation, business model design, and the open system view theory to propose a new business model design process for social enterprises that takes into account the critical role of environmental factors. This process would help the social enterprise develop a dynamic capability that ensures the alignment of its business model to its environmental context, thus, maximizing its probability of success. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20enterprise" title="social enterprise">social enterprise</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model" title=" business model"> business model</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model%20design" title=" business model design"> business model design</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model%20environment" title=" business model environment"> business model environment</a> </p> <a href="https://publications.waset.org/abstracts/48331/a-business-model-design-process-for-social-enterprises-the-critical-role-of-the-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48331.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">371</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> Obstetric Violence Consequences And Coping Strategies: Insights Through The Voices Of Arab And Jewish Women In Israel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dganit%20Sharon">Dganit Sharon</a>, <a href="https://publications.waset.org/abstracts/search?q=Raghda%20Alnabilsy"> Raghda Alnabilsy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of this qualitative research was to sound the voices of Jewish and Arab women in Israel who had experienced obstetric violence, to learn the consequences of the violence to them on different levels and over time, and to present their coping strategies from their perspective. Another goal was to expand the research knowledge on an issue that has not been studied among Arab and Jewish women in Israel. The premise of this study is the feminist approach that aims to promote human rights, and to eradicate phenomena related to cultural, structural, gender and patriarchal structures of women, their bodies, and their health. The research was based on the qualitative-constructivist methodology, by means of thematic analysis of 20 in-depth semi-structured interviews. Two main themes emerged from the analysis. First, the physical and emotional consequences of obstetric violence, consequences to spousal relationships, and mistrust of the health system and service providers. Second, women’s coping strategies with obstetric violence that included repression and avoidance as a way of coping with the pain and trauma of the abuse; garnering inner strengths, resilience, knowledge and awareness of the delivery process; recruiting and relying on external help; sharing on social media, and discussions with other women who had similar experiences; or reaching out to therapists / legal aid / public complaints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obstetric%20violence" title="obstetric
