http://ijaers.com/ Open Access international Journal to publish research paper en-us April 2019 Chemical reactions occur between inorganic compounds and wood chips during the cooking step of the Kraft process. White liquor, which in this process is composed of sodium hydroxide (NaOH) and sodium sulfide (Na2S), is mixed with wood chips in the digester in order to dissolve the lignin and produce wood pulp. However, other compounds are formed during the course of the chemical reactions. These compounds are volatile and malodorous due to the combination of the sulfur in white liquor and the carbon chains in lignin. This combination creates total reduced sulfur (TRS) compounds, which are malodorous gases responsible for the distinctive odor of the Kraft pulping process. This paper discusses the chemical composition of the wood species that contribute to these gas emissions. Gases are also released in other stages of the process, e.g., from the woodchips stored in the woodyard for factories that use only long pine fiber, from the digester, pulp washing filters, and from white, black and green liquor storage tanks. One way to reduce TRS emissions is through continuous attention to and correction of the pH levels of liquors containing sulfide ions. http://ijaers.com/detail/influence-of-the-chemical-properties-of-wood-on-the-odor-produced-by-the-kraft-pulping-process/ Bruno de Oliveira Chagas, Thomas Ricardo Wolski, Osvaldo Vieira http://ijaers.com/uploads/issue_files/1-IJAERS-MAR-2019-50-Influenceof.pdf Governance relies on a set of principles, rules and procedures that stakeholders (the ones interested in the results and performance of the organization) establish to optimize the management of organizations. It was developed a research of applied nature and quantitative approach, where bibliographical procedures and surveys were used to reach the descriptive goals. The proposal was developed, in the first stage, by constructing a theoretical framework on governance based on literature and based on institutional documents and regulations. It has been found that Disclosure is an obligation to inform or give transparency of the product of strategies, policies and processes, Accountability is essential in mandatory reports and also as an instrument of transparency of acts spontaneously, and Compliance, that states that managers must ensure for the sustainability of organizations, through the goal of sustainability. The research findings reflect a disturbing reality regarding the involvement of managers in regard of the importance of the information to extractivists, as well as the qualitative nature of the information provided by the institutions. In the observation, the highlighted concept was accountability. http://ijaers.com/detail/the-perception-of-leaderships-on-governance-in-the-extractive-reserves-of-the-state-of-rond-nia/ Gleimiria Batista da Costa, Bruna Lívia Timbó de Araújo Balthazar, Nilda dos Santos, Jackson Balthazar de Arruda Câmara, Aline Maiara da Silva Lima, Rosalina Alves Nantes http://ijaers.com/uploads/issue_files/2-IJAERS-MAR-2019-56-ThePerception.pdf The literature on Workplace Safety Culture (WSC) has evolved in the conceptual dimension in a movement away from technical aspects toward more human aspects, but remains incipient regarding the creation of measurement instruments and quantitative evaluation with a totality of technological, organisational and human factors.To fill this gap, this article presents and validades the Workplace Safety Culture Model (WSCM) applied in a survey, with a total of 1196 operational employees of six factories, frommetallurgical sector. To validate the WSCM, the statistical procedure Exploratory Factor Analysis (EFA) was used to reduce the set of variables to a lower number of factors to characterize the attribute dimensions of the object in question. The results presents a reduced version of the proposed model, distributed in ten factors: Leadership, Commitment, Pressure at Work, Infrastructure, Learning, Efficiency, Management System, Feedback, Responsibility,and Communication.The results of the EFA produced a factor structure with relatively higher loads on the appropriate factors. The WSCMoffers us a robust tool to analyze an organization's WSC maturity. For the methodological improvement of the model, we suggest future research with diverse cultural contexts. http://ijaers.com/detail/workplace-safety-culture-model-wscm-presentation-and-validation/ Patrícia Amélia Tomei, Giuseppe Maria Russo http://ijaers.com/uploads/issue_files/3-IJAERS-MAR-2019-49-WorkplaceSafety.pdf In the present context, geopolymer appears as an ecologically viable alternative compared to Portland cement, due to lower CO2 emissions rate. The objective of this work is to study reinforced geopolymer pastes with elongated sisal fibers by means of parameters such as flexural strength. For this, metakaolinwas used as an aluminosilicate source material in addition to a combination of sodium silicate and sodium hydroxide as the activator solution. The influence of the independent variables sisal fiber percentage, molar ratio between activator and metakaolin, and the curing time was evaluated through an experimental design. The statistical model of central composite planning was used to optimize the results obtained. The best value for the modulus of rupture was of approximately 9.3 MPa, obtained with 2 days curing, with the activator/metakaolin ratio of 0.59 and percentage of sisal fiber de 4.34. http://ijaers.com/detail/optimization-of-metakaolin-based-geopolymer-composite-using-sisal-fibers-response-surface-methodology-and-canonical-analysis/ Lorayne Cristina Silva, Rondinele Alberto dos Reis Ferreira, Leila Aparecida de Castro Motta, Lucas Bellini Machado http://ijaers.com/uploads/issue_files/4-IJAERS-MAR-2019-55-Optimizationof.pdf In this work the influence of the addition of the variables cellulose kraft pulps, natural rubber latex and metakaolin as reinforcements in cementitious composites was studied.The influence of the analyzed variables on the properties of the cementitious composites was evaluated through an experimental design (DOE) at 28 days age. The best modulus of rupture was the 12.29 MPa presented by the composite with 7.097% cellulose, 0.37% latex and 50.155% metakaolin. The composite with 5.928% cellulose, 1.85% latex, and 55.195% metakaolin had the best toughness of approximately 1.10 kJ/m². According to the results obtained contact angle, it was possible to prove that the latex adhered to the pulp, hydrophobizing it. Therefore, it was concluded that it is possible to use the natural rubber latex in the cellulosic pulp and the metakaolin to protect the fiber in cementitious composites. http://ijaers.com/detail/optimization-of-the-percentage-of-cellulose-latex-and-metakaolin-in-the-production-of-cementitious-composites/ Lara Cristina Péres dos Santos, Rondinele Alberto dos Reis Ferreira, Leila Aparecida de Castro Motta, Daniel Pasquini http://ijaers.com/uploads/issue_files/5-IJAERS-MAR-2019-54-Optimization.pdf Pasture production is estimated through remote sensing techniques with the aid of models and algorithms. The application with no need for extensive field measurements is one of the advantages of the Surface Energy Balance Algorithm for Land (SEBAL). The objective of this work was to estimate energy fluxes and, subsequently, pasture biomass with the aid of remote sensing techniques. The study area is located on the Experimental Farm of Embrapa Beef Cattle, municipality of Campo Grande, State of Mato Grosso do Sul, Brazil. For the implementation of the SEBAL and estimation of energy fluxes and biomass of the pasture areas, meteorological data and Landsat 5 - TM image were used. It was found that the technique has the potential to be applied to indicate the forage availability and to support decision-making in the planning and management of the extensive production of beef and milk cattle, with economic and environmental sustainability of pasture areas. http://ijaers.com/detail/estimation-of-energy-flux-and-biomass-in-pasture-areas-through-remote-sensing-techniques/ Ricardo Guimarães Andrade, Marcos Cicarini Hott, Walter Coelho Pereira Magalhães Junior http://ijaers.com/uploads/issue_files/6-IJAERS-MAR-2019-52-Estimation.pdf Basic sanitation, consisting of water supply, sanitary sewage, stormwater drainage and solid waste management, is fundamental for the quality of life of the population, reduction of public health expenditures, as well as contributing to the attraction of investments. In Brazil, the progress of these services to reach the goal of universalization is modest and Porto Velho, capital of Rondônia and located in the Brazilian Amazon, is against this advance. Its indicators show that among the 100 largest Brazilian cities in terms of population (including all capitals), its ranking of sanitation is the worst of all. This paper presents several data on sanitation in Porto Velho, comparing the evolution of its sanitation ranking and its Gross Domestic Product (GDP) ranking from 2003 to 2016, the consequences of the deficiency of these services and analyzes of current investments compared to the goals established for the universalization of sanitation in the municipality. Driven in recent years, mainly by the construction of two large hydropower plants, the population and its GDP grew, but sanitation did not follow this evolution as it should. The conclusion was that there are several problems due to the deficiency of sanitation in the city and the investments planned will not be enough to reach the goal of universalization, needing to raise more resources and prioritize the effective execution of the works contracted. http://ijaers.com/detail/basic-sanitation-in-porto-velho-the-worst-brazilian-capital-in-this-area/ Kleber Lúcio Borges http://ijaers.com/uploads/issue_files/7-IJAERS-APR-2019-9-BasicSanitation.pdf The aim of this work was to accomplish an investigation post-treatment in Cynoscionstriatus fillets, using different concentrations of sodium tripolyphosphate and blends containing sodium tripolyphosphate and sodium chloride, and evaluate the weight of loss and their influence on the content of total protein, moisture and phosphate. Samples underwent four treatments: sodium tripolyphosphate solutions (TPFS) 2% and 10% and blends containing sodium tripolyphosphate with sodium chloride (NaCl) 2% and 10%. 148 fillets were immersed in each treatment for 2 hours and weighted individually at three moments: prior to immersion, post-immersion and post-defrosting. Gravimeter results showed weight gain in all treatments (p>0.05). When TPFS 2% (0.28%) and blend 2% (8.38%) were compared, samples immersed in Na5P3O10 revealed a weight gain (p>0.01). In treatments TPFS 10% (12.48%) and blend 10% (9.19%), the samples with only TPFS had weight increase (p>0.01). Solution with TPFS 10% within the context of the four treatments had the greatest weight in immersion (12.48%) and the lowest loss of water in defrosting (3.72%). Physical and chemical analyses for moisture, total proteins and phosphate had differences in weight for the four treatments (p>0.01), with the exception of the treatments blend 2% and blend 10%. The four treatments did not exceed the standard established by the Ministry of Agriculture (until 0.5% TPFS for every 100 g of fillet). http://ijaers.com/detail/physical-and-chemical-analysis-of-cynoscionstriatus-fillets-immersed-under-different-saline-concentration/ Victor Goulart Pires, Cleonice Gonçalves da Rosa, William Gustavo Sganzerla, Michael Ramos Nunes, Matheus Vinícius de O.

The joints angles define the behavior of a segment in relation to another and, consequently, the overload on the tissues. The hip joint centre (HJC), regression equations system based on pelvic anatomy, is a parameter frequently used as reference point to determinate the hip and knee angles, therefore, is considered in the literature as an important factor in the kinemactics analysis of the human gait. Two analytical methods are recognized in the HJC estimation, the predictive method uses the difference between the anatomical points of the human body in the data collect, and the functional method uses a sphere adjustment approach. In the present research, it was used kinemactics data from seven volunteers, collected by Qualisys® system on a treadmill, and through algorithms developed in MATLAB®, the HJC were estimated by two predictive method systems (Bell and Davis) and one system of the functional method (with sphere adjustment approach based on the StarArc movement) and the joints angles which describes the flexion/extension movement of the hip and the knee were determined. Finally, a study was carried out on the influence of the methods for HJC estimation in the determination of hip and knee joints angles. The errors presented in the HJC estimated by the three methods were documented, but did not present significant influence in the values found by the angles of the joints. http://ijaers.com/detail/analysis-of-the-method-for-estimating-the-hip-joint-centre-for-determination-of-the-hip-and-knee-joint-angles/ Jordana S.R.

A time series of fishery production of more than 30 years of Tucuruí Hydroeletric dam, between 1981 and 2016, in low Tocantins, in ten landing harbor (five upstream and five downstream) was analyzed to compare productivity and indicate suggestions for better planning and public policies focused on the fishery resources in this basin. After analyzing over 16,000 landing data, CPUE (kg / day) indicated that after an exponential growth upstream in the first 15 years of the dam, there was a decline trend in fish stocks up to 2016, mainly upstream. The biodiversity of the ichthyofauna was higher downstream and Mapará H. marginatus was the main species captured. It is concluded that the maintenance and accessibility by society of a program to monitoring landings in the region, as well as studies of population dynamics in order to better plan the fishing effort, is fundamental. It should also be emphasized that environmental education should focus on the involvement of fishing communities, alerting public managers about the importance of knowledge about productivity and that the decline trend of upstream stocks should be considered in the formulation or incentive of policies aimed at development of artisanal fisheries on Tocantins-Araguaia basin. http://ijaers.com/detail/the-fishing-productivity-assessement-upstream-and-downstream-of-tucuru-hydroeletric-dam-tocantins-araguaia-basin-brazil/ Adriano Prysthon, Cristiane Vieira da Cunha, Carolyne, R.G.Dias http://ijaers.com/uploads/issue_files/10-IJAERS-MAR-2019-44-TheFishing.pdf This paper presents an analysis of the impacts of decentralized production on electrical distribution grids. The impact on power flow and the impact on the values of currents in case of the fault are presented. The study has been applied to the IEEE 9 bus for testing the effects of the distributed generator connected to the distribution grid. Four default types are simulated in order to obtain sure results; also different scenarios are varied to show the influence of the power injected by distributed generator DG and the influence of the fault location according to DG. The presented results show that the short-circuit current increased at the injection points of DG and the direction of the power flow became bidirectional if the injected power is greatest. http://ijaers.com/detail/analysis-of-the-impacts-of-decentralized-production-on-distribution-grids/ Zineb El Idrissi, Faissal Elmariami, Touria Haidi, Abdelaziz Belfqih, Jamal Boukherouaa http://ijaers.com/uploads/issue_files/11-IJAERS-MAR-2019-53-Analysisof.pdf This paper aims to demonstrate a business model and management for a virtual collaborative news environment (VNCE), which is being implemented at the Northern Fluminense State University - UENF, in the Postgraduate Program in Cognition and Language. The difficulty of the journalistic business in surviving, in view of technological changes, the growth of the digital environment, the predominance of intangible wealth, the valorization of intellectual capital, among other variables, has raised the question of the real possibility of a journalistic organization surviving in this scenario. Interdisciplinary environment involves research in the area of communication, information system, administration and accounting and seeks to meet the demands of generation, storage, retrieval, processing and transmission of information in this digital era. An increasingly intelligent, collaborative environment with the active participation of all the agents involved, that is, with the total interaction of the reader-user of the internet. A business and management model that has as main differential the recognition of the intangible wealth, besides the traditional tangible gains, in an era of new economy, where the digital business prevails and the primacy of the intangible wealth, recognized in the expectation of future gains of these companies. Governed by the logical intelligence of a control system whose purpose is the congruence of objectives of the agents that form the business, able to measure the contribution of each agent, generating their respective monetary recognition. Through a cyclical process of creation, delivery and capture of value by all the agents involved that allows planning, control, feedback and replanning, the proposed model is supported by a goal congruence control system that will enable management of this environment, ensuring its continuity and expansion of scope. http://ijaers.com/detail/business-and-virtual-collaborative-news-model/ Daniele Fernandes Rodrigues, Carlos Henrique Medeiros de Souza, Luiz Renato de Souza Justiniano, Gabriel Moreira, Ariel Adorno de Sousa, Izan Fabrício Neves Calderaro, Fabrício Moraes de Almeida http://ijaers.com/uploads/issue_files/12-IJAERS-MAR-2019-59-Businessand.pdf The present study was aimed to develop a diagnosis model to evaluate the organization before the implementation of a family succession planning.

A new meaning is assigned to the usual Schwarzschild-Like solutions (Hilbert, Droste, Brillouin, Schwarzschild), as well as to the very concepts of “black hole” and “event horizon”. We hypothesize a closed Universe, homogeneous and isotropic, characterized by a further spatial dimension. Although the Universe is postulated as belonging to the so-called oscillatory class (in detail, we consider a simple-harmonically oscillating Universe), the metric variation of distances is not thought to be a real phenomenon (otherwise, we would not be able to derive any static solution): on this subject, the cosmological redshift is regarded as being caused by a variation over time of the Planck “constant”. Time is considered as being absolute. The influence of matter/energy on space is analysed by the superposition of three three-dimensional scenarios. A short section is dedicated to the so-called gravitational redshift which, once having imposed the conservation of energy, may be ascribable to a local variability of the Planck “constant”. http://ijaers.com/detail/black-holes-a-different-perspective/ Carmine Cataldo http://ijaers.com/uploads/issue_files/14-IJAERS-APR-2019-13-BlackHoles.pdf Currently the theme Shelf Life appears as a large tool to increase the quality and control of life time.

The main principal of this Shelf Life system is an auxiliary tool for verifying data search processes and a search for better results, including a computational tool with extensive performance analysis. The method used consisted, first of all, of the process of obtaining real data on the receipt and indebtedness of companies, thus creating a virtual planning and planning environment.

To characterize the winemaker's decision-making in the management of the vineyard cultivation system, the procedures were: analysis of the selection criteria of the managers before the conventional and biodynamic systems of vinifera cultivation, considering the questions of opportunity costs of production as criterion evaluation of alternatives. It is an exploratory and descriptive study which contains both qualitative and quantitative analysis, from an intentional sample, for convenience and non-probabilistic. It has been discovered that vineyard management is a complex task, which requires information, technical follow-up, and farmers who are willing to realize that production alternatives go beyond the boundaries of the property's gateway. Finally, it was evidenced that management requires the commitment of all the factors, which are part of the productive chain, so the whole production system can remain competitive and attentive to the different opportunities that using the soil can provide. http://ijaers.com/detail/decision-making-in-the-management-of-vineyards-cultivation-systems/ Cláudia Brazil MARQUES, João Armando DESSIMON, kelly Lissandra BRUCH , Carlos HONORATO Schuch Santos, Fabrício Moraes de ALMEIDA http://ijaers.com/uploads/issue_files/25-IJAERS-APR-2019-23-DecisionMaking.pdf The aim of the present study is to analyze the use of the artificial intelligence Bot and its relation to business benefits, with emphasis on understanding acceptance and use factors based on clients’ perspectives.

The increase in the publication of works on applications of organotin compounds containing organic ligands is a milestone in the development of chemical organoestânic as possible research and the discovery of complex, especially in medicine. Brazil has excelled in the production of cheese, however many contamination has hindered the development of cheese with qualities, this fact affects mainly small farmers and family farming. This study aimed to evaluate the potential inhibition of mycelial average growth of fungi Penicillium brevicompactum, Penicillium camembert, Penicillium comunne, Penicillium expansum and Penicillium solitum, collected in a cheese ripening chamber dairy from UFLA – Universidad Federal of Lavras a)α-hydroxycarboxylic acid (DL-mandelic acid, benzylic acid, dl-4-bromomandelic acids acid, dl-4-methoxymandelic acid and dL-2-chloromandelic acid) at concentrations of 1 and 50 ppm; b) with trimethyltin chloride in concentrations of 1 and 50 ppm; c) the complexes derived from the reactions of α-hydroxycarboxylic acids listed reacted with trimethyltin ([Me2SnMand] [Me2SnBenz2] [Me2SnBrm2] [Me2SnMeo] and [Me2SnClm2]) at concentrations of 1, 5, 10 and 50 ppm. The compound inhibited triorganoestânic generally, the mean mycelial fungal growth in concentrations of 1 and 50 ppm. With respect to the complex, It observed that the [Me2SnClm2] showed the highest overall mean percentage inhibition (90.0%), while the complex [Me2SnBrm2] showed the lowest average (57.3%). The inhibitory percentage was calculated on the overall average concentration of 50 ppm and fungi that have suffered greater inhibition were Penicillium commune and Penicillium solitum. These compounds showed excellent results in the inhibition of fungi that infect cheese ripening cameras, and can be an alternative to the social improvement of Brazil, as its low cost allows small producers to make use of this technology, it is expected that this work can be the first step towards a revolution in this segment and that further research be promoted from this work.

Moreover, the highest cost for raising these animals is pet feed, which should be served at appropriate times and quantities. In contrast, the daily lives of pet breeders have often unforeseen events such as meetings, last minute trips, traffic jams, among others. With the purpose of helping the difficulties faced by small domestic animal breeders, this work presents the implementation of a solution called RobotChow, capable of serving granulated feed and water exchange at pre-scheduled times and volumes for pets; in such a way that the user can monitor if the animal is feeding. For this, the customer can use instant messaging on the mobile, with a solution interface that controls the features only interacting ("chatting") with the application. In addition to providing commands, the solution also send photos or even notify the user if something is unusual to happen with the pet. The user can monitor his/her pet regardless of space-time, just accessing the internet. The entire solution was developed in Raspberry pi, using Python, and it is integrated with the Watson Assistent and Telegram cloud services. http://ijaers.com/detail/robot-chow-automatic-animal-feeding-with-intelligent-interface-to-monitor-pets/ Rogerio Nogueira, Humberto Araújo, David Prata http://ijaers.com/uploads/issue_files/30-IJAERS-APR-2019-19-RobotChow.pdf In this study, the performance, emission and combustion characteristics of two different biodiesel blends produced from Mahua and pongamia methyl esters were compared with conventional diesel fuel. Methyl esters for experiment were produced by using a catalytic transesterification process and, compared the properties with ASTM standard values of biodiesel fuel and diesel fuel. The experiments were performed in a four stroke, single cylinder, common rail direct injection (CRDI) system assisted diesel engine at a constant speed of 1500rpm with varying injection pressure. During the tests, the specific fuel consumption, brake thermal efficiency, combustion and exhaust emissions of the CRDI diesel engine were measured. From the results it is clear that the HC, CO and smoke levels are drastically reduced when using the methyl ester blends. Especially in the case of MME20, NOx emissions was minimum when compared with other blends and it also found less amount of other harmful emissions like HC, CO and smoke. http://ijaers.com/detail/reduction-of-emissions-from-common-rail-diesel-engine-using-mahua-and-pongamia-methyl-esters/ C.

The objective of this study was to assess the origin and branching of the phrenic nerve in 27 swine (Sus scrofa domesticus – Linnaeus, 1758) fetuses of the Pen Ar Lan line—19 males and 8 females. They were dissected after fixing in a 10% formaldehyde solution. The phrenic nerve originated from 51 (94.4%) antimeres of the fifth cervical spinal nerve (C5), 54 (100%) antimeres of the sixth cervical spinal nerve (C6), and six (11.11%) antimeres of the seventh cervical spinal nerve (C7). Considering this distribution, the phrenic nerve emitted fibers to the pericardium and branched into the diaphragm muscle in all specimens evaluated. Six different branching were found, most frequently in the dorsal, lateral, and ventral branches in 22 (40.74%) antimeres, followed by branching to dorsal branches and ventrolateral trunk in 18 antimeres (33.33%). In addition, two of the branching found are not cited in scientific literature, denoting their variability. The dorsal branches were distributed to the pillar muscles in the lumbar part, the ventral branches to the sternal part, and the lateral branches to the dorsal part. http://ijaers.com/detail/origin-and-branching-of-the-phrenic-nerve-sus-scrofa-domesticus-linnaeus-1758-of-the-pen-ar-lan-line/ Lázaro Antônio dos Santos, Frederico Lizardo Balbino, Lorena Tannus Menezes-Reis, Igor Bernardes Rodrigues, Paulo Antônio Moreira Santos Lemos Rezende, Abelardo Moreira dos Santos Penna-Neto, Lucas Assis Ribeiro, Frederico Ozanam Carneiro e Silva http://ijaers.com/uploads/issue_files/34-IJAERS-APR-2019-20-Originand.pdf A major problem with using relational databases, is writing efficient SQL queries.

With the high participation of the renewable energy resources, the system is considered to be highly advantageous. But, with such integration comes the problem related to their uncertain nature. The major source of energy in the microgrid is considered to be the solar PV which depends upon the value of solar irradiance i.e. uncertain in nature. This uncertainty is dependent upon the various weather based parameters like temperature, wind speed, rain etc. Along with the uncertain source, the load in the system is also variable in nature; depending upon the similar weather based parameters. Thus in this paper, using the high order multi input multi output (MIMO) fuzzy logic approach the forecasting of both the solar irradiance and electric load has been done. The proposed approach is validated by comparing with the real time values of the parameters. http://ijaers.com/detail/electric-load-and-solar-irradiance-forecasting-in-microgrid-using-high-order-mimo-fuzzy-logic-approach/ Gurpreet kaur, Manpreet Singh http://ijaers.com/uploads/issue_files/39-IJAERS-APR-2019-37-ElectricLoad.pdf During the process of choosing a new product, the selection of those that are financially viable and economically profitable is crucial. It is essential to consider as important all the elements that influence the cost of a product. At this point of feasibility analysis, the role of process engineering is to analyze the manufacturing process and to predict, with maximum precision, the time required to manufacture a given product, since the manufacturing time directly influences the value of direct labor cost. The purpose of this research is to use MOST (Maynard Operations Sequence Technique), from Predetermined Motion Time System, to estimate the time required to manufacture a new product. This work, classified as an exploratory case study with qualitative and quantitative analyzes, was developed in a multinational industry of the audio sector located in the Manaus Industrial Pole. The analysis of the new product using image and/or sample served as the basis for the choice of assembly sequence, the first step to be developed for the use of MOST. Afterwards, the indices were applied for each activity performed during the manufacturing and finally the standard time of assembly of the product was calculated. The result of this research shows that through MOST it was possible to estimate the standard time of a new product and obtain the labor cost of R$1.82. http://ijaers.com/detail/most-as-a-tool-to-support-the-deployment-of-new-manufacturing-products/ Natália Figueredo da Silva, Jandecy Cabral Leite http://ijaers.com/uploads/issue_files/40-IJAERS-APR-2019-43-MOST.pdf The search for recreational activities is letting the bathers vulnerable to possible contamination in the bathing places, generated by waste from the sewage, accumulation of waste, pollutants present in the atmosphere, pesticides used in plantations that somehow reach the riverbeds, among several others that end up causing, for the most part, the emergence of bacteria such as total coliforms and Escherichia coli (E. coli).

The evaluation of the groundwater table occurred in the water of cacimbas wells or Amazonian wells with an average depth of 10 meters in the city of Nova Mamoré, in the State of Rondônia, located in the southern region of Western Amazonia bordering the Republic of Bolivia. METHODS: Eighty (80) water samples were collected in the city's urban center, defined and evaluated for nitrate (NO3-) in a proportion above or below the values defined by Ministry of Health Ordinance No. 2.914/2011, which governs standards of water standardization and potability in Brazil. From the data obtained, maps with georeferenced information were made to locate the areas with the highest and lowest contamination potential. The use of geostatistics assisted in the accomplishment of the spatialization of the samples and in the analysis of the spatial patterns allowing a higher quality of the generated data. Results: Sixty-two and a half percent (62.5%) of the samples presented nitrate levels above 10 mg/L, making it unfit for human consumption. Conclusions: This study indicated that the source of the contamination originates from the result of anthropogenic activities, evidenced by the inefficiency of the sanitary sewage system, one of the basic sanitation axes in which, specifically, it addresses the collection, treatment and adequate disposal of sanitary sewage and other hygiene practices.

In the earlier system of transactions all the nodes in the network are connected using centralized approach in which a node act as a server and all other nodes are connected to it. It is similar to client server model. All the information are stored in the centralized node. When the centralized node is been hacked by the hacker then it provides entire details about the transaction and doesn’t provide enough security. Since the privacy of these data is very less we proposed to have more secured system. The proposed system uses a decentralized network that doesn’t rely on a central point of control. A lack of a single authority makes the system fairer and considerably more secure using block chain and multi signature. A block chain is a public ledger of information collected through a network that sits on top of the internet. It is how this information is recorded that gives block chain its ground breaking potential and it is extremely important that the information being stored is honest and accurate. The main aim of this system is to provide transaction security without using a trusted third party since it reviews all the critical transaction communications between the parties, based on the ease of creating fraudulent digital content.

For this, the present work aimed to produce aerobic granules in mesophilic conditions and, after their stability, leads them to thermophilic conditions. After the thermophilic granules were obtained, analyzes of their maintenance, treatment efficiency and verification of the production of the extracellular polymeric substances (carbohydrates, proteins and humic acids), present in the granules under these conditions were carried out. It was observed that the granules, generated from the biological sludge and the effluent of a pulp and paper industry, can act up to a temperature of 45 ºC, presenting a removal rate of around 70%, without great loss of efficiency of the proposed treatment compared to that of mesophilic flocculent sludge. http://ijaers.com/detail/treatment-of-effluent-of-the-cellulose-and-paper-industry-using-aerobic-granular-sludge-thermophilic/ Natalino Perovano Filho, João Carlos Teixeira Dias, Claudio Mudadu Silva, Rachel Passos Rezende http://ijaers.com/uploads/issue_files/49-IJAERS-APR-2019-32-Treatmentof.pdf This article is the result of a master’s thesis and has a general objective to know the actions and care practices carried out by the psychosocial program CAPS AD III-Gurupi/TO, with the families of users of alcohol and other drugs.

Through the analysis of data and results, it was possible to identify the points that make working with families difficult. The research found in the work of the CAPS, greater emphasis on harm reduction and medicalization, little emphasis on social reintegration. Thus, it is concluded that the CAPS ADIII-Gurupi presents relevant aspects in the accomplishment of the work as the commitment of the multi-professional team, the adequate physical space and the professional qualification. http://ijaers.com/detail/public-policies-with-users-of-alcohol-and-other-drugs-in-caps-ad-iii-in-gurupi-to/ Dulcimara Carvalho Moraes, Marcelo De Souza Cleto http://ijaers.com/uploads/issue_files/50-IJAERS-APR-2019-35-PublicPolicies.pdf In order to evaluate children’s oral health related to frequency in a public program of dental attention early, this research conducted a study retrospective cohort which reached 252 assessment children, between 36 and 60 months of age, in the city of Gurupi, Legal Amazon region, Brazil. Three groups of children were analyzed: G1: effective participants of the program since birth; G2: children no longer participate for more than 24 months of the program, and a control group G3: children who never participated in prevention project. The evaluation was conducted in two stages: interview mothers and clinical examination in children for analysis of caries, gingivitis, and malocclusion. The index of caries in deciduous teeth (dmft) presented different data between groups G1 = 0.05, G2 = 1.96 and G3 was 3.30. Oral diseases were statistically more common in children who have never attended an oral health program (p = 0.025). The main reason cited by 54% of mothers who have left the program, was the oblivion of the scheduled day. Thus, children who effectively attended the oral health program showed the best results in relation to caries, gingivitis, and malocclusion, when compared to those who have left or have never participated. http://ijaers.com/detail/children-s-evasion-in-a-public-program-of-early-dental-attention/ Rise Consolação Iuata Costa Rank, Joana Estela Rezende Vilela, Marcos Sampaio Rank, Omar Franklin Molina, Wataro Nelson Ogawa http://ijaers.com/uploads/issue_files/51-IJAERS-APR-2019-39-Children.pdf New designs and styles of attire such as coats, hats, and masks, colored and with prints are emerging in the market and offered to healthcare professionals, and in many situations, the justification is aimed at minimizing the stress caused by the white coat and optimizing the child dental treatment. To Verify the preference and perception of schoolchildren in relation to the new color patterns of dental attire. Transversal Descriptive study, Quality Quantitative Approved by the Research Ethics Committee of Human Beings. The sample consisted of 748 students of both sexes, aged randomly selected in public and private schools in the city of Gurupi, in the State of Tocantins, Northern Brazil. The Study was conducted with an interview and test to schoolchildren. The children of public schools (50%) and private (46%) they preferred the traditional white coat and the most rejected was printed/colored coat. In the hat and mask the groups among schoolchildren presented a statistical difference for preference (p > 0.05). The mask rejected by children from private schools (70%) and public (84%) for being "ugly" was with an animal mouth. Children prefer the white color of coats, hats and masks, showing the selection by the traditional pattern, considering what would be "right" in their vision. http://ijaers.com/detail/preferences-and-perceptions-of-school-children-in-relation-to-new-styles-and-colors-of-dental-attire/ Rise Consolação Iuata Costa Rank, Joana Estela Rezende Vilela, Lorena Pereira Vieira, Morgana Aguiar Gomes, Wataro Nelson Ogawa http://ijaers.com/uploads/issue_files/52-IJAERS-APR-2019-42-Preferences.pdf
