The aim of this research, based on the French Discourse Analysis theoretical and methodological approach, is analyzing discursively how Folha de S. Paulo (a Brazilian newspaper of significant circulation) narratively published the Portuguese Language Orthographic Agreement of 1990, which came into force in January 1st, 2009. As temporal outline, we established the period from January 1st, 2008 (a year before the effective coming into force of the agreement among the Portuguese language countries) to January 1st, 2010 (a year after it comes into force). Our main purpose is understanding during this period how the verbal sequence acordo ortográfico (spelling agreement), when it slides to reforma ortográfica (spelling reform), can be understood as a formula: an object which is describable in language categories and whose destiny at the same time invasive and continuously questioned inside the public discourses is determined by language practices and by the state of opinion and power relations in a specific moment in the very heart of the public space. (Krieg-Planque, 2009, p. 14). In other words, we have the objective of verifying on this paper during this established period how this syntagm reforma ortográfica, even though it is formally stable in the point of view of the linguistic description and explanation, is performed by the medium work in the public space discourses as a sequence both shared and problematic, knowing a discursive regime that makes it a formula.

The present study aimed to perform a music perception training for musically untrained individuals. Four university students were asked to identify major, minor and seventh chords. After hearing the sounds, they were reinforced for choosing the right image, which were either the chords guitar charts or the words MAIOR , MENOR and SÉTIMA (major, minor and seventh in Portuguese). After the training, the relation between words and charts was tested, and then, a generalization test took place in order to verify the identification of unheard chords. After this test, a new training was conducted with chords from a different root note. New equivalence tests were added, involving the different charts trained. Then, there a new generalization test was carried out, followed by the last training phase and the last testing phase. The participants generalized the trained discriminations to untrained stimuli, with an increasing score as they advanced through the procedure. However, some participants weren t able to achieve the criterion score in the more complex training sessions. These participants performed the equivalence tests, and their score was significantly lower than expected, failing to replicate prior results, and suggesting a link between difficulty in training and equivalence classes formation.

This research aims to salvage and registry a media still rarely studied in Brazil, because this was almost always seen as a smaller media, or just a branch of the commercial video, and the study of the director's role within this work. The role of music video director, unlike film director, is several times relegated to the background or ignored by the media and public, linking directly to the band's work, forgetting that there is an author. Still, several years ago, the video has acquired a higher status with the evolution of their language and able to unite the art trade, in order to make the band portrayed retains its personality and work of the director can show his signature in the work, and be received extremely positive, especially for youth. Leveraging the Manguebeat is a broad movement that proposes the development through dialogue with the traditions and diversity, based on Brazilian culture, we believe appropriate to talk of the music video with Brazil against the backdrop of this universe. For this, we intend to study the work of two directors: Raul Machado and Gringo Cardia, as well as the historical and ideological implications of the movement Manguebeat, and from this analysis, to confront the vision of each of the directors before the movement, through the look that they portrayed in their music videos Manguetown (Gringo Cardia - 1996) and Maracatu Atômico (Raul Machado - 1996), performing a thorough analysis of the works, and compare them to some impressive music videos of the time.

Resources sharing is one of the main characteristics of Automated Manufacturing Systems (SMA), this characteristic can be a synonym of advantages but on the other hand it may lead to the problem of deadlock. Several papers have suggested methods and techniques to reduce or eliminate the occurrence of deadlocks in SMA systems. The deadlock resolution strategies suggested in the literature can be classified into the following types: deadlock detection and recovery, deadlock prevention and deadlock avoidance. This work proposes a resolution method for the control of automated manufacturing systems using colored Petri nets, the main goal of the proposed method is to provide a deadlock-free production controller. To model, simulate and implement the technique in a production controller a dedicated software is used to model the Petri Nets. Initially, a model using Colored Petri Nets is proposed, then changes in the model are introduced in order to eliminate the deadlocks, resulting in a Colored Petri net control model of the SMA. Finally the model is implemented in the scenario of a Flexible Manufacturing System for testing and validation of the method.

ABSTRACT The management of the workforce takes different configurations. According with specific historical and social contexts, we observe the emergence of different orderings in which the relation between capital and labor is increased beyond the conditions stated objective. We analyzed one of these contexts in a traditional sugar mill and ethanol in the region of Ribeirao Preto, state of São Paulo, between the 1960 and 1990. Originated from a farm that was once the second largest producer of coffee, this plant has retained many features of that period as the provision of housing of old "colonies" and the management of patrimonial work, reconciled with elements of rationalization of production and work. The approach allows us to assert that conjuncture the existence of an effective link between the traditional and modern forms, which established relationships between plant owners and residents. So specifically, we found a set of counterparts given by the company families of residents, with regard not only to housing but also the entry and growth within the frameworks of these hierarchical the company. Through the company's historical reconstruction and recovery the trajectories of the families who resided in their homes, discuss this model, its intrinsic characteristics, as well as the conditions that led to his disappearance on account of restructuring production in the 1990.

The hatchery is now the main obstacle of aquaculture. The live food, especially zooplankton, is essential in early life stages of fish. However, there are difficulties in obtaining enough biomass. The Anostraca Dendrocephalus brasiliensis, known as branconeta, has great potential of use in national aquaculture. In this study, it was performed experiments of food selectivity and secondary production with fingerlings of matrinxã (Brycon cephalus) and pintado-da-amazônia, a hybrid between Pseudoplatystoma corruscans and Leiarius marmoratus, using D. brasiliensis and other species of zooplankton as food. Food selectivity results were evaluated using the Ivlev selectivity index and the coefficient of food Paloheimo. For both species, the indexes of the juveniles indicated a preference by D. brasiliensis in comparison to zooplankton. Secondary production values were better when matrinxã was fed with Artemia plus artificial food; there was no significant difference to fish fed with branconeta. For pintado-da-amazônia, the highest production was obtained from branconeta treatment. So, the selectivity for D. brasiliensis is positive, once it was accepted by both species, without rejection. The results allow us to assert that the use of D. brasiliensis is suitable for the cultivation of both species.

The buffer zones around protected areas are often suggested as complementary areas of conservation, but are rarely evaluated. In Brazil, the buffer zones are treated as secondary theme and when deployed, their perimeters are arbitrated. The lack of a script, but also specific regulations for the planning of buffer zones limit the ability to include this territory in the process of organizing conservation. This study aimed to review the legal and ecological principles that have guided the establishment of buffer zones; propose a roadmap based on ecological criteria for buffer zones to plan and implement the proposed method for establishing the buffer zone of National Park Pond Fish, Mostardas, RS. To define the perimeter of the zone, the script relies on the conservation objectives of protected area, the impacts that threaten these goals and structure of the surrounding landscape, identifying conservation opportunities. This information was treated quantitatively using a GIS and spatialized generating scenarios for discussion and the perimeter of the most appropriate choice. The method favors the participation of local communities in decision-making, encouraging the creation of spaces to be exercised co-management of the buffer zone and protected area itself. Using the model created a buffer zone for the National Park of Lagoa do Peixe, mustards, RS, even contemplating a range of marine protection. The buffer zone proposal adds an area around the unit with approximately 150,000 hectares, complementing and supplementing more than 33,000 hectares of habitat for conservation of interest. The model showed, among other things, that landscape structure plays an important role in defining the perimeter of the buffer zone. The adoption of the roadmap should fill an important gap in conservation planning, especially with regard to zoning of protected areas.

The influence of Al toxicity on the development of the root system and on the interference of nutrient absorption, typical of acidic soils, has been presented as one of the main causes of the low productivity of many crops of economic concern. The objectives of this study were: to evaluate the root development of maize plants, Dow 2B655, AG 8061 pro, Al Bandeirante, and DKB 747 varieties, in nutritive solution with different conditions of Al stress (0, 55, 111, 222, 444, and 666 µmol L-¹); examine morphological changes in the roots of maize seedlings through optical microscopy; verify the penetration of Al in the root tissue with the use of hematoxylin dye. The experiment was carried out under laboratory conditions, in a completely randomized design, with four replications. The results of root growth rate (cm day-1) were subjected to analysis of variance and compared by Tukey's test (p<0.05). Morphological parameters of Al in root tissues, indicated by staining, were explored in the form of images by photographic recording of observations under the optical microscope. The increase in the concentration of Al in solution caused a decrease in the rate of root elongation of all maize varieties. The critical concentration of Al in solution, which initiated the deterioration processes of the root apex, was 111 mol Al L-1. The main morphological changes in the roots, that is, the production of callose and the collapse and deformation of the hood, started from the critical concentration of 111 mol Al L-1 only in the AG 8061 variety. For the Al. Bandeirante, DKB 747, and Dow 2B655 mayze varieties, physiological injuries to the root apices were caused by concentrations of Al in solution greater than 444 mol Al L-1. The hematoxylin dye helped to indicate the accumulation and location of Al in the root tissue. The root biometry indicated that the Al. Bandeirante and Ag. 8061 mayze varieties were more tolerant to Al in solution, while the Dow 2B655 and DKB 747 varieties were the most sensitive. However, visual examination by the hematoxylin method and by optical microscopy indicated the following sequence of mayze varieties tolerance to Al in solution: Al Bandeirante > Dow 255 = DKB 747 > Ag 806.

CHEMICAL STUDY OF PATHOGENS AND VECTORS DISEASE OF CITRUS: Xylella fastidiosa & Diaphorina citri. Historically the national citriculture suffered great changes because of phytosanitary problems, and nowadays among the main threats to citruculture are the Huanglongbing (HLB) or Greening and the Citrus Variegated Chlorosis (CVC). The bacteria Xylella fastidiosa is the etiologic agent of Citrus Variegated Chlorosis. The HBL is associated to a bacterium that belongs to the Candidatus Liberibacter genera and its dissemination is by grafting of infected material or by psyllids. This work describes the chemical study of bacteria Xylella fastidiosa and the olfatometric response of Diaphorina citri to Citrus species. The X. fastidiosa (9a5c) were cultivated in PW medium. In the chemical study of X. fastidiosa the identification techniques used were CG-EM, LC-MS e LC-SPENMR. These techniques allowed the identification of fatty acid derivatives and diketopiperazinic alkaloids. This is the first chemical study of X. fastidiosa that boarded the alkaloids production cyclo (Pro-Val), cyclo (Val-Phe), cyclo (Tyr-Tyr), cyclo (Phe-Tyr), cyclo (Pro-Phe), cyclo (Leu-Leu), cyclo (Leu-Ile), cyclo (Val-Leu), cyclo (Ala-Leu), cyclo (Ala-Pro) cyclo (Pro-Leu), cyclo (Pro-Tyr), cyclo (Tyr-Pro), cyclo (Tyr-Val), cyclo (Pro-Ile), cyclo (Phe- Ile), cyclo (Arg-Val), cyclo (Leu-Phe), cyclo (Gly-Phe). Volatile compounds produced by X. fastidiosa extracted by SPME allowed the identification of methyl ketones and alcohols. The behavior study of D. citri to Citrus species essential oils, using olfatometric assays showed higher attractiveness to Citrus reticulata Blanco, Citrus paradisi Macfad., Citrus medica L. and the standard Murraya paniculata. However, lower attractiveness of D. citri was observed to hybrid species tangor Murcott, citrumelo Swingle e citrange Trover, that showed a high percentual of sesquiterpene compounds in the chemical composition. As complementary subsidy for understanding the interactions between D. citri-host the Principal Components Analysis (PCA) and Hierarchical Clusters Analysis (HCA) were carried out, these analyses demonstrated a group between tangor Murcott e citrumelo Swingle that indicate chemical similarity.

Nowadays, even small-sized enterprises are investing in integrated management systems, called ERP (Enterprise Resource Planning), as a way to solve planning problems and to better control their cash flow. However, these enterprises end up neglecting one of the main inputs to improve the PPC (Production Planning and Control): the demand forecast. Thus, planning and cash flow problems persist, and no matter how flexible the enterprise is, it cannot follow the demand due to limited resources. Another factor is related to the responsibility of elaborating the sales forecast, which a single area or department is in charge of and reflects all the development of the enterprise, in case values are not reliable. This work fits context, once its main goal is to present a process which combines various methods or forecasting techniques, integrating areas or departments as a whole, and sharing the responsibilities to obtain a consensual preview accepted by all. This process aims to align the revenue goals defined by the board and make possible actions with advance, in case it is seen that the objectives cannot be achieved in revenue terms, promoting coordinated actions between the commercial and productive areas, searching for a common outcome in financial terms. The proposed method also aims to improve the way of communication among areas, integrating the information and trying to suggest an evaluation and analysis process of the performed forecasts, apart from proposing an incentive to the commercial area to search for accuracy in the forecasts. The final outcome of demand forecast process will be a master production scheduling. A theoretical-empirical analysis is presented, and the research, based on literature, identifies, from the production system evolution, the production planning and control the demand forecast process, its forecasting techniques and the evaluation of errors. Next, demand forecasting processes is presented, as a way to improve the demand forecast identified in the case study and demonstrate the expected outcomes after the implementation of this demand forecast model.

Cerebral Palsy (CP) is a chronic condition that affects the motor development and posture of the child, often accompanied by disorders in speech, hearing, cognition, sensory perception, among others. This situation is responsible for changes and limitations in daily activities of children requiring adaptations by the family that plays a fundamental role in the rehabilitation process of children with CP, and partner and co-responsibility in child care. This study aims to evaluate the experience of families of children with CP treated at an outpatient child and investigate the impact of chronic disease in children in the family context. This is a qualitative study, which adopted the theoretical Symbolic Interactionism (SI). The study site was a specialized unit in the care of children in a midsize city in the interior of São Paulo state. To collect data we used an instrument composed of two parts: the first part consisted in gathering information related to family composition and sociodemographic conditions of the members, the second part featured questions relating to the experience of family in the PC in the family context. The interviews with family members were recorded and transcribed. The content analysis and thematic Bardin, was the technique adopted for data analysis. We apprehend this study that the PC has a significant effect on the family and among those experiences, which leaves the family more un easy is the lack of support emotional/instrumental from professionals and social networking. The study also identifies the urgent need of nursing care to be part of the family of the child with CP in order to add knowledge to the multidisciplinary team and care paid to redeem the family unit.

ABSTRACT The acquisition of independent walking is an important motor milestone and can be considered the greatest biomechanical challenge in infanthood. In the first 5-6 months of independent walking, important transitions appear in all gait parameters. One aspect to take notice is the high level of variability during this acquisition process. Based on these characteristics, this work contributed to better understand the acquisition process of independent walking according to biomechanical variables. A longitudinal study was conducted with three different assessments along a threemonth period. Kinetic and kinematic variables were analyzed. Ten toddlers of 13 months without any neuromuscular disorders participated in this study. The project was approved by the Sao Carlos University Ethics Committee (Number 013/2010). The toddlers were encouraged to walk freely on a 5 meter walkway, keeping natural speed. The Study I verified the variability in the Ground Reaction Forces (GRF) during the assessments. The Friedman s ANOVA did not reveal significant differences in the discrete variables, despite the reduction in the Coefficient of Variation (CV) of the vertical and horizontal components of the GRF. The Study II verified changes in kinematic variables, using spatio-temporal parameters and knee, ankle and hip joint angles. Once again no significant differences were found, however toddlers showed speed and cadence improvements and also reduction in the double support time and stride duration. Moreover, there was an increase in the first wave of the knee flexion. The gait experience acquired during the first threemonths of independent walking to these children was not enough to cause significant changes in the biomechanical variables studied here. However, the progressive reduction in the CV between assessments and the changes in some spatio-temporal parameters suggest progressive gait maturation.
Equivalência de estímulos e generalização recombinativa no seguimento de instruções com pseudofrases (verboobjeto)

An important issue in the field of verbal behavior is how a person understands and learns to behave according to verbal commands or instructions. The stimulus equivalence paradigm, as a model of symbolic behavior, may explain the origins of the comprehension of instructions. Following new instructions can result from the recombination of subunits of previously learned instructions. This work reports three studies that investigated questions related to instructional control. In the first two studies, the general objective was to establish pseudo-phrases (action-object) as members of equivalence classes with actions, objects and abstract pictures; and to verify whether, when employed with an instructional function, the pseudo-phrases and the abstract pictures would control the participants responding. Additionally, the studies asked whether participants would follow new (recombined) instructions. The third study investigated whether the overlapping of elements of pseudo-phrases in teaching phase would favor generalized instruction-following. In the studies 1 and 2, twelve of the thirteen participants learned the auditory-visual conditional discriminations among spoken pseudo-phrases and actions presented in videotapes and among the same sentences and abstract pictures. Probes for class formation showed that the same twelve children comprehended the sentences, relating, through equivalence, the pseudo-phrases, the actions and the abstract pictures. Similar performances were observed with the pictures, suggesting that they had been comprehended and that they could work as substitutes for (or equivalent to) oral instructions. However, none of the children followed new (recombined) instructions, although all children responded under partial control of what was previously taught (object or action). In Study 3, four participants learned auditory-visual conditional discriminations (Condition 1) among spoken pseudophrases and videotapes (each showing action-object) and followed oral instructions in the tests of the instructional control, but only one participant followed recombined sentences. Four other participants learned to follow the experimental instructions via execution of the action related to object in the simultaneous presence of the auditory stimulus and of the corresponding videotape (Condition 2), but did not present recombinative generalization. Seven of the eight participants followed new instructions in the pre-test of new training matrixes with overlapping of the elements of the sentences previously learned (that is, their responding was under the control of elements of the compound). As a whole, the results represent a systematic replication of previous results indicating that class formation could promote the comprehension of sentences and facilitate the instruction-following behavior when the sentences are used with instructional function. Regarding the development of stimulus control by subunits of these complex stimuli, the evidences were very fragile, but when it occurred, the recombination was clearly related to systematic training with overlapping of elements in different sentences, thus suggesting the relevance of this procedure as an effective teaching condition.

According to stimulus equivalence paradigm, reading consists of relations among different classes of stimuli, in which some of these stimuli are directly taught and others are derived from direct teaching. The procedure called Matching-To-Sample (or MTS) is usually used in the construction of methods for teaching academic repertoires such as reading, to diverse populations, based on the stimulus equivalence paradigm. With advances in computer, programs were developed for the implementation of MTS tasks using the computer. These programs are widely used in researches, however, broadening the potential of this technology depends on its use in applied settings such as schools. In this case, an existing question refers to which repertoires are necessary for an individual with no formal training in research and without knowledge about the theoretical and methodological assumptions of the area of Behavior Analysis to implement successfully matching-to-sample procedures to teach children in applied settings, such as school. Thus, from a systematic replication of the study in progress, developed by Oliveira (2010), this study aimed to program and evaluates a teaching program of undergraduate students for the implementation of the computerized procedure Matching-To-Sample through two studies, described below. In Study 1, participants were four undergraduate students. Initially, a set of three stimuli was used to teach participants to: (1) program AC (dictated word-printed word) training; (2) implement AC training; and (3) analyze data performance of the learner. The procedure consisted of teaching demonstration followed by instruction to repeat the demonstration. Verbal praise following correct answers and incorrect answers end of the trial and replay of the demonstration. The performance criterion was 100% correct responses. Later, generalization tests were conducted with three new sets of stimuli. Consequences for performance differentials were removed and the performance criterion was 100% correct answers. Study 2 involving three new participants and modification of the teaching procedure. It was conducted in a manner analogous to that described in Study 1, except as provided below. Before the teaching sessions, sessions were held to baseline: (1) program AC training; (2) implement AC training; and (3) analyze data performance of the learner. The sessions were performed as described in Study 1, except that differential consequences for performance have been removed. After, teaching sessions were introduced with a demonstration followed by instruction to repeat the demonstration. Correct answers were followed by verbal praise and incorrect answers within the "Retry" and a new opportunity to respond, unlike Study 1. Criterion to finish sessions was 100% of correct responses. Next, participants were presented with generalization tests. During testing sessions, there were no scheduled consequences for participant responses. Criterion to finish the session was 100% of correct responses. According to the results of Studies 1 and 2, all participants met criterion in the three phases of training and showed generalization of repertoire to news sets of stimuli. Results showed that the procedure may be used as a sound basis for the development of a program for teachers. The results suggest that the procedure may be efficient to teach teachers to implement Matching-To-Sample procedures, extending the technology derived from Behavior Analysis Applied to applied settings, 4 such as classrooms and schools. Furthermore, this study could leverage future research with similar goals.

Allelopathy is a process that involves primary or secondary metabolites produced by plants and microorganisms, which influences the growth and development of agricultural and biological systems. The intensity of plant allelopathic effects may depend on the hábitat, age and the biotic and abiotic conditions during the seasons in which they were collected. When allelopathic substances are purified and identified, they can be used to develop alternative products based on natural compounds to control weed species. The Brazilian savanna (cerrado) has very stressful environment conditions, mainly in dry periods, and should favor a greater variety of allelochemicals in Rapanea ferruginea (Ruiz & Pav.) Mez and Rapanea umbellata (Mart.) Mez (Primulaceae), which have leaves with resin canals and minute secretory glands, sparse throughout the abaxial surface, that can accumulate terpenes or tannins. This thesis hypothesis is that there must be allelopathic substances in the species of Rapanea to favor their establishment in the savanna and that they should be influenced by seasonal factors or by plant age. Allelopathy occurs by the release of allelochemicals in the environment and these may have economic importance, serving as molecular models for the production of natural herbicides, less harmful to the environment. In the first chapter, we compared the effect of plant age and season of leave collection on the allelopathic activity of aqueous extracts of R. ferruginea and R. umbelata. For this, germination and initial length bioassays were conducted using commercially bioindicator cultivated species (lettuce, tomato and onion) under the influence of the aqueous leaf extracts of adults and young individuals from wet and dry season at 10 and 5% (weight of leaf powder per volume of distilled water, g/mL). The extract of adult R. umbellata collected in the dry season showed the highest allelopathic activity and was chosen for the other studies of this thesis. In the second chapter, we compared the allelopathic activity of leaf aqueous extract of R. umbellata (10 and 5%) with the synthetic herbicide Oxyfluorfen on germination and initial length of weed species: barnyardgrass (Echinochloa crus-galli L., Poaceae), wild poinsettia (Euphorbia heterophylla L., Euphorbiaceae) and morning-glory (Ipomoea grandifolia Drammer., Convolvulaceae). In the third chapter, bioprospection, purification and isolation of secondary metabolites of agronomic interest was performed with R. umbellata leaves. Bioassays wheat of etiolated coleoptiles and germination and initial length of cress, lettuce, onion and tomato were performed under the effect of extracts of organic solvents for the direction of the compounds purification. The acetone extract was the most active and therefore was used to be fractionated by chromatographic column. It fractions were purified HPLC and Sephadex column. The isolated and purified compounds were identified by NMR1H and 13C spectra. This thesis results permit we to affirm that allelopathy is one way of the R. ferruginea and R. umbellata species to establish themselves in the savanna. The allelopathic activity of its leaves is influenced to a greater degree by the collection season (most active in dry season) than by plant age. The R. umbellata aqueous leaf extract showed distinct action than the Oxyfluorfen synthetic herbicide, being very active on the root part of the weed species while the synthetic herbicide was more active on the arial parts of these species. The bioprospection of R. umbellata leaves conditioned isolation and purification of the substances lutein and (-)- catechin. (-)-Catechin has the potential to be used as a natural origin and biodegradable herbicide.

Presently, the accelerating process of globalization has given a change of values that, unfortunately, affect the daily of Bioregional communities, resulting in both loss of biological diversity as well as cultural diversity of those communities. Thus, this study aims to reveal that the Pantanal s community of São Pedro de Joselândia still has a strong relationship with the environment to which it is inserted, as evidenced by the local culture and resident s knowledge, especially the knowledge about local avifauna, demonstrating also that such knowledge can assist in preparing of bird s inventories made by the scientific community and assist in the recognition of resident s knowledge about the Pantanal wetlands, in relevance of dialogue between local and universal knowledge. The methodology is anchored in the Bioregionalism s theories, which advocate the development of the environment surrounding Bioregional communities, taking into consideration the circumstances and the knowledge of these communities. The results allowed the construction of a local list with 162 species of birds belonging to 56 families. The identifications made by the residents were made visually or by vocalizations of the species, and the classification made in the community is linked to morphology, behavior or vocalization of the species. Furthermore, we identified the ecosystem services of provision related to species that serve as a food supplement for the community, and cultural, related to species with some symbolic relation to the residents. Finally, an educational booklet about the community of São Pedro was produced, together with community residents, showing a bit of everyday life and relationships that residents have with the wetland environment, serving as a return to the community of the results achieved during the research.

xuberant landscape, identities that are at the mercy of the historical indifference and of the hegemonic economy of the agribusiness that advances over the so‐called empty spaces are hidden. In these different environments, a rich cultural mosaic of interacting identities, that many times, are invisible or barely known coexist. With this pseudo‐invisibility, many social groups are not being attended in the elaboration of public policies. An example of this can be noticed in the policies that aim at the territorial management of the State, such as the Ecological Socioeconomic Zoning Project of Mato Grosso that did not support the different social groups that form the mato‐grossense landscape. In the attempt to overcome this fragility and give visibility to this beautiful cultural mosaic, we started in 2008, a daring proposal of building the Mapping of identities and territories of the State of MT , proposed and carried out by the leadership of the Research Group in Environmental Education, Communication and Arts (GPEA) of the Federal University of Mato Grosso (UFMT) with the important contribution of several partners. Enrolled in this project, we assumed the commitment of performing the mapping of the social groups of MT, with the aim of identifying and registering the identities of resistance. Based on the triad inhabitants-habits-habitats, we sought to understand the identity of the mapped social groups, their different rationalities and ways of life that limit the characteristics of their territories in an intrinsic relationship between culture and nature. Besides, we seek to understand how the identities of these groups are constructed, destroyed and re‐constructed due to the alterations in the habitats. In this trajectory, we elaborated a methodology called Social Map that used the narratives of the representatives of several social groups, aiming at understanding the essence of the identities that build different meanings and act in the different mato‐grossense biomes. Two seminars of Social Mapping with more than 500 participants from 54 municipalities; were held in 2008 and 2010. There were more than 70 Indigenous representatives of 19 ethnicities, of Maroon communities, pantaneiro peoples, families who were camping, settlers, family farmers, rubber‐tappers, extractivist workers, gypsy communities, affected by dams, people from Araguaia, Morroquian communities, among others. In an ethnographic approach field researches were also carried out. In this becoming of several groups and movements we expose the existence of old and new social protagonists, totalizing 52 social groups /communities/movements that added to 47 Indigenous ethnicities that resulted in a prognostic of 99 mapped identities. In the search for finding space for them, a map of the social groups was made, an important result of this thesis. In this map the identities built in traditional dimensions; of the place of culture and habitat; of labor, work and production; of the driving forces and development; and, of the choices and philosophies of life were shown and circumscribed in the territories. The expectation is that with information provided by this research, there will be subsidies for articulations, partnerships and alliances so that the social groups can be strengthened in their struggle for the protection of the State s ecosystems and be attended by the public policies. The environmental education comes hand in hand in this circle allied to the valuing of culture, in the daring idea of reconstructing the sustainable societies that re‐signify values such as environmental justice, belonging and democracy. There are loose dots and lines, but there is also, a territory of hopes that transcends this tyrant time, rescuing the weavings of the collective dreams.

The objective of this study was to develop automatic flow analyzers for the determination of pharmaceutical analytes using a micro-device based on LTCC (Low Temperature Co-fired Ceramics) and a mini-photometer as the detection system. To perform this task, the following devices were developed: 1) A mini-photometer based on RGB-LED (Red Green Blue- Light Emitting Diode) which wavelengths of maximum emission are 465, 525, and 640 nm, respectively, was used as the radiation source. A photodiode (PD) was used as a detector; 2) An optical cell for flowing analysis. A software was developed in graphic language using LabView® 7.0 in order to control and acquire analytical data. The mini-photometer for flowing analysis and software were developed for the determination of N-acetylcysteine (NAC), captopril (CAP), adrenaline (DNA), dopamine (DPN) and ascorbic acid (AAc) in pharmaceutical formulations. First, the mini-photometer was developed and used as a photometric detector. Then, a labmade valve actuator (VA) connected to a computer interface for data acquisition (National Instruments USB 6008) was used to switch on/off the solenoid valves. This interface also enabled to control the mini-photometer as well as the acquisition and processing of transient signals generated in the LTCC. In all determinations, the miniphotometer, the LTCC and the flow system with multicommutation employing threeway solenoid valves were used, except for NAC and CAP where an analyzer with manual injector was used. Solid-phase reactors were also used due to lower reagents consumption. The results from the developed system were compared with reference and validated methods (found in the literature) and there were no significant differences at 95% confidence level. The developed system with LTCC employs low volume of reagents and samples and can be used to determine several analytes in different matrices. applied in any other used (due to), along with a system of universal (able to be applied in any other application in flow) were other good features of this developed system. The good stability and sensibility of the developed mini-photometer (4 x 4 cm) enabled an adequate performance during the determinations.
