Part of these studies consider the ports as business agglomerations and focuses on port governance. This is an important approach since the port performance is the result of activities performed by actors belonging to the port-logistics chain, which need to be properly coordinated. This coordination takes place through a port governance model. Given this context, this study aims to analyze the governance model of the port of Santos from the perspective of port customers. To do this, a closed-ended questionnaire based on a conceptual model that considers the key dimensions associated with port governance was applied to the international freight forwarders that operate in the port. The results show the applicability of the considered model and highlight improvement opportunities to be implemented at the port of Santos. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=port%20governance" title="port governance">port governance</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=Port%20of%20Santos" title=" Port of Santos"> Port of Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=customers%E2%80%99%20perception" title=" customers’ perception"> customers’ perception</a> </p> <a href="https://publications.waset.org/abstracts/14167/port-governance-model-by-international-freight-forwarders-point-of-view-a-study-at-port-of-santos-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14167.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">452</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">236</span> Evaluation of PTFE Composites with Mineral Tailing Considering Friction, Wear and Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B4nio%20P.%20de%20Ara%C3%BAjo%20Neto">Antônio P. de Araújo Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruy%20D.%20A.%20da%20Silva%20Neto"> Ruy D.

Similar approach should be used in assessing cellular uptake and cytotoxicity of nanoparticles. Since nanoparticles are released into the aquatic environment they may interact with existing xenobiotics. Here we used biochemical assays and quantitative proteomics to assess the cytotoxicity of silver nanoparticles (AgNP) when human hepatoma HepG2 cells were co-exposed to 2 nm AgNP together with either Cd2+ or Hg2+ ions. Time-course experiments (2h, 4h, and 24h) were conducted to assess the first response to the exposure studies. The general trend was that a synergetic toxicological response was observed in cells exposed to both AgNP and Cd2+ or Hg2+, with AgNP and Cd2+ being more toxic. This was observed by a significant increase in the ROS and superoxide level of >35% in the case of AgNP+Cd2+ compared to the sum of responses of AgNP and Cd2+, individually. Metabolic activity and viability also dropped more for AgNP+Cd2+ (>10%) than for AgNP and Cd2+ combined. We used inductively coupled plasma mass spectrometry to investigate if AgNP facilitates larger influx of toxic metal ions into HepG2 cells. Only Hg2+ ions was found to be more efficiently engulfed as the concentration of Hg2+ was found 2.8 times larger compared to exposure experiments with only Hg2+. This effect was not observed for Cd2+. We now continue with deep proteomics studies to obtain wider details on the mechanism of the toxicity related to AgNP, Cd2+, and AgNP+Cd2+, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanotoxicology" title="nanotoxicology">nanotoxicology</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=proteomics" title=" proteomics"> proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20cell%20line" title=" human cell line"> human cell line</a> </p> <a href="https://publications.waset.org/abstracts/57417/toxicological-interactions-of-silver-nanoparticles-and-non-essential-metals-in-human-hepatocarcinoma-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57417.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">348</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> Automation of Kitchen Chemical in the Textile Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luiz%20da%20Silva%20Neto">José Luiz da Silva Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Renato%20Sipelli%20Silva"> Renato Sipelli Silva</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 automation of industrial processes plays a vital role in industries today, becoming an integral and important part of the industrial process and modern production.

With this type of procedure the generated friction leads to a localized increase in temperature, which may lead to the bone necrosis. Recognizing the importance of studying this phenomenon, an experimental evaluation of the temperatures developed during the procedure of drilling bone has been done. Additionally the influence of the use of the procedure with / without additional lubrication during drilling of bone has also been done. The obtained results are presented and discussed and suggests an advantage in using additional lubrication as a way to minimize the appearance of bone tissue necrosis during bone drilling procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20necrosis" title="bone necrosis">bone necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20drilling" title=" bone drilling"> bone drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=thermography" title=" thermography"> thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/16605/induced-bone-tissue-temperature-in-drilling-procedures-a-comparative-laboratory-study-with-and-without-lubrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16605.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">598</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> Sportomics Analysis of Metabolic Responses in Olympic Sprint Canoeists</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Magno-Fran%C3%A7a">A.

Athletes compete in solo or double races of 200m and 1000m (40 sec and 240 sec, respectively). Due to its high intensity and duration, SC is extremely useful to study the blood kinetics of some metabolites in high energetic demand. Sportomics is a field of study combining “-omics” sciences with classical biochemical analyses in order to understand sports induced systemic changes. Here, we compare Sportomics findings during SC training sessions to describe metabolic responses of five top-level canoeists. Five Olympic world-class male athletes were evaluated during two days of training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochemistry%20of%20exercise" title="biochemistry of exercise">biochemistry of exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=injury%20markers" title=" injury markers"> injury markers</a>, <a href="https://publications.waset.org/abstracts/search?q=sportomics" title=" sportomics"> sportomics</a> </p> <a href="https://publications.waset.org/abstracts/28851/sportomics-analysis-of-metabolic-responses-in-olympic-sprint-canoeists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28851.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">516</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> Educational Sport and Quality of Life for Children and Teenagers from Brazilian Northeast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Hugo%20Gonzalez">Ricardo Hugo Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Figueiredo%20Vasconcelos"> Amanda Figueiredo Vasconcelos</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Loureiro%20Neto%20Monteiro"> Francisco Loureiro Neto Monteiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Yara%20Luiza%20Freitas%20Silva"> Yara Luiza Freitas Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cristina%20Lindsay"> Ana Cristina Lindsay</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rcia%20Maria%20Tavares%20Machado"> Márcia Maria Tavares Machado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of sport as an integration mean is a very important tool regarding the social involvement of children and teenagers in a vulnerability situation. This study aims to report the experiences of a multidisciplinary program that intends to improve the quality of life of children and teenagers in Fortaleza, in the Northeast of Brazil. More than 400 children and teenagers aging 11 and 16 years participated in this study. Poor communities experience many particular difficulties in the urban centers such as violence, poor housing conditions, unemployment, lack in health care and deficient physical education in school. Physical education, physiotherapy, odontology, medicine and pharmacy students are responsible for the activities in the project supervised by a general coordinator and a counselor teacher of each academic unit. There are classes about team sports like basketball and soccer. Lectures about sexual behavior and sexually transmitted diseases are ministered beside the ones about oral health education, basic life support education, first aids, use and care with pharmaceuticals and orientations about healthy nutrition. In order to get the children’s family closer, monthly informative lectures are ministered. There is also the concern about reflecting the actions and producing academic paperwork such as graduation final projects and books. The number of participants has oscillated lately, and one of the causes is the lack of practicing physical activities and sports regularly. However, 250 teenagers have participated regularly for at least two years. These teenagers have shown a healthier lifestyle and a better physical fitness profile. The resources for maintaining the project come from the Pro-Reitoria of Extension, Federal University of Ceara, as well as from the PROEXT/MEC, Federal Government. Actions of this nature need to be done thinking for long periods so the effects results can become effective. Public and private investments are needed due to low socioeconomic families who are most vulnerable and have fewer opportunities to enhance to health prevention services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20and%20teenagers" title="children and teenagers">children and teenagers</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary%20program" title=" multidisciplinary program"> multidisciplinary program</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/77112/educational-sport-and-quality-of-life-for-children-and-teenagers-from-brazilian-northeast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77112.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">242</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">230</span> Increase of Atmosphere CO2 Concentration and Its Effects on Culture/Weed Interaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20I.%20Santos">J.

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">229</span> Multimodal Ophthalmologic Evaluation Can Detect Retinal Injuries in Asymptomatic Patients With Primary Antiphospholipid Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taurino%20S.%20R.%20Neto">Taurino S.

Methods: A complete structural and functional ophthalmological evaluation using OCTA and microperimetry (MP) exam in patients with PAPS, followed at a tertiary rheumatology outpatient clinic, was performed. All ophthalmologic manifestations were recorded and then statistical analysis was performed for comparative purposes; p <0.05 was considered statistically significant. Results: 104 eyes of 52 subjects (26 patients with PAPS without ocular complaints and 26 healthy individuals) were included. Among PAPS patients, 21 were female (80.8%) and 21 (80.8%) were Caucasians. Thrombotic PAPS was the main clinical criteria manifestation (100%); 65.4% had venous and 34.6% had arterial thrombosis. Obstetrical criteria were present in 34.6% of all thrombotic PAPS patients. Lupus anticoagulant was present in all patients. 19.2% of PAPS patients presented ophthalmologic findings against none of the healthy individuals. The most common retinal change was paracentral acute middle maculopathy (PAMM) (3 patients, 5 eyes), followed by drusen-like deposits (1 patient, 2 eyes) and pachychoroid pigment epitheliopathy (1 patient, 1 eye). Systemic hypertension and hyperlipidaemia were present in 100% of the PAPS patients with PAMM, while only six patients (26.1%) with PAPS without PAMM presented these two risk factors together. In the quantitative OCTA evaluation, we found significant differences between PAPS patients and controls in both the superficial vascular complex (SVC) and deep vascular complex (DVC) in the high-speed protocol, as well as in the SVC in the high-resolution protocol. In the analysis of the foveal avascular zone (FAZ) parameters, the PAPS group had a larger area of FAZ in the DVC using the high-speed method compared to the control group (p=0.047). In the quantitative analysis of the MP, the PAPS group had lower central (p=0.041) and global (p<0.001) retinal sensitivity compared to the control group, as well as in the sector analysis, with the exception of the inferior sector. In the quantitative evaluation of fixation stability, there was a trend towards worse stability in the PAPS subgroup with PAMM in both studied methods. Conclusions: PAMM was observed in 11.5% of PAPS patients with no previous ocular complaints. Systemic hypertension concomitant with hyperlipidemia was the most commonly associated risk factor for PAMM in patients with PAPS. PAPS patients present lower vascular density and retinal sensitivity compared to the control group, even in patients without PAMM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiphospholipid%20syndrome" title="antiphospholipid syndrome">antiphospholipid syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20coherence%20angio%20tomography" title=" optical coherence angio tomography"> optical coherence angio tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20coherence%20tomography" title=" optical coherence tomography"> optical coherence tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=retina" title=" retina"> retina</a> </p> <a href="https://publications.waset.org/abstracts/166120/multimodal-ophthalmologic-evaluation-can-detect-retinal-injuries-in-asymptomatic-patients-with-primary-antiphospholipid-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166120.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">80</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">228</span> Development of Ferrous-Aluminum Alloys from Recyclable Material by High Energy Milling </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arnold%20S.%20Freitas%20Neto">Arnold S.

The present work shows the development of the prototype of a robotic manipulator driven by a Programmable Logic Controller (PLC), having two degrees of freedom, which allows the movement and displacement of mechanical parts, tools, and objects in general of small size, through an electronic system. The aim is to study direct and inverse kinematics of the robotic manipulator to describe the translation and rotation between two adjacent links of the robot through the Denavit-Hartenberg parameters. Currently, due to the many resources that microcomputer systems offer us, robotics is going through a period of continuous growth that will allow, in a short time, the development of intelligent robots with the capacity to perform operations that require flexibility, speed and precision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denavit-Hartenberg" title="Denavit-Hartenberg">Denavit-Hartenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20and%20inverse%20kinematics" title=" direct and inverse kinematics"> direct and inverse kinematics</a>, <a href="https://publications.waset.org/abstracts/search?q=microcontrollers" title=" microcontrollers"> microcontrollers</a>, <a href="https://publications.waset.org/abstracts/search?q=robotic%20manipulator" title=" robotic manipulator"> robotic manipulator</a> </p> <a href="https://publications.waset.org/abstracts/63205/technological-development-and-implementation-of-a-robotic-arm-motioned-by-programmable-logic-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63205.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">347</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> 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">225</span> Investigation of Self-Assembling of Maghemite Nanoparticles into Chain–Like Structures Using Birefringence Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20R.%20Stein%3B%20K.%20Skeff%20Neto">C.

The intestinal enzymes acid and alkaline phosphatase (ACP and ALP, respectively), non-specific esterase (NSE), lipase (LIP), dipeptidyl aminopeptidase IV (DAP IV) and leucine aminopeptidase (LAP) were studied using histochemistry in four intestinal segments (S1, S2, S3 and posterior intestine). Weak proteolitic activity was observed in all intestinal segments for DAP IV and LAP. The activity of NSE and LIP was also weak in all intestines, except for the moderate activity of NSE in the S2 of 20% LBC group after 30 days and in the S1 of 0% LBC group after 60 days. The ACP was detected only in the S2 and S3 of the 10% LBC group after 30 days. Moderate and strong staining was observed in the first three intestinal segments for ALP and weak activity in the posterior intestine. The activity of DAP IV, LAP and ALP were also present in the cytoplasm of the enterocytes. In the present results, bovine colostrum feeding did not cause alterations in activity of intestinal enzymes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carnivorous%20fish" title="carnivorous fish">carnivorous fish</a>, <a href="https://publications.waset.org/abstracts/search?q=enterocyte" title=" enterocyte"> enterocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20epithelium" title=" intestinal epithelium"> intestinal epithelium</a>, <a href="https://publications.waset.org/abstracts/search?q=teleost" title=" teleost"> teleost</a> </p> <a href="https://publications.waset.org/abstracts/9534/histochemistry-of-intestinal-enzymes-of-juvenile-dourado-salminus-brasiliensis-fed-bovine-colostrum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9534.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">329</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> Broiler Chickens Meat Qualities and Death on Arrival (DOA) In-Transit in Brazilian Tropical Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arlan%20S.%20Freitas">Arlan S.

In this particular region routinely the season is divided into dry and wet seasons. Three loads of 4,100 forty seven days old broiler were monitored from farm to slaughterhouse in a distance of 273 km (320 min), morning periods of August, September and October 2015 rainy days. Meat qualities were evaluated by determining the occurrence of PSE (pale, soft, exudative) meat and DFD (dark, firm, dry) meat. The percentage of DOA per loaded truck was determined by counting the dead broiler during the hanging step at the slaughtering plant. Results showed the occurrence of 26.30% of PSE and 2.49% of DFD and 0.45% of DOA. By having PSE- and DFD- meat means that the birds were under thermal and cold stress leading as consequence to a relative high DOA index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20welfare" title="animal welfare">animal welfare</a>, <a href="https://publications.waset.org/abstracts/search?q=DFD" title=" DFD"> DFD</a>, <a href="https://publications.waset.org/abstracts/search?q=microclimatic%20profile" title=" microclimatic profile"> microclimatic profile</a>, <a href="https://publications.waset.org/abstracts/search?q=PSE" title=" PSE"> PSE</a> </p> <a href="https://publications.waset.org/abstracts/46722/broiler-chickens-meat-qualities-and-death-on-arrival-doa-in-transit-in-brazilian-tropical-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46722.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">410</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> Application of the Least Squares Method in the Adjustment of Chlorodifluoromethane (HCFC-142b) Regression Models </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20J.%20de%20Bessa%20Neto">L.

Damage to the ozone layer is one of them. The objective of this work is to use the Least Squares Method, considering the linear, exponential, logarithmic, power and polynomial models of the second degree, to analyze through the coefficient of determination (R²), which model best fits the behavior of the chlorodifluoromethane (HCFC-142b) in parts per trillion between 1992 and 2018, as well as estimates of future concentrations between 5 and 10 periods, i.e. the concentration of this pollutant in the years 2023 and 2028 in each of the adjustments. A total of 809 observations of the concentration of HCFC-142b in one of the monitoring stations of gases precursors of the deterioration of the ozone layer during the period of time studied were selected and, using these data, the statistical software Excel was used for make the scatter plots of each of the adjustment models. With the development of the present study, it was observed that the logarithmic fit was the model that best fit the data set, since besides having a significant R² its adjusted curve was compatible with the natural trend curve of the phenomenon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlorodifluoromethane%20%28HCFC-142b%29" title="chlorodifluoromethane (HCFC-142b)">chlorodifluoromethane (HCFC-142b)</a>, <a href="https://publications.waset.org/abstracts/search?q=ozone" title=" ozone"> ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20squares%20method" title=" least squares method"> least squares method</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20models" title=" regression models"> regression models</a> </p> <a href="https://publications.waset.org/abstracts/104490/application-of-the-least-squares-method-in-the-adjustment-of-chlorodifluoromethane-hcfc-142b-regression-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104490.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">124</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">221</span> Effect of Fibres-Chemical Treatment on the Thermal Properties of Natural Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20S.%20S.%20Neto">J.

In addition to increasing concern about the development of environmentally friendly materials that reduce, energy costs and reduces environmental impact in the production of these products, as well as reducing CO2 emissions. Natural fibers offer a great alternative to replace synthetic fibers, totally or partially, because of their low cost and their renewable source. The purpose of this research is to study the effect of surface chemical treatment on the thermal properties of hybrid fiber reinforced natural fibers (NFRC), jute + ramie, jute + sisal, jute + curauá, and jute fiber in polymer matrices. Two types of chemical treatment: alkalinization and silanization were employed, besides the condition without treatment. Differential scanning calorimetry (DSC), thermogravimetry (TG) and dynamic-mechanical analysis (DMA) were performed to explore the thermal stability and weight loss in the natural fiber reinforced composite as a function of chemical treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20treatment" title="chemical treatment">chemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20composite" title=" hybrid composite"> hybrid composite</a>, <a href="https://publications.waset.org/abstracts/search?q=jute" title=" jute"> jute</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal" title=" thermal"> thermal</a> </p> <a href="https://publications.waset.org/abstracts/83228/effect-of-fibres-chemical-treatment-on-the-thermal-properties-of-natural-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83228.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">220</span> Simulator Dynamic Positioning System with Azimuthal Thruster</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robson%20C.%20Santos">Robson C.

However, due to the low performance of photovoltaic panels, technologies need to be sought to maximize the production of electricity. In this regard, the present study aims to develop a prototype of solar tracker for didactics applications, controlled with the Arduino® platform, that enables the movement of photovoltaic plates in relation to the sun positions throughout the day through an electromechanical system, optimizing, thus, the efficiency of solar photovoltaic generation and improvements for the photovoltaic effect. The solar tracking technology developed in this work was presented of the shape oral and practical in two middle schools in the municipality of Mossoró/RN, being one of the public network and other of the private network, always keeping the average age of the students, in the case, around 16 years, contemplating an average of 60 students in each of the visits. Thus, it is concluded that the present study contributed substantially to the dissemination of knowledge concerning the photovoltaic solar generation, as well as the study of solar trackers, thus arousing the interest and curiosity of the students regarding the thematic approached. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20energy" title="alternative energy">alternative energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20tracker" title=" solar tracker"> solar tracker</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20panels" title=" photovoltaic panels"> photovoltaic panels</a> </p> <a href="https://publications.waset.org/abstracts/119607/development-of-one-axis-didactic-solar-tracker-for-photovoltaic-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119607.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">147</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">218</span> Genetic Parameters as Indicators of Sustainability and Diversity of Schinus terebinthifolius Populations in the Riparian Area of the São Francisco River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20Silva-Mann">Renata Silva-Mann</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheila%20Val%C3%A9ria%20%C3%81lvares%20Carvalho"> Sheila Valéria Álvares Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Rob%C3%A9rio%20Anast%C3%A1cio%20Ferreira"> Robério Anastácio Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Jane%20Gomes"> Laura Jane Gomes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is growing interest in defining indicators of sustainability, which are important for monitoring the conservation of native forests, particularly in areas of permanent protection. These indicators are references for assessing the state of the forest and the status of the depredated area and its ability to maintain species populations. The aim of the present study was to select genetic parameters as indicators of sustainability for Schinus terebinthifolius Raddi. Fragments located in riparian areas between the Sergipe and Alagoas States in Brazil. This species has been exploited for traditional communities, which represent 20% of the incoming. This study was carried out using the indicators suggested by the Organization for Economic Cooperation and Development, which were identified as Driving-Pressure-State-Impact-Response (DPSIR) factors. The genetic parameters were obtained in five populations located on the shores and islands of the São Francisco River, one of the most important rivers in Brazil. The framework for Schinus conservation suggests seventeen indicators of sustainability. In accordance with genetic parameters, the populations are isolated, and these genetic parameters can be used to monitor the sustainability of those populations in riparian area with the aim of defining strategies for forest restoration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alleles" title="alleles">alleles</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20markers" title=" molecular markers"> molecular markers</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/1658/genetic-parameters-as-indicators-of-sustainability-and-diversity-of-schinus-terebinthifolius-populations-in-the-riparian-area-of-the-sao-francisco-river" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1658.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">303</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">217</span> Tape-Shaped Multiscale Fiducial Marker: A Design Prototype for Indoor Localization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcell%20Serra%20de%20Almeida%20Martins">Marcell Serra de Almeida Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Benedito%20de%20Souza%20Ribeiro%20Neto"> Benedito de Souza Ribeiro Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerson%20Lima%20Serejo"> Gerson Lima Serejo</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gustavo%20Resque%20Dos%20Santos"> Carlos Gustavo Resque Dos Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indoor positioning systems use sensors such as Bluetooth, ZigBee, and Wi-Fi, as well as cameras for image capture, which can be fixed or mobile. These computer vision-based positioning approaches are low-cost to implement, mainly when it uses a mobile camera. The present study aims to create a design of a fiducial marker for a low-cost indoor localization system. The marker is tape-shaped to perform a continuous reading employing two detection algorithms, one for greater distances and another for smaller distances. Therefore, the location service is always operational, even with variations in capture distance. A minimal localization and reading algorithm were implemented for the proposed marker design, aiming to validate it. The accuracy tests consider readings varying the capture distance between [0.5, 10] meters, comparing the proposed marker with others. The tests showed that the proposed marker has a broader capture range than the ArUco and QRCode, maintaining the same size. Therefore, reducing the visual pollution and maximizing the tracking since the ambient can be covered entirely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiscale%20recognition" title="multiscale recognition">multiscale recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20localization" title=" indoor localization"> indoor localization</a>, <a href="https://publications.waset.org/abstracts/search?q=tape-shaped%20marker" title=" tape-shaped marker"> tape-shaped marker</a>, <a href="https://publications.waset.org/abstracts/search?q=fiducial%20marker" title=" fiducial marker"> fiducial marker</a> </p> <a href="https://publications.waset.org/abstracts/163542/tape-shaped-multiscale-fiducial-marker-a-design-prototype-for-indoor-localization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163542.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">134</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">216</span> Modelling Ibuprofen with Human Albumin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20L.%20Fulco">U.

Crystallographic data for the IBU–HSA supramolecular complex shows that the ligand is confined to a large cavity at the subdomain IIIA and at the interface between the subdomains IIA and IIB, whose binding sites are FA3/FA4 and FA6, respectively. The interaction energy between the IBU molecule and each amino acid residue of these HSA binding pockets was calculated using the Molecular Fractionation with Conjugate Caps (MFCC) approach employing a dispersion corrected exchange–correlation functional. Our investigation shows that the total interaction energy of IBU bound to HSA at binding sites of the fatty acids FA3/FA4 (FA6) converges only for a pocket radius of at least 8.5 °A, mainly due to the action of residues Arg410, Lys414 and Ser489 (Lys351, Ser480 and Leu481) and residues in nonhydrophobic domains, namely Ile388, Phe395, Phe403, Leu407, Leu430, Val433, and Leu453 (Phe206, Ala210, Ala213, and Leu327), which is unusual. Our simulations are valuable for a better understanding of the binding mechanism of IBU to albumin and can lead to the rational design and the development of novel IBU-derived drugs with improved potency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ibuprofen" title="ibuprofen">ibuprofen</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20serum%20albumin" title=" human serum albumin"> human serum albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title=" density functional theory"> density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20energies" title=" binding energies"> binding energies</a> </p> <a href="https://publications.waset.org/abstracts/46649/modelling-ibuprofen-with-human-albumin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46649.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">347</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> Spatial Variation of Trace Elements in Suspended Sediments from Urban River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Macedo%20Neto">Daniel Macedo Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandro%20Froehner"> Sandro Froehner</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sanez"> Juan Sanez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suspended sediments (SS) are an environmental constituent able to represent the effects of land use changes on watersheds. One important consideration of land use change is its implication on trace element loading. Water bodies have the capacity to retain trace elements. Spatial variation in trace elements concentrations can be associated with land occupation and sources of pollution. In this work, the spatial variation of trace elements in suspended sediments from an urban river was assessed. Time-integrated fluvial suspended sediment samples were installed in three different sites of Barigui River. The suspend solids were collected every 30 days, from May 2015 to August 2015 (total samples 12). Site P1 covers 44 km2 drainage area and has low land occupation, whilst P2 cover an area of 87 km2 and it is totally urban as P3, which area is higher than 130 km2. Trace elements (As, Cd, Cr, P, Pb and Zn) were analysed by ICP-ES. All elements analyzed showed a similar pattern, i.e., the concentration raise with the urbanization, exception for As (P1=7.75; P2=5.75; P3=5.60mg/kg). There was increase in concentration for Cd (P1=0.75; P2=0.78; P3=1.45mg/kg), Cr (P1=59.50; P2=101.75; P3=102.00 mg/kg), Zn (P1=142.25; P2=152.50; P3=223.00mg/kg), P (P1=937.50; P2=1,545.00; P3=2,355.00 mg/kg) and for Pb (P1=31.25; P2=32.75; P3=39.17±2.56 mg/kg). The variation in concentrations were as follow -27.74% (As), +93.33% (Cd), +71.43% (Cr), +151.20% (P), +25.33% (Pb) e +56.77% (Zn). Cd, Cr, P, Pb and Zn presented a clear trend of increasing the concentration from upstream to downstream. Such variation is more notorious for P, Cd and Cr, possibly due the urbanization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trace%20elements" title="trace elements">trace elements</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a>, <a href="https://publications.waset.org/abstracts/search?q=suspended%20sediments" title=" suspended sediments"> suspended sediments</a> </p> <a href="https://publications.waset.org/abstracts/50716/spatial-variation-of-trace-elements-in-suspended-sediments-from-urban-river" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50716.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">314</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> Comparing Image Processing and AI Techniques for Disease Detection in Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Daniel%20Garay%20Trindade">Luiz Daniel Garay Trindade</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20De%20Freitas%20Valle%20Neto"> Antonio De Freitas Valle Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Paulo%20Basso"> Fabio Paulo Basso</a>, <a href="https://publications.waset.org/abstracts/search?q=Elder%20De%20Macedo%20Rodrigues"> Elder De Macedo Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Maicon%20Bernardino"> Maicon Bernardino</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Welfer"> Daniel Welfer</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Muller"> Daniel Muller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agriculture plays an important role in society since it is one of the main sources of food in the world. To help the production and yield of crops, precision agriculture makes use of technologies aiming at improving productivity and quality of agricultural commodities. One of the problems hampering quality of agricultural production is the disease affecting crops. Failure in detecting diseases in a short period of time can result in small or big damages to production, causing financial losses to farmers. In order to provide a map of the contributions destined to the early detection of plant diseases and a comparison of the accuracy of the selected studies, a systematic literature review of the literature was performed, showing techniques for digital image processing and neural networks. We found 35 interesting tool support alternatives to detect disease in 19 plants. Our comparison of these studies resulted in an overall average accuracy of 87.45%, with two studies very closer to obtain 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title="pattern recognition">pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20farming" title=" smart farming"> smart farming</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20automation" title=" agricultural automation"> agricultural automation</a> </p> <a href="https://publications.waset.org/abstracts/129444/comparing-image-processing-and-ai-techniques-for-disease-detection-in-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129444.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">379</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> Intestinal Epithelium of Juvenile Dourado (Salminus brasiliensis) Fed with Bovine Colostrum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thaline%20Maira%20P.%20Cruz">Thaline Maira P.

Juveniles were fed with diets containing 0, 10 or 20% of lyophilized bovine colostrum (LBC) inclusion for either 30 or 60 days. For the histological study, the intestine was divided into three segments, S1, S2 and posterior intestine. In the S1 segment, interaction between treatment and period was observed in the number of goblet cells containing sialomucin, effect of treatment in the total number of goblet cells and effect of period in the number of goblet cells containing sulphomucins (P<0.05). In the S2 segment, effect of period was observed in the number of goblet cells containing acid, neutral and total mucins, sialomucins and Vv (P<0.05). In the posterior intestine, effect of period was observed in the thickness of muscle layer and number of goblet cells containing sialomucins and sulphomucins (P<0.05). Considering the aspects studied, the presence of lyophilized bovine colostrum in the diet did not significantly influence the enteric histological characteristics of juvenile dourado during the period of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carnivorous%20fish" title="carnivorous fish">carnivorous fish</a>, <a href="https://publications.waset.org/abstracts/search?q=goblet%20cells" title=" goblet cells"> goblet cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mucins" title=" mucins"> mucins</a>, <a href="https://publications.waset.org/abstracts/search?q=teleost" title=" teleost"> teleost</a> </p> <a href="https://publications.waset.org/abstracts/9976/intestinal-epithelium-of-juvenile-dourado-salminus-brasiliensis-fed-with-bovine-colostrum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9976.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">572</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> Early Modern Controversies of Mobility within the Spanish Empire: Francisco De Vitoria and the Peaceful Right to Travel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Salamanca">Beatriz Salamanca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In his public lecture ‘On the American Indians’ given at the University of Salamanca in 1538-39, Francisco de Vitoria presented an unsettling defense of freedom of movement, arguing that the Spanish had the right to travel and dwell in the New World, since it was considered part of the law of nations [ius gentium] that men enjoyed free mutual intercourse anywhere they went. The principle of freedom of movement brought hopeful expectations, promising to bring mankind together and strengthen the ties of fraternity. However, it led to polemical situations when those whose mobility was in question represented a harmful threat or was for some reason undesired. In this context, Vitoria’s argument has been seen on multiple occasions as a justification of the expansion of the Spanish empire. In order to examine the meaning of Vitoria’s defense of free mobility, a more detailed look at Vitoria’s text is required, together with the study of some of his earliest works, among them, his commentaries on Thomas Aquinas’s Summa Theologiae, where he presented relevant insights on the idea of the law of nations. In addition, it is necessary to place Vitoria’s work in the context of the intellectual tradition he belonged to and the responses he obtained from some of his contemporaries who were concerned with similar issues. The claim of this research is that the Spanish right to travel advocated by Vitoria was not intended to be interpreted in absolute terms, for it had to serve the purpose of bringing peace and unity among men, and could not contradict natural law. In addition, Vitoria explicitly observed that the right to travel was only valid if the Spaniards caused no harm, a condition that has been underestimated by his critics. Therefore, Vitoria’s legacy is of enormous value as it initiated a long lasting discussion regarding the question of the grounds under which human mobility could be restricted. Again, under Vitoria’s argument it was clear that this freedom was not absolute, but the controversial nature of his defense of Spanish mobility demonstrates how difficult it was and still is to address the issue of the circulation of peoples across frontiers, and shows the significance of this discussion in today’s globalized world, where the rights and wrongs of notions like immigration, international trade or foreign intervention still lack sufficient consensus. This inquiry about Vitoria’s defense of the principle of freedom of movement is being placed here against the background of the history of political thought, political theory, international law, and international relations, following the methodological framework of contextual history of the ‘Cambridge School’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20de%20Vitoria" title="Francisco de Vitoria">Francisco de Vitoria</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom%20of%20movement" title=" freedom of movement"> freedom of movement</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20of%20nations" title=" law of nations"> law of nations</a>, <a href="https://publications.waset.org/abstracts/search?q=ius%20gentium" title=" ius gentium"> ius gentium</a>, <a href="https://publications.waset.org/abstracts/search?q=Spanish%20empire" title=" Spanish empire"> Spanish empire</a> </p> <a href="https://publications.waset.org/abstracts/35518/early-modern-controversies-of-mobility-within-the-spanish-empire-francisco-de-vitoria-and-the-peaceful-right-to-travel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35518.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">366</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> Numerical Resolving of Net Faradaic Current in Fast-Scan Cyclic Voltammetry Considering Induced Charging Currents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Wosiak">Gabriel Wosiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Dyovani%20Coelho"> Dyovani Coelho</a>, <a href="https://publications.waset.org/abstracts/search?q=Evaldo%20B.%20Carneiro-Neto"> Evaldo B.

Lopes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the theoretical and experimental effects of induced charging currents on fast-scan cyclic voltammetry (FSCV) are investigated. Induced charging currents arise from the effect of ohmic drop in electrochemical systems, which depends on the presence of an uncompensated resistance. They cause the capacitive contribution to the total current to be different from the capacitive current measured in the absence of electroactive species. The paper shows that the induced charging current is relevant when the capacitive current magnitude is close to the total current, even for systems with low time constant. In these situations, the conventional background subtraction method may be inaccurate. A method is developed that separates the faradaic and capacitive currents by using a combination of voltametric experimental data and finite element simulation, by the obtention of a potential-dependent capacitance. The method was tested in a standard electrochemical cell with Platinum ultramicroelectrodes, in different experimental conditions as well in previously reported data in literature. The proposed method allows the real capacitive current to be separated even in situations where the conventional background subtraction method is clearly inappropriate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitive%20current" title="capacitive current">capacitive current</a>, <a href="https://publications.waset.org/abstracts/search?q=fast-scan%20cyclic%20voltammetry" title=" fast-scan cyclic voltammetry"> fast-scan cyclic voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=finite-element%20method" title=" finite-element method"> finite-element method</a>, <a href="https://publications.waset.org/abstracts/search?q=electroanalysis" title=" electroanalysis"> electroanalysis</a> </p> <a href="https://publications.waset.org/abstracts/172239/numerical-resolving-of-net-faradaic-current-in-fast-scan-cyclic-voltammetry-considering-induced-charging-currents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172239.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">75</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> Degradation of Amitriptyline Hydrochloride, Methyl Salicylate and 2-Phenoxyethanol in Water Systems by the Combination UV/Cl2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Javier%20Benitez">F.

The influence of pH, initial chlorine concentration and nature of the contaminants was firstly explored. The trend for the reactivity of the selected compounds was deduced: amitriptyline hydrochloride > methyl salicylate > 2-phenoxyethanol. A later kinetic study was carried out and focused on the specific evaluation of the first-order rate constants and the determination of the partial contribution to the global reaction of the direct photochemical pathway and the radical pathway. A comparison between the rate constant values among photochemical experiments without and with the presence of Cl<sub>2</sub> reveals a clear increase in the oxidation efficiency of the combined process with respect to the photochemical reaction alone. In a second stage, the simultaneous oxidation of mixtures of the selected contaminants in several types of water (ultrapure water, surface water from a reservoir, and two secondary effluents) was also performed by the same combination UV/Cl<sub>2 </sub>under more realistic operating conditions. The efficiency of this combined system UV/Cl<sub>2</sub> was compared to other oxidants such as the UV/S<sub>2</sub>O<sub>8</sub><sup>2- </sup>and UV/H<sub>2</sub>O<sub>2</sub> AOPs. Results confirmed that the UV/Cl<sub>2</sub> system provides higher elimination efficiencies among the AOPs tested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emerging%20contaminants" title="emerging contaminants">emerging contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%2Fchlorine%20advanced%20oxidation%20process" title=" UV/chlorine advanced oxidation process"> UV/chlorine advanced oxidation process</a>, <a href="https://publications.waset.org/abstracts/search?q=amitriptyline" title=" amitriptyline"> amitriptyline</a>, <a href="https://publications.waset.org/abstracts/search?q=methyl%20salicylate" title=" methyl salicylate"> methyl salicylate</a>, <a href="https://publications.waset.org/abstracts/search?q=2-phenoxyethanol" title=" 2-phenoxyethanol"> 2-phenoxyethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorination" title=" chlorination"> chlorination</a>, <a href="https://publications.waset.org/abstracts/search?q=photolysis" title=" photolysis"> photolysis</a> </p> <a href="https://publications.waset.org/abstracts/51159/degradation-of-amitriptyline-hydrochloride-methyl-salicylate-and-2-phenoxyethanol-in-water-systems-by-the-combination-uvcl2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51159.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">209</span> Strategies for Student Recruitment in Civil Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Ribeiro">Diogo Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Teresa%20Neto"> Teresa Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Santos"> Ricardo Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Portela"> Maria Portela</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Trinc%C3%A3o"> Alexandra Trincão</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article describes a set of innovating student recruitment strategies in a 1st cycle course of Civil Engineering, in particular the Civil Engineering Degree from the School of Engineering - Polytechnic of Porto (ISEP-PP). The strategies described were two-fold, targeting, for one, the increment on the number of admissions for the degree’s first year and two, promoting the re-entry of students who, for whatever reason, interrupted their studies. For the first objective, teacher-student binomials were set, whilst for the second, personalized contacts and assistance were provided. The main initiatives were promoted by the team of degree directors and were upheld with the participation and in consonance with the School’s external relations office. These initiatives were put forward as an attempt to minimize the impact of a national and international crisis on the AEC industry when the sustainability of the course was at risk. The implementation of these strategies was assessed on basis of a statistical analysis of the data collected from official sources and by surveys promoted. The results showed that the re-entry boost of former students, attending classes scattered on the three curricular years, secured registrations on some Curricular Units (UC’s) which more than doubled their numbers. Accompanied by a still incipient but regained interest on Civil Engineering it was possible in the short span of three years to reset the number of new students from less than 10 to the currently maximum allowed of 75, and so invert the tendency of an abrupt decline on the total number of students enrolled on the degree. <p class="card-text"><strong>Keywords:</strong> <a
