    The Black Lion Tamarin, Leontopithecus chrysopygus, is a primate species endemic to the State of São Paulo and considered State environmental patrimony. It is on the international red list of species in the category "Endangered", mainly due to loss and fragmentation of its habitat. Roads cause direct negative impacts to wildlife, such as road kill mortality and the barrier effect. Wildlife crossing structures are implanted as a form of mitigation for both trampling and barrier effect, and canopy bridges are specific structures for semi-arboreal and arboreal species, such as primates. The aim of this study was to implement two "canopy bridges" fauna passages with distinctive designs in the Vicinal Domiciano de Souza road, GRI 253, Guareí-SP, in the crossing and trampling of black tamarin individuals, and involve the local community in protecting biodiversity. The fauna passages were installed in February 2017 and monitored for 13 months continuously, allowing the verification of functionality, use preference analysis and identification of the period of adaptation to the new structures inserted in the habitat. During the period of execution of the work, scientific dissemination actions were carried out in which information about biodiversity and local problems was shared with the purpose of sensitizing and engaging the community, thus promoting the formation of biodiversity conservation agents.

    Resveratrol (3,5,4 'trihydroxystilbene) is a polyphenol found in some plants and fruits that has been suggested as a preventive agent for the bone damage characteristic of osteoporosis. Studies indicate the effects on only a few bone parameters, besides diverging regarding the minimum protocol duration required to observe such effects. The objective of this study was to evaluate the effects of the treatment with resveratrol on femurs and vertebrae of ovariectomized young adult female rats during 60 and 90 days. Fifty-nine Wistar female rats at 3 months of age at the beginning of the experiment have been utilized, which were divided into 6 groups: groups maintained Intact for 60 and 90 days (INT 60 and INT 90) with 11 and 9 animals each, respectively; Ovariectomized control groups treated with 60 and 90 days (OVX 60 and OVX 90) with 10 and 9 animals each, respectively, ovariectomized and treated via gastric gavage with saline 0.9% [0.1ml / 100g Body Weight (BW)]; Ovariectomized groups + Resveratrol treated for 60 and 90 days (OVX + RES 60 and OVX + RES 90) with 11 and 9 animals each, respectively, ovariectomized and treated via gastric gavage with a solution of resveratrol in 95% ethanol diluted in distilled water (10 mg / kg BW). Biometric, physical, and biomechanical parameters of bones from the animals with greater quantities cortical (femur) and cancellous (vertebrae) contingent were analyzed, as well as the areal bone density of the vertebrae via DEXA, and the body weight of the animals. The biomechanical properties of the femurs were obtained by the three point bending test, and the lumbar vertebrae’s by the bone compression test. The experimental protocol of 60 days was able to remark the increase of the corporal weight of the rats after the castration, as well as the decrease of the vertebrae bone and mineral densities with the surgery and the protective effect of the resveratrol on these parameters of these same bones. In the 90-day protocol, these effects on the physical parameters were also extended to the femurs and the treatment, in this case, also able to prevent the greater corporal weight due to the castration as well. In the biomechanical parameters, it was possible to observe only a tendency of reduction of the maximum load with the surgery and protection with the treatment in the vertebrae of the longer experimental protocol. Therefore, the results indicate resveratrol, in the dose and route of administration used, as a potential protector of the bone tissue, both with greater cortical contingent and with greater cancellous contingent. In addition, the experimental protocol of 90 days showed be able to present more clearly the effects of castration and treatment with resveratrol on bone and body weight parameters.

    The structural behavior of the prestressed steel concrete composite beams was investigated using the Finite Element Method. The present study reports two types of composite beams: steel beams and concrete slab with joint work ensured for shear connectors, in a traditional way and partially encased composite beams. Initially, were presented and discussed the characteristics, advantages, disadvantages, applications and constructive aspects of this structural system, that can be used in the recovery and rehabilitation of existing structures or in new large structures design. Subsequently, were presented analytical expressions for the size of this structures. A numerical analysis methodology, that is, a modeling strategy using software ABAQUS® was developed and calibrated based on available bibliography experimental results for both types of composite beams presents in this paper. The composite beams of the conventional typology were modeled in two ways: interaction steel-concrete established with the perfect coupling of all the common nodes through TIE constraint; and interaction steel-concrete established with modeling of shear connectors and using contact interaction between surfaces. The partially encased composite beam was initially modeled and calibrated without application of the prestressing force, for later modeling of the tendons, due the misses of experimental results of the prestressed partially encased composite beams. The numerical methodology presents aspects related to the choice of finite elements used, mesh geometry, constitutive relations of materials, interaction between materials and loading procedures. Finally, a parametric study was developed for the composite beams with conventional typology. The objective of this study was analyzing the influence of the variation of the tendon eccentricity; of the variation of the tendon force and the influence of the layout of the prestressing tendons. In general, the modeling strategy for conventional composite beam was adequate to simulate its structural behavior, especially for the case where the interaction steel-concrete was established by the shear connectors. In the case of partially encased composite beams, was possible to see the effects of the prestressing on its structural behavior, due to the increase in the ultimate moments carrying capacity; smaller displacements and smaller deformations. In additions, there were good correlations of the ultimate moment carrying capacity obtained analytically and numerically.

    The relationships between economic growth, public spending and poverty are the targets of several studies, and their results highlight that GDP improvement is seen as the best way to reduce poverty. Based on this principle, this study aims to analyze whether there was pro-poor growth in the Brazilian states and the impact of public expenditures on income transfers and education on poverty reduction during the period from 2004 to 2014. Focus of the policies of income transfer and economic growth in the country. Considering the need to reach the proposed objective, a study of the subject was carried out to measure the relationship between economic growth and public spending with the reduction of poverty. In order to estimate the relationships between variables, the growth-poverty, poverty-inequality, and poverty-related elasticities of poverty in Brazil as a whole and in their states were calculated using a dynamic model by panel data. In view of the results obtained, it can be seen that in the country there is great divergence in the variation of poverty among the states. In addition, it is noted that the impact of spending on income transfers and education positively reflects the fall in poverty.

    The search for new compounds from natural products with high biological activity is an arduous task that has improved due to the evolution of instrumental analytical techniques. In addition, the use of medicinal herbs for the treatment of diseases is still used for generations and the pharmacological studies of these drugs evidences their biological activity. In spite of this, deforestation still grows in Brazil. The Bauhinia (pata-de-vaca), with more than 60 native species, are extensively used in Brazilian popular medicine for the control of diabetes. Thus, in 2009 B. forficata, B. variegata and/or B. affinis were included in the National List of Medicinal Plants of Interest to SUS (RENISUS). In this context, the present work reports the results of LC-HRMS and LC-SPE / NMR identification of compounds in leaves of Bauhinia longifolia, a species with few phytochemical studies, and the chemical differentiation of B. forficata, variegata, longifolia and affinis using LC-HRMS and unsupervised chemometric tools. Chromatographic conditions were developed using full factorial design and liquid chromatographic knowledge. With this method it was possible to characterize 74 (seventy-four) compounds in Bauhinia longifolia. Most of these were first identified in this species, namely phenolic acids, flavonoids O-glycosylated and proanthocyanidins. In addition, 6 (six) were isolated by LC-SPE and identified by NMR in which four (miricitrin, juglanin, afzelin, bauhiniastatin 2) are unknown for this species, especially bauhiniastatin 2 reported in the literature with anticancer properties. Futhermore, the chemical profile by LC-HRMS analyzed by hierarchical cluster analysis and principal component analysis differentiated the 4 species of Bauhinia and 24 other compounds were inferred. Thus, 99 (ninety-nine) compounds were identified in this thesis by providing important information that can be used in the quality control of ethanolic extracts of Bauhinia leaves, as well as to explain ethnotherapeutic properties, pharmacological and toxicological actions.

    People are increasingly wasting their time in indoors environments, in these locations there is a risk of contagion from diseases transmitted by the airways, due to low rates of air exchange. Thus, the number of causative agents of various diseases airborne spreads more rapidly, increasing cases of respiratory problems. Therefore, controlling the microorganisms present in indoor environments has become extremely necessary. An alternative is to develop filters for air conditioners, laminar flow hoods, and clean room exhausts that have antimicrobial properties. There are numerous materials that have an action against fungi and bacteria, among them silver and titanium dioxide. By combining these two materials a composite can be formed which is expected to have a synergistic effect. Thus, this thesis had as main objective the development of modified filter media with those nanomaterials that present antimicrobial capacity. After the modification of the filters, adhesion strength analyzes and peel velocity calculations between the nanomaterials and the fibers were done in order to ensure that they are not released into the environment. The results showed that the inhibition in the real environment was 55.6 ± 9.52, 72.2 ± 4.81 and 81.1 ± 1.92%, adhesion forces 3.44, 14.32 and 12, 24 nN and the average velocities required to release the nanomaterials of 125.2, 46.8 and 35.7 m / s for the silver, titanium dioxide and Ag/TiO2 nanoparticles respectively. These data suggest a considerable decrease in the number of microorganisms when using filters modified with these nanomaterials and have shown that the particles are removed at different speeds. However, with the results obtained it was not possible to point to a filter that satisfies all the evaluated parameters. The Ag/TiO2 modified filter showed greater inhibition capacity of the microorganisms, however, this material can be removed at lower speeds when compared to the other materials. The silver filter has the lowest inhibition rates, but high velocities are required to remove the particles adhered to it. Thus, the most appropriate filter is one that satisfies the operating conditions of the equipment on which it will be used.

    Microalgae are promising photosynthetic organisms, thus important for the biofixation of the CO2. They have the potential for application in various industrial sectors, such as in the production of renewable energy and in the area of fine chemistry. Microalgae biomass carries valueable biomolecules such as lipids, carbohydrates and proteins that can have their production optimized, depending on culture conditions. Species selection and identification of conditions that stimulate their growth is important for the development of large-scale cultures. The objectives of this research were to investigate the physiology of a Chlorophyta microalgae in different scales, analyse its biochemical composition and apply its biomass. For the development of this research we selected Chlorella sorokiniana among three Chlorophyta species based on growth rate, biomass yield and protein production in laboratory controlled experiments. These results are presented in chapter 1. In chapter 2, we scaled C. sorokiniana cultures up to 100 and 1000 L keeping them outdoors for the production of biomass and physiology evaluation under the natural conditions of light and temperature. The results showed less proteins and lipids in the biomass of large scale systems in comparison to the laboratory cultures. Although the phtosynthetic capacity was similar in either scale, the highest rate of carbon fixation was obtained in 100 L cultures. In chapter 3 the applicability of the biomass produced in the 1000 L cultures was investigated in vegetable seeds pelleting, whose viability was evaluated by monitoring the pelletized seeds germination. These results showed ~ 90% emergence and equivalence with the controls, so confirming the applicability of microalgae biomass in the composition of seed pelleting materials. Finally, in the 4th chapter we investigated if light emiting diodes (LEDs) of different colors would led to improvements in C. sorokiniana growth, biomass and photosynthetic physiology. For this, the cells were exposed to blue, red and a blend of 50% each blue and red LEDs accomplishing 100% of PAR as in the controls (white LED). We observed that S. sorokiniana exposed to red LED had the lowest biomass productivity (0.0025 mol C [mg Chl a-1 h-1]), dry biomass and growth rates and it was the most sensible culture to photosynthetic light reactions. Cultures exposued to the blue, and the blend of blue/red LEDs showed photosynthetic behavior similar to the control, in addition to higher biomass yield. From the present research as a whole we can conclude that C. sorokiniana is a robust freshwater Chlorophyta that supports the adverse conditions of outdoor cultures and that its biomass can be used in seeds pelleting. In addition, we showed that blue LED can improve C. sorokiniana productivity and modify its biochemical composition.

    Within a context of a growing global market of low-calorie products, it is possible to highlight the production of sweeteners – products whose sweetening capacity is similar to sucrose – among which is xylitol, a sugar metabolized independently of insulin action – which makes it tolerable by diabetics – found naturally in fruits, vegetables, yeasts, lichens and algae. Due to the economic unfeasibility of the polyol’s conventional methods of obtaining – solid-liquid extraction and catalytic reduction of xylose – many studies have been set up to formulate alternative means to produce it. Considered very promising, the biotechnological production consists of xylan fermentation, obtained from the acid or enzymatic hydrolysis of lignocellulosic materials rich in xylan, such as hemicellulosic hydrolysate of sugarcane bagasse, by capable microorganisms and consequent release of xylitol, as well as other metabolites in fermentation broth. Obtaining the product of interest gets related to its separation from the broth that, due to its complexity, presents a high cost in relation to the rest of the process, which motivates, therefore, the study of several techniques that enable it. Some examples discussed in the literature are: use of zeolites, resins, crystallization, activated carbon adsorption, liquid-liquid extraction, precipitation and membrane application. Therefore, the present study aimed the simulation, using the free softwares COCO and Scilab, of the fermentative step and the synthesis of the separation process that offers possible means to obtain xylitol produced in a microbiological environment, as well as the analysis of the behavior of the system and the properties of the substances involved in the simulation environment. For this, an integration module was used between the two softwares that enabled the resolution of the system of ordinary differential equations that describes the kinetic model of xylitol production by xylose fermentation by Candida tropicalis. From the result obtained for the system in the Scilab routine, using the properties of the feed stream defined in the COCO environment, the production of xylitol, which was 1260.37 kg.h-1, as well as the secondary metabolites, ethanol e glycerol, 237.14 kg.h-1 and 284.56 kg.h-1, respectively, that compose the flow to be purified in the subsequent steps, could be estimated. The proposed separation process consisted of liquid-liquid extraction using ethyl acetate as solvent and presented a reasonable behavior in terms of xylitol recovery, with loss of less than 1%, as reported by similar researches. Subsequently, unitary operations were used for solvent recovery as well as for the concentration of xylitol stream, resulting in a current with 73% w/w xylitol, which is equivalent to 0.18 kg per kg of feed xylose, and would in practice make it possible to crystallize and obtain the product of interest with a high degree of purity.

    Looking for competitiveness in global market, companies have been investing efforts: developing new products; changing ways of produce in order to reduce costs; and getting better quality on delivery (quality, velocity and flexibility). That is a route necessary to aim competitiveness to some companies, but to others, it is a survivor path. In the middle of all that movement, the production, planning and control areas (PPCs) are always affected, it raises the complexity of the system that has to be planned, scheduled and controlled. The past few years, in order to minimize the effects on PPCs area, companies have been investing great quantities of resources (financial, areas and people) in decision support systems (DSSs). DSSs are systems capable to help the decision maker, getting data and simulating scenarios online. This kind of investment minimizes the operational work of data collection and let to the manager the responsibility to make decisions. However, like other kinds of implementations that involve people, DSSs implementations have a small percentage of success when some critical factors are not considerate during the software choice, planning of implementation and during the implementation control. With this motivation, this work has the main goal to list a series of critical success factors (CSFs) of this kind of implementation. To ensure the achievement of the goals a systematic review was conducted looking for a literature list of the most cited factors. Afterwards, those factors listed were validated by four cases of study. During the literature review, we listed 27 factors to be considerate on DSSs implementations. 20 of 27 factors were validated by empirical research and belong those factors there were found some that should be considerated as CSFs to implement the software and some that should be considerated also to achieve better performance results. We highlight among then: (i) top management involvement during the implementation and after supporting decisions based on SSD utilization; (ii) interdepartmental cooperation, using at good communication and sharing strategic goals

    The use of prestressed hollow core slabs has increased significantly and, consequently various productive methods have emerged. These methods do not employ machinery such as extruders or slip former machine. In this research, a production method for prestressed hollow core slab cast into fixed formwork with EPS void former has been detailed and compared with the production that employs machinery. Although there are many producers of hollow core slabs with EPS void former in the Brazilian market, there is still a lack of knowledge about this precast product. Therefore, this research presents a review and recommendations with possible theoretical analyses to be applied within the structural design of this type of precast element, which should also meet the design requirements of the Brazilian codes of practice for cast in situ and precast concrete structures, as well as existent recommendations for prestressed hollow core slabs within the international literature. In order to validate the analytical proposals for design, an experimental program has been carried out comprising standard tests for prestressed hollow core slabs in accordance with international codes of practice and technical literature. Within the experimental program, 15 slabs with heights of 150 mm and were tested under bending and shear forces for simply supported slabs with span of 5,70 meters, comprising 12 shear tests and 3 bending tests. For the shear tests, the length of the span between the applied point load and slab support was varied. Three of the shear tests were carried out for slabs employing transverse reinforcement, while the nine remaining slabs were tested without transverse reinforcement. Complementing the experimental program, three bending tests with concentrated load were also carried out. According to the observed experimental results, the failure mode of the slabs within the shear tests was governed by anchorage failure of the strands. For the bending tests, the experimental results were consistent with the usual bending theory for prestressed members. Finally, for some tested slabs, it has been identified the failure mode was governed by the position of the EPS forming a void within the slab transversal section, which affects the thickness of the top flange. Therefore, an additional study was carried out to evaluate the influence of the cast in place structural topping to increase the bending moment resistance of the prestressed hollow core slab cast into fixed formwork with EPS void former. It is concluded that the use of the cast in place structural topping minimizes possible decreases in the resistant capacity of the prestressed hollow core slab cast into fixed formwork with EPS void former, during the manufacturing process.

    Brazilian agribusiness is expanding yearly, and Brazil is already world's third largest corn producer country. Corn is Brazil’s second largest produced grain, losing only to soybean. Corn is used not only for human and animal feeding, but also in the industrial and energy segments. Increase in grains demand has brought seeds to play a key role in debates about productivity, related to industrial chemical treatment and plant breeding. As in all other industrial activities, seed production generates waste. Nonconforming grains are discarded along the process, from harvesting to processing. Finding an environmentally and economically viable destination to the discarded grains, as well as reducing risks from co-responsibility are important challenges faced by agribusiness. Chemically treated grains discarded from corn production can be sent to landfills, incineration, composting, co-processing in cement kilns and ethanol production. This paper analyses and compares the alternatives for chemically treated grains handling, focusing on sustainable development. Projects management methodologies were used to help guiding decisions towards finding the best destination for the grains. The alternatives were firstly compared on their environmental aspects, through the review of Life Cycle Assessment studies. By the end of this session, sending the grains do landfill and co-processing were considered inadequate due to its great negative potential impacts to the environment. Subsequently, the cost benefit for the seed manufacturer company was analyzed, considering the price of which alternative and the risk by co-responsibility. Composting and incineration were found not attractive to the seeds manufacturer. The best destination among the alternatives was sending the discarded grains to ethanol production. Finally, a preliminary cost analysis was carried out for the implementation of the corn ethanol production plant. The results pointed to a capital cost of R$ 409 million and yearly production cost of R$ 109 million. The payoff time calculated for the investment was 16 years. To increase economic attractiveness, the project must go through further analysis and data revision before being implemented.

    The objective of this project was the study of polypropylene and natural fibers high filled composite panels, with and without coupling agents, and the extraction and study of three species of natural fibers as potential reinforcements: macaúba (Acrocomia aculeata) , fibers of the leaves of gravatá (Bromelia balansae) and fibers of the leaves of curauá (Ananas erectifolius). Their characterizations indicated the fibers of the gravate sheets with the greatest potential for reinforcement of the panels studied, presenting a 40 GPa elastic modulus, a crystallinity index of 58% and a thermal degradation start temperature around 244°C. Strategies of processing were used to determine the concentration of the coupling agents (5% (w/w) of PPMA and SEBS-MA) and the pressure of the molding of the panels. However, with the use of PPMA, there was a 150% increase in flexural strength and the presence of SEBS-MA increased by 150% the impact strength of the composites with 80% fiber, the value obtained being 40 J/m. The presence of high fiber fractions in the composites decreased the thermal resistance of the composites, determined by thermogravimetric analysis, by 10°C. The results of DSC and DMTA showed that the high fiber contents of gravatá restricted the mobility of the PP chains, reducing the crystallinity of the PP and shifting the Tg to larger values. The composites absorbed about 4.5% moisture and the values are lower when compared to commercial panels such as MDF and HDF. The work demonstrated the potential of high filled composite with gravata fibers obtained through thermokinetic mixing and hot compression molding.

    According to a current definition in Brazil, occupational therapy is a field of knowledge and intervention in health, education and in the social sphere, which brings together technologies and resources oriented to the emancipation and autonomy of people who have difficulty to insertion and participation in social life due to various and different problems. If we start from the conception that the occupational therapist's role in society is to worry about problems for which his knowledge and formation can contribute to the construction of solutions, which also happens in the field of education, it is important to discuss the themes of inclusive education, special education, and public school. The research that integrates this thesis has turned to occupational therapy and its interface with education, with the purpose of bringing together and understanding the propositions that occupational therapists have been doing for and in the "School". The question was how occupational therapists understand and consider (or not) school as a social institution that has been historically ambiguous and contradictory to deal with social inequalities, also being a source of social exclusion. Besides that in how occupational therapists position them selves in relation to school processes and about what assumptions will propose interventions and direct their attention in this field of science and practice. To answer these questions, some texts were initially collected, got together and systematized in the format of articles, searched through the combination of the descriptors: "occupational therapy" AND "school" and related versions in portuguese. Until April 2016, foreign articles were collected on the online databases of Web of Science and Scopus, with 1.265 texts found, whose titles, abstracts and keywords were read and analyzed for the application of exclusion and inclusion criteria that allowed the selection of 155 texts for reading in full. The selection of the national articles has made use of two ways, namely the SciELO online library - Scientific Electronic Library Online and the main national journals of the area: Cadernos de Terapia Ocupacional da UFSCar and Revista de Terapia Ocupacional da USP, bringing together a total of 31 texts for reading in full. In a second moment of the research, with the intention of raising occupational therapists involved with research and academic production in relation to the proposed theme, we opted to consult the Portal of the Directory of Research Groups in Brazil –CNPq, about groups of research in occupational therapy. After reading the names of the 57 groups found (January 2017), descriptions of their impacts and the objectives of the research lines that presented the interface between occupational therapy and education and/or school, six groups were selected, totaling 10 occupational therapists leading researchers or vice leaders. The curriculum of these researchers were consulted in the Plataforma Lattes of CNPq in order to verify and bringing together their academic productions in relation to the theme on the screen, allowing to choose among those with the most academic production, six occupational therapists leaders of the registered groups, the who were invited to collaborate with the research, in the form of an interview. All of them agreed to participate, and six individual interviews were made to talk about, discuss, question and reflect about their personal and academic trajectories for occupational therapy, on how they construct dialogue with education and on their perspectives about the theme. The data collected by the material composed of national and foreign articles, as well as the interviews, were organized into five thematic axes in order to delimit the theoretical arguments used to support and problematize the proposals of the occupational therapy and the dialogue with the field of education in the schools, namely: 1) The proposals of the occupational therapy for the field of education in the school: the foreign productions; 2) Social inclusion, school inclusion, the children with disabilities and the dialogue with occupational therapy; 3) Resources and devices for the practice of the occupational therapy in the school; 4) Child education, the child development and its interface with occupational therapy; 5) Childhood, adolescence and youths in situation of social vulnerability, the public school and occupational therapy. The main results of this work demonstrate that the therapeutic occupational intervention considers the school as a relevant social equipment that allows the access of popular groups to social visibility, educational experiences, cultural and/or, still, make possible better living conditions. However, their perspective has been placed on the construction of care processes shaped by the practice of health care, with a clinical logic with individual mechanisms of care. Taking the history of education and schooling, as well as its reality in the twenty-first century in Brazil, there is a need for a displacement that gives new contours to this practice, which must recognize that the participatory and social dimension of life, focus of attention in occupational therapy, is not reducible to the individual and private sphere of everyday school issues and/or problems.In this context, we believe that the moment is for the transformation of ideas, which need to consider in a differentiated way the teaching and learning process and the role of the school in front of the human formation, being aware of the limits of the school and acting on the possibilities and demands that it and the people who are in it, and/or who they want/should be present to occupational therapists.

    The new drugs are new like unproven fish anesthetics, although they have behaviors of induction and anesthetic recovery, only the monitoring of the electrophysiological results and the verification of the cardiorespiratory and neuronal activity of power over the confirmation and the anesthetic potential of the agent tested. The study was carried out with tambaqui juveniles, Colossoma macropomum through the monitoring of behavioral and electrophysiological occurrences, where its efficacy under the effect of anesthetic agents, cardiac support, electrocardiogram, heartbeat (FBO) and intensity of opercular beats (IBO) and electromyography, in addition to its antioxidant capacity. Incredible catary (ENP) and the essential of propofol (PRP) and the oil in which were tested from tests that were tested six PRP and OEN for agreement with preliminaries for the definition of tracks-test, a was able to provoke the sedimentation capacity in approximately 3 min and recovery in approximately 5 min for these tests were used in animals (n = 10) and the test times for each stage of sedation and anesthesia recovery, where a concentration ideal of 175 μL L - 1 for EON and 4 μL L - 1 for PRP. For electromyographic evaluation, electrocardiographic data, intensity of operative beats (OBI) and rate (OBR), fish (5.6 ± 1.8g, 8.0 ± 0.3cm, total length) were attributed to the following groups: a) control (baseline b) fish exposed to ethanol (control vehicle), c) fish submitted to induction with 175 μL L-1 EON and subsequent recovery and d) fish submitted to induction with PRP at 4 μL L-1 and subsequent recovery. Eight fish (n = 8) per group were used. Both products induced complete immobilization of the body and suppressed the contraction power of the dorsal muscle (99.9%), determining a state similar to general anesthesia. During exposure to any of the anesthetics, cardiac function was affected transiently, with decreased heart rate (42 - 43%) and mild arrhythmia in fish in PRP recovery. In addition, ventilatory capacity was reduced with this drug (85.3% and 59.6% reduction in OBI and OBR, respectively), but without mortality. On the other hand, EON did not alter ECG tracings, permitting maintenance of normal ventilation intensity during exposure, although a slight increase in OBR during deep anesthesia occurred. This study confirms the anesthesia with propofol in fish and presents the essential oil of Nepeta cataria as a new and safe natural anesthetic for juveniles of Colossoma macropomum and potentially for other species of teleosts.

    This study had as main goal to verify the analysis of teachers’ practices, within a classroom interection approach at elementary school. Also, to investigate how the teachers’ self-image, commenting and binding meanings to dialogues and stimulating verbal and social interaction connected with knowledge production. It is a qualitative study, whereby the data were colected in portuguese classes in a elementaly school’ bilingual classrom, in a municipal school located in a city of São Paulo state. The data colect was conducted, first, in the portuguese classes thru shooting the classes in such, the recordings were used in the next stage of the research, when the data was confronted between the teachers and their own work activities, those moments also were recorded and transcribed to analysis, considering the formulation of simple self-confrontation. The data analised, under Vygotsky’ historical social approach, and, with postulates of Bakthin’s theory of enunciation, indicated which are the medication actions that contribute to constructe meanings, considering the relation between writing in portuguese, mediated by discursive interactions in Brazilian Signal Language, showing the methodological effectiveness to create a self-thinking in the teachers that is looking foward to improve their education practices within the classroom. The data analysis indicated that the discussion about educational practices in bilingual classroms is importante, considering the quality of teaching portuguese writing as a second language; furthermore, allow to see aspects of the teacher-learning relationship that will enable possible ways to provide teacher formation for this audience.

    Exactly one month from completing five years since the Pinheirinho’s eviction, 1.461 of the 1.750 evicted families received the keys to their houses on Pinheirinho dos Palmares II, neighborhood built exclusively to them through the housing program Minha Casa Minha Vida (PMCMV) in São José dos Campos, inner city of the state of São Paulo. This dissertation describes and analyzes ethnographically the political fight’s process of the evicted families and the social movement which represented them, seeking the access to the house financing by Caixa Econômica Federal, operative agent of the housing program. Based on a fieldwork conducted through interviews and attendances to the events convened by the Movimento Urbano dos Sem-Teto (MUST), in the period between the eviction and the house’s key obtainment, I describe and analyze the uses and senses of the notions of political fight, house, memory and State by the evicted families from Pinheirinho and leaderships of the social movement in order to guarantee the access to own a house in Pinheirinho dos Palmares.

    Biological invasions are an important cause of biodiversity loss and occur when an exotic species is introduced out of its native range, possibly changing the structure and functioning of invaded communities. The invasion potential of aquatic macrophytes is often greater than showed by terrestrial plants, especially due to their generally high dispersal efficiency. Not coincidentally, aquatic invasive plants have been a major threat to multiple ecosystems worldwide. Hedychium coronarium is a perennial macrophyte native from tropical Asia, where it is common in the understory of moist ecosystems. It has been introduced elsewhere for ornamental uses, where is has showed high invasion potential. In this study we assessed experimentally how the productivity of H. coronarium (aboveground biomass and number of ramets by rhizome; ramet biomass and height) is affected by previous rhizome exposition to contrasting water, temperature and light regimes. We found that increasing flooding was associated to greater ramet and biomass production. In contrast, prolonged rhizome desiccation leaded to high rhizome and ramet mortality. Ramet biomass was slightly lower after rhizome exposition to a 35ºC than to a 25ºC temperature, and productivity was lower under complete darkness than at a 12h daily photoperiod. These findings show that H. coronarium tolerates a broad range of abiotic conditions and may adjust its clonal growth pattern to the local environment. This ability to maintain high invasion potential even under extreme abiotic conditions possibly plays an important role in the dominance of the species in riparian ecosystems and highlights the importance of developing effective management strategies to avoid further spread of the species.

    Predicates of personal taste (PPTs) are, as suggested by their name, predicates that speak of the personal taste of the speakers who utter them. They are diferent from the other predicates because they generate between the spekers disagreements in which, although one directly denies what the other says, no one is uttering something false – a phenomenom that has been called faultless disagreement in the literature (Lasersohn, 2005). In this work, we investigate some of the syntactic, semantic, and pragmatic aspects of predicates of personal taste, approaching the main problems that these items generate (the faultless disagreement being one of them, but not the only one), and how the literature about the theme deals with these problems and proposes a treatment for PPTs. We focus on three approaches: the relativist (Lasersohn, 2005; Stephenson, 2007), the contextualist (Pearson, 2013), and the expressivist (Gutzmann, 2016). Furthermore, we show how dta from Brazilian Portuguese contributes to the study of these constructions, casting a light on problems that are not approached in the English-directed theories, like, for example, the classification of these predicates in individual or stage level, and also how syntactic aspects of the language contribute to the generation of different inferences related to PPTs. Finally, we also show other items that behave in a similar manner to taste predicates and that could also be treated by a theory that is capable of explaning PPTs and their problems.

    Protected areas are considered one of the most important elements for biodiversity conservation. One of the pillars that sustain the management of these areas is scientific research, which provides the knowledge necessary for the conservation of environmental and historical-cultural heritage. The general objective of the present study was to evaluate the current state and propose improvements in the management of research of the State Parks of São Paulo in light of already existing practices of Knowledge Management. By the analysis of Research Programs present in the Management Plans of the Units, we identify the main aspects that underpin the research management and evaluate their effectiveness within the current context of each Park and for all the system (set of Parks). The main challenges pointed out in the evaluation were related to the lack of assurance regarding the return of the results of the surveys for management of the areas; the insufficiency of human resources directed to the execution of the activities foreseen in the Research Programs and the monitoring process carried out without periodicity and systematization. We could also observe the low correlation between well-managed Management Plans and Research Programs and the satisfactory performance of the actions foreseen in these documents, suggesting that the process of research management in these areas is not necessarily being directed by some planning instrument.

    The use of toxic bait represents an important tool when dealing with important agriculture and silviculture plagues, where hesperidin flavonoid complexation with magnesium(II) generates a compound (Mg(hesp)) with high effect against cutting ants. The aim of this study was to evaluate the effects of different concentrations of Mg(hesp) (0, 0.1, 1, 10, 100 e 1000 ng mL-1) using cytogenetic and biochemical biomarkers in vitro (zebrafish hepatocytes – ZF-L) and in vivo (Neotropical fish Prochilodus lineatus). Mg(hesp) has great impact in cell population (confluence and morphology) and in activity of cellular organelles (mitochondria and lysosome), in addition to affect cellular stability through generations of reactive oxygens species mainly in higher concentrations (100 e 1000 ng mL-1). Biochemical responses include GSH and MT role as antioxidant and biotransformation molecules. Genetic influence of Mg(hesp) could also be detected in nuclear abnormalities and DNA instability, leading to alterations in cell cycle of zebrafish hepatocytes but with a probable activation of repair mechanisms. Membrane damage and apoptosis and necrosis pathways were not observed. Cellular effects of Mg(hesp) in ZF-L represent consequences of effects in several cellular compartments, which probably lead to alternative death cell pathways. In vivo analyses also showed Mg(hesp) influences, including hematological alterations, impacting on oxygen availability. Events of DNA instability (increasing in DNA fragments and nuclear abnormalities) in erythrocytes and hepatocytes also were observed. However, the absence of micronuclei formation is a strong indicative of an effective action of repair mechanisms. Biochemical responses in P. lineatus did not presented a clear pattern, but were effective in prevent membrane damages. Thus, results indicate that Mg(hesp) influences occurred mainly after 24 h of exposure, while fewer damages were observed after 96 h, suggesting a potential capacity of organism recovery, emphasizing the importance of more assessments of Mg(hesp) effect and the promising use of this compound.
