legislation and the greater demand of the population regard to gas emissions and their effects on the environment as well as on human health make the automotive industry reinforce research focused on reducing levels of contamination. This reduction can be achieved through the implementation of improvements in internal combustion engines in such a way that they promote the reduction of both specific fuel consumption and air pollutant emissions. These improvements can be obtained through numerical simulation, which is a technique that works together with experimental tests. The aim of this paper is to build, with support of the GT-Suite software, a one-dimensional model of a single-cylinder research engine to analyze the impact of the variation of swirl and tumble coefficients on the performance and on the air pollutant emissions of an engine. Initially, the discharge coefficient is calculated through the software Converge CFD 3D, given that it is an input parameter in GT-Power. Mesh sensitivity tests are made in 3D geometry built for this purpose, using the mass flow rate in the valve as a reference. In the one-dimensional simulation is adopted the non-predictive combustion model called Three Pressure Analysis (TPA) is, and then data such as mass trapped in cylinder, heat release rate, and accumulated released energy are calculated, aiming that the validation can be performed by comparing these data with those obtained experimentally. Finally, the swirl and tumble coefficients are introduced in their corresponding objects so that their influences can be observed when compared to the results obtained previously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1D%20simulation" title="1D simulation">1D simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=single-cylinder%20research%20engine" title=" single-cylinder research engine"> single-cylinder research engine</a>, <a href="https://publications.waset.org/abstracts/search?q=swirl%20coefficient" title=" swirl coefficient"> swirl coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20pressure%20analysis" title=" three pressure analysis"> three pressure analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=tumble%20coefficient" title=" tumble coefficient"> tumble coefficient</a> </p> <a href="https://publications.waset.org/abstracts/156565/a-one-dimensional-modeling-analysis-of-the-influence-of-swirl-and-tumble-coefficient-in-a-single-cylinder-research-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156565.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">105</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">155</span> Multidisciplinary Rehabilitation Algorithm after Mandibular Resection for Ameloblastoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20de%20Almeida%20Dultra">Joaquim de Almeida Dultra</a>, <a href="https://publications.waset.org/abstracts/search?q=Daiana%20Cristina%20Pereira%20Santana"> Daiana Cristina Pereira Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1tima%20Karoline%20Alves%20Ara%C3%BAjo%20Dultra"> Fátima Karoline Alves Araújo Dultra</a>, <a href="https://publications.waset.org/abstracts/search?q=Liliane%20Akemi%20Kawano%20Shibasaki"> Liliane Akemi Kawano Shibasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Machado%20Mendes%20de%20Carvalho"> Mariana Machado Mendes de Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ieda%20Margarida%20Cruso%C3%A9%20Rocha%20Rebello"> Ieda Margarida Crusoé Rocha Rebello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Defects originating from mandibular resections can cause significant functional impairment and facial disharmony, and they have complex rehabilitation. The aim of this report is to demonstrate the authors' experience facing challenging rehabilitation after mandibular resection in a patient with ameloblastoma. Clinical and surgical steps are described simultaneously, highlighting the adaptation of the final fixed prosthesis, reported in an unprecedented way in the literature. A 37-year-old male patient was seen after a sports accident, where a pathological fracture in the symphysis and left mandibular body was identified, where a large radiolucent lesion was found. The patient underwent resection, bone graft, distraction osteogenesis, rehabilitation with dental implants, prosthesis, and finally, orofacial harmonization, in an interval of six years. Rehabilitation should consider the patient's needs individually and should have as the main objective to provide similar aesthetics and function to that present before the disease. We also emphasize the importance of interdisciplinary work during the course of rehabilitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ameloblastoma" title="ameloblastoma">ameloblastoma</a>, <a href="https://publications.waset.org/abstracts/search?q=mandibular%20reconstruction" title=" mandibular reconstruction"> mandibular reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=distraction%20osteogenesis" title=" distraction osteogenesis"> distraction osteogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20implants.%20dental%20prosthesis" title=" dental implants. dental prosthesis"> dental implants. dental prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=implant-supported" title=" implant-supported"> implant-supported</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20outcome" title=" treatment outcome"> treatment outcome</a> </p> <a href="https://publications.waset.org/abstracts/152841/multidisciplinary-rehabilitation-algorithm-after-mandibular-resection-for-ameloblastoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152841.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">154</span> Phyllantus nuriri Protect against Fe2+ and SNP Induced Oxidative Damage in Mitochondrial Rich Fractions of Rats Brain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Olalekan%20Elekofehinti">Olusola Olalekan Elekofehinti</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Gbadura%20Adanlawo"> Isaac Gbadura Adanlawo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Batista%20Teixeira%20Rocha"> Joao Batista Teixeira Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We evaluated the potential neuroprotective effect of Phyllantus nuriri against Fe2+ and SNP induced oxidative stress in mitochondria of rats brain. Cellular viability was assessed by MTT reduction, reactive oxygen species (ROS) generation was measured using the probe 2,7-dichlorofluorescein diacetate (DCFH-DA). Glutathione content was measured using dithionitrobenzoic acid (DTNB). Fe2+ (10µM) and SNP (5µM) significantly decreased mitochondrial activity, assessed by MTT reduction assay, in a dose-dependent manner, this occurred in parallel with increased glutathione oxidation, ROS production and lipid peroxidation end-products (thiobarbituric acid reactive substances, TBARS). The co-incubation with methanolic extract of Phyllantus nuriri (10-100 µg/ml) reduced the disruption of mitochondrial activity, gluthathione oxidation, ROS production as well as the increase in TBARS levels caused by both Fe2+ and SNP in a dose dependent manner. HPLC analysis of the extract revealed the presence of gallic acid (20.54±0.01), caffeic acid (7.93±0.02), rutin (25.31±0.05), quercetin (31.28±0.03) and kaemferol (14.36±0.01). This result suggests that these phytochemicals account for the protective actions of Phyllantus nuriri against Fe2+ and SNP -induced oxidative stress. Our results show that Phyllantus nuriri consist important bioactive molecules in the search for an improved therapy against the deleterious effects of Fe2+, an intrinsic producer of reactive oxygen species (ROS), that leads to neuronal oxidative stress and neurodegeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phyllantus%20niruri" title="Phyllantus niruri">Phyllantus niruri</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotection" title=" neuroprotection"> neuroprotection</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title=" mitochondria"> mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=synaptosome" title=" synaptosome"> synaptosome</a> </p> <a href="https://publications.waset.org/abstracts/20633/phyllantus-nuriri-protect-against-fe2-and-snp-induced-oxidative-damage-in-mitochondrial-rich-fractions-of-rats-brain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20633.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">359</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">153</span> Effect of Temperature on the Properties of Cement Paste Modified with Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karine%20Pimenta%20Teixeira">Karine Pimenta Teixeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Flores"> Jessica Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Isadora%20Perdig%C3%A3O%20Rocha"> Isadora PerdigãO Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20De%20S%C3%A1%20Carneiro"> Leticia De Sá Carneiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Kamali"> Mahsa Kamali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ghahremaninezhad"> Ali Ghahremaninezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advent of nanotechnology has enabled innovative solutions towards improving the behavior of infrastructure materials. Nanomaterials have the potential to revolutionize the construction industry by improving the performance and durability of construction materials, as well as imparting new functionalities to these materials. Due to variability in the environmental temperature during mixing and curing of cementitious materials in practice, it is important to understand how curing temperature influences the behavior of cementitious materials. In addition, high temperature curing is relevant in applications such as oil well cement and precast industry. Knowledge of the influence of temperature on the performance of cementitious materials modified with nanoparticles is important in the nanoengineering of cementitious materials in applications such as oil well cement and precast industry. This presentation aims to investigate the influence of temperature on the hydration, mechanical properties and durability of cementitious materials modified with TiO2 nanoparticles. It was found that temperature improved the early hydration. The cement pastes cured at high temperatures showed an increase in the compressive strength at early age but the strength gain decreased at late ages. The electrical resistivity of the cement pastes cured at high temperatures was shown to decrease more noticeably at late ages compared to that of the room temperature cured cement paste. SEM examination indicated that hydration product was more uniformly distributed in the microstructure of the cement paste cured at room temperature compared to the cement pastes cured at high temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement%20paste" title="cement paste">cement paste</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=hydration" title=" hydration"> hydration</a> </p> <a href="https://publications.waset.org/abstracts/59309/effect-of-temperature-on-the-properties-of-cement-paste-modified-with-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59309.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">317</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">152</span> Histological Characteristics of the Organs of Adult Zebrafish as a Biomarker for the Study of New Drugs with Effect on the Snake Venom of Bothrops alternatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Carlos%20Tavares%20Carvalho">Jose Carlos Tavares Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hady%20Keita"> Hady Keita</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Rocha%20Santana"> Giovanna Rocha Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Victor%20Ferreira%20Dos%20Santos"> Igor Victor Ferreira Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Rafael%20Rodriguez%20Amado"> Jesus Rafael Rodriguez Amado</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariadna%20Lafourcade%20Prada"> Ariadna Lafourcade Prada</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Maciel%20Ferreira"> Adriana Maciel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Helison%20Oliveira"> Helison Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Summary: As animal model, zebrafish can be a good opportunity to establish a profile of tissue alteration caused by Bothrops alternatus venom and to screen new anti-venom drugs. Objective: To establish tissue biomarkers from zebrafish injected by snake venom and elucidate the use of glucocorticoids in ophidic accidents. Materials and Methods: The Danio rerio fish were randomly divided into four groups: control group, venom group, Dexamethasone1h before venom injected group and Dexamethasone 1 h after venom injected group. The concentration of Bothrops alternatus venom was 0.13 mg/ml and the fish received 20µl/Fish. The Body weight measurement and histological characteristics of gills, kidneys, liver, and intestine were determinate. Results: Physical analysis shows necrosis accompanied by inflammation in animals receiving the Bothrops alternatus venom. Significant difference was observed in the variation of weight between the control group, and the groups received the venom (t student test, p < 0.05). The average histological alterations index of gill, liver, kidney or intestine was statistically higher in animals received the venom (t Student test, p < 0.05). The alterations were lower in the groups that received Dexamethasone 1h before and after venom injected compared to the group that received only the venom. Dexamethasone 1h before venom injected group had minor histopathological alterations. Conclusion: The organs of zebrafish may be a tissue biomarker of alterations from Bothrops alternatus venom and dexamethasone reduced the damage caused by this venom in the organs studied, which may suggest the use of zebrafish as animal model for research related to screening new drug against snake venom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zebrafish" title="zebrafish">zebrafish</a>, <a href="https://publications.waset.org/abstracts/search?q=snake%20venom" title=" snake venom"> snake venom</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs" title=" drugs"> drugs</a> </p> <a href="https://publications.waset.org/abstracts/53757/histological-characteristics-of-the-organs-of-adult-zebrafish-as-a-biomarker-for-the-study-of-new-drugs-with-effect-on-the-snake-venom-of-bothrops-alternatus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53757.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">151</span> The Coexistence of Dual Form of Malnutrition among Portuguese Institutionalized Elderly People</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Ca%C3%A7ador">C.

The evaluation was based on anthropometric measurements and the Mini Nutritional Assessment (MNA) score. The mean age of the subjects was 82.3 ± 6.1 years-old. Most of the elderly residents were female (72.0%). The majority had 4 years of formal education (51.9%) and was widowed (74.3%) or married (14.0%). Men presented a mean age of 81.2±8.5 years-old, weight 69.3±14.5 kg and BMI 25.33±6.5 kg/m2. In women, the mean age was 84.5±8.2 years-old, weight 61.2±14.7 kg and BMI 27.43±5.6 kg/m2. The evaluation of the nutritional status using the MNA score showed that 24.0% of the residents show a risk of undernutrition and 76.0% of them were well nourished. There was a high prevalence of obese (24.8%) and overweight residents (33.2%) according to the BMI. 7.5% were considered underweight. We also found that according to their waist circumference measurements 88.3% of the residents were at risk for cardiovascular disease (CVD) and 64.0% of them presented very high risk for CVD (WC≥88 cm for women and WC ≥102 cm for men). The present study revealed the coexistence of a dual form of malnutrition (undernourished and overweight) among the institutionalized Portuguese concomitantly with an excess of abdominal adiposity. The high prevalence of residents at high risk for CVD should not be overlooked. Given the vulnerability of the group of institutionalized elderly, our study highlights the importance of the classification of nutritional status based on both instruments: the BMI and the MNA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutritional%20satus" title="nutritional satus">nutritional satus</a>, <a href="https://publications.waset.org/abstracts/search?q=MNA" title=" MNA"> MNA</a>, <a href="https://publications.waset.org/abstracts/search?q=BMI" title=" BMI"> BMI</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly" title=" elderly"> elderly</a> </p> <a href="https://publications.waset.org/abstracts/11514/the-coexistence-of-dual-form-of-malnutrition-among-portuguese-institutionalized-elderly-people" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11514.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">324</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">150</span> Design of a 4-DOF Robot Manipulator with Optimized Algorithm for Inverse Kinematics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20G%C3%B3mez">S.

The frugal innovation is simply the use of recycled PET bottles.

The focus has been concentrated in silicate glasses although their amplified spontaneous emission is limited to a few tens of nanometers (~ 40nm). Recently, phosphate glasses have received great attention due to their potential application in optical data transmission, detection, sensors and laser detector, waveguide and optical fibers, besides its excellent physical properties such as high thermal expansion coefficients and low melting temperature. Compared with the silica glasses, phosphate glasses provide different optical properties such as, large transmission window of infrared, and good density. Research on the improvement of physical and chemical durability of phosphate glass by addition of heavy metals oxides in P2O5 has been performed. The addition of Na2O further improves the solubility of rare earths, while increasing the Al2O3 links in the P2O5 tetrahedral results in increased durability and aqueous transition temperature and a decrease of the coefficient of thermal expansion. This work describes the structural and spectroscopic characterization of a phosphate glass matrix doped with different Er (Erbium) concentrations. The phosphate glasses containing Er3+ ions have been prepared by melt technique. A study of the optical absorption, luminescence and lifetime was conducted in order to characterize the infrared emission of Er3+ ions at 1540 nm, due to the radiative transition 4I13/2 → 4I15/2. Our results indicate that the present glass is a quite good matrix for Er3+ ions, and the quantum efficiency of the 1540 nm emission was high. A quenching mechanism for the mentioned luminescence was not observed up to 2,0 mol% of Er concentration. The Judd-Ofelt parameters, radiative lifetime and quantum efficiency have been determined in order to evaluate the potential of Er3+ ions in new phosphate glass. The parameters follow the trend as Ω2 > Ω4 > Ω6. It is well known that the parameter Ω2 is an indication of the dominant covalent nature and/or structural changes in the vicinity of the ion (short range effects), while Ω4 and Ω6 intensity parameters are long range parameters that can be related to the bulk properties such as viscosity and rigidity of the glass. From the PL measurements, no red or green upconversion was measured when pumping the samples with laser excitation at 980 nm. As future prospects: Synthesize this glass system with silver in order to determine the influence of silver nanoparticles on the Er3+ ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phosphate%20glass" title="phosphate glass">phosphate glass</a>, <a href="https://publications.waset.org/abstracts/search?q=erbium" title=" erbium"> erbium</a>, <a href="https://publications.waset.org/abstracts/search?q=luminescence" title=" luminescence"> luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20system" title=" glass system"> glass system</a> </p> <a href="https://publications.waset.org/abstracts/27070/optical-and-structural-characterization-of-rare-earth-doped-phosphate-glasses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27070.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">510</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">145</span> Oxygen Transfer in Viscous Non-Newtonian Liquid in a Hybrid Bioreactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%A9rgio%20S.%20de%20Jesus">Sérgio S. de Jesus</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Santana"> Aline Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubens%20Maciel%20Filho"> Rubens Maciel Filho </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global oxygen transfer coefficient (kLa) was characterized in a mechanically agitated airlift bio reactor.

The use of any space without planning can cause impacts on the environment, which depending on the proportion may be irreversible. Buritis beach is very frequented by visitors, but it has no information on use and does not have enough infrastructure to collaborate with the preservation of the environment. Therefore, the objective of this study was to adopt a simple control list of environmental impacts in river beaches, in order to identify the environmental impacts generated in the post-holiday seasons of Buritis beach and to characterize the beach in terms of infrastructure. The holidays that carried out the analyzes were the nationals of the second half of 2017, as well as the universal fraternization holiday of 2018. The results show that the beach needs investments in its infrastructure and educational campaigns to minimize environmental impacts caused by anthropic action. <p class="card-text"><strong>Keywords:</strong> <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=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=Buritis%20Beach" title=" Buritis Beach"> Buritis Beach</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil." title=" Brazil."> Brazil.</a> </p> <a href="https://publications.waset.org/abstracts/104466/analysis-of-environmental-impacts-generated-in-the-seasons-of-holidays-from-praia-dos-buritis-in-palmas-tocantins-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104466.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">156</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">138</span> Stereoscopic Motion Design: Design Futures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Teixeira">Edgar Teixeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Eurico%20Carrapatoso"> Eurico Carrapatoso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As 3D displays become increasingly affordable, while production techniques and computational resources to create stereoscopic content being ever more accessible, a new dimension is literally introduced along with new expressive and immersive potentialities in support of designing for the screen.

In this paper, that immense text has been accessed to so as to understand the perception Internet users from all over the world have of Portugal. Ours is a quantitative and qualitative approach, as we have resorted to buzz, thematic and category analysis.

Twenty-four feedlot Ile de France lambs (average weight of 15kg and average age of 60 days) were randomized to receive the different diets and slaughtered at 32kg body weight. Increases were observed in the concentrations of the saturated pentadecanoic, heptadecanoic and arachidic fatty acids; of the monounsaturated nervonic fatty acid and of the polyunsaturated α-linolenic, ɣ-linolenic and eicosapentaenoic fatty acids. Increased conjugated linoleic acid (CLA) was also found in the meat of lambs fed on 12.5% mulberry hay. In addition, the omega-3 composition was augmented, while the omega-3/omega-6 ratio was decreased in mulberry hay-fed animals. In conclusion, a more desirable fatty acid profile was observed in lamb meat following the substitution of mulberry hay in the concentrate of fed, resulting in improved nutritional characteristics of the meat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20food" title="alternative food">alternative food</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=feedlot" title=" feedlot"> feedlot</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep%20meat" title=" sheep meat"> sheep meat</a> </p> <a href="https://publications.waset.org/abstracts/9723/fatty-acid-profile-of-meat-from-lambs-fed-on-diets-containing-mulberry-hay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9723.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">465</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">132</span> Social Networks as a Tool for Sports Marketing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rcia%20Aparecida%20Teixeira">Márcia Aparecida Teixeira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sports, in particular football, boosts considerably the financial market of a certain locality, be it city or even a country.

The application of realistic operating conditions (load and speed) to the different cases studied will provide a deeper understanding of the effects of the spark plug gap, a result of parts outwearing in most of the cases, to the development of the combustion in engine-like conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engine" title="engine">engine</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20injection" title=" direct injection"> direct injection</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion" title=" combustion"> combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20plug" title=" spark plug"> spark plug</a> </p> <a href="https://publications.waset.org/abstracts/156457/numerical-investigation-of-the-effect-of-the-spark-plug-gap-on-engine-like-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156457.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">130</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">129</span> Measurement of the Neutron Spectrum of 241AmLi and 241AmF Sources Using the Bonner Sphere Spectrometers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Rocha%20Carvalho">Victor Rocha Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Bonner Sphere Spectrometry was used to obtain the average energy, the fluence rate, and radioprotection quantities such as the personal and ambient dose equivalent of the ²⁴¹AmLi and ²⁴¹AmF isotopic neutron sources used in the Neutron Metrology Laboratory - LN. The counts of the sources were performed with six different spherical moderators around the detector. Through this, the neutron spectrum was obtained by means of the software named NeuraLN, developed by the LN, that uses the neural networks technique. The 241AmLi achieved a result close to the literature, and 241AmF, which contains few published references, acquired a result with a slight variation from the literature. Therefore, besides fulfilling its objective, the work raises questions about a possible standard of the ²⁴¹AmLi and about the lack of work with the ²⁴¹AmF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nuclear%20physics" title="nuclear physics">nuclear physics</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20metrology" title=" neutron metrology"> neutron metrology</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20spectrometry" title=" neutron spectrometry"> neutron spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=bonner%20sphere%20spectrometers" title=" bonner sphere spectrometers"> bonner sphere spectrometers</a> </p> <a href="https://publications.waset.org/abstracts/160581/measurement-of-the-neutron-spectrum-of-241amli-and-241amf-sources-using-the-bonner-sphere-spectrometers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160581.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">102</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">128</span> Integration Network ASI in Lab Automation and Networks Industrial in IFCE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Fernandes%20Teixeira%20Filho">Jorge Fernandes Teixeira Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Oliveira%20Alcantara%20Fontenele"> André Oliveira Alcantara Fontenele</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%89rick%20Arag%C3%A3o%20Ribeiro"> Érick Aragão Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The constant emergence of new technologies used in automated processes makes it necessary for teachers and traders to apply new technologies in their classes. This paper presents an application of a new technology that will be employed in a didactic plant, which represents an effluent treatment process located in a laboratory of a federal educational institution. At work were studied in the first place, all components to be placed on automation laboratory in order to determine ways to program, parameterize and organize the plant. New technologies that have been implemented to the process are basically an AS-i network and a Profinet network, a SCADA system, which represented a major innovation in the laboratory. The project makes it possible to carry out in the laboratory various practices of industrial networks and SCADA systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20networks" title=" industrial networks"> industrial networks</a>, <a href="https://publications.waset.org/abstracts/search?q=SCADA%20systems" title=" SCADA systems"> SCADA systems</a>, <a href="https://publications.waset.org/abstracts/search?q=lab%20automation" title=" lab automation"> lab automation</a> </p> <a href="https://publications.waset.org/abstracts/41367/integration-network-asi-in-lab-automation-and-networks-industrial-in-ifce" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41367.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">545</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">127</span> Endovascular Aneurysm Repair (Evar) with Endoanchors: For Tandem Aortic Abdominal Aneurysm (Aaa) with Hostile Neck & Proximal Penetrating Atherosclerotic Ulcer </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Von%20Jerick%20Tenorio">Von Jerick Tenorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonald%20Lucero"> Jonald Lucero</a>, <a href="https://publications.waset.org/abstracts/search?q=Marivic%20Vestal"> Marivic Vestal</a>, <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Tiempo"> Edwin Tiempo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In patients with hostile aortic neck anatomy, the risks of proximal seal complications and stent migration remain with EVAR despite improved endograft technology. This case report discusses how the technical challenges of the hostile neck anatomy, proximal penetrating atherosclerotic ulcer (PAU) and tortuous femoral access were addressed. The CT aortogram of a 63-year-old hypertensive and diabetic man with recurring abdominal discomfort revealed a fusiform infra-renal aneurysm measuring 8.8 cm in length and 5.7 cm in diameter. The proximal landing zone only has a 3 mm healthy neck with a conicity of > 10% and a thrombus of 4 mm thick. Proximal to the aneurysm is a PAU with a circumferential mural thrombus. The right femoral artery is tortuous with > 90o angulation. A 20% oversized Endurant II endograft and Aptus Heli-FX EndoAnchors were deployed as prophylaxis for type I endoleaks and endograft migration consequent to the conical neck and proximal aneurysm extension consequent to the PAU. A stiff Backup Meier guide wire facilitated the deployment of the endograft. Coil embolization of the right internal iliac artery was performed as prophylaxis for type II endoleaks. EndoAnchors can be used as an adjunct to EVAR as prophylaxis for proximal seal complications and stent migration in patients with hostile aortic aneurysm neck anatomy and concomitant proximal PAU. <p
