Mutations play a role in forming fibrils by accelerating the fibril formation process. In this paper we want to extract diseases that caused by those mutations as a result of the impact of the mutations on structural and functional properties of the aggregated protein. We propose a text mining system, to automatically extract mutations, diseases and relations between mutations and diseases. We presented an algorithm based on finite state to cluster mutations found in the same sentence as a sentence could contain different mutation cause different diseases. Also, we presented a co reference algorithm that enables cross-link sentences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloid" title="amyloid">amyloid</a>, <a href="https://publications.waset.org/abstracts/search?q=amyloidosis" title=" amyloidosis"> amyloidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=co%20reference" title=" co reference"> co reference</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20mining" title=" text mining"> text mining</a> </p> <a href="https://publications.waset.org/abstracts/24232/text-mining-techniques-for-prioritizing-pathogenic-mutations-in-protein-families-known-to-misfold-or-aggregate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24232.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">524</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">59</span> Methane Production from Biomedical Waste (Blood)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20M.%20Kabbashi">Fatima M.

Biogas is produced by the bacterial anaerobic digestion of biomaterial (blood). During digestion process bacterial feeding result in breaking down chemical bonds of the biomaterial and changing its features, by the end of the digestion (biogas production) the remains become manure as known. That has led to the economic and eco-friendly disposal of hazard biomedical waste (blood). The samples (Whole blood, Red blood cells 'RBCs', Blood platelet and Fresh Frozen Plasma ‘FFP’) are collected and measured in terms of carbon to nitrogen C/N ratio and total solid, then filled in connected flasks (three flasks) using water displacement method. The results of trails showed that the platelet and FFP failed to produce flammable gas, but via a gas analyzer, it showed the presence of the following gases: CO, HC, CO₂, and NOX. Otherwise, the blood and RBCs produced flammable gases: Methane-nitrous CH₃NO (99.45%), which has a blue color flame and carbon dioxide CO₂ (0.55%), which has red/yellow color flame. Methane-nitrous is sometimes used as fuel for rockets, some aircraft and racing cars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title="renewable energy">renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20waste" title=" biomedical waste"> biomedical waste</a>, <a href="https://publications.waset.org/abstracts/search?q=blood" title=" blood"> blood</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-friendly%20disposal" title=" eco-friendly disposal"> eco-friendly disposal</a> </p> <a href="https://publications.waset.org/abstracts/84424/methane-production-from-biomedical-waste-blood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84424.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">301</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">58</span> Extensions to Chen's Minimizing Equal Mass Paralellogram Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Manur">Abdalla Manur</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Offin"> Daniel Offin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Arsie"> Alessandro Arsie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the extension of the minimizing equal mass parallelogram solutions which was derived by Chen in 2001.

Understanding at the molecular level the mechanisms that govern DNA replication in proliferating cells is fundamental to understand disease connected to genomic instabilities, as a genetic disease and cancer. A key step for DNA replication to take place, is unwinding the DNA double helix and this carried out by proteins called helicases. The archaeal MCM (minichromosome maintenance) complex from Methanothermobacter thermautotrophicus have being studied using Atomic Force Microscopy (AFM), imaging in air and liquid (Physiological environment). The accurate analysis of AFM topographic images allowed to understand the static conformations as well the interaction dynamic of MCM and DNA double helix in the present of ATP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=protein-DNA%20interaction" title=" protein-DNA interaction"> protein-DNA interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=MCM%20%28mini%20chromosome%20manteinance%29%20complex" title=" MCM (mini chromosome manteinance) complex"> MCM (mini chromosome manteinance) complex</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy%20%28AFM%29" title=" atomic force microscopy (AFM)"> atomic force microscopy (AFM)</a> </p> <a href="https://publications.waset.org/abstracts/65589/atomic-force-microscopy-studies-of-dna-binding-properties-of-the-archaeal-mini-chromosome-maintenance-complex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65589.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">308</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">51</span> Exploring Distinct Materials for Hydrogen Storage: A Density Functional Theory Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Ahmad%20Obeidat">Abdalla Ahmad Obeidat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developing efficient hydrogen storage materials is critical to advancing clean energy technologies, particularly for applications in fuel cells and renewable energy systems.

Therefore three commercial breeds (Hypeco, Avian, and Shaver) were evaluated in two regions. The data were obtained from weekly records of three parental flocks for each breed at Ghout El-sultan and Tawargha region. Feed Hen Housed (FHH), Hen Housed Egg Production (HHEP) Mortility % were the studied traits. Statistical model include location, year, month, age and breed. Hypeco produced more HHEP 68.6 with Less FHH 22.9 kg but with higher mortility 8.5 % than Avian and shaver breeds. The breeds exhibited different responses to the different months in Libya. In conclusion, the differences, which exhibited between the breeds in traits studied, indicate that genotype x environment must be considered when select breed to perform under Libyan conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypeco%20avian%20shaver" title="hypeco avian shaver">hypeco avian shaver</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20hen%20housed" title=" feed hen housed"> feed hen housed</a>, <a href="https://publications.waset.org/abstracts/search?q=hen%20housed%20egg%20production" title=" hen housed egg production"> hen housed egg production</a>, <a href="https://publications.waset.org/abstracts/search?q=mortility" title=" mortility"> mortility</a>, <a href="https://publications.waset.org/abstracts/search?q=Libya" title=" Libya"> Libya</a> </p> <a href="https://publications.waset.org/abstracts/35640/evaluation-of-broiler-parent-breeds-under-libyan-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35640.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">289</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">48</span> Developing University EFL Students’ Communicative Competence by Using Communicative Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mutwakel%20Abdalla%20Ali%20Garalzain">Mutwakel Abdalla Ali Garalzain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to develop university EFL students’ communicative competence. The descriptive, analytical method was used in this study. To collect the data, the researcher designed two questionnaires, one for university EFL students and the other for English language teachers. The respondents of the study were eighty-eight; 76 university EFL students, and 12 English language teachers. The data obtained were analyzed by using statistical package for social science (SPSS). The findings of the study have revealed that most of the university EFL students are unable to express their ideas properly, although they have an abundance of vocabulary. The findings of the study have also shown that most of the university EFL students have positive attitudes towards communicative competence. The results of the study also identified the best strategies that can be used to enhance university EFL students’ communicative competence in English language teaching. The study recommends that English language textbooks should be compatible with the requirements of the student-centered approach. It also recommends that English language teachers should adopt the communicative approach’s strategies in the EFL classroom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=applied%20linguistics" title="applied linguistics">applied linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=communicative%20competence" title=" communicative competence "> communicative competence </a>, <a href="https://publications.waset.org/abstracts/search?q=English%20language%20teaching" title=" English language teaching"> English language teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20EFL%20students" title=" university EFL students"> university EFL students</a> </p> <a href="https://publications.waset.org/abstracts/116051/developing-university-efl-students-communicative-competence-by-using-communicative-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116051.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">198</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">47</span> Assessment the Capacity of Retention of a Natural Material for the Protection of Ground Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hakim%20Aguedal">Hakim Aguedal</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Iddou"> Abdelkader Iddou</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Aziz"> Abdalla Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhadi%20Bentouami"> Abdelhadi Bentouami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Bensalah"> Ferhat Bensalah</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Bensadek"> Salah Bensadek </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The major environmental risk of soil pollution is the contamination of groundwater by infiltration of organic and inorganic pollutants that can cause a serious pollution. To prevent the migration of this pollution through this structure, many studies propose the installation of layers, which play a role of a barrier that inhibiting the contamination of groundwater by limiting or slowing the flow of rainwater carrying pollution through the layers of soil. However, it is practically impossible to build a barrier layer that let through only water, but it is possible to design a structure with low permeability, which reduces the infiltration of dangerous pollutant. In an environmental context of groundwater protection, the main objective of this study was to investigate the environmental and appropriate suitability method to preserve groundwater, by establishment of a permeable reactive barrier (PRB) intermediate in soil. Followed the influence of several parameters allow us to find the most effective materials and the most appropriate way to incorporate this barrier in the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ground%20water" title="Ground water">Ground water</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=permeable%20reactive%20Barrier" title=" permeable reactive Barrier"> permeable reactive Barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20pollution." title=" soil pollution."> soil pollution.</a> </p> <a href="https://publications.waset.org/abstracts/22346/assessment-the-capacity-of-retention-of-a-natural-material-for-the-protection-of-ground-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22346.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">556</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">46</span> Evaluation of Groundwater Suitability for Irrigation Purposes: A Case Study for an Arid Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20M.%20Bob">Mustafa M.

The United States Department of Agriculture (USDA) classification of irrigation water that is based on Sodium hazard (SAR) and salinity hazard was used for suitability assessment. In addition, the residual sodium carbonate (RSC) was calculated for all samples and also used for irrigation suitability assessment. Results showed that all groundwater samples are in the acceptable quality range for irrigation based on RSC values. When SAR and salinity hazard were assessed, results showed that while all groundwater samples (except one) fell in the acceptable range of SAR, they were either in the high or very high salinity zone which indicates that care should be taken regarding the type of soil and crops in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irrigation%20suitability" title="irrigation suitability">irrigation suitability</a>, <a href="https://publications.waset.org/abstracts/search?q=TDS" title=" TDS"> TDS</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=SAR" title=" SAR"> SAR</a> </p> <a href="https://publications.waset.org/abstracts/18646/evaluation-of-groundwater-suitability-for-irrigation-purposes-a-case-study-for-an-arid-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18646.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">372</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">45</span> Gesture in the Arabic and Malay Languages a Comparative Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Sara%20binti%20Hj%20Ahmad">Siti Sara binti Hj Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Adil%20Elshiekh%20Abdalla"> Adil Elshiekh Abdalla </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Arabic and Malay languages belong to different language’s families; while the Arabic language descends from the Semitic language, Malay belongs to the Austronesian (Malayo-Polynesian) family. Hence, the grammatical systems of the two languages differ from each other. Arabic, being a language found in the heart of the dessert, and Malay is the language found in the heart of thick equatorial forests, is another source of vital cultural differences. Consequently, it is expected that this situation will create differences in the ways of how speakers of the two languages perceive the world around them, convey and understand their messages. On the other hand, as the majority of the speakers of Malay language are Muslims, Arabic language found its way in this region; currently, Arabic is widely taught in school, some terms of it found their way in the Malay language. Accordingly, the Arabic language and culture have widely penetrated into the Malay language. This study is proposed with the aim to find out the differences and similarities between the two languages, in the term of the nonverbal communication. The result of this study will be of high significance, as it will help in enhancing the mutual understanding between the speakers of these languages. The comparative analysis approach will be utilized in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gesture" title="gesture">gesture</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20language" title=" Arabic language"> Arabic language</a>, <a href="https://publications.waset.org/abstracts/search?q=Malay%20language" title=" Malay language"> Malay language</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20analysis" title=" comparative analysis "> comparative analysis </a> </p> <a href="https://publications.waset.org/abstracts/26388/gesture-in-the-arabic-and-malay-languages-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26388.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">567</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">44</span> The Effect of Artificial Intelligence on Autism Attitudes and Laws</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Noshi%20Esraeil%20Abdalla">Nermin Noshi Esraeil Abdalla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inclusive schooling offerings for college kids with Autism stays in its early developmental levels in Thailand. despite many greater youngsters with autism are attending schools since the Thai authorities brought the training Provision for human beings with Disabilities Act in 2008, the services students with autism and their families obtain are typically missing.

The energy band gaps of the amorphous Mn-doped GeTe thin films with different thicknesses were calculated. The obtained results demonstrated that the energy band gap values of the amorphous films are quite different and they are dependent on the films thicknesses. The extinction coefficients of amorphous Mn-doped GeTe thin films as function of wavelength for different thicknesses were measured. The results showed that the extinction coefficients of all films are varying inversely with their optical transmission. Moreover, the results emphasis that, not only the microstructure, electrical and magnetic properties of Mn doped GeTe thin films vary with the films thicknesses but also the optical properties differ with the film thickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20magnetic%20materials" title="phase change magnetic materials">phase change magnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=transmittance" title=" transmittance"> transmittance</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbance" title=" absorbance"> absorbance</a>, <a href="https://publications.waset.org/abstracts/search?q=extinction%20coefficients" title=" extinction coefficients"> extinction coefficients</a> </p> <a href="https://publications.waset.org/abstracts/48213/the-effect-of-the-deposition-parameters-on-the-microstructural-and-optical-properties-of-mn-doped-gete-chalcogenide-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48213.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">404</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">40</span> The Architecture, Engineering and Construction(AEC)New Paradigm Shift: Building Information Modelling Trend in the United Arab Emirates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salem%20B.%20Abdalla">Salem B.

Two sets of surveys were mailed to the AEC industry and the corresponding academic sector within the UAE to collect up-to-date data on BIM awareness and utilization. The surveys showed startling results concerning the academic sector in the UAE where almost 70% of respondents were not aware of the BIM mandate. Among the rest, even when aware, the majority of mechanical and electrical engineering schools felt that BIM is not pertinent to their discipline. Therefore, the response to offering BIM in their curriculum was substantially low (35%). On the other hand, the industrial survey identified a large majority (76.5%) of the AEC industry in the UAE are using BIM. The results clearly indicate that the academia should include BIM in their curriculum to produce qualified graduates to support the market. However, the academia is also faced with several obstacles to implement BIM in their curriculum, where the main pretext is that there is “no room for new courses in existing curriculum”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling" title="building information modeling">building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20adoption" title=" BIM adoption"> BIM adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE%20BIM%20industry%20survey" title=" UAE BIM industry survey"> UAE BIM industry survey</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE%20BIM%20academia%20survey" title=" UAE BIM academia survey"> UAE BIM academia survey</a>, <a href="https://publications.waset.org/abstracts/search?q=Dubai%20BIM%20mandate" title=" Dubai BIM mandate"> Dubai BIM mandate</a>, <a href="https://publications.waset.org/abstracts/search?q=UK%20BIM%20mandate" title=" UK BIM mandate"> UK BIM mandate</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20education" title=" BIM education"> BIM education</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture%20education" title=" architecture education"> architecture education</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20schools" title=" engineering schools"> engineering schools</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20implementation" title=" BIM implementation"> BIM implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20curriculum" title=" BIM curriculum"> BIM curriculum</a> </p> <a href="https://publications.waset.org/abstracts/38182/the-architecture-engineering-and-constructionaecnew-paradigm-shift-building-information-modelling-trend-in-the-united-arab-emirates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38182.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">415</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">39</span> Banking and Accounting Analysis Researches Effect on Environment and Income</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerges%20Samaan%20Henin%20Abdalla">Gerges Samaan Henin Abdalla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New methods of providing banking services to the customer have been introduced, such as online banking. Banks have begun to consider electronic banking (e-banking) as a way to replace some traditional branch functions by using the Internet as a new distribution channel. Some consumers have at least one account at multiple banks and access these accounts through online banking. To check their current net worth, clients need to log into each of their accounts, get detailed information, and work toward consolidation. Not only is it time consuming, but it is also a repeatable activity with a certain frequency. To solve this problem, the concept of account aggregation was added as a solution. Account consolidation in e-banking as a form of electronic banking appears to build a stronger relationship with customers. An account linking service is generally referred to as a service that allows customers to manage their bank accounts held at different institutions via a common online banking platform that places a high priority on security and data protection. The article provides an overview of the account aggregation approach in e-banking as a new service in the area of e-banking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibility" title="compatibility">compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=complexity" title=" complexity"> complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20banking" title=" mobile banking"> mobile banking</a>, <a href="https://publications.waset.org/abstracts/search?q=observation" title=" observation"> observation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20banking%20technology" title=" risk banking technology"> risk banking technology</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet%20banks" title=" Internet banks"> Internet banks</a>, <a href="https://publications.waset.org/abstracts/search?q=modernization%20of%20banks" title=" modernization of banks"> modernization of banks</a>, <a href="https://publications.waset.org/abstracts/search?q=banks" title=" banks"> banks</a>, <a href="https://publications.waset.org/abstracts/search?q=account%20aggregation" title=" account aggregation"> account aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=enterprise%20development" title=" enterprise development"> enterprise development</a> </p> <a href="https://publications.waset.org/abstracts/184411/banking-and-accounting-analysis-researches-effect-on-environment-and-income" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184411.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">57</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">38</span> New Isolate of Cucumber Mosaic Virus Infecting Banana </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelsabour%20G.%20A.%20Khaled">Abdelsabour G.

The causal agent was identified as Cucumber mosaic virus (CMV) on the basis of symptoms, transmission, serology, transmission electron microscopy and reverse transcription polymerase chain reaction (RT-PCR). Coat protein (CP) gene was amplified using gene specific primers for coat protein (CP), followed by cloning into desired cloning vector for sequencing. In this study the CMV was transmitted into propagation host either by aphid or mechanically. The transmission was confirmed through Direct Antigen Coating Enzyme Linked Immuno Sorbent Assay (DAC-ELISA). Analysis of the 120 deduced amino acid sequence of the coat protein gene revealed that the EG-A strain of CMV shared from 97.50 to 98.33% with those strains belonging to subgroup IA. The cluster analysis grouped the Egyptian isolate with strains Fny and Ri8 belonging sub-group IA. It appears that there occurs a high incidence of CMV infecting banana belonging to IA subgroup in most parts of Egypt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=banana" title="banana">banana</a>, <a href="https://publications.waset.org/abstracts/search?q=CMV" title=" CMV"> CMV</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=CP%20gene" title=" CP gene"> CP gene</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a> </p> <a href="https://publications.waset.org/abstracts/40303/new-isolate-of-cucumber-mosaic-virus-infecting-banana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40303.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">341</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">37</span> Investigations of Inclusion Complexes of Imazapyr with 2-Hydroxypropyl(β/γ) Cyclodextrin Experimental and Molecular Modeling Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20A.%20Elbashir">Abdalla A.

In this work, fluorescence spectroscopy, electrospray-ionization mass spectrometry (ESI-MS), and HNMR were used to investigate and characterize the inclusion complexes of IMA with the cyclodextrins in solutions. The solid-state complexes were obtained by freeze-drying and were characterized by Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (PXRD). The most predominant complexes of IMA with both hosts are the 1:1 guest: host complexes. The association constants of IMA-HP β-CD and IMA-HP γ -CD were 115 and 215 L mol⁻¹, respectively. Molecular dynamic (MD) simulations were used to monitor the mode of inclusion and also to investigate the stability of these complexes in aqueous media at atomistic levels. The results obtained have indicated that these inclusion complexes are highly stable in aqueous media, thereby corroborating the experimental results. Additionally, it has been demonstrated that in addition to hydrophobic interactions and van der Waals interactions the presence of hydrogen bonding interactions of the type H---O and CH---O between the guest and the host have enhanced the stability of these complexes remarkably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=imazapyr" title="imazapyr">imazapyr</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion%20complex" title=" inclusion complex"> inclusion complex</a>, <a href="https://publications.waset.org/abstracts/search?q=herbicides" title=" herbicides"> herbicides</a>, <a href="https://publications.waset.org/abstracts/search?q=2-hydroxypropyl-%CE%B2%2F%CE%B3-cyclodextrin" title=" 2-hydroxypropyl-β/γ-cyclodextrin"> 2-hydroxypropyl-β/γ-cyclodextrin</a> </p> <a href="https://publications.waset.org/abstracts/86839/investigations-of-inclusion-complexes-of-imazapyr-with-2-hydroxypropylvgh-cyclodextrin-experimental-and-molecular-modeling-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86839.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">171</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">36</span> The Effect of Extremely Low Frequency Magnetic Field on Rats Brain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Abdalla">Omar Abdalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelfatah%20Ahmed"> Abdelfatah Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mustafa"> Ahmed Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelazem%20Eldouma"> Abdelazem Eldouma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is evaluating the effect of extremely low frequency magnetic field on Waster rats brain.

We found the time average before exposure for the all groups was G2=330 s, G3=172 s, G4=500 s and G5=174 s, respectively. We exposed all groups to ELF-MF and measured the time and we found: G2=465 s, G3=388 s, G4=501 s, and G5=442 s. It was observed that the time average increased directly with field strength. Histological samples of frontal lop of brain for all groups were taken and we found lesion, atrophy, empty vacuoles and disorder choroid plexus at frontal lope of brain.

A single web service with limited functionality is inadequate to execute a specific task with series of action. So, it is very much required to combine multiple web services with different functionalities to reach the target. Also, it will become more and more challenging, when these services are from different providers with identical functionalities and varying QoS, so while composing the web services, the overall QoS is considered to be the major factor. Also, it is not true that the expected QoS is always attained when the task is completed. A single web service in the composed chain may affect the overall performance of the task. So care should be taken in different aspects such as functionality of the service, while composition. Dynamic and automatic service composition is one of the main option available. But to achieve the actual functionality of the task, quality of the individual web services are also important. Normally the QoS of the individual service can be evaluated by using the non-functional parameters such as response time, throughput, reliability, availability, etc. At the same time, the QoS is not needed to be at the same level for all the composed services. So this paper proposes a framework that allows composing the services in terms of QoS by setting the appropriate weight to the non-functional parameters of each individual web service involved in the task. Experimental results show that the importance given to the non-functional parameter while composition will definitely improve the performance of the web services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composition" title="composition">composition</a>, <a href="https://publications.waset.org/abstracts/search?q=non-functional%20parameters" title=" non-functional parameters"> non-functional parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20service" title=" quality of service"> quality of service</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service" title=" web service"> web service</a> </p> <a href="https://publications.waset.org/abstracts/57664/functionality-based-composition-of-web-services-to-attain-maximum-quality-of-service" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57664.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">332</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">34</span> Design of a Real Time Heart Sounds Recognition System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omer%20Abdalla%20Ishag">Omer Abdalla Ishag</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdi%20Baker%20Amien"> Magdi Baker Amien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Physicians used the stethoscope for listening patient heart sounds in order to make a diagnosis. However, the determination of heart conditions by acoustic stethoscope is a difficult task so it requires special training of medical staff. This study developed an accurate model for analyzing the phonocardiograph signal based on PC and DSP processor. The system has been realized into two phases; offline and real time phase. In offline phase, 30 cases of heart sounds files were collected from medical students and doctor's world website. For experimental phase (real time), an electronic stethoscope has been designed, implemented and recorded signals from 30 volunteers, 17 were normal cases and 13 were various pathologies cases, these acquired 30 signals were preprocessed using an adaptive filter to remove lung sounds. The background noise has been removed from both offline and real data, using wavelet transform, then graphical and statistics features vector elements were extracted, finally a look-up table was used for classification heart sounds cases. The obtained results of the implemented system showed accuracy of 90%, 80% and sensitivity of 87.5%, 82.4% for offline data, and real data respectively.

In the present study, the effects of lipoic acid were investigated on the key mediators of Rheumatoid arthritis, namely, CD4+CD25+ T cell subsets, GITR expressing cells, CD4+CD25+Foxp3+ regulatory T (Treg) cells, T-helper-17 (Th17) cells and pro-inflammatory cytokines Interleukin-1β (IL-1β), Interleukin-6 (IL-6) and Tumor Necrosis Factor- α (TNF-α)] through flow-cytometry and qPCR analyses. Lipoic acid-treated mice showed a significant decrease in Rheumatoid arthritis, the frequency of GITR-expressing cells, and Th1 cytokines (IL-17A, TNF-αand Interferon- γ (IFN-γ) compared with positive and negative controlled mice. Lipoic acid treatment also downregulated the mRNA expression of the inflammatory mediators compared with the Rheumatoid arthritis mouse model and untreated mice. The number of Tregs was also found to be significantly upregulated in lipoic acid-treated mice. Our results were confirmed by the histopathological examination. This study showed the beneficial role of lipoic acid in promoting a well-balanced tool for the therapy of Rheumatoid arthritis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipoic%20acid" title="lipoic acid">lipoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20markers" title=" inflammatory markers"> inflammatory markers</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title=" rheumatoid arthritis"> rheumatoid arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=qPCR" title=" qPCR"> qPCR</a> </p> <a href="https://publications.waset.org/abstracts/158873/study-the-effect-of-lipoid-acid-as-a-protective-against-rheumatoid-arthritis-through-diminishing-pro-inflammatory-markers-and-chemokine-expression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158873.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">100</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">32</span> A Comprehensive Review of Foam Assisted Water Alternating Gas (FAWAG) Technique: Foam Applications and Mechanisms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Shabib-Asl">A.

This is accomplished by the study and application of various methods. As for recent cases, the study of fluid mobility control and sweep efficiency in gas injection process as well as water alternating gas (WAG) method have demonstrated positive results on oil recovery and thus gained wide interest in petroleum industry. WAG injection application results in an increased oil recovery. Its mechanism consists in reduction of gas oil ratio (GOR). However, there are some problems associated with this which includes poor volumetric sweep efficiency due to its low density and high mobility when compared with oil. This has led to the introduction of foam assisted water alternating gas (FAWAG) technique, which in contrast with WAG injection, acts in improving the sweep efficiency and reducing the gas oil ration therefore maximizing the production rate from the producer wells. This paper presents a comprehensive review of FAWAG process from perspective of Snorre field experience. In addition, some comparative results between FAWAG and the other EOR methods are presented including their setbacks. The main aim is to provide a solid background for future laboratory research and successful field application-extend. <p class="card-text"><strong>Keywords:</strong> <a
