Lean manufacturing continues to be widespread in the business world as a management philosophy to reduce waste. Despite this, the sustainability of the results of lean initiatives has proved difficult to achieve. There is a limitation on the part of organizations in understanding the factors that influence lean sustainability in all organizational environments. In this direction, the objective of the research was to identify the critical factors for manufacturing companies to sustain their Lean initiatives over time. For this the mixed research method was used, combining the systematic review of the literature, case study and expert opinions. In the systematic review, articles were filtered in scientific journals: Scopus, Engineering Village, Proquest and Web of Science in order to identify in the literature the factors mentioned as critical to sustain lean. Thus, combining the review with snowball methods and expert opinion, we obtained a list of 21 factors. This list was analyzed in the case study with two industries for refinement of the list. Finally, the list of factors passed by the analysis of 5 experts, in the end 19 factors were considered as critical. The results achieved contribute to the professionals have a vision of what aspects should be addressed throughout the Lean journey. In the academic context, the contribution was to compile the lean sustainability factors that are spread in the literature and to show which ones should be explored.

Ferroelectrics are material exhibiting a spontaneous polarization that may be switched by an electric external field. This behavior is provided to well-known ferroelectric domain walls motion. Recent research has proved the surprising ability to move ferroelectric domain wall under illumination with wavelength of 532 nm incident on a surface of single crystals of Barium Titanate (BaTiO3). In spite of experimental results concerning about this light-matter interaction, it is remarkable a lack of physical insight, as well as possibility to observe if occurrences of motion domain wall is due to single or poly crystal character. By using a phenomenological approaches based on Devonshire-Landau’s theory was possible make a development to describe a polarization-induced switching under light like perturbation of bound and free charge accumulated within domain wall. Accordingly, interactions between photons having lower energy that optical gap and screening charge give rise to fluctuation in depolarization electric field that serve as a driving force to polarization reorientation around the wall. This approach gives a satisfactory explanation to experimental facts observed in single crystals of BaTiO3, in addition, it allows to conjecture a correlation between the phenomenon occurrence with existence of charged domain wall as single crystal as polycrystal. It was prove that BaTiO3 coarse grain ceramics (grain size approx 50µm) contend 90-domains are possible a manifestation of polarization switching induced by light also, in this form, it was demonstrate the size grain dependence with evidence of this light-matter interaction, highlighted again the role-play of charged ferroelectric domain wall. In this way, here has made an extend to polycrystal materials that could lead to developed the next generation of photo-stimulated ferroelectric devices.

This work describes the development of electrochemical immunoassays using electrode disposable devices made from low cost materials as an alternative for detection of the biomarkers p16, GSTP1, PSA and CYFRA-21-1 for prostate cancer diagnosis. In the immunoassays developed, magnetic micro/nanoparticles were used in order to provide the capture and separation of the biomarker and the amplification of the analytical signal allowing to reach high selectivity and low limits of detection. For this propose, disposable microfluidic cell was developed and constructed containing 8 carbon-based working electrodes, an Ag|AgCl electrode as a pseudo reference electrode and a carbon electrode as an auxiliary electrode. Three different immunoassays were developed. The first work consisted in the development of an electrochemical immunoassay for the detection of the p16 biomarker. Immunoassays were performed after optimization of the parameters, such as incubation time and flow rate used in the microfluidic system. The calibration curve was prepared in calf serum with p16 concentration in the range of 1.38 to 27.7 fg mL-1. The device presented detection limit (LoD) of 0.04 fgmL-1 and sensitivity of 11.6 nA (fg/mL)-1. The second method consisted of the simultaneous detection of PSA and GSTP1 biomarkers. Peak currents obtained showed a linear response between 0.7 - 27.8 fg mL-1 for GSTP1 and 0.28-277 fg mL-1 for PSA. The sensitivities reached for GSTP1 and PSA were 22.4 nA (fg/mL)-1 for both biomarkers and the LoDs were of 0.15 fg mL-1 for GSTP1 and 0.16 fg mL-1 for the PSA. Finally, the third immunoassay consisted of the application of synthetic nanoparticles (MNPs) of Co0.25Zn0.75Fe2O4 (CoZnFeONPs) and Fe3O4 (FeONPs) used to mimic the enzyme peroxidase. The use of modified carbon work with graphene oxide (GO) and MNPs allowed the electrochemical detection of CYFRA-21-1 with LoDs of 0.30 fg mL-1 and 0.19 fg mL-1 for FeONPs and CoZnFeONPs, respectively. Finally, it was possible to test the immunosensor in serum of patients provided by the Hospital de Amor from Barretos city obtaining concordant results with ELISA method, which showed that the device is a promising choice for diagnosis of prostate cancer in relation to traditional methods as ECL and ELISA.

The understanding of autism, currently known as Autism Spectrum Disorder (ASD), has undergone several changes over the years. In the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), in 1980, came the inclusion of autism as Pervasive Developmental Disorders (PDD). However, in the tenth revision from the International Classification of Diseases (ICD-10) from the World Health Organization (1992), it included childhood autism inside the global developmental disorders group. At the DSM-IV (1994), in addition to autism, was the inclusion of the Asperger syndrome and Pervasive developmental disorder not otherwise specified, and, in the fifth and latest version (DSM-V), from 2013, the denomination used was "autism spectrum disorder"; besides changing the denomination, occurred the modification in the structure of symptoms and signs group that determinates the diagnosis of ASD. In Brazil, philanthropic institutions within social services or autistic family associations are often responsible for the care of these children with autism. Some studies show that this late development caused the elaboration of the public policy for autism to be marked by two opposing groups: the group linked to the actions from the psychosocial attention related to the public policy of the unified health system (SUS), and the group associations of parents and family members of autistic people. With SUS public policies, were created the Child and Youth Psychosocial Care Centers (CAPSij) with the perspective of territorial health and articulation with the Psychosocial Care Network (RAPS). Recent studies address the difficulties encountered in these CAPSij concerning strategies and actions aimed at these children and adolescents with autism, highlighting the need for research to assist in the identification and understanding of the demands that reach these services. The current study aimed to characterize people with autism-linked to a CAPSij in a town in the state of São Paulo. It is an exploratory research of a quantitative approach that involved the participation of managers from all four Child and Youth Psychosocial Care Centers (CAPSij) from a town in the state of São Paulo. For data collection, modules of a structured interview script were used, elaborated in the broader research to which this TCC is linked, and a medical record data record form, elaborated in this study. It revealed that 26% of the CAPSij patients were autists, with a prevalence of reach between 1 and 5 years old, mostly males. The study also identified some weaknesses in the engagement of adolescents with ASD in these services. In general, the results achieved revealed fragilities resulting from the team composition in CAPSij, that should impact the care practices and actions related to ASD in particular.

The water crisis is a hotly debated issue in recent years, especially as regards the effects of globalization, both on the interference of climate change directly on recharge and on the disorderly increase of the urban environment that directly affects the availability of water for domestic consumption, and industrial. These climate changes alter pluviometric regimes and volumes, evapotranspiration, the recharge process of aquifers, and river flows. Deforestation and paving of recharge areas are the result of urbanization and the advancement of agricultural production, leading to increased waterproofing of the soil and thus affecting the infiltration and storage of groundwater. The objective was to fill some gaps in the literature, in relation to the studies that investigate the water refills, using a bibliometric mapping and geological-geotechnical detail mapping, aiming the monitoring of water recharge zones in the region north of the municipality of São Carlos, SP. In order to do so, the monitoring of free aquifer of the microbasin was carried out by means of frequent measurements of the static levels of 4 monitoring wells for the subsequent application of the Water Tabel Fluctuation (WTF) method that verified an annual recharge of 1338.8mm, lower value to the previous years, representing an average of 16-36% of all direct annual recharge of the microbasin. In addition, a multitemporal analysis of the soil cover type was done in this study, demonstrating the problems generated by the increase of the percentage of soil exposed in regions of springs, increasing, consequently, the surface runoff and reducing the infiltration. It is concluded that the monitoring of the recharge of water has been satisfactory and that stricter measures in the management of water resources must be taken so that future generations do not suffer from water crises in the region. In addition, urban sprawl in the study area may directly interfere with this decrease in surface recharge.

Since the emergence of recyclable waste pickers’ organizations in the 1990s, these organizations have been responsible for helping in closing the gap left by the public service in waste collection and sorting. Despite the representativeness of the activities developed by these cooperatives and associations in terms of environmental and social aspects, few efforts are made by the public service to provide better facilities, equipment and working conditions to these organizations. This research is focused on the challenges faced for the structuring of waste pickers’ organizations so that they can develop their activities considering productive efficiency and health criteria. In this setting, this research is framed by the following question: how can one incorporate the real work of operators in the technological decisions of waste pickers’ cooperatives? From this question, the goal of this research was to investigate the origins and uses of technologies in collectors’ cooperatives to develop approaches to support the incorporation of the activity in the technological decisions in waste pickers’ cooperatives. Two case studies in two cooperatives were conducted following the theoretical standpoint of the Activity Ergonomics, in which emphasis is placed in the distance between the task and the activity. In this stage the main focus of observations were the artifacts and instruments used materials handling and the facilities, aiming to achieve a better understanding on how the facilities and artifacts were planned and acquired, how the technological adaptations were carried out and workers’ usage of these resources in daily operations. The data show that due to the lack of participation on technological decisions, cooperatives need to adequate spaces, flows and workstations, besides using improvised artifacts as a way to achieve production goals. As outcomes from these aspects and focusing on the technological decisions associated to the facilities and artifacts were developed: a diagnosis tool for decisions planning that enables waste pickers’ organizations to understand their current and future development stages and an articulation between the activity-centered approach and participatory design approaches that enable not only the analysis of the current activity, but also the incorporation of the activity in future work systems design by means of collective decision processes. Furthermore, the structuring of waste pickers’ organizations must be aligned with the demands and specificities of these organizations. In addition, the understanding of the work actually performed at these enterprises and the participation of the involved actors in the decision processes ate the main requirements of the technological decision process.

O artigo revisa a literatura da sociologia econômica, área que alcançou rápida institucionalização a partir do diálogo crítico com a economia neoclássica. Considerando a importância que a área conquistou e a ausência de levantamento bibliográfico no Brasil sobre a produção nos Estados Unidos, o objetivo deste artigo é construir um “estado da arte” da sociologia econômica produzida nesse país, identificando os principais autores, ferramentas teóricas e debates. Argumentamos que a área se constituiu em torno do conceito de enraizamento, utilizado por Karl Polanyi e recuperado por Mark Granovetter, e que inspira direta ou indiretamente autores e organiza os debates do campo.

Bag-of-Tasks (BoT) applications are parallel applications composed of independent (i.e., embarrassingly parallel) tasks, which do not communicate with each other, may depend upon one or more input files, and can be executed in any order. BoT applications are very frequent in several scientific areas, and it is the ideal application class for execution on large distributed computing systems composed of hundreds to many thousands of computational resources. This paper focusses on the scalability of BoT applications running on large heterogeneous distributed computing systems organized as a master-slave platform. The results demonstrate that heterogeneous master-slave platforms can achieve higher scalability than homogeneous platforms for the execution of BoT applications, when the computational power of individual nodes in the homogeneous platform is fixed. However, when individual nodes of the homogeneous platform can scale-up, experiments show that master-slave platforms can achieve near linear speedups.

This research aims to analyze, through the comparative method, the process of insertion of Brazilian transvestites and transsexuals into audiovisual pornographic production. It was decided to work with two distinct moments: the beginning of this type of production in Brazil during the 1980s in the context of the explicit cinematographic production of boca do lixo paulistana, and in its more contemporary phase guided by a context of production, distribution and consumption mediated by digital technologies. So, in the second moment, we chose to work with some specific sites: I) the websites that make up pornographic distribution conglomerate Pornhub Network (specifically, the most accessed platforms such as pornhub.com and redtube.com) and II) the site specialized in pornography with transsexuals Shemale Tube (ashemaletube.com). All of these platforms have as characteristics the distribution of their contents for free, which favors the increase in their access and search flows. Based on a bibliographical and documentary research on aspects of pornographic production in modernity, we intend to investigate how the body of Brazilian transvestites and transsexuals appears within the audiovisual pornographic tradition.
“Papagaio velho não pega língua mais, não”: estuciando o jeito de falar e de fazer, o jeito de ser, no quilombo Córrego do Narciso do Meio, Vale do Jequitinhonha (MG)

Córrego do Narciso is a rural quilombola community near Araçuaí, in the semiarid north-eastern Minas Gerais, in the Jequitinhonha Valley. In face a historical effacement of the term quilombo in the region, a quilombola reidentification by subjects occurred since 2009. If attention is also drawn to the institutional dimensions of struggles for example for water, underlying or subterranean dimensions appear in view of the apprehension of components of the collective memory in the community, in which water and the dimensions of life, death and enchantment are merged. Categories thus merged and imbricated, and mobilized in a mobile and contingent manner, are understood more in terms of what Stuart Hall understands as an articulation, open and in movement - in what also allows us to think identifications, in their fluidity and openness -, than from a reading of habitus which may conduce to a closing of identities. If there are differences between both interpretations or comprehensions, there are nonetheless approximations, as for instance in the materialist presupposition. A descentering of subjects, which appears empirically in mediated and collective practices and conceptions of agency, is propitiated, at a theoretical level, by that concept of articulation, conferring more lightness - and less substance - to the social tissue. It is thus that are interlaced, in the text, porous and consubstantial categories of experience, such as past, present and future, race, gender, class and generation, campesinity, amerindian and negro-banto, city and roça (country), water, earth and food, life and death, moral, ancestrality and matrifocality. As an objective and a leading thread, the comprehension of subjects, in their processuality of des-re-identifications, is taken as a temporary heuristic device, which also, along the research, gives rise to a certain rarefaction of the research object, now intermingled with those other and also contingent categories. Adopting methodologies of oral history, of memory apprehension, the making of drawings and maps (on paper and on earth) by subjects of different generations, the course through memory sites and the observation and analysis of ethnographic situations, the question of the subject is taken in a sufficiently open manner as to allow its unfolding and ramification in that multiplicity of questions and themes. The leading thread of the text is, therefore, the stories, memories, accounts, narratives and activities that I could listen, observe and register of inhabitants of Córrego Narciso, apprehended in a non-restrictive and non-linear manner. Estuciar, a term which composes an expanded repertoire of a rural dialect specific to the region, as an inflexion of astuciar (cunning, astuteness, artfulness), designates that vitality of a real-ficcional production-invention of the everyday practices and knowledge in Córrego Narciso. An ambivalence of de-materialization or de-structuration characterizes fantastic and enchantment components of practices directly referred to life - such as birth at home, the cultivation of manioc, the treatment of diseases and language -, in which there would be a suspension of material-normative constrainments. Estuciar denotes these experimentations, representations, improvisations and inventivities in the forms of speaking, of doing and of identifying. The quilombola reidentification is accepted and assumed, sometimes firmly, but in the subjects own terms, in such a way that maintains components of a being that is prior to that new identification, in a way in which the subjects avoid being deceived or misled, maintaining their speech forms. There is not an unconditional subscription to the institutional and instrumental logics of the should-be, but a recognition signified also as want-te-be and can-be. Thence the new political and hybrid subject that is forged is not that new. Such reidentifications are encompassed in a multiplicity of other identifications.

La présente thèse couvre l'ensemble des écrits de Michel Foucault du début des années 1970 à 1984 afin d'enquêter sur les déplacements subis par l'articulation entre le pouvoir, les luttes politiques et la Révolution. Nous essayons d’abord de montrer comment cette triple articulation se déroule à partir du contexte gauchiste de Michel Foucault et de l’élaboration de son analytique du pouvoir, encore configurée en termes de dynastique du savoir. En ce sens, nous essayons de montrer comment la période dynastique correspond à un schéma théorique de la conceptualisation du pouvoir, nettement développé en opposition au marxisme. Cela contraste avec le refus du système d'infra-superstructure marxiste et du modèle contractualiste (hobbesien) de l'État. Deuxièmement, nous visons à comprendre en quoi la reformulation de l’analyse du pouvoir depuis 1976 est fondamentale pour une critique de la notion de révolution et pour une analyse des luttes politiques autour des notions de "contre-conduite", de "l'indocilité réfléchie" et de "spiritualité politique". À partir de 1978, l’analyse du pouvoir est reconfigurée, ouvrant un espace au concept de gouvernementalité. Cette nouvelle configuration pose de nouveaux problèmes à la résistance au pouvoir et à la compréhension de la transformation de soi et du monde. Enfin, nous traitons de la façon dont le concept de révolution réapparait dans les recherches de Foucault des années 1980 à partir des notions de "vie militante" et de "conversion". A partir de cette période, la notion de gouvernement permet de penser à la notion de révolution et, par conséquent, de "subjectivité révolutionnaire", à ses effets historico-philosophiques dans la perspective d'une constitution du sujet.

This work is an unpublished survey on the analysis of the use of a prestressed concrete constructional system with greased corbels in smooth slabs in multi - storey buildings in Brazil, according to the new norm NBR 6118: 2014. It is a critical study with the focus of market exemption on the processes of structural execution and the impact they cause on the cost of the structure. The studies developed so far, in the structural aspect, were made with norms prior to this one, which considers the quality of the structure and the durability beyond the safety conditions that are followed by all the offices of projects of the country. In relation to the study of the constructive processes there are only until then, studies done by companies involved in the procedures and, therefore, possibly without the necessary exemption for a critical judgment. Also, the studies done so far are extremely watertight without raising the project (structural calculation) and the cost of execution (processes and inputs) in detail. There are studies in which only indices of materials (concrete, steel and shape) are established, others that deal with the structural behavior of massive slab, ribbed lattice and ribbed with plastic vats and the conventional structural system (consisting of massive slabs and beams) with that of plain, massive or ribbed slabs, and finally a study that studies comparatively the costs between conventional structural systems and the structural systems of ribbed slabs in reinforced concrete. In this paper we try to understand the differences that exist when one opts for the adoption of the system of flat slabs for multi-storey buildings in detriment to the conventional one. Thus, it is analyzed from the phase of the structural project (what influences the execution and what the main knowledge that must be added to the detailing process), the one of execution, mainly focusing on the question of quantity of service and finally quantifying the cost of a same building executed in the region of Ribeirão Preto considering the conventional systems and the same with prestress slab. As a parameter of analysis to make these simulations, surveys of works in the country and in the region of Ribeirão Preto, interviews between actors involved in the process and bibliographic research were done. It can be concluded that, even in the case of usual buildings (medium size, buildings with usual plant architecture), this type of application can economically and without many technical difficulties be applied in several regions of the country, especially in Ribeirão Preto.

This work is situated within the sociology of prisons field. More specifically, in the process of apprehending and updating studies on the effects of the prison system on certain groups of society, prison. The object of interest is the so-called "vila", a group of houses destined to the managers of the Campinas-Hortolândia penitentiary complex, in the interior of the State of São Paulo. Located less than 60 meters from the prison walls, this work intends to observe and analyze micro-relations between residents and former residents of this locality and how prison contributes to the organization of their daily lives. In keeping with the changes in the public policies of the prison system in São Paulo, such as the expansion of prisons, its control by the criminal factions and the war on drugs, this work sought to understand how these issues were managed by this group in the search for strategies of maintaining the normality of social relations established in this place. Through interviews and the reconstruction of the collective memory of the group, it was possible to perceive that the influence of the prison generates not only a change in the discourse about the insecurity in the conscious plane, but also a deep process of subjectivation of the prison logic, reorganizing the strategies for guarantee cohesion and solidarity of the group. Through a symbiotic (between prison and village) and conflicting process, the relationships observed were shown as a constant effort by families to reinforce and re- signify the elements family and community institution, through adaptations that react to daily prison. These adaptations are incorporated into the everyday and normalized, becoming no longer objects of disruption of order, but rather elements that are part of the constitution of the community itself. Neither inside nor outside, but through prison, the village makes possible a sui generis community, an exacerbation of the influence of the prison in the groups in which it transforms. In it, the distinctions between public and private are weakened, as the solidarity between members strengthens. This causes, as I have tried to demonstrate, a community with a high degree of interdependence, which results in an odd, detached behavior of the broader society. It was also possible to observe the dilemmas and the great difficulty of the adaptation of these families to social contact, especially at the moment when they disengaged from their positions and closed the connections with the village community.

The formation of Brazilian culture was strongly influenced by the African peoples and one of the contributions of these habits, customs and traditions was the games that these peoples brought to Brazil. Through games human beings have created cultural and social conditions of learning to play. We believe that the importance of African culture is especially evident in the formation of the Brazilian people, especially when we talk about education, inheritance, traditions are the result of the influences of each culture. In this sense, the objective of this work is to identify the games coming from the countries of African students enrolled in the Federal University of São Carlos (UFSCar) and relate them to the African games in the literature. We used qualitative research as a method of work through the interview. The data collection was performed by an instrument called script, which served as a guide. The testimonies collected were recorded, transcribed and analyzed. As a specific objective, this work intends to contribute to processes of significant changes in our Brazilian society, such as recognizing and respecting different cultures, sharing the cultural wealth of Africa and making available the contents of games of African origin so that they can serve as a subsidy for the work of other educators. As a result, it was observed that African games are also part of the games played by people of different age groups in Brazil. It is also noticed that the playful is a theme full of consensus and conflicts in the field of education.

Information pertaining to water consumption per capita can be considered as a valuable tool for the design of parts of the water supply system of a municipality. The difficulty to the urban infrastructure designer is the estimation of the average per capita water consumption to be adopted in a water supply system project. The general objective of this work was to evaluate the physical and locational characteristics of urban lots and to correlate them with the effective per capita consumption of water for the city of Bebedouro (SP). We analyzed 37 neighborhoods, all with 100% hydrometric and occupancy rate equal to or greater than 85%. From the analyzed data, it was verified that the average effective consumption per capita maintained a positive correlation with the average individual income, not being, however, observed a relation of the consumption with the gross population density related to the occupied area. It was observed that the water loss in distribution was 57.25% in the year 2015. Hypothesis test indicated that the independent variables Average Lot Area (AML), Standard Unit Value and Maximum Standard Unit Value (VUP / VUPmax) and of the number of inhabitants per link of water / lot (NHL) presented a linear correlation with the average daily effective consumption (qe), for interval and 95% confidence. The equation was determined from regression of multiple variables with determination coefficient R2 = 0.8099.

The quality of pedestrian-oriented urban spaces is fundamental for economic development, public health, social welfare and environmental sustainability of a municipality. Many researchers base their studies on structural analysis of sidewalks and audits of spaces, considering aspects related to the safety, security, and attractiveness of the environment. However, there is a lack of studies that correlate characteristics of urban land use and occupation, as well as sociodemographic characteristics for the identification of urban spaces that are a priority to the focus on pedestrian. With the prioritization, the public management can identify punctually where to act to carry out studies, bring significant improvements to the walkability and choose, among the areas of the municipality, those that need more attention. Thus, the present study aims to develop a method that, based on the correlation of land use and socio-demographic variables, indicates such priority areas, named as Areas of Special Pedestrian Interest (AIEP), that is, priority areas for future analyzes and improvements related to the quality of pedestrianized urban space. The following steps are developed in the study: (i) selection of relevant variables, (ii) ranking variables according to hierarchical process analysis (AHP) in expert research, (iii) representation of results in GIS platform, (iv) identification of the AEIPs and (v) analyzing the walkability in selected zones. For the development of the method, the city of São Carlos (SP) is used as a study area because of the availability and ease of data collection, but it is expected that the method will be replicable in other scenarios. The results indicate about 1522ha of the urban region (19%) as (AEIP), extrapolating the consolidated urban center. Several "center of neighborhoods" regions are identified, presenting mixed occupation profile (residential, commercial and service uses). These areas are synthesized in 79 priority census tracts, encompassing about 60,000 inhabitants (27.1% of the population) and 50 km of road extension - highlighting roads of great structural, commercial and circulation importance to the municipality. The developed method was able to identify priority areas (AEIPs), correlating land use and socio-demographic characteristics and presenting guidelines for regions that need more attention in the pedestrian area and contributing to the management of municipal walking mobility.

Alternative practices in food production, which take into account the ecological sustainability of agroecosystems and the economic sustainability of farmers, are being increasingly tried and recommended. The objective of this work was to study the effects of green manure, Trichoderma asperellum and homeopathy on the agronomic performance and fruit quality of the “biquinho” pepper (Capsicum chinense Jacq.). The design was in a randomized complete block with four replications, in subdivided plots, the plot being two homeopathic preparations: 1) Arnica montana 6CH; 2) Pulsatilla nigricans 6CH; and control treatment, and the subplot 7 treatments: 1) Crotalaria juncea sown 50 days before the transplanting of the pepper plants, in the density 25 kg ha-1, managed at 50 days after sowing and regrowth at 91 days; 2) Crotalaria juncea sown 50 days before the transplanting of the peppers, in the density 50 kg ha-1 handled at 50 days after sowing and regrowth at 91 days; 3) Crotalaria juncea sown concomitant to pepper transplant in density 50 kg ha-1, handled at 59 days; 4) Canavalia ensiformis, seeded concomitant with peppermint transplant, density 25 kg ha-1, handled at 48 days; 5) Cajanus cajan, seeded concomitant with pepper transplant, density 25 kg ha-1, handled at 76 days; 6) Trichoderma asperellum inoculated in two moments; and 7) Control 2 (single crop). It was evaluated the height, stem diameter, relative chlorophyll index and normalized difference vegetation index (NDVI) of the pepper plants, production components fruit quality, and sensory analysis. There was interaction between homeopathic preparations and green manures/T. asperellum, which influenced the characteristics of the pepper plants, and there was also interaction between the for all variables analyzed (height, diameter, NDVI, IRC). Biometric values and fruit quality components were only influenced by green manures/T . asperellum, except the number of locules that altered according to the homeopathic preparation used. In sensory analysis there was significant difference only for fruit size, but this did not influence preference. The homeopathic preparations Arnica montana and Pulsatilla nigricans 6CH influenced the biometric characteristics of the pepper plants: height, stem diameter, normalized difference vegetation index (NDVI) and relative chlorophyll index (IRC). T. asperellum exerted influence showing some of the best results on the biometric characteristics of the pepper plants, and when associated with the application of the homeopathic preparation Arnica montana 6CH provided higher heights of plants and IRC. As for production, this did not differ from control. It was concluded that the 50 kg ha-1 intercropping with Crotalaria juncea seedlings sown 50 days before the transplanting of the pepper allowed a good development of the baguier pepper, with production similar to the control, fruits with better pH values, soluble solids, acidity and maturation index.

In this work, an investigation through experimentation and mathematical modeling was carried out with the intention of evaluating the drying process of pitangueira (Eugenia uniflora L.) and olive tree (Olea europaea L.) leaves in a conveyor belt drier, aiming the extraction of extracts by the supercritical carbon dioxide extraction. A complete characterization of both leaves as to their physical properties, such as characteristic dimensions, specific mass, initial moisture content, equilibrium moisture and surface morphology was performed. The results indicated that the leaves had distinct physical characteristics, with surface areas of 24 ± 1 and 8 ± 1 cm² for pitangueira and olive leaves, respectively. In relation to the morphology, the leaves of pitangueira present striated trichomes while the olive leaves have peltate trichomes. Drying tests were performed at temperatures of 50, 60 and 70 ° C using a forced convection oven and a pilot scale dryer. In the oven drying it was observed that the temperature has a significant influence on the drying of the leaves and that the internal mass transfer mechanisms control the drying process. In addition, the morphological differences of the leaves impose different resistance to the mass transfer during the drying process and the olive leaves have a more pronounced rolling than the pitangueira leaves. In the drying on the conveyor belt, in all the conditions imposed, leaves with discharge humidity were obtained within the range considered ideal for the supercritical extraction process (7 to 18% b.u.). The behavior of the drying kinetics was similar to that of the oven, and the peltate trichomes present in the olive leaves contribute to the increase of resistance to mass transfer in comparison to the leaves of pitangueira. The two-phase model accurately predicted the discharge moisture and temperature of the leaves during drying in the conveyor belt dryer. In the supercritical extraction tests, preliminary studies showed that the condition of 80 ° C and 250 bar is the most adequate condition to obtain the supercritical extracts of the pitanga leaves, presenting higher yields and higher extraction rates. The models of Sovová (1994) and Spline provided good agreements with the experimental data of the overall extraction curves in all conditions investigated. Drying had a significant influence on the extraction yields, as well as on the concentration of phenolic compounds and on the values of antioxidant activity for both leaves. In the case of the pitangueira leaves, the condition determined as the most appropriate was the drying done at 60 ° C and 60 minutes, since higher yields, phenolic compound concentrations and antioxidant activity values were obtained. In addition, in this condition also the lowest energy expenditure for the removal of moisture was reached. In the case of olive leaves, the best drying condition was 50 ° C and 180 minutes for the extraction yield and 60 ° C and 120 minutes for the concentration of phenolic compounds and antioxidant activity, showing that the drying conditions are very important in extraction of bioactive compounds via supercritical dioxide carbon extraction.

This thesis analyzed road safety of urban stretches of Brazilian federal highways, in an evaluation that involved the verification of occurrence of victims of crashes together with geometric conditions, signaling and pavement of the highways, and characteristics of urban areas. For the development of this work, accident records by the Federal Highway Police (PRF), and data on pavement, geometry and traffic signaling conditions, according to the methodology of the National Transportation Confederation (CNT), were used. Concepts based on the Safe System approach were utilized for the delimitation of accidents, which considers that traffic accidents, when they occur, should not cause serious or fatal victims. In the states of Paraná and Santa Catarina there were, in absolute numbers per state, the highest numbers of victims between 2010 and 2014. Espírito Santo presented the worst rates of injured and fatal victims per 100,000 inhabitants and per 10,000 vehicles, while Amazonas and São Paulo had the best performances. Throughout Brazil, 3,178 federal highway segments were found in urban areas with the occurrence of at least one seriously injured or fatal victim. The 64 most critical stretches were identified. It was found that most of these critical segments are in large urban areas, and many were in very good condition. This result demonstrates that other variables, such as composition and volume of traffic, can contribute decisively to the most serious accidents. By means of a proportional stratified sample of 118 stretches, a primary relation was found between the number of victims and stretches with regular road infrastructure conditions inserted in urban centers with greater area of influence and high Municipal Human Development Index (MHDI). The Poisson regression showed higher values of the Prevalence Ratio (PR) for poor road sign, good geometry and regular pavement, in the disaggregated analysis of road factors.

Tri-reforming reaction is a new method to use and convert CO2 from industrial plants effluents. The tri-reforming involved reactions are two endothermic reactions, the steam and dry reforming and the partial methane oxidation that is an exothermic reaction. Natural gas as a feedstock to tri-reforming is an alternative to use CO2, a H2O e o O2 without any separation process. Find new materials and improve the existents catalysts that are stable during the temperature oscillations and the comprehension of active catalysts during the tri-reforming reaction are relevant. Ni catalysts are the most used in reforming reactions. However, it has low thermal and mechanic stability and as a consequence are deactivated. Looking to this way the focus of this research is to obtain Ni catalysts supported in ZrO2 and CeO2, synthesized by unusual routes owing an improvement of supports to enhance the catalytic performance of Ni. The catalysts were characterized by XRD, N2 physisorption, TPR-H2, TPD-CO2, TPD-NH3, FTIR, TGA, TEM and SEM. The catalytic performance was analyzed using the tri-reforming reaction, measuring the CH4 and CO2 and the syngas formed. The first thesis core is the ionic liquid synthesis which the objective was synthesize the organic materials. The ionic liquids were synthesized using solvothermal route and were characterized by DSC, MNR 1H and 13C, CHN elementary analysis and FTIR. The second has as objective synthesize zirconium polymorphous, in which monoclinic and tetragonal phases were obtained by ionothermal route. After analyze the synthesis conditions influence in the support phases, then nickel catalysts were synthesized by wet impregnation. TPR-H2 were performed to understand the influence of zirconium polymorphous in the Ni dispersion. In situ characterization were used to investigate the transitions states and the catalysts stability in the reaction atmosphere. According to the ionic liquid composition in the support synthesis the tetragonal ZrO2 phase stabilization occurs and an improvement in Ni dispersion was observed which improved the catalytic performance of Ni/ZrO2 catalysts. The third thesis core refers to CeO2 and Ni/CeO2 synthesis and characterization and the analysis of catalytic performance of these materials. We analyzed the influence of synthesis conditions in the CeO2 support formation. The Ni/CeO2 catalysts were obtained by wet impregnation. TPR-H2 measurements showed different Ni dispersion according with the CeO2 supports synthesized even any phase transitions were detected by XRD. In situ characterization showed different stability according to the catalysts tested and the reaction atmosphere. In the last chapter the catalysts used in this research was compared each other. For both, Ni/ZrO2 a Ni/CeO2, the support synthesis route has influence in the metal dispersion and metal crystallite size. The catalytic performance was different according synthesis route and independently of basicity and oxygen vacancies of the support used, in tri-reforming reaction the most important variable is Ni0 crystallite size.
