<p class="card-text"><strong>Abstract:</strong></p> The Well Born (Nascer Bem – in Portuguese) Program was created in the Hapvida health network with the aim of improving access to safe and quality prenatal care for users. In addition to offering a line of prenatal care, the inclusion of obstetric nursing and the decentralization of childbirth, bring security that professionals did not indicate the route of delivery for professional convenience. The introduction of the nursing consultation came to reinforce the care to our users, strengthening their bond and reception. In 2021, the program maintained an average of 40% of normal births in the north, northeast and central-west regions of Brazil, an average above that observed in the rest of the country's private health systems, around 20%. In addition, the neonatal hospitalization rate of this population remained around 5.1%, a figure below the national average. With these data, the “Nascer Bem” program is affirmed as a safe and effective strategy for the promotion of safe normal birth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality" title="quality">quality</a>, <a href="https://publications.waset.org/abstracts/search?q=safe" title=" safe"> safe</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal" title=" prenatal"> prenatal</a>, <a href="https://publications.waset.org/abstracts/search?q=obstetric%20nursing" title=" obstetric nursing"> obstetric nursing</a> </p> <a href="https://publications.waset.org/abstracts/153230/pilot-program-for-the-promotion-of-normal-childbirth-in-the-north-northeast-and-midwest-of-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153230.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">119</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">272</span> Schizophrenia in Childhood and Adolescence: Research Topics and Applied Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jhonas%20Geraldo%20Peixoto%20Flauzino">Jhonas Geraldo Peixoto Flauzino</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Pompeo%20Boechat%20Araujo"> Pedro Pompeo Boechat Araujo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexia%20Allis%20Rocha%20Lima"> Alexia Allis Rocha Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Bi%C3%A2ngulo%20Lacerda%20Chaves"> Giovanna Biângulo Lacerda Chaves</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Ryan%20Ferr%C3%A3o%20Chaves"> Victor Ryan Ferrão Chaves</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schizophrenia is characterized as a set of psychiatric signs and symptoms (syndrome) that commonly erupt in the stages of adolescence or early adulthood, being recognized as one of the most serious diseases, as it causes important problems during the life of the patient. carrier - both in mental health and in physical health and in social life. Objectives: This is an integrative literature review that aimed to verify what has been produced of scientific knowledge in the field of child and adolescent psychiatry regarding schizophrenia in these stages of life, correlated to the most discussed themes and methodologies of choice for the preparation of studies. Methods: Articles were selected from the following databases: Virtual Health Library and CAPES Journal Portal, published in the last five years; and on Google Scholar, published in 2021, totaling 62 works, searched in September 2021. Results: The studies focus mainly on diagnosis through the DSM-V (25.8%), on drug treatment (25.8%) and in psychotherapy (24.2%), most of them in the literature review format: integrative (27.4%) and systematic (24.2%). Conclusion: The themes and study methods are redundant, and do not cover in depth the immense aspects that encompass Schizophrenia in Childhood and Adolescence, giving attention to the disease in a general way or focusing on the adult patient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schizophrenia" title="schizophrenia">schizophrenia</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood" title=" childhood"> childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescence" title=" adolescence"> adolescence</a> </p> <a href="https://publications.waset.org/abstracts/148255/schizophrenia-in-childhood-and-adolescence-research-topics-and-applied-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148255.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">183</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">271</span> A New Criterion for Removal of Fouling Deposit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20B%C3%A4cker">D.

Objective: To determine the prevalence and characteristics of consumption of nutraceuticals in undergraduate students. Methodology: Cross-sectional study. It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">577</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">268</span> Technoscience in the Information Society</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20P.%20Moiseeva">A.

The usage of the ‘You Only Look Once’ model in the first layer of the process obtains information from the screen, translating this information into a video game description language known as “Video Game Description Language”; the agents take that as input to make decisions. For this, the state-of-the-art algorithms were tested and compared; Monte Carlo Tree Search and Rolling Horizon Evolutionary; in this case, Rolling Horizon Evolutionary shows a better performance. This approach’s main advantage is that a VGDL beforehand is unnecessary. It will be built on the fly and opens the road for using more games as a framework for AI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AI" title="AI">AI</a>, <a href="https://publications.waset.org/abstracts/search?q=MCTS" title=" MCTS"> MCTS</a>, <a href="https://publications.waset.org/abstracts/search?q=RHEA" title=" RHEA"> RHEA</a>, <a href="https://publications.waset.org/abstracts/search?q=Terraria" title=" Terraria"> Terraria</a>, <a href="https://publications.waset.org/abstracts/search?q=VGDL" title=" VGDL"> VGDL</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLOv5" title=" YOLOv5"> YOLOv5</a> </p> <a href="https://publications.waset.org/abstracts/168302/terraria-ai-yolo-interface-for-decision-making-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168302.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">96</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">266</span> Low-Cost VoIP University Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Henrique%20Rodrigues%20de%20Oliveira">Carlos Henrique Rodrigues de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20Costa%20Fonseca"> Luis Carlos Costa Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Caio%20de%20Castro%20Torres"> Caio de Castro Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gusm%C3%A3o%20Pereira"> Daniel Gusmão Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Ricardo%20Souza%20Ripardo"> Luiz Ricardo Souza Ripardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Magno%20Castro%20Moraes"> Magno Castro Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Ferreira%20Costa"> Ana Paula Ferreira Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Carlos%20Chaves%20Lima%20Junior"> Luiz Carlos Chaves Lima Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurelianny%20Almeida%20da%20Cunha"> Aurelianny Almeida da Cunha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> VoIP University is a communication solution based on the IP protocol.

The combination of European modernist ideas with American musical culture, which differed in many ways from European musical culture, led to unique results. During the 1920s and even more so in the 1930s, members of the Austrian-German artistic intelligentsia, particularly those of Jewish origin who felt insecure in their homeland, began to look for a safer place. The United States has become such a place for many, and many of them chose the second largest metropolis—Los Angeles. The most notable figure in this group was the modernist composer Arnold Schoenberg. Other famous musicians were conductors Otto Klemperer and Bruno Walter. The study focused on how these people acclimated to a city whose culture and business revolved around film production; what place the conductors Klemperer and Walter occupied in the city, state, and country; how Schoenberg, whose musical style was little understood by the American public, was able to realize himself; what path he took when he was accepted to two universities as a professor of counterpoint and composition; and whether he revised his own views on the development of Western music. Another aspect was the study of how the composer’s memory was preserved in the universities where he taught. The study is based primarily on materials found in four libraries of two universities located in Los Angeles, UCLA and USC, during my tenure as a visiting scholar at USC Thornton School of Music (August 2023), to be completed during my upcoming visit there in August-September 2024, as well as on interviews with people active in efforts to keep Schoenberg’s memory alive on the USC Campus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=los%20angeles" title="los angeles">los angeles</a>, <a href="https://publications.waset.org/abstracts/search?q=filmmaking" title=" filmmaking"> filmmaking</a>, <a href="https://publications.waset.org/abstracts/search?q=immigrant%20musicians" title=" immigrant musicians"> immigrant musicians</a>, <a href="https://publications.waset.org/abstracts/search?q=arnold%20schoenberg" title=" arnold schoenberg"> arnold schoenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=otto%20klemperer" title=" otto klemperer"> otto klemperer</a>, <a href="https://publications.waset.org/abstracts/search?q=bruno%20walter" title=" bruno walter"> bruno walter</a> </p> <a href="https://publications.waset.org/abstracts/187905/music-of-a-film-city-interwar-europe-in-los-angeles-1930s" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187905.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">26</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">264</span> Functions and Pragmatic Aspects of English Nonsense</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20V.%20Ursul">Natalia V.

Nonsense is usually defined as spoken or written words that have no meaning. However, this definition is likely to be outdated as any speech act is generated due to the speaker’s pragmatic reasons, thus it cannot be purely illogical or meaningless. In the current paper a new working definition of nonsense as a linguistic medium will be formulated; moreover, the pragmatic peculiarities of newly coined linguistic patterns and possible ways of their interpretation will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonsense" title="nonsense">nonsense</a>, <a href="https://publications.waset.org/abstracts/search?q=nonse%20verse" title=" nonse verse"> nonse verse</a>, <a href="https://publications.waset.org/abstracts/search?q=pragmatics" title=" pragmatics"> pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20act" title=" speech act"> speech act</a> </p> <a href="https://publications.waset.org/abstracts/36261/functions-and-pragmatic-aspects-of-english-nonsense" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36261.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">519</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">263</span> Numerical Methodology to Support the Development of a Double Chamber Syringe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Louren%C3%A7o%20Bastos">Lourenço Bastos</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipa%20Carneiro"> Filipa Carneiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Vale"> Bruno Vale</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Marques%20Joana%20Silva"> Rita Marques Joana Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Freitas"> Ricardo Freitas</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%82ngelo%20Marques"> Ângelo Marques</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Cortez"> Sara Cortez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberta%20Coelho"> Alberta Coelho</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Parreira"> Pedro Parreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Liliana%20Sousa"> Liliana Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Anabela%20Salgueiro"> Anabela Salgueiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Silva"> Bruno Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The process of flushing is considered to be an adequate technique to reduce the risk of infection during the clinical practice of venous catheterization. Nonetheless, there is still a lack of adhesion to this method, in part due to the complexity of this procedure. The project SeringaDuo aimed to develop an innovative double-chamber syringe for intravenous sequential administration of drugs and serums. This device served the purpose of improving the adherence to the practice, through the reduction of manipulations needed, which also improves patient safety, and though the promotion of flushing practice by health professionals, by simplifying this task. To assist on the development of this innovative syringe, a numerical methodology was developed and validated in order to predict the syringe’s mechanical and flow behavior during the fluids’ loading and administration phases, as well as to allow the material behavior evaluation during its production. For this, three commercial numerical simulation software was used, namely ABAQUS, ANSYS/FLUENT, and MOLDFLOW. This methodology aimed to evaluate the concepts feasibility and to optimize the geometries of the syringe’s components, creating this way an iterative process for product development based on numerical simulations, validated by the production of prototypes. Through this methodology, it was possible to achieve a final design that fulfils all the characteristics and specifications defined. This iterative process based on numerical simulations is a powerful tool for product development that allows obtaining fast and accurate results without the strict need for prototypes. An iterative process can be implemented, consisting of consecutive constructions and evaluations of new concepts, to obtain an optimized solution, which fulfils all the predefined specifications and requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Venous%20catheterization" title="Venous catheterization">Venous catheterization</a>, <a href="https://publications.waset.org/abstracts/search?q=flushing" title=" flushing"> flushing</a>, <a href="https://publications.waset.org/abstracts/search?q=syringe" title=" syringe"> syringe</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/122369/numerical-methodology-to-support-the-development-of-a-double-chamber-syringe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122369.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">167</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">262</span> Health Perceptions in Elderly Population, before and after COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20L%C3%B3pez%20Rey">María José López Rey</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%20Chaves%20Carrillo"> Mar Chaves Carrillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuela%20Caballero%20Guisado"> Manuela Caballero Guisado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The data presented here are part of a broader investigation on active population aging.

The project has been financed by the European Regional Development Funds and the Government of Extremadura. Here, we focus on aspects that have to do with the experience of health, especially during the COVID-19 pandemic, and how this has affected the population related to the main sociodemographic variables. In an exercise of methodological triangulation, thus providing robustness to the analysis, primary data, obtained from the survey designed ad hoc, are combined with other secondary data from various sources and studies carried out in Spain (Sociological Research Centre, and National Institute of Statistics). The survey was carried out on a representative sample of the population over 55 years old, coming from Extremadura. Among the findings, we must highlight the practical invariability of perceptions based on the main sociodemographic variables, as well as some differences indicated by the variables sex and age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging" title="aging">aging</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptions" title=" perceptions"> perceptions</a> </p> <a href="https://publications.waset.org/abstracts/142275/health-perceptions-in-elderly-population-before-and-after-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142275.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">261</span> Approximating a Funicular Shape with a Translational Surface, Example of a Glass Canopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rapha%C3%ABl%20Menard">Raphaël Menard</a>, <a href="https://publications.waset.org/abstracts/search?q=Etienne%20Fayette"> Etienne Fayette</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Azzopardi"> Paul Azzopardi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the method to generate the geometry of an actual glass canopy project in Rennes, France, by architect Bruno Gaudin, with aim to achieve the best structural efficiency possible using only quadrangle meshing.

We oﬀer a comprehensive analysis of Sobolev embedding theorems in fractional spaces and apply bifurcation theory within quaternionic dynamical systems to better understand the complex behaviors in fluid systems. Additionally, the research delves into energy dissipation mechanisms in turbulent flows through the framework of Besov spaces. Key mathematical tools, such as interpolation theory, Littlewood-Paley decomposition, and energy cascade models, are integrated to develop a robust theoretical approach to these problems. By addressing challenges related to the existence and smoothness of solutions, this work contributes to the ongoing exploration of the open Navier-Stokes problem, providing new insights into the intricate relationship between fluid dynamics and functional spaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=navier-stokes%20equations" title="navier-stokes equations">navier-stokes equations</a>, <a href="https://publications.waset.org/abstracts/search?q=hypercomplex%20bifurcations" title=" hypercomplex bifurcations"> hypercomplex bifurcations</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence" title=" turbulence"> turbulence</a>, <a href="https://publications.waset.org/abstracts/search?q=sobolev%20and%20besov%20space" title=" sobolev and besov space"> sobolev and besov space</a> </p> <a href="https://publications.waset.org/abstracts/193029/hypercomplex-dynamics-and-turbulent-flows-in-sobolev-and-besov-functional-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193029.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">14</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">259</span> Non–Geometric Sensitivities Using the Adjoint Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Hayashi">Marcelo Hayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Lima"> João Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chieregatti"> Bruno Chieregatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernani%20Volpe"> Ernani Volpe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adjoint method has been used as a successful tool to obtain sensitivity gradients in aerodynamic design and optimisation for many years.

The success of this treatment is directly related to anatase phase formation (TiO2 phase) which affects the cells growth. The aim of this study was to evaluate the phases formed in the nanotubes growth on the Ti-15Mo surface. Nanotubes were grown by electrochemical anodization of the alloy in ammonium fluoride based glycerol electrolyte for 24 hours at 20V. Then, the samples were annealed at 200°,400°, 450°, 500°, 600°, and 800° C for 1 hour. Contact angles measurements, scanning electron microscopy images and X rays diffraction analysis (XRD) were carried out for all samples. Raman Spectroscopy was used to evaluate TiO2 phases transformation in nanotubes samples as well. The results of XRD showed anatase formation for lower temperatures, while at 800 ° C the rutile phase was observed all over the surface. Raman spectra indicate that this phase transition occurs between 500 and 600 °C. The different phases formed have influenced the nanotubes morphologies, since higher annealing temperatures induced agglutination of the TiO2 layer, disrupting the tubular structure. On the other hand, the nanotubes drastically reduced the contact angle, regardless the annealing temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanotubes" title="nanotubes">nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2" title=" TiO2"> TiO2</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=Ti-15Mo" title=" Ti-15Mo"> Ti-15Mo</a> </p> <a href="https://publications.waset.org/abstracts/17561/tio2-formation-after-nanotubes-growth-on-ti-15mo-alloy-surface-for-different-annealing-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17561.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">384</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">257</span> Web-Content Analysis of the Major Spanish Tourist Destinations Evaluation by Russian Tourists</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Polkanova">Natalia Polkanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Kazakov"> Sergey Kazakov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the research, we proposed the set of factors of tourist destinations attractiveness in Spain and determined the factors that have the greatest impact on the positive perception of the tourist destination by Russian tourists; also, we examined what factors create the willingness for Russians to recommend this tourist destination to their friends and relatives.

These values provide autonomous lifetime of the node more than one year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gas%20sensors" title="Gas sensors">Gas sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20management" title=" power management"> power management</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a> </p> <a href="https://publications.waset.org/abstracts/26244/power-management-in-wireless-combustible-gas-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26244.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">724</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">255</span> Personal Perception of the Acoustic Properties of Three Different Rooms for Music Lessons</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Ivanova">Natalia Ivanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantin%20Adamov"> Konstantin Adamov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of acoustics in music classes made us analyse three music rooms in a Bulgarian school.

The results show differences in the preferences of older students compared to younger ones. Results of the survey show a correlation between older students’ preferences and the standard requirements.

Women’s physiological functions of reproduction and childbearing are viewed as closer to nature as a binary opposition to men, who have metaphorically and historically been associated with culture. To liberate from strictures of phallogocentric rhetoric, a radical critique of the categories of nature and culture must be undertaken. This paper proposes that nature writing in Margaret Atwood’s The Testaments is used subversively as a form of rebellion to disrupt the metaphorical relationship between women and nature. In tune with ecofeminist concerns, the imagery rewrites patriarchal paradigms of binary oppositions as the protagonists narrate a complex and plural relationship between nature and women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecofeminism" title="ecofeminism">ecofeminism</a>, <a href="https://publications.waset.org/abstracts/search?q=Margaret%20Atwood" title=" Margaret Atwood"> Margaret Atwood</a>, <a href="https://publications.waset.org/abstracts/search?q=nature%20writing" title=" nature writing"> nature writing</a>, <a href="https://publications.waset.org/abstracts/search?q=women%27s%20writing" title=" women's writing"> women's writing</a> </p> <a href="https://publications.waset.org/abstracts/136049/nature-writing-in-margaret-atwoods-the-testaments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136049.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">252</span> Application of Signature Verification Models for Document Recognition </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20M.%20Fedorov">Boris M.

The additional complexity of processing lies in the dynamic variability of the signature for each individual, as well as in the way information is processed because the signature refers to biometric data. The article discusses the issues of using artificial intelligence models in order to improve the quality of signature confirmation in document recognition.

The optical properties have been tailored with varying the solution concentration, the withdrawn speed, and the heat-treatment.

In Atwood’s The Testaments, nature can be seen as a background to the story as well as a metaphorical expression of the characters’ state of mind, nevertheless, the protagonists’ nature writing portrays conveys a curiosity to the pre-established sanctions of a docile garden, viewing nature as an autonomous entity, especially when they are away from the confinements of Gilead’s regime. The three narrating protagonists, Agnes, Aunt Lydia, and Nicole, use nature writing subversively as a form of rebellion. This paper investigates how the three protagonists narrate nature through an intimist point of view, with sensibility to observe the multiple relationships among humanity, nature, and the impositions of a theocratic ultra conservative patriarchal society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contemporary%20literature" title="contemporary literature">contemporary literature</a>, <a href="https://publications.waset.org/abstracts/search?q=dystopias" title=" dystopias"> dystopias</a>, <a href="https://publications.waset.org/abstracts/search?q=feminism" title=" feminism"> feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=women%E2%80%99s%20writing" title=" women’s writing"> women’s writing</a> </p> <a href="https://publications.waset.org/abstracts/136055/womens-contemporary-dystopias-feminist-protagonists-taking-back-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136055.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">169</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">247</span> Audio Information Retrieval in Mobile Environment with Fast Audio Classifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruno%20T.%20Gomes">Bruno T.

The main characteristic of the polymer used in EOR process is the increase in viscosity which pushes the oil outside of the reservoir. The elasticity could contribute in the drag of the oil that stays in the reservoir. Studying the elastic effect on the oil drop at the pore scale, bring an explanation if the addition of elastic force could mobilize the oil. This research explores if the contraction and expansion of the polymer in the pore scale may increase the elastic behavior of this kind of fluid. For that reason, this work simplified the pore geometry and build two simple geometries with micrometer lengths. Using source terms with the user define a function this work introduces the UCM model in the ANSYS fluent simulator with the purpose of evaluating the elastic effect of the polymer in a contraction and expansion geometry. Also, using the Eulerian multiphase model, this research considers the possibility that extra elastic force will show a deformation effect on the oil; for that reason, this work considers an oil drop on the upper wall of the geometry. Finally, all the simulations exhibit that at the pore scale conditions exist extra vortices at UCM model but is not possible to deform the oil completely and push it outside of the restrictions, also this research find the conditions for the oil displacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANSYS%20fluent" title="ANSYS
