that are impaired in children with autism spectrum disorder (ASD), such as social interaction and communication. Objective: The study proposes to analyze the development of dialogic skills of a verbal child with ASD after participating in the equine-assisted therapy Step By Step in Communication. Method: This is quantitative and qualitative research through a case study. It refers to a 6 years old child diagnosed with ASD belonging to a group of practitioners of the Brazilian National Equine-Assited-Therapy Association. The Behavioral Observation Protocol (PROC) was used to evaluate communicative skills before and after the intervention, which consisted of 24 sessions once a week. Results: All conversational skills increased their frequency, with participation in dialogue and initiation of interaction. The child also increases the habit of waiting for his turn and answering the interlocutor. The emission of topics not related to conversation and echolalia showed a significant decrease after the intervention. Conclusion: The studied child showed improvement in communicative skills after participating in the equine-assisted therapy Step By Step in Communication. Contributions: This study contributes to a greater understanding of the impact of equine-assisted therapy on the communicative abilities of children with ASD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equine-assisted-therapy" title="equine-assisted-therapy">equine-assisted-therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title=" autism spectrum disorder"> autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20and%20hearing%20sciences" title=" language and hearing sciences"> language and hearing sciences</a> </p> <a href="https://publications.waset.org/abstracts/165060/analysis-of-the-development-of-communicative-skills-after-participating-in-the-equine-assisted-therapy-program-step-by-step-in-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165060.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">81</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> Biochemical Characterization and Structure Elucidation of a New Cytochrome P450 Decarboxylase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Leandro%20Rade">Leticia Leandro Rade</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Silva%20de%20Sousa"> Amanda Silva de Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Suman%20Das"> Suman Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Wesley%20Generoso"> Wesley Generoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayara%20Chagas%20%C3%81vila"> Mayara Chagas Ávila</a>, <a href="https://publications.waset.org/abstracts/search?q=Plinio%20Salmazo%20Vieira"> Plinio Salmazo Vieira</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Bonomi"> Antonio Bonomi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Persinoti"> Gabriela Persinoti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Tyago%20Murakami"> Mario Tyago Murakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Michael%20Makris"> Thomas Michael Makris</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Maria%20Zanphorlin"> Leticia Maria Zanphorlin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alkenes have an economic appeal, especially in the biofuels field, since they are precursors for drop-in biofuels production, which have similar chemical and physical properties to the conventional fossil fuels, with no oxygen in their composition. After the discovery of the first P450 CYP152 OleTJE in 2011, reported with its unique property of decarboxylating fatty acids (FA), by using hydrogen peroxide as a cofactor and producing 1-alkenes as the main product, the scientific and technological interest in this family of enzymes vastly increased. In this context, the present work presents a new decarboxylase (OleTRN) with low similarity with OleTJE (32%), its biochemical characterization, and structure elucidation. As main results, OleTRN presented a high yield of expression and purity, optimum reaction conditions at 35 °C and pH from 6.5 to 8.0, and higher specificity for oleic acid. Besides that, structure-guided mutations were performed and according to the functional characterizations, it was observed that some mutations presented different specificity and chemoselectivity by varying the chain-length of FA substrates from 12 to 20 carbons. These results are extremely interesting from a biotechnological perspective as those characteristics could diversify the applications and contribute to designing better cytochrome P450 decarboxylases. Considering that peroxygenases have the potential activity of decarboxylating and hydroxylating fatty acids and that the elucidation of the intriguing mechanistic involved in the decarboxylation preferential from OleTJE is still a challenge, the elucidation of OleTRN structure and the functional characterizations of OleTRN and its mutants contribute to new information about CYP152. Besides that, the work also contributed to the discovery of a new decarboxylase with a different selectivity profile from OleTJE, which allows a wide range of applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=P450" title="P450">P450</a>, <a href="https://publications.waset.org/abstracts/search?q=decarboxylases" title=" decarboxylases"> decarboxylases</a>, <a href="https://publications.waset.org/abstracts/search?q=alkenes" title=" alkenes"> alkenes</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuels" title=" biofuels"> biofuels</a> </p> <a href="https://publications.waset.org/abstracts/140579/biochemical-characterization-and-structure-elucidation-of-a-new-cytochrome-p450-decarboxylase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140579.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">202</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">70</span> An Architecture Based on Capsule Networks for the Identification of Handwritten Signature Forgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luisa%20Mesquita%20Oliveira%20Ribeiro">Luisa Mesquita Oliveira Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexei%20Manso%20Correa%20Machado"> Alexei Manso Correa Machado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Handwritten signature is a unique form for recognizing an individual, used to discern documents, carry out investigations in the criminal, legal, banking areas and other applications.

Many companies use the techniques of the Toyota Production System, which in a way goes against a better management of supply chain risks. This paper studies key events in some multinationals to analyze the trade-off between the best supply chain risk management techniques and management policies designed to create lean enterprises. The result of a good balance of these actions is the reduction of losses, increased customer trust in the company and better preparedness to face the general risks of a supply chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=just%20in%20time" title="just in time">just in time</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20disruptions" title=" supply chain disruptions"> supply chain disruptions</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/51640/analysis-of-supply-chain-risk-management-strategies-case-study-of-supply-chain-disruptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51640.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">338</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> Using Data from Foursquare Web Service to Represent the Commercial Activity of a City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taras%20Agryzkov">Taras Agryzkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Almudena%20Nolasco-Cirugeda"> Almudena Nolasco-Cirugeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20L.%20Oliver"> Jose L.

A cross-sectional survey was carried out on a sample of two-hundred eighty-seven adults (Mage = 36.04 (12.07); 59.9% females). Participants were recruited online through clickworker and filled in measures on existential concerns, basic psychological needs, attitudes toward COVID-19 vaccines, and vaccine hesitancy for Pfizer-BioNTech and Astrazeneca vaccines separately. Structural equation modelling showed that existential concerns were related to Pfizer-BioNTech and Astrazeneca vaccine hesitancy both directly and indirectly through negative attitudes toward possible side effects of COVID-19 vaccines. The present study has identified several predictive factors relating to the intention to uptake vaccination to protect against COVID-19 in Italy. Specifically, these findings suggest a causal link between existential concerns, attitudes, and vaccine hesitancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=existential%20concerns" title=" existential concerns"> existential concerns</a>, <a href="https://publications.waset.org/abstracts/search?q=Pfizer-BioNTech%20and%20Astrazeneca%20vaccines" title=" Pfizer-BioNTech and Astrazeneca vaccines"> Pfizer-BioNTech and Astrazeneca vaccines</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine%20hesitancy" title=" vaccine hesitancy"> vaccine hesitancy</a> </p> <a href="https://publications.waset.org/abstracts/149591/covid-19-vaccine-hesitancy-the-role-of-existential-concerns-in-individuals-decisions-regarding-the-vaccine-uptake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149591.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">100</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> A Blockchain-Based Protection Strategy against Social Network Phishing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Buccafurri">Francesco Buccafurri</a>, <a href="https://publications.waset.org/abstracts/search?q=Celeste%20Romolo"> Celeste Romolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays phishing is the most frequent starting point of cyber-attack vectors. Phishing is implemented both via email and social network messages. While a wide scientific literature exists which addresses the problem of contrasting email spam-phishing, no specific countermeasure has been so far proposed for phishing included into private messages of social network platforms. Unfortunately, the problem is severe. This paper proposes an approach against social network phishing, based on a non invasive collaborative information-sharing approach which leverages blockchain. The detection method works by filtering candidate messages, by distilling them by means of a distance-preserving hash function, and by publishing hashes over a public blockchain through a trusted smart contract (thus avoiding denial of service attacks). Phishing detection exploits social information embedded into social network profiles to identify similar messages belonging to disjoint contexts. The main contribution of the paper is to introduce a new approach to contrasting the problem of social network phishing, which, despite its severity, received little attention by both research and industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phishing" title="phishing">phishing</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks" title=" social networks"> social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20sharing" title=" information sharing"> information sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain" title=" blockchain"> blockchain</a> </p> <a href="https://publications.waset.org/abstracts/90849/a-blockchain-based-protection-strategy-against-social-network-phishing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90849.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">328</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> Economic Development and New Challenges: Biomass Energy and Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabricia%20G.%20F.%20S.%20Rossato">Fabricia G.

The Compagnie Nationale du Rhone (C.N.R.), which manages the river, has experimented with several control techniques in recent years. Since 2015, 15 experimental plots have been monitored on the banks of a restored river appendix to measure the effect of three control methods: confinement by felt, repeated mowing and the planting of competing species and/or species with allelopathic power: Viburnum opulus, Rhamnus frangula, Sambucus ebulus and Juglans regia. Each year, the number of stems, the number of elderberry plants, the height of the plants and photographs were collected. After six years of monitoring, the results showed that the density of knotweed stems decreased by 50 to 90% on all plots. The control methods are sustainable and are gradually gaining in efficiency. The establishment of native plants coupled with regular manual maintenance can reduce the development of Japanese knotweed. Continued monitoring over the next few years will determine the kinetics of the total eradication (i.e. 0 stem/plot) of the Japanese knotweed by these methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fallopia%20japonica" title="fallopia japonica">fallopia japonica</a>, <a href="https://publications.waset.org/abstracts/search?q=interspecific%20plant%20competition" title=" interspecific plant competition "> interspecific plant competition </a>, <a href="https://publications.waset.org/abstracts/search?q=Rhone%20river" title=" Rhone river"> Rhone river</a>, <a href="https://publications.waset.org/abstracts/search?q=riparian%20trees" title=" riparian trees"> riparian trees</a> </p> <a href="https://publications.waset.org/abstracts/132873/feedback-from-experiments-on-managing-methods-against-japanese-knotweed-on-a-river-appendix-of-the-rhone-between-2015-and-2020" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Comparison of Two Transcranial Magnetic Stimulation Protocols on Spasticity in Multiple Sclerosis - Pilot Study of a Randomized and Blind Cross-over Clinical Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Cristina%20da%20Silva%20Reis">Amanda Cristina da Silva Reis</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Paulino%20Ven%C3%A2ncio"> Bruno Paulino Venâncio</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Theada%20Ferreira"> Cristina Theada Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Fialho%20do%20Prado"> Andrea Fialho do Prado</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucimara%20Guedes%20dos%20Santos"> Lucimara Guedes dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20de%20Souza%20Gravat%C3%A1"> Aline de Souza Gravatá</a>, <a href="https://publications.waset.org/abstracts/search?q=Larissa%20Lima%20Gon%C3%A7alves"> Larissa Lima Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Aparecida%20Ferreira%20Moretto"> Isabella Aparecida Ferreira Moretto</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Carlos%20Ferrari%20Corr%C3%AAa"> João Carlos Ferrari Corrêa</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Ishida%20Corr%C3%AAa"> Fernanda Ishida Corrêa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To compare two protocols of Transcranial Magnetic Stimulation (TMS) on quadriceps muscle spasticity in individuals diagnosed with Multiple Sclerosis (MS). Method: Clinical, crossover study, in which six adult individuals diagnosed with MS and spasticity in the lower limbs were randomized to receive one session of high-frequency (≥5Hz) and low-frequency (≤ 1Hz) TMS on motor cortex (M1) hotspot for quadriceps muscle, with a one-week interval between the sessions. To assess the spasticity was applied the Ashworth scale and were analyzed the latency time (ms) of the motor evoked potential (MEP) and the central motor conduction time (CMCT) of the bilateral quadriceps muscle. Assessments were performed before and after each intervention. The difference between groups was analyzed using the Friedman test, with a significance level of 0.05 adopted. Results: All statistical analyzes were performed using the SPSS Statistic version 26 programs, with a significance level established for the analyzes at p<0.05. Shapiro Wilk normality test. Parametric data were represented as mean and standard deviation for non-parametric variables, median and interquartile range, and frequency and percentage for categorical variables. There was no clinical change in quadriceps spasticity assessed using the Ashworth scale for the 1 Hz (p=0.813) and 5 Hz (p= 0.232) protocols for both limbs. Motor Evoked Potential latency time: in the 5hz protocol, there was no significant change for the contralateral side from pre to post-treatment (p>0.05), and for the ipsilateral side, there was a decrease in latency time of 0.07 seconds (p<0.05 ); for the 1Hz protocol there was an increase of 0.04 seconds in the latency time (p<0.05) for the contralateral side to the stimulus, and for the ipsilateral side there was a decrease in the latency time of 0.04 seconds (p=<0.05), with a significant difference between the contralateral (p=0.007) and ipsilateral (p=0.014) groups. Central motor conduction time in the 1Hz protocol, there was no change for the contralateral side (p>0.05) and for the ipsilateral side (p>0.05). In the 5Hz protocol for the contralateral side, there was a small decrease in latency time (p<0.05) and for the ipsilateral side, there was a decrease of 0.6 seconds in the latency time (p<0.05) with a significant difference between groups (p=0.019). Conclusion: A high or low-frequency session does not change spasticity, but it is observed that when the low-frequency protocol was performed, there was an increase in latency time on the stimulated side, and a decrease in latency time on the non-stimulated side, considering then that inhibiting the motor cortex increases cortical excitability on the opposite side. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title="multiple sclerosis">multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=spasticity" title=" spasticity"> spasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20evoked%20potential" title=" motor evoked potential"> motor evoked potential</a>, <a href="https://publications.waset.org/abstracts/search?q=transcranial%20magnetic%20stimulation" title=" transcranial magnetic stimulation"> transcranial magnetic stimulation</a> </p> <a href="https://publications.waset.org/abstracts/165786/comparison-of-two-transcranial-magnetic-stimulation-protocols-on-spasticity-in-multiple-sclerosis-pilot-study-of-a-randomized-and-blind-cross-over-clinical-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165786.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">62</span> Towards a Security Model against Denial of Service Attacks for SIP Traffic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arellano%20Karina">Arellano Karina</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Avila-Pes%C3%A1ntez"> Diego Avila-Pesántez</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Vaca-C%C3%A1rdenas"> Leticia Vaca-Cárdenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Arellano"> Alberto Arellano</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmen%20Mantilla"> Carmen Mantilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, security threats in Voice over IP (VoIP) systems are an essential and latent concern for people in charge of security in a corporate network, because, every day, new Denial-of-Service (DoS) attacks are developed. These affect the business continuity of an organization, regarding confidentiality, availability, and integrity of services, causing frequent losses of both information and money. The purpose of this study is to establish the necessary measures to mitigate DoS threats, which affect the availability of VoIP systems, based on the Session Initiation Protocol (SIP). A Security Model called MS-DoS-SIP is proposed, which is based on two approaches. The first one analyzes the recommendations of international security standards. The second approach takes into account weaknesses and threats. The implementation of this model in a VoIP simulated system allowed to minimize the present vulnerabilities in 92% and increase the availability time of the VoIP service into an organization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denial-of-Service%20SIP%20attacks" title="Denial-of-Service SIP attacks">Denial-of-Service SIP attacks</a>, <a href="https://publications.waset.org/abstracts/search?q=MS-DoS-SIP" title=" MS-DoS-SIP"> MS-DoS-SIP</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20model" title=" security model"> security model</a>, <a href="https://publications.waset.org/abstracts/search?q=VoIP-SIP%20vulnerabilities" title=" VoIP-SIP vulnerabilities"> VoIP-SIP vulnerabilities</a> </p> <a href="https://publications.waset.org/abstracts/85955/towards-a-security-model-against-denial-of-service-attacks-for-sip-traffic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85955.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">203</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> Online Formative Assessment Challenges Experienced by Grade 10 Physical Sciences Teachers during Remote Teaching and Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Celeste%20Labuschagne">Celeste Labuschagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Sam%20Ramaila"> Sam Ramaila</a>, <a href="https://publications.waset.org/abstracts/search?q=Thasmai%20Dhurumraj"> Thasmai Dhurumraj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although formative assessment is acknowledged as crucial for teachers to gauge students’ understanding of subject content, applying formative assessment in an online context is more challenging than in a traditional Physical Sciences classroom. This study examines challenges experienced by Grade 10 Physical Sciences teachers when enacting online formative assessment. The empirical investigation adopted a generic qualitative design and involved three purposively selected Grade 10 Physical Sciences teachers from three different schools and quintiles within the Tshwane North District in South Africa. Data were collected through individual and focus group interviews. Technological, pedagogical, and content knowledge (TPACK) was utilised as a theoretical framework underpinning the study. The study identified a myriad of challenges experienced by Grade 10 Physical Sciences teachers when enacting online formative assessment. These challenges include the utilisation of Annual Teaching Plans, lack of technological knowledge, and internet connectivity. The Department of Basic Education faces the key imperative to provide continuous teacher professional development and concomitant online learning materials that can facilitate meaningful enactment of online formative assessment in various educational settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20formative%20assessment" title=" online formative assessment"> online formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20sciences" title=" physical sciences"> physical sciences</a>, <a href="https://publications.waset.org/abstracts/search?q=TPACK" title=" TPACK"> TPACK</a> </p> <a href="https://publications.waset.org/abstracts/175113/online-formative-assessment-challenges-experienced-by-grade-10-physical-sciences-teachers-during-remote-teaching-and-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175113.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">66</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> Waste from Drinking Water Treatment: The Feasibility for Application in Building Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Correa">Marco Correa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing reduction of the volumes of surface water sources supplying most municipalities, as well as the rising demand for treated water, combined with the disposal of effluents from washing of decanters and filters of water treatment plants generates a continuous search for correct environmentally solutions to these problems. The effluents generated by the water treatment industry need to be suitably processed for return to the environment or re-use. This article shows alternatives for sludge dehydration from the water treatment plants (WTP) and eventual disposal of sludge drained. Using the simple design methodology, it is presented a case study for drainage in tanks geotextile, full-scale, which involve five sledge drainage tanks from WTP of the city of Rio Verde. Aiming to the reutilization of drained water from the sledge and enabling its reuse both at the beginning of the treatment process at the WTP and in less noble services as for watering the gardens of the local town hall.

Due to threshold structures commonly occurring in CRR models, the associated mathematical optimization problems have the significant characteristic of being strongly non-differentiable. In order to face this enormous task, the resolution method proposed adopts a smoothing strategy using a special C∞ differentiable class function. The final estimation solution is obtained by solving a sequence of differentiable subproblems which gradually approach the original conceptual problem. The use of this technique, called Hyperbolic Smoothing Method (HSM), makes possible the application of the most powerful minimization algorithms, and also allows for the main difficulties presented by the original CRR problem to be overcome. A set of computational experiments is presented for the purpose of illustrating both the reliability and the efficiency of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rainfall-runoff%20models" title="rainfall-runoff models">rainfall-runoff models</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20calibration" title=" automatic calibration"> automatic calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20smoothing%20method" title=" hyperbolic smoothing method"> hyperbolic smoothing method</a> </p> <a href="https://publications.waset.org/abstracts/123935/the-hyperbolic-smoothing-approach-for-automatic-calibration-of-rainfall-runoff-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123935.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">149</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> Experimental Approach for Determining Hemi-Anechoic Characteristics of Engineering Acoustical Test Chambers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Montoya-Ospina">Santiago Montoya-Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20E.%20Jim%C3%A9nez-Mej%C3%ADa"> Raúl E.

As a result, it was observed that the welds in both processes have different characteristics in relation to the metallurgical properties and performance, but they present good weldability, satisfactory mechanical strength e developed mathematical models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flux%20Cored%20Arc%20Welding%20%28FCAW%29" title="Flux Cored Arc Welding (FCAW)">Flux Cored Arc Welding (FCAW)</a>, <a href="https://publications.waset.org/abstracts/search?q=Gas%20Metal%20Arc%20Welding%20%28GMAW%29" title=" Gas Metal Arc Welding (GMAW)"> Gas Metal Arc Welding (GMAW)</a>, <a href="https://publications.waset.org/abstracts/search?q=Design%20of%20Experiments%20%28DOE%29" title=" Design of Experiments (DOE)"> Design of Experiments (DOE)</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20models" title=" mathematical models"> mathematical models</a> </p> <a href="https://publications.waset.org/abstracts/29499/mathematical-models-for-gmaw-and-fcaw-welding-processes-for-structural-steels-used-in-the-oil-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29499.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">560</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> Dehydration of Residues from WTP for Application in Building Materials and Reuse of Water from the Waste Treatment: A Feasible Solution to Complete Treatment Systems </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Correa">Marco Correa</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Araujo"> Flavio Araujo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Scalize"> Paulo Scalize</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Albuquerque"> Antonio Albuquerque</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing reduction of the volumes of surface water sources which supply most municipalities, as well as the continued rise of demand for treated water, combined with the disposal of effluents from washing of decanters and filters of the water treatment plants, generates a continuous search for correct environmentally solutions to these problems. The effluents generated by the water treatment industry need to be suitably processed for return to the environment or re-use. This article shows an alternative for the dehydration of sludge from the water treatment plants (WTP) and eventual disposal of sludge drained. Using the simple design methodology, we present a case study for a drainage in tanks geotextile, full-scale, which involve five sludge drainage tanks from WTP of the Rio Verde City. Aiming to the reutilization the water drained from the sludge and enabling its reuse both at the beginning of the treatment process at the WTP and in less noble services as for watering the gardens of the local town hall. The sludge will be used to production of building materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=re-use" title="re-use">re-use</a>, <a href="https://publications.waset.org/abstracts/search?q=residue" title=" residue"> residue</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment%20plants" title=" water treatment plants"> water treatment plants</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge" title=" sludge"> sludge</a> </p> <a href="https://publications.waset.org/abstracts/22217/dehydration-of-residues-from-wtp-for-application-in-building-materials-and-reuse-of-water-from-the-waste-treatment-a-feasible-solution-to-complete-treatment-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22217.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">490</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> Beyond Learning Classrooms: An Undergraduate Experience at Instituto Politecnico Nacional Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Sandoval%20Lezama">Jorge Sandoval Lezama</a>, <a href="https://publications.waset.org/abstracts/search?q=Arturo%20Ivan%20Sandoval%20Rodriguez"> Arturo Ivan Sandoval Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Arturo%20Correa%20Arredondo"> Jose Arturo Correa Arredondo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work aims to share innovative educational experiences at IPN Mexico, that involve collaborative learning at institutional and global level through course competition and global collaboration projects.

The participation of IPN students in the 2015-2016 global competition (São Paolo, Brazil and Cincinnati, USA) Reconfigurable Shared-Use Mobility Systems allowed to apply pedagogical strategies of groups of collaboration and of learning based on projects where they shared activities, commitments and goals, demonstrating that students were motivated to develop / self-generate their knowledge with greater meaning and understanding. One of the most evident achievements is that the students are self-managed, so the most advanced students train the students who join the project with CAD, CAE, CAM tools. Likewise, the motivation achieved is evident since in 2014 there were 12 students involved in the project, and there are currently more than 70 students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaboration%20projects" title="collaboration projects">collaboration projects</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20competency" title=" global competency"> global competency</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20competition" title=" course competition"> course competition</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20learning" title=" active learning"> active learning</a> </p> <a href="https://publications.waset.org/abstracts/70480/beyond-learning-classrooms-an-undergraduate-experience-at-instituto-politecnico-nacional-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70480.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">53</span> Improvement on the Specific Activities of Immobilized Enzymes by Poly(Ethylene Oxide) Surface Modification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaohua%20Li">Shaohua Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Aihua%20Zhang"> Aihua Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelly%20Zatopek"> Kelly Zatopek</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Parvez"> Saba Parvez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20F.%20Gardner"> Andrew F.

Nevertheless, immobilized enzymes generally suffer from reduced activities compared to their soluble counterparts. One major factor leading to activity loss is the intrinsic hydrophobic property of the supporting material surface, which could result in the conformational change/confinement of enzymes. We report a strategy of utilizing flexible poly (ethylene oxide) (PEO) moieties as to improve the surface hydrophilicity of solid supports used for enzyme immobilization. DNA modifying enzymes were covalently conjugated to PEO-coated magnetic-beads. Kinetics studies proved that the activities of the covalently-immobilized DNA modifying enzymes were greatly enhanced by the PEO modification on the bead surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immobilized%20enzymes" title="immobilized enzymes">immobilized enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=biocatalysis" title=" biocatalysis"> biocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28ethylene%20oxide%29" title=" poly(ethylene oxide)"> poly(ethylene oxide)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20modification" title=" surface modification"> surface modification</a> </p> <a href="https://publications.waset.org/abstracts/79716/improvement-on-the-specific-activities-of-immobilized-enzymes-by-polyethylene-oxide-surface-modification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79716.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">308</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> Durability of Reinforced Concrete Structure on Very High Aggressive Environment: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karla%20Peitl%20Miller">Karla Peitl Miller</a>, <a href="https://publications.waset.org/abstracts/search?q=Leomar%20Bravin%20Porto"> Leomar Bravin Porto</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaitto%20Correa%20Fraga"> Kaitto Correa Fraga</a>, <a href="https://publications.waset.org/abstracts/search?q=Nataniele%20Eler%20Mendes"> Nataniele Eler Mendes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the evaluation and study of a real reinforced concrete structure of a fertilizer storage building, constructed on a Vale’s Port at Brazil, which has been recently under refurbishment.

It should be present in every stage of research in a systemic way. However, this process is not always efficient and effective. Reports of researchers focused on agribusiness point to difficulties in communicating with farmers that negatively impact on research results and may cause distortions and even quite significant inconsistencies. This research aims at identifying the main noise and barriers in communication between agribusiness researchers and farmers. It discusses the possibility of creating a specific strategy to correct or minimize such failures. The main research question: what features of the communication process will be decisive for the communication between agribusiness researcher and farmer occur with greater efficiency? It is expected that the research will result in processes that may correct or minimize such problems, promoting dialogues more efficient knowledge. The research will adopt a qualitative approach, using action research as a form of investigative action for social and educational nature, aiming at promoting understanding and interaction between researchers and members of the investigated situations. To collect and analyze data to document analysis will be used; questionnaires and interviews and content analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agribusiness%20farmers" title="agribusiness farmers">agribusiness farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=researchers" title=" researchers"> researchers</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20communication" title=" science communication"> science communication</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a> </p> <a href="https://publications.waset.org/abstracts/27646/science-communication-a-possible-dialogue-between-researchers-and-agribusiness-farmers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27646.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">276</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> Creating Bridges: The Importance of Intergenerational Experiences in the Educational Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Eiguren-Munitis">A.

This situation gives rise to a greater lack of social protection of the groups in vulnerable situations, such as the elderly and children. There is a growing need to search for shared spaces where different generations manage to break negative stereotypes and interact with each other. The school environment provides a favourable context in which the approach of different generations can be worked on. The intergenerational experiences that take place within the school context help to introduce the educational ideology for a lifetime. This induces bilateral learning, which encourages citizen participation. For this reason, the general objective of this research is to deepen the impact that intergenerational experiences have on participating students. The research is carried out based on mixed methods. The qualitative and quantitative evaluation included pre-test and post-test questionnaires (n=148) and group interviews (n=43). The results indicate that the intergenerational experiences influence different levels, on the one hand, help to promote school motivation and on the other hand, help to reduce negative stereotypes towards older people thus contributing to greater social cohesion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intergenerational%20learning" title="intergenerational learning">intergenerational learning</a>, <a href="https://publications.waset.org/abstracts/search?q=school" title=" school"> school</a>, <a href="https://publications.waset.org/abstracts/search?q=stereotypes" title=" stereotypes"> stereotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20cohesion" title=" social cohesion"> social cohesion</a> </p> <a href="https://publications.waset.org/abstracts/132952/creating-bridges-the-importance-of-intergenerational-experiences-in-the-educational-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132952.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Development of Filling Material in 3D Printer with the Aid of Computer Software for Supported with Natural Zeolite for the Removal of Nitrogen and Phosphorus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Fernando%20Cusioli">Luís Fernando Cusioli</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Nishi"> Leticia Nishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Bairros"> Lucas Bairros</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Xavier%20Jorge"> Gabriel Xavier Jorge</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandro%20Rog%C3%A9rio%20Lautenschalager"> Sandro Rogério Lautenschalager</a>, <a href="https://publications.waset.org/abstracts/search?q=Celso%20Varutu%20Nakamura"> Celso Varutu Nakamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Ros%C3%A2ngela%20Bergamasco"> Rosângela Bergamasco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Focusing on the elimination of nitrogen and phosphorus from sewage, the study proposes to face the challenges of eutrophication and to optimize the effectiveness of sewage treatment through biofilms and filling produced by a 3D printer, seeking to identify the most effective Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS). The study also proposes to evaluate the nitrification process in a Submerged Aerated Biological Filter (FBAS) on a pilot plant scale, quantifying the removal of nitrogen and phosphorus. The experiment will consist of two distinct phases, namely, a bench stage and the implementation of a pilot plant. During the bench stage, samples will be collected at five points to characterize the microbiota. Samples will be collected, and the microbiota will be investigated using Fluorescence In Situ Hybridization (FISH), deepening the understanding of the performance of biofilms in the face of multiple variables.

The cultivar under storage is Pant Sujata. CFB box packing resulted in minimum 21 % PLW during 2010-11 during its 28-35 days storage under ambient temperature. CFB box and Gunny bag retains maximum total sugar (17.3-17.4 °B) after 28 days storage. Bael pulp of cultivar Pant Sujata can be stored up to 2 months at 4 °C with good quality condition. Treatments were highly significant in the characters such as T.S.S., acidity, reducing sugar and total sugar. Storage conditions and treatments interaction were insignificant in all characters except acidity. The maximum T.S.S. of 21.87 °B has been found in sample treated with 800 ppm benzoic acid when kept for two months at 4 °C temperature. This treatment also resulted in retaining the maximum reducing sugar (8.09 %) and total sugar content (9.52 %) at same storage condition than other treatments. From the present experiments, it is concluded that CFB box packing and pulp storage with 800 ppm benzoic acid at 4 °C are important to extent the availability of bael for two months. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bael" title="bael">bael</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits" title=" fruits"> fruits</a>, <a href="https://publications.waset.org/abstracts/search?q=pulp" title=" pulp"> pulp</a>, <a href="https://publications.waset.org/abstracts/search?q=benzoic%20acid" title=" benzoic acid"> benzoic acid</a> </p> <a href="https://publications.waset.org/abstracts/42619/storage-study-of-bael-aegle-marmelos-correa-fruit-and-pulp-of-cv-pant-sujata" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42619.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">247</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">47</span> Overall Function and Symptom Impact of Self-Applied Myofascial Release in Adult Patients With Fibromyalgia.

Management of symptoms include medications, physical treatments and mindfulness therapies. Myofascial Release is a modality that has been successfully applied in var-ious musculoskeletal conditions. However, to the author’s best knowledge, it is not yet recog-nized as a self-management therapy option in Fibromyalgia. In this study, we investigated whether Self-applied Myofascial Release (SMR) is associated with overall improved function and symptoms in Fibromyalgia. Methods: Eligible adult patients with a confirmed diagnosis of Fibromyalgia at Women’s College Hospital were recruited to SMR. Sessions ran for 1 hour once a week for 7 weeks, led by the same two Physiotherapists knowledgeable in this physical treat-ment modality. The main outcome measure was an overall impact score for function and symp-toms based on the validated assessment tool for Fibromyalgia, the Revised Fibromyalgia Impact Questionnaire (FIQR), measured pre and post-intervention. Both descriptive and analytical methods were applied and reported. Results: We analyzed results using a paired t-test to deter-mine if there was a statistically significant difference in mean FIQR scores between initial (pre-intervention) and final (post-intervention) scores. A clinically significant difference in FIQR was defined as a reduction in score by 10 or more points. Conclusions: Our pilot study showed that SMR appeared to be a safe and effective intervention for our Fibromyalgia participants and the overall impact on function and symptoms occurred in only 7 weeks. Further studies with larger sample sizes comparing SMR to other physical treatment modalities (such as stretching) in an RCT are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibromyalgia" title="fibromyalgia">fibromyalgia</a>, <a href="https://publications.waset.org/abstracts/search?q=myofascial%20release" title=" myofascial release"> myofascial release</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title=" physical therapy"> physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=FIQR" title=" FIQR"> FIQR</a> </p> <a href="https://publications.waset.org/abstracts/155342/overall-function-and-symptom-impact-of-self-applied-myofascial-release-in-adult-patients-with-fibromyalgia-a-seven-week-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155342.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">76</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> Analysis of Gas Transport and Sorption Processes in Coal under Confining Pressure Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Pajdak">Anna Pajdak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20%20Kudasik"> Mateusz Kudasik</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20%20Skoczylas"> Norbert Skoczylas</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Teixeira%20Palla%20Braga"> Leticia Teixeira Palla Braga </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A substantial majority of gas transport and sorption researches into coal are carried out on samples that are free of stress. In natural conditions, coal occurs at considerable depths, which often exceed 1000 meters. In such conditions, coal is subjected to geostatic pressure. Thus, in natural conditions, the sorption capacity of coal subjected to geostatic pressure can differ considerably from the sorption capacity of coal, determined in laboratory conditions, which is free of stress. The work presents the results of filtration and sorption tests of gases in coal under confining pressure conditions. The tests were carried out on the author's device, which ensures: confining pressure regulation in the range of 0-30 MPa, isobaric gas pressure conditions, and registration of changes in sample volume during its gas saturation. Based on the conducted research it was found, among others, that the sorption capacity of coal relative to CO₂ was reduced by about 15% as a result of the change in the confining pressure from 1.5 MPa to 30 MPa exerted on the sample. The same change in sample load caused a significant, more than tenfold reduction in carbon permeability to CO₂. The results confirmed that a load of coal corresponding to a hydrostatic pressure of 1000 meters underground reduces its permeability and sorption properties. These results are so important that the effect of load on the sorption properties of coal should be taken into account in laboratory studies on the applicability of CO₂ Enhanced Coal Bed Methane Recovery (CO₂-ECBM) technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal" title="coal">coal</a>, <a href="https://publications.waset.org/abstracts/search?q=confining%20pressure" title=" confining pressure"> confining pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20transport" title=" gas transport"> gas transport</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption" title=" sorption"> sorption</a> </p> <a href="https://publications.waset.org/abstracts/124125/analysis-of-gas-transport-and-sorption-processes-in-coal-under-confining-pressure-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124125.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">121</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> The Influence of Audio on Perceived Quality of Segmentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvio%20Ricardo%20Rodrigues%20Sanches">Silvio Ricardo Rodrigues Sanches</a>, <a href="https://publications.waset.org/abstracts/search?q=Bianca%20Cogo%20Barbosa"> Bianca Cogo Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Regina%20Brum"> Beatriz Regina Brum</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9ber%20Gimenez%20Corr%C3%AAa"> Cléber Gimenez Corrêa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To evaluate the quality of a segmentation algorithm, the authors use subjective or objective metrics. Although subjective metrics are more accurate than objective ones, objective metrics do not require user feedback to test an algorithm. Objective metrics require subjective experiments only during their development. Subjective experiments typically display to users some videos (generated from frames with segmentation errors) that simulate the environment of an application domain. This user feedback is crucial information for metric definition. In the subjective experiments applied to develop some state-of-the-art metrics used to test segmentation algorithms, the videos displayed during the experiments did not contain audio. Audio is an essential component in applications such as videoconference and augmented reality. If the audio influences the user’s perception, using only videos without audio in subjective experiments can compromise the efficiency of an objective metric generated using data from these experiments. This work aims to identify if the audio influences the user’s perception of segmentation quality in background substitution applications with audio. The proposed approach used a subjective method based on formal video quality assessment methods. The results showed that audio influences the quality of segmentation perceived by a user. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=background%20substitution" title="background substitution">background substitution</a>, <a href="https://publications.waset.org/abstracts/search?q=influence%20of%20audio" title=" influence of audio"> influence of audio</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation%20evaluation" title=" segmentation evaluation"> segmentation evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation%20quality" title=" segmentation quality"> segmentation quality</a> </p> <a href="https://publications.waset.org/abstracts/148456/the-influence-of-audio-on-perceived-quality-of-segmentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148456.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">117</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> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals. Objective: To determine the prevalence and characteristics of consumption of nutraceuticals in undergraduate students. Methodology: Cross-sectional study. It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">577</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Impact of Neuropsychological Intervention in Mild Cognitive Impairment: A Controlled, Randomized and Blind Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20de%20Oliveira%20Ferreira%20Leite">Amanda de Oliveira Ferreira Leite</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Luiza%20del%20Pino%20Ferreira"> Ana Luiza del Pino Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruna%20Garcez%20Correa"> Bruna Garcez Correa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jana%C3%ADne%20de%20Souza%20Mello"> Janaíne de Souza Mello</a>, <a href="https://publications.waset.org/abstracts/search?q=Marla%20Manquevich"> Marla Manquevich</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirna%20Wetters%20Portuguez"> Mirna Wetters Portuguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: We sought to investigate a neuropsychological intervention focused on improving cognition, psychological aspects, and quality of life of elderly people with mild cognitive impairment. Method: A controlled and randomized study, blind to the evaluator, was executed. We evaluated 78 elderly people, divided into the neuropsychological and control groups, through a semi-structured interview, Addenbrooke’s Cognitive Examination, Katz Index, Lawton and Brody Scale, Geriatric Depression Scale, Beck Anxiety Inventory, Personal Development Scale, WHOQOL-bref and WHOQOL--old. Results: After the intervention, the neuropsychological group showed improvement in the cognitive subtests and in the total score, reduction in the frequency of symptoms associated with anxiety and depression, better psychological well-being, and quality of life. The research highlights useful intervention strategies for improving the general condition of these patients and rehabilitating damaged areas. Conclusion: We concluded that there is a relationship between neuropsychological intervention and improvement in cognitive and psychological performance, as well as in the quality of life in elderly people with mild cognitive impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging" title="aging">aging</a>, <a
