The outstanding properties as the Lower Critical Solution Temperature (LCST), hydrolytic cleavage and protonation/deprotonation cycle, govern the release and delivery mechanisms of payloads. In this contribution, we experimentally determine the load efficiency and release of antineoplastic Vincristine Sulfate into PNIPAM-Interpenetrated-Chitosan (PIntC) nanoparticles. Structural analysis was performed by Fourier Transform Infrared Spectroscopy (FT-IR) and Proton Nuclear Magnetic Resonance (1HNMR). ζ-Potential (ζ) and Hydrodynamic diameter (DH) measurements were monitored by Electrophoretic Mobility (EM) and Dynamic Light scattering (DLS) respectively. Mathematical analysis of the release pharmacokinetics reveals a three-phase model above LCST, while a monophasic of Vincristine release model was observed at 32 °C. Cytotoxic essays reveal a noticeable enhancement of Vincristine effectiveness at low drug concentration on HeLa cervix cancer and MDA-MB-231 breast cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=vincristine" title=" vincristine"> vincristine</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=PNIPAM" title=" PNIPAM"> PNIPAM</a> </p> <a href="https://publications.waset.org/abstracts/90050/smart-polymeric-nanoparticles-loaded-with-vincristine-sulfate-for-applications-in-breast-cancer-drug-delivery-in-mda-mb-231-and-mcf7-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90050.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">156</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">242</span> Assessing the Vulnerability Level in Coastal Communities in the Caribbean: A Case Study of San Pedro, Belize</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherry%20Ann%20Ganase">Sherry Ann Ganase</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Sookram"> Sandra Sookram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the vulnerability level to climate change is analysed using a comprehensive index, consisting of five pillars: human, social, natural, physical, and financial. A structural equation model is also applied to determine the indicators and relationships that exist between the observed environmental changes and the quality of life. Using survey data to model the results, a value of 0.382 is derived as the vulnerability level for San Pedro, where values closer to zero indicates lower vulnerability and values closer to one indicates higher vulnerability. The results showed the social pillar to be most vulnerable, with the indicator ‘participation’ ranked the highest in its cohort. Although, the environmental pillar is ranked as least vulnerable, the indicators ‘hazard’ and ‘biodiversity’ obtained scores closer to 0.4, suggesting that changes in the environment are occurring from natural and anthropogenic activities. These changes can negatively influence the quality of life as illustrated in the structural equation modelling. The study concludes by reporting on the need for collective action and participation by households in lowering vulnerability to ensure sustainable development and livelihood. <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=participation" title=" participation"> participation</a>, <a href="https://publications.waset.org/abstracts/search?q=San%20Pedro" title=" San Pedro"> San Pedro</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20model" title=" structural equation model"> structural equation model</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability%20index" title=" vulnerability index"> vulnerability index</a> </p> <a href="https://publications.waset.org/abstracts/34964/assessing-the-vulnerability-level-in-coastal-communities-in-the-caribbean-a-case-study-of-san-pedro-belize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34964.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">631</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">241</span> Identification of Novel Differentially Expressed and Co-Expressed Genes between Tumor and Adjacent Tissue in Prostate Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Enrique%20Bautista-Hinojosa">Luis Enrique Bautista-Hinojosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20A.%20Herrera"> Luis A.

Saravana Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction and Rationale: Increased scope of Physiotherapy (PT) practice also has contributed to research in the field of PT. It is essential to determine the production and quality of the clinical trials from India since, it may reflect the scientific growth of the profession. These trends can be taken as a baseline to measure our performance and also can be used as a guideline for the future trials. Objective: To quantify and analyze qualitatively the RCT’s from India from the period 2000-2013’ May, and classify data for the information process. Methods: Studies were searched in the Medline database using the key terms “India”, “Indian”, “Physiotherapy”. Clinical trials only with PT authors were included. Trials out of scope of PT practice and on animals were excluded. Retrieved valid articles were analyzed for published year, type of participants, area of study, PEDro score, outcome measure domains of impairment, activity, participation; ‘a priori’ sample size calculation, region, and explanation of the intervention. Result: 45 valid articles were retrieved from the year 2000-2013’ May. The majority of articles were done on symptomatic participants (81%). The frequencies of conditions repeated more were low back pain (n-7) and diabetes (n-4). PEDro score with mode 5 and upper limit of 8 and lower limit 4 was found. 97.2% of studies measure the outcome at the impairment level, 34% in activity level, and 27.8% in participation level. 29.7% of studies did ‘a priori’ sample size calculation. Correlation of year trend and PEDro score found to be not significant (p>.05). Individual PEDro item analysis showed, randomization (100%), concealment (33%) baseline (76%), blinding-subject, therapist, assessor (9.1%, 0%, 10%), follow-up (89%) ITT (15%), statistics between groups (100%), measures of variance (88 %). Conclusion: The trend shows an upward slope in terms of RCTs published from India which is a good indicator. The qualitative analysis showed some gaps in the clinical trial design, which can be expected to be, fulfilled by the future researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RCT" title="RCT">RCT</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDro" title=" PEDro"> PEDro</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title=" physical therapy"> physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/4227/quantitative-and-qualitative-analysis-of-randomized-controlled-trials-in-physiotherapy-from-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4227.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">239</span> Multidisciplinary and Multilevel Design Methodology of Unmanned Aerial Vehicles using Enhanced Collaborative Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20F.%20Albuquerque">Pedro F.

The concepts of weighting coefficient and a dynamic compatibility parameter are presented for the ECO architecture. A routine that calculates the aircraft performance for the user defined mission profile and vehicle’s performance requirements has been implemented using low fidelity models for the aerodynamics, stability, propulsion, weight, balance and flight performance. A benchmarking case study for evaluating the advantage of using a variable span wing within the optimization methodology developed is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary" title="multidisciplinary">multidisciplinary</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel" title=" multilevel"> multilevel</a>, <a href="https://publications.waset.org/abstracts/search?q=morphing" title=" morphing"> morphing</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20collaborative%20optimization" title=" enhanced collaborative optimization"> enhanced collaborative optimization</a> </p> <a href="https://publications.waset.org/abstracts/18259/multidisciplinary-and-multilevel-design-methodology-of-unmanned-aerial-vehicles-using-enhanced-collaborative-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18259.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">929</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">238</span> A Literature Review on the Effect of Industrial Clusters and the Absorptive Capacity on Innovation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Claver%20Cort%C3%A9s">Enrique Claver Cortés</a>, <a href="https://publications.waset.org/abstracts/search?q=Bartolom%C3%A9%20Marco%20Lajara"> Bartolomé Marco Lajara</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20S%C3%A1nchez%20Garc%C3%ADa"> Eduardo Sánchez García</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Seva%20Larrosa"> Pedro Seva Larrosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Encarnaci%C3%B3n%20Manresa%20Marhuenda"> Encarnación Manresa Marhuenda</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Ruiz%20Fern%C3%A1ndez"> Lorena Ruiz Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Poveda%20Pareja"> Esther Poveda Pareja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent decades, the analysis of the effects of clustering as an essential factor for the development of innovations and the competitiveness of enterprises has raised great interest in different areas. Nowadays, companies have access to almost all tangible and intangible resources located and/or developed in any country in the world. However, despite the obvious advantages that this situation entails for companies, their geographical location has shown itself, increasingly clearly, to be a fundamental factor that positively influences their innovative performance and competitiveness. Industrial clusters could represent a unique level of analysis, positioned between the individual company and the industry, which makes them an ideal unit of analysis to determine the effects derived from company membership of a cluster. Also, the absorptive capacity (hereinafter 'AC') can mediate the process of innovation development by companies located in a cluster. The transformation and exploitation of knowledge could have a mediating effect between knowledge acquisition and innovative performance. The main objective of this work is to determine the key factors that affect the degree of generation and use of knowledge from the environment by companies and, consequently, their innovative performance and competitiveness. The elements analyzed are the companies' membership of a cluster and the AC. To this end, 30 most relevant papers published on this subject in the "Web of Science" database have been reviewed. Our findings show that, within a cluster, the knowledge coming from the companies' environment can significantly influence their innovative performance and competitiveness, although in this relationship, the degree of access and exploitation of the companies to this knowledge plays a fundamental role, which depends on a series of elements both internal and external to the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorptive%20capacity" title="absorptive capacity">absorptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=clusters" title=" clusters"> clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a> </p> <a href="https://publications.waset.org/abstracts/122776/a-literature-review-on-the-effect-of-industrial-clusters-and-the-absorptive-capacity-on-innovation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122776.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">131</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">237</span> Sunglasses Frame: UV Protection beyond Lens Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Augusto%20P.%20Andrade">Augusto P.

Current sunglasses standards establish safe limits regarding lens transmittance in the 280 nm to 380 nm range. However, frames are additionally relevant in protecting the eyes from ultraviolet exposure. This study involves the use of a prototype that simulates backscattered light environments and quantifies the contribution of the frame as a function of the light that reaches the eye when wearing sunglasses. The prototype consists of an LED illuminated sphere, a mannequin head with optical sensors, and baseline and measurements are performed. A set of 29 samples was tested, and results show the variation of light blocking presented by different types of frames, ranging from 68% to 80%. This is still ongoing research. Prototype improvements for allowing albedo simulation, as well as the six types of sky simulation, are being implemented to show the intensity of UV light reaching the eye for several environments worldwide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sunglasses%20standards" title="sunglasses standards">sunglasses standards</a>, <a href="https://publications.waset.org/abstracts/search?q=sunglasses%20frame" title=" sunglasses frame"> sunglasses frame</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20protection" title=" ultraviolet protection"> ultraviolet protection</a>, <a href="https://publications.waset.org/abstracts/search?q=albedo" title=" albedo"> albedo</a> </p> <a href="https://publications.waset.org/abstracts/163501/sunglasses-frame-uv-protection-beyond-lens-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163501.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">103</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">236</span> Innovation Environments: A Comparison between Mexico and BRICS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pe%C3%B1a%20Aguilar%20Juan%20M.">Peña Aguilar Juan M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Arriaga%20Barrera%20H."> Arriaga Barrera H.</a>, <a href="https://publications.waset.org/abstracts/search?q=Vel%C3%A1zquez%20Alejos%20Miguel"> Velázquez Alejos Miguel</a>, <a href="https://publications.waset.org/abstracts/search?q=Genis%20Ernesto"> Genis Ernesto</a>, <a href="https://publications.waset.org/abstracts/search?q=Valencia%20P%C3%A9rez%20L.%20R."> Valencia Pérez L.

These spring elements are equipped with constitutive models to include independently the moment, shear force and axial force, respectively. These constitutive models are formulated based on damage mechanics and experimental test reported in the literature review. The mesh of the segmented tunnels was discretized in the software GID, and the nonlinear analyses were carried out in the finite element software ANSYS. These analyses provide the capacity curve of the primary and secondary lining of a segmented tunnel. Two numerical examples of segmented tunnels show the capability of the spring elements to release energy by the development of hinges. The first example is a segmental concrete lining discretized with frame elements loaded until hinges occurred in the lining. The second example is a tunnel with primary and secondary lining, discretized with a double ring frame model. The outer ring simulates the segmental concrete lining and the inner ring simulates the secondary cast-in-place concrete lining. Spring elements also modelled the joints between the segments in the circumferential direction and the ring joints, which connect parallel adjacent rings. The computed load vs displacement curves are congruent with numerical and experimental results reported in the literature review. It is shown that the modelling of a tunnel with primary and secondary lining with frame elements and springs provides reasonable results and save computational cost, comparing with 2D or 3D models equipped with smeared crack models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=hinges" title=" hinges"> hinges</a>, <a href="https://publications.waset.org/abstracts/search?q=lining" title=" lining"> lining</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a> </p> <a href="https://publications.waset.org/abstracts/56714/modelling-of-damage-as-hinges-in-segmented-tunnels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56714.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">390</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">234</span> Virtual Science Hub: An Open Source Platform to Enrich Science Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Barra">Enrique Barra</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Gordillo"> Aldo Gordillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Quemada"> Juan Quemada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the Virtual Science Hub platform.

During MT, a mirror is placed between the two upper limbs (UL), thus reflecting movements of the non- affected side as if it were the affected side. Objectives: The aim of this review is to analyze the evidence on the effec.tiveness of MT in the recovery of UL function in population with post chronic stroke. Methods: The literature search was carried out in PubMed, ISI Web of Science, and PEDro database. Inclusion criteria: a) studies that include individuals diagnosed with stroke for at least 6 months; b) intervention with MT in UL or comparing it with other interventions; c) articles published until 2023; d) articles published in English or Portuguese; e) randomized controlled studies. Exclusion criteria: a) animal studies; b) studies that do not provide a detailed description of the intervention; c) Studies using central electrical stimulation. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. Studies with < 4 on PEDro scale were excluded. Eighteen studies met all the inclusion criteria. Main results and conclusions: The quality of the studies varies between 5 and 8. One article compared muscular strength training (MST) with MT vs without MT and four articles compared the use of MT vs conventional therapy (CT), one study compared extracorporeal shock therapy (EST) with and without MT and another study compared functional electrical stimulation (FES), MT and biofeedback, three studies compared MT with Mesh Glove (MG) or Sham Therapy, five articles compared performing bimanual exercises with and without MT and three studies compared MT with virtual reality (VR) or robot training (RT). The assessment of changes in function and structure (International Classification of Functioning, Disability and Health parameter) was carried out, in each article, mainly using the Fugl Meyer Assessment-Upper Limb scale, activity and participation (International Classification of Functioning, Disability and Health parameter) were evaluated using different scales, in each study. The positive results were seen in these parameters, globally. Results suggest that MT is more effective than other therapies in motor recovery and function of the affected UL, than these techniques alone, although the results have been modest in most of the included studies. There is also a more significant improvement in the distal movements of the affected hand than in the rest of the UL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title="physical therapy">physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=mirror%20therapy" title=" mirror therapy"> mirror therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20stroke" title=" chronic stroke"> chronic stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20limb" title=" upper limb"> upper limb</a>, <a href="https://publications.waset.org/abstracts/search?q=hemiplegia" title=" hemiplegia"> hemiplegia</a> </p> <a href="https://publications.waset.org/abstracts/181912/perspectives-and-challenges-a-functional-bread-with-yeast-extract-to-improve-human-diet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181912.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">55</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">232</span> Undocumented Migrants on the Northern Border of Mexico: Social Imaginary, and Social Representations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20Enrique%20Jim%C3%A9nez%20Ya%C3%B1ez">César Enrique Jiménez Yañez</a>, <a href="https://publications.waset.org/abstracts/search?q=Yessica%20Martinez%20Soto"> Yessica Martinez Soto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, the phenomenon of undocumented migration in the northern border of Mexico is analyzed through the graphic representation of the experience of people who migrate in an undocumented way to the United States. 33 of them drew what it meant for them to migrate.

The development of Intelligent Tutoring Systems (ITS) may help to solve some of them by helping teachers to customize their classes according to the performance of the students in online courses. In this work, we propose the adaptation of a functional ITS based on Bloom’s taxonomy called <em>Sistema de Apoyo Generalizado para la Enseñanza Individualizada</em> (SAGE), to measure student’s metacognition and their emotional response based on Marzano’s taxonomy. The students and the system will share the control over the advance in the course, so they can improve their metacognitive skills. The system will not allow students to get access to subjects not mastered yet. The interaction between the system and the student will be implemented through Natural Language Processing techniques, thus avoiding the use of sensors to evaluate student’s response. The teacher will evaluate student’s knowledge utilization, which is equivalent to the last cognitive level in Marzano’s taxonomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligent%20tutoring%20systems" title="intelligent tutoring systems">intelligent tutoring systems</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20modelling" title=" student modelling"> student modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognition" title=" metacognition"> metacognition</a>, <a href="https://publications.waset.org/abstracts/search?q=affective%20computing" title=" affective computing"> affective computing</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title=" natural language processing"> natural language processing</a> </p> <a href="https://publications.waset.org/abstracts/96468/methodology-for-developing-an-intelligent-tutoring-system-based-on-marzanos-taxonomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96468.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">197</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">228</span> Affordable Aerodynamic Balance for Instrumentation in a Wind Tunnel Using Arduino</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Ferreira">Pedro Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Frugoli"> Alexandre Frugoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Frugoli"> Pedro Frugoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucio%20Leonardo"> Lucio Leonardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Thais%20Cavalheri"> Thais Cavalheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The teaching of fluid mechanics in engineering courses is, in general, a source of great difficulties for learning. The possibility of the use of experiments with didactic wind tunnels can facilitate the education of future professionals. The objective of this proposal is the development of a low-cost aerodynamic balance to be used in a didactic wind tunnel. The set is comprised of an Arduino microcontroller, programmed by an open source software, linked to load cells built by students from another project. The didactic wind tunnel is 5,0m long and the test area is 90,0 cm x 90,0 cm x 150,0 cm. The Weq® electric motor, model W-22 of 9,2 HP, moves a fan with nine blades, each blade 32,0 cm long. The Weq® frequency inverter, model WEGCFW 08 (Vector Inverter) is responsible for wind speed control and also for the motor inversion of the rotational direction. A flat-convex profile prototype of airfoil was tested by measuring the drag and lift forces for certain attack angles; the air flux conditions remained constant, monitored by a Pitot tube connected to a EXTECH® Instruments digital pressure differential manometer Model HD755. The results indicate a good agreement with the theory. The choice of all of the components of this proposal resulted in a low-cost product providing a high level of specific knowledge of mechanics of fluids, which may be a good alternative to teaching in countries with scarce educational resources. The system also allows the expansion to measure other parameters like fluid velocity, temperature, pressure as well as the possibility of automation of other functions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20balance" title="aerodynamic balance">aerodynamic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel"> wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20gauge" title=" strain gauge"> strain gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20cell" title=" load cell"> load cell</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino" title=" Arduino"> Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20education" title=" low-cost education"> low-cost education</a> </p> <a href="https://publications.waset.org/abstracts/51909/affordable-aerodynamic-balance-for-instrumentation-in-a-wind-tunnel-using-arduino" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51909.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">445</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">227</span> Evaluation of the Curricular Content Domain Related to Topics of Human Sexuality in Teachers of Public Elementary Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ali%20Asadi">Ahmed Ali Asadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20R.%20Martinez-Alvarado"> Julio R.

The engineering education in universities of a developing country that is in need of an increasing number of engineers carried out with quality and affordably, pose a difficult problem to solve. In Brazil, the political and economic scenario requires academic managers able to reduce costs without compromising the quality of education. Within this context, the elaboration of a physics principles teaching method with the construction of an electronic balance is proposed. First, a method to develop and construct a load cell through which the students can understand the physical principle of strain gauges and bridge circuit will be proposed. The load cell structure was made with aluminum 6351T6, in dimensions of 80 mm x 13 mm x 13 mm and for its instrumentation, a complete Wheatstone Bridge was assembled with strain gauges of 350 ohms. Additionally, the process involves the use of a software tool to document the prototypes (design circuits), the conditioning of the signal, a microcontroller, C language programming as well as the development of the prototype. The project also intends to use an open-source I/O board (Arduino Microcontroller). To design the circuit, the Fritizing software will be used and, to program the controller, an open-source software named IDE®. A load cell was chosen because strain gauges have accuracy and their use has several applications in the industry. A prototype was developed for this study, and it confirmed the affordability of this educational idea. Furthermore, the goal of this proposal is to motivate the students to understand the several possible applications in high technology of the use of load cells and microcontroller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arduino" title="Arduino">Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20cell" title=" load cell"> load cell</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost%20education" title=" low-cost education"> low-cost education</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20gauge" title=" strain gauge"> strain gauge</a> </p> <a href="https://publications.waset.org/abstracts/51943/a-low-cost-education-proposal-using-strain-gauges-and-arduino-to-develop-a-balance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51943.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">225</span> Development and Automation of Medium-Scale NFT Hydroponic Systems: Design Methodology and State of the Art Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Armando%20Gonz%C3%A1lez-Marin">Oscar Armando González-Marin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhon%20F.%20Rodr%C3%ADguez-Le%C3%B3n"> Jhon F.

In addition, the overexploitation of agricultural lands, combined with food and water scarcity, has highlighted the urgent need for sustainable cultivation methods. Hydroponics has emerged as a sustainable farming technique that enables plant cultivation using nutrient solutions without the requirement for traditional soil. Among hydroponic methods, the Nutrient Film Technique (NFT) facilitates plant growth by circulating a nutrient solution continuously. This approach allows the monitoring and precise control of nutritional parameters, with potential for automation and technological integration. This study aims to present the state of the art of automated NFT hydroponic systems, discussing their design methodologies and considerations for implementation. Moreover, a medium-scale NFT system developed at CICATA-QRO is introduced, detailing its current manual management and progress toward automation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroponics" title=" hydroponics"> hydroponics</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20film%20technique" title=" nutrient film technique"> nutrient film technique</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/192149/development-and-automation-of-medium-scale-nft-hydroponic-systems-design-methodology-and-state-of-the-art-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192149.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">39</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">224</span> Technological Developments to Reduce Wind Blade Turbine Levelized Cost of Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Miguel%20Cardoso%20Carneiro">Pedro Miguel Cardoso Carneiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Andr%C3%A9%20Nunes%20Borges"> Ricardo André Nunes Borges</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Pedro%20Soares%20Loureiro"> João Pedro Soares Loureiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Herm%C3%ADnio%20Maio%20Gra%C3%A7a%20Fernandes"> Hermínio Maio Graça Fernandes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wind energy has been exponentially growing over the last years and will allow countries to progress regarding the decarbonization objective. In parallel, the maintenance activities have also been increasing in consequence of ageing and deterioration of the wind farms. The time available for wind blade maintenance is given by the weather window that is based upon weather conditions. Most of the wind blade repair and maintenance activities require a narrow window of temperature and humidity. Due to this limitation, the current weather windows result only on approximately 35% days/year are used for maintenance, that takes place mostly during summertime. This limitation creates large economic losses in the energy production of the wind towers, since they can be inoperative or with the energy production output reduced for days or weeks due to existing damages. Another important aspect is that the maintenance costs are higher due to the high standby time and seasonality imposed on the technicians. To reduce the relevant maintenance costs of blades and energy loses some technological developments were carried out to significantly improve this reality. The focus of this activity was to develop a series of key developments to have in the near future a suspended access equipment that can operate in harsh conditions, wind rain, cold/hot environment. To this end we have identified key areas that need to be revised and require new solutions to be found; a habitat system, multi-configurable roof and floor, roof and floor interface to blade, secondary attachment solutions to the blade and to the tower. On this paper we will describe the advances produced during a national R&D project made in partnership with an end-user (Onrope) and a test center (ISQ). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20maintenance" title="wind turbine maintenance">wind turbine maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20reduction" title=" cost reduction"> cost reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20innovations" title=" technological innovations"> technological innovations</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20blade" title=" wind turbine blade"> wind turbine blade</a> </p> <a href="https://publications.waset.org/abstracts/150262/technological-developments-to-reduce-wind-blade-turbine-levelized-cost-of-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150262.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">93</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">223</span> Thickness Measurement and Void Detection in Concrete Elements through Ultrasonic Pulse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonel%20Lipa%20Cusi">Leonel Lipa Cusi</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Nestor%20Pasquel%20Carbajal"> Enrique Nestor Pasquel Carbajal</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Marina%20Navarro%20Alvarado"> Laura Marina Navarro Alvarado</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Del%20%C3%81lamo%20Carazas"> José Del Álamo Carazas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research analyses the accuracy of the ultrasound and the pulse echo ultrasound technic to find voids and to measure thickness of concrete elements.

In Puerto Rico, there is a permanent controversy on the conceptuation of what really involves a disability, also in when a chronic illness, like cancer, should be considered a disability. The aim of the research was to identify functional limitation in 50 women survivors of cancer. In turn, to know the meanings that 6 women attributed to cancer with a focus on functionality. We conducted a mix method research based on surveys and narratives. We administered the World Health Organization Disability Assessment, version 2.0, which obtained a Cronbach’s alpha of .949 on the general scale, and from .773 to .956 on the six domains. The domain that obtained the highest average was social participation (M= 33.89, SD= 20.434), but it was not significant in the disability percentage. Also, there was no significance in the disability percentage in the other five domains. In a matter of meanings, we conduct a semistructured interview to 6 participants. All of them do not refer to cancer as a disability, either they do not know that in Puerto Rico cancer is considered as a disability by the law. However, participants agree that cancer at the time of treatment and subsequent to it, has significant effects on functional limitations (fatigue, pain, cognitive limitations, and weakness, among others. Psychooncologic practice should encourage the constant assessment of the functionality to identify the needs that emerge from oncological diagnosis. So that psychosocial intervention could be considered as critical in cancer treatment to promote a better quality of life and well-being in a person with cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Puerto%20Rico" title=" Puerto Rico"> Puerto Rico</a>, <a href="https://publications.waset.org/abstracts/search?q=disability" title=" disability"> disability</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosocial%20approach" title=" psychosocial approach"> psychosocial approach</a> </p> <a href="https://publications.waset.org/abstracts/56125/cancer-and-disability-a-psychosocial-approach-in-puerto-rican-women-as-cancer-survivors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56125.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">278</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">221</span> Multidrug Therapies For HIV: Hybrid On-Off, Hysteresis On-Off Control and Simple STI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magno%20Enrique%20Mendoza%20Meza">Magno Enrique Mendoza Meza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the comparison of three control techniques: the hysteresis on-off control (HyOOC), the hybrid on-off control (HOOC) and the simple Structured Treatment Interruptions (sSTI).

To compare these techniques we use a cost functional that minimize the wild-type virus population and the mutant virus population, but the main objective is to minimize the systemic cost of treatment and maximize levels of healthy CD4+ T cells. HyOOC, HOOC, and sSTI are applied to the drug therapies using a reverse transcriptase and protease inhibitors; simulations show that these controls maintain the uninfected cells in a small, bounded neighborhood of a pre-specified level.

They foster logical organization and clarify idea relationships, potentially aiding medical students in critical thinking (to think clearly and rationally about what to do or what to believe). However, there are inconsistent claims about the use of CMs in undergraduate medical education. Our three research questions are: 1) What studies have been published on concept mapping in undergraduate medical education? 2) What was the impact of CMs on students’ critical thinking? 3) How and why have these interventions had an educational impact? Methods: Eight databases were systematically searched (plus a manual and an additional search were conducted). After eliminating duplicate entries, titles, and abstracts, and full-texts were independently screened by two authors. Data extraction and quality assessment of the studies were independently performed by two authors. Qualitative and quantitative data were integrated using mixed-methods. The results were reported using the structured approach to the reporting in healthcare education of evidence synthesis statement and BEME guidance. Results: Thirty-nine studies were included from 26 journals (19 quantitative, 8 qualitative and 12 mixed-methods studies). CMs were considered as a tool to promote critical thinking, both in the perception of students and tutors, as well as in assessing students’ knowledge and/or skills. In addition to their role as facilitators of knowledge integration and critical thinking, CMs were considered both teaching and learning methods. Conclusions: CMs are teaching and learning tools which seem to help medical students develop critical thinking. This is due to the flexibility of the tool as a facilitator of knowledge integration, as a learning and teaching method. The wide range of contexts, purposes, and variations in how CMs and instruments to assess critical thinking are used increase our confidence that the positive effects are consistent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concept%20map" title="concept map">concept map</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20education" title=" medical education"> medical education</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate" title=" undergraduate"> undergraduate</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title=" critical thinking"> critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=meaningful%20learning" title=" meaningful learning"> meaningful learning</a> </p> <a href="https://publications.waset.org/abstracts/172812/the-effectiveness-of-concept-mapping-as-a-tool-for-developing-critical-thinking-in-undergraduate-medical-education-a-beme-systematic-review-beme-guide-no-81" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172812.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">125</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">219</span> Scale Prototype to Estimate the Resistance to Lateral Displacement Buried Pipes and submerged in non-Cohesive Soils </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Casta%C3%B1eda">Enrique Castañeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Hernadez"> Tomas Hernadez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Ulloa"> Mario Ulloa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent studies related to submarine pipelines under high pressure, temperature and buried, forces us to make bibliographical and documentary research to make us of references applicable to our problem. This paper presents an experimental methodology to the implementation of results obtained in a scale model, bibliography soil mechanics and finite element simulation. The model consists of a tank of 0.60 x 0.90 x 0.60 basis equipped high side windows, tires and digital hardware devices for measuring different variables to be applied to the model, where the mechanical properties of the soil are determined, simulation of drag a pipeline buried in a non-cohesive seafloor of the Gulf of Mexico, estimate the failure surface and application of each of the variables for the determination of mechanical elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=static%20friction%20coefficient" title="static friction coefficient">static friction coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20passive%20force%20resistant%20soil" title=" maximum passive force resistant soil"> maximum passive force resistant soil</a>, <a href="https://publications.waset.org/abstracts/search?q=normal" title=" normal"> normal</a>, <a href="https://publications.waset.org/abstracts/search?q=tangential%20stress" title=" tangential stress"> tangential stress</a> </p> <a href="https://publications.waset.org/abstracts/41281/scale-prototype-to-estimate-the-resistance-to-lateral-displacement-buried-pipes-and-submerged-in-non-cohesive-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41281.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">218</span> Modeling Football Penalty Shootouts: How Improving Individual Performance Affects Team Performance and the Fairness of the ABAB Sequence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Enrique%20Sartor%20Del%20Giudice">Pablo Enrique Sartor Del Giudice</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Penalty shootouts often decide the outcome of important soccer matches. Although usually referred to as ”lotteries”, there is evidence that some national teams and clubs consistently perform better than others. The outcomes are therefore not explained just by mere luck, and therefore there are ways to improve the average performance of players, naturally at the expense of some sort of effort. In this article we study the payoff of player performance improvements in terms of the performance of the team as a whole. To do so we develop an analytical model with static individual performances, as well as Monte Carlo models that take into account the known influence of partial score and round number on individual performances. We find that within a range of usual values, the team performance improves above 70% faster than individual performances do. Using these models, we also estimate that the new ABBA penalty shootout ordering under test reduces almost all the known bias in favor of the first-shooting team under the current ABAB system. <p
