computers, which follows the ideas of the Ubiquitous Computing vision of Mark Weiser. In these, there is what is known as a Disappearing Computer Initiative, with users immersed in intelligent environments. Hence, technologies need to be adapted so that they are capable of replacing the traditional inputs to the system by embedding these in every-day artifacts. In this work, we present an approach, which uses Radiofrequency Identification (RFID) and Near Field Communication (NFC) technologies. In the latter, a new form of interaction appears by contact. We compare both technologies by analyzing their requirements and advantages. In addition, we propose using a combination of RFID and NFC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=touching%20interaction" title="touching interaction">touching interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=ambient%20intelligence" title=" ambient intelligence"> ambient intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=ubiquitous%20computing" title=" ubiquitous computing"> ubiquitous computing</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=NFC%20and%20RFID" title=" NFC and RFID"> NFC and RFID</a> </p> <a href="https://publications.waset.org/abstracts/40339/touching-interaction-an-nfc-rfid-combination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40339.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">505</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Forklift Allocation in Warehouse Operations with Restricted Halls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Becerra%20Fern%C3%A1ndez">Mauricio Becerra Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Rosana%20Romero%20Quiroga"> Olga Rosana Romero Quiroga</a>, <a href="https://publications.waset.org/abstracts/search?q=Elsa%20Cristina%20Gonz%C3%A1lez%20La%20Rotta"> Elsa Cristina González La Rotta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The logistics facilities design and construction is one of the strategic decisions that critically affects the performance of the company, from the economic perspective and relationship with customers. The case study company is the Colombian logistic sector leader, with over 60 years of experience, with sales of about one hundred twenty million dollars at the end of 2014. The preliminary design for the warehouse layout and operation includes a customer that provides approximately 17% of the profits of the company, considering the possibility of moving two forklifts in the warehouse halls. Some changes were not consider in previous stages of design, operations required forklift with different characteristics, whose size, do not allow the circulation of more than a forklift at a time. Therefore, it is necessary to assess the impact of this restriction on the warehouse operation, so decision makers implement actions to achieve efficient operation. The problem is addressed by recognizing logistics processes, which develop in a warehouse, collection of processes information behavior, the simulation of the current situation using ProModel software, model validation, making adjustments required, experiments design, conclusions and recommendations for the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design" title="design">design</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20events%20simulation" title=" discrete events simulation"> discrete events simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=forklift%20allocation" title=" forklift allocation"> forklift allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics%20facilities" title=" logistics facilities"> logistics facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=warehouse" title=" warehouse"> warehouse</a> </p> <a href="https://publications.waset.org/abstracts/41694/forklift-allocation-in-warehouse-operations-with-restricted-halls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41694.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">303</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">23</span> Modeling and Simulation of a Cycloconverter with a Bond Graph Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Ayala-Jaimes">Gerardo Ayala-Jaimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilberto%20Gonzalez-Avalos"> Gilberto Gonzalez-Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Allen%20A.%20Castillo"> Allen A.

In order to obtain significantly viable cellular concentration, a scale-up strategy for a liquid fermentation process (SmF) with two strains of <em>A. chroococcum </em>(named Ac1 and Ac10) was validated and adjusted at laboratory and pilot scale. A batch fermentation process under previously defined conditions was carried out on a biorreactor Infors®, model Minifors of 3.5 L, which served as a baseline for this research. For the purpose of increasing process efficiency, the effect of the reduction of stirring speed was evaluated in combination with a fed-batch-type fermentation laboratory scale. To reproduce the efficiency parameters obtained, a scale-up strategy with geometric and fluid dynamic behavior similarities was evaluated. According to the analysis of variance, this scale-up strategy did not have significant effect on cellular concentration and in laboratory and pilot fermentations (Tukey, p > 0.05). Regarding air consumption, fermentation process at pilot scale showed a reduction of 23% versus the baseline. The percentage of reduction related to energy consumption reduction under laboratory and pilot scale conditions was 96.9% compared with baseline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azotobacter%20chroococcum" title="Azotobacter chroococcum">Azotobacter chroococcum</a>, <a href="https://publications.waset.org/abstracts/search?q=scale-up" title=" scale-up"> scale-up</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20fermentation" title=" liquid fermentation"> liquid fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=fed-batch%20process" title=" fed-batch process"> fed-batch process</a> </p> <a href="https://publications.waset.org/abstracts/57291/adjustment-and-scale-up-strategy-of-pilot-liquid-fermentation-process-of-azotobacter-sp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57291.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">440</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">19</span> Cellular Automata Model for Car Accidents at a Signalized Intersection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Marzoug">Rachid Marzoug</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Lakouari"> Noureddine Lakouari</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Castillo%20T%C3%A9llez"> Beatriz Castillo Téllez</a>, <a href="https://publications.waset.org/abstracts/search?q=Margarita%20Castillo%20T%C3%A9llez"> Margarita Castillo Téllez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Alberto%20Mej%C3%ADa%20P%C3%A9rez"> Gerardo Alberto Mejía Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper developed a two-lane cellular automata model to explain the relationship between car accidents at a signalized intersection and traffic-related parameters. It is found that the increase of the lane-changing probability P?ₕ? increases the risk of accidents, besides, the inflow α and the probability of accidents Pₐ? exhibit a nonlinear relationship. Furthermore, depending on the inflow, Pₐ? exhibits three different phases. The transition from phase I to phase II is of first (second) order when P?ₕ?=0 (P?ₕ?>0). However, the system exhibits a second (first) order transition from phase II to phase III when P?ₕ?=0 (P?ₕ?>0). In addition, when the inflow is not very high, the green light length of one road should be increased to improve road safety. Finally, simulation results show that the traffic at the intersection is safer adopting symmetric lane-changing rules than asymmetric ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-lane%20intersection" title="two-lane intersection">two-lane intersection</a>, <a href="https://publications.waset.org/abstracts/search?q=accidents" title=" accidents"> accidents</a>, <a href="https://publications.waset.org/abstracts/search?q=fatality%20risk" title=" fatality risk"> fatality risk</a>, <a href="https://publications.waset.org/abstracts/search?q=lane-changing" title=" lane-changing"> lane-changing</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20transition" title=" phase transition"> phase transition</a> </p> <a href="https://publications.waset.org/abstracts/140637/cellular-automata-model-for-car-accidents-at-a-signalized-intersection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140637.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">218</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">18</span> Inventory Management to Minimize Storage Costs and Improve Delivery Time in a Pharmaceutical Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Israel%20Becerril%20Rosales">Israel Becerril Rosales</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Gonz%C3%A1lez%20De%20La%20Rosa"> Manuel González De La Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Villa%20S%C3%A1nchez"> Gerardo Villa Sánchez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the effects that produce not having a good inventory management is analyzed, in addition of the way that how it affects the storage costs.

The results were not optimal, since in all its raw materials (RM) have overstocking, the warehouse capacity is only used by 61%, does not have a specific place for each of its RM, causing that the delivery times increases and makes difficult a cyclical inventory. These shortcomings allowed to view and select as design alternatives the inventory ABC, so that depending on the consumption of each RM would be redistributed by using economic amount requested. Also, the Delphi method to ensure the practical applicability of the proposed tool was used, taking in account comments and suggestions of the involved experts, as well as the compliance of NOM-059-SSA1-2015 good manufacturing practices of drug.

The first (classical), is widely used in Surveying Schools and it is based on the use of explicit formulas obtained from Taylor expansions of sine and cosine functions. The second one (alternative) is a very simple algorithm, based on the numerical solution of the initial value problems giving the clothoid parameterization. Both methods are compared in some typical surveying problems. The alternative method does not use complex formulas and so it is conceptually very simple and easy to apply. It gives good results, even if the classical method goes wrong (if the quotient between length and radius of curvature is high), needs no subsequent translations nor rotations and, consequently, it seems an efficient tool for designing the layout of roads and railway tracks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transition%20curves" title="transition curves">transition curves</a>, <a href="https://publications.waset.org/abstracts/search?q=railroad%20and%20highway%20engineering" title=" railroad and highway engineering"> railroad and highway engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=Runge-Kutta%20methods" title=" Runge-Kutta methods"> Runge-Kutta methods</a> </p> <a href="https://publications.waset.org/abstracts/33251/an-alternative-method-for-computing-clothoids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33251.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">283</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">16</span> Proposed Solutions Based on Affective Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Adrian%20Cardenas%20Jorge">Diego Adrian Cardenas Jorge</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Mirando%20Guisado"> Gerardo Mirando Guisado</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Barrientos%20Padilla"> Alfredo Barrientos Padilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A system based on Affective Computing can detect and interpret human information like voice, facial expressions and body movement to detect emotions and execute a corresponding response. This data is important due to the fact that a person can communicate more effectively with emotions than can be possible with words. This information can be processed through technological components like Facial Recognition, Gait Recognition or Gesture Recognition. As of now, solutions proposed using this technology only consider one component at a given moment. This research investigation proposes two solutions based on Affective Computing taking into account more than one component for emotion detection. The proposals reflect the levels of dependency between hardware devices and software, as well as the interaction process between the system and the user which implies the development of scenarios where both proposals will be put to the test in a live environment. Both solutions are to be developed in code by software engineers to prove the feasibility. To validate the impact on society and business interest, interviews with stakeholders are conducted with an investment mind set where each solution is labeled on a scale of 1 through 5, being one a minimum possible investment and 5 the maximum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affective%20computing" title="affective computing">affective computing</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion%20detection" title=" emotion detection"> emotion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20recognition" title=" face recognition"> face recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=gait%20recognition" title=" gait recognition"> gait recognition</a> </p> <a href="https://publications.waset.org/abstracts/43577/proposed-solutions-based-on-affective-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43577.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">369</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">15</span> Flipped Learning Application on the Development of Capabilities for Civil Engineering Education in Labs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hector%20Barrios-Pi%C3%B1a">Hector Barrios-Piña</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia%20Garc%C3%ADa-Arellano"> Georgia García-Arellano</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvador%20Garc%C3%ADa-Rodr%C3%ADguez"> Salvador García-Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Bocanegra-Garc%C3%ADa"> Gerardo Bocanegra-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashi%20Kant"> Shashi Kant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work shows the methodology of application and the effectiveness of the <em>Flipped Learning</em> technique for Civil Engineering laboratory classes. It was experimented by some of the professors of the Department of Civil Engineering at Tecnológico de Monterrey while teaching their laboratory classes. A total of 28 videos were created. The videos primarily demonstrate instructions of the experimental practices other than the usage of tools and materials. The technique allowed the students to prepare for their classes in advance. A survey was conducted on the participating professors and students (semester of August-December 2019) to quantify the effectiveness of the <em>Flipped Learning</em> technique. The students reported it as an excellent way of improving their learning aptitude, including self-learning whereas, the professors felt it as an efficient technique for optimizing their class session, which also provided an extra slot for class-interaction. A comparison of grades was analyzed between the students of the traditional classes and with <em>Flipped Learning</em>. It did not distinguish the benefits of <em>Flipped Learning</em>. However, the positive responses from the students and the professors provide an impetus for continuing and promoting the <em>Flipped Learning</em> technique in future classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flipped%20learning" title="flipped learning">flipped learning</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20classes" title=" laboratory classes"> laboratory classes</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20engineering" title=" civil engineering"> civil engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=competences%20development" title=" competences development"> competences development</a> </p> <a href="https://publications.waset.org/abstracts/124027/flipped-learning-application-on-the-development-of-capabilities-for-civil-engineering-education-in-labs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124027.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">161</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">14</span> Surgical Planning for the Removal of Cranial Spheno-orbital Meningioma by Using Personalized Polymeric Prototypes Obtained with Additive Manufacturing Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Freddy%20Patricio%20Moncayo-Matute">Freddy Patricio Moncayo-Matute</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Gerardo%20Pe%C3%B1a-Tapia"> Pablo Gerardo Peña-Tapia</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%A1zquez-Silva%20Efr%C3%A9n"> Vázquez-Silva Efrén</a>, <a href="https://publications.waset.org/abstracts/search?q=Pa%C3%BAl%20Bol%C3%ADvar%20Torres-Jara"> Paúl Bolívar Torres-Jara</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20Patricia%20Moya-Loaiza"> Diana Patricia Moya-Loaiza</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Abad-Farf%C3%A1n"> Gabriela Abad-Farfán</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study describes a clinical case and the results on the application of additive manufacturing for the surgical planning in the removal of a cranial spheno-orbital meningioma.

Therefore, a biopesticide prototype based on B. bassiana strain Bv060 was developed at Corpoica laboratories. For the production of B. bassiana conidia, a baseline fermentation was performed at laboratory in a solid medium using broken rice as a substrate, a temperature of 25±2 °C and a relative humidity of 60±10%. The experimental design was completely randomized, with a three-time repetition. These culture conditions resulted in an average conidial concentration of 1.48x10^10 conidia/g, a yield of 13.07 g/kg dry substrate and a productivity of 8.83x10^7 conidia/g*h were achieved. Consequently, the objective of this study was to evaluate the influence of the particle size reduction of rice (<1 mm) and the addition of a complex nitrogen source over conidia production and efficiency parameters in a solid-state fermentation, in a completely randomized experiment with a three-time repetition. For this aim, baseline fermentation conditions of temperature and humidity were employed in a semisolid culture medium with powdered rice (10%) and a complex nitrogen source (8%). As a result, it was possible to increase conidial concentration until 9.87x10^10 conidia/g, yield to 87.07 g/g dry substrate and productivity to 3.43x10^8 conidia/g*h. This suggested that conidial concentration and yield in semisolid fermentation increased almost 7 times compared with baseline while the productivity increased 4 times. Finally, the designed system for semisolid-state fermentation allowed to achieve an easy conidia recovery, which means reduction in time and costs of the production process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beauveria%20bassiana" title="Beauveria bassiana">Beauveria bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20fermentation" title=" solid state fermentation"> solid state fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=semisolid%20medium%20culture" title=" semisolid medium culture"> semisolid medium culture</a> </p> <a href="https://publications.waset.org/abstracts/57293/biomass-production-improvement-of-beauveria-bassiana-at-laboratory-scale-for-a-biopesticide-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57293.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">301</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">12</span> Non-Dominated Sorting Genetic Algorithm (NSGA-II) for the Redistricting Problem in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonin%20Ponsich">Antonin Ponsich</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Alfredo%20Rincon%20Garcia"> Eric Alfredo Rincon Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Anselmo%20Mora%20Gutierrez"> Roman Anselmo Mora Gutierrez</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Angel%20Gutierrez%20Andrade"> Miguel Angel Gutierrez Andrade</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Gerardo%20De%20Los%20Cobos%20Silva"> Sergio Gerardo De Los Cobos Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Lara%20Velzquez"> Pedro Lara Velzquez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electoral zone design problem consists in redrawing the boundaries of legislative districts for electoral purposes in such a way that federal or state requirements are fulfilled. In Mexico, this process has been historically carried out by the National Electoral Institute (INE), by optimizing an integer nonlinear programming model, in which population equality and compactness of the designed districts are considered as two conflicting objective functions, while contiguity is included as a hard constraint. The solution technique used by the INE is a Simulated Annealing (SA) based algorithm, which handles the multi-objective nature of the problem through an aggregation function. The present work represents the first intent to apply a classical Multi-Objective Evolutionary Algorithm (MOEA), the second version of the Non-dominated Sorting Genetic Algorithm (NSGA-II), to this hard combinatorial problem. First results show that, when compared with the SA algorithm, the NSGA-II obtains promising results. The MOEA manages to produce well-distributed solutions over a wide-spread front, even though some convergence troubles for some instances constitute an issue, which should be corrected in future adaptations of MOEAs to the redistricting problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20optimization" title="multi-objective optimization">multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=NSGA-II" title=" NSGA-II"> NSGA-II</a>, <a href="https://publications.waset.org/abstracts/search?q=redistricting" title=" redistricting"> redistricting</a>, <a href="https://publications.waset.org/abstracts/search?q=zone%20design%20problem" title=" zone design problem"> zone design problem</a> </p> <a href="https://publications.waset.org/abstracts/69281/non-dominated-sorting-genetic-algorithm-nsga-ii-for-the-redistricting-problem-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69281.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">367</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">11</span> Heritage Preservation and Cultural Tourism; The 'Pueblos Mágicos' Program and Its Role in Preserving Traditional Architecture in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Rodr%C3%ADguez%20Espinosa">Claudia Rodríguez Espinosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Elizabeth%20P%C3%A9rez%20M%C3%BAzquiz"> Erika Elizabeth Pérez Múzquiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Pueblos Mágicos federal program tries to preserve the traditional environment of small towns (under 20,000 inhabitants), through economic investments, legislation, and legal aid. To access the program, it’s important to cover 8 requirements; one of them is the fourth, which considers ‘Promotion of symbolic and differentiated touristic attractions, such as architecture, emblematic buildings, festivities and traditions, artisan production, traditional cuisine, and touristic services that guarantee their commercialization along with assistantship and security services’. With this objective in mind, the Federal government of Mexico had developed local programs to protect emblematic public buildings in each of the 83 towns included in the Pueblos Mágicos program that involved federal and local administrations as well as local civil associations, like Adopte una Obra de Arte. In this paper, we present 3 different intervention cases: first the restoration project (now concluded) of the 16th century monastery of Santa María Magdalena in Cuitzeo, an enormous building which took 6 years to be completely restored. Second case, the public spaces intervention in Pátzcuaro, included the Plaza Grande or Vasco de Quiroga square, and the access to the arts and crafts house known as Casa de los once patios or eleven backyards house. The third case is the recovery project of the 16th century atrium of the Tzintzuntzan monastery that included the original olive trees brought by Franciscans monks to this town in the middle 1500’s. This paper tries to present successful preservation projects in 3 different scales: building, urban spaces and landscape; and in 3 different towns with the objective to preserve public architecture, public spaces and cultural traditions.

Three different samples were prepared: A, B and C, which presented differences in relation to the recipe, pasteurization technique and packaging on which the trend of the shelf-life indicator parameters was evaluated during a period of prolonged shelf life. The analytical plan involved the measurement of microbiological, chemical-physical and organoleptic parameters over 7 moments of storage selected in a period of 33 days. CBT, LAB, enterobacteria, E. coli, yeasts, molds, S. coagulase positive, B. cereus, Salmonella spp and L. monocytogenes, pH, Aw, Kreiss test, peroxides, atmosphere inside the packages, and organoleptic characteristics were determined. The results demonstrated the effect of post-packaging pasteurization on the shelf life of fresh from frozen products. However, the products pasteurized at 95°C in the absence of steam showed microbiological parameters that were not appropriate for an extended shelf life of up to 60 days. On the contrary, the samples pasteurized at 98°C with steam saturation and counterpressure showed values compatible with an extended shelf life. The results of the chemical-physical analyses highlighted how recipe and packaging affect the chemical-physical and organoleptic parameters. In conclusion, this preliminary study confirmed the effectiveness of post-packaging pasteurization treatments aimed at extending the shelf life of the product, helping the food company to occupy market niches even very distant from the production sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title="shelf life">shelf life</a>, <a href="https://publications.waset.org/abstracts/search?q=REPFED%E2%80%99s%20product" title=" REPFED’s product"> REPFED’s product</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20durability" title=" extended durability"> extended durability</a>, <a href="https://publications.waset.org/abstracts/search?q=pasteurization" title=" pasteurization"> pasteurization</a> </p> <a href="https://publications.waset.org/abstracts/188933/shelf-life-of-frozen-processed-foods-for-extended-durability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188933.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">28</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">9</span> Molecular Identification and Evolutionary Status of Lucilia bufonivora: An Obligate Parasite of Amphibians in Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Arias">Gerardo Arias</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Wall"> Richard Wall</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamie%20Stevens"> Jamie Stevens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lucilia bufonivora Moniez, is an obligate parasite of toads and frogs widely distributed in Europe. Its sister taxon Lucilia silvarum Meigen behaves mainly as a carrion breeder in Europe, however it has been reported as a facultative parasite of amphibians. These two closely related species are morphologically almost identical, which has led to misidentification, and in fact, it has been suggested that the amphibian myiasis cases by L. silvarum reported in Europe should be attributed to L. bufonivora. Both species remain poorly studied and their taxonomic relationships are still unclear. The identification of the larval specimens involved in amphibian myiasis with molecular tools and phylogenetic analysis of these two closely related species may resolve this problem. In this work seventeen unidentified larval specimens extracted from toad myiasis cases of the UK, the Netherlands and Switzerland were obtained, their COX1 (mtDNA) and EF1-α (Nuclear DNA) gene regions were amplified and then sequenced. The 17 larval samples were identified with both molecular markers as L. bufonivora. Phylogenetic analysis was carried out with 10 other blowfly species, including L. silvarum samples from the UK and USA. Bayesian Inference trees of COX1 and a combined-gene dataset suggested that L. silvarum and L. bufonivora are separate sister species. However, the nuclear gene EF1-α does not appear to resolve their relationships, suggesting that the rates of evolution of the mtDNA are much faster than those of the nuclear DNA. This work provides the molecular evidence for successful identification of L. bufonivora and a molecular analysis of the populations of this obligate parasite from different locations across Europe. The relationships with L. silvarum are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calliphoridae" title="calliphoridae">calliphoridae</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20evolution" title=" molecular evolution"> molecular evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=myiasis" title=" myiasis"> myiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=obligate%20parasitism" title=" obligate parasitism"> obligate parasitism</a> </p> <a href="https://publications.waset.org/abstracts/77861/molecular-identification-and-evolutionary-status-of-lucilia-bufonivora-an-obligate-parasite-of-amphibians-in-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77861.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">8</span> Cognitive Effects of Repetitive Transcranial Magnetic Stimulation in Patients with Parkinson's Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Munguia">Ana Munguia</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Ortiz"> Gerardo Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Guadalupe%20Gonzalez"> Guadalupe Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiacro%20Jimenez"> Fiacro Jimenez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parkinson's disease (PD) is a neurodegenerative disorder that causes motor and cognitive symptoms. The first-choice treatment for these patients is pharmacological, but this generates several side effects. Because of that new treatments were introduced such as Repetitive Transcranial Magnetic Stimulation (rTMS) in order to improve the life quality of the patients. Several studies suggest significant changes in motor symptoms. However, there is a great diversity in the number of pulses, amplitude, frequency and stimulation targets, which results in inconsistent data. In addition, these studies do not have an analysis of the neuropsychological effects of the treatment. The main purpose of this study is to evaluate the impact of rTMS on the cognitive performance of 6 patients with H&Y III and IV (45-65 years, 3 men and 3 women). An initial neuropsychological and neurological evaluation was performed. Patients were randomized into two groups; in the first phase one received rTMS in the supplementary motor area, the other group in the dorsolateral prefrontal cortex contralateral to the most affected hemibody. In the second phase, each group received the stimulation in the area that he had not been stimulated previously. Reassessments were carried out at the beginning, at the end of each phase and a follow-up was carried out 6 months after the conclusion of the stimulation. In these preliminary results, it is reported that there's no statistically significant difference before and after receiving rTMS in the neuropsychological test scores of the patients, which suggests that the cognitive performance of patients is not detrimental. There are even tendencies towards an improvement in executive functioning after the treatment. What added to motor improvement, showed positive effects in the activities of the patients' daily life. In a later and more detailed analysis, will be evaluated the effects in each of the patients separately in relation to the functionality of the patients in their daily lives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parkinson%27s%20disease" title="Parkinson's disease">Parkinson's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=rTMS" title=" rTMS"> rTMS</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive" title=" cognitive"> cognitive</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/84791/cognitive-effects-of-repetitive-transcranial-magnetic-stimulation-in-patients-with-parkinsons-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84791.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">145</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">7</span> Viscoelastic Properties of Sn-15%Pb Measured in an Oscillation Test </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Sanjuan%20Sanjuan">Gerardo Sanjuan Sanjuan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngel%20Enrique%20Chav%C3%A9z%20Castellanos"> Ángel Enrique Chavéz Castellanos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The knowledge of the rheological behavior of partially solidified metal alloy is an important issue when modeling and simulation of die filling in semisolid processes. Many experiments for like steady state, the step change in shear rate tests, shear stress ramps have been carried out leading that semi-solid alloys exhibit shear thinning, thixotropic behavior and yield stress. More advanced investigation gives evidence some viscoelastic features can be observed. The viscoelastic properties of materials are determinate by transient or dynamic methods; unfortunately, sparse information exists about oscillation experiments. The aim of this present work is to use small amplitude oscillatory tests for knowledge properties such as G´ and G´´. These properties allow providing information about materials structure. For this purpose, we investigated tin-lead alloy (Sn-15%Pb) which exhibits a similar microstructure to aluminum alloys and is the classic alloy for semisolid thixotropic studies. The experiments were performed with parallel plates rheometer AR-G2. Initially, the liquid alloy is cooled down to the semisolid range, a specific temperature to guarantee a constant fraction solid. Oscillation was performed within the linear viscoelastic regime with a strain sweep. So, the loss modulus G´´, the storage modulus G´ and the loss angle (δ) was monitored. In addition a frequency sweep at a strain below the critical strain for characterized its structure. This provides more information about the interactions among solid particles on a liquid matrix. After testing, the sample was removed then cooled, sectioned and examined metallographically. These experiments demonstrate that the viscoelasticity is sensitive to the solid fraction, and is strongly influenced by the shape and size of particles solid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheology" title="rheology">rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=semisolid%20alloys" title=" semisolid alloys"> semisolid alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=thixotropic" title=" thixotropic"> thixotropic</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a> </p> <a href="https://publications.waset.org/abstracts/32253/viscoelastic-properties-of-sn-15pb-measured-in-an-oscillation-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32253.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">376</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">6</span> Phenology and Size in the Social Sweat Bee, Halictus ligatus, in an Urban Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachel%20A.%20Brant">Rachel A.

Camilo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The social sweat bee, Halictus ligatus, has been documented to alter its phenology as a response to changes in temporal dynamics of resources. Furthermore, H. ligatus exhibits polyethism in natural environments as a consequence of the variation in resources. Yet, we do not know if or how H. ligatus responds to these variations in urban environments. As urban environments become much more widespread, and human population is expected to reach nine billion by 2050, it is crucial to distinguish how resources are allocated by bees in cities. We hypothesize that in urban regions, where floral availability varies with human activity, H. ligatus will exhibit polyethism in order to match the extremely localized spatial variability of resources. We predict that in an urban setting, where resources vary both spatially and temporally, the phenology of H. ligatus will alter in response to these fluctuations. This study was conducted in Saint Louis, Missouri, at fifteen sites each varying in size and management type (community garden, urban farm, prairie restoration). Bees were collected by hand netting from 2013-2016. Results suggest that the largest individuals, mostly gynes, occurred in lower income neighborhood community gardens in May and August. We used a model averaging procedure, based on information theoretical methods, to determine a best model for predicting bee size. Our results suggest that month and locality within the city are the best predictors of bee size. Halictus ligatus was observed to comply with the predictions of polyethism from 2013 to 2015. However, in 2016 there was an almost complete absence of the smallest worker castes. This is a significant deviation from what is expected under polyethism. This could be attributed to shifts in planting decisions, shifts in plant-pollinator matches, or local climatic conditions. Further research is needed to determine if this divergence from polyethism is a new strategy for the social sweat bee as climate continues to alter or a response to human dominated landscapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyethism" title="polyethism">polyethism</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20environment" title=" urban environment"> urban environment</a>, <a href="https://publications.waset.org/abstracts/search?q=phenology" title=" phenology"> phenology</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sweat%20bee" title=" social sweat bee"> social sweat bee</a> </p> <a href="https://publications.waset.org/abstracts/74595/phenology-and-size-in-the-social-sweat-bee-halictus-ligatus-in-an-urban-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74595.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">221</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">5</span> Local Farmer’s Perception on the Role of Room for the River in Livelihoods: Case Study in An Phu District, An Giang Province, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Vo%20Thi%20Minh">Hoang Vo Thi Minh</a>, <a href="https://publications.waset.org/abstracts/search?q=Duyen%20Nguyen%20Thi%20Phuong"> Duyen Nguyen Thi Phuong</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Van%20Halsema"> Gerardo Van Halsema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As one of the deltas which is extremely vulnerable to climate change, the Mekong Delta, Vietnam is facing many challenges that need to be addressed in strategic and holistic ways. In this study scope, a strategic delta planning is recently considered as a new vision of Adaptive Delta Management for the Mekong Delta. In Adaptive Delta Management, Room for the Rivers (RftR) has been formulated as a typical innovation, which is currently in need of careful consideration for implementing in the Mekong Delta’s planning process. This study then attempts to investigate the roles and analyze sociological aspects of the RftR as potential strategic 'soft' measure, in upstream of Hau River in An Phu district, An Giang province, especially in terms of its so-called multifunctions. The study applied social science approach embedded with a few qualitative methods including in-depth interviews and questionnaire distribution and conjoint analysis as a quantitative approach. The former mainly aims at gaining the local community’s perceptions about the RftR solution. The latter tries to gain farmers’ willingness to accept (WTA) with regard to their level of preference towards the three selected solutions which are considered as strategic plans for sustainably developing the MD. Qualitative data analysis shows that, farmers perceive RftR as very useful for their livelihoods due to its multifunctions as well as in terms of water management. The quantitative results illustrated that respondents expressed their WTAs on RftR as 84. 240 thousand VND / year. Amongst the three solutions that are analysed within this study (Floating rice for upper delta, Room for the Rivers for the Middle, and Shrimp-Mangrove integration for the coastal delta), RfrR was ranked as second preference from respondents. This result is not exactly reflecting the real values of these three mentioned solutions but showing a tendency that can be seen as a reference for the decision-makers in delta planning processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strategic%20delta%20planning" title="strategic delta planning">strategic delta planning</a>, <a href="https://publications.waset.org/abstracts/search?q=room%20for%20the%20River" title=" room for the River"> room for the River</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers%E2%80%99%20perception" title=" farmers’ perception"> farmers’ perception</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness-to-accept" title=" willingness-to-accept"> willingness-to-accept</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20livelihoods" title=" local livelihoods"> local livelihoods</a> </p> <a href="https://publications.waset.org/abstracts/75759/local-farmers-perception-on-the-role-of-room-for-the-river-in-livelihoods-case-study-in-an-phu-district-an-giang-province-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75759.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">228</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">4</span> Effect of Phytohormones on the Development and Nutraceutical Characteristics of the Fruit Capsicum annuum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rossy%20G.%20Olan%20Villegas">Rossy G.

The fruit (pepper) contains bioactive components such as carotenoids, phenolic compounds and capsaicinoids that improve health. However, pepper cultivation is affected by biotic and abiotic factors that decrease yield. Some phytohormones like gibberellins and auxins induce the formation and development of fruit in several plants. In this study, we evaluated the effect of the exogenous application of phytohormones like gibberellic acid and indolbutyric acid on fruit development of jalapeno pepper plants, the protein profile of plant tissues, the accumulation of bioactive compounds and antioxidant activity in the pericarp and seeds. For that, plants were sprinkled with these phytohormones. The fruit collection for the control, indolbutyric acid and gibberellic acid treatments was 7 peppers per plant; however, for the treatment that combines indolbutyric acid and gibberellic acid, a fruit with the shortest length (1.52 ± 1.00 cm) and weight (0.41 ± 1.0 g) was collected compared to fruits of plants grown under other treatments. The length (4,179 ± 0,130 cm) and weight of the fruit (8,949 ± 0.583 g) increased in plants treated with indolbutyric acid, but these characteristics decreased with the application of GA3 (length of 3,349 ± 0.127 cm and a weight 4,429 ± 0.144 g). The content of carotenes and phenolic compounds increased in plants treated with GA3 (1,733 ± 0.092 and 1,449 ± 0.009 mg / g, respectively) or indolbutyric acid (1,164 ± 0.042 and 0.970 ± 0.003 mg / g). However, this effect was not observed in plants treated with both phytohormones (0.238 ± 0.021 and 0.218 ± 0.004 mg / g). Capsaicin content was higher in all treatments; but it was more noticeable in plants treated with both phytohormones, the value being 0.913 ± 0.001 mg / g (three times greater in amount). The antioxidant activity was measured by 3 different assays, 2,2-diphenyl-1-picrylhydrazyl (DPPH), antioxidant power of ferric reduction (FRAP) and 2,2'-Azinobis-3-ethyl-benzothiazoline-6-sulfonic acid ( ABTS) to find the minimum inhibitory concentration of the reducing radical (IC50 and EC50). Significant differences were observed from the application of the phytohormone, being the fruits treated with gibberellins, which had a greater accumulation of bioactive compounds. Our results suggest that the application of phytohormones modifies the development of fruit and its content of bioactive compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxins" title="auxins">auxins</a>, <a href="https://publications.waset.org/abstracts/search?q=capsaicinoids" title=" capsaicinoids"> capsaicinoids</a>, <a href="https://publications.waset.org/abstracts/search?q=carotenoids" title=" carotenoids"> carotenoids</a>, <a href="https://publications.waset.org/abstracts/search?q=gibberellins" title=" gibberellins"> gibberellins</a> </p> <a href="https://publications.waset.org/abstracts/122815/effect-of-phytohormones-on-the-development-and-nutraceutical-characteristics-of-the-fruit-capsicum-annuum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122815.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">114</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">3</span> Mortar Positioning Effects on Uniaxial Compression Behavior in Hollow Concrete Block Masonry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20%C3%81lvarez%20P%C3%A9rez">José Álvarez Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%C3%B3n%20Garc%C3%ADa%20Cede%C3%B1o"> Ramón García Cedeño</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Fajardo-San%20Miguel"> Gerardo Fajardo-San Miguel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20H.%20Ch%C3%A1vez%20G%C3%B3mez"> Jorge H.

These properties are obtained through experimental tests conducted on prisms or wallettes and depend on various factors, with the HCB contributing significantly to overall strength. One influential factor in the compressive behaviour of masonry is the thickness and method of mortar placement. Mexican regulations stipulate mortar placement over the entire net area (full-shell) for strength computation based on the gross area. However, in professional practice, there's a growing trend to place mortar solely on the lateral faces. Conversely, the United States of America standard dictates mortar placement and computation over the net area of HCB. The Canadian standard specifies mortar placement solely on the lateral face (Face-Shell-Bedding), where computation necessitates the use of the effective load area, corresponding to the mortar's placement area. This research aims to evaluate the influence of different mortar placement methods on the axial compression behaviour of HCBM. To achieve this, an experimental campaign was conducted, including: (1) 10 HCB specimens with mortar on the entire net area, (2) 10 HCB specimens with mortar placed on the lateral faces, (3) 10 prisms of 2-course HCB under axial compression with mortar in full-shell, (4) 10 prisms of 2-course HCB under axial compression with mortar in face-shell-bedding, (5) 10 prisms of 3-course HCB under axial compression with mortar in full-shell, (6) 10 prisms of 3-course HCB under axial compression with mortar in face-shell-bedding, (7) 10 prisms of 4-course HCB under axial compression with mortar in full-shell, and, (8) 10 prisms of 4-course HCB under axial compression with mortar in face-shell-bedding. A combination of sulphur and fly ash in a 2:1 ratio was used for the capping material, meeting the average compressive strength requirement of over 35 MPa as per NMX-C-036 standards. Additionally, a mortar with a strength of over 17 MPa was utilized for the prisms. The results indicate that prisms with mortar placed over the full-shell exhibit higher strength compared to those with mortar over the face-shell-bedding. However, the elastic modulus was lower for prisms with mortar placement over the full-shell compared to face-shell bedding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry" title="masonry">masonry</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20concrete%20blocks" title=" hollow concrete blocks"> hollow concrete blocks</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar%20placement" title=" mortar placement"> mortar placement</a>, <a href="https://publications.waset.org/abstracts/search?q=prisms%20tests" title=" prisms tests"> prisms tests</a> </p> <a href="https://publications.waset.org/abstracts/179332/mortar-positioning-effects-on-uniaxial-compression-behavior-in-hollow-concrete-block-masonry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179332.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">61</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">2</span> Application of Acoustic Emissions Related to Drought Can Elicit Antioxidant Responses and Capsaicinoids Content in Chili Pepper Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Helena%20%20Caicedo%20Lopez">Laura Helena Caicedo Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Miguel%20Contreras%20Medina"> Luis Miguel Contreras Medina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Gerardo%20Guevara%20Gonzales"> Ramon Gerardo Guevara Gonzales</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20E.%20%20Andrade"> Juan E.

Five main peaks were detected using a 2 Hz resolution vibrometer laser (Polytec-B&K). These peaks or “characteristic frequencies” were used as acoustic emissions (AEs) treatment, transforming these signals into audible sound with the frequency (Hz) content of each hydric stress. Capsaicinoids (CAPs) are the main, secondary metabolites of chili pepper plants and are known to increase during hydric stress conditions or short drought-periods. The AEs treatments were applied in two plant stages: the first one was in the pre-anthesis stage to evaluate the genes that encode the transcription of enzymes responsible for diverse metabolic activities of C. annuum plants. For example, the antioxidant responses such as peroxidase (POD), superoxide dismutase (Mn-SOD). Also, phenyl-alanine ammonia-lyase (PAL) involved in the biosynthesis of the phenylpropanoid compounds. The chalcone synthase (CHS) related to the natural defense mechanisms and species-specific aquaporin (CAPIP-1) that regulate the flow of water into and out of cells. The second stage was at 40 days after flowering (DAF) to evaluate the biochemical effect of AEs related to hydric stress on capsaicinoids production. These two experiments were conducted to identify the molecular responses of C. annuum plants to AE. Moreover, to define AEs could elicit any increase in the capsaicinoids content after a one-week exposition to AEs treatments. The results show that all AEs treatment signals (LHS, MHS, and HHS) were significantly different compared to the non-acoustic emission control (NAE). Also, the AEs induced the up-regulation of POD (~2.8, 2.9, and 3.6, respectively). The gene expression of another antioxidant response was particularly treatment-dependent. The HHS induced and overexpression of Mn-SOD (~0.23) and PAL (~0.33). As well, the MHS only induced an up-regulation of the CHs gene (~0.63). On the other hand, CAPIP-1 gene gas down-regulated by all AEs treatments LHS, MHS, and HHS ~ (-2.4, -0.43 and -6.4, respectively). Likewise, the down-regulation showed particularities depending on the treatment. LHS and MHS induced downregulation of the SOD gene ~ (-1.26 and -1.20 respectively) and PAL (-4.36 and 2.05, respectively). Correspondingly, the LHS and HHS showed the same tendency in the CHs gene, respectively ~ (-1.12 and -1.02, respectively). Regarding the elicitation effect of AE on the capsaicinoids content, additional treatment controls were included. A white noise treatment (WN) to prove the frequency-selectiveness of signals and a hydric stressed group (HS) to compare the CAPs content. Our findings suggest that WN and NAE did not present differences statically. Conversely, HS and all AEs treatments induced a significant increase of capsaicin (Cap) and dihydrocapsaicin (Dcap) after one-week of a treatment. Specifically, the HS plants showed an increase of 8.33 times compared to the NAE and WN treatments and 1.4 times higher than the MHS, which was the AEs treatment with a larger induction of Capsaicinoids among treatments (5.88) and compared to the controls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission" title="acoustic emission">acoustic emission</a>, <a href="https://publications.waset.org/abstracts/search?q=capsaicinoids" title=" capsaicinoids"> capsaicinoids</a>, <a href="https://publications.waset.org/abstracts/search?q=elicitors" title=" elicitors"> elicitors</a>, <a href="https://publications.waset.org/abstracts/search?q=hydric%20stress" title=" hydric stress"> hydric stress</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20signaling" title=" plant signaling"> plant signaling</a> </p> <a href="https://publications.waset.org/abstracts/126690/application-of-acoustic-emissions-related-to-drought-can-elicit-antioxidant-responses-and-capsaicinoids-content-in-chili-pepper-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126690.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">171</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">1</span> Valorization of Underutilized Fish Species Through a Multidisciplinary Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tiziana%20Pepe">Tiziana Pepe</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Manfreda"> Gerardo Manfreda</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Ianieri"> Adriana Ianieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Aniello%20Anastasio"> Aniello Anastasio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sustainable exploitation of marine biological resources is among the most important objectives of the EU's Common Fisheries Policy (CFP). Currently, Europe imports about 65% of its fish products, indicating that domestic production does not meet consumer demand. Despite the availability of numerous commercially significant fish species, European consumption is concentrated on a limited number of products (e.g., sea bass, sea bream, shrimp). Many native species, present in large quantities in the Mediterranean Sea, are little known to consumers and are therefore considered ‘fishing by-products’. All the data presented so far indicate a significant waste of local resources and the overexploitation of a few fish stocks. It is therefore necessary to develop strategies that guide the market towards sustainable conversion. The objective of this work was to valorize underutilized fish species of the Mediterranean Sea through a multidisciplinary approach. To this end, three fish species were sampled: Atlantic Horse Mackerel (Trachurus trachurus), Bogue (Boops boops), and Common Dolphinfish (Coryphaena hippurus). Nutritional properties (water %, fats, proteins, ashes, salts), physical/chemical properties (TVB-N, histamine, pH), and rheological properties (color, texture, viscosity) were analyzed. The analyses were conducted on both fillets and processing by-products. Additionally, mitochondrial DNA (mtDNA) was extracted from the muscle of each species. The mtDNA was then sequenced using the Illumina NGS technique. The analysis of nutritional properties classified the fillets of the sampled species as lean or semi-fat, as they had a fat content of less than 3%, while the by-products showed a higher lipid content (2.7-5%). The protein percentage for all fillets was 22-23%, while for processing by-products, the protein concentration was 18-19% for all species. Rheological analyses showed an increase in viscosity in saline solution in all species, indicating their potential suitability for industrial processing. High-quality and quantity complete mtDNA was extracted from all analyzed species. The complete mitochondrial genome sequences were successfully obtained and annotated. The results of this study suggest that all analyzed species are suitable for both human consumption and feed production. The sequencing of the complete mtDNA and its availability in international databases will be useful for accurate phylogenetic analysis and proper species identification, even in prepared and processed products. Underutilized fish species represent an important economic resource. Encouraging their consumption could limit the phenomenon of overfishing, protecting marine biodiversity. Furthermore, the valorization of these species will increase national fish production, supporting the local economy, cultural, and gastronomic tradition, and optimizing the exploitation of Mediterranean resources in accordance with the CFP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mtDNA" title="mtDNA">mtDNA</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20analysis" title=" nutritional analysis"> nutritional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20fisheries" title=" sustainable fisheries"> sustainable fisheries</a>, <a href="https://publications.waset.org/abstracts/search?q=underutilized%20fish%20species" title=" underutilized fish species"> underutilized fish species</a> </p> <a href="https://publications.waset.org/abstracts/188888/valorization-of-underutilized-fish-species-through-a-multidisciplinary-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188888.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">30</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
