technology makes it possible to, in one hand, communicate with various objects of the daily life through the Internet, and in the other, put these objects interacting with each other through this channel. Simultaneously, with the raise of smartphones as the most ubiquitous technology on persons lives, emerge new agents for these devices - Intelligent Personal Assistants. These agents have the goal of helping the user manage and organize his information as well as supporting the user in his/her day-to-day tasks. Moreover, other emergent concept is the Cloud Computing, which allows computation and storage to get out of the users devices, bringing benefits in terms of performance, security, interoperability and others. Connecting these three paradigms, in this work we propose an architecture for an intelligent system which provides an interface that assists the user on smart environments, informing, suggesting actions and allowing to manage the objects of his/her daily life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title="internet of things">internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud" title=" cloud"> cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20personal%20assistant" title=" intelligent personal assistant"> intelligent personal assistant</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a> </p> <a href="https://publications.waset.org/abstracts/21138/a-pervasive-system-architecture-for-smart-environments-in-internet-of-things-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21138.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">514</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">443</span> Port Governance Model by International Freight Forwarders’ Point of View: A Study at Port of Santos - Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20B.%20B.%20Vieira">Guilherme B.

Part of these studies consider the ports as business agglomerations and focuses on port governance. This is an important approach since the port performance is the result of activities performed by actors belonging to the port-logistics chain, which need to be properly coordinated. This coordination takes place through a port governance model. Given this context, this study aims to analyze the governance model of the port of Santos from the perspective of port customers. To do this, a closed-ended questionnaire based on a conceptual model that considers the key dimensions associated with port governance was applied to the international freight forwarders that operate in the port. The results show the applicability of the considered model and highlight improvement opportunities to be implemented at the port of Santos. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=port%20governance" title="port governance">port governance</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=Port%20of%20Santos" title=" Port of Santos"> Port of Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=customers%E2%80%99%20perception" title=" customers’ perception"> customers’ perception</a> </p> <a href="https://publications.waset.org/abstracts/14167/port-governance-model-by-international-freight-forwarders-point-of-view-a-study-at-port-of-santos-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14167.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">452</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">442</span> Port Governance in Santos, Brazil: A Qualitative Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20B.%20B.%20Vieira">Guilherme B.

Since the fruit is perishable, it requires conservation methods to prolong its shelf life. Mango cubes were dehydrated at 40°C, 50°C and 60°C and by lyophilization, and the effect of these processes was investigated on the physicochemical characteristics (color and texture) of the products and monitoring of the main volatile compounds for the mango aroma. Volatile compounds were extracted by the SPME technique and analyzed in GC-MS system. Drying temperature at 60°C and lyophilization showed higher efficiency in retention of main volatile compounds, being 63.93% and 60.32% of the total concentration present in the fresh pulp, respectively. The freeze-drying process also presented features closer to the fresh mango in relation to color and texture, which contributes to greater acceptability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mango" title="mango">mango</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze%20drying" title=" freeze drying"> freeze drying</a>, <a href="https://publications.waset.org/abstracts/search?q=convection%20drying" title=" convection drying"> convection drying</a>, <a href="https://publications.waset.org/abstracts/search?q=aroma" title=" aroma"> aroma</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/183064/physicochemical-characteristics-and-evaluation-of-main-volatile-compounds-of-fresh-and-dehydrated-mango" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183064.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">64</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">439</span> Mechanical Characterization of Porcine Skin with the Finite Element Method Based Inverse Optimization Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Remache">Djamel Remache</a>, <a href="https://publications.waset.org/abstracts/search?q=Serge%20Dos%20Santos"> Serge Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Cliez"> Michael Cliez</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Gratton"> Michel Gratton</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Chabrand"> Patrick Chabrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Marie%20Rossi"> Jean-Marie Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Louis%20Milan"> Jean-Louis Milan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skin tissue is an inhomogeneous and anisotropic material. Uniaxial tensile testing is one of the primary testing techniques for the mechanical characterization of skin at large scales. In order to predict the mechanical behavior of materials, the direct or inverse analytical approaches are often used. However, in case of an inhomogeneous and anisotropic material as skin tissue, analytical approaches are not able to provide solutions. The numerical simulation is thus necessary. In this work, the uniaxial tensile test and the FEM (finite element method) based inverse method were used to identify the anisotropic mechanical properties of porcine skin tissue. The uniaxial tensile experiments were performed using Instron 8800 tensile machine®. The uniaxial tensile test was simulated with FEM, and then the inverse optimization approach (or the inverse calibration) was used for the identification of mechanical properties of the samples. Experimentally results were compared to finite element solutions. The results showed that the finite element model predictions of the mechanical behavior of the tested skin samples were well correlated with experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20skin%20tissue%20behavior" title="mechanical skin tissue behavior">mechanical skin tissue behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20tensile%20test" title=" uniaxial tensile test"> uniaxial tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20optimization%20approach" title=" inverse optimization approach"> inverse optimization approach</a> </p> <a href="https://publications.waset.org/abstracts/65920/mechanical-characterization-of-porcine-skin-with-the-finite-element-method-based-inverse-optimization-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65920.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">408</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">438</span> Anion Exchange Nanocomposite Membrane Doped with ZnO-Nanoparticles for Direct Methanol Alkaline Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phumlani%20Msomi">Phumlani Msomi</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Nonjola"> Patrick Nonjola</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Ndungu"> Patrick Ndungu</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Ramontja"> James Ramontja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A series of quaternized poly (2.6 dimethyl – 1.4 phenylene oxide)/ polysulfone (QPPO/PSF) blend anion exchange membrane (AEM) were successfully fabricated and characterized for methanol alkaline fuel cell application. Zinc Oxide (ZnO) nanoparticles were introduced in the polymer matrix to enhance the intrinsic properties of the AEM. To confirm successful fabrication, FT-IR spectroscopy and nuclear magnetic resonance (¹H NMR and HMBC ¹⁵N NMR) were used. The membrane properties were enhanced by the addition of ZnO nanoparticles. The addition of ZnO nanoparticles resulted to a higher ion exchange capacity (IEC) of 3.72 mmol.g⁻¹and a 30-fold ion conductivity (IC) increase of the nanocomposite due to no (zero (0)) methanol permeability at 30 °C and increased water uptake. The QPPO/PSF/2% ZnO composite retained over 80 % of its initial IC when evaluated for alkaline stability at room temperature. The maximum power output reached for the membrane electrode assembly (MEA) constructed with QPPO/PSF/2%ZnO is 69 mW.cm⁻², which is about three times more than the parent QPPO membrane. The above results indicate that QPPO/PSF-ZnO is a good candidate as an anion exchange membrane for fuel cell application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anion%20exchange%20membrane" title="anion exchange membrane">anion exchange membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell" title=" fuel cell"> fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a> </p> <a href="https://publications.waset.org/abstracts/75947/anion-exchange-nanocomposite-membrane-doped-with-zno-nanoparticles-for-direct-methanol-alkaline-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75947.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">272</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">437</span> Plastic Pellets in Santa Cruz Dos Navegantes Beach, Brazil, in the Winter of 2019</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Vasques%20Ribeiro">Victor Vasques Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Santa Cruz dos Navegantes beach is located in the city of Guarujá, in the central portion of the coast of the state of São Paulo. Next to this beach is located the Channel of the Port of Santos, configured as a source of plastic pellets for marine environments. On sandy beaches near the sources, especially during the winter and after cold front entrance events, the amounts of pellets can be very high. This study aimed to determine the influence of a cold front entry event of the winter of 2019 on the amount of pellets found on Santa Cruz dos Navegantes beach, besides assuming the proximity of the sources. During six consecutive collection campaigns, three of which were previous and three after the cold front entry peak, 30.0 square meters of surface sediments were sampled in each campaign. The color and shape of the pellets were determined to assume the length of the permanence of these granules in the marine environment and, consequently, the proximity of the sources. This beach was considered ideal for this type of research. The pellet pollution index (PPI) was from moderate to very high right after the peak of the cold front entry. The cold front peak event significantly influenced the amount of pellets found on the beach of Santa Cruz dos Navegantes. The factors that can bury the pellets in the sediments were classified as low when compared to other beaches in the region. Most of the pellets found were recently produced and lost to aquatic environments. Like the other beaches near Santos Bay, Santa Cruz dos Navegantes beach receives significant amounts of pellets that have nearby origins. Therefore, it was supposed that the activities of the Santos port complex are sources of pellets for the marine environment. This pollution can be further worsened in certain meteoceanographic events. The beaches of this region need to be constantly monitored and evaluated for pollution by pellets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beach" title="beach">beach</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20front" title=" cold front"> cold front</a>, <a href="https://publications.waset.org/abstracts/search?q=pellets" title=" pellets"> pellets</a>, <a href="https://publications.waset.org/abstracts/search?q=sources" title=" sources"> sources</a> </p> <a href="https://publications.waset.org/abstracts/123407/plastic-pellets-in-santa-cruz-dos-navegantes-beach-brazil-in-the-winter-of-2019" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123407.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">193</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">436</span> Acute Intraperitoneal Toxicity of Sesbania grandiflora (Katuray) Methanolic Flower Extract in Swiss Albino Mice </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levylee%20Bautista">Levylee Bautista</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawn%20Grace%20Santos"> Dawn Grace Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Aishwarya%20Veluchamy"> Aishwarya Veluchamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesusa%20Santos"> Jesusa Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghafoor%20Haque"> Ghafoor Haque</a>, <a href="https://publications.waset.org/abstracts/search?q=Jr.%20I"> Jr. I</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodolfo%20Rafael"> Rodolfo Rafael</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sesbania grandiflora is widely used in traditional medicine to treat a wide range of ailments. Assessment of its toxic properties is hence crucial when considering public health protection because exposure to plant extracts may pose adverse effects on consumers. This study aimed to investigate the acute intraperitoneal toxicity of S. grandiflora flower methanolic extract (SGFME) in Swiss albino mice. Four different concentrations (11.25, 22.5, 40, and 90 mg/kg) of SGFME were administered intraperitoneally and immediate behavioral and clinical signs were observed. All concentrations of SGFME-treated mice exhibited gasping and faster respiratory rate, writhing, reddening and fanning of the ears, paralysis of the hind leg, and mortality. Such reactions may be attributed to the histamine and saponin content of S. grandiflora. Results of this study suggests that intraperitoneal administration of SGFME produced significant adverse effect in mice, therefore, caution should be exercised in using it as herbal remedy since there is little control over its quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20toxicity%20test" title="acute toxicity test">acute toxicity test</a>, <a href="https://publications.waset.org/abstracts/search?q=histamine" title=" histamine"> histamine</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesbania%20grandiflora" title=" Sesbania grandiflora"> Sesbania grandiflora</a> </p> <a href="https://publications.waset.org/abstracts/128585/acute-intraperitoneal-toxicity-of-sesbania-grandiflora-katuray-methanolic-flower-extract-in-swiss-albino-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128585.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">435</span> SisGeo: Support System for the Research of Georeferenced Comparisons Applied to Professional and Academic Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruno%20D.%20Souza">Bruno D.

Thus, evolution and improvement in this technology are mandatory. Accordingly, satellite georeferenced systems need to accomplish the same evolution rhythm. Either GPS (Global Positioning System) or its similar Russian GLONASS (Global Navigation Satellite System) are system samples that offer us powerful tools to plot coordinates on the earth surface. The development of this research aims the study of several aspects related to use of GPS and GLONASS technologies, given its application and collected data improvement during geodetic data acquisition. So, both relevant theoretic and practical aspects are considered. In this context, at the theoretical part, the main systems' characteristics are shown, observing its similarities and differences. At the practical part, a series of experiences are performed and obtained data packages are compared in order to demonstrate equivalence or differences among them. The evaluation methodology targets both quantitative and qualitative analysis provided by GPS and GPS/GLONASS receptors. Meanwhile, a specific collected data storage system was developed to better compare and analyze them (SisGeo - Georeferenced Research Comparison Support System). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satellites" title="satellites">satellites</a>, <a href="https://publications.waset.org/abstracts/search?q=systems" title=" systems"> systems</a>, <a href="https://publications.waset.org/abstracts/search?q=applications" title=" applications"> applications</a>, <a href="https://publications.waset.org/abstracts/search?q=experiments" title=" experiments"> experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=receivers" title=" receivers"> receivers</a> </p> <a href="https://publications.waset.org/abstracts/87529/sisgeo-support-system-for-the-research-of-georeferenced-comparisons-applied-to-professional-and-academic-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87529.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">255</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">434</span> Simulation of the Collimator Plug Design for Prompt-Gamma Activation Analysis in the IEA-R1 Nuclear Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20G.%20Santos">Carlos G.

However, the installation of a PGAA system entails specific conditions such as filtering the neutron beam according to the target and providing adequate shielding for both users and detectors. These requirements incur substantial costs, exceeding $100,000, including manpower. Nevertheless, a cost-effective approach involves leveraging an existing neutron beam facility to create a hybrid system integrating PGAA and Neutron Tomography (NT). The IEA-R1 nuclear reactor at IPEN/USP possesses an NT facility with suitable conditions for adapting and implementing a PGAA device. The NT facility offers a thermal flux slightly colder and provides shielding for user protection. The key additional requirement involves designing detector shielding to mitigate high gamma ray background and safeguard the HPGe detector from neutron-induced damage. This study employs Monte Carlo simulations with the MCNP6 code to optimize the collimator plug for PGAA within the IEA-R1 NT facility. Three collimator models are proposed and simulated to assess their effectiveness in shielding gamma and neutron radiation from nucleon fission. The aim is to achieve a focused prompt-gamma signal while shielding ambient gamma radiation. The simulation results indicate that one of the proposed designs is particularly suitable for the PGAA-NT hybrid system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MCNP6.1" title="MCNP6.1">MCNP6.1</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron" title=" neutron"> neutron</a>, <a href="https://publications.waset.org/abstracts/search?q=prompt-gamma%20ray" title=" prompt-gamma ray"> prompt-gamma ray</a>, <a href="https://publications.waset.org/abstracts/search?q=prompt-gamma%20activation%20analysis" title=" prompt-gamma activation analysis"> prompt-gamma activation analysis</a> </p> <a href="https://publications.waset.org/abstracts/179265/simulation-of-the-collimator-plug-design-for-prompt-gamma-activation-analysis-in-the-iea-r1-nuclear-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179265.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">433</span> Endeavor in Management Process by Executive Dashboards: The Case of the Financial Directorship in Brazilian Navy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Quintal">R.

Its basic principle is to place cells on a scaffold capable of promoting cell functions, and for this purpose, polymeric nanoparticles have been successfully used due to the ability of some macro chains to mimic the extracellular matrix and influence cell functions. In general, nanoparticles require surface chemical modification to achieve cell adhesion, and recent advances in their synthesis include methods for modifying the ligand density and distribution onto nanoparticles surface. However, this work reports the development of biodegradable polymeric nanoparticles capable of promoting cellular adhesion without any surface chemical modification by ligands. Biocompatible and biodegradable nanoparticles based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) were synthesized by solvent evaporation method. The produced nanoparticles were small in size (85 and 125 nm) and colloidally stable against time in aqueous solution. Morphology evaluation showed their spherical shape with small polydispersity. Human osteoblast-like cells (MG63) were cultured in the presence of PHBHV nanoparticles, and growth kinetics were compared to those grown on tissue culture polystyrene (TCPS). Cell attachment on non-tissue culture polystyrene (non-TCPS) pre-coated with nanoparticles was assessed and compared to attachment on TCPS. These findings reveal the potential of PHBHV nanoparticles for cell adhesion and growth, without requiring a matrix ligand to support cells, to be used as scaffolds, in tissue engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title="tissue engineering">tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=PHBHV" title=" PHBHV"> PHBHV</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=cellular%20attachment" title=" cellular attachment"> cellular attachment</a> </p> <a href="https://publications.waset.org/abstracts/81789/engineering-ligand-free-biodegradable-based-nanoparticles-for-cell-attachment-and-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81789.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">210</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">431</span> In vivo Genotoxicity Testing of Sesbania Grandiflora (Katuray) Flower Methanolic Extract </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levylee%20Bautista">Levylee Bautista</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawn%20Grace%20Santos"> Dawn Grace Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Aishwarya%20Veluchamy"> Aishwarya Veluchamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesusa%20Santos"> Jesusa Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghafoor"> Ghafoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Jr.%20I%20Haque"> Jr. I Haque</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodolfo%20Rafael"> Rodolfo Rafael</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The booming interest in using natural compounds as an alternative to conventional medications has paved way to focus the attention on plants that provide rich sources of bioactive phytochemicals. For regulatory purposes, evaluation of the genotoxic effects of such alternatives is therefore empirical as part of the plant’s hazard assessment. Sesbania grandiflora is among the plants used as a traditional remedy in folk medicine and a subject of research for its medicinal benefits. This study aimed to evaluate the genotoxic potential induced by S. grandiflora flower methanol extract (SGFME) in terms of the frequency of micronucleus (MN) in polychromatic erythrocyte (PCE) (MNPCE) and PCE ratio employing the micronucleus assay. The frequency of MN was examined in bone marrow cells (BMCs) obtained from male Swiss albino mice exposed in vivo to four different concentrations (11.25, 22.5, 40, and 90 mg/kg) of SGFME and MMC (70 mg/kg; positive control) and sacrificed 24 hours post-intraperitoneal injection. Results showed a significant (p < 0.01) rate of MNPCEs for 11.25 and 22.5 tested concentrations of SGFME and is comparable with the MMC-treated mice. Although PCE ratio values in all doses of SGFME-treated mice were over 0.20, it is worth noting that 40 and 90 tested concentrations of SGFME-treated mice exhibited the lowest value, i.e., 0.22 and 0.28, respectively. The present study has demonstrated that S. grandiflora possesses genotoxic potential for murine BMCs. Such activity could be ascribed from the bioactive compounds present in S. grandiflora that require further isolation and characterization of the active molecules. Likewise, findings of this study warrant a caution of the use of S. grandiflora insomuch as further investigations do not demonstrate their safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title="genotoxicity">genotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=micronucleus" title=" micronucleus"> micronucleus</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemicals" title=" phytochemicals"> phytochemicals</a>, <a href="https://publications.waset.org/abstracts/search?q=Sesbania%20grandiflora" title=" Sesbania grandiflora"> Sesbania grandiflora</a> </p> <a href="https://publications.waset.org/abstracts/128583/in-vivo-genotoxicity-testing-of-sesbania-grandiflora-katuray-flower-methanolic-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128583.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">140</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">430</span> A Research on Determining the Viability of a Job Board Website for Refugees in Kenya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prince%20Mugoya">Prince Mugoya</a>, <a href="https://publications.waset.org/abstracts/search?q=Collins%20Oduor%20Ondiek"> Collins Oduor Ondiek</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Kanyi%20Wamuyu"> Patrick Kanyi Wamuyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Refugee Job Board Website is a web-based application that provides a platform for organizations to post jobs specifically for refugees.

Maternal sleep deprivation can trigger or aggravate psychosomatic problems such as depression, anxiety and stress that can directly influence maternal safety, with consequences for the baby's and mother's sleep. Such conditions can affect the family's quality of life and child development. Objective: To correlate maternal security with maternal state anxiety scores and the mother's and baby's total sleep time. Method: Cross-sectional study carried out with 96 mothers of babies aged 10 to 24 months, accompanied by nursing professionals linked to a Federal University in Northeast Brazil. Study variables were maternal security, maternal state anxiety scores, infant latency and sleep time, and total nocturnal sleep time of mother and infant. Maternal safety was calculated using a four-point Likert scale (1=not at all safe, 2=somewhat safe, 3=very safe, 4=completely safe). Maternal anxiety was measured by State-Trait Anxiety Inventory, state-anxiety subscale whose scores vary from 20 to 80 points, and the higher the score, the higher the anxiety levels. Scores below 33 are considered mild; from 33 to 49, moderate and above 49, high. As for the total nocturnal sleep time, values between 7-9 hours of sleep were considered adequate for mothers, and values between 9-12 hours for the baby, according to the guidelines of the National Sleep Foundation. For the sleep latency time, a time equal to or less than 20 min was considered adequate. It is noteworthy that the latency time and the time of night sleep of the mother and the baby were obtained by the mother's subjective report. To correlate the data, Spearman's correlation was used in the statistical package R version 3.6.3. Results: 96 women and babies participated, aged 22 to 38 years (mean 30.8) and 10 to 24 months (mean 14.7), respectively. The average of maternal security was 2.89 (unsafe); Mean maternal state anxiety scores were 43.75 (moderate anxiety). The babies' average sleep latency time was 39.6 min (>20 min). The mean sleep times of the mother and baby were, respectively, 6h and 42min and 8h and 19min, both less than the recommended nocturnal sleep time. Maternal security was positively correlated with maternal state anxiety scores (rh=266, p=0.009) and negatively correlated with infant sleep latency (rh= -0.30. P=0.003). Baby sleep time was positively correlated with maternal sleep time. (rh 0.46, p<0.001). Conclusion: The more secure the mothers considered themselves, the higher the anxiety scores and the shorter the baby's sleep latency. Also, the longer the baby sleeps, the longer the mother sleeps. Thus, interventions are needed to promote the quality and efficiency of sleep for both mother and baby. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep" title="sleep">sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=mother-child%20relations" title=" mother-child relations"> mother-child relations</a> </p> <a href="https://publications.waset.org/abstracts/167836/safety-and-maternal-anxiety-in-mothers-and-babys-sleep-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167836.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">102</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">428</span> 'Disability' and Suffering: The Case of Workers Affected by Repetitive Strain Injury/Work Related Musculoskeletal Disorder in a Removal from Work Situation in Santos, São Paulo, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Do%20Carmo%20Baracho%20De%20%20Alencar">Maria Do Carmo Baracho De Alencar</a>, <a href="https://publications.waset.org/abstracts/search?q=Marciene%20Campos%20%20Fialho"> Marciene Campos Fialho</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Do%20Carmo%20Vit%C3%B3rio%20Ramos"> Maria Do Carmo Vitório Ramos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The subjects affected by Repetitive Strain Injury/Work Related Musculoskeletal Disorder (RSI/WRMSD) face an everyday life marked by pain, feelings of worthlessness and incapacity caused by the disease, and aggravated often because of discrimination society. Aim: To investigate the experiences and feelings of workers affected by RSI/WRMSD in removal from work situations and to understand the repercussions on mental health. Methods: Clinical records of workers were consulted, opened from July 1, 2014, to July 1, 2015, at the Reference Center for Worker's Health, in Santos city-SP. Selection of workers affected by RSI /WRMSD and who had experienced the removal from work situation due to the disease, and invitation to participate in the study. Semi-structured and individual interviews were carried out based on a pre-elaborated script, and for thematic content analysis. Results: Of a total of 502 medical records, 157 were selected, and of these, 18 workers participated in the interviews, both gender, most of them with low education level, aged between 35 and 56 years, and from different professions. Diseases affected several physical body regions and some workers had more than one body region affected by chronic pain. In the testimonies emerged the psychic suffering by the process of illness at work, fear of dismissal, invisibility of pain, in medical expertise attendance, by the incapacity to perform tasks that were easily achievable, with feelings of uselessness, revolt, and injustice, among others. Conclusion: The workers need to be readapted to new life situations, and the study promotes reflections on the need for more interdisciplinary actions and of the Psychology to the workers affected by RSI/ WRMSD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=repetitive%20strain%20injury" title="repetitive strain injury">repetitive strain injury</a>, <a href="https://publications.waset.org/abstracts/search?q=cumulative%20trauma%20disorder" title=" cumulative trauma disorder"> cumulative trauma disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=absence%20from%20work" title=" absence from work"> absence from work</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=occupational%20health" title=" occupational health"> occupational health</a> </p> <a href="https://publications.waset.org/abstracts/85770/disability-and-suffering-the-case-of-workers-affected-by-repetitive-strain-injurywork-related-musculoskeletal-disorder-in-a-removal-from-work-situation-in-santos-sao-paulo-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85770.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">158</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">427</span> Use of Smartphone in Practical Classes to Facilitate Teaching and Learning of Microscopic Analysis and Interpretation of Tissues Sections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lise%20P.%20Lab%C3%A9jof">Lise P.

In this work, novel solid dispersions based on thermo- and pH-responsive poly(N-vinylcaprolactam-co-itaconic acid-co-ethylene- glycol dimethacrylate) hydrogel nanoparticles embedded in chitosan matrices were prepared via spray drying for controlled release of ketoprofen. Firstly, the hydrogel nanoparticles containing ketoprofen were prepared via precipitation polymerization and their stimuli-responsive behavior, thermal properties, chemical composition, encapsulation efficiency and morphology were characterized. Then, hydrogel nanoparticles with different particles size were embedded into chitosan matrices via spray-drying. Scanning electron microscopy (SEM) analyses were performed to investigate the particles size, dispersity and morphology. Finally, ketoprofen release profiles were studied as a function of pH and temperature. Chitosan/poly(NVCL-co-IA-co-EGDMA)-ketoprofen microparticles presented spherical shape, rough surface and pronounced agglomeration, indicating that hydrogels nanoparticles loaded with ketoprofen modified the surface of chitosan matrix. The maximum encapsulation efficiency of ketoprofen into hydrogel nanoparticles was 57.8% and the electrostatic interactions between amino groups from chitosan and carboxylic groups from hydrogel nanoparticles were able to control ketoprofen release. The hydrogel nanoparticles themselves were capable to retard the release of ketoprofen-loaded until 48h of in vitro release tests, while their incorporation into chitosan matrix achieved a maximum percentage of drug release of 45%, using a mass ratio of chitosan: poly(NVCL-co-IA-co-EGDMA equal to 10:7, and 69%, using a mass ratio of chitosan: poly(NVCL-co-IA-co-EGDMA equal to 5:2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogel%20nanoparticles" title="hydrogel nanoparticles">hydrogel nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28N-vinylcaprolactam-co-itaconic%20acid-co-ethylene-%20glycol%20dimethacrylate%29" title=" poly(N-vinylcaprolactam-co-itaconic acid-co-ethylene- glycol dimethacrylate)"> poly(N-vinylcaprolactam-co-itaconic acid-co-ethylene- glycol dimethacrylate)</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=ketoprofen" title=" ketoprofen"> ketoprofen</a>, <a href="https://publications.waset.org/abstracts/search?q=spray-drying" title=" spray-drying"> spray-drying</a> </p> <a href="https://publications.waset.org/abstracts/81767/polyn-vinylcaprolactam-co-itaconic-acid-co-ethylene-glycol-dimethacrylate-based-microgels-embedded-in-chitosan-matrix-for-controlled-release-of-ketoprofen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81767.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">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">425</span> The Use of Instagram as a Sales Tool by Small Fashion/Clothing Businesses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santos%20Andressa%20M.%20N.">Santos Andressa M.

The theoretical scope intended here is to identify how performance in police organizations has been studied. After deepening the analysis and focusing on management, it was possible to classify the articles into three levels: individual, organizational, and institutional. However, to our best knowledge, no studies were found that addressed the performance relationship between the levels, which can be seen as a suggestion for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=police%20management" title="police management">police management</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-level" title=" multi-level"> multi-level</a> </p> <a href="https://publications.waset.org/abstracts/153739/performance-in-police-organizations-approaches-from-the-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153739.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">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">418</span> Health Status Monitoring of COVID-19 Patient's through Blood Tests and Naïve-Bayes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Arias-Alcaide">Carlos Arias-Alcaide</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Soguero-Ruiz"> Cristina Soguero-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paloma%20Santos-%C3%81lvarez"> Paloma Santos-Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Adri%C3%A1n%20Garc%C3%ADa-Romero"> Adrián García-Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Inmaculada%20Mora-Jim%C3%A9nez"> Inmaculada Mora-Jiménez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysing clinical data with computers in such a way that have an impact on the practitioners’ workflow is a challenge nowadays.

A smart grid is an essential part of any smart city as both consumers and power utility companies benefit from the features provided by the power grid. In addition to advanced features presented by smart grids, there may also be a risk when the grids are exposed to malicious acts such as security attacks performed by terrorists. Considering advanced security measures in the design of smart meters could reduce these risks. This paper presents a security study for smart metering systems with a prototype implementation of the user interfaces for future works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security%20design" title="security design">security design</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20meter" title=" smart meter"> smart meter</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20metering%20system" title=" smart metering system"> smart metering system</a> </p> <a href="https://publications.waset.org/abstracts/79129/a-security-study-for-smart-metering-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79129.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">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">416</span> An Application-Driven Procedure for Optimal Signal Digitization of Automotive-Grade Ultrasonic Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Shawki%20Elamir">Mohamed Shawki Elamir</a>, <a href="https://publications.waset.org/abstracts/search?q=Heinrich%20Gotzig"> Heinrich Gotzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Zoellner"> Raoul Zoellner</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Maeder"> Patrick Maeder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, a methodology is presented for identifying the optimal digitization parameters for the analog signal of ultrasonic sensors. These digitization parameters are the resolution of the analog to digital conversion and the sampling rate. This is accomplished through the derivation of characteristic curves based on Fano inequality and the calculation of the mutual information content over a given dataset. The mutual information is calculated between the examples in the dataset and the corresponding variation in the feature that needs to be estimated. The optimal parameters are identified in a manner that ensures optimal estimation performance while preventing inefficiency in using unnecessarily powerful analog to digital converters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analog%20to%20digital%20conversion" title="analog to digital conversion">analog to digital conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=digitization" title=" digitization"> digitization</a>, <a href="https://publications.waset.org/abstracts/search?q=sampling%20rate" title=" sampling rate"> sampling rate</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a> </p> <a href="https://publications.waset.org/abstracts/141040/an-application-driven-procedure-for-optimal-signal-digitization-of-automotive-grade-ultrasonic-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141040.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">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">415</span> Integrated Framework for Establishing Born-Global Firms in Sub-Saharan Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nonso%20Ochinanwata">Nonso Ochinanwata</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Oseloka%20Ezepue"> Patrick Oseloka Ezepue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the process of creating and capturing born-global firm opportunities. It reviews the key constructs that underpin the establishment of born-global firms in sub-Saharan Africa. These include entrepreneurial orientation, resources and capabilities, collaboration, and contextual influences. The paper discusses how individuals and entrepreneurs in sub-Saharan Africa can establish home-based born-global firms that seek early international markets from inception. The paper suggests that sub-Saharan African governments should make a favourable microeconomics policy that will enable entrepreneurs and firms to acquire some certain minimal resources and capabilities, in order to develop global products and services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=born%20global-firms"
