Azadirachta indica, known as Neem, has been traditionally used in medicinal practices. Due to the presence of bioactive substances such as nimbolide, azadirachtin, and gedunin, Neem offers a variety of medicinal properties, including anti-inflammatory and antioxidant properties. Through its effect on pathological inflammatory processes, supplementation with it could alleviate the symptoms of rheumatoid arthritis (RA). Methods: This research aimed to assess Neem seed oil's impact on rats with adjuvant arthritis. Three doses in monotherapy and two in combination with methotrexate (MTX) have been studied, and their effect was compared. Neem p.o. doses of 100, 200, and 300 mg/kg and MTX p.o. doses of 0.3 mg/kg were examined. After clinical parameters assessment, biochemical analysis was performed in plasma. Results: During the acute phase of the experimental arthritis (Day21), levels of MMP-9, MCP-1, and cytokines IL-1beta and IL-17A were measured. The positive results of inflammatory mediators evaluation in plasma encourage additional analysis also in related tissues to prove if Neem seed oil can be used as an adjuvant therapy for RA. Conclusion: In this study, the combination therapy of Neem with MTX was the most effective of all therapies investigated.

The objective of this work is to investigate the hot airflow effect during the growth of MAPbI₃ films using the spin-coating process on their structural, optical and morphological proprieties. The experimental results show that many physical proprieties of the perovskite strongly depend on the air flow temperature and the optimization which has a beneficial effect on the perovskite quality. In fact, a clear improvement of the crystallinity and the crystallite size of MAPbI₃ perovskite is demonstrated by the XRD analyses, when the airflow temperature is increased up to 100°C. Alternatively, as far as the surface morphology is concerned, SEM micrographs show that significant homogenous nucleation, uniform surface distribution and pin holes free with highest surface coverture of 98% are achieved when the airflow temperature reaches 100°C. At this temperature, the improvement is also observed when considering the optical properties of the films. By contrast, a remarkable degradation of the MAPbI₃ perovskites associated to the PbI₂ phase formation is noticed, when the hot airflow temperature is higher than 100°C, especially 300°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20air%20flow" title="hot air flow">hot air flow</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallinity" title=" crystallinity"> crystallinity</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coverage" title=" surface coverage"> surface coverage</a>, <a href="https://publications.waset.org/abstracts/search?q=perovskite%20morphology" title=" perovskite morphology"> perovskite morphology</a> </p> <a href="https://publications.waset.org/abstracts/102435/hot-air-flow-annealing-of-mapbi3-perovskite-structural-and-optical-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102435.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">93</span> Integrating Service Learning into a Business Analytics Course: A Comparative Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Egilmez">Gokhan Egilmez</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Hatfield"> Erika Hatfield</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Turner"> Julie Turner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we investigated the impacts of service-learning integration on an undergraduate level business analytics course from multiple perspectives, including academic proficiency, community awareness, engagement, social responsibility, and reflection.

This curve provides information about the performance of petroleum in terms of its cuts. The experiment is performed in a few days. Techniques are used to determine the properties faster with a software that calculates the distillation curve when a little information about crude oil is known. In order to evaluate the accuracy of distillation curve prediction, eight points of the TBP curve and specific gravity curve (348 K and 523 K) were inserted into the HYSYS Oil Manager, and the extended curve was evaluated up to 748 K. The methods were able to predict the curve with the accuracy of 0.6%-9.2% error (Software X ASTM), 0.2%-5.1% error (Software X Spaltrohr). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distillation%20curve" title="distillation curve">distillation curve</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20distillation" title=" petroleum distillation"> petroleum distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=true%20boiling%20point%20curve" title=" true boiling point curve"> true boiling point curve</a> </p> <a href="https://publications.waset.org/abstracts/68293/comparison-of-the-distillation-curve-obtained-experimentally-with-the-curve-extrapolated-by-a-commercial-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68293.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">89</span> Effect of Outliers in Assessing Significant Wave Heights Through a Time-Dependent GEV Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Calder%C3%B3n-Vega">F.

In this study, some extremely large wave heights recorded in NOAA buoys (National Data Buoy Center, noaa.gov) are used to investigate their effect in the prediction of future wave heights associated with given return periods. Extreme waves are predicted through a time-dependent model based on the so-called generalized extreme value distribution. It is found that the outliers do affect the estimated wave heights. It is concluded that a detailed inspection of outliers is envisaged to determine whether they are real recorded values since this will impact defining design wave heights for coastal protection purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GEV%20model" title="GEV model">GEV model</a>, <a href="https://publications.waset.org/abstracts/search?q=non-stationary" title=" non-stationary"> non-stationary</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonality" title=" seasonality"> seasonality</a>, <a href="https://publications.waset.org/abstracts/search?q=outliers" title=" outliers"> outliers</a> </p> <a href="https://publications.waset.org/abstracts/147991/effect-of-outliers-in-assessing-significant-wave-heights-through-a-time-dependent-gev-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147991.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">88</span> Finite Dynamic Programming to Decision Making in the Use of Industrial Residual Water Treatment Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Vega%20Camacho">Oscar Vega Camacho</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Vargas"> Andrea Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ellery%20Ariza"> Ellery Ariza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the application of finite dynamic programming, specifically the "Markov Chain" model, as part of the decision making process of a company in the cosmetics sector located in the vicinity of Bogota DC.

Our method replicates parameter values from observed trajectory curves, enhancing the accuracy of predictions when compared to traditional calibration techniques. Through the use of simulated data, we train the models to predict epidemiological parameters more accurately. Two primary approaches were explored: one where the number of susceptible, infected, and recovered individuals is fully known, and another using only the number of infected individuals.

Currently it is important to understand the successful way to implement this philosophy and try to identify barriers and enablers to the sustainability of lean healthcare. The main purpose of this research is to identify the barriers and enablers in the implementation of Lean Healthcare based on case studies of Colombian healthcare centers. In order to do so, we conducted semi-structured interviews based on a maturity model. The main results indicate that the success of Lean implementation depends on its adaptation to contextual factors. In addition, in the Colombian context were identified new factors such as organizational culture, management models, integration of the care and administrative departments and triple helix relationship. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barriers" title="barriers">barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=enablers" title=" enablers"> enablers</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation" title=" implementation"> implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20healthcare" title=" lean healthcare"> lean healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/48144/lean-healthcare-barriers-and-enablers-in-the-colombian-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48144.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">366</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> A Location Routing Model for the Logistic System in the Mining Collection Centers of the Northern Region of Boyacá-Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erika%20Ru%C3%ADz">Erika Ruíz</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Amaya"> Luis Amaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Carre%C3%B1o"> Diego Carreño</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study is to design a mathematical model for the logistics of mining collection centers in the northern region of the department of Boyacá (Colombia), determining the structure that facilitates the flow of products along the supply chain.

First, the audio signal was obtained from a mobile device and processed in Matlab to modify it, adding noise or other desired effects. Then, the processed signal was passed through a preamplifier to increase its amplitude to a level suitable for further amplification through a power amplifier, which was part of the current driver circuit of the Tesla coil. To get the Tesla coil to generate music, a circuit capable of modulating and generating the audio signal by manipulating electrical discharges was used. To visualize and listen to these discharges, a small Faraday cage was built to attenuate the external electric fields. Finally, the implementation of the musical Tesla coil was concluded. However, it was observed that the audio signal volume was very low, and the components used heated up quickly. Due to these limitations, it was determined that the project could not be connected to power for long periods of time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesla%20coil" title="Tesla coil">Tesla coil</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma" title=" plasma"> plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20signals" title=" electrical signals"> electrical signals</a>, <a href="https://publications.waset.org/abstracts/search?q=GNU%20Radio" title=" GNU Radio"> GNU Radio</a> </p> <a href="https://publications.waset.org/abstracts/170861/musical-tesla-coil-with-faraday-box-controlled-by-a-gnu-radio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170861.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">97</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> Application of Sensory Thermography on Workers of a Wireless Industry in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Camargo%20Wilson">Claudia Camargo Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Javier%20de%20la%20Vega%20Bustillos"> Enrique Javier de la Vega Bustillos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Everardo%20Olgu%C3%ADn%20Tiznado"> Jesús Everardo Olguín Tiznado</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Andr%C3%A9s%20L%C3%B3pez%20Barreras"> Juan Andrés López Barreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20K.%20Enriquez"> Sandra K.

Unfortunately, the vast majority of these evaluations are made by software enthusiasts who publish their results on blogs or on non-academic websites and always with the same evaluation methodology. Similarly, academics who have carried out this type of analysis from a scientific approach, the majority, make their analysis within the same methodology as well the empirical authors. This paper is based on the interest of finding answers to questions that many users of this type of tools have been asking over the years, such as, to know if the tool truly test and evaluate every vulnerability that it ensures do, or if the tool, really, deliver a real report of all the vulnerabilities tested and exploited. This kind of questions have also motivated previous work but without real answers. The aim of this paper is to show results that truly answer, at least on the tested tools, all those unanswered questions. All the results have been obtained by changing the common model of benchmarking used for all those previous works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title="cybersecurity">cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=IDS" title=" IDS"> IDS</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20scanners" title=" web scanners"> web scanners</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20vulnerabilities" title=" web vulnerabilities"> web vulnerabilities</a> </p> <a href="https://publications.waset.org/abstracts/70338/benchmarking-of-pentesting-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70338.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">319</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">78</span> Using Wiki for Enhancing the Knowledge Transfer to Newcomers: An Experience Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hualter%20Oliveira%20Barbosa">Hualter Oliveira Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Raquel%20Feitosa%20do%20Vale%20Cunha"> Raquel Feitosa do Vale Cunha</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Muniz%20dos%20Santos"> Erika Muniz dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Belmira%20Souza"> Fernanda Belmira Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Sousa"> Fabio Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Henrique%20Pascareli"> Luis Henrique Pascareli</a>, <a href="https://publications.waset.org/abstracts/search?q=Franciney%20de%20Oliveira%20Lima"> Franciney de Oliveira Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Cl%C3%A1udia%20Reis%20da%20Silva"> Ana Cláudia Reis da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Christiane%20Moreira%20de%20Almeida"> Christiane Moreira de Almeida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software development is intrinsic human-based knowledge-intensive.

In this work, thanks to the comparison of archaeological, historical and epigraphic sources, the evolution and changes that occurred in the cities and areas around the limes were analysed. As of now, there are many studies relative to the roman imperial period, however there are not that many analysing the evolution of the limes from the Islamic conquest to the modern day, comparing the ancient, byzantine, islamic and contemporary periods, understanding the significance of the limes, it s role and the cities and commerce that were defined by it in north Africa. Using modern methods of remote sensing and landscape archaeology, a georeferencing of the area documented in the thirties of the last century by French military aviation colonel Jean Baradez was created, showing that the limes africanus had survived the fall of the roman empire and continued to be important also for the Islamic dynasties that came later, even until the italo-turkish war and the Italian conquest of Libya. With this research we wish to demonstrate the continuation through time of the limes africanus and whether today it exists still or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Limes%20Tripolitanus" title="Limes Tripolitanus">Limes Tripolitanus</a>, <a href="https://publications.waset.org/abstracts/search?q=Muslim" title=" Muslim"> Muslim</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Africa" title=" North Africa"> North Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=Romans" title=" Romans"> Romans</a> </p> <a href="https://publications.waset.org/abstracts/125945/limes-africanus-tribes-romans-and-islamic-dynasties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125945.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">202</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> Voice Signal Processing and Coding in MATLAB Generating a Plasma Signal in a Tesla Coil for a Security System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jimenez">Juan Jimenez</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Yambay"> Erika Yambay</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Pilco"> Dayana Pilco</a>, <a href="https://publications.waset.org/abstracts/search?q=Brayan%20Parra"> Brayan Parra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an investigation of voice signal processing and coding using MATLAB, with the objective of generating a plasma signal on a Tesla coil within a security system.

Any multi-party computation can be realised with OT as a building block. XOR oblivious transfer (XOT) is a variant where the sender Alice has two bits, and a receiver, Bob, obtains either the first bit, the second bit, or their XOR. Bob should not learn anything more than this, and Alice should not learn what Bob has learned. Perfect quantum OT with information-theoretic security is known to be impossible. We determine the smallest possible cheating probabilities for unrestricted dishonest parties in non-interactive quantum XOT protocols using symmetric pure states and present an optimal protocol which outperforms classical protocols. We also "reverse" this protocol so that Bob becomes the sender of a quantum state and Alice the receiver who measures it while still implementing oblivious transfer from Alice to Bob. Cheating probabilities for both parties stay the same as for the unreversed protocol. We optically implemented both the unreversed and the reversed protocols and cheating strategies, noting that the reversed protocol is easier to implement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oblivious%20transfer" title="oblivious transfer">oblivious transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20protocol" title=" quantum protocol"> quantum protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=XOR" title=" XOR"> XOR</a> </p> <a href="https://publications.waset.org/abstracts/168274/non-interactive-xor-quantum-oblivious-transfer-optimal-protocols-and-their-experimental-implementations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168274.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">126</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">73</span> Mathematical Games with RPG and Sci-Fi Elements to Enhance Motivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Moll%20Lopez">Santiago Moll Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Erica%20Vega%20Fleitas"> Erica Vega Fleitas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dolors%20Rosello%20Ferragud"> Dolors Rosello Ferragud</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Manuel%20Sanchez%20Ruiz"> Luis Manuel Sanchez Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Antonio%20Mora%C3%B1o%20Fernandez"> Jose Antonio Moraño Fernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Game-based learning (GBL) is becoming popular in education.

This study aims to describe the social and economic impact of home sharing in Metro Manila from the perspective of hosts. A cross-sectional survey questionnaire consisting of five-point Likert items was administered to 120 hosts in Metro Manila. Kruskal-Wallis test, together with Dunn’s pairwise comparison, was used in the analysis of data. Results show that there is a significant difference in the median scores between increased awareness of Filipino food/heritage and the pursuit of enjoyable life in terms of social impact. Economic-wise, the respondents, did not perceive that their businesses as an additional source of income for the local government. These findings can be used for further exploratory studies and formulation of sustainable business policies conducive for the entrepreneurs and the hospitality industry alike. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bed-and-breakfast" title="bed-and-breakfast">bed-and-breakfast</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20sharing" title=" home sharing"> home sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=marketing" title=" marketing"> marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a> </p> <a href="https://publications.waset.org/abstracts/52633/social-and-economic-impact-of-home-sharing-in-metro-manila-hosts-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52633.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">323</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">71</span> Maturity Model for Agro-Industrial Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erika%20Tatiana%20Ruiz">Erika Tatiana Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilson%20Adarme%20Jaimes"> Wilson Adarme Jaimes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This abstract presents the methodology for improving the logistics processes of agricultural production units belonging to the coffee, cocoa, and fruit sectors, starting from the fundamental concepts and detailing each of the phases to carry out the diagnosis, which will be the basis for the formulation of its action plan and implementation of the maturity model. As a result of this work, the maturity model is formulated to improve logistics processes. This model seeks to: generate a progressive model that is useful for all productive units belonging to these sectors at the national level, regardless of their initial conditions, focus on the improvement of logistics processes as a strategy that contributes to improving the competitiveness of the agricultural sector in Colombia and spread the implementation of good logistics practices in postharvest in all departments of the country through autonomous tools. This model has been built through a series of steps that allow the evaluation and improvement of the logistics dimensions or indicators. The potential improvements for each dimension provide the foundation on which to advance to the next level. Within the maturity model, a methodology is indicated for the design and execution of strategies to improve its logistics processes, taking into account the current state of each production unit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroindustrial" title="agroindustrial">agroindustrial</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics" title=" logistics"> logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=maturity%20model" title=" maturity model"> maturity model</a>, <a href="https://publications.waset.org/abstracts/search?q=processes" title=" processes"> processes</a> </p> <a href="https://publications.waset.org/abstracts/131031/maturity-model-for-agro-industrial-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131031.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">137</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> Assessment of Artists’ Socioeconomic and Working Conditions: The Empirical Case of Lithuania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rusne%20Kregzdaite">Rusne Kregzdaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Godlevska"> Erika Godlevska</a>, <a href="https://publications.waset.org/abstracts/search?q=Morta%20Vidunaite"> Morta Vidunaite</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main aim of this research is to explore existing methodologies for artists’ labour force and create artists’ socio-economic and creative conditions in an assessment model. Artists have dual aims in their creative working process: 1) income and 2) artistic self-expression. The valuation of their conditions takes into consideration both sides: the factors related to income and the satisfaction of the creative process and its result. The problem addressed in the study: tangible and intangible artists' criteria used for assessments creativity conditions. The proposed model includes objective factors (working time, income, etc.) and subjective factors (salary covering essential needs, self-satisfaction). Other intangible indicators are taken into account: the impact on the common culture, social values, and the possibility to receive awards, to represent the country in the international market. The empirical model consists of 59 separate indicators, grouped into eight categories. The deviation of each indicator from the general evaluation allows for identifying the strongest and the weakest components of artists’ conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artist%20conditions" title="artist conditions">artist conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=artistic%20labour%20force" title=" artistic labour force"> artistic labour force</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20policy" title=" cultural policy"> cultural policy</a>, <a href="https://publications.waset.org/abstracts/search?q=indicator" title=" indicator"> indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment%20model" title=" assessment model"> assessment model</a> </p> <a href="https://publications.waset.org/abstracts/149554/assessment-of-artists-socioeconomic-and-working-conditions-the-empirical-case-of-lithuania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149554.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Analysis of the Extreme Hydrometeorological Events in the Theorical Hydraulic Potential and Streamflow Forecast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Patricia%20Ibarra-Zavaleta">Sara Patricia Ibarra-Zavaleta</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabindranarth%20Romero-Lopez"> Rabindranarth Romero-Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosario%20Langrave"> Rosario Langrave</a>, <a href="https://publications.waset.org/abstracts/search?q=Annie%20Poulin"> Annie Poulin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Corzo"> Gerald Corzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Glaus"> Mathias Glaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Vega-Azamar"> Ricardo Vega-Azamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Norma%20Angelica%20Oropeza"> Norma Angelica Oropeza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The progressive change in climatic conditions worldwide has increased frequency and severity of extreme hydrometeorological events (EHE). Mexico is an example; this has been affected by the presence of EHE leaving economic, social and environmental losses. The objective of this research was to apply a Canadian distributed hydrological model (DHM) to tropical conditions and to evaluate its capacity to predict flows in a basin in the central Gulf of Mexico. In addition, the DHM (once calibrated and validated) was used to calculate the theoretical hydraulic power and the performance to predict streamflow before the presence of an EHE. The results of the DHM show that the goodness of fit indicators between the observed and simulated flows in the calibration process (NSE=0.83, RSR=0.021 and BIAS=-4.3) and validation: temporal was assessed at two points: point one (NSE=0.78, RSR=0.113 and BIAS=0.054) and point two (NSE=0.825, RSR=0.103 and BIAS=0.063) are satisfactory. The DHM showed its applicability in tropical environments and its ability to characterize the rainfall-runoff relationship in the study area.

The determination of the PA requires the evaluation of the reliability of the measurement instruments, in order to sustain the continuity and relevance of Recreovía as a community intervention. Objective: Establish the inter-rater reliability of the App for the System for Observing Play and Recreation in Communities (iSOPARC®) in the Recreovía of Bucaramanga, Colombia. Methods: Five trained observers at two observation points on the 2.3 km of the Recreovía (14th Street and 32nd Street) used the App (iSOPARC®), between 08:00 a.m. and 12:00 m. in periods of 20 minutes during a regular Sunday. Reliability analysis was performed using the Intraclass Correlation Coefficient (ICC 2.1). Results: A total of 2682 users were observed (43.6 % women) in 7 observations. ICC showed a range between 0.96 and 0.99 for the PA level and ICC between 0.95 and 0.99 for age group for the two observation points. Conclusion: The reliability found for the iSOPARC® guarantees the consecutive measurement of the PA level at the Recreovía, which will allow measuring it is effectiveness in the medium and long term, as a community intervention strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=observation" title=" observation"> observation</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=recreation" title=" recreation"> recreation</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/87017/reliability-of-an-application-for-the-system-for-observing-play-and-recreation-in-communities-in-the-recreovia-of-bucaramanga-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87017.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">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Microstructural and Corrosion Analysis of a Ti-Nb-Ta Biocompatible Dental Implant Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roxana%20Maria%20Angelescu">Roxana Maria Angelescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Doina%20R%C4%83ducanu"> Doina Răducanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Lucia%20Angelescu"> Mariana Lucia Angelescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ion%20Cinc%C4%83"> Ion Cincă</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasile%20D%C4%83nu%C5%A3%20Cojocaru"> Vasile Dănuţ Cojocaru</a>, <a href="https://publications.waset.org/abstracts/search?q=Cosmin%20Cotru%C8%9B"> Cosmin Cotruț</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eerban%20Nicolae"> Şerban Nicolae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Titanium alloys are often used for biomedical applications as hard tissue replacements, such as: orthopedic implants, spinal fixation devices and dental implants. Their advantages are well known and demonstrated: excellent mechanical properties, biocompatibility and good corrosion resistance, but it is also known that the main disadvantage of the metallic materials is their tendency of corrosion in in-vivo environments. In 1987, titanium was found to be the only metallic biomaterial that osseointegrates. The aim of this study was to investigate the microstructure and the corrosion behavior of the Ti-20Nb-5Ta wt% alloy. In this case Nb stabilizes the β-Ti structure and Ta is a highly passivating metal. The as studied alloy was melt under argon protective atmosphere in a levitation induction melting furnace, type FIVE CELES - MP25, with a nominal power of 25 kW and a melting capacity of 30 cm3. The microstructure of the as studied alloy was analyzed by using the electronic microscope Tescan Vega II-XMU. The phase structure of the as studied alloy was determined, as well as the crystalline grain size (100-200µ). To determine the corrosion behavior of the as studied alloy, the technique used was the linear polarization, with the PARSTAT 4000 potentiostat, produced by Princeton Applied Research; potentiodynamic curves were obtained with the VeraStudio v.2.4.2 software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title="corrosion resistance">corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a> </p> <a href="https://publications.waset.org/abstracts/25962/microstructural-and-corrosion-analysis-of-a-ti-nb-ta-biocompatible-dental-implant-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25962.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">543</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> Internal Power Recovery in Cryogenic Cooling Plants Part I: Expander Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ambra%20Giovannelli">Ambra Giovannelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Maria%20Archilei"> Erika Maria Archilei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The amount of the electrical power required by refrigeration systems is relevant worldwide. It is evaluated in the order of 15% of the total electricity production taking refrigeration and air-conditioning into consideration. For this reason, in the last years several energy saving techniques have been proposed to reduce the power demand of such plants. The paper deals with the development of an innovative internal recovery system for cryogenic cooling plants. Such a system consists in a Compressor-Expander Group (CEG) designed on the basis of the automotive turbocharging technology. In particular, the paper is focused on the design of the expander, the critical component of the CEG system. Due to the low volumetric flow entering the expander and the high expansion ratio, a commercial turbocharger expander wheel was strongly modified. It was equipped with a transonic nozzle, designed to have a radially inflow full admission. To verify the performance of such a machine and suggest improvements, two different set of nozzles have been designed and modelled by means of the commercial Ansys-CFX software. steady-state 3D CFD simulations of the second-generation prototype are presented and compared with the initial ones. <p class="card-text"><strong>Keywords:</strong> <a
