However, in this country, few products with low adding-value are produced from the tuber and none from cassava by-products. To our best knowledge, lactic acid was produced from Ecuadorian cassava bagasse starch in a biotechnological way. The objective of this contribution was to study the influence of the fermentation variables (pH and agitation) on the lactic acid production of Ecuadorian cassava varieties from bagasse starch. Enzymatic hydrolysis of cassava bagasse starch for INIAP 650 and INIAP 651 varieties spread in Ecuador was performed using α-amylase and amyloglucosidase. Then, glucose was fermented by Lactobacillus leichmannii strains in different conditions of agitation (0 and 150 rpm) and pH (4.5, 5.0, and 5.5). Significant differences in ash, fibre, protein, lipids, and amylose were found in cassava bagasse starch of INIAP 650 and INIAP 651 with 1.4 and 1.3%, 4.3 and 6%, 1.2 and 2.1%, 1.9 and 1.5%, and 24.3 and 26.5%, respectively. The determination of lactic acid was performed by potentiometric and FTIR analysis. Conversions of cassava bagasse to reduced sugars were 71.7 and 85.1% for INIAP 650 and INIAP 651, respectively. The best lactic acid concentrations were 27.6 and 33.5 g/L, obtained at agitation 150 rpm and pH 5.5 for INIAP 650 and INIAP 651. Qualitative analysis conducted by FTIR spectrophotometry confirmed the presence of lactic acid in the reacted products. This investigation could contribute to the valorisation of residues from promising cassava varieties in Ecuador and hence to increase the development of this country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bagasse%20starch" title="bagasse starch">bagasse starch</a>, <a href="https://publications.waset.org/abstracts/search?q=cassava" title=" cassava"> cassava</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid" title=" lactic acid"> lactic acid</a> </p> <a href="https://publications.waset.org/abstracts/136271/assessment-of-cassava-varieties-in-ecuador-for-the-production-of-lactic-acid-from-starch-by-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136271.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">193</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">68</span> Modeling and Simulation of a Hybrid System Solar Panel and Wind Turbine in the Quingeo Heritage Center in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Portoviejo%20Brito">Juan Portoviejo Brito</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Icaza%20Alvarez"> Daniel Icaza Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Castro%20Samaniego"> Christian Castro Samaniego</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we present the modeling, simulations, and energy conversion analysis of the solar-wind system for the Quingeo Heritage Center in Ecuador. A numerical model was constructed based on the 19 equations, it was coded in MATLAB R2017a, and the results were compared with the experimental data of the site. The model is built with the purpose of using it as a computer development for the optimization of resources and designs of hybrid systems in the Parish of Quingeo and its surroundings. The model obtained a fairly similar pattern compared to the data and curves obtained in the field experimentally and detailed in manuscript. It is important to indicate that this analysis has been carried out so that in the near future one or two of these power generation systems can be exploited in a massive way according to the budget assigned by the Parish GAD of Quingeo or other national or international organizations with the purpose of preserving this unique colonial helmet in Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20system" title="hybrid system">hybrid system</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title=" wind turbine"> wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Smart%20Grid" title=" Smart Grid"> Smart Grid</a>, <a href="https://publications.waset.org/abstracts/search?q=Quingeo%20Azuay%20Ecuador" title=" Quingeo Azuay Ecuador"> Quingeo Azuay Ecuador</a> </p> <a href="https://publications.waset.org/abstracts/89770/modeling-and-simulation-of-a-hybrid-system-solar-panel-and-wind-turbine-in-the-quingeo-heritage-center-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89770.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">269</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">67</span> Analysis of Energy Required for the Massive Incorporation of Electric Buses in the City of Ambato - Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Quintana">Paola Quintana</a>, <a href="https://publications.waset.org/abstracts/search?q=Ang%C3%A9lica%20Vaca"> Angélica Vaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebasti%C3%A1n%20Villacres"> Sebastián Villacres</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Acurio"> Henry Acurio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecuador through the Organic Law of Energy Efficiency establishes that "Starting in the year 2025, all vehicles that are incorporated into the urban and inter-parroquial public transport service must only be electric”, this marks a foundation for the introduction of electric mobility in the country.

This project, under the guidance of Dr. Michael Harris from the Florida Atlantic University, seeks to understand how the role of an ama de casa provides a secure environment for men and women, coexists with economic and environmental constraints that explain the origins of how this environment has been formed. The coastal community aspects of familia (family), trabajo (work), relación (relationships), machismo (masculinity), feminista (femininity), and the culture of Ecuador define the ways of life in a coastal setting. This ethnographic research project included the following methodologies: environment mapping, conducting interviews, surveys, participant observation, direct and indirect observations, and integration into daily life. Immersion into the daily life and building relationships with the local people allowed the documentation of intricacies of both the cultural and social spheres. The findings of this research offer insight on how culture, economics, and environment can form female and male agency. Our investigation shows that occupations such as fishermen, laborers, ama de casas, and even students utilize occupational routes to create social agency in the face of economic and environmental constraints in Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title="Ecuador">Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnography" title=" ethnography"> ethnography</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20division%20of%20labor" title=" gender division of labor"> gender division of labor</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20roles" title=" gender roles"> gender roles</a> </p> <a href="https://publications.waset.org/abstracts/87503/ama-de-casa-gender-division-of-labor-the-response-to-environmental-and-economic-constraints-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">242</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Renewable Energy System Eolic-Photovoltaic for the Touristic Center La Tranca-Chordeleg in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Castro%20Samaniego">Christian Castro Samaniego</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Icaza%20Alvarez"> Daniel Icaza Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Portoviejo%20Brito"> Juan Portoviejo Brito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For this research work, hybrid wind-photovoltaic (SHEF) systems were considered as renewable energy sources that take advantage of wind energy and solar radiation to transform into electrical energy.

Authenticity of Ecuadorian commercial honeys was tested with a vortex emulsion consisting on one volume of honey:water (1:1) dilution, and two volumes of diethyl ether. This method allows a separation of phases in one minute to discriminate genuine honeys that form three phase and fake honeys that form two phases; 34 of the 42 honeys analyzed from five provinces of Ecuador were genuine. This was confirmed with 1H NMR spectra of honey dilutions in deuterated water with an enhanced aminoacid region with signals for proline, phenylalanine and tyrosine. Classic quality indicators were also tested with this method (sugars, HMF), indicators of fermentation (ethanol, acetic acid), and residues of citric acid used in the syrup manufacture. One of the honeys gave a false positive for genuine, being an admixture of genuine honey with added syrup, evident for the high sucrose. Sensory analysis was the final confirmation to recognize the honey groups studied here, namely honey produced in combs by Apis mellifera, fake honey, and honey produced in cerumen pots by Geotrigona, Melipona, and Scaptotrigona. This is a valuable contribution to protect honey consumers, and to develop the beekeeping industry in Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fake" title="fake">fake</a>, <a href="https://publications.waset.org/abstracts/search?q=genuine" title=" genuine"> genuine</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=1H%20NMR" title=" 1H NMR"> 1H NMR</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador "> Ecuador </a> </p> <a href="https://publications.waset.org/abstracts/28018/authenticity-of-ecuadorian-commercial-honeys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28018.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">385</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">63</span> Transformation of the Institutionality of International Cooperation in Ecuador from 2007 to 2017: 2017: A Case of State Identity Affirmation through Role Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Carolina%20Encalada%20Castillo">Natalia Carolina Encalada Castillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As part of an intended radical policy change compared to former administrations in Ecuador, the transformation of the institutionality of international cooperation during the period of President Rafael Correa was considered as a key element for the construction of the state of 'Good Living'. This intention led to several regulatory changes in the reception of cooperation for development, and even the departure of some foreign cooperation agencies. Moreover, Ecuador launched the initiative to become a donor of cooperation towards other developing countries through the ‘South-South Cooperation’ approach. All these changes were institutionalized through the Ecuadorian System of International Cooperation as a new framework to establish rules and policies that guarantee a sovereign management of foreign aid. Therefore, this research project has been guided by two questions: What were the factors that motivated the transformation of the institutionality of international cooperation in Ecuador from 2007 to 2017? and, what were the implications of this transformation in terms of the international role of the country? This paper seeks to answer these questions through Role Theory within a Constructivist meta-theoretical perspective, considering that in this case, changes at the institutional level in the field of cooperation, responded not only to material motivations but also to interests built on the basis of a specific state identity. The latter was only possible to affirm through specific roles such as ‘sovereign recipient of cooperation’ as well as ‘donor of international cooperation’. However, the performance of these roles was problematic as they were not easily accepted by the other actors in the international arena or in the domestic level. In terms of methodology, these dynamics are analyzed in a qualitative way mainly through interpretive analysis of the discourse of high-level decision-makers from Ecuador and other cooperation actors. Complementary to this, document-based research of relevant information as well as interviews have been conducted. Finally, it is concluded that even if material factors such as infrastructure needs, trade and investment interests, as well as reinforcement of state control and monitoring of cooperation flows, motivated the institutional transformation of international cooperation in Ecuador; the essential basis of these changes was the search for a new identity for the country to be projected in the international arena. This identity started to be built but continues to be unstable. Therefore, it is important to potentiate the achievements of the new international cooperation policies, and review their weaknesses, so that non-reimbursable cooperation funds received as well as ‘South-South cooperation’ actions, contribute effectively to national objectives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title="Ecuador">Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20cooperation" title=" international cooperation"> international cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=Role%20Theory" title=" Role Theory"> Role Theory</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20identity" title=" state identity"> state identity</a> </p> <a href="https://publications.waset.org/abstracts/103623/transformation-of-the-institutionality-of-international-cooperation-in-ecuador-from-2007-to-2017-2017-a-case-of-state-identity-affirmation-through-role-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103623.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">212</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">62</span> Proposal of Methodology Based on Technical Characterization and Quantitative Contrast of Co₂ Emissions for the Migration to Electric Mobility of the Vehicle Fleet: Case Study of Electric Companies in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20I.%20Ullauri">Rodrigo I.

The transportation sector is a significant consumer of fossil fuels and contributes significantly to greenhouse gas emissions. The current challenge is to find ways to reduce the use of fossil fuels in transportation. In Ecuador, where 92% of electricity is generated from clean sources, the concept of e-mobility is considered an attractive alternative to address the challenge of sustainable mobility. The proposal is to migrate from combustion-powered vehicles to electric vehicles in the electric companies of Ecuador, using a methodology to standardize criteria, determine specific requirements, contrast technical characteristics, and estimate emission reductions. The results showed that there are three categories of vehicles that have electric counterparts suitable for performing activities under certain operation parameters inherent to current technology limitations but with a significant contribution to the reduction of annual CO₂ emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=electro%20mobility" title=" electro mobility"> electro mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20transportation" title=" sustainable transportation"> sustainable transportation</a> </p> <a href="https://publications.waset.org/abstracts/161828/proposal-of-methodology-based-on-technical-characterization-and-quantitative-contrast-of-co2-emissions-for-the-migration-to-electric-mobility-of-the-vehicle-fleet-case-study-of-electric-companies-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161828.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">89</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">61</span> The Other Dreamers: A Study of the Relationship between Returned Migration and Entrepreneurship</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pascual%20Garc%C3%ADa">Pascual García</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Ochoa"> Francisco Ochoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Ordo%C3%B1ez"> Jessica Ordoñez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The links between migration and development have been widely written and analyzed from different perspectives. However, the nexus between entrepreneurship and migration is of recent interest. The different studies related to this have focused on the ventures of ethnic enclaves, or on transnational businesses, which link the community of origin and destination. Beyond this perspective, this work analyzes the return migration, (a few studies until now, but forming part of a theoretical body of migration). As a result of the European crisis started between 2007-2008. Many Ecuadorians who lived in Europe, decided to return to their place of origin. The rise of the price of the oil and commodities presented a better panorama in Ecuador than in Europe. Faced with the magnitude of returnees, the opportunities for entrepreneurship in Ecuador increased (Accumulation of human capital, social capital, learned skills and capital). Thus there is an interest in the possibility of returned migrants in the country to start a business in their place of origin. The following study is the result of this. A survey of 110 returned migrants was carried out in the south of Ecuador and, using a Probit econometric model, we determined that the variables specified as geographic area, sex, education level are not significant, so they are not determinant when undertaking. However, time abroad and skills learned, if they were significant at the time of the decision to start a business. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=returned%20migration" title=" returned migration"> returned migration</a> </p> <a href="https://publications.waset.org/abstracts/81793/the-other-dreamers-a-study-of-the-relationship-between-returned-migration-and-entrepreneurship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81793.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">210</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">60</span> Entomological Origin of Honey Discriminated by NMR Chloroform Extracts in Ecuadorian Honey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Vit">P.

We studied honey produced in beeswax combs by Apis mellifera, and honey produced in pots by Geotrigona and Scaptotrigona bees. Chloroform extracts of honey were obtained for fast NMR spectra. The 1D spectra were acquired at 298 K, with a 600 MHz NMR Bruker instrument, using a modified double pulsed field gradient spin echoes (DPFGSE) sequence. Signals of 1H NMR spectra were integrated and used as inputs for PCA, PLS-DA analysis, and labelled sets of classes were successfully identified, enhancing the separation between the three groups of honey according to the entomological origin: A. mellifera, Geotrigona and Scaptotrigona. This procedure is therefore recommended for authenticity test of honey in Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apis%20mellifera" title="Apis mellifera">Apis mellifera</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=1H%20NMR" title=" 1H NMR"> 1H NMR</a>, <a href="https://publications.waset.org/abstracts/search?q=entomological%20origin" title=" entomological origin"> entomological origin</a>, <a href="https://publications.waset.org/abstracts/search?q=meliponini" title=" meliponini "> meliponini </a> </p> <a href="https://publications.waset.org/abstracts/24309/entomological-origin-of-honey-discriminated-by-nmr-chloroform-extracts-in-ecuadorian-honey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24309.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">401</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">59</span> Failing to Protect Bare Life During the COVID-19 Pandemic: Forced Migrants as Carriers of the Virus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Donoso">Claudia Donoso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study compares the restriction of mobility of migrants and asylum seekers during the COVID-19 pandemic in the United States and Ecuador. Based on the discourse analysis of anti-migrant rhetoric in press articles, migrant stories in the press, reports, and border control practices, the study examines the Ecuadorian government’s response to the migration flow of Venezuelans and the United States enforcement practices against Latin American asylum seekers. By exploring Giorgio Agamben’s concept of bare life, the article argues that this failure to protect mobility rights is due to the United States and Ecuador’s views of forced migrants as bare life and carriers of the virus, justifying xenophobia, resistance to humanitarian international law, and exceptionalism. By drawing on a feminist intersectional approach, the study adds to recent research on the securitization of forced migration and challenge the race/ethnicity, immigration status, class, and nationality-based discrimination of the measures undertaken during the pandemic. The article illustrates how the treatment of forced migrants as bare life was aggravated by their intersectional inequalities. It concludes by providing recommendations that could be enforced by the US and Ecuadorian governments to protect the right to freedom of mobility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bare%20life" title="bare life">bare life</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility%20rights" title=" mobility rights"> mobility rights</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20States" title=" United States"> United States</a> </p> <a href="https://publications.waset.org/abstracts/162177/failing-to-protect-bare-life-during-the-covid-19-pandemic-forced-migrants-as-carriers-of-the-virus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162177.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</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">57</span> The Role of the Returned Migration in the Regional Economic Growth </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Ordo%C3%B1ez">Jessica Ordoñez</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Ochoa"> Francisco Ochoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascual%20%20Garc%C3%ADa"> Pascual García </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this paper is to analyze the relationship between return migration in Ecuador and economic growth. The improvement of macroeconomic conditions in Latin America, starting in 2012, makes the region a new migratory destination, in both senses in north-south and south-south flows. Current studies highlight only the role of the entrepreneurial migrant in generating employment and economic growth in the region. Nevertheless, it has not been considered that not all migrants are entrepreneurs and that not all entrepreneurs contribute to economic growth. This research compares the socioeconomic and labor characteristics of migrant returnees working as freelancers in Ecuador. The principal aim is to demystify the role of migrant entrepreneurs in regional growth and to identify socioeconomic characteristics that can enhance growth. A panel econometric model was used, which is part of the information from labor and macroeconomic surveys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title="economic growth">economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneur" title=" entrepreneur"> entrepreneur</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=returned%20migration" title=" returned migration"> returned migration</a> </p> <a href="https://publications.waset.org/abstracts/81816/the-role-of-the-returned-migration-in-the-regional-economic-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81816.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">211</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">56</span> The Experience of Community-based Tourism in Yunguilla, Ecuador and Its Social-Cultural Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=York%20Neudel">York Neudel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The phenomenon of tourism has been considered as tool to overcome cultural frontiers, to comprehend the other and to cope with mutual mistrust and suspicion. Well, that has been a myth, at least when it comes to mass-tourism. Other approaches, like community-based tourism, still are based on the idea of embracing the other in order to help or to understand the cultural difference. In 1997, two American NGOs incentivized a tourism-project in a community in the highlands of Ecuador, in order to protect the cloud forest from destructive exploitation of its own inhabitants. Nineteen years after that, I analyze in this investigation the interactions between the Ecuadorian hosts in the mestizo-community of Yunguilla and the foreign tourist in the quest for “authentic life” in the Ecuadorian cloud forest. As a sort of “contemporary pilgrim” the traveller tries to find authenticity in other times and places far away from their everyday life in Europe or North America. Therefore, tourists are guided by stereotypes and expectations that are produced by the touristic industry. The host, on the other hand, has to negotiate this pre-established imaginary. That generates a kind of theatre-play with front- and backstage in organic gardens, little fabrics and even private housing, since this alternative project offers to share the private space of the host with the tourist in the setting the community-based tourism. In order to protect their privacy, the community creates new hybrid spaces that oscillate between front- and backstages that culminates in a game of hide and seek – a phenomenon that promises interesting frictions for an anthropological case-study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tourism" title="Tourism">Tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=Authenticity" title=" Authenticity"> Authenticity</a>, <a href="https://publications.waset.org/abstracts/search?q=Community-based%20tourism" title=" Community-based tourism"> Community-based tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=Yunguilla" title=" Yunguilla"> Yunguilla</a> </p> <a href="https://publications.waset.org/abstracts/47846/the-experience-of-community-based-tourism-in-yunguilla-ecuador-and-its-social-cultural-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47846.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">284</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">55</span> Decolonial Theorization of Epistemic Agency in Language Policy Management: Case of Plurinational Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Madany-Sa%C3%A1">Magdalena Madany-Saá</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper compares the language management of two language policies in plurinational Ecuador: (1) mandatory English language teaching that uses Western standards of quality, and (2) indigenous educación intercultural bilingüe, which promotes ancestral knowledge and the indigenous languages of Ecuador. The data are from a comparative institutional ethnography conducted between 2018 and 2022 in English and Kichwa teacher preparation programs in an Ecuadorian teachers’ college. Specifically, the paper explores frameworks of knowledge promoted by different educational actors in both teacher education programs and the ways in which the Ecuadorian transformation towards a knowledge-based economy is intertwined with the country’s linguistic policies. Focusing on the specific role of language advocates and their discursive role in knowledge production, the paper elaborates on the notion of agency in Language Policy and Planning (LPP), referred to as epistemic agency. Specifically, the epistemic agency is conceptualized through the analysis of English language epistemic advocates who participate in empowering English language policies and endorse knowledge production in that language. By proposing an epistemic agency, this paper argues that in the context of knowledge-based societies, advocates are key in transferring the policies from the political to the epistemic realm – where decisions about what counts as legitimate knowledge are made. The study uses the decolonial option as its analytical framework for critiquing the hegemonic perpetuation of modernity and its knowledge-based models in Latin America derived from the colonial matrix of power. Through this theoretical approach, it is argued that if indigenous stakeholders are only viewed as political actors and not as knowledge producers, the hegemony of Global English will reinforce a knowledge-based society constructed upon Global North modernity. In the absence of strong epistemic advocates for indigenous language policies, powerful Global English advocates occupy such vacancies at the language management level, thus dominating the ecology of knowledge in a plurinational and plurilingual Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educaci%C3%B3n%20intercultural%20biling%C3%BCe" title="educación intercultural bilingüe">educación intercultural bilingüe</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20language%20teaching" title=" English language teaching"> English language teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=epistemic%20agency" title=" epistemic agency"> epistemic agency</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20advocates" title=" language advocates"> language advocates</a>, <a href="https://publications.waset.org/abstracts/search?q=plurinationality" title=" plurinationality"> plurinationality</a> </p> <a href="https://publications.waset.org/abstracts/186848/decolonial-theorization-of-epistemic-agency-in-language-policy-management-case-of-plurinational-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186848.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">36</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">54</span> Combined Effect of Gluten-Free Superfoods and by-Products from Ecuador to Evaluate the Functional and Sensory Properties of Breadmaking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Vasquez">Andrea Vasquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Maldonado-Alvarado"> Pedro Maldonado-Alvarado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In general, 'gluten-free' foods like breadmaking products provide functional or nutraceutical benefits for the consumer's health and increased their demand on the market. In Ecuador, there is an overproduction of superfoods, and the food by-products are undervalued. For the first time, to the author's best knowledge, gluten-free bread mixtures from quinoa and banana flour, cassava starch, lupine flour (LF), or whey protein (WP) with hydroxypropylmethylcellulose (HPMC) and transglutaminase (TG) were evaluated on their functional and sensory properties. Free amino groups and thiols, rheology, and electrophoresis SDS PAGE were performed to analyze the crosslinking of TG at different concentrations with HC or PL proteins. Dough characterization, pasting properties were evaluated, respectively, by a MIXOLAB and a rheometer with a pasting cell. The texture, porosity, and loaf volume were characterized using a texturometer, ImageJ software, and breadmaking ability, respectively. Finally, a breadmaking aptitude and sensorial bread acceptability were performed. A significant decrease in the content of free amino groups (0.16 to 0.11 and 0.46 to 0.36 mM/mg of protein) and free thiol groups (0.37 to 0.21 and 1.79 to 1.32 mM/mg protein) was observed when 1.0% and 0.5% TG were added to LF and WP, respectively. In apparent viscosity analysis, the action of TG on HC proteins changes their viscosity, while the viscosity of LF is not modified by TG. Results of electrophoresis in PL showed bands of higher molecular weight of different fragments of proteins with 1% TG. Formulation with 59.8, 39.9, 160.8, 6.0, 1.0, and 1.5% of, respectively, QF, BF, CS, LF or WP, TG, and HPMC had the best properties in dough parameters, pasting parameters (lower pasting temperature and higher peak viscosity), best crumb structure, lower crumb hardness and higher loaf volume (2.24 and 2.28 mL/g). All the loaves of bread were acceptable in baking aptitude and general acceptability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breadmaking" title="breadmaking">breadmaking</a>, <a href="https://publications.waset.org/abstracts/search?q=gluten-free" title=" gluten-free"> gluten-free</a>, <a href="https://publications.waset.org/abstracts/search?q=superfoods" title=" superfoods"> superfoods</a>, <a href="https://publications.waset.org/abstracts/search?q=by-products" title=" by-products"> by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a> </p> <a href="https://publications.waset.org/abstracts/131014/combined-effect-of-gluten-free-superfoods-and-by-products-from-ecuador-to-evaluate-the-functional-and-sensory-properties-of-breadmaking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131014.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">133</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">53</span> Evaluation of Water Quality on the Strength of Simple Concrete: Case Study of Wells in Jipijapa, Manabí, Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cesar%20Pino%20Tarrag%C3%B3">Julio Cesar Pino Tarragó</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunia%20Lisbet%20Dom%C3%ADnguez%20G%C3%A1lvez"> Dunia Lisbet Domínguez Gálvez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Alfonso%20Moreno%20Ponce"> Luis Alfonso Moreno Ponce</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhony%20Julio%20Regalado%20Jalca"> Jhony Julio Regalado Jalca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the impact of three distinct types of water on the compressive strength of plain concrete, focusing on samples from wells in Jipijapa, Manabí, Ecuador: Joa water, characterized by high sulfur content; Chade 1 water, with low sulfur content; and Chade 2 water, which is highly brackish. Compressive strength tests were conducted at 7, 14, and 28 days to assess the influence of these water types on the structural integrity of the concrete. The results indicate that both brackish and sulfur-rich water significantly reduces concrete strength, while Chade 1 water, though initially enhancing strength, displays variability in long-term performance. These outcomes underscore the importance of optimizing construction practices in regions like Jipijapa, where potable water is scarce, by exploring sustainable alternatives for using non-potable water, thereby conserving limited water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=plain%20concrete" title=" plain concrete"> plain concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20water" title=" sulfur water"> sulfur water</a>, <a href="https://publications.waset.org/abstracts/search?q=brackish%20water" title=" brackish water"> brackish water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/189221/evaluation-of-water-quality-on-the-strength-of-simple-concrete-case-study-of-wells-in-jipijapa-manabi-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189221.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">35</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">52</span> Sustainable Concepts Applied in the Pre-Columbian Andean Architecture in Southern Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Espinoza-Piedra">Diego Espinoza-Piedra</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Duran"> David Duran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All architectural and land use processes are framed in a cultural, social and geographical context. The present study analyzes the Andean culture before the Spanish conquest in southern Ecuador, in the province of Azuay. This area has been habited for more than 10.000 years. The Canari and the Inca cultures occupied Azuay close to the arrival of the Spanish conquers. The Inca culture was settled in the Andes Mountains. The Canari culture was established in the south of Ecuador, on the actual provinces of Azuay and Canar. In contrast with history and archeology, to the best of our knowledge, their architecture has not yet been studied in this area because of the lack of architectural structures. Consequently, the present research reviewed the land use and culture for architectonic interpretations. The two main architectural objects in these cultures were dwellings and public buildings. In the first case, housing was conceived as temporary. It had to stand as long as its inhabitants lived. Therefore, houses were built when a couple got married. The whole community started the construction through the so-called ‘minga’ or collective work. The construction materials were tree branches, reeds, agave, ground, and straw. So that when their owners aged and then died, this house was easily disarmed and overthrown. Their materials become part of the land for agriculture. Finally, this cycle was repeated indefinitely. In the second case, the buildings, which we can call public, have presented erroneous interpretations. They have been defined as temples. But according to our conclusions, they were places for temporary accommodation, storage of objects and products, and in some special cases, even astronomical observatories. These public buildings were settled along the important road system called ‘Capac-Nam’, currently declared by UNESCO as World Cultural Heritage. The buildings had different scales at regular distances. Also, they were established in special or strategic places, which constituted a system of observatories. These observatories allowed to determine the cycles or calendars (solar or lunar) necessary for the agricultural production, as well as other natural phenomena. Most of the current minimal existence of physical structures in quantity and state of conservation is at the level of foundations or pieces of walls. Therefore, this study was realized after the identification of the history and culture of the inhabitants of this Andean region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andean" title="Andean">Andean</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-Colombian%20architecture" title=" pre-Colombian architecture"> pre-Colombian architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=Southern%20Ecuador" title=" Southern Ecuador"> Southern Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a> </p> <a href="https://publications.waset.org/abstracts/93910/sustainable-concepts-applied-in-the-pre-columbian-andean-architecture-in-southern-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93910.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">127</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">51</span> Study and Conservation of Cultural and Natural Heritages with the Use of Laser Scanner and Processing System for 3D Modeling Spatial Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julia%20Desiree%20Velastegui%20Caceres">Julia Desiree Velastegui Caceres</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Alejandro%20Velastegui%20Caceres"> Luis Alejandro Velastegui Caceres</a>, <a href="https://publications.waset.org/abstracts/search?q=Oswaldo%20Padilla"> Oswaldo Padilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Kirby"> Eduardo Kirby</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Guerrero"> Francisco Guerrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Theofilos%20%20Toulkeridis"> Theofilos Toulkeridis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is fundamental to conserve sites of natural and cultural heritage with any available technique or existing methodology of preservation in order to sustain them for the following generations. We propose a further skill to protect the actual view of such sites, in which with high technology instrumentation we are able to digitally preserve natural and cultural heritages applied in Ecuador. In this project the use of laser technology is presented for three-dimensional models, with high accuracy in a relatively short period of time. In Ecuador so far, there are not any records on the use and processing of data obtained by this new technological trend. The importance of the project is the description of the methodology of the laser scanner system using the Faro Laser Scanner Focus 3D 120, the method for 3D modeling of geospatial data and the development of virtual environments in the areas of Cultural and Natural Heritage. In order to inform users this trend in technology in which three-dimensional models are generated, the use of such tools has been developed to be able to be displayed in all kinds of digitally formats. The results of the obtained 3D models allows to demonstrate that this technology is extremely useful in these areas, but also indicating that each data campaign needs an individual slightly different proceeding starting with the data capture and processing to obtain finally the chosen virtual environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20scanner%20system" title="laser scanner system">laser scanner system</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20model" title=" 3D model"> 3D model</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title=" cultural heritage"> cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20heritage" title=" natural heritage"> natural heritage</a> </p> <a href="https://publications.waset.org/abstracts/58508/study-and-conservation-of-cultural-and-natural-heritages-with-the-use-of-laser-scanner-and-processing-system-for-3d-modeling-spatial-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58508.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">306</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">50</span> A Multi-Layer Based Architecture for the Development of an Open Source CAD/CAM Integration Virtual Platform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alvaro%20Aguinaga">Alvaro Aguinaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Avila"> Carlos Avila</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Cando"> Edgar Cando </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article proposes a n-layer architecture, with a web client as a front-end, for the development of a virtual platform for process simulation on CNC machines. This Open-Source platform includes a CAD-CAM interface drawing primitives, and then used to furnish a CNC program that triggers a touch-screen virtual simulator. The objectives of this project are twofold. First one is an educational component that fosters new alternatives for the CAD-CAM/CNC learning process in undergrad and grade schools and technical and technological institutes emphasizing in the development of critical skills, discussion and collaborative work. The second objective puts together a research and technological component that will take the state of the art in CAD-CAM integration to a new level with the development of optimal algorithms and virtual platforms, on-line availability, that will pave the way for the long-term goal of this project, that is, to have a visible and active graduate school in Ecuador and a world wide Open-Innovation community in the area of CAD-CAM integration and operation of CNC machinery. The virtual platform, developed as a part of this study: (1) delivers improved training process of students, (2) creates a multidisciplinary team and a collaborative work space that will push the new generation of students to face future technological challenges, (3) implements industry standards for CAD/CAM, (4) presents a platform for the development of industrial applications.

These projects are part of the portfolio sent to the United Nations Framework on Climate Change (UNFCCC) as a commitment to reduce greenhouse gas emissions (GHG) in the established national determined contribution (NDC). In this sense, the Ecuadorian Organic Energy Efficiency Law (LOEE) published in 2019 promotes E-mobility as one of the main milestones. In fact, it states that the new vehicles for urban and interurban usage must be E-buses since 2025. As a result, and for a successful implementation of this technological change in a national context, it is important to deploy land surveys focused on technical and geographical areas to keep the quality of services in both the electricity and transport sectors. Therefore, this research presents a technological and energy comparison between a conventional diesel bus and its equivalent E-bus. Both vehicles fulfill all the technical requirements to ride in the study-case city, which is Ambato in the province of Tungurahua-Ecuador. In addition, the analysis includes the development of a model for the energy estimation of both technologies that are especially applied in a highland city such as Ambato. The altimetry of the most important bus routes in the city varies from 2557 to 3200 m.a.s.l., respectively, for the lowest and highest points. These operation conditions provide a grade of novelty to this paper. Complementary, the technical specifications of diesel buses are defined following the common features of buses registered in Ambato. On the other hand, the specifications for E-buses come from the most common units introduced in Latin America because there is not enough evidence in similar cities at the moment. The achieved results will be good input data for decision-makers since electric demand forecast, energy savings, costs, and greenhouse gases emissions are computed. Indeed, GHG is important because it allows reporting the transparency framework that it is part of the Paris Agreement. Finally, the presented results correspond to stage I of the called project “Analysis and Prospective of Electromobility in Ecuador and Energy Mix towards 2030” supported by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20altitude%20cities" title="high altitude cities">high altitude cities</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20planning" title=" energy planning"> energy planning</a>, <a href="https://publications.waset.org/abstracts/search?q=NDC" title=" NDC"> NDC</a>, <a href="https://publications.waset.org/abstracts/search?q=e-buses" title=" e-buses"> e-buses</a>, <a href="https://publications.waset.org/abstracts/search?q=e-mobility" title=" e-mobility"> e-mobility</a> </p> <a href="https://publications.waset.org/abstracts/142982/simulation-of-technological-energy-and-ghg-comparison-between-a-conventional-diesel-bus-and-e-bus-feasibility-to-promote-e-bus-change-in-high-lands-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142982.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">151</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">48</span> Breastfeeding Experiences of Nutritionist who are Mothers in Quito- Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Jose%20Mendoza%20Gordillo">Maria Jose Mendoza Gordillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Research regarding breastfeeding is devoted to how essential breastfeeding is to guarantee wellbeing for the mother and the baby from a medical standpoint relegating the cultural, material and social barriers for breastfeeding. Consequently, worldwide breastfeeding rates are low, and Ecuador is not the exception, especially among working mothers. Worldwide, health care providers have low rates of breastfeeding due to several barriers to lactation, such as the work schedule, a lack of private places for pumping while at work, and negative emotions. Goals and Methods: This study aimed to explore how do Ecuadorian women embrace their identities as nutritionists and mothers within their breastfeeding experience. The primary data come from 20 synchronous semi-structured interviews, which follow a topic guide. The interviews were recorded and transcribed verbatim. The data analysis followed the Phronetic Iterative Approach. Results: Women shifted the preconceived idea of the ideal breastfeeding that came from the medicalized discourse of breastfeeding, and that was constructed in their training as nutritionists. Although these women believe that breast milk and breastfeeding is the best way to feed a baby, the internalized ideal of breastfeeding shifted through the experience of motherhood. When these women developed their identity as mothers, they understood that the ideal breastfeeding is different from the medicalized discourse. Although they have that clash between the ideal and the external reality, they continued breastfeeding their babies and those experiences made them improve their professional practice. Conclusions: The narratives that women shared illustrate how complex it was to manage the different roles and identities that they wanted to fulfill to keep their identity of a good mother who breastfeeds her baby and, at the same time, a good healthcare provider identity. The process of breastfeeding for this group of women who are mothers and healthcare professionals appears to be a unique relational and identity negotiation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breastfeeding" title="breastfeeding">breastfeeding</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritionist" title=" nutritionist"> nutritionist</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative" title=" qualitative"> qualitative</a> </p> <a href="https://publications.waset.org/abstracts/143304/breastfeeding-experiences-of-nutritionist-who-are-mothers-in-quito-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143304.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">179</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">47</span> Food Composition Tables Used as an Instrument to Estimate the Nutrient Ingest in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ortiz%20M.%20Roc%C3%ADo">Ortiz M.

A main instrument commonly used to build those tools is the food composition tables (FCT). Despite the importance of FCT, there are many error sources and variability factors that can be presented on building those tables and can lead to an under or over estimation of ingest of nutrients of a population. This work identified different food composition tables used as an instrument to estimate the nutrient ingest in Ecuador.The collection of data for choosing FCT was made through key informants –self completed questionnaires-, supplemented with institutional web research. A questionnaire with general variables (origin, year of edition, etc) and methodological variables (method of elaboration, information of the table, etc) was passed to the identified FCT. Those variables were defined based on an extensive literature review. A descriptive analysis of content was performed. Ten printed tables and three databases were reported which were all indistinctly treated as food composition tables. We managed to get information from 69% of the references. Several informants referred to printed documents that were not accessible. In addition, searching the internet was not successful. Of the 9 final tables, n=8 are from Latin America, and, n= 5 of these were constructed by indirect method (collection of already published data) having as a main source of information a database from the United States department of agriculture USDA. One FCT was constructed by using direct method (bromatological analysis) and has its origin in Ecuador. The 100% of the tables made a clear distinction of the food and its method of cooking, 88% of FCT expressed values of nutrients per 100g of edible portion, 77% gave precise additional information about the use of the table, and 55% presented all the macro and micro nutrients on a detailed way. The more complete FCT were: INCAP (Central America), Composition of foods (Mexico). The more referred table was: Ecuadorian food composition table of 1965 (70%). The indirect method was used for most tables within this study. However, this method has the disadvantage that it generates less reliable food composition tables because foods show variations in composition. Therefore, a database cannot accurately predict the composition of any isolated sample of a food product.In conclusion, analyzing the pros and cons, and, despite being a FCT elaborated by using an indirect method, it is considered appropriate to work with the FCT of INCAP Central America, given the proximity to our country and a food items list that is very similar to ours. Also, it is imperative to have as a reference the table of composition for Ecuadorian food, which, although is not updated, was constructed using the direct method with Ecuadorian foods. Hence, both tables will be used to elaborate a questionnaire with the purpose of assessing the food consumption of the Ecuadorian population. In case of having disparate values, we will proceed by taking just the INCAP values because this is an updated table. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ecuadorian%20food%20composition%20tables" title="Ecuadorian food composition tables">Ecuadorian food composition tables</a>, <a href="https://publications.waset.org/abstracts/search?q=FCT%20elaborated%20by%20direct%20method" title="FCT elaborated by direct method">FCT elaborated by direct method</a>, <a href="https://publications.waset.org/abstracts/search?q=ingest%20of%20nutrients%20of%20Ecuadorians" title=" ingest of nutrients of Ecuadorians"> ingest of nutrients of Ecuadorians</a>, <a href="https://publications.waset.org/abstracts/search?q=Latin%20America%20food%20composition%20tables" title=" Latin America food composition tables "> Latin America food composition tables </a> </p> <a href="https://publications.waset.org/abstracts/28095/food-composition-tables-used-as-an-instrument-to-estimate-the-nutrient-ingest-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28095.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">432</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">46</span> Positivity of Pathogenic Leptospira in Pigs from Rural Communities on the Coast of Ecuador </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Veronica%20Barragan">Veronica Barragan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ligia%20Luna"> Ligia Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Patricia%20Zambrano"> Maria Patricia Zambrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20%20Bulnes"> Carlos Bulnes</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Diaz"> Eduardo Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Talima%20%20Pearson"> Talima Pearson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leptospirosis impacts animal production and is responsible for important economic losses in the pig industry. Infection is associated with reproductive failures that lead to abortions, stillbirth, and perinatal mortality. The leptospira serogroups that have been traditionally linked to disease in pigs are Pomona, Australis, and Tarassovi. Unfortunately, knowledge about pig leptospirosis is biased towards infection in large-scale commercial farms from developed countries, where exposure is usually limited to host-specific serotypes. The aim of our study is to describe leptospirosis in pigs from rural communities located in the coast of Ecuador-South America, where leptospirosis is endemic. A particularity of these pigs is that, because they are usually raised in the backyard of their owner’s houses, exposure to other leptospira excreted by other animals is likely to occur. Therefore, we collected 420 kidney samples from pigs sacrificed at a local slaughterhouse, and Leptospira positivity was tested in all samples by amplifying the Lipl32 gen. Our results show pathogenic Leptospira positivity in 19.3% (81/420) of pigs. Microaglutination test was performed in 60 PCR positive samples with titers >1:100 in 17 pigs, titers of 1:50 in 28 pigs, and no MAT titers in 15 pigs even though Leptospira DNA was found in their kidneys. Interestingly, reacting serovars were very diverse, with 18.3% of pig sera reacting with two or more serovars. Additionally, serovar Canicola was found in 16.7% of pigs followed by Tarassovi (10%), Australis (6.7%), Pyogenes (5%), Icterohaemorrhageae (1.7%), and Grippotyphosa (1.7%). It is also important to highlight that most of the analyzed animals came from small-scale farms where pigs may be exposed to the pathogen by exposure to other domestic and peridomestic animals such as rats, dogs, horses, donkeys, and even wildlife. This would explain the finding of non-pig adapted Leptospira serovars such as Canicola, which is commonly reported in dogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leptospira" title="Leptospira">Leptospira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lipl32" title=" Lipl32"> Lipl32</a>, <a href="https://publications.waset.org/abstracts/search?q=peridomestic" title=" peridomestic"> peridomestic</a>, <a href="https://publications.waset.org/abstracts/search?q=pig" title=" pig"> pig</a>, <a href="https://publications.waset.org/abstracts/search?q=serovar" title=" serovar"> serovar</a> </p> <a href="https://publications.waset.org/abstracts/124826/positivity-of-pathogenic-leptospira-in-pigs-from-rural-communities-on-the-coast-of-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124826.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">138</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">45</span> Smart Cities, Morphology of the Uncertain: A Study on Development Processes Applied by Amazonian Cities in Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Coloma">Leonardo Coloma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world changes constantly, every second its properties vary due either natural factors or human intervention. As the most intelligent creatures on the planet, human beings have transformed the environment and paradoxically –have allowed ‘mother nature’ to lose species, accelerate the processes of climate change, the deterioration of the ozone layer, among others. The rapid population growth, the procurement, administration and distribution of resources, waste management, and technological advances are some of the factors that boost urban sprawl whose gray stain extends over the territory, facing challenges such as pollution, overpopulation and scarcity of resources. In Ecuador, these problems are added to the social, cultural, economic and political anomalies that have historically affected it. This fact can represent a greater delay when trying to solve global problems, without having paid attention to local inconveniences –smaller ones, but ones that could be the key to project smart solutions on bigger ones. This research aims to highlight the main characteristics of the development models adopted by two Amazonian cities, and analyze the impact of such urban growth on society; to finally define the parameters that would allow the development of an intelligent city in Ecuador, prepared for the challenges of the XXI Century. Contrasts in the climate, temperature, and landscape of Ecuadorian cities are fused with the cultural diversity of its people, generating a multiplicity of nuances of an indecipherable wealth. However, we strive to apply development models that do not recognize that wealth, not understanding them and ignoring that their proposals will vary according to where they are applied. Urban plans seem to take a bit of each of the new theories and proposals of development, which, in the encounter with the informal growth of cities, with those excluded and ‘isolated’ societies, generate absurd morphologies - where the uncertain becomes tangible. The desire to project smart cities is ever growing, but it is important to consider that this concept does not only have to do with the use of information and communication technologies. Its success is achieved when advances in science and technology allow the establishment of a better relationship between people and their context (natural and built). As a research methodology, urban analysis through mappings, diagrams and geographical studies, as well as the identification of sensorial elements when living the city, will make evident the shortcomings of the urban models adopted by certain populations of the Ecuadorian Amazon. Following the vision of previous investigations started since 2014 as part of ‘Centro de Acciones Urbanas,’ the results of this study will encourage the dialogue between the city (as a physical fact) and those who ‘make the city’ (people as its main actors). This research will allow the development of workshops and meetings with different professionals, organizations and individuals in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latin%20American%20cities" title="Latin American cities">Latin American cities</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20development" title=" urban development"> urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20morphology" title=" urban morphology"> urban morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20sprawl" title=" urban sprawl"> urban sprawl</a> </p> <a href="https://publications.waset.org/abstracts/89610/smart-cities-morphology-of-the-uncertain-a-study-on-development-processes-applied-by-amazonian-cities-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89610.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</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. In addition, veliger stage was registered at 20 h post-fertilization with individual average length of 82 ± 6 µm. Umboned larvae appeared at day 8 post-fertilization, with individual average length of 148 ± 6 µm. These pioneering results worldwide can strengthen the local conservation process of the overexploited P. multicostata and to encourage its production for commercial purposes. <p class="card-text"><strong>Keywords:</strong> <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=Periglypta%20multicostata" title=" Periglypta multicostata"> Periglypta multicostata</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/103303/spawning-induction-and-early-larval-development-of-the-giant-reef-clam-periglypta-multicostata-sowerby-1835-under-controlled-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103303.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">136</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">43</span> The Ecuador Healthy Food Environment Policy Index (Food-EPI)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Escand%C3%B3n">Samuel Escandón</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20J.%20Pe%C3%B1aherrera-V%C3%A9lez"> María J.

In Ecuador, 35.4% of 5- to 11-year-olds and 29.6% of 12- to 19-year-olds are overweight or obese. Globally, unhealthy food environments characterized by high consumption of processed/ultra-processed food and rapid urbanization are highly related to the increasing nutrition-related non-communicable diseases. The evidence shows that in low- and middle-income countries (LMICs), fiscal policies and regulatory measures significantly reduce unhealthy food environments, achieving substantial advances in health. However, in some LMICs, little is known about the impact of governments' action to implement healthy food-environment policies. This study aimed to generate evidence on the state of implementation of public policy focused on food environments for the prevention of overweight and obesity in children and adolescents in Ecuador compared to global best practices and to target key recommendations for reinforcing the current strategies. After adapting the INFORMAS' Healthy Food Environment Policy Index (Food‐EPI) to the Ecuadorian context, the Policy and Infrastructure support components were assessed. Individual online interviews were performed using fifty-one indicators to analyze the level of implementation of policies directly or indirectly related to preventing overweight and obesity in children and adolescents compared to international best practices. Additionally, a participatory workshop was conducted to identify the critical indicators and generate recommendations to reinforce or improve the political action around them. In total, 17 government and non-government experts were consulted. From 51 assessed indicators, only the one corresponding to the nutritional information and ingredients labelling registered an implementation level higher than 60% (67%) compared to the best international practices. Among the 17 indicators determined as priorities by the participants, those corresponding to the provision of local products in school meals and the limitation of unhealthy-products promotion in traditional and digital media had the lowest level of implementation (34% and 11%, respectively) compared to global best practices. The participants identified more barriers (e.g., lack of continuity of effective policies across government administrations) than facilitators (e.g., growing interest from the Ministry of Environment because of the eating-behavior environmental impact) for Ecuador to move closer to the best international practices. Finally, within the participants' recommendations, we highlight the need for policy-evaluation systems, information transparency on the impact of the policies, transformation of successful strategies into laws or regulations to make them mandatory, and regulation of power and influence from the food industry (conflicts of interest). Actions focused on promoting a more active role of society in the stages of policy formation and achieving more articulated actions between the different government levels/institutions for implementing the policy are necessary to generate a noteworthy impact on preventing overweight and obesity in children and adolescents. Including systems for internal evaluation of existing strategies to strengthen successful actions, create policies to fill existing gaps and reform policies that do not generate significant impact should be a priority for the Ecuadorian government to improve the country's food environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20and%20adolescents" title="children and adolescents">children and adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=food-EPI" title=" food-EPI"> food-EPI</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20policies" title=" food policies"> food policies</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20food%20environment" title=" healthy food environment"> healthy food environment</a> </p> <a href="https://publications.waset.org/abstracts/172816/the-ecuador-healthy-food-environment-policy-index-food-epi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172816.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">42</span> Optimization of the Jatropha curcas Supply Chain as a Criteria for the Implementation of Future Collection Points in Rural Areas of Manabi-Ecuador </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20G.%20German">Boris G.

Nonetheless, such development is energy-intensive and requires thousands of gallons of diesel each year for thermoelectric electricity generation. The needed transport of fossil fuels from the continent has generated oil spillages and affectations to the fragile ecosystem of the islands. The Zero Fossil Fuels initiative for The Galapagos proposed by the Ecuadorian government as an alternative to reduce the use of fossil fuels in the islands, considers the replacement of diesel in thermoelectric generators, by Jatropha curcas vegetable oil. However, the Jatropha oil supply cannot entirely cover yet the demand for electricity generation in Galapagos. Within this context, the present work aims to provide an optimization model that can be used as a selection criterion for approving new Jatropha Curcas collection points in rural areas of Manabi-Ecuador. For this purpose, existing Jatropha collection points in Manabi were grouped under three regions: north (7 collection points), center (4 collection points) and south (9 collection points). Field work was carried out in every region in order to characterize the collection points, to establish local Jatropha supply and to determine transportation costs. Data collection was complemented using GIS software and an objective function was defined in order to determine the profit associated to Jatropha oil production. The market price of both Jatropha oil and residual cake, were considered for the total revenue; whereas Jatropha price, transportation and oil extraction costs were considered for the total cost. The tonnes of Jatropha fruit and seed, transported from collection points to the extraction plant, were considered as variables. The maximum and minimum amount of the collected Jatropha from each region constrained the optimization problem. The supply chain was optimized using linear programming in order to maximize the profits. Finally, a sensitivity analysis was performed in order to find a profit-based criterion for the acceptance of future collection points in Manabi. The maximum profit reached a value of $ 4,616.93 per year, which represented a total Jatropha collection of 62.3 tonnes Jatropha per year. The northern region of Manabi had the biggest collection share (69%), followed by the southern region (17%). The criteria for accepting new Jatropha collection points in the rural areas of Manabi can be defined by the current maximum profit of the zone and by the variation in the profit when collection points are removed one at a time. The definition of new feasible collection points plays a key role in the supply chain associated to Jatropha oil production. Therefore, a mathematical model that assists decision makers in establishing new collection points while assuring profitability, contributes to guarantee a continued Jatropha oil supply for Galapagos and a sustained economic growth in the rural areas of Ecuador. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collection%20points" title="collection points">collection points</a>, <a href="https://publications.waset.org/abstracts/search?q=Jatropha%20curcas" title=" Jatropha curcas"> Jatropha curcas</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/34611/optimization-of-the-jatropha-curcas-supply-chain-as-a-criteria-for-the-implementation-of-future-collection-points-in-rural-areas-of-manabi-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34611.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">433</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">41</span> OAS and Interstate Dispute Resolution at the Beginning of the 21st Century: General Pattern and Peculiarities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Jeifets">Victor Jeifets</a>, <a href="https://publications.waset.org/abstracts/search?q=Liliia%20Khadorich"> Liliia Khadorich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper describes the OAS role in dispute resolution.

In this paper, we use the suburb of La Villaflora in the city of Quito, Ecuador as our case study. We first propose a system of indicators as a tool to characterize and quantify the historic value of a geographic area. Then, we apply these indicators to the suburb of La Villaflora and use Network Theory to understand and propose actions. <p class="card-text"><strong>Keywords:</strong> <a
