We did this experiment in the Corumbataí river Basin, São Paulo, southeastern Brazil (22°41'28" S e 47°56'15'' O). In this Basin, the original phytophysiognomies were dramatically reduced; nowadays the native ecosystems are represented by small and fragmented seasonal semideciduous forest communities. Although these forests are very degraded, they represent the last forest remnants of this region. So, the conservation of their alfa and beta diversity should begin through description of their woody species composition. In this sense, the objective of this experiment was to describe the composition of trees and shrubs in the edges of seasonal semideciduous forests that are inserted in matrices of sugar cane and in consolidated pastures. We aimed to verify if different sources of disturbances may promote distinctive successional pathways, related to particular composition and structure between the forests inserted in sugar cane matrices, and those inside the consolidated pasture ones. We sampled 12 forest fragments in a systematical way , through sixty 8 m x 30 m plots (total sampled area: 1.44 ha) - 30 plots in sugar cane matrices, and 30 plots in pastures matrices (five plots per forest). We sampled the plants with the perimeter at breast height (PBH) equal or higher than 15 cm. We compared the floristic composition and structure between forest remnants by similarity dendrograms and ANOVA. We sampled 1,990 plants, belonging to 163 species (46 families). The forest communities presented low floristic similarity; we observed no significant differences in the structural patterns among the 12 forest fragments. These results indicate that both composition and structure of those communities were not related to the nature of the agricultural matrices. We also observed that the 12 communities have high values of diversity, despite they are inserted in a very modified landscape; such a result refers to their conservation. In this sense, we think that actions related to ecological management in landscape scale, and ecological restoration practices to improve the ecosystemic atributes of the seasonal semideciduous forests from Corumbataí river Basin are necessary.

Early identification of risk factors for changes in development enables the implementation process of early intervention and prevention of aggravations. Among these risk factors are prematurity. Prematurity is considered the main cause of death, morbidity and disability for children, triggering a series of risk factors for development, leading to the emergence of several clinical problems, being an important risk factor for the vision development. Among the problems presented by the premature newborn is Retinopathy of Prematurity (ROP), a vasoproliferative disease and leading cause of infant blindness. This research aimed to identify studies on ROP consolidated in theses and dissertations and scientific articles produced in Brazil in view of construct bibliometric indicators enabling to describe and analyze the scientific production from the perspective of Special Education. To develop the study, was used the methodological approach of bibliometrics from searches for pre-defined keywords. Theses and dissertations from thesis Bank of CAPES and scientific papers present in SciELO database were investigated, focused in Retinopathy of Prematurity. A total of 41 theses and dissertations and 33 articles were located, being the studies classified according to the nature, in principal and secondary. The results reveal that most of the studies on theses and dissertations related to subject of ROP are concentrated in Southeast region of Brazil. The interest in ROP research increased over the years, however these studies focus still in biomedical area, with newborns. A lack of studies in education area was identified, especially in Special Education. Is suggested the development of future studies in this field with children of different ages, in order to identify the impact of ROP on literacy / education of these children.

Mg-based nanocomposites are considered promising materials for hydrogen storage in the solid state. In this work, Mg-based nanocomposites containing iron-based (Fe, Fe2O3, FeF3) and niobium-based (Nb, Nb2O5, NbF5) additives were processed by different processing routes involving high energy ball milling and severe plastic deformation techniques. The high energy ball milling techniques are represented here by the reactive milling under hydrogen atmosphere and by the cryogenic milling while the severe plastic deformation technique is represented here by extensive cold rolling. An alternative processing route including a previous short ball milling step before the cold rolling processing was evaluated. The study of the effect of additives according to the chosen processing routes and an extensive characterization of the hydrogen storage properties allowed a better understanding on the mechanisms which are responsible by the kinetics improvements related to the microstructural particularities. The materials prepared by the different processing techniques were characterized by micro and nanostructural analysis techniques such as, among others, x-ray diffraction followed by the Rietveld method, scanning and transmission electron microscopy. The desorption behavior was studied by differential scanning calorimetry and the kinetic behavior was investigated by absorption and desorption cycles. The correlation of the results obtained with the different processing routes showed that the beneficial effect of the additives in promoting the H-sorption kinetics is positively extended independently of the processing route; however, the acting mechanisms depend on strictly on the preparation methods and the combination of one or more factor related to the microstructure. Furthermore, the severe plastic deformation techniques showed a very good potential in comparison with the high energy ball milling techniques in processing Mg-based nanocomposites, resulting in materials with good hydrogen storage properties.

This paper aims to discuss the mathematical Olympiads in terms of Bourdieu's theory, seeking demonstrate valorization strategies and adoption of the field of mathematics linked to social practices related to OBMEP. The concepts of field and symbolic capital were used for analysis of research papers in order to understand the mathematical Olympiads as a strategy for appreciate mathematical fields as well as a kind of normative evaluation. This paper promotes a discussion about the alleged role of social inclusion attributed to these competitions. The research is a qualitative approach and involved the preparation of a history of the Mathematical Olympiads, literature research and document analysis. Bourdieu's theory may us understand that the field of mathematics has sufficient capital to reward and recruit talent while it naturalizes, through this process, the ideology of the gift and the inculcation of a cultural arbitrary on the technological and scientific development, which is linked to factors and interests of the economic field. This critical view for the Olympiads can contribute to the expansion of studies in the field of mathematics education in relation to school evaluation and the symbolic value of mathematics, looking this as a kind of symbolic mechanism of domination, valorization and conservation of the field of mathematics. Then OBMEP can be understood as the manifestation of an alliance between the scientifical and political field, which simultaneously establishes the mathematical culture and corroborates the economic interests.

Diverse factors can compromise the growth and development of individuals including preterm birth. The literature from the area has indicated that children born prematurely may present altered growth and development, mental retardation and learning disabilities. Thus, preterm birth has been studied in diverse scientific fields including Special Education. In this field the studies focus on primary, secondary and tertiary attention, thus contributing to the prevention of deficiencies, to education strategies and to intervention procedures. The present research aims to verify what composes the field of preterm-birth studies in Brazil, from the Capes Thesis Registry, and also to assess the scientific collaboration networks at the intersection between Special Education and preterm births. The study is structured into two steps denominated Study 1 and Study 2. Study 1 corresponds to bibliometric analysis of scientific production on premature birth available in the Capes Theses Database with the objective of reporting the State of the Art in producing knowledge on this theme as reflected in Brazilian theses and dissertations. The methodology of Study 1 was developed in five steps: step 1: construction of a theoretical reference by reading the scientific texts from the areas of Special Education, Information Science and Preterm Birth to provide a scientific basis for the research; step 2: data collection sourced from abstracts of theses and dissertations available in the Capes Theses Database that presented the preterm topic, between 1987 and 2009; step 3: organization, treatment and construction of bibliometric indicators from the registries; step 4: analysis and interpretation of the results found, capturing the concepts exposed in the theoretical reference on scientific production on preterm birth to underpin the analyses of the data obtained. Study 2 corresponds to preterm-birth scientific collaboration networks in the Special Education field. The method of Study 2 involved identification of registries belonging to the Graduate Programs or research lines in Special Education. It was possible to identify 10 registries pertaining to the Graduate Program in Special Education of the Federal University of Sao Carlos and two linked to the Graduate Programs in Education, with research line directed toward Special Education, representing, respectively, the State University of Rio de Janeiro (UERJ) and Federal University of Santa Maria (UFSM). From these twelve registries were selected the curricula of the professors directing the theses and dissertations to compose the scientific collaboration network. The results of Study 1 reveal: increase in scientific production involving the topic during the study period (1987 to 2009); the production is mostly represented by Masters theses; the most highlighted institution was the University of Sao Paulo, rendering the southeast the most prominent region of the country. In relation to the large areas of knowledge, scientific production on preterm birth is concentrated in the Health Sciences area linked to programs in Medicine and Nursing. CAPES, CNPq and FAPESP were the primary funding agencies. As to the gender of thesis and dissertation authors, 79.8% are female and 20.2% male. It was also found that the predominant risk conception is medical/biological while the predominant study locations were neonatal intensive treatment units. The most frequent objectives were studies on aspects of breastfeeding, nutrition, suckling, weaning, periodontal diseases and milk composition. The majority of these studies were directed at preterm cases of gestational time from 31 to 34 weeks and with very low weight (>1500g). The results of Study 2 revealed that production via partnership, identified in the analyzed interface, is a trend in the academic environment; there are few relationships among the advisors or among the institutions that participated in the present study; as a counterpart, within the groups formed, we observed not only scientific collaboration between the different institutions but also a strong relationship between the advisor and advisee. The results presented herein contributed to a portrayal of the field of preterm-birth studies in Brazil which enables visualization of the potentialities and gaps in this knowledge area, to motivate researchers to seek new data sources, and when relevant and desirable, collaborative partnerships between research group and institutions.

The public position filled by appointment directly affects the governability and governance in the Brazilian political system, either for maintenance of a stable parliamentary basis or for the formulation and implementation of effective public policies. In the current democratic scenario, the appointment of policy makers with political responsibility and technical capability becomes a key element to the success of the government and enlarges its chance of electoral success. This work argues that the appointment criteria which were used by political parties have clear influence in the increase or decrease of the respective success electoral rates; from this perspective, the electoral result of the parties in the state of São Paulo in the post-redemocratization is here shown. Lastly, in a local case study, the appointment criteria which were used by mayors from parties whose programming and ideological fields are distinct will be shown.

The Dekasegi Phenomenon reveals a migratory flow that has caused suffering in the Japanese Brazilian community by fragmenting several families, with second and third generation descendants migrating to Japan, leaving behind parents, children and/or wives in Brazil. In this context we face several changes of previous roles and functions of each family member at home, forcing these people to overcome the distance and change their routines at home, rising questions to ponder in Social Anthropology, especially in its Kinship Theories. Characterized in contemporary Anthropological Theory as transnational families precisely for being constituted of members living apart in more than one country, dekasegi families live with a paradox and are still little studied in Anthropology: a series of economic, cultural, political, and other reasons makes it necessary for family members to be separated and sent to another country in order to keep the family united. This research proposes a study of dekasegi families living in Hamamatsu city, Shizuoka, known for being home to one of the largest contingents of Brazilians living in Japan. The main objective of this thesis is to shed light on how these Japanese Brazilians build their relationships not only with one another but also with family members left behind in Brazil aiming a better understanding of the internal dynamics of this migratory flow that has lasted for more than 20 years.

Cette Dissertation vise à explorer les conditions présentés par l'oeuvre de Michel Foucault pour constituer un concept de littérature comme alternative à l'option offerté par la phénoménologie et par l'existentialisme. Les écrits pionniers de l´auteur, ceux qui sont considérés comme antérieurs à la première formulation de l'archéologie du savoir, s´affilient aux présupposés de la phénoménologie, dont l'objet de recherche aurait été étendue par une psychologie existentielle que Foucault s´avait dédié à étudier sur un point de vue historique. Limitée à ce contexte, une notion précise de littérature se profilait dans l'horizon théorique de l'auteur. Cependant, avec le tournant archéologique qui aurait été reformuler ces présupposés phénoménologique jusqu'alors admis, Foucault passerait à concevoir la littérature autrement. C'est à ce concept spécifique de la littérature, désormais crié par l'auteur, que cette étude se propose à explorer. À cette fin, on se soutient sur deux autres notions qui mantiennent avec la littérature une relation très intime: la notion d'espace et la notion de dehors. Si la littérature cherche à composer une espace propre, autonome par rapport à tous les autres espaces, elle est aussi à la limite de tous les autres, en les attirant au dehors d´eux-mêmes, en se mêlant avec eux et en les subvertant. Il est concevable qu'une telle tension établi dans l´espace littéraire qui reste au dehors de tous les autres espaces et, au même temps, aux limites de ses virtualités, le remet à une condition paradigmatique, qui pourrait trouver des correlats en d´autres moments de la production foucauldienne.

Time series forecasting is probably one of the most primordial interests on economics and econometrics, and the literature on this subject is extremely vast. Due to technological growth in recent decades, large amounts of time series are daily collected; which, in a first moment, it requires forecasts according a fixed horizon; and on the second moment the forecasts must be constantly updated, making it impractical to human interaction. Towards this direction, computational procedures that are able to model and return accurate forecasts are required in several research areas. The search for models with high predictive power is an issue that has resulted in a large number of publications in the area of forecasting models. We propose to do a theorical and applied study of forecasting methods applied to multiple univariate time series. The study was based on exponential smoothing via state space approach, automatic ARIMA methods and the generalized Theta method. Each model and method were applied in large data bases of univariate time series and the forecast errors were evaluated. We also propose an approach to estimate the Theta coefficients, as well as a redefinition of the method regarding the number of decomposition lines, extrapolation methods and a combining approach.

This narrative describes the attitudinal, psychomotor and cognitive, personal and professional, mobilized by the experience with the Educational Unit of Professional Practice of the UFSCar Medicine Course. It was not an easy path and pedagogically below expectations. However, the balance was positive in terms of personal growth, development of skills such as adaptation and resilience, as well as for the development of a special doctor-patient relationship.

This study is the result of doctoral research entitled How Teachers see the school inclusion of students with disabilities in regular schools . It was held in public schools in a city in the central region of São Paulo state. The survey was conducted from 2009 to 2012 in five public schools of basic education. Our entry into this study was accompanied by two questions: from one side analyzes how teachers see the inclusion of students with disabilities who are enrolled in regular school, from the other side get to know how teachers understand about the occurrence of the inclusion in regular school. The theoretical reference on which we based to carry through this study was about issues such as: conception and background of the teachers, curriculum adaptations besides references that would enable is to analyze the discourses of the teachers who are working in elementary and high schools in São Paulo state. Our research question in this study was: how teachers see the school inclusion of students with disabilities enrolled in regular schools in different educational levels? The objectives of the study were: a) Identify how teachers see the school inclusion of students with disabilities included in the regular teaching in state schools for basic education; b) Analyze how they see the process for inclusion of these students; c) understand how the process has been occurring for inclusion in the perspective of teachers who teach classes to students with disabilities in different educational levels; d) Investigate whether the pedagogical practice of teachers working in basic education schools has contributed to the schools inclusion of students with disabilities in regular education. The methodological option was qualitative research whose investigative method was discourse analysis since our target of analysis were the discourse of teachers who are working in the public schools and teach students with disabilities. The results led is to reflect the need to invest in teacher training not only in the initial level, but also in continued education, because it was evident to is vehement necessity of training the teachers to teach students who are attending schools in various levels. Our considerations concerning this study are that if we do not invest in training teachers for initial and continued education, we will definitely find difficulties to promote the inclusion of all people, it doesn t matter whether they are disabled or not in the school premises.

This study aimed to analyze the contribution of molecular models to the evolution process of the mental models of first grade high school students regarding the following chemical concepts: substance, reactants, products, rearrangement, Proust s Law, Lavoisier s Law, balancing, stoichiometry and submicroscopic representation of chemical reactions. The project involved the participation of 335 students and 06 teachers from three public schools in the region of São Carlos/SP. Data collection was performed in two stages: the first one took place at the schools during the 2011, school year, and the other occurred during a short course offered for the students, in the vacation period, at the Laboratory for Chemistry Teaching and Learning (LENAQ) of the University Federal of São Carlos/SP. Activities that addressed the concepts mentioned were elaborated and each student had an Atomlig® molecular model kit and a plastic balance that could be used to help solving the questions. Data were collected through written records, interviews and filming. It was found that most students (47.2%) showed a significant evolution of the mental models for the selected chemical concepts. A considerable portion (45.1%) showed an oscillation with respect to understanding of the concepts, while some students (7.4%) kept a constant performance and a minority (0.3%) showed a regression throughout the school year. The data allowed us to infer that, in general, students showed evidence of significant learning during the short course, highlighting the relevance of molecular models to the evolution process of student s mental models.

In the last two decades a remarkable progress in nanomaterials knowledge has been done, mainly in the chemical synthesis of inorganic nanocrystals via colloidal processes. Several of these advances addressed the growth control of their organization structures and morphologies. Considering this perspective, this thesis presents the results of the crystal growth of gadolinium cerium oxide (CGO), as discussed in the first chapter of the results. In this system, the colloidal state effect on the growth mechanism by oriented attachment (OA) was evaluated. In the process of OA basically two approaches can be considered for growth. An associated effect of the collision of the particles mutually oriented that takes place in the dispersed colloidal state and other through attachment induced by rotation and alignment that was used for the growth of CGO, controlling the pH of the system. In this process CGO nanorods were attained during the hydrothermal processing of the colloidal suspension. In the second chapter of results, the crystal growth using an organic solvent was analyzed, in which a weakly flocculated colloidal state was achieved and led to the growth of TiO2 nanorods. The stability of nanorods was evaluated at different times of solvothermal treatment allowing the evaluation of the thermodynamic evolution of the structure. In this process, nanorods structures were divided into smaller structures by a detachment mechanism. By using the high resolution transmission electron microscopy technique the different stages of the process were evaluated, initially identifying formation mechanism by OA to growth the nanorods. Afterwards, a surface diffusion drives to a thermodynamically stable structure, followed by a detachment mechanism that leads to bipyramidal structures. Considering the two systems evaluated, it was concluded that by mastering the interparticle interactions it was possible to growth anisotropic structures, but their stability is constrained by the principles of thermodynamics. In order to control the self-assembly of nanocrystals, the third chapter of results presents the superlattices structures built with zirconium oxide colloidal nanocrystals. In this system, by using nanoparticles with a narrow size distribution and by controlling the interaction between the solvent and the organic molecule bound to the nanocrystals surface, self-assembled superlattices were attained. By controlling these interactions, compact structures were obtained resulting in single and multilayer. The results pointed out that the ability to organize nanocrystals into hierarchical structures, depends crucially on the ability to understand and control of the interparticle interactions.

This research fits in the technological development area and is aimed to evaluate the effects of adding waste of rigid polyurethane foam in the polymeric compounds based on polypropylene. The results of this research will certainly contribute to finding a solution to the large volume of industrial wastes of rigid polyurethane foam that arise from the waste process of handling thermal insulation from the production of refrigerators and freezers. The analysis of the effects of adding scraps of rigid foam in polypropylene copolymer was made by evaluating the physical, mechanical and thermal properties of the compounds when compared to the behavior of neat polypropylene. Moreover, the technique of Scanning Electron Microscopy was used to observe the microstructure of the final compound. The rigid polyurethane foam, after grinding, was incorporated into polypropylene by blending on the twin extruder and then the granulated materials obtained were injected to obtain the samples. In general, the compounds showed good processability in the experimental phase and looked good as can be seen in the SEM micrographs. The mechanical properties showed that the incorporation of PUR in PP copolymers promoted a brittle behavior in the compounds decreasing the main mechanical properties tested. However, the addition of the compatibilizing agent used, PP-g-MA helped in improving these properties. The use of PUR in polypropylene compounds brought advantages in terms of reducing waste disposal and thus has economic and environmental advantages and also viability in applications where high mechanical strength is not required.

One of the biggest challenges faced by companies is the production flow coordination along the supply chain (SC) in which they operate. Thus, practices have been developed both in academic and business environments that are used in supply chain management (SCM) since the late 1980's that allows such coordination. For manufacturing flow management process within the plant of a single company, the knowledge about usage of ordering systems can be found in current literature. Thus, the purpose of this thesis is to propose the use of the combined practices in SCM and pull ordering systems in SC. However, these ordering systems are seldom used for coordinating operations in SC, thus, can be assumed with a theoretical gap being exploited in terms of coordination mechanism of production flow in CS. The theoretical and empirical approach was used as methodological procedures. In terms of theory a bibliographic review was applied and was built a conceptual model. In terms empirical, was applied the conceptual model in a real case and was analyzed their consistence and result by simulation. A literature review was conducted to ensure the meaning of production flow coordination and SC and a detailed view of activities that theoretically ensures such coordination through the implementation of the Manufacturing Flow Management Process (MFMP). Based on this set of activities, a survey of the practices used in SCM and a conceptual analysis of contribution of with practice to the MFMP was performed. Meanwhile, another theoretical survey about pull ordering systems was performed with report analysis on the literature about the use of SC. Based on the elements that condone the use of each used practice in SCM and each pull ordering systems, a conceptual model of decision making for the combined use of both was designed. This model can help managers on decision making regarding the best practices and systems for each situation of pull systems. In order to validate the model a case study was performed in an automobile SC. The conceptual model was applied in two cases of the relationship with their suppliers and the impact on production flow coordination was analyzed through simulation. Based on the selected analysis variables there was an increase in the level of production flow management in all cases from the combined use of the practices compared to the previous case. To conclude it can be stated that through appropriate choices of combined use of practices used in SCM and pull ordering systems it is possible to achieve greater production flow coordination in SC.

Experimental studies of 3-methylpiridyne/water and 3- methylpiridyne/heavy water binary mixtures show solubility differences. In this work Molecular Dynamics method was used to simulate 54 model systems. Each system corresponds to a point at a temperature vs molar fractions phase diagram. The systems were simulated in cubic boxes containing a mixture of 3- metylpiridyne/water/heavy water in compositions ranging from 0.1 to 0.9 (molar fraction of 3-methylpiridyne) and temperatures ranging from 280 to 380 K. The results indicate that the interactions that contribute most for the 3-metilpiridine solubility in water and heavy water are the H/D bonds with the N at the 3- methylpiridyne. Those H/D bonds tend to be more structured as we increase the organic molecule concentration and decrease the system temperature. The local concentration analyses show that the first hydration shell of the nitrogen site has the same quantities of water and heavy water. Despite that there are more H bonds than D bonds at the first hydration shell. From this result we conclude that there are structural differences on the shell favoring the H bonds. The magnitude of those differences seems to vary with the temperature and the composition of the system. Our studies of H/D bonds lifetime show that there are not significant differences between the H and D bonds with the N site.

This research investigated what are the mathematical and methodological knowledge produced, recognized and redefined by teachers of childhood education, when they gather in a study group about mathematics education in childhood; and what are the signs of professional development manifested by the participants of the group in the process of continuing training. The objectives were: to analyse the formative processes of constitution and maintenance of the GEOOM group; to highlight the learning process that started from within the group; and identify the production, recognition and ressignification of the mathematical and methodological knowledge revealed in the oral and written narratives. This is a survey of qualitative nature that, through the analysis of content, followed the process of setting up and maintaining a group in which 39 childhood education teachers of the municipal network of São Carlos/SP met and lived - in moments and spaces of time not always coincident - for five semesters. The empirical materials were built from the reflexive narratives (oral and written) produced by the teachers, the reflective journal from the trainer-researcher and questionnaires (initial and final) answered by the teachers. From the data, the following aspects were identified: the conceptions of child education and mathematical education of teachers participant in the group; methodological approaches resized by the teachers in the process of formation in the group; the mathematical knowledge that are workable from games, children's stories and situations problems; the aspects of collaborative learning that occurred in the group; and the group blog as a means of socialization of the knowledge produced. The theoretical framework was sustained by the studies of Barbosa and Faria, Kishimoto and Grando, Van de Walle and Moura, Imbernón, Hargreaves, Ponte, Day, Fiorentini, among others. The mutual help between the involved and the relationship of trust established in the group wasn t enough for allowing, in a more spontaneous way, the negotiation of meanings and the exchange of mathematical ideas. The university-school partnership in decisionmaking was expected by the teachers as a way to validate their teaching practice.

The overall aim of this thesis was to investigate relevant variables to relational learning and the emergence of symbolic behavior in people with autism, in the teaching of reading. Were conducted three studies that are independent and yet complementary. Chapter 1 describes a study that evaluated the performance of forty participants with autism and forty with intellectual disabilities in identity matching-to-sample task, in the typical organization (one model and three comparisons) and in the organization with more than one model (three models and three comparisons), in two forms of presentation that needed different response modes: on tabletop and by computer. The general results of the participants indicated better performance in the organization with more than one model, in paper and in computer. Chapter 2 presents a study that aimed to teach basic reading skills to five participants with autism (four speakers and one nonspeaker), from the teaching of arbitrary relations among pictures and printed words, using adapted matching-to-sample task. Participants learned basic reading skills, but not showed combinatorial reading. Chapter 3 presents a study designed to teach combinatorial reading with comprehension for three participants with autism, from the teaching of naming syllables, words, pictures, and the formation of stimulus equivalence classes. Participants learned combinatorial reading with comprehension, with few training sessions and low numbers of errors during the teaching. The set of studies indicate the possibility of symbolic learning by people with autism since appropriate teaching procedures are used.

In this work were isolated eighteen secondary metabolites from Ruta graveolens (Rutaceae), eleven alkaloids (five akridonic, five quinolinics and one quinolonic) and seven furanocoumarins. Thirteen compounds had their herbicide potential evaluated in vitro and in vivo. The inhibitory activity of photosynthesis in vitro was determined by Hill reaction and the active compounds were classified as inhibitors of electron transport and the mechanisms of action were located in the photosystems (PSI and PSII). Studies of chlorophyll a fluorescence in leaf discs of S. oreaceae (semi in vivo) and in plants Lolium pereni (in vivo) confirm the electron transport results. The quantitative analysis parameters of fluorescence`s kinetics were measured and evaluated by energy flows absorbed by PSII antenna system, energy used for QA reduction, energy used for electron transport, and energy dissipation of flow as heat, fluorescence or transferred to other photosystems. In fluorescence in leaf disk, the Plabs parameter showed a decrease of 70% at concentration of 150μM, indicating a stress on the photosynthetic apparatus. Evaluating other parameters, were observed reductions in the PSI0, PHI(E0) and ET0/CS0 and ET0/RC of 40%, 40%, 60% and 40% at 150μM respectively, showing that at low concentrations the effect is intensified for the substance 2-nonyl-N-methyl-4- quinoline. Tests were performed by dry biomass, and the substance 4-methoxy- 7H-furo [3,2-g] chromene-7-one (bergapten) inhibited the growth of grass l. pereni in 20 and 23% at concentrations of 150 and 300μM, acting as postemergent herbicide. The isolated and evaluated compounds can be used as bioherbicides directly or as prototypes of new herbicides for weed control.

General ly, the debates about climate change are treat ies between the high polit ical, economic and academic classes, without taking into account the most vulnerable social groups, such as indigenous groups. The possible impacts of these changes in biodiversity, as wel l as other points of analysis, are already not only mea surable, but also perceived by dif ferent populat ions. This study presents the percept ion about climate change among the Indians Baré in Tabocal dos Pereira, indigenous community located in São Gabriel da Cachoei ra city, in the black River , Amazonas State. The work took the quali tat ive methodology with ethnographic focus. Important percept ions regarding climate change were highl ighted, concluding that today the theme cl imate is presented in the Baré culture.
