Wadaan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, a great attention has been paid to the use of dietary carbohydrates as prebiotic functional foods. Among the new commercially available products, fructooligosaccharides (FOS), which are microbial produced from sucrose, have attracted special interest due to their valuable properties and, thus, have a great economic potential for the sugar industrial branch. They are non-cariogenic sweeteners of low caloric value, as they are not hydrolyzed by the gastro-intestinal enzymes, promoting selectively the growth of the bifidobacteria in the colon, helping to eliminate the harmful microbial species to human and animal health and preventing colon cancer. FOS has been also found to reduce cholesterol, phospholipids and triglyceride levels in blood. FOS has been mainly produced by microbial fructosyltransferase (FTase) enzymes. The present work outlines bioprocess optimization for different cultivation parameters affecting the production of FTase by Penicillium aurantiogriseum AUMC 5605. The optimization involves both traditional as well as fractional factorial design approaches. Additionally, the production process will be compared under batch and fed-batch conditions. Finally, the optimized process conditions will be applied to 5-L stirred tank bioreactor cultivations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prebiotics" title="prebiotics">prebiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=fructooligosaccharides" title=" fructooligosaccharides"> fructooligosaccharides</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=cultivation" title=" cultivation"> cultivation</a> </p> <a href="https://publications.waset.org/abstracts/3181/fructooligosaccharide-prebiotics-optimization-of-different-cultivation-parameters-on-their-microbial-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3181.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">387</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">102</span> A Novel Multi-Objective Park and Ride Control Scheme Using Renewable Energy Sources: Cairo Case Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Elsayed%20Lotfy%20Elsayed%20Abouzeid">Mohammed Elsayed Lotfy Elsayed Abouzeid</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomonobu%20Senjyu"> Tomonobu Senjyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel multi-objective park and ride control approach is presented in this research. Park and ride will encourage the owners of the vehicles to leave their cars in the nearest points (on the edges of the crowded cities) and use public transportation facilities (train, bus, metro, or mon-rail) to reach their work inside the crowded city. The proposed control scheme is used to design electric vehicle charging stations (EVCS) to charge 1000 electric vehicles (EV) during their owners' work time. Cairo, Egypt is used as a case study. Photovoltaic (PV) and battery energy storage system (BESS) are used to meet the EVCS demand. Two multi-objective optimization techniques (MOGA and epsilon-MOGA) are utilized to get the optimal sizes of PV and BESS so as to meet the load demand and minimize the total life cycle cost. Detailed analysis and comparison are held to investigate the performance of the proposed control scheme using MATLAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Battery%20%20Energy%20Storage%20System" title="Battery Energy Storage System">Battery Energy Storage System</a>, <a href="https://publications.waset.org/abstracts/search?q=Electric%20Vehicle" title=" Electric Vehicle"> Electric Vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20and%20Ride" title=" Park and Ride"> Park and Ride</a>, <a href="https://publications.waset.org/abstracts/search?q=Photovoltaic" title=" Photovoltaic"> Photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=Multi-objective" title=" Multi-objective"> Multi-objective</a> </p> <a href="https://publications.waset.org/abstracts/123793/a-novel-multi-objective-park-and-ride-control-scheme-using-renewable-energy-sources-cairo-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123793.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">101</span> CAG Repeat Polymorphism of Androgen Receptor and Female Sexual Functions in Egyptian Female Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azza%20Gaber%20Farag">Azza Gaber Farag</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Atta%20Shehata"> Yasser Atta Shehata</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Elsayed%20Elghazouly"> Sara Elsayed Elghazouly</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Elsayed%20Elshaib"> Mustafa Elsayed Elshaib</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesreen%20Gamal%20Elden%20Elhelbawy"> Nesreen Gamal Elden Elhelbawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Androgen receptor (AR) polymorphism in cytosine adenineguanine (CAG) repeat has an effect on the functional capacity of AR in males. However, little researches in this field are available regarding female sexual function. Aim: To investigate the possible link between polymorphism in the CAG repeat of AR gene and female sexual function in a sample of the Egyptian population. Materials and methods: 500 Egyptian married females completed a questionnaire regarding sociodemographic, reproductive, and sexual data. AR CAG repeat length was analyzed for those having female sexual dysfunctions (FSD) using real-time PCR. Results: The most sensitive domain to AR CAG repeat length was the orgasm domain that showed significant positive correlations with short allele (p=0.001), long allele (p=.015), biallellic mean (p=.000), and X weighted biallelic mean (p=.000). The satisfaction domain had significant positive correlations with the biallelic mean (p=.035), and the X weighted biallelic mean (p=. 032). However, the pain domain was of significant negative correlations with AR polymorphism of short allele (p=.002), biallelic mean (p=.013), and X weighted biallelic mean (p = . 011). Conclusions: AR polymorphism could represent a non-negligible aspect in female sexual function. The lower AR CAG repeat polymorphism was of significant impact on FSD, affecting mainly female orgasm followed by pain disorders that finally reflected On her sexual satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female%20sexual%20dysfunction" title="female sexual dysfunction">female sexual dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=androgen%20receptor" title=" androgen receptor"> androgen receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=CAG%20repeat%20polymorphism" title=" CAG repeat polymorphism"> CAG repeat polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=androgen" title=" androgen"> androgen</a> </p> <a href="https://publications.waset.org/abstracts/142676/cag-repeat-polymorphism-of-androgen-receptor-and-female-sexual-functions-in-egyptian-female-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142676.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">182</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">100</span> Snails and Fish as Pollution Biomarkers in Lake Manzala and Laboratory C: Laboratory Exposed Snails to Chemical Mixtures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20M.%20M.%20El-Khayat">Hanaa M.

The impacts of these tested chemicals, individual and mixtures, on liver and kidney functions, antioxidant enzymes, complete blood picture, and tissue histology were studied. Results showed that Cu was proved to be the highly toxic against snails than Zn and Pb where LC<sub>50</sub> values were 1.362, 213.198 and 277.396 ppm, respectively. Also, <em>B. alexandrina</em> snails exposed to the mixture of HM (¼ LC<sub>5</sub> Cu, Pb and Zn) showed the highest bioaccumulation of Cu and Zn in their whole tissue, the most significant increase in AST, ALT & ALP activities and the highest significant levels of total protein, albumin and globulin. Results showed significant alterations in CAT activity in snail tissue extracts while snail samples exposed to most experimental tests showed significant increase in GST activity. Snail samples that exposed to HM mixtures showed a significant decrease in total hemocytes count while snail samples that exposed to mixtures containing A & D showed a significant increase in total hemocytes and Hyalinocytes. Histopathological alterations in snail samples exposed to individual HM and their mixtures for 4 weeks showed degeneration, edema, hyper trophy and vaculation in head-foot muscle, degeneration and necrotic changes in the digestive gland and accumulation in most tested organs. Also, the hermaphrodite gland showed mature ova with irregular shape and reduction in sperm number. In conclusion, the resulted damage and alterations in <em>B. alexandrina</em> studied parameters can be used as bioindicators to the presence of pollutants in its habitats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biomphalaria" title="Biomphalaria">Biomphalaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn" title=" Zn"> Zn</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu" title=" Cu"> Cu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pb" title=" Pb"> Pb</a>, <a href="https://publications.waset.org/abstracts/search?q=AST" title=" AST"> AST</a>, <a href="https://publications.waset.org/abstracts/search?q=ALT" title=" ALT"> ALT</a>, <a href="https://publications.waset.org/abstracts/search?q=ALP" title=" ALP"> ALP</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20protein%20albumin" title=" total protein albumin"> total protein albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=globulin" title=" globulin"> globulin</a>, <a href="https://publications.waset.org/abstracts/search?q=CAT" title=" CAT"> CAT</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/58803/snails-and-fish-as-pollution-biomarkers-in-lake-manzala-and-laboratory-c-laboratory-exposed-snails-to-chemical-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58803.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> Snails and Fish as Pollution Biomarkers in Lake Manzala and Laboratory B: Lake Manzala Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20M.%20M.%20El-Khayat">Hanaa M.

All fish samples showed a significant increase in levels of alkaline phosphatase (ALP), creatinine and glutathione-S-transferase (GST); only Dakahlya samples showed a significant increase (p<0.01) in aspartate aminotransferase (AST) level and most Dakahlya and Damietta samples showed reversed albumin and globulin ratio and a significant increase in γ-glutamyltransferase (GGT) level. Port-Said and Damietta samples showed a significant decrease of hemoglobin (Hb) while Dakahlya samples showed a significant decrease in white blood cell (WBC) count. Histopathological investigation for different fish organs showed that Port-Said and Dakahlya samples were more altered than Damietta. The muscle and gill followed by intestine were the most affected organs. The muscle sections showed severe edema, neoplasia, necrotic change, fat vacuoles and splitting of muscle fiber. The gill sections showed dilated blood vessels of the filaments, curling of gill lamellae, severe hyperplasia, edema and blood vessels congestion of filaments. The intestine sections revealed degeneration, atrophy, dilation in blood vessels and necrotic changes in sub-mucosa and mucosa with edema in between. The recorded significant alterations, in most of the physiological and histological parameters in <em>O. niloticus</em> samples from Lake Manzala, were alarming for water pollution impacts on lake fish community, which constitutes the main diet and the main source of income for the people inhabiting these areas, and were threatening their public health and economy. Also, results evaluate the use of <em>O. niloticus</em> fish as important bio-indicator for their habitat stressors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lake%20Manzala" title="Lake Manzala">Lake Manzala</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20niloticus%20fish" title=" Oreochromis niloticus fish"> Oreochromis niloticus fish</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pollution" title=" water pollution"> water pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological" title=" physiological"> physiological</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20and%20histopathological%20parameters" title=" hematological and histopathological parameters"> hematological and histopathological parameters</a> </p> <a href="https://publications.waset.org/abstracts/54438/snails-and-fish-as-pollution-biomarkers-in-lake-manzala-and-laboratory-b-lake-manzala-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54438.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">312</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">98</span> Design Data Sorter Circuit Using Insertion Sorting Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Abugharsa">Hoda Abugharsa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we propose to design a sorter circuit using insertion sorting algorithm.

Such models combine different approaches for enhanced security and respecting workflow privacy. Although modern enterprises seek conformance to workflow constraints to ensure correctness of their work, these constraints pose a threat to security, because these constraints can be good seeds for attacking privacy even in secure models. This paper introduces a comprehensive Workflow Delegation Model (WFDM) that utilizes provenance and workflow constraints to prevent malicious delegate from attacking workflow privacy as well as extending the delegation functionalities.

Besides, the synthesis of Ni/Cr-MOF in the presence of Bi₂MoO₆/AC to prepare Bi₂MoO₆/AC@Ni/Cr-MOF. All the prepared composites were synthesized via a facile technique under ambient conditions to remove organosulfur compounds. The XRD, FT-IR, SEM, and BET techniques were used to characterize the prepared composites. The desulfurization performance of real gas oil by Bi₂MoO₆/AC, Ni/Cr-MOF, and Bi₂MoO₆/AC@Ni/Cr-MOF was investigated at different adsorbent doses and contact times. Bi₂MoO₆/AC@Ni/Cr-MOF shows the highest desulfurization performance, with removal efficiency reached to 80% at optimum conditions for a contact time of 4 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desulfurization" title="desulfurization">desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20oil" title=" gas oil"> gas oil</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-organic%20framework" title=" metal-organic framework"> metal-organic framework</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption%20characteristics" title=" sorption characteristics"> sorption characteristics</a> </p> <a href="https://publications.waset.org/abstracts/171501/study-the-performance-of-metal-organic-framework-in-adsorptive-desulfurization-for-gas-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171501.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">80</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">87</span> Improved FP-Growth Algorithm with Multiple Minimum Supports Using Maximum Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elsayeda%20M.%20Elgaml">Elsayeda M.

The experimental results show that the rule mining from the proposed algorithm are interesting and our algorithm achieved better performance than other algorithms without scarifying the accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title="association rules">association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=FP-growth" title=" FP-growth"> FP-growth</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20minimum%20supports" title=" multiple minimum supports"> multiple minimum supports</a>, <a href="https://publications.waset.org/abstracts/search?q=Weka%20tool" title=" Weka tool"> Weka tool</a> </p> <a href="https://publications.waset.org/abstracts/28521/improved-fp-growth-algorithm-with-multiple-minimum-supports-using-maximum-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28521.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">485</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">86</span> Electronic Tongue as an Innovative Non-Destructive Tool for the Quality Monitoring of Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Ghasemi-Varnamkhasti">Mahdi Ghasemi-Varnamkhasti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Mohammad-Razdari"> Ayat Mohammad-Razdari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedeh-Hoda%20Yoosefian"> Seyedeh-Hoda Yoosefian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taste is an important sensory property governing acceptance of products for administration through mouth. The advent of artificial sensorial systems as non-destructive tools able to mimic chemical senses such as those known as electronic tongue (ET) has open a variety of practical applications and new possibilities in many fields where the presence of taste is the phenomenon under control. In recent years, electronic tongue technology opened the possibility to exploit information on taste attributes of fruits providing real time information about quality and ripeness. Electronic tongue systems have received considerable attention in the field of sensor technology during the last two decade because of numerous applications in diverse fields of applied sciences. This paper deals with some facets of this technology in the quality monitoring of fruits along with more recent its applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fruit" title="fruit">fruit</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20tongue" title=" electronic tongue"> electronic tongue</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive" title=" non-destructive"> non-destructive</a>, <a href="https://publications.waset.org/abstracts/search?q=taste%20machine" title=" taste machine"> taste machine</a>, <a href="https://publications.waset.org/abstracts/search?q=horticultural" title=" horticultural"> horticultural</a> </p> <a href="https://publications.waset.org/abstracts/54390/electronic-tongue-as-an-innovative-non-destructive-tool-for-the-quality-monitoring-of-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54390.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">256</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">85</span> The Effects of Modern Materials on the Moisture Resistance Performance of Architectural Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leyli%20Hashemi%20Rafsanjani">Leyli Hashemi Rafsanjani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Mortazavi%20Alavi"> Hoda Mortazavi Alavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirhossein%20Habibzadeh"> Amirhossein Habibzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At present, the atmospheric and environmental factors impose massive damages to buildings. Thus, to reduce these damages, researchers pay more attention on qualitative and quantitative characteristic of buildings materials. Condensation is one of the problems in Contemporary Sustecture Design. It could cause serious damages to the frontage, interior and structural elements of buildings. As a result, taking preventative steps to avoid condensation from occurring in buildings will help prevent avoidable and costly problems in the future. Hence, the aim of this paper is to answer the question: “Does the use of advanced materials cause the reduction of condensation formed on the walls?" In response to those flaws, this paper considered similar articles and selected 20 buildings randomly from contemporary architecture of developing countries which have been built in recent decade from 2002 to 2012, to find out the mutual relation between the usage of advanced materials and level of condensation damages. This consideration shows that by using advanced materials, we will have fewer damages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condensation" title="condensation">condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20materials" title=" advanced materials"> advanced materials</a>, <a href="https://publications.waset.org/abstracts/search?q=contemporary%20sustecture" title=" contemporary sustecture"> contemporary sustecture</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture" title=" moisture"> moisture</a> </p> <a href="https://publications.waset.org/abstracts/53472/the-effects-of-modern-materials-on-the-moisture-resistance-performance-of-architectural-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53472.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">322</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">84</span> Design and Facile Synthesis of New Amino Acid Derivatives with Anti-Tumor and Antimicrobial Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Sabry%20Othman">Hoda Sabry Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Randa%20Helmy%20Swellem"> Randa Helmy Swellem</a>, <a href="https://publications.waset.org/abstracts/search?q=Galal%20Abd%20El-Moein%20Nawwar"> Galal Abd El-Moein Nawwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> N-cyanoacetyl glycine is a reactive polyfunctional precursor for synthesis of new difficult accessible compounds including pyridones, thiazolopyridine and others.

In fact, the crop requires mild to cool winters with a chilling accumulation from November to February with average temperatures varying between two groups of accumulated chilling hours (h1) of less than 7.2 °C (C1) and other group (h2) of less than 10 °C (C2) for flower bud differentiation. This work aims at studying the impact of chilling accumulation hours on the fruit yield of olive trees in Borg El Arab City, Alexandria Governorate, Egypt as a case study. Trees were aged around 7 years in 2010 and were exposed to chilling accumulation hours of h1, which was average of 280 hours under C1, and average h2 was around 150 hours under C2 the resulted fruit yield was around 0.5 kg/tree. On the hand, trees were aged around 7 years at 2016 showed that when average of h1 was around 390 hours under C1 and average h2 was around 220 hours under C2 then fruit yield was around 10 kg/tree.

Inclined load caring capacity and pile stiffness, as well as lateral deformation profiles along with the pile, were presented. The global, vertical, and horizontal load displacements, as well as the deformation profiles along with the pile and the pile stiffness, are significantly affected by α. Whereas P-Y curves of the pile are independent of α., also the slenderness ratios are markedly affecting the behavior of the pile. In addition, there was a noticeable effect of the horizontal component on the vertical behavior of the pile, whereas there was no influence of the presence of vertical load on the horizontal behavior of the pile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20foundations" title="deep foundations">deep foundations</a>, <a href="https://publications.waset.org/abstracts/search?q=piles" title=" piles"> piles</a>, <a href="https://publications.waset.org/abstracts/search?q=inclined%20load" title=" inclined load"> inclined load</a>, <a href="https://publications.waset.org/abstracts/search?q=pile%20deformations" title=" pile deformations"> pile deformations</a> </p> <a href="https://publications.waset.org/abstracts/145253/behavior-of-a-vertical-pile-under-the-effect-of-an-inclined-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145253.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">172</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">81</span> Social Media as an Interactive Learning Tool Applied to Faculty of Tourism and Hotels, Fayoum University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islam%20Elsayed%20Hussein">Islam Elsayed Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to discover the impact of students’ attitude towards social media and the skills required to adopt social media as a university e-learning (2.0) platform.

Three problems, commonly associated with previous approaches, are alleviated. These problems arise due to impose assumptions on the secondary structural of premiRNA, imbalance between the numbers of the laboratory checked miRNAs and the pseudo-hairpins, and finally using a training data set that does not consider all the varieties of samples in different species. We aggregate the predicted outputs of three well-known SVM classifiers; namely, Triplet-SVM, Virgo and Mirident, weighted by their variant features without any structural assumptions. An additional SVM layer is used in aggregating the final output. The proposed approach is trained and then tested with balanced data sets. The results of the proposed approach outperform the three base classifiers. Improved values for the metrics of 88.88% f-score, 92.73% accuracy, 90.64% precision, 96.64% specificity, 87.2% sensitivity, and the area under the ROC curve is 0.91 are achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MiRNAs" title="MiRNAs">MiRNAs</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM%20classification" title=" SVM classification"> SVM classification</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble%20algorithm" title=" ensemble algorithm"> ensemble algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=assumption%20problem" title=" assumption problem"> assumption problem</a>, <a href="https://publications.waset.org/abstracts/search?q=imbalance%20data" title=" imbalance data"> imbalance data</a> </p> <a href="https://publications.waset.org/abstracts/32331/ensemble-based-svm-classification-approach-for-mirna-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32331.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">349</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">75</span> Influence of Surfactant on Supercooling Degree of Aqueous Titania Nanofluids in Energy Storage Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Aslani">Hoda Aslani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Moghiman"> Mohammad Moghiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Aslani"> Mohammad Aslani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the demand to reduce global warming potential and importance of solidification in various applications, there is an increasing interest in energy storage systems to find the efficient phase change materials. Therefore, this paper presents an experimental study and comparison on the potential of titania nanofluids with and without surfactant for cooling energy storage systems. A designed cooling generation device based on compression refrigeration cycle is used to explore nanofluids solidification characteristics. In this work, titania nanoparticles of 0.01, 0.02 and 0.04 wt.% are dispersed in deionized water as base fluid. Measurement of phase change parameters of nanofluids illustrates that the addition of polyvinylpyrrolidone (PVP) as surfactant to titania nanofluids advances the onset nucleation time and leads to lower solidification time. Also, the experimental results show that only adding 0.02 wt.% titania nanoparticles, especially in the case of nanofluids with a surfactant, can evidently reduce the supercooling degree by nearly 70%. Hence, it is concluded that there is a great energy saving potential in the energy storage systems using titania nanofluid with PVP. <p class="card-text"><strong>Keywords:</strong> <a
