breast cancer diagnosis and therapy by providing sophisticated solutions for screening, imaging interpretation, histopathological analysis, and treatment planning. This literature review digs into the many uses of AI in breast cancer treatment, highlighting the need for collaboration between AI scientists and healthcare practitioners. It emphasizes advances in AI-driven breast imaging interpretation, such as computer-aided detection and diagnosis (CADe/CADx) systems and deep learning algorithms. These have shown significant potential for improving diagnostic accuracy and lowering radiologists' workloads. Furthermore, AI approaches such as deep learning have been used in histopathological research to accurately predict hormone receptor status and categorize tumor-associated stroma from regular H&E stains. These AI-powered approaches simplify diagnostic procedures while providing insights into tumor biology and prognosis. As AI becomes more embedded in breast cancer care, it is crucial to ensure its ethical, efficient, and patient-focused implementation to improve outcomes for breast cancer patients ultimately. <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 href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20diagnosis" title=" cancer diagnosis"> cancer diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20practice" title=" clinical practice"> clinical practice</a> </p> <a href="https://publications.waset.org/abstracts/186186/integrating-ai-into-breast-cancer-diagnosis-aligning-perspectives-for-effective-clinical-practice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186186.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">69</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 Importance of Imaging and Functional Tests for Early Detection of Occupational Diseases in Kosovo's Miners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krenare%20Shabani">Krenare Shabani</a>, <a href="https://publications.waset.org/abstracts/search?q=Kreshnike%20Dedushi%20Hoti"> Kreshnike Dedushi Hoti</a>, <a href="https://publications.waset.org/abstracts/search?q=Serbeze%20Kabashi"> Serbeze Kabashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeton%20Shatri"> Jeton Shatri</a>, <a href="https://publications.waset.org/abstracts/search?q=Arben%20Rroji"> Arben Rroji</a>, <a href="https://publications.waset.org/abstracts/search?q=Mrik%C3%AB%20Bunjaku"> Mrikë Bunjaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Leotrim%20Berisha"> Leotrim Berisha</a>, <a href="https://publications.waset.org/abstracts/search?q=Jona%20Kosova"> Jona Kosova</a>, <a href="https://publications.waset.org/abstracts/search?q=Edmond%20Puca"> Edmond Puca</a>, <a href="https://publications.waset.org/abstracts/search?q=Bleriana%20Shabani"> Bleriana Shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Workers in Kosovo's mining industry are subjected to hazardous working conditions and airborne particles, such as silica dust, which can cause silicosis and other severe respiratory illnesses. The purpose of this research is to assess the health impacts of such exposures, as well as the importance of imaging and functional testing in detecting pathological changes early on. Methodology: The study is prospective and cross-sectional and was carried out during the year 2024. 626 people (446 miners and 180 non-miners) were enrolled in the study. Subjects underwent spirometry and chest radiography. Data were analysed with SPSS24. Results: The average age of the participants is 48 years. Demographics and Smoking: Smoking was common among young miners. Radiological Changes: Radiographic abnormalities in the lungs were seen in 23.1% of miners and 10.6% of non-miners, including small irregular opacities and emphysematous changes. Lung Function: The FEV1/FVC ratio decreased with increased exposure time, indicating a decline in pulmonary function.Impact of Exposure Duration: Longer exposure duration was associated with a higher number of miners experiencing coughs and requiring medical consultations such as CT scans and biopsies. Conclusions: Medical imaging and functional testing are critical for early diagnosis of lung abnormalities in miners.Findings demonstrate a strong correlation between extended exposure to mine dust and the development of respiratory disorders, emphasising the importance of preventative measures and routine health monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silicosis" title="silicosis">silicosis</a>, <a href="https://publications.waset.org/abstracts/search?q=miners" title=" miners"> miners</a>, <a href="https://publications.waset.org/abstracts/search?q=imaging" title=" imaging"> imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=spirometry" title=" spirometry"> spirometry</a> </p> <a href="https://publications.waset.org/abstracts/189816/the-importance-of-imaging-and-functional-tests-for-early-detection-of-occupational-diseases-in-kosovos-miners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189816.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">28</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">29</span> Cosmic Radiation Hazards and Protective Strategies in Space Exploration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrnaz%20Mostafavi">Mehrnaz Mostafavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Azani"> Alireza Azani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Shabani"> Mahtab Shabani</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Ghafari"> Fatemeh Ghafari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While filled with promise and wonder, space exploration also presents significant challenges, one of the foremost being the threat of cosmic radiation to astronaut health. Recent advancements in assessing these risks and developing protective strategies have shed new light on this issue. Cosmic radiation encompasses a variety of high-energy particles originating from sources like solar particle events, galactic cosmic rays, and cosmic rays from beyond the solar system. These particles, composed of protons, electrons, and heavy ions, pose a substantial threat to human health in space due to the lack of Earth's protective atmosphere and magnetic field. Researchers have made significant progress in assessing the risks associated with cosmic radiation exposure. By employing advanced dosimetry techniques and conducting biological studies, they have gained insights into how cosmic radiation affects astronauts' health, including increasing the risk of cancer and radiation sickness. This research has led to personalized risk assessment methods tailored to individual astronaut profiles. Distinctive protection strategies have been proposed to combat the dangers of cosmic radiation. These include developing spacecraft shielding materials and designs to enhance radiation protection. Additionally, researchers are exploring pharmacological interventions such as radioprotective drugs and antioxidant therapies to mitigate the biological effects of radiation exposure and preserve astronaut well-being. The findings from recent research have significant implications for the future of space exploration. By advancing our understanding of cosmic radiation risks and developing effective protection strategies, we pave the way for safer and more sustainable human missions beyond Earth's orbit. This is especially crucial for long-duration missions to destinations like Mars, where astronauts will face prolonged exposure to cosmic radiation. In conclusion, recent research has marked a milestone in addressing the challenges posed by cosmic radiation in space exploration. By delving into the complexities of cosmic radiation exposure and developing innovative protection strategies, scientists are ensuring the health and resilience of astronauts as they venture into the vast expanse of the cosmos. Continued research and collaboration in this area are essential for overcoming the cosmic radiation challenge and enabling humanity to embark on new frontiers of exploration and discovery in space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Space%20exploration" title="Space exploration">Space exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=cosmic%20radiation" title=" cosmic radiation"> cosmic radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=astronaut%20health" title=" astronaut health"> astronaut health</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=protective%20strategies" title=" protective strategies"> protective strategies</a> </p> <a href="https://publications.waset.org/abstracts/186188/cosmic-radiation-hazards-and-protective-strategies-in-space-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186188.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">28</span> Investigating the Relationship between Growth, Beta and Liquidity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Amirhosseini">Zahra Amirhosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Nameni"> Mahtab Nameni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to investigate the relationship between growth, beta, and Company's cash.

Varying ratios of EPDM to EPDM-g-MA were examined. As the proportion of EPDM-g-MA increased, an interlayer phase formed between the dispersed PA6 domains and the PP matrix. This resulted in the development of a core-shell encapsulation morphology within the blends. The concentration of the EPDM-g-MA component is inversely correlated with the average size of PA6 particles. Additionally, blends containing higher proportions of the EPDM-g-MA rubbery phase exhibited an aggregated structure of the modifier particles. Notably, as the concentration of EPDM-g-MA increased from 0% to 15% in the blend, there was a consistent monotonic reduction in the size of PA6 particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20morphology" title="phase morphology">phase morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=rubbery%20phase" title=" rubbery phase"> rubbery phase</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber%20functionality" title=" rubber functionality"> rubber functionality</a>, <a href="https://publications.waset.org/abstracts/search?q=ternary%20blends" title=" ternary blends"> ternary blends</a> </p> <a href="https://publications.waset.org/abstracts/182166/study-the-effect-of-rubbery-phase-on-morphology-development-of-pppa6epdmepdm-g-ma-ternary-blends" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182166.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">90</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">25</span> Effects of Alkaline Pretreatment Parameters on the Corrosion Resistance and ‎Wettability of Magnesium Implant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Assadian">Mahtab Assadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hasbullah%20Idris"> Mohd Hasbullah Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Rezazadeh%20Shirdar"> Mostafa Rezazadeh Shirdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Taheri"> Mohammad Mahdi Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=%E2%80%8ES.%20Izman"> ‎S.

Creation of Mg(OH)2 barrier layer after pretreatment enhanced corrostion resistance as well as wettability of substrate surface. Characterization including Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) was conducted to detect the existence of this barrier layer. Surface roughness and wettability of substrate was evaluated using atomic force microscopy (AFM) and contact angle measurement respectively. It is found that magnesium treated by 1M NaOH for 30 min reveals higher corrosion resistance and lower water contact angle of substrate surface. In addition, this investigation indicates that pH value of SBF solution is strongly influenced by different time and concentration of alkaline pretreatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium" title="magnesium">magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=NaOH%20pretreatment" title=" NaOH pretreatment"> NaOH pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance"> corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=wettability" title=" wettability"> wettability</a> </p> <a href="https://publications.waset.org/abstracts/14548/effects-of-alkaline-pretreatment-parameters-on-the-corrosion-resistance-and-wettability-of-magnesium-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14548.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">961</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">24</span> Thermo-Hydro-Mechanical Modeling of Landfill Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Delfan%20Azari">Mahtab Delfan Azari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Noorzad"> Ali Noorzad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Mahboubi%20Ardakani"> Ahmadreza Mahboubi Ardakani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Municipal solid waste landfills have relatively high temperature which is caused by anaerobic and aerobic degradation. The temperature that is produced is almost 40-70°C. Since this temperature will remain for many years, considering it for studying landfill behavior and its soil is so important. By considering the temperature of landfill, the obtained results will become more logical and more realistic. Vertical displacement and differential settlement are two important values which are studied here. Differential displacements could expand cracks in liner and cover. If cracks appear in the liner, the leachate and gases will propagate to media and hence should be noticed carefully. The present research is focused on the thermo-hydro-mechanical modeling of landfill with finite element method. First, the heat transfer of the landfill is modeled and the temperature is estimated. Then, the results of thermo-hydro-mechanical results are presented to investigate landfill behavior more accurately. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill%20behavior" title=" landfill behavior"> landfill behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-hydro-mechanical%20modeling" title=" thermo-hydro-mechanical modeling"> thermo-hydro-mechanical modeling</a> </p> <a href="https://publications.waset.org/abstracts/7666/thermo-hydro-mechanical-modeling-of-landfill-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7666.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">348</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">23</span> Diesel Engine Performance Optimization to Reduce Fuel Consumption and Emissions Issues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=hadi%20kargar">hadi kargar</a>, <a href="https://publications.waset.org/abstracts/search?q=bahador%20shabani"> bahador shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, 16 cylinder motor combustion CFD modeling with a diameter of 165 mm and 195 mm along the way to help the FIRE software to optimize its function to work.

For this purpose, 5 different anode tips are used. The shapes of the uppermost region of these anodes have been cylindrical-flat, cylindrical-hollow, spherical-convex, cone-flat and cone-hollow. Analyzed data have shown that cone-flat, spherical-convex and cone-hollow anodes significantly increase X-ray intensity respectively in comparison with cylindrical-flat anode; while the cylindrical-hollow tip decreases. Anode radius reduction at its end in conic or spherical anodes enhance SXR by increasing plasma density through collecting a greater mass of gas and more gradual transition phase to form a more stable dense plasma pinch. Also, HXR is enhanced by increasing the energy of electrons colliding with the anode surface through raise of induced electrical field. Finally, the cone-flat anode is introduced to use in cases in which the plasma focus device is used as an X-ray source due to its highest yield of X-ray emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasma%20focus" title="plasma focus">plasma focus</a>, <a href="https://publications.waset.org/abstracts/search?q=anode%20tip" title=" anode tip"> anode tip</a>, <a href="https://publications.waset.org/abstracts/search?q=HXR" title=" HXR"> HXR</a>, <a href="https://publications.waset.org/abstracts/search?q=SXR" title=" SXR"> SXR</a>, <a href="https://publications.waset.org/abstracts/search?q=pinched%20plasma" title=" pinched plasma"> pinched plasma</a> </p> <a href="https://publications.waset.org/abstracts/30370/analysis-of-soft-and-hard-x-ray-intensities-using-different-shapes-of-anodes-in-a-4kj-mather-type-plasma-focus-facility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30370.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">400</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">21</span> Provisions for Risk in Islamic Banking and Finance in Comparison to the Conventional Banks in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashid%20Masoud%20Ali%20Al-Mazrui">Rashid Masoud Ali Al-Mazrui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramadhani%20Mashaka%20Shabani"> Ramadhani Mashaka Shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Islamic banks and financial institutions are exposed to the same risks as conventional banking. These risks include the rate return risk, credit or market risk, liquidity risk, and operational risk among others. However, being a financial institution that operates Islamic banking and finance operations, there is additional risk associated with its operations different from conventional finance, such as displacing commercial risk. They face Shari'ah compliance risks because of their failure to follow Shari'ah principles. To have proper mitigation and risk management, banks should have proper risk management policies to mitigate risks. This paper aims to study the risk management taken by Islamic banks in comparison with conventional banks. Also, the study evaluates the provisions for risk management taken by selected Islamic banks and conventional banks. The study employs qualitative analysis using secondary data by applying a content analysis approach with a sample size of 4 Islamic banks and four conventional banks ranging from 2010 to 2020. We find that these banks all use the same technique, except for the associated risk. The extra ways are used, but only for additional risks that are available to Islamic banking and finance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emerging%20risk" title="emerging risk">emerging risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title=" Islamic banking"> Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20bank" title=" conventional bank"> conventional bank</a> </p> <a href="https://publications.waset.org/abstracts/155652/provisions-for-risk-in-islamic-banking-and-finance-in-comparison-to-the-conventional-banks-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155652.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">83</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">20</span> International Student Recruitment in Higher Education: A Comparative Study of the Countries in the Middle East</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Arabkheradmand">Ali Arabkheradmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Enayat%20A.%20Shabani"> Enayat A.

Several mining projects have seen the successful and economic beneficial use of TBMs, and there is an increasing awareness of the benefits of TBMs for mining projects. Key technical considerations for the use of TBMs for the construction of tunnels for mining projects include geological issues (rock type, rock alteration, rock strength, rock abrasivity, durability, ground water inflows), depth of cover and the potential for overstressing/rockbursts, site access and terrain, portal locations, TBM constraints, minimum tunnel size, tunnel support requirements, contractor and labor experience, and project schedule demands. This study focuses on tunnelling mining, with the goal to develop methods and tools to be used to gain understanding of these processes, and to analyze metro of Tehran. The Metro Line 7 of Tehran is one of the Longest (26 Km) and deepest (27m) of projects that’s under implementation. Because of major differences like passing under all geotechnical layers of the town and encountering part of it with underground water table and also using mechanized excavation system, is one of special metro projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TBM" title="TBM">TBM</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel%20boring%20machines%20economic" title=" tunnel boring machines economic"> tunnel boring machines economic</a>, <a href="https://publications.waset.org/abstracts/search?q=metro" title=" metro"> metro</a>, <a href="https://publications.waset.org/abstracts/search?q=line%207" title=" line 7"> line 7</a> </p> <a href="https://publications.waset.org/abstracts/35487/analysis-mechanized-boring-tbm-of-tehran-subway-line-7" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35487.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">384</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">18</span> Perceptions of Greenhouse Vegetable Growers Regarding Use of Biological Control Practices: A Case Study in Jiroft County, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Shabanali%20Fami">Hossein Shabanali Fami</a>, <a href="https://publications.waset.org/abstracts/search?q=Omid%20Sharifi"> Omid Sharifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Javad%20Ghasemi"> Javad Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Pouratashi"> Mahtab Pouratashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Sadat%20Moghadasian"> Mona Sadat Moghadasian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this study was to investigate perception of greenhouse vegetable growers regarding use of biological control practices during the growing season.

The simulator is developed on MATLAB providing the possibility to analyze and simulate energy consumption of frequently used home appliances in Albania. Modelling of devices considers the impact of different factors, mentioning occupant behavior and climacteric conditions. Most devices are modeled as an electric circuit, and the electric energy consumption is estimated by the solutions of the guiding differential equations. The provided models refer to devices like a dishwasher, oven, water heater, air conditioners, light bulbs, television, refrigerator water, and pump. The proposed model allows us to simulate beforehand the energetic behavior of the largest consumption home devices to estimate peak consumption and improving its reduction. Simulated home prototype results are compared to real measurement of a considered typical home. Obtained results from simulator framework compared to monitored typical household using EmonTxV3 show the effectiveness of the proposed simulation. This conclusion will help for future simulation of a large group of typical household for a better understanding of peak consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20appliances" title="electrical appliances">electrical appliances</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management" title=" energy management"> energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20estimation" title=" peak estimation"> peak estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20home" title=" smart home"> smart home</a> </p> <a href="https://publications.waset.org/abstracts/102950/modelling-home-appliances-for-energy-management-system-comparison-of-simulation-results-with-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102950.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">164</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">15</span> Predictive Analytics of Student Performance Determinants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Davari">Mahtab Davari</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Edward%20Okon"> Charles Edward Okon</a>, <a href="https://publications.waset.org/abstracts/search?q=Somayeh%20Aghanavesi"> Somayeh Aghanavesi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every institute of learning is usually interested in the performance of enrolled students. The level of these performances determines the approach an institute of study may adopt in rendering academic services. The focus of this paper is to evaluate students' academic performance in given courses of study using machine learning methods. This study evaluated various supervised machine learning classification algorithms such as Logistic Regression (LR), Support Vector Machine, Random Forest, Decision Tree, K-Nearest Neighbors, Linear Discriminant Analysis, and Quadratic Discriminant Analysis, using selected features to predict study performance. The accuracy, precision, recall, and F1 score obtained from a 5-Fold Cross-Validation were used to determine the best classification algorithm to predict students’ performances. SVM (using a linear kernel), LDA, and LR were identified as the best-performing machine learning methods. Also, using the LR model, this study identified students' educational habits such as reading and paying attention in class as strong determinants for a student to have an above-average performance. Other important features include the academic history of the student and work. Demographic factors such as age, gender, high school graduation, etc., had no significant effect on a student's performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=student%20performance" title="student performance">student performance</a>, <a href="https://publications.waset.org/abstracts/search?q=supervised%20machine%20learning" title=" supervised machine learning"> supervised machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-validation" title=" cross-validation"> cross-validation</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/155072/predictive-analytics-of-student-performance-determinants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155072.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">126</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">14</span> Death Anxiety and Life Expectancy among Older Adults in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Rashedi">Vahid Rashedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Banafsheh%20Ebrahimi"> Banafsheh Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Sharif%20Mohseni"> Mahtab Sharif Mohseni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadali%20Hosseini"> Mohammadali Hosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: One of the metrics used to evaluate health status is life expectancy. This index alters as people age as a result of several events, illnesses, stress, and anxiety. One of the issues that might develop into a lethal phobia is death anxiety. This study looked at older persons in Tehran, Iran, to see if there was any correlation between life expectancy and fear of dying. Methods: Cluster random sampling was used to select 208 older persons (age 60) who had been sent to adult daycare facilities in Tehran for this correlational descriptive study. A demographic questionnaire, Temper's death anxiety scale, and Snyder's life expectancy scale were used to gather the data. Statistical Package for the Social Sciences softwear version 22 was used to conduct the data analysis. Results: The average age of the senior citizens was 66.60 (6.58) years. With a mean life expectancy of 24.94, it was discovered that the average death anxiety was 12.21. Additionally, Pearson's correlation coefficient demonstrated a bad correlation between fear of dying and life expectancy. Age, residential status, and death fear were the three primary predictors of a decline in life expectancy, according to multiple regression analysis. Conclusion: The findings suggest that there is a link between death fear and a lower life expectancy, which calls for the use of appropriate strategies to increase older individuals' life expectancies as well as the teaching of anxiety coping mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aged" title="aged">aged</a>, <a href="https://publications.waset.org/abstracts/search?q=frailty" title=" frailty"> frailty</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=life" title=" life"> life</a> </p> <a href="https://publications.waset.org/abstracts/164128/death-anxiety-and-life-expectancy-among-older-adults-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164128.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">85</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">13</span> Potential Positive Impacts of Online Communities on Mental Health of Women Who Have Experienced Miscarriage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Talafian">Mahtab Talafian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the advent of technology over the last decades, participation in online communities and discussion forums has become increasingly popular. Many studies have been done on the negative role of the online world on human beings’ psychological well-being and mental health, while relatively less attention has been given to the potentially positive role of technology in promoting mental health. Miscarriage is a common and emotionally challenging experience for women, and online communities seem to be a potential source of support for them. This study aimed to firstly find the most common types of support communicated in online communities of women who have miscarried and, secondly, investigate if there is a relationship between participation in online communities and mental health outcomes after miscarriage. In this study, three research methodologies, including content analysis, survey and interview, were employed to answer the research questions. With the analysis of 158 messages, including postings and comments in the online community of Mumsnet, it can be concluded that informational support and emotional support are the most prevalent types of support women share in the online community. Analysis of data gathered from the survey of 19 women who had experienced a miscarriage during the last year showed that participation in online communities makes a significant improvement in their mental health. Interviews also highlighted the helpful role of the online community in relieving emotional disorders, such as trauma, hopelessness, loneliness, stress, depression and anxiety about miscarriage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title="mental health">mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=miscarriage" title=" miscarriage"> miscarriage</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20community" title=" online community"> online community</a>, <a href="https://publications.waset.org/abstracts/search?q=support" title=" support"> support</a> </p> <a href="https://publications.waset.org/abstracts/172958/potential-positive-impacts-of-online-communities-on-mental-health-of-women-who-have-experienced-miscarriage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172958.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">73</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">12</span> Performance Analysis and Multi-Objective Optimization of a Kalina Cycle for Low-Temperature Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadegh%20Sadeghi">Sadegh Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Shabani"> Negar Shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From a thermal point of view, zeotropic mixtures are likely to be more efficient than azeotropic fluids in low-temperature thermodynamic cycles due to their suitable boiling characteristics. In this study, performance of a low-temperature Kalina cycle with R717/water working fluid used in different existing power plants is mathematically investigated. To analyze the behavior of the cycle, mass conservation, energy conservation, and exergy balance equations are presented. With regard to the similarity in molar mass of R717 (17.03 gr/mol) and water (18.01 gr/mol), there is no need to alter the size of Kalina system components such as turbine and pump. To optimize the cycle energy and exergy efficiencies simultaneously, a constrained multi-objective optimization is carried out applying an Artificial Bee Colony algorithm. The main motivation behind using this algorithm lies on its robustness, reliability, remarkable precision and high–speed convergence rate in dealing with complicated constrained multi-objective problems. Convergence rates of the algorithm for calculating the optimal energy and exergy efficiencies are presented. Subsequently, due to the importance of exergy concept in Kalina cycles, exergy destructions occurring in the components are computed. Finally, the impacts of pressure, temperature, mass fraction and mass flow rate on the energy and exergy efficiencies are elaborately studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20bee%20colony%20algorithm" title="artificial bee colony algorithm">artificial bee colony algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20zeotropic%20mixture" title=" binary zeotropic mixture"> binary zeotropic mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=constrained%20multi-objective%20optimization" title=" constrained multi-objective optimization"> constrained multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20efficiency" title=" exergy efficiency"> exergy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalina%20cycle" title=" Kalina cycle"> Kalina cycle</a> </p> <a href="https://publications.waset.org/abstracts/100534/performance-analysis-and-multi-objective-optimization-of-a-kalina-cycle-for-low-temperature-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100534.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">153</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">11</span> Comparison of Bone Mineral Density of Lumbar Spines between High Level Cyclists and Sedentary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Shabani">Mohammad Shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physical activities depending on the nature of the mechanical stresses they induce on bone sometimes have brought about different results. The purpose of this study was to compare bone mineral density (BMD) of the lumbar spine between the high-level cyclists and sedentary. Materials and Methods: In the present study, 73 cyclists senior (age: 25.81 ± 4.35 years; height: 179.66 ± 6.31 cm; weight: 71.55 ± 6.31 kg) and 32 sedentary subjects (age: 28.28 ± 4.52 years; height: 176.56 ± 6.2 cm; weight: 74.47 ± 8.35 kg) participated voluntarily. All cyclists belonged to the different teams from the International Cycling Union and they trained competitively for 10 years. BMD of the lumbar spine of the subjects was measured using DXA X-ray (Lunar). Descriptive statistics calculations were performed using computer software data processing (Statview 5, SAS Institute Inc. USA). The comparison of two independent distributions (BMD high level cyclists and sedentary) was made by the Student T Test standard. Probability 0.05 (p≤0 / 05) was adopted as significance. Results: The result of this study showed that the BMD values of the lumbar spine of sedentary subjects were significantly higher for all measured segments. Conclusion and Discussion: Cycling is firstly a common sport and on the other hand endurance sport. It is now accepted that weight bearing exercises have an osteogenic effect compared to non-weight bearing exercises. Thus, endurance sports such as cycling, compared to the activities imposing intense force in short time, seem not to really be osteogenic. Therefore, it can be concluded that cycling provides low stimulates osteogenic because of specific biomechanical forces of the sport and its lack of impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BMD" title="BMD">BMD</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20spine" title=" lumbar spine"> lumbar spine</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20level%20cyclist" title=" high level cyclist"> high level cyclist</a>, <a href="https://publications.waset.org/abstracts/search?q=cycling" title=" cycling"> cycling</a> </p> <a href="https://publications.waset.org/abstracts/48671/comparison-of-bone-mineral-density-of-lumbar-spines-between-high-level-cyclists-and-sedentary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48671.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">269</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">10</span> The Effectiveness of Transcranial Electrical Stimulation on Brain Wave Pattern and Blood Pressure in Patients with Generalized Anxiety Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Baghaei">Mahtab Baghaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mahmoud%20Tabatabaei"> Seyed Mahmoud Tabatabaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim & Background: Electrical stimulation of transcranial direct current is considered one of the treatment methods for mental disorders. The aim of this study was to evaluate the effectiveness of transcranial electrical stimulation on the delta, theta, alpha, beta and systolic and diastolic blood pressure in patients with generalized anxiety disorder. Materials and Methods: The present study was a double-blind intervention with a pre-test and post-test design on people with generalized anxiety disorder in Tabriz in 1400. In this study, 30 patients with generalized anxiety disorder were selected by purposive sampling method based on the criteria specified in DSM-5 and randomly divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received two sessions of 30 minutes of electrical stimulation of transcranial direct current with an intensity of 2 mA in the area of the lateral dorsal prefrontal cortex, and the control group also received artificial stimulation. Results: The results showed that transcranial electrical stimulation reduces delta and theta waves and increases beta and alpha brain waves in the experimental group. On the other hand, this method also showed a significant decrease in systolic and diastolic blood pressure in these patients (p <0.01). Conclusion: The results show that transcranial electrical stimulation has a statistically significant effect on brain waves and blood pressure, and this non-invasive method can be used as one of the treatment methods in people with generalized anxiety disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transcranial%20direct%20current%20electrical%20stimulation" title="transcranial direct current electrical stimulation">transcranial direct current electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20waves" title=" brain waves"> brain waves</a>, <a href="https://publications.waset.org/abstracts/search?q=systolic%20blood%20pressure" title=" systolic blood pressure"> systolic blood pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=diastolic%20blood%20pressure" title=" diastolic blood pressure"> diastolic blood pressure</a> </p> <a href="https://publications.waset.org/abstracts/150544/the-effectiveness-of-transcranial-electrical-stimulation-on-brain-wave-pattern-and-blood-pressure-in-patients-with-generalized-anxiety-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150544.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">102</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">9</span> Fenton Sludge's Catalytic Ability with Synergistic Effects During Reuse for Landfill Leachate Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Salim%20Mahtab">Mohd Salim Mahtab</a>, <a href="https://publications.waset.org/abstracts/search?q=Izharul%20Haq%20Farooqi"> Izharul Haq Farooqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Anwar%20Khursheed"> Anwar Khursheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Advanced oxidation processes (AOPs) based on Fenton are versatile options for treating complex wastewaters containing refractory compounds. However, the classical Fenton process (CFP) has limitations, such as high sludge production and reagent dosage, which limit its broad use and result in secondary contamination. As a result, long-term solutions are required for process intensification and the removal of these impediments. This study shows that Fenton sludge could serve as a catalyst in the Fe³⁺/Fe²⁺ reductive pathway, allowing non-regenerated sludge to be reused for complex wastewater treatment, such as landfill leachate treatment, even in the absence of Fenton's reagents. Experiments with and without pH adjustments in stages I and II demonstrated that an acidic pH is desirable. Humic compounds in leachate could improve the cycle of Fe³⁺/Fe²⁺ under optimal conditions, and the chemical oxygen demand (COD) removal efficiency was 22±2% and 62±2%% in stages I and II, respectively. Furthermore, excellent total suspended solids (TSS) removal (> 95%) and color removal (> 80%) were obtained in stage II. The processes underlying synergistic (oxidation/coagulation/adsorption) effects were addressed. The design of the experiment (DOE) is growing increasingly popular and has thus been implemented in the chemical, water, and environmental domains. The relevance of the statistical model for the desired response was validated using the explicitly stated optimal conditions. The operational factors, characteristics of reused sludge, toxicity analysis, cost calculation, and future research objectives were also discussed. Reusing non-regenerated Fenton sludge, according to the study's findings, can minimize hazardous solid toxic emissions and total treatment costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advanced%20oxidation%20processes" title="advanced oxidation processes">advanced oxidation processes</a>, <a href="https://publications.waset.org/abstracts/search?q=catalysis" title=" catalysis"> catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%C2%B3%E2%81%BA%2FFe%C2%B2%E2%81%BA%20cycle" title=" Fe³⁺/Fe²⁺ cycle"> Fe³⁺/Fe²⁺ cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=fenton%20sludge" title=" fenton sludge"> fenton sludge</a> </p> <a href="https://publications.waset.org/abstracts/153862/fenton-sludges-catalytic-ability-with-synergistic-effects-during-reuse-for-landfill-leachate-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153862.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">89</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">8</span> Demographic Impact on Wastewater: A Systemic Analysis of Human Impact on Wastewater Quality in Dhaka, Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dewan%20Hasin%20Mahtab">Dewan Hasin Mahtab</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzana%20Sadia"> Farzana Sadia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At present, wastewater treatment has become essential to maintain a constant supply of safe water as well as to protect the environment. Due to overpopulation and overconsumption, the water quality from various surface water sources is degrading every day. Being one of the megacities in the world, Dhaka City, is going through rapid industrialization and urbanization. The effluents from these industries and factories are mostly discharged directly into the rivers without any treatment. As such, the quality of water of Buriganga is being afflicted with a noisome problem of pollution. The water of the Buriganga River has become detrimental to humans, animals, and the environment. It has become crucial to conserve the environment so that we can save both ourselves and the environment. The first step towards it should be analyzing the wastewater to decide the further steps of the treatment process. Increased population and increased consumption both contribute to water pollution. Mohammadpur is a developing area of Dhaka City, and Kamrangirchar is one of the largest slum areas in Dhaka City. The total study area is 6.13 sq. Km of Dhaka city with a population of 4,73,310 people. Of them, 86.47% had their own latrine, 47% were directly connected to the drain, 55% had septic tanks, and 70.09% of them cleaned their septic tank once a year. The pH, Dissolved Oxygen, Chemical Oxygen Demand, Biochemical Oxygen Demand, Total Dissolved Solid, Total Suspended and total coliforms of wastewater from two samples of both Mohammadpur and Kamrangirchar was analyzed. The DO level from the water bodies of Kamrangirchar was found very low, making the water bodies inhabitable for aquatic plants and animals. The BOD and COD level was extremely high from samples collected from Mohammadpur. The total coliforms count was found too high during the wet season, making it a potential health concern in the wet season in these two areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dhaka" title="Dhaka">Dhaka</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20conservation%20rule" title=" environmental conservation rule"> environmental conservation rule</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/128703/demographic-impact-on-wastewater-a-systemic-analysis-of-human-impact-on-wastewater-quality-in-dhaka-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128703.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">130</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">7</span> Fabrication of Ligand Coated Lipid-Based Nanoparticles for Synergistic Treatment of Autoimmune Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asiya%20Mahtab">Asiya Mahtab</a>, <a href="https://publications.waset.org/abstracts/search?q=Sushama%20Talegaonkar"> Sushama Talegaonkar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research is aimed at developing targeted lipid-based nanocarrier systems of chondroitin sulfate (CS) to deliver an antirheumatic drug to the inflammatory site in arthritic paw. Lipid-based nanoparticle (TEF-lipo) was prepared by using a thin-film hydration method. The coating of prepared drug-loaded nanoparticles was done by the ionic interaction mechanism. TEF-lipo and CS-coated lipid nanoparticle (CS-lipo) were characterized for mean droplet size, zeta potential, and surface morphology. TEF-lipo and CS-lipo were further subjected to in vitro cell line studies on RAW 264.7 murine macrophage, U937, and MG 63 cell lines. The pharmacodynamic study was performed to establish the effectiveness of the prepared lipid-based conventional and targeted nanoparticles in comparison to pure drugs. Droplet size and zeta potential of TEF-lipo were found to be 128. 92 ± 5.42 nm and +12.6 ± 1.2 mV. It was observed that after the coating of TEF-lipo with CS, particle size increased to 155.6± 2.12 nm and zeta potential changed to -10.2± 1.4mV. Transmission electron microscopic analysis revealed that the nanovesicles were uniformly dispersed and detached from each other. Formulations followed sustained release pattern up to 24 h. Results of cell line studies ind icated that CS-lipo formulation showed the highest cytotoxic potential, thereby proving its enhanced ability to kill the RAW 264.7 murine macrophage and U937 cells when compared with other formulations. It is clear from our in vivo pharmacodynamic results that targeted nanocarriers had a higher inhibitory effect on arthritis progression than nontargeted nanocarriers or free drugs. Results demonstrate that this approach will provide effective treatment for rheumatoid arthritis, and CS served as a potential prophylactic against the advancement of cartilage degeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjuvant%20induced%20arthritis" title="adjuvant induced arthritis">adjuvant induced arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=chondroitin%20sulfate" title=" chondroitin sulfate"> chondroitin sulfate</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title=" rheumatoid arthritis"> rheumatoid arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=teriflunomide" title=" teriflunomide"> teriflunomide</a> </p> <a href="https://publications.waset.org/abstracts/116801/fabrication-of-ligand-coated-lipid-based-nanoparticles-for-synergistic-treatment-of-autoimmune-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116801.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">136</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">6</span> Neural Network and Support Vector Machine for Prediction of Foot Disorders Based on Foot Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monireh%20Ahmadi%20Bani">Monireh Ahmadi Bani</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Khorramrouz"> Adel Khorramrouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Lalenoor%20%20Morvarid"> Lalenoor Morvarid</a>, <a href="https://publications.waset.org/abstracts/search?q=Bagheri%20Mahtab"> Bagheri Mahtab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background:- Foot disorders are common in musculoskeletal problems. Plantar pressure distribution measurement is one the most important part of foot disorders diagnosis for quantitative analysis. However, the association of plantar pressure and foot disorders is not clear. With the growth of dataset and machine learning methods, the relationship between foot disorders and plantar pressures can be detected. Significance of the study:- The purpose of this study was to predict the probability of common foot disorders based on peak plantar pressure distribution and center of pressure during walking. Methodologies:- 2323 participants were assessed in a foot therapy clinic between 2015 and 2021. Foot disorders were diagnosed by an experienced physician and then they were asked to walk on a force plate scanner. After the data preprocessing, due to the difference in walking time and foot size, we normalized the samples based on time and foot size. Some of force plate variables were selected as input to a deep neural network (DNN), and the probability of any each foot disorder was measured. In next step, we used support vector machine (SVM) and run dataset for each foot disorder (classification of yes or no). We compared DNN and SVM for foot disorders prediction based on plantar pressure distributions and center of pressure. Findings:- The results demonstrated that the accuracy of deep learning architecture is sufficient for most clinical and research applications in the study population. In addition, the SVM approach has more accuracy for predictions, enabling applications for foot disorders diagnosis. The detection accuracy was 71% by the deep learning algorithm and 78% by the SVM algorithm. Moreover, when we worked with peak plantar pressure distribution, it was more accurate than center of pressure dataset. Conclusion:- Both algorithms- deep learning and SVM will help therapist and patients to improve the data pool and enhance foot disorders prediction with less expense and error after removing some restrictions properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20neural%20network" title="deep neural network">deep neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=foot%20disorder" title=" foot disorder"> foot disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=plantar%20pressure" title=" plantar pressure"> plantar pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/139369/neural-network-and-support-vector-machine-for-prediction-of-foot-disorders-based-on-foot-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139369.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">358</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> Numerical Analysis of the Response of Thin Flexible Membranes to Free Surface Water Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Makaremi%20Masouleh">Mahtab Makaremi Masouleh</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnter%20Wozniak"> Günter Wozniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is part of a major research project concerning the design of a light temporary installable textile flood control structure. The motivation for this work is the great need of applying light structures for the protection of coastal areas from detrimental effects of rapid water runoff. The prime objective of the study is the numerical analysis of the interaction among free surface water flow and slender shaped pliable structures, playing a key role in safety performance of the intended system. First, the behavior of down scale membrane is examined under hydrostatic pressure by the Abaqus explicit solver, which is part of the finite element based commercially available SIMULIA software. Then the procedure to achieve a stable and convergent solution for strongly coupled media including fluids and structures is explained. A partitioned strategy is imposed to make both structures and fluids be discretized and solved with appropriate formulations and solvers. In this regard, finite element method is again selected to analyze the structural domain. Moreover, computational fluid dynamics algorithms are introduced for solutions in flow domains by means of a commercial package of Star CCM+. Likewise, SIMULIA co-simulation engine and an implicit coupling algorithm, which are available communication tools in commercial package of the Star CCM+, enable powerful transmission of data between two applied codes. This approach is discussed for two different cases and compared with available experimental records. In one case, the down scale membrane interacts with open channel flow, where the flow velocity increases with time. The second case illustrates, how the full scale flexible flood barrier behaves when a massive flotsam is accelerated towards it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20formulation" title="finite element formulation">finite element formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20volume%20algorithm" title=" finite volume algorithm"> finite volume algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid-structure%20interaction" title=" fluid-structure interaction"> fluid-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20pliable%20structure" title=" light pliable structure"> light pliable structure</a>, <a href="https://publications.waset.org/abstracts/search?q=VOF%20multiphase%20model" title=" VOF multiphase model"> VOF multiphase model</a> </p> <a href="https://publications.waset.org/abstracts/78889/numerical-analysis-of-the-response-of-thin-flexible-membranes-to-free-surface-water-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78889.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">186</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> Transvaginal Repair of Anterior Vaginal Wall Prolapse with Polyvinylidene Fluoride (PVDF) Mesh: An Alternative for Previously Restricted Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad-Javad%20Eslami">Mohammad-Javad Eslami</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Zargham"> Mahtab Zargham</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshad%20Gholipour"> Farshad Gholipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Hajian"> Mohammadreza Hajian</a>, <a href="https://publications.waset.org/abstracts/search?q=Katayoun%20Bakhtiari"> Katayoun Bakhtiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakineh%20Hajebrahimi"> Sakineh Hajebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Melina%20Eghbal"> Melina Eghbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziba%20Farajzadegan"> Ziba Farajzadegan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: To study the mid-term safety and functional outcomes of transvaginal anterior vaginal wall prolapse repair using polyvinylidene fluoride (PVDF) mesh (DynaMesh®-PR4) by the double trans-obturator technique (TOT). Methods: Between 2015 and 2020, we prospectively included women with symptomatic high-stage anterior vaginal wall prolapse with or without uterine prolapse or stress urinary incontinence (SUI) in the study. The patients underwent transvaginal repair of the prolapse using PVDF mesh in two medical centers. We followed all patients for at least 12 months. We recorded the characteristics of vaginal and sexual symptoms, urinary incontinence, and prolapse stage pre- and postoperatively using International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS), International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF), and Pelvic Organ Prolapse Quantification (POP-Q) system, respectively. Results: One hundred eight women were included in the final analysis with a mean follow-up time of 34.5 ± 18.6 months. The anatomical success was achieved in 103 (95.4%) patients. There was a significant improvement in patients’ vaginal symptoms, urinary incontinence, and quality of life scores postoperatively (p < 0.0001). Only six patients (5.5%) had mesh extrusion, five of whom were managed successfully. The total rates of complications and de novo urinary symptoms were 21.3% and 7.4%, respectively. Significant pain was reported in 17 cases (15.7%). Conclusion: Our findings show that using PVDF mesh in the double TOT technique for anterior vaginal wall prolapse repair is a safe procedure with high anatomic and functional success rates and acceptable complication rates in mid-term follow-up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress%20urinary%20incontinence%20%28SU" title="stress urinary incontinence (SU">stress urinary incontinence (SU</a>, <a href="https://publications.waset.org/abstracts/search?q=incontinence%20questionnaire-vaginal%20symptoms%20%28ICIQ-VS%29" title=" incontinence questionnaire-vaginal symptoms (ICIQ-VS)"> incontinence questionnaire-vaginal symptoms (ICIQ-VS)</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinylidene%20fluoride%20%28PVDF%29%20mes" title=" polyvinylidene fluoride (PVDF) mes"> polyvinylidene fluoride (PVDF) mes</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20trans-obturator%20technique%20%28TOT%29" title=" double trans-obturator technique (TOT)"> double trans-obturator technique (TOT)</a> </p> <a href="https://publications.waset.org/abstracts/187036/transvaginal-repair-of-anterior-vaginal-wall-prolapse-with-polyvinylidene-fluoride-pvdf-mesh-an-alternative-for-previously-restricted-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187036.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">46</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> Development of an Implicit Coupled Partitioned Model for the Prediction of the Behavior of a Flexible Slender Shaped Membrane in Interaction with Free Surface Flow under the Influence of a Moving Flotsam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Makaremi%20Masouleh">Mahtab Makaremi Masouleh</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnter%20Wozniak"> Günter Wozniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research is part of an interdisciplinary project, promoting the design of a light temporary installable textile defence system against flood. In case river water levels increase abruptly especially in winter time, one can expect massive extra load on a textile protective structure in term of impact as a result of floating debris and even tree trunks. Estimation of this impulsive force on such structures is of a great importance, as it can ensure the reliability of the design in critical cases. This fact provides the motivation for the numerical analysis of a fluid structure interaction application, comprising flexible slender shaped and free-surface water flow, where an accelerated heavy flotsam tends to approach the membrane. In this context, the analysis on both the behavior of the flexible membrane and its interaction with moving flotsam is conducted by finite elements based solvers of the explicit solver and implicit Abacus solver available as products of SIMULIA software. On the other hand, a study on how free surface water flow behaves in response to moving structures, has been investigated using the finite volume solver of Star CCM+ from Siemens PLM Software. An automatic communication tool (CSE, SIMULIA Co-Simulation Engine) and the implementation of an effective partitioned strategy in form of an implicit coupling algorithm makes it possible for partitioned domains to be interconnected powerfully. The applied procedure ensures stability and convergence in the solution of these complicated issues, albeit with high computational cost; however, the other complexity of this study stems from mesh criterion in the fluid domain, where the two structures approach each other. This contribution presents the approaches for the establishment of a convergent numerical solution and compares the results with experimental findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-simulation" title="co-simulation">co-simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20thin%20structure" title=" flexible thin structure"> flexible thin structure</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid-structure%20interaction" title=" fluid-structure interaction"> fluid-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=implicit%20coupling%20algorithm" title=" implicit coupling algorithm"> implicit coupling algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20flotsam" title=" moving flotsam"> moving flotsam</a> </p> <a href="https://publications.waset.org/abstracts/78832/development-of-an-implicit-coupled-partitioned-model-for-the-prediction-of-the-behavior-of-a-flexible-slender-shaped-membrane-in-interaction-with-free-surface-flow-under-the-influence-of-a-moving-flotsam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78832.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">389</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> Code-Switching as a Bilingual Phenomenon among Students in Prishtina International Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Festa%20Shabani">Festa Shabani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at investigating bilingual speech in the International Schools of Prishtina. More particularly, it seeks to analyze bilingual phenomena among adolescent students highly exposed to English with the latter as the language of instruction at school in naturally-occurring conversations within school environment. Adolescence was deliberately chosen since it is regarded as an age when peer influence on language choice is the greatest. Driven by daily unsystematic observation and prior research already undertaken, the hypothesis stated is that Albanian continues to be the dominant language among Prishtina international schools’ students with a lot of code-switched items from the English. Furthermore, they will also use lexical borrowings - words already adapted in the receiving language, from the language they have been in contact with, in their speech often in the lack of existing equivalents in Albanian or for other reasons. This is done owing to the fact that the language of instruction at school is English, and any topic related to the language they have been exposed to will trigger them to use English. Therefore, this needs special attention in an attempt to identify patterns of their speech; in this way, linguistic and socio-pragmatic factors will be considered when analyzing the motivations behind their language choice. Methodology for collecting data include participant systematic observation and tape-recording. While observing them in their natural conversations, the fieldworker also took notes, which helped transcribe details better. The paper starts by raising the question of whether code-switching is occurring among Prishtina International Schools’ students highly exposed to English. The data gathered from students in informal settings suggests that there are well-founded grounds for an affirmative answer. The participants in this study are observed to be code-switching, although showing differences in degree. However, a generalization cannot be made on the basis of the findings except in so far it appears that English has, in turn, became a language to which they turn when identifying with the group when discussing about particular school topics. Particularly, participants seemed to use intra-sentential CS in cases when they seem to find an English expression rather easier than an Albanian one when repeating or emphasizing a point when urged to talk about educational issues with English being their language of instruction, and inter-sentential code-switching, particularly when quoting others. Concerning the grammatical aspect of code-switching, the intrasentential CS is used more than the intersentetial one. Speaking of gender, the results show that there were really no significant differences in regards quantity between male and female participants. However, the slight tendency for men to code switch intrasententially more than women was manifested. Similarly, a slight tendency again for a difference to emerge is on intersentential switching, which contributes 21% to the total number of switches for women, but 11% to the total number of switches for men. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Albanian" title="Albanian">Albanian</a>, <a
