<p class="card-text"><strong>Abstract:</strong></p> <em>Jatropha curcas</em> is a perennial oleaginous plant that is currently considered an energy crop with high potential as an environmentally sustainable biofuel. During the last decades, research in biofuels has grown in tropical and subtropical regions in Latin America. However, as far we know, there are no reports on the growth and yield patterns of <em>Jatropha curcas</em> under the specific agro climatic scenarios of the State of Morelos, Mexico. This study presents the results of 52 months monitoring of 10 toxic and non-toxic ecotypes of <em>Jatropha curcas</em> (E1M, E2M, E3M, E4M, E5M, E6O, E7O, E8O, E9C, E10C) in an experimental plantation with minimum watering and fertilization resources. The main objective is to identify the ecotypes with the highest potential as biodiesel raw material in the select region, by developing experimental information. Specifically, we monitored biophysical and growth parameters, including plant survival and seed production (at the end of month 52), to study the performance of each ecotype and to establish differences among the variables of morphological growth, net seed oil content, and toxicity. To analyze the morphological growth, a statistical approach to the biophysical parameters was used; the net seed oil content -80 to 192 kg/ha- was estimated with the first harvest; and the toxicity was evaluated by examining the phorbol ester concentration (µg/L) in the oil extracted from the seeds. The comparison and selection of ecotypes was performed through a methodology developed based on the normalization of results. We identified four outstanding ecotypes (E1M, E2M, E3M, and E4M) that can be used to establish <em>Jatropha curcas</em> as energy crops in the state of Morelos for feasible agro-industrial production of biodiesel and other products related to the use of biomass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel%20production" title="biodiesel production">biodiesel production</a>, <a href="https://publications.waset.org/abstracts/search?q=Jatropha%20curcas" title=" Jatropha curcas"> Jatropha curcas</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20oil%20content" title=" seed oil content"> seed oil content</a>, <a href="https://publications.waset.org/abstracts/search?q=toxic%20and%20non-toxic%20ecotypes" title=" toxic and non-toxic ecotypes"> toxic and non-toxic ecotypes</a> </p> <a href="https://publications.waset.org/abstracts/106293/experimental-evaluation-of-10-ecotypes-of-toxic-and-non-toxic-jatropha-curcas-as-raw-material-to-produce-biodiesel-in-morelos-state-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> Foresight in Food Supply System in Bogota</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suarez-Puello%20Alejandro">Suarez-Puello Alejandro</a>, <a href="https://publications.waset.org/abstracts/search?q=Baquero-Ruiz%20Andr%C3%A9s%20F"> Baquero-Ruiz Andrés F</a>, <a href="https://publications.waset.org/abstracts/search?q=Suarez-Puello%20Rodrigo"> Suarez-Puello Rodrigo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the results of a foresight exercise which analyzes Bogota’s fruit, vegetable and tuber supply chain strategy- described at the Food Supply and Security Master Plan (FSSMP)-to provide the inhabitants of Bogotá, Colombia, with basic food products at a fair price. The methodology consisted of using quantitative and qualitative foresight tools such as system dynamics and variable selection methods to better represent interactions among stakeholders and obtain more integral results that could shed light on this complex situation. At first, the Master Plan is an input to establish the objectives and scope of the exercise. Then, stakeholders and their relationships are identified. Later, system dynamics is used to model product, information and money flow along the fruit, vegetable and tuber supply chain. Two scenarios are presented, discussing actions by the public sector and the reactions that could be expected from the whole food supply system. Finally, these impacts are compared to the Food Supply and Security Master Plan’s objectives suggesting recommendations that could improve its execution. This foresight exercise performed at a governmental level is intended to promote the widen the use of foresight as an anticipatory, decision-making tool that offers solutions to complex problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title="decision making">decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=foresight" title=" foresight"> foresight</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policies" title=" public policies"> public policies</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics" title=" system dynamics"> system dynamics</a> </p> <a href="https://publications.waset.org/abstracts/7898/foresight-in-food-supply-system-in-bogota" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7898.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">439</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">91</span> Left Atrial Appendage Occlusion vs Oral Anticoagulants in Atrial Fibrillation and Coronary Stenting.

The objective of the study was to determine whether left atrial appendage occlusion (LAAO) could be a feasible option and benefit these patients. To this end, we studied the impact of LAAO plus antiplatelet drugs vs oral anticoagulants (OAC) (including direct OAC) plus antiplatelet drugs in these patients’ long-term outcomes. Methods: The results of 207 consecutive patients with NVAF who underwent coronary stenting were analyzed. A total of 146 patients were treated with OAC (75 with acenocoumarol, 71 with direct OAC) while 61 underwent LAAO. The median follow-up was 35 months. Patients also received antiplatelet therapy as prescribed by their cardiologist. The study received the proper ethical oversight. Results: Age (mean 75.7 years), and the past medical history of stroke were similar in both groups. However, the LAAO group had more unfavorable characteristics (history of coronary artery disease [CHA2DS2-VASc], and significant bleeding [BARC ≥ 2] and HAS-BLED). The occurrence of major adverse events (death, stroke/transient ischemic events, major bleeding) and major cardiovascular events (cardiac death, stroke/transient ischemic attack, and myocardial infarction) were significantly higher in the OAC group compared to the LAAO group: 19.75% vs 9.06% (HR, 2.18; P = .008) and 6.37% vs 1.91% (HR, 3.34; P = .037), respectively. Conclusions: In patients with NVAF undergoing coronary stenting, LAAO plus antiplatelet therapy produced better long-term outcomes compared to treatment with OAC plus antiplatelet therapy despite the unfavorable baseline characteristics of the LAAO group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stents" title="stents">stents</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title=" atrial fibrillation"> atrial fibrillation</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulants" title=" anticoagulants"> anticoagulants</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20atrial%20appendage%20occlusion" title=" left atrial appendage occlusion"> left atrial appendage occlusion</a> </p> <a href="https://publications.waset.org/abstracts/183786/left-atrial-appendage-occlusion-vs-oral-anticoagulants-in-atrial-fibrillation-and-coronary-stenting-the-desafio-registry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183786.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">90</span> Fuzzy Expert Systems Applied to Intelligent Design of Data Centers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20M.%20Figueroa%20de%20la%20Cruz">Mario M.

Curutchet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work sets out to debate the tensions involved in the processes of contamination and self-purification in the urban space, particularly in the streams that run through the Buenos Aires metropolitan area. For much of their course, those streams are piped; their waters do not come into contact with the outdoors until they have reached deeply impoverished urban areas with high levels of environmental contamination. These are peripheral zones that, until thirty years ago, were marshlands and fields. They are now densely populated areas largely lacking in urban infrastructure. The Cárcova neighborhood, where this project is underway, is in the José León Suárez section of General San Martín country, Buenos Aires province. A stretch of José León Suarez canal crosses the neighborhood. Starting upstream, this canal carries pollutants due to the sewage and industrial waste released into it. Further downstream, in the neighborhood, domestic drainage is poured into the stream. In this paper, we formulate a hypothesis diametrical to the one that holds that these neighborhoods are the primary source of contamination, suggesting instead that in the stretch of the canal that runs through the neighborhood the stream’s waters are actually cleaned and the sediments accumulate pollutants. Indeed, the stretches of water that runs through these neighborhoods act as water processing plants for the metropolis. This project has studied the different organic-load polluting contributions to the water in a certain stretch of the canal, the reduction of that load over the course of the canal, and the incorporation of pollutants into the sediments. We have found that the surface water has considerable ability to self-purify, mostly due to processes of sedimentation and adsorption. The polluting load is accumulated in the sediments where that load stabilizes slowly by means of anaerobic processes. In this study, we also investigated the risks of sediment management and the use of the processes studied here in controlled conditions as tools of environmental restoration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title="bioremediation">bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutants" title=" pollutants"> pollutants</a>, <a href="https://publications.waset.org/abstracts/search?q=sediments" title=" sediments"> sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20streams" title=" urban streams"> urban streams</a> </p> <a href="https://publications.waset.org/abstracts/21295/accumulation-of-pollutants-self-purification-and-impact-on-peripheral-urban-areas-a-case-study-in-shantytowns-in-argentina" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21295.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">441</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">88</span> Effect of Silver Nanoparticles in Temperature Polarization of Distillation Membranes for Desalination Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lopez%20J.">Lopez J.</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrvar%20M."> Mehrvar M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Quinones%20E."> Quinones E.</a>, <a href="https://publications.waset.org/abstracts/search?q=Suarez%20A."> Suarez A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Romero%20C."> Romero C.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Membrane Distillation is an emerging technology that uses thermal and membrane steps for the desalination process to get drinking water.

International cooperation is necessary to solve this problem because cybercrime knows no borders and often involves multiple jurisdictions, being related to organised crime. The purpose of this article is to analyse international cooperation in the investigation and prosecution of cybercrime, focusing on the framework of the Regulation of the European Union Agency for Law Enforcement Cooperation (EUROPOL), cooperation that takes place between police authorities from different countries. It examines the legal and operational mechanisms in place to facilitate international cooperation in Europe in this area and assesses their effectiveness in the fight against cybercrime. In addition, the study of a Spanish investigation where cooperation with EUROPOL took place will be examined, analyzing how international cooperation was carried out to investigate and track down criminals. Lessons learned from this case will be discussed and recommendations for improving international cooperation in the fight against cybercrime will be proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Europol" title="Europol">Europol</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20cooperation" title=" international cooperation"> international cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=cybercrime" title=" cybercrime"> cybercrime</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20crime" title=" computer crime"> computer crime</a>, <a href="https://publications.waset.org/abstracts/search?q=law" title=" law"> law</a> </p> <a href="https://publications.waset.org/abstracts/182100/cybercrime-international-police-cooperation-with-europol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182100.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">66</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">83</span> Quantum Kernel Based Regressor for Prediction of Non-Markovianity of Open Quantum Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Tancara">Diego Tancara</a>, <a href="https://publications.waset.org/abstracts/search?q=Raul%20Coto"> Raul Coto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariel%20Norambuena"> Ariel Norambuena</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoseein%20T.%20Dinani"> Hoseein T.

Kernel-based quantum machine learning models are paradigmatic examples where the kernel involves quantum states, and the Gram matrix is calculated from the overlapping between these states. With the kernel at hand, a regular machine learning model is used for the learning process. In this paper we investigate the quantum support vector machine and quantum kernel ridge models to predict the degree of non-Markovianity of a quantum system. We perform digital quantum simulation of amplitude damping and phase damping channels to create our quantum dataset. We elaborate on different kernel functions to map the data and kernel circuits to compute the overlapping between quantum states. We observe a good performance of the models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum" title="quantum">quantum</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=kernel" title=" kernel"> kernel</a>, <a href="https://publications.waset.org/abstracts/search?q=non-markovianity" title=" non-markovianity"> non-markovianity</a> </p> <a href="https://publications.waset.org/abstracts/165769/quantum-kernel-based-regressor-for-prediction-of-non-markovianity-of-open-quantum-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165769.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">180</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">82</span> Software Obsolescence Drivers in Aerospace: An Industry Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Gonz%C3%A1lez%20Mu%C3%B1oz">Raúl González Muñoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Shehab"> Essam Shehab</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Weinitzke"> Martin Weinitzke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Fowler"> Chris Fowler</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Baguley"> Paul Baguley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software applications have become crucial for the aerospace industry, providing a wide range of functionalities and capabilities. However, due to the considerable time difference between aircraft and software life cycles, obsolescence has turned into a major challenge for industry in last decades. This paper aims to provide a view on the different causes of software obsolescence within aerospace industry, as well as a perception on the importance of each of them. The key research question addressed is what drives software obsolescence in the aerospace industry, managing large software application portfolios. This question has been addressed by conducting firstly an in depth review of current literature and secondly by arranging an industry workshop with professionals from aerospace and consulting companies. The result is a set of drivers of software obsolescence, distributed among three different environments and several domains. By incorporating monitoring methodologies to assess those software obsolescence drivers, benefits in maintenance efforts and operations disruption avoidance are expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace%20industry" title="aerospace industry">aerospace industry</a>, <a href="https://publications.waset.org/abstracts/search?q=obsolescence%20drivers" title=" obsolescence drivers"> obsolescence drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20lifecycle" title=" software lifecycle"> software lifecycle</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20obsolescence" title=" software obsolescence"> software obsolescence</a> </p> <a href="https://publications.waset.org/abstracts/72049/software-obsolescence-drivers-in-aerospace-an-industry-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72049.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">411</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">81</span> Heavy Metals Estimation in Coastal Areas Using Remote Sensing, Field Sampling and Classical and Robust Statistic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Castillo-L%C3%B3pez">Elena Castillo-López</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda"> Raúl Pereda</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis"> Julio Manuel de Luis</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez"> Rubén Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Pi%C3%B1a"> Felipe Piña</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sediments are an important source of accumulation of toxic contaminants within the aquatic environment.

Providing operational police commanders with effective and efficient tools, providing analytical capacity to reduce criminal opportunities, must be a priority. Given the intimate connection of crimes and infractions to the environment, law enforcement institutions must respond proactively to changing circumstances of anti-norm behaviors. To this end, it has been intended to analyze the antisocial spatial distribution of the city of Móstoles, trying to identify those spatiotemporal patterns that occur to anticipate their commission through the planning of dynamic preventive strategies. The application of GIS offers alternative analytical approaches to the different problems that underlie the development of life in society, focusing resources on those places with the highest concentration of incidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20analysis" title="data analysis">data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=police%20organizations" title=" police organizations"> police organizations</a>, <a href="https://publications.waset.org/abstracts/search?q=police%20prevention" title=" police prevention"> police prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20information%20systems" title=" geographic information systems"> geographic information systems</a> </p> <a href="https://publications.waset.org/abstracts/182101/improving-law-enforcement-strategies-through-geographic-information-systems-a-spatio-temporal-analysis-of-antisocial-activities-in-mostoles-2022" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182101.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">50</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">79</span> Economic Design of a Quality Control Chart for the Proportion of Defective Items</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Encarnaci%C3%B3n%20%C3%81lvarez-Verdejo">Encarnación Álvarez-Verdejo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Amor-Pulido"> Raúl Amor-Pulido</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20J.%20Moya-Fern%C3%A1ndez"> Pablo J.

The evaluation of the quality of products and services is an important topic, but the reduction of the cost of the implantation of the statistical quality control also has important benefits for the companies. For this reason, it is important to implement a economic design for the various steps included into the statistical quality control. In this paper, we describe some relevant aspects related to the economic design of a quality control chart for the proportion of defective items.

Ethiopia is 15th among the 27 MDR-TB high-burden countries. A case control study was conducted at St. Peter Hospital and five health centers in Addis Ababa. Cases were MDR-TB patients who were in treatment at St. Peter Hospital during the study period. Controls were patients who were on first-line anti-TB treatment and were registered as cured or having completed treatment in the period 9 April 2009– 28 February 2010, in five health centers. A structured interview questionnaire was used to assess factors that could potentially be associated with the occurrence of MDR-TB. Factors that were significantly associated with MDR-TB: drug side effects during first-line treatment (adjusted odds ratio (AOR): 4.5, 95% CI; 1.9 - 10.5); treatment not directly observed by a health worker (AOR = 11.7, 95% CI; 4–34.3); and retreatment with the Category II regimen (P = 0.000). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adherence%20to%20TB%20treatment" title="adherence to TB treatment">adherence to TB treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=MDR-TB" title=" MDR-TB"> MDR-TB</a>, <a href="https://publications.waset.org/abstracts/search?q=TB%20treatment" title=" TB treatment"> TB treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=TB%20treatment%20regimens" title=" TB treatment regimens "> TB treatment regimens </a> </p> <a href="https://publications.waset.org/abstracts/2872/determinants-of-multidrug-resistant-tuberculosis-in-patients-who-underwent-first-line-treatment-in-addis-ababa-a-case-control-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2872.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">501</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">76</span> Histochemistry of Intestinal Enzymes of Juvenile Dourado Salminus brasiliensis Fed Bovine Colostrum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debora%20B.%20Moretti">Debora B.

The intestinal enzymes acid and alkaline phosphatase (ACP and ALP, respectively), non-specific esterase (NSE), lipase (LIP), dipeptidyl aminopeptidase IV (DAP IV) and leucine aminopeptidase (LAP) were studied using histochemistry in four intestinal segments (S1, S2, S3 and posterior intestine). Weak proteolitic activity was observed in all intestinal segments for DAP IV and LAP. The activity of NSE and LIP was also weak in all intestines, except for the moderate activity of NSE in the S2 of 20% LBC group after 30 days and in the S1 of 0% LBC group after 60 days. The ACP was detected only in the S2 and S3 of the 10% LBC group after 30 days. Moderate and strong staining was observed in the first three intestinal segments for ALP and weak activity in the posterior intestine. The activity of DAP IV, LAP and ALP were also present in the cytoplasm of the enterocytes. In the present results, bovine colostrum feeding did not cause alterations in activity of intestinal enzymes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carnivorous%20fish" title="carnivorous fish">carnivorous fish</a>, <a href="https://publications.waset.org/abstracts/search?q=enterocyte" title=" enterocyte"> enterocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20epithelium" title=" intestinal epithelium"> intestinal epithelium</a>, <a href="https://publications.waset.org/abstracts/search?q=teleost" title=" teleost"> teleost</a> </p> <a href="https://publications.waset.org/abstracts/9534/histochemistry-of-intestinal-enzymes-of-juvenile-dourado-salminus-brasiliensis-fed-bovine-colostrum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9534.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">329</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">75</span> Tool Damage and Adhesion Effects in Turning and Drilling of Hardened Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chris%20M.%20Taylor">Chris M.

In a finish turning process, it was seen that surface roughness and tool flank wear followed very different trends against cutting time. The suggested explanation for this behaviour is that the profile cut into the workpiece surface is determined by the tool’s cutting edge profile. It is shown that the profile appearing on the cut surface changes rapidly over time, so the profile of the tool cutting edge should also be changing rapidly. Workpiece material adhered onto the cutting tool, which is also known as a built-up edge, is a phenomenon which could explain the observations made. In terms of tool damage modes, workpiece material adhesion is believed to have contributed to tool wear in examples provided from finish turning, thread turning and drilling. Additionally, evidence of tool fracture and tool abrasion were recorded. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turning" title="turning">turning</a>, <a href="https://publications.waset.org/abstracts/search?q=drilling" title=" drilling"> drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion" title=" adhesion"> adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20steels" title=" hard steels"> hard steels</a> </p> <a href="https://publications.waset.org/abstracts/52027/tool-damage-and-adhesion-effects-in-turning-and-drilling-of-hardened-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52027.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">342</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">74</span> Experimental Approach for Determining Hemi-Anechoic Characteristics of Engineering Acoustical Test Chambers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Montoya-Ospina">Santiago Montoya-Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20E.%20Jim%C3%A9nez-Mej%C3%ADa"> Raúl E.

For this study we used semantic differential, a method proposed in the sixties by Osgood, Suci and Tannenbaum, starts from the assumption that under each particular way of perceiving the world, in each singular idea, there is a common cultural meaning that organizes experiences. In relation to these shared symbolic dimension, this method has had significant results, as it focuses on breaking down the meaning of certain significant acts into series of statements that place the subjects in front of some concepts. In Colombia, in 2016, a tool was designed to measure the meaning of a multimodal production, specially the acts of sense of transmedia productions that managed to receive funds from the Ministry of ICT of Colombia, and also, to analyze predictable patterns that can be found in calls and funds aimed at the production of culture in Colombia, in the context of the peace agreement, as a request for expressions from a hegemonic place, seeking to impose a worldview. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semantic%20differential" title="semantic differential">semantic differential</a>, <a href="https://publications.waset.org/abstracts/search?q=semiotics" title=" semiotics"> semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=transmedia" title=" transmedia"> transmedia</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20analysis%20of%20discourse" title=" critical analysis of discourse"> critical analysis of discourse</a> </p> <a href="https://publications.waset.org/abstracts/76655/multimodal-discourse-logic-of-the-analysis-of-transmedia-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76655.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">205</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">72</span> Main Cause of Children's Deaths in Indigenous Wayuu Community from Department of La Guajira: A Research Developed through Data Mining Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaura%20Esther%20Solano%20N%C3%BA%C3%B1ez">Isaura Esther Solano Núñez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Suarez"> David Suarez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this research is to discover what causes death in children of the Wayuu community, and deeply analyze those results in order to take corrective measures to properly control infant mortality.

In this way, the government, through competent authorities, may develop prevention policies and the right measures to avoid an increase of this tragic fact. The methodology used to develop this investigation is data mining, which consists in gaining and examining large amounts of data to produce new and valuable information. Through this technique it has been possible to determine that the child population is dying mostly from malnutrition.

Unmanned Aerial Vehicle (UAV) techniques have become more popular than traditional techniques. Specifically, UAV Photogrammetry allows time and cost savings. The development of this technology has permitted the use of low-cost thermal sensors in UAVs. The representation of 3D thermal models with this type of equipment is in continuous evolution. The direct processing of thermal images usually leads to errors and inaccurate results. A methodology is proposed for the generation of 3D thermal models using dual sensors, which involves the application of visible Red-Blue-Green (RGB) and thermal images in parallel. Hence, the RGB images are used as the basis for the generation of the model geometry, and the thermal images are the source of the surface temperature information that is projected onto the model. Mining/industrial facilities representations that are obtained can be used for inspection activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20thermography" title="aerial thermography">aerial thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20processing" title=" data processing"> data processing</a>, <a href="https://publications.waset.org/abstracts/search?q=drone" title=" drone"> drone</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost" title=" low-cost"> low-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=point%20cloud" title=" point cloud"> point cloud</a> </p> <a href="https://publications.waset.org/abstracts/148302/application-methodology-for-the-generation-of-3d-thermal-models-using-uav-photogrammety-and-dual-sensors-for-miningindustrial-facilities-inspection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148302.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">143</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">70</span> A Numerical Investigation of Flow Maldistribution in Inlet Header Configuration of Plate Fin Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Appasaheb%20Raul">Appasaheb Raul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical analysis of a plate fin heat exchanger accounting for the effect of fluid flow maldistribution on the inlet header configuration of the heat exchanger is investigated. It is found that the flow maldistribution is very significant in normal to the flow direction. Various inlet configuration has been studied for various Reynolds Number. By the study, a modified header configuration is proposed and simulated. The two-dimensional parameters are used to evaluate the flow non-uniformity in the header, global flow maldistribution parameter (Sg), and Velocity Ratio (θ). A series of velocity vectors and streamline graphs at different cross-section are achieved and studied qualitatively with experimental results in the literature. The numerical result indicates that the flow maldistribution is serious in the conventional header while in the improved configuration less maldistribution occurs. The flow maldistribution parameter (Sg) and velocity ratio (θ) is reduced in improved configuration. The vortex decreases compared to that of the conventional configuration so the energy and pressure loss is reduced. The improved header can effectively enhance the efficiency of plate fin heat exchanger and uniformity of flow distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20flow%20maldistribution%20parameter" title="global flow maldistribution parameter">global flow maldistribution parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=Sg" title=" Sg"> Sg</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20ratio" title=" velocity ratio"> velocity ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20fin%20heat%20exchanger" title=" plate fin heat exchanger"> plate fin heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent%2014.5" title=" fluent 14.5"> fluent 14.5</a> </p> <a href="https://publications.waset.org/abstracts/34028/a-numerical-investigation-of-flow-maldistribution-in-inlet-header-configuration-of-plate-fin-heat-exchanger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34028.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">525</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">69</span> Market Competition and the Adoption of Clean Technology: Evidence from the Taxi Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Bajo-Buenestado">Raúl Bajo-Buenestado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the impact of the intensity of market competition on firms' willingness to adopt green technologies —which has become particularly relevant in the light of the debate on whether competition policies should be relaxed to achieve certain environmental targets. We exploit the staggered rollout of different rail-hailing platforms (most notably, Uber) across different metropolitan areas in Spain as a natural experiment that provides time and city-specific exogenous variation in the intensity of competition to study the impact on taxi drivers' decisions to purchase “green” or “dirty” vehicles. It was shown that the entry of these platforms significantly increased the takeout of green vehicles among professional drivers in incumbent (dominant) conventional taxi companies and decreased that of dirty vehicles. The exact opposite effect is observed in the cities where these platforms were extremely unlikely to enter. Back of the envelope calculations suggest that the entry of Uber is associated with an extra green vehicle purchase in every four among taxi drivers, resulting in a substantial drop in the level of emissions from the taxi fleet —still mostly dominated diesel vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technological%20change" title="technological change">technological change</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20technology%20adoption" title=" green technology adoption"> green technology adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20competition" title=" market competition"> market competition</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20of%20technology" title=" diffusion of technology"> diffusion of technology</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20externalities" title=" environmental externalities"> environmental externalities</a> </p> <a href="https://publications.waset.org/abstracts/135426/market-competition-and-the-adoption-of-clean-technology-evidence-from-the-taxi-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135426.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Analysis of the Accuracy of Earth Movement with Drone Surveys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda%20Garc%C3%ADa">Raúl Pereda García</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis%20Ruiz"> Julio Manuel de Luis Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Castillo%20L%C3%B3pez"> Elena Castillo López</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez%20%C3%81lvarez"> Rubén Pérez Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Pi%C3%B1a%20Garc%C3%ADa"> Felipe Piña García</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New technologies for the capture of point clouds have experienced a great advance in recent years. In this way, its use has been extended in geomatics, providing measurement solutions that have been popularized without there being, many times, a detailed study of its accuracy. This research focuses on the study of the viability of topographic works with drones incorporating different sensors sensitive to the visible spectrum. The fundamentals have been applied to a road, located in Cantabria (Spain), where a platform extension and the reform of a riprap were being constructed. A total of six flights were made during two months, all of them with GPS as part of the photogrammetric process, and the results were contrasted with those measured with total station. The obtained results show that the choice of the camera and the planning of the flight have an important impact on the accuracy. In fact, the representations with a level of detail corresponding to 1/1000 scale are admissible, depending on the existing vegetation, and obtaining better results in the area of the riprap. This set of techniques is, therefore, suitable for the control of earthworks in road works but with certain limitations which are exposed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drone" title="drone">drone</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20movement%20control" title=" earth movement control"> earth movement control</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20position%20system" title=" global position system"> global position system</a>, <a href="https://publications.waset.org/abstracts/search?q=surveying%20technology." title=" surveying technology.

The suggestion is made that a hotel’s fair treatment (in terms of distributive, procedural, and interactional justice) toward customers will be appreciated by the employees, who will reciprocate in kind by favouring the hotel with increased customer-oriented behaviours (COBs). Data were collected from 204 employees at eight upscale hotels in the Canary Islands (Spain). Unlike in the case of perceptions of distributive justice, results of structural equation modelling demonstrate that employees substantively react to interactional and procedural justice toward guests by engaging in customer-oriented behaviours (COBs). The findings offer new reasons why employees decide to engage in COBs, and they highlight potentially beneficial effects of fair treatment toward guests bring to hospitality through promoting COBs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotel%20guests%E2%80%99%20%28mis%29%20treatment" title="hotel guests’ (mis) treatment">hotel guests’ (mis) treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=customer-oriented%20behaviours" title=" customer-oriented behaviours"> customer-oriented behaviours</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20citizenship" title=" employee citizenship"> employee citizenship</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20justice" title=" organizational justice"> organizational justice</a>, <a href="https://publications.waset.org/abstracts/search?q=third-party%20observers" title=" third-party observers"> third-party observers</a>, <a href="https://publications.waset.org/abstracts/search?q=third-party%20intervention" title=" third-party intervention"> third-party intervention</a> </p> <a href="https://publications.waset.org/abstracts/4384/the-organizational-justice-citizenship-behavior-link-in-hotels-does-customer-orientation-matter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4384.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">273</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">66</span> Energy Analysis and Integration of the H₂ Production from Biomass Fast Pyrolysis and in Line Sorption Enhanced Steam Reforming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Comendador">P.

However, Sorption Enhanced Steam Reforming (SESR) is gaining attention as an alternative to the conventional SR since it allows obtaining higher H₂ yields and a purity near 100 % in the product stream. In this work, both alternatives were compared through an energy analysis. The processes were modeled with PRO II v.2021 software. First, general energy balances were carried out in order to identify the total energy requirements in a wide range of operating conditions. At H₂ yield optimum conditions for both processes (steam to biomass ratio of 2 and temperature of 600 ºC), the total energy requirement for the SR alternative is 936 kJ/kgH₂, whereas for the SESR alternative is 1134 kJ/kgH₂. Then, the energy needs were grouped into operation stages, aiming at identifying the energy sinks and sources of the processes. It was determined that the SESR alternative is more energy intensive due to the need for a calcination stage for regenerating the sorbent. Finally, a configuration of the SESR alternative with energy integration was developed in order to compensate for the energy demand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biomass%20valorization" title="Biomass valorization">Biomass valorization</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20capture" title=" CO₂ capture"> CO₂ capture</a>, <a href="https://publications.waset.org/abstracts/search?q=Energy%20analysis" title=" Energy analysis"> Energy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=H%E2%82%82%20production" title=" H₂ production"> H₂ production</a> </p> <a href="https://publications.waset.org/abstracts/165192/energy-analysis-and-integration-of-the-h2-production-from-biomass-fast-pyrolysis-and-in-line-sorption-enhanced-steam-reforming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165192.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">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Geometric Contrast of a 3D Model Obtained by Means of Digital Photogrametry with a Quasimetric Camera on UAV Classical Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis%20Ruiz">Julio Manuel de Luis Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Sedano%20Cibri%C3%A1n"> Javier Sedano Cibrián</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez%20%C3%81lvarez"> Rubén Pérez Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda%20Garc%C3%ADa"> Raúl Pereda García</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Diego%20Soroa"> Cristina Diego Soroa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the use of drones has been extended to practically any human activity. One of the main applications is focused on the surveying field. In this regard, software programs that process the images captured by the sensor from the drone in an almost automatic way have been developed and commercialized, but they only allow contrasting the results through control points. This work proposes the contrast of a 3D model obtained from a flight developed by a drone and a non-metric camera (due to its low cost), with a second model that is obtained by means of the historically-endorsed classical methods. In addition to this, the contrast is developed over a certain territory with a significant unevenness, so as to test the model generated with photogrammetry, and considering that photogrammetry with drones finds more difficulties in terms of accuracy in this kind of situations. Distances, heights, surfaces and volumes are measured on the basis of the 3D models generated, and the results are contrasted. The differences are about 0.2% for the measurement of distances and heights, 0.3% for surfaces and 0.6% when measuring volumes. Although they are not important, they do not meet the order of magnitude that is presented by salespeople. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20topographic" title=" classical topographic"> classical topographic</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20tridimensional" title=" model tridimensional"> model tridimensional</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title=" photogrammetry"> photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=Uav." title=" Uav.

These projects usually involve the performance of a group of tasks (named roles) that have to be distributed among the partners. Thus, an allocation/matching problem arises that will be referred to as Role-Partner Allocation problem. In real life this situation is addressed by negotiation between partners in order to reach <em>ad hoc</em> agreements. Besides taking a long time and being hard work, both historical evidence and economic analysis show that such approach is not recommended. Instead, the allocation process should be automated by means of a centralized matching scheme. However, as a preliminary step to start the search for such a matching mechanism (or even the development of a new one), the problem and its core components must be specified. To this end, this paper establishes (i) the definition of the problem and its constraints, (ii) the key features of the involved elements (i.e., roles and partners); and (iii) how to create preference lists both for roles and partners. Only this way it will be possible to conduct subsequent methodological research on the solution method.      <p class="card-text"><strong>Keywords:</strong> <a
