In this scenario, we have significant changes in plant development, and consequently, in agricultural systems. This study aims to evaluate the interaction between culture (<em>Glycine max</em>) and weed (<em>Amaranthus viridis</em> and <em>Euphorbia heterophylla</em>) in two conditions of CO<sub>2</sub>, 400 and 800 ppm. The results showed that the coexistence of culture with both weed species resulted in a mutual loss, with decrease in dry mass productivity of culture + weeds, in both conditions of CO<sub>2</sub>. However, when the culture is grown in association with <em>E. heterophylla</em>, total dry mass of culture + weed was smaller at 800 ppm. Soybean was more aggressive in comparison to the <em>A. viridis</em> in both the concentrations of CO<sub>2</sub>, but not in relation to the <em>E. heterophylla</em>. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plants%20interaction" title="plants interaction">plants interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=increase%20of%20%5BCO%E2%82%82%5D" title=" increase of [CO₂]"> increase of [CO₂]</a>, <a href="https://publications.waset.org/abstracts/search?q=plants%20of%20metabolismo%20C3" title=" plants of metabolismo C3"> plants of metabolismo C3</a>, <a href="https://publications.waset.org/abstracts/search?q=glycine%20max" title=" glycine max"> glycine max</a> </p> <a href="https://publications.waset.org/abstracts/71620/increase-of-atmosphere-co2-concentration-and-its-effects-on-cultureweed-interaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71620.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">399</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">237</span> Pretreatment of Cattail (Typha domingensis) Fibers to Obtain Cellulose Nanocrystals </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marivane%20Turim%20Koschevic">Marivane Turim Koschevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Maycon%20dos%20Santos"> Maycon dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Lima%20Bertuci"> Marcello Lima Bertuci</a>, <a href="https://publications.waset.org/abstracts/search?q=Farayde%20Matta%20Fakhouri"> Farayde Matta Fakhouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Maria%20Martelli"> Silvia Maria Martelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural fibers are rich raw materials in cellulose and abundant in the world, its use for the cellulose nanocrystals extraction is promising as an example cited is the cattail, macrophyte native weed in South America.

The augmented reality is a new technology that stills being developed in terms of software and hardware. This technology consists of an image capture device, a device for data processing and an image visualization equipment to visualize collected and processed images. It is characterized by being a technology that merges the reality with the virtual environment, so there is an instantaneous interaction between the two environments. The present work intends to demonstrate that the use of the augmented reality will contribute to improve some tools and methods used in Lean manufacturing philosophy. Through several examples of application in industry it will be demonstrated that the technological impact of the augmented reality on the Lean Manufacturing philosophy contribute to added value improvements. <p class="card-text"><strong>Keywords:</strong> <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=augmented%20reality" title=" augmented reality"> augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20studies" title=" case studies"> case studies</a>, <a href="https://publications.waset.org/abstracts/search?q=value" title=" value "> value </a> </p> <a href="https://publications.waset.org/abstracts/29014/augmented-reality-as-enhancer-of-the-lean-philosophy-an-exploratory-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29014.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">624</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">235</span> Economic Decision Making under Cognitive Load: The Role of Numeracy and Financial Literacy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V%C3%A2nia%20Costa">Vânia Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20De%20S%C3%A1%20Teixeira"> Nuno De Sá Teixeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20C.%20Santos"> Ana C.

However, financial decisions are often made under sub-optimal circumstances, including cognitive overload. The present study aims to clarify how financial literacy and numeracy, taken as relevant expert knowledge for financial decision-making, modulate possible effects of cognitive load. Participants were required to perform a choice between a sure loss or a gambling pertaining a financial investment, either with or without a competing memory task. Two experiments were conducted varying only the content of the competing task. In the first, the financial choice task was made while maintaining on working memory a list of five random letters. In the second, cognitive load was based upon the retention of six random digits. In both experiments, one of the items in the list had to be recalled given its serial position. Outcomes of the first experiment revealed no significant main effect or interactions involving cognitive load manipulation and numeracy and financial literacy skills, strongly suggesting that retaining a list of random letters did not interfere with the cognitive abilities required for financial decision making. Conversely, and in the second experiment, a significant interaction between the competing mnesic task and level of financial literacy (but not numeracy) was found for the frequency of choice of a gambling option. Overall, and in the control condition, both participants with high financial literacy and high numeracy were more prone to choose the gambling option. However, and when under cognitive load, participants with high financial literacy were as likely as their illiterate counterparts to choose the gambling option. This outcome is interpreted as evidence that financial literacy prevents intuitive risk-aversion reasoning only under highly favourable conditions, as is the case when no other task is competing for cognitive resources. In contrast, participants with higher levels of numeracy were consistently more prone to choose the gambling option in both experimental conditions. These results are discussed in the light of the opposition between classical dual-process theories and fuzzy-trace theories for intuitive decision making, suggesting that while some instances of expertise (as numeracy) are prone to support easily accessible gist representations, other expert skills (as financial literacy) depend upon deliberative processes. It is furthermore suggested that this dissociation between types of expert knowledge might depend on the degree to which they are generalizable across disparate settings. Finally, applied implications of the present study are discussed with a focus on how it informs financial regulators and the importance and limits of promoting financial literacy and general numeracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title="decision making">decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20load" title=" cognitive load"> cognitive load</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20literacy" title=" financial literacy"> financial literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=numeracy" title=" numeracy"> numeracy</a> </p> <a href="https://publications.waset.org/abstracts/97270/economic-decision-making-under-cognitive-load-the-role-of-numeracy-and-financial-literacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97270.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">182</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">234</span> The Attitudes of Senior High School Students Toward Work Immersion Programs of Nazareth School of National University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kim%20Katherine%20Castillo">Kim Katherine Castillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20John%20Datubatang"> Nelson John Datubatang</a>, <a href="https://publications.waset.org/abstracts/search?q=Terrence%20Phillip%20Dy"> Terrence Phillip Dy</a>, <a href="https://publications.waset.org/abstracts/search?q=Norelie%20Hampac"> Norelie Hampac</a>, <a href="https://publications.waset.org/abstracts/search?q=Reichen%20Crismark%20Martinez"> Reichen Crismark Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Faith%20Pantinople"> Nina Faith Pantinople</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Dante%20Santos%20II"> Jose Dante Santos II</a>, <a href="https://publications.waset.org/abstracts/search?q=Marchel%20Ann%20Santos"> Marchel Ann Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophia%20Abigail%20Santiago"> Sophia Abigail Santiago</a>, <a href="https://publications.waset.org/abstracts/search?q=Zyrill%20Xsar%20San%20Juan"> Zyrill Xsar San Juan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aira%20Mae%20Tagao"> Aira Mae Tagao</a>, <a href="https://publications.waset.org/abstracts/search?q=Crystal%20Kylla%20Viagedor"> Crystal Kylla Viagedor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Work Immersion Program was implemented to help students gain abundant work-related experiences while on-site; additionally, the program aims to help students improve their competencies and interpersonal skills as they are given the option to join the workforce if they ever choose to do so after senior high school. The work immersion experience posed diverse challenges for students, spanning personal, financial, engagement, environmental, and equipment-related domains. These included the need for assistance in time management, transportation expenses, and procurement of materials. Furthermore, students faced difficulties in independent task completion and encountered suboptimal work environments. Addressing these multifaceted obstacles is crucial to optimize the educational outcomes of work immersion programs. In addition to the challenges, several other issues have been identified, including the absence of standardized work immersion programs across schools and industries, the challenges in securing appropriate work immersion placements, the necessity for enhanced monitoring and evaluation of program effectiveness, and the limited availability of field programs aligned with students' chosen courses. Furthermore, there is a lack of comprehensive information regarding the attitudes of Senior High School students toward work immersion programs within their respective schools. This study aims to investigate the attitudes of senior high school students at Nazareth School of National University towards work immersion programs, with a focus on identifying factors that influence their perception and participation, including collegiality and expectations. By exploring the students' attitudes, the research endeavors to enhance the school's work immersion programs and contribute to the overall educational experience of the students. This study addresses challenges related to work immersion programs, focusing on six subtopics: Work Immersion, Work Immersion in the Philippines, Students' Attitudes, Factors Affecting Students' Attitudes, Effectiveness of Work Immersion for Senior High School Students, and Students' Perception and Willingness to Participate. Using a descriptive research design, the study examines the attitudes of senior high school students at Nazareth School of National University in Manila. Data was collected from 100 students, representing different academic strands, through a 35-item researcher-made survey. Descriptive statistics, including measures of central tendency and variability, will be used to analyze the data using JASP, providing valuable insights into the students' attitudes toward work immersion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitudes" title="attitudes">attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20outcomes" title=" educational outcomes"> educational outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20immersion%20programs" title=" work immersion programs"> work immersion programs</a> </p> <a href="https://publications.waset.org/abstracts/167521/the-attitudes-of-senior-high-school-students-toward-work-immersion-programs-of-nazareth-school-of-national-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167521.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">95</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">233</span> A3 Strategy Deployment: A Case Study Applied to a City Government Department for Healthcare in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Bonato">Samuel Bonato</a>, <a href="https://publications.waset.org/abstracts/search?q=Cineia%20Santos"> Cineia Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberta%20Leite"> Roberta Leite</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20Ten%20Caten"> Carla Ten Caten</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to apply the A3 strategy deployment in a local department for healthcare. As a literature review, it was evaluated articles related to the period 2009 - 2018, considering the key-words A3, healthcare, public services and strategy deployment. The methodology used was action research, involving all the actors inside the secretary, beginning with the top management and deploying it through meetings and evaluation conferences with the participation of all secretary coordination. As main results, it is possible to highlight the development of 8 A3, one as the "mother A3" and 7 as "son A3", each one related to each coordination. In each A3, past results, new goals, new projects to achieve these goals and control deadlines were defined and implemented to a management strategy. In addition to this result, this paper is planning to present the use of this A3 during 6 months in 2019. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A3%20Strategy" title="A3 Strategy">A3 Strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy%20deployment" title=" strategy deployment"> strategy deployment</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=Public%20services" title=" Public services"> Public services</a> </p> <a href="https://publications.waset.org/abstracts/105041/a3-strategy-deployment-a-case-study-applied-to-a-city-government-department-for-healthcare-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105041.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">232</span> Development of the Family Capacity of Management of Patients with Autism Spectrum Disorder Diagnosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcio%20Emilio%20Dos%20Santos">Marcio Emilio Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelly%20C.%20F.%20Dos%20Santos"> Kelly C.

The cognitive and emotional requirement needed to fulfill this caregiving role exceeds the regular cultural process that adults receive in their process of preparation for conjugal and parental life. Therefore, in many cases, caregivers present a high level of overload, poor capacity to organize and mediate the development process of the child or patient about their care. Aims: Improvement in the cognitive and emotional capacities related to the caregiver function, allowing the reduction of the overload, the feeling of incompetence and the characteristic level of stress, developing a more organized conduct and decision making more oriented towards the objectives and procedural gains necessary for the integral development of the patient with diagnosis of ASD. Method: The study was performed with 20 relatives, randomly selected from a total of 140 patients attended. The family members were submitted to the Wechsler Adult Intelligence Scale III intelligence test and the Family assessment Management Measure (FaMM) questionnaire as a previous evaluation. Therapeutic activity in a small group of family members or caregivers, with weekly frequency, with a minimum workload of two hours, using the Feuerstein Instrumental Enrichment Cognitive Development Program - Feuerstein Instrumental Enrichment for ten months. Reapplication of the previous tests to verify the gains obtained. Results and Discussion: There is a change in the level of caregiver overload, improvement in the results of the Family assessment Management Measure and highlight to the increase of performance in the cognitive aspects related to problem solving, planned behavior and management of behavioral crises. These results lead to the discussion of the need to invest in the integrated care of patients and their caregivers, mainly by enabling cognitively to deal with the complexity of Autism. This goes beyond the simple therapeutic orientation about adjustments in family and school routines. The study showed that when the caregiver improves his/her capacity of management, the results of the treatment are potentiated and there is a reduction of the level of the caregiver's overload. Importantly, the study was performed for only ten months and the number of family members attended in the study (n = 20) needs to be expanded to have statistical strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caregiver%20overload" title="caregiver overload">caregiver overload</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20development%20program%20ASD%20caregivers" title=" cognitive development program ASD caregivers"> cognitive development program ASD caregivers</a>, <a href="https://publications.waset.org/abstracts/search?q=feuerstein%20instrumental%20enrichment" title=" feuerstein instrumental enrichment"> feuerstein instrumental enrichment</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20assessment%20management%20measure" title=" family assessment management measure"> family assessment management measure</a> </p> <a href="https://publications.waset.org/abstracts/107269/development-of-the-family-capacity-of-management-of-patients-with-autism-spectrum-disorder-diagnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107269.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">128</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">231</span> Cost of Outpatient Procedures for Ostomized Patients Treated in the Public Health Network in Brazil and Its Impact on the Budget of the Unified Health System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karina%20Guimaraes">Karina Guimaraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lilian%20Santos"> Lilian Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has the purpose of planning and instituting monitoring actions as a way of knowing the scenario of assistance to the patient with stoma, treated in the public health network in Brazil, from January to November of the year 2016, from the elaboration of a technical document containing the survey of the number of procedures offered and the value of the ostomy services, accredited in the Unified Health System-SUS.

A detailed analysis of the emission spectra revealed that the EuTTA phase still remains in the hybrid phase. Sparkle Model calculations of the EuTTA ground state geometry have been performed and satisfactorily compared to the X-ray structure. The observed weaker crystal field strength of the phase generated by the incorporation is promptly interpreted through the existing EXAFS results of the EuTTA-hyb structure. Satisfactory predictions of the CFP, of the 7F1 level splitting and of the Ωλ in all cases were obtained by using the charge factors and polarizabilities as degrees of freedom of non-parametric models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crystal%20field%20parameters" title="crystal field parameters">crystal field parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=europium%20complexes" title=" europium complexes"> europium complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=Judd-Ofelt%20intensity%20parameters" title=" Judd-Ofelt intensity parameters"> Judd-Ofelt intensity parameters</a> </p> <a href="https://publications.waset.org/abstracts/13357/spectroscopic-study-of-a-eu-complex-containing-hybrid-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13357.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">408</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">227</span> A Bathtub Curve from Nonparametric Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20C.%20Guardia">Eduardo C.

The model is a mixture of the three known phases of a component life, the decreasing failure rate (DFR), the constant failure rate (CFR) and the increasing failure rate (IFR) represented by three parametric Weibull models. The parameters are obtained from a simultaneous fitting process of the model to the Kernel nonparametric hazard rate curve. From the Weibull parameters and failure rate curves the useful lifetime and the characteristic lifetime were defined. To demonstrate the model the historic time-to-failure of distribution transformers were used as an example. The resulted “Bathtub curve” shows the failure rate for the equipment lifetime which can be applied in economic and replacement decision models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bathtub%20curve" title="bathtub curve">bathtub curve</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20analysis" title=" failure analysis"> failure analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lifetime%20estimation" title=" lifetime estimation"> lifetime estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20estimation" title=" parameter estimation"> parameter estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=Weibull%20distribution" title=" Weibull distribution"> Weibull distribution</a> </p> <a href="https://publications.waset.org/abstracts/10780/a-bathtub-curve-from-nonparametric-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10780.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">445</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">226</span> Relationship and Comorbidity Between Down Syndrome and Autism Spectrum Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javiera%20Espinosa">Javiera Espinosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20L%C3%B3pez"> Patricia López</a>, <a href="https://publications.waset.org/abstracts/search?q=Noelia%20Santos"> Noelia Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Loro"> Nadia Loro</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Moraleda"> Esther Moraleda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been a notable increase in the number of investigations that establish that Down Syndrome and Autism Spectrum Disorder are diagnoses that can coexist together. However, there are also many studies that consider that both diagnoses present neuropsychological, linguistic and adaptive characteristics with a totally different profile. The objective of this research is to question whether there really can be a profile that encompasses both disorders or if they can be incompatible with each other. To this end, a review of the scientific literature of recent years has been carried out. The results indicate that the two lines collect opposite approaches. On the one hand, there is research that supports the increase in comorbidity between Down Syndrome and Autism Spectrum Disorder, and on the other hand, many investigations show a totally different general development profile between the two. The discussion focuses on discussing both lines of work and on proposing future lines of research in this regard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disability" title="disability">disability</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=speech" title=" speech"> speech</a>, <a href="https://publications.waset.org/abstracts/search?q=down%20syndrome" title=" down syndrome"> down syndrome</a> </p> <a href="https://publications.waset.org/abstracts/179107/relationship-and-comorbidity-between-down-syndrome-and-autism-spectrum-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179107.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">73</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">225</span> Cerium Salt Effect in 70s Bioactive Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20N.%20Santos">Alessandra N.

In the present study, we evaluated the effects of early maternal separation on risky choice in rats. One group of male and female Wistar rats was exposed to an early maternal separation protocol while a control group was left undisturbed. Then both groups were exposed to a series of behavioral tests, including a test of risky choice, where one alternative offered a constant reward while the other offered a variable reward. There was a difference between groups when they chose between a variable and a constant reward delay, but no other difference was significant. These results suggest that early maternal separation may be related to a greater preference for shorter delays, which is characteristic of more impulsive choices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20maternal%20separation" title="early maternal separation">early maternal separation</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsivity" title=" impulsivity"> impulsivity</a>, <a href="https://publications.waset.org/abstracts/search?q=risky%20choice" title=" risky choice"> risky choice</a>, <a href="https://publications.waset.org/abstracts/search?q=variability" title=" variability"> variability</a> </p> <a href="https://publications.waset.org/abstracts/104561/the-effects-of-early-maternal-separation-on-risky-choice-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104561.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">256</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">223</span> Study of Adsorption Isotherm Models on Rare Earth Elements Biosorption for Separation Purposes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nice%20Vasconcelos%20Coimbra">Nice Vasconcelos Coimbra</a>, <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1bio%20dos%20Santos%20Gon%C3%A7alves"> Fábio dos Santos Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Marisa%20Nascimento"> Marisa Nascimento</a>, <a href="https://publications.waset.org/abstracts/search?q=Ellen%20Cristine%20Giese"> Ellen Cristine Giese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of chemical routes for the recovery and separation of rare earth elements (REE) is seen as a priority and strategic action by several countries demanding these elements. Among the possibilities of alternative routes, the biosorption process has been evaluated in our laboratory. In this theme, the present work attempts to assess and fit the solution equilibrium data in Langmuir, Freundlich and DKR isothermal models, based on the biosorption results of the lanthanum and samarium elements by <em>Bacillus subtilis</em> immobilized on calcium alginate gel. It was observed that the preference of adsorption of REE by the immobilized biomass followed the order Sm (III)> La (III). It can be concluded that among the studied isotherms models, the Langmuir model presented better mathematical results than the Freundlich and DKR models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rare%20earth%20elements" title="rare earth elements">rare earth elements</a>, <a href="https://publications.waset.org/abstracts/search?q=biosorption" title=" biosorption"> biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20subtilis" title=" Bacillus subtilis"> Bacillus subtilis</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherm%20models" title=" adsorption isotherm models"> adsorption isotherm models</a> </p> <a href="https://publications.waset.org/abstracts/95469/study-of-adsorption-isotherm-models-on-rare-earth-elements-biosorption-for-separation-purposes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95469.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">160</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">222</span> The Labor Participation–Fertility Trade-off: The Case of the Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daphne%20Ashley%20Sze">Daphne Ashley Sze</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenneth%20Santos"> Kenneth Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariane%20Gabrielle%20Lim"> Ariane Gabrielle Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As women are now given more freedom and choice to pursue employment, the world’s over-all fertility has been decreasing mainly due to the shift in time allocation between working and child rearing.

One of the strategies proposed to increase recovery is based on altering the wettability of oil reservoir rocks. Approximately 60% of world crude oil reservoirs have sandstone-type host rocks; for that, it is very important to develop efficient methodologies to alter the wettability of these rocks. In this study, the alteration of the wettability of a sandstone rock due to graphene oxide (GO) adsorption was evaluated. The effect of GO concentration, salinity, Ca2+ ions, and pH on interfacial tension and contact angle was determined. The results show that GO adsorption induces significant changes in rock wettability. For high GO concentrations and low salinity, pH proved to be a determining factor in the alteration of wettability. Under certain conditions, surface wettability changes from highly oleophilic (144,8°) to intermediate oil wettability (91,2°). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery" title="enhanced oil recovery">enhanced oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20tension" title=" interfacial tension"> interfacial tension</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title=" nanofluid"> nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=wettability" title=" wettability"> wettability</a> </p> <a href="https://publications.waset.org/abstracts/158084/wettability-alter-of-a-sandstone-rock-by-graphene-oxide-adsorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158084.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">106</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">220</span> The Labor Participation-Fertility Trade-Off: Exploring Fecundity and Its Consequences to Women's Employment in the Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariane%20C.%20Lim">Ariane C.

The objective of this research is to question whether there really can be a profile that encompasses both disorders or if they can be incompatible with each other. To this end, a review of the scientific literature of recent years has been carried out. The results indicate that the two lines collect opposite approaches. On the one hand, there is research that supports the increase in comorbidity between Down Syndrome and Autism Spectrum Disorder and, on the other hand, shows a totally different general development profile between the two.

Thus, it starts with a theoretical framework on the emergence of this topic in the European Innovation Policy (Section 2), then continues with the identification and systematization of the main mechanisms for its effective adoption, both on the demand and supply side of the market (Section 3), as well as to expose and describe methods and tools for positioning innovation at the heart of public entities. The innovative projects best distinguished by the European Commission for their good practices in innovation procurement are identified, and the main methodology for the development and management of innovation procurement – Forward Commitment Procurement (FCP) – is applied to them in a pioneering way (Section 4). The relevance of innovation in public procurement is systematized and reflected upon in Section 5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation%20procurement" title="innovation procurement">innovation procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20policy" title=" innovation policy"> innovation policy</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=pubic%20procurement" title=" pubic procurement"> pubic procurement</a> </p> <a href="https://publications.waset.org/abstracts/162173/mechanisms-for-strategic-adoption-of-innovation-procurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162173.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">215</span> Procedure for Monitoring the Process of Behavior of Thermal Cracking in Concrete Gravity Dams: A Case Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20de%20Paula%20Lacerda%20Santos">Adriana de Paula Lacerda Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruna%20Godke"> Bruna Godke</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauro%20Lacerda%20Santos%20Filho"> Mauro Lacerda Santos Filho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several dams in the world have already collapsed, causing environmental, social and economic damage. The concern to avoid future disasters has stimulated the creation of a great number of laws and rules in many countries. In Brazil, Law 12.334/2010 was created, which establishes the National Policy on Dam Safety. Overall, this policy requires the dam owners to invest in the maintenance of their structures and to improve its monitoring systems in order to provide faster and straightforward responses in the case of an increase of risks. As monitoring tools, visual inspections has provides comprehensive assessment of the structures performance, while auscultation’s instrumentation has added specific information on operational or behavioral changes, providing an alarm when a performance indicator exceeds the acceptable limits. These limits can be set using statistical methods based on the relationship between instruments measures and other variables, such as reservoir level, time of the year or others instruments measuring. Besides the design parameters (uplift of the foundation, displacements, etc.) the dam instrumentation can also be used to monitor the behavior of defects and damage manifestations. Specifically in concrete gravity dams, one of the main causes for the appearance of cracks, are the concrete volumetric changes generated by the thermal origin phenomena, which are associated with the construction process of these structures. Based on this, the goal of this research is to propose a monitoring process of the thermal cracking behavior in concrete gravity dams, through the instrumentation data analysis and the establishment of control values. Therefore, as a case study was selected the Block B-11 of José Richa Governor Dam Power Plant, that presents a cracking process, which was identified even before filling the reservoir in August’ 1998, and where crack meters and surface thermometers were installed for its monitoring. Although these instruments were installed in May 2004, the research was restricted to study the last 4.5 years (June 2010 to November 2014), when all the instruments were calibrated and producing reliable data. The adopted method is based on simple linear correlations procedures to understand the interactions among the instruments time series, verifying the response times between them. The scatter plots were drafted from the best correlations, which supported the definition of the limit control values. Among the conclusions, it is shown that there is a strong or very strong correlation between ambient temperature and the crack meters and flowmeters measurements. Based on the results of the statistical analysis, it was possible to develop a tool for monitoring the behavior of the case study cracks. Thus it was fulfilled the goal of the research to develop a proposal for a monitoring process of the behavior of thermal cracking in concrete gravity dams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20gravity%20dam" title="concrete gravity dam">concrete gravity dam</a>, <a href="https://publications.waset.org/abstracts/search?q=dams%20safety" title=" dams safety"> dams safety</a>, <a href="https://publications.waset.org/abstracts/search?q=instrumentation" title=" instrumentation"> instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20linear%20correlation" title=" simple linear correlation"> simple linear correlation</a> </p> <a href="https://publications.waset.org/abstracts/39742/procedure-for-monitoring-the-process-of-behavior-of-thermal-cracking-in-concrete-gravity-dams-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39742.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">292</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">214</span> Application of NBR 14861: 2011 for the Design of Prestress Hollow Core Slabs Subjected to Shear </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20Aparecida%20Vieira%20Fran%C3%A7a">Alessandra Aparecida Vieira França</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20de%20Paula%20Lacerda%20Santos"> Adriana de Paula Lacerda Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauro%20Lacerda%20Santos%20Filho"> Mauro Lacerda Santos Filho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research i to study the behavior of precast prestressed hollow core slabs subjected to shear. In order to achieve this goal, shear tests were performed using hollow core slabs 26,5cm thick, with and without a concrete cover of 5 cm, without cores filled, with two cores filled and three cores filled with concrete. The tests were performed according to the procedures recommended by FIP (1992), the EN 1168:2005 and following the method presented in Costa (2009). The ultimate shear strength obtained within the tests was compared with the values of theoretical resistant shear calculated in accordance with the codes, which are being used in Brazil, noted: NBR 6118:2003 and NBR 14861:2011. When calculating the shear resistance through the equations presented in NBR 14861:2011, it was found that provision is much more accurate for the calculation of the shear strength of hollow core slabs than the NBR 6118 code. Due to the large difference between the calculated results, even for slabs without cores filled, the authors consulted the committee that drafted the NBR 14861:2011 and found that there is an error in the text of the standard, because the coefficient that is suggested, actually presents the double value than the needed one! The ABNT, later on, soon issued an amendment of NBR 14861:2011 with the necessary corrections. During the tests for the present study, it was confirmed that the concrete filling the cores contributes to increase the shear strength of hollow core slabs. But in case of slabs 26,5 cm thick, the quantity should be limited to a maximum of two cores filled, because most of the results for slabs with three cores filled were smaller. This confirmed the recommendation of NBR 14861:2011which is consistent with standard practice. After analyzing the configuration of cracking and failure mechanisms of hollow core slabs during the shear tests, strut and tie models were developed representing the forces acting on the slab at the moment of rupture. Through these models the authors were able to calculate the tensile stress acting on the concrete ties (ribs) and scaled the geometry of these ties. The conclusions of the research performed are the experiments results have shown that the mechanism of failure of the hollow-core slabs can be predicted using the strut-and-tie procedure, within a good range of accuracy. In addition, the needed of the correction of the Brazilian standard to review the correction factor σcp duplicated (in NBR14861/2011), and the limitation of the number of cores (Holes) to be filled with concrete, to increase the strength of the slab for the shear resistance. It is also suggested the increasing the amount of test results with 26.5 cm thick, and a larger range of thickness slabs, in order to obtain results of shear tests with cores concreted after the release of prestressing force. Another set of shear tests on slabs must be performed in slabs with cores filled and cover concrete reinforced with welded steel mesh for comparison with results of theoretical values calculated by the new revision of the standard NBR 14861:2011. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prestressed%20hollow%20core%20slabs" title="prestressed hollow core slabs">prestressed hollow core slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=shear" title=" shear"> shear</a>, <a href="https://publications.waset.org/abstracts/search?q=strut" title=" strut"> strut</a>, <a href="https://publications.waset.org/abstracts/search?q=tie%20models" title=" tie models"> tie models</a> </p> <a href="https://publications.waset.org/abstracts/39739/application-of-nbr-14861-2011-for-the-design-of-prestress-hollow-core-slabs-subjected-to-shear" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39739.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">333</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">213</span> Numerical Analysis of Rapid Drawdown in Dams Based on Brazilian Standards</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renato%20Santos%20Paulinelli%20Raposo">Renato Santos Paulinelli Raposo</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinicius%20Resende%20Domingues"> Vinicius Resende Domingues</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoel%20Porfirio%20Cordao%20Neto"> Manoel Porfirio Cordao Neto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rapid drawdown is one of the cases referred to ground stability study in dam projects. Due to the complexity generated by the combination of loads and the difficulty in determining the parameters, analyses of rapid drawdown are usually performed considering the immediate reduction of water level upstream. The proposal of a simulation, considering the gradual reduction in water level upstream, requires knowledge of parameters about consolidation and those related to unsaturated soil. In this context, the purpose of this study is to understand the methodology of collection and analysis of parameters to simulate a rapid drawdown in dams. Using a numerical tool, the study is complemented with a hypothetical case study that can assist the practical use of data compiled. The referenced dam presents homogeneous section composed of clay soil, a height of 70 meters, a width of 12 meters, and upstream slope with inclination 1V:3H. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dam" title="dam">dam</a>, <a href="https://publications.waset.org/abstracts/search?q=GeoStudio" title=" GeoStudio"> GeoStudio</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20drawdown" title=" rapid drawdown"> rapid drawdown</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20analysis" title=" stability analysis"> stability analysis</a> </p> <a href="https://publications.waset.org/abstracts/54879/numerical-analysis-of-rapid-drawdown-in-dams-based-on-brazilian-standards" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54879.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">253</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">212</span> Diagnosis on Environmental Impacts of Tourism at Caju Beach in Palmas, Tocantins, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mary%20L.%20G.%20S.%20Senna">Mary L.

The identification of the environmental impacts is important so that they are mitigated, and above all that the mitigating measures are applied in the area. This work aims to identify the environmental impacts generated in the Praia do Caju area in the city of Palmas/Brazil and show that the lack of structure on the beach intensifies the environmental impacts. The present work was carried out having as parameter, the typologies of exploratory and descriptive and quantitative research through a matrix of environmental impacts through direct observation and registration. The study took place during the holidays from August to December 2016 and photographic record of impacts. From the collected data it was possible to verify that Caju beach suffers constant degradation due to irregular deposition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leisure" title="leisure">leisure</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil" title=" Brazil"> Brazil</a> </p> <a href="https://publications.waset.org/abstracts/83313/diagnosis-on-environmental-impacts-of-tourism-at-caju-beach-in-palmas-tocantins-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83313.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">337</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">211</span> Career Attitudes of Human Resource Management Professionals in Portugal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Gomes">Vitor Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Jo%C3%A3o%20Santos"> Maria João Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research carried out aimed to analyze how human resources management professionals manage their careers. It investigates the protean career and boundaryless career attitudes of these professionals and the extent to which socio-demographic dimensions (salary, gender, and academic degree, amongst others) influence their attitudes. A total of 732 professionals in the field of human resources who work for other private companies in Portugal participated in this study. The results show that as far as the professionals studied are concerned, protean attitudes and boundaryless careers prevail. Other research findings show that: (1) those with higher salaries have higher levels of protean and boundaryless career attitudes; (2) male professionals and (3) with higher education have a higher prevalence of protean and boundaryless attitudes when compared to female professionals and professionals without higher education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundaryless%20careeer" title="boundaryless careeer">boundaryless careeer</a>, <a href="https://publications.waset.org/abstracts/search?q=careeer%20management" title=" careeer management"> careeer management</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20resource%20management" title=" human resource management"> human resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=protean%20career" title=" protean career"> protean career</a>, <a href="https://publications.waset.org/abstracts/search?q=portugal" title=" portugal"> portugal</a> </p> <a href="https://publications.waset.org/abstracts/143361/career-attitudes-of-human-resource-management-professionals-in-portugal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143361.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">177</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">210</span> Strengthening and Toughening of Dental Porcelain by the Inclusion of an Yttria-Stabilized Zirconia Reinforcing Phase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buno%20Henriques">Buno Henriques</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafaela%20Santos"> Rafaela Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%BAlio%20Matias%20de%20Souza"> Júlio Matias de Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipe%20Silva"> Filipe Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubens%20Nascimento"> Rubens Nascimento</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rcio%20Fredel"> Márcio Fredel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dental porcelain composites reinforced and toughened by 20 wt.% tetragonal zirconia (3Y-TZP) were processed by hot pressing at 1000°C. Two types of particles were tested: yttria-stabilized zirconia (ZrO2–3%Y2O3) agglomerates and pre-sintered yttria-stabilized zirconia (ZrO2–3%Y2O3) particles. The composites as well as the reinforcing particles were analyzed by the means of optical and Scanning Electron Microscopy (SEM), Energy Dispersion Spectroscopy (EDS) and X-Ray Diffraction (XRD). The mechanical properties were obtained by the transverse rupture strength test, Vickers indentations and fracture toughness. Wear tests were also performed on the composites and monolithic porcelain. The best mechanical and wear results were displayed by the porcelain reinforced with the pre-sintered ZrO2–3%Y2O3 particles. <p class="card-text"><strong>Keywords:</strong> <a
