A subgroup of these called flavanones display a wide range of biological activities, and they also have an important physiological role in plants. The ionic liquid (ILs) are compounds consisting of an organic cation with an organic or inorganic anion. Due to its unique properties such as high electrical conductivity, wide temperature range of the liquid state, thermal and electrochemical stability, high ionic density and low volatility and flammability, are considered as ecological solvents in organic synthesis, catalysis, electrolytes in accumulators, and electrochemistry, non-volatile plasticizers, and chemical separation. It was synthesized ionic liquid IL 1-butyl-3-methylimidazolium bromide free-solvent and used as reaction medium for flavanones synthesis, under several reaction conditions of temperature, time and production. The obtained compounds were analyzed by melting point, elemental analysis, IR and UV-vis spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1-butyl-3-methylimidazolium%20bromide" title="1-butyl-3-methylimidazolium bromide">1-butyl-3-methylimidazolium bromide</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=free-solvent" title=" free-solvent"> free-solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=IR%20spectroscopy" title=" IR spectroscopy"> IR spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/108195/ionic-liquid-1-butyl-3-methylimidazolium-bromide-as-reaction-medium-for-the-synthesis-of-flavanones-under-solvent-free-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108195.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">120</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">72</span> Scoping Review of Biological Age Measurement Composed of Biomarkers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Alejandro%20Esp%C3%ADndola-Fern%C3%A1ndez">Diego Alejandro Espíndola-Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Mar%C3%ADa%20Posada-Cano"> Ana María Posada-Cano</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagn%C3%B3var%20Aristiz%C3%A1bal-Ocampo"> Dagnóvar Aristizábal-Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Alberto%20Gallo-Villegas"> Jaime Alberto Gallo-Villegas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: With the increase in life expectancy, aging has been subject of frequent research, and therefore multiple strategies have been proposed to quantify the advance of the years based on the known physiology of human senescence. For several decades, attempts have been made to characterize these changes through the concept of biological age, which aims to integrate, in a measure of time, structural or functional variation through biomarkers in comparison with simple chronological age. The objective of this scoping review is to deepen the updated concept of measuring biological age composed of biomarkers in the general population and to summarize recent evidence to identify gaps and priorities for future research. Methods: A scoping review was conducted according to the five-phase methodology developed by Arksey and O'Malley through a search of five bibliographic databases to February 2021. Original articles were included with no time or language limit that described the biological age composed of at least two biomarkers in those over 18 years of age. Results: 674 articles were identified, of which 105 were evaluated for eligibility and 65 were included with information on the measurement of biological age composed of biomarkers. Articles from 1974 of 15 nationalities were found, most observational studies, in which clinical or paraclinical biomarkers were used, and 11 different methods described for the calculation of the composite biological age were informed. The outcomes reported were the relationship with the same measured biomarkers, specified risk factors, comorbidities, physical or cognitive functionality, and mortality. Conclusions: The concept of biological age composed of biomarkers has evolved since the 1970s and multiple methods of its quantification have been described through the combination of different clinical and paraclinical variables from observational studies. Future research should consider the population characteristics, and the choice of biomarkers against the proposed outcomes to improve the understanding of aging variables to direct effective strategies for a proper approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20age" title="biological age">biological age</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20aging" title=" biological aging"> biological aging</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a>, <a href="https://publications.waset.org/abstracts/search?q=senescence" title=" senescence"> senescence</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a> </p> <a href="https://publications.waset.org/abstracts/144297/scoping-review-of-biological-age-measurement-composed-of-biomarkers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144297.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">188</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">71</span> A Block World Problem Based Sudoku Solver</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luciana%20Abednego">Luciana Abednego</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Nugraheni"> Cecilia Nugraheni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many approaches proposed for solving Sudoku puzzles.

The idea is that the waste stream from edible oil industry, after the separation of oil by using skimmers is subjected to microfiltration and the obtained permeate can be used again in the production process. The wastewater from edible oil industry was used for the microfiltration. For the microfiltration of this effluent a tubular membrane was used with a pore size of 200 nm at transmembrane pressure in range up to 3 bar and in range of flow rate up to 300 L/h. Box–Behnken design was selected for the experimental work and the responses considered were permeate flux and chemical oxygen demand (COD) reduction. The reduction of the permeate COD was in the range 40-60% according to the feed. The highest permeate flux achieved during the process of microfiltration was 160 L/m<sup>2</sup>h. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membrane" title="ceramic membrane">ceramic membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20oil" title=" edible oil"> edible oil</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiltration" title=" microfiltration"> microfiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/40236/edible-oil-industry-wastewater-treatment-by-microfiltration-with-ceramic-membrane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40236.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">300</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">69</span> Newly Developed Epoxy-Polyol and Epoxy- Polyurethane from Renewable Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akintayo%20Emmanuel%20Temitope">Akintayo Emmanuel Temitope</a>, <a href="https://publications.waset.org/abstracts/search?q=Akintayo%20Cecilia%20Olufunke"> Akintayo Cecilia Olufunke</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziegler%20Thomas"> Ziegler Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-polyols are important components in polyurethane industries. The preliminary studies into the synthesis of bio-polyol products (epoxy-polyol and epoxyl-polyurethanes) from Jatropha curcas were investigated. 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%. DSC analysis shows the epoxy-polyurethane to be less stable compared to the epoxy-polyol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthesis" title="synthesis">synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy-polyol" title=" epoxy-polyol"> epoxy-polyol</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy-polyurethane" title=" epoxy-polyurethane"> epoxy-polyurethane</a>, <a href="https://publications.waset.org/abstracts/search?q=jatropha%20curcas%20oil" title=" jatropha curcas oil"> jatropha curcas oil</a> </p> <a href="https://publications.waset.org/abstracts/6080/newly-developed-epoxy-polyol-and-epoxy-polyurethane-from-renewable-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6080.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">421</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">68</span> Exploring the Impact of Location on Urban and Peri-Urban Farming: A Case Study from Lusaka, Zambia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Elisabeth%20F%C3%A5hraeus">Cecilia Elisabeth Fåhraeus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2016, this author conducted a study on agricultural livelihoods in urban and peri-urban low-income settings in Lusaka, Zambia. The overarching aim was to determine the impact of physical space on agricultural activities, with a particular emphasis on geographical distinctions between urban and peri-urban environments. Agricultural activities among the areas’ residents were mapped through questionnaires, interviews and observations, and included variables such as type of activity and product; degree of marketization; inputs; location of production, storage and vending; labour distribution; production constraints, and associated mobility patterns, among others. The study confirmed that spatial idiosyncrasies of urban and peri-urban environments both enabled and constrained agricultural activity, but not always as anticipated. There were also cross-cutting issues on which physical space appeared to have a limited impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20production%20systems" title="agricultural production systems">agricultural production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=geography" title=" geography"> geography</a>, <a href="https://publications.waset.org/abstracts/search?q=low-income%20settlements" title=" low-income settlements"> low-income settlements</a>, <a href="https://publications.waset.org/abstracts/search?q=Lusaka" title=" Lusaka"> Lusaka</a>, <a href="https://publications.waset.org/abstracts/search?q=peri-urban" title=" peri-urban"> peri-urban</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a> </p> <a href="https://publications.waset.org/abstracts/61787/exploring-the-impact-of-location-on-urban-and-peri-urban-farming-a-case-study-from-lusaka-zambia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61787.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">334</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">67</span> Meeting the Parents on Facebook : A Case Study of the Swedish Social Insurance Agency’s Social Media Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Teljas">Cecilia Teljas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many government agencies use social media to supplement their traditional communication channels. Government agencies are typically risk-averse, which makes social media practices problematic. However, this case study of the social media use of the Swedish social insurance agency shows considerable bi-directional communication between the agency and the public. On one hand, the agency’s aims, strategies, ways of working and experiences related to its social media communication practice are analyzed. On the other hand, the communication by both the agency and the public is studied on one of the agency’s Facebook pages. The results showed that it is possible for an agency to provide relevant and accurate information in real-time in social media if identifying and addressing different segments separately. Furthermore, as a result of context adaption this communication was rather informal and the practice can be considered to manifest positive democratic effects due to the increased availability and inclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-government" title="e-government">e-government</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20analysis" title=" discourse analysis"> discourse analysis</a> </p> <a href="https://publications.waset.org/abstracts/37220/meeting-the-parents-on-facebook-a-case-study-of-the-swedish-social-insurance-agencys-social-media-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37220.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">430</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">66</span> Hand Hygiene Habits of Ghanaian Youths in Accra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Amponsem-Boateng">Cecilia Amponsem-Boateng</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20B.%20Oppong"> Timothy B.

Since the hand is in constant contact with fomites which have been proven to be mostly contaminated, building hand hygiene habits is essential for the prevention of infection. This research was conducted to assess the hand hygiene habits of Ghanaian youths in Accra. This study used a survey as a quantitative method of research. The findings of the study revealed that out of the 254 participants who fully answered the questionnaire, 22% had the habit of washing their hands after outings while only 51.6% had the habit of washing their hands after using the bathroom. However, about 60% of the participants said they sometimes ate with their hands while 28.9% had the habit of eating with the hand very often, a situation that put them at risk of infection from their hands since some participants had poor handwashing habits; prompting the need for continuous education on hand hygiene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene" title="hand hygiene">hand hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene%20habit" title=" hand hygiene habit"> hand hygiene habit</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20washing" title=" hand washing"> hand washing</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20sanitizer%20use" title=" hand sanitizer use"> hand sanitizer use</a> </p> <a href="https://publications.waset.org/abstracts/159334/hand-hygiene-habits-of-ghanaian-youths-in-accra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159334.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">108</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">65</span> Agro-Industrial Waste as a Source of Catalyst Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brenda%20Cecilia%20Ledesma">Brenda Cecilia Ledesma</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Beltramone"> Andrea Beltramone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work deals with the bio-waste valorization approach for catalyst development, the use of products derived from biomass as raw material and the obtaining of biofuels.

Subsequently, the metallic nanoparticles were deposited in the activated carbon to use the solid as a catalytic material for the hydrogenation of HMF to 2,5-DMF. The catalyst presented an excellent performance for biofuels generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orange%20peel" title="orange peel">orange peel</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-waste%20valorization" title=" bio-waste valorization"> bio-waste valorization</a>, <a href="https://publications.waset.org/abstracts/search?q=platinum" title=" platinum"> platinum</a>, <a href="https://publications.waset.org/abstracts/search?q=iridium" title=" iridium"> iridium</a>, <a href="https://publications.waset.org/abstracts/search?q=5-hydroxymethylfurfural" title="5-hydroxymethylfurfural">5-hydroxymethylfurfural</a> </p> <a href="https://publications.waset.org/abstracts/142523/agro-industrial-waste-as-a-source-of-catalyst-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142523.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">196</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">64</span> iCCS: Development of a Mobile Web-Based Student Integrated Information System using Hill Climbing Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Cecilia%20G.%20Cantos">Maria Cecilia G.

The system was developed to help the students to check their academic result, manage profile, make self-enlistment and assist the students to manage their academic status that can be viewed also in mobile phones. Developing class schedules in a traditional way is a long process that involves making many numbers of choices. With Hill Climbing Algorithm, however, the process of class scheduling, particularly with regards to courses to be taken by the student aligned with the curriculum, can perform these processes and end up with an optimum solution. The proponent used Rapid Application Development (RAD) for the system development method. The proponent also used the PHP as the programming language and MySQL as the database. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hill%20climbing%20algorithm" title="hill climbing algorithm">hill climbing algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20system" title=" integrated system"> integrated system</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20web-based" title=" mobile web-based"> mobile web-based</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20information%20system" title=" student information system"> student information system</a> </p> <a href="https://publications.waset.org/abstracts/2011/iccs-development-of-a-mobile-web-based-student-integrated-information-system-using-hill-climbing-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2011.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">385</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">63</span> Digitalization in Aggregate Quarries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Eugenio%20Ortiz">José Eugenio Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Plaza"> Pierre Plaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Josefa%20Herrero"> Josefa Herrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Iv%C3%A1n%20Cabria"> Iván Cabria</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Blanco"> José Luis Blanco</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Gavilanes"> Javier Gavilanes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Ignacio%20Escavy"> José Ignacio Escavy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignacio%20L%C3%B3pez-Cilla"> Ignacio López-Cilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginia%20Yag%C3%BCe"> Virginia Yagüe</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20P%C3%A9rez"> César Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Rodr%C3%ADguez"> Silvia Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Rico"> Jorge Rico</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Serrano"> Cecilia Serrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Bernat"> Jesús Bernat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of Artificial Intelligence services in mining processes, specifically in aggregate quarries, is facilitating automation and improving numerous aspects of operations.

This is a couple with the low income of most residents and the government's policy of free basic water which is making rural water provision very difficult. With regard to cartage, the results reveal that the majority (84.4%) of the population covers distances of about 1kilometre to fetch water, and 15.6% travel up kilometer to access water facilities. This means that the water sources are located very far from households, outside the officially legislated array of 200metres. These are many reasons to account for this situation. Firstly, this implies that there are inadequate stand pipes to cater for all the homesteads scattered across the rugged terrain of OR Tambo District municipality. Secondly, and following from the first explanation, it would be seen that funding that is made available is not adequate, or is not efficiently spent on the targeted projects. The situation in the rural areas of South Africa is fraught with cumbersome complexity when it comes to service delivery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water" title="water">water</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=government" title=" government"> government</a>, <a href="https://publications.waset.org/abstracts/search?q=rural" title=" rural"> rural</a> </p> <a href="https://publications.waset.org/abstracts/57423/government-intervention-strategies-in-providing-water-to-rural-communities-in-the-o-r-tambo-district-municipality-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57423.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">286</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">61</span> Kinetics, Equilibrium and Thermodynamics of the Adsorption of Triphenyltin onto NanoSiO₂/Fly Ash/Activated Carbon Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olushola%20S.%20Ayanda">Olushola S.

Equilibrium adsorption data were analyzed using Langmuir, Freundlich, Temkin and Dubinin–Radushkevich (D-R) isotherm models. Pseudo ﬁrst- and second-order, Elovich and fractional power models were applied to test the kinetic data and in order to understand the mechanism of adsorption, thermodynamic parameters such as ΔG°, ΔSo and ΔH° were also calculated. The results showed a very good compliance with pseudo second-order equation while the Freundlich and D-R models fit the experiment data. Approximately 99.999 % TPT was removed from the initial concentration of 100 mg/L TPT at 80oC, contact time of 60 min, pH 8 and a stirring speed of 200 rpm. Thus, nanoSiO2/fly ash/activated carbon composite could be used as effective adsorbent for the removal of TPT from contaminated water and wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isotherm" title="isotherm">isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoSiO%E2%82%82%2Ffly%20ash%2Factivated%20carbon%20composite" title=" nanoSiO₂/fly ash/activated carbon composite"> nanoSiO₂/fly ash/activated carbon composite</a>, <a href="https://publications.waset.org/abstracts/search?q=tributyltin" title=" tributyltin"> tributyltin</a> </p> <a href="https://publications.waset.org/abstracts/52321/kinetics-equilibrium-and-thermodynamics-of-the-adsorption-of-triphenyltin-onto-nanosio2fly-ashactivated-carbon-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52321.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">295</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">60</span> The Effect of Virtual Reality Meditation on Science Education Students Academic Achievement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Obi%20Nja">Cecilia Obi Nja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to investigate the effect of virtual reality meditation on science education undergraduate students’ academic achievement. It was in two parts: it compared the impact of meditation via virtual reality against video, as accessed by students’ mean scores. Secondly, the study examined the usefulness of meditation on the overall well-being of students through video or virtual reality. All the science education undergraduate students of the University of Calabar constituted the population of the study. Two research questions and hypotheses were formulated to guide the study. The study employed a pretest–posttest design with the participants being randomly assigned to two groups. The sample size was 120. Analysis of covariance (ANCOVA) results showed that virtual reality meditation had a significantly higher benefit than video meditation. The results of the analysis also indicated that undergraduate students with both meditation techniques employed had decreased pre-exam anxiety. It was concluded that virtual reality meditation plays a major role in students’ academic achievement and test anxiety levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consciousness" title="consciousness">consciousness</a>, <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=meditation" title=" meditation"> meditation</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a> </p> <a href="https://publications.waset.org/abstracts/177006/the-effect-of-virtual-reality-meditation-on-science-education-students-academic-achievement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Breast Cancer Mortality and Comorbidities in Portugal: A Predictive Model Built with Real World Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cec%C3%ADlia%20M.%20Ant%C3%A3o">Cecília M.

This retrospective observational study aimed at identifying comorbidities associated with BC female patients admitted to Portuguese public hospitals (2010-2018), investigating the effect of comorbidities on BC mortality rate, and building a predictive model using logistic regression. Results showed that the BC mortality in Portugal decreased in this period and reached 4.37% in 2018. Adjusted odds ratio indicated that secondary malignant neoplasms of liver, of bone and bone marrow, congestive heart failure, and diabetes were associated with an increased chance of dying from breast cancer. Although the Lisbon district (the most populated area) accounted for the largest percentage of BC patients, the logistic regression model showed that, besides patient’s age, being resident in Bragança, Castelo Branco, or Porto districts was directly associated with an increase of the mortality rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=comorbidities" title=" comorbidities"> comorbidities</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression" title=" logistic regression"> logistic regression</a>, <a href="https://publications.waset.org/abstracts/search?q=adjusted%20odds%20ratio" title=" adjusted odds ratio"> adjusted odds ratio</a> </p> <a href="https://publications.waset.org/abstracts/143667/breast-cancer-mortality-and-comorbidities-in-portugal-a-predictive-model-built-with-real-world-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Role of GM1 in the Interaction between Amyloid Prefibrillar Oligomers of Salmon Calcitonin and Model Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristiano%20Giordani">Cristiano Giordani</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Diociaiuti"> Marco Diociaiuti</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Bombelli"> Cecilia Bombelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Zanetti-Polzi"> Laura Zanetti-Polzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Belfiore"> Marcello Belfiore</a>, <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Fioravanti"> Raoul Fioravanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianfranco%20Macchia"> Gianfranco Macchia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigated induced functional effects by evaluating Ca2+-influx in liposomes and cell viability in HT22-DIFF neurons. Only solutions rich in unstructured Prefibrillar-Oligomers (PFOs) were able, in the presence of Monosialoganglioside-GM1 (GM1), to induce Ca2+-influx and were also neurotoxic, suggesting a correlation between the two phenomena. Thus, in the presence of GM1, we investigated the protein conformation and liposome modification due to the interaction. Circular Dichroism showed that GM1 fostered the formation of β-structures and Energy Filtered-Transmission Electron Microscopy that PFOs formed “amyloid-channels” as reported for Aβ. We speculate that electrostatic forces occurring between the positive PFOs and negative GM1 drive the initial binding, while the hydrophobic profile of the flexible PFO is responsible for the subsequent pore formation. Conversely, the rigid β-structured mature/fibers (MFs) and proto-fibers (PFs) were unable to induce membrane damage and Ca2+- influx. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloid%20proteins" title="amyloid proteins">amyloid proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=neurotoxicity" title=" neurotoxicity"> neurotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid-rafts" title=" lipid-rafts"> lipid-rafts</a>, <a href="https://publications.waset.org/abstracts/search?q=GM1" title=" GM1"> GM1</a> </p> <a href="https://publications.waset.org/abstracts/118119/role-of-gm1-in-the-interaction-between-amyloid-prefibrillar-oligomers-of-salmon-calcitonin-and-model-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118119.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">189</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> An Analysis of How Students Perceive Their Self-Efficacy in Online Speaking Classes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heny%20Hartono">Heny Hartono</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Titiek%20Murniati"> Cecilia Titiek Murniati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The pandemic has given teachers and students no other choice but having full online learning. In such an emergency situation as the time of the covid-19 pandemic, the application of LMS (Learner Management System) in higher education is the most reasonable solution for students and teachers. In fact, the online learning requires all elements of a higher education systems, including the human resources, infrastructure, and supporting systems such as the application, server, and stable internet connection. The readiness of the higher education institution in preparing the online system may secure those who are involved in the online learning process. It may also result in students’ self-efficacy in online learning. This research aimed to investigate how students perceive their self-efficacy in online English learning, especially in speaking classes which is considered as a productive language skill. This research collects qualitative data with narrative inquiry involving 25 students of speaking classes as the respondents. The results of this study show that students perceive their self-efficacy in speaking online classes as not very high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title="self-efficacy">self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a>, <a href="https://publications.waset.org/abstracts/search?q=speaking%20class" title=" speaking class"> speaking class</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20students" title=" college students"> college students</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a> </p> <a href="https://publications.waset.org/abstracts/152039/an-analysis-of-how-students-perceive-their-self-efficacy-in-online-speaking-classes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152039.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">99</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> Spatial Analysis of Park and Ride Users’ Dynamic Accessibility to Train Station: A Case Study in Perth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ting%20%28Grace%29%20Lin">Ting (Grace) Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianhong%20%28Cecilia%29%20Xia"> Jianhong (Cecilia) Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Todd%20Robinson"> Todd Robinson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accessibility analysis, examining people’s ability to access facilities and destinations, is a fundamental assessment for transport planning, policy making, and social exclusion research. Dynamic accessibility which measures accessibility in real-time traffic environment has been an advanced accessibility indicator in transport research. It is also a useful indicator to help travelers to understand travel time daily variability, assists traffic engineers to monitor traffic congestions, and finally develop effective strategies in order to mitigate traffic congestions. This research involved real-time traffic information by collecting travel time data with 15-minute interval via the TomTom<sup>®</sup> API. A framework for measuring dynamic accessibility was then developed based on the gravity theory and accessibility dichotomy theory through space and time interpolation. Finally, the dynamic accessibility can be derived at any given time and location under dynamic accessibility spatial analysis framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20accessibility" title="dynamic accessibility">dynamic accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20spot" title=" hot spot"> hot spot</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20research" title=" transport research"> transport research</a>, <a href="https://publications.waset.org/abstracts/search?q=TomTom%C2%AE%20API" title=" TomTom® API"> TomTom® API</a> </p> <a href="https://publications.waset.org/abstracts/66401/spatial-analysis-of-park-and-ride-users-dynamic-accessibility-to-train-station-a-case-study-in-perth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66401.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">392</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> The Public Law Studies: Relationship Between Accountability, Environmental Education and Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aline%20Alves%20Bandeira">Aline Alves Bandeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Pedro%20Lima"> Luís Pedro Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Cec%C3%ADlia%20de%20Paula%20Silva"> Maria Cecília de Paula Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20de%20Viveiros%20Tavares"> Paulo Henrique de Viveiros Tavares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the study of public policies regarding management efficiency is essential. Public policies are about what governments do or do not do, being an area that has grown worldwide, contributing through the knowledge of technologies and methodologies that monitor and evaluate the performance of public administrators. The information published on official government websites needs to provide for transparency and responsiveness of managers. Thus, transparency is a primordial factor for the execution of Accountability, providing, in this way, services to the citizen with the expansion of transparent, efficient, democratic information and that value administrative eco-efficiency. The ecologically balanced management of a Smart City must optimize environmental education, building a fairer society, which brings about equality in the use of quality environmental resources. Smart Cities add value in the construction of public management, enabling interaction between people, enhancing environmental education and the practical applicability of administrative eco-efficiency, fostering economic development and improving the quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accountability" title="accountability">accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title=" environmental education"> environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20public%20administration" title=" new public administration"> new public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a> </p> <a href="https://publications.waset.org/abstracts/140750/the-public-law-studies-relationship-between-accountability-environmental-education-and-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140750.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Bioproduction of Phytohormones by Liquid Fermentation Using a Mexican Strain of Botryodiplodia theobromae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laredo%20Alcal%C3%A1%20Elan%20I%C3%B1aky">Laredo Alcalá Elan Iñaky</a>, <a href="https://publications.waset.org/abstracts/search?q=Hernandez%20Castillo%20Daniel"> Hernandez Castillo Daniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Martinez%20Hernandez%20Jos%C3%A9%20Luis"> Martinez Hernandez José Luis</a>, <a href="https://publications.waset.org/abstracts/search?q=Arredondo%20Valdes%20Roberto"> Arredondo Valdes Roberto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonzalez%20Gallegos%20Esmeralda"> Gonzalez Gallegos Esmeralda</a>, <a href="https://publications.waset.org/abstracts/search?q=Anguiano%20Cabello%20Julia%20Cecilia"> Anguiano Cabello Julia Cecilia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant hormones are a group of molecules that control different processes ranging from the growth and development of the plant until their response to biotic and abiotic stresses. In this study, the capacity of production of various phytohormones was evaluated from a strain of Botryodiplodia theobromae by liquid fermentation system using the modified Mierch medium added with a hydrolyzate compound of mead all in a reactor without agitation at 28 °C for 15 days. Quantification of the metabolites was performed using high performance liquid chromatography techniques. The results showed that a microbial broth with at least five different types of plant hormones was obtained: gibberellic acid, zeatin, kinetin, indoleacetic acid and jasmonic acid, the last one was higher than the others metabolites produced. The production of such hormones using a single type of microorganism could be in the future a great alternative to reduce production costs and similarly reduce the use of synthetic chemicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosystem" title="biosystem">biosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20hormones" title=" plant hormones"> plant hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=Botryodiplodia%20theobromae" title=" Botryodiplodia theobromae"> Botryodiplodia theobromae</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/43134/bioproduction-of-phytohormones-by-liquid-fermentation-using-a-mexican-strain-of-botryodiplodia-theobromae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43134.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">404</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> Corporate Governance and Firms` Performance: Evidence from Quoted Firms on the Nigerian Stock Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ogunwole%20Cecilia%20Oluwakemi">Ogunwole Cecilia Oluwakemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahid%20Damilola%20Olanipekun"> Wahid Damilola Olanipekun</a>, <a href="https://publications.waset.org/abstracts/search?q=Omoyele%20Olufemi%20Samuel"> Omoyele Olufemi Samuel</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Ayomitunde%20Aderemi"> Timothy Ayomitunde Aderemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The issues relating to corporate governance in both locally and internationally managed firms cannot be overemphasized because the lack of efficient corporate governance could orchestrate serious problems in any organization. Against this backdrop, this study examines the nexus between corporate governance and performance of firms from 2012 to 2020, using the case study of the Nigerian stock exchange. Consequently, data was collected from forty (40) listed firms on the Nigerian Stock Exchange. The study employed a fixed effect technique of estimation to address the objective of the study. It was discovered from the study that the influence of corporate governance components such as gender diversity, board independence and managerial ownership led to a significant positive impact on the performance of the firms under the investigation. In view of the above finding, this study makes the following recommendations for the policymakers in Nigeria that anytime the goal of the policymakers is the improvement of performance of the listed firms in the Nigerian stock exchange, board independence and a balance in the inclusion of male and female among the board of directors should be encouraged in these firms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate" title="corporate">corporate</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=firms" title=" firms"> firms</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=stock" title=" stock"> stock</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange" title=" exchange"> exchange</a> </p> <a href="https://publications.waset.org/abstracts/145199/corporate-governance-and-firms-performance-evidence-from-quoted-firms-on-the-nigerian-stock-exchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145199.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">179</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> Microfiltration of the Sugar Refinery Wastewater Using Ceramic Membrane with Kenics Static Mixer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zita%20%C5%A0ere%C5%A1">Zita Šereš</a>, <a href="https://publications.waset.org/abstracts/search?q=Ljubica%20Doki%C4%87"> Ljubica Dokić</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikola%20Maravi%C4%87"> Nikola Maravić</a>, <a href="https://publications.waset.org/abstracts/search?q=Dragana%20%20%C5%A0oronja%20Simovi%C4%87"> Dragana Šoronja Simović</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Hodur"> Cecilia Hodur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Nikoli%C4%87"> Ivana Nikolić</a>, <a href="https://publications.waset.org/abstracts/search?q=Biljana%20Pajin"> Biljana Pajin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New environmental regulations and the increasing market preference for companies that respect the ecosystem had encouraged the industry to look after new treatments for its effluents. The sugar industry, one of the largest emitter of environmental pollutants, follows this tendency. Membrane technology is convenient for separation of suspended solids, colloids and high molecular weight materials that are present in a wastewater from the sugar industry. The idea is to microfilter the wastewater, where the permeate passes through the membrane and becomes available for recycle and re-use in the sugar manufacturing process. For microfiltration of this effluent a tubular ceramic membrane was used with a pore size of 200 nm at transmembrane pressure in range of 1 – 3 bars and in range of flow rate of 50 – 150 l/h. Kenics static mixer was used for permeate flux enhancement. Turbidity and suspended solids were removed and the permeate flux was continuously monitored during the microfiltration process. The flux achieved after 90 minutes of microfiltration was in a range of 50-70 L/m2h. The obtained turbidity decrease was in the range of 50-99% and the total amount of suspended solids was removed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membrane" title="ceramic membrane">ceramic membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiltration" title=" microfiltration"> microfiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=permeate%20flux" title=" permeate flux"> permeate flux</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20industry" title=" sugar industry"> sugar industry</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/28798/microfiltration-of-the-sugar-refinery-wastewater-using-ceramic-membrane-with-kenics-static-mixer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28798.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">524</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">51</span> Implementation of the Science Curriculum of the Colleges of Education: Successes and Challenges </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Boakye">Cecilia Boakye</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Ghartey%20Ampiah"> Joseph Ghartey Ampiah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we present a case study in which we explored how the 2007 science curriculum of the colleges of education in Ghana was implemented at W College of Education. Purposive sampling was used to select 13 participants, comprising 2 tutors and 6 teacher trainees from W College of Education and, 5 newly qualified Junior High School (JHS) science teachers who were products of W College. Interviews, observations and content analysis were used to collect data. Using the deductive and inductive analytic approaches, the findings showed that although upgraded laboratories have provided for teaching authentic science at W College of Education, they are rather used to accommodate large classes at the expense of practical activities. The teaching and learning methods used by the tutors do not mirror effectively the objectives of the 2007 science curriculum of the colleges of education. There are challenges such as: (a) lack/inadequate equipment and materials, (b) time constraint, and (c) an examination- oriented curriculum that influence the implementation of the curriculum. Some of the suggestions that were made are that: (a) equipment and materials should be supplied to the colleges to facilitate the proper implementation of the curriculum, and (b) class sizes should be reduced to provide enough room for practical activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=class%20size" title="class size">class size</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching" title=" teaching"> teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum%20implementation" title=" curriculum implementation"> curriculum implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=examination-oriented%20curriculum" title=" examination-oriented curriculum"> examination-oriented curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20time-constraint" title=" teaching and time-constraint"> teaching and time-constraint</a> </p> <a href="https://publications.waset.org/abstracts/48550/implementation-of-the-science-curriculum-of-the-colleges-of-education-successes-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48550.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">50</span> Water Sources in 3 Local Municipalities of O.

This is coupled with the low income of most residents and government's policy which obliges municipalities to supply basic water usually set at 6 kilolitres per month to each household free of charge. During the research, data was collected from three local municipalities of O. R. Tambo, i.e. King Sabata Dalindyebo, Mhlontlo and Ingquza Hill local municipalities. According to the result, significant differences exist between the sources of water in the different local municipalities from which data was collected. The chi square was use to calculated the differences between the sources of water and the calculated critical value of the District Municipality was 18.77 which is more than the stipulated critical value of 3.84. More people in Mhlontlo Local Municipality got water from the taps while a greater percentage of households in King Sataba Dalindyebo and Ingquza hill local municipalities got their water from the natural sources. 77% of the sample population complained that there have been no improvements in water provision because they still get water from natural sources and even the remaining 33% that were getting water from the taps still have to depend on natural sources because the taps are most of the time broken and it takes a long time to fix them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=availability" title="availability">availability</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=sources" title=" sources"> sources</a>, <a href="https://publications.waset.org/abstracts/search?q=supply" title=" supply"> supply</a> </p> <a href="https://publications.waset.org/abstracts/36667/water-sources-in-3-local-municipalities-of-o-r-tambo-district-municipality-south-africa-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36667.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">342</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> Mother Tounge Based Multilingual Education Policy: Voices of Two Cities, 'The Voice of Laguna' </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Velasco">Cecilia Velasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Q."> Q. </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was undertaken to find out the perceived efficiency, appropriateness effectiveness, acceptability and relevance, if at all such exist, of the Mother Tongue Based Multilingual Education Policy under the K-12 Curriculum, as seen by the stakeholders who are directly affected by this policy. The researcher believed that it is right and fitting to get the views and opinions of the people directly involved and/or concerned about this education policy. The results of the study will hopefully guide lawmakers and/or policymakers to fine-tune educational policy or policies. The locale of the study was the DepEd schools in Laguna, (San Pablo City and other nearby cities). The subjects of the study were the teachers (first phase) from the public schools of Department of Education (San Pablo City), in particular and parents (second phase) from nearby cities who are the direct stakeholders of this Policy. To determine the perception of the teachers toward Mother Tongue Based Multilingual Education Policy; its acceptability, efficiency, appropriateness, effectiveness and relevance, factor analysis was used to refine the instrument (questionnaire). To find out the significant difference between the perceptions of the primary and intermediate group of teachers, including those who teach mother tongue and non-mother tongue subjects, t-test of difference between means was employed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DepEd" title="DepEd">DepEd</a>, <a href="https://publications.waset.org/abstracts/search?q=K12%20curriculum" title=" K12 curriculum"> K12 curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=MTBMLE" title=" MTBMLE"> MTBMLE</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders"> stakeholders</a> </p> <a href="https://publications.waset.org/abstracts/53100/mother-tounge-based-multilingual-education-policy-voices-of-two-cities-the-voice-of-laguna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53100.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">300</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">48</span> The Effect of Inhalation of Ylang-ylang Aroma on the Levels of Anxiety of Parents with Hospitalized Toddlers Diagnosed with Pneumonia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Crisostomo%20Hart%20A.">Crisostomo Hart A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cruz%20Anna%20Cecilia%20R."> Cruz Anna Cecilia R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cruz%20Bianca%20Isabelle%20A."> Cruz Bianca Isabelle A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cruz%20John%20Edward%20Ligzurc%20M."> Cruz John Edward Ligzurc M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cruz%20Mikaela%20Denise%20P."> Cruz Mikaela Denise P. </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim/purpose: The researchers aimed to determine the effect of Ylang-ylang aroma in decreasing the anxiety levels of parents with hospitalized toddlers diagnosed with pneumonia.

Meanwhile, despite the fact that Nigeria is an agrarian society, food insecurity and poverty have become the issues of concern among both scholars and policymakers in the recent times. Against this backdrop, this study examined the nexus among agriculture, food security, and poverty reduction in Nigeria from 1990 to 2019 within the framework of the Cointegration and Granger Causality approach. Data was collected from the Central Bank of Nigeria Statistical Bulletin and the World Development Indicators, respectively. The following are the major results that emanated from the study. A long run equilibrium relationship exists among agricultural value added, food production index, and GDP per capita in Nigeria. Similarly, there is a unidirectional causality which flows from food production index to poverty reduction in Nigeria. In the same vein, one way causality flows from poverty reduction to agricultural value added in Nigeria. Consequently, this study makes the following recommendation for the policymakers in Nigeria, and other African countries by extension, that agricultural value added and food production are the important variables that cannot be undermined when poverty reduction occupies the central focus of the policymakers. Therefore, any time these policymakers want to reduce poverty, policies that drive agricultural value added and food production should be embarked upon. Therefore, this study will contribute to the literature by establishing the type of linkage that exists between agriculture, food security, and poverty reduction in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20added" title=" value added"> value added</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20production" title=" food production"> food production</a>, <a href="https://publications.waset.org/abstracts/search?q=GDP%20per%20capita" title=" GDP per capita"> GDP per capita</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/146377/agriculture-food-security-and-poverty-reduction-in-nigeria-cointegration-and-granger-causality-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146377.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">199</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> Smart Energy Consumers: An Empirical Investigation on the Intention to Adopt Innovative Consumption Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Perri">Cecilia Perri</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincenzo%20Corvello"> Vincenzo Corvello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present study is to investigate consumers' determinants of intention toward the adoption of Smart Grid solutions and technologies. Ajzen's Theory of Planned Behaviour (TPB) model is applied and tested to explain the formation of such adoption intention. An exogenous variable, taking into account the resistance to change of individuals, was added to the basic model. The elicitation study allowed obtaining salient modal beliefs, which were used, with the support of literature, to design the questionnaire. After the screening phase, data collected from the main survey were analysed for evaluating measurement model's reliability and validity. Consistent with the theory, the results of structural equation analysis revealed that attitude, subjective norm, and perceived behavioural control positively, which affected the adoption intention. Specifically, the variable with the highest estimate loading factor was found to be the perceived behavioural control, and, the most important belief related to each construct was determined (e.g., energy saving was observed to be the most significant belief linked with attitude). Further investigation indicated that the added exogenous variable has a negative influence on intention; this finding confirmed partially the hypothesis, since this influence was indirect: such relationship was mediated by attitude. Implications and suggestions for future research are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption%20of%20innovation" title="adoption of innovation">adoption of innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=consumers%20behaviour" title=" consumers behaviour"> consumers behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management" title=" energy management"> energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20planned%20behaviour" title=" theory of planned behaviour"> theory of planned behaviour</a> </p> <a href="https://publications.waset.org/abstracts/28707/smart-energy-consumers-an-empirical-investigation-on-the-intention-to-adopt-innovative-consumption-behaviour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28707.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">409</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">45</span> Revealing the Potential of Geotourism and Geoheritage of Gedangsari Area, Yogyakarta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Jatu">Cecilia Jatu</a>, <a href="https://publications.waset.org/abstracts/search?q=Adventino"> Adventino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gedangsari is located in Gunungkidul, Yogyakarta Province, which has several criteria to be used as a new geosite object. The research area is located in the southern mountain zone of Java, composed of 5 rock formations with Oligocene up to Middle Miocene age. The purpose of this study is to reveal the potential of geotourism and the geoheritage to be proposed as a new geosite and to make a geosite map of Gedangsari. The research method used is descriptive data collection and which includes quantitative geological data collection, geotourism, and heritage sites, then supported by petrographic analysis, geological structure, geological mapping, and SWOT analysis. The geological data proved that Gedangsari consists of igneous rock (intrusion), pyroclastic rock, and sediment rock. This condition caused many varieties and particular geomorphological platform. Geotourism that include in Gedangsari are Luweng Sampang Canyon, Gedangsari Bouma Sequence, Watugajah Columnar Joint, Gedangsari Marine Fan Sediment, and Tegalrejo Waterfall. There is also Tegalrejo Village, which can be considered as geoheritage site because of its culture and batik traditional cloth. The results of the SWOT analysis, Gedangsari geosite must be developed and appropriately promoted in order to improve the existence. The development of geosite area will have a significant impact that improve the economic growth of the surrounding community and can be used by the government as base information for sustainable development. In addition, the making of an educational map about the geological conditions and geotourism location of the Gedangsari geosite can increase the people's knowledge about Gedangsari. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gedangsari" title="Gedangsari">Gedangsari</a>, <a href="https://publications.waset.org/abstracts/search?q=geoheritage" title=" geoheritage"> geoheritage</a>, <a href="https://publications.waset.org/abstracts/search?q=geotourism" title=" geotourism"> geotourism</a>, <a href="https://publications.waset.org/abstracts/search?q=geosite" title=" geosite"> geosite</a> </p> <a href="https://publications.waset.org/abstracts/122601/revealing-the-potential-of-geotourism-and-geoheritage-of-gedangsari-area-yogyakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122601.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">123</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> Foodborne Pathogens in Different Types of Milk: From the Microbiome to Risk Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pasquali%20Frederique">Pasquali Frederique</a>, <a href="https://publications.waset.org/abstracts/search?q=Manfreda%20Chiara"> Manfreda Chiara</a>, <a href="https://publications.waset.org/abstracts/search?q=Crippa%20Cecilia"> Crippa Cecilia</a>, <a href="https://publications.waset.org/abstracts/search?q=Indio%20Valentina"> Indio Valentina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ianieri%20Adriana"> Ianieri Adriana</a>, <a href="https://publications.waset.org/abstracts/search?q=De%20Cesare%20Alessandra"> De Cesare Alessandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbiological hazards can be transmitted to humans through milk. In this study, we compared the microbiome composition and presence of foodborne pathogens in organic milk (n=6), organic hay milk (n=6), standard milk (n=6) and high-quality milk (n=6). The milk samples were collected during six samplings between December 2022 to January 2023 and between April and May 2024 to take into account seasonal variations. The 24 milk samples were submitted to DNA extraction and library preparation before shotgun sequencing on the Illumina HiScan™ SQ System platform. The total sequencing output was 600 GB. In all the milk samples, the phyla with the highest relative abundances were Pseudomonadota, Bacillota, Ascomycota, Actinomycetota and Apicomplexa, while the most represented genera were Pseudomonas, Streptococcus, Geotrichum, Acinetobacter and Babesia. The alpha and beta diversity indexes showed a clear separation between the microbiome of high-quality milk and those of the other milk types. Moreover, in the high-quality milk, the relative abundance of Staphylococcus (4.4%), Campylobacter (4.5%), Bacillus (2.5%), Enterococcus (2.4%), Klebsiella (1.3%) and Escherichia (0 .7%) was significantly higher in comparison to other types of milk. On the contrary, the relative abundance of Geotrichum (0.5%) was significantly lower. The microbiome results collected in this study showed significant differences in terms of the relative abundance of bacteria genera, including foodborne pathogen species. These results should be incorporated into risk assessment models tailored to different types of milk. <p class="card-text"><strong>Keywords:</strong> <a
