In this work the chemical structure of oleic acid chains was modified by homogeneous and heterogeneous catalysis in order to produce esters. The homogeneous epoxidation was carried out at H2O2 to oleic acid unsaturation molar ratio of 20:1. The reaction temperature was 338 K and reaction time 16 h. Formic acid was used as catalyst. For heterogeneous catalysis reaction temperature was 343 K and reaction time 24 h. The esters production was carried out by heterogeneous catalysis of the epoxidized oleic acid and butanol using Mg/SBA-15 as catalyst. The resulting products were confirmed by NMR (1H and 13C) and FTIR spectroscopy. The products were characterized before and after each reaction. The catalysts were characterized by X-ray diffraction, X-ray fluorescence, thermogravimetric analysis (TGA) and BET surface areas. The results were satisfactory for the bioproducts formed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acid%20oleic" title="acid oleic">acid oleic</a>, <a href="https://publications.waset.org/abstracts/search?q=bioproduct" title=" bioproduct"> bioproduct</a>, <a href="https://publications.waset.org/abstracts/search?q=esters" title=" esters"> esters</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxidation" title=" epoxidation"> epoxidation</a> </p> <a href="https://publications.waset.org/abstracts/51353/evaluation-of-esters-production-by-oleic-acid-epoxidation-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51353.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">356</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">114</span> Study of Coconut and Babassu Oils with High Acid Content and the Fatty Acids (C6 to C16) Obtained from These Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fl%C3%A1vio%20A.%20F.%20da%20Ponte">Fl谩vio A.

This work aims to the physicochemical evaluation of babassu oil (Orbinya speciosa) and coconut (Cocos nucifera) of low quality, as well the obtaining the free fatty acids 6 to 16 carbon atoms, with intention to be used as raw material for the biofuels production. The babassu oil and coconut low quality, as well the fatty acids obtained from these oils were characterized as their physicochemical properties and fatty acid composition (using gas chromatography coupled to mass). The NMR technique was used to assess the efficiency of fractional distillation under reduced pressure to obtain the intermediate carbonic chain fatty acids. The results showed that the bad quality in terms of physicochemical evaluation of babassu oils and coconut oils interfere directly in industrial application. However the fatty acids of intermediate carbonic chain (C6 to C16) may be used in cosmetic, pharmaceutical and particularly as the biokerosene fuel. The chromatographic analysis showed that the babassu oil and coconut oil have as major fatty acids are lauric acid (57.5 and 38.6%, respectively), whereas the top phase from distillation of coconut oil showed caprylic acid (39.1%) and major fatty acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=babassu%20oil%20%28Orbinya%20speciosa%29" title="babassu oil (Orbinya speciosa)">babassu oil (Orbinya speciosa)</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut%20oil%20%28Cocos%20nucifera%29" title=" coconut oil (Cocos nucifera)"> coconut oil (Cocos nucifera)</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a> </p> <a href="https://publications.waset.org/abstracts/48733/study-of-coconut-and-babassu-oils-with-high-acid-content-and-the-fatty-acids-c6-to-c16-obtained-from-these-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48733.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">320</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">113</span> Association of Gln223Arg Polymorphism of Gene LEPR, Levels of Leptin and Nourishing Habits in Mexican Adolescents with Morbid Obesity </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Patricia%20Beltran%20Miranda">Claudia Patricia Beltran Miranda</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B3nica%20L%C3%B3pez%20Anaya"> M贸nica L贸pez Anaya</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B3nica%20Navarro%20Meza"> M贸nica Navarro Meza</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Leonor%20Valderrama%20Chairez"> Maria Leonor Valderrama Chairez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mexico occupies the second world-wide place of morbid obese people (10- 12 million). Factors that predispose the development of MO are genetic, environmental, physiological, psycho-social and behavioral (nourishing habits). Objective: Associate Gln223Arg polymorphism of gene LEPR, levels of leptina and nourishing habits with the presence of morbid obesity in adolescents of the south of Jalisco (M茅xico). Methods: In 41 adolescents (18 normal weight and 23 morbid obesity) of 12 to 19 years of age, both sexes that were measure size and weight with tanita scale and stadimeter to determine IMC. Morbid obesity was determined by tables of the WHO and was established with a standard deviation >3. The Gln223Arg polymorphism have been identify by PCR and leptina levels by ELISA. Nourishing habits were evaluate by the questionnaire the Adolescent Food Habits Checklist. The statistical analysis was performed to compare mean scores obtained from the questionnaire when we compare morbid obesity vs. normal weight adolescents with p=0.03 and a significance of 95%. Results: frequencies alellics and genics were not stadistics significatives p= 0,011 and p=0,279 respectly when were compared between normal weight adolescents and morbib obesity Leptin levels and nourishing habits were associated with morbid obesity. The polymorphism not shown significance with morbid obesity. Conclusions: Dietary habits and leptin levels in adolescents are important factor that predisposes the development of obesity in adolescents. The presence of the polymorphism are not associated with morbid obesity in these subjects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leptin" title="leptin">leptin</a>, <a href="https://publications.waset.org/abstracts/search?q=nourishing%20habits" title=" nourishing habits"> nourishing habits</a>, <a href="https://publications.waset.org/abstracts/search?q=morbid%20obesity" title=" morbid obesity"> morbid obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a> </p> <a href="https://publications.waset.org/abstracts/28023/association-of-gln223arg-polymorphism-of-gene-lepr-levels-of-leptin-and-nourishing-habits-in-mexican-adolescents-with-morbid-obesity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28023.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">573</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">112</span> Virtualizing Attendance and Reducing Impacts on the Environment with a Mobile Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulo%20R.%20M.%20Andrade">Paulo R.

The Work Book tool was created using the framework of the Bologna declaration. The project concerns primarily pedagogy and design methodology, focusing on how we evaluate artistic work processes and projects and on how we can develop the preconditions for cross-disciplinary work. The original idea of the Work Book springs from the steady habit of the Swedish researcher and now retired full professor and dean Henriette Koblanck to put images, things and colours in a notebook, right from her childhood, writing down impressions and reflections. On this preliminary thought of making use of a work book, in a form freely chosen by the user, she began to develop the Design Program (Designprogrammet) that was applied at the Kalmar University now LNU Linnaeus University, where she called a number of professionals to collaborate, among them Monica Moro an Italian designer, researcher, and teacher in the field of colour and shape. The educational intention is that the Work Book should become a tool that is both inspirational for the process of thinking and intuitional creating, and personal support for both rational and technical thinking. The students were to use the Work Book not only to visually and graphically document their results from investigations, experiments and thoughts but also as a tool to present their works to others, -students, tutors and teachers, or to other stakeholders they discussed the proceedings with. To help the students a number of matrixes were developed oriented to evaluate the projects in elaboration, based on the Bologna Declaration. In conclusion, the feedback from the students is excellent; many are still using the Work Book as a professional tool as in their words they consider it a rather accurate representation of their working process, and furthermore of themselves, so much that many of them have used it as a portfolio when applying for jobs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20program" title="academic program">academic program</a>, <a href="https://publications.waset.org/abstracts/search?q=art" title=" art"> art</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment%20of%20student%E2%80%99s%20progress" title=" assessment of student鈥檚 progress"> assessment of student鈥檚 progress</a>, <a href="https://publications.waset.org/abstracts/search?q=Bologna%20Declaration" title=" Bologna Declaration"> Bologna Declaration</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assessment" title=" self-assessment"> self-assessment</a> </p> <a href="https://publications.waset.org/abstracts/63631/the-work-book-tool-a-lifelong-chronicle-part-of-the-designprogrammet-at-the-design-school-of-the-university-in-kalmar-sweden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63631.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">338</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">107</span> A Social-Environmental Way for Production of Building Materials with Solid Residues</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=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> </p> <p class="card-text"><strong>Abstract:</strong></p> Water treatment residues (WTR) are produced during water treatment and have recently been seen as a reusable material.

The process variables in heterogeneous catalysis were evaluated using an experimental design. Temperature and reaction time were the studied parameters, and the methyl esters content was the response of the experimental design. An ion exchange resin was used as a heterogeneous catalyst. The process optimization was carried out using response surface methodology (RSM) and polynomial model of second order. Results show that the most influential variables on the linear coefficient of each effect studied were temperature and reaction time. The best result of methyl esters conversion in the experimental design was under the conditions: 10% wt of catalyst; 100 掳C and 4 hours of reaction.

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.

The effluents generated by the water treatment industry need to be suitably processed for return to the environment or re-use. This article shows an alternative for the dehydration of sludge from the water treatment plants (WTP) and eventual disposal of sludge drained. Using the simple design methodology, we present a case study for a drainage in tanks geotextile, full-scale, which involve five sludge drainage tanks from WTP of the Rio Verde City. Aiming to the reutilization the water drained from the sludge and enabling its reuse both at the beginning of the treatment process at the WTP and in less noble services as for watering the gardens of the local town hall. The sludge will be used to production of building materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=re-use" title="re-use">re-use</a>, <a href="https://publications.waset.org/abstracts/search?q=residue" title=" residue"> residue</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment%20plants" title=" water treatment plants"> water treatment plants</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge" title=" sludge"> sludge</a> </p> <a href="https://publications.waset.org/abstracts/22217/dehydration-of-residues-from-wtp-for-application-in-building-materials-and-reuse-of-water-from-the-waste-treatment-a-feasible-solution-to-complete-treatment-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22217.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">490</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">98</span> Design of a Pulse Generator Based on a Programmable System-on-Chip (PSoC) for Ultrasonic Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Acevedo">Pedro Acevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20D%C3%ADaz"> Carlos D铆az</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B3nica%20V%C3%A1zquez"> M贸nica V谩zquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Joel%20Dur%C3%A1n"> Joel Dur谩n</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the design of a pulse generator based on the Programmable System-on-Chip (PSoC) module.

The theoretical framework makes use of a tight-binding model Hamiltonian, together with ab-initio calculations within quantum chemistry simulation. The alpha3 polypeptide is a 21-residue with three repeats of the seven-residue amino acid sequence Leu-Glu-Thr-Leu-Ala-Lys-Ala, forming an alpha鈥揾elical bundle structure. Its variants are obtained by Ala鈫扜ln substitution at the e (5th) and g (7th) position, respectively, of the alpha3 polypeptide amino acid sequence. Using transmission electron microscopy and atomic force microscopy, it was observed that the alpha3 polypeptide and one of its variant do have the ability to form fibrous assemblies, while the other does not. Our main aim is to investigate whether or not the biased alpha3 polypeptide and its variants can be also identified by quantum charge transport measurements through current-voltage (IxV) curves as a pattern to characterize their fibrous assemblies. It was observed that each peptide has a characteristic current pattern, which may be distinguished by charge transport measurements, suggesting that it might be a useful tool for the development of biosensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20transport%20properties" title="charge transport properties">charge transport properties</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20transmittance" title=" electronic transmittance"> electronic transmittance</a>, <a href="https://publications.waset.org/abstracts/search?q=current-voltage%20characteristics" title=" current-voltage characteristics"> current-voltage characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20sensor" title=" biological sensor"> biological sensor</a> </p> <a href="https://publications.waset.org/abstracts/46650/charge-transport-in-biological-molecules" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46650.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">665</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">96</span> Modelling Ibuprofen with Human Albumin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20L.%20Fulco">U.

Crystallographic data for the IBU鈥揌SA supramolecular complex shows that the ligand is confined to a large cavity at the subdomain IIIA and at the interface between the subdomains IIA and IIB, whose binding sites are FA3/FA4 and FA6, respectively. The interaction energy between the IBU molecule and each amino acid residue of these HSA binding pockets was calculated using the Molecular Fractionation with Conjugate Caps (MFCC) approach employing a dispersion corrected exchange鈥揷orrelation functional. Our investigation shows that the total interaction energy of IBU bound to HSA at binding sites of the fatty acids FA3/FA4 (FA6) converges only for a pocket radius of at least 8.5 掳A, mainly due to the action of residues Arg410, Lys414 and Ser489 (Lys351, Ser480 and Leu481) and residues in nonhydrophobic domains, namely Ile388, Phe395, Phe403, Leu407, Leu430, Val433, and Leu453 (Phe206, Ala210, Ala213, and Leu327), which is unusual. Our simulations are valuable for a better understanding of the binding mechanism of IBU to albumin and can lead to the rational design and the development of novel IBU-derived drugs with improved potency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ibuprofen" title="ibuprofen">ibuprofen</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20serum%20albumin" title=" human serum albumin"> human serum albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title=" density functional theory"> density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20energies" title=" binding energies"> binding energies</a> </p> <a href="https://publications.waset.org/abstracts/46649/modelling-ibuprofen-with-human-albumin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">95</span> An Architectural Model of Multi-Agent Systems for Student Evaluation in Collaborative Game Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monica%20Hoeldtke%20Pietruchinski">Monica Hoeldtke Pietruchinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Ricardo%20Pimentel"> Andrey Ricardo Pimentel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The teaching of computer programming for beginners has been presented to the community as a not simple or trivial task.

In public health, monitoring the health of primates is linked to the risk of transmission of zoonoses through scratches, bites and contact with biological samples. The project was approved by the Ethics Committee on the Use of Animals Protocol No. 170/2019. It was authorized by ICMBio Protocol No. 52117-1. The study was carried out in the period 2019-2022 in the municipality of An谩polis. Iron and galvanized wire traps were used and the animals were anesthetized with 4.4mg/kg zolethyl intramuscularly and saliva was collected through swabs. Fifty-three capuchin monkeys were captured from the Onofre Quinan Environmental Park in An谩polis-Goi谩s for health monitoring purposes. In the laboratory, the samples were deposited on the agar surface and seeded by exhaustion to obtain isolated colonies. These colonies were analyzed according to morphocolonial characteristics. Morphometric characterization and biochemical tests for bacterial identification were performed. A total of 861 bacterial samples were isolated, nine of which were strict anaerobic bacteria of the genus Peptostreptococcus. Previous and constant knowledge of the prevalence of pathogenic agents in biological samples is essential to be prepared to act in pandemic situations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazil" title="Brazil">Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a>, <a href="https://publications.waset.org/abstracts/search?q=monkeys" title=" monkeys"> monkeys</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/171380/health-monitoring-of-primates-in-a-conservation-unit-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171380.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">76</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">93</span> Health Post A Sustainable Prototype for the Third World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chizzoniti%20Domenico">Chizzoniti Domenico</a>, <a href="https://publications.waset.org/abstracts/search?q=Beggiora%20Klizia"> Beggiora Klizia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cattani%20Letizia"> Cattani Letizia</a>, <a href="https://publications.waset.org/abstracts/search?q=Moscatelli%20Monica"> Moscatelli Monica</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper concerns the study of sustainable construction materials applied on the "Health Post", a prototype for the primary health care situated in alienated areas of the world.

The idea is to create a Health Post with local construction materials that have a low environmental impact and promote the local workforce allowing reuse of traditional building techniques lowering production costs and transport. The aim of Primary Health Care Centre is to be a flexible and expandable structure identifying a modular form that can be repeated several times to expand its existing functions.

The first step was to define more precisely the information space. Second step was to identify how information space intersects the family space and institutional space educational levels represented by pre-school / school and pre-university (kindergarten, at elementary / middle school / high school). Interrelationship between the above-mentioned areas was another objective of the research. All these elements have been investigated through the original intention to identify how the information space can become an educational tool to support for the family space, education and institutional space. In addition, the aim of this research is to offer some solutions in this regard. Often the educational efforts appear to be blocked by the existence of this space. However, this paper demonstrates that Informational space can be an enemy of the educational system or be support systems if we know the internal structure and mechanisms.

Previous attempts to optimize the filtration process have employed mixed fibers as the filter medium in gas-solid separation. Some of the materials most frequently used this purpose are composed of polyester, polypropylene, and glass fibers. In order to improve the retention of cement particles in bag filters, the present study investigates the use of synthetic glass fiber filters and polypropylene fiber for particle filtration, with electrostatic discharge of 0 to -2 kV in cement particles. The filtration curves obtained showed that charging increased the particle collection efficiency and lowered the pressure drop. Particle diameter had a direct influence on the formation of the dust cake, and the application of electrostatic discharge to the particles resulted in the retention of more particles, hence increasing the lifetime of fabric filters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20fiber%20filter" title="glass fiber filter">glass fiber filter</a>, <a href="https://publications.waset.org/abstracts/search?q=particle" title=" particle"> particle</a>, <a href="https://publications.waset.org/abstracts/search?q=electrostatic%20discharge" title=" electrostatic discharge"> electrostatic discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=cement" title=" cement"> cement</a> </p> <a href="https://publications.waset.org/abstracts/58308/investigation-particle-behavior-in-gas-solid-filtration-with-electrostatic-discharge-in-a-hybrid-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58308.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">389</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">90</span> Analysis of Interleaving Scheme for Narrowband VoIP System under Pervasive Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monica%20Sharma">Monica Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Harjit%20Pal%20Singh"> Harjit Pal Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasbinder%20Singh"> Jasbinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Manju%20Bala"> Manju Bala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Voice over Internet Protocol (VoIP) system, the speech signal is degraded when passed through the network layers. The speech signal is processed through the best effort policy based IP network, which leads to the network degradations including delay, packet loss and jitter. The packet loss is the major issue of the degradation in the VoIP signal quality; even a single lost packet may generate audible distortion in the decoded speech signal. In addition to these network degradations, the quality of the speech signal is also affected by the environmental noises and coder distortions. The signal quality of the VoIP system is improved through the interleaving technique. The performance of the system is evaluated for various types of noises at different network conditions. The performance of the enhanced VoIP signal is evaluated using perceptual evaluation of speech quality (PESQ) measurement for narrow band signal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VoIP" title="VoIP">VoIP</a>, <a href="https://publications.waset.org/abstracts/search?q=interleaving" title=" interleaving"> interleaving</a>, <a href="https://publications.waset.org/abstracts/search?q=packet%20loss" title=" packet loss"> packet loss</a>, <a href="https://publications.waset.org/abstracts/search?q=packet%20size" title=" packet size"> packet size</a>, <a href="https://publications.waset.org/abstracts/search?q=background%20noise" title=" background noise "> background noise </a> </p> <a href="https://publications.waset.org/abstracts/14305/analysis-of-interleaving-scheme-for-narrowband-voip-system-under-pervasive-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14305.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">479</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">89</span> Customer Data Analysis Model Using Business Intelligence Tools in Telecommunication Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monica%20Lia">Monica Lia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a customer data analysis model using business intelligence tools for data modelling, transforming, data visualization and dynamic reports building.

Since the fruit is perishable, it requires conservation methods to prolong its shelf life. Mango cubes were dehydrated at 40掳C, 50掳C and 60掳C and by lyophilization, and the effect of these processes was investigated on the physicochemical characteristics (color and texture) of the products and monitoring of the main volatile compounds for the mango aroma. Volatile compounds were extracted by the SPME technique and analyzed in GC-MS system. Drying temperature at 60掳C and lyophilization showed higher efficiency in retention of main volatile compounds, being 63.93% and 60.32% of the total concentration present in the fresh pulp, respectively. The freeze-drying process also presented features closer to the fresh mango in relation to color and texture, which contributes to greater acceptability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mango" title="mango">mango</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze%20drying" title=" freeze drying"> freeze drying</a>, <a href="https://publications.waset.org/abstracts/search?q=convection%20drying" title=" convection drying"> convection drying</a>, <a href="https://publications.waset.org/abstracts/search?q=aroma" title=" aroma"> aroma</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/183064/physicochemical-characteristics-and-evaluation-of-main-volatile-compounds-of-fresh-and-dehydrated-mango" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183064.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">64</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">87</span> Evaluation of the Mechanical Behavior of a Retaining Wall Structure on a Weathered Soil through Probabilistic Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20V.%20S.%20Mascarenhas">P.

These kinds of engineering constructions may present instabilities over the time and may require reinforcement or even rebuilding of the structure. In this context, statistical analysis is an important tool for decision making regarding retaining structures. This study approaches the failure probability of the construction of a retaining wall over the debris of an old and collapsed one. The new solution’s extension length will be of approximately 350 m and will be located over the margins of the Lake Paranoá, Brasilia, in the capital of Brazil. The building process must also account for the utilization of the ruins as a caisson. A series of <em>in situ</em> and laboratory experiments defined local soil strength parameters. A Standard Penetration Test (SPT) defined the <em>in situ</em> soil stratigraphy. Also, the parameters obtained were verified using soil data from a collection of masters and doctoral works from the University of Brasília, which is similar to the local soil. Initial studies show that the concrete wall is the proper solution for this case, taking into account the technical, economic and deterministic analysis. On the other hand, in order to better analyze the statistical significance of the factor-of-safety factors obtained, a Monte Carlo analysis was performed for the concrete wall and two more initial solutions. A comparison between the statistical and risk results generated for the different solutions indicated that a Gabion solution would better fit the financial and technical feasibility of the project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economical%20analysis" title="economical analysis">economical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20failure" title=" probability of failure"> probability of failure</a>, <a href="https://publications.waset.org/abstracts/search?q=retaining%20walls" title=" retaining walls"> retaining walls</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/78642/evaluation-of-the-mechanical-behavior-of-a-retaining-wall-structure-on-a-weathered-soil-through-probabilistic-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78642.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">406</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">86</span> Geometry of the Bandaging Procedure and Its Application while Wrapping Bandages for Treatment of Leg Ulcers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monica%20Puri%20Sikka">Monica Puri Sikka</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrato%20Ghosh%20Arunangshu%20Mukhopadhyay"> Subrato Ghosh Arunangshu Mukhopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Appropriate compression bandaging is important for compression therapeutic medical diseases. The high compression approach employed for treating venous leg ulcers should be used correctly so that sufficient (but not excessive) pressure is applied. Bandages used to treat venous disease by compression should achieve and sustain effective levels and gradients of pressure and minimise the risk of pressure trauma. To maintain graduated compression on the limb the bandage needs to be applied at same tension for each layer from ankle to the knee. In this paper the geometry for various bandaging procedures is used to wrap each layer of bandage by marking the relaxed length of the bandage. The relaxed length is calculated depending on the stretch, average circumference of the limb on which it is to be applied and the bandaging technique to be used. This paper aims at developing a scientific approach while applying the bandage to reduce the inter operator variability in applying same tension on each successive layer of bandage. <p
