SDAVFs are present in the thoracolumbar region. The main goal of treatment must be to obliterate the shunting zone via superselective embolization with the usage of a liquid embolic agent. This study aims to evaluate endovascular technique as a safe and efficient approach for the treatment SDAVFs, especially with long-term follow-up clinical outcomes. Study Design: A retrospective clinical case study. From May 2010 to May 2017, 15 patients who had symptoms attributed to SDAVFs underwent the operation in the Departments of Neurosurgery in Suhag, Tanta, and Al-Azhar Universities and Interventional Radiology, Ain Shams University. All the patients had varying degrees of progressive spastic paraparesis with and without sphincteric disturbances. Endovascular embolization was used in all cases. Fourteen were males, with ages ranging from 45 to 74 years old. After the treatment, good outcome was found in five patients (33.3%), a moderate outcome was delineated in six patients (40 %), and four patients revealed a poor outcome (26.7%). Spinal AVF could be treated safely and effectively by the endovascular approach. Generally, there is no correlation between the disappearance of MRI abnormalities and significant clinical improvement. The preclinical state of the patient is directly proportional to the clinical outcome. Due to unexpected responses, embolization should be attempted even the patient is in a bad clinical condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spine" title="spine">spine</a>, <a href="https://publications.waset.org/abstracts/search?q=arteriovenous" title=" arteriovenous"> arteriovenous</a>, <a href="https://publications.waset.org/abstracts/search?q=fistula" title=" fistula"> fistula</a>, <a href="https://publications.waset.org/abstracts/search?q=endovascular" title=" endovascular"> endovascular</a>, <a href="https://publications.waset.org/abstracts/search?q=embolization" title=" embolization"> embolization</a> </p> <a href="https://publications.waset.org/abstracts/147643/embolization-of-spinal-dural-arteriovenous-fistulae-clinical-outcomes-and-long-term-follow-up-a-multicenter-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147643.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">108</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">1824</span> Synthesis, Characterization and Applications of Novel Hydrogels Based On Chitosan Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20H.%20Aboul-Ela">Mahmoud H.

This has led to the introduction of notions based on the separation of religion from ethics in recent decades. It is in conflict with the traditional view, which introduces ethics as raised from religion and religion as the most crucial credit for ethics. The purpose of this study is to investigate the elements of secular ethics from the perspective of Mostafa Malekian, seeking to achieve his notions. After examining the strengths of secular ethics parameters from the viewpoint of Malekian, this research found his ethics in his interpretation of the ideal life which he treats as ethics, got a very strong link with his secularist project known as rationality and spirituality. We will analyze, review, and critique his ethics in the following. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=secular%20ethics" title="secular ethics">secular ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Malakian" title=" Mostafa Malakian"> Mostafa Malakian</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20ethics" title=" global ethics"> global ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=rationality" title=" rationality"> rationality</a>, <a href="https://publications.waset.org/abstracts/search?q=spirituality" title=" spirituality"> spirituality</a> </p> <a href="https://publications.waset.org/abstracts/157214/secular-ethics-from-the-viewpoint-of-mostafa-malekian-analyze-review-and-critique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157214.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">1822</span> An Exponential Field Path Planning Method for Mobile Robots Integrated with Visual Perception</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Roman">Magdy Roman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Shoeib"> Mostafa Shoeib</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Rostom"> Mostafa Rostom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global vision, whether provided by overhead fixed cameras, on-board aerial vehicle cameras, or satellite images can always provide detailed information on the environment around mobile robots. In this paper, an intelligent vision-based method of path planning and obstacle avoidance for mobile robots is presented. The method integrates visual perception with a new proposed field-based path-planning method to overcome common path-planning problems such as local minima, unreachable destination and unnecessary lengthy paths around obstacles. The method proposes an exponential angle deviation field around each obstacle that affects the orientation of a close robot. As the robot directs toward, the goal point obstacles are classified into right and left groups, and a deviation angle is exponentially added or subtracted to the orientation of the robot. Exponential field parameters are chosen based on Lyapunov stability criterion to guarantee robot convergence to the destination. The proposed method uses obstacles' shape and location, extracted from global vision system, through a collision prediction mechanism to decide whether to activate or deactivate obstacles field. In addition, a search mechanism is developed in case of robot or goal point is trapped among obstacles to find suitable exit or entrance. The proposed algorithm is validated both in simulation and through experiments. The algorithm shows effectiveness in obstacles' avoidance and destination convergence, overcoming common path planning problems found in classical methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=path%20planning" title="path planning">path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=collision%20avoidance" title=" collision avoidance"> collision avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=convergence" title=" convergence"> convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20robots" title=" mobile robots"> mobile robots</a> </p> <a href="https://publications.waset.org/abstracts/84189/an-exponential-field-path-planning-method-for-mobile-robots-integrated-with-visual-perception" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1821</span> Cheiloscopy and Dactylography in Relation to ABO Blood Groups: Egyptian vs. Malay Populations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Hassan%20Abdel%20Aziz">Manal Hassan Abdel Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Mohamed%20Magdy%20Badr%20El%20Dine"> Fatma Mohamed Magdy Badr El Dine</a>, <a href="https://publications.waset.org/abstracts/search?q=Nourhan%20Mohamed%20Mohamed%20Saeed"> Nourhan Mohamed Mohamed Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Establishing association between lip print patterns and those of fingerprints as well as blood groups is of fundamental importance in the forensic identification domain. The first aim of the current study was to determine the prevalent types of ABO blood groups, lip prints and fingerprints patterns in both studied populations. Secondly, to analyze any relation found between the different print patterns and the blood groups, which would be valuable in identification purposes. The present study was conducted on 60 healthy volunteers, (30 males and 30 females) from each of the studied population. Lip prints and fingerprints were obtained and classified according to Tsuchihashi's classification and Michael Kuchen’s classification, respectively. The results show that the ulnar loop was the most frequent among both populations. Blood group A was the most frequent among Egyptians, while blood groups O and B were the predominant among Malaysians. Significant relations were observed between lip print patterns and fingerprint (in the second quadrant for Egyptian males and the first one for Malaysian). For Malaysian females, a statistically significant association was proved in the fourth quadrant. Regarding the blood groups, 89.5% of ulnar loops were significantly related to blood group A among Egyptian males. The results proved an association between the fingerprint pattern and the lip prints, as well as between the ABO blood group and the pattern of fingerprints. However, further researches with larger sample sizes need to be directed to approve the current results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABO" title="ABO">ABO</a>, <a href="https://publications.waset.org/abstracts/search?q=cheiloscopy" title=" cheiloscopy"> cheiloscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=dactylography" title=" dactylography"> dactylography</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptians" title=" Egyptians"> Egyptians</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysians" title=" Malaysians"> Malaysians</a> </p> <a href="https://publications.waset.org/abstracts/100037/cheiloscopy-and-dactylography-in-relation-to-abo-blood-groups-egyptian-vs-malay-populations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100037.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">219</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">1820</span> Synthesis, Characterization and Applications of Hydrogels Based on Chitosan Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20H.%20Abu%20Elella">Mahmoud H.

Consequently, this study is concerned with improving the quality attributes of gluten-free bread using different concentrations (0, 20, 40, 60 and 80ppm) of all maltogenic α-amylase (MA) and xylanase (XY) compared with wheat flour Balady bread and untreated gluten-free Balady bread (GFBB). Pasting properties, falling number, water activity, alkaline water retention capacity (AWRC) and sensory properties (fresh bread, after 24h, after 48h and after 72h) of gluten-free bread were evaluated. Additionally, the effect of merging different concentrations of maltogenic α-amylase and xylanase on stalling behavior (AWRC) and sensory properties of gluten-free Balady bread was investigated. The addition of MA led to a gradually decreased peak viscosity, breakdown, setback and pasting temperature of GFBB with the increasing level of MA. Maltogenic α-amylase and xylanase addition led to a reduction in the FN values compared to the untreated gluten-free sample, noting that the MA-treated samples showed a significant decrease compared to the XY-treated and untreated samples. Wheat flour Balady bread significantly showed a higher value of AWRC compared to untreated gluten-free Balady bread at different storage periods (zero time, after 24h, after 48h and after 72h). MA-treated samples showed higher water binding capacity and water activity (aw)in comparison with XY-treated samples, with significance during all storage periods. Concerning the overall acceptability during the third day, the highest score (4.6) was observed by the GFBB sample containing 40ppm MA, followed by 4.3, which was investigated by the GFBB sample containing 80ppm XY with no significance between them and with significance compared to the other samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=celiac%20disease" title="celiac disease">celiac disease</a>, <a href="https://publications.waset.org/abstracts/search?q=gluten-free%20products" title=" gluten-free products"> gluten-free products</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-stalling%20agents" title=" anti-stalling agents"> anti-stalling agents</a>, <a href="https://publications.waset.org/abstracts/search?q=maltogenic%20%CE%B1-amylase" title=" maltogenic α-amylase"> maltogenic α-amylase</a>, <a href="https://publications.waset.org/abstracts/search?q=xylanase" title=" xylanase"> xylanase</a> </p> <a href="https://publications.waset.org/abstracts/173389/new-insights-into-gluten-free-bread-staling-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173389.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">85</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">1818</span> Effectiveness of Myofascial Release Technique in Treatment of Sacroiliac Joint Hypo-Mobility in Postnatal Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.%20Abd%20El%20Rahim">Ahmed A.

Myofascial release technique (MFR) is an application of low-intensity, prolonged stretch to myofascial structures to improve function by increasing the sliding properties of restricted myofascial tissues. Purpose: This study was designed to investigate the effect of MFR on postnatal SIJ hypo-mobility. Materials and Methods: Fifty postnatal women complaining of SIJ hypo-mobility participated in this study. Their ages ranged from 26 to 35 yrs., and their body mass index (BMI) didn`t exceed 30 kg/m2. They were randomly assigned to two equal groups, group A (Gr. A) and group B (Gr. B). Both groups received three sessions per week for eight successive weeks. Gr. A received a traditional physical therapy program, while Gr. B received a traditional physical therapy program in addition to MFR. Doppler imaging of vibration was utilized to measure SIJ mobility pre- and post-intervention, and an electronic digital goniometer was used to measure back flexion and extension Range of motion. Results: Findings revealed a statistical improvement in post-intervention values of SIJ mobility in addition to trunk flexion and extension ROM in Gr. B compared to Gr. A (P<0.001). Conclusion: Adding MFR to traditional physical therapy programs is highly recommended in the treatment of SIJ hypo-mobility in postnatal women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sacroiliac%20hypo-mobility" title="sacroiliac hypo-mobility">sacroiliac hypo-mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=sacroiliac%20dysfunction" title=" sacroiliac dysfunction"> sacroiliac dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=myofascial%20release%20technique" title=" myofascial release technique"> myofascial release technique</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20physical%20therapy" title=" traditional physical therapy"> traditional physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=postnatal" title=" postnatal"> postnatal</a> </p> <a href="https://publications.waset.org/abstracts/157745/effectiveness-of-myofascial-release-technique-in-treatment-of-sacroiliac-joint-hypo-mobility-in-postnatal-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157745.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">102</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">1817</span> Eclectic Therapy in Approach to Clients’ Problems and Application of Multiple Intelligence Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sharof%20Mostafa">Mohamed Sharof Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Ahmadi"> Atefeh Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of traditional single modality psychotherapy and counselling approaches to clients’ problems are based on the application of one therapy in all sessions.

They represented the imagination of the deceased about his house in the afterlife, some of these soul houses were two floors, and the study will examine five models of soul houses which were discovered near Saqqara site by an Egyptian mission. These models had been transferred to The Grand Egyptian Museum (GEM) to be ready to display at the new museum. We focus upon five models of soul houses (GEM Numbers, 1276,1280,1281,1282,8711) they related to the old kingdom period. These models were all made of pottery, the five models have oval shape and were decorated with relief. Methodology: The study will focus on the development of soul houses during the different periods in ancient Egypt and the kinds of offerings which will reflect the economic situation in the Egyptian society and kinds of oils which were famous in ancient Egypt. Conclusion: This research focuses on the function of soul house and the kind of offerings which were put in it, This study will be useful for the heritage and ancient civilizations, specially when we talk about opening new museums like The Grand Egyptian Museum, which will display a new collection of soul houses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=archaeology%20study" title="archaeology study">archaeology study</a>, <a href="https://publications.waset.org/abstracts/search?q=grand%20egyptian%20museum" title=" grand egyptian museum"> grand egyptian museum</a>, <a href="https://publications.waset.org/abstracts/search?q=relief" title=" relief"> relief</a>, <a href="https://publications.waset.org/abstracts/search?q=soul%20houses" title=" soul houses"> soul houses</a> </p> <a href="https://publications.waset.org/abstracts/162980/archaeology-study-of-soul-houses-in-ancient-egypt-on-five-models-in-the-grand-egyptian-museum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162980.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">92</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">1815</span> Pre-Malignant Breast Lesions, Methods of Treatment and Outcome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mostafa">Ahmed Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mahmoud"> Mohamed Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesreen%20H.%20Hafez"> Nesreen H.

Aim of the study: Evaluation of premalignant lesions of the breast (DCIS), different treatment methods and outcome. Patients and methods: 60 patients with DCIS were studied from the period between 2005 to 2012, for 38 patients the primary surgical method was wide local resection (WLE) (63.3%) and the other cases (22 patients, 36.7%) had mastectomy, fourteen cases from those who underwent local excision received radiotherapy, while no adjuvant radiotherapy was given for those who underwent mastectomy. In case of hormonal receptor positive DCIS lesions hormonal treatment (Tamoxifen) was given after local control. Results: No difference in overall survival between mastectomy & breast conserving therapy (wide local excision and adjuvant radiotherapy), however local recurrence rate is higher in case of breast conserving therapy, also no role of Axillary evacuation in case of DCIS. The use of hormonal therapy decreases the incidence of local recurrence by about 98%. Conclusion: The main management of DCIS is local treatment (wide local excision and radiotherapy) with hormonal treatment in case of hormone receptor positive lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductal%20carcinoma%20in%20situ" title="ductal carcinoma in situ">ductal carcinoma in situ</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20treatment" title=" surgical treatment"> surgical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=radiotherapy" title=" radiotherapy"> radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20conserving%20therapy" title=" breast conserving therapy"> breast conserving therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=hormonal%20treatment" title=" hormonal treatment"> hormonal treatment</a> </p> <a href="https://publications.waset.org/abstracts/47658/pre-malignant-breast-lesions-methods-of-treatment-and-outcome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47658.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">321</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">1814</span> Digital Design and Fabrication: A Review of Trend and Its Impact in the African Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Al%20Araby">Mohamed Al Araby</a>, <a href="https://publications.waset.org/abstracts/search?q=Amany%20Salman"> Amany Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Amin"> Mostafa Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Madbully"> Mohamed Madbully</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Keraa"> Dalia Keraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Ali"> Mariam Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Marah%20Abdelfatah"> Marah Abdelfatah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Ahmed"> Mariam Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hassab"> Ahmed Hassab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the architecture, engineering, and construction (A.E.C.) industry have been exposed to important innovations, most notably the global integration of digital design and fabrication (D.D.F.) processes in the industry’s workflow. Despite this evolution in that sector, Africa was excluded from the examination of this development. The reason behind this exclusion is the preconceived view of it as a developing region that still employs traditional methods of construction. The primary objective of this review is to investigate the trend of digital construction (D.C.) in the African environment and the difficulties in its regular utilization of it. This objective can be attained by recognizing the notion of distributed computing in Africa and evaluating the impact of the projects deploying this technology on both the immediate and broader contexts. The paper’s methodology begins with the collection of data from 224 initiatives throughout Africa. Then, 50 of these projects were selected based on the criteria of the project's recency, typology variety, and location diversity. After that, a literature-based comparative analysis was undertaken. This study’s findings reveal a pattern of motivation for applying digital fabrication processes. Moreover, it is essential to evaluate the socio-economic effects of these projects on the population living near the analyzed subject. The last step in this study is identifying the influence on the neighboring nations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Africa" title="Africa">Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20construction" title=" digital construction"> digital construction</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20design" title=" digital design"> digital design</a>, <a href="https://publications.waset.org/abstracts/search?q=fabrication" title=" fabrication"> fabrication</a> </p> <a href="https://publications.waset.org/abstracts/159434/digital-design-and-fabrication-a-review-of-trend-and-its-impact-in-the-african-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159434.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">179</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">1813</span> Control of Microbial Pollution Using Biodegradable Polymer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20H.%20Abu%20Elella">Mahmoud H.

It is resulted by pathogenic microorganisms such as Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and other pathogenic strains. They cause a dangerous effect on human health, so great efforts have been exerted to produce new and effective antimicrobial agents. Nowadays, natural polysaccharides, such as chitosan and its derivatives are used as antimicrobial agents. The aim of our work is to synthesize of a biodegradable polymer such as N-quaternized chitosan (NQC) then Characterization of NQC by using different analysis techniques such as Fourier transform infrared (FTIR) and Scanning electron microscopy (SEM) and using it as an antibacterial agent against different pathogenic bacteria. Methods: Synthesis of NQC using dimethylsulphate. Results: FTIR technique exhibited absorption peaks of NQC, SEM images illustrated that surface of NQC was smooth and antibacterial results showed that NQC had a high antibacterial effect. Discussion: NQC was prepared and it was proved by FTIR technique and SEM images antibacterial results exhibited that NQC was an antibacterial agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agent" title="antimicrobial agent">antimicrobial agent</a>, <a href="https://publications.waset.org/abstracts/search?q=N-quaternized%20chitosan%20chloride" title=" N-quaternized chitosan chloride"> N-quaternized chitosan chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanocomposites" title=" silver nanocomposites"> silver nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20polyacrylate" title=" sodium polyacrylate"> sodium polyacrylate</a> </p> <a href="https://publications.waset.org/abstracts/58758/control-of-microbial-pollution-using-biodegradable-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58758.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">288</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">1812</span> Evaluation of Marwit Rod El Leqah Quartz Deposits As A Strategic Source of High Purity Quartz </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suzan%20Sami%20Ibrahim">Suzan Sami Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Gad%20Shahien"> Mohamed Gad Shahien</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Quarny%20Seliem"> Ali Quarny Seliem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Ragab%20Abukhadra"> Mostafa Ragab Abukhadra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pegmatite quartz deposits of Marwit Rod El Leqah area classify as medium purity quartz with 99.575 % average SiO2 content and therefore do not match the requirements of high technical applications (99.8 % SiO2 for solar cells, 99.8% SiO2 for electronics).

Amelogenesis, the process of enamel formation, is regulated by multiple genes to ensure normal, defect-free enamel. Defective enamel manifests as hypoplasia or as amelogenesis imperfecta (AI), which may occur in isolation or as part of a syndrome. This study presents 29 patients from 18 unrelated families (16 females and 13 males) who exhibited distinctive enamel abnormalities. We conducted thorough clinical examinations and requested laboratory and radiological investigations. Blood samples were collected for molecular analysis, utilizing a targeted panel for known AI variants and whole exome sequencing for unknown variants. Eleven variants linked to enamel anomalies were identified: four genes associated with isolated AI (WDR72, ACP4, SLC24A4, and FAM83H) and seven associated with syndromic forms, including enamel renal syndrome (FAM20A), tricho-dento-osseous syndrome (DLX3), Jalili syndrome (CNNM4), and others linked to neurological and mitochondrial disorders, skeletal dysplasia, and peroxisome disorders. Abnormal oral and dental phenotypes in individuals may indicate serious inherited disorders.

Different traditional methods rely on the length of the diaphysis of long bones of limbs, epiphyseal-diaphyseal union, fusion of the primary ossification centers as well as dental eruption. However, there is a growing need for the development of precise and reliable methods to estimate age, especially in cases where dismembered corpses, burnt bodies, purified or fragmented parts are recovered. Teeth are the hardest and indestructible structure in the human body. In recent years, assessment of pulp/tooth area ratio, as an indirect quantification of secondary dentine deposition has received a considerable attention. However, scanty work has been done in Egypt in terms of applicability of pulp/tooth ratio for age estimation. Aim of the Work: The present work was designed to assess the Cameriere’s method for age estimation from pulp/tooth ratio of maxillary canines, central and lateral incisors among a sample from Egyptian population. In addition, to formulate regression equations to be used as population-based standards for age determination. Material and Methods: The present study was conducted on 270 peri-apical X-rays of maxillary canines, central and lateral incisors (collected from 131 males and 139 females aged between 19 and 52 years). The pulp and tooth areas were measured using the Adobe Photoshop software program and the pulp/tooth area ratio was computed. Linear regression equations were determined separately for canines, central and lateral incisors. Results: A significant correlation was recorded between the pulp/tooth area ratio and the chronological age. The linear regression analysis revealed a coefficient of determination (R² = 0.824 for canine, 0.588 for central incisor and 0.737 for lateral incisor teeth). Three regression equations were derived. Conclusion: As a conclusion, the pulp/tooth ratio is a useful technique for estimating age among Egyptians. Additionally, the regression equation derived from canines gave better result than the incisors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20determination" title="age determination">age determination</a>, <a href="https://publications.waset.org/abstracts/search?q=canines" title=" canines"> canines</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20incisors" title=" central incisors"> central incisors</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20incisors" title=" lateral incisors"> lateral incisors</a>, <a href="https://publications.waset.org/abstracts/search?q=pulp%2Ftooth%20ratio" title=" pulp/tooth ratio"> pulp/tooth ratio</a> </p> <a href="https://publications.waset.org/abstracts/83832/age-estimation-from-upper-anterior-teeth-by-pulptooth-ratio-using-peri-apical-x-rays-among-egyptians" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83832.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">184</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">1809</span> Synthesis of Highly Valuable Fuel Fractions from Waste Date Seeds Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farrukh%20Jamil">Farrukh Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ala%27A%20H.%20Al-Muhtaseb"> Ala'A H.

The accumulation of dust on the solar panels significantly degrades output from these panels. Hence, solar PV panels have to be cleaned manually or using costly automated cleaning methods. This paper focuses on initiating cleaning actions when required to reduce maintenance costs. The cleaning actions are triggered only when the dust level exceeds a threshold value. The amount of dust accumulated on the PV panels is estimated using an artificial neural network (ANN). Experiments are conducted to collect the required data, which are used in the training of the ANN model. Then, this ANN model will be fed by the output power from solar panels, ambient temperature, and solar irradiance, and thus, it will be able to estimate the amount of dust accumulated on solar panels at these conditions. The model was tested on different case studies to confirm the accuracy of the developed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=dust" title=" dust"> dust</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20panels" title=" PV panels"> PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/131092/application-of-artificial-neural-network-in-initiating-cleaning-of-photovoltaic-solar-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131092.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">144</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">1807</span> The Possible Antioxidant, Hypoglycemic Effect and Antimicrobial Potential of Mangifera Indicia Leaves Aqueous Extract in Albino Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20B.%20Ahmed">Sahar B.

It was excavated by the Italian expedition in Qena (1935-1937). The box consists of 2pieces, the lid and the body. The inner side of the lid is decorated with ancient Egyptian inscriptions written with a black pigment. The box was made using several panels assembled together by wooden dowels and secured with plant ropes. The entire box is covered with a red pigment. This study aims to use analytical techniques in order to identify and have deep understanding for the box components. Moreover, the authors were significantly interested in using infrared reflectance transmission imaging (RTI-IR) to improve the hidden inscriptions on the lid. The identification of wood species included in this study. The visual observation and assessment were done to understand the condition of this box. 3Ddimensions and 2D programs were used to illustrate wood joints techniques. Optical microscopy (OM), X-ray diffraction (XRD), X-ray fluorescence portable (XRF) and Fourier Transform Infrared spectroscopy (FTIR) were used in this study in order to identify wood species, remains of insects bodies, red pigment, fibers plant and previous conservation adhesives, also RTI-IR technique was very effective to improve hidden inscriptions. The analysis results proved that wooden panels and dowels were identified as Acacia nilotica, wooden rail was Salix sp. the insects were identified as Lasioderma serricorne and Gibbium psylloids, the red pigment was Hematite, while the fiber plants were linen, previous adhesive was identified as cellulose nitrates. The historical study for the inscriptions proved that it’s a Hieratic writings of a funerary Text. After its transportation from the Egyptian museum storage to the wood conservation laboratory of the Grand Egyptian museum –conservation center (GEM-CC), conservation techniques were applied with high accuracy in order to restore the object including cleaning , consolidating of friable pigments and writings, removal of previous adhesive and reassembly, finally the conservation process that were applied were extremely effective for this box which became ready for display or storage in the grand Egyptian museum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scribe%20box" title="scribe box">scribe box</a>, <a href="https://publications.waset.org/abstracts/search?q=hieratic" title=" hieratic"> hieratic</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20program" title=" 3D program"> 3D program</a>, <a href="https://publications.waset.org/abstracts/search?q=Acacia%20nilotica" title=" Acacia nilotica"> Acacia nilotica</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose%20nitrate" title=" cellulose nitrate"> cellulose nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a> </p> <a href="https://publications.waset.org/abstracts/58881/analytical-study-and-conservation-processes-of-scribe-box-from-old-kingdom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58881.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">271</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">1805</span> BiFormerDTA: Structural Embedding of Protein in Drug Target Affinity Prediction Using BiFormer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Baghaarabani">Leila Baghaarabani</a>, <a href="https://publications.waset.org/abstracts/search?q=Parvin%20Razzaghi"> Parvin Razzaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mennatolla%20Magdy%20Mostafa"> Mennatolla Magdy Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Albaqsami"> Ahmad Albaqsami</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%20Warith%20Al%20Rushaidi"> Al Warith Al Rushaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Al%20Rawahi"> Masoud Al Rawahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predicting the interaction between drugs and their molecular targets is pivotal for advancing drug development processes. Due to the time and cost limitations, computational approaches have emerged as an effective approach to drug-target interaction (DTI) prediction. Most of the introduced computational based approaches utilize the drug molecule and protein sequence as input. This study does not only utilize these inputs, it also introduces a protein representation developed using a masked protein language model. In this representation, for every individual amino acid residue within the protein sequence, there exists a corresponding probability distribution that indicates the likelihood of each amino acid being present at that particular position. Then, the similarity between each pair of amino-acids is computed to create similarity matrix. To encode the knowledge of the similarity matrix, Bi-Level Routing Attention (BiFormer) is utilized, which combines aspects of transformer-based models with protein sequence analysis and represents a significant advancement in the field of drug-protein interaction prediction. BiFormer has the ability to pinpoint the most effective regions of the protein sequence that are responsible for facilitating interactions between the protein and drugs, thereby enhancing the understanding of these critical interactions. Thus, it appears promising in its ability to capture the local structural relationship of the proteins by enhancing the understanding of how it contributes to drug protein interactions, thereby facilitating more accurate predictions. To evaluate the proposed method, it was tested on two widely recognized datasets: Davis and KIBA. A comprehensive series of experiments was conducted to illustrate its effectiveness in comparison to cuttingedge techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BiFormer" title="BiFormer">BiFormer</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20language%20processing" title=" protein language processing"> protein language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=self-attention%20mechanism" title=" self-attention mechanism"> self-attention mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20affinity" title=" binding affinity"> binding affinity</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20target%20interaction" title=" drug target interaction"> drug target interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=similarity%20matrix" title=" similarity matrix"> similarity matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20masked%20representation" title=" protein masked representation"> protein masked representation</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20language%20model" title=" protein language model"> protein language model</a> </p> <a href="https://publications.waset.org/abstracts/194594/biformerdta-structural-embedding-of-protein-in-drug-target-affinity-prediction-using-biformer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194594.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">7</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">1804</span> Date Pits Oil Used as Potential Source for Synthesizing Jet Fuel and Green Diesel Fractions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farrukh%20Jamil">Farrukh Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ala%27a%20H.%20Al-Muhtaseb"> Ala'a H.

Solketal visual appearance is transparent and it is odorless organic liquid used as fuel additive for diesel to improve its cold flow properties. Condensation of bio-glycerol with bio-acetone in presence of beta zeolite has been done for synthesizing solketal. It was observed that glycerol conversion and selectivity of solketal was largely effected by temperature, as it increases from 40 ºC to 60 ºC the conversion of glycerol rises from 80.04 % to 94.26 % and selectivity of solketal from 80.0 % to 94.21 % but further increase in temperature to 100 ºC glycerol conversion reduced to 93.06 % and solketal selectivity to 92.08 %. At the optimum conditions, the bio-glycerol conversion and solketal yield were about 94.26% and 94.21wt% respectively.

Solketal visual appearance is transparent, and it is odorless organic liquid used as a fuel additive for diesel to improve its cold flow properties. Condensation of bio-glycerol with bio-acetone in presence of beta zeolite has been done for synthesizing solketal. It was observed that glycerol conversion and selectivity of solketal was largely effected by temperature, as it increases from 40 ºC to 60 ºC the conversion of glycerol rises from 80.04 % to 94.26 % and selectivity of solketal from 80.0 % to 94.21 % but further increase in temperature to 100 ºC glycerol conversion reduced to 93.06 % and solketal selectivity to 92.08 %. At the optimum conditions, the bio-glycerol conversion and solketal yield were about 94.26% and 94.21wt% respectively. This process offers an attractive route for converting bio-glycerol, the main by-product of biodiesel to solketal with bio-acetone; a value-added green product with potential industrial applications as a valuable green fuel additive or combustion promoter for gasoline/diesel engines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-glycerol" title="bio-glycerol">bio-glycerol</a>, <a href="https://publications.waset.org/abstracts/search?q=catalyst" title=" catalyst"> catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20additive" title=" green additive"> green additive</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a> </p> <a href="https://publications.waset.org/abstracts/65166/synthesis-of-oxygenated-fuel-additive-from-bio-glycerol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65166.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">242</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">1801</span> Sudan’s Approach to Knowledge Management in Disaster Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdalla%20Elamein%20Boshara">Mohamed Abdalla Elamein Boshara</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Charles%20Woods"> Peter Charles Woods</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Eldin%20Mohamed%20Elshaiekh"> Nour Eldin Mohamed Elshaiekh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Management has become very important for Disaster Management response and planning.

The evolution of online-based multimedia data poses new challenges in storing and querying large amounts of data for online recommender systems. Graph data models have been shown to be more efficient than relational data models for processing complex data. This paper will explain the key differences between graph and relational databases, their strengths and weaknesses, and why using graph databases is the best technology for building a realtime recommendation system. Also, The paper will discuss several similarity metrics algorithms that can be used to compute a similarity score of pairs of nodes based on their neighbourhoods or their properties. Finally, the paper will discover how NLP strategies offer the premise to improve the accuracy and coverage of realtime recommendations by extracting the information from the stored unstructured knowledge, which makes up the bulk of the world’s data to enrich the graph database with this information. As the size and number of data items are increasing rapidly, the proposed system should meet current and future needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graph%20databases" title="graph databases">graph databases</a>, <a href="https://publications.waset.org/abstracts/search?q=NLP" title=" NLP"> NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20systems" title=" recommendation systems"> recommendation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=similarity%20metrics" title=" similarity metrics"> similarity metrics</a> </p> <a href="https://publications.waset.org/abstracts/163018/recommender-system-based-on-mining-graph-databases-for-data-intensive-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163018.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">104</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">1799</span> Embarrassment as a Trigger Factor of Code Switching From Arabic to English in Egypt: A Case Study in Sociolinguistic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samar%20Mohamed%20Magdy%20Abdelrahim">Samar Mohamed Magdy Abdelrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is an attempt to investigate the phenomenon of code-switching that takes place between Arabic and English in social discourse among high, well-educated, and young people in Egypt. The study aims at digging deeper to extract the trigger factors of such occurrences, namely when people encounter embarrassing situations in their daily conversations. Nowadays, most young Egyptians tend to use English words in certain situations that might make them feel embarrassed. To disguise their feelings and soften the impact of these words in the context, they code-switch (CS) from Arabic into English. To obtain accurate results, the study utilized a quantitative analysis approach that combines personal observations and a questionnaire to examine the phenomenon appropriately. The questionnaire was designed to categorize different types of embarrassing topics to be evaluated by participants. These topics include certain parts of the human body, types of clothes, taboo words, and specific medical conditions. Many studies have examined the use of CS as a prestigious way of communicating and expressing solidarity between Arabic and English. Other studies have dealt with switches that take place in classrooms. However, not many studies have paid attention to this angle of CS, especially in Egypt. The results conclude that gender and the circumstances that surround the conversation are essential factors of CS since females tend to switch codes more than males in embarrassing situations. According to the study, CS serves the socio-pragmatic function in terms of helping young, well-educated bilinguals express themselves in a second language that would be distressing in the first. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code-switching" title="code-switching">code-switching</a>, <a href="https://publications.waset.org/abstracts/search?q=embarrassment" title=" embarrassment"> embarrassment</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic" title=" Arabic"> Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=English" title=" English"> English</a> </p> <a href="https://publications.waset.org/abstracts/163291/embarrassment-as-a-trigger-factor-of-code-switching-from-arabic-to-english-in-egypt-a-case-study-in-sociolinguistic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163291.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">97</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">1798</span> The Digital Library and Its Influential Role in Developing the Establishment of the Grand Egyptian Museum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haitham%20Magdy%20Hamad">Haitham Magdy Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ahmed%20Madkour"> Mohamed Ahmed Madkour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The essential role of the digital library in developing museum display methods, recording ancient Egyptian antiquities, facilitating scientific research, and storing antiquities in the Grand Egyptian Museum, which helped and saved a lot of time and money spent to equip the Grand Egyptian Museum.

This study was aimed to evaluate the prevalence of polypharmacy in elderly Saudi cardiac patient. A retrospective observational study was carried out at the department of CCU and cardiology unit of the King Fahad cardiac centre (KFCC) in King Khalid university hospital from May 2012 to October 2012. All Parameters was analyzed by using Statistical Packages for Social Science (SPSS) to conclude the result; tests of association were performed using the chi-square statistic. The mean age of patients was 70.1 ± 7.75 years, more than half 83 (51.6%) were males. The highest frequency of chronic diseases found were hypertension (91.0%) followed by, dyslipidemia (74.9%), and diabetes mellitus. Results showed that 82% had polypharmacy (>4 drugs) during the study period, and 47.9% had major polypharmacy. The incidence of inappropriate drug use was found to be higher with men than female (p = 0.984). In conclusion, this study revealed that high prevalence of polypharmacy and potentially inappropriate medications in elderly Saudi cardiac inpatients. <p class="card-text"><strong>Keywords:</strong>
