These third parties may take the form of consultancy firms, guilds or professional advisors that do not perform an economic activity in the market where the collusion takes place. This paper takes a look into how national competition authorities and national legislators have dealt with the emergence of the cartels’ facilitators in Latin America. Following the practice of other jurisdictions such as United States (Toys R' Us, Apple), European Union (AC Treuhand), United Kingdom (Replica Kits, Hasbro) and Spain (Urban, Snap-On), some countries (e.g. Argentina, Chile) in Latin America have started to conduct investigations and find antitrust liability in cartels’ facilitators for helping others to violate their national competition laws. Some countries (e.g. Peru and Colombia) have also amended their legislation to amplify the subjective scope of application in order to include cartels’ facilitators. The Latin American case is one of special relevance because public officials are often prone to promote or indulge agreements between competitors in sectors of political interest. A broad definition of cartels’ facilitator, consequently, could lead to the prosecution of punishment of public officials that may hinder the competitive process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticompetitive%20practices" title="anticompetitive practices">anticompetitive practices</a>, <a href="https://publications.waset.org/abstracts/search?q=cartel" title=" cartel"> cartel</a>, <a href="https://publications.waset.org/abstracts/search?q=collusion" title=" collusion"> collusion</a>, <a href="https://publications.waset.org/abstracts/search?q=competition" title=" competition"> competition</a>, <a href="https://publications.waset.org/abstracts/search?q=facilitator" title=" facilitator"> facilitator</a>, <a href="https://publications.waset.org/abstracts/search?q=hub%20and%20spoke" title=" hub and spoke"> hub and spoke</a> </p> <a href="https://publications.waset.org/abstracts/105072/cartels-little-helpers-a-comparative-study-of-the-case-law-regarding-the-facilitators-of-collusion-in-latin-america-competition-law-and-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105072.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">165</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">121</span> Effect of Outliers in Assessing Significant Wave Heights Through a Time-Dependent GEV Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Calder%C3%B3n-Vega">F.

In this study, some extremely large wave heights recorded in NOAA buoys (National Data Buoy Center, noaa.gov) are used to investigate their effect in the prediction of future wave heights associated with given return periods. Extreme waves are predicted through a time-dependent model based on the so-called generalized extreme value distribution. It is found that the outliers do affect the estimated wave heights. It is concluded that a detailed inspection of outliers is envisaged to determine whether they are real recorded values since this will impact defining design wave heights for coastal protection purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GEV%20model" title="GEV model">GEV model</a>, <a href="https://publications.waset.org/abstracts/search?q=non-stationary" title=" non-stationary"> non-stationary</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonality" title=" seasonality"> seasonality</a>, <a href="https://publications.waset.org/abstracts/search?q=outliers" title=" outliers"> outliers</a> </p> <a href="https://publications.waset.org/abstracts/147991/effect-of-outliers-in-assessing-significant-wave-heights-through-a-time-dependent-gev-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147991.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">120</span> Internet of Things Applications on Supply Chain Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Cort%C3%A9s">Beatriz Cortés</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20Boza"> Andrés Boza</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20P%C3%A9rez"> David Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Llanos%20Cuenca"> Llanos Cuenca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of Things (IoT) field is been applied in industries with different purposes.

The people in charge of answering the questionnaires are the daycare assistants. Its application presents a series of previous activities with which daycare assistants are familiar (dance, games, oral narration and breakfast), which are executed with the children and then answer a questionnaire with dichotomous questions "Yes/No" in approximately 3 minutes per child. The instrument was developed with the participation of nurseries according to the protocols of the creation of psychometric instruments of the Classical Test Theory having as a gold standard ADOS-2 Modules T and 1. The results of the investigation show that the use of ASQ-DAT combined with the application of M-CHAT / RF provides more information about the risk of ASD in young children, which allows improvements in the screening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title="diagnosis">diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=autism" title=" autism"> autism</a>, <a href="https://publications.waset.org/abstracts/search?q=daycare" title=" daycare"> daycare</a> </p> <a href="https://publications.waset.org/abstracts/92545/autism-screening-questionnaire-for-daycare-attendees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92545.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">219</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">118</span> Understanding and Enhancing Ecotourism Opportunities through Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Iakovoglou">V.

Through these activities species and habitats are maintained and typically, underdeveloped regions are emphasized. Ecotourism provides a great alternative, especially for rural and undeveloped area. At the same time, despite its many benefits, it also poses many risks for the naturally protected areas. If ecotourism is practiced improperly degradation and irreversible damages could be the unwanted result. In addition, the lack of MSc programs in the field of Ecotourism in Europe makes it a necessity to be developed. Such an MSc program is being implemented with the lead partner the Technical University of Madrid. The entire partnership has six Universities, seven SMEs and one National Park from seven different countries all over Europe. The MSc will have 10 educational modules that will be available online and will prepare professionals that will be able to implement ecotourism in a sustainable way. Only through awareness and education a sustainable ecotourism will be achieved in the protected areas of Europe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ERASMUS" title="ERASMUS">ERASMUS</a>, <a href="https://publications.waset.org/abstracts/search?q=MSc%20program" title=" MSc program"> MSc program</a>, <a href="https://publications.waset.org/abstracts/search?q=protected%20Areas" title=" protected Areas"> protected Areas</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/33488/understanding-and-enhancing-ecotourism-opportunities-through-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33488.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">117</span> Experiential Learning in an Earthquake Engineering Course Using Online Tools and Shake Table Exercises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andres%20Winston%20Oreta">Andres Winston Oreta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Experiential Learning (ELE) is a strategy for enhancing the teaching and learning of courses especially in civil engineering.

The magnetic materials presented in this project belong to a group known as Heusler alloys. These compounds are characterized by a strong coupling between their structure and magnetic properties. Usually, a change in one of them can alter the other, which implies changes in other electronic or structural properties, such as, shape magnetic memory response or the magnetocaloric effect. Those properties and its dependence with external fields make these materials interesting, both from a fundamental point of view, as well as on their different possible applications. In this work, first principles and Monte Carlo simulations have been used to calculate exchange couplings and magnetic properties as a function of an applied magnetic field on Heusler alloys. As a result, we found a large dependence of the magnetic susceptibility, entropy and heat capacity, indicating that the magnetic field can be used in experiments to trigger particular magnetic properties in materials, which are necessary to develop solid-state refrigeration devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferromagnetic%20materials" title="ferromagnetic materials">ferromagnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetocaloric%20effect" title=" magnetocaloric effect"> magnetocaloric effect</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20design" title=" materials design"> materials design</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20refrigeration" title=" solid state refrigeration"> solid state refrigeration</a> </p> <a href="https://publications.waset.org/abstracts/108024/design-of-advanced-materials-for-alternative-cooling-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108024.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">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">113</span> Batteryless DCM Boost Converter for Kinetic Energy Harvesting Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20Gomez-Casseres">Andrés Gomez-Casseres</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20Contreras"> Rubén Contreras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a bidirectional boost converter operated in Discontinuous Conduction Mode (DCM) is presented as a suitable power conditioning circuit for tuning of kinetic energy harvesters without the need of a battery.

The converter, along with the control system, is validated through SPICE simulations using the LTspice tool. The converter model and the controller transfer functions are derived.

We determined the spatial impact of urban facilities on sustainable travel patterns through the statistical analysis, data visualisation, and weighted regression models. The results show a need to diversify land use in more than 60% of the communes, although in 85% of the communes, accessibility to public spaces is guaranteed. The findings also suggest improving access to early education facilities, as only 26% of the communes meet the sustainability standard, negatively impacting travel in sustainable modes. It is also observed that the level of access to urban facilities generates spatial heterogeneity in the city, which negatively affects travel patterns in terms of time over 60 minutes and modes of travel in private vehicles. The results obtained allow us to identify opportunities for public policy intervention to promote and adopt sustainable mobility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20use" title="land use">land use</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20sustainability" title=" urban sustainability"> urban sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20patterns" title=" travel patterns"> travel patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20heterogeneity" title=" spatial heterogeneity"> spatial heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=GWR%20model" title=" GWR model"> GWR model</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20mobility" title=" sustainable mobility"> sustainable mobility</a> </p> <a href="https://publications.waset.org/abstracts/171732/urban-sustainability-and-sustainable-mobility-lessons-learned-from-the-case-of-chile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171732.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">81</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">111</span> Economic and Ecological Implications in Agricultural Production Within the Strong and Weak Sustainability Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Quintero%20Angel">Mauricio Quintero Angel</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20A.%20Duque%20Nivia"> Andrés A.

Under each approach the economic and ecological implications of the palm oil production and especially the implications for crop management are described. The crop production under the weak sustainability implies plantations, intensive use of agrochemicals and the inclusion of new areas of cultivation as the market grows. Under the strong sustainability the production system is limited by the productive vocation of the ecosystem, so that new approaches and creativity for making viable the nature conservancy and the business development are require. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20palm" title=" oil palm"> oil palm</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20sustainability" title=" strong sustainability"> strong sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20sustainability" title=" weak sustainability "> weak sustainability </a> </p> <a href="https://publications.waset.org/abstracts/29377/economic-and-ecological-implications-in-agricultural-production-within-the-strong-and-weak-sustainability-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29377.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">431</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">110</span> Analysis of Fertilizer Effect in the Tilapia Growth of Mozambique (Oreochromis mossambicus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%A9rgio%20Afonso%20Mulema">Sérgio Afonso Mulema</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20Carri%C3%B3n%20Garc%C3%ADa"> Andrés Carrión García</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicente%20Ernesto"> Vicente Ernesto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses the effect of fertilizer (organic and inorganic) in the growth of tilapia. An experiment was implemented in the Aquapesca Company of Mozambique; there were considered four different treatments. Each type of fertilizer was applied in two of these treatments; a feed was supplied to the third treatment, and the fourth was taken as control. The weight and length of the tilapia were used as the growth parameters, and to measure the water quality, the physical-chemical parameters were registered. The results show that the weight and length were different for tilapias cultivated in different treatments. These differences were evidenced mainly by organic and feed treatments, where there was the largest and smallest value of these parameters, respectively. In order to prove that these differences were caused only by applied treatment without interference for the aquatic environment, a Fisher discriminant analysis was applied, which confirmed that the treatments were exposed to the same environment condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fertilizer" title="fertilizer">fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=tilapia" title=" tilapia"> tilapia</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20methods" title=" statistical methods"> statistical methods</a> </p> <a href="https://publications.waset.org/abstracts/89898/analysis-of-fertilizer-effect-in-the-tilapia-growth-of-mozambique-oreochromis-mossambicus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89898.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">229</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">109</span> Economic Development and New Challenges: Biomass Energy and Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabricia%20G.%20F.%20S.%20Rossato">Fabricia G.

The system is called MIS (Musical Inspiration Simulator). The MIS system is inspired by media to which human beings are exposed daily (visual, textual, or auditory) to create new musical compositions based on the emotions detected in said media. After building the system we carried out a series of evaluations with volunteer users who used MIS to compose music based on images, texts, and audio files. The volunteers were asked to judge the harmoniousness and innovation in the system's compositions. An analysis of the results points to the difficulty of computational analysis of the characteristics of the media to which we are exposed daily, as human emotions have a subjective character.

Due to their operational characteristics, they can generate time-varying harmonic and inter-harmonic distortions. For this reason, the application of methods of measurement based on traditional Fourier analysis, as proposed by IEC 61000-4-7, can provide inaccurate results. Considering the aspects mentioned herein, came the idea of the development of this work which aims to present the results of a comparative evaluation between a methodology arising from the combination of the Prony method with the Kalman filter and another method based on the IEC 61000-4-30 and IEC 61000-4-7 standards.

Flexible test-benches able to independently manage groups of crops are key for investigating efficient fertigation practices through experimentation. These test-benches must be able to provide nutrient solution (NS) in a precise, uniform and repeatable way in order to effectively implement and compare different fertigation strategies. This article describes a distribution module for investigating fertigation practices able to control the fertigation dose and frequency. The proposed solution is characterized in terms of precision, uniformity and repeatability since these parameters are fundamental in the implementation of effective experiments for the investigation of fertigation practices.

In these games, the negotiation has two stages. In the first stage, players can only negotiate with others with whom they are compatible. In the second stage, the grand coalition will be formed. We introduce a value for these games. Given a game with a priori incompatibility (N,v,g), we consider the family of coalitions without incompatibility relations among their players. This family is a normal set system or coalition configuration Ig. Therefore, we can assign to each game with a priori incompatibilities (N,v,g) a game with coalition configuration (N,v, Ig). Now, in order to obtain a payoff vector for (N,v,g), it suffices to calculate a payoff vector for (N,v, Ig). To this end, we apply a value for games with coalition configuration. In our case, we will use the dual configuration value, which has been studied in the literature. With this method, we obtain a value for games with a priori incompatibilities, which is called the Owen value for a priori incompatibilities. We provide a characterization of this value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative%20game" title="cooperative game">cooperative game</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20with%20coalition%20configuration" title=" game with coalition configuration"> game with coalition configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=graph" title=" graph"> graph</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20set" title=" independent set"> independent set</a>, <a href="https://publications.waset.org/abstracts/search?q=Owen%20value" title=" Owen value"> Owen value</a>, <a href="https://publications.waset.org/abstracts/search?q=Shapley%20value" title=" Shapley value"> Shapley value</a> </p> <a href="https://publications.waset.org/abstracts/112957/an-owen-value-for-cooperative-games-with-pairwise-a-priori-incompatibilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112957.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">131</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">104</span> Regionalization of IDF Curves, by Interpolating Intensity and Adjustment Parameters - Application to Boyacá, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Mauricio%20Acosta">Pedro Mauricio Acosta</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Andr%C3%A9s%20Caro"> Carlos Andrés Caro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents the regionalization of IDF curves for the department of Boyacá, Colombia, which comprises 16 towns, including the provincial capital, Tunja.

In the case of the regionalization maps parameters associated with each parameter were performed last. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intensity%20duration" title="intensity duration">intensity duration</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20curves" title=" frequency curves"> frequency curves</a>, <a href="https://publications.waset.org/abstracts/search?q=regionalization" title=" regionalization"> regionalization</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrology" title=" hydrology"> hydrology</a> </p> <a href="https://publications.waset.org/abstracts/33615/regionalization-of-idf-curves-by-interpolating-intensity-and-adjustment-parameters-application-to-boyaca-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33615.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">325</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">103</span> Generalized Additive Model Approach for the Chilean Hake Population in a Bio-Economic Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Selin%20Guney">Selin Guney</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Riquelme"> Andres Riquelme</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The traditional bio-economic method for fisheries modeling uses some estimate of the growth parameters and the system carrying capacity from a biological model for the population dynamics (usually a logistic population growth model) which is then analyzed as a traditional production function. The stock dynamic is transformed into a revenue function and then compared with the extraction costs to estimate the maximum economic yield. In this paper, the logistic population growth model for the population is combined with a forecast of the abundance and location of the stock by using a generalized additive model approach. The paper focuses on the Chilean hake population. This method allows for the incorporation of climatic variables and the interaction with other marine species, which in turn will increase the reliability of the estimates and generate better extraction paths for different conservation objectives, such as the maximum biological yield or the maximum economic yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-economic" title="bio-economic">bio-economic</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries" title=" fisheries"> fisheries</a>, <a href="https://publications.waset.org/abstracts/search?q=GAM" title=" GAM"> GAM</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a> </p> <a href="https://publications.waset.org/abstracts/59045/generalized-additive-model-approach-for-the-chilean-hake-population-in-a-bio-economic-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59045.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">252</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">102</span> Optimization Model for Support Decision for Maximizing Production of Mixed Fresh Fruit Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20I.%20%C3%81vila">Andrés I.

To get an efficient supply chain model, several functions should be considered to get a complete simulation of several operational units. We consider a linear programming model to help farmers to decide if it is convenient to choose what area should be planted for three kinds of export fruits considering their future investment. We consider area, investment, water, productivity minimal unit, and harvest restrictions to develop a monthly based model to compute the average income in five years. Also, conditions on the field as area, water availability, and initial investment are required. Using the Chilean costs and dollar-peso exchange rate, we can simulate several scenarios to understand the possible risks associated to this market. Also, this tool help to support decisions for government and individual farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixed%20integer%20problem" title="mixed integer problem">mixed integer problem</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20fruit%20production" title=" fresh fruit production"> fresh fruit production</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20decision%20model" title=" support decision model"> support decision model</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20and%20biosystems%20engineering" title=" agricultural and biosystems engineering"> agricultural and biosystems engineering</a> </p> <a href="https://publications.waset.org/abstracts/26591/optimization-model-for-support-decision-for-maximizing-production-of-mixed-fresh-fruit-farms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26591.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">438</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">101</span> Application of Sensory Thermography on Workers of a Wireless Industry in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Camargo%20Wilson">Claudia Camargo Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Javier%20de%20la%20Vega%20Bustillos"> Enrique Javier de la Vega Bustillos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Everardo%20Olgu%C3%ADn%20Tiznado"> Jesús Everardo Olguín Tiznado</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Andr%C3%A9s%20L%C3%B3pez%20Barreras"> Juan Andrés López Barreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20K.%20Enriquez"> Sandra K.

However, RoR schemes cost-effectiveness depends on the proper selection of site and design flow, which is a challenging task because it requires multivariate analysis. In this respect, this study presents the development of an investment decision support tool for assessing the optimal size of an RoR scheme considering the technical, environmental, and cost constraints. The net present value (NPV) from a project perspective is used as an objective function for supporting the investment decision. The tool has been tested by applying it to an actual RoR project recently proposed in Colombia. The obtained results show that the optimum point in financial terms does not match the flow that maximizes energy generation from exploiting the river's available flow. For the case study, the flow that maximizes energy corresponds to a value of 5.1 m3/s. In comparison, an amount of 2.1 m3/s maximizes the investors NPV. Finally, a sensitivity analysis is performed to determine the NPV as a function of the debt rate changes and the electricity prices and the CapEx. Even for the worst-case scenario, the optimal size represents a positive business case with an NPV of 2.2 USD million and an IRR 1.5 times higher than the discount rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20hydropower" title="small hydropower">small hydropower</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=RoR%20schemes" title=" RoR schemes"> RoR schemes</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20sizing" title=" optimal sizing"> optimal sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=objective%20function" title=" objective function"> objective function</a> </p> <a href="https://publications.waset.org/abstracts/136172/technical-environmental-and-financial-assessment-for-optimal-sizing-of-run-of-river-small-hydropower-project-case-study-in-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136172.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">132</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">99</span> Bioinformatic Screening of Metagenomic Fosmid Libraries for Identification of Biosynthetic Pathways Derived from the Colombian Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Fernanda%20Quiceno%20Vallejo">María Fernanda Quiceno Vallejo</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20del%20Portillo"> Patricia del Portillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Mercedes%20Zambrano"> María Mercedes Zambrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeisson%20Alejandro%20Triana"> Jeisson Alejandro Triana</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Calderon"> Dayana Calderon</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Anzola"> Juan Manuel Anzola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microorganisms from tropical ecosystems can be novel in terms of adaptations and conservation. Given the macrodiversity of Colombian ecosystems, it is possible that this diversity is also present in Colombian soils. Tropical soil bacteria could offer a potentially novel source of bioactive compounds. In this study we analyzed a metagenomic fosmid library constructed with tropical bacterial DNAs with the aim of understanding its underlying diversity and functional potential. 8640 clones from the fosmid library were sequenced by NANOPORE MiniOn technology, then analyzed with bioinformatic tools such as Prokka, AntiSMASH and Bagel4 in order to identify functional biosynthetic pathways in the sequences. The strains showed ample difference when it comes to biosynthetic pathways. In total we identified 4 pathways related to aryl polyene synthesis, 12 related to terpenes, 22 related to NRPs (Non ribosomal peptides), 11 related PKs (Polyketide synthases) and 7 related to RiPPs (bacteriocins). We designed primers for the metagenomic clones with the most BGCs (sample 6 and sample 2). Results show the biotechnological / pharmacological potential of tropical ecosystems. Overall, this work provides an overview of the genomic and functional potential of Colombian soil and sets the groundwork for additional exploration of tropical metagenomic sequencing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioactives" title="bioactives">bioactives</a>, <a href="https://publications.waset.org/abstracts/search?q=biosyntethic%20pathways" title=" biosyntethic pathways"> biosyntethic pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatic" title=" bioinformatic"> bioinformatic</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20gene%20clusters" title=" bacterial gene clusters"> bacterial gene clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20metabolites" title=" secondary metabolites"> secondary metabolites</a> </p> <a href="https://publications.waset.org/abstracts/144224/bioinformatic-screening-of-metagenomic-fosmid-libraries-for-identification-of-biosynthetic-pathways-derived-from-the-colombian-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144224.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">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">98</span> 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">97</span> Design and Construction of a Device to Facilitate the Stretching of a Plantiflexors Muscles in the Therapy of Rehabilitation for Patients with Spastic Hemiplegia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nathalia%20Andrea%20Calderon%20Lesmes">Nathalia Andrea Calderon Lesmes</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Barragan%20Parada"> Eduardo Barragan Parada</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Fernando%20Villegas%20Bermudez"> Diego Fernando Villegas Bermudez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spasticity in the plantiflexor muscles as a product of stroke (CVA-Cerebrovascular accident) restricts the mobility and independence of the affected people. Commonly, physiotherapists are in charge of manually performing the rehabilitation therapy known as Sustained Mechanical Stretching, rotating the affected foot of the patient in the sagittal plane. However, this causes a physical wear on the professional because it is a fatiguing movement. In this article, a mechanical device is developed to implement this rehabilitation therapy more efficiently. The device consists of a worm-crown mechanism that is driven by a crank to gradually rotate a platform in the sagittal plane of the affected foot, in order to achieve dorsiflexion. The device has a range of sagittal rotation up to 150° and has velcro located on the footplate that secures the foot. The design of this device was modeled by using CAD software and was checked structurally with a general purpose finite element software to be sure that the device is safe for human use. As a measurement system, a goniometer is used in the lateral part of the device and load cells are used to measure the force in order to determine the opposing torque exerted by the muscle. Load cells sensitivity is 1.8 ± 0.002 and has a repeatability of 0.03. Validation of the effectiveness of the device is measured by reducing the opposition torque and increasing mobility for a given patient. In this way, with a more efficient therapy, an improvement in the recovery of the patient's mobility and therefore in their quality of life can be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title="biomechanics">biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20device" title=" mechanical device"> mechanical device</a>, <a href="https://publications.waset.org/abstracts/search?q=plantiflexor%20muscles" title=" plantiflexor muscles"> plantiflexor muscles</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=spastic%20hemiplegia" title=" spastic hemiplegia"> spastic hemiplegia</a>, <a href="https://publications.waset.org/abstracts/search?q=sustained%20mechanical%20stretching" title=" sustained mechanical stretching"> sustained mechanical stretching</a> </p> <a href="https://publications.waset.org/abstracts/92967/design-and-construction-of-a-device-to-facilitate-the-stretching-of-a-plantiflexors-muscles-in-the-therapy-of-rehabilitation-for-patients-with-spastic-hemiplegia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92967.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">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> MindFlow: A Collective Intelligence-Based System for Helping Stress Pattern Diagnosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andres%20Frederic">Andres Frederic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present the MindFlow system supporting the detection and the diagnosis of stresses. The heart of the system is a knowledge synthesis engine allowing occupational health stakeholders (psychologists, occupational therapists and human resource managers) to formulate queries related to stress and responding to users requests by recommending a pattern of stress if one exists. The stress pattern diagnosis is based on expert knowledge stored in the MindFlow stress ontology including stress feature vector. The query processing may involve direct access to the MindFlow system by occupational health stakeholders, online communication between the MindFlow system and the MindFlow domain experts, or direct dialog between a occupational health stakeholder and a MindFlow domain expert. The MindFlow knowledge model is generic in the sense that it supports the needs of psychologists, occupational therapists and human resource managers. The system presented in this paper is currently under development as part of a Dutch-Japanese project and aims to assist organisation in the quick diagnosis of stress patterns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occupational%20stress" title="occupational stress">occupational stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20management" title=" stress management"> stress management</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20measurement" title=" physiological measurement"> physiological measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=accident%20prevention" title=" accident prevention"> accident prevention</a> </p> <a href="https://publications.waset.org/abstracts/23744/mindflow-a-collective-intelligence-based-system-for-helping-stress-pattern-diagnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23744.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">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">95</span> Water Treatment Using Eichhornia crassipes and Avifauna Control in The "La Mansión" Pond</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milda%20A.%20Cruz-Huaranga">Milda A.

Furthermore, tree trimming and cleaning activities were performed that reduced water pollution caused by organic deposits and feathers from wild birds. The impaired waterbody is located on the campus of the Peruvian Union University, 580 meters above sea level, with a volume of 6,405.336 m3, an area of 3,050.16 m2, 256.81 m perimeter, and 0.12 m3/s input flow. Seven 1.8 m2 floating systems were implemented, with 12 common water hyacinth plants in each system. Before implementing this system, a water quality analysis was performed to analyse the physical-chemical, microbiological, and organoleptic parameters. The pre-analysis revealed the pond’s critical condition, with electrical conductivity: 556 mg/l; phosphate: < 0.5; pH: 7.06; total solids: 412 mg/l; arsenic: <0.01; lead: 0.115; BOD5: 14; COD: 16.94; dissolved oxygen: 13; total coliforms: 24000 MCL/100 ml; and thermo-tolerant coliforms: 11000 MCL/100 ml. After implementing the system, the following results were obtained: EC: 495 mg/l; DO:9.2 mg/l; TS: 235 mg/l; BOD5: 7.7; COD: 8.47; Pb: 0.001 mg/l; TC: 460 MCL/100 ml; FC: 240 MCL/100 ml. Thus, we confirmed that the system is 78.79% efficient regarding the Peruvian ECA (Environmental Quality Standards) established for water according to DS #015-2015-MINAM. Therefore, the water is suitable for plant irrigation. Finally, we concluded that treating wastewater with the species Eichhornia Crassipes is efficient since an improvement was achieved in the impaired waterbody. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eichhornia%20crassipes" title="Eichhornia crassipes">Eichhornia crassipes</a>, <a href="https://publications.waset.org/abstracts/search?q=plantlets" title=" plantlets"> plantlets</a>, <a href="https://publications.waset.org/abstracts/search?q=cleaning" title=" cleaning"> cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=impaired%20waterbody" title=" impaired waterbody"> impaired waterbody</a>, <a href="https://publications.waset.org/abstracts/search?q=pond" title=" pond"> pond</a> </p> <a href="https://publications.waset.org/abstracts/156789/water-treatment-using-eichhornia-crassipes-and-avifauna-control-in-the-la-mansion-pond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156789.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">94</span> Reproductive Health Education (RHE) Toolkit for Science Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivy%20Jeralyn%20T.%20Andres">Ivy Jeralyn T.

Based on the findings, the teacher-respondents identified nine topics that can be included in the development of the RHE toolkit. The topics included are The Male Reproductive System, The Female Reproductive System, The Roles of Hormones in Male and Female Reproductive System, Menstrual Cycle, Fertilization, Pregnancy and Childbirth, Breastfeeding, Human Reproductive and Developmental Concerns and Reproductive Health Management and Diseases. The developed RHE Toolkit is remarked as very highly valid and very highly acceptable learning material. The validators and evaluators acknowledged the developed RHE toolkit as clear, creative, and academically useful supplemental material for educating reproductive health. Moreover, it follows the principles of SMART objectives, factual, timely, and relevant content for both learners and the community as a whole. Science teachers should employ the RHE Toolkit in teaching reproductive health education into their respective classes. It is also suggested that the developed RHE toolkit can be implemented to elementary pupils and the community, particularly in rural areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reproductive%20health%20education" title="reproductive health education">reproductive health education</a>, <a href="https://publications.waset.org/abstracts/search?q=toolkit" title=" toolkit"> toolkit</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20teachers" title=" science teachers"> science teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=supplemental%20material" title=" supplemental material"> supplemental material</a> </p> <a href="https://publications.waset.org/abstracts/174548/reproductive-health-education-rhe-toolkit-for-science-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174548.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">93</span> Identifying Metabolic Pathways Associated with Neuroprotection Mediated by Tibolone in Human Astrocytes under an Induced Inflammatory Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Osorio">Daniel Osorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Janneth%20Gonzalez"> Janneth Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Pinzon"> Andres Pinzon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, proteins and metabolic pathways associated with the neuroprotective response mediated by the synthetic neurosteroid tibolone under a palmitate-induced inflammatory model were identified by flux balance analysis (FBA). Three different metabolic scenarios (‘healthy’, ‘inflamed’ and ‘medicated’) were modeled over a gene expression data-driven constructed tissue-specific metabolic reconstruction of mature astrocytes. Astrocyte reconstruction was built, validated and constrained using three open source software packages (‘minval’, ‘g2f’ and ‘exp2flux’) released through the Comprehensive R Archive Network repositories during the development of this work. From our analysis, we predict that tibolone executes their neuroprotective effects through a reduction of neurotoxicity mediated by L-glutamate in astrocytes, inducing the activation several metabolic pathways with neuroprotective actions associated such as taurine metabolism, gluconeogenesis, calcium and the Peroxisome Proliferator Activated Receptor signaling pathways. Also, we found a tibolone associated increase in growth rate probably in concordance with previously reported side effects of steroid compounds in other human cell types. <p
