more prominent as countries move towards intellectual-based economies. Consequently, the nature and essence of the workplace needs to be reconfigured so that creativity and productivity can be better promoted at these spaces. Using a multidisciplinary approach and a user-centered methodology, combining product design, electronic engineering, software and human-computer interaction, we have designed and developed a new seat that uses embedded sensors and actuators to increase the overall well-being of its users, their productivity and their creativity. Our contribution focuses on the parameters that most affect the user’s work on these kinds of spaces, which are, according to our study, noise and temperature. We describe the design process for a new interactive seat targeted at improving workspace productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-computer%20interaction" title="human-computer interaction">human-computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=usability" title=" usability"> usability</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20interface" title=" user interface"> user interface</a>, <a href="https://publications.waset.org/abstracts/search?q=creativity" title=" creativity"> creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a> </p> <a href="https://publications.waset.org/abstracts/83453/the-design-process-of-an-interactive-seat-for-improving-workplace-productivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83453.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">221</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">633</span> The Proposal for a Framework to Face Opacity and Discrimination ‘Sins’ Caused by Consumer Creditworthiness Machines in the EU</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Jos%C3%A9%20Morgado%20Rebelo">Diogo José Morgado Rebelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Ant%C3%B3nio%20Carneiro%20Pacheco%20de%20Andrade"> Francisco António Carneiro Pacheco de Andrade</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Jorge%20Freitas%20de%20Oliveira%20Novais"> Paulo Jorge Freitas de Oliveira Novais</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Not everything in AI-power consumer credit scoring turns out to be a wonder. When using AI in Creditworthiness Assessment (CWA), opacity and unfairness ‘sins’ must be considered to the task be deemed Responsible. AI software is not always 100% accurate, which can lead to misclassification. Discrimination of some groups can be exponentiated. A hetero personalized identity can be imposed on the individual(s) affected. Also, autonomous CWA sometimes lacks transparency when using black box models. However, for this intended purpose, human analysts ‘on-the-loop’ might not be the best remedy consumers are looking for in credit. This study seeks to explore the legality of implementing a Multi-Agent System (MAS) framework in consumer CWA to ensure compliance with the regulation outlined in Article 14(4) of the Proposal for an Artificial Intelligence Act (AIA), dated 21 April 2021 (as per the last corrigendum by the European Parliament on 19 April 2024), Especially with the adoption of Art. 18(8)(9) of the EU Directive 2023/2225, of 18 October, which will go into effect on 20 November 2026, there should be more emphasis on the need for hybrid oversight in AI-driven scoring to ensure fairness and transparency. In fact, the range of EU regulations on AI-based consumer credit will soon impact the AI lending industry locally and globally, as shown by the broad territorial scope of AIA’s Art. 2. Consequently, engineering the law of consumer’s CWA is imperative. Generally, the proposed MAS framework consists of several layers arranged in a specific sequence, as follows: firstly, the Data Layer gathers legitimate predictor sets from traditional sources; then, the Decision Support System Layer, whose Neural Network model is trained using k-fold Cross Validation, provides recommendations based on the feeder data; the eXplainability (XAI) multi-structure comprises Three-Step-Agents; and, lastly, the Oversight Layer has a 'Bottom Stop' for analysts to intervene in a timely manner. From the analysis, one can assure a vital component of this software is the XAY layer. It appears as a transparent curtain covering the AI’s decision-making process, enabling comprehension, reflection, and further feasible oversight. Local Interpretable Model-agnostic Explanations (LIME) might act as a pillar by offering counterfactual insights. SHapley Additive exPlanation (SHAP), another agent in the XAI layer, could address potential discrimination issues, identifying the contribution of each feature to the prediction. Alternatively, for thin or no file consumers, the Suggestion Agent can promote financial inclusion. It uses lawful alternative sources such as the share of wallet, among others, to search for more advantageous solutions to incomplete evaluation appraisals based on genetic programming. Overall, this research aspires to bring the concept of Machine-Centered Anthropocentrism to the table of EU policymaking. It acknowledges that, when put into service, credit analysts no longer exert full control over the data-driven entities programmers have given ‘birth’ to. With similar explanatory agents under supervision, AI itself can become self-accountable, prioritizing human concerns and values. AI decisions should not be vilified inherently. The issue lies in how they are integrated into decision-making and whether they align with non-discrimination principles and transparency rules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creditworthiness%20assessment" title="creditworthiness assessment">creditworthiness assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20oversight" title=" hybrid oversight"> hybrid oversight</a>, <a href="https://publications.waset.org/abstracts/search?q=machine-centered%20anthropocentrism" title=" machine-centered anthropocentrism"> machine-centered anthropocentrism</a>, <a href="https://publications.waset.org/abstracts/search?q=EU%20policymaking" title=" EU policymaking"> EU policymaking</a> </p> <a href="https://publications.waset.org/abstracts/185890/the-proposal-for-a-framework-to-face-opacity-and-discrimination-sins-caused-by-consumer-creditworthiness-machines-in-the-eu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185890.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">34</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">632</span> Patchwork City: An Affective Map for a Patchwork Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Luc%C3%ADlia%20Borges">Maria Lucília Borges</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents the creation and design process of the "patchwork map" made for the project “Santo Amaro em Rede” (Santo Amaro on Web).

To slow disorder progression, different treatment options are now available, but in most cases, these therapeutic strategies also involve the presence of important side effects. This has led many patients to pursue complementary therapies, such as acupuncture, to alleviate PD symptoms. Therefore, an update on the efficacy of this treatment for patients of PD is of great value. This work presents a systematic review of the efficacy of acupuncture treatments in relieving PD symptoms. Methods: EMBASE, Medline, Pubmed, Science Direct, The Cochrane Library, Cochrane Central Register of Controlled Trials (Central), and Scielo databases were systematically searched from January 2011 through July 2021. Randomized controlled trials (RCTs) published in English with all types of acupuncture treatment were included. The selection and analysis of the articles were conducted by two blinding authors through the Rayyan application. Results: 720 potentially relevant articles were identified; 52 RCTs met our inclusion criteria. After the exclusion of 35, we found 17 eligible. The included RCTs reported positive effects for acupuncture plus conventional treatment compared with conventional treatment alone in the UPDRS score. Conclusions: Additional evidence should be supported by rigorous methodological strategies. Although firm conclusions cannot be drawn, acupuncture treatment, in the framework of an interdisciplinary care team, appears to have positive effects on PD symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title="systematic review">systematic review</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinson%20disease" title=" Parkinson disease"> Parkinson disease</a>, <a href="https://publications.waset.org/abstracts/search?q=acupuncture" title=" acupuncture"> acupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20Chinese%20medicine" title=" traditional Chinese medicine"> traditional Chinese medicine</a> </p> <a href="https://publications.waset.org/abstracts/158514/systematic-review-of-the-efficacy-of-traditional-chinese-medicine-in-parkinson-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158514.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">143</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">629</span> The Perspective of Waste Frying Oil in São Paulo and Its Dimensions in the Reverse Logistics of the Production of Biodiesel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Max%20Filipe%20Goncalves">Max Filipe Goncalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20Concilio"> Alessandra Concilio</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Shimada"> Rodrigo Shimada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The waste frying oil is highly pollutant when disposed incorrectly in the environment.

Magnetic resonance imaging (MRI), due to the richness in the information details provided, is the gold standard exam for diagnosis and follow-up of neurodegenerative diseases, such as MS. Brain atrophy, the gradual loss of brain volume, is quite extensive in multiple sclerosis, nearly 0.5-1.35% per year, far off the limits of normal aging. Thus, the brain volume quantification becomes an essential task for future analysis of the occurrence atrophy. The analysis of MRI has become a tedious and complex task for clinicians, who have to manually extract important information. This manual analysis is prone to errors and is time consuming due to various intra- and inter-operator variability. Nowadays, computerized methods for MRI segmentation have been extensively used to assist doctors in quantitative analyzes for disease diagnosis and monitoring. Thus, the purpose of this work was to evaluate the brain volume in MRI of MS patients. We used MRI scans with 30 slices of the five patients diagnosed with multiple sclerosis according to the McDonald criteria. The computational methods for the analysis of images were carried out in two steps: segmentation of the brain and brain volume quantification. The first image processing step was to perform brain extraction by skull stripping from the original image. In the skull stripper for MRI images of the brain, the algorithm registers a grayscale atlas image to the grayscale patient image. The associated brain mask is propagated using the registration transformation. Then this mask is eroded and used for a refined brain extraction based on level-sets (edge of the brain-skull border with dedicated expansion, curvature, and advection terms). In the second step, the brain volume quantification was performed by counting the voxels belonging to the segmentation mask and converted in cc. We observed an average brain volume of 1469.5 cc. We concluded that the automatic method applied in this work can be used for the brain extraction process and brain volume quantification in MRI. The development and use of computer programs can contribute to assist health professionals in the diagnosis and monitoring of patients with neurodegenerative diseases. In future works, we expect to implement more automated methods for the assessment of cerebral atrophy and brain lesions quantification, including machine-learning approaches.

However, the extent of injury may exceed the inherent tissue regeneration capability demanding some kind of additional intervention. In this scenario, cell therapy has emerged as a promising alternative to treat challenging bone defects. This study aimed at evaluating the effect of local injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) and adipose tissue-derived mesenchymal stem cells (AT-MSCs) on bone regeneration of rat calvaria defects. BM-MSCs and AT-MSCs were isolated and characterized by expression of surface markers; cell viability was evaluated after injection through a 21G needle. Defects of 5 mm in diameter were created in calvaria and after two weeks a single injection of BM-MSCs, AT-MSCs or vehicle-PBS without cells (Control) was carried out. Cells were tracked by bioluminescence and at 4 weeks post-injection bone formation was evaluated by micro-computed tomography (μCT) and histology, nanoindentation, and through gene expression of bone remodeling markers. The data were evaluated by one-way analysis of variance (p≤0.05). BM-MSCs and AT-MSCs presented characteristics of mesenchymal stem cells, kept viability after passing through a 21G needle and remained in the defects until day 14. In general, injection of both BM-MSCs and AT-MSCs resulted in higher bone formation compared to Control. Additionally, this bone tissue displayed elastic modulus and hardness similar to the pristine calvaria bone. The expression of all evaluated genes involved in bone formation was upregulated in bone tissue formed by BM-MSCs compared to AT-MSCs while genes involved in bone resorption were upregulated in AT-MSCs-formed bone. We show that cell therapy based on the local injection of BM-MSCs or AT-MSCs is effective in delivering viable cells that displayed local engraftment and induced a significant improvement in bone healing. Despite differences in the molecular cues observed between BM-MSCs and AT-MSCs, both cells were capable of forming bone tissue at comparable amounts and properties. These findings may drive cell therapy approaches toward the complete bone regeneration of challenging sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20therapy" title="cell therapy">cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20repair" title=" bone repair"> bone repair</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title=" cell culture"> cell culture</a> </p> <a href="https://publications.waset.org/abstracts/103816/effect-of-locally-injected-mesenchymal-stem-cells-on-bone-regeneration-of-rat-calvaria-defects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103816.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">184</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">625</span> Artificial Neural Networks and Geographic Information Systems for Coastal Erosion Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angeliki%20Peponi">Angeliki Peponi</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Morgado"> Paulo Morgado</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Trindade"> Jorge Trindade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial Neural Networks (ANNs) and Geographic Information Systems (GIS) are applied as a robust tool for modeling and forecasting the erosion changes in Costa Caparica, Lisbon, Portugal, for 2021.

Sandwell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Metropolitan Region of Sao Paulo (MRSP) has suffered from serious water scarcity. Consequently, the most convenient solution has been building wells to extract groundwater from local aquifers. However, it requires constant vigilance to prevent over extraction and future events that can pose serious threat to the population, such as subsidence. Radar imaging techniques (InSAR) have allowed continuous investigation of such phenomena. The analysis of data in the present study consists of 23 SAR images dated from October 2007 to March 2011, obtained by the ALOS-1 spacecraft. Data processing was made with the software GMTSAR, by using the InSAR technique to create pairs of interferograms with ground displacement during different time spans. First results show a correlation between the location of 102 wells registered in 2009 and signals of ground displacement equal or lower than -90 millimeters (mm) in the region. The longest time span interferogram obtained dates from October 2007 to March 2010. As a result, from that interferogram, it was possible to detect the average velocity of displacement in millimeters per year (mm/y), and which areas strong signals have persisted in the MRSP. Four specific areas with signals of subsidence of 28 mm/y to 40 mm/y were chosen to investigate the phenomenon: Guarulhos (Sao Paulo International Airport), the Greater Sao Paulo, Itaquera and Sao Caetano do Sul. The coverage area of the signals was between 0.6 km and 1.65 km of length. All areas are located above a sedimentary type of aquifer. Itaquera and Sao Caetano do Sul showed signals varying from 28 mm/y to 32 mm/y. On the other hand, the places most likely to be suffering from stronger subsidence are the ones in the Greater Sao Paulo and Guarulhos, right beside the International Airport of Sao Paulo. The rate of displacement observed in both regions goes from 35 mm/y to 40 mm/y. Previous investigations of the water use at the International Airport highlight the risks of excessive water extraction that was being done through 9 deep wells. Therefore, it is affirmed that subsidence events are likely to occur and to cause serious damage in the area. This study could show a situation that has not been explored with proper importance in the city, given its social and economic consequences. Since the data were only available until 2011, the question that remains is if the situation still persists. It could be reaffirmed, however, a scenario of risk at the International Airport of Sao Paulo that needs further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground%20subsidence" title="ground subsidence">ground subsidence</a>, <a href="https://publications.waset.org/abstracts/search?q=Interferometric%20Satellite%20Aperture%20Radar%20%28InSAR%29" title=" Interferometric Satellite Aperture Radar (InSAR)"> Interferometric Satellite Aperture Radar (InSAR)</a>, <a href="https://publications.waset.org/abstracts/search?q=metropolitan%20region%20of%20Sao%20Paulo" title=" metropolitan region of Sao Paulo"> metropolitan region of Sao Paulo</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20extraction" title=" water extraction"> water extraction</a> </p> <a href="https://publications.waset.org/abstracts/42242/satellite-interferometric-investigations-of-subsidence-events-associated-with-groundwater-extraction-in-sao-paulo-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42242.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">354</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">622</span> Analyzing the Impact of Bariatric Surgery in Obesity Associated Chronic Kidney Disease: A 2-Year Observational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Magalhaes">Daniela Magalhaes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Pedro"> Jorge Pedro</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Souteiro"> Pedro Souteiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20S.%20Neves"> Joao S.

Our aims were: (1) evaluate the impact of bariatric surgery (BS) on renal function; (2) clarify the factors determining the postoperative evolution of the glomerular filtration rate (GFR); (3) access the occurrence of oxalate-mediated renal complications. Methods: We investigated a cohort of 1448 obese patients who underwent bariatric surgery. Those with basal GFR (GFR0) < 30mL/min or without information about the GFR 2-year post-surgery (GFR2) were excluded. Results: We included 725 patients, of whom 647 (89.2%) women, with 41 (IQR 34-51) years, a median weight of 112.4 (IQR 103.0-125.0) kg and a median BMI of 43.4 (IQR 40.6-46.9) kg/m2. Of these, 459 (63.3%) performed gastric bypass (RYGB), 144 (19.9%) placed an adjustable gastric band (AGB) and 122 (16.8%) underwent vertical gastrectomy (VG). At 2-year post-surgery, excess weight loss (EWL) was 60.1 (IQR 43.7-72.4) %. There was a significant improve of metabolic and inflammatory status, as well as a significant decrease in the proportion of patients with diabetes, arterial hypertension and dyslipidemia (p < 0.0001). At baseline, 38 (5.2%) of subjects had hyperfiltration with a GFR0 ≥ 125mL/min/1.73m2, 492 (67.9%) had a GFR0 90-124 mL/min/1.73m2, 178 (24.6%) had a GFR0 60-89 mL/min/1.73m2, and 17 (2.3%) had a GFR0 < 60 mL/min/1.73m2. GFR decreased in 63.2% of patients with hyperfiltration (ΔGFR=-2.5±7.6), and increased in 96.6% (ΔGFR=22.2±12.0) and 82.4% (ΔGFR=24.3±30.0) of the subjects with GFR0 60-89 and < 60 mL/min/1.73m2, respectively ( p < 0.0001). This trend was maintained when adjustment was made for the type of surgery performed. Of 321 patients, 10 (3.3%) had a urinary albumin excretion (UAE) > 300 mg/dL (A3), 44 (14.6%) had a UAE 30-300 mg/dL (A2) and 247 (82.1%) has a UAE < 30 mg/dL (A1). Albuminuria decreased after surgery and at 2-year follow-up only 1 (0.3%) patient had A3, 17 (5.6%) had A2 and 283 (94%) had A1 (p < 0,0001). In multivariate analysis, the variables independently associated with ΔGFR were BMI (positively) and fasting plasma glucose (negatively). During the 2-year follow-up, only 57 of the 725 patients had transient urinary excretion of calcium oxalate crystals. None has records of oxalate-mediated renal complications at our center. Conclusions: The evolution of GFR after BS seems to depend on the initial renal function, as it decreases in subjects with hyperfiltration, but tends to increase in those with renal dysfunction. Our results suggest that BS is associated with improvement of renal outcomes, without significant increase of renal complications. So, apart the clear benefits in metabolic and inflammatory status, maybe obese adults with nondialysis-dependent CKD should be referred for bariatric surgery evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=albuminuria" title="albuminuria">albuminuria</a>, <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title=" bariatric surgery"> bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=glomerular%20filtration%20rate" title=" glomerular filtration rate"> glomerular filtration rate</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20function" title=" renal function"> renal function</a> </p> <a href="https://publications.waset.org/abstracts/67680/analyzing-the-impact-of-bariatric-surgery-in-obesity-associated-chronic-kidney-disease-a-2-year-observational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67680.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">360</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">621</span> Evaluation of Methodologies for Measuring Harmonics and Inter-Harmonics in Photovoltaic Facilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=An%C3%A9sio%20de%20Leles%20Ferreira%20Filho">Anésio de Leles Ferreira Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Wesley%20Rodrigues%20de%20Oliveira"> Wesley Rodrigues de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%A9ssica%20Santoro%20Gon%C3%A7alves"> Jéssica Santoro Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Andr%C3%A9s%20Cormane%20Angarita"> Jorge Andrés Cormane Angarita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in electric power demand in face of environmental issues has intensified the participation of renewable energy sources such as photovoltaics, in the energy matrix of various countries.

In Brazil, the Resolution 306/04 of the National Health Surveillance Agency classifies the MW into 5 groups as follows: Group A (GA) biological, Group B (GB) chemical, Group C (GC) radioactive waste, Group D (GD) common, and Group E (GE) sharps. Objective: This study aimed to determine the amount of waste generated in hospitals of Ribeirão Preto, São Paulo, Brazil. Material and Methods: This is a field research, exploratory, using quantitative variables. The survey was conducted in 11 hospitals in Ribeirão Preto, located in the State of São Paulo, Brazil. It is noted that the study sample included general hospitals, skilled, university, maternity, and psychiatric; public, private, and philanthropic; and large, medium, and small. To quantify the MW, the weighing of the waste was held for six days, following methodology adapted from PAHO. Data were analyzed using descriptive statistics, determining the average global generation of MW and for each group. This research was carried out after approval by the Ethics in Research of the University of São Paulo. Thus, in order to comply with the ethical principles of research, to present the results hospitals were numbered from 1 to 11. Results: The data revealed a greater generation of biological waste among teaching hospitals, which can be justified by the use of materials for the realization of techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20health" title="environmental health">environmental health</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20of%20medical%20waste" title=" management of medical waste"> management of medical waste</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20waste" title=" medical waste"> medical waste</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/31194/generation-of-medical-waste-in-hospitals-in-interior-of-sao-paulo-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31194.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">369</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">619</span> Breast Cancer Mortality and Comorbidities in Portugal: A Predictive Model Built with Real World Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cec%C3%ADlia%20M.%20Ant%C3%A3o">Cecília M.

This retrospective observational study aimed at identifying comorbidities associated with BC female patients admitted to Portuguese public hospitals (2010-2018), investigating the effect of comorbidities on BC mortality rate, and building a predictive model using logistic regression. Results showed that the BC mortality in Portugal decreased in this period and reached 4.37% in 2018. Adjusted odds ratio indicated that secondary malignant neoplasms of liver, of bone and bone marrow, congestive heart failure, and diabetes were associated with an increased chance of dying from breast cancer. Although the Lisbon district (the most populated area) accounted for the largest percentage of BC patients, the logistic regression model showed that, besides patient’s age, being resident in Bragança, Castelo Branco, or Porto districts was directly associated with an increase of the mortality rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=comorbidities" title=" comorbidities"> comorbidities</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression" title=" logistic regression"> logistic regression</a>, <a href="https://publications.waset.org/abstracts/search?q=adjusted%20odds%20ratio" title=" adjusted odds ratio"> adjusted odds ratio</a> </p> <a href="https://publications.waset.org/abstracts/143667/breast-cancer-mortality-and-comorbidities-in-portugal-a-predictive-model-built-with-real-world-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</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">618</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">617</span> Growth of Algal Biomass in Laboratory and in Pilot-Scale Algal Photobioreactors in the Temperate Climate of Southern Ireland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linda%20A.%20O%E2%80%99Higgins">Linda A.

The effects of variable sunlight and culture density were deconvoluted by a mathematical model. The analysis showed that algal growth was light-limited due to shading by external construction elements and due to light attenuation within the algal bags. The model was also used to predict maximum biomass productivity. The manipulative experiments and the model predictions were confronted with data from a production season of a 10m2 pilot-scale photobioreactor, Phytobag (10,000 L). The analysis confirmed light limitation in all three photobioreactors. An additional limitation of biomass productivity was caused by the nitrogen starvation that was used to induce lipid accumulation. Reduction of shading and separation of biomass and lipid production are proposed for future optimization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgae" title="microalgae">microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=batch%20cultivation" title=" batch cultivation"> batch cultivation</a>, <a href="https://publications.waset.org/abstracts/search?q=Chlorella%20vulgaris" title=" Chlorella vulgaris"> Chlorella vulgaris</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathematical%20model" title=" Mathematical model"> Mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=photobioreactor" title=" photobioreactor"> photobioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=scale-up" title=" scale-up"> scale-up</a> </p> <a href="https://publications.waset.org/abstracts/168630/growth-of-algal-biomass-in-laboratory-and-in-pilot-scale-algal-photobioreactors-in-the-temperate-climate-of-southern-ireland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168630.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">116</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">616</span> Canine Neonatal Mortality at the São Paulo State University Veterinary Hospital, Botucatu, São Paulo, Brazil – Preliminary Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20L.%20G.%20Louren%C3%A7o">Maria L.

Data regarding canine neonatal mortality are scarce in Brazil. This study aims at describing the neonatal mortality rates in dogs, as well as the main causes of death. The study included 152 litters and 669 neonates admitted to the São Paulo State University (UNESP) Veterinary Hospital, Botucatu, São Paulo, Brazil between January 2018 and September 2019. The overall mortality rate was 16.7% (112/669), with 40% (61/152) of the litters presenting at least one case of stillbirth or neonatal mortality. The rate of stillbirths was 7.7% (51/669), while the neonatal mortality rate was 9% (61/669). The early mortality rate (0 to 2 days) was 13.7% (92/669), accounting for 82.1% (92/112) of all deaths. The late mortality rate (3 to 30 days) was 2.7% (18/669), accounting for 16% (18/112) of all deaths. Infection was the causa mortis in 51.8% (58/112) of the newborns, of which 30.3% (34/112) were caused by bacterial sepsis, and 21.4% (24/112) were caused by other bacterial, viral or parasite infections. Other causes of death included congenital malformations (15.2%, 17/112), of which 5.3% (6/112) happened through euthanasia due to malformations incompatible with life; asphyxia/hypoxia by dystocia (9.8%, 11/112); wasting syndrome in debilitated newborns (6.2%, 7/112); aspiration pneumonia (3.6%, 4/112); agalactia (2.7%, 3/112); trauma (1.8%, 2/112); administration of contraceptives to the mother (1.8%, 2/112) and unknown causes (7.1%, 8/112). The neonatal mortality rate was considered high, but they may be even higher in locations without adequate care for the mothers and neonates. Therefore, prenatal examinations and early neonatal care are of utmost importance for the survival of these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neonate%20dogs" title="neonate dogs">neonate dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=puppies" title=" puppies"> puppies</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality%20rate" title=" mortality rate"> mortality rate</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20death" title=" neonatal death"> neonatal death</a> </p> <a href="https://publications.waset.org/abstracts/117940/canine-neonatal-mortality-at-the-sao-paulo-state-university-veterinary-hospital-botucatu-sao-paulo-brazil-preliminary-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117940.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">615</span> Bowen Ratio in Western São Paulo State, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elaine%20Cristina%20Barboza">Elaine Cristina Barboza</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Jaschke%20Machado"> Antonio Jaschke Machado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses micrometeorological aspects of the urban climate in three cities in Western São Paulo State: Presidente Prudente, Assis, and Iepê.

The cultivation is based mainly on the following species: Hylocereus undatus, H. polyrhizus, H. setaceus and H. megalanthus, being H. undatus the most cultivated in Brazil. The pitahaya cultivation is recent in Brazil and is concentrated in São Paulo. Meloidogyne enterolobii is of unknown origin being distributed in several countries. This nematode has recently been detected in Brazil causing damage in several crops. Similarly, M. incognita is a widely distributed pathogen in Brazil. The objective of this study is to evaluate the following accesses of pitahaya to M. enterolobii: CPAC- Py H. hundatus 01, 02, 03, 04, 05, 06, 07 and 08; CPAC - Py H. costaricense 8A; CPAC - Py Selenicereus setaceus 17 and CPAC - Py S. megalantus 22. And the following accesses to M. incognita: CPAC- Py H. hundatus 05; CPAC - Py H. costaricense 8A; CPAC - Py S. setaceus 17 and CPAC - Py S. megalantus 22. According to the results, CPAC – Py H. hundatus 01, 02, 03, 04 and 07 were considered resistant. While CPAC - Py 05 and 08 was susceptible. CPAC-Py 06 also was considered susceptible, because there was the reaction of susceptibility in one of the trials. Given this wide diversity in H. hundatus and being this species the most cultivated in Brazil it is suggested to work more with this material in Embrapa Cerrados. CPAC - Py H. costaricense 8A behaved as susceptible in one of the trials. CPAC - Py S. setaceus 17 and CPAC – Py S. megalantus 22 were considered highly susceptible. The susceptibility of S. megalantus is widely described in the literature. In relation to M. incognita, there were differences between the results in both experiments, but all behaved as susceptible in at least one of the tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pitaya" title="pitaya">pitaya</a>, <a href="https://publications.waset.org/abstracts/search?q=meloidogyne" title=" meloidogyne"> meloidogyne</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit" title=" fruit"> fruit</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a> </p> <a href="https://publications.waset.org/abstracts/94504/host-status-of-pitaya-genotypes-fruit-to-meloidogyne-enterolobii-and-m-incognita" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94504.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">613</span> Hypercomplex Dynamics and Turbulent Flows in Sobolev and Besov Functional Spaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Romulo%20Damasclin%20Chaves%20dos%20Santos">Romulo Damasclin Chaves dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Henrique%20de%20Oliveira%20Sales"> Jorge Henrique de Oliveira Sales</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a rigorous study of advanced functional spaces, with a focus on Sobolev and Besov spaces, to investigate key aspects of fluid dynamics, including the regularity of solutions to the Navier-Stokes equations, hypercomplex bifurcations, and turbulence.

Additionally, the research delves into energy dissipation mechanisms in turbulent flows through the framework of Besov spaces. Key mathematical tools, such as interpolation theory, Littlewood-Paley decomposition, and energy cascade models, are integrated to develop a robust theoretical approach to these problems.

These hexavalent chromium compounds represent a risk to living beings and the environment, and, for this reason, there is a great need to investigate alternatives. Physical Vapor Deposition (PVD) is an environmentally friendly process that allows the deposition of wear and corrosion resistant thin films with excellent optical properties. However, PVD thin films are porous and if deposited onto low corrosion resistant substrates, lead to a degradation risk. The corrosion behavior of chromium-free electroplated coating systems finished with magnetron sputtered PVD thin films was investigated in this work. The electroplated systems consisted of distinct nickel layers deposited on top of a copper interlayer on acrylonitrile butadiene styrene (ABS) plates. Electrochemical and corrosion evaluation was conducted by electrochemical impedance spectroscopy and polarization curves on the different electroplated coating systems, with and without PVD thin film on top. The results show that the corrosion resistance is lower for the electroplated coating systems finished with PVD thin film for extended exposure periods when compared to those without the PVD overlay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PVD" title="PVD">PVD</a>, <a href="https://publications.waset.org/abstracts/search?q=electroplating" title=" electroplating"> electroplating</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a> </p> <a href="https://publications.waset.org/abstracts/153146/corrosion-behavior-of-different-electroplated-systems-coated-with-physical-vapor-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153146.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">611</span> A Genetic Algorithm Approach to Solve a Weaving Job Scheduling Problem, Aiming Tardiness Minimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Silva">Carolina Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Nuno%20Oliveira"> João Nuno Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Sousa"> Rui Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Paulo%20Silva"> João Paulo Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study uses genetic algorithms to solve a job scheduling problem in a weaving factory.

Besides, this study includes a high level of complexity once most of the real production constraints are applied, and several real data instances are tested. Topics such as data analyses and algorithm performance are addressed and tested, to offer a solution that can generate reliable and due date results. All the approaches will be tested in the operational environment, and the KPIs monitored, to understand the solution's impact on the production, with a particular focus on the total number of weeks of late deliveries to clients. Thus, the main goal of this research is to develop a solution that allows for the production of automatically optimized production plans, aiming to the tardiness minimizing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title="genetic algorithms">genetic algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20industry" title=" textile industry"> textile industry</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20scheduling" title=" job scheduling"> job scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/153173/a-genetic-algorithm-approach-to-solve-a-weaving-job-scheduling-problem-aiming-tardiness-minimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153173.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">157</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">610</span> The Desirable Construction of Urbanity in Spaces for Public Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giselly%20Barros%20Rodrigues">Giselly Barros Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Leite%20de%20Souza"> Carlos Leite de Souza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been a great discussion about urbanism, the right to the city, the search for the public space and the occupation and appropriation of people in the spaces of the city. This movement happens all over the world and also in the great Brazilian metropolises. The more human-friendly city - the desirable construction of urbanity - as well as the encouragement of walking or bicycling to the detriment of cars is one of the major issues addressed by urban planners and challenges in the process of reviewing regulatory frameworks. The fact is that even if there are public spaces or space for public use in private areas - it is essential that there be, besides a project focused on the people and the use of space, a good management not to generate excess of control and consequently the segregation between different ethnicities, classes or creed. With the insertion of the Strategic Master Plan of Sao Paulo (2014), there is great incentive for them to implement - in the private spaces - of mixed uses and active facades (Services and commerce in the basement of buildings), these incentives will generate a city for people in the medium and long term. This research seeks to discuss the extent to which these spaces are democratic, what their perceptions are in relation to the space of public use in private areas and why this perception may be the one that was originally idealized. For this study, we carried out bibliographic reviews where applied research were carried out in three case studies listed in Sao Paulo. Questionnaires were also applied to the actors who gave answers regarding their perceptions and how they were approached in the places analyzed. After analyzing the material, it was verified that in the three case studies analyzed, sitting on the floor is prohibited. In the two places in Paulista Avenue (Cetenco Plaza and Square of Mall Cidade Sao Paulo) there was no problem whatsoever in relation to the clothes or attitudes of the actors in the streets of Paulista Avenue in Sao Paulo city. Different from what happened in the Itaim neighborhood (Brascan Century Plaza), with more conservative characteristics, where the actors were heavily watched by security and observed by others due to their clothes and attitudes in that area. The city of Sao Paulo is slowly changing, people are increasingly looking for places of quality in public use in their daily lives. The Strategic Master Plan of Sao Paulo (2014) and the Legislation approved in 2016 envision a city more humane and people-oriented in the future. It is up to the private sector, the public, and society to work together so that this glimpse becomes an abundant reality in every city, generating quality of life and urbanity for all. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urbanity" title="urbanity">urbanity</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20for%20public%20use" title=" space for public use"> space for public use</a>, <a href="https://publications.waset.org/abstracts/search?q=appropriation%20of%20space" title=" appropriation of space"> appropriation of space</a>, <a href="https://publications.waset.org/abstracts/search?q=segregation" title=" segregation"> segregation</a> </p> <a href="https://publications.waset.org/abstracts/76085/the-desirable-construction-of-urbanity-in-spaces-for-public-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76085.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">237</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">609</span> Quality of Life of Health Professionals during the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elucir%20Gir">Elucir Gir</a>, <a href="https://publications.waset.org/abstracts/search?q=Myllena%20Nilce%20de%20Freitas%20Surmano"> Myllena Nilce de Freitas Surmano</a>, <a href="https://publications.waset.org/abstracts/search?q=Laelson%20Rochelle%20Milan%C3%AAs%20Sousa"> Laelson Rochelle Milanês Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Gon%C3%A7alves%20Menegueti"> Mayra Gonçalves Menegueti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cristina%20de%20Oliveira%20E%20Silva"> Ana Cristina de Oliveira E Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Karina%20Reis"> Renata Karina Reis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To analyze the factors associated with the worsening of the quality of life of health professionals in the Southeast region of Brazil during the COVID-19 pandemic and its associated factors. Method: Analytical cross-sectional study carried out with health professionals from the southeastern region of Brazil. Data collection took place through an online survey with a form stored on the Survey Monkey platform. Bivariate analysis was used, and the chi-square test was adopted, followed by the multiple binary logistic regression model based on the stepwise method. Results: 3,493 health professionals participated in the study. Factors associated with worsening quality of life were: Professional Category (Nursing assistant) [OR 1.851 (95%CI 1.035-3.311) p= 0.038]; types of people who provided care (people in general) [OR 1.445 (95%CI 1.072-1.945) p=0.015]; Supply of good quality PPE by the institution where he works (no) [OR 1.595 (CI 95% 1.144-2.223) p= 0.006] and Supply of good quality PPE by the institution where he works (in part) [OR 1.563 (CI 95% 1.257-1.943) p < 0.001]. Conclusion: The factors associated with the worsening of the quality of life of health professionals during the COVID-19 pandemic were: Professional Category (Nursing assistant); types of people who provided assistance (people in general); Supply of sufficient PPE by the institution where you work (no) and Supply of good quality PPE by the institution where you work (in part). Future studies should investigate to what extent QoL can be improved based on modifiable factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20professionals" title=" health professionals"> health professionals</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20infections" title=" respiratory infections"> respiratory infections</a> </p> <a href="https://publications.waset.org/abstracts/165013/quality-of-life-of-health-professionals-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165013.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">91</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">608</span> Study Biogas Produced by Strain Archaea Methanothrix soehngenii in Different Biodigesters UASB in Treating Brewery Effluent in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ederaldo%20Godoy%20Junior">Ederaldo Godoy Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20O.%20Jesus"> Ricardo O.

Four types of UASB digesters were studied made of different geometries and materials which are: a UASB IC steel 20 meters high; a circular UASB steel 6 meters high; an UASB reinforced concrete lined with geomembrane PEAB with 6 meters high; and finally a UASB plug flow comprising two UASB in serious rotomolded HDPE 6 meters high.Observed clearly that the biogas produced in the digester UASB steel H2S concentrations had values lower than the HDPE. With respect to efficiency in short time, the UASB IC showed the best results to absorb overloads, as the UASB circular steel showed an efficiency of 90% removal of the organic load. The UASB system plug flow in HDPE showed the lowest cost of deployment, and its efficiency in removing the organic load was 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=achaeas" title=" achaeas"> achaeas</a>, <a href="https://publications.waset.org/abstracts/search?q=UASB" title=" UASB"> UASB</a>, <a href="https://publications.waset.org/abstracts/search?q=Brewery%20effluent" title=" Brewery effluent"> Brewery effluent</a> </p> <a href="https://publications.waset.org/abstracts/43846/study-biogas-produced-by-strain-archaea-methanothrix-soehngenii-in-different-biodigesters-uasb-in-treating-brewery-effluent-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43846.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">357</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">607</span> Waste-based Porous Geopolymers to Regulate the Temperature and Humidity Fluctuations Inside Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joao%20A.%20Labrincha">Joao A.

This work reports the development of porous geopolymers or bi-layered composites, composed by a highly porous top-layer and a dense bottom-layer, showing high ability to reduce the temperature swings inside buildings and simultaneously buffer the humidity levels. The use of phase change materials (PCM) strongly reduces the indoor thermal fluctuation (up to 5 °C). The potential to modulate indoor humidity is demonstrated by the very high practical MBV (2.71 g/m2 Δ%HR). Since geopolymer matrixes are produced from wastes (biomass fly ash, red mud) the developed solutions contribute to sustainable and energy efficient and healthy building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste-based%20geopolymers" title="waste-based geopolymers">waste-based geopolymers</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20regulation" title=" temperature regulation"> temperature regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20buffer" title=" moisture buffer"> moisture buffer</a> </p> <a href="https://publications.waset.org/abstracts/177998/waste-based-porous-geopolymers-to-regulate-the-temperature-and-humidity-fluctuations-inside-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177998.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">61</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">606</span> Design of New Alloys from Al-Ti-Zn-Mg-Cu System by in situ Al3Ti Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joao%20Paulo%20De%20Oliveira%20Paschoal">Joao Paulo De Oliveira Paschoal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20Victor%20Rodrigues%20Dantas"> Andre Victor Rodrigues Dantas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Almeida%20Da%20Silva%20Fernandes"> Fernando Almeida Da Silva Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugenio%20Jose%20Zoqui"> Eugenio Jose Zoqui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the adoption of High Pressure Die Casting technologies for the production of automotive bodies by the famous Giga Castings, the technology of processing metal alloys in the semi-solid state (SSM) becomes interesting because it allows for higher product quality, such as lower porosity and shrinkage voids. However, the alloys currently processed are derived from the foundry industry and are based on the Al-Si-(Cu-Mg) system. High-strength alloys, such as those of the Al-Zn-Mg-Cu system, are not usually processed, but the benefits of using this system, which is susceptible to heat treatments, can be associated with the advantages obtained by processing in the semi-solid state, promoting new possibilities for production routes and improving product performance. The current work proposes a new range of alloys to be processed in the semi-solid state through the modification of aluminum alloys of the Al-Zn-Mg-Cu system by the in-situ formation of Al3Ti intermetallic. Such alloys presented the thermodynamic stability required for semi-solid processing, with a sensitivity below 0.03(Celsius degrees * -1), in a wide temperature range. Furthermore, these alloys presented high hardness after aging heat treatment, reaching 190HV. Therefore, they are excellent candidates for the manufacture of parts that require low levels of defects and high mechanical strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloys" title="aluminum alloys">aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=semisolid%20metals%20processing" title=" semisolid metals processing"> semisolid metals processing</a>, <a href="https://publications.waset.org/abstracts/search?q=intermetallics" title=" intermetallics"> intermetallics</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20aluminide" title=" titanium aluminide"> titanium aluminide</a> </p> <a href="https://publications.waset.org/abstracts/194660/design-of-new-alloys-from-al-ti-zn-mg-cu-system-by-in-situ-al3ti-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194660.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">13</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">605</span> Mathematical Modeling for the Break-Even Point Problem in a Non-homogeneous System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Filipe%20Cardoso%20de%20Oliveira">Filipe Cardoso de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lino%20Marcos%20da%20Silva"> Lino Marcos da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ademar%20Nogueira%20do%20Nascimento"> Ademar Nogueira do Nascimento</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristiano%20Hora%20de%20Oliveira%20Fontes"> Cristiano Hora de Oliveira Fontes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a mathematical formulation for the production Break-Even Point problem in a non-homogeneous system. The optimization problem aims to obtain the composition of the best product mix in a non-homogeneous industrial plant, with the lowest cost until the breakeven point is reached. The problem constraints represent real limitations of a generic non-homogeneous industrial plant for n different products. The proposed model is able to solve the equilibrium point problem simultaneously for all products, unlike the existing approaches that propose a resolution in a sequential way, considering each product in isolation and providing a sub-optimal solution to the problem. The results indicate that the product mix found through the proposed model has economical advantages over the traditional approach used. <p class="card-text"><strong>Keywords:</strong> <a
