direct and indirect effects on people wellbeing. Post-disaster water system serviceability depends on a variety of factors from technical characteristics to social, economic, and organizational attributes of communities. This paper tests the organizational factors affecting water supply resilience to outline how these factors contributed to previous disasters. To do so, a framework is briefly introduced in this study to provide a clear guide to identify the significant relevant organizational factors. Then the factors affecting water serviceability following a disaster are outlines. Next, these factors are measured in the case of Tropical Cyclone Pam, which hit Vanuatu in March 2015. Reviewing the existing literature has also been carried out to obtain a comprehensive understanding of the background A site visit and a series of interviews have also been undertaken following the cyclone to collect site-specific data and information. In the end, the organizational factors were ranked to enable decision makers to identify significance of each factor compared to the others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title="water supply">water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20capacity" title=" organizational capacity"> organizational capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanuatu" title=" Vanuatu"> Vanuatu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tropical%20Cyclone%20Pam" title=" Tropical Cyclone Pam"> Tropical Cyclone Pam</a> </p> <a href="https://publications.waset.org/abstracts/109289/investigating-the-organizational-capacity-of-communities-affecting-water-supply-resilience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109289.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">57</span> Regained Oral Tradition and Identity Construction in House Made of Dawn</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi%20Hu">Yi Hu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> House Made of Dawn is famous novelist N. Scott Momaday’s Pulitzer-winning novel in 1968. The novel tells a story of the struggling life of an Indian named Abel, following the pattern of leaving home, coming home, leaving again, and returning home at the closure of the story. It touches upon the theme of the relationship between Indianness, identity, and tradition. Abel’s confusion over his identity and his constant struggle and exploration of his identity are pivoted on the tradition of oral literature in the form of story-telling. Therefore, this paper aims to analyze the important role of oral tradition in constructing Abel’s Indian cultural identity. The significance of the research lies in two aspects: first of all, the research aims to provide an enlightening perspective for Momaday’s House Made of Dawn in order to gain a better understanding of the novel. Secondly, by emphasizing the importance of traditional culture in identity construction, the research hopes to provide some referential value for people who suffer from identity predicament in modern society. Finally, the paper draws a conclusion that alienation from traditional tribal culture will result in a serious physical and psychological crisis for Indian people. Indian people should adhere to their traditional culture in order to construct their unique cultural identity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=House%20Made%20of%20Dawn" title="House Made of Dawn">House Made of Dawn</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=N.Scott.Momaday" title=" N.Scott.Momaday"> N.Scott.Momaday</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20tradition" title=" oral tradition"> oral tradition</a> </p> <a href="https://publications.waset.org/abstracts/141648/regained-oral-tradition-and-identity-construction-in-house-made-of-dawn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141648.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">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> 'Hindi Madaling Matakot Si Arturo Abel III': How Inescapable Spaces Influence Behavior in the Movie Outside</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tessa%20Savanna%20Cruz">Tessa Savanna Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmela%20Louise%20Angela%20May%20Mijares"> Carmela Louise Angela May Mijares</a>, <a href="https://publications.waset.org/abstracts/search?q=Franchette%20Roshan%20Tabar"> Franchette Roshan Tabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Christy%20Taburada"> Christy Taburada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Through the lens of intergenerational transmission of trauma and toxic masculinity, this study analyzes the Filipino movie Outside, highlighting how inescapable spaces influence the behavior of the main character, Francis Abel. By employing geosemiotics and cognitive film theory, the study explores the representation of space and its impact on the main character's behavior in the movie. As influenced by societal norms that justify violence and the transmission of trauma in Filipino families, the relationship between the main character and his father, Arturo Abel III, is portrayed in the film. Three spaces were identified by the analysis: the house, the room, and the cornfield. Along with the spaces are the signs: door, stairs, mattress, and drawings. These spaces transformed from perceived and conceived spaces into living spaces that imprisoned Francis in his unresolved traumas—these spaces elicit emotional imprisonment, underpinning behaviors that have been influenced by patriarchal ideologies and abuse in the household. The findings reveal that these spaces are no longer just perceived and conceived spaces but can also be active participants in shaping the main character's mental and emotional well-being. The house is a prison, the room has scars, and the cornfield is a reflection of power and pain. The movie will demonstrate how conventional perspectives and expectations about masculinity in the Philippine setting cause childhood trauma by transforming safe spaces into inescapable ones. In order to further understand Filipino cinema and its capacity to construct enduring problems related to masculinity and intergenerational trauma, this study highlights how the film's use of spatial symbolism may challenge societal ideologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geosemiotics" title="geosemiotics">geosemiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=signs" title=" signs"> signs</a>, <a href="https://publications.waset.org/abstracts/search?q=spaces" title=" spaces"> spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior" title=" behavior"> behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=trauma" title=" trauma"> trauma</a> </p> <a href="https://publications.waset.org/abstracts/196462/hindi-madaling-matakot-si-arturo-abel-iii-how-inescapable-spaces-influence-behavior-in-the-movie-outside" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/196462.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">16</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">55</span> Integrating Technology in Teaching and Learning Mathematics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Larry%20Wang">Larry Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to demonstrate how an online homework system is integrated in teaching and learning mathematics and how it improves the student success rates in some gateway mathematics courses. WeBWork provided by the Mathematical Association of America is adopted as the online homework system.

Recent abrupt climate change is increasing the melt rate of these glaciers, introducing the toxins to the watershed. Studies have shown the existence of legacy pollutants in glacial ice, but neither the impact nor quantity of these toxins on downstream populations has been assessed. If these pollutants are released at toxic levels it will be necessary to create a mitigation plan to lower their impact on the affected communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation" title=" adaptation"> adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation" title=" mitigation"> mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/33945/release-of-legacy-persistent-organic-pollutants-and-mitigating-their-effects-in-downstream-communities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33945.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Density Measurement of Underexpanded Jet Using Stripe Patterned Background Oriented Schlieren Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinsuke%20Udagawa">Shinsuke Udagawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Masato%20Yamagishi"> Masato Yamagishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masanori%20Ota"> Masanori Ota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Schlieren method, which has been conventionally used to visualize high-speed flows, has disadvantages such as the complexity of the experimental setup and the inability to quantitatively analyze the amount of refraction of light. The Background Oriented Schlieren (BOS) method proposed by Meier is one of the measurement methods that solves the problems, as mentioned above. The refraction of light is used for BOS method same as the Schlieren method. The BOS method is characterized using a digital camera to capture the images of the background behind the observation area. The images are later analyzed by a computer to quantitatively detect the amount of shift of the background image. The experimental setup for BOS does not require concave mirrors, pinholes, or color filters, which are necessary in the conventional Schlieren method, thus simplifying the experimental setup. However, the defocusing of the observation results is caused in case of using BOS method. Since the focus of camera on the background image leads to defocusing of the observed object. The defocusing of object becomes greater with increasing the distance between the background and the object. On the other hand, the higher sensitivity can be obtained. Therefore, it is necessary to adjust the distance between the background and the object to be appropriate for the experiment, considering the relation between the defocus and the sensitivity. The purpose of this study is to experimentally clarify the effect of defocus on density field reconstruction. In this study, the visualization experiment of underexpanded jet using BOS measurement system with ronchi ruling as the background that we constructed, have been performed. The reservoir pressure of the jet and the distance between camera and axis of jet is fixed, and the distance between background and axis of jet has been changed as the parameter. The images have been later analyzed by using personal computer to quantitatively detect the amount of shift of the background image from the comparison between the background pattern and the captured image of underexpanded jet. The quantitatively measured amount of shift have been reconstructed into a density flow field using the Abel transformation and the Gradstone-Dale equation. From the experimental results, it is found that the reconstructed density image becomes blurring, and noise becomes decreasing with increasing the distance between background and axis of underexpanded jet. Consequently, it is cralified that the sensitivity constant should be greater than 20, and the circle of confusion diameter should be less than 2.7mm at least in this experimental setup. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BOS%20method" title="BOS method">BOS method</a>, <a href="https://publications.waset.org/abstracts/search?q=underexpanded%20jet" title=" underexpanded jet"> underexpanded jet</a>, <a href="https://publications.waset.org/abstracts/search?q=abel%20transformation" title=" abel transformation"> abel transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20field%20visualization" title=" density field visualization"> density field visualization</a> </p> <a href="https://publications.waset.org/abstracts/170604/density-measurement-of-underexpanded-jet-using-stripe-patterned-background-oriented-schlieren-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170604.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">84</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">52</span> Model Development for Real-Time Human Sitting Posture Detection Using a Camera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jheanel%20E.%20Estrada">Jheanel E.

Moreover, if the adequate tools the help these testing are not properly managed, the improvement in the development for various testing could be stooped. This paper presents an optimized process for various testing ASTM D1556 which uses an initial standard process to another one the uses a simpler and improved management tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cone%20sand%20test" title="cone sand test">cone sand test</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20bulk" title=" density bulk"> density bulk</a>, <a href="https://publications.waset.org/abstracts/search?q=ASTM%20D1556" title=" ASTM D1556"> ASTM D1556</a>, <a href="https://publications.waset.org/abstracts/search?q=QA%2FQC" title=" QA/QC "> QA/QC </a> </p> <a href="https://publications.waset.org/abstracts/129392/methodology-for-various-sand-cone-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129392.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">143</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">49</span> Knowledge Sharing in Virtual Community: Societal Culture Considerations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahnaz%20Bashir">Shahnaz Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Usoro"> Abel Usoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Imran%20Khan"> Imran Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hofstede’s culture model is an important model to study culture between different societies.

The present study sought to investigate the roles of counterfactual thinking (CFT) forms (upward CFT vs downward CFT) in the relationship between impulsivity and gambling intention of 371 Nigerian youths who have gambled prior to the study (mean age = 17.37, SD = 4.13). Hayes PROCESS macro result revealed that, after controlling for age, downward CFT was negatively associated with and contributed to a decrease in gambling intention, while upward CFT was positively associated with and contributed to an increase in gambling intention. Mediation analysis result showed that upward CFT amplified the contribution of impulsivity to gambling intention. The association between impulsivity and gambling was partially weakened by downward CFT, even though this weakness was not significant. We conclude that gambling therapies should encourage packages that attenuate upward CFT impulsivity and at the same time, increase downward CFT skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upward%20counterfactuals" title="upward counterfactuals">upward counterfactuals</a>, <a href="https://publications.waset.org/abstracts/search?q=downward%20counterfactuals" title=" downward counterfactuals"> downward counterfactuals</a>, <a href="https://publications.waset.org/abstracts/search?q=gambling%20intention" title=" gambling intention"> gambling intention</a>, <a href="https://publications.waset.org/abstracts/search?q=nigerian%20youths" title=" nigerian youths"> nigerian youths</a> </p> <a href="https://publications.waset.org/abstracts/155365/impulsivity-predicts-gambling-intention-via-upward-than-downward-counterfactual-thinking-among-nigerians-youths" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155365.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">111</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">46</span> Design, Prototyping, Integration, Flight Testing of a 20 cm Span Fully Autonomous Fixed Wing Micro Air Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vivek%20Paul">Vivek Paul</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Nelly"> Abel Nelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoeb%20A%20Adeel"> Shoeb A Adeel</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20Tilak"> R.

Then, after highlighting a few of the ways it promises to heavily impact all aspects of the digital landscape, the focus will shift to Blockchain in the field of education, with specific emphasis placed on practical applications in foreign language education. Blockchain is a decentralized Internet-based software application that guarantees truth in transactions. This means whenever two parties engage in a transaction using Blockchain, it is time-stamped, added to a block of other transactions, and then permanently attached to an unalterable ‘chain’ of blocks. The potential for developing applications with Blockchain is therefore immense, since software systems that ensure the impossibility of outside tampering are invaluable. Innovative ideas in every imaginable domain are presently being entertained and Blockchain in education is no exception. For instance, records kept within and between institutions of students’ grade performance, academic achievement and verification of assignment/course completion are just a few examples of how this new technology might potentially be used to revolutionize education. It is hoped that this paper will be of use to all educators interested in the application of technology in the field of education. <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=disruption" title=" disruption"> disruption</a>, <a href="https://publications.waset.org/abstracts/search?q=potential" title=" potential"> potential</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/107802/exploring-the-potential-of-blockchain-to-improve-higher-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107802.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">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> The Depiction of Suburbia in US-American Independent Movies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sven%20Weidner">Sven Weidner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last two decades, US-American Independent Cinema has been faced with numerous metamorphoses. With regard to style, content, film aesthetics and themes a large array is offered. And as a consequence of the increasing influence of the world wide web and absolutely new ways of production opportunities alter the indie-film scene fundamentally. While in the 90s many independent films were situated in urban spaces -for instance, films of Jim Jarmusch, Abel Ferrara or Quentin Tarantino- there is a tendency from the 2000s years on to go to rural America. Jeff Nichols, Debra Granik or Matthew Porterfield can be named. Suburbia the symbol of the American Dream and in particular of an emerging prosperity after the Second World War is an essential theme with some independent directors; among them indie icons Todd Solondz and Todd Haynes. Based on selected films of both of them the paper explores the formal and aesthetic structures (narrative, drama, montage, lighting, sound, color) of the pictures and how suburbia, its people, and its "perfect" families are shown and unmasked in all facets. Films are: "Happiness" (1998), "Life During Wartime" (2009) and "Far From Heaven" (2002). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=US-independent%20cinema" title="US-independent cinema">US-independent cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Suburbia" title=" Suburbia"> Suburbia</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20history" title=" film history"> film history</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20analysis" title=" film analysis"> film analysis</a> </p> <a href="https://publications.waset.org/abstracts/58663/the-depiction-of-suburbia-in-us-american-independent-movies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58663.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">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> The Power of Symbol in the Powerful Symbol: Case Study of Symbol Visualization Change in the Form of Pelinggih in Bali</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I%20Nyoman%20Larry%20Julianto">I Nyoman Larry Julianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Pribadi%20Widodo"> Pribadi Widodo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The phenomenon of cultural change is the result of the process of shifting, reducing and adding elements of cultural systems because of the process of interaction with the environment. Interestingly in the temple area in Bali, there is a phenomenon of symbol visualization change in the form of pelinggih, which is in the shaped of the car. As a result of the sacralization process of the symbol, the function of its essence is remained as a place of worship. Hindu communities in Bali can accept that phenomenon in their religious life as a process of today's cultural acculturation. Through an interpretive ethnographic study, it is tried to understand the 'creative concept’of that symbol materialization in its interaction process. The result of the research stated that the interaction value of the symbol visualization change is constructed from the application of 'value' and 'meaning' of the previous pelinggih. The ritual procession and the reinforcement of the mythical mind, make the 'value' of the visualization change of the pelinggih leads to a sacred, religious conception. In the future, the development of the human mind is more functional, but it does not eliminate the mythological value due to the interaction with the surrounding social environment, so the visualization of the symbol in the form of pelinggih which is in the shape of the car will be the identity of a new cultural heritage. The understanding of the influence of mental representation of human being in an effort toward his spiritual awareness will be able to be the advanced research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20power%20of%20symbol" title="the power of symbol">the power of symbol</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20change" title=" visual change"> visual change</a>, <a href="https://publications.waset.org/abstracts/search?q=pelinggih" title=" pelinggih"> pelinggih</a>, <a href="https://publications.waset.org/abstracts/search?q=Bali" title=" Bali"> Bali</a> </p> <a href="https://publications.waset.org/abstracts/86256/the-power-of-symbol-in-the-powerful-symbol-case-study-of-symbol-visualization-change-in-the-form-of-pelinggih-in-bali" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86256.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">168</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">42</span> Cooperative Game Theory and Small Hold Farming: Towards A Conceptual Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abel%20Kahuni">Abel Kahuni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cooperative game theory (CGT) postulates that groups of players are crucial units of the decision-making and impose cooperative behaviour. Accordingly, cooperative games are regarded as competition between coalitions of players, rather than between individual players. However, the basic supposition in CGT is that the cooperative is formed by all players. One of the emerging questions in CGT is how to develop cooperatives and fairly allocate the payoff. Cooperative Game Theory (CGT) may provide a framework and insights into the ways small holder farmers in rural resettlements may develop competitive advantage through marketing cooperatives. This conceptual paper proposes a non-competition model for small holder farmers of homogenous agri-commodity under CGT conditions. This paper will also provide brief insights into to the theory of cooperative games in-order to generate an understanding of CGT, cooperative marketing gains and its application in small holder farming arrangements. Accordingly, the objective is to provide a basic introduction to this theory in connection with economic competitive theories in the context of small holder farmers. The key value proposition of CGT is the equitable and fair sharing of cooperative gains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title="game theory">game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperative%20game%20theory" title=" cooperative game theory"> cooperative game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperatives" title=" cooperatives"> cooperatives</a>, <a href="https://publications.waset.org/abstracts/search?q=competition" title=" competition"> competition</a> </p> <a href="https://publications.waset.org/abstracts/168075/cooperative-game-theory-and-small-hold-farming-towards-a-conceptual-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168075.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">84</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">41</span> Investigating the Performance of Power Industry in a Developing Nation for Industrialization and Environmental Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abel%20Edeowede%20Abhulimen">Abel Edeowede Abhulimen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to supply irregularity and frequent outages, the need for reliability in power supply has grown unsatisfactorily over time in developing nations, impeding industrialization and fueling insecurity. This article attempts to break down the Nigerian power issue into its numerous sub-sectors in order to pinpoint the industry's ailment and suggest a viable fix. Monthly average performance data were obtained for the various sub-sectors across the industry for eight consecutive quarters. Whereas the amount of energy generated was found to be insufficient to engender industrialization in a nation like Nigeria, the transmission infrastructure was inadequate for the amount of power needed to be wheeled. Additionally, the distribution sub-sector was plagued with problems such as revenue collection inefficiency, severe enough to impede the growth of the entire industry. The country's goal of attaining energy sufficiency and industrialization would significantly be closer to reality with a conscious effort to increase the base of power generation through aggressive investment in Combined Cycle Gas Turbines (CCGT), decentralization of the transmission infrastructure, and strict monitoring of the distribution sub-sector for improved accountability and system reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20industry" title=" power industry"> power industry</a>, <a href="https://publications.waset.org/abstracts/search?q=industrialization" title=" industrialization"> industrialization</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/179971/investigating-the-performance-of-power-industry-in-a-developing-nation-for-industrialization-and-environmental-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179971.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">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> A Greener Approach for the Recovery of Proteins from Meat Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Hernandez">Jesus Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Zead%20Elzoeiry"> Zead Elzoeiry</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.%20S.%20Islam"> Md.

Spent peppermint tea (PM), powdered purple corn cob (PC), natural clay (NC) and chemically-modified clay (MC) were investigated to elucidate the effects of pH, adsorbent dose, initial protein concentration, presence of salts and heavy metals. Equilibrium data were fitted according to isotherm models, reporting a maximum adsorption capacity at pH 8 of 318 and 344 mg BSA/g of PM and NC, respectively. Moreover, Hb displayed maximum adsorption capacity at pH 5 of 125 and 143 mg/g of PM and PC, respectively. Hofmeister salt effect was only observed for PM/Hb system. Salts tend to decrease protein adsorption, and the presence of Cu(II) ions had negligible impacts on the adsorption onto NC and PC. Desorption experiments confirmed that more than 85% of both proteins can be recovered with diluted acids and bases. SEM, EDX, and TGA analyses demonstrated that the adsorbents have favorable morphological and mechanical properties. The long-term goal of this study aims to recover soluble proteins from industrial wastewaters to produce animal food or any protein-based product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=albumin" title=" albumin"> albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=hemoglobin" title=" hemoglobin"> hemoglobin</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20peppermint%20leaf" title=" spent peppermint leaf"> spent peppermint leaf</a> </p> <a href="https://publications.waset.org/abstracts/113481/a-greener-approach-for-the-recovery-of-proteins-from-meat-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113481.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">109</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">39</span> Explaining the Changes in Contentious Politics of China: A Comparative Study of Falun Gong and 'Diaosi'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Larry%20Lai">Larry Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Evans%20Leung"> Evans Leung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Falun gong is a self-proclaimed religious group that has been under crackdown by Beijing for more than two decades.

This paper seeks to explain the different strategies adopted by the People's Republic of China (PRC) regime in handling these two potential threatening communities. Both communities share some obvious similarities: (1) both have massive nation-wide participation; (2) both have attempted to challenge the PRC's authority through contentious means; (3) both have high level of mobility, online or offline; and (4) both have at first been unnoticed until the threat against the PRC have taken form. But the strategies the PRC endorsed against the communities were, in many ways, different. The question is: if the strategy against Falun Gong has been an effective one, why used other strategies against Diaosi? The authors argue that the main reason for using different strategies lies in the differences between the two communities in terms of (i) the nature of the groups, and (ii) the group dynamics. Lastly, based on this analysis, the authors attempt to explore the possible strategies that the PRC would adopt against the Hong Kong cyber-world political community in light of the latest national security law in Hong Kong. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contentious%20politics" title="contentious politics">contentious politics</a>, <a href="https://publications.waset.org/abstracts/search?q=Diaosi" title=" Diaosi"> Diaosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Falun%20Gong" title=" Falun Gong"> Falun Gong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Kong" title=" Hong Kong"> Hong Kong</a>, <a href="https://publications.waset.org/abstracts/search?q=People%27s%20Republic%20of%20China" title=" People's Republic of China"> People's Republic of China</a> </p> <a href="https://publications.waset.org/abstracts/127836/explaining-the-changes-in-contentious-politics-of-china-a-comparative-study-of-falun-gong-and-diaosi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127836.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">150</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">38</span> Controlling Dimensions and Shape of Carbon Nanotubes Using Nanoporous Anodic Alumina under Different Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amine%20Mezni">Amine Mezni</a>, <a href="https://publications.waset.org/abstracts/search?q=Merfat%20Algethami"> Merfat Algethami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Aldalbahi"> Ali Aldalbahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arwa%20Alrooqi"> Arwa Alrooqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Santos"> Abel Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Dusan%20Losic"> Dusan Losic</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Alharthi"> Sarah Alharthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Altalhi"> Tariq Altalhi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In situ synthesis of carbon nanotubes featuring different diameters (10-200 nm), lengths (1 to 100 µm) and periodically nanostructured shape was performed in a custom designed chemical vapor deposition (CVD) system using nanoporous anodic alumina (NAA) under different conditions. The morphology of the resulting CNTs/NAA composites and free-standing CNTs were analyzed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The results confirm that highly ordered arrays of CNTs with precise control of nanotube dimensions in the range 20-200 nm with tube length in the range < 1 µm to > 100 μm and with periodically shaped morphology can be fabricated using nanostructured NAA templates prepared by anodization. This technique allows us to obtain tubes open at one / both ends with a uniform diameter along the pore length without using any metal catalyst. Our finding suggests that this fabrication strategy for designing new CNTs membranes and structures can be significant for emerging applications as molecular separation/transport, optical biosensing, and drug delivery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=CVD%20approach" title=" CVD approach"> CVD approach</a>, <a href="https://publications.waset.org/abstracts/search?q=composites%20membrane" title=" composites membrane"> composites membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoporous%20anodic%20alumina" title=" nanoporous anodic alumina"> nanoporous anodic alumina</a> </p> <a href="https://publications.waset.org/abstracts/65463/controlling-dimensions-and-shape-of-carbon-nanotubes-using-nanoporous-anodic-alumina-under-different-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65463.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">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Assessing Vertical Distribution of Soil Organic Carbon Stocks in Westleigh Soil under Shrub Encroached Rangeland, Limpopo Province, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abel%20L.%20Masotla">Abel L.

Despite this, in-depth soil carbon dynamics remain poorly understood, especially in arid and semi-arid rangelands. The objective of this study was to quantify and compare the vertical distribution of soil organic carbon stocks (SOCs) in shrub-encroached and open grassland sites. To achieve this, soil samples were collected vertically at 10 cm depth intervals under both sites. The results showed that SOC was on average 19% and 13% greater in the topsoil and subsoil respectively, under shrub-encroached grassland compared to open grassland. In both topsoil and subsoil, lower SOCs were found under shrub-encroached (4.53 kg m⁻² and 3.90 kgm⁻²) relative to open grassland (4.39 kgm⁻² and 3.67 kgm⁻²). These results demonstrate that deeper soil horizon play a critical role in the storage of SOC in savanna grassland. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=savanna%20grasslands" title="savanna grasslands">savanna grasslands</a>, <a href="https://publications.waset.org/abstracts/search?q=shrub-encroachment" title=" shrub-encroachment"> shrub-encroachment</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20organic%20carbon" title=" soil organic carbon"> soil organic carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20distribution" title=" vertical distribution"> vertical distribution</a> </p> <a href="https://publications.waset.org/abstracts/111178/assessing-vertical-distribution-of-soil-organic-carbon-stocks-in-westleigh-soil-under-shrub-encroached-rangeland-limpopo-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111178.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Correlation and Prediction of Biodiesel Density </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nieves%20M.%20C.%20Talavera-Prieto">Nieves M.

In this study, cottonseed oil was transesterified into biodiesel and its density was measured at temperatures between 288 K and 358 K and pressures between 0.1 MPa and 30 MPa, with expanded uncertainty estimated as ±1.6 kg.m^-3. Experimental pressure-volume-temperature (pVT) cottonseed data was used along with literature data relative to other 18 biodiesels, in order to build a database used to test the correlation of density with temperarure and pressure using the Goharshadi–Morsali–Abbaspour equation of state (GMA EoS). To our knowledge, this is the first that density measurements are presented for cottonseed biodiesel under such high pressures, and the GMA EoS used to model biodiesel density. The new tested EoS allowed correlations within 0.2 kg•m-3 corresponding to average relative deviations within 0.02%. The built database was used to develop and test a new full predictive model derived from the observed linear relation between density and degree of unsaturation (DU), which depended from biodiesel FAMEs profile. The average density deviation of this method was only about 3 kg.m-3 within the temperature and pressure limits of application. These results represent appreciable improvements in the context of density prediction at high pressure when compared with other equations of state. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel%20density" title="biodiesel density">biodiesel density</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation" title=" correlation"> correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=equation%20of%20state" title=" equation of state"> equation of state</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/17127/correlation-and-prediction-of-biodiesel-density" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17127.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">621</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Improving Activity Recognition Classification of Repetitious Beginner Swimming Using a 2-Step Peak/Valley Segmentation Method with Smoothing and Resampling for Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Larry%20Powell">Larry Powell</a>, <a href="https://publications.waset.org/abstracts/search?q=Seth%20Polsley"> Seth Polsley</a>, <a href="https://publications.waset.org/abstracts/search?q=Drew%20Casey"> Drew Casey</a>, <a href="https://publications.waset.org/abstracts/search?q=Tracy%20Hammond"> Tracy Hammond</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human activity recognition (HAR) systems have shown positive performance when recognizing repetitive activities like walking, running, and sleeping. Water-based activities are a reasonably new area for activity recognition. However, water-based activity recognition has largely focused on supporting the elite and competitive swimming population, which already has amazing coordination and proper form. Beginner swimmers are not perfect, and activity recognition needs to support the individual motions to help beginners. Activity recognition algorithms are traditionally built around short segments of timed sensor data. Using a time window input can cause performance issues in the machine learning model. The window’s size can be too small or large, requiring careful tuning and precise data segmentation. In this work, we present a method that uses a time window as the initial segmentation, then separates the data based on the change in the sensor value. Our system uses a multi-phase segmentation method that pulls all peaks and valleys for each axis of an accelerometer placed on the swimmer’s lower back. This results in high recognition performance using leave-one-subject-out validation on our study with 20 beginner swimmers, with our model optimized from our final dataset resulting in an F-Score of 0.95. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time%20window" title="time window">time window</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%2Fvalley%20segmentation" title=" peak/valley segmentation"> peak/valley segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20extraction" title=" feature extraction"> feature extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=beginner%20swimming" title=" beginner swimming"> beginner swimming</a>, <a href="https://publications.waset.org/abstracts/search?q=activity%20recognition" title=" activity recognition"> activity recognition</a> </p> <a href="https://publications.waset.org/abstracts/156773/improving-activity-recognition-classification-of-repetitious-beginner-swimming-using-a-2-step-peakvalley-segmentation-method-with-smoothing-and-resampling-for-machine-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156773.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">127</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> Efficacy of Different Pest Control Strategies against Citrus Rind Borer (Prays Eendolemma Diakonoff) Infesting Pummelo (Citrus maxima)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Larry%20V.%20Aceres">Larry V.

The experiment was laid-out in Completely Randomized Design (CRD) with five treatments replicated three times. The treatments were: T1- curry tree leaf leachate, T2- neem tree leaf leachate, T3- bagging with an ordinary net, T4- treated check (chlorpyrifos & betacyflutrin) and T5- untreated check. Data were analyzed using the Analysis of Variance and the differences among treatment means were computed using the Tukey’s Honest Significant Difference. The results of the study revealed that the curry tree leaf leachate and bagging treatments provide significant protection to the pummelo fruits which is comparable with the treated check (chlorpyrifos & betacyflutrin). Neem tree leaf leachate is not effective in controlling citrus rind borer which is comparable with the untreated check.

Yet still today many leaders of creativity are not sure how to introduce it to their teachers. It is impossible to simultaneously introduce every aspect of creativity into a work climate and reach any degree of organizational coherence. The number of alternatives to explore is so great; the information teachers need to learn is so vast, that even an approximation to including every concept and theory of creativity into the school organization is hard to conceive. Effective leaders of creativity need evidence-based and practical guidance for introducing and stimulating creativity in others. Machine learning models reveal new findings from KEYS Survey© data about teacher perceptions of stimulants and barriers to their individual and collective creativity. Findings from predictive and causal models provide leaders with a rational for decision-making when introducing creativity into their organization. Leaders should focus on management practices first. Analyses reveal that creative outcomes are more likely to occur when teachers perceive supportive management practices: providing teachers with challenging work that calls for their best efforts; allowing freedom and autonomy in their practice of work; allowing teachers to form creative work-groups; and, recognizing them for their efforts. Once management practices are in place, leaders should focus their efforts on modeling risk-taking, providing optimal amounts of preparation time, and evaluating teachers fairly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=KEYS%20survey" title=" KEYS survey"> KEYS survey</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching" title=" teaching"> teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20climate" title=" work climate"> work climate</a> </p> <a href="https://publications.waset.org/abstracts/101653/machine-learning-for-rational-decision-making-introducing-creativity-to-teachers-within-a-school-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101653.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">171</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> Histochemical Localization of Hepatitis B Surface Antigen in Hepatocellular Carcinoma: An Evaluation of Two Staining Techniques in a Tertiary Hospital in Calabar, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imeobong%20Joseph%20Inyang">Imeobong Joseph Inyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Aniekan-Augusta%20Okon%20Eyo"> Aniekan-Augusta Okon Eyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20William%20Essien"> Abel William Essien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hepatitis B virus (HBV) is one of the known human carcinogens. The presence of HBsAg in liver tissues indicates active viral replication. More than 85% of Hepatocellular Carcinoma (HCC) cases occur in countries with increased rates of chronic HBV infection. An evaluation study to determine the relationship between positivity for HBsAg and development of HCC and its distribution between age and gender of subjects was done. Shikata Orcein and Haematoxylin and Eosin (H&E) staining techniques were performed on liver sections. A total of 50 liver tissue specimens comprising 38 biopsy and 12 post-mortem specimens were processed. Thirty-five of the 50 specimens were positive for HBsAg with Orcein stain whereas only 16 were positive with H&E stain, and these were also positive with Orcein stain, giving an HBsAg prevalence of 70.0% (35/50). The prevalence of HCC in the study was 56.0% (28/50), of which 21 (75.0%) cases were positive for HBsAg, 18 (64.3%) were males while 10 (35.7%) were females distributed within the age range of 20-70 years. The highest number of HBsAg positive HCC cases, 7/21 (33.3%) occurred in the age group 40-49 years. There was no relationship in the pattern of distribution of HCC between age and gender using the Pearson correlation coefficient (r = 0.0474; P < 0.05). HBV infection predisposed to HCC. Orcein technique was more specific and is therefore recommended for screening of liver tissues where facilities for immunohistochemistry are inaccessible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20B.%20surface%20antigen" title="Hepatitis B. surface antigen">Hepatitis B. surface antigen</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatocellular%20carcinoma" title=" hepatocellular carcinoma"> hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=orcein" title=" orcein"> orcein</a>, <a href="https://publications.waset.org/abstracts/search?q=pathology" title=" pathology"> pathology</a> </p> <a href="https://publications.waset.org/abstracts/6196/histochemical-localization-of-hepatitis-b-surface-antigen-in-hepatocellular-carcinoma-an-evaluation-of-two-staining-techniques-in-a-tertiary-hospital-in-calabar-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6196.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">322</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> Thermo-Oxidative Degradation of Asphalt Modified with High Density Polyethylene and Engine Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helder%20Shelton%20Abel%20Manguene">Helder Shelton Abel Manguene</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Buonocore"> Giovanna Buonocore</a>, <a href="https://publications.waset.org/abstracts/search?q=Herminio%20Francisco%20Muiambo"> Herminio Francisco Muiambo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paved roads are designed for 10-15 years of life. However, many asphalted roads suffer degradation before reaching their lifetime due to aging caused by load conditions and climatic factors. Oxidation is the main asphalt aging mechanism, which leads to a reduced bond between aggregate particles, increasing the potential for stripping and moisture damage, decreasing fatigue lifetime and reducing resistance to thermal cracking. To improve the performance of asphalt and mitigate these problems, modifiers such as polymers, oils and certain residues have been used. This work aims to study the influence of the addition of high-density polyethylene (HDPE) and engine oil on the thermal stability of asphalt in an oxidizing atmosphere. For the study, compositions containing asphalt, motor oil and HDPE were prepared, varying the concentration of the motor oil by 2.5%, 5%, 7.5% and 10% and keeping the HDPE concentration fixed at 5%. The results show that the pure asphalt sample is degraded in a single step that starts at approximately 311 ºC; All samples of modified asphalt except the one that contains 5% of motor oil have three degradation steps that start below the starting temperature of degradation of pure asphalt (about 250-300 ºC); The temperature of onset of degradation of the modified asphalt is shown to decrease as the concentration of the motor oil increases, suggesting a slight loss of thermal stability of the asphalt as the quantity of the motor oil increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asphalt" title="Asphalt">Asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=DTG" title=" DTG"> DTG</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20oil" title=" engine oil"> engine oil</a>, <a href="https://publications.waset.org/abstracts/search?q=HDPE" title=" HDPE"> HDPE</a>, <a href="https://publications.waset.org/abstracts/search?q=TGA" title=" TGA"> TGA</a> </p> <a href="https://publications.waset.org/abstracts/138431/thermo-oxidative-degradation-of-asphalt-modified-with-high-density-polyethylene-and-engine-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138431.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">215</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> Characteristics of Serum Exosomes after Burn Injury and Dermal Fibroblast Regulation by Exosomes in Vitro</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jie%20Ding">Jie Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingying%20Pan"> Yingying Pan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shammy%20Raj"> Shammy Raj</a>, <a href="https://publications.waset.org/abstracts/search?q=Lindy%20Schaffrick"> Lindy Schaffrick</a>, <a href="https://publications.waset.org/abstracts/search?q=Jolene%20Wong"> Jolene Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoinette%20Nguyen"> Antoinette Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharada%20Manchikanti"> Sharada Manchikanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Larry%20Unsworth"> Larry Unsworth</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Kwan"> Peter Kwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20E.%20Tredget"> Edward E.

More research is needed to fully understand the EXO characteristics and mechanisms of EXO-mediated wound healing, especially wound healing after burn injury. Methods: Total EXOs were isolated from 85 serum samples of 29 burn patients and 13 healthy individuals. We characterized the EXOs for morphology and density, serum concentration, protein level, marker expression, size distribution, and cytokine content. After confirmation of EXO uptake by dermal fibroblasts, we also explored functional regulation of primary human normal skin and hypertrophic scar fibroblast cell lines by the EXOs in vitro, including cell proliferation and apoptosis. Results: EXOs dynamically changed their morphology, density, size, and cytokine level during wound healing in burn patients, which were correlated with burn severity and the stages of wound healing. EXOs from both burn patients and healthy individuals stimulated dermal fibroblast proliferation and apoptosis. Conclusion: EXO features may be important signals that influence wound healing after burn injury; however, to understand the mechanisms by which EXOs regulated the fibroblasts in healing wounds, further studies will be required in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exosome" title="exosome">exosome</a>, <a href="https://publications.waset.org/abstracts/search?q=burn" title=" burn"> burn</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing" title=" wound healing"> wound healing</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophic%20scarring" title=" hypertrophic scarring"> hypertrophic scarring</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a> </p> <a href="https://publications.waset.org/abstracts/170905/characteristics-of-serum-exosomes-after-burn-injury-and-dermal-fibroblast-regulation-by-exosomes-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170905.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">88</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> Assessment of Aflatoxins in Marketed Fish: A Potential Forgotten Risk in Cameroon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evelyne%20Nguegwouo">Evelyne Nguegwouo</a>, <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Fonkem%20Sonfack%20Tsakem"> Raoul Fonkem Sonfack Tsakem</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Wade"> Abel Wade</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Nama%20Medoua"> Gabriel Nama Medoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamgaing%20Theophile"> Kamgaing Theophile</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fresh and smoked fish are widely consumed in Cameroon. The traditional nature of smoking, the lack of hygiene in production, the poor preservation of stocks and the long storage time for certain types of fish considerably favor the contamination of products by molds, which secrete toxic molecules called mycotoxins. Today there are more than 400 types of mycotoxins, Aflatoxins being the most formidable. These toxins are considered carcinogenic in humans. It is in this perspective that we proposed to evaluate the total Aflatoxins in the fish marketed and consumed by the populations of the city of Yaoundé in Cameroon. On the one hand, it was a question of conducting a survey of fish consumers and sellers in points of sale, sampling fish of three species [Marquereau (Scomber scombrus), Cod (Gadus morhua) and Bifaka (Ethmalosa fimbriata)], randomly in some markets of the city to evaluate the total Aflatoxins contents (B1, B2, G1, G2) by the quantitative ELISA method and finally to estimate the level of exposure of the populations. It emerges from this study that of the 30 samples analyzed, 96.1% contained total Aflatoxins and two samples had total Aflatoxins levels above the standard, which is 20 ppb. These first results show that the risk is present in Cameroon and in order to improve the quality of marketed fish in terms of mycotoxins, a more thorough control must be done from the production chain to the consumer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aflatoxins" title="aflatoxins">aflatoxins</a>, <a
