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">315</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">314</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.

Hence, this study would highlight the surgical outcomes of such surgical approach that will assist orthopedic surgeons to detect which surgical procedure needs to be done as well as to help them regarding their diagnostic workups. Methods: At the Orthopedic Division of King Abdul‑Aziz Medical City in Riyadh and through a cross‑sectional design and convenient sampling techniques, the present study had recruited 20 subjects who fulfill the inclusion and exclusion criteria between 2016 and 2018. Data collection was carried out by a questionnaire designed and revised by an expert panel of health professionals. Results: Twenty patients were reviewed (11M and 9F) with an average age of 40.1 ± 12.2. Only 30% of the patients (5M, 1F) have no comorbidity, but 70% of patients (7M, 8F) were having at least one comorbidity. The most common indications were osteochondritis dissecans (n = 7, 35%), ankle fracture without dislocation (n = 4, 20%), and tibiotalar impingement (n = 3, 15%). Patients recorded pain in all cases (100%). The top four symptoms after pain were instability (30%, n = 6), muscle weakness (15%, n = 3) swelling (15%, n = 3), and stiffness (5%, n = 1). Two‑third of cases reached to their full healthy status and toe‑touch weight‑bearing was seen in two patients (10%). Conclusion: Ankle arthroscopy improved the rehabilitation rates in our tertiary care center. In addition, the surgical outcomes are favorable in our hospital since it has a very short length of stay, unexpended surgery, and fewest physiotherapy sessions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankle" title="ankle">ankle</a>, <a href="https://publications.waset.org/abstracts/search?q=arthroscopy" title=" arthroscopy"> arthroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=indications" title=" indications"> indications</a>, <a href="https://publications.waset.org/abstracts/search?q=patterns" title=" patterns"> patterns</a> </p> <a href="https://publications.waset.org/abstracts/170996/ankle-arthroscopy-indications-patterns-of-admissions-surgical-outcomes-and-associated-complications-among-saudi-patients-at-king-abdul-aziz-medical-city-in-riyadh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170996.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">87</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">309</span> Weighted G2 Multi-Degree Reduction of Bezier Curves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salisu%20ibrahim">Salisu ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Rababah"> Abdalla Rababah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, we use Weighted G2-Multi-degree reduction of Bezier curve of degree n to a Bezier curve of degree m, m < n.

Chronic diseases such as cardiovascular disease and diabetes can lead to mobility disability in particular and disability in general. The ICF is an integrative bio-psycho-social model of functioning and disability and considered by the World Health Organization (WHO) to be a reference for disability classification using its categories and core set to classify disorder’s functional limitations. Specialist programs at Sultan Bin Abdul Aziz Humanitarian City (SBAHC) are providing both inpatient and outpatient services have started to implement the ICF and use it as a problem solving tool in Rehab. Diabetes is leading contributing factor for disability and considered epidemic in several Gulf countries including the Kingdom of Saudi Arabia (KSA), where its prevalence continues to increase dramatically. Metabolic disorders, mainly diabetes are not well covered in Rehab field. The purpose of this study is present to research and clinical rehabilitation field of DREAM and ICF as a framework in clinical and research setting in Rehab service. Also, shed the light on using the ICF as problem solving tool at SBAHC. There are synergies between disability causes and wider public health priorities in relation to both chronic disease and disability prevention. Therefore, there is a need for strong advocacy and understanding of the role of ICF as a reference in Rehab settings in Middle East if we wish to seize the opportunity to reverse current trends of acquired disability in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20classification%20of%20functioning" title="international classification of functioning">international classification of functioning</a>, <a href="https://publications.waset.org/abstracts/search?q=disability%20and%20health%20%28ICF%29" title=" disability and health (ICF)"> disability and health (ICF)</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype" title=" prototype"> prototype</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation%20and%20diabetes" title=" rehabilitation and diabetes"> rehabilitation and diabetes</a> </p> <a href="https://publications.waset.org/abstracts/15044/the-international-classification-of-functioning-disability-and-health-icf-as-a-problem-solving-tool-in-disability-rehabilitation-and-education-alliance-in-metabolic-disorders-dream-at-sultan-bin-abdul-aziz-humanitarian-citya-prototype-for-reh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15044.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">351</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">307</span> Qualitative Risk Assessment of Rift Valley Fever Vaccine Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20E.%20Mansour">Mohammed E.

It enhances mechanical properties, corrosion resistance, and homogeneity of the microstructure. In this study, the effect of ultrasonic treatment and several casting conditions on microstructure, hardness and corrosion behavior of AC4C aluminum alloy was examined. Various ultrasonic treatments of the AC4C alloys were carried out to prepare billets for thixocasting process. Treatment temperatures varied from about 630oC and cooled down to under ultrasonic field. Treatment time was about 90s. A 600-watts ultrasonic system with 19.5 kHz and intensity of 170 W/cm2 was used. Billets were reheated to semisolid state and held for 5 minutes at 582 oC and temperatures (soaking) using high-frequency induction system, then thixocasted using a die casting machine. Microstructures of the thixocast parts were studied using optical and SEM microscopes. On the other hand, two samples were conventionally cast and poured at 634 oC and 750 oC. The microstructure showed a globular none dendritic grains for AC4C with the application of UST at 630-582 oC, Less dendritic grains when the sample was conventionally cast without the application of UST and poured at 624 oC and a fully dendritic microstructure When the sample was cast and poured at 750 oC without UST .The ultrasonic treatment during solidification proved that it has a positive influence on the microstructure as it produced the finest and globular grains thus it is expected to increase the mechanical properties of the alloy. Higher values of corrosion resistance and hardness were recorded for the ultrasound-treated sample in comparison to cast one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20treatment" title="ultrasonic treatment">ultrasonic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloys" title=" aluminum alloys"> aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20behaviour" title=" corrosion behaviour"> corrosion behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behaviour" title=" mechanical behaviour"> mechanical behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/51190/effect-of-high-intensity-ultrasonic-treatment-on-the-micro-structure-corrosion-and-mechanical-behavior-of-ac4c-aluminium-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51190.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">353</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">305</span> Anatomy Study of Seeds of Calligonium comosum in Vitro</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abobkar%20Saad">Abobkar Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Qasmia%20Abdalla"> Qasmia Abdalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Emhemed"> Fatma Emhemed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eighty-four of Calligonum comosum were cultured on Murashige and Skoog medium on every combination supplemented with different concentrations of IAA, BA, Zeatin, and GA3.

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">297</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">296</span> Modelling Asymmetric Magnetic Recording Heads with an Underlayer Using Superposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Edress%20Mohamed">Ammar Edress Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Aziz"> Mustafa Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Wright"> David Wright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses and calculates the head fields of asymmetrical 2D magnetic recording heads when the soft-underlayer is present using the appropriate Green's function to derive the surface potential/field by utilising the surface potential for asymmetrical head without underlayer.

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">294</span> Impact of Implementation of Right to Education in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rukhsar%20Ahmed">Rukhsar Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawed%20Aziz%20Masudi"> Jawed Aziz Masudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, an attempt has been made about the right to an education in Pakistan.

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">292</span> Performance Analysis of SAC-OCDMA System using Different Detectors </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somaya%20A.%20Abd%20El%20Mottaleb">Somaya A.

The optical properties of the Ge<sub>1-x</sub>Mn<sub>x</sub>Te thin films with different thicknesses are determined by analyzing the transmittance and reflectance data. 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">287</span> The Impact of Varying the Detector and Modulation Types on Inter Satellite Link (ISL) Realizing the Allowable High Data Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Zaki%20M.">Asmaa Zaki M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abd%20El%20Aziz"> Ahmed Abd El Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20A.%20Fayed"> Heba A.
