It is very common among adolescents and schoolchildren and the effects can be devastating and long-lasting. Students are most commonly bullied about physical appearance, race, gender, disability, ethnicity, religion, and sexual orientation. Appearance-targeted bullying is a form of bullying that targets an aspect of a person's appearance, which includes facial and dental features. Deviation from accepted dentofacial aesthetics leads to elevated incidences of bullying in schoolchildren. The aim of this review article is to assess the prevalence of bullying due to dentofacial characteristics and evaluate the importance of dentofacial appearance on perceived social attractiveness based on multiple studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dentofacial%20features" title="dentofacial features">dentofacial features</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title=" orthodontics"> orthodontics</a>, <a href="https://publications.waset.org/abstracts/search?q=malocclusion" title=" malocclusion"> malocclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=bullying" title=" bullying"> bullying</a> </p> <a href="https://publications.waset.org/abstracts/166879/dentofacial-targeted-bullying-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166879.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">79</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">147</span> Dental Implants in Breast Cancer Patients Receiving Bisphosphonate Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ashraf%20Talaat">Mai Ashraf Talaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The aim of this review article is to assess the success of dental implants in breast cancer patients receiving bisphosphonate therapy and to evaluate the risk of developing bisphosphonate-related osteonecrosis of the jaw following dental implant surgery. Materials and Methods: A thorough search was conducted, with no time or language restriction, using: PubMed, PubMed Central, Web of Science, and ResearchGate electronic databases. Medical Subject Headings (MeSH) terms such as “bisphosphonate”, “dental implant”, “bisphosphonate-related osteonecrosis of the jaw (BRONJ)”, “osteonecrosis”, “breast cancer, MRONJ”, and their related entry terms were used. Eligibility criteria included studies and clinical trials that evaluated the impact of bisphosphonates on dental implants. Conclusion: Breast cancer patients undergoing bisphosphonate therapy may receive dental implants. However, the risk of developing BRONJ and implant failure is high. Risk factors such as the type of BP received, the route of administration, and the length of treatment prior to surgery should be considered. More randomized controlled trials with long-term follow-ups are needed to draw more evidence-based conclusions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20implants" title="dental implants">dental implants</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=bisphosphonates" title=" bisphosphonates"> bisphosphonates</a>, <a href="https://publications.waset.org/abstracts/search?q=osteonecrosis" title=" osteonecrosis"> osteonecrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bisphosphonate-related%20osteonecrosis%20of%20the%20jaw" title=" bisphosphonate-related osteonecrosis of the jaw"> bisphosphonate-related osteonecrosis of the jaw</a> </p> <a href="https://publications.waset.org/abstracts/161989/dental-implants-in-breast-cancer-patients-receiving-bisphosphonate-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161989.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">112</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">146</span> The Relation between Vitamin C and Oral Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ashraf%20Talaat">Mai Ashraf Talaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Vitamin C (ascorbic acid) is an essential nutrient for the development and repair of all body tissues. It can be obtained from a healthy diet or through supplementation. Due to its importance, vitamin C has become a mainstay in the treatment and prevention of many diseases and in maintaining immune, skin, bone and overall health. This review article aims to discuss the studies and case reports conducted to evaluate the effect of Vitamin C on oral health and the recent advances in oral medicine that involve the use of vitamin C. Data/Sources: The review was conducted for clinical studies, case reports and published literature in the English language that addresses this topic. An extensive search in the electronic databases of PubMed, PubMed Central, Web of Science, National Library of Medicine and ResearchGate was performed. Conclusion: Vitamin C is thought to treat periodontal diseases and gingival enlargement. It also affects biofilm formation and therefore, it helps in reducing caries incidence. Recently, vitamin C mesotherapy has been used to treat inflamed gingiva, bleeding gums and gingival hyperpigmentation. More research and randomized controlled trials are needed on this specific topic for more accurate judgment. Clinical significance: A minimally invasive approach - the usage of vitamin C in dental care could drastically reduce the need for surgical intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20health" title="oral health">oral health</a>, <a href="https://publications.waset.org/abstracts/search?q=periodontology" title=" periodontology"> periodontology</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20C" title=" vitamin C"> vitamin C</a>, <a href="https://publications.waset.org/abstracts/search?q=Gingivitis" title=" Gingivitis"> Gingivitis</a> </p> <a href="https://publications.waset.org/abstracts/161992/the-relation-between-vitamin-c-and-oral-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161992.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">78</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">145</span> Comparative Analysis of Climate Mitigation Strategies Adopted by Farmers of Pakistan and the USA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulfam%20Hasan">Gulfam Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20Ashraf"> Ijaz Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Ashraf"> Saleem Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rafay%20Muzammil"> Muhammad Rafay Muzammil</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Asghar"> Salman Asghar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafiq-Ur-Rehman%20Zia"> Shafiq-Ur-Rehman Zia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The word “climate change” has become the most popular term when anyone observes any uncertain climate variation in their respective region. Asian countries are more prone to the impact of this phenomenon, and Pakistan is the leading affected country. Last few years, governments all over the world have been trying to cater to this issue for the best entrust of their population, especially agriculture. Now the farmers in Pakistan are fully aware of the term “climate change” and are more concerned about its solutions. On the other hand, developed countries like the USA are setting a benchmark for developing countries in every sphere of life. Based on cultural and other variations, the research was carried out to identify the behavior of farmers regarding the same issue. Cross-sectional survey research was designed for an in-depth study of relevant research questions. Face-to-face interviews were conducted in Pakistan, while virtual and face-to-face interviews were conducted in the Indiana State of the USA. The results of the present study and the responses of farmers were very interesting. The common climate change mitigation strategies suggested by farmers of both countries were less use of motor vehicles (replacement with bicycles in the circle of 10 Km), less dependency on chemical fertilizers (increased use of Manure, Bio-fertilizer, Compost), and plantation of the tree. The difference of opinion was in less government interest, lack of farmers’ education, political instability (views of Pakistani farmers), awareness of local communities, self-satisfaction, and economic disparities (views of USA farmers). Based on the given evidence, it was recommended that there is a dire need to address the climate change issue all over the world without discrimination of race, color, region, or religion. Because it will affect not only agriculture but also the real effect will be on HUMANITY. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20strategies" title=" mitigation strategies"> mitigation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=forests" title=" forests"> forests</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/162155/comparative-analysis-of-climate-mitigation-strategies-adopted-by-farmers-of-pakistan-and-the-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162155.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">124</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">144</span> Monitoring Cellular Networks Performance Using Crowd Sourced IoT System: My Operator Coverage (MOC)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassem%20Boshra%20Thabet">Bassem Boshra Thabet</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ibrahim%20Elsabagh"> Mohammed Ibrahim Elsabagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Adly%20Talaat"> Mohammad Adly Talaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The number of cellular mobile phone users has increased enormously worldwide over the last two decades. Consequently, the monitoring of the performance of the Mobile Network Operators (MNOs) in terms of network coverage and broadband signal strength has become vital for both of the MNOs and regulators. This monitoring helps telecommunications operators and regulators keeping the market playing fair and most beneficial for users. However, the adopted methodologies to facilitate this continuous monitoring process are still problematic regarding cost, effort, and reliability. This paper introduces My Operator Coverage (MOC) system that is using Internet of Things (IoT) concepts and tools to monitor the MNOs performance using a crowd-sourced real-time methodology. MOC produces robust and reliable geographical maps for the user-perceived quality of the MNOs performance. MOC is also meant to enrich the telecommunications regulators with concrete, and up-to-date information that allows for adequate mobile market management strategies as well as appropriate decision making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20performance%20monitoring" title="mobile performance monitoring">mobile performance monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=crowd-sourced%20applications" title=" crowd-sourced applications"> crowd-sourced applications</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20broadband%20performance" title=" mobile broadband performance"> mobile broadband performance</a>, <a href="https://publications.waset.org/abstracts/search?q=cellular%20networks%20monitoring" title=" cellular networks monitoring"> cellular networks monitoring</a> </p> <a href="https://publications.waset.org/abstracts/46574/monitoring-cellular-networks-performance-using-crowd-sourced-iot-system-my-operator-coverage-moc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46574.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">396</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">143</span> Tuning of Kalman Filter Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Abdin">Hesham Abdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Zakaria"> Mohamed Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Talaat%20Abd-Elmonaem"> Talaat Abd-Elmonaem</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20El-Din%20Sayed%20Hafez"> Alaa El-Din Sayed Hafez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kalman filter algorithm is an estimator known as the workhorse of estimation. It has an important application in missile guidance, especially in lack of accurate data of the target due to noise or uncertainty. In this paper, a Kalman filter is used as a tracking filter in a simulated target-interceptor scenario with noise. It estimates the position, velocity, and acceleration of the target in the presence of noise. These estimations are needed for both proportional navigation and differential geometry guidance laws. A Kalman filter has a good performance at low noise, but a large noise causes considerable errors leads to performance degradation. Therefore, a new technique is required to overcome this defect using tuning factors to tune a Kalman filter to adapt increasing of noise. The values of the tuning factors are between 0.8 and 1.2, they have a specific value for the first half of range and a different value for the second half. they are multiplied by the estimated values. These factors have its optimum values and are altered with the change of the target heading. A genetic algorithm updates these selections to increase the maximum effective range which was previously reduced by noise. The results show that the selected factors have other benefits such as decreasing the minimum effective range that was increased earlier due to noise. In addition to, the selected factors decrease the miss distance for all ranges of this direction of the target, and expand the effective range which leads to increase probability of kill. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proportional%20navigation" title="proportional navigation">proportional navigation</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20geometry" title=" differential geometry"> differential geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/21005/tuning-of-kalman-filter-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21005.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">510</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">142</span> Reproductive Traits for Holstein Cattle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20M.%20Ward">Ashraf M.

The overall means and standard errors for AFC and CI were 39.4 ± 7.2 months and 487.5 ± 151.6 days respectively. The respective heritability estimates were 0.091 ± 0.05 and 0.044 ± 0.032, while the repeatability estimate for CI was 0.096 ± 0.001. The genetic trends for CI and AFC were -0.6 d/yr and -0.01 mo/yr respectively and were both significant (P < 0.001), indicating a decrease in mean breeding value over the study period. Phenotypic trends were -0.31 mo/yr and -0.35 d/yr for AFC and CI respectively though non-significant (P > 0.05). The low heritability for CI and AFC indicated that temporary environmental influences were much greater than genetic influences or permanent environmental influences on these traits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Holstein" title="Holstein">Holstein</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive" title=" reproductive"> reproductive</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20parameters" title=" genetic parameters"> genetic parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=heritability" title=" heritability "> heritability </a> </p> <a href="https://publications.waset.org/abstracts/18509/reproductive-traits-for-holstein-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18509.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">720</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">141</span> The Effects of Integrating Knowledge Management and e-Learning: Productive Work and Learning Coverage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Ibrahim%20Awad">Ashraf Ibrahim Awad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is important to formulate suitable learning environments ca-pable to be customized according to value perceptions of the university. In this paper, light is shed on the concepts of integration between knowledge management (KM), and e-learning (EL) in the higher education sector of the economy in Abu Dhabi Emirate, United Arab Emirates (UAE). A discussion on and how KM and EL can be integrated and leveraged for effective education and training is presented. The results are derived from the literature and interviews with 16 of the academics in eight universities in the Emirate. The conclusion is that KM and EL have much to offer each other, but this is not yet reflected at the implementation level, and their boundaries are not always clear. Interviews have shown that both concepts perceived to be closely related and, responsibilities for these initiatives are practiced by different departments or units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20integration" title=" learning integration"> learning integration</a>, <a href="https://publications.waset.org/abstracts/search?q=universities" title=" universities"> universities</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a> </p> <a href="https://publications.waset.org/abstracts/34904/the-effects-of-integrating-knowledge-management-and-e-learning-productive-work-and-learning-coverage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34904.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">507</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">140</span> Social Information Seeking: Studying the Effect of Question Type on Responses in Social Q&A Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arshia%20Ayoub">Arshia Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ashraf%20Wani"> Zahid Ashraf Wani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the introduction of online social Q&A sites, people are able to reach each other efficiently for information seeking and simultaneously creating social bonds.

The study employs traditional as well as the modern approach of tracing out the efficiency and integration in the return series. From the results of efficiency it was observed that the market lacked efficiency in terms of its past information. The results of integration test clearly indicates that there was a long memory in the returns of GCC Shariah during the study period.

The cause of recurrence is not clear; however, changes in motor control have been postulated. Objective: To determine the contribution of proximal hip strategy to dynamic balance control in patients with recurrent ankle sprain. Methods: Fifteen subjects with recurrent ankle sprain (group A) and fifteen healthy control subjects (group B) participated in this study. Abductor-adductors as well as flexor-extensor hip musculatures control was abolished by fatigue using the Biodex Isokinetic system. Dynamic balance was measured before and after fatigue by the Biodex Balance system Results: Repeated measures MANOVA was used to compare between and within group differences. In group A fatiguing of hip muscles (flexors-extensors and abductors-adductors) increased overall stability index (OASI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI) significantly (p=0.00) whereas; in group B fatiguing of hip flexors-extensors increased significantly OASI and APSI only (p= 0.017, 0.010; respectively) while fatiguing of hip abductors-adductors has no significant effect on these variables. Moreover, patients with ankle sprain had significantly lower dynamic balance after hip muscles fatigue compared to the control group. Specifically, after hip flexor-extensor fatigue, the OASI, APSI and MLSI were increased significantly than those of the control values (p=0.002, 0.011, and 0.003, respectively) whereas fatiguing of hip abductors-adductors increased significantly in OASI and APSI only (p=0.012, 0.026, respectively). Conclusion: To maintain dynamic balance, patients with recurrent ankle sprain seem to relay more on the hip strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankle%20sprain" title="ankle sprain">ankle sprain</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20muscles%20fatigue" title=" hip muscles fatigue"> hip muscles fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20balance" title=" dynamic balance"> dynamic balance</a> </p> <a href="https://publications.waset.org/abstracts/23132/the-contribution-of-hip-strategy-in-dynamic-balance-in-recurrent-ankle-sprain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23132.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">490</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">131</span> Urban Land Cover from GF-2 Satellite Images Using Object Based and Neural Network Classifications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamyaa%20Gamal%20El-Deen%20Taha">Lamyaa Gamal El-Deen Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Sharawi"> Ashraf Sharawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China launched satellite GF-2 in 2014.

In this paper, we evaluate the usability of various android and iPhone applications for blind people through analysis and surveys. This paper aspires to provide guidance in order to increase smartphone application accessibility for the visually impaired. An abstract application design is also proposed to overcome usability issues in smartphone applications for visually challenged people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eyes-free%20shell" title="eyes-free shell">eyes-free shell</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title=" human computer interaction"> human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20engineering" title=" usability engineering"> usability engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=visually%20challenged" title=" visually challenged"> visually challenged</a> </p> <a href="https://publications.waset.org/abstracts/8962/usability-issues-of-smart-phone-applications-for-visually-challenged-people" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8962.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">364</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">128</span> Response of Full-Scale Room Building Against Blast Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eid%20Badshah">Eid Badshah</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Naseer"> Amjad Naseer</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ashraf"> Muhammad Ashraf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper full-scale brick masonry room along with the veranda of a typical school building was subjected to eight successive blast tests with increasing charge weights ranging from 0.5kg to 16.02kg at 3.66m fixed stand-off distance.

The immobilization of 2,6-dichlorophenolindophenol with MWCNTs was performed with a new synthetic strategy and characterized by UV–visible absorption spectroscopy, Fourier transform infrared spectroscopy and cyclic voltammetry. The cyclic voltammetric response of DPIP grafted onto MWCNTs indicated that it promotes the low potential, sensitive and stable determination of sulfide. The dependence of response currents on the concentration of sulfide was examined and was linear in the range of 10 - 1100 µM. The detection limit of sulfide was 5 µM and RSD for 100 and 500 µM sulfides were 1.8 and 1.3 %. Many interfering species had little or no effect on the determination of sulfide. The procedure was applied to determination of sulfide in waters samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functionalized%20carbon%20nanotubes" title="functionalized carbon nanotubes">functionalized carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfide" title=" sulfide"> sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20samples" title=" biological samples"> biological samples</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title=" 2"> 2</a>, <a href="https://publications.waset.org/abstracts/search?q=6-dichlorophenolindophenol" title="6-dichlorophenolindophenol">6-dichlorophenolindophenol</a> </p> <a href="https://publications.waset.org/abstracts/48303/a-synthetic-strategy-to-attach-26-dichlorophenolindophenol-onto-multi-walled-carbon-nanotubes-and-their-application-for-electrocatalytic-determination-of-sulfide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48303.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">313</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">125</span> Development of a Numerical Model to Predict Wear in Grouted Connections for Offshore Wind Turbine Generators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20Dallyn">Paul Dallyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20El-Hamalawi"> Ashraf El-Hamalawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Palmeri"> Alessandro Palmeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bob%20Knight"> Bob Knight</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to better understand the long term implications of the grout wear failure mode in large-diameter plain-sided grouted connections, a numerical model has been developed and calibrated that can take advantage of existing operational plant data to predict the wear accumulation for the actual load conditions experienced over a given period, thus limiting the need for expensive monitoring systems.

The largest and oldest area of mangroves can be found around Al-Thakhira and Al-Khor. Other mangrove areas originate from fairly recent plantings by the government, although unfortunately the picturesque mangrove lake in Al-Wakra has now been uprooted. Avicinnia marina is the predominant mangrove species found in the region. Mangroves protect and stabilize low lying coastal land, and provide protection and food sources for estuarine and coastal fishery food chains. They also serve as feeding, breeding and nursery grounds for a variety of fish, crustaceans, reptiles, birds and other wildlife. A total of 21 individuals of A. marina, representing seven diverse Natural and artificial populations, were sampled throughout its range in Qatar. Leaves from 2-3 randomly selected trees at each location were collected. The locations are as follows: Al-Rawis, Ras-Madpak, Fuwairt, Summaseima, Al-khour, AL-Mafjar and Zekreet. Total genomic DNA was extracted using commercial DNeasy Plant System (Qiagen, Inc., Valencia, CA) kit to be used for genetic diversity analysis. Total of 12 (Inter-Simple Sequence Repeat) ISSR primers were used to amplify DNA fragments using genomic DNA. The 12 ISSR primers amplified polymorphic bands among mangrove samples in different areas as well as within each area indicating the existing of variation within each area and among the different areas of mangrove in Qatar. The results could characterize Avicinnia marina populations exist in different areas of Qatar and establish DNA fingerprint documentations for mangrove population to be used in further studies. Moreover, existing of genetic variation within and among Avicinnia marina populations is a strong indication for the ability of such populations to adapt different environmental conditions in Qatar. This study could be a warning to save mangrove in Qatar and save the environment as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20fingerprint" title="DNA fingerprint">DNA fingerprint</a>, <a href="https://publications.waset.org/abstracts/search?q=Avicinnia%20marina" title=" Avicinnia marina"> Avicinnia marina</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20analysis" title=" genetic analysis"> genetic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Qatar" title=" Qatar"> Qatar</a> </p> <a href="https://publications.waset.org/abstracts/30094/genetic-analysis-of-the-endangered-mangrove-species-avicennia-marina-in-qatar-detected-by-inter-simple-sequence-repeat-dna-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30094.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">405</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">122</span> The Role of Public Education in Increasing Public Awareness through Mass Media with Emphasis on Newspapers and TV: Coping with Possible Earthquake in Tehran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naser%20Charkhsaz">Naser Charkhsaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Sadat%20Mousavi"> Ashraf Sadat Mousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Navvab%20Shamspour"> Navvab Shamspour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to evaluate the role of state education in increasing public awareness through mass media (with emphasis on newspapers and TV) coping with possible earthquake in Tehran.

Weight loss method was used for measuring the corrosion rate of the carbon steel specimens immersed in technical white oil at 100ºC at various time intervals in absence and presence of the two sulphur compounds. The corroded specimens are examined using the chemical wear test, scratch test and hardness test. The scratch test is carried out using scratch loads from 0.5 Kg to 2.0 Kg. The scratch width is obtained at various scratch load and test conditions. The Brinell hardness test is carried out and investigated for both corroded and inhibited specimens.
