In this regard, this paper describes the woven self-reinforced PLA composites manufacturing processes: the commingling of yarns, weaving, and hot pressing and characterizes the manufactured laminates. Different structures and properties can be achieved by varying the hot compaction process parameters (pressure, holding time, and temperature). The specimens manufactured were characterized in terms of thermal properties (DSC), microstructure (C-scan optical microscope and SEM), strength (tensile test), and biocompatibility (MTT assays). Considering the final device, 155 ℃ for 10 min at 2 MPa act as the more appropriate hot pressing parameters. The laminate produced with these conditions has few voids/porosity, a tensile strength of 30.39 ± 1.21 MPa, and a modulus of 4.09 ± 0.24 GPa. Subsequently to the tensile testing was possible to observe fiber pullout from the fracture surfaces, confirming that this material behaves as a composite. From the results, no single laminate can fulfill all the requirements, being necessary to compromise in function of the priority property. Further investigation is required to improve materials' mechanical performance. Subsequently, process parameters and materials configuration can be adjusted depending on the place and type of implant to suit its function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=woven%20fabric" title="woven fabric">woven fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=self-reinforced%20polymer%20composite" title=" self-reinforced polymer composite"> self-reinforced polymer composite</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28lactic%20acid%29" title=" poly(lactic acid)"> poly(lactic acid)</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title=" biodegradable"> biodegradable</a> </p> <a href="https://publications.waset.org/abstracts/141844/manufacturing-and-characterization-of-bioresorbable-self-reinforced-pla-composites-for-bone-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141844.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">195</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">527</span> Math Rally Proposal for the Teaching-Learning of Algebra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liliana%20O.%20Mart%C3%ADnez">Liliana O.

This complicatedness may be responsible for the delivery of an overall poor experience to the learners, and it calls for a formal rating framework that takes into account the diverse aspects of an architecture for synchronous video e-learning systems.

In addition, they can be part of the composition of different types of products, including foods (functional foods), medicines, and dietary supplements. The objective of the present work was to evaluate the effect of the feeding of Holstein calves supplemented with bacillus subtilis PB6 in morbidity and mortality. 60 newborn animals were used, randomly included in 1 of 3 treatments. The treatments were as follows: T1 = control, T2 = 10 g / calf / day. The first takes within 20 min after birth, T3 = 10 g / calf/day. The first takes between 12 and 24 h after birth. In all the treatments, 432 L of pasteurized whole milk divided into two doses/day 07:00 and 15:00, respectively, were given for 60 days. The addition of bacillus subtilis PB6 was carried out in the milk tub at the time of feeding them. The first colostrum intake (2 L • intake) was given within 2 h after birth, after which they were given a second 6 h after the first one. The diseases registered to monitor the morbidity and mortality of the calves were: diarrhea and pneumonia. The registry was carried out from birth to 60 days of life. The parameter evaluated was food consumption. The variable statistical analysis was performed using analysis of variance, and comparison of means was performed using the Tukey test. The value of P < 0.05 was used to consider the statistical difference. The results of the present study in relation to the consumption of food show no statistical difference P < 0.05 between treatments (14,762, 11,698, and 12,403 kg of food average, respectively). Calves group to which they were not provided Bacillus subtilis PB6 obtained higher feed intake. The addition of Bacillus subtilis PB6 in feeding calves does not increase feed intake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feeding" title="feeding">feeding</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic "> probiotic </a> </p> <a href="https://publications.waset.org/abstracts/118983/effect-of-food-supplies-holstein-calves-supplemented-with-bacillus-subtilis-pb6-in-morbidity-and-mortality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118983.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">524</span> Towards the Inhibition Mechanism of Lysozyme Fibrillation by Hydrogen Sulfide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indra%20Gonzalez%20Ojeda">Indra Gonzalez Ojeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20Quinones"> Tatiana Quinones</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Rosario"> Manuel Rosario</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Lednev"> Igor Lednev</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Lopez%20Garriga"> Juan Lopez Garriga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amyloid fibrils are stable aggregates of misfolded protein associated with many neurodegenerative disorders. It has been shown that hydrogen sulfide (H2S), inhibits the fibrillation of lysozyme through the formation of trisulfide (S-S-S) bonds. However, the overall mechanism remains elusive. Here, the concentration dependence of H2S effect was investigated using Atomic force microscopy (AFM), non-resonance Raman spectroscopy, Deep-UV Raman spectroscopy and circular dichroism (CD). It was found that small spherical aggregates with trisulfide bonds and a unique secondary structure were formed instead of amyloid fibrils when adding concentrations of 25 mM and 50 mM of H2S. This could indicate that H2S might serve as a protecting agent for the protein. However, further characterization of these aggregates and their trisulfide bonds is needed to fully unravel the function H2S has on protein fibrillation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloid%20fibrils" title="amyloid fibrils">amyloid fibrils</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20sulfide" title=" hydrogen sulfide"> hydrogen sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20folding" title=" protein folding"> protein folding</a>, <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title=" raman spectroscopy"> raman spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/86031/towards-the-inhibition-mechanism-of-lysozyme-fibrillation-by-hydrogen-sulfide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86031.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">216</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">523</span> Microstructural and Magnetic Properties of Ni50Mn39Sn11 and Ni50Mn36Sn14 Heusler Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mst%20Nazmunnahar">Mst Nazmunnahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20del%20Val"> Juan del Val</a>, <a href="https://publications.waset.org/abstracts/search?q=Alena%20Vimmrova"> Alena Vimmrova</a>, <a href="https://publications.waset.org/abstracts/search?q=Blanca%20Hernando"> Blanca Hernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Julian%20Gonz%C3%A1lez"> Julian González</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report the microstructural and magnetic properties of Ni50Mn39Sn11 and Ni50Mn36Sn14 ribbon Heusler alloys. Experimental results were obtained by differential scanning calorymetry, X-ray diffraction and vibrating sample magnetometry techniques. The Ni-Mn-Sn system undergoes a martensitic structural transformation in a wide temperature range. For example, for Ni50Mn39Sn11 the start and finish temperatures of the martensitic and austenite phase transformation for ribbon alloy were Ms = 336K , Mf = 328K, As = 335K and Af = 343K whereas no structural transformation is observed for Ni50Mn36Sn14 alloys. Magnetic measurements show the typical ferromagnetic behavior with Curie temperature 207K at low applied field of 50 Oe. The complex behavior exhibited by these Heusler alloys should be ascribed to the strong coupling between magnetism and structure, being their magnetic behavior determined by the distance between Mn atoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=as-cast%20ribbon" title="as-cast ribbon">as-cast ribbon</a>, <a href="https://publications.waset.org/abstracts/search?q=Heusler%20alloys" title=" Heusler alloys"> Heusler alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20properties" title=" magnetic properties"> magnetic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20transformation" title=" structural transformation"> structural transformation</a> </p> <a href="https://publications.waset.org/abstracts/23193/microstructural-and-magnetic-properties-of-ni50mn39sn11-and-ni50mn36sn14-heusler-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23193.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">455</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">522</span> Analysis of Preferences in Decision Making in a Bilateral Negotiation Context: An Experimental Approach from Game Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20V.%20Gonzalez">Laura V.

The objective of this paper is to analyze the effect ‘amount of information’ and ‘number of options’, on the behavior of competitors under a bilateral negotiation context. For the above, it has been designed an experiment as a classroom game where they negotiate goods, under the condition that none of the players knows exactly the real value of the asset. The game is designed under the concept of zero-sum (non-cooperative game) and focuses on the fact that agents must anticipate the strategies of their opponent to improve their chances of winning in the negotiation. The empirical results show that, contrary to the traditional view of expected utility theory, players prefer to obtain low profits and losses, when faced with a higher expectation of losses, using sub-optimal strategies not in accordance with game theory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilateral%20negotiation" title="bilateral negotiation">bilateral negotiation</a>, <a href="https://publications.waset.org/abstracts/search?q=classroom%20game" title=" classroom game"> classroom game</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a> </p> <a href="https://publications.waset.org/abstracts/87095/analysis-of-preferences-in-decision-making-in-a-bilateral-negotiation-context-an-experimental-approach-from-game-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87095.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">521</span> Attitude of University Students in the Use of Artificial Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Merlo">Ricardo Merlo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Gonz%C3%A1lez"> María González</a>, <a href="https://publications.waset.org/abstracts/search?q=Zully%20Rivero"> Zully Rivero</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Gonz%C3%A1lez"> Laura González</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This exploratory work was to know the perception of the use of artificial intelligence (AI) that university students have during their passage through the classroom.

However, despite the benefits it offers, it can also be detrimental to those developing countries characterized by a wide digital divide. It is for this reason that the objective of this research was to identify and describe the main characteristics, benefits, and obstacles of the digital economy for Latin American countries. Through a bibliographic review, using the analytical-synthetic method in the period 1995-2021, it was determined that the digital economy could give way to structural changes, reduce inequality, and promote processes of social inclusion, as well as promote the construction and participatory development of organizational structures and institutional capacities in Latin American countries. However, the results showed that the digital economy is still incipient in the region and at least three factors are needed to establish it: joint work between academia, the business sector and the State, greater emphasis on learning and application of digital transformation and the creation of policies that encourage the creation of digital organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title="developing countries">developing countries</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20divide" title=" digital divide"> digital divide</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20economy" title=" digital economy"> digital economy</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20literacy" title=" digital literacy"> digital literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a> </p> <a href="https://publications.waset.org/abstracts/148398/digital-economy-as-an-alternative-for-post-pandemic-recovery-in-latin-america-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148398.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">140</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">518</span> Senior Management in Innovative Companies: An Approach from Creativity and Innovation Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Montalvo-Rodriguez">Juan Carlos Montalvo-Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Felipe%20Espinosa-Cristia"> Juan Felipe Espinosa-Cristia</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Islas%20Madariaga"> Pablo Islas Madariaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Cifuentes%20Valenzuela"> Jorge Cifuentes Valenzuela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents different relationships between top management and innovative companies, based on the developments of creativity and innovation management.

The objective of the study was to determine whether left atrial appendage occlusion (LAAO) could be a feasible option and benefit these patients. To this end, we studied the impact of LAAO plus antiplatelet drugs vs oral anticoagulants (OAC) (including direct OAC) plus antiplatelet drugs in these patients’ long-term outcomes. Methods: The results of 207 consecutive patients with NVAF who underwent coronary stenting were analyzed. A total of 146 patients were treated with OAC (75 with acenocoumarol, 71 with direct OAC) while 61 underwent LAAO. The median follow-up was 35 months. Patients also received antiplatelet therapy as prescribed by their cardiologist. The study received the proper ethical oversight. Results: Age (mean 75.7 years), and the past medical history of stroke were similar in both groups. However, the LAAO group had more unfavorable characteristics (history of coronary artery disease [CHA2DS2-VASc], and significant bleeding [BARC ≥ 2] and HAS-BLED). The occurrence of major adverse events (death, stroke/transient ischemic events, major bleeding) and major cardiovascular events (cardiac death, stroke/transient ischemic attack, and myocardial infarction) were significantly higher in the OAC group compared to the LAAO group: 19.75% vs 9.06% (HR, 2.18; P = .008) and 6.37% vs 1.91% (HR, 3.34; P = .037), respectively. Conclusions: In patients with NVAF undergoing coronary stenting, LAAO plus antiplatelet therapy produced better long-term outcomes compared to treatment with OAC plus antiplatelet therapy despite the unfavorable baseline characteristics of the LAAO group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stents" title="stents">stents</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title=" atrial fibrillation"> atrial fibrillation</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulants" title=" anticoagulants"> anticoagulants</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20atrial%20appendage%20occlusion" title=" left atrial appendage occlusion"> left atrial appendage occlusion</a> </p> <a href="https://publications.waset.org/abstracts/183786/left-atrial-appendage-occlusion-vs-oral-anticoagulants-in-atrial-fibrillation-and-coronary-stenting-the-desafio-registry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183786.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">68</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">516</span> Crossing Narrative Waters in World Cinema: Alamar (2009) and Kaili Blues (2015)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dustin%20Dill">Dustin Dill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physical movement of crossing over water points to both developing narrative tropes and innovative cinematography in World Cinema today. Two prime examples, Alamar (2009) by Pedro González-Rubio and Kaili Blues (2015) by Bi Gan, demonstrate how contemporary storytelling in a film not only rests upon these water shots but also emerges from them. The range of symbolism that these episodes in the story provoke goes hand in hand with the diverse filming sequences found in the respective productions. While González-Rubio decides to cut the scene into long and longer shots, Gan uses a single take. The differing angles depict equally unique directors and film projects: Alamar runs parallel to many definitions of the essay film, and Kaili Blues resonates much more with mystery and art film. Nonetheless, the crossing of water scenes influence the narratives’ subjects despite the generic consequences, and it is within the essay, mystery, and art film genres which allows for a better understanding of World Cinema. Tiago de Luca explains World Cinema’s prerogative of giving form to a certain type of spectator does not always line up. Given the immense number of interpretations of crossing water —the escape from suffering to find nirvana, rebirth, and colonization— underline the difficulty of categorizing it. If before this type of cross-genre was a trait that defined World Cinema in its beginning, this study observes that González-Rubio and Gan question the all-encompassing genre with their experimental shots of a universal narrative trope, the crossing of water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinematography" title="cinematography">cinematography</a>, <a href="https://publications.waset.org/abstracts/search?q=genre" title=" genre"> genre</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative" title=" narrative"> narrative</a>, <a href="https://publications.waset.org/abstracts/search?q=world%20cinema" title=" world cinema"> world cinema</a> </p> <a href="https://publications.waset.org/abstracts/89655/crossing-narrative-waters-in-world-cinema-alamar-2009-and-kaili-blues-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89655.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">292</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">515</span> Failure Analysis of Fuel Pressure Supply from an Aircraft Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Pilar%20Valles-gonzalez">M.

Multiple fracture cases of the fuel pressure control tube from aircraft engines have been reported. The studied set was composed of the mentioned tube, a welded connecting pipe, where the fracture has been produced, and a union nut. The fracture has been produced in one most critical zones of the tube, in a region next to the supporting body of the union nut to the connector. The tube material was X6CrNiTi18-10, an austenitic stainless steel. Chemical composition was determined using an X-Ray fluorescence spectrometer (XRF) and combustion equipment. Furthermore, the material has been mechanical, by hardness test, and microstructural characterized using a stereomicroscope and an optical microscope. The results confirmed that it is within specifications. To determine the macrofractographic features, a visual examination and a stereo microscope of the tube fracture surface have been carried out. The results revealed a tube plastic macrodeformation, surface damaged, and signs of a possible corrosion process. Fracture surface was also inspected by scanning electron microscopy (FE-SEM), equipped with a microanalysis system by X-ray dispersive energy (EDX), to determine the microfractographic features in order to find out the failure mechanism involved in the fracture. Fatigue striations, which are typical from a progressive fracture by a fatigue mechanism, have been observed. The origin of the fracture has been placed in defects located on the outer wall of the tube, leading to a final overload fracture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft%20engine" title="aircraft engine">aircraft engine</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=FE-SEM" title=" FE-SEM"> FE-SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=fractography" title=" fractography"> fractography</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20tube" title=" fuel tube"> fuel tube</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel" title=" stainless steel"> stainless steel</a> </p> <a href="https://publications.waset.org/abstracts/133219/failure-analysis-of-fuel-pressure-supply-from-an-aircraft-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133219.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">153</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">514</span> The Significance of Urban Space in Death Trilogy of Alejandro González Iñárritu</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Kaprzyk">Marta Kaprzyk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cinema of Alejandro González Iñárritu hasn’t been subjected to a lot of detailed analysis yet, what makes it an exceptionally interesting research material. The purpose of this presentation is to discuss the significance of urban space in three films of this Mexican director, that forms Death Trilogy: ‘Amores Perros’ (2000), ‘21 Grams’ (2003) and ‘Babel’ (2006). The fact that in the aforementioned movies the urban space itself becomes an additional protagonist with its own identity, psychology and the ability to transform and affect other characters, in itself warrants for independent research and analysis. Independently, such mode of presenting urban space has another function; it enables the director to complement the rest of characters. The basis for methodology of this description of cinematographic space is to treat its visual layer as a point of departure for a detailed analysis. At the same time, the analysis itself will be supported by recognised academic theories concerning special issues, which are transformed here into essential tools necessary to describe the world (mise-en-scène) created by González Iñárritu. In ‘Amores perros’ the Mexico City serves as a scenery – a place full of contradictions- in the movie depicted as a modern conglomerate and an urban jungle, as well as a labyrinth of poverty and violence. In this work stylistic tropes can be found in an intertextual dialogue of the director with photographies of Nan Goldin and Mary Ellen Mark. The story recounted in ‘21 Grams’, the most tragic piece in the trilogy, is characterised by almost hyperrealistic sadism. It takes place in Memphis, which on the screen turns into an impersonal formation full of heterotopias described by Michel Foucault and non-places, as defined by Marc Augé in his essay. By contrast, the main urban space in ‘Babel’ is Tokio, which seems to perfectly correspond with the image of places discussed by Juhani Pallasmaa in his works concerning the reception of the architecture by ‘pathological senses’ in the modern (or, even more adequately, postmodern) world. It’s portrayed as a city full of buildings that look so surreal, that they seem to be completely unsuitable for the humans to move between them. Ultimately, the aim of this paper is to demonstrate the coherence of the manner in which González Iñárritu designs urban spaces in his Death Trilogy.

Dehydration, which is based on the reduction of water activity of the fruit, is a common option for overcoming such losses. However, regular hot air drying could affect negatively the quality properties of the fruit due to the long residence time at high temperature. Power ultrasound (US) application during the convective drying has been used as a novel method able to enhance drying rate and, consequently, to decrease drying time. In the present study, a new approach was tested to evaluate the effect of US on the drying time, the final antioxidant activity (AA) and the total polyphenol content (TPC) of banana slices (BS), mango slices (MS) and guava slices (GS). There were also studied the drying kinetics with nine different models from which water effective diffusivities (Deff) (with or without shrinkage corrections) were calculated. Compared with the corresponding control tests, US assisted drying for fruit slices showed reductions in drying time between 16.23 and 30.19%, 11.34 and 32.73%, and 19.25 and 47.51% for the MS, BS and GS respectively. Considering shrinkage effects, Deff calculated values ranged from 1.67*10-10 to 3.18*10-10 m2/s, 3.96*10-10 and 5.57*10-10 m2/s and 4.61*10-10 to 8.16*10-10 m2/s for the BS, MS and GS samples respectively. Reductions of TPC and AA (as DPPH) were observed compared with the original content in fresh fruit data in all kinds of drying assays. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=banana" title="banana">banana</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20diffusivity" title=" effective diffusivity"> effective diffusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=guava" title=" guava"> guava</a>, <a href="https://publications.waset.org/abstracts/search?q=mango" title=" mango"> mango</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/32987/power-ultrasound-application-on-convective-drying-of-banana-musa-paradisiaca-mango-mangifera-indica-l-and-guava-psidium-guajava-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32987.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">535</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">512</span> Airline Choice Model for Domestic Flights: The Role of Airline Flexibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camila%20Amin-Puello">Camila Amin-Puello</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Vasco-Diaz"> Lina Vasco-Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Ramirez-Arias"> Juan Ramirez-Arias</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Munoz"> Claudia Munoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gonzalez-Calderon"> Carlos Gonzalez-Calderon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Operational flexibility is a fundamental aspect in the field of airlines because although demand is constantly changing, it is the duty of companies to provide a service to users that satisfies their needs in an efficient manner without sacrificing factors such as comfort, safety and other perception variables. The objective of this research is to understand the factors that describe and explain operational flexibility by implementing advanced analytical methods such as exploratory factor analysis and structural equation modeling, examining multiple levels of operational flexibility and understanding how these variable influences users' decision-making when choosing an airline and in turn how it affects the airlines themselves. The use of a hybrid model and latent variables improves the efficiency and accuracy of airline performance prediction in the unpredictable Colombian market. This pioneering study delves into traveler motivations and their impact on domestic flight demand, offering valuable insights to optimize resources and improve the overall traveler experience. Applying the methods, it was identified that low-cost airlines are not useful for flexibility, while users, especially women, found airlines with greater flexibility in terms of ticket costs and flight schedules to be more useful. All of this allows airlines to anticipate and adapt to their customers' needs efficiently: to plan flight capacity appropriately, adjust pricing strategies and improve the overall passenger experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20choice%20model" title="hybrid choice model">hybrid choice model</a>, <a href="https://publications.waset.org/abstracts/search?q=airline" title=" airline"> airline</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20travelers" title=" business travelers"> business travelers</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic%20flights" title=" domestic flights"> domestic flights</a> </p> <a href="https://publications.waset.org/abstracts/189374/airline-choice-model-for-domestic-flights-the-role-of-airline-flexibility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189374.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">12</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">511</span> Spontaneous Generation of Wrinkled Patterns on pH-Sensitive Smart-Hydrogel Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carmen%20M.%20Gonzalez-Henriquez">Carmen M.

Additionally, the inhibition of bacterial growth and, therefore, their antimicrobial activity, can be used as dual-functional antifogging/antimicrobial polymer coatings. According to their interesting physicochemical characteristics and biocompatible properties, DMAEMA was used as a monomer to synthesize a smart pH-sensitive hydrogel, namely poly(HEMA-co-PEGDA575-co-DMAEMA). Thus, different mole ratios (ranging from 5:1:0 to 0:1:5, according to the mole ratio between HEMA, PEGDA, and DEAEMA, respectively) were used in this research. The surface patterns formed via a two-step polymerization (redox- and photo-polymerization) were first chemically studied via 1H-NMR and elemental analysis. Secondly, the samples were morphologically analyzed by using Field-Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) techniques. Then, a particular relation between HEMA, PEGDA, and DEAEMA (0:1:5) was also characterized at three different pH (5.4, 7.4 and 8.3). The hydrodynamic radius and zeta potential of the micro-hydrogel particles (emulsion) were carried out as a possible control for morphology, exploring the effect that produces hydrogel micelle dimensions in the wavelength, height, and roughness of the wrinkled patterns. Finally, contact angle and cross-hatch adhesion test was carried out for the hydrogels supported on glass using TSM-silanized surfaces in order to measure their mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wrinkled%20patterns" title="wrinkled patterns">wrinkled patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20pH-sensitive%20hydrogels" title=" smart pH-sensitive hydrogels"> smart pH-sensitive hydrogels</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel%20micelle%20diameter" title=" hydrogel micelle diameter"> hydrogel micelle diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion%20tests" title=" adhesion tests"> adhesion tests</a> </p> <a href="https://publications.waset.org/abstracts/84736/spontaneous-generation-of-wrinkled-patterns-on-ph-sensitive-smart-hydrogel-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84736.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">206</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">510</span> Development and Automation of Medium-Scale NFT Hydroponic Systems: Design Methodology and State of the Art Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Armando%20Gonz%C3%A1lez-Marin">Oscar Armando González-Marin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhon%20F.%20Rodr%C3%ADguez-Le%C3%B3n"> Jhon F.

In addition, the overexploitation of agricultural lands, combined with food and water scarcity, has highlighted the urgent need for sustainable cultivation methods. Hydroponics has emerged as a sustainable farming technique that enables plant cultivation using nutrient solutions without the requirement for traditional soil. Among hydroponic methods, the Nutrient Film Technique (NFT) facilitates plant growth by circulating a nutrient solution continuously. This approach allows the monitoring and precise control of nutritional parameters, with potential for automation and technological integration. This study aims to present the state of the art of automated NFT hydroponic systems, discussing their design methodologies and considerations for implementation. Moreover, a medium-scale NFT system developed at CICATA-QRO is introduced, detailing its current manual management and progress toward automation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroponics" title=" hydroponics"> hydroponics</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20film%20technique" title=" nutrient film technique"> nutrient film technique</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/192149/development-and-automation-of-medium-scale-nft-hydroponic-systems-design-methodology-and-state-of-the-art-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192149.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">39</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">509</span> Availability Strategy of Medical Information for Telemedicine Services</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rozo%20D.%20Juan%20Felipe">Rozo D.

In addition, to evaluate the quality-of-service parameters, the followings were measured: delays, throughput, jitter, latency, available bandwidth, percent of access and denial of services based of web management performance map with profiles permissions and database management. Through 24 different test scenarios, the results show 100% in availability of medical information, in relation to access of medical staff to web services, and quality of service (QoS) of 99% because of network delay and performance of computer network. The findings of this study suggest that the proposed strategy of web management is an ideal solution to guarantee the availability, reliability, and accessibility of medical information.

This is far from the objectives determined in the European Directive for 2020 and aware of this situation, the European Countries are implementing national policies to prevent the waste that can be avoidable and to promote measures to increase recycling and recovering. In Spain, one of these measures has been the development of a CDW recycling guide for the manufacture of mortar, concrete, bricks and lightweight aggregates. However, there is still not enough information on the possibility of incorporating CDW materials in the manufacture of gypsum products. In view of the foregoing, the Universidad Politécnica de Madrid is creating a database with information on the possibility of incorporating CDW materials in the manufacture of gypsum products. The objective of this study is to improve this database by analysing the feasibility of incorporating two different CDW in a gypsum matrix: ceramic waste bricks (perforated brick and double hollow brick), and extruded polystyrene (XPS) waste. Results show that it is possible to incorporate up to 25% of ceramic waste and 4% of XPS waste over the weight of gypsum in a gypsum matrix. Furhtermore, with the addition of ceramic waste an 8% of surface hardness increase and a 25% of capillary water absorption reduction can be obtained. On the other hand, with the addition of XPS, a 26% reduction of density and a 37% improvement of thermal conductivity can be obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CDW" title="CDW">CDW</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20materials" title=" waste materials"> waste materials</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20waste" title=" ceramic waste"> ceramic waste</a>, <a href="https://publications.waset.org/abstracts/search?q=XPS" title=" XPS"> XPS</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20materials" title=" construction materials"> construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=gypsum" title=" gypsum"> gypsum</a> </p> <a href="https://publications.waset.org/abstracts/24751/gypsum-composites-with-cdw-as-raw-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24751.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">510</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">507</span> N Doped Multiwall Carbon Nanotubes Growth over a Ni Catalyst Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angie%20Quevedo">Angie Quevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Bussi"> Juan Bussi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nestor%20Tancredi"> Nestor Tancredi</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Fajardo-D%C3%ADaz"> Juan Fajardo-Díaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Florentino%20L%C3%B3pez-Ur%C3%ADas"> Florentino López-Urías</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilio%20Mu%C3%B1%C3%B3z-Sandoval"> Emilio Muñóz-Sandoval</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study the carbon nanotubes (CNTs) formation by catalytic chemical vapor deposition (CCVD) over a catalyst with 20 % of Ni supported over La₂Zr₂O₇ (Ni20LZO). The high C solubility of Ni made it one of the most used in CNTs synthesis. Nevertheless, Ni presents also sintering and coalescence at high temperature. These troubles can be reduced by choosing a suitable support. We propose La₂Zr₂O₇ as for this matter since the incorporation of Ni by co-precipitation and calcination at 900 °C allows a good dispersion and interaction of the active metal (in the oxidized form, NiO) with this support. The CCVD was performed using 1 g of Ni20LZO at 950 °C during 30 min in Ar:H₂ atmosphere (2.5 L/min). The precursor, benzylamine, was added by a nebulizer-sprayer. X ray diffraction study shows the phase separation of NiO and La₂Zr₂O₇ after the calcination and the reduction to Ni after the synthesis. Raman spectra show D and G bands with a ID/IG ratio of 0.75. Elemental study verifies the incorporation of 1% of N. Thermogravimetric analysis shows the oxidation process start at around 450 °C. Future studies will determine the application potential of the samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=N%20doped%20carbon%20nanotubes" title="N doped carbon nanotubes">N doped carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=catalytic%20chemical%20vapor%20deposition" title=" catalytic chemical vapor deposition"> catalytic chemical vapor deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20catalyst" title=" nickel catalyst"> nickel catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=bimetallic%20oxide" title=" bimetallic oxide"> bimetallic oxide</a> </p> <a href="https://publications.waset.org/abstracts/125152/n-doped-multiwall-carbon-nanotubes-growth-over-a-ni-catalyst-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125152.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">162</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">506</span> Spawning Induction and Early Larval Development of the Giant Reef Clam Periglypta multicostata (Sowerby, 1835) under Controlled Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Melena">Jose Melena</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Santander"> Rosa Santander</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanya%20Gonzalez"> Tanya Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Duque"> Richard Duque</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Illanes"> Juan Illanes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecuador is one of the countries with the greatest aquatic biodiversity worldwide. In particular, there are at least a dozen native marine species with great aquaculture potential locally. This research concerns one of those species. It has proposed to implement experimental protocols in order to induce spawning and to generate the early larval development of the giant reef clam P. multicostata under controlled conditions. Bioassays were carried out with one adult batch (n= 8) with an average valvar length of 118,4 ± 5,8 mm, which were collected near of the Puerto Santa Rosa (2° 12' 30'' S, 80° 58' 28'' W), Santa Elena Province. During a short acclimation stage, the eight adults of giant reef clam P. multicostata were exposed to thermal stress. Briefly, the experimental protocol for spawning induction was based on the application of 20°C for 1 h and 30°C for 1 h on P. multicostata broodstock at least three consecutive times by one day. After spawning, collected sexual material was released for external fertilization process. After the delivery of gametes, it was achieved 3,25 × 10⁶ viable zygotes. As results, fertilized eggs had 56 µm diameter; while first and second cell divisions were observed to 2,5 h post-fertilization, with individual average length of 68 ± 5 µm and polar body. Latter cell divisions, including gastrula stage, appeared at 9 h post-fertilization, with individual average length of 73 ± 4 µm and trochophore stage at 15 h post-fertilization with individual average length of 75 ± 4 µm.

Objective: determine the characteristics of the use of alternative and complementary therapies in patients with chronic pain who consulted in a medical institution. Methodology: cross-sectional and descriptive study, with a population of patients that assisted to the outpatient consultation and met the eligibility criteria. Sampling was not conducted. A form was used for the collection of demographic and clinical variables and the Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) was validated. The analysis and processing of information was carried out using the SPSS program vr.19. Results: 220 people with chronic pain were included. The average age was 54.7±16.2 years, 78.2% were women, and 75.5% belonged to the socioeconomic strata 1 to 3. Musculoskeletal pain (77.7%), migraine (15%) and neuralgia (9.1%) were the most frequently types of chronic pain. 33.6% of participants have used some kind of alternative and complementary therapy; the most frequent were: homeopathy (14.5%), phytotherapy (12.7%), and acupuncture (11.4%). The total average HCAMQ score for the study group was 30.2±7.0 points, which shows a moderate attitude toward the use of complementary and alternative medicine. The highest scores according to the type of pain were: neuralgia (32.4±5.8), musculoskeletal pain (30.5±6.7), fibromyalgia (29.6±7.3) and migraine (28.5±8.8). The reliability of the HCAMQ was acceptable (Cronbach's α: 0.6). Conclusion: it was noted that the types of chronic pain and the clinical or therapeutic management of patients correspond to the data available in current literature. Despite the moderate attitude toward the use of these alternative and complementary therapies, one of every three patients uses them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20pain" title="chronic pain">chronic pain</a>, <a href="https://publications.waset.org/abstracts/search?q=complementary%20therapies" title=" complementary therapies"> complementary therapies</a>, <a href="https://publications.waset.org/abstracts/search?q=homeopathy" title=" homeopathy"> homeopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=acupuncture%20analgesia" title=" acupuncture analgesia"> acupuncture analgesia</a> </p> <a href="https://publications.waset.org/abstracts/41720/use-of-alternative-and-complementary-therapies-in-patients-with-chronic-pain-in-a-medical-institution-in-medellin-colombia-2014" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41720.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">515</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">504</span> Effects of an Inclusive Educational Model for Students with High Intellectual Capacity and Special Educational Needs: A Case Study in Talentos UdeC, Chile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gracia%20V.%20Navarro">Gracia V.

This paper describes a model for the educational inclusion of students, with special educational needs associated with high intellectual capacity, developed at the University of Concepción and its effects on its students, academics and undergraduate students that collaborate with the program. The Talentos UdeC Program was created in 2003 and is intended for 240 children and youth from 11 to 18 years old, from 15 communes of the Biobio region. The case Talentos UdeC is analyzed from a mixed qualitative study in which those participating in the educational model are considered. The sample was composed of 30 students, 30 academics, and 30 undergraduate students. In the case of students, pre and post program measurements were made to analyze their socio-emotional adaptation, academic motivation and socially responsible behavior. The mentioned variables are measured through questionnaires designed and validated by the University of Concepcion that included: The Socially Responsible Behavior Questionnaire (CCSR); the Academic Motivation Questionnaire (CMA) and the Socio-Emotional Adaptation Questionnaire (CASE). The information obtained by these questionnaires was analyzed through a quantitative analysis. Academics and undergraduate students were interviewed to learn their perception of the effects of the program on themselves, on students and on society. The information obtained is analyzed using qualitative analysis based on the identification of common themes and descriptors for the construction of conceptual categories of answers. Quantitative results show differences in the first three variables analyzed in the students, after their participation for two years in Talentos UdeC. Qualitative results demonstrate perception of effects in the vision of world, project of life and in other areas of the students’ development; perception of effects in a personal, professional and organizational plane by academics and a perception of effects in their personal-social development and training in generic competencies by undergraduates students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20model" title="educational model">educational model</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20intellectual%20capacity" title=" high intellectual capacity"> high intellectual capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20educational%20needs" title=" special educational needs"> special educational needs</a> </p> <a href="https://publications.waset.org/abstracts/84186/effects-of-an-inclusive-educational-model-for-students-with-high-intellectual-capacity-and-special-educational-needs-a-case-study-in-talentos-udec-chile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84186.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">220</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">503</span> Spawning Induction and Early Larval Development of the Penshell Atrina maura (Sowerby, 1835) under Controlled Conditions in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Melena">Jose Melena</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Santander"> Rosa Santander</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanya%20Gonzalez"> Tanya Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Duque"> Richard Duque</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Illanes"> Juan Illanes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecuador is one of the countries with the greatest aquatic biodiversity worldwide. In particular, there are at least a dozen native marine species with great aquaculture potential locally. This research concerns one of those species. It has proposed to implement experimental protocols in order to induce spawning and to generate the early larval development of the penshell Atrina maura under controlled conditions. Bioassays were carried out with one adult batch (n= 26) with an average valvar length of 307,6 ± 9,4 mm, which were collected in the Puerto El Morro Mangrove (2° 42' 33'' S, 80° 14' 28'' W), Guayas Province. During a short acclimation stage, five adults of penshell A. maura were sacrificed in order to determine their sexual maturity degree and to estimate their sex ratio. Dissection showed that three were ripe females (60%) and two were ripe males (40%). Later, three groups (n= 7 by each) were tested with two treatments in order to induce the broodstock spawning: thermal stress, osmotic shock, and one control. Spawning induction was achieved by the immersion in water to 0 g L⁻¹ per 1 h and immersion in sea water to 34 g L⁻¹ per 1 h. After the delivery of gametes, it was achieved 1,35 × 10⁶ viable zygotes. As results, fertilized eggs had 60 µm diameter; while first and second cell divisions were observed to 1 h post-fertilization, with individual average length of 65 ± 4 µm and polar body. Latter cell divisions, including gastrula stage, appeared at 9 h post-fertilization, with individual average length of 71 ± 4 µm; and trochophore stage at 16 h post-fertilization with individual average length of 75 ± 5 µm. In addition, veliger stage was registered at 20 h post-fertilization with individual average length of 81 ± 5 µm. Umboned larvae appeared at day 8 post-fertilization, with individual average length of 145 ± 6 µm. These pioneering results in Ecuador can strengthen the local conservation process of the overexploited A. maura and to encourage its production for commercial purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atrina%20maura" title="Atrina maura">Atrina maura</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=larval%20development" title=" larval development"> larval development</a>, <a href="https://publications.waset.org/abstracts/search?q=spawning%20induction" title=" spawning induction"> spawning induction</a> </p> <a href="https://publications.waset.org/abstracts/103256/spawning-induction-and-early-larval-development-of-the-penshell-atrina-maura-sowerby-1835-under-controlled-conditions-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103256.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">163</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">502</span> Technology in the Calculation of People Health Level: Design of a Computational Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Herrero%20Ja%C3%A9n">Sara Herrero Jaén</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Mar%C3%ADa%20Santamar%C3%ADa%20Garc%C3%ADa"> José María Santamaría García</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Lourdes%20Jim%C3%A9nez%20Rodr%C3%ADguez"> María Lourdes Jiménez Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Luis%20G%C3%B3mez%20Gonz%C3%A1lez"> Jorge Luis Gómez González</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Cercas%20Duque"> Adriana Cercas Duque</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Gonz%C3%A1lez%20Aguna"> Alexandra González Aguna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Health concept has evolved throughout history. The health level is determined by the own individual perception. It is a dynamic process over time so that you can see variations from one moment to the next. In this way, knowing the health of the patients you care for, will facilitate decision making in the treatment of care. Objective: To design a technological tool that calculates the people health level in a sequential way over time. Material and Methods: Deductive methodology through text analysis, extraction and logical knowledge formalization and education with expert group. Studying time: September 2015- actually. Results: A computational tool for the use of health personnel has been designed. It has 11 variables. Each variable can be given a value from 1 to 5, with 1 being the minimum value and 5 being the maximum value. By adding the result of the 11 variables we obtain a magnitude in a certain time, the health level of the person. The health calculator allows to represent people health level at a time, establishing temporal cuts being useful to determine the evolution of the individual over time. Conclusion: The Information and Communication Technologies (ICT) allow training and help in various disciplinary areas. It is important to highlight their relevance in the field of health. Based on the health formalization, care acts can be directed towards some of the propositional elements of the concept above. The care acts will modify the people health level. The health calculator allows the prioritization and prediction of different strategies of health care in hospital units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calculator" title="calculator">calculator</a>, <a href="https://publications.waset.org/abstracts/search?q=care" title=" care"> care</a>, <a href="https://publications.waset.org/abstracts/search?q=eHealth" title=" eHealth"> eHealth</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a> </p> <a href="https://publications.waset.org/abstracts/82489/technology-in-the-calculation-of-people-health-level-design-of-a-computational-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82489.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">264</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">501</span> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals.
