Predictive maintenance is a recent maintenance model on the market, although it is already well known in the aeronautical industry, and it is increasingly necessary in any manufacturing environment. The research project aims to develop low-cost reduction nodes for predictive monitoring of machine health, increasing production performance and reducing long-term maintenance costs. Integrated with the concept of Internet of Things (IoT) and data processing, it will result in a tool to increase machine reliability. Precisely because it is a low-cost development, which will be developed in a laboratory with hardware and commercial sensor, the main challenges of the project is the dimensioning in such a way that it meets the requirements of an industrial environment and is economically advantageous. In addition, once developed, the technical staff responsible for monitoring must be trained to correctly read the information that will be treated and provided from a communication platform with the cloud. Another challenge of the research is to be able to install the prototype developed in a factory and prove the efficiency of the method. The focus of the main research is to develop a predictive monitoring device that is easy to install and operate with low cost, integrated with data treatment via the cloud and possible Application for industry. Once this goal is achieved, the device will be tested in a laboratory and industrial environment for study validation and data comparison. The study will focus on comparing the performance of machines with and without monitoring via a device developed in the research, in order to prove the importance and necessity of predictive maintenance aligned with data processing in the industry.

Variable selection has been a topic of great interest for statisticians and researchers alike. The choice of the best subset of predictors may be carried out with the objective of improving prediction or for easier interpretation of results. However, such methods are not always straightforward, mainly in the context of linear mixed-effects models. Variable selection for such models must be carried out for both fixed and random effects, the first being related to the global mean of data and the second to subject-level variance. There are two possible approaches when selecting variables for mixed-effects models: joint or two-stage procedures. In existing literature on the topic of variable selection for linear mixed-effects model, there is a method of joint selection via lasso for linear mixed-effects models under a normal distribution. Another topic of remarkable importance, is diagnostics and residual analysis. While residual analyses are carried out to assess issues with the fitted model and identification of atypical observations, diagnostic analyses are carried out assuming the model as correct and, assessing its conclusions robustness to small disturbances in the data and/or the model. There are many possible ways to deal with such observations. One is using robust models, which are said to be robust to disturbances in the data. That is, models that are better fit to data sets that possess observations considered to be as outliers and/or leverage. This work aims to use the robust method for variable selection in linear mixed-effects model and compare it with the normal method using diagnostic analysis.

The use of agro-industrial residues associated with enzymatic process technology has encouraged the development of new strategies for obtaining bioproducts, such as galactooligosaccharides (GOS). The β-galactosidase enzyme is widely used on production of lactose-free products and, recently, studies on the production of GOS have emerged to take advantage of the main residue of dairy industries – cheese whey. This is a substrate rich in lactose, contributing as an alternative and low-cost source for obtaining GOS, oligosaccharides that act as prebiotics. One way to obtain GOS is using the enzymatic immobilization technique, which allows for several advantages, including the reuse of the biocatalyst, the reduction of maintenance costs and the improvement of thermal stability. In this context, this project aimed to study the use of porungo cheese whey, a dairy product characteristic of the southwest of São Paulo, to produce GOS through the immobilized β-galactosidase enzyme. The work was divided into two moments, in which, in the first, two enzymatic immobilization strategies were evaluated (calcium alginate and calcium alginate-Concanavalin A) in relation to the optimum pH and temperature of the enzyme. In the second moment, obtaining GOS was tested using the most promising immobilization support on different substrates (lactose solution and cheese whey) and then from different concentrations of lactose added to porungo cheese whey (200 g L-1 to 400 g L-1) and temperatures (37 °C to 55 °C). Enzyme immobilization allowed us to verify an increase in the optimal pH range (7.0 to 7.5) for the calcium alginate support when compared to the free enzyme pH range (6.5), while for the calcium alginate support Calcium-Concanavalin A, a greater enzymatic activity was observed at lower pHs (6.0). With respect to temperature, a greater enzymatic activity was observed for the free enzyme in relation to the two immobilization supports tested. Higher GOS yields were observed in porungo cheese whey (63.2%) compared to the lactose solution (41.1%), which was used in the next step to evaluate the process conditions. The maximum GOS yield was 17.73%, with 61.4% lactose conversion, at 46 °C and 400 g L-1. These results suggest the possible use of porungo cheese whey as a substrate in the biotechnological production of GOS.

Different methodologies are proposed and explored aiming to reduce time series forecasting error. A promising approach consists in combining different forecasts from different models in order to get a better accuracy, i.e., a smaller forecast error. This work aims to review and apply the bootstrap aggregating method, also known as bagging, in order to improve time series forecasting. First, each time series is divided into training and testing time series, and then the moving block bootstrap methodology is applied to the training series to generate different resampled time series, and then forecasting for each one of the series is performed and combined, thus obtaining the final combined forecast. The test data set is used to calculate the accuracy of the models, individual and combined. A simulation study of time series and application to a real time series data sets are presented. The chosen and fitted model for each of the time series was an autoregressive integrated moving average (ARIMA). The accuracy measurements used were the mean square error and its root, mean arctangent absolute percentage error and the symmetric mean absolute percentage error. Finally, the impact on the forecasts of the combined model by varying the resampling method parameters was explored and comparisons between the combined and individual forecasting methods were also carried out.

Studies have showed that the relations between equivalence class stimuli can vary in function of numerous experimental parameters. However, few studies investigated the effect of consequences as an independent variable. This study is divided in three experiments, which have as general purpose to evaluate the effect of using reinforcing and punishing consequences in the formation and maintenance of equivalence relations. The Experiment 1 and 2 compared the use of contingencies of reinforcement and punishment exclusively or together, for training two potential classes of stimuli with four member each. It was used a traditional Matching-to-Sample procedure and the participants were distributed in three groups related with the consequences used: Reinforcement Group (R), Reinforcement-Punishment Group (R-P) and Punishment Group (G). A bigger number of participants in Group R reached the criteria for the formation of the equivalence classes when compared with the other groups. Experiment 3 had as specific objective an evaluation of the effect of the magnitude of the reinforcement and punishment consequences in the formation and maintenance of equivalence classes. For data collection, a gamified version of the MTS (the game Miner Troubles, developed for the study) was used, adapted for online data collection, due to limitations resulting from the Covid-19 pandemic. 56 people (between 18 and 57 years old) participated in the research, randomly distributed among three groups: the More-Earning Group (M-E), the Balanced Group (B) and the More-Loss Group (M-L). In the first group, the participants gained 4 points when they choose correctly and lost 1 point when making a mistake; in the second group, the participants gained 1 point when they choose correctly and lost 1 point when making a mistake; and in the third group, the participants gained 1 point when they choose correctly and lost 4 points when they choose incorrectly. As the results, the use of a greater magnitude of punishment interfered in the learning of conditional relationships and in the emergence of untrained relationships: the performance of M-L participants was less accurate in the Symmetry and Relationship Maintenance Tests compared to other groups. This experiment extends the findings of other studies on the effect of punishment on discriminative learning and gives rise to a discussion about the use of punishment more intensely in learning.

The development of interconnected, digitized, autonomous and integrated processes in different parts of production systems has been supported by technological advances in Industry 4.0. Industry 4.0 encompasses a wide range of technologies, among which are technologies that support the generation and analysis of large volumes of data in real time, supported by technologies such as Big Data, Big Data Analytics (BDA) and Internet of Things (IoT), which support the search for operational improvements such as optimized flows and real-time anomaly identification. Similar goals are shared by operational improvement methodologies such as Six Sigma (SS) and Lean Six Sigma (LSS), which over the past 3 decades play an important role in process control and improvement following the DMAIC structured method and tools and techniques for data analysis. Technological advances from Industry 4.0 technologies can support and expand the resources of the SS methodology, making it possible to reach other levels of operational performance. To identify the main technologies of Industry 4.0 that can be integrated with the SS methodology, the main relationships and benefits and the future in this field of study, a Systematic Literature Review was carried out considering the Web of Science and Scopus databases. As a result, it was identified that the technologies that most support SS are Big Data, BDA and IoT and that the relationships presented that these technologies positively support data analysis and better decision-making in improvement projects. Considering the evidence of the relationship between the Six Sigma methodology and the BDA, the proposition of hypotheses and a theoretical model were developed with the aim of investigating through a survey of relationships between the practices of BDA, SS and quality and business performance. A survey was carried out with SS specialists from several Brazilian manufacturing companies, in a total of 171 founders. The proposed model and hypotheses were confirmed using the PLS SEM technique, showing that the BDA positively impacts SS practices and when integrated, it has a greater impact on improving quality and business performance.

Animals of medical interest are a public health problem that exist for a long period. The scholarship environment becomes an important factor for the ethical construction of the individual, through awareness of the information, and prevention of how to act in the face of an accident with those animals. The lack of knowledge or misinterpretation about these animals and the presence of myths and legends reveal that this theme deserves greater attention within schools. The main objective of this study is to carry out a critical analysis of the perspective, care, and understanding of science/biology teachers and 9th-grade students, on the issue related to accidents with animals of medical interest. This research was carried out from the qualitative analysis. The collection instrument was the questionnaires, that were made to verify the knowledge about animals of medical interest in the school, allowing the free expression of the respondents in closed and open questions. We concluded that students and teachers were able to relate animals and their dangers, and would have positive attitudes in the face of an accident. This work enables future research related to animals of medical interest, both in terms of teaching and teacher training.

The growing number of people suffering from overweight and obesity increases the demand for the development of intervention models for lifestyle adjustments based on the regulation of energy balance and adipose tissue metabolism. The study aimed to verify the influence of inperson and on-line intervention model on adipose tissue metabolic markers in obese women; 40 obese adult volunteers aged between 20 and 45 years will be selected, who will undergo 12 weeks of in-person and on-line multidisciplinary therapy with physical assessment, and collection of biological material for biochemical analysis, along with on-line support through emails, WhatsApp®, social media, and obesity-themed videos on an on-line platform (www.#12weeksfor, eat, fit, live). At the beginning and the end of the study, the volunteers performed a physical assessment of body composition, biochemical analyzes (glucose, adiponectin, leptin, and PAI-l). Volunteers could ask questions daily via email or WhatsApp® and received information about diet and exercise. The results were analyzed using SPSS software – version 22.0, for OS. Data normality was obtained using the Kolmogorov Smirnov test and expressed as mean and standard deviation (SD). To compare the means found between groups and intragroup, ANOVA Two Way and Fisher's post-hoc were applied, adopting the value of “p”, and thus verifying the significance found between the values. The dependence behavior of the variables was verified by simple linear regression. Based on the findings, it was possible to conclude that 12 weeks of in-person and on-line therapy can be widely used to combat obesity in this population, which reinforces that, even in a short space of time, significant changes can occur in all components of the body composition, as well as in the leptin, adiponectin and PAI-1 fractions. However, more studies need to be carried out to confirm in the long term and through a cut-off study that can cover a larger number of participants, thus fully elucidating and understanding the exact mechanisms that are involved in the weight loss process, changes in body composition, changes in leptin, adiponectin and PAI-1 fractions.

The removal of the microplastics glitter by fluxing results in its disposal in sewage treatment plants or deposition directly in aquatic ecosystems, enabling a broad interaction with biota. In this context, this study analyzed the photosynthetic rates (by the light and dark bottle method) of the submerged macrophyte Egeria densa in the presence of three concentrations of glitter: 0.0235 g (T1/T4), 0.0117 g (T2/T5) and 0.0058 g (T3/T6), as well in its absence (control treatment, CT1 and CT2). We tested 800 apical fragments of E. densa distributed in 8 subtreatments (4 under light conditions and 4 in the dark to obtain respiration) with 100 macrophyte fragment in each). The highest net photosynthesis rate (NP = gross photosynthetic (GP) rate subtracted from respiration (RD)) of E. densa was observed in the CT1, showing differences of 13.0%, 32.8% and 59.3% higher compared to T1, T2 and T3, respectively. Only the P N in T1 was not significant (p > 0.05) compared to the other glitter concentrations (T2 and T3). In T1, the highest mean respiration rate (RD) of E. densa was observed, and in T3, the lowest. The presence of glitter may have increased the reflectance, as it is a suspended particle, and resulted in the predominance of regular reflection, common in a well-polished metallic surface. The glitter reflects radiation decreasing the light absorption, altering the utilization of underwater radiation by E. densa. The larger amount of microplastics may result in the continuous reflection of radiation between the suspended glitter particles, allowing them to remain in the bottle, resulting in the higher NP in T1 compared to T3. However, it is considered that Egeria densa has a reduced distribution in places with intense sediment resuspension, and therefore it is assumed that in natural environments the photosynthetic response would be represented by T3. We concluded that the presence of glitter interferes with the absorption of light necessary for photosynthetic processes, reducing it, enabling an imbalance in the metabolism of the ecosystem.

The research aimed to identify and characterize the planting, production and water conservation projects implemented in the Atlantic Forest Biome of Minas Gerais and Espírito Santo in southeastern Brazil and in Catskills in New York in the United States, interrelating with the traditional and technical knowledge of the rural producers located in geographic territories where public policies for the management of water resources are implemented it. The inspiration for the conceptual bases and the theoretical framework adopted was based on timeless authors such as Thomas Khun and his reflections on Paradigm, as well as the reflection on Social Critical Theory of the Frankfurt School and on the School of Sociology of Knowledge by the Forte Program. The counterpoint of the authors and schools mentioned is confronted by Karl Popper's Falseability Theory. The method of study in multiple cases was used to research the projects: Conservador das Águas in Extrema-MG; Plantadores de Água in Alegre-ES; and the Catskills Watershed Corporation (CWC) in New York in the United States. The dissertation is characterized as qualitative research through participant observation techniques and through an ethnographic approach in the three case studies investigated in loco. The research was developed in four layers: 1) the theoretical magnifying glass, through bibliographical research; 2) the documental magnifying glass, through content analysis of institutional-legal records, maps and files that conceived the projects; 3) through the analytical listening of institutional actors, through scripted interviews recorded with the creators, formulators, managers and executors of the projects; and 4) by listening to rural producers and landowners, residents and tourists, through semi-structured interviews with project participants. Forty-nine interviews were conducted. The result presents a comparative table of findings and discoveries for the conservation of natural resources, guidelines to improve monitoring, expansion of communication, social participation and the governance arrangement implemented. The three researched projects have common aspects such as ecological sustainability, environmental education, and management of water resources in each territory and the challenges to overcome difficulties, for the continuous improvement necessary for the improvement of each project, considered forefront in environmental management both in Brazil and in the United States. Several outcomes point to more similarities than differences. The three projects develop actions for the revitalization of the watersheds.

Facing global climate challenges and the search for sustainable development, the creation of parks in urban areas has become a strategy to deal with these issues. Among the green areas of cities, the Urban Park is a category that has multiple benefits and functions. Therefore, instruments that aim for a better planning and management of these places are extremely relevant. Widely spread within the Conservation Units (UCs) context, the Management Plans aim to provide relevant information about the managed location, the zoning of the area, the rules of use, instructions for the management of natural resources, among other guidelines. In the city of São Paulo-SP, the “Master Plans for Municipal Urban Parks” also aim to delimit and provide fundamental guidelines for the management of these places. The mentioned contexts suggest that the search for relevant characteristics of these instruments can be useful in the construction of management documents for urban parks in general. Therefore, the objective of this research is to present subsidies for the elaboration of management instruments for urban parks. From the analysis of Methodological Guidelines for the Elaboration of Management Plans, proposed by ICMBio and by the São Paulo Environmental System, it was possible to list elements that could possibly guide the formulation of instruments focused in urban parks. Management Plans and Master Plans of Urban Parks in areas located in the city of São Paulo-SP were also analyzed and allowed the observation of factors that can be incorporated into the management of urban parks and aspects that can contribute to the development of similar instruments in other cities. The results obtained indicate that management instruments for urban parks should be designed and structured taking into account the characteristics of the area and its surroundings, promoting shared management, delimiting zones to ensure compatible uses, identifying programs and actions, defining administrative procedures and management, as well through constant monitoring to promote the adaptive management of these places.

In this Course Completion Work, we propose a reading of the novel O susto (1958), by Agustina Bessa-Luís, from the mobilization of aspects referring to the category of characters in order to understand the phenomenon of references of novelistic creatures to figures of Teixeira de Pascoaes and Fernando Pessoa. The main aim is to demonstrate in detail a narrative strategy of the author, in which external and latent traits and characteristics of the Portuguese canon are subtly introduced in the work in an allusion to two references of Portuguese poetry. This gives the novel some peculiarities with regard to the construction of characters characterized as artists. The Augustinian novel makes the textual limits of genre tenuous and intensifies the discussion about artistic creation itself, and its writing enables a metaliterary discussion about this process or even about the literature produced in Portugal in the 1950s. therefore, a reflection on the idea of the artist characters present in the work and the understanding of the art generated through them.

Bacteria associated with Paspalum plants can be employed as biofertilizers to increase the efficiency of pastures and reduce the use of agrochemicals by converting nutrients into an assimilable form for the host plant and defense against phytopathogens. In this context, silica nanoparticles (NPs) can be a tool to increase the effectiveness of biofertilizers in the field. This study aimed to isolate, identify and characterize the endophytic and rhizospheric microbiota of Paspalum spp. for plant growth promotion and to evaluate the effect of these bacterial isolates associated with silica NPs in Paspalum notatum seedlings. The bacteria were isolated from roots, leaves, and soils of P. rojasii, P. compressifolium, and P. lenticulare and tested in vitro for biological nitrogen fixation, phosphate solubilization, indole-3-acidic acid (IAA) production, and antagonism against the phytopathogenic fungi Claviceps purpurea and Fusarium oxysporum. The bacteria with biotechnological potential were identified by the 16S rDNA sequencing, and isolates of the genera Alcaligenes, Pseudomonas, Enterobacter, and Serratia were selected for the in vivo tests in P. notatum and Poa annua. The seeds were disinfected and inoculated with treatments composed of bacteria and bacteria + F. oxysporum and placed in magenta boxes containing substrate. The seedlings were evaluated for germination rate, root and shoot length, and root and shoot dry weight. Seeds submitted to the same treatments were plated in Petri dishes with 0.7% agarose, and the seedling roots were 3,3’-diaminobenzidine stained and visualized under an optical microscope. In another experiment, 85 nm silica NPs at concentrations of 0.05 mg/mL and 0.1 mg/mL were added to the culture media of Alcaligenes sp., Enterobacter sp., and Serratia sp. A total of 11 treatments were inoculated in disinfected seeds of P. notatum and subjected to the same conditions described previously. Out of 105 isolates, 26 solubilized phosphate, fixed nitrogen, and produced IAA. Serratia sp. and Enterobacter sp. inhibited the C. pupurea growth, but none of them was antagonistic to F. oxysporum. Serratia sp. promoted significant growth of P. notatum. F. oxysporum did not inhibit the development of the seedlings, and promoted the greatest plant growth when inoculated with Enterobacter sp. However, all the seedlings inoculated with F. oxysporum exhibited thin and fragile roots and shoots. The isolates belonging to the genus Pseudomonas promoted significant growth of Poa annua. Bacteria increased the number of root hairs, and it was possible to visualize intracellular bacterial colonization in the roots. In the second experiment, the three bacterial genera without the NPs promoted the growth of P. notatum. Total germination and the highest shoot dry weight were obtained in the treatments of 0.1 mg/mL silica NPs associated with Serratia sp. and Enterobacter sp. Silica NPs associated with the three bacteria increased root length and root dry weight. Bacterial isolates from Paspalum spp. with silica NPs showed potential to be applied as nano-biofertilizers and promote plant growth in P. notatum.

Postural control is important for independence in the daily activities of children and adolescents and is dependent on the interaction between the visual, somatosensory and vestibular systems. In addition, the sensory system modifies the efferent motor command, regulating the musculoskeletal system, to promote voluntary and automatic actions, modulating postural control according to the demands of the environment. However, individuals with cerebral palsy (CP), as a result of lesions in the central nervous system, have motor deficits and sensory information processing deficits, which impair postural control. In many everyday situations, in which sensory inputs are reduced, such as in low light conditions and without support for the upper limbs, there may be an exacerbation of the difficulty in postural control, thus increasing the risk of falls. In view of this, the motivation to develop a systematic review arose, in order to verify sensory manipulation and synthesize its influence on postural control, updatinganexistingsystematic review. Thus, a study was carried out, entitled ''Sensory manipulation and postural control in individuals with cerebral palsy: A systematic review''. It was found that sensory manipulation can facilitate postural control when an additional visual stimulus is used, or it can cause harm when sensory information is restricted/reduced, however, the included studies did not investigate how muscle activation patterns occur, in association with the behavior of the center of pressure, during the manipulation of different sensory information. After the finalization and interpretation of the review, gaps were noticed regarding the topic and the population of interest. In this way, study II was prepared, entitled ''Postural Control in conditions of task manipulation in children and adolescents with Cerebral Palsy'' emerged, in which typical and typical children and adolescents with CP were evaluated, in order to verify the effect of four conditions (open eye with support; open eye with out support; closed eye with support and closed eye without support) on postural sway, assessed by the displacement of the center of pressure, in orthostatism; and on muscle activation, assessed by RMS and co-contraction, of the lower limbs and trunk. The results showed that the group with CP presented greater postural sway than the typical group, in all conditions evaluated. Furthermore, in the evaluation of muscle activation, it is noted that the CP group uses different strategies than the typical group to maintain postural control. Thus, these studies contribute to rehabilitation professionals, leading to reflections on how to use the manipulation of task conditions both to facilitate and to challenge postural control, depending on the objective of the therapy.

Tri-reforming of methane (TRM) is a combination of steam and dry reforming and partial oxidation of methane reactions in the same reactor. Since it occurs at high temperatures and has water vapor in the reactor feed, TRM needs catalysts with thermal and hydrothermal stability, high oxygen storage capacity, resistance to carbon formation, and a high surface area. Aiming all these properties, Ni/SBA-15 catalysts promoted with CeO2, ZrO2, MgO, (CeZr)O2 were synthesized by two different synthesis methods: i) promoters impregnated on SBA-15 support which was already synthesized and calcined; ii) promoters incorporated into the SBA-15 structure during synthesis. The precursors were characterized with thermogravimetric and thermodifferential analysis, X-ray diffraction (XRD), nitrogen physisorption, temperature programmed reduction with hydrogen (TPR), temperature programmed desorption with carbon dioxide, scanning and transmission electron microscopy and X-ray photoelectron spectroscopy (XPS). The formation of the SBA-15 structure in all materials was confirmed by XRD analysis. Nevertheless, the incorporated catalysts presented a higher degree of ordering in the pores construction than in the impregnated ones. Through TPR and XPS analyses, it was verified the existence of a strong interaction between nickel and support, which is increased with the presence of promoters. The TRM catalytic tests were carried out at 750 °C for five hours, with reagents being fed into the reaction stoichiometry (3CH4:1CO2:1H2O:0.5O2). In this reaction condition, catalysts promoted with (CeZr)O2 and MgO showed the highest methane and carbon dioxide conversions. All catalysts were also subjected to TRM in water scarcity at 750 °C for five hours (3CH4:1CO2:0.1H2O:0.5O2). In this reaction atmosphere, there was an increase in carbon dioxide conversion and inhibition of methane conversion for all samples. Through thermogravimetric analysis, it was observed that the incorporated catalysts presented greater amounts of carbon depositions on their surface than in the impregnated ones. However, even generating more carbon in the incorporated ones, exhibited better stability during the five reaction hours.

The objective of this work was to avaliate the viability of canola (Brassica napus L.) in different municipalities in the Alto Paranapanema Basin through crop modelling. We used daily meteorological data of maximum and minimum temperatures (ºC), rainfall (mm) and global radiation (MJ.m-2.D-1) of ten municipalities in the region between 2009 to 2019 and, later, introduced in the DSSAT plataform to the determination of attainable productivity. Ten dates of sowing were simulated, spaced fifteen days, from February 15 to June 30, with the objective to understand the right sowing window of the canola in the Alto Paranapanema Basin. Finally, data was spatialised with Quantum Gis software (QGis 3.18). Even though these simulations are far from productivity indices of traditional countries in canola production, as Canada, at the national level the region can be an exponent of production, with average attainable productivity on the best sowing dates, between April 15 to 15 June, of 1.492,85 Kg.ha¹ and average standard deviation of 139,60. This shows the potential of canola in the Alto Paranapanema Basin region, and should therefore have investments to quantify and, subsequently, increase agricultural productivity.

The water management in the settlements of the brazilian Agrarian Reform is a topic of great relevance and always current, due to its complexity and developments. Amidst the current environmental crisis, therefore, debates about the importance and process of water scarcity are even more present. Recognizing the importance of water for domestic and productive uses, this work sought to describe the characteristics related to water supply and management in the SDP Sepé Tiaraju, by the own settlers, through their speeches. The study area is located on the recharge area of the Guarani aquifer, in the cities of Serra Azul and Serrana. The settlement is an example of agroecological production amid the highest concentration of sugarcane in Brazil. Questions about the sources of supply, distribution and uses of water in everyday life were adressed. To understand the experiences of farmers related about the water, qualitative and quantitative approaches were chosen, through the application of questionnaires and semi-structured interviews with 10 farmers from all nucleus of the settlement. Data analysis was performed based on the interdisciplinarity that the central theme requires. The results indicate that problems related to water supply and its multiple uses have existed for years on SDP, pointing to a situation of human and productive vulnerability over all the life cycles of the settlement, which goes against the construction of the guiding principles of the SDP modality: the construction of a rural settlement model, in which Agroecology is the center of the technological matrix. It is considered urgent the strengthening of public policies aimed at water supply for family farming, as well as basic sanitation in general.

Inside the 5G Core (5GC) a myriad of (virtual) functions may be deployed so that different treatment can be given for traffic coming in and out to/from the Radio Access Network (RAN). One of these key functions is Service Function Chaining (SFC) supported by SRv6 state-of-the-art protocol. In this work, we present an SFC P4-based solution for traffic identification and chaining using SRv6. We call this function In-Network Classification and chAining (INCA), which is deployed entirely in the data plane using a Netronome Agilo SmartNIC. The INCA is deployed just before the User Plane Function (UPF) inside the 5GC and is capable of observing the traffic coming from and going to the RAN so that it classifies and creates the proper sequence of services to be followed by every specific flow. Our results show that INCA performs the task of packet classification and chaining perfectly with a minimal Flow Completion Time (FCT) impact when compared to the same environment without it.
