one of the most promising biofuels and able to replace fossil fuels and reduce its different environmental impacts and can be generated from various agroindustrial waste. The Brazil is in first place in bioethanol production to be the largest producer of sugarcane. The bagasse sugarcane (SCB) has lignocellulose which is composed of three major components: cellulose, hemicellulose and lignin. Cellulose is a homopolymer of glucose units connected by glycosidic linkages. Among all species of Penicillium, Penicillium echinulatum has been the focus of attention because they produce high quantities of cellulase and the mutant strain 9A02S1 produces higher enzyme levels compared to the wild. Among the cellulases, the cellobiohydrolases enzymes are the main components of the cellulolytic system of fungi, and are also responsible for most of the potential hydrolytic in enzyme cocktails for the industrial processing of plant biomass and several cellobiohydrolases Penicillium had higher specific activity against cellulose compared to CBH I from Trichoderma reesei. This fact makes it an interesting pattern for higher yields in the enzymatic hydrolysis, and also they are important enzymes in the hydrolysis of crystalline regions of cellulose. Therefore, finding new and more active enzymes become necessary. Meanwhile, β-glycosidases act on soluble substrates and are highly dependent on cellobiohydrolases and endoglucanases action to provide the substrate in the hydrolysis of the biomass, but the cellobiohydrolases and endoglucanases are highly dependent β-glucosidases to maintain efficient hydrolysis. Thus, there is a need to understand the structure-function relationships that govern the catalytic activity of cellulolytic enzymes to elucidate its mechanism of action and optimize its potential as industrial biocatalysts. To evaluate the enzyme β-glucosidase of Penicillium echinulatum (PeBGL1) the gene was synthesized from the assembly sequence from a library in induction conditions and then the PeBGL1 gene was cloned in the vector pPICZαA and transformed into P. pastoris GS115. After processing, the producers of PeBGL1 were analyzed for enzyme activity and protein profile where a band of approximately 100 kDa was viewed. It was also carried out the zymogram. In partial characterization it was determined optimum temperature of 50°C and optimum pH of 6,5. In addition, to increase the secreted recombinant PeBGL1 production by Pichia pastoris, three parameters of P. pastoris culture medium were analysed: methanol, nitrogen source concentrations and the inoculum size. A 23 factorial design was effective in achieving the optimum condition. Altogether, these results point to the potential application of this P. echinulatum β-glucosidase in hydrolysis of cellulose for the production of bioethanol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioethanol" title="bioethanol">bioethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology" title=" biotechnology"> biotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-glucosidase" title=" beta-glucosidase"> beta-glucosidase</a>, <a href="https://publications.waset.org/abstracts/search?q=penicillium%20echinulatum" title=" penicillium echinulatum"> penicillium echinulatum</a> </p> <a href="https://publications.waset.org/abstracts/61890/cloning-and-expression-a-gene-of-v-glucosidase-from-penicillium-echinulatum-in-pichia-pastoris" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61890.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">242</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">285</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">284</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.

The recombinant hemicellulolytic enzymes an endoxylanase (HXYN2), β-xylosidase (HXYLA), and an α-L-arabinofuranosidase (ABF3) were used in hydrolysis tests. These three enzymes are produced by filamentous fungi and were expressed heterologously and produced in Pichia pastoris previously. The aim of this work was to evaluate the effect of recombinant hemicellulolytic enzymes on the enzymatic hydrolysis of sugarcane bagasse (SCB). The interaction between the three recombinant enzymes during SCB pre-treated by steam explosion hydrolysis was performed with different concentrations of HXYN2, HXYLA and ABF3 in different ratios in according to a central composite rotational design (CCRD) 23, including six axial points and six central points, totaling 20 assays. The influence of the factors was assessed by analyzing the main effects and interaction between the factors, calculated using Statistica 8.0 software (StatSoft Inc. Tulsa, OK, USA). The Pareto chart was constructed with this software and showed the values of the Student’s t test for each recombinant enzyme. It was considered as response variable the quantification of reducing sugars by DNS (mg/mL). The Pareto chart showed that the recombinant enzyme ABF3 exerted more significant effect during SCB hydrolysis, with higher concentrations and with the lowest concentration of this enzyme. It was performed analysis of variance according to Fisher method (ANOVA). In ANOVA for the release of reducing sugars (mg/ml) as the variable response, the concentration of ABF3 showed significance during hydrolysis SCB. The result obtained by ANOVA, is in accordance with those presented in the analysis method based on the statistical Student's t (Pareto chart). The degradation of the central chain of xylan by HXYN2 and HXYLA was more strongly influenced by ABF3 action. A model was obtained, and it describes the performance of the interaction of all three enzymes for the release of reducing sugars, and can be used to better explain the results of the statistical analysis. The formulation capable of releasing the higher levels of reducing sugars had the following concentrations: HXYN2 with 600 U/g of substrate, HXYLA with 11.5 U.g-1 and ABF3 with 0.32 U.g-1. In conclusion, the recombinant enzyme that has a more significant effect during SCB hydrolysis was ABF3. It is noteworthy that the xylan present in the SCB is arabinoglucoronoxylan, due to this fact debranching enzymes are important to allow access of enzymes that act on the central chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20design" title="experimental design">experimental design</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrolysis" title=" hydrolysis"> hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=recombinant%20enzymes" title=" recombinant enzymes"> recombinant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20cane%20bagasse" title=" sugar cane bagasse"> sugar cane bagasse</a> </p> <a href="https://publications.waset.org/abstracts/60314/enzymatic-hydrolysis-of-sugar-cane-bagasse-using-recombinant-hemicellulases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60314.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">229</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">281</span> Physicochemical Characteristics and Evaluation of Main Volatile Compounds of Fresh and Dehydrated Mango</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Terezinha%20Santos%20Leite%20Neta">Maria Terezinha Santos Leite Neta</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B4nica%20Silva%20de%20Jesus"> Mônica Silva de Jesus</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannah%20Caroline%20Santos%20Araujo"> Hannah Caroline Santos Araujo</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Donizete%20Dutra%20Sandes"> Rafael Donizete Dutra Sandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Raquel%20Anne%20Ribeiro%20Dos%20Santos"> Raquel Anne Ribeiro Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Narendra%20Narain"> Narendra Narain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mango is one of the most consumed and appreciated fruits in the world, mainly due to its peculiar and characteristic aroma. 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">280</span> On the Rational Roots of the Agnosticism and the Faith</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lola%20Rosalia%20Saavedra%20Guzman">Lola Rosalia Saavedra Guzman</a>, <a href="https://publications.waset.org/abstracts/search?q=Plamen%20Neytchev%20Netchev"> Plamen Neytchev Netchev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In general, agnosticism is perceived as an uncertainty between a well-structured (religious) belief (in some Christian or pagan deity) and its absolute and total absence, often causing the suspicion that an agnostic is an atheist, which is "reinsured" in case if their personal belief is wrong. All of this, along with the prevailing view among the naturalists that science has already demonstrated the inexistence of God, has compelled us to seek the foundation of agnosticism and faith in the contemporary formal human logic, advanced mathematics, and the natural sciences. Along the way, we will find that no natural science can demonstrate the existence of God, nor could it discard it for rational considerations, which show that there is something beyond. After all, it seems that the human intellect is insufficient to respond surely with yes or no to the existence of higher intelligences leaving unconditional faith as the only path to God for Christians and transcendent techniques, for pagan religious beliefs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agnosticism" title="agnosticism">agnosticism</a>, <a href="https://publications.waset.org/abstracts/search?q=formal%20logic" title=" formal logic"> formal logic</a>, <a href="https://publications.waset.org/abstracts/search?q=axioms%20and%20postulates" title=" axioms and postulates"> axioms and postulates</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6del%20theorems" title=" Gödel theorems"> Gödel theorems</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20logical%20faults" title=" and logical faults"> and logical faults</a> </p> <a href="https://publications.waset.org/abstracts/140834/on-the-rational-roots-of-the-agnosticism-and-the-faith" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140834.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">201</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">279</span> A Pervasive System Architecture for Smart Environments in Internet of Things Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Santos">Patrick Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Casal"> João Casal</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20Santos%20Luis%20Varandas"> João Santos Luis Varandas</a>, <a href="https://publications.waset.org/abstracts/search?q=Tiago%20Alves"> Tiago Alves</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Romeiro"> Carlos Romeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%A9rgio%20Louren%C3%A7o"> Sérgio Lourenço</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, 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">278</span> Interoperable Platform for Internet of Things at Home Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Amorim%20Vaz">Fabiano Amorim Vaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Camila%20Gonzaga%20de%20Araujo"> Camila Gonzaga de Araujo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the growing number of personal devices such as smartphones, tablets, smart watches, among others, in addition to recent devices designed for IoT, it is observed that residential environment has potential to generate important information about our daily lives.

To achieve this, we define an architecture capable of supporting the amount of data generated and consumed at a residence and, mainly, the variety of this data presents. We organize it in a particular cloud containing information about robots, recreational vehicles, weather, in addition to data from the house, such as lighting, energy, security, among others.

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">275</span> Relation of Electromyography, Strength and Fatigue During Ramp Isometric Contractions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Ferreira%20Amorim">Cesar Ferreira Amorim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamotsu%20Hirata"> Tamotsu Hirata</a>, <a href="https://publications.waset.org/abstracts/search?q=Runer%20Augusto%20Marson"> Runer Augusto Marson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to determine the effect of strength ramp isometric contraction on changes in surface electromyography (sEMG) signal characteristics of the hamstrings muscles. All measurements were obtained from 20 healthy well trained healthy adults (age 19.5 ± 0.8 yrs, body mass 63.4 ± 1.5 kg, height: 1.65 ± 0.05 m). Subjects had to perform isometric ramp contractions in knee flexion with the force gradually increasing from 0 to 40% of the maximal voluntary contraction (MVC) in a 20s period. The root mean square (RMS) amplitude of sEMG signals obtained from the biceps femoris (caput longum) were calculated at four different strength levels (10, 20, 30, and 40% MVC) from the ramp isometric contractions (5s during the 20s task %MVC). The main results were a more pronounced increase non-linear in sEMG-RMS amplitude for the muscles. The protocol described here may provide a useful index for measuring of strength neuromuscular fatigue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosignal" title="biosignal">biosignal</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20electromyography" title=" surface electromyography"> surface electromyography</a>, <a href="https://publications.waset.org/abstracts/search?q=ramp%20contractions" title=" ramp contractions"> ramp contractions</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/32275/relation-of-electromyography-strength-and-fatigue-during-ramp-isometric-contractions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32275.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">483</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">274</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">168</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">273</span> Times Series Analysis of Depositing in Industrial Design in Brazil between 1996 and 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Pedro%20Fabris">Jonas Pedro Fabris</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberth%20Almeida%20Amorim%20Souza"> Alberth Almeida Amorim Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Emilia%20Camargo"> Maria Emilia Camargo</a>, <a href="https://publications.waset.org/abstracts/search?q=Suzana%20Leit%C3%A3o%20Russo"> Suzana Leitão Russo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the law Nº. 9279, of May 14, 1996, the Brazilian government regulates rights and obligations relating to industrial property considering the economic development of the country as granting patents, trademark registration, registration of industrial designs and other forms of protection copyright.

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">271</span> Decolonialism: Addressing Colonial Legacies and Challenging Dominant Narratives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Amorim%20Da%20Silva">Patricia Amorim Da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the ongoing process of decolonialism, focusing on addressing the lasting consequences of colonialism. Centred on identity within marginalized communities, the study challenges Eurocentric frameworks and advocates for diverse perspectives. Emphasizing critical self-awareness among researchers regarding biases in their work, decolonialism influences feminist theory and global counter-publics. At its core is the concept of epistemicide, the intentional suppression of knowledge in unequal cultural interactions. Colonial imposition has devalued local knowledge, contributing to cultural loss and undermining autonomy. The paper underscores the importance of reclaiming indigenous knowledge to revitalize local cultures and languages, particularly pertinent to the Brazilian context. This contribution to the discourse on decolonialism underscores the imperative to challenge prevailing narratives and empower historically subordinated communities. The study aspires to advance feminist theory and decolonial studies, fostering a more equitable and inclusive global society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decolonialism" title="decolonialism">decolonialism</a>, <a href="https://publications.waset.org/abstracts/search?q=colonial%20legacies" title=" colonial legacies"> colonial legacies</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=Eurocentrism" title=" Eurocentrism"> Eurocentrism</a>, <a href="https://publications.waset.org/abstracts/search?q=epistemicide" title=" epistemicide"> epistemicide</a> </p> <a href="https://publications.waset.org/abstracts/176647/decolonialism-addressing-colonial-legacies-and-challenging-dominant-narratives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176647.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">59</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">270</span> Neural Network Analysis Applied to Risk Prediction of Early Neonatal Death</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20R.%20R.%20Oliveira">Amanda R.

The technology of prevention and intervention in cases of infant deaths is available at low cost and with solid evidence and favorable results, however, with low access cover. Weight is one of the main factors related to death in the neonatal period, so the newborns of low birth weight are a population at high risk of death in the neonatal period, especially early neonatal period. This paper describes the development of a model based in neural network analysis to predict the mortality risk rating in the early neonatal period for newborns of low birth weight to identify the individuals of this population with increased risk of death. The neural network applied was trained with a set of newborns data obtained from Brazilian health system. The resulting network presented great success rate in identifying newborns with high chances of death, which demonstrates the potential for using this tool in an integrated manner to the health system, in order to direct specific actions for improving prognosis of newborns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20birth%20weight" title="low birth weight">low birth weight</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20death%20risk" title=" neonatal death risk"> neonatal death risk</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn" title=" newborn"> newborn</a> </p> <a href="https://publications.waset.org/abstracts/40478/neural-network-analysis-applied-to-risk-prediction-of-early-neonatal-death" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40478.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">448</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">269</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">268</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.

In order to do so, we measured the influence that three different factors external motivational conditionals, educational experience conditionals and personal motivation conditionals exerted over students’ professional identity strength and proposed the measures considering the obtained results. By using hierarchical regression analysis we addressed this issue, across disciplines and bachelor degrees, allowing us to gain also deeper insight into first-year university students PID. Our findings suggest that students’ from the different disciplines are influenced by personal motivational conditionals; while students from sciences are also influenced by external motivational conditionals. Based on the obtained results we propose three different alternative educational and recruitment strategies which aim to increase students’ professional identity strength and reduce the tensions generated during high school-university transitions. From this study theoretical contributions regarding the differences in the influence of these factors on students from different bachelor degrees arise; and practical implications for universities, derived from the proposed strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=professional%20identity" title="professional identity">professional identity</a>, <a href="https://publications.waset.org/abstracts/search?q=transitions" title=" transitions"> transitions</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a> </p> <a href="https://publications.waset.org/abstracts/84330/analyzing-the-factors-that-influence-students-professional-identity-using-hierarchical-regression-analysis-to-ease-higher-education-transition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84330.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">181</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> Engineering Ligand-Free Biodegradable-Based Nanoparticles for Cell Attachment and Growth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simone%20F.%20Medeiros">Simone F.

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">265</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">264</span> Safety and Maternal Anxiety in Mother's and Baby's Sleep: Cross-sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rayanne%20Branco%20Dos%20Santos%20Lima">Rayanne Branco Dos Santos Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Pinheiro%20Barbosa"> Lorena Pinheiro Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Ferreira%20Lima"> Kamila Ferreira Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Manuel%20Tegoma%20Ruiz"> Victor Manuel Tegoma Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Monyka%20Brito%20Lima%20Dos%20Santos"> Monyka Brito Lima Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Wendiane%20Gueiros%20Gaspar"> Maria Wendiane Gueiros Gaspar</a>, <a href="https://publications.waset.org/abstracts/search?q=Luzia%20Camila%20Coelho%20Ferreira"> Luzia Camila Coelho Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Cardozo%20Dos%20Santos%20Brito"> Leandro Cardozo Dos Santos Brito</a>, <a href="https://publications.waset.org/abstracts/search?q=Deyse%20Maria%20Alves%20Rocha"> Deyse Maria Alves Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The lack of regulation of the baby's sleep-wake pattern in the first years of life affects the health of thousands of women. 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">263</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.

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">260</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.

Thus, field research was carried out, with the application of questionnaires, to raise and analyze data related to the topic. Thus, it is believed that Instagram positively influences the dissemination, visibility, reach and profitability of companies in Boqueirão do Piauí. The survey had a low number of companies due to the lack of availability of the owners during the COVID-19 pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Instagram" title="Instagram">Instagram</a>, <a href="https://publications.waset.org/abstracts/search?q=sales" title=" sales"> sales</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion" title=" fashion"> fashion</a>, <a href="https://publications.waset.org/abstracts/search?q=marketing" title=" marketing"> marketing</a> </p> <a href="https://publications.waset.org/abstracts/183163/the-use-of-instagram-as-a-sales-tool-by-small-fashionclothing-businesses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183163.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">57</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> Extraction of Cellulose Nanocrystals from Soy Pods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maycon%20dos%20Santos">Maycon dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Marivane%20Turim%20Koschevic"> Marivane Turim Koschevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Karina%20Sayuri%20Ueda"> Karina Sayuri Ueda</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Lima%20Bertuci"> Marcello Lima Bertuci</a>, <a href="https://publications.waset.org/abstracts/search?q=Farayde%20Matta%20Fackhouri"> Farayde Matta Fackhouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Maria%20Martelli"> Silvia Maria Martelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of cellulose nanocrystals as reinforcing agents in polymer nanocomposites is promising.
