Study of the Technical Feasibility of the Usage of Waste from Electric Posts as Coarse Aggregate in the Mixture of Concrete for Structural Purposes

This work aims to analyze the technical and economic feasibility of using concrete post waste as coarse aggregate for the manufacture of new electricity posts. In order to carry out the experimental study, waste processing, characterization and finally concrete dosage were carried out. The adopted methodology consists in the partial substitution of the natural aggregate by recycled aggregate originated from damaged concrete electricity posts collected in the city of Palmas - TO. In order to obtain the results, specimens and new concrete posts were tested with the replacement of the aggregate, respecting the approval guidelines for concrete post for electric power networks. The results obtained point to the use of waste from unusable posts as a potential alternative in removing the residue from the environment, replacing natural aggregates in the manufacture of new posts that meet the mechanical resistance specifications.

Coastal regionalization with self-organizing maps-Water quality variables applied to cluster formation

Human sewage disposal can interfere with water quality and thus diminish the ecosystem services provision, including Phytoplankton lifespan. Understanding the role played by sewage disposal in water quality can be useful not only for tourism planning but also for characterizing beaches based on water quality using secondary data and avoiding the costs of sampling and monitoring. The objectives of this paper were to understand the water quality behavior at several small bays in a coastal city of Brazil and to test the use of self-organizing maps in forming clusters similar to those derived from geomorphology and to understand how representative these maps were of the water quality of the whole city. According to our results, self-organizing maps showed similar behavior to geomorphological processes, confirm the hypothesis of cluster formation due to quality and also presented a new pattern of data variation related to seasonality that was not noticed before in the sampling.

Geographical Indication and Centrality: A Hypothesis test in the Northeastern Region of Brazil

Geographical Indications (GIs) refer to products and services with unique characteristics of a given region, granting a certain level of excellence to these goods and services. Moreover, GIs are connected to the locations, in recognition of their territoriality, as well as to the regionâ€™s cultural and historical identity, being attached to the level of centrality of the region and promoting greater trust, as centrality is directly linked to its catchment area. In this regard, the present work is aimed at carrying out a temporal comparison of the centrality indices of the five groups of Geographical Indications in Northeastern Brazil between the years of 2006 and 2017, in order to test the hypothesis established, determining whether such event is enough to explain the influence of the products and goods on their respective cities of origin. This is a quality-quantitative research, based on a bibliographic and documentary survey by analyzing five GI groups from the Northeastern region of Brazil, focused on their relative share of the Gross Domestic Product of private services in certain municipalities and taking into account five higher-order spatial cutouts: microregion, mesoregion, state, region and country. Besides determining the centrality indices, carried out using the well-known Principal Component Analysis (PCA), the Analysis of Variance (ANOVA) was also applied. The results of the present research did not identify any indications that granting GIs is enough to promote a distinct level of development to the municipalities. Therefore, GIs did not exhibit any relevant effect on the municipal levels of centrality

Rick Carneiro de Menezes, Aline Castro Jansen

The pandemic outbreak of COVID-19 triggered a profound economic crisis of global proportions, due to measures to contain the transmission of the virus causing the disease, being social isolation and, in more severe situations, the complete closure of non-essential activities (lockdown). In order to survive this scenario, many organizations began to adopt remote work as an alternative to continue their activities. However, this new way of working could not be properly structured and planned due to the urgency of such adaptation. Thus, the aim of this study is to discuss the advantages and challenges of the home office emergence due to the pandemic outbreak of Coronavirus. Among the main benefits are the flexibility and digital learning of professionals, and the technological transformation of organizations. The prominent limitations were the lack of infrastructure, the extension of the working day and the tenuous limit between professional and personal life.

Non-parametric Inference Applied to Damage Detection in the Electromechanical Impedance-based Health Monitoring

The electromechanical impedance-based structural health monitoring is a non-traditional vibration technique that compares a pristine signature to a damaged one. However, in order to compare a complete frequency response function to another, it is necessary to create a virtual index called damage metric, which indicates how far the investigated structure states from the initial condition. The most used index is the RMSD (Root Mean Square Deviation) to have a quantitative measurement of the monitored structures but CCD (Correlation Coefficient Deviation) is more robust to temperature changes. Thus, this contribution focuses on thisCCD damage metric for simulated damages (mass addition) of Al beams in a 2x5 factorial design. The first factor considered was the pristine or damage condition. The second factor was the environmental temperature of the specimen, during the signature gathering, for five levels: -10 oC, 0 oC, 10 oC, 20 oC and 30 oC. According to the references, temperature is a very important aspect to be considered because some changes in the signature can be promoted, and for this purpose a temperature chamber was used in the study. Several statistical evaluations were performed and this contribution illustrates the median of the damage metrics are greater than the baseline ones. Also, although the temperature level creates shifts of the damage metrics, this not caused false positives, enabling the technique to differentiate the damage to the pristine conditions.

The use of wood particles in cementitious materials in order to make them more sustainable as greenhouse gas emissions

Cement building materials are quite aggressive to the environment because of their manufacture causing large amounts of greenhouse gas (GHG) emissions, such as cement and steel. Wood-based materials are great in this respect, as they generally consume less energy for their production and wood stocks carbon in their structure, neutralizing CO2 emissions, the main GHG. But for various reasons, it is not always possible to apply purely wood materials. This work shows two cementitious building materials, concrete blocks and closing panels, which were developed in researches at the Federal University of ParanÃ¡ (UFPR - Brazil), which contains wood particles in its composition. These materials, in substitution of the corresponding traditional materials, mitigate GHG emissions by the construction works, without causing technical losses. The materials developed in the cited researches are produced with Portland cement, lime and wood particles. The carbon fixed by the wood plus the CO2 absorbed from the air by the carbonation of the lime during the first years of useful life neutralizes the majority of the GHG emissions of its production.

Entrepreneurial Intention of Undergraduate Students from a Municipal Public University of the State of SÃ£o Paulo - Brazil

The central proposal of this paper is to to study the entrepreneurial intention of undergraduate students, both beginners and those in the process of completing, at a Municipal Public University in the State of SÃ£o Paulo - Brazil. Therefore, the research method used a quantitative approach, using a closed questionnaire with a Likert scale, developed by LiÃ±an and Chen (2009) called the Entrepreneurial Intention Questionnaire. The data analysis was divided into 2 stages: the reliability analysis by Cronbach's Î± and the exploratory factor analysis. As a result of the research, it was found that the entrepreneurial career is perceived as favorable by the students of management, economics, and accounting sciences from different periods, being more attractive than formal work. However, pursuing an entrepreneurial career is not necessarily a positive alternative in the opinion of those around the survey respondents to the point of being encouraged by families, friends, and colleagues. Finally, students consider that their knowledge about the mechanisms to support entrepreneurial practice is limited within the analyzed institution.

Air quality and microbiological control in a hospital in ParaÃba, Brazil

Hermano Zenaide-Neto, JosÃ© Soares do Nascimento

An elevated quantity of pathogenic microorganisms can be an indicator of poor air quality, putting patientâ€™s health in hospitals at risk. The sanitation of the refrigeration systems must be carried out efficiently and with the right products, capable of maintaining reduced levels of hospital infection. In this work, the aim was to analyze the fungal density in the air of a private hospital, located in JoÃ£o Pessoa-PB, Brazil. The effectiveness of the disinfectant used to clean air conditioning systems in these environments was also verified. In an in vitro experiment with ThilexÂ® disinfectant against common microorganisms in the hospital environment, the antimicrobial activity, concentration and time of action were evaluated. For the analysis of the air in refrigerated places in the hospital, a bio-aerosol impactor was used to quantify the pathogens. The antimicrobial test indicated that ThilexÂ® was effective against Klebsiella sp., Escherichia coli and Candida albicans, while Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus sp. and Aspergillus sp. presented resistance at the concentration of 2%, being controlled up to 20% of the product in distilled water and exposure time above 1 minute. The hospital's air samples indicated that 12 of the 23 rooms had a fungal density above the acceptable limit according to the current national regulatory standard, with a higher prevalence in obstetrics rooms. The most common genera were Aspergillus sp., Penicillium sp. and Monilia sp. These results indicate urgency in the development of more effective public policies in reducing the risk to patients exposed to low air quality in hospitals.

Situations of Obstetric Violence from the Perspective of Puerperal Women

To investigate situations of obstetric violence in the perception of puerperal women in a teaching hospital. Descriptive study, with a qualitative approach. Data collection used a semi-structured interview with 17 puerperal women. The puerperal womenâ€™s statements were transcribed and analyzed through content analysis in the thematic modality proposed by Bardin. From the analysis of the statements, four thematic categories emerged: 1) Disrespect for the parturient, 2) Obstetric violence, 3) Violence revealed, 4) Unknown violence. The study revealed the need for changes in childbirth care to make is more welcoming, with pregnant womenâ€™s protagonism, respecting their rights constituted by laws, and using good obstetric practices for a humanized childbirth free of violence.

The Importance of Traceability of Implantable Medical Devices for Safety of Patients and Hospital Institutions: A Narrative Review

Implantable medical devices are materials that assist or replace partially or totally for the purpose of preventing, treating, or compensating for a disease, injury, or disability. It is important to follow patient safety protocols such as effective communication, safe surgery and regulations to ensure the procedure free of risk and damage. To verify the predictors that guarantee safe use and comply with the safety of the patient and hospital institutions. This is a narrative study, which sought articles published in the past 10 years (2009 to 2019), in Portuguese, fully available. The following data platforms were consulted: BDENF, LILACS and SciELO. Research was conducted through original articles, theses, dissertations, booklets, collegiate board regulations, regulation of ANVISA and handbook of good practices, all in the Portuguese language. The data were organized and presented in figures and tables. Of the 87 articles found, after reading the abstracts, 04 studies met the inclusion criteria and were thematically specified, classifying the knowledge elaborated on the subject. The research reflects on the importance of presenting labels and controlling the use of devices to ensure the safe use of the material. However, there were no Brazilian publications specifically on the theme and, in this sense, quantitative and qualitative researches on the subject should be developed.

A comparative study of some well-reservoir coupling models in the numerical simulation of oil reservoirs

Rebeca Costa Dias do Rosario, Grazione de Souza, Helio Pedro Amaral Souto

In reservoir simulation, the most known well-reservoir coupling technique is based on the Peacemanâ€™s equivalent radius, which is applied on the productivity index computation, that is used to relate flow rate, wellbore pressure, and the mesh block pressure. Original Peacemanâ€™s model considers the assumption of steady-state flow, leading to an artifact on the calculation of the wellbore pressure, called numerical wellbore storage. This artifact is more significant for coarser meshes and initial time instants, and it is also a function of fluid and rock properties. In this context, we have implemented and compared different Peacemanâ€™s technique extensions for productivity index calculation incorporating transient effects to prevent numerical wellbore storage. We have also considered some production scenarios for a vertical well and single-phase oil flow.

Ricardo De Bonis, Sergio A. L. de Souza, Hilton Koch, Milton Costa

Background: The temporomandibular joint (TMJ) is a synovial condylar articulation with freedom of movement resulting from bilateral side morphological interrelations. Its basics movements to attend its main function are rotation and translation. Material and Methods: A videofluoroscopic study of the left posterior oblique incidence comprising 23 healthy volunteers of both sexes was conducted to qualify and quantify the displacement of the mandible over the temporal surface. This evaluation was performed without using any artificial contrast medium. Results: From maximum occlusion to maximum mouth opening, three spaces defined as LL1, LL2 and LL3 were established and used to qualify and quantify the limits of mouth opening. Seventeen volunteers could be classified as normal free (NF) and six as suspicious (S) based on this function. Conclusion: The NF and S groups statistically differed in their mouth opening capabilities (p < 0.0001). Measured values for LL3 greater than LL2 as well as positive values for L3-L2 can be considered NF and negative values for L3-L2 can be considered S with a significance of p < 0.0001. L2 was statistically confirmed as a good parameter for the distinction between normal and suspicious TMJ functioning.

Optimizing the process of extraction and acid hydrolysis for Amazon and Cerrado biomass

We investigated the effect of the reaction variable (time) on the extraction and hydrolysis process. The data showed that the methodologies of the National Renewable Energy Laboratory (NREL) must be adequate for each type of biomass and each regional reality. For the contents of total sugars in the biomass of green coconut, babassu and Brazil nut shell epicarp, the highest yields were found under different conditions from those proposed by NREL. In the total lignin content, the highest yields obtained were those proposed by the NREL method for all biomasses. In the content of extracts for coconut and babassu, the use of longer extraction time provided greater removal. For the chestnut fractions, shorter times led to higher yields. It is important to note that, with the optimized results, these biomasses can be used in the production of high value-added bioproducts with higher yields.

Nursing Assistance and Fragilities in Tuberculosis Diagnosis: Integrative Literature Review

Objective: This study aims to analyze scientific publications on nursing care and fragilities in diagnosis of tuberculosis. Method: It is an integrative review of the literature by searching the databases, with the time frame between the years 2015 to 2020. For the treatment of the data, the technique of content analysis was used, with categorization of the findings. Seven complete original articles were selected that answer the central question of the research, which were grouped in tables according to author, title, journal, year of publication, indexing base, objectives, methodologies and evidence. Results: The analysis of the literature made it possible to elaborate three categories based on relevant points, namely: Category 1- Primary Health Care as a gateway to the diagnosis of tuberculosis; Category 2 - Qualification of nursing actions in the diagnosis of tuberculosis and Category 3 - Factors of delay in diagnosis related to the patient. Conclusion: This study made it possible to understand about the magnitude of the problems inherent to society as a whole, of a political and social order, as well as the health system and the organization of the health services that comprise it and influence the delay in diagnosis. However, the importance of the nurse's performance in the context of Primary Health Care in the process of decentralization of services and in equitable and comprehensive access to the patient is emphasized.

Growth and accumulation of macronutrients in arugula

In Brazil, arugula is a vegetable often consumed in salads because it provides a flavorful option when paired with blander lettuces and because it is considered rich in vitamins A and C, potassium, sulfur and iron. However, several aspects of fertilization management for this crop must be studied further. Thus, the objective of this work was to determine the growth and accumulation of macronutrients within arugula, under field conditions. The experiment was conducted in four parcels (vegetable beds) with dimensions of 5.0 x 0.2 x 1.3 m, located within an experimental area of 54 mÂ² (6.0 x 9.0 m). The Arugula cv. Cultivated, with seedlings produced in a protected environment. Standard fertilization was performed with 160 kg ha-1 of N, 340 kg ha-1 of P2O5, 160 kg ha-1 of K2O, 20 kg ha-1 of S and 1 kg ha-1 of B. The treatments were constituted by different collection times at 7, 14, 21, 28, 35 and 42 days after the arugula seedlings transplanting. Between 18 and 38 days after the transplanting of the seedlings, a significant increment in the accumulation of dry matter occurred. In the period between 20 and 30 days after the transplanting, the greatest demand for most macronutrients occurred. The order of macronutrient accumulation by arugula at 42 days was as follows: K > N >Ca> P > Mg > S.

Financial risks, then, faced by broilerâ€™s breeders are minimal capital, fearsome to lend to bank and higher input price, Based on the value of Risk Priority Number (RPN), sources of primary risk becoming inhibiting factors on success of broiler farm in Regency of Minahasa Utara, consecutively, are performance index target-based profit, disease outbreak, broilerâ€™s mortality, sold broilers in lived condition and risk of capital loan from banking sector.

Effects of the binaural wave as a stimulus for student hyperattention: brain frequency records without interactive media context

The brain works with electrochemical, generating brain waves that represent brain activity. The basic frequencies of brain functioning are gamma (30-70 Hz), beta (13-30 Hz), alpha (8-13 Hz), theta (4-8 Hz), and delta (1-4 Hz). With these references it is possible to condition the electrical activity, inducing a specific wave pattern. The way for this to happen is through binaural waves to synchronize brain patterns. This technique is addressed in this study, in the context of interactive media and in the student's attention stimuli, so the sounds are received independently in each ear creating different effects in parts of the brain.

Normalization of Way Ruhu River in Hative Kecil, Galala and Aster Villages in Sirimau District, Ambon City

Rudi Serang

Way Ruhu River is one of the watersheds in Sirimau District, Ambon City. The limited handling of the city government and the awareness of the local community to expand residential areas in the Way Ruhu watershed resulted in floods and landslides that brought sedimentation and garbage, this caused shallowness that occurred on the riverbed, thereby overflowing river water into the residential area of Hative Kecil, Galala. and Aster. To overcome this problem, an intensive study and periodic handling of sedimentation and garbage on the riverbed is required by periodically backfilling the Way Ruhu river area. Therefore, the analysis of sedimentation and garbage in the Way Ruhu river needs special handlers to deal with the overflows of water that occur every rainy season in the villages of Hative Kecil, Galala and Aster. This study aims to overcome water overflow caused by the accumulation of sedimentation on the riverbed so that there is no flooding, by backfilling the riverbed. The results of the analysis of this study indicate that most of the Way Ruhu river area has been damaged by water-fed land which has been turned into residential land which has resulted in flooding and landslides in the Way Ruhu watershed area. The sedimentation rate that occurs in the Way Ruhu river watershed averages every year of: 3,599 m3 / day or 1,313,635 m3 / year. So that the sedimentation that is carried out of the river is as much:32,386mÂ³/ dayi atau 11.954.078 mÂ³/ year

Henrique Pereira de Aquino, RenÃ© Geraldo Cordeiro Silva Junior

This article is an excerpt from the research entitled â€œPotentialities and Weaknesses of Artisanal Fisheries and Pisciculture in Tanque Rede in the Municipality of Sobradinho-Bahiaâ€, whose objective was to get to know the current reality of family fish farming and business fishing in the Sobradinho lake, specifically in the city of Sobradinho where this practice excels in the sub-middle SÃ£o Francisco region. It is a quantitative and qualitative research, involving documentary analysis in the fishermen's colony, interviews recorded with the use of forms, both with artisanal fishermen and with businessmen, in order to diagnose their ways of life, work and future expectations. The sample consisted of twenty fishermen and family fishermen and six entrepreneurs who raise tilapia in a net tank, chosen at random. The data were processed by the software SAS - Statiscal Analysis Sistem, where the variables were registered in the columns and the observations in the lines, pointing out that extractive fishing is decreasing, due to the reduction of species in the SÃ£o Francisco River, while fish farming net tank is on the rise in the municipality, given the favorable environmental conditions, with a positive impact on the food security of the riverside population.

Experimental Review on â€œEvaluation of Antimicrobial activity of Metabolites from the fruit coat of Cucumis Sativusâ€

Skin inflammation vulgaris is the most broad skin illness and a persevering incendiary issue influencing 90-95% of young people. Irritation is because of the over multiplication of Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. Numerous manufactured makeup have been created for the treatment of skin break out. Be that as it may, they are known to have many reactions and are found to get safe after some time. In this manner, the current work was embraced to explore a characteristic restorative plant, Cucumis sativus separates, for their enemy of oxidant, antimicrobial potential and its corrective incentive in treatment of skin break out. Results demonstrated the nearness of all out phenolic content (19.25 Î¼g and 6.23 Î¼g GAE) and flavonoid content (1.82 Î¼g and 6.24 Î¼g catechin in new and dried concentrates individually. New concentrate of Cucumis sativus showed promising antibacterial potential and was blended in with tea tree (Melaleuca alternifolia) oil and linseed (Linum usitatissimum) oil to get ready polyherbal cream (O/W) details . Details were additionally assessed for pH, consistency and different physical boundaries. F5 cream definition indicated pH in scope of 5-6.

Utilization of pequi Residual Biomass from the Brazilian cerrado for obtaining raw and activated biochars and bio-oil

The pequi (Caryocar brasiliense Camb) is a fruit native to the Cerrado, with a production of 765 tons per year. However, their peels (76% of the fruit) are generally discarded. In this study, the physical-chemical characterization of the biomass of the pequi was carried out and physical activation processes were developed through slow pyrolysis and physical chemical activation with zinc chloride (ZnCl2) to produce bio-based products, including bio-oil (30.5%) and biochar (34%). Analytical techniques, such as mid-infrared spectroscopy, gas chromatography coupled with mass spectrometry, surface area, pore size, approximate and elementary analysis, helped to elucidate, identify and quantify such compounds. The biochars produced showed a low surface area of 30,30 mÂ²/g (BET) and 39.11 mÂ²/g (Langmuir), however the superior calorific power of activated carbon (29.59 kJ.g-1) and raw coal (26,92 kJ.g-1) highlight the potential of biochar for use as a solid fuel. Bio-oil, on the other hand, presented valuable chemicals in its fraction, such as vaccenic acid (21.23%), palmitic acid (19.73%) and furfural acid (7.04%).

Non-Technical Losses in Light's Concession Area

One of the critical problems that electricity distribution companies come across are non-technical losses, also known as commercial losses. These losses impact the economic and financial balances of the electricity distributors, limiting their ability to make further investments. In the state of Rio de Janeiro, the major non-technical losses take place in urban informal settlements (slums). They emerged in the cityâ€™s hills as a response to hygiene policy in the early twentieth century. Throughout time, they expanded to peripheral zones and many are dominated by criminal groups, which are responsible for limiting the operation and supervision of electricity distribution companies, preventing adequate actions against non-technical losses.

The Importance in choosing the team in project management

Gabrielly Raquel Izidio Ramos

In project management, it is necessary that the tools, techniques and solutions are applied in pursuit of a goal. It is also essential that the scope, deadline and costs are met. As a result, the satisfaction of the stakeholders, who are the interested party in the projects, are satisfied. For this reason, developing an efficient and qualified team can be considered a great challenge for the Project Manager, but it is something totally necessary for effective results. For this reason, it is required that the manager has good characteristics such as: being a good facilitator, innovator, motivator, goal-oriented, and above all, knowing how to lead their leaders. Therefore, to build a highly qualified team he has to analyze the type of project in which he has been assigned, analyze employee profiles and experience, so that they are compatible with the project and the number of people who will be available. It is also important that team members know the life cycle phases of a project (start, plan, execute, control and close). In view of all these prerequisites, it is essential that the manager, besides having the leadership profile capable of being flexible according to the maturity of the team, has the discernment to choose the people who will be part of the team, in order to achieve success.

The Importance of Environmental Awareness for Minimizing impacts in a Food Company

Environmental management is a continuous and adaptive process, through which an organization determines its objectives, goals and strategies related to the protection of the environment and the safety of internal employees, customers and the community, based on the quality management of processes, products, services and interaction with the external environment. In this way, this work aims to raise awareness based on the relationship of environmental responsibility to minimize the organizational impacts on the lives of employees of a company in the food industry. The main interest is to examine in a more systematic way the perception of employees of a chain of sushi about their social responsibility in the activities they perform, in order to better understand their dynamics, their obstacles, possible solutions, as well as the reception of these employees for actions of this nature. First, there was a bibliographic survey of studies that discuss the issue of environmental education as well as the management of solid waste. Then, the chosen research sites were visited, in the Municipality of Manaus, capital of the State of Amazonas, where the way the employees perform their tasks and dispose of their waste was observed. At the same time, a questionnaire was applied to these professionals, in order to understand their knowledge about the theme. Lectures were also held in order to make them aware of the importance of their involvement in the processes and dynamics to be proposed. The study revealed that although there is a certain awareness about the negative impacts caused by the interference of solid and liquid waste, there is a gap between being aware of the problem and being aware that it is possible, with sincere dedication and few resources, to encourage some changes conducts, aiming at higher environmental quality, and even greater profitability for the company. The goal of being a green company must be incorporated into the future vision of the enterprise and that all employees are engaged in these results.

Henrique Luis da Silva, Gislaine Gabardo, Roger Daniel de Souza MillÃ©o

The reduction in the availability of drinking water to populations has stimulated the search for alternative forms of technologies that enable the use and reuse of rainwater for non-drinking purposes, which are associated with practices that contribute to the reduction of waste. Thus, the aim of the present work was to propose a model for capturing rainwater and to identify the demands for the use of non-potable water for an agricultural research unit, in order to replace the current model with a more sustainable one. The work was carried out in a research station of IDR-ParanÃ¡-Institute of Rural Development of ParanÃ¡ â€“ Iapar-Emater, in the municipality of Ponta Grossa, ParanÃ¡. Three factors were evaluated: precipitation, collection area and demand quantity in each activity. The system is feasible to be implemented. The maximum demand for a month of higher consumption was estimated at 56.700 liters. It was possible to estimate the intake for the month with the lowest precipitation at the site, with this volume exceeding 46.000 liters of water, a value sufficient to meet the unit's demand for washing vehicles and for use in agricultural spraying, contributing to the reduction of use of drinking water at the station. Water use technologies are sustainable solutions and contribute to the rational use of water, providing the conservation of water resources for future generations.

Surface Water Quality Modeling of a watershed in the north of Rio Grande do Sul

The water crisis and the degradation of surface water resources through pollution, combined with the progressive increase in consumption has made it necessary to search for alternative sources of supply.. Because it is a finite natural resource, water is a public good that needs to be allocated among different uses and has its integrity compromised by factors such as industrial development, rapid urbanization and population growth. Considering these issues recognize and evaluate the potential of local water resources is necessary, since the River Inhandava is inserted in the north-northeastern state of Rio Grande do Sul, in the Uruguay river basin and watershed belongs to ApuaÃª-Inhandava. The objective of this research was to perform the modeling of surface water quality of the River Inhandava-RS. The data were inventoried quality of studies conducted in Rio were considered diffuse agricultural loads, animal waste and sewage. To assess the water quality of the Rio Inhandava, the computer model was used QUAL2Kw. The water quality has been shown, for most parameters, according to Resolution CONAMA 357/2005. The calibrated model QUAL2Kw, became an instrument to in the management of water resources, since the analysis of the results showed the selfpurification in downstream river study.

Productive Performance of Tomatoes under Fertigation Management

Tomato is an important global commodity, with high socioeconomic expression in Brazil, due to consumer preference and wide availability of varieties.

Short-term Load Forecasting using Combined Data from Several Weather Stations

Guilherme Guilhermino Neto, Henrique S. Hippert

In order to schedule the load generation and distribution, operators of energy markets rely on short-term load forecasts, especially those made for the next few hours. Since it is not feasible to store a large energy amount for compensating unbalances between supply and demand, what lacks or re-mains must be exchanged with an interconnected system, at the latest time price quotation. One of the new interests in this research field is the hierarchical load forecasting. The latest smart grid sys-tems made possible to monitor real-time load at various levels of aggregation, from households to the whole system, which brought interest to forecasting from the whole system to a sole household. Some levels may comprise large geographical zones, on which more than one weather station may be located, and that raises a question: how to combine data from more than one weather station, and use the combination as input for load forecasting models? On this paper, we combine data from sev-eral weather stations by giving more weight to those stations closer to the centroid of the load zone. We experiment on data from a load zone in the state of New York and 11 weather stations spread throughout the state, using the combined data as input for neural networks. In our datasets, the pro-posed combinations lead to better results than those from neural networks that use of any of the 11 stations individually. Also, the proposed method outperforms several statistical time series bench-marks.

OLIVEIRA Paulo Antonio Barros, RENNER Jacinta Sidegum

This research aimed to understand the perception of operators, supervisors, and managers on the causes of work accidents, risk, danger, and human error. In addition, it sought to identify convergent and divergent issues among workers at different positions and functions. We used the case study method with qualitative data analysis, in a footwear company located at Vale do Paranhana (Rio Grande do Sul, Brazil). Although human error is usually considered the cause of work accidents, results showed that there are problems in both the work process and work organization. These impose an accelerated pace dictated by conveyors that does not always allow proper care in order to prevent accidents. Other causes of accidents mentioned are the lack of safety training and the configuration of machines and equipment that allow for failures, errors, incidents, and accidents.

Teaching Mathematics: Low Performance in Mass Evaluations

FÃ¡bia Maria de Souza, Roberto GrÃ¼n, HÃ©lio Raymundo Ferreira Filho

External performance evaluation processes of students in Brazilian schools have shown low retention and/or learning of knowledge provided for in the legislation. More precisely in the area of Mathematics, some indices have decreased in the latest evaluations, such as the National High School Examination (ENEM in Portuguese) and the Programme for International Student Assessment (PISA). This reality requires deep reflection, structured on research and dialogues between peers and agents, and to do this, data must be collected. In order to understand the results of the mass evaluation processes of Brazilian education, quantitative research was carried out using secondary data collection techniques. The results indicate that the evaluation processes show an insufficiency in the students performance averages, and Mathematics is the area of knowledge with the lowest indexes, both in internal (such as ENEM) and external (such as PISA) evaluations.

The effect of underdrain box storage (UBS) as an instrument for reducingwater runoff in Mardika residential areas at Ambon City

Obednego Dominggus Nara, Paulina Limba, John Rikumahu

Land use change due to housing development can damage water catchment areas indirectly. This condition results in reduced rainwater catchment areas which cause rainwater to collect in existing drainage channels.Underdrain Box Storage is a means to collect rainwater and soak it into the ground. Rainwater that falls on the roof of the house is not flowed down into the gutter or the yard of the house, but it is flowed by using water channels into the underdrain box storage (UBS) so as to reduce the amount of runoff that occurs. Based on the results of the analysis of the combination of the correlation curve between Fr and Q2 / (h15.g)1/2, it is found that the regression model Q2 / (h15.g)1/2= 0.25757Fr2 - 0.612Fr + 0.0064 and between Fr and a / h12 in the model regression a/h12 = 0.1Fr2 with the formula of flow through the hole with Cd the discharge coefficient of the contraction vein flow equation at the bottom of the tank is Q = Cd. (2gh)1/2, found the discharge coefficient (Cd) with a value of 0.85-0,96 with the regression model Cd = 0.6473.h0.144. The area of the hole for the underdrain storage box has 2 "(inch) as a diameter and the filling time which is planned to speed up the entry of water into the reservoir is 2 minutes due to the small diameter of the holes, so that the required number of holes is 12 with a distance between the holes is 13.5 - 14 meters. If there rain happened for 1 hour, the underdrain box system can reduce flooding / inundation by 25.47% for the 2-year plan rainfall 11.44% for the 5-year plan rainfall and 7.35% for the 10-year plan rainfall of the total water volume rain.

Anchoring elements for fiber optic sensor cables: part of a system for monitoring slopes surface movements

The fiber optic industry had a significant development from the late 80's. Besides communication, this technology is also being used for measuring a monitoring deformation, displacement, acceleration, pressure, temperature and chemical properties among others (MORIKAWA, 2004). Among the technological advantages of the use of fiber optic sensors, the most notable are: (i) sensing the possibility of several signals over a single optical fiber (multiplexing data), (ii) ease of reading of the signals (good value signal versus noise), (iii) measurements over long distances (remote sensing), (iv) immunity to electromagnetic fields, (v) absence of spark, and (vi) low weight and low material reactivity. The use of fiber optics as a tool for different kinds of geotechnical monitoring can become a highly attractive and cost effective when compared to conventional instruments such as piezometers, inclinometers, among others. A single fiber optic cable may cover a larger monitoring area compared to conventional instrumentation, and the possibility of monitoring more than one physical quantity with the same fiber optic cable. This paper covers all steps undertaken to define the size of one type of cable Anchoring Element (AE) for monitoring soil movement in natural hillslopes. To fulfill this objective laboratory tests were carried out in LACTEC, Curitiba-PR, and results and conclusions are shown in this paper.

Epidemiological and toxicological profile of a community exposed environmentally to mercury in the amazon

Objective: to know the epidemiology and the toxicological profile in relation to the total Hg in the sample of the population of Sena Madureira, in the State of Acre, northern region of Brazil. Method: Cross-sectional, population-based, descriptive study with a quantitative approach. Result: The sample consisted of 302 484 people from a community in the municipality of Sena Madureira, state of Acre, Brazil, located southwest of the northern region of Pan-Amazon. This study found that total blood and hair Hg levels were above the limits considered safe by the World Health Organization. The presence of total Hg in the blood and in the capillary matrix shows that the population of the municipality of Sena Madureira is environmentally exposed to metal. This exposure occurs through the existence of the biogeochemical cycle with the participation of fish consumption and the anthropic activity of artisanal gold mining in the bordering region of the state of Acre. Conclusion: The high content of total Hg in the biological matrices of the studied population indicates the physiological dynamics of the metal in the organism. The distribution of mercury in both sexes and in different age groups, suggests that there is a significant risk to the health of individuals, especially women and children.

Technological characterization of wood residues from the Amazon for the production of briquettes*

The study aimed to evaluate the potential of briquettes produced from wood residues from five forest species in the Amazon. Wood residues were obtained in Manaus - AM/Brazil, fragmented to obtain sawdust and determination of the Physical and Chemical Properties of wood, coal and briquettes. In chemical analysis, Extractives ranged from 9.76 to 12.08% , and the Ash content was 0.48% on average. As for physical properties, Basic density ranged from 870 to 980 Kg/m3, Moisture from 7.38 to 9.03%, and PCS from 5,213.50 to 5,883.50 Kcal/Kg. The PCS of coal was higher than that of wood, and the best correlations of PCS were with Extractives, Lignin, Moisture and Basic density. Regarding the DE estimate considering wood as firewood, JatobÃ¡ residues presented the highest valor, and this material when compacted (Briquette), the energy efficiency increased effectively with a range of 6.36 to 7.51 MKcal/m3. The material, when carbonized, presents a higher concentration of fixed carbon, which justifies the high DE values for both coal and coal briquettes, where in the coal a variation of 6.25 to 8.51 MKcal/m3 and coal briquettes from 8.01 to 11.42 MKcal/m3. The studied residues presented high PCS, both wood and coal. In general, all species showed high Basic density and low Moisture, which favors the indication of these materials for energy purposes. Charcoal briquettes from Angelim pedra and Angelim vermelho showed Energy density above 10.00 MKcal/m3, indicating the energy potential of this product that combines technical and economic viability.

It is observed the existence in the country of legal parameters that regulate the conditions of use of the waters for bathing purposes; yet accompanying the national reality is evident the fragility in the inspection of these norms, constituting this point, at risk the health of the people versus economic return through the generation of income, in a real area of interest of social-environmental management and human ecology. The methodology proposed for the research is the bibliographical research, the case study and the ethnographic research. The objective is to demonstrate, from the normative point of view, the bathing conditions of Prainha de Paulo Afonso. Obtaining as a result the verification of the real conditions of use (leisure and tourism) of that space of entertainment and the recognition of the service, or not, of the normative conditions required by the supervisory body.

Influence of the coefficient of thermal expansion on the stress distribution in ceramic veneers after thermal simulation

The aim of the study was to evaluate the stress distribution in the ceramic veneers in a full prosthetic crown with different framework after the sintering and cooling cycle through the thermal analysis by three-dimensional finite element analysis. Using images from a computerized microtomography of a central incisor, an anterior crown was constructed. The models were composed of 2mm thickness ceramics (feldspathic ceramics) and 0.4mm thickness frameworks(zirconia, alumina, lithium-disilicate, or metal). Ansys Workbench finite element software was used for analysis and mesh generation through a 5% convergence. The thermal loading was performed in 2 stages simulating the heating and cooling of the ceramic veneer sintering cycle: stage 1 - 403 to 750 degrees C; stage 2 - from 750 to 25 degrees C. The von Mises equivalent strain(ÏƒvM) was used for the quantitative and qualitative evaluation of the framework. The maximum (Ïƒmax) and minimum (Ïƒmin) stresses were used to evaluate the ceramic veneer and zirconia, alumina, and lithium-disilicate frameworks. The highest values of compressive stress (294,58 MPa) were found in the ceramic veneer in the models with alumina framework, followed by models with zirconia (253,65 MPa), palladium silver (239,74 MPa), and lithium disilicate (205,43MPa). The tensile stresses followed the same behavior presenting the highest values in the alumina prostheses (Al: 93,977 MPa, Zr: 76,358 MPa, Ps:68,193 MPa and Ld: 56,573 MPa). The ceramic framework alumina and zirconia cause a higher stress concentration in the ceramic veneers. The stress concentration in the ceramic veneers was affected not only by the coefficient of thermal expansion but also for the mechanical properties of the framework materials.

Perception of the Nursing Team in Relation to Oncologic Patient Assistance in Palliative Care in the Intensive Care Unit

Introduction: The palliative care in general should retake the possibility of perceiving death as a natural and expected process, facing a life threatening disease. Even if there are efforts aiming toward Palliative Care in the ICU, there are still difficulties that hinder such practice, by the fact that it demands individual activities toward the patient. Objectives: describe the perception of the nursing team in relation to oncologic patient assistance in palliative care admitted to the ICU. Methodology: Descriptive, transversal, quali-quantitative study, with field data collection, in which 29 nursing professionals were interviewed through an individual questionnaire, made by the researcher herself in a hospital from RondÃ´nia countryside in 2020. Results: it was possible to prove that the Palliative Care theme is still not widespread and lot of professionals donâ€™t know its principles, such reality hinders the care in relation to these oncologic patients admitted to the ICU. Conclusions: It stands out, then, that there is a need for the nursing team to be ready to attend oncologic patients, just as it becomes evident the teamâ€™s interest over the presented theme. To offer continuing education about intensive care is essential, just as providing an emotional support to these professionals who deal everyday with pain, suffering and death.

Computational modeling of atmospheric dispersion applied to a small modular reactor

This study describes the computational modeling of the atmospheric dispersion resulting from a postulated radiological accident in a small modular reactor (SMR), with a power of 16 MWe (50 MWt), and containing three fuel enrichment regions, at 4%, 5 % and 20%. Among the hypothetical inventory radionuclides, derived from nuclear reactions during fuel burnup after 2 years of operation, the contribution of Cs-137 was considered for simulation, using the HotSpot code, of the concentration and total effective doses (TEDE) received, both depending on the distance from the event. A locality in the interior of Brazil was chosen to install the SMR, where information on meteorological conditions was collected to identify the predominant atmospheric stability class. The results suggest that the maximum calculated TEDE was 3.6 Sv, 34 m from the reactor, decreasing with time and distance, and following the Gaussian dispersion model, and that the contamination plume is dependent on the Pasquill-Gifford criteria and Cs-137 activity. For doses between 1 mSv and 10 mSv and between 10 mSv and 50 mSv, it is suggested that the population be housed in existing buildings in the locality, and for values above 50 mSv, shelter in these conditions or the evacuation of people close to the reactor in movement contrary to the spread of the plume. The relevance of this investigation shows the importance of emergency response planning and the influence of meteorological conditions, considering the data assumed in the simulation.

Almeirim Deus Da IncarnaÃ§Ã£o Jaime Nacarapa, LuÃs Borges Gouveia

This study analyses the impact of the implementation ofe-BAÃš platform for commercial licensing at the One-Stop Shop located in Nampula, Mozambique, in the period of 2014-2018. The e-BAÃš was introduced in 2014 as a result of the Mozambican Public Administration Reform and the improvement of the National Informatics Policy. In order to achieve the objective of this study, the following question was defined: to what extent does the implementation of the Electronic One-Stop Shop contribute to the improvement in the provision of public services? Methodologically, the study is document based with a qualitative nature and it involved six interviewees and it used the thematic content analysis technique for data analysis. The obtained results indicate that the implementation of the e-BAÃš allowed the principles of speed, debureaucratization, flexibility in commercial licensing processes to be achieved, in addition to support revenue generating for the State Treasury. Despite these advances, it is understood that the e-BAÃš still requires the creation of a quality platform that has interoperability capacity with other sectors and institutions of the State or the private sector that are part of the commercial licensing process and that has the capacity to detect false and expired documents avoiding fraud and errors.

Mobile Applications for autisticchildren: An analysis of the Google Play Store platform

This study aims to categorize mobile applications for autistic children available on the Google Play Store platform, analyzing how these applications are arranged on the platform and how to best facilitate the search function for parents and professionals working with autistic children. The process should ease search and access of specific applications for parents and professionals working with autistic children by arranging applications from diverse areas in a table format rather than requiring that apps be checked individually in the search engine on Google Play Store. Methods: the survey was conducted in three stages: identification of all applications for autistic children; mapping and categorization of the 10 most installed applications; analysis of the features and benefits of the two applications selected. The survey qualifies as qualitative, since it proposes a survey of mobile applications for children with ASD, arranged on the Google Play Store platform. Thus, we describe the main characteristics of the selected applications, their purpose, features and benefits for use with autistic children. Conclusion: at the end of the survey, it was concluded that the 249 applications found were poorly organized and that only 44 were specific to autistic children. Of these, 10 applications were selected and arranged in a table to facilitate search for parents and professionals working with autistic children. In addition, 2 mobile applications were selected and analyzed for their purpose, functionality and benefits.

Evaluation of Quality of Life at Work in a Third-Party Company

The Quality of Work Life (QWL) is strictly related to satisfaction of employees and the function he/she plays in a company. In this way, QWL should is handled within an institution/company in order to provide a better work environment and conditions to staff. Despite this, many Brazilian institutions still do not exploit QWL to improve productivity. Besides that, they tend to underestimate such a tool due to its association with workersâ€™ satisfaction. The present study had the aim of evaluating the QWL within an outsourcing company, taking into account the employeesâ€™ points of view. There were applied 13 questionnaires, randomly distributed among collaborators, in July 2017. For this, the questionnaires contained 24 questions, where 17 of them were distributed into five different satisfaction dimensions. The level of satisfaction was classified as high, average, and low, for each one of the dimensions. The results, obtained from the questionnaire, were exhibited through figures. The verification of satisfaction pointed to some of the companyâ€™s weaknesses, considering that the level of satisfaction of some dimensions was qualified as average.
