Such structures are exposed to severe cyclic loading throughout their lifetime often resulting in fatigue damage to structural components and a reduction in the service life of the structure. Since experimental and numerical results on the fatigue performance of FRP-to-concrete joints are still limited, the current research focuses on assessing the fatigue performance of externally bonded FRP-to-concrete joints using a direct shear test. Some early results indicate that the stress ratio and the applied cyclic stress level have a direct influence on the fatigue life of the externally bonded FRP. In addition, a calibrated finite element model is developed to provide further insight into the influence of certain parameters such as: concrete strength, FRP thickness, number of cycles, frequency and stiffness on the fatigue life of the FRP-to-concrete joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FRP" title="FRP">FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20bond" title=" concrete bond"> concrete bond</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a> </p> <a href="https://publications.waset.org/abstracts/41613/finite-element-assessment-on-bond-behaviour-of-frp-to-concrete-joints-under-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41613.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">449</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">5</span> Calibrating Risk Factors for Road Safety in Low Income Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Al-Nuaimi">Atheer Al-Nuaimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Harry%20Evdorides"> Harry Evdorides</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Daily, many individuals die or get harmed on streets around the globe, which requires more particular solutions for transport safety issues. International road assessment program (iRAP) is one of the models that are considering many variables which influence road user’s safety. In iRAP, roads have been partitioned into five-star ratings from 1 star (the most reduced level) to 5 star (the most noteworthy level). These levels are calculated from risk factors which represent the effect of the geometric and traffic conditions on rod safety. The result of iRAP philosophy are the countermeasures that can be utilized to enhance safety levels and lessen fatalities numbers. These countermeasures can be utilized independently as a single treatment or in combination with other countermeasures for a section or an entire road. There is a general understanding that the efficiency of a countermeasure is liable to reduction when it is used in combination with various countermeasures. That is, crash diminishment estimations of single countermeasures cannot be summed easily. In the iRAP model, the fatalities estimations are calculated using a specific methodology. However, this methodology suffers overestimations. Therefore, this study has developed a calibration method to estimate fatalities numbers more accurately. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crash%20risk%20factors" title="crash risk factors">crash risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20road%20assessment%20program" title=" international road assessment program"> international road assessment program</a>, <a href="https://publications.waset.org/abstracts/search?q=low-income%20countries" title=" low-income countries"> low-income countries</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a> </p> <a href="https://publications.waset.org/abstracts/106648/calibrating-risk-factors-for-road-safety-in-low-income-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106648.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">146</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">4</span> Effect of Air Temperatures (°C) and Slice Thickness (mm) on Drying Characteristics and Some Quality Properties of Omani Banana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Al-Maqbali">Atheer Al-Maqbali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Al-Rizeiqi"> Mohammed Al-Rizeiqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Pathare"> Pankaj Pathare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is an ever-increased demand for the consumption of banana products in Oman and elsewhere in the region due to the nutritional value and the decent taste of the product. There are approximately 3,751 acres of land designated for banana cultivation in the Sultanate of Oman, which produces approximately 18,447 tons of banana product. The fresh banana product is extremely perishable, resulting in a significant post-harvest economic loss. Since the product has high sensory acceptability, the drying method is a common method for processing fresh banana products. This study aims to use the drying technology in the production of dried bananas to preserve the largest amount of natural color and delicious taste for the consumer. The study also aimed to assess the shelf stability of both water activity (aw) and color (L*, a*, b*) for fresh and finished dried bananas by using a Conventional Air Drying System. Water activity aw, color characteristic L a b, and product’s hardness were analyzed for 3mm, 5mm, and7 mm thickness at different temperaturesoC. All data were analyzed statistically using STATA 13.0, and α ≤ 0.05 was considered for the significance level. The study is useful to banana farmers to improve cultivation, food processors to optimize producer’s output and policy makers in the optimization of banana processing and post-harvest management of the products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=banana" title="banana">banana</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=oman" title=" oman"> oman</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness" title=" thickness"> thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=color" title=" color"> color</a> </p> <a href="https://publications.waset.org/abstracts/154491/effect-of-air-temperatures-c-and-slice-thickness-mm-on-drying-characteristics-and-some-quality-properties-of-omani-banana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154491.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Knowledge and Attitude towards Helicobacter pylori: Awareness about Health Impacts of H. pylori Gastric Ulcer and Its Carcinogenic Potential among Adults in Sharjah</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Malek">Abdullah Malek</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzn%20Al%20Khaldi"> Muzn Al Khaldi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lian%20Odeh"> Lian Odeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Tariq"> Atheer Tariq</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Al%20Fardan"> Mohammad Al Fardan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiba%20Barqawi"> Hiba Barqawi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> H. pylori bacterium is a known underlying agent for gastritis, peptic ulcer disease, and gastric cancer and is believed to infect half of the world’s population. Even with the ubiquity of H. pylori bacterium, there is lack of knowledge regarding its modes of transmission, associated diseases, carcinogenic effect and means of prevention; especially in the UAE. A cross sectional study of 500 participants, of which 58% (n= 289) of the respondents were female, and 42% (n=210) were male, was conducted in Sharjah to assess the knowledge, and explore the attitudes and practices among UAE residents towards Helicobacter Pylori and its associated PUD as well as its carcinogenic nature. A structured self-administered questionnaire was distributed to the target population to establish their demographic background and selected aspects of their lifestyle. General knowledge about H. Pylori was poor, only 24.6% stated they have heard of H. pylori. Attitudes towards prevention and practices were relatively poor as well. Subjects who suffered from severe symptoms (ALARM symptoms) had significantly lower habit scores than those with mild and moderate symptoms (p=0.0078**). To the authours’ knowledge, no previous studies were conducted in the United Arab Emirates regarding the epidemiology of the infection to detect the extent of H. Pylori’s impact on the public health. The results of this study can be used to draw conclusions about the average knowledge of the UAE population regarding H. pylori. It can also be a starting point to devise new education programs and campaigns that raise awareness of this health issue which could be easily avoided with early diagnosis and antibiotic treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20gastritis" title="chronic gastritis">chronic gastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20health" title=" community health"> community health</a>, <a href="https://publications.waset.org/abstracts/search?q=gastric%20cancer" title=" gastric cancer"> gastric cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Helicobacter%20pylori" title=" Helicobacter pylori"> Helicobacter pylori</a>, <a href="https://publications.waset.org/abstracts/search?q=peptic%20ulcers" title=" peptic ulcers"> peptic ulcers</a> </p> <a href="https://publications.waset.org/abstracts/81751/knowledge-and-attitude-towards-helicobacter-pylori-awareness-about-health-impacts-of-h-pylori-gastric-ulcer-and-its-carcinogenic-potential-among-adults-in-sharjah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81751.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">259</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">2</span> Clinicopathological and Immunohistochemical Study of Ovarian Sex Cord-Stromal Tumors and Their Histological Mimics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Esheba">Ghada Esheba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebtisam%20Aljerayan"> Ebtisam Aljerayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Afnan%20Al-Ghamdi"> Afnan Al-Ghamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Alsharif"> Atheer Alsharif</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20alzahrani"> Hanan alzahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Primary ovarian neoplasms comprise a heterogeneous group of tumors of three main subtypes: surface epithelial, germ cell, and sex cord-stromal. The wide morphological variation within and between these groups can result in diagnostic difficulties. Gonadal sex cord-stromal tumors (SCST) represent one of the most heterogeneous categories of human neoplasms, because they may contain various combinations of different gonadal sex cord and stromal element. Aim: The aim of this work is to highlight the clinicopathological characteristics of SCST and to assess the value of alpha-inhibin and calretinin in the distinction between SCST and their mimics. Material and methods: This study was carried out on 100 cases using full tissue sections; 70 cases were SCST and 30 cases were histological mimics of SCST. The cases were studied using immunohistochemically using alpha-inhibin. In addition, an ovarian tissue microarray containing 170 benign and malignant ovarian neoplasms was also studied immunohistochemically for calretinin expression. The ovarian microarray included 14 SCST, 59 ovarian serous borderline tumors, 17 mucinous borderline tumors, 10 mucinous adenocarcinomas, 32 endometrioid adenocarcinomas, 34 clear cell carcinomas, and 4 germ cell tumors. Results: 99% of SCST examined using full tissue sections exhibited positive cytoplasmic staining for inhibin. On the contrary, only 7% of the histological mimics (P value < 0.0001). 86% of SCST in the tissue microarray were positive for calretinin with nuclear and/or cytoplasmic staining compared to only 7% of the other tumor types (P value < 0.0001). Conclusions: SCST have characteristic clinicopathological and immunohistochemical features and their recognition is crucial for proper diagnosis and treatment. Alpha-inhibin and calretinin are of great help in the diagnosis of sex cord-stromal tumors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calretinin" title="calretinin">calretinin</a>, <a href="https://publications.waset.org/abstracts/search?q=granulosa%20cell%20tumor" title=" granulosa cell tumor"> granulosa cell tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibin" title=" inhibin"> inhibin</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20cord-stromal%20tumors" title=" sex cord-stromal tumors "> sex cord-stromal tumors </a> </p> <a href="https://publications.waset.org/abstracts/40762/clinicopathological-and-immunohistochemical-study-of-ovarian-sex-cord-stromal-tumors-and-their-histological-mimics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40762.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">208</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">1</span> Exploration and Evaluation of the Effect of Multiple Countermeasures on Road Safety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Al-Nuaimi">Atheer Al-Nuaimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Harry%20Evdorides"> Harry Evdorides</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every day many people die or get disabled or injured on roads around the world, which necessitates more specific treatments for transportation safety issues. International road assessment program (iRAP) model is one of the comprehensive road safety models which accounting for many factors that affect road safety in a cost-effective way in low and middle income countries. In iRAP model road safety has been divided into five star ratings from 1 star (the lowest level) to 5 star (the highest level). These star ratings are based on star rating score which is calculated by iRAP methodology depending on road attributes, traffic volumes and operating speeds. The outcome of iRAP methodology are the treatments that can be used to improve road safety and reduce fatalities and serious injuries (FSI) numbers. These countermeasures can be used separately as a single countermeasure or mix as multiple countermeasures for a location. There is general agreement that the adequacy of a countermeasure is liable to consistent losses when it is utilized as a part of mix with different countermeasures. That is, accident diminishment appraisals of individual countermeasures cannot be easily added together. The iRAP model philosophy makes utilization of a multiple countermeasure adjustment factors to predict diminishments in the effectiveness of road safety countermeasures when more than one countermeasure is chosen. A multiple countermeasure correction factors are figured for every 100-meter segment and for every accident type. However, restrictions of this methodology incorporate a presumable over-estimation in the predicted crash reduction. This study aims to adjust this correction factor by developing new models to calculate the effect of using multiple countermeasures on the number of fatalities for a location or an entire road. Regression models have been used to establish relationships between crash frequencies and the factors that affect their rates. Multiple linear regression, negative binomial regression, and Poisson regression techniques were used to develop models that can address the effectiveness of using multiple countermeasures. Analyses are conducted using The R Project for Statistical Computing showed that a model developed by negative binomial regression technique could give more reliable results of the predicted number of fatalities after the implementation of road safety multiple countermeasures than the results from iRAP model. The results also showed that the negative binomial regression approach gives more precise results in comparison with multiple linear and Poisson regression techniques because of the overdispersion and standard error issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20road%20assessment%20program" title="international road
