Platinating agents induce DNA damage which activate Mre11 nuclease directed DNA damage signalling and response (DDR). Upregulation of DDR may promote chemotherapy resistance. Here we have comprehensively evaluated Mre11 in epithelial ovarian cancers. In clinical cohort that received platinum- based chemotherapy (n=331), Mre11 protein overexpression was associated with aggressive phenotype and poor progression free survival (PFS) (p=0.002). In the ovarian cancer genome atlas (TCGA) cohort (n=498), Mre11 gene amplification was observed in a subset of serous tumours (5%) which correlated highly with Mre11 mRNA levels (p<0.0001). Altered Mre11 levels was linked with genome wide alterations that can influence platinum sensitivity. At the transcriptomic level (n=1259), Mre11 overexpression was associated with poor PFS (p=0.003). ROC analysis showed an area under the curve (AUC) of 0.642 for response to platinum-based chemotherapy. Pre-clinically, Mre11 depletion by gene knock down or blockade by small molecule inhibitor (Mirin) reversed platinum resistance in ovarian cancer cells and in 3D spheroid models. Importantly, Mre11 inhibition was synthetically lethal in platinum sensitive XRCC1 deficient ovarian cancer cells and 3D-spheroids. Selective cytotoxicity was associated with DNA double strand break (DSB) accumulation, S-phase cell cycle arrest and increased apoptosis. We conclude that pharmaceutical development of Mre11 inhibitors is a viable clinical strategy for platinum sensitization and synthetic lethality in ovarian cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MRE11%3B%20XRCC1" title="MRE11; XRCC1">MRE11; XRCC1</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20cancer" title=" ovarian cancer"> ovarian cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=platinum%20sensitization" title=" platinum sensitization"> platinum sensitization</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20lethality" title=" synthetic lethality"> synthetic lethality</a> </p> <a href="https://publications.waset.org/abstracts/151440/targeting-mre11-nuclease-overcomes-platinum-resistance-and-induces-synthetic-lethality-in-platinum-sensitive-xrcc1-deficient-epithelial-ovarian-cancers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151440.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">129</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">58</span> Computer Software for Calculating Electron Mobility of Semiconductors Compounds; Case Study for N-Gan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20A.%20Ahmed">Emad A.

In present study, germinated and terminated soya flour blends were prepared and supplemented in bread in variable proportions (10 % and 20 % of each) to check its impact on quality and sensory attributes of bread. The results showed that there was a significant increase in protein, ash and crude fat contents due to increase in the level of germinated and ungerminated soya flour. However, the moisture and crude fiber contents of composite flours containing germinated and ungerminated soya flour decreased with increased level of supplementation. Mean values for physical analysis (loaf volume, specific volume, weight loss and force for texture) were significantly higher in breads prepared with germinated soya bean flour.The scores assigned to sensory parameters of breads like volume, color of crust, symmetry, color of crumb, texture, taste and aroma decreased significantly by increasing the level of germinated and ungerminated soya flour in wheat flour while color of crust and taste slightly improved. The scores given to overall acceptability of bread prepared from composite flour supplemented with 10 % germinated soya flour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20bread" title="composite bread">composite bread</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20energy%20malnutrition" title=" protein energy malnutrition"> protein energy malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=supplementation" title=" supplementation"> supplementation</a>, <a href="https://publications.waset.org/abstracts/search?q=amino%20acid%20profile" title=" amino acid profile"> amino acid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20legumes" title=" grain legumes"> grain legumes</a> </p> <a href="https://publications.waset.org/abstracts/31768/comparative-study-of-bread-prepared-with-and-without-germinated-soyabean-glycine-max-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31768.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">430</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">56</span> Approximate Solution to Non-Linear Schrödinger Equation with Harmonic Oscillator by Elzaki Decomposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20K.%20Jaradat">Emad K.

Two biodegradable polymers, polycaprolactone and starch, environmental friendly and obtained from renewable, easily available raw materials, have been chosen. Fatty hydrazide, synthesized from palm oil, has been used as a surfactant to modify montmorillonite (natural clay) for preparation of polycaprolactone/starch nanocomposite. X-ray diffraction and transmission electron microscopy were used to characterize nanocomposite formation. Compatibility of the blend was improved by adding 3% weight modified clay. Higher biodegradability and thermal stability of nanocomopeite were also observed compared to those of the polycaprolactone/starch blend.

The basic idea behind our technique is to measure the interquartile range or the spread of the 3D model vertices. The algorithm starts by converting all the vertices to spherical coordinate followed by partitioning them into small groups. The proposed algorithm is slightly altering the interquartile range distribution of the small groups based on predefined watermark. The experimental results on several 3D meshes prove perceptual invisibility and the robustness of the proposed technique against the most common attacks including compression, noise, smoothing, scaling, rotation as well as combinations of these attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=watermarking" title="watermarking">watermarking</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20models" title=" three-dimensional models"> three-dimensional models</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptual%20invisibility" title=" perceptual invisibility"> perceptual invisibility</a>, <a href="https://publications.waset.org/abstracts/search?q=interquartile%20range" title=" interquartile range"> interquartile range</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20attacks" title=" 3D attacks"> 3D attacks</a> </p> <a href="https://publications.waset.org/abstracts/15946/a-blind-three-dimensional-meshes-watermarking-using-the-interquartile-range" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15946.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">474</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">53</span> Vehicle to Vehicle Communication: Collision Avoidance Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad">Ahmed Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Salah"> Ahmed Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Magdy"> Abdelrahman Magdy</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Rashid"> Omar Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Adel"> Mohammed Adel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper discusses vehicle-to-vehicle technology as an important application of linear algebra.

This particular advantage is of paramount importance when it comes to structures producing lift at high angles of attack. This characteristic of the technology makes it ideal for horizontal stabilizers and selecting the same as the subject of study to identify and exploit the advantage highlighted by researchers on airfoils, this project aims in establishing a foundation for the application of the bio-mimicked technology on an existing aircraft. Using a baseline and 2 tubercle configuration integrated models, the project targets to achieve the twin aim of highlighting the possibility and merits over the base model and also choosing the right configuration in providing the best characteristic suitable for high angles of attack. To facilitate this study, the required models are generated using Solidworks followed by trials in a virtual aerodynamic environment using Fluent in Ansys for resolving the project objectives. Following a structured plan, the aim is to initially identify the advantages mathematically and then selecting the optimal configuration, simulate the end configuration at angles mimicking the actual operation envelope for the particular structure. Upon simulating the baseline configuration at various angles of attack, the stall angle was determined to be 22 degrees. Thus, the tubercle configurations will be simulated and compared at 4 different angles of attacks: 0, 10, 20, and 24. Further, after providing the optimum configuration of horizontal stabilizers, this study aims at the integration of aircraft structure so that the results better imply the end deliverables of real life application. This draws the project scope closer at this point into longitudinal static stability considerations and improvements in the manoeuvrability characteristics. The objective of the study is to achieve a complete overview ready for real life application with marked benefits obtainable from bio morphing of the tubercle technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20simulation" title="flow simulation">flow simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20stabilizer" title=" horizontal stabilizer"> horizontal stabilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20enhancement" title=" stability enhancement"> stability enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=tubercle" title=" tubercle"> tubercle</a> </p> <a href="https://publications.waset.org/abstracts/43647/enhancement-of-aircraft-longitudinal-stability-using-tubercles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43647.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">320</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">50</span> Mechanical Properties of a Soil Stabilized With a Portland Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad%20Ahmed">Ahmed Emad Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20El%20Abd"> Mostafa El Abd</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Wakeb"> Ahmed Wakeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Moahmmed%20Eissa"> Moahmmed Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil modification and reinforcing aims to increase soil shear strength and stiffness.

There are three main factors affecting the design of soil replacement to gain these advantages. These factors are the type of replaced soil, characteristics, and thickness. The first two factors can be easily determined by laboratory and field control. This paper emphasizes on how to determine the thickness accurately for footing under centric axial load by limit state design method. The advantages of the method are the way of determining the thickness (independent of experience) and it takes into account the replaced and original or underneath soil characteristics and reaches the goals of replaced soils economically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20of%20soil%20replacement" title="design of soil replacement">design of soil replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=LSD%20method" title=" LSD method"> LSD method</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20replacement" title=" soil replacement"> soil replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20improvement" title=" soil improvement"> soil improvement</a> </p> <a href="https://publications.waset.org/abstracts/37928/design-of-soil-replacement-under-axial-centric-load-isolated-footing-by-limit-state-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37928.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">351</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">48</span> Cryopreservation of Ring-Necked Pheasant (Phasianus colchicus) Semen for Establishing Cryobank </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rida%20Pervaiz">Rida Pervaiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Allah%20Rakha"> Bushra Allah Rakha</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sajjad%20Ansari"> Muhammad Sajjad Ansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamim%20Akhter"> Shamim Akhter</a>, <a href="https://publications.waset.org/abstracts/search?q=Kainat%20Waseem"> Kainat Waseem</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumiyyah%20Zuha"> Sumiyyah Zuha</a>, <a href="https://publications.waset.org/abstracts/search?q=Tooba%20Javed"> Tooba Javed </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ring-necked pheasant (Phasianus colchicus) belongs to order Galliformes and family Phasianidae. It has been recognized as the most hunted bird due to its attractive colorful appearance and meat. Loss of habitat and hunting pressure has caused population fluctuations in the native range. Under these circumstances, this species can be conserved by employing ex-situ in vitro conservation techniques. Captive breeding, in combination with semen cryobanking is the most appropriate option to conserve/propagate this species without deteriorating the genetic diversity. Cryopreservation protocols of adequate efficiency are necessary to establish semen cryobanking for a species. Therefore, present study was designed to devise an efficient extender for cryopreservation of ring-necked pheasant semen. For this purpose, a range of extenders (Beltsville Poultry, red fowl, Lake, EK, Tselutin Poultry and Chicken semen extenders) were evaluated for cryopreservation of ring-necked pheasant semen. Semen collected from 10 cocks, diluted in the Beltsville Poultry (BPSE), Red Fowl (RFE), Lake (LE), EK (EKE), Tselutin Poultry (TPE) and Chicken Semen (CSE) extenders and cryopreserved. Glycerol (10%) was added to semen at 4°C, equilibrated for 10 min, filled in 0.5 mL French straws, kept over liquid nitrogen vapors for 10 min, cryopreserved in LN2 and stored. Sperm motility (%), viability (%), live/dead ratio (%), plasma membrane (%) and DNA Integrity (%) were evaluated at post-dilution, post-cooling, post-equilibration and post-thawing stage of cryopreservation. Sperm motility (83.8 ± 3.1; 81.3 ± 3.8; 73.8 ± 2.4; 62.5 ± 1.4), viability (79.0 ± 1.7; 75.5 ± 1.6; 69.5 ± 2.3; 65.5 ± 2.4), live/dead ratio (80.5 ± 5.7; 77.3 ± 4.9; 76.0 ± 2.7; 68.3 ± 2.3), plasma membrane (74.5 ± 2.9; 73.8 ± 3.4; 71.3 ± 2.3; 75.0 ± 3.4) and DNA integrity (78.3 ± 1.7; 73.0 ± 1.2; 68.0 ± 2.0; 63.0 ± 2.5) at all four stages of cryopreservation were recorded higher (P < 0.05) in red fowl extender compared to all experimental extenders. It is concluded that red fowl extender is the best extender for cryopreservation of ring-necked pheasant semen and can be used in establishing cryobank for ex situ conservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ring-necked%20pheasant%3B%20extenders%3B%20cryopreservation%3B%20semen%20quality%3B%20DNA%20integrity" title="ring-necked pheasant; extenders; cryopreservation; semen quality; DNA integrity ">ring-necked pheasant; extenders; cryopreservation; semen quality; DNA integrity </a> </p> <a href="https://publications.waset.org/abstracts/112993/cryopreservation-of-ring-necked-pheasant-phasianus-colchicus-semen-for-establishing-cryobank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112993.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">140</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">47</span> An Automatic Feature Extraction Technique for 2D Punch Shapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awais%20Ahmad%20Khan">Awais Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Abouel%20Nasr"> Emad Abouel Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20M.%20A.%20Hussein"> H.

Forensic entomology is a neglected field in Pakistan. Insects collected from the crime scene should be handled by forensic entomologists who are currently virtually non-existent in Pakistan. Correct identification of insect specimen along with knowledge of their biodiversity can aid in solving many problems related to complicated forensic cases. Inadequate morphological identification and insufficient thermal biological studies limit the entomological utility in Forensic Medicine. Recently molecular identification of entomological evidence has gained attention globally. DNA barcoding is the latest and established method for species identification. Only proper identification can provide a precise estimation of postmortem intervals. Arthropods are known to be the first tourists scavenging on decomposing dead matter. The objective of the proposed study was to identify species by molecular techniques and analyze their phylogenetic importance with barcoded necrophagous insect species of early succession on human cadavers. Based upon this identification, the study outcomes will be the utilization of established DNA bar codes to identify carrion feeding insect species for concordant estimation of post mortem interval. A molecular identification method involving sequencing of a 658bp ‘barcode’ fragment of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene from collected specimens of unknown dipteral species from cadavers of Lahore was evaluated. Nucleotide sequence divergences were calculated using MEGA 7 and Arlequin, and a neighbor-joining phylogenetic tree was generated. Three species were identified, Chrysomya megacephala, Chrysomya saffranea, and Chrysomya rufifacies with low genetic diversity. The fixation index was 0.83992 that suggests a need for further studies to identify and classify forensically relevant insects in Pakistan. There is an exigency demand for further research especially when immature forms of arthropods are recovered from the crime scene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molecular%20diversity" title="molecular diversity">molecular diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20barcoding" title=" DNA barcoding"> DNA barcoding</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20identification" title=" species identification"> species identification</a>, <a href="https://publications.waset.org/abstracts/search?q=forensically%20relevant" title=" forensically relevant"> forensically relevant</a> </p> <a href="https://publications.waset.org/abstracts/114178/molecular-diversity-of-forensically-relevant-insects-from-the-cadavers-of-lahore" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114178.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">149</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">44</span> Effect of Electromagnetic Field on Capacitive Deionization Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alibi%20Kilybay">Alibi Kilybay</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Alhseinat"> Emad Alhseinat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Mustafa"> Ibrahim Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulfahim%20Arangadi"> Abdulfahim Arangadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei%20Shui"> Pei Shui</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Almarzooqi"> Faisal Almarzooqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the electromagnetic field has been used for improving the performance of the capacitive deionization process. The effect of electromagnetic fields on the efficiency of the capacitive deionization (CDI) process was investigated experimentally. The results showed that treating the feed stream of the CDI process using an electromagnetic field can enhance the electrosorption capacity from 20% up to 70%. The effect of the degree of time of exposure, concentration, and type of ions have been examined. The electromagnetic field enhanced the salt adsorption capacity (SAC) of the Ca²⁺ ions by 70%, while the SAC enhanced 20% to the Na⁺ ions. It is hypnotized that the electrometric field affects the hydration shell around the ions and thus reduces their effective size and enhances the mass transfer. This reduction in ion effective size and increase in mass transfer enhanced the electrosorption capacity and kinetics of the CDI process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitive%20deionization" title="capacitive deionization">capacitive deionization</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20treatment" title=" electromagnetic treatment"> electromagnetic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment"> water treatment</a> </p> <a href="https://publications.waset.org/abstracts/134804/effect-of-electromagnetic-field-on-capacitive-deionization-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134804.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">264</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">43</span> Prevalence and Potential Risk Factors Associated with Skin Affection in Donkeys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Z.%20Sayed-Ahmed">Mohamed Z.

Across sectional study was undertaken between March 2009 and February 2010 to verify the prevalence of skin affection of donkeys. A total of 1134 donkeys in northern Egypt were investigated. A questionnaire was constructed to verify the number of infected contact animals as well as the associated factors. Physical examination was carried out, and the distribution of skin lesions was recorded. Skin scraping and biopsy were obtained to perform bacteriological, mycological, and histopathological examinations. Thirty-five (3.09%) out of 1134 noticed donkeys had skin affections including mange (18/35), dermatophytosis (6/35), bacterial dermatitis (6/35) urticaria (2/35) and allergic dermatitis (3/35).

The factors affecting the (MMP) as it is proved from the literature and from the dataset are as follows: XC2-6: Intermediate composition in the oil-containing C2-6, CO2 and H2S, in mole %, XC1: Amount of methane in the oil (%),T: Temperature (°C), MwC7+: Molecular weight of C7+ (g/mol), YC2+: Mole percent of C2+ composition in injected gas (%), MwC2+: Molecular weight of C2+ in injected gas. Fuzzy Logic and Neural Networks have been used widely in prediction and classification, with relatively high accuracy, in different fields of study. It is well known that the Fuzzy Inference system can handle uncertainty within the inputs such as in our case.

However, only a few researches were done on the identity of its public space. This paper links both the architectural and the socio-political aspects of the Cairene public space and studies how they affected each other. The subject of the study is Maydan Salah al-Din, the main city square of medieval Cairo, which reveals a quite useful information, not only about the architectural identity of the Cairene public space but also about the socio-political patterns that operated within. The analytical framework is based on Lefebvre’s theory, the ‘production of space’, in which he applied 'the Hegelian dialectic' in order to understand how the social practice forms the space, and how, in turn, the space forms the social practice. This framework offers a comprehensive understanding of the identity of the Cairene public space, which does not separate architecture from the social practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectural%20identity" title="architectural identity">architectural identity</a>, <a href="https://publications.waset.org/abstracts/search?q=Cairene%20public%20space" title=" Cairene public space"> Cairene public space</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20architectural%20history" title=" Islamic architectural history"> Islamic architectural history</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20of%20space" title=" production of space"> production of space</a> </p> <a href="https://publications.waset.org/abstracts/89721/the-identity-of-the-cairene-public-space-manifestations-of-social-and-architectural-heritage-in-the-city-square-of-medieval-cairo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89721.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">363</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">40</span> Optimization of Passive Vibration Damping of Space Structures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20Askar">Emad Askar</a>, <a href="https://publications.waset.org/abstracts/search?q=Eldesoky%20Elsoaly"> Eldesoky Elsoaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Kamel"> Mohamed Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Kamel"> Hisham Kamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this article is to improve the passive vibration damping of solar array (SA) used in space structures, by the effective application of numerical optimization. A case study of a SA is used for demonstration. A finite element (FE) model was created and verified by experimental testing. Optimization was then conducted by implementing the FE model with the genetic algorithm, to find the optimal placement of aluminum circular patches, to suppress the first two bending mode shapes. The results were verified using experimental testing. Finally, a parametric study was conducted using the FE model where patch locations, material type, and shape were varied one at a time, and the results were compared with the optimal ones.

The water-side Rew and the air-side Rea were at 5 x 102 and at from 1.8 x 103 to 9.7 x 103, respectively. Three cases of the tubes arrangements with various angles of attack, row angles of attack and 90° cone angles were employed at the considered Rea range. Correlation of pressure drop coefficient Pdc in terms of Rea, design parameters for the studied cases were presented. The flow pattern around the staggered wing-shaped tubes bundle were predicted by using commercial CFD FLUENT 6.3.26 software package. Results indicated that the values of Pdc were increased by increasing the angle of attack from 0° to 45°, while the opposite was true for angles of attack from 135° to 180°.

In order to deliver water from resources to the users, many procedures should be taken by the water engineers. One of the main procedures to deliver water to the community is by designing pressurizer pipe networks for water. The main aim of this work is to calculate the water demand of a small town and then design a simple water network to distribute water resources among the town with the smallest losses. Literature has been mentioned to cover the main point related to water distribution. Moreover, the methodology has introduced two approaches to solve the research problem, one by the iterative method of Hardy-cross and the other by water software Pipe Flow. The results have introduced two main designs to satisfy the same research requirements. Finally, the researchers have concluded that the use of water software provides more abilities and options for water engineers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=looping%20pipe%20networks" title="looping pipe networks">looping pipe networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hardy%20cross%20networks%20accuracy" title=" hardy cross networks accuracy"> hardy cross networks accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20error%20of%20hardy%20cross%20method" title=" relative error of hardy cross method"> relative error of hardy cross method</a> </p> <a href="https://publications.waset.org/abstracts/156922/comparison-between-hardy-cross-method-and-water-software-to-solve-a-pipe-networking-design-problem-for-a-small-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156922.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">165</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">37</span> Intelligent Earthquake Prediction System Based On Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20Amar">Emad Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Tawfik%20Khattab"> Tawfik Khattab</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zada"> Fatma Zada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predicting earthquakes is an important issue in the study of geography.

Therefore, accurate forecasting of BCI is essential for bridge rehabilitation budgeting planning. The large amount of data available in regard to bridge conditions for several years dictate utilizing traditional mathematical models as infeasible analysis methods. This research study focuses on investigating different classification models that are developed to predict the bridge condition index in the province of Ontario, Canada based on the publicly available data for 2800 bridges over a period of more than 10 years. The data preparation is a key factor to develop acceptable classification models even with the simplest one, the k-NN model. All the models were tested, compared and statistically validated via cross validation and t-test. A simple k-NN model showed reasonable results (within 0.5% relative error) when predicting the bridge condition in an incoming year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asset%20management" title="asset management">asset management</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge%20condition%20index" title=" bridge condition index"> bridge condition index</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20discovery%20in%20databases" title=" knowledge discovery in databases"> knowledge discovery in databases</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20models" title=" predictive models"> predictive models</a> </p> <a href="https://publications.waset.org/abstracts/92447/comparison-of-data-mining-models-to-predict-future-bridge-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92447.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">191</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">35</span> An Empirical Study of Factors that Impact Government E-Services Acceptance by Citizens: Case Study from UAE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20Bataineh">Emad Bataineh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Al-Mutawa"> Sara Al-Mutawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary focus of this study is to investigate and identify the perceptions of potential end users relating to factors which impact on e-services acceptance. Technology Acceptance Model (TAM) has been adopted in this study as it can be extended when technologies are introduced. This research validates the developed TAM model and evaluates the variance of the outcome variable (acceptance of e-services). Five factors were adopted as determinants of acceptance of e-services: ease of use, security, trust, web skills, and language. The study was undertaken in the General Directorate of Residency and Foreigners Affairs (GDRFA) in the UAE. A quantitative survey methodology was adopted in this study, which surveyed 466 customers who use the GDRFA e-services. The overall findings revealed that security language, web skills and support significantly affected ease of use and perceived usefulness. However, the trust doesn’t affect the ease of use. Further, ease of use significantly affects intention to use and perceived usefulness while in turn intention to use was influenced by perceived usefulness. This study offers an understanding of people’s adoption of e-government services with the help of established theories such as TAM and various factors that influence the e-government adoption with reference to UAE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-government%20portal" title="e-government portal">e-government portal</a>, <a href="https://publications.waset.org/abstracts/search?q=e-service" title=" e-service"> e-service</a>, <a href="https://publications.waset.org/abstracts/search?q=usability" title=" usability"> usability</a>, <a href="https://publications.waset.org/abstracts/search?q=TAM%20model" title=" TAM model"> TAM model</a> </p> <a href="https://publications.waset.org/abstracts/23168/an-empirical-study-of-factors-that-impact-government-e-services-acceptance-by-citizens-case-study-from-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23168.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">430</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">34</span> Choking among Infants and Young Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20M.Abdullat">Emad M.Abdullat</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20A.%20Ader-Rahman"> Hasan A.

A total of 27 cases of choking in the pediatric age group were retrieved from the reports of the autopsy cases dissected. All cases of children who died due to chocking by foreign bodies were under 11 years old. Choking by food materials constituted (44.4%) of cases under 3 years of age while choking by non-food material were less prevalent under 3 years of age and comprising 18.5% of the cases. Health care personnel and parents need to be aware that introduction of solid food, unlike exclusive breast or formula-milk feeding, can have serious consequences if occurring in inappropriate timing or consistency during early childhood physical and functional development.

Input data for QNA are the rate and variability parameters of the arrival and service times in addition to the number of servers in each facility. Patient flows mostly match real flow for a hospital in Egypt. Based on the analysis of the waiting times, two approaches are suggested for improving performance: Separating patients into service groups, and adopting different service policies for sequencing patients through hospital units. The separation of a specific group of patients, with higher performance target, to be served separately from the rest of patients requiring lower performance target, requires the same capacity while improves performance for the selected group of patients with higher target. Besides, it is shown that adopting the shortest processing time and shortest remaining processing time service policies among other tested policies would results in, respectively, 11.47% and 13.75% reduction in average waiting time relative to first come first served policy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=queueing%20network" title="queueing network">queueing network</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete-event%20simulation" title=" discrete-event simulation"> discrete-event simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20applications" title=" health applications"> health applications</a>, <a href="https://publications.waset.org/abstracts/search?q=SPT" title=" SPT"> SPT</a> </p> <a href="https://publications.waset.org/abstracts/56783/modelling-a-hospital-as-a-queueing-network-analysis-for-improving-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56783.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">187</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">32</span> Introduction of Robust Multivariate Process Capability Indices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Khalilloo">Behrooz Khalilloo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Shahriari"> Hamid Shahriari</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Roghanian"> Emad Roghanian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Process capability indices (PCIs) are important concepts of statistical quality control and measure the capability of processes and how much processes are meeting certain specifications.

Under the assumption of multivariate normality, the distribution parameters, mean vector and variance-covariance matrix must be estimated, when they are unknown. Classic estimation methods like method of moment estimation (MME) or maximum likelihood estimation (MLE) makes good estimation of the population parameters when data are not contaminated. But when outliers exist in the data, MME and MLE make weak estimators of the population parameters. So we need some estimators which have good estimation in the presence of outliers. In this work robust M-estimators for estimating these parameters are used and based on robust parameter estimators, robust process capability indices are introduced. The performances of these robust estimators in the presence of outliers and their effects on process capability indices are evaluated by real and simulated multivariate data. The results indicate that the proposed robust capability indices perform much better than the existing process capability indices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multivariate%20process%20capability%20indices" title="multivariate process capability indices">multivariate process capability indices</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20M-estimator" title=" robust M-estimator"> robust M-estimator</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier" title=" outlier"> outlier</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20quality%20control" title=" multivariate quality control"> multivariate quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20quality%20control" title=" statistical quality control"> statistical quality control</a> </p> <a href="https://publications.waset.org/abstracts/81586/introduction-of-robust-multivariate-process-capability-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81586.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">283</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">31</span> Pushover Analysis of Reinforced Concrete Beam-Column Joint Strengthening with Ultra High Performance Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulsamee%20Halahla">Abdulsamee Halahla</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Allout"> Emad Allout</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to study the behavior of exterior beam-column joints (BCJs) strengthened with ultra-high performance concrete (UHPC), in terms of the shear strength and maximum displacement using pushover analysis at the tip of the beam. A finite element (F.E) analysis was performed to study three main parameters – the level of the axial load in the column (N), the beam shear reinforcement (Av/s)B, and the effect of using UHPC. The normal concrete at the studied joint region was replaced by UHPC. The model was verified by using experimental results taken from the literature. The results showed that the UHPC contributed to the transference of the plastic hinge from the joint to the beam-column interface. In addition, the strength of the UHPC-strengthened joints was enhanced dramatically from 8% to 38% for the joints subjected to 12.8MPa and zero axial loads, respectively. Moreover, the UHPC contributed in improving the maximum deflection. This improvement amounted to 1% and 176% for the joints subjected to zero and 12.8MPa axial load, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra%20high%20performance%20concrete" title="ultra high performance concrete">ultra high performance concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20joints" title=" reinforced concrete joints"> reinforced concrete joints</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20behavior%3B%20pushover%20analysis" title=" nonlinear behavior; pushover analysis"> nonlinear behavior; pushover analysis</a> </p> <a href="https://publications.waset.org/abstracts/123132/pushover-analysis-of-reinforced-concrete-beam-column-joint-strengthening-with-ultra-high-performance-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123132.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">135</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">30</span> The Effects of Metformin And PCL-sorafenib Nanoparticles Co-treatment on MCF-7 Cell Culture Model of Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20Heydarnia">Emad Heydarnia</a>, <a href="https://publications.waset.org/abstracts/search?q=Aref%20Sepasi"> Aref Sepasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nika%20Asefi"> Nika Asefi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Khakshournia"> Sara Khakshournia</a>, <a href="https://publications.waset.org/abstracts/search?q=Javad%20Mohammadnejad"> Javad Mohammadnejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Despite breakthrough therapeutics in breast cancer, it is one of the main causes of mortality among women worldwide. Thus, drug therapies for treating breast cancer have recently been developed by scientists. Metformin and Sorafenib are well-known therapeutic in breast cancer. In the present study, we combined Sorafenib and PCL-sorafenib with metformin to improve drug absorption and promote therapeutic efficiency. Methods: The MCF-7 cells were treated with Metformin, Sorafenib, or PCL-sorafenib. The growth inhibitory effect of these drugs and cell viability were assessed using MTT and flow cytometry assays, respectively. The expression of targeted genes involved in cell proliferation, signaling, and the cell cycle was measured by Real-time PCR. Results: The results showed that MCF-7 cells treated with Metformin/Sorafenib and PCL-sorafenib/Metformin co-treatment contributed to 50% viability compared to untreated group. Moreover, PI and Annexin V staining tests showed that the cells viability for Metformin/Sorafenib and PCL-sorafenib/Metformin was 38% and 17%, respectively. Furthermore, Sorafenib/Metformin and PCL-sorafenib/Metformin leads to p53 gene expression increase by which they can increase ROS, thereby decreasing GPX4 gene expression. In addition, they affected the expression of BCL2, and BAX genes and altered the cell cycle. Conclusion: Together, the combination of PCL-sorafenib/Metformin and Sorafenib/Metformin increased Sorafenib absorption at lower doses and also leads to apoptosis and oxidative stress increases in MCF-7 cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a
