Aim: This study aimed to assess the perception and attitude of pharmacists in oral health promotion and to determine the confident levels of pharmacists in delivering advice on oral health problems. Methods: An observational cross-sectional survey, using self-administered anonymous questionnaires, was conducted between March and April 2017. The study recruited a convenience sample of registered community pharmacists who were working in local private pharmaceutical stores in the urban area of Madinah, Kingdom of Saudi Arabia (KSA). A preliminary descriptive analysis was performed. Results: Thirty-five pharmacists have completed the surveys. All participants were males, with a mean age of 35.5 ( ± 6.92) years. Eighty-six percent of the participants reported that pharmacists should have a role in oral health promotion. Eighty percent have reported adequate level of confident when giving advice on most of the common oral health problems that include; oral health related risk behaviors such as tobacco cessation (46%), bleeding gums (63%) and sensitive teeth (60%). However, higher percentages of pharmacists have reported low confident levels when giving advice in relation to specific domain of dentistry, such as lost dental fillings (57%), loose crowns (60%), trauma to teeth (40%), denture-related problems (51%) and oral cancer (6.9%). Conclusion: Community pharmacists recognized their potential role in promoting oral health in KSA. Community pharmacists had varying levels of ability and confidence to offer support for oral health. The study highlighted that inner professional collaboration between pharmacists and dental care healthcare should be enhanced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20health" title=" oral health"> oral health</a>, <a href="https://publications.waset.org/abstracts/search?q=promotion" title=" promotion"> promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacist" title=" pharmacist"> pharmacist</a> </p> <a href="https://publications.waset.org/abstracts/84196/community-pharmacists-perceptions-attitude-and-role-in-oral-health-promotion-and-diseases-prevention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84196.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">197</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">36</span> Evaluation of Hydrocarbons in Tissues of Bivalve Mollusks from the Red Sea Coast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Ahmed%20Aljohani">Asma Ahmed Aljohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Orif"> Mohammed Orif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concentration of polycyclic aromatic hydrocarbons (PAH) in clam (A. glabrata) was examined in samples collected from Alseef Beach, 30 km south of Jeddah city.

Its value creates chances for users to profit from data sales and purchases. Users in data marketplaces, however, must share and trade data in a secure and trusted environment while maintaining their privacy. The first main contribution of this paper is to identify enabling technologies and challenges facing the development of decentralized data marketplaces. The second main contribution is to propose a decentralized data marketplace framework based on blockchain technology. The proposed framework enables sellers and buyers to transact with more confidence. Using a security deposit, the system implements a unique approach for enforcing honesty in data exchange among anonymous individuals. Before the transaction is considered complete, the system has a time frame. As a result, users can submit disputes to the arbitrators which will review them and respond with their decision. Use cases are presented to demonstrate how these technologies help data marketplaces handle issues and challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=data" title=" data"> data</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20marketplace" title=" data marketplace"> data marketplace</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20contract" title=" smart contract"> smart contract</a>, <a href="https://publications.waset.org/abstracts/search?q=reputation%20system" title=" reputation system"> reputation system</a> </p> <a href="https://publications.waset.org/abstracts/149122/decentralized-data-marketplace-framework-using-blockchain-based-smart-contract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149122.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">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Description of Geotechnical Properties of Jabal Omar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Abdel%20Gadir%20Malik">Ibrahim Abdel Gadir Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=Dafalla%20Siddig%20Dafalla"> Dafalla Siddig Dafalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Abdelgadir%20El-Bushra"> Osama Abdelgadir El-Bushra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Geological and engineering characteristics of intact rock and the discontinuity surfaces was used to describe and classify rock mass into zones based on mechanical and physical properties.

Language also represents a recording device whereby they capture the transient moment in their lives. Literature with it its various manifestations help keep the individual and collective memories alive. Works of the English literature’s prototypical figure, William Shakespeare provides the best illustration of this fact. Shakespeare’s sonnets abound in prescient insights about the intricacies of human relations. Though they have been the concern of scholars’ investigations for centuries, many of their thematic potentialities are yet to be tapped. The present study aspires to highlight the theme of remembering and forgetting in some of these sonnets as reverse faces of the same coin. Using close reading it is intended to demonstrate how Shakespeare, through imagery and literary tropes, plays with the issues of mortality and immortality, and how he has reaffirmed that literature can provide a locus for perennial presence despite the temporariness of individuals’ existence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forgetting" title="forgetting">forgetting</a>, <a href="https://publications.waset.org/abstracts/search?q=immortality" title=" immortality"> immortality</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=remembering" title=" remembering"> remembering</a>, <a href="https://publications.waset.org/abstracts/search?q=Shakespeare" title=" Shakespeare"> Shakespeare</a>, <a href="https://publications.waset.org/abstracts/search?q=sonnet" title=" sonnet"> sonnet</a> </p> <a href="https://publications.waset.org/abstracts/38356/remembering-and-forgetting-in-shakespeare-sonnets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38356.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">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> A Framework for Analyzing Public Interaction of Saudi Universities on Twitter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Al-Qahtani">Sahar Al-Qahtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabeeh%20Ayaz%20Abbasi"> Rabeeh Ayaz Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Naif%20Radi%20Aljohani"> Naif Radi Aljohani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many universities use social media platforms as new communication channels to disseminate information and promptly communicate with their audience. As Twitter is one of the widely used social media platforms, this research aims to explore the adaption and utilization of Twitter by universities. We propose a framework called 'Social Network Analysis for Universities on Twitter' (SNAUT) to analyze the usage of Twitter by universities and to measure their interaction with public. The study includes a sample of around 110,000 tweets from 36 Saudi universities, including both public and private universities. Using SNAUT, we can (1) investigate the purpose of using Twitter by universities, (2) determine the broad topics discussed by them, and (3) identify the groups closely associated with the universities. The results show that most of the Saudi universities (whether public or private) actively use Twitter. Results also reveal that public universities respond to public queries more frequently, but private universities stand out more in terms of information dissemination using retweets and diverse hashtags. Finally, we develop a ranking mechanism in SNAUT for ranking universities based on their social interaction with the public on Twitter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20media" title="social media">social media</a>, <a href="https://publications.waset.org/abstracts/search?q=twitter" title=" twitter"> twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20network%20analysis" title=" social network analysis"> social network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=universities" title=" universities"> universities</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/121965/a-framework-for-analyzing-public-interaction-of-saudi-universities-on-twitter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121965.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">31</span> Adopting Circular Economy Principles in Municipal Waste Management: A Pathway to Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra">Bushra</a>, <a href="https://publications.waset.org/abstracts/search?q=Filza%20Akhtar"> Filza Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As countries face increased pressure to address environmental issues and resource constraints, the need to implement sustainable waste management strategies grows. This research study investigates the concept of circular economy principles in the context of municipal waste management as a tool for achieving sustainability goals. Municipalities can reduce environmental impacts, conserve resources, and promote economic development by switching from traditional linear waste disposal prototypes to circular approaches prioritizing waste minimization, reuse, recycling, and resource recovery. Drawing on case studies and best practices worldwide, this study investigates the potential benefits, obstacles, and opportunities of incorporating circular economy principles into waste management methods.

However, apart from academics, stress springs from various other sources namely, finance, family, health, friends etc. The present study aims to assess the level of perceived stress in medical and fine arts students, and to determine the coping strategies used by the students to mitigate stress. The sample of the study consisted of 178 medical and fine arts students. The sample was selected through purposive sampling. Pearson correlation coefficient and T-test were used to analyze data. Results of the study revealed that there exists a positive relationship between perceived stress and coping strategies. Additionally, the two groups showed marked differences in terms of stress perception and coping styles. The level of perceived stress was found to be high in medical students nonetheless, they employed more positive coping strategies than fine arts students who scored high on negative coping strategies which are deleterious to the overall wellbeing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perceived%20stress" title="perceived stress">perceived stress</a>, <a href="https://publications.waset.org/abstracts/search?q=coping%20strategies" title=" coping strategies"> coping strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=medical" title=" medical"> medical</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20arts%20students" title=" fine arts students"> fine arts students</a> </p> <a href="https://publications.waset.org/abstracts/52648/comparative-study-of-medical-and-fine-art-students-on-the-level-of-perceived-stress-and-coping-skills" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52648.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">307</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> Indigenous Patch Clamp Technique: Design of Highly Sensitive Amplifier Circuit for Measuring and Monitoring of Real Time Ultra Low Ionic Current through Cellular Gates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moez%20ul%20Hassan">Moez ul Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Noman"> Bushra Noman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarmad%20Hameed"> Sarmad Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahab%20Mehmood"> Shahab Mehmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Bashir"> Asma Bashir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of Noble prize winning “Patch Clamp Technique” is well documented. However, Patch Clamp Technique is very expensive and hence hinders research in developing countries. In this paper, detection, processing and recording of ultra low current from induced cells by using transimpedence amplifier is described. The sensitivity of the proposed amplifier is in the range of femto amperes (fA). Capacitive-feedback is used with active load to obtain a 20MΩ transimpedance gain. The challenging task in designing includes achieving adequate performance in gain, noise immunity and stability. The circuit designed by the authors was able to measure current in the rangeof 300fA to 100pA. Adequate performance shown by the amplifier with different input current and outcome result was found to be within the acceptable error range. Results were recorded using LabVIEW 8.5®for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title="drug discovery">drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20current" title=" ionic current"> ionic current</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20amplifier" title=" operational amplifier"> operational amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20clamp" title=" patch clamp"> patch clamp</a> </p> <a href="https://publications.waset.org/abstracts/28042/indigenous-patch-clamp-technique-design-of-highly-sensitive-amplifier-circuit-for-measuring-and-monitoring-of-real-time-ultra-low-ionic-current-through-cellular-gates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28042.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">519</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> Preparation of Hyperbranched Polymers for Application in Light Emitting Diodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amal%20Aljohani">Amal Aljohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Iraqi"> Ahmed Iraqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emitting materials with thermally activated delayed fluorescence (TADF) properties as the third generation of organic light-emitting diodes (OLEDs) have received much attention as a modern class of highly efficient emitters because such properties enable the harvesting of both singlet and triplet excitons in EL applications without the doping with complexes of scarce noble metals such as platinum and iridium. Improved molecular design of TADF molecules and applied materials exhibiting internal electroluminescence (EL) with quantum efficiencies of nearly 100% has been achieved being. A2B3 hyperbranched polymers based on new derivatives containing silane core units serving as host materials for thermally activated delayed fluorescence (TADF) guest molecules have been designed and synthesized through several steps, including the synthesis of tetrakis(4-bromophenyl)silane, bis(4-(9H-carbazol-9-yl)phenyl)bis(4-bromophenyl)silane,bis(4-(9H-carbazol-9 yl)phenyl)bis(4-methoxyphenyl)silane and bis(4-(9H-carbazol-9-yl)phenyl)bis(4hydroxyphenyl)silane. This monomer has been used successfully used along with 1,1,1-tri-(p-tosyloxymethyl)-propane to prepare A2B3 hyperbranched polymers via step-growth polymerization.

Personas are used to represent end users’ needs. In our research, creating personas allowed the following questions to be answered: Who are the potential user groups? What do they want to achieve by using the service? What are the problems that users face? What should the service provide to them? To develop realistic personas, we conducted a focus group discussion with undergraduate and graduate students and also interviewed a university librarian. The personas were created to help evaluating the Institutional Repository that is based on the DSpace system. The profiles helped to communicate users' needs, abilities, tasks, and problems, and the task scenarios used in the heuristic evaluation were based on these personas. Four personas resulted of a focus group discussion with undergraduate and graduate students and from interviewing a university librarian. We then used these personas to create focused task-scenarios for a heuristic evaluation on the system interface to ensure that it met users' needs, goals, problems and desires. In this paper, we present the process that we used to create the personas that led to devise the task scenarios used in the heuristic evaluation as a follow up study of the DSpace university repository. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heuristic%20evaluation" title="heuristic evaluation">heuristic evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20repositories" title=" institutional repositories"> institutional repositories</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20experience" title=" user experience"> user experience</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title=" human computer interaction"> human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20profiles" title=" user profiles"> user profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=personas" title=" personas"> personas</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20scenarios" title=" task scenarios"> task scenarios</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristics" title=" heuristics"> heuristics</a> </p> <a href="https://publications.waset.org/abstracts/13758/personas-help-understand-users-needs-goals-and-desires-in-an-online-institutional-repository" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13758.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">499</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">26</span> A Systematic Literature Review on Security and Privacy Design Patterns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebtehal%20Aljedaani">Ebtehal Aljedaani</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Aljohani"> Maha Aljohani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Privacy and security patterns are both important for developing software that protects users' data and privacy. Privacy patterns are designed to address common privacy problems, such as unauthorized data collection and disclosure. Security patterns are designed to protect software from attack and ensure reliability and trustworthiness. Using privacy and security patterns, software engineers can implement security and privacy by design principles, which means that security and privacy are considered throughout the software development process. These patterns are available to translate "security & privacy-by-design" into practical advice for software engineering. Previous research on privacy and security patterns has typically focused on one category of patterns at a time. This paper aims to bridge this gap by merging the two categories and identifying their similarities and differences. To do this, the authors conducted a systematic literature review of 25 research papers on privacy and security patterns. The papers were analysed based on the category of the pattern, the classification of the pattern, and the security requirements that the pattern addresses. This paper presents the results of a comprehensive review of privacy and security design patterns. The review is intended to help future IT designers understand the relationship between the two types of patterns and how to use them to design secure and privacy-preserving software. The paper provides a clear classification of privacy and security design patterns, along with examples of each type. The authors found that there is only one widely accepted classification of privacy design patterns, while there are several competing classifications of security design patterns. Three types of security design patterns were found to be the most commonly used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20patterns" title="design patterns">design patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy" title=" privacy"> privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=classification%20of%20patterns" title=" classification of patterns"> classification of patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20patterns" title=" security patterns"> security patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy%20patterns" title=" privacy patterns"> privacy patterns</a> </p> <a href="https://publications.waset.org/abstracts/174494/a-systematic-literature-review-on-security-and-privacy-design-patterns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174494.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">132</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> Wetting-Drying Cycles Effect on Piles Embedded in a Very High Expansive Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Suhail">Bushra Suhail</a>, <a href="https://publications.waset.org/abstracts/search?q=Laith%20Kadim"> Laith Kadim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The behavior of model piles embedded in a very high expansive soil was investigated, a specially manufactured saturation-drying tank was used to apply three cycles of wetting and drying to the expansive soil surrounding the model straight shaft and under reamed piles, the relative movement of the piles with respect to the soil surface was recorded with time, also the exerted uplift pressure of the piles due to soil swelling was recorded.

All the tested essential oils, in different concentrations, inhibited growth of S. aureus to varying degrees. Cinnamon and Thyme essential oils were observed to be the “best” against test pathogen. Even at lowest concentration of these essential oils i.e. 25 µl/ml, clear zone of inhibition was recorded 9+0.085mm and 8+0.051mm respectively, and at higher concentrations there was a total reduction in growth of MRSA. The study also focused on analyzing the synergistic effects of essential oils in combination with amoxicillin. Results showed that oregano and pennyroyal mint essential oils which were not very effective alone turned out to be strong synergistic enhancers. The activity increased with increase in concentration of the essential oils.

Different chemical cues help to correspond in the diversity of associations between prey and host plant species. Coccinellaseptempunctata and Diaeretiellarapae have the abilities to explore several chemical cues released by plants under herbivore attack that may enhance their efficiency of foraging. In this study, the behavioral responses of Coccinellaseptempunctata and Diaeretiellarapae were examined under the application of two semiochemicals and a plant extract and their combinations using four-arm olfactometer. The bioassay was consists of a pairwise treatment comparison. Data pertaining to the preference of C. septempunctata and D. rapae after treatment application were recorded and analyzed statistically. The mean number of entries and time spent of Coccinellaseptempunctata and D. rapaewere greater in arms treated with E-β-Farnesene. However, the efficacy of E-β-Farnesene was enhanced when combined with β-pinene. Thus, the mean number of entries and time spent of C. septempunctata and D. rapaewere highest in arms treated with the combination of E-β-Farnesene x β-pinene as compared with other treatments. The current work has demonstrated that the insect-derived semiochemicals may enhance the efficacy of natural enemies when applied in combination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olfectometer" title="olfectometer">olfectometer</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitoid" title=" parasitoid"> parasitoid</a>, <a href="https://publications.waset.org/abstracts/search?q=predator" title=" predator"> predator</a>, <a href="https://publications.waset.org/abstracts/search?q=preference" title=" preference"> preference</a> </p> <a href="https://publications.waset.org/abstracts/99046/behavioral-responses-of-coccinella-septempunctata-and-diaeretiella-rapae-toward-semiochemicals-and-plant-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99046.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">145</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">22</span> Development of Lipid Architectonics for Improving Efficacy and Ameliorating the Oral Bioavailability of Elvitegravir </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Nabi">Bushra Nabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleha%20Rehman"> Saleha Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjula%20Baboota"> Sanjula Baboota</a>, <a href="https://publications.waset.org/abstracts/search?q=Javed%20Ali"> Javed Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: The objective of research undertaken is analytical method validation (HPLC method) of an anti-HIV drug Elvitegravir (EVG).

The significance of the current research project lies in its contribution to determining the usefulness of synchronous technology-mediated interactive group discussion in improving different speaking strategies through using synchronous technology. Also, it discovers how to optimize learning outcomes, expand evaluation for online learning tasks and engaging students’ experience in evaluating synchronous interactive tools and tasks. The researcher used SpeakApps, a synchronous technology, that allows the students to practice oral interaction outside the classroom. Such a course of action was considered necessary due to low English proficiency among Saudi students. According to the author's knowledge, the main factor that causes poor speaking skills is that students do not have sufficient time to communicate outside English language classes. Further, speaking and listening course contents are not well designed to match the Saudi learning context. The methodology included designing speaking tasks to match the educational setting; a CALL framework for designing and evaluating tasks; participant involvement in evaluating these tasks in each online session; and an investigation of the factors that led to the successful implementation of Task-based Language Teaching (TBLT) and using SpeakApps. The analysis and data were drawn from the technology acceptance model surveys, a group interview, teachers’ and students’ weekly reflections, and discourse analysis of students’ interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CALL%20evaluation" title="CALL evaluation">CALL evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous%20technology" title=" synchronous technology"> synchronous technology</a>, <a href="https://publications.waset.org/abstracts/search?q=speaking%20skill" title=" speaking skill"> speaking skill</a>, <a href="https://publications.waset.org/abstracts/search?q=task-based%20language%20teaching" title=" task-based language teaching"> task-based language teaching</a> </p> <a href="https://publications.waset.org/abstracts/62071/an-investigation-of-the-integration-of-synchronous-online-tools-into-task-based-language-teaching-the-example-of-speakapps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62071.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">310</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> Author Profiling: Prediction of Learners’ Gender on a MOOC Platform Based on Learners’ Comments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahani%20Aljohani">Tahani Aljohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jialin%20Yu"> Jialin Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra.%20I.%20Cristea"> Alexandra.

Especially in the booming realm of MOOC Massive Online Learning platforms, only a very low percentage of users disclose demographic information about themselves. Thus, in this paper, we aim to predict learners’ demographic characteristics, by proposing an approach using linguistically motivated Deep Learning Architectures for Learner Profiling, particularly targeting gender prediction on a FutureLearn MOOC platform. Additionally, we tackle here the difficult problem of predicting the gender of learners based on their comments only – which are often available across MOOCs. The most common current approaches to text classification use the Long Short-Term Memory (LSTM) model, considering sentences as sequences. However, human language also has structures. In this research, rather than considering sentences as plain sequences, we hypothesise that higher semantic - and syntactic level sentence processing based on linguistics will render a richer representation. We thus evaluate, the traditional LSTM versus other bleeding edge models, which take into account syntactic structure, such as tree-structured LSTM, Stack-augmented Parser-Interpreter Neural Network (SPINN) and the Structure-Aware Tag Augmented model (SATA). Additionally, we explore using different word-level encoding functions. We have implemented these methods on Our MOOC dataset, which is the most performant one comparing with a public dataset on sentiment analysis that is further used as a cross-examining for the models' results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20predication" title=" gender predication"> gender predication</a>, <a href="https://publications.waset.org/abstracts/search?q=MOOCs" title=" MOOCs"> MOOCs</a> </p> <a href="https://publications.waset.org/abstracts/114514/author-profiling-prediction-of-learners-gender-on-a-mooc-platform-based-on-learners-comments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114514.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">148</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">19</span> Cost Overrun in Delivery of Public Projects in the Saudi Construction Industry: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Aljohani">A.

It occurs irrespective of type and size of the project, its location, procurement method or client. The size of overruns can be as high as 200% in some cases. Projects thus unfortunately often make the news headlines, not for their immense socio-economic contribution to society, but for being poorly procured. In Saudi Arabia, two-thirds of construction projects are publicly procured by the Saudi government, which has been invested Billions of dollars in infrastructure projects each year as part of an ambitious strategic development agenda to shift from mainly oil dependency to multi-source dependency. However, reports show that about 3,000 public projects face diverse issues related to time and cost overrun. As part of an on-going study to develop a framework for effective public procurement for the Saudi Arabian construction industry, this paper reports the initial findings of the causes of cost overruns in the context of the Gulf State. It also evaluates the interface between some of the front-end loading issues in public procurement in Saudi and their effects on project performance. A systematic review of the existing literature on construction cost overruns, with focus on the Saudi Arabian construction industry has been used. One of the initial findings is that a fixed-price contract is usually used by the client in an attempt to transfer all financial risks to the contractors. This has the unintended consequence of creating a turbulent environment for the delivery of the project which leads to project abandonment by contractors, poor quality of work and substantial rework. Further work is being undertaken to empirically verify the initial findings reported in this paper and their generalizability for the construction industry as a whole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost%20overrun" title="cost overrun">cost overrun</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20procurement" title=" public procurement"> public procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20projects" title=" construction projects"> construction projects</a> </p> <a href="https://publications.waset.org/abstracts/38048/cost-overrun-in-delivery-of-public-projects-in-the-saudi-construction-industry-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38048.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">270</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> Machine Learning Techniques for COVID-19 Detection: A Comparative Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abeer%20A.%20Aljohani">Abeer A.

It is also referred to as coronavirus, which is a contagious disease that continuously mutates into numerous variants. Currently, the B.1.1.529 variant labeled as omicron is detected in South Africa. The huge spread of COVID-19 disease has affected several lives and has surged exceptional pressure on the healthcare systems worldwide. Also, everyday life and the global economy have been at stake. This research aims to predict COVID-19 disease in its initial stage to reduce the death count. Machine learning (ML) is nowadays used in almost every area. Numerous COVID-19 cases have produced a huge burden on the hospitals as well as health workers. To reduce this burden, this paper predicts COVID-19 disease is based on the symptoms and medical history of the patient. This research presents a unique architecture for COVID-19 detection using ML techniques integrated with feature dimensionality reduction. This paper uses a standard UCI dataset for predicting COVID-19 disease. This dataset comprises symptoms of 5434 patients. This paper also compares several supervised ML techniques to the presented architecture. The architecture has also utilized 10-fold cross validation process for generalization and the principal component analysis (PCA) technique for feature reduction. Standard parameters are used to evaluate the proposed architecture including F1-Score, precision, accuracy, recall, receiver operating characteristic (ROC), and area under curve (AUC). The results depict that decision tree, random forest, and neural networks outperform all other state-of-the-art ML techniques. This achieved result can help effectively in identifying COVID-19 infection cases. <p class="card-text"><strong>Keywords:</strong> <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=COVID-19%20prediction" title=" COVID-19 prediction"> COVID-19 prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20analytics" title=" healthcare analytics"> healthcare analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/145315/machine-learning-techniques-for-covid-19-detection-a-comparative-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145315.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">17</span> Validation of the Recovery of House Dust Mites from Fabrics by Means of Vacuum Sampling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Aljohani">A.

Vacuum sampling is commonly used to recover and determine the abundance of HDMs but the efficiency of this method is less than standardized. Here, the efficiency of recovery of HDMs was evaluated from home-associated textiles using vacuum sampling protocols.Methods/Approach: Living Mites (LMs) or dead Mites (DMs) House Dust Mites (Dermatophagoides pteronyssinus: FERA, UK) were separately seeded onto the surfaces of Smooth Cotton, Denim and Fleece (25 mites/10x10cm2 squares) and left for 10 minutes before vacuuming. Fabrics were vacuumed (SKC Flite 2 pump) at a flow rate of 14 L/min for 60, 90 or 120 seconds and the number of mites retained by the filter (0.4μm x 37mm) unit was determined. Vacuuming was carried out in a linear direction (Protocol 1) or in a multidirectional pattern (Protocol 2). Additional fabrics with LMs were also frozen and then thawed, thereby euthanizing live mites (now termed EMs). Results/Findings: While there was significantly greater (p=0.000) recovery of mites (76% greater) in fabrics seeded with DMs than LMs irrespective of vacuuming protocol or fabric type, the efficiency of recovery of DMs (72%-76%) did not vary significantly between fabrics. For fabrics containing EMs, recovery was greatest for Smooth Cotton and Denim (65-73% recovered) and least for Fleece (15% recovered). There was no significant difference (p=0.99) between the recovery of mites across all three mite categories from Smooth Cotton and Denim but significantly fewer (p=0.000) mites were recovered from Fleece. Scanning Electron Microscopy images of HMD-seeded fabrics showed that live mites burrowed deeply into the Fleece weave which reduced their efficiency of recovery by vacuuming. Research Implications: Results presented here have implications for the recovery of HDMs by vacuuming and the choice of fabric to ameliorate HDM-dust sensitization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergy" title="allergy">allergy</a>, <a href="https://publications.waset.org/abstracts/search?q=asthma" title=" asthma"> asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=dead" title=" dead"> dead</a>, <a href="https://publications.waset.org/abstracts/search?q=fabric" title=" fabric"> fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=fleece" title=" fleece"> fleece</a>, <a href="https://publications.waset.org/abstracts/search?q=live%20mites" title=" live mites"> live mites</a>, <a href="https://publications.waset.org/abstracts/search?q=sampling" title=" sampling"> sampling</a> </p> <a href="https://publications.waset.org/abstracts/138649/validation-of-the-recovery-of-house-dust-mites-from-fabrics-by-means-of-vacuum-sampling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138649.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">139</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">16</span> Resilience among Children with and without Hearing Loss: A Comparative Study in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Akram">Bushra Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Tariq"> Amina Tariq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This cross-sectional descriptive study aimed to compare the level of resilience among children with and without hearing loss. Methodology: In this descriptive cross sectional study total 500 children (with hearing loss = 250 and without hearing loss = 250) were recruited conveniently. Children with hearing loss were recruited from the special schools whereas children without hearing loss were selected from regular schools located in cities of Gujrat and Jhelum of Pakistan. Respondents’ age ranged from 9-14 years. Resiliency scale named RSCA (Resiliency Scales for children and adolescents) developed by Sandra Prince Embury (2006) was used. RSCA consist of three core theoretical areas: MAS (Sense of Mastery Scale), REL (Sense of Relatedness Scale) and REA (Emotional Reactivity Scale). Results: Findings indicated that there was a significant difference in the resilience level of participants with and without hearing loss. The mean comparison showed that the children with hearing loss showed lower scores on MAS (X̅ = 43.32, SD = 7.55) as well as on REL (X̅ = 49.96, SD = 7.65) as compared to their counterparts on MAS (X̅ = 53.96, SD = 9.90, t= -7.31***) and on REL (X̅ = 68.43, SD = 14.57,t= -10.18***). However children with hearing loss showed higher scores on REA (X̅ = 42.12, SD = 5.84) as compared to hearing participants (X̅ = 28.84, SD = 13.97, t = -8.20***). The findings revealed no significance difference in the resilience level of hearing and deaf children on the basis of their gender and age. Research Outcomes and Future Scope: Children with hearing loss showed a lower level of resilience, therefore, needs a program to develop resilience for better social-emotional adjustment and enhancement of their psychological well-being. In the end, the researcher gave recommendations for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20with%20hearing%20loss" title="children with hearing loss">children with hearing loss</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20Wellbeing" title=" psychological Wellbeing"> psychological Wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=resiliency%20scales%20for%20children%20and%20adolescents" title=" resiliency scales for children and adolescents"> resiliency scales for children and adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/94985/resilience-among-children-with-and-without-hearing-loss-a-comparative-study-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94985.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">183</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> Entrepreneurship in Pakistan: Opportunities and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Jamil">Bushra Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Nudrat%20Baqri"> Nudrat Baqri</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Hassan%20Saeed"> Muhammad Hassan Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Entrepreneurship is creating or setting up a business not only for the purpose of generating profit but also for providing job opportunities. Entrepreneurs are problem solvers and product developers. They use their financial asset for hiring a professional team and combine the innovation, knowledge, and leadership leads to a successful startup or a business. To be a successful entrepreneur, one should be people-oriented and have perseverance. One must have the ability to take risk, believe in his/her potential, and have the courage to move forward in all circumstances. Most importantly, have the ability to take risk and can assess the risk. For STEM students, entrepreneurship is of specific importance and relevance as it helps them not just to be able to solve real life existing complications but to be able to recognize and identify emerging needs and glitches. It is becoming increasingly apparent that in today’s world, there is a need as well as a desire for STEM and entrepreneurship to work together. In Pakistan, entrepreneurship is slowly emerging, yet we are far behind. It is high time that we should introduce modern teaching methods and inculcate entrepreneurial initiative in students. A course on entrepreneurship can be included in the syllabus, and we must invite businessmen and policy makers to motivate young minds for entrepreneurship. This must be pitching competitions, opportunities to win seed funding, and facilities of incubation centers. In Pakistan, there are many good public sector research institutes, yet there is a void gap in the private sector. Only few research institute are meant for research and development. BJ Micro Lab is one of them. It is SECP registered company and is working in academia to promote and facilitate research in STEM. BJ Micro Lab is a women led initiative, and we are trying to promote research as a passion, not as an arduous burden. For this, we are continuously arranging training workshops and sessions. More than 100 students have been trained in ten different workshops arranged at BJ Micro Lab. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM" title=" STEM"> STEM</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=oppurtunties" title=" oppurtunties"> oppurtunties</a> </p> <a href="https://publications.waset.org/abstracts/146285/entrepreneurship-in-pakistan-opportunities-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Comparative Study of Conventional and Satellite Based Agriculture Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafia%20Hassan">Rafia Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Rizwan"> Ali Rizwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Farhan"> Sadaf Farhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Sabir"> Bushra Sabir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to compare the conventional crop monitoring system with the satellite based crop monitoring system in Pakistan. This study is conducted for SUPARCO (Space and Upper Atmosphere Research Commission). The study focused on the wheat crop, as it is the main cash crop of Pakistan and province of Punjab. This study will answer the following: Which system is better in terms of cost, time and man power? The man power calculated for Punjab CRS is: 1,418 personnel and for SUPARCO: 26 personnel. The total cost calculated for SUPARCO is almost 13.35 million and CRS is 47.705 million. The man hours calculated for CRS (Crop Reporting Service) are 1,543,200 hrs (136 days) and man hours for SUPARCO are 8, 320hrs (40 days). It means that SUPARCO workers finish their work 96 days earlier than CRS workers. The results show that the satellite based crop monitoring system is efficient in terms of manpower, cost and time as compared to the conventional system, and also generates early crop forecasts and estimations. The research instruments used included: Interviews, physical visits, group discussions, questionnaires, study of reports and work flows. A total of 93 employees were selected using Yamane’s formula for data collection, which is done with the help questionnaires and interviews. Comparative graphing is used for the analysis of data to formulate the results of the research. The research findings also demonstrate that although conventional methods have a strong impact still in Pakistan (for crop monitoring) but it is the time to bring a change through technology, so that our agriculture will also be developed along modern lines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=area%20frame" title="area frame">area frame</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20reporting%20service" title=" crop reporting service"> crop reporting service</a>, <a href="https://publications.waset.org/abstracts/search?q=CRS" title=" CRS"> CRS</a>, <a href="https://publications.waset.org/abstracts/search?q=sample%20frame" title=" sample frame"> sample frame</a>, <a href="https://publications.waset.org/abstracts/search?q=SRS%2FGIS" title=" SRS/GIS"> SRS/GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite%20remote%20sensing%2F%20geographic%20information%20system" title=" satellite remote sensing/ geographic information system"> satellite remote sensing/ geographic information system</a> </p> <a href="https://publications.waset.org/abstracts/67079/comparative-study-of-conventional-and-satellite-based-agriculture-information-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67079.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">291</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> Eco-Friendly Textiles: The Power of Natural Dyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra">Bushra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the historical significance, ecological benefits, and contemporary applications of natural dyes in textile dyeing, aiming to provide a comprehensive overview of their potential to contribute to a sustainable fashion industry while minimizing ecological footprints. This research explores the potential of natural dyes as a sustainable alternative to synthetic dyes in the textile industry, examining their historical context, sources, and environmental benefits. Natural dyes come from plants, animals, and minerals, including roots, leaves, bark, fruits, flowers, insects, and metal salts, used as mordants to fix dyes to fabrics. Natural dyeing involves extraction, mordanting, and dyeing techniques. Optimizing these processes can enhance the performance of natural dyes, making them viable for contemporary textile applications based on experimental research. Natural dyes offer eco-friendly benefits like biodegradability, non-toxicity, and resource renewables, reducing pollution, promoting biodiversity, and reducing reliance on petrochemicals. Natural dyes offer benefits but face challenges in color consistency, scalability, and performance, requiring industrial production to meet modern consumer standards for durability and colorfastness. Contemporary initiatives in the textile industry include fashion brands like Eileen Fisher and Patagonia incorporating natural dyes, artisans like India Flint's Botanical Alchemy promoting traditional dyeing techniques, and research projects like the European Union's Horizon 2020 program. Natural dyes offer a sustainable textile industry solution, reducing environmental impact and promoting harmony with nature. Research and innovation are paving the way for widespread adoption, transforming textile dyeing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=historical%20significance" title="historical significance">historical significance</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20industry" title=" textile industry"> textile industry</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dyes" title=" natural dyes"> natural dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/186606/eco-friendly-textiles-the-power-of-natural-dyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186606.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">48</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> Biosafety Study of Genetically Modified CEMB Sugarcane on Animals for Glyphosate Tolerance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aminah%20Salim">Aminah Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Idrees%20Ahmed%20Nasir"> Idrees Ahmed Nasir</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Qayyum%20Rao"> Abdul Qayyum Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali"> Muhammad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sohail%20Anjum"> Muhammad Sohail Anjum</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayesha%20Hameed"> Ayesha Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Tabassum"> Bushra Tabassum</a>, <a href="https://publications.waset.org/abstracts/search?q=Anwar%20Khan"> Anwar Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arfan%20Ali">Arfan Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariyam%20Zameer"> Mariyam Zameer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tayyab%20Husnain"> Tayyab Husnain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Risk assessment of transgenic herbicide tolerant sugarcane having CEMB codon optimized cp4EPSPS gene was done in present study. Fifteen days old chicks taken from K&Ns Company were randomly assorted into four groups with eight chicks in each group namely control chicken group fed with commercial diet, non-transgenic group fed with non-experimental sugarcane and transgenic group fed with transgenic sugarcane with minimum and maximum level. Body weights, biochemical analysis for Urea, alkaline phosphatase, alanine transferase, aspartate transferase, creatinine and bilirubin determination and histological examination of chicks fed with four types of feed was taken at fifteen days interval and no significant difference was observed in body weight biochemical and histological studies of all four groups. Protein isolated from the serum sample was analyzed through dipstick and SDS-PAGE, showing the absence of transgene protein in the serum sample of control and experimental groups. Moreover the amplification of cp4EPSPS gene with gene specific primers of DNA isolated from chicks blood and also from commercial diet was done to determine the presence and mobility of any nucleotide fragment of the transgene in/from feed and no amplification was obtained in feed as well as in blood extracted DNA of any group. Also no mRNA expression of cp4EPSPS gene was obtained in any tissue of four groups of chicks. From the results it is clear that there is no deleterious or harmful effect of the CEMB codon optimized transgenic cp4EPSPS sugarcane on the chicks health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicks" title="chicks">chicks</a>, <a href="https://publications.waset.org/abstracts/search?q=cp4EPSPS" title=" cp4EPSPS"> cp4EPSPS</a>, <a href="https://publications.waset.org/abstracts/search?q=glyphosate" title=" glyphosate"> glyphosate</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane" title=" sugarcane"> sugarcane</a> </p> <a href="https://publications.waset.org/abstracts/25869/biosafety-study-of-genetically-modified-cemb-sugarcane-on-animals-for-glyphosate-tolerance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25869.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">372</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> A Novel Heuristic for Analysis of Large Datasets by Selecting Wrapper-Based Features </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Zafar">Bushra Zafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Usman%20Qamar"> Usman Qamar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Large data sample size and dimensions render the effectiveness of conventional data mining methodologies. A data mining technique are important tools for collection of knowledgeable information from variety of databases and provides supervised learning in the form of classification to design models to describe vital data classes while structure of the classifier is based on class attribute. Classification efficiency and accuracy are often influenced to great extent by noisy and undesirable features in real application data sets. The inherent natures of data set greatly masks its quality analysis and leave us with quite few practical approaches to use. To our knowledge first time, we present a new approach for investigation of structure and quality of datasets by providing a targeted analysis of localization of noisy and irrelevant features of data sets. Machine learning is based primarily on feature selection as pre-processing step which offers us to select few features from number of features as a subset by reducing the space according to certain evaluation criterion. The primary objective of this study is to trim down the scope of the given data sample by searching a small set of important features which may results into good classification performance. For this purpose, a heuristic for wrapper-based feature selection using genetic algorithm and for discriminative feature selection an external classifier are used. Selection of feature based on its number of occurrence in the chosen chromosomes. Sample dataset has been used to demonstrate proposed idea effectively. A proposed method has improved average accuracy of different datasets is about 95%. Experimental results illustrate that proposed algorithm increases the accuracy of prediction of different diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title="data mining">data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=generic%20algorithm" title=" generic algorithm"> generic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=KNN%20algorithms" title=" KNN algorithms"> KNN algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=wrapper%20based%20feature%20selection" title=" wrapper based feature selection"> wrapper based feature selection</a> </p> <a href="https://publications.waset.org/abstracts/41534/a-novel-heuristic-for-analysis-of-large-datasets-by-selecting-wrapper-based-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41534.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">316</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> Study of Irritant and Anti-inflammatory Activity of Snuhi/Zaqqum (Euphorbia nerifolia) with Special Reference to Holy Quran and Ayurveda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Khalil%20Ur%20Rahman">Mohammed Khalil Ur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradnya%20Chigle"> Pradnya Chigle</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Farhen"> Bushra Farhen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indian mythology believes that Vedas are eternal treatises. Vedas are categorized into four divisions viz., Rigveda, Yajurveda, Samveda, Atharveda. All these spiritual classics not only deal with rituals and customs but also consist of inclusion of many references related to health. Out of these four, Atharveda deals with maximum principles pertaining to health sciences. Therefore, it is said that the science and the art of Ayurveda has developed from Atharveda. Ayurveda deals with many medicinal plants either as a single therapeutic use or in combination. One such medicinal plant is Snuhi (Euphorbia neriifolia Linn.) which finds its extensive importance along with Haridra and Apamargakshar, in the preparation of Ksharsutra which in turn is used for the treatment of Fistula in Ano. It is interesting to note that this plant Snuhi is also referred in Holy Quran as the Tree of Zaqqum advocated as the food for the sinners as a part of torment. The reference in Surat Ad-Dukhan is as follows: - 44:43-46. “Verily, the tree of Zaqqum will be the food of the sinners, Like boiling oil, it will boil in the bellies, like the boiling of scalding water.” The above verse implies that plant Snuhi/Zaqqum due to irritant property acts as a drastic purgative but at the same time it also possesses anti inflammatory properties in order to relieve the irritation. These properties of Zaqqum has been unfolded in the modern research which states that, Diterpene polycyclic esters are responsible for its toxic and irritant nature whereas; triterpenes are responsible for its anti inflammatory property. Present work will be an effort to review the concept of Quran about latex of the Tree of Zaqqum in terms of its phytochemistry and its therapeutic use in Ksharsutra pertaining to irritant and anti inflammatory property. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ayurveda" title="ayurveda">ayurveda</a>, <a href="https://publications.waset.org/abstracts/search?q=Quran" title=" Quran"> Quran</a>, <a href="https://publications.waset.org/abstracts/search?q=zaqqum" title=" zaqqum"> zaqqum</a>, <a href="https://publications.waset.org/abstracts/search?q=ksharsutra" title=" ksharsutra"> ksharsutra</a>, <a href="https://publications.waset.org/abstracts/search?q=latex%20%20piles" title=" latex piles"> latex piles</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a> </p> <a href="https://publications.waset.org/abstracts/43754/study-of-irritant-and-anti-inflammatory-activity-of-snuhizaqqum-euphorbia-nerifolia-with-special-reference-to-holy-quran-and-ayurveda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43754.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Challenging the Traditional Practice of Continuous Abscess Cavity Packing – A Single Center, Single Blind Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakmali%20Anthony">Lakmali Anthony</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Oathman"> Bushra Oathman</a>, <a href="https://publications.waset.org/abstracts/search?q=Anshini%20Jain"> Anshini Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Raaj%20Chandra"> Raaj Chandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Abscesses are traditionally treated by incision and drainage with the packing of the residual abscess cavity until healing. This method requires regular visits from community nurses for continuous wound packing upon discharge from the hospital and causes considerable patient discomfort. Whether abscess cavity packing offers any advantage over non-packing has not yet been adequately studied to the best of our knowledge. This study aims to determine if there are differences in clinical outcomes of time to healing, fistula formation and recurrence of abscess between abscess cavity packing vs. non-packing groups. Methods: This study was a single-center, single-blind, randomized controlled trial where patients were randomized into packing and non-packing arms. All patients over 18 years presenting to Eastern Health with an abscess requiring incision and drainage in the theatre were invited to participate. Those with underlying conditions that cause recurrent abscesses were excluded. Data were collected from December 2018 to April 2020. Results: There were 63 patients who had abscesses treated with incision and drainage that were enrolled in the study, 52 of which were suitable for analysis. Demographic characteristics were similar in both groups. The packing group had a significantly longer time to heal compared to the non-packing group. Rates of fistula formation and recurrence of abscess were low and there were no statistically significant differences between groups. The packing group had more patients with delayed healing (defined as >60 days) and required more follow-up visits compared to the non-packing group. Conclusion: This pilot study indicates that abscesses can not only be managed safely with incision and drainage alone without the need for continuous abscess cavity packing but also that non-packing may offer clinical benefits to patients with earlier healing of abscesses compared to continuous cavity packing. <p class="card-text"><strong>Keywords:</strong> <a
