availability to deploy mobile applications for healthcare is increasing daily thru different mobile app stores. But within these capabilities the number of hacking attacks has also increased, in particular into medical mobile applications. The security vulnerabilities in medical mobile apps can be triggered by errors in code, incorrect logic, poor design, among other parameters. This is usually used by malicious attackers to steal or modify the users’ information. The aim of this research is to analyze the vulnerabilities detected in mobile medical apps according to risk factor standards defined by OWASP in 2014. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mHealth%20apps" title="mHealth apps">mHealth apps</a>, <a href="https://publications.waset.org/abstracts/search?q=OWASP" title=" OWASP"> OWASP</a>, <a href="https://publications.waset.org/abstracts/search?q=protocols" title=" protocols"> protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20vulnerabilities" title=" security vulnerabilities"> security vulnerabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a> </p> <a href="https://publications.waset.org/abstracts/38169/analysis-of-security-vulnerabilities-for-mobile-health-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38169.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">517</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">59</span> CSPG4 Molecular Target in Canine Melanoma, Osteosarcoma and Mammary Tumors for Novel Therapeutic Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Modesto">Paola Modesto</a>, <a href="https://publications.waset.org/abstracts/search?q=Floriana%20Fruscione"> Floriana Fruscione</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Martini"> Isabella Martini</a>, <a href="https://publications.waset.org/abstracts/search?q=Simona%20Perga"> Simona Perga</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Riccardo"> Federica Riccardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariateresa%20Camerino"> Mariateresa Camerino</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Giacobino"> Davide Giacobino</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Gola"> Cecilia Gola</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Licenziato"> Luca Licenziato</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabetta%20Razzuoli"> Elisabetta Razzuoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Katia%20Varello"> Katia Varello</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorella%20Maniscalco"> Lorella Maniscalco</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Bozzetta"> Elena Bozzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Ferrari"> Angelo Ferrari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Canine and human melanoma, osteosarcoma (OSA), and mammary carcinomas are aggressive tumors with common characteristics making dogs a good model for comparative oncology. Novel therapeutic strategies against these tumors could be useful to both species. In humans, chondroitin sulphate proteoglycan 4 (CSPG4) is a marker involved in tumor progression and could be a candidate target for immunotherapy. The anti-CSPG4 DNA electrovaccination has shown to be an effective approach for canine malignant melanoma (CMM) [1]. An immunohistochemistry evaluation of CSPG4 expression in tumour tissue is generally performed prior to electrovaccination. To assess the possibility to perform a rapid molecular evaluation and in order to validate these spontaneous canine tumors as the model for human studies, we investigate the CSPG4 gene expression by RT qPCR in CMM, OSA, and canine mammary tumors (CMT). The total RNA was extracted from RNAlater stored tissue samples (CMM n=16; OSA n=13; CMT n=6; five paired normal tissues for CMM, five paired normal tissues for OSA and one paired normal tissue for CMT), retro-transcribed and then analyzed by duplex RT-qPCR using two different TaqMan assays for the target gene CSPG4 and the internal reference gene (RG) Ribosomal Protein S19 (RPS19). RPS19 was selected from a panel of 9 candidate RGs, according to NormFinder analysis following the protocol already described [2]. Relative expression was analyzed by CFX Maestro™ Software. Student t-test and ANOVA were performed (significance set at P<0.05). Results showed that gene expression of CSPG4 in OSA tissues is significantly increased by 3-4 folds when compared to controls. In CMT, gene expression of the target was increased from 1.5 to 19.9 folds. In melanoma, although an increasing trend was observed, no significant differences between the two groups were highlighted. Immunohistochemistry analysis of the two cancer types showed that the expression of CSPG4 within CMM is concentrated in isles of cells compared to OSA, where the distribution of positive cells is homogeneous. This evidence could explain the differences in gene expression results.CSPG4 immunohistochemistry evaluation in mammary carcinoma is in progress. The evidence of CSPG4 expression in a different type of canine tumors opens the way to the possibility of extending the CSPG4 immunotherapy marker in CMM, OSA, and CMT and may have an impact to translate this strategy modality to human oncology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canine%20melanoma" title="canine melanoma">canine melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20mammary%20carcinomas" title=" canine mammary carcinomas"> canine mammary carcinomas</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20osteosarcoma" title=" canine osteosarcoma"> canine osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=CSPG4" title=" CSPG4"> CSPG4</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a> </p> <a href="https://publications.waset.org/abstracts/141925/cspg4-molecular-target-in-canine-melanoma-osteosarcoma-and-mammary-tumors-for-novel-therapeutic-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141925.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">174</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">58</span> Analysis of Differentially Expressed Genes in Spontaneously Occurring Canine Melanoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simona%20Perga">Simona Perga</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Beltramo"> Chiara Beltramo</a>, <a href="https://publications.waset.org/abstracts/search?q=Floriana%20Fruscione"> Floriana Fruscione</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Martini"> Isabella Martini</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Cavallo"> Federica Cavallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Riccardo"> Federica Riccardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Buracco"> Paolo Buracco</a>, <a href="https://publications.waset.org/abstracts/search?q=Selina%20Iussich"> Selina Iussich</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabetta%20Razzuoli"> Elisabetta Razzuoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Katia%20Varello"> Katia Varello</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorella%20Maniscalco"> Lorella Maniscalco</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Bozzetta"> Elena Bozzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Ferrari"> Angelo Ferrari</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Modesto"> Paola Modesto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Human and canine melanoma have common clinical, histologic characteristics making dogs a good model for comparative oncology. The identification of specific genes and a better understanding of the genetic landscape, signaling pathways, and tumor–microenvironmental interactions involved in the cancer onset and progression is essential for the development of therapeutic strategies against this tumor in both species. In the present study, the differential expression of genes in spontaneously occurring canine melanoma and in paired normal tissue was investigated by targeted RNAseq. Material and Methods: Total RNA was extracted from 17 canine malignant melanoma (CMM) samples and from five paired normal tissues stored in RNA-later. In order to capture the greater genetic variability, gene expression analysis was carried out using two panels (Qiagen): Human Immuno-Oncology (HIO) and Mouse-Immuno-Oncology (MIO) and the miSeq platform (Illumina). These kits allow the detection of the expression profile of 990 genes involved in the immune response against tumors in humans and mice. The data were analyzed through the CLCbio Genomics Workbench (Qiagen) software using the Canis lupus familiaris genome as a reference. Data analysis were carried out both comparing the biologic group (tumoral vs. healthy tissues) and comparing neoplastic tissue vs. paired healthy tissue; a Fold Change greater than two and a p-value less than 0.05 were set as the threshold to select interesting genes. Results and Discussion: Using HIO 63, down-regulated genes were detected; 13 of those were also down-regulated comparing neoplastic sample vs. paired healthy tissue. Eighteen genes were up-regulated, 14 of those were also down-regulated comparing neoplastic sample vs. paired healthy tissue. Using the MIO, 35 down regulated-genes were detected; only four of these were down-regulated, also comparing neoplastic sample vs. paired healthy tissue. Twelve genes were up-regulated in both types of analysis. Considering the two kits, the greatest variation in Fold Change was in up-regulated genes. Dogs displayed a greater genetic homology with humans than mice; moreover, the results have shown that the two kits are able to detect different genes. Most of these genes have specific cellular functions or belong to some enzymatic categories; some have already been described to be correlated to human melanoma and confirm the validity of the dog as a model for the study of molecular aspects of human melanoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20model" title="animal model">animal model</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20melanoma" title=" canine melanoma"> canine melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=spontaneous%20tumors" title=" spontaneous tumors"> spontaneous tumors</a>, <a href="https://publications.waset.org/abstracts/search?q=targeted%20RNAseq" title=" targeted RNAseq"> targeted RNAseq</a> </p> <a href="https://publications.waset.org/abstracts/141871/analysis-of-differentially-expressed-genes-in-spontaneously-occurring-canine-melanoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141871.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">199</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">57</span> Development and Control of Deep Seated Gravitational Slope Deformation: The Case of Colzate-Vertova Landslide, Bergamo, Northern Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Comella">Paola Comella</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincenzo%20Francani"> Vincenzo Francani</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Gattinoni"> Paola Gattinoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the Colzate-Vertova landslide, a Deep Seated Gravitational Slope Deformation (DSGSD) located in the Seriana Valley, Northern Italy. The paper aims at describing the development as well as evaluating the factors that influence the evolution of the landslide. After defining the conceptual model of the landslide, numerical simulations were developed using a finite element numerical model, first with a two-dimensional domain, and later with a three-dimensional one. The results of the 2-D model showed a displacement field typical of a sackung, as a consequence of the erosion along the Seriana Valley. The analysis also showed that the groundwater flow could locally affect the slope stability, bringing about a reduction in the safety factor, but without reaching failure conditions. The sensitivity analysis carried out on the strength parameters pointed out that slope failures could be reached only for relevant reduction of the geotechnical characteristics. Such a result does not fit the real conditions observed on site, where a number of small failures often develop all along the hillslope. The 3-D model gave a more comprehensive analysis of the evolution of the DSGSD, also considering the border effects. The results showed that the convex profile of the slope favors the development of displacements along the lateral valley, with a relevant reduction in the safety factor, justifying the existing landslides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20seated%20gravitational%20slope%20deformation" title="deep seated gravitational slope deformation">deep seated gravitational slope deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Italy" title=" Italy"> Italy</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide" title=" landslide"> landslide</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a> </p> <a href="https://publications.waset.org/abstracts/62818/development-and-control-of-deep-seated-gravitational-slope-deformation-the-case-of-colzate-vertova-landslide-bergamo-northern-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62818.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">365</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">56</span> Surgical Collaboration in Managing Spinal Cord Compression Due to a Pre-Vertebral Chordoma: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rose%20Virginy%20S.%20Bautista">Rose Virginy S.

The complexity of these tumors -given the rarity, location, and involvement of neurovascular structures- imposes a challenge in the diagnosis and management. We herein report a case of spinal cord compression due to a prevertebral cervical chordoma. The patient presented with a gradually enlarging lateral neck mass, with progressive bilateral extremity weakness and urinary incontinence; preoperative biopsy showed chordoma. A multidisciplinary approach for the management of this case was made, involving neurosurgery, head and neck surgery, and radiation oncology services. Surgical collaboration between the two cutting services was done to have a radical excision of the tumor and spinal cord decompression. The patient was then referred for adjuvant radiation therapy. With this collaborative treatment strategy, more comprehensive and quality care could be provided to our patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chordoma" title="chordoma">chordoma</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20collaboration" title=" surgical collaboration"> surgical collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20compression" title=" spinal cord compression"> spinal cord compression</a>, <a href="https://publications.waset.org/abstracts/search?q=neurosurgery" title=" neurosurgery"> neurosurgery</a>, <a href="https://publications.waset.org/abstracts/search?q=head%20and%20neck%20surgery" title=" head and neck surgery"> head and neck surgery</a> </p> <a href="https://publications.waset.org/abstracts/177775/surgical-collaboration-in-managing-spinal-cord-compression-due-to-a-pre-vertebral-chordoma-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177775.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">55</span> Social Impact Evaluation in the Housing Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edgard%20Barki">Edgard Barki</a>, <a href="https://publications.waset.org/abstracts/search?q=T%C3%A2nia%20Modesto%20Veludo-de-Oliveira"> Tânia Modesto Veludo-de-Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Zambaldi"> Felipe Zambaldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The social enterprise sector can be characterized as organizations that aim to solve social problems with financial sustainability and using market mechanisms. This sector has shown an increasing interest worldwide. Despite the growth and relevance of the sector, there is still a gap regarding the assessment of the social impact resulting from the initiatives of the organizations in this field. A number of metrics have been designed worldwide to evaluate the impact of social enterprises (e.g., IRIS, GIIRS, BACO), as well as some ad hoc studies that have been carried out, mainly in the microcredit sector, but there is still a gap to be filled in the development of research in social impact evaluation. Therefore, this research seeks to evaluate the social impact of two social enterprises (Terra Nova and Vivenda) in the area of housing in Brazil. To evaluate these impacts and their dimensions, we conducted an exploratory research, through three focus groups, thirty in-depth interviews and a survey with beneficiaries of both organizations. The results allowed us to evaluate how the two organizations were able to create a deep social impact in the populations served. Terra Nova has a more collective perspective, with a clear benefit of social inclusion and improvement of the community’s infrastructure, while Vivenda has a more individualized perspective, improving self-esteem, sociability and family coexistence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brazil" title="Brazil">Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=housing" title=" housing"> housing</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20enterprise" title=" social enterprise"> social enterprise</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20impact%20evaluation" title=" social impact evaluation"> social impact evaluation</a> </p> <a href="https://publications.waset.org/abstracts/64778/social-impact-evaluation-in-the-housing-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64778.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">443</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">54</span> Performance Assessment of Multi-Level Ensemble for Multi-Class Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodolfo%20Lorbieski">Rodolfo Lorbieski</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Modesto%20Nassar"> Silvia Modesto Nassar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many supervised machine learning tasks require decision making across numerous different classes. Multi-class classification has several applications, such as face recognition, text recognition and medical diagnostics. The objective of this article is to analyze an adapted method of Stacking in multi-class problems, which combines ensembles within the ensemble itself. For this purpose, a training similar to Stacking was used, but with three levels, where the final decision-maker (level 2) performs its training by combining outputs from the tree-based pair of meta-classifiers (level 1) from Bayesian families. These are in turn trained by pairs of base classifiers (level 0) of the same family. This strategy seeks to promote diversity among the ensembles forming the meta-classifier level 2. Three performance measures were used: (1) accuracy, (2) area under the ROC curve, and (3) time for three factors: (a) datasets, (b) experiments and (c) levels. To compare the factors, ANOVA three-way test was executed for each performance measure, considering 5 datasets by 25 experiments by 3 levels. A triple interaction between factors was observed only in time. The accuracy and area under the ROC curve presented similar results, showing a double interaction between level and experiment, as well as for the dataset factor. It was concluded that level 2 had an average performance above the other levels and that the proposed method is especially efficient for multi-class problems when compared to binary problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stacking" title="stacking">stacking</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-layers" title=" multi-layers"> multi-layers</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble" title=" ensemble"> ensemble</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-class" title=" multi-class"> multi-class</a> </p> <a href="https://publications.waset.org/abstracts/77466/performance-assessment-of-multi-level-ensemble-for-multi-class-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77466.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">269</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">53</span> Thermoluminescence Study of Cu Doped Lithium Tetra Borate Samples Synthesized by Water/Solution Assisted Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swarnapriya%20Thiyagarajan">Swarnapriya Thiyagarajan</a>, <a href="https://publications.waset.org/abstracts/search?q=Modesto%20Antonio%20Sosa%20Aquino"> Modesto Antonio Sosa Aquino</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Vallejo%20Hernandez"> Miguel Vallejo Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Senthilkumar%20Kalaiselvan%20Dhivyaraj"> Senthilkumar Kalaiselvan Dhivyaraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayaramakrishnan%20Velusamy"> Jayaramakrishnan Velusamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the lithium tetra borate (Li2B4O7) was prepared by used water/solution assisted synthesis method. Once finished the synthesization, Copper (Cu) were used to doping material with Li2B4O7 in order to enhance its thermo luminescent properties. The heating temperature parameters were 750°C for 2 hr and 150°C for 2hr. The samples produced by water assisted method were doped at different doping percentage (0.02%, 0.04%, 0.06%, 0.08%, 0.12%, 0.5%, 0.1%, and 1%) of Cu.The characteristics and identification of Li2B4O7 (undoped and doped) were determined in four tests. They are X-ray diffraction (XRD), Scanning electron microscope (SEM), Photoluminescence (PL), Ultra violet visible spectroscopy (UV Vis). As it is evidence from the XRD and SEM results the obtained Li2B4O7 and Li2B4O7 doping with Cu was confirmed and also confirmed the chemical compositition and their morphologies. The obtained lithium tetraborate XRD pattern result was verified with the reference data of lithium tetraborate with tetragonal structure from JCPDS. The glow curves of Li2B4O7 and Li2B4O7 : Cu were obtained by thermo luminescence (TLD) reader (Harshaw 3500). The pellets were irradiated with different kind of dose (58mGy, 100mGy, 500mGy, and 945mGy) by using an X-ray source. Finally this energy response was also compared with TLD100. The order of kinetics (b), frequency factor (S) and activation energy (E) or the trapping parameters were calculated using peak shape method. Especially Li2B4O7: Cu (0.1%) presents good glow curve in all kind of doses. The experimental results showed that this Li2B4O7: Cu could have good potential applications in radiation dosimetry. The main purpose of this paper is to determine the effect of synthesis on the TL properties of doped lithium tetra borate Li2B4O7. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dosimetry" title="dosimetry">dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiation" title=" irradiation"> irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20tetraborate" title=" lithium tetraborate"> lithium tetraborate</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoluminescence" title=" thermoluminescence"> thermoluminescence</a> </p> <a href="https://publications.waset.org/abstracts/69681/thermoluminescence-study-of-cu-doped-lithium-tetra-borate-samples-synthesized-by-watersolution-assisted-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69681.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">276</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">52</span> Employer Learning, Statistical Discrimination and University Prestige</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Bordon">Paola Bordon</a>, <a href="https://publications.waset.org/abstracts/search?q=Breno%20Braga"> Breno Braga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates whether firms use university prestige to statistically discriminate among college graduates. The test is based on the employer learning literature which suggests that if firms use a characteristic for statistical discrimination, this variable should become less important for earnings as a worker gains labor market experience. In this framework, we use a regression discontinuity design to estimate a 19% wage premium for recent graduates of two of the most selective universities in Chile. However, we find that this premium decreases by 3 percentage points per year of labor market experience. These results suggest that employers use college selectivity as a signal of workers' quality when they leave school. However, as workers reveal their productivity throughout their careers, they become rewarded based on their true quality rather than the prestige of their college. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employer%20learning" title="employer learning">employer learning</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20discrimination" title=" statistical discrimination"> statistical discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20returns" title=" college returns"> college returns</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20selectivity" title=" college selectivity"> college selectivity</a> </p> <a href="https://publications.waset.org/abstracts/19851/employer-learning-statistical-discrimination-and-university-prestige" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19851.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">580</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">51</span> The Impact of Health Tourism on Companies’ Performance: A Cross Country Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Paola%20Micheli">Anna Paola Micheli</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmelo%20Intrisano"> Carmelo Intrisano</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Maria%20Calce"> Anna Maria Calce</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research focused on the capability of health tourism to improve the economic and financial performance of healthcare companies.

Its features and limitation effects are today widespread basics throughout whole scientific thought. This article brings Gödel’s achievement into question by the definition of the refutability predicate as a number-theoretical statement. We develop proof of invalidity of Theorem VI in Gödel’s 1931, the so-called Gödel’s first incompleteness theorem, in two steps: defining refutability within the same recursive status as provability and showing that as a consequence propositions (15) and (16), derived from definition 8.1 in Gödel’s 1931, are false and unacceptable for the system. The achievement of their falsity blocks the derivation of Theorem VI, which turns out to be therefore invalid, together with all the depending theorems. This article opens up thus new perspectives for mathematical research and for the overall scientific reasoning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6del%20numbering" title="Gödel numbering">Gödel numbering</a>, <a href="https://publications.waset.org/abstracts/search?q=incompleteness" title=" incompleteness"> incompleteness</a>, <a href="https://publications.waset.org/abstracts/search?q=provability%20predicate" title=" provability predicate"> provability predicate</a>, <a href="https://publications.waset.org/abstracts/search?q=refutability%20predicate" title=" refutability predicate"> refutability predicate</a> </p> <a href="https://publications.waset.org/abstracts/55179/from-the-recursive-definition-of-refutability-to-the-invalidity-of-godels-1931-incompleteness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55179.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">188</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">48</span> Introducing Thermodynamic Variables through Scientific Inquiry for Engineering Students </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Utreras">Paola Utreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Yazmina%20Olmos"> Yazmina Olmos</a>, <a href="https://publications.waset.org/abstracts/search?q=Loreto%20Sanhueza"> Loreto Sanhueza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work shows how the learning of physics is enriched with scientific inquiry practices, achieving learning that results in the use of higher-level cognitive skills. The activities, which were carried out with students of the 3rd semester of the courses of the Faculty of Sciences of the Engineering of the Austral University of Chile, focused on the understanding of the nature of the thermodynamic variables and how they relate to each other. This, through the analysis of atmospheric data obtained in the meteorological station Miraflores, located on the campus. The proposed activities consisted of the elaboration of time series, linear analysis of variables, as well as the analysis of frequencies and periods. From their results, the students reached conclusions associated with the nature of the thermodynamic variables studied and the relationships between them, to finally make public their results in a report using scientific writing standards. It is observed that introducing topics that are close to them, interesting and which affect their daily lives allows a better understanding of the subjects, which is reflected in higher levels of approval and motivation for the subject. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basic%20sciences" title="basic sciences">basic sciences</a>, <a href="https://publications.waset.org/abstracts/search?q=inquiry-based%20learning" title=" inquiry-based learning"> inquiry-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20inquiry" title=" scientific inquiry"> scientific inquiry</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamics" title=" thermodynamics"> thermodynamics</a> </p> <a href="https://publications.waset.org/abstracts/67041/introducing-thermodynamic-variables-through-scientific-inquiry-for-engineering-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67041.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">258</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">47</span> Analysis of Energy Required for the Massive Incorporation of Electric Buses in the City of Ambato - Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Quintana">Paola Quintana</a>, <a href="https://publications.waset.org/abstracts/search?q=Ang%C3%A9lica%20Vaca"> Angélica Vaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebasti%C3%A1n%20Villacres"> Sebastián Villacres</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Acurio"> Henry Acurio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecuador through the Organic Law of Energy Efficiency establishes that "Starting in the year 2025, all vehicles that are incorporated into the urban and inter-parroquial public transport service must only be electric”, this marks a foundation for the introduction of electric mobility in the country.

The classification capability was compared with the flood hazard mapping River Basin Plans (PAI) designed by the Italian Institute for Environmental Research and Defence, ISPRA (Istituto Superiore per la Protezione e la Ricerca Ambientale). The study area of Piemonte, an Italian region, has been considered without loss of generality. The frequency ratios may be used as a standalone block to model the flood hazard mapping.

The transportation sector is a significant consumer of fossil fuels and contributes significantly to greenhouse gas emissions. The current challenge is to find ways to reduce the use of fossil fuels in transportation. In Ecuador, where 92% of electricity is generated from clean sources, the concept of e-mobility is considered an attractive alternative to address the challenge of sustainable mobility. The proposal is to migrate from combustion-powered vehicles to electric vehicles in the electric companies of Ecuador, using a methodology to standardize criteria, determine specific requirements, contrast technical characteristics, and estimate emission reductions. The results showed that there are three categories of vehicles that have electric counterparts suitable for performing activities under certain operation parameters inherent to current technology limitations but with a significant contribution to the reduction of annual CO₂ emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=electro%20mobility" title=" electro mobility"> electro mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20transportation" title=" sustainable transportation"> sustainable transportation</a> </p> <a href="https://publications.waset.org/abstracts/161828/proposal-of-methodology-based-on-technical-characterization-and-quantitative-contrast-of-co2-emissions-for-the-migration-to-electric-mobility-of-the-vehicle-fleet-case-study-of-electric-companies-in-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161828.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Luffa cylindrica as Alternative for Treatment of Waste in the Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obradith%20Caicedo">Obradith Caicedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Devia"> Paola Devia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Methylene blue (MB) and malachite green (MG) are substances commonly used in classrooms for academic purposes. Nevertheless, in most cases, there is no adequate disposal of this type of waste, their presence in the environment affects ecosystems due to the presence of color and the reduction of photosynthetic processes. In this work, we evaluated properties of fibers of Luffa cylindrica in removal from dyes of aqueous solutions through an adsorption process. The point of zero charge, acid and basic sites was also investigated. The best conditions of the adsorption process were determined under a discontinuous system, evaluating an interval of the variables 2 3 : pH value, particle size of the adsorbent and contact time. The temperature (18ºC), agitation (220 rpm) and adsorbent dosage (10g/L) were constant. Measurements were made using UV- Visible spectrophotometry. The point of zero charge for Luffa cylindrica was 4,3. The number of acidic and basic sites was 2.441 meq/g and 1,009 meq/g respectively. These indicate a prevalence of acid groups. The maximum dye sorption was found to be at a pH of 5,5 (97,1 % for MB) and 5,0 (97,7% for MG) and particle size of the adsorbent 850 µm. The equilibrium uptake was attained within 60 min. With this study, it has been shown that Luffa cylindrica can be used as efficient adsorbent for the removal of methylene blue, and malachite green from aqueous solution in classrooms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20removal" title=" dye removal"> dye removal</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20adsorbents" title=" low-cost adsorbents"> low-cost adsorbents</a>, <a href="https://publications.waset.org/abstracts/search?q=Luffa%20cylindrical" title=" Luffa cylindrical"> Luffa cylindrical</a> </p> <a href="https://publications.waset.org/abstracts/71344/luffa-cylindrica-as-alternative-for-treatment-of-waste-in-the-classroom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71344.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">190</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">43</span> Investigations on the Seismic Performance of Hot-Finished Hollow Steel Sections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Pannuzzo">Paola Pannuzzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tak-Ming%20Chan"> Tak-Ming Chan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In seismic applications, hollow steel sections show, beyond undeniable esthetical appeal, promising structural advantages since, unlike open section counterparts, they are not susceptible to weak-axis and lateral-torsional buckling. In particular, hot-finished hollow steel sections have homogeneous material properties and favorable ductility but have been underutilized for cyclic bending. The main reason is that the parameters affecting their hysteretic behaviors are not yet well understood and, consequently, are not well exploited in existing codes of practice. Therefore, experimental investigations have been conducted on a wide range of hot-finished rectangular hollow section beams with the aim to providing basic knowledge for evaluating their seismic performance. The section geometry (width-to-thickness and depth-to-thickness ratios) and the type of loading (monotonic and cyclic) have been chosen as the key parameters to investigate the cyclic effect on the rotational capacity and to highlight the differences between monotonic and cyclic load conditions. The test results provide information on the parameters that affect the cyclic performance of hot-finished hollow steel beams and can be used to assess the design provisions stipulated in the current seismic codes of practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending" title="bending">bending</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20test" title=" cyclic test"> cyclic test</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20sections" title=" hollow sections"> hollow sections</a>, <a href="https://publications.waset.org/abstracts/search?q=hot-finished%20sections" title=" hot-finished sections"> hot-finished sections</a> </p> <a href="https://publications.waset.org/abstracts/112114/investigations-on-the-seismic-performance-of-hot-finished-hollow-steel-sections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112114.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">154</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">42</span> Virtual Conciliation in Colombia: Evaluation of Maturity Level within the Framework of E-Government</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Paola%20Forero%20Pach%C3%B3n">Jenny Paola Forero Pachón</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Cristina%20Gamboa%20Sarmiento"> Sonia Cristina Gamboa Sarmiento</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20G%C3%B3mez%20Fl%C3%B3rez"> Luis Carlos Gómez Flórez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Colombian government has defined an e-government strategy to take advantage of Information Technologies (IT) in order to contribute to the building of a more efficient, transparent and participative State that provides better services to citizens and businesses. In this regard, the Justice sector is one of the government sectors where IT has generated more expectation considering that the country has a judicial processes backlog. This situation has led to the search for alternative forms of access to justice that speed up the process while providing a low cost for citizens. To this end, the Colombian government has authorized the use of Alternative Dispute Resolution methods (ADR), a remedy where disputes can be resolved more quickly compared to judicial processes while facilitating greater communication between the parties, without recourse to judicial authority. One of these methods is conciliation, which includes a special modality that takes advantage of IT for the development of itself known as virtual conciliation. With this option the conciliation is supported by information systems, applications or platforms and communications are provided through it. This paper evaluates the level of maturity in how the service of virtual conciliation is under the framework of this strategy. This evaluation is carried out considering Shahkooh's 5-phase model for e-government. As a result, it is evident that in the context of conciliation, maturity does not reach the necessary level in the model so that it can be considered as virtual conciliation; therefore, it is necessary to define strategies to maximize the potential of IT in this context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20dispute%20resolution" title="alternative dispute resolution">alternative dispute resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=e-government" title=" e-government"> e-government</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluation%20of%20maturity" title=" evaluation of maturity"> evaluation of maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahkooh%20model" title=" Shahkooh model"> Shahkooh model</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20conciliation" title=" virtual conciliation"> virtual conciliation</a> </p> <a href="https://publications.waset.org/abstracts/92453/virtual-conciliation-in-colombia-evaluation-of-maturity-level-within-the-framework-of-e-government" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92453.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">253</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">41</span> Energy Mutual Funds: The Behavior of Environmental, Social and Governance Funds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Paola%20Micheli">Anna Paola Micheli</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Maria%20Calce"> Anna Maria Calce</a>, <a href="https://publications.waset.org/abstracts/search?q=Loris%20Di%20Nallo"> Loris Di Nallo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainable finance identifies the process that leads, in the adoption of investment decisions, to take into account environmental and social factors, with the aim of orienting investments towards sustainable and long-term activities. Considering that the topic is at the center of the interest of national agendas, long-term investments will no longer be analyzed only by looking at financial data, but environmental, social, and governance (ESG) factors will be increasingly important and will play a fundamental role in determining the risk and return of an investment. Although this perspective does not deny the orientation to profit, ESG mutual funds represent sustainable finance applied to the world of mutual funds. So the goal of this paper is to verify this attitude, in particular in the energy sector. The choice of the sector is not casual: ESG is the acronym for environmental, social, and governance, and energy companies are strictly related to the environmental theme. The methodology adopted leads to a comparison between a sample of ESG funds and a sample of ESG funds with similar characteristics, using the most important indicators of literature: yield, standard deviation, and Sharpe index. The analysis is focused on equity funds. Results that are partial, due to the lack of historicity, show a good performance of ESG funds, testifying how a sustainable approach does not necessarily mean lower profits. It is clear that these first findings do not involve an absolute preference for ESG funds in terms of performance because the persistence of results is requested. Furthermore, these findings are to be verified in other sectors and in bond funds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mutual%20funds" title="mutual funds">mutual funds</a>, <a href="https://publications.waset.org/abstracts/search?q=ESG" title=" ESG"> ESG</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/144170/energy-mutual-funds-the-behavior-of-environmental-social-and-governance-funds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Valorization of the Waste Generated in Building Energy-Efficiency Rehabilitation Works as Raw Materials for Gypsum Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Villoria%20Saez">Paola Villoria Saez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Del%20Rio%20Merino"> Mercedes Del Rio Merino</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Santacruz%20Astorqui"> Jaime Santacruz Astorqui</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> In construction the Circular Economy covers the whole cycle of the building construction: from production and consumption to waste management and the market for secondary raw materials. The circular economy will definitely contribute to 'closing the loop' of construction product lifecycles through greater recycling and re-use, helping to build a market for reused construction materials salvaged from demolition sites, boosting global competitiveness and fostering sustainable economic growth. In this context, this paper presents the latest research of 'Waste to resources (W2R)' project funded by the Spanish Government, which seeks new solutions to improve energy efficiency in buildings by developing new building materials and products that are less expensive, more durable, with higher quality and more environmentally friendly. This project differs from others as its main objective is to reduce to almost zero the Construction and Demolition Waste (CDW) generated in building rehabilitation works. In order to achieve this objective, the group is looking for new ways of CDW recycling as raw materials for new conglomerate materials. With these new materials, construction elements reducing building energy consumption will be proposed. In this paper, the results obtained in the project are presented. Several tests were performed to gypsum samples containing different percentages of CDW waste generated in Spanish building retroffiting works. Results were further analyzed and one of the gypsum composites was highlighted and discussed.

The empirical study was run in the context of numerical estimation. Participants saw a two-digit number together with a collection of cars. They had to indicate whether the stimuli collection was larger or smaller than the number. The two-digit numbers ranged from 12 to 27, and collections included 3-36 cars. The presentation of the collections was dynamic (each car moved 30 deg. per second on the right). Half the collections were smaller collections (including fewer than 20 cars), and the other collections were larger collections (i.e., more than 20 cars). Splits between the number of cars in a collection and the two-digit number were either small (± 1 or 2 units; e.g., the collection included 17 cars and the two-digit number was 19) or larger (± 8 or 9 units; e.g., 17 cars and '9'). Half the collections included more items (and half fewer items) than the number indicated by the two-digit number. Before and after each trial, participants saw an image inducing negative emotions (e.g., mutilations) or neutral emotions (e.g., candle) selected from International Affective Picture System (IAPS). At the end of each trial, participants had to say if the second picture was the same as or different from the first. Results showed different effects of emotions on RTs and percent errors. Participants’ performance was modulated by emotions. They were slower on negative trials compared to the neutral trials, especially on the most difficult items. They errored more on small-split than on large-split problems. Moreover, participants highly overestimated the number of cars when in a negative emotional state. These findings suggest that emotions influence numerical estimation, that effects of emotion in estimation interact with stimuli characteristics. They have important implications for understanding the role of emotions on estimation skills, and more generally, on how emotions influence cognition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drone%20operators" title="drone operators">drone operators</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion" title=" emotion"> emotion</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20estimation" title=" numerical estimation"> numerical estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=arithmetic" title=" arithmetic"> arithmetic</a> </p> <a href="https://publications.waset.org/abstracts/130421/the-influence-of-emotion-on-numerical-estimation-a-drone-operators-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130421.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">116</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">38</span> Process for Analyzing Information Security Risks Associated with the Incorporation of Online Dispute Resolution Systems in the Context of Conciliation in Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jefferson%20Camacho%20Mejia">Jefferson Camacho Mejia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Paola%20Forero%20Pachon"> Jenny Paola Forero Pachon</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20Gomez%20Florez"> Luis Carlos Gomez Florez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The innumerable possibilities offered by the use of Information Technology (IT) in the development of different socio-economic activities has made a change in the social paradigm and the emergence of the so-called information and knowledge society. The Colombian government, aware of this reality, has been promoting the use of IT as part of the E-government strategy adopted in the country. However, it is well known that the use of IT implies the existence of certain threats that put the security of information in the digital environment at risk. One of the priorities of the Colombian government is to improve access to alternative justice through IT, in particular, access to Alternative Dispute Resolution (ADR): conciliation, arbitration and friendly composition; by means of which it is sought that the citizens directly resolve their differences. To this end, a trend has been identified in the use of Online Dispute Resolution (ODR) systems, which extend the benefits of ADR to the digital environment through the use of IT. This article presents a process for the analysis of information security risks associated with the incorporation of ODR systems in the context of conciliation in Colombia, based on four fundamental stages identified in the literature: (I) Identification of assets, (II) Identification of threats and vulnerabilities (III) Estimation of the impact and 4) Estimation of risk levels. The methodological design adopted for this research was the grounded theory, since it involves interactions that are applied to a specific context and from the perspective of diverse participants. As a result of this investigation, the activities to be followed are defined to carry out an analysis of information security risks, in the context of the conciliation in Colombia supported by ODR systems, thus contributing to the estimation of the risks to make possible its subsequent treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20dispute%20resolution" title="alternative dispute resolution">alternative dispute resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=conciliation" title=" conciliation"> conciliation</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20dispute%20resolution%20systems" title=" online dispute resolution systems"> online dispute resolution systems</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20analysis" title=" risk analysis"> risk analysis</a> </p> <a href="https://publications.waset.org/abstracts/91655/process-for-analyzing-information-security-risks-associated-with-the-incorporation-of-online-dispute-resolution-systems-in-the-context-of-conciliation-in-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91655.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">239</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">37</span> The Quasar 3C 47:Extreme Population B Jetted Source with Double-Peaked Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shimeles%20Terefe%20Mengistue">Shimeles Terefe Mengistue</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Marziani"> Paola Marziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ascensi%C3%B3ndel%20Olmo"> Ascensióndel Olmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Perea"> Jaime Perea</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirjana%20Povi%C4%87"> Mirjana Pović</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The theory that rotating accretion disks are responsible for the broad emission-line profiles in quasars is frequently put forth; however, the presence of accretion disk (AD) in active galactic nuclei (AGN) had limited and indirect observational support. In order to evaluate the extent to which the AD is a source of the broad Balmer lines and high ionization UV lines in radio-loud (RL) AGN, we focused on an extremely jetted RL quasar, 3C 47 that clearly shows a double peaked profile. This work presents its optical spectra and UV observations from the HST/FOS covering the rest-frame spectral range from 2000 to 7000 \AA. The fit of the low ionization lines, Hbeta, Halpha and MgII2800 show profiles that are in very good agreement with a relativistic Keplerian AD model. The profile of the prototypical high ionization lines can also be modeled by the contribution of the AD, with additional components due to outflows and emissions from the innermost part of the narrow line regions (NLRs). A prominent fit of the resulting double peaked profiles were found and very important disk parameters of the disk have been determined using the Hbeta, Halpha and MgII2800 lines: the inner and outer radii (both in units of G/mbh, where mbh is the supermassive black hole), an inclination to the line of sight, the emissivity index and the local broadening parameter. In addition, the accretion parameters, /mbh and /lledd are also determined. This work indicates that the line profile of 3C 47 shows the most convincing direct evidence for the presence of a rotating AD in AGN and the broad, double-peaked profiles originate from this AD that surrounds an /mbh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20galactic%20nuclei" title="active galactic nuclei">active galactic nuclei</a>, <a href="https://publications.waset.org/abstracts/search?q=quasars" title=" quasars"> quasars</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20lines" title=" emission lines"> emission lines</a>, <a href="https://publications.waset.org/abstracts/search?q=Double-peaked" title=" Double-peaked"> Double-peaked</a>, <a href="https://publications.waset.org/abstracts/search?q=supermassive%20black%20hole" title=" supermassive black hole"> supermassive black hole</a> </p> <a href="https://publications.waset.org/abstracts/175551/the-quasar-3c-47extreme-population-b-jetted-source-with-double-peaked-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175551.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">75</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">36</span> Promoting Environmental Sustainability in the Workplace: The Be-Green Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Carbone">Elena Carbone</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Meneghetti"> Chiara Meneghetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Innocenti"> Ivan Innocenti</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Musicanti"> Monica Musicanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Volpe"> Paola Volpe</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Pazzaglia"> Francesca Pazzaglia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Promoting environmental sustainability is becoming a priority for organizations. Little is known, however, on the extent to which green workplace behaviors are linked, alongside organizational determinants, and also to various employees’ individual characteristics. The BE-GREEN research project, in collaboration with Eni S.p.A., aimed at investigating the relationship between the adoption of green workplace behaviors and various employees’ job-related and broader individual characteristics as well as organizational determinants. A sample of 513 Eni employees was administered a survey assessing the adoption of green workplace behaviors and the management of events (e.g., near-miss, unsafe conditions, weak signals) that could anticipate the occurrence of incidents with a harmful environmental impact. The survey also assessed employees’ job-related (e.g., proneness toward behaving pro-environmentally at work) and general (e.g., soft skills, connectedness to nature and environmental awareness) characteristics and perceived organizational support (e.g., environmental culture, leadership). Results showed that the adoption of green workplace behaviors was associated with employees’ proneness toward behaving pro-environmentally at work, and these factors were, in turn, influenced by broader individual characteristics related to soft skills as well as a connectedness to nature and environmental awareness, along with perceived organizational support. The management of events potentially anticipating the occurrence of incidents with a harmful environmental impact was mainly associated with perceived organizational support. These findings highlight how, alongside organizational determinants, different employees’ individual characteristics influence their adoption of green workplace behaviors, with important implications for the development of interventions tailored to promote environmental sustainability in organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20workplace%20behaviors" title="green workplace behaviors">green workplace behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20skills" title=" soft skills"> soft skills</a>, <a href="https://publications.waset.org/abstracts/search?q=connectedness%20to%20nature" title=" connectedness to nature"> connectedness to nature</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20awareness." title=" environmental awareness."> environmental awareness.</a> </p> <a href="https://publications.waset.org/abstracts/183318/promoting-environmental-sustainability-in-the-workplace-the-be-green-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183318.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">63</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">35</span> Information Security Risk Management in IT-Based Process Virtualization: A Methodological Design Based on Action Research </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jefferson%20Camacho%20Mej%C3%ADa">Jefferson Camacho Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Paola%20Forero%20Pach%C3%B3n"> Jenny Paola Forero Pachón</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20G%C3%B3mez%20Fl%C3%B3rez"> Luis Carlos Gómez Flórez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Action research is a qualitative research methodology, which leads the researcher to delve into the problems of a community in order to understand its needs in depth and finally, to propose actions that lead to a change of social paradigm. Although this methodology had its beginnings in the human sciences, it has attracted increasing interest and acceptance in the field of information systems research since the 1990s. The countless possibilities offered nowadays by the use of Information Technologies (IT) in the development of different socio-economic activities have meant a change of social paradigm and the emergence of the so-called information and knowledge society. According to this, governments, large corporations, small entrepreneurs and in general, organizations of all kinds are using IT to virtualize their processes, taking them from the physical environment to the digital environment. However, there is a potential risk for organizations related with exposing valuable information without an appropriate framework for protecting it. This paper shows progress in the development of a methodological design to manage the information security risks associated with the IT-based processes virtualization, by applying the principles of the action research methodology and it is the result of a systematic review of the scientific literature. This design consists of seven fundamental stages. These are distributed in the three stages described in the action research methodology: 1) Observe, 2) Analyze and 3) Take actions. Finally, this paper aims to offer an alternative tool to traditional information security management methodologies with a view to being applied specifically in the planning stage of IT-based process virtualization in order to foresee risks and to establish security controls before formulating IT solutions in any type of organization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=action%20research" title="action research">action research</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20technology" title=" information technology"> information technology</a>, <a href="https://publications.waset.org/abstracts/search?q=methodological%20design" title=" methodological design"> methodological design</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20virtualization" title=" process virtualization"> process virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/94383/information-security-risk-management-in-it-based-process-virtualization-a-methodological-design-based-on-action-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Installing Beehives in Solar Parks to Enhance Local Biodiversity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuria%20Rubio">Nuria Rubio</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Campo"> María Campo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Ruiz"> Joana Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Vecino"> Paola Vecino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renewable energies have been proposed for some years as a solution to the ecological crisis caused by traditional fuels. The installation of solar parks for electricity production is therefore necessary for a transition to cleaner energy. Additionally, spaces occupied by solar parks can be ideal places for biodiversity promotion consisting in controlled areas allowing free transit of numerous animal species in absence of phytosanitary products or other substances commonly used in rural areas. The main objective of this project is increasing local biodiversity. Secondary objectives include the installation of beehives with Apis mellifera iberiensis swarms (native honeybee species), the monitoring and periodic evaluation of the state of health and demographic progression of these swarms and study of biodiversity increase in these areas, mainly due to the presence of Apis mellifera iberiensis. Prior to bee-hives installation, a preliminary study of the area is carried out to quantify floral load, biocenosis and geo-climatological characteristics of the area of study for determining the optimal number of hives for the benefit of the local ecosystem. Once beehives set up, the bee-swarms health status is monitored and evaluated quarterly using monitoring systems. Parameters studies are weight, humidity inside the hive, external and internal temperature, and sound inside the hive. Furthermore, a biodiversity study of the area was conducted by direct observation and quantification of species (S) in the area of bee-foraging (1 km around the beehives). A great diversity of species has been detected in the area of study. Therefore, the population of Apis mellifera iberiensis is not displacing other pollinators in the area, on the contrary, results show that it is contributing to the pollination of the different plant species enhancing wild bees’ biodiversity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=honeybee" title=" honeybee"> honeybee</a>, <a href="https://publications.waset.org/abstracts/search?q=pollination" title=" pollination"> pollination</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20park" title=" solar park"> solar park</a> </p> <a href="https://publications.waset.org/abstracts/182137/installing-beehives-in-solar-parks-to-enhance-local-biodiversity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182137.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">54</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">33</span> Integrating Best Practices for Construction Waste in Quality Management Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Villoria%20S%C3%A1ez">Paola Villoria Sáez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercedes%20Del%20R%C3%ADo%20Merino"> Mercedes Del Río Merino</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Santa%20Cruz%20Astorqui"> Jaime Santa Cruz Astorqui</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Rodr%C3%ADguez%20S%C3%A1nchez"> Antonio Rodríguez Sánchez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Spanish construction industry generates large volumes of waste. 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">32</span> The Genesis of the Anomalous Sernio Fan (Valtellina, Northern Italy)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erika%20De%20Finis">Erika De Finis</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Gattinoni"> Paola Gattinoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Scesi"> Laura Scesi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Massive rock avalanches formed some of the largest landslide deposits on Earth and they represent one of the major geohazards in high-relief mountains. This paper interprets a very large sedimentary fan (the Sernio fan, Valtellina, Northern Italy), located 20 Km SW from Val Pola Rock avalanche (1987), as the deposit of a partial collapse of a Deep Seated Gravitational Slope Deformation (DSGSD), afterwards eroded and buried by debris flows. The proposed emplacement sequence has been reconstructed based on geomorphological, structural and mechanical evidences. The Sernio fan is actually considered anomalous with reference to the very high ratio between the fan area (about 4.5km2) and the basin area (about 3km2). The morphology of the fan area is characterised by steep slopes (dip about 20%) and the fan apex is extended for 1.8 km inside the small catchment basin. This sedimentary fan was originated by a landslide that interested a part of a large deep-seated gravitational slope deformation, involving a wide area of about 55 km². The main controlling factor is tectonic and it is related to the proximity to regional fault systems and the consequent occurrence of fault weak rocks (GSI locally lower than 10 with compressive stress lower than 20MPa). Moreover, the fan deposit shows sedimentary evidences of recent debris flow events. The best current explanation of the Sernio fan involves an initial failure of some hundreds of Mm3. The run-out was quite limited because of the morphology of Valtellina’s valley floor, and the deposit filled the main valley forming a landslide dam, as confirmed by the lacustrine deposits detected upstream the fan. Nowadays the debris flow events represent the main hazard in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anomalous%20sedimentary%20fans" title="anomalous sedimentary fans">anomalous sedimentary fans</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20seated%20gravitational%20slope%20deformation" title=" deep seated gravitational slope deformation"> deep seated gravitational slope deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Italy" title=" Italy"> Italy</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20avalanche" title=" rock avalanche"> rock avalanche</a> </p> <a href="https://publications.waset.org/abstracts/35984/the-genesis-of-the-anomalous-sernio-fan-valtellina-northern-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35984.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">476</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">31</span> Changing Misconceptions in Heat Transfer: A Problem Based Learning Approach for Engineering Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Utreras">Paola Utreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Yazmina%20Olmos"> Yazmina Olmos</a>, <a href="https://publications.waset.org/abstracts/search?q=Loreto%20Sanhueza"> Loreto Sanhueza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work has the purpose of study and incorporate Problem Based Learning (PBL) for engineering students, through the analysis of several thermal images of dwellings located in different geographical points of the Region de los Ríos, Chile. The students analyze how heat is transferred in and out of the houses and how is the relation between heat transfer and climatic conditions that affect each zone. As a result of this activity students are able to acquire significant learning in the unit of heat and temperature, and manage to reverse previous conceptual errors related with energy, temperature and heat. In addition, student are able to generate prototype solutions to increase thermal efficiency using low cost materials. Students make public their results in a report using scientific writing standards and in a science fair open to the entire university community. The methodology used to measure previous Conceptual Errors has been applying diagnostic tests with everyday questions that involve concepts of heat, temperature, work and energy, before the unit. After the unit the same evaluation is done in order that themselves are able to evidence the evolution in the construction of knowledge. As a result, we found that in the initial test, 90% of the students showed deficiencies in the concepts previously mentioned, and in the subsequent test 47% showed deficiencies, these percent ages differ between students who carry out the course for the first time and those who have performed this course previously in a traditional way. The methodology used to measure Significant Learning has been by comparing results in subsequent courses of thermodynamics among students who have received problem based learning and those who have received traditional training. We have observe that learning becomes meaningful when applied to the daily lives of students promoting internalization of knowledge and understanding through critical thinking. <p
