chemistry to students is one of the determining factors towards their achievement. Thus, the study investigated the relationship between classroom interaction patterns and students’ achievement in Chemistry. The purpose of this study was to identify patterns of interaction in an observed chemistry classroom, determine the amount of teacher talk, student talk and period of silence and to find out the relationship between them and the mean achievement scores of students. Five research questions and three hypotheses guided the study. The study was a correlational survey. The sample consisted of 450 (212males and 238 females) senior secondary one students and 12 (5males and 7 females) chemistry teachers drawn from 12 selected secondary schools in Awka Education Zone of Anambra state. In each of the 12 selected schools, an intact class was used. Science Interaction Category (SIC) and Chemistry Achievement Test (CAT) were developed, validated and used for data collection. Each teacher was observed three times and the interaction patterns coded using a coding sheet containing the Science Interaction Category. At the end of the observational period, the Chemistry Achievement Test (for collection of data on students’ achievement in chemistry) was administered on the students. Frequencies, percentage, mean, standard deviation and Pearson product moment correlation were used for data analysis. The result showed that the percentages of teacher talk, student talk and silence were 59.6%, 37.6% and 2.8% respectively. The Pearson correlation coefficient(r) for teacher talk, student talk and silence were -0.61, 0.76 and-0.18 respectively. The result showed negative and significant relationship between teacher talk and mean achievement scores of students; positive and significant relationship between student talk and mean achievement scores of students but there is no relationship between period of silence and mean achievement scores of students at 0.05 significant levels. The following recommendations were made based on the findings: teachers should establish high level of student talk through initiation and response as it promotes involvement and enhances achievement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title="academic achievement">academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=classroom" title=" classroom"> classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=interactions%20patterns" title=" interactions patterns"> interactions patterns</a> </p> <a href="https://publications.waset.org/abstracts/68619/classroom-interaction-patterns-as-correlates-of-senior-secondary-school-achievement-in-chemistry-in-awka-education-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68619.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">309</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">261</span> An Analysis of Emmanuel Macron&#039;s Campaign Discourse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robin%20Turner">Robin Turner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of the strengthening conservative movements such as “Brexit” and the election of US President Donald Trump, the global political stage was shaken up by the election of Emmanuel Macron to the French presidency, defeating the far-right candidate Marine Le Pen. The election itself was a first for the Fifth Republic in which neither final candidate was from the traditional two major political parties: the left Parti Socialiste (PS) and the right Les Républicains (LR). Macron, who served as the Minister of Finance under his predecessor, founded the centrist liberal political party En Marche! in April 2016 before resigning from his post in August to launch his bid for the presidency. Between the time of the party’s creation to the first round of elections a year later, Emmanuel Macron and En Marche! had garnered enough support to make it to the run-off election, finishing far ahead of many seasoned national political figures. Now months into his presidency, the youngest President of the Republic shows no sign of losing fuel anytime soon. His unprecedented success raises a lot of questions with respect to international relations, economics, and the evolving relationship between the French government and its citizens. The effectiveness of Macron’s campaign, of course, relies on many factors, one of which is his manner of communicating his platform to French voters. Using data from oral discourse and primary material from Macron and En Marche! in sources such as party publications and Twitter, the study categorizes linguistic instruments – address, lexicon, tone, register, and syntax – to identify prevailing patterns of speech and communication. The linguistic analysis in this project is two-fold. In addition to these findings’ stand-alone value, these discourse patterns are contextualized by comparable discourse of other 2017 presidential candidates with high emphasis on that of Marine Le Pen. Secondly, to provide an alternative approach, the study contextualizes Macron’s discourse using those of two immediate predecessors representing the traditional stronghold political parties, François Hollande (PS) and Nicolas Sarkozy (LR). These comparative methods produce an analysis that gives insight to not only a contributing factor to Macron’s successful 2017 campaign but also provides insight into how Macron’s platform presents itself differently to previous presidential platforms. Furthermore, this study extends analysis to supply data that contributes to a wider analysis of the defeat of “traditional” French political parties by the “start-up” movement En Marche!. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Macron" title="Emmanuel Macron">Emmanuel Macron</a>, <a href="https://publications.waset.org/abstracts/search?q=French" title=" French"> French</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20analysis" title=" discourse analysis"> discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20discourse" title=" political discourse"> political discourse</a> </p> <a href="https://publications.waset.org/abstracts/77596/an-analysis-of-emmanuel-macrons-campaign-discourse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77596.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">261</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">260</span> Microsatellite-Based Genetic Variations and Relationships among Some Farmed Nile Tilapia Populations in Ghana: Implications for Nile Tilapia Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acheampong%20Addo">Acheampong Addo</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Odartei%20Armah"> Emmanuel Odartei Armah</a>, <a href="https://publications.waset.org/abstracts/search?q=Seth%20Koranteng%20Agyakwah"> Seth Koranteng Agyakwah</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruby%20Asmah"> Ruby Asmah</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Tetteh-Doku%20Mensah"> Emmanuel Tetteh-Doku Mensah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhoda%20Lims%20Diyie"> Rhoda Lims Diyie</a>, <a href="https://publications.waset.org/abstracts/search?q=Sena%20Amewu"> Sena Amewu</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Ragasa"> Catherine Ragasa</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Kofi%20Abban"> Edward Kofi Abban</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Yaw%20Osei-Atweneboana"> Mike Yaw Osei-Atweneboana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigated genetic variation and relationships among populations of Nile tilapia cultured in small-scale fish farms in selected regions of Ghana.

Fish from the 16 populations (made up of 14 farms and 2 selectively bred populations) clustered into three groups: 7 populations clustered with the GIFT-derived strain, 4 populations clustered with the Akosombo strain, and three populations were in a separate cluster. The clustering pattern indicated groups of different strains of Nile tilapia cultured. Mantel correlation test also showed low genetic variations among the 16 populations hence the need to boost seed quality in order to accelerate aquaculture production in Ghana. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microsatellites" title="microsatellites">microsatellites</a>, <a href="https://publications.waset.org/abstracts/search?q=small-%20scale" title=" small- scale"> small- scale</a>, <a href="https://publications.waset.org/abstracts/search?q=Nile%20tilapia" title=" Nile tilapia"> Nile tilapia</a>, <a href="https://publications.waset.org/abstracts/search?q=akosombo%20strain" title=" akosombo strain"> akosombo strain</a>, <a href="https://publications.waset.org/abstracts/search?q=GIFT%20strain" title=" GIFT strain"> GIFT strain</a> </p> <a href="https://publications.waset.org/abstracts/163597/microsatellite-based-genetic-variations-and-relationships-among-some-farmed-nile-tilapia-populations-in-ghana-implications-for-nile-tilapia-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163597.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">167</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">259</span> The Imminent Other in Anna Deavere Smith’s Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joy%20Shihyi%20Huang">Joy Shihyi Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the concept of community in Anna Deavere Smith’s performance, one that challenges and explores existing notions of justice and the other. In contrast to unwavering assumptions of essentialism that have helped to propel a discourse on moral agency within the black community, Smith employs postmodern ideas in which the theatrical attributes of doubling and repetition are conceptualized as part of what Marvin Carlson coined as a ‘memory machine.’ Her dismissal of the need for linear time, such as that regulated by Aristotle’s The Poetics and its concomitant ethics, values, and emotions as a primary ontological and epistemological construct produced by the existing African American historiography, demonstrates an urgency to produce an alternative communal self to override metanarratives in which the African Americans’ lives are contained and sublated by specific historical confines. Drawing on Emmanuel Levinas’ theories in ethics, specifically his notion of ‘proximity’ and ‘the third,’ the paper argues that Smith enacts a new model of ethics by launching an acting method that eliminates the boundary of self and other. Defying psychological realism, Smith conceptualizes an approach to acting that surpasses the mere mimetic value of invoking a ‘likeness’ of an actor to a character, which as such, resembles the mere attribution of various racial or sexual attributes in identity politics. Such acting, she contends, reduces the other to a representation of, at best, an ultimate rendering of me/my experience. She instead appreciates ‘unlikeness,’ recognizes the unavoidable actor/character gap as a power that humbles the self, whose irreversible journey to the other carves out its own image. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Deavere%20Smith" title="Anna Deavere Smith">Anna Deavere Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Levinas" title=" Emmanuel Levinas"> Emmanuel Levinas</a>, <a href="https://publications.waset.org/abstracts/search?q=other" title=" other"> other</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/113730/the-imminent-other-in-anna-deavere-smiths-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113730.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">155</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">258</span> Assessment of the Impact of Teaching Methodology on Skill Acquisition in Music Education among Students in Emmanuel Alayande University of Education, Oyo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omotayo%20Abidemi%20Funmilayo">Omotayo Abidemi Funmilayo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skill acquisition in professional fields has been prioritized and considered important to demonstrate the mastery of subject matter and present oneself as an expert in such profession. The ability to acquire skills in different fields, however calls for different method from the instructor or teacher during training. Music is not an exception of such profession, where there exist different area of skills acquisition require practical performance. This paper, however, focused on the impact and effects of different methods on acquisition of practical knowledge in the handling of some musical instruments among the students of Emmanuel Alayande College of Education, Oyo. In this study, 30 students were selected and divided into two groups based on the selected area of learning, further division were made on each of the two major groups to consist of five students each, to be trained using different methodology for two months and three hours per week. Comparison of skill acquired were made using standard research instrument at reliable level of significance, test were carried out on the thirty students considered for the study based on area of skill acquisition. The students that were trained on the keyboard and saxophone using play way method, followed by the students that were trained using demonstration method while the set of students that received teaching instruction through lecture method performed below average. In conclusion, the study reveals that ability to acquire professional skill on handling musical instruments are better enhanced using play way method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20education" title="music education">music education</a>, <a href="https://publications.waset.org/abstracts/search?q=skill%20acquisition" title=" skill acquisition"> skill acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=keyboard" title=" keyboard"> keyboard</a>, <a href="https://publications.waset.org/abstracts/search?q=saxophone" title=" saxophone"> saxophone</a> </p> <a href="https://publications.waset.org/abstracts/171916/assessment-of-the-impact-of-teaching-methodology-on-skill-acquisition-in-music-education-among-students-in-emmanuel-alayande-university-of-education-oyo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171916.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">72</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">257</span> Egg Yolk and Serum Cholesterol Reducing Effect of Garlic and Natural Cocoa Powder Using Laying Birds as Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onyimonyi%20Anselm%20Ego">Onyimonyi Anselm Ego</a>, <a href="https://publications.waset.org/abstracts/search?q=Obi-Keguna%20Christy"> Obi-Keguna Christy</a>, <a href="https://publications.waset.org/abstracts/search?q=Dim%20Emmanuel%20Chinonso"> Dim Emmanuel Chinonso</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugwuanyi%20Evelyn"> Ugwuanyi Evelyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzochukwu%20Ifeanyi%20Emmanuel"> Uzochukwu Ifeanyi Emmanuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A total of 144 Shaver Brown Layers in their sixteenth week of lay were used in a twelve weeks study to evaluate the egg yolk and serum cholesterol of the birds when fed varying dietary combinations of garlic and natural cocoa powder. The birds were randomly assigned into nine dietary treatments with 16 birds per treatment. Each bird was housed separately in a cage measuring 45 cm x 35 cm in an open sided battery cage house typical of the tropics. A standard poultry mash diet with 16.5% CP and 2800 KcalME/kg was formulated as the basal ration which also served as the control diet. Garlic and natural cocoa powder were incorporated in varying combinations (50 g or 100 g/100 kg of feed) in the remaining eight treatments. Weekly data of egg weight, egg length, egg diameter, yolk weight, albumen weight and hen day egg production were kept. Egg yolk and serum cholesterol levels were determined using a Randox kit. Results showed that birds receiving garlic and natural cocoa powder had significantly (P<0.05) reduced egg and albumen weight as compared to control birds. Hen day production of the birds was also significantly higher than control birds. Egg yolk and serum cholesterol of birds receiving the garlic and natural cocoa powder were significantly (P<0.05) lower than the control. Serum cholesterol levels showed decline in the birds receiving garlic and natural cocoa powder. The least yolk cholesterol level of 160 mg/dl was observed in birds receiving 50g garlic and 50 g natural cocoa powder (Treatment 5). Control birds had an egg cholesterol level of 245.45 mg/dl. It was concluded that incorporating garlic and natural cocoa powder in the diets of laying hens can result in a significant reduction in the egg and serum cholesterol levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=egg" title="egg">egg</a>, <a href="https://publications.waset.org/abstracts/search?q=serum" title=" serum"> serum</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=garlic" title=" garlic"> garlic</a> </p> <a href="https://publications.waset.org/abstracts/30162/egg-yolk-and-serum-cholesterol-reducing-effect-of-garlic-and-natural-cocoa-powder-using-laying-birds-as-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30162.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">767</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">256</span> Alternative Computational Arrangements on g-Group (g &gt; 2) Profile Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20U.%20Ohaegbulem">Emmanuel U.

The pH increase which is mediated by the growing algae also induces phosphorus precipitation and ammonia stripping to the air, and may in addition act disinfecting on the wastewater. Domestic wastewater is ideal for algal growth since it contains high concentrations of all necessary nutrients. The growth limiting factor is rather light, especially at higher latitudes. The most important operational factors for successful wastewater treatment with microalgae are depth, turbulence and hydraulic retention time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgae" title="microalgae">microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title=" nitrogen"> nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=light" title=" light"> light</a>, <a href="https://publications.waset.org/abstracts/search?q=operation" title=" operation"> operation</a>, <a href="https://publications.waset.org/abstracts/search?q=ponds" title=" ponds"> ponds</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a> </p> <a href="https://publications.waset.org/abstracts/15818/wastewater-treatment-using-microalgae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15818.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">478</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">254</span> Portfolio Risk Management Using Quantum Annealing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Doutre">Thomas Doutre</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20De%20Meric%20De%20Bellefon"> Emmanuel De Meric De Bellefon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the application of local-search metaheuristic quantum annealing to portfolio opti- mization.

Therefore, there is need to determine the actual rate of settlement possible in the soil before structures are built on it. This information will help in determining the type of foundation design and the kind of reinforcement that will be necessary in constructions. This paper presents a simplified and a faster approach for determining foundation settlement in any type of soil using real field data acquired from seismic refraction techniques and cone penetration tests. This approach was also able to determine the depth of settlement of each strata of soil.

The weaverbirds are a large family of birds found mostly in Africa, with a few species found in southern Asia and the West Indian Ocean islands. This study assessed the diversity and abundance of weaver birds and their allies within and around Ngel-Nyaki Forest Reserve in Yelwa, Sardauna Local Government Area of Taraba State, Nigeria. A total of 602 weaver birds and allies’ bird species were recorded using the Point Count Line Transect. The data collected during the research period were analyzed using simple percentages, and diversity was calculated using the Shannon Wiener Diversity Index. The fenced (ungrazed area) was more abundant with 351 individuals while the unfenced (grazed area) was less abundant with 251 individuals recorded. In the fenced (ungrazed area), Yellow Bishop (Euplectes capensis) had the highest abundance of (102; 29.01%), followed by Village Weaver (Ploceus cucullatus) (80; 22.79%), then Vieillot's Black Weaver (Ploceus nigerrimus) (40; 11.42%), Red-collard Widowbird (Ploceus ardens) (6; 1.71%), Dark-backed Weaver (5; 1.42%) and the least was Hartlaub Marsh Widowbird (1; 0.28%) while in the unfenced (grazed area), the Village weaver (Ploceus cucullatus) (85; 33.86%) was the most abundant, followed by Spectacled Weaver (Ploceus ocularis) (36; 14.34%), then Yellow Bishop (Euplectes capensis) (30; 11.95%), Baglefecht Weaver (Ploceus baglafecht) (23; 9.16%), Bannerman’s Weaver (Ploceus bannermani) (17; 6.77%) and the least was Yellow-mantled Widowbird (Euplectes macroura) (5; 1.99%). In terms of diversity, there were more weaver bird species in the fenced area with a Shannon Wiener Diversity Index of (Hˈ 2.03417) than in the unfenced area with a Shannon Wiener Diversity Index of (Hˈ 1.862671). The Shannon Wiener Diversity Index in both fenced and unfenced areas is significant. There was more abundance of bird species in the fenced area than in the unfenced area of the Forest Reserve. Thorough research should be conducted on the abundance and diversity of weavers and their allies because we were only able to access 4 km2 out of 46 km2 of land available, according to the Annual Report of Ngel-Nyaki Forest Reserve of 2020. It shows that there are many species of weaver birds and their allies, such as the Black-billed Weaver (Ploceus melanogaster) and the Red-billed Quelea (Quelea quelea), which are available within the reserve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abundance" title="abundance">abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=weaver%20birds" title=" weaver birds"> weaver birds</a>, <a href="https://publications.waset.org/abstracts/search?q=allies" title=" allies"> allies</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngel-Nyaki" title=" Ngel-Nyaki"> Ngel-Nyaki</a> </p> <a href="https://publications.waset.org/abstracts/179089/assessment-of-weaver-birds-and-their-allies-within-and-around-ngel-nyaki-forest-reserve-yelwa-sardauna-lga-taraba-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179089.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">71</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">245</span> Terraria AI: YOLO Interface for Decision-Making Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Barrantes%20Chaves">Emmanuel Barrantes Chaves</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernesto%20Rivera%20Alvarado"> Ernesto Rivera Alvarado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a method to enable agents for the Terraria game to evaluate algorithms commonly used in general video game artificial intelligence competitions.

This advancement might also have repercussions for institutions, families, and politics, so modifying the norms and establishing new societal ideals. In the following paragraphs, it will explore how gender roles in the family have changed over time, how this has affected consumption, and how marketing has been influenced by these changes. It was decided to use the empirical research method, which led to several discoveries, one of which was that marketing in the pre-modern era was predicated on metanarratives and gender stereotypes. However, these aspects of marketing have undergone significant transformations in the post-modern era, which led to the formation of an assumption regarding what future marketing trends will be like. In spite of the fact that post-modern marketing methods have a number of drawbacks, it was suggested that these strategies be embraced and updated in the future in order to expand consumer bases and target audiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marketing" title="Marketing">Marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=Gender%20Roles" title=" Gender Roles"> Gender Roles</a>, <a href="https://publications.waset.org/abstracts/search?q=Advertising" title=" Advertising"> Advertising</a>, <a href="https://publications.waset.org/abstracts/search?q=Decentralisation" title=" Decentralisation"> Decentralisation</a>, <a href="https://publications.waset.org/abstracts/search?q=Fragmentation" title=" Fragmentation"> Fragmentation</a> </p> <a href="https://publications.waset.org/abstracts/154407/marketing-implications-and-the-dynamics-of-changing-gender-roles-in-families" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154407.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">116</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">243</span> Potentials of Underutilised Crops in the Nigerian Farming Systems for Sustainable Food Production and Economic Empowerment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jesse%20Silas%20Mshelia">Jesse Silas Mshelia</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Mamman%20Degri"> Michael Mamman Degri</a>, <a href="https://publications.waset.org/abstracts/search?q=Akeweta%20Emmanuel%20Samaila"> Akeweta Emmanuel Samaila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This review was conducted in the North-Eastern part of Nigeria where there are a lot of challenges of poverty and low level of productivity of farmlands as a result of dwindling soil fertility and dependence on crops that are not so much adopted to the soil and climatic condition and the prevailing farming systems of the area which is predominantly mixed cropping. The crops that are neglected are well fitted into this system of production and yield better with the low level of input and management and give a higher profit margin. These crops, the farmers have mastered the production techniques, but do not have the scientific knowledge to improve the quality of the seed and the products hence need the intervention of modern technologies to benefit maximally from the full potentials of these crops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=farming%20systems" title="farming systems">farming systems</a>, <a href="https://publications.waset.org/abstracts/search?q=neglected%20crops" title=" neglected crops"> neglected crops</a>, <a href="https://publications.waset.org/abstracts/search?q=potentials" title=" potentials"> potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=underutilised" title=" underutilised"> underutilised</a> </p> <a href="https://publications.waset.org/abstracts/52113/potentials-of-underutilised-crops-in-the-nigerian-farming-systems-for-sustainable-food-production-and-economic-empowerment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52113.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">375</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">242</span> Microwave Production of Geopolymers Using Fluidized Bed Combustion Bottom Ash</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osholana%20Tobi%20Stephen">Osholana Tobi Stephen</a>, <a href="https://publications.waset.org/abstracts/search?q=Rotimi%20Emmanuel%20Sadiku"> Rotimi Emmanuel Sadiku</a>, <a href="https://publications.waset.org/abstracts/search?q=Bilainu%20Oboirien.o"> Bilainu Oboirien.o</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fluidized bed combustion (FBC) is a clean coal technology used in the combustion of low-grade coals for power generation. The production of large solid wastes such as bottom ashes from this process is a problem. The bottom ash contains some toxic elements which can leach out soils and contaminate surface and ground water; for this reason, they can neither be disposed in landfills nor lagoons anymore. The production of geopolymers from bottom ash for structural and concrete applications is an option for their disposal. In this study, the waste bottom ash obtained from the combustion of three low grade South African coals in a bubbling fluidized bed reactor was used to produce geopolymers. The geopolymers were cured in a household microwave. The results showed that the microwave curing enhanced the reactivity and strength of the geopolymers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bottom%20ash" title="bottom ash">bottom ash</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed%20combustion%20%28FBC%29%20geopolymer" title=" fluidized bed combustion (FBC) geopolymer"> fluidized bed combustion (FBC) geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/49851/microwave-production-of-geopolymers-using-fluidized-bed-combustion-bottom-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49851.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">315</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">241</span> Cross-Cultural Evangelism a Necessity in Contemporary Times: A Case Study of Mission of Diocese on the Niger Anglican Communion to Togo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nnatuanya%20Chinedu%20Emmanuel">Nnatuanya Chinedu Emmanuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this research is to point out the importance of mission across nations, tribes, and languages.

This trend is to continue until the entire power grids are fully connected so they can be monitored and controlled in real-time. Much achievement has been made in the synchrophasor technology development and deployment, and much more are yet to be achieved. Real-time power grid control and protection potentials of synchrophasor are yet to be explored. It is of necessity that researchers keep in view the various challenges that still need to be overcome in expanding the frontiers of synchrophasor technology. This paper outlines the major challenges that should be dealt with in order to achieve the goal of total power grid visualization, monitoring and control using synchrophasor technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20power%20grid" title="electric power grid">electric power grid</a>, <a href="https://publications.waset.org/abstracts/search?q=grid%20visualization" title=" grid visualization"> grid visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=phasor%20measurement%20unit" title=" phasor measurement unit"> phasor measurement unit</a>, <a href="https://publications.waset.org/abstracts/search?q=synchrophasor" title=" synchrophasor"> synchrophasor</a> </p> <a href="https://publications.waset.org/abstracts/34833/challenges-with-synchrophasor-technology-deployments-in-electric-power-grids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34833.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">556</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">238</span> Distribution Network Optimization by Optimal Placement of Photovoltaic-Based Distributed Generation: A Case Study of the Nigerian Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edafe%20Lucky%20Okotie">Edafe Lucky Okotie</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Osawaru%20Omosigho"> Emmanuel Osawaru Omosigho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the impacts of the introduction of distributed energy generation (DEG) technology into the Nigerian power system as an alternative means of energy generation at distribution ends using Otovwodo 15 MVA, 33/11kV injection substation as a case study.

The reactions were followed by both infrared and nuclear magnetic resonance. Physico-chemical characterisation of the samples for iodine value (IV), acid value (AV), saponification value (SV) and hydroxyl value (HV) were carried out. Thermal transitions of the products were studied by heating 5 mg of the sample from 20ºC to 800ºC and then cooling down to -500ºC on a differential scanning calorimeter (DSC). The preparation of epoxylpolyol and polyurethane from Jatropha curcas oil was smooth and efficient. Results of film and solubility properties revealed that coatings of Jatropha curcas epoxy-polyurethanes performed better with increased loading of toluylene 2, 4-diisocyanate (TDI) up to 2 wt% while their solvent resistance decreased beyond a TDI loading of 1.2 wt%.

The study findings show that the number of hidden states and infection rates within and across the two geographical areas differ according to blood type. <p
