In-vitro cytotoxic activity against breast cancer cell line MCF-7 was investigated, with an IC50 of 54 ug/ml. In-silico molecular docking using ellagic acid, gallagic acid, and Punicalagin as model compounds identified in pomegranate rind extract confirmed the intriguing anti-estrogenic action of the key polyphenolic components in pomegranate rind extract. Surprisingly, taxol showed low activity compared to pomegranate compounds as ERα antagonist and ERβ agonist. Pomegranate rind extract enhanced apoptosis of breast cancer cells through upregulation of the caspase-3 expression and downregulation of NF-κB transcription factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPLC-MS%2FMS" title="HPLC-MS/MS">HPLC-MS/MS</a>, <a href="https://publications.waset.org/abstracts/search?q=pomegranate%20rind" title=" pomegranate rind"> pomegranate rind</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=MCF-7" title=" MCF-7"> MCF-7</a>, <a href="https://publications.waset.org/abstracts/search?q=ER" title=" ER"> ER</a>, <a href="https://publications.waset.org/abstracts/search?q=caspase-3" title=" caspase-3"> caspase-3</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-kB" title=" NF-kB"> NF-kB</a> </p> <a href="https://publications.waset.org/abstracts/163413/triggering-apoptosis-to-uproot-breast-cancer-hplc-msms-profiling-in-vitro-and-in-silico-fascinating-results-of-polyphenolics-in-pomegranate-rind-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163413.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">116</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">290</span> Application of Bacteriophage and Essential Oil to Enhance Photocatalytic Efficiency </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myriam%20Ben%20Said">Myriam Ben Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhekra%20Trabelsi"> Dhekra Trabelsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Achouri"> Faouzi Achouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ben%20Saad"> Marwa Ben Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Latifa%20Bousselmi"> Latifa Bousselmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ghrabi"> Ahmed Ghrabi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This present study suggests the use of biological and natural bactericide, cheap, safe to handle, natural, environmentally benign agents to enhance the conventional wastewater treatment process. In the same sense, to highlight the enhancement of wastewater photocatalytic treatability, we were used virulent bacteriophage(s) and essential oils (EOs). The pre-phago-treatment of wastewater with lytic phage(s), leads to a decrease in bacterial density and, consequently, limits the establishment of intercellular communication (QS), thus preventing biofilm formation and inhibiting the expression of other virulence factors after photocatalysis. Moreover, to increase the photocatalytic efficiency, we were added to the secondary treated wastewater 1/1000 (w/v) of EO of thyme (T. vulgaris). This EO showed in vitro an anti-biofilm activity through the inhibition of plonctonic cell mobility and their attachment on an inert surface and also the deterioration of the sessile structure. The presence of photoactivatable molecules (photosensitizes) in this type of oil allows the optimization of photocatalytic efficiency without hazards relayed to dyes and chemicals reagent. The use of ‘biological and natural tools’ in combination with usual water treatment process can be considered as a safety procedure to reduce and/or to prevent the recontamination of treated water and also to prevent the re-expression of virulent factors by pathogenic bacteria such as biofilm formation with friendly processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm" title="biofilm">biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oil" title=" essential oil"> essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=phage" title=" phage"> phage</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/92850/application-of-bacteriophage-and-essential-oil-to-enhance-photocatalytic-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92850.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">154</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">289</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">288</span> Enhancing the Performance of Bug Reporting System by Handling Duplicate Reporting Reports: Artificial Intelligence Based Mantis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afshan%20Saad">Afshan Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saad"> Muhammad Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shah%20Muhammad%20Emaduddin"> Shah Muhammad Emaduddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bug reporting systems are most important tool that guides regarding different maintenance activities in software engineering. Duplicate bug reports which describe the bugs and issues in bug reporting system repository increases processing time of bug triage that monitors all such activities and software programmers who are working and spending time on reports which were assigned by triage. These reports can reveal imperfections and degrade software quality. As there is a number of the potential duplicate bug reports increases, the number of bug reports in bug repository increases. Identifying duplicate bug reports help in decreasing development work load in fixing defects. However, it is difficult to manually identify all possible duplicates because of the huge number of already reported bug reports. In this paper, an artificial intelligence based system using Mantis is proposed to automatically detect duplicate bug reports. When new bugs are submitted to repository triages will mark it with a tag. It will investigate that whether it is a duplicate of an existing bug report by matching or not. Reports with duplicate tags will be eliminated from the repository which not only will improve the performance of the system but can also save cost and effort waste on bug triage and finding the duplicate bug. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bug%20tracking" title="bug tracking">bug tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=triager" title=" triager"> triager</a>, <a href="https://publications.waset.org/abstracts/search?q=tool" title=" tool"> tool</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20assurance" title=" quality assurance"> quality assurance</a> </p> <a href="https://publications.waset.org/abstracts/102595/enhancing-the-performance-of-bug-reporting-system-by-handling-duplicate-reporting-reports-artificial-intelligence-based-mantis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102595.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">193</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> Computational Pipeline for Lynch Syndrome Detection: Integrating Alignment, Variant Calling, and Annotations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rofida%20Gamal">Rofida Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Mohammed"> Mostafa Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Adel"> Mariam Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Gamal"> Marwa Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20kamal"> Marwa kamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Saber"> Ayat Saber</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Mamdouh"> Maha Mamdouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Emad"> Amira Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ramadan"> Mai Ramadan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lynch Syndrome is an inherited genetic condition associated with an increased risk of colorectal and other cancers. 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. Further optimization and validation are believed to be necessary to enhance performance and applicability across diverse populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lynch%20Syndrome" title="Lynch Syndrome">Lynch Syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20pipeline" title=" computational pipeline"> computational pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=alignment" title=" alignment"> alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=variant%20calling" title=" variant calling"> variant calling</a>, <a href="https://publications.waset.org/abstracts/search?q=annotation" title=" annotation"> annotation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20markers" title=" genetic markers"> genetic markers</a> </p> <a href="https://publications.waset.org/abstracts/178986/computational-pipeline-for-lynch-syndrome-detection-integrating-alignment-variant-calling-and-annotations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178986.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">76</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">286</span> Tracking Maximum Power Point Utilizing Artificial Immunity System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ahmed%20Abd%20El%20Hamied">Marwa Ahmed Abd El Hamied</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper In this paper, a new technique based on Artificial Immunity System (AIS) technique has been developed to track Maximum Power Point (MPP).

We can check this for structural building and significantly more so in the quick-paced universe of data innovation and programming designing. The lithe philosophies, similar to Scrum, have a devoted advance in the process that objectives the enhancement of the improvement procedure and programming items. Pivotal to process enhancement is to pick up data that grants you to assess the condition of the procedure and its items. From the status data, you can design activities for the upgrade and furthermore assess the accomplishment of those activities. This investigation builds a model that measures the product nature of the improvement procedure. The product quality is dependent on the useful and auxiliary nature of the product items, besides the nature of the advancement procedure is likewise vital to enhance programming quality. Utilitarian quality covers the adherence to client prerequisites, while the auxiliary quality tends to the structure of the product item's source code with reference to its practicality. The procedure quality is identified with the consistency and expectedness of the improvement procedure. The product quality model is connected in a business setting by social occasion the information for the product measurements in the model. To assess the product quality model, we investigate the information and present it to the general population engaged with the light-footed programming improvement process. The outcomes from the application and the client input recommend that the model empowers a reasonable evaluation of the product quality and that it very well may be utilized to help the persistent enhancement of the advancement procedure and programming items. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agile%20SDLC%20Tools" title="Agile SDLC Tools">Agile SDLC Tools</a>, <a href="https://publications.waset.org/abstracts/search?q=Agile%20Software%20development" title=" Agile Software development"> Agile Software development</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20value" title=" business value"> business value</a>, <a href="https://publications.waset.org/abstracts/search?q=enterprise%20applications" title=" enterprise applications"> enterprise applications</a>, <a href="https://publications.waset.org/abstracts/search?q=IBM" title=" IBM"> IBM</a>, <a href="https://publications.waset.org/abstracts/search?q=IBM%20Rational%20Team%20Concert" title=" IBM Rational Team Concert"> IBM Rational Team Concert</a>, <a href="https://publications.waset.org/abstracts/search?q=RTC" title=" RTC"> RTC</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20quality" title=" software quality"> software quality</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20metrics" title=" software metrics"> software metrics</a> </p> <a href="https://publications.waset.org/abstracts/103463/adding-business-value-in-enterprise-applications-through-quality-matrices-using-agile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103463.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">174</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">281</span> Ant System with Acoustic Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saad%20Bougrine">Saad Bougrine</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Ouchraa"> Salma Ouchraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Belaid%20Ahiod"> Belaid Ahiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhakim%20Ameur%20El%20Imrani"> Abdelhakim Ameur El Imrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ant colony optimization is an ant algorithm framework that took inspiration from foraging behaviour of ant colonies.

Both cystoscopy and urine cytology used in detecting bladder cancer suffer from drawbacks where cystoscopy is an invasive method and urine cytology shows low sensitivity in low grade tumors. This study validates easier and less time-consuming techniques to evaluate the value of combined use of angiogenin and clusterin in comparison and combination with voided urine cytology in the detection of bladder cancer patients. This study includes malignant (bladder cancer patients, n= 50), benign (n=20), and healthy (n=20) groups. The studied groups were subjected to cystoscopic examination, detection of bilharzial antibodies, urine cytology, and estimation of urinary angiogenin and clusterin by ELISA. The overall sensitivity and specifcity were 66% and 75% for angiogenin, 70% and 82.5% for clusterin and 46% and 80% for voided urine cytology.

PP was prepared with LiFePO₄ in different ways, such as chemically dispersion, insinuation polymerization, and electrochemically polymerization. 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 href="https://publications.waset.org/abstracts/search?q=liFePO%E2%82%84" title="liFePO₄">liFePO₄</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20pyrrole%20addition" title="poly pyrrole addition">poly pyrrole addition</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20electrode" title=" positive electrode"> positive electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20battery" title=" lithium battery"> lithium battery</a> </p> <a href="https://publications.waset.org/abstracts/142587/study-the-role-effect-of-poly-pyrrole-on-lifepo4-as-positive-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142587.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">208</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">267</span> A Smart Visitors’ Notification System with Automatic Secure Door Lock Using Mobile Communication Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabail%20Shafique%20Satti">Rabail Shafique Satti</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Ejaz"> Sidra Ejaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Madiha%20Arshad"> Madiha Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Khalid"> Marwa Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadia%20Majeed"> Sadia Majeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents the development of an automated security system to automate the entry of visitors, providing more flexibility of managing their record and securing homes or workplaces.

Menopause is natural physiological changes primary because of decline of ovaries function with age which leads to decrease of estrogen hormone production which is the main hormone for bone continuous remodeling for bone density maintenance. Exercise increase stimulation of bone growth to keep bone mass by the effect of the mechanical stimulation, antigravity loading and stress exerted on musculoskeletal muscles. Purpose: This study aimed to determine the effect of aerobic exercise on estrogen hormone and bone mineral density (BMD) in osteoporotic women and the correlation between the estrogen and BMD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osteoporosis" title="Osteoporosis">Osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Postmenopause" title=" Postmenopause"> Postmenopause</a>, <a href="https://publications.waset.org/abstracts/search?q=Aerobic%20exercise" title=" Aerobic exercise"> Aerobic exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=DEXA" title=" DEXA"> DEXA</a>, <a href="https://publications.waset.org/abstracts/search?q=Serum%20Estrogen" title=" Serum Estrogen"> Serum Estrogen</a> </p> <a href="https://publications.waset.org/abstracts/166825/effect-of-aerobic-exercise-on-estrogen-hormone-and-bone-mineral-density-in-osteoporotic-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166825.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">264</span> Analysis of Joint Source Channel LDPC Coding for Correlated Sources Transmission over Noisy Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ben%20Abdessalem">Marwa Ben Abdessalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Zribi"> Amin Zribi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Bouall%C3%A8gue"> Ammar Bouallègue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a Joint Source Channel coding scheme based on LDPC codes is investigated. We consider two concatenated LDPC codes, one allows to compress a correlated source and the second to protect it against channel degradations. The original information can be reconstructed at the receiver by a joint decoder, where the source decoder and the channel decoder run in parallel by transferring extrinsic information. We investigate the performance of the JSC LDPC code in terms of Bit-Error Rate (BER) in the case of transmission over an Additive White Gaussian Noise (AWGN) channel, and for different source and channel rate parameters. We emphasize how JSC LDPC presents a performance tradeoff depending on the channel state and on the source correlation. We show that, the JSC LDPC is an efficient solution for a relatively low Signal-to-Noise Ratio (SNR) channel, especially with highly correlated sources. Finally, a source-channel rate optimization has to be applied to guarantee the best JSC LDPC system performance for a given channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AWGN%20channel" title="AWGN channel">AWGN channel</a>, <a href="https://publications.waset.org/abstracts/search?q=belief%20propagation" title=" belief propagation"> belief propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20source%20channel%20coding" title=" joint source channel coding"> joint source channel coding</a>, <a href="https://publications.waset.org/abstracts/search?q=LDPC%20codes" title=" LDPC codes"> LDPC codes</a> </p> <a href="https://publications.waset.org/abstracts/62721/analysis-of-joint-source-channel-ldpc-coding-for-correlated-sources-transmission-over-noisy-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62721.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">357</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">263</span> Kinetics and Mechanism of Oxidation of Some Amino Acids by Peroxodisulphate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelmahmod%20Saad">Abdelmahmod Saad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study two amino acids were chosen (DL.alanine,DL.serine) to determine their effect on dissociation of S2O8-2 ino. As the reaction was very slow, Ag+ ino was used as a catalyst. The kinetics measurement showed that the reactions in both cases were found in the first order with respect to S2O8-2, half order with respect to Ag+ and zero order with respect to substrates. Mechanisms were proposed for these reactions according to the determined orders. The energy of activation (AE) was determined for each reaction, and was found to by 30.50 k JmoI-1 in case of DL.

Using panel data estimates for 19 European countries during the period 2000-2012, this article showed the role of institutional factors, especially the role of employment policies implementation based on three variables: the allocation of resources for the implementation of policies, continuity and timing in the implementation of policies to capture their effectiveness on the labor market. Empirical results shows favor effect of training, employment incentives, sheltered employment and rehabilitation and direct job creation on the entire population employment growth. Results shows also that start-up incentives seems to be more effective in increasing employment than other types of policies. Importantly, two aspects are important in terms of implementation: public expenditure on program administration, e.g. (PES) watches the most favorable aspect and the continuity of policies implemented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20labor%20market%20policies" title="active labor market policies">active
