In this study, the influence of fermentation and germination on the chemical properties of Lima bean (Phaseolus lunatus) flour were evaluated. The flours were analyzed for their proximate and mineral composition, using the standard assay methods. The result showed that fermentation and germination increased the moisture, protein and ash content of the flours while fiber, fat and carbohydrate were decreased. The protein level of fermented and germinated lima bean increased from 21.06–26.60%. The minerals: iron, copper, zinc, and phosphorous increased due to germination and fermentation. The phytate and tannin levels were drastically reduced in both the fermented and germinated flours. The result of this study revealed that fermentation and germination makes the nutrient in lima beans more accessible as it reduces the anti-nutrients. It is therefore recommended that lima bean be process accordingly for richer and more bio-availability of the nutrients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient" title="nutrient">nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-nutrient" title=" anti-nutrient"> anti-nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=fermented" title=" fermented"> fermented</a>, <a href="https://publications.waset.org/abstracts/search?q=germinated" title=" germinated"> germinated</a>, <a href="https://publications.waset.org/abstracts/search?q=lima%20bean%20flour" title=" lima bean flour "> lima bean flour </a> </p> <a href="https://publications.waset.org/abstracts/22168/the-effect-of-fermentation-and-germination-on-the-nutrient-and-antinutrient-composition-of-lima-bean-phaseolus-lunatus-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22168.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">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">150</span> Road Traffic Noise Mapping for Riyadh City Using GIS and Lima</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20A.%20Alsaif">Khalid A.

The use of PGPR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth. In the present study, strain improvement of PGPR isolates were carried out by chemical mutagenesis for the improvement of growth and yield of lima bean. Induced mutagenesis is widely used for the selection of microorganisms producing biologically active substances and further improving their activities. Strain improvement is usually done by classical mutagenesis which involves exposing the microbes to chemical or physical mutagens. The strains of Pseudomonas putida 4/1, Azotobacter chroococcum Р-29 and Bacillus subtilis were subjected to mutation process for strain improvement by treatment with a chemical agent (sodium nitrite) to cause mutation and were observed for its consequent action on the seeds germination and plant growth of lima bean (Phaseolus lunatus). Bacterial mutant strains of Pseudomonas putida M-1, Azotobacter chroococcum M-1 and Bacillus subtilis M-1, treated with sodium nitrite in the concentration of 5 mg/ml for 120 min, were found effective to enhance the germination of lima bean seeds compared to parent strains. Moreover, treatment of the lima bean seeds with a mutant strain of Bacillus subtilis M-1 had a significant stimulation effect on plant growth. The length of the stems and roots of lima bean treated with Bacillus subtilis M-1 increased significantly in comparison with parent strain in 1.6 and 1.3 times, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20mutagenesis" title="chemical mutagenesis">chemical mutagenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20bean" title=" kidney bean"> kidney bean</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20growth%20promoting%20rhizobacteria%20%28PGPR%29" title=" plant growth promoting rhizobacteria (PGPR)"> plant growth promoting rhizobacteria (PGPR)</a> </p> <a href="https://publications.waset.org/abstracts/100013/effect-of-chemical-mutagen-on-seeds-germination-of-lima-bean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100013.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">198</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">148</span> Multiannual Trends of Toxic and Potentially Toxic Microalgae (Ostreopsis cf. ovata, Prorocentrum lima, and Coolia monotis) in Sfax Coasts (North of Gabes Gulf, Tunisia)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moncer%20Malika">Moncer Malika</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Brahim%20Mounir"> Ben Brahim Mounir</a>, <a href="https://publications.waset.org/abstracts/search?q=Bel%20Hassen%20Malika"> Bel Hassen Malika</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Asma"> Hamza Asma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decades, microalgae communities have presented significant changes in their structure and taxa composition along the Mediterranean littoral shallow waters.

The objective of this research is to evaluate the effectiveness of the air-quality-WRF-Chem model with a horizontal resolution of 5 km x 5 km. For this purpose, the measurements of the hourly SO₂ and O₃ concentrations available in three air quality monitoring stations in Lima, Peru were used for the purpose of validating the simulations of the SO₂ and O₃ concentrations obtained with the WRF-Chem model in February 2018. For the quantitative evaluation of the simulations of these gases, statistical techniques were implemented, such as the average of the simulations; the average of the measurements; the Mean Bias (MeB); the Mean Error (MeE); and the Root Mean Square Error (RMSE). The results of these statistical metrics indicated that the simulated SO₂ and O₃ values over-predicted the SO₂ and O₃ measurements. For the SO₂ concentration, the MeB values varied from 0.58 to 26.35 µg/m³; the MeE values varied from 8.75 to 26.5 µg/m³; the RMSE values varied from 13.3 to 31.79 µg/m³; while for O₃ concentrations the statistical values of the MeB varied from 37.52 to 56.29 µg/m³; the MeE values varied from 37.54 to 56.70 µg/m³; the RMSE values varied from 43.05 to 69.56 µg/m³. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-ozone" title="ground-ozone">ground-ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=lima" title=" lima"> lima</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphur%20dioxide" title=" sulphur dioxide"> sulphur dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-chem" title=" WRF-chem"> WRF-chem</a> </p> <a href="https://publications.waset.org/abstracts/154756/evaluating-hourly-sulphur-dioxide-and-ground-ozone-simulated-with-the-air-quality-model-in-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154756.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">137</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">146</span> Mapping of Traffic Noise in Riyadh City-Saudi Arabia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20A.%20Alsaif">Khaled A.

The maps show that noise levels remain over 50 dBA and can exceed 70 dBA at the nearside of major roads and highways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=noise%20pollution" title="noise pollution">noise pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20traffic%20noise" title=" road traffic noise"> road traffic noise</a>, <a href="https://publications.waset.org/abstracts/search?q=LimA%20predictor" title=" LimA predictor"> LimA predictor</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a> </p> <a href="https://publications.waset.org/abstracts/36791/mapping-of-traffic-noise-in-riyadh-city-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36791.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">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">145</span> Aerosol Chemical Composition in Urban Sites: A Comparative Study of Lima and Medellin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20M.%20Pereira">Guilherme M.

The South American Emissions Megacities, and Climate project (SAEMC) has focused on the study of emissions and its influence on climate in the South American largest cities and it also included Lima (Peru) and Medellin (Colombia), sites where few studies of the genre were done. Lima is a coastal city with more than 8 million inhabitants and the second largest city in South America. Medellin is a 2.5 million inhabitants city and second largest city in Colombia; it is situated in a valley. The samples were collected in quartz fiber filters in high volume samplers (Hi-Vol), in 24 hours of sampling. The samples were collected in intensive campaigns in both sites, in July, 2010. Several species were determined in the aerosol samples of Lima and Medellin. Organic and elemental carbon (OC and EC) in thermal-optical analysis; biomass burning tracers (levoglucosan - Lev, mannosan - Man and galactosan - Gal) in high-performance anion exchange ion chromatography with mass spectrometer detection; water soluble ions in ion chromatography. The average particulate matter was similar for both campaigns, the PM10 concentrations were above the recommended by World Health Organization (50 µg m⁻³ – daily limit) in 40% of the samples in Medellin, while in Lima it was above that value in 15% of the samples. The average total ions concentration was higher in Lima (17450 ng m⁻³ in Lima and 3816 ng m⁻³ in Medellin) and the average concentrations of sodium and chloride were higher in this site, these species also had better correlations (Pearson’s coefficient = 0,63); suggesting a higher influence of marine aerosol in the site due its location in the coast. Sulphate concentrations were also much higher at Lima site; which may be explained by a higher influence of marine originated sulphate. However, the OC, EC and monosaccharides average concentrations were higher at Medellin site; this may be due to the lower dispersion of pollutants due to the site’s location and a larger influence of biomass burning sources. The levoglucosan average concentration was 95 ng m⁻³ for Medellin and 16 ng m⁻³ and OC was well correlated with levoglucosan (Pearson’s coefficient = 0,86) in Medellin; suggesting a higher influence of biomass burning over the organic aerosol in this site. The Lev/Man ratio is often related to the type of biomass burned and was close to 18, similar to the observed in previous studies done at biomass burning impacted sites in the Amazon region; backward trajectories also suggested the transport of aerosol from that region. Biomass burning appears to have a larger influence on the air quality in Medellin, in addition the vehicular emissions; while Lima showed a larger influence of marine aerosol during the study period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerosol%20transport" title="aerosol transport">aerosol transport</a>, <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20particulate%20matter" title=" atmospheric particulate matter"> atmospheric particulate matter</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20burning" title=" biomass burning"> biomass burning</a>, <a href="https://publications.waset.org/abstracts/search?q=SAEMC%20project" title=" SAEMC project"> SAEMC project</a> </p> <a href="https://publications.waset.org/abstracts/52007/aerosol-chemical-composition-in-urban-sites-a-comparative-study-of-lima-and-medellin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52007.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">263</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">144</span> Long Term Follow-Up, Clinical Outcomes and Quality of Life after Total Arterial Revascularisation versus Conventional Coronary Surgery: A Retrospective Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jitendra%20Jain">Jitendra Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Cassandra%20Hidajat"> Cassandra Hidajat</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansraj%20Riteesh%20Bookun"> Hansraj Riteesh Bookun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graft patency underpins long-term prognosis after coronary artery bypass grafting surgery (CABG). The benefits of the combined use of only the left internal mammary artery and radial artery, referred to as total arterial revascularisation (TAR), on long-term clinical outcomes and quality of life are relatively unknown. The aim of this study was to identify whether there were differences in long term clinical outcomes between recipients of TAR compared to a cohort of mostly arterial revascularization involving the left internal mammary, at least one radial artery and at least one saphenous vein graft. A retrospective analysis was performed on all patients who underwent TAR or were re-vascularized with supplementary saphenous vein graft from February 1996 to December 2004. Telephone surveys were conducted to obtain clinical outcome parameters including major adverse cardiac and cerebrovascular events (MACCE) and Short Form (SF-36v2) Health Survey responses. A total of 176 patients were successfully contacted to obtain postop follow up results. The mean follow-up length from time of surgery in our study was TAR 12.4±1.8 years and conventional 12.6±2.1. PCS score was TAR 45.9±8.8 vs LIMA/Rad/ SVG 44.9±9.2 (p=0.468) and MCS score was TAR 52.0±8.9 vs LIMA/Rad/SVG 52.5±9.3 (p=0.723).

The aim of this study was to explore the process of space appropriation that occurs in the Peripheral Library of the district El Agustino in Lima, Peru. Space appropriation is a process by which people develop a link with a place within a specific sociocultural context. This process has been related to positive outcomes, such as: participation and in the development of compassionate behaviors with these places. To achieve the purpose of the research, a qualitative design was selected because this will allowed exploring in deep the process in an specific context. The study interviewed six adults, all of whom were deliberately chosen to have the longest residence time in the district and also utilized the library the most. In a complementary manner, two children and one adolescent were interviewed. Likewise, two observations were made on a weekday and weekend, and public documentation information was collected. As a result, five categories linked to this process were identified. It was found that the process of space appropriation begins with the needs of the people who arrive at the library, which provides benefits to these people by fulfilling them. Next in the process, through the construction of meanings, the library is then valued as a pleasant, productive, safe and regulated place; as a result, people become identified with the library. The identification generated is subsequently reflected in the level of participation that the person has in the library, which may go in a continuum from no participating at all to a more direct involvement in the library activities, as well as voluntary and altruistic work. Finally, this process leads to the library becoming part of the neighborhood. This study allows having a better understanding of how sociospatial processes work in a Latinamerican context and in cities like Lima, where the third of the country’s population lives. Also, Lima has grown in the past 50 years in a excessively way and with lack of planification. Therefore, these results brings new research questions and highlights the importance of learning how to design public spaces in order to promote these processes to develop. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20with%20the%20place" title="bond with the place">bond with the place</a>, <a href="https://publications.waset.org/abstracts/search?q=place%20identity" title=" place identity"> place identity</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20spaces" title=" public spaces"> public spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20appropriation" title=" space appropriation"> space appropriation</a> </p> <a href="https://publications.waset.org/abstracts/86619/public-space-appropriation-of-a-public-peripheric-library-in-el-agustino-lima-metropolitana-a-qualitative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86619.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">142</span> From De Soto’s Solution to Urban Disaster: The Effects of Land Titling Policies on the Development of Cities of the Global South in the Case of Lima Peru </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jitka%20Molnarova">Jitka Molnarova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on De Soto’s idea that a formal land title can provide a secure home and access to credit to poor urban families, a large number of developing countries accepted the formalization of informal settlements as the ultimate solution for their housing crises and struggles with poverty. After two decades of implementation, very little is known about the effects this policy has on the quality of the neighborhoods it produces and on the development of cities in general. Using the capital of Peru -where the solution originated- as a case study, this paper illustrates the negative outcomes this policy has on urban development arguing that land titling encourages 1) expansion of the city often to areas of high physical risk, 2) production of precarious housing on unserviced land, and 3) practices of illegal land trafficking. The evidence is based on interviews with community leaders and officials working at the Cooperation for Formalization of Informal Property (COFOPRI), comparison of satellite images documenting the expansion of Lima in the past twenty years, and a technical evaluation of dozens of houses that have been or are in the process of being granted a land title. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COFOPRI" title="COFOPRI">COFOPRI</a>, <a href="https://publications.waset.org/abstracts/search?q=De%20Soto" title=" De Soto"> De Soto</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20policies" title=" housing policies"> housing policies</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20titling" title=" land titling"> land titling</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20trafficking" title=" land trafficking"> land trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=Lima" title=" Lima"> Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Peru" title=" Peru"> Peru</a>, <a href="https://publications.waset.org/abstracts/search?q=precarious%20housing" title=" precarious housing"> precarious housing</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20expansion" title=" urban expansion"> urban expansion</a> </p> <a href="https://publications.waset.org/abstracts/88211/from-de-sotos-solution-to-urban-disaster-the-effects-of-land-titling-policies-on-the-development-of-cities-of-the-global-south-in-the-case-of-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88211.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">187</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">141</span> Digital Transformation: The Effect of Artificial Intelligence on the Efficiency of Financial Administrative Workers in Peru in 2024</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Fabrizio%20Gavilano%20Farje">Thiago Fabrizio Gavilano Farje</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Patricio%20Herrera%20Malpartida"> Marcelo Patricio Herrera Malpartida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the influence of artificial intelligence (AI) on the work efficiency of administrative employees in the financial sector of Metropolitan Lima, Peru, during the year 2024. Focusing on the relationship between AI implementation and work efficiency, it addresses specific variables such as decision-making, motivation, and employee productivity. To accomplish the analysis between AI and work efficiency within the financial sector of Metropolitan Lima, it is necessary to evaluate how AI optimizes time in administrative tasks, examine how AI impacts the agility of the process of making decisions, and investigate the influence of AI on the satisfaction and motivation of employees. The research adopts a correlational and explanatory approach, designed to establish and understand the connections between AI and work efficiency. A survey design adapted from an OECD study is used, applying questionnaires to a representative sample of administrative workers in the financial sector who incorporate AI into their functions. The target population includes administrative workers in the financial sector of Metropolitan Lima, estimated at 73,097 employees based on data from the Censo Nacional de Empresas y Establecimientos and studies by the BCRP.

This strategy relies on the assumption that the community is aware that a persistent cough is a possible symptom of TB and that formal health care needs to be sought. Despite its importance, health knowledge specific to TB is underexplored in Peru. This study aimed to assess health literacy and level of TB knowledge among outpatients attending a referral hospital in Lima, Peru. The goal was to ascertain knowledge gaps in key areas relating to TB, to identify and prioritize subgroups for intervention, and to provide insight for policy and community interventions considering health literacy. Methods: An observational cross-sectional study was conducted using a survey to measure sociodemographic factors, tuberculosis knowledge, and health literacy. Bivariate and Multivariate logistic regression was performed to study the associations between variables and to account for potential confounders. The study was conducted at Hospital Cayetano Heredia in Lima, Peru from June – August 2017. Results: 272 participants were included in the analysis. 57.7% knew someone who had had TB before, 9% had had TB in the past. Two weeks a cough was correctly identified as a symptom that could be TB by 69.1%. High TB knowledge was found among 149 (54.8%) participants. High health literacy was found among 193 (71.0%) participants. Health literacy and TB knowledge were not significantly associated (OR 0.9 (95%CI 0.5-1.5)). After controlling for sex, age, district, education, health insurance, frequency of hospital visits and previous TB diagnosis: High TB knowledge was associated with knowing someone with TB (aOR 2.7 (95%CI 1.6-4.7)) and being a public transport driver, (aOR 0.2 (95%CI 0.05-0.9)). Not being poor was the single factor associated with high health literacy (aOR 3.8 (95%CI 1.6-8.9)). Conclusions: TB knowledge was fair, though 30% did not know the most important symptom of TB. Tailoring educational strategies to risk groups may enhance passive case detection especially amongst transport workers in Lima, Peru. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20literacy" title="health literacy">health literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=Peru" title=" Peru"> Peru</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis%20knowledge" title=" tuberculosis knowledge"> tuberculosis knowledge</a> </p> <a href="https://publications.waset.org/abstracts/89351/health-literacy-and-knowledge-related-to-tuberculosis-among-outpatients-at-a-referral-hospital-in-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89351.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">505</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">139</span> Complimentary Allusions: Shawl Scenes in Rossellini, Lean, Fellini, Kubrick, and Bertolucci Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Misha%20Nedeljkovich">Misha Nedeljkovich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the film’s famous scene (Roma città aperta-1945), Pina (Anna Magnani) collapses in the street when machined-gunned by a German soldier. Her son Marcello (Vito Annchiarico) tries to revive her. Her death is signaling not closure, but the cycle of life; Marcello saves Francesco with the shawl taken from his mother’s corpse. One pivotal scene in Brief Encounter (1945) occurs in the apartment of Alec’s (Trevor Howard) friend Stephen (Valentine Dyall), when Stephen returns to catch Alec and Laura (Celia Johnson) together alone. David Lean directs this scene using her shawl as a sign of in flagrante delicto. In La Strada (1954), Gelsomina (Giulietta Masina) was waving good bye when her mother sensing impending doom changed her mind and desperately tried to stop her waving back with her shawl: Don’t go my daughter! Your shawl! Your shawl! Gelsomina refuses to return, waving back: It’s time to go! Stanley Kubrick’s tale of a boxer who crosses a mobster to win the heart of a lady, Killer’s Kiss (1955), reminds us that Times Square used to contain sweaty boxing gyms and dance halls. The film’s longest Times Square interlude is its oddest: the boxer Davie Gordon played by Jamie Smith has his shawl stolen by two playful men in Shriners’ hats who are silent except for one who blows a harmonica, faintly heard over honking cabs and overheard conversations. This long sequence appears to be joining in on directors’ shawl conversations with Kubrick’s own twist. Principle characters will never know why all this happened to them that evening. Love, death, happiness and everlasting misery all of that is caused by Dave’s shawl. Finally, the decade of cinematic shawl conversations conclude in Betolucci’s Before the Revolution (Prima della rivoluzione–1964). One of his character’s lifts up a shawl asking if this was a Rossellini’s shawl. I argue that exploring complimentary allusions in a film where directors are acknowledging their own great debt to another film or filmmaker will further our knowledge of film history adding both depth and resonance to the great works in cinema. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allusions" title="allusions">allusions</a>, <a href="https://publications.waset.org/abstracts/search?q=Bertolucci" title=" Bertolucci"> Bertolucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Fellini" title=" Fellini"> Fellini</a>, <a href="https://publications.waset.org/abstracts/search?q=homage" title=" homage"> homage</a>, <a href="https://publications.waset.org/abstracts/search?q=Kubrick" title=" Kubrick"> Kubrick</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=Rossellini" title=" Rossellini"> Rossellini</a> </p> <a href="https://publications.waset.org/abstracts/20901/complimentary-allusions-shawl-scenes-in-rossellini-lean-fellini-kubrick-and-bertolucci-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20901.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">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> Use of Residues from Water Treatment and Porcelain Coatings Industry for Producing Eco-Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Araujo">Flavio Araujo</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiolla%20Lima"> Fabiolla Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Lima"> Julio Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Scalize"> Paulo Scalize</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Albuquerque"> Antonio Albuquerque</a>, <a href="https://publications.waset.org/abstracts/search?q=Heitor%20Reis"> Heitor Reis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the great environmental problems in the management of water treatment (WTP) is on the disposal of waste generated during the treatment process.

Thus, with the purpose to identify an environmentally sustainable disposal, residues were used to replace part of the soil, for production soil-cement bricks. It was used the residues from WTP and coatings industry Cecrisa (Brazil). Consequently, a greater amount of fine aggregate in the two samples of residues was found. The residue affects the quality of bricks produced, compared to the sample without residues. However, the results of compression and water absorption tests were obtained values that meet the standards, respectively 2.0 MPa and 20% absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20treatment%20residue" title="water treatment residue">water treatment residue</a>, <a href="https://publications.waset.org/abstracts/search?q=porcelain%20tile%20residue" title=" porcelain tile residue"> porcelain tile residue</a>, <a href="https://publications.waset.org/abstracts/search?q=WTP" title=" WTP"> WTP</a>, <a href="https://publications.waset.org/abstracts/search?q=brick" title=" brick"> brick</a> </p> <a href="https://publications.waset.org/abstracts/18184/use-of-residues-from-water-treatment-and-porcelain-coatings-industry-for-producing-eco-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18184.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">483</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">137</span> Preliminary Treatment in Wastewater Treatment Plants: Operation and Maintenance Aspects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priscila%20M.%20Lima">Priscila M.

Operation was done on 11.03.14. The The Left Internal Mammary Artery (LIMA) and the Right Internal Mammary Artery (RIMA) were harvested in skeletonized manner. The free RIMA was then anastomosed with LIMA to make LIMA-RIMA Y. Cardio Pulmonary Bypass was then established and coronary artery bypass grafts performed. LIMA was anastomosed to the Left Anterior Descending artery. RIMA was anastomosed to Posterior Descending Artery, 1st and 2nd Obtuse Marginal arteries in a sequential manner. Abdomen was opened by midline incision. The infrarenal aorta exposed and was found to be severely diseased. A Vascular Clamp was applied infrarenally, aortotomy done and limited endarterectomy performed. An end-to-side anastomosis was done with upper end of PTFE synthetic Y-graft (14/7 mm) to the infarenal Aorta and the Clamp released. Good flow noted in both limbs of the graft. Patient was then slowly weaned off from Cardio Pulmonary Bypass without difficulty. The distal two limbs of the Y graft were passed to the groin through retroperitoneal tunnels and anastomosed end-to-side with the common femoral arteries. Saphenous vein was interposed between common femoral and popliteal arteries bilaterally through subfascial tunnels in both thigh. On 12th postoperative day he was discharged from hospital in good general condition. Follow up after 3 months of operation the patient is doing good and free of chest pain and claudication pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20arterial" title="total arterial">total arterial</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20revascularization" title=" coronary revascularization"> coronary revascularization</a>, <a href="https://publications.waset.org/abstracts/search?q=aorto-bifemoral%20bypass" title=" aorto-bifemoral bypass"> aorto-bifemoral bypass</a>, <a href="https://publications.waset.org/abstracts/search?q=bifemoro-bipopliteal%20bypass" title=" bifemoro-bipopliteal bypass"> bifemoro-bipopliteal bypass</a> </p> <a href="https://publications.waset.org/abstracts/12890/total-arterial-coronary-revascularization-with-aorto-bifemoral-bipopliteal-bypass-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12890.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">472</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">135</span> Exploring Pisa Monuments Using Mobile Augmented Reality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihai%20Duguleana">Mihai Duguleana</a>, <a href="https://publications.waset.org/abstracts/search?q=Florin%20Girbacia"> Florin Girbacia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Postelnicu"> Cristian Postelnicu</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaello%20Brodi"> Raffaello Brodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Carrozzino"> Marcello Carrozzino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Augmented Reality (AR) has taken a big leap with the introduction of mobile applications which co-locate bi-dimensional (e.g. photo, video, text) and tridimensional information with the location of the user enriching his/her experience.

We propose a location-based AR application which combines co-location with the augmented visual information about Pisa monuments to establish a friendly navigation in this historic city. AR was used to render contextual visual information in the outdoor environment. The developed Android-based application offers two different options: it provides the ability to identify the monuments positioned close to the user’s position and it offers location information for getting near the key touristic objectives. We present the process of creating the monuments’ 3D map database and the navigation algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title="augmented reality">augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20compass" title=" electronic compass"> electronic compass</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=location-based%20service" title=" location-based service"> location-based service</a> </p> <a href="https://publications.waset.org/abstracts/54319/exploring-pisa-monuments-using-mobile-augmented-reality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54319.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">285</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">134</span> The Sound of Getting Closer: A Phenomenological Research of the Senses of Proximity and Touch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Lussana">Marcello Lussana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Closer is a wireless system developed by the “Design Research Lab” of the UdK Berlin that is able to detect the proximity and touch between two (or more) persons. We have been using this system for one performance and one installation: in both cases, the proximity and touch events of the two participants have been sonified using the software Supercollider. In this paper, we are going to focus on the actual experience of the participants involved, especially related to the awareness of their body, their level of proprioception and how they felt in their body and in connection with the other person. In order to give value to the lived experience of the participant, a phenomenological method described and developed by Professor Claire Petitmengin has been used. This strategy allowed the interviewees to become aware of their subjective experience, and describe it with great precision. This is essential in order to understand the actual state of consciousness of the users. Our aim is to research the senses of proprioception, touch, and proximity: as they all involve a pre-reflective state of consciousness, they are central for the understanding of human perception. The interviews revealed how this experience could improve and increase proprioception and awareness of your body. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interactive%20sound" title="interactive sound">interactive sound</a>, <a href="https://publications.waset.org/abstracts/search?q=phenomenology" title=" phenomenology"> phenomenology</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-reflective" title=" pre-reflective"> pre-reflective</a>, <a href="https://publications.waset.org/abstracts/search?q=proprioception" title=" proprioception"> proprioception</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20experience" title=" subjective experience"> subjective experience</a> </p> <a href="https://publications.waset.org/abstracts/60663/the-sound-of-getting-closer-a-phenomenological-research-of-the-senses-of-proximity-and-touch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60663.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">246</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">133</span> Role of GM1 in the Interaction between Amyloid Prefibrillar Oligomers of Salmon Calcitonin and Model Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristiano%20Giordani">Cristiano Giordani</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Diociaiuti"> Marco Diociaiuti</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Bombelli"> Cecilia Bombelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Zanetti-Polzi"> Laura Zanetti-Polzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Belfiore"> Marcello Belfiore</a>, <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Fioravanti"> Raoul Fioravanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianfranco%20Macchia"> Gianfranco Macchia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigated induced functional effects by evaluating Ca2+-influx in liposomes and cell viability in HT22-DIFF neurons. Only solutions rich in unstructured Prefibrillar-Oligomers (PFOs) were able, in the presence of Monosialoganglioside-GM1 (GM1), to induce Ca2+-influx and were also neurotoxic, suggesting a correlation between the two phenomena. Thus, in the presence of GM1, we investigated the protein conformation and liposome modification due to the interaction. Circular Dichroism showed that GM1 fostered the formation of β-structures and Energy Filtered-Transmission Electron Microscopy that PFOs formed “amyloid-channels” as reported for Aβ. We speculate that electrostatic forces occurring between the positive PFOs and negative GM1 drive the initial binding, while the hydrophobic profile of the flexible PFO is responsible for the subsequent pore formation. Conversely, the rigid β-structured mature/fibers (MFs) and proto-fibers (PFs) were unable to induce membrane damage and Ca2+- influx. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloid%20proteins" title="amyloid proteins">amyloid proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=neurotoxicity" title=" neurotoxicity"> neurotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid-rafts" title=" lipid-rafts"> lipid-rafts</a>, <a href="https://publications.waset.org/abstracts/search?q=GM1" title=" GM1"> GM1</a> </p> <a href="https://publications.waset.org/abstracts/118119/role-of-gm1-in-the-interaction-between-amyloid-prefibrillar-oligomers-of-salmon-calcitonin-and-model-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118119.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">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">132</span> A Gastro-Intestinal Model for a Rational Design of in vitro Systems to Study Drugs Bioavailability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pompa%20Marcello">Pompa Marcello</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauro%20Capocelli"> Mauro Capocelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincenzo%20Piemonte"> Vincenzo Piemonte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on a mathematical model able to describe the gastro-intestinal physiology and providing a rational tool for the design of an artificial gastro-intestinal system. This latter is mainly devoted to analyse the absorption and bioavailability of drugs and nutrients through in vitro tests in order to overcome (or, at least, to partially replace) in vivo trials. The provided model realizes a conjunction ring (with extended prediction capability) between in vivo tests and mechanical-laboratory models emulating the human body. On this basis, no empirical equations controlling the gastric emptying are implemented in this model as frequent in the cited literature and all the sub-unit and the related system of equations are physiologically based. More in detail, the model structure consists of six compartments (stomach, duodenum, jejunum, ileum, colon and blood) interconnected through pipes and valves. Paracetamol, Ketoprofen, Irbesartan and Ketoconazole are considered and analysed in this work as reference drugs. The mathematical model has been validated against in vivo literature data. Results obtained show a very good model reliability and highlight the possibility to realize tailored simulations for different couples patient-drug, including food adsorption dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gastro-intestinal%20model" title="gastro-intestinal model">gastro-intestinal model</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs%20bioavailability" title=" drugs bioavailability"> drugs bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=paracetamol" title=" paracetamol"> paracetamol</a>, <a href="https://publications.waset.org/abstracts/search?q=ketoprofen" title=" ketoprofen"> ketoprofen</a> </p> <a href="https://publications.waset.org/abstracts/92839/a-gastro-intestinal-model-for-a-rational-design-of-in-vitro-systems-to-study-drugs-bioavailability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92839.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">168</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">131</span> Safety and Maternal Anxiety in Mother's and Baby's Sleep: Cross-sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rayanne%20Branco%20Dos%20Santos%20Lima">Rayanne Branco Dos Santos Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Pinheiro%20Barbosa"> Lorena Pinheiro Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Ferreira%20Lima"> Kamila Ferreira Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Manuel%20Tegoma%20Ruiz"> Victor Manuel Tegoma Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Monyka%20Brito%20Lima%20Dos%20Santos"> Monyka Brito Lima Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Wendiane%20Gueiros%20Gaspar"> Maria Wendiane Gueiros Gaspar</a>, <a href="https://publications.waset.org/abstracts/search?q=Luzia%20Camila%20Coelho%20Ferreira"> Luzia Camila Coelho Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Cardozo%20Dos%20Santos%20Brito"> Leandro Cardozo Dos Santos Brito</a>, <a href="https://publications.waset.org/abstracts/search?q=Deyse%20Maria%20Alves%20Rocha"> Deyse Maria Alves Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The lack of regulation of the baby's sleep-wake pattern in the first years of life affects the health of thousands of women. Maternal sleep deprivation can trigger or aggravate psychosomatic problems such as depression, anxiety and stress that can directly influence maternal safety, with consequences for the baby's and mother's sleep. Such conditions can affect the family's quality of life and child development. Objective: To correlate maternal security with maternal state anxiety scores and the mother's and baby's total sleep time. Method: Cross-sectional study carried out with 96 mothers of babies aged 10 to 24 months, accompanied by nursing professionals linked to a Federal University in Northeast Brazil. Study variables were maternal security, maternal state anxiety scores, infant latency and sleep time, and total nocturnal sleep time of mother and infant. Maternal safety was calculated using a four-point Likert scale (1=not at all safe, 2=somewhat safe, 3=very safe, 4=completely safe). Maternal anxiety was measured by State-Trait Anxiety Inventory, state-anxiety subscale whose scores vary from 20 to 80 points, and the higher the score, the higher the anxiety levels. Scores below 33 are considered mild; from 33 to 49, moderate and above 49, high. As for the total nocturnal sleep time, values between 7-9 hours of sleep were considered adequate for mothers, and values between 9-12 hours for the baby, according to the guidelines of the National Sleep Foundation. For the sleep latency time, a time equal to or less than 20 min was considered adequate. It is noteworthy that the latency time and the time of night sleep of the mother and the baby were obtained by the mother's subjective report. To correlate the data, Spearman's correlation was used in the statistical package R version 3.6.3. Results: 96 women and babies participated, aged 22 to 38 years (mean 30.8) and 10 to 24 months (mean 14.7), respectively. The average of maternal security was 2.89 (unsafe); Mean maternal state anxiety scores were 43.75 (moderate anxiety). The babies' average sleep latency time was 39.6 min (>20 min). The mean sleep times of the mother and baby were, respectively, 6h and 42min and 8h and 19min, both less than the recommended nocturnal sleep time. Maternal security was positively correlated with maternal state anxiety scores (rh=266, p=0.009) and negatively correlated with infant sleep latency (rh= -0.30. P=0.003). Baby sleep time was positively correlated with maternal sleep time. (rh 0.46, p<0.001). Conclusion: The more secure the mothers considered themselves, the higher the anxiety scores and the shorter the baby's sleep latency. Also, the longer the baby sleeps, the longer the mother sleeps. Thus, interventions are needed to promote the quality and efficiency of sleep for both mother and baby. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep" title="sleep">sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=mother-child%20relations" title=" mother-child relations"> mother-child relations</a> </p> <a href="https://publications.waset.org/abstracts/167836/safety-and-maternal-anxiety-in-mothers-and-babys-sleep-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Exergy Analysis of a Green Dimethyl Ether Production Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcello%20De%20Falco">Marcello De Falco</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianluca%20Natrella"> Gianluca Natrella</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauro%20Capocelli"> Mauro Capocelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO₂ capture and utilization (CCU) is a promising approach to reduce GHG(greenhouse gas) emissions. Many technologies in this field are recently attracting attention. However, since CO₂ is a very stable compound, its utilization as a reagent is energetic intensive. As a consequence, it is unclear whether CCU processes allow for a net reduction of environmental impacts from a life cycle perspective and whether these solutions are sustainable. Among the tools to apply for the quantification of the real environmental benefits of CCU technologies, exergy analysis is the most rigorous from a scientific point of view. The exergy of a system is the maximum obtainable work during a process that brings the system into equilibrium with its reference environment through a series of reversible processes in which the system can only interact with such an environment. In other words, exergy is an “opportunity for doing work” and, in real processes, it is destroyed by entropy generation. The exergy-based analysis is useful to evaluate the thermodynamic inefficiencies of processes, to understand and locate the main consumption of fuels or primary energy, to provide an instrument for comparison among different process configurations and to detect solutions to reduce the energy penalties of a process. In this work, the exergy analysis of a process for the production of Dimethyl Ether (DME) from green hydrogen generated through an electrolysis unit and pure CO₂ captured from flue gas is performed. The model simulates the behavior of all units composing the plant (electrolyzer, carbon capture section, DME synthesis reactor, purification step), with the scope to quantify the performance indices based on the II Law of Thermodynamics and to identify the entropy generation points. Then, a plant optimization strategy is proposed to maximize the exergy efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20DME%20production" title="green DME production">green DME production</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20analysis" title=" exergy analysis"> exergy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20penalties" title=" energy penalties"> energy penalties</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20efficiency" title=" exergy efficiency"> exergy efficiency</a> </p> <a href="https://publications.waset.org/abstracts/141731/exergy-analysis-of-a-green-dimethyl-ether-production-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141731.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">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">129</span> Non–Geometric Sensitivities Using the Adjoint Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Hayashi">Marcelo Hayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Lima"> João Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chieregatti"> Bruno Chieregatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernani%20Volpe"> Ernani Volpe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adjoint method has been used as a successful tool to obtain sensitivity gradients in aerodynamic design and optimisation for many years.

The procedure is then applied to the steady 2–D compressible Euler and incompressible Navier–Stokes flow equations.

Among the technologies investigated in the last decades, biomass gasification acquired great interest owing to the possibility of obtaining low-cost and CO₂ negative emission hydrogen production from a large variety of everywhere available organic wastes. Upstream and downstream treatment were then studied in order to maximize hydrogen yield, reduce the content of organic and inorganic contaminants under the admissible levels for the technologies which are coupled with, capture, and convert carbon dioxide. However, studies which analyse a whole process made of all those technologies are still missing. In order to fill this lack, the present paper investigated the coexistence of hydrothermal carbonization (HTC), sorption enhance gasification (SEG), hot gas cleaning (HGC), and CO₂ conversion by dielectric barrier discharge (DBD) plasma reactor for H₂ production from biomass waste by means of Aspen Plus software. The proposed model aimed to identify and optimise the performance of the plant by varying operating parameters (such as temperature, CaO/biomass ratio, separation efficiency, etc.). The carbon footprint of the global plant is 2.3 kg CO₂/kg H₂, lower than the latest limit value imposed by the European Commission to consider hydrogen as “clean”, that was set to 3 kg CO₂/kg H₂. The hydrogen yield referred to the whole plant is 250 gH₂/kgBIOMASS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20gasification" title="biomass gasification">biomass gasification</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=aspen%20plus" title=" aspen plus"> aspen plus</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption%20enhance%20gasification" title=" sorption enhance gasification"> sorption enhance gasification</a> </p> <a href="https://publications.waset.org/abstracts/164537/modelling-and-optimization-of-a-combined-sorption-enhanced-biomass-gasification-with-hydrothermal-carbonization-hot-gas-cleaning-and-dielectric-barrier-discharge-plasma-reactor-to-produce-pure-h2-and-methanol-synthesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164537.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">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> Proposal for a Model of Economic Integration for the Development of Industry in Cabinda, Angola</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20H.%20Bitebe">T.

Previous research has shown inconsistent results regarding the association between sleep patterns and body mass index (BMI), particularly among diverse populations such as Brazilian adults. Understanding these relationships is crucial for developing targeted interventions to address obesity and related health issues. Objective: This study aimed to investigate the association between sleep duration, insomnia, and BMI among Brazilian adults using data from a large national survey focused on chronic nutrition and sleep habits. Materials and Methods: The study included 2050 participants from a population-based virtual survey. BMI was calculated using self-reported weight and height measurements. Participants also reported usual bedtime and wake time on weekdays and weekends and whether they experienced symptoms of insomnia. The average sleep duration across the entire week was calculated as follows: [(5×sleep duration on weekdays) + (2×sleep duration on weekends)]/7. Linear regression analyses were conducted to assess the association between sleep duration, insomnia, and BMI, adjusting for potential confounding factors, including age, sex, marital status, physical exercise duration, and diet quality. Results: After adjusting for confounding variables, the study found that BMI decreased by 0.19 kg/m² for each additional hour of sleep duration (95% CI = -0.37, -0.02; P = 0.03). Conversely, individuals with insomnia had a higher BMI, with an increase of 0.75 kg/m² (95% CI = 0.28, 1.22; P = 0.002) compared to those without insomnia. Conclusions: The findings suggest a significant association between sleep duration, insomnia, and BMI among Brazilian adults. Longer sleep duration was associated with lower BMI, while insomnia was associated with higher BMI. These results underscore the importance of considering sleep patterns in strategies aimed at preventing and managing obesity in this population. Further research is needed to explore the underlying mechanisms and potential interventions targeting sleep-related factors to promote healthier body weight outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep" title="sleep">sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=chronobiology" title=" chronobiology"> chronobiology</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a> </p> <a href="https://publications.waset.org/abstracts/186449/association-of-sleep-duration-and-insomnia-with-body-mass-index-among-brazilian-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186449.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">44</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">125</span> Computational Tool for Surface Electromyography Analysis; an Easy Way for Non-Engineers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Araujo%20Soares">Fabiano Araujo Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Sauro%20Emerick%20Salomoni"> Sauro Emerick Salomoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Paulo%20Lima%20da%20Silva"> Joao Paulo Lima da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Luiz%20Moura"> Igor Luiz Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Adson%20Ferreira%20da%20Rocha"> Adson Ferreira da Rocha </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a tool developed in the Matlab platform.
