“Radès la Goulette” bridge project using the technique of prefabricated vertical drains (PVD) associated with step by step construction of preloading embankments with averaged height of about 6 m. These embankments are founded on a highly compressible layer of Tunis soft soil. The construction steps included extensive soil instrumentation such as piezometers and settlement plates for monitoring the dissipation of excess pore water pressures and settlement during the consolidation of Tunis soft soil. An axisymmetric numerical model using the 2D finite difference code FLAC was developed and calibrated using laboratory tests to predict the soil behavior and consolidation settlements. The constitutive model impact for simulating the soft soil behavior is investigated. The results of analyses show that numerical analysis provided satisfactory predictions for the field performance during the construction of Radès la Goulette embankment. The obtained results show the effectiveness of PVD in the acceleration of the consolidation time. A comparison of numerical results with theoretical analysis was presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tunis%20soft%20soil" title="tunis soft soil">tunis soft soil</a>, <a href="https://publications.waset.org/abstracts/search?q=rad%C3%A8s%20bridge%20project" title=" radès bridge project"> radès bridge project</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated%20vertical%20drains" title=" prefabricated vertical drains"> prefabricated vertical drains</a>, <a href="https://publications.waset.org/abstracts/search?q=FLAC" title=" FLAC"> FLAC</a>, <a href="https://publications.waset.org/abstracts/search?q=acceleration%20of%20consolidation" title=" acceleration of consolidation"> acceleration of consolidation</a> </p> <a href="https://publications.waset.org/abstracts/146150/field-tests-and-numerical-simulation-of-tunis-soft-soil-improvement-using-prefabricated-vertical-drains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146150.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">123</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">126</span> The Effectiveness of Prefabricated Vertical Drains for Accelerating Consolidation of Tunis Soft Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ben%20Khalifa">Marwa Ben Khalifa</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeineb%20Ben%20Salem"> Zeineb Ben Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Wissem%20Frikha"> Wissem Frikha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the present work is to study the consolidation behavior of highly compressible Tunis soft soil “TSS” by means of prefabricated vertical drains (PVD’s) associated to preloading based on laboratory and field investigations. In the first hand, the field performance of PVD’s on the layer of Tunis soft soil was analysed based on the case study of the construction of embankments of “Radès la Goulette” bridge project. PVD’s Geosynthetics drains types were installed with triangular grid pattern until 10 m depth associated with step-by-step surcharge. The monitoring of the soil settlement during preloading stage for Radès La Goulette Bridge project was provided by an instrumentation composed by various type of tassometer installed in the soil. The distribution of water pressure was monitored through piezocone penetration. In the second hand, a laboratory reduced tests are performed on TSS subjected also to preloading and improved with PVD's Mebradrain 88 (Mb88) type. A specific test apparatus was designed and manufactured to study the consolidation. Two series of consolidation tests were performed on TSS specimens. The first series included consolidation tests for soil improved by one central drain. In thesecond series, a triangular mesh of three geodrains was used. The evolution of degree of consolidation and measured settlements versus time derived from laboratory tests and field data were presented and discussed. The obtained results have shown that PVD’s have considerably accelerated the consolidation of Tunis soft soil by shortening the drainage path. The model with mesh of three drains gives results more comparative to field one. A longer consolidation time is observed for the cell improved by a single central drain. A comparison with theoretical analysis, basically that of Barron (1948) and Carillo (1942), was presented. It’s found that these theories overestimate the degree of consolidation in the presence of PVD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tunis%20soft%20soil" title="tunis soft soil">tunis soft soil</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated%20vertical%20drains" title=" prefabricated vertical drains"> prefabricated vertical drains</a>, <a href="https://publications.waset.org/abstracts/search?q=acceleration%20of%20consolidation" title=" acceleration of consolidation"> acceleration of consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipation%20of%20excess%20pore%20water%20pressures" title=" dissipation of excess pore water pressures"> dissipation of excess pore water pressures</a>, <a href="https://publications.waset.org/abstracts/search?q=rad%C3%A8s%20bridge%20project" title=" radès bridge project"> radès bridge project</a>, <a href="https://publications.waset.org/abstracts/search?q=barron%20and%20carillo%E2%80%99s%20theories" title=" barron and carillo’s theories"> barron and carillo’s theories</a> </p> <a href="https://publications.waset.org/abstracts/146148/the-effectiveness-of-prefabricated-vertical-drains-for-accelerating-consolidation-of-tunis-soft-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146148.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">127</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">125</span> In vitro Comparison Study of Biologically Synthesized Cupper-Disulfiram Nanoparticles with Its Free Corresponding Complex as Therapeutic Approach for Breast and Liver Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20M.%20Abu-Serie">Marwa M.

In this study, Cu-NPs were fabricated by Streptomyces cyaneofuscatus through simultaneous bioreduction strategy of copper nitrate salt. The as-prepared Cu-NPs subjected to structural analysis; energy-dispersive X-ray spectroscopy, elemental mapping, X-ray diffraction, transmission electron microscopy, and ζ-potential. These biological synthesized Cu-NPs were mixed with disulfiram (DS), forming a nanocomplex of Cu-DS with a size of ~135 nm. The prepared nanocomplex (nanoCu-DS) exhibited higher anticancer activity than that of free complex of DS-Cu, Cu-NPs, and DS alone. This was illustrated by the lowest IC50 of nanoCu-DS (< 4 µM) against human breast and liver cancer cell lines comparing with DS-Cu, Cu-NPs, and DS (~8, 22.98-33.51 and 11.95-14.86, respectively). Moreover, flow cytometric analysis confirmed that higher apoptosis percentage range of nanoCu-DS-treated in MDA-MB 231, MCF-7, Huh-7, and HepG-2 cells (51.24-65.28%) than free complex of Cu-DS ( < 4.5%). Regarding inhibition potency of liver and breast cancer cell migration, no significant difference was recorded between free and nanocomplex. Furthermore, nanoCu-DS suppressed gene expression of β-catenine, Akt, and NF-κB and upregulated p53 expression (> 3, >15, > 5 and ≥ 3 folds, respectively) more efficiently than free complex (all ~ 1 fold) in MDA-MB 231 and Huh-7 cells. Our finding proved this prepared nano complex has a powerful anticancer activity relative to free complex, thereby offering a promising cancer treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biologically%20prepared%20Cu-NPs" title="biologically prepared Cu-NPs">biologically prepared Cu-NPs</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer%20cell%20lines" title=" breast cancer cell lines"> breast cancer cell lines</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer%20cell%20lines" title=" liver cancer cell lines"> liver cancer cell lines</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoCu-%20disulfiram" title=" nanoCu- disulfiram"> nanoCu- disulfiram</a> </p> <a href="https://publications.waset.org/abstracts/130507/in-vitro-comparison-study-of-biologically-synthesized-cupper-disulfiram-nanoparticles-with-its-free-corresponding-complex-as-therapeutic-approach-for-breast-and-liver-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130507.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">189</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">124</span> Beam, Column Joints Concrete in Seismic Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalifa%20Kherafa">Khalifa Kherafa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This east project consists in studying beam–column joints concrete subjected to seismic loads.

The main constituent is limestone, with subordinate dolomites and Shales. Reservoir quality is largely influenced by depositional environments and diagenesis processes. Generally the reservoir quality of Lower Beda Formation is low risk on the Inferred Horst and in the Southern Shelf where the Lower Beda formation comprises mainly of calcarenties. In the vicinity of the well GG1 the Lower Beda comprise mainly of argillaceous calcilutites and shale. The reservoir quality gradually improves from high risk to moderate risk towards KK1, LL1 and NN1 wells. The average gross thickness of Lower Beda Formation is about 300 ft. The net thickness varies from about 270 ft. in the E1-71 well to about 30 ft. in the vicinity of GG1-71 well. The net thickest of Lower Beda form a NNW-SSW trend with an average of 250 ft. the change in facies is due to change in the depositional environment, from lagoonal to shoal barrier to open marine affected the reservoir quality. The Upper Cretaceous Sirte Shale is the main source rock. It is developed within the three troughs surrounding the study area. S-Marada Trough to the N- E, Gerad Trough to the N N-W, and Abu Tummym Sub-basin to the S-W of the Inferred Horst. Sirte shale reaches 1000ft, of organically rich section. It has good organic contents over large area 2% to 3%. Hydrocarbon shows were encountered in several wells in Beda Formation this is an indication of vertical and lateral migration of hydrocarbon. The overlying Upper Paleocene Khalifa Formation is a transgressive shale, it is an effective regional top seal. Lithofacies variations in Khalifa Shale, from shales to limestones in the southern shelf in R1-71 well approximately 50-75% of the secession is limestone. About 47 million barrel of hydrocarbon recoverable reserves is expected to be trapped in structural and stratigraphic traps in Beda Formation in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sirte%20basin" title="Sirte basin">Sirte basin</a>, <a href="https://publications.waset.org/abstracts/search?q=Beda%20formation" title=" Beda formation"> Beda formation</a>, <a href="https://publications.waset.org/abstracts/search?q=concession%2071" title=" concession 71"> concession 71</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20play%20fairway%20analysis" title=" petroleum play fairway analysis"> petroleum play fairway analysis</a> </p> <a href="https://publications.waset.org/abstracts/159363/petroleum-play-fairway-analysis-of-the-middle-paleocene-lower-beda-formation-concession-71-south-central-sirt-basin-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159363.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">88</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">122</span> A Semantic E-Learning and E-Assessment System of Learners </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiem%20Ben%20Khalifa">Wiem Ben Khalifa</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalila%20Souilem"> Dalila Souilem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Neji"> Mahmoud Neji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evolutions of Social Web and Semantic Web lead us to ask ourselves about the way of supporting the personalization of learning by means of intelligent filtering of educational resources published in the digital networks.

Detecting Lynch Syndrome in individuals is crucial for early intervention and preventive measures. This study proposes a computational pipeline for Lynch Syndrome detection by integrating alignment, variant calling, and annotation. The pipeline leverages popular tools such as FastQC, Trimmomatic, BWA, bcftools, and ANNOVAR to process the input FASTQ file, perform quality trimming, align reads to the reference genome, call variants, and annotate them. It is believed that the computational pipeline was applied to a dataset of Lynch Syndrome cases, and its performance was evaluated. It is believed that the quality check step ensured the integrity of the sequencing data, while the trimming process is thought to have removed low-quality bases and adaptors. In the alignment step, it is believed that the reads were accurately mapped to the reference genome, and the subsequent variant calling step is believed to have identified potential genetic variants. The annotation step is believed to have provided functional insights into the detected variants, including their effects on known Lynch Syndrome-associated genes. The results obtained from the pipeline revealed Lynch Syndrome-related positions in the genome, providing valuable information for further investigation and clinical decision-making. The pipeline's effectiveness was demonstrated through its ability to streamline the analysis workflow and identify potential genetic markers associated with Lynch Syndrome. It is believed that the computational pipeline presents a comprehensive and efficient approach to Lynch Syndrome detection, contributing to early diagnosis and intervention. The modularity and flexibility of the pipeline are believed to enable customization and adaptation to various datasets and research settings.

The objective of the current study was to investigate the effect of feeding flaxseed on immune tissue weights. Cobb 500 broiler chickens were fed flaxseed at 15%, the control diet did not contain any flaxseed. Results showed that dietary supplementation with flaxseed did not affect the weights of the spleens of broiler chickens. However, it significantly lowered bursa weights (p<0.01), compared to the control diet. In addition, the bursae were thinner in appearance compared with bursii from chickens fed the control diets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bursa%20of%20fabricius" title="bursa of fabricius">bursa of fabricius</a>, <a href="https://publications.waset.org/abstracts/search?q=flaxseed" title=" flaxseed"> flaxseed</a>, <a href="https://publications.waset.org/abstracts/search?q=spleen" title=" spleen"> spleen</a>, <a href="https://publications.waset.org/abstracts/search?q=thymus" title=" thymus"> thymus</a> </p> <a href="https://publications.waset.org/abstracts/28247/do-immune-organ-weights-indicate-immunomodulation-of-polyunsaturated-fatty-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28247.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">444</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">115</span> Effect of Fire on Structural Behavior of Normal and High Strength Concrete Beams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20I.%20Arafa">Alaa I.

In the subsequent steps, these feature points are used to match two 3D point clouds in consecutive frames independent of their resolution. Our new motion vectors based dynamic alignment method then fully reconstruct a spatio-temporally coherent 3D animation. We perform extensive quantitative validation using novel error functions to analyze the results.

Firstly, the participation of banks in economic development focus around providing credit and services to generate revenues, which are then invested back into a local, national or international community. The specific roles banks play in the economic development of a small community differ from the role banks play in national or international economic development. Although the role can vary, factors such as access to credit and bank investment policies or practices remain constant, no matter the scope of economic development.

Many algorithms have been developed to detect and track moving vehicles. In fact, vehicle tracking in daytime and in nighttime cannot be approached with the same techniques, due to the extreme different illumination conditions. Consequently, traffic-monitoring systems are in need of having a component to differentiate between daytime and nighttime scenes. In this paper, a HSV-based day/night detector is proposed for traffic monitoring scenes. The detector employs the hue-histogram and the value-histogram on the top half of the image frame. Experimental results show that the extraction of the brightness features along with the color features within the top region of the image is effective for classifying traffic scenes. In addition, the detector achieves high precision and recall rates along with it is feasible for real time applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=day%2Fnight%20detector" title="day/night detector">day/night detector</a>, <a href="https://publications.waset.org/abstracts/search?q=daytime%2Fnighttime%20classification" title=" daytime/nighttime classification"> daytime/nighttime classification</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20classification" title=" image classification"> image classification</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20tracking" title=" vehicle tracking"> vehicle tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20monitoring" title=" traffic monitoring"> traffic monitoring</a> </p> <a href="https://publications.waset.org/abstracts/34948/daynight-detector-for-vehicle-tracking-in-traffic-monitoring-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34948.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">555</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">109</span> CO₂ Capture by Clay and Its Adsorption Mechanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jedli%20Hedi">Jedli Hedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedfi%20Hachem"> Hedfi Hachem</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdessalem%20Jbara"> Abdessalem Jbara</a>, <a href="https://publications.waset.org/abstracts/search?q=Slimi%20Khalifa"> Slimi Khalifa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural and modified clay were used as an adsorbent for CO2 capture. Sample of clay was subjected to acid treatments to improve their textural properties, namely, its surface area and pore volume. The modifications were carried out by heating the clays at 120 °C and then by acid treatment with 3M sulphuric acid solution at boiling temperature for 10 h. The CO2 adsorption capacities of the acid-treated clay were performed out in a batch reactor. It was found that the clay sample treated with 3M H2SO4 exhibited the highest Brunauer–Emmett–Teller (BET) surface area (16.29–24.68 m2/g) and pore volume (0.056–0.064 cm3/g). After the acid treatment, the CO2 adsorption capacity of clay increased. The CO2 adsorption capacity of clay increased after the acid treatment. The CO2 adsorption by clay, were characterized by SEM, FTIR, ATD-ATG and BET method. For describing the phenomenon of CO2 adsorption for these materials, the adsorption isotherms were modeled using the Freundlich and Langmuir models.

Map-reduce designed to support heterogeneous datasets. Apache Hadoop map-reduce used extensively to uncover hidden pattern like data mining, SQL, etc. The most important operation for data analysis is joining operation. But, map-reduce framework does not directly support join algorithm. This paper explains and compares two-way and multi-way map-reduce join algorithms for map reduce also we implement MR join Algorithms and show the performance of each phase in MR join algorithms. Our experimental results show that map side join and map merge join in two-way join algorithms has the longest time according to preprocessing step sorting data and reduce side cascade join has the longest time at Multi-Way join algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadoop" title="Hadoop">Hadoop</a>, <a href="https://publications.waset.org/abstracts/search?q=MapReduce" title=" MapReduce"> MapReduce</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-way%20join" title=" multi-way join"> multi-way join</a>, <a href="https://publications.waset.org/abstracts/search?q=two-way%20join" title=" two-way join"> two-way join</a>, <a href="https://publications.waset.org/abstracts/search?q=Ubuntu" title=" Ubuntu"> Ubuntu</a> </p> <a href="https://publications.waset.org/abstracts/82539/from-two-way-to-multi-way-a-comparative-study-for-map-reduce-join-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82539.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">487</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">105</span> Protein-Thiocyanate Composite as a Sensor for Iron III Cations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hosam%20El-Sayed">Hosam El-Sayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20%20Abou%20El-Kheir"> Amira Abou El-Kheir</a>, <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Mowafi"> Salwa Mowafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Abou%20Taleb"> Marwa Abou Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two proteinic biopolymers; namely keratin and sericin, were extracted from their respective natural resources by simple appropriate methods.

This technique attracted the concerning of researchers during the last two decades. This paper presents a simple uniaxial nonlinear finite element model (UNFEM) able to accurately estimate the load-carrying capacity, different failure modes and the interfacial stresses of reinforced concrete (RC) continuous beams flexurally strengthened with externally bonded FRP plates on the upper and lower fibers. Results of the proposed finite element (FE) model are verified by comparing them with experimental measurements available in the literature. The agreement between numerical and experimental results is very good. Considering fracture energy of adhesive is necessary to get a realistic load carrying capacity of continuous RC beams strengthened with FRP. This simple UNFEM is able to help design engineers to model their strengthened structures and solve their problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20beams" title="continuous beams">continuous beams</a>, <a href="https://publications.waset.org/abstracts/search?q=debonding" title=" debonding"> debonding</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20reinforced%20polymer" title=" fibre reinforced polymer"> fibre reinforced polymer</a> </p> <a href="https://publications.waset.org/abstracts/14425/external-strengthening-of-rc-continuous-beams-using-frp-plates-finite-element-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14425.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">482</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">101</span> Investigating the Potential of a Blended Format for the Academic Reading Module Course Redesign</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reham%20Niazi">Reham Niazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Helmy"> Marwa Helmy</a>, <a href="https://publications.waset.org/abstracts/search?q=Susanne%20Rizzo"> Susanne Rizzo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This classroom action research is designed to explore the possibility of adding effective online content to supplement and add learning value to the current reading module.

The EIS results showed that the charge transfer resistance (Rct) of LiFePO₄ was decreased by adding 10% PP polymerized in a situation to 153 vs. 1660  for bare LiFePO₄. The CV curves show that 10% PP added LiFePO₄ had higher electrochemical reactivity for lithium insertion and extraction than the un-doped material. The mean redox potential is E1/2 = 3.45 V vs. Li+/Li. The first discharge curve of the 10% poly pyrrole doped LiFePO₄ showed a mainly flat voltage plateau over the 3.45–3.5 V range, indicating the lithium extraction and insertion reactions between LiFePO₄ and FePO₄. A specific discharge capacity of cells prepared from in-situ 10% PP added LiFePO4to was about 210 vs. 65 mAhg-1 for bare LiFePO₄. <p class="card-text"><strong>Keywords:</strong> <a
