However, despite the legislative improvements introduced for construction and demolition waste (CDW), construction waste recycling rate remains well below other European countries and also below the target set for 2020. This situation can be due to many difficulties. i.e.: The difficulty of onsite segregation or the estimation in advance of the total amount generated. Despite these difficulties, the proper management of CDW must be one of the main aspects to be considered by the construction companies. In this sense, some large national companies are implementing Integrated Management Systems (IMS) including not only quality and safety aspects, but also environment issues. However, although this fact is a reality for large construction companies still the vast majority of companies need to adopt this trend. In short, it is common to find in small and medium enterprises a decentralized management system: A single system of quality management, another for system safety management and a third one for environmental management system (EMS). In addition, the EMSs currently used address CDW superficially and are mainly focus on other environmental concerns such as carbon emissions. Therefore, this research determines and implements a specific best practice management system for CDW based on eight procedures in a Spanish Construction company. The main advantages and drawbacks of its implementation are highlighted. Results of this study show that establishing and implementing a CDW management system in building works, improve CDW quantification as the company obtains their own CDW generation ratio. This helps construction stakeholders when developing CDW Management Plans and also helps to achieve a higher adjustment of CDW management costs. Finally, integrating this CDW system with the EMS of the company favors the cohesion of the construction process organization at all stages, establishing responsibilities in the field of waste and providing a greater control over the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20and%20demolition%20waste" title="construction and demolition waste">construction and demolition waste</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20practices" title=" best practices"> best practices</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20minimization" title=" waste minimization"> waste minimization</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20management%20systems" title=" quality management systems"> quality management systems</a> </p> <a href="https://publications.waset.org/abstracts/25052/integrating-best-practices-for-construction-waste-in-quality-management-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25052.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">533</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">425</span> The Influence of Japanese Poetry in Spanish Piano Music: Benet Casablancas and Mercedes Zavala’s Haikus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabel%20%20P%C3%A9rez%20Dobarro">Isabel Pérez Dobarro </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the mid-twentieth century, Spanish composers started looking beyond the national folkloric tradition (adopted by Albéniz, Granados, and Falla) and Rodrigo’s neoclassicism, and searched for other sources of inspiration. Japanese Haikus fascinated Spanish musicians, who found in their brevity and imagination a new avenue to develop their creativity. The goal of this research is to study how two renowned Spanish authors, Benet Casablancas and Mercedes Zavala, incorporated Haikus into their piano works. Based on Bruhn’s methodology on text and instrumental music relations, and developing a score and text analysis complemented by interviews with both composers, this study has revealed three possible interactions between the Haikus and these composers’ piano writing: inspiration, transmedialization, and mimesis. Findings also include specific technical gestures to support each of these approaches. Commonalities between their pieces and those by other non-Spanish composers such as Jonathan Harvey, John Cage, and Michael Berkeley have also been explored. According to the author's knowledge, this is the first study on the Japanese influence in Spanish piano music. Thus, it opens a new path for understanding musical exchanges between both countries as well as contemporary piano tools that support the interaction between text and music. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haiku" title="Haiku">Haiku</a>, <a href="https://publications.waset.org/abstracts/search?q=Spanish%20piano%20music" title=" Spanish piano music"> Spanish piano music</a>, <a href="https://publications.waset.org/abstracts/search?q=Benet%20Casablancas" title=" Benet Casablancas"> Benet Casablancas</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Zavala" title=" Mercedes Zavala"> Mercedes Zavala</a> </p> <a href="https://publications.waset.org/abstracts/128209/the-influence-of-japanese-poetry-in-spanish-piano-music-benet-casablancas-and-mercedes-zavalas-haikus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128209.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">152</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">424</span> Diversity of Halophilic Archaea from Ezzemoul sabkha in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karima%20Kharroub">Karima Kharroub</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Gomri"> Mohamed Amine Gomri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Monteoliva-Sanchez"> Mercedes Monteoliva-Sanchez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sabkhas and chotts are examples of hypersaline environments inhabited by halophilic microorganisms. In the present study, a culture-dependent methodology was used to determine the archaeal diversity present within Ezzemoul sabkha located in the north-eastern of Algeria. It was assessed using different media with different substrates in attempt to initiate the growth of wide spectrum of halophiles. Several strains were isolated and subjected to a polyphasic taxonomic characterization. The isolates tested placed within the family Halobacteriaceae, a group of extremely halophilic, aerobic archaea that have a salinity tolerance of 3 to 4M and associated with six genera Halorubrum, Halobacterium, Haloterrigena, Haloferax, Halomicrobium and Haloarcula. Halorubrum species were found to be the dominant archaea community as indicated by the presence of different strains recovered from this sabkha. In the other hand, two new species within Halobacteriaceae family; Halorubrum ezzemolulense sp. nov. and Halomicrobium katesii sp. nov. were described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sabkha" title="sabkha">sabkha</a>, <a href="https://publications.waset.org/abstracts/search?q=archaea" title=" archaea"> archaea</a>, <a href="https://publications.waset.org/abstracts/search?q=halophilic" title=" halophilic"> halophilic</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersaline%20environments" title=" hypersaline environments"> hypersaline environments</a> </p> <a href="https://publications.waset.org/abstracts/34592/diversity-of-halophilic-archaea-from-ezzemoul-sabkha-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34592.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">314</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">423</span> Kinetic Study of Thermal Degradation of a Lignin Nanoparticle-Reinforced Phenolic Foam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20C.%20Dom%C3%ADnguez">Juan C.

Nowadays, there is an increasing interest in the use of compounds to avoid decays in post-harvest. Triazole fungicides are agrochemicals widely used in the agricultural industry due to their wide spectrum of actions, and in some case, they are used in citrus fruit post-harvest. Moreover, its use is not authorized in plum post-harvest, but in order to a future possible authorization, the evolutions of propiconazole and tebuconazole residues are studied after its post-harvest application in ‘Angeleno’ plum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maximum%20residue%20limit%20%28MRL%29" title="maximum residue limit (MRL)">maximum residue limit (MRL)</a>, <a href="https://publications.waset.org/abstracts/search?q=triazole%20fungicides" title=" triazole fungicides"> triazole fungicides</a>, <a href="https://publications.waset.org/abstracts/search?q=decay" title=" decay"> decay</a>, <a href="https://publications.waset.org/abstracts/search?q=Prunus%20salicina" title=" Prunus salicina"> Prunus salicina</a> </p> <a href="https://publications.waset.org/abstracts/46899/evolution-of-propiconazole-and-tebuconazole-residues-through-the-post-harvest-application-in-angeleno-plum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46899.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">316</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">420</span> Utilizing the Principal Component Analysis on Multispectral Aerial Imagery for Identification of Underlying Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Bosques-Perez">Marcos Bosques-Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Izquierdo"> Walter Izquierdo</a>, <a href="https://publications.waset.org/abstracts/search?q=Harold%20Martin"> Harold Martin</a>, <a href="https://publications.waset.org/abstracts/search?q=Liangdon%20Deng"> Liangdon Deng</a>, <a href="https://publications.waset.org/abstracts/search?q=Josue%20Rodriguez"> Josue Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Thony%20Yan"> Thony Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Cabrerizo"> Mercedes Cabrerizo</a>, <a href="https://publications.waset.org/abstracts/search?q=Armando%20Barreto"> Armando Barreto</a>, <a href="https://publications.waset.org/abstracts/search?q=Naphtali%20Rishe"> Naphtali Rishe</a>, <a href="https://publications.waset.org/abstracts/search?q=Malek%20Adjouadi"> Malek Adjouadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aerial imagery is a powerful tool when it comes to analyzing temporal changes in ecosystems and extracting valuable information from the observed scene. It allows us to identify and assess various elements such as objects, structures, textures, waterways, and shadows. To extract meaningful information, multispectral cameras capture data across different wavelength bands of the electromagnetic spectrum. In this study, the collected multispectral aerial images were subjected to principal component analysis (PCA) to identify independent and uncorrelated components or features that extend beyond the visible spectrum captured in standard RGB images. The results demonstrate that these principal components contain unique characteristics specific to certain wavebands, enabling effective object identification and image segmentation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=multispectral" title=" multispectral"> multispectral</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a> </p> <a href="https://publications.waset.org/abstracts/170875/utilizing-the-principal-component-analysis-on-multispectral-aerial-imagery-for-identification-of-underlying-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170875.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">175</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">419</span> From Research to Practice: Upcycling Cinema Icons</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Rodriguez%20Sanchez">Mercedes Rodriguez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Luce%C3%B1o%20Casals"> Laura Luceño Casals</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rise of social media, creative people and brands everywhere are constantly generating content. The students with Bachelor's Degrees in Fashion Design use platforms such as Instagram or TikTok to look for inspiration and entertainment, as well as a way to develop their own ideas and share them with a wide audience. Information and Communications Technologies (ICT) have become a central aspect of higher education, virtually affecting every aspect of the student experience. Following the current trend, during the first semester of the second year, a collaborative project across two subjects –Design Management and History of Fashion Design– was implemented. After an introductory class focused on the relationship between fashion and cinema, as well as a brief history of 20th-century fashion, the students freely chose a work team and an iconic look from a movie costume. They researched the selected movie and its sociocultural context, analyzed the costume and the work of the designer, and studied the style, fashion magazines and most popular films of the time. Students then redesigned and recreated the costume, for which they were compelled to recycle the materials they had available at home as an unavoidable requirement of the activity. Once completed the garment, students delivered in-class, team-based presentations supported by the final design, a project summary poster and a making-of video, which served as a documentation tool of the costume design process. The methodologies used include Challenge-Based Learning (CBL), debates, Internet research, application of Information and Communications Technologies, and viewing clips of classic films, among others. After finishing the projects, students were asked to complete two electronic surveys to measure the acquisition of transversal and specific competencies of each subject. Results reveal that this activity helped the students' knowledge acquisition, a deeper understanding of both subjects and their skills development. The classroom dynamic changed. The multidisciplinary approach encouraged students to collaborate with their peers, while educators were better able to keep students' interest and promote an engaging learning process. As a result, the activity discussed in this paper confirmed the research hypothesis: it is positive to propose innovative teaching projects that combine academic research with playful learning environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinema" title="cinema">cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperative%20learning" title=" cooperative learning"> cooperative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion%20design" title=" fashion design"> fashion design</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=upcycling" title=" upcycling"> upcycling</a> </p> <a href="https://publications.waset.org/abstracts/160029/from-research-to-practice-upcycling-cinema-icons" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">418</span> Attitude towards Doping of High-Performance Athletes in a Sports Institute of the City of Medellin, Colombia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuban%20Sebastian%20Cuartas-Agudelo">Yuban Sebastian Cuartas-Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Marcela%20L%C3%B3pez-Hincapi%C3%A9"> Sandra Marcela López-Hincapié</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivianna%20Alexandra%20Garrido-Altamar"> Vivianna Alexandra Garrido-Altamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez-G%C3%A1zquez"> María de los Ángeles Rodríguez-Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mej%C3%ADa"> Camilo Ruiz-Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez-S%C3%A1nchez"> Lina María Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez-Dom%C3%ADnguez"> Gloria Inés Martínez-Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Eduardo%20Contreras"> Luis Eduardo Contreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Eduardo%20Marino-Isaza"> Felipe Eduardo Marino-Isaza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Doping is a prohibited practice in competitive sports with potential adverse effects; therefore, it is crucial to describe the attitudes of athletes towards this behavior and to determine which o these increase the susceptibility to carry out this practice. Objective: To determine the attitude of high-performance athletes towards doping in a sports institute in the city of Medellin, Colombia. Methods: We performed a cross-sectional study during 2016, with a sample taken to convenience consisting of athletes over 18 years old enrolled in a sports institute of the city of Medellin (Colombia). The athletes filled by themselves the Petroczi and Aidman questionnaire: Performance Enhancement Attitude Scale (PEAS) adapted to the Spanish language by Morente-Sánchez et al. This scale has 17 items with likert answer options, with a score ranging from 1 to 6, with a higher score indicating a stronger tendency towards doping practices. Results: 112 athletes were included with an average age of 21.6 years old, a 60% of them were male and the most frequent sports were karate 17%, judo 12.5% and athletics 9.8%. The average score of the questionnaire was 35.5 points of a 102 possible points. The lowest score was obtained in the following items: Is Doping necessary 1,4 and Doping isn’t cheating, everyone does it 1,5.

The main objective of this paper is to evaluate the potential of the agro-industrial banana crop residues in the production of bioethanol. A factorial design of 2<sup>4</sup> was used, the design has variables such as pH, time and concentration of hydrolysis, another variable is the time of fermentation that is of 7 or 15 days. In the hydrolysis phase, the pH is acidic (H<sub>2</sub>SO<sub>4</sub>) or basic (NaOH), the time is 30 or 15 minutes and the concentration is 0.1 or 0.5 M. It was observed that basic media, low concentrations, fermentation, and higher pretreatment times produced better performance in terms of biofuel obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioethanol" title="bioethanol">bioethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuels" title=" biofuels"> biofuels</a>, <a href="https://publications.waset.org/abstracts/search?q=banana%20waste" title=" banana waste"> banana waste</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrolysis" title=" hydrolysis"> hydrolysis</a> </p> <a href="https://publications.waset.org/abstracts/54596/production-of-bioethanol-through-hydrolysis-of-agro-industrial-banana-crop-residues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54596.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">427</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">416</span> Antimicrobial Activity of Biosynthesized Silver Nanoparticles with Handroanthus Chrysanthus Flower Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Padilla">Eduardo Padilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Daniel%20Rodriguez"> Luis Daniel Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Sanchez"> Ivan Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelica%20Sofia%20Go"> Angelica Sofia Go</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The synthesis and application of metallic nanoparticles have increased in recent years. Biological methods go beyond the chemical and physical synthesis that is expensive and not friendly to the environment. Therefore, in this study, silver nanoparticles were synthesized biologically in an environmentally friendly way by Handroanthus chrysanthus flower aqueous extract (AgNPs) that contains phytochemicals capable of reducing silver nitrate. AgNPs were characterized visually by UV-visible spectroscopy and TEM. The antimicrobial activity of the AgNPs was tested by determining the minimum inhibitory concentration (MIC), and minimal bactericidal concentration (MBC) in Escherichia coli and Staphylococcus aureus strains AgNPs showed potent antimicrobial activity against gram-negative and gram-positive bacteria. MIC and MBC values were as low as 41.6, and 83.2 ug/mL using AgNPs biosynthesized by H. chrysanthus flower extract. This nanoparticle could be the basis for the formulation of disinfectants for use in the food and pharmaceutical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=flower%20extract" title=" flower extract"> flower extract</a>, <a href="https://publications.waset.org/abstracts/search?q=Handroanthus" title=" Handroanthus"> Handroanthus</a> </p> <a href="https://publications.waset.org/abstracts/161062/antimicrobial-activity-of-biosynthesized-silver-nanoparticles-with-handroanthus-chrysanthus-flower-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161062.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">112</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">415</span> Development of Mg-Containing Hydroxyapatite-Based Bioceramics From Phosphate Rock for Bone Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Mercedes%20Barroso%20Pinz%C3%B3n">Sara Mercedes Barroso Pinzón</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81lvaro%20Jes%C3%BAs%20Caicedo%20Castro"> Álvaro Jesús Caicedo Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Javer%20S%C3%A1nchez%20Herencia"> Antonio Javer Sánchez Herencia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years there has been increased academic and industrial research into the development of orthopaedic implants with structural properties and functionality similar to mechanical strength, osseointegration, thermal stability and antibacterial capacity similar to bone structure.

The HEA field has promoted the exploration of several compositions including the addition of non-metallic elements like carbon, which in traditional metallurgy is mainly used in the steel industry. The aim of this work was the synthesis of equiatomic FeCrNiMnTi high entropy alloys, with minor carbon content, by mechanical alloying and sintering. The effect of the addition of carbon nanotubes and graphite were evaluated by X-ray diffraction, scanning electron microscopy, and microhardness test. The structural and microstructural characteristics of the equiatomic alloys, as well as their hardness were compared with those of an austenitic AISI 321 stainless steel processed under the same conditions. The results showed that porosity in bulk samples decreases with carbon nanotubes addition, while the equiatomic composition favors the formation of titanium carbide and increased the AISI 321 hardness more than three times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite" title=" graphite"> graphite</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20entropy%20alloys" title=" high entropy alloys"> high entropy alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20alloying" title=" mechanical alloying"> mechanical alloying</a> </p> <a href="https://publications.waset.org/abstracts/87464/effect-of-carbon-additions-on-fecrnimnti-high-entropy-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87464.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">198</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">413</span> Obtaining Bioactive Mg-hydroxyapatite Composite Ceramics From Phosphate Rock For Medical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Mercedes%20Barroso%20Pinz%C3%B3n">Sara Mercedes Barroso Pinzón</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Javier%20Sanch%C3%A9z%20Herencia"> Antonio Javier Sanchéz Herencia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bego%C3%B1a%20Ferrari"> Begoña Ferrari</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81lvaro%20Jes%C3%BAs%20Castro"> Álvaro Jesús Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current need for durable implants and bone substitutes characterised by biocompatibility, bioactivity and mechanical properties, without immunological rejection, is a major challenge for scientists.

Physical and chemical characterization of recycled aggregates showed continues particle size distribution curve, lower density and higher absorption, which was the reason to use additive to obtain required mortar consistency. Main crystalline phases determined in the X-Ray diffraction test were calcite, quartz, and gypsum. Performed tests show that cement-based mortars fabricated with CEM IV/B (V) 32. 5 N can incorporate recycled aggregates coming from ceramic, concrete and mixed recycling processes, using 1:3 and 1:4 cement-to-aggregate proportions, complying with the limits established by the Spanish standards. It was concluded that recycled mortar coming from concrete recycling process is the one which presents better characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20and%20demolition%20waste" title="construction and demolition waste">construction and demolition waste</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20mortar" title=" masonry mortar"> masonry mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20aggregate" title=" recycled aggregate"> recycled aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20treatment" title=" waste treatment"> waste treatment</a> </p> <a href="https://publications.waset.org/abstracts/52696/comparative-analysis-of-three-types-of-recycled-aggregates-and-its-use-in-masonry-mortar-fabrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52696.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">423</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">411</span> Thermal Behavior of a Ventilated Façade Using Perforated Ceramic Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helena%20L%C3%B3pez-Moreno">Helena López-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoni%20Rodr%C3%ADguez-S%C3%A1nchez"> Antoni Rodríguez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmen%20Vi%C3%B1as-Arrebola"> Carmen Viñas-Arrebola</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Porras-Amores"> Cesar Porras-Amores</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ventilated façade has great advantages when compared to traditional façades as it reduces the air conditioning thermal loads due to the stack effect induced by solar radiation in the air chamber. Optimizing energy consumption by using a ventilated façade can be used not only in newly built buildings but also it can be implemented in existing buildings, opening the field of implementation to energy building retrofitting works. In this sense, the following three prototypes of façade where designed, built and further analyzed in this research: non-ventilated façade (NVF); slightly ventilated façade (SLVF) and strongly ventilated façade (STVF). The construction characteristics of the three facades are based on the Spanish regulation of building construction “Technical Building Code”. The façades have been monitored by type-k thermocouples in a representative day of the summer season in Madrid (Spain). Moreover, an analysis of variance (ANOVA) with repeated measures, studying the thermal lag in the ventilated and no-ventilated façades has been designed. Results show that STVF façade presents higher levels of thermal inertia as the thermal lag reduces up to 100% (daily mean) compared to the non-ventilated façade. In addition, the statistical analysis proves that an increase of the ventilation holes size in STVF façades does not improve the thermal lag significantly (p > 0.05) when compared to the SLVF façade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ventilated%20fa%C3%A7ade" title="ventilated façade">ventilated façade</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20behavior" title=" thermal behavior"> thermal behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/25054/thermal-behavior-of-a-ventilated-facade-using-perforated-ceramic-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25054.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">491</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">410</span> DNA-Based Analysis of Gut Content of Zygoribatula sp (Acari: Oribatida) and Scheloribates sp (Acari: Oribatida), under the Canopy of Prosopis Laevigata, in a Semiarid Land</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Isaac%20Sanchez%20Chavez">Daniel Isaac Sanchez Chavez</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvador%20Rodr%C3%ADguez%20Zaragoza"> Salvador Rodríguez Zaragoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Velez%20Aguilar"> Patricia Velez Aguilar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In arid and semi-arid regions, plants are essential in the functional activity and productivity, modifying the microclimatic conditions of their environment, which allows many organisms to grow under them. Within these organisms, oribatid mites play a key role in reintegrating nutrients into the soil through the consumption of soil fungi. However, oribatid mites feed on a vast array of fungal species, which is likely to have strong impacts on their population dynamics and their environment. So, in this study, the aim was to determine the gut content of the abundant oribatid mites Zygoribatula sp and Scheloribates sp, under the canopy of the bush P. laevigata in a semi-arid zone through DNA-based analysis. The results showed the presence in the gut of both mites of different fungal taxa. Fungi, such as Aspergillus sp and Mortierella sp, probably served as a food despite the production of deterrent compounds or structures from both fungal species. Saccharomyces sp might serve as well as a food source; however, it might be part of their microbial endosymbionts. On the other hand, the presence of Beauveria sp indicates a probable pathogenicity interaction, instead of fungal consumption, since this fungus is known to be entomopathogenic. Finally, the results might indicate a feeding preference to certain soil fungi according to diverse features from both taxa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microenvironment" title="microenvironment">microenvironment</a>, <a href="https://publications.waset.org/abstracts/search?q=endosymbionts" title=" endosymbionts"> endosymbionts</a>, <a href="https://publications.waset.org/abstracts/search?q=Oribatida" title=" Oribatida"> Oribatida</a>, <a href="https://publications.waset.org/abstracts/search?q=fungi" title=" fungi"> fungi</a> </p> <a href="https://publications.waset.org/abstracts/122128/dna-based-analysis-of-gut-content-of-zygoribatula-sp-acari-oribatida-and-scheloribates-sp-acari-oribatida-under-the-canopy-of-prosopis-laevigata-in-a-semiarid-land" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122128.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">142</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">409</span> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals.

Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">576</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">408</span> An Experimental Study of the External Thermal Insulation System’s (ETICS) Efficiency in Buildings during Spring Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carmen%20Vi%C3%B1as%20Arrebola">Carmen Viñas Arrebola</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Rodriguez%20Sanchez"> Antonio Rodriguez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheila%20Varela%20Lujan"> Sheila Varela Lujan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariano%20Gonzalez%20Cortina"> Mariano Gonzalez Cortina</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Porras%20Amores"> Cesar Porras Amores</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research group TEMA from the School of Building (UPM) is working in the line of energy efficiency and comfort in building. The need to reduce energy consumption in the building construction implies designing new constructive systems. These systems help to reduce both consumption and energy losses in order to achieve adequate thermal comfort for people in any type of building. In existing buildings the best option is the rehabilitation focused on thermal insulation. The aim of this paper is to design, monitor and analyze the first results of thermal behavior of the ETICS system in façades. This retrofitting solution consists of adding thermal insulation on the outside of the building, helping to create a continuous envelope on the façades. The analysis is done by comparing a rehabilitated part of the building with ETICS system and another part which has not been rehabilitated, and it is taken as reference. Both of them have the same characteristics. Temperature measurements were taken with type K thermocouples according to the previous design of the monitoring and in the same period of time. The pilot building of the study is situated in Benimamet Street, in San Cristobal de Los Ángeles, in the south of Madrid. It was built in the late 50s. The 51st entrance hall, which is restored, and the 47th entrance hall, in original conditions, have been studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comfort%20in%20building" title="comfort in building">comfort in building</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency%20in%20building" title=" energy efficiency in building"> energy efficiency in building</a>, <a href="https://publications.waset.org/abstracts/search?q=ETICS" title=" ETICS"> ETICS</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a> </p> <a href="https://publications.waset.org/abstracts/52705/an-experimental-study-of-the-external-thermal-insulation-systems-etics-efficiency-in-buildings-during-spring-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52705.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">315</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">407</span> Chitin Crystalline Phase Transition Promoted by Deep Eutectic Solvent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diana%20G.%20Ramirez-Wong">Diana G.

A careful analysis of the chemical and crystalline structure was followed along the synthesis of the films, revealing crystalline-phase transitions. The full conversion of alpha- to beta-, or alpha- to gamma-chitin structure were detected by XRD and NMR on the films. The synthesis of highly crystalline monophasic gamma-chitin films was achieved using a DES; whereas HFIP helps to promote the beta-phase.

Poultry manure (PM), municipal organic wastes (MOW) and sugar beet lime sludge (LS) are produced in large quantities in Morocco. The co-composting of these organic wastes was investigated. The recycling and the valorization of such wastes is environmentally and economically beneficial especially for PM which is known source of bacterial pathogens. The aerobic biodegradation process was carried out by using three windrows of variable compositions: C1 prepared without LS (only MOW were composted with PM), C2 prepared from MOW plus PM and10% LS; and the last one C3 from MOW plus PM and 20% LS. The main process physico-chemical parameters (temperature, pH, humidity and C/N) and microbiological populations (mesophilic and thermophilic flora, total coliform, fecal coliform, Streptococci, Staphylococcus aureus and mesophilic fungi) were monitored over three months to ascertain the compost maturity and to ensure the compost hygienic aspect. The final products were characterized by their relatively high organic matter content, and low C/N ratio of 10.6-10.9. The organic matter degradation was reached approximately 59% for C2 and C3. In addition, the monitoring of the microbial population showed that the produced composts are mature and hygienic. The agronomic valorization of the final composts was tested on radish plant with tree level of composts and poultry manure without composting. The primary results of field trial showed a growth of radish plant biomass and root development without any phytotoxicity detected which reflects the quality of the composts produced. As for poultry manure it allowed to have a better results than other composts because of its readily available nitrogen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compost" title="compost">compost</a>, <a href="https://publications.waset.org/abstracts/search?q=municipal%20organic%20wastes" title=" municipal organic wastes"> municipal organic wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20manure" title=" poultry manure"> poultry manure</a>, <a href="https://publications.waset.org/abstracts/search?q=radish%20crop" title=" radish crop"> radish crop</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20beet%20lime%20sludge" title=" sugar beet lime sludge"> sugar beet lime sludge</a> </p> <a href="https://publications.waset.org/abstracts/42134/m-j-rodriguez-f-m-sanchez-b-velardo-p-calvo-m-j-serradilla-j-delgado-j-m-lopez" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42134.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">312</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">405</span> Moving towards a General Definition of Public Happiness: A Grounded Theory Approach to the Recent Academic Research on Well-Being</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Sanchez-Sanchez">Cristina Sanchez-Sanchez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although there seems to be a growing interest in the study of the citizen’s happiness as an alternative measure of a country’s progress to GDP, happiness as a public concern is still an ambiguous concept, hard to define. Moreover, different notions are used indiscriminately to talk about the same thing. This investigation aims to determine the conceptions of happiness, well-being and quality of life that originate from the indexes that different governments and public institutions around the world have created to study them. Through the Scoping Review method, this study identifies the recent academic research in this field (a total of 267 documents between 2006 and 2016) from some of the most popular social sciences databases around the world, Web of Science, Scopus, JSTOR, Sage, EBSCO, IBSS and Google Scholar, and in Spain, ISOC and Dialnet. These 267 documents referenced 53 different indexes and researches.

Objective: To establish the main clinical and epidemiological characteristics of patients who present with chest pain to the emergency department in a private clinic from the city of Medellin, during 2014-2015. Methods: Cross-sectional retrospective observational study. Population and sample were patients who consulted for chest pain in the emergency department who met the eligibility criteria. The information was analyzed in SPSS program vr.21; qualitative variables were described through relative frequencies, and the quantitative through mean and standard deviation ‬or medians according to their distribution in the study population. Results: A total of 231 patients were evaluated, the mean age was 49.5 ± 19.9 years, 56.7% were females. The most frequent pathological antecedents were hypertension 35.5%, diabetes 10,8%, dyslipidemia 10.4% and coronary disease 5.2%. Regarding pain features, in 40.3% of the patients the pain began abruptly, in 38.2% it had a precordial location, for 20% of the cases physical activity acted as a trigger, and 60.6% was oppressive. Costochondritis was the most common cause of chest pain among patients with an established etiologic diagnosis, representing the 18.2%. Conclusions: Although the clinical features of pain reported coincide with the clinical presentation of an acute coronary syndrome, the most common cause of chest pain in study population was costochondritis instead, indicating that it is a differential diagnostic in the approach of patients with pain acute chest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20coronary%20syndrome" title="acute coronary syndrome">acute coronary syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20pain" title=" chest pain"> chest pain</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=osteochondritis" title=" osteochondritis"> osteochondritis</a> </p> <a href="https://publications.waset.org/abstracts/71857/characterization-of-chest-pain-in-patients-consulting-to-the-emergency-department-of-a-health-institution-high-level-of-complexity-during-2014-2015-medellin-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71857.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">343</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">403</span> Clinical and Epidemiological Profile of Patients with Chronic Obstructive Pulmonary Disease in a Medical Institution from the City of Medellin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andres%20Agudelo-Velez">Camilo Andres Agudelo-Velez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Martinez-Sanchez"> Lina María Martinez-Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla-Hernandez"> Natalia Perilla-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20De%20Los%20Angeles%20Rodriguez-Gazquez"> Maria De Los Angeles Rodriguez-Gazquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hernandez-Restrepo"> Felipe Hernandez-Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Andrea%20Quintero-Moreno"> Dayana Andrea Quintero-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mejia"> Camilo Ruiz-Mejia</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz-Trujillo"> Isabel Cristina Ortiz-Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Maria%20Zuluaga-Quintero"> Monica Maria Zuluaga-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chronic obstructive pulmonary disease is common condition, characterized by a persistent blockage of airflow, partially reversible and progressive, that represents 5% of total deaths around the world, and it is expected to become the third leading cause of death by 2030.

To bridge the distance learning gap, our project introduces an innovative initiative focused on teaching high school students basic biotechnology techniques. We aim to empower young minds and foster curiosity by encouraging students to create their own DIY biotechnology laboratories using easily accessible materials found at home. This abstract outlines the key aspects of our project, highlighting its importance, methodology, and evaluation approach.In response to the pandemic's limitations, our project targets the delivery of biotechnology education at a distance. By engaging students in hands-on experiments, we seek to provide an enriching learning experience despite the constraints of remote learning. The DIY approach allows students to explore scientific concepts in a practical and enjoyable manner, nurturing their interest in biotechnology and molecular biology. Originally designed to assess professional-level research programs, we have adapted the URSSA to suit the context of biotechnology and molecular biology synthesis for high school students. By applying this tool before and after the experimental sessions, we aim to gauge the program's impact on students' learning experiences and skill development. Our project's significance lies not only in its novel approach to teaching biotechnology but also in its adaptability to the current global crisis. By providing students with a stimulating and interactive learning environment, we hope to inspire educators and institutions to embrace creative solutions during challenging times. Moreover, the insights gained from our evaluation will inform future efforts to enhance distance learning programs and promote accessible science education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DIY%20biotechnology" title="DIY biotechnology">DIY biotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20school%20students" title=" high school students"> high school students</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20learning" title=" distance learning"> distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic%20education" title=" pandemic education"> pandemic education</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20research%20student%20self-assessment%20%28URSSA%29" title=" undergraduate research student self-assessment (URSSA)"> undergraduate research student self-assessment (URSSA)</a> </p> <a href="https://publications.waset.org/abstracts/170949/empowering-minds-and-unleashing-curiosity-diy-biotechnology-for-high-school-students-in-the-age-of-distance-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170949.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">401</span> Clinical and Epidemiological Profile in Patients with Preeclampsia in a Private Institution in Medellin, Colombia 2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez">Camilo Andrés Agudelo Vélez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo"> Isabel Cristina Ortiz Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Evert%20Armando%20Jim%C3%A9nez%20Cotes"> Evert Armando Jiménez Cotes</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Duque%20Restrepo"> Daniel Duque Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hern%C3%A1ndez%20Restrepo"> Felipe Hernández Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Andrea%20Quintero%20Moreno"> Dayana Andrea Quintero Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jos%C3%A9%20Builes%20G%C3%B3mez"> Juan José Builes Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz%20Mej%C3%ADa"> Camilo Ruiz Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lucia%20Arango%20G%C3%B3mez"> Ana Lucia Arango Gómez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Preeclampsia is a clinical complication during pregnancy with high incidence in Colombia; therefore, it is important to evaluate the influence of external conditions and medical interventions, in order to promote measures that encourage improvements in the quality of life. Objective: Determine clinical and sociodemographic variables in women with preeclampsia. Methods: This cross-sectional study enrolled 50 patients with the diagnosis of preeclampsia, from a private institution in Medellin, during 2015. We used the software SPSS ver.20 for statistical analysis. For the qualitative variables, we calculated the mean and standard deviation, while, for ordinal and nominal levels of quantitative variables, ratios were estimated. Results: The average age was 26.8±5.9 years. The predominant characteristics were socioeconomic stratum 2 (48%), students (55%), mixed race (46%) and middle school as level of education (38%). As for clinical features, 72% of the cases were mild preeclampsia, and 22% were severe forms. The most common clinical manifestations were edema (46%), headache (62%), and proteinuria (55%). As for the Gyneco-obstetric history, 8% reported previous episodes of this disease and it was the first pregnancy for 60% of the patients. Conclusions: Preeclampsia is a frequent condition in young women; on the other hand, headache and edema were the most common reasons for consultation, therefore, doctors need to be aware of these symptoms in pregnant women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-eclampsia" title="pre-eclampsia">pre-eclampsia</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertension" title=" hypertension"> hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy%20complications" title=" pregnancy complications"> pregnancy complications</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal" title=" abdominal"> abdominal</a>, <a href="https://publications.waset.org/abstracts/search?q=edema" title=" edema"> edema</a> </p> <a href="https://publications.waset.org/abstracts/46372/clinical-and-epidemiological-profile-in-patients-with-preeclampsia-in-a-private-institution-in-medellin-colombia-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46372.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">362</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">400</span> Influence of Processing Parameters in Selective Laser Melting on the Microstructure and Mechanical Properties of Ti/Tin Composites With in-situ and ex-situ Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20S%C3%A1nchez%20de%20Rojas%20Candela">C.

Rams</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selective laser melting is one of the most commonly used AM techniques. In it, a thin layer of metallic powder is deposited, and a laser is used to melt selected zones. The accumulation of layers, each one molten in the preselected zones, gives rise to the formation of a 3D sample with a nearly arbitrary design. To ensure that the properties of the final parts match those of the powder, all the process is carried out in an inert atmosphere, preferentially Ar, although this gas could be substituted. Ti6Al4V alloy is widely used in multiple industrial applications such as aerospace, maritime transport and biomedical, due to its properties. However, due to the demanding requirements of these applications, greater hardness and wear resistance are necessary, together with a better machining capacity, which currently limits its commercialization. To improve these properties, in this study, Selective Laser Melting (SLM) is used to manufacture Ti/TiN metal matrix composites with in-situ and ex-situ titanium nitride reinforcement where the scanning speed is modified (from 28.5 up to 65 mm/s) to study the influence of the processing parameters in SLM. A one-step method of nitriding the Ti6Al4V alloy is carried out to create in-situ TiN reinforcement in a reactive atmosphere and it is compared with ex-situ composites manufactured by previous mixture of both the titanium alloy powder and the ceramic reinforcement particles. The microstructure and mechanical properties of the different Ti/TiN composite materials have been analyzed. As a result, the existence of a similar matrix has been confirmed in in-situ and ex-situ fabrications and the growth mechanisms of the nitrides have been studied. An increase in the mechanical properties with respect to the initial alloy has been observed in both cases and related to changes in their microstructure. Specifically, a greater improvement (around 30.65%) has been identified in those manufactured by the in-situ method at low speeds although other properties such as porosity must be improved for their future industrial applicability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=in-situ%20reinforcement" title="in-situ reinforcement">in-situ reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=nitriding%20reaction" title=" nitriding reaction"> nitriding reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20nitride" title=" titanium nitride"> titanium nitride</a> </p> <a href="https://publications.waset.org/abstracts/150850/influence-of-processing-parameters-in-selective-laser-melting-on-the-microstructure-and-mechanical-properties-of-titin-composites-with-in-situ-and-ex-situ-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150850.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">79</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">399</span> Use of Alternative and Complementary Therapies in Patients with Chronic Pain in a Medical Institution in Medellin, Colombia, 2014</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez">Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Molina%20Valencia"> Juliana Molina Valencia</a>, <a href="https://publications.waset.org/abstracts/search?q=Esteban%20Vallejo%20Agudelo"> Esteban Vallejo Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gallego%20Gonz%C3%A1lez"> Daniel Gallego González</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Isabel%20P%C3%A9rez%20Palacio"> María Isabel Pérez Palacio</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Ricardo%20Gaviria%20Garc%C3%ADa"> Juan Ricardo Gaviria García</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20De%20Los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María De Los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez"> Gloria Inés Martínez Domínguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alternative and complementary therapies constitute a vast and complex combination of interventions, philosophies, approaches, and therapies that acquire a holistic healthcare point of view, becoming an alternative for the treatment of patients with chronic pain. Objective: determine the characteristics of the use of alternative and complementary therapies in patients with chronic pain who consulted in a medical institution. Methodology: cross-sectional and descriptive study, with a population of patients that assisted to the outpatient consultation and met the eligibility criteria. Sampling was not conducted. A form was used for the collection of demographic and clinical variables and the Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) was validated. The analysis and processing of information was carried out using the SPSS program vr.19. Results: 220 people with chronic pain were included. The average age was 54.7±16.2 years, 78.2% were women, and 75.5% belonged to the socioeconomic strata 1 to 3. Musculoskeletal pain (77.7%), migraine (15%) and neuralgia (9.1%) were the most frequently types of chronic pain. 33.6% of participants have used some kind of alternative and complementary therapy; the most frequent were: homeopathy (14.5%), phytotherapy (12.7%), and acupuncture (11.4%). The total average HCAMQ score for the study group was 30.2±7.0 points, which shows a moderate attitude toward the use of complementary and alternative medicine. The highest scores according to the type of pain were: neuralgia (32.4±5.8), musculoskeletal pain (30.5±6.7), fibromyalgia (29.6±7.3) and migraine (28.5±8.8). The reliability of the HCAMQ was acceptable (Cronbach's α: 0.6). Conclusion: it was noted that the types of chronic pain and the clinical or therapeutic management of patients correspond to the data available in current literature. Despite the moderate attitude toward the use of these alternative and complementary therapies, one of every three patients uses them. <p class="card-text"><strong>Keywords:</strong> <a
