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. In addition, we argue the need for exploiting workflow constraints to improve workflow security models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=workflow%20delegation%20models" title="workflow delegation models">workflow delegation models</a>, <a href="https://publications.waset.org/abstracts/search?q=secure%20workflow" title=" secure workflow"> secure workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20privacy" title=" workflow privacy"> workflow privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20provenance" title=" workflow provenance"> workflow provenance</a> </p> <a href="https://publications.waset.org/abstracts/47106/preserving-privacy-in-workflow-delegation-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47106.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">332</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">1645</span> Effect of Chilling Accumulation on Fruit Yield of Olive Trees in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20H.%20El-Sheikh">Mohamed H.

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. Increasing of fruit yield proved chilling accumulation effect on olive trees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chilling%20accumulation" title="chilling accumulation">chilling accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20yield" title=" fruit yield"> fruit yield</a>, <a href="https://publications.waset.org/abstracts/search?q=Olea%20europaea" title=" Olea europaea"> Olea europaea</a>, <a href="https://publications.waset.org/abstracts/search?q=olive" title=" olive"> olive</a> </p> <a href="https://publications.waset.org/abstracts/63113/effect-of-chilling-accumulation-on-fruit-yield-of-olive-trees-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63113.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">292</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">1644</span> Recommender System Based on Mining Graph Databases for Data-Intensive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Gamal">Mostafa Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20K.%20Mohamed"> Hoda K.

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">1643</span> Towards Reliable Mobile Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Darwish">Khaled Darwish</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam%20El%20Madahh"> Islam El Madahh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Mohamed"> Hoda Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadia%20El%20Hennawy"> Hadia El Hennawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing has been one of the fastest growing parts in IT industry mainly in the context of the future of the web where computing, communication, and storage services are main services provided for Internet users.

Location recommendation is one of the highly demanded location-aware applications uniquely with the wide accessibility of social network applications that are location-aware including Facebook check-ins, Foursquare, and others. In this paper, we aim to present a new methodology for location recommendation. The proposed approach coordinates customary spatial traits alongside other essential components including shortest distance, and user interests. We also present another idea namely, <em>"activity trajectory"</em> that represents trajectory that fulfills the set of activities that the user is intrigued to do. The approach dispatched acquaints the related distance value to select trajectory(ies) with minimum cost value (distance) and spatial-area to prune unneeded directions. The proposed calculation utilizes the idea of movement direction to prescribe most comparable N-trajectory(ies) that matches the client's required action design with least voyaging separation. To upgrade the execution of the proposed approach, parallel handling is applied through the employment of a MapReduce based approach. Experiments taking into account genuine information sets were built up and tested for assessing the proposed approach. The exhibited tests indicate how the proposed approach beets different strategies giving better precision and run time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=location%20based%20recommendation" title="location based recommendation">location based recommendation</a>, <a href="https://publications.waset.org/abstracts/search?q=map-reduce" title=" map-reduce"> map-reduce</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20system" title=" recommendation system"> recommendation system</a>, <a href="https://publications.waset.org/abstracts/search?q=trajectory%20search" title=" trajectory search"> trajectory search</a> </p> <a href="https://publications.waset.org/abstracts/56546/an-activity-based-trajectory-search-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56546.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">223</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">1641</span> Classification of Attacks Over Cloud Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Abouelmehdi">Karim Abouelmehdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Loubna%20Dali"> Loubna Dali</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmoutaoukkil%20Abdelmajid"> Elmoutaoukkil Abdelmajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Elsayed"> Hoda Elsayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Eladnani%20Fatiha"> Eladnani Fatiha</a>, <a href="https://publications.waset.org/abstracts/search?q=Benihssane%20Abderahim"> Benihssane Abderahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The security of cloud services is the concern of cloud service providers.

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">1638</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">1637</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

On the basis of aptitude to degrade the crude oil and DCPIP assay, two fungal isolates were selected amongst 15 oil degrading strains. Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54 %) and Penicillium commune (48 %) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has the capability of degradation and can be utilized for cleaning the Saudi Arabian environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20%20strains" title="fungal strains">fungal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/36036/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36036.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">522</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">1636</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.

Schizophrenia is a neurodevelopmental and progressive neurodegenerative disease, for which there are no validated biomarkers. Corneal confocal microscopy (CCM) is a non-invasive ophthalmic imaging biomarker that can be used to detect neuronal abnormalities in neuropsychiatric syndromes. Methods:- Patients with schizophrenia (DSM-V criteria) without other causes of peripheral neuropathy and healthy controls underwent CCM, vibration perception threshold (VPT) and sudomotor function testing. The diagnostic accuracy of CCM in distinguishing patients from controls was assessed using the area under the curve (AUC) of the Receiver Operating Characterstics (ROC) curve. Findings:- Participants with schizophrenia (n=17) and controls (n=38) with comparable age (35.7±8.5 vs 35.6±12.2, P=0.96) were recruited. Patients with schizophrenia had significantly higher body weight (93.9±25.5 vs 77.1±10.1, P=0.02), lower Low Density Lipoproteins (2.6±1.0 vs 3.4±0.7, P=0.02), but comparable systolic and diastolic blood pressure, HbA1c, total cholesterol, triglycerides and High Density Lipoproteins were comparable with control participants. Patients with schizophrenia had significantly lower corneal nerve fiber density (CNFD, fibers/mm2) (23.5±7.8 vs 35.6±6.5, p<0.0001), branch density (CNBD, branches/mm2) (34.4±26.9 vs 98.1±30.6, p<0.0001), and fiber length (CNFL, mm/mm2) (14.3±4.7 vs 24.2±3.9, p<0.0001) but no difference in VPT (6.1±3.1 vs 4.5±2.8, p=0.12) and electrochemical skin conductance (61.0±24.0 vs 68.9±12.3, p=0.23) compared with controls. The diagnostic accuracy of CNFD, CNBD and CNFL to distinguish patients with schizophrenia from healthy controls were, according to the AUC, (95% CI): 87.0% (76.8-98.2), 93.2% (84.2-102.3), 93.2% (84.4-102.1), respectively. Conclusion:- In conclusion, CCM can be used to help identify neuronal changes and has a high diagnostic accuracy to distinguish subjects with schizophrenia from healthy controls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/139523/corneal-confocal-microscopy-as-a-surrogate-marker-of-neuronal-pathology-in-schizophrenia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139523.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">275</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">1627</span> Modelling of Pervaporation Separation of Butanol from Aqueous Solutions Using Polydimethylsiloxane Mixed Matrix Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arian%20Ebneyamini">Arian Ebneyamini</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Azimi"> Hoda Azimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jules%20Thibaults"> Jules Thibaults</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20Handan%20Tezel"> F.

After the injection time about 15 to 20 minutes, the patient should eat a fatty meal and chocolate for the good excretion of the gall bladder, to evaluate the performance and regional wall motion of the left ventricle (LV). The results showed that the body mass index percentage in this sample was in range of 43.05 to 61.05. The number of patients who were catheter candidates were 56 with 43% and the patients that were not candidate to cathode were 74 patients with 57% of all patients. For the group of patients where type of ischemia was assessed, 29.5% of patients had reversible posterior and inferior wall, 15.1% of patients had fixed large from apex to base, 9.6% of patients had mild basal inferior wall, 4.8 % of patients had mild anterior wall, 6.2% of patients had antro-septal and 34.9% of patients had moderate ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myocardial%20ischemia" title="myocardial ischemia">myocardial ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20scintigraphy" title=" myocardial scintigraphy"> myocardial scintigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=contrast%20ventriculography" title=" contrast ventriculography"> contrast ventriculography</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20obstruction" title=" coronary artery obstruction"> coronary artery obstruction</a> </p> <a href="https://publications.waset.org/abstracts/13957/characterization-of-coronary-artery-obstruction-and-related-findings-in-ischemic-heart-patients-using-cardiac-scintigraphy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13957.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">585</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">1624</span> Effect of Papaverine on Neurospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Shehab-Eldeen">Noura Shehab-Eldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elsherbeeny"> Mohamed Elsherbeeny</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Elmetwally"> Hossam Elmetwally</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salama"> Mohamed Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Lotfy"> Ahmed Lotfy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elgamal"> Mohamed Elgamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Sheashaa"> Hussein Sheashaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sobh"> Mohamed Sobh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mitochondrial toxins including papaverine may be implicated in the etiology and pathogenesis of Parkinson's disease. The aim was to detect the effect of papaverine on the proliferation and viability of neural stem cells. Rat neural progenitor cells were isolated from embryos (E14) brains. The dispersed tissues were allowed to settle, then, The supernatant was centrifuged at 1,000 g for 5 min. The pellet was placed in Hank’s solution cultured as free-floating neurospheres Dulbecco’s modified Eagle medium (DMEM) and Hams F12 (3:1) supplemented with B27 (Invitrogen GmBH, Karlsruhe, Germany), 20 ng/mL epidermal growth factor (EGF; Biosource, Karlsruhe, Germany), 20 ng/mL recombinant human fibroblast growth factor (rhFGF; R&D Systems, Wiesbaden-Nordenstadt, Germany), and penicillin and streptomycin (1:100; Invitrogen) at 37°C with 7.5% CO2 . Differentiation was initiated by growth factor withdrawal and plating onto a poly-d-lysine/ laminin matrix. The neurospheres were fed every 2-3 days by replacing 50% of the culture media with fresh media. The culture suspension was transferred to a dish containing 16 wells. The wells were divided as follows: 4 wells received no papaverine (control), 4 wells 1 u, 4 wells 5 u and 4 wells 10 u of papaverine solution. In the next 2 weeks, photography (0,4,5,11days) and viability test were done. The photographs were analysed. Results : papaverine didn't affect proliferation of neurospheres, while it affected viability compared to control , this was dose related. Conclusion: This indicates the harmful effect of papaverine suggesting it to be a candidate neurotoxin causing Parkinsonism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurospheres" title="neurospheres">neurospheres</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20stem%20cells" title=" neural stem cells"> neural stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=papaverine" title=" papaverine"> papaverine</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinsonism" title=" Parkinsonism"> Parkinsonism</a> </p> <a href="https://publications.waset.org/abstracts/14864/effect-of-papaverine-on-neurospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14864.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">660</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">1623</span> Improved Skin Detection Using Colour Space and Texture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Medjram%20Sofiane">Medjram Sofiane</a>, <a href="https://publications.waset.org/abstracts/search?q=Babahenini%20Mohamed%20Chaouki"> Babahenini Mohamed Chaouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benali%20Yamina"> Mohamed Benali Yamina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skin detection is an important task for computer vision systems.

These results are the basis of our work which led to the calculation of the transverse reinforcement of the nodes of the structure in question. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beam%E2%80%93column%20joints" title="beam–column joints">beam–column joints</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=shearing%20force" title=" shearing force"> shearing force</a>, <a href="https://publications.waset.org/abstracts/search?q=damaged%20joint" title=" damaged joint"> damaged joint</a> </p> <a href="https://publications.waset.org/abstracts/16216/behavior-of-beam-column-nodes-reinforced-concrete-in-earthquake-zones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16216.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">550</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">1619</span> HelpMeBreathe: A Web-Based System for Asthma Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alia%20Al%20Rayssi">Alia Al Rayssi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahra%20Al%20Marar"> Mahra Al Marar</a>, <a href="https://publications.waset.org/abstracts/search?q=Alyazia%20Alkhaili"> Alyazia Alkhaili</a>, <a href="https://publications.waset.org/abstracts/search?q=Reem%20Al%20Dhaheri"> Reem Al Dhaheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Shayma%20Alkobaisi"> Shayma Alkobaisi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Amer"> Hoda Amer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present in this paper a web-based system called “<em>HelpMeBreathe</em>” for managing asthma. The proposed system provides analytical tools, which allow better understanding of environmental triggers of asthma, hence better support of data-driven decision making. The developed system provides warning messages to a specific asthma patient if the weather in his/her area might cause any difficulty in breathing or could trigger an asthma attack. <em>HelpMeBreathe</em> collects, stores, and analyzes individuals’ moving trajectories and health conditions as well as environmental data. It then processes and displays the patients’ data through an analytical tool that leads to an effective decision making by physicians and other decision makers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asthma" title="asthma">asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20triggers" title=" environmental triggers"> environmental triggers</a>, <a href="https://publications.waset.org/abstracts/search?q=map%20interface" title=" map interface"> map interface</a>, <a href="https://publications.waset.org/abstracts/search?q=web-based%20systems" title=" web-based systems"> web-based systems</a> </p> <a href="https://publications.waset.org/abstracts/67708/helpmebreathe-a-web-based-system-for-asthma-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67708.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">294</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">1618</span> Contribution to the Analytical Study of the Stability of a DC-DC Converter (Boost) Used for MPPT Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amarouayache">Mohamed Amarouayache</a>, <a href="https://publications.waset.org/abstracts/search?q=Badia%20Amrouche"> Badia Amrouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Gharbi%20Akila"> Gharbi Akila</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukadoume%20Mohamed"> Boukadoume Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is devoted to the modeling of DC-DC converter (boost) used for MPPT applications to set conditions of stability.

A mathematical relationship between the duty cycle and the voltage of the panel has been set up. With this relationship we specify the conditions of the stability in closed-loop depending on the system parameters (the elements of storage capacity and inductance, PWM control). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MPPT" title="MPPT">MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM" title=" PWM"> PWM</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=criterion%20of%20Routh" title=" criterion of Routh"> criterion of Routh</a>, <a href="https://publications.waset.org/abstracts/search?q=average%20small%20signal%20model" title=" average small signal model "> average small signal model </a> </p> <a href="https://publications.waset.org/abstracts/2045/contribution-to-the-analytical-study-of-the-stability-of-a-dc-dc-converter-boost-used-for-mppt-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2045.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1617</span> Schiff Bases of Isatin and Admantane-1-Carbohydrazide: Synthesis, Characterization, and Anticonvulsant Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hind%20O.%20Osman">Hind O.

In the present study, the molecular hybridization tool was adopted to obtain six Schiﬀ bases of isatin and adamantane-1-carbohydrazide (18–23). Then, their anticonvulsant activity was evaluated using a pentylenetetrazole- (PTZ-) induced seizure model using phenobarbitone as a positive control. Our ﬁndings showed that compounds 18–23 provided signiﬁcant protection against PTZ-induced seizure, and maximum activities were associated with compound 23. Moreover, all investigated compounds increased the latency of induced convulsion and reduced the duration of epilepsy, with compound 23 being the best. Interestingly, most of the synthesized molecules showed a reduction in neurological symptoms and severity of the seizure. Molecular docking studies suggest GABA-A receptor as a potential target, and in silico ADME screening revealed that the pharmaceutical properties of compound 23 are within the speciﬁed limit. Thus, compound 23 was identified as a promising candidate that warrants further drug discovery processes. <p class="card-text"><strong>Keywords:</strong> <a
