Forest fragmentation and habitat loss in tropical regions are implicated for different organisms responses, with special attention to avian species susceptible to disturbance. They react negatively in the face of changes in their habitats, reducing population size. In this scenario, the riparian forests play an important role as refuge for many species of birds. This study aimed to survey the avifauna of two riparian forests belonging to the Batalha River, West-central region of the state of São Paulo. The birds were described according to their composition, guild structures, degree of dependence on forest quality and level of sensitively to disturbances. Altogether, the census methods applied across the paths and point counts revealed a total of 162 bird species distributed in 48 families and 21 orders, among which 98 were forests, 14 endemic to other kind of vegetation, 3 endangered, 8 near threatened 32 abundant residents and various insectivorous specialists. These results testify the important contribution of riparian forests of west-central of São Paulo state in the conservation of local birds that are sensitive to the fragmentation.

This dissertation is a revision of the post-1988 Brazilian presidentialism, analyzing the available literature. The surveys point to a conclusion that the Brazilian presidentialism has gained reasonable levels of institutionalization, contradicting many of the criticisms raised about the potential for institutionalization. This establishment was in large measure because the stabilization of the party system that has polarized yourself arround of the seven main parties, improving its internal functioning and the consistent performance in National Congress, thus minimizing the possible effects of high fragmentation and especially becoming able to provide effective support in the executive branch. This, in turn, has taken it upon themselves to use very effectively the powers and mechanisms to its disposal to enforce its agenda of government, becoming away from the conflict between the powers and the feared decisional paralysis, as predicted. Summarizing, despite his apparent problems in the post-1988, in the Brazilian presidentialism prevails an important democratic character that certainly keep the process of institutionalization of the country.

Through the synthesis conditions used were possible to exploit different variables in order to obtain different zeolitic structures, whose main were those formed from sodalitics units (LTA and FAU). From clear solutions containing water, tetramethylammonium hydroxide, sodium hydroxide, tetraethyl orthosilicate and the aluminum isopropoxide, different combinations of these reagents in molar compositions were made and obtained zeolites with structure LTA, phase mixture LTA and FAU, FAU, GIS (NaP1). In the first design, the structure LTA pure was obtained with a high degree of crystallinity in 50% of the experiments, the other 50% were obtained materials with low crystallinity (amorphous). The most important synthesis variables to obtain the structure LTA were the content of template and crystallization temperature. In other design, the results included mixtures of phases LTA and FAU, pure FAU and GIS (NaP1) and yet many of the experiments with the presence of material with low crystallinity. Using how response the ratio between the intensities of diffraction peaks related to the LTA and FAU structures, it was observed that the most significant variables to obtain the zeolite FAU were water content, the template content, the sodium content, crystallization time and aging time. FAU structure pure can be obtained when the ratio Na2O/Al2O3 is fixed at 0.06 to particular conditions of the other variables. Thus through the statistical design of experiments could verify the synthesis variables most important for the formation of these two structures.

The current research was developed at the Post-graduation Program in Education at UFSCar in a Social Practices and Educational Processes research line. This is the master's thesis in which was conducted a qualitative study in order to understand how the musicians discover themselves as music educators. The aims are to describe and to analyze the strengths and weaknesses in both professions, to understand how the family and society recognize them and how these professionals become more aware of their social role. The research also searched for understanding which social and academic practices promote the awakening of the musician toward music education. Questions, anxieties and reflections about the music return to the regular school curriculum and the current education of musicians and music educators were surveyed. The main authors of the research line helped to build a theoretical basis allowing the discussion on the research problem. The concept of experience was referenced on Larrosa Bondia (2002); the concepts of culture, pop culture and liberation were based on Dussel (undated); Education, Dialogue, Liberation, and others came from contributions of Paulo Freire (1979a, 1979b, 1992, 1993, 1996, 2000, 2001); and the concept of teaching practice was founded by Tardif (2002). The concepts of social practice and educational processes were built from the text developed by the professors of the research line. The concepts in the field of art-education were contributed by Barbosa (2009). Other references in the field of music education helped us to build the specific references, including: Penna (2005), Kater (2004), Koellreutter (1977), Fonterrada (2005). The data collection methodology used was the group interviews which promoted a dialogue among the participants. Fourteen graduated students of the Bachelor s Degree in Music at the Universidade de Ribeirão Preto, UNAERP, were interviewed. The research is organized into three chapters. The results show that the discovery of music education by musicians occurs as a result of the positive experience, of the involvement with working, and of the bond they establish with their students. We can also emphasize that the possibilities of personal and interpersonal changes that occurred during his/her professional course collaborate, motivate and encourage teachers to initiate and continue his/her career.

Studies show that when dealing with cases of abuse, health professionals have difficulties in identification and reporting. These difficulties are related to a gap on this topic on their professional training, the reproduction of cultural patterns of noninvolvement in matters concerning the family, the disbelief in the effectiveness of Child Protection Services, negative past experiences and other personal issues. Other studies have indicated the need for training programs for these professionals, pointing suggestions on what such program should contain, as well as its format, scope and professionals levels involved for this type of audience. The goal of this study was to raise awareness among professionals of the Family Health Program (PSF) about child abuse by developing, proposing and evaluating a training course to identify and report child maltreatment. The training was developed based on the guidelines described by the literature. The objectives of the training were that the professionals should be able to: a) identify the phenomenon of violence, b) identify the types of violence against children and adolescents, c) identify the signs and symptoms associated with such violence; d) identify risk and protective factors; e) analyze the myths surrounding the subject; f) analyse appropriate ways to approach victimized children; g) identify the Protective Network in the city; h) identify and analyze factors that promote resilience; i) establish a dialogue between staff and the agencies responsible for children and youth and j) correctly complete the reporting form. The study was approved by the University´s Ethics Committee. The study included two teams of reference from two distinct Family Health Units. Initially only team participed in the intervention group and a the second remained as control. The study took place in a mid size city of the State of São Paulo, Brazil. The training lasted 15 hours, divided into 10 alternative week meeting. At the end of the first intervention, the control group took part of the training, as well. Each team had 11 health professionals. The assessment instruments used were: Questionnaire on Hypothetical Cases, Child Maltreatment Evaluations in Pediatric Primary Care and Questionnaire on Family Violence against Children and Adolescents. After the health teams training a positive changes on the procedures adopted in a situation of suspected or confirmed child maltreatment, were found as well considering incresining to reporting to Protective Services. Moreover, according to participants evaluation, the training made them aware of the care involved in such cases, which went unnoticed before. In conclusion the training of health professionals to identify and report Protective Services cases of child abuse is an efficient way to maximize reporting behavior. It would be important to have Public Polities to improve services to children as a mean to prevent violence, as well as strengthening Child Protection Services.

In this work, we have studied the transport and optical properties of GaAs = AlGaAs resonant tunneling diodes with Si delta-doping at the center of the quantum well. We have studied magneto-transport and polarized resolved photoluminescence from GaAs quantum well and contact layers as a function of applied voltage and magnetic _eld parallel to the tunnel current. Three resonant peaks are observed in the current-voltage characteristics curve and are associated to the resonant tunneling through the bound state of a shallow donor impurity in the quantum well (donor-assisted resonant tunneling), the electron resonant tunneling through the _rst con_ned state in the quantum well and the phonon-assisted tunneling. The contact layer and the quantum well emissions were investigated as a function of applied bias at 15 T. The optical emission from GaAs contact layers shows evidence of highly spin polarized two-dimensional electron (2DEG) and hole (2DHG) gases which a_ects the spin polarization of carriers in the QW. The quantum well (QW) photoluminescence presents strong circular polarization with values up to 85% in 15 T at low applied voltages (at the donor assisted resonant tunneling condition) and for low laser intensities. Our results may be interesting for the developing of new voltage-controlled spintronics devices.

Hot tensile test data were correlated with creep data, in commercially pure copper, using a recently proposed criterion for the analysis of these two kinds of tests at high temperature. The criterion considers the equivalence between the following parameters in each case: deformation rate, ultimate tensile stress, time taken to reach the ultimate tensile stress, in tensile tests respectively with: minimum creep rate, applied stress, rupture time, in creep tests, at a certain test temperature. In tension, the material was tested in the temperature range from 250 to 550°C, using constant deformation rates varying from 1x10-5 s-1 to 0.208 s-1. In creep the temperature range varied from 250 to 525°C with stresses varying from 7.5 to 60 MPa at constant load. The conversion of the hot tensile data to creep data made possible the common analysis of all the results according to typical relations pro-posed by several authors in creep literature: Norton, Arrhenius, Zener-Hollomon and Monkman-Grant, with determination of the corresponding parameters in each case. The data were also analyzed according to four different parameterization methods commonly mentioned in the traditional creep literature for data extrapolation: Larson-Miller, Orr-Sherby- Dorn, Manson-Succop and Manson-Haferd. With exception of the Larson-Miller method, all the attempts for data correlation of hot tensile and creep tests produced excellent results. In addition to the correlation between these two kind of tests, a detailed analysis of the results of hot tensile and creep tests was carried out, separately, with discussion of the mechanical behavior of the commercially pure copper in each case.

The sense of pleasure that arises from engagement in activities is of fundamental importance for the wellbeing of the elderly. Studies indicate that involvement in pleasant activities acts as a mediator variable in the prevention and treatment of mental disorders, in addition to predicting physical and psychological wellbeing. According to the literature reviewed to develop this study, research on this topic in Brazil is just beginning, and there is not yet an instrument, validated for use in Brazil, to evaluate the involvement of elderly people in pleasant activities. An American instrument was located in the international literature (The California Older Person s Pleasant Events Schedule - COPPES), which evaluates the frequency with which elderly people are engaged in pleasant activities and the degree of pleasure they associate with each activity. Based on its strong psychometric qualities, the inclusion of a measure to determine how each respondent felt about each activity, the ease with which the scale can be understood, and given that the items appeared to be relevant for the Brazilian culture, this instrument was selected to submit to the first steps of a cultural adaptation process, for use in Brazil. The primary objective of this study was to conduct a transcultural adaptation study (semantic equivalence, conceptual equivalence, cultural equivalence, idiomatic equivalence, operational equivalence and measurement equivalence) to prepare this instrument for use in Brazil. The main results indicate that: a) the semantic equivalence of the translated versus the original version is satisfactory; b) the items are relevant to the Brazilian cultural context and evaluate the dimensions identified by the original instrument; c) the indicator of internal consistency for the frequency and pleasantness subscales varied between very good and excellent, providing strong evidence for the internal validity of this scale; d) the frequency subscale scores were significantly correlated with the depression scores, indicating good external validity for the adapted version of this instrument. Hopefully, the new version of this instrument will contribute to research, planning, and the evaluation of preventive intervention strategies focused on promoting the wellbeing of the elderly, in Brazil.

Cette recherche de doctorat est le résultat d'un projet plus vaste intitulé «La Question de la Mort de l'Homme et de la Psychologie selon Michel Foucault». Ce projet a l'objetif d'examiner la formulation, les facteurs et les conséquences rapportés aux différentes démarches utilisées par Foucault dans ses critiques aux «anthropologies», figurées dans la trajectoire des textes publiés pendant les années 1950 et 1960. La question principale est le problème «anthropologique»: dans les textes parus en 1954, Foucault a entrepris un double projet de contestation et fondation des sciences humaines; le jeune philosophe essayait de corriger les perspectives considerées par lui comme des perspectives erronées, pour en établir une nouvelle anthropologie finalement rigoreuse. Par contre, d'une façon relativement vite les projets de fondation ont eté remplacés pour des suspicions et donc il y a eu un changement de la façon d'énoncer le problème anthropologique: au lieu d'être «solution», la question anthropologique commence à devenir un domaine plein de problèmes. L'essay de fonder donne place à un ensemble d'analyses qui dénoncent plusieurs engagements historiquements faits pour les connaissances anthropologiques. La recherche realisée essaye d'analyser ce passage de la «solution» au «problème», en croisant la lecture de certains matériaux: les textes publiés par Foucault pendant les années 50 (et quelques textes des annés 60), les débats contemporains et les discussions sur lesquelles ces textes ont essayé d'entrer, et aussi quelques notes écrites par Jacques Lagrange pendant les cours donnés par Foucault à l'Ecole Normale Supérieure depuis 1953 jusqu'à 1955. Le croisement de références a l'objetif de voir le contexte des problèmes probablement vus par Foucault dans les textes de 1954, et le chemin parcouru par lui, jusqu'àux questions enoncées dans les textes de 1957 et l'écriture à Uppsala de la thèse principale sur l'histoire de la folie.

Prospecting for cellulose-producing fungi is one of the possible strategies for obtaining the necessary enzymes to hydrolyze the lignocellulosic material and to contribute to the viability of cellulosic ethanol production. Among the different biomes, the Amazon represents a potential source of cellulolytic fungi due to its unique soil and climatic conditions that favor the continued degradation of the biomass of the forest undergrowth. In this context, the objective of this study was the isolation and selection of fungi producing complex cellulase present in the Amazon biome with high efficiency through the process of solid-state fermentation (SSF) of 100 soil samples collected at 50 different points of Reserve Embrapa Eastern Amazon, in Belém - PA. After isolation of fungi, a total of 110, they were transferred to plates containing crystalline cellulose (Avicel) as sole carbon source for selection. Of these 110, 10 fungi were selected that showed the highest growth. The selected strains were grown at 35 ° C for 120 hours in SSF, using as a substrate for a first selection of strains producing endoglucanases, wheat bran with 60 % humidity. The two fungi had higher enzyme production in wheat bran, Aspergillus fumigatus (P40M2) and Aspergillus niger (P47C3) were evaluated in several other substrates, with different percentage of humidity. In these other substrates, has also evaluated the production of endoglucanases, Fpase, xylanase and β- glucosidase.The fungus Aspergillus fumigatus P40M2 showed, in general, the best production of these enzymes. So, finally, the enzymes produced by Aspergillus fumigatus P40M2 were characterized optimum pH, optimum temperature and thermal stability, and their bands of activities identified by electrophoresis (zymograms). The extract obtained by the fungus is characteristic thermophilic and acidophilic being very important for hydrolysis of biomass to ethanol production.

The objectives of this work were the benthic macroinvertebrate community characterization from Itupararanga Reservoir, High Sorocaba Basin, SP, Brazil and the identification of the main abiotic factors wich affects the structure and distribution of those organisms. Samplings were taken with Van-Veen grab three times (cumulative samplings). The samplings were taken at three reservoir‟s zones: riverine zone, transitional and lacustrine ones and at two regions: litoral and central ones. Furthermore, it was taken samples during the wet (December 2009 and February 2010) and dry seasons (June and August 2010). The dissolved oxygen concentrations, electric conductivity, pH, transparency and depth near the bottom were reccorded in situ by using a multiprobe and Secchi disc in all sample points. With the objective to verify witch environmental variables would be the most important for the benthic macroinvertebrates community characterization, a correspondence canonical analisis (CCA) was done by the main taxa density logarithm and the water and sediment variables data matrix. The total number of reccorded taxa was 28. The Diptera family Chironomidae was the richest group (19 taxa). The Tubificinae (Clitellata, Naididae) were numerically dominants during the wet season and the Chironomidae (Diptera) were it during the dry one. Similarity analysis was performed in order to test the spatial heterogeneity hypotesis even in the longitudinal either in the transversal directions and the seasonly effects over the community. The results points to the occurrence of the spatial heterogeneity in both directions. So the reservoir diverges either in riverine, transitional and lacustrine zones, and central and litoral regions. The riverine zone is more distinctive than the others. This zone is characterized by having high nutrient concentrations (even in the water, either in the sediment) and coarse sediment. Moreover, the characteristic taxa are: Limnodrillus hoffmeisteri, Branchiura sowerbyi and Chironomus sp. It has high density values and dominance when compared to the other zones. The transitional and lacustrine zones presents some more intense transversal heterogeneity with more rich and diverse communities near the margins. It was noticed that the benthic macroinvertebrates responses to spatial gradient of environmental conditions in both senses, the longitudinal, and the transversal. Factors associated to environmental impacts and natural factors like granulometric sediment composition or depth can be determinants to the structure and composition of the community. The Itupararanga Reservoir is in eutrophication process and the riverine zone is the most affected area because it receives more directly the possible headwater impacts

In classical Physics, the motion of an electrically charged particle is affected only by the presence of a magnetic field if the particle enters a region of space in which the field is present. Meanwhile, in quantum Physics, a charged carrier can be affected by the electromagnetic vector potential ~A, even in regions where the magnetic field ~B is not present. This surprising contrast between classical and quantum Physics has been experimentally proven in several beautiful experiments in semiconducting, metallic and superconducting material systems, and has been called Aharonov-Bohm effect. More recently, however, several theoretical works have discussed the plausible existence of this effect even for neutral particles! In this PhD Thesis project it is shown the first clear experimental observation of the Aharonov-Bohm effect in neutral excitons in InAs quantum rings. Signatures of this effect appear as oscillations in the intensity of the photoluminescence emission bands with increasing magnetic fields and also depending on the dimensions of the quantum rings. These oscillations are affected by the uniaxial strain field due to the piezoelectricity of the asymmetric InAs rings, as revealed by the atomic force microscopy, transmission electron microscopy images and X-Ray Diffraction measurements using synchrotron light. A theoretical model that describes the behavior of the excitonic interference pattern and its modulation with temperature and uniaxial electric fields has been used for the interpretation of the experimental data. The detection of AB oscillations mediated by electron-hole pair correlation is a fundamental quantum mechanical effect that will trigger further studies in this area of fundamental physics as well as technological applications.

This paper reports the synthesis of gels derived from cellulose acetate, degree of substitution (DS) 2.5, through by esterification and crosslinking reactions between hydroxyl groups and acid dianhydride benzene- 1, 2, 4, 5-tetracarboxilic (PMDA). After the synthesis of gels, they carried out as substrates for adsorption of Cu+2. The characterizations were performed using the techniques: TGA Analysis spectroscopy infrared (FTIR), back titration to determine the degree of substitution (GS) of cellulose acetate and atomic force microscopy (AFM). The gels were synthesized with the stoichiometric following ratios (PMDA/OH): 1:1, 1:1.5, 1:3 and 3:1. Confirmation of the esterification reaction was possible by analysis of FTIR and TGA and confirmation of the adsorption of copper ions was possible through the analysis of TGA where it was observed by comparing the curves of the gels without copper ions adsorbed to the curves of the gels with copper ions adsorbed. Was obtained by an adsorption isotherm of copper ions based on the Langmuir model. The results of determination of cross-links through the theory of Flory-Rehner showed that the crosslink density was higher in the gel synthesized with excess PMDA and lower in the gel synthesized with 1 mol of PMDA stoichiometry: 3 mol of free OH.

Social indicators regarding education and employment relations in Brazil indicate that the inequalities are even more critical when the analysis is done from the ethnic-racial perspective, showing a situation of obvious disadvantage for the black population. However, the literature has shown that education is traditionally one of the main tools to promote social and economic rise of blacks. Thus, various higher education institutions have implemented the system of quotas, what results of the demands of the Brazilian black movement. Therefore, this research sought to understand the relationship between blackness, education and work, from the perspective of Black college students. The objective was to study the social representations that have UFSCar`s Black students on entering the public university system through reserve places, the course and chosen profession, and the inclusion and / or stay in the labor market. Specifically, we sought to analyze the Affirmative Action Program (AAP) of UFSCar, its proposals, policies and strategies; knowing the the socio-economic students features, especially those related to school life and work; the social representations of students about their training and entering the labor market; and finally, discuss the impact of the relations established in the university context on the ethnic-racial students. Individual interviews were conducted with 13 black students, who entered at UFSCar from 2008, through the system of quotas or not. In addition, group interviews were done with the students individually interviewed. It was possible to examine the relationships between the sense of belonging, ethnic-racial identity and representations that are engendered on race relations and affirmative action. We realize, therefore, Black students who identify themselves and claim themselves as Black, participants of assertive groups, engaged in racial discussions, and also identify themselves as reservists entering the vacancies for Black students. And there are those for whom race and ethnicity are not salient elements in their identity, do not share affirmative groups, and experience difficulties to assume themselves as freshmen at the reservation of seats for blacks. The representations about the implementation of quotas for Blacks are taken as something positive, because of the belief that they allow the entry of Blacks in the university; allow the entrance of the disadvantaged people; and reduce inequality. The seizure of this policy as a negative due to the representation of that institute such measures: assume the inability of Blacks; brings constitutional complications; shifts the focus from the real problem is education based, breeds prejudice, creates inequality, and finally, regard to the difficulty of defining who is Black in Brazil. The same relationships and forms of representations were found regarding the quotas for blacks in the labor market. We realized that those students who have an affirmed ethnic-racial identity represented the relations between being Black, higher education and the labor market in a more critical and proactive way. Thus, students whose ethnic-racial identity is not presented in a manner so prominent, represented these relationships in order to deny the existence of racism and in order to minimize the very affectation in a context of racial discrimination, which is pegged to the contrariety of affirmative action in about higher education and in the labor market.

Studies have shown that inappropriate parenting styles are developed by learning parental behaviors modeled by their own parents. Furthermore, parents with a history of childhood aggression tend to continue struggling with social, behavioral and health problems, as well as their children. Thus, interventions are necessary so that parents can learn positive ways to set limits, preventing child behavior problems. The Projeto Parceria (Project Partnership) is a Brazilian parenting program which mixes Psychotherapeutic (Unit 1) and Educational (Unit 2) components to mothers with a history of domestic violence to prevent behavior problems in children. The objective of this study was to compare the efficacy of three different intervention procedures in terms of mothers well-being and sense of parental competence: a) Unit 1 followed by Unit 2, b) Unit 2 followed by Unit 1, and c) Unit 1 and 2 done simultaneously. Nine mothers with history of violence participated of the study and their 4-12 year old children. The intervention was based on both Projeto Parceria manuals. Instruments of data collection involved: Inverview With Women Victims of Domestic Violence, at the first session; the instruments Beck Depression Inventory (BDI); Child Abuse Potential Inventory (CAP) and Parenting Styles Inventory (Inventário de Estilos Parentais) applied at the pre-test, post-test and follow up phases; a Daily-Record of Wellbeing and Parental Competence Sense, collected weekly, and and Evaluation by the participants, at the last session. The project was approved by the University s Research Ethics Committee, and the initial screening of participants took place. The Interview was conducted to compose three groups evenly, each comprising one type of procedure. Subsequently, data collection and intervention took place, in which the sessions were conducted individually. The study was conducted at the University and lasted 20 sessions. It was utilized a non-randomized clinical trial with intra-group comparisons over time as Research Design. The data from inventories were analyzed by the JT Method, which evaluates the Clinical Significance and Reliable Positive Changes of instruments scores. Furthermore, data from Daily Records were analyzed using frequency charts and the Evaluation of Participants by Content Analysis. Results showed more positive indicators throughout the groups scores, when compared pre-test, post-test and follow up phases, and the group which comprised Unit 1 and Unit 2 simultaneously showed best results. All participants evaluated the Project in a positive way. The present study has achieved its objective, which was to compare the efficacy of three different types of intervention procedures to mothers with history of domestic violence, and it has indicated the one which mixes both procedures simultaneously as the most effective. Participants adhesion to the program was excellent (100%), which is rarely found in women with such profile. Limitations were found in the study that could be involved controlling the variable severity of violence experienced by participants, as well as the inclusion of other informants in data collection measures. In conclusion, it is suggested that Projeto Parceria incorporates the referred procedure and it should be replicated at other institutions that support women who are victims of violence to maximize its adoption as Public Policy.

Friedrich Schlegel is inserted in the philosophical landscape know as German Idealism, precisely the reflection on the idea of system. Although his writings and reflections do not seem, at least to his contemporaries and first commentators, not appreciate the systematicity, careful consideration may show us that the issue is the definition of the idea of system. It this understanding is lacking in his contemporaries and critics of the nineteenth century. But what lies behind their efforts is the understanding that the very transcendental philosophy requires that the system design to be rethought. It is this effort translated into the statement that every system should be original an individual who can perform effectively and historically transcendental idealism. It is this requirement that binds directly to the question of form philosophy, an issue that we try to think here. One can not speak more in creating the system, but of creating a the individual system, for if the reason is one, it is expressed in various ways individuals. The totality is expressed in the idea that philosophy is a work in progress and collective, infinite progressiveness in constant exchange, in which efforts are individuals creations of individual systems, forming the same whole and the whole history of philosophy. If the form of philosophy is infinite which in itself contains an infinite number of beginnings, we can not expect to find a system that is above the individual, the individual genius of each. The harmonious unity of this requirement is developed on the plane of culture, in which all forms must be unified, and the individual level, which should now also be fully, man and philosopher, must be a philosophy that does not separate the life of the existence of philosopher.

Was carried out the phytosociological survey of understory of remaining semideciduous forest located at Federal of São Carlos University campus Sorocaba, São Paulo State, Brazil. The goal of this study was to analyze the structural and floristic composition of the understory. Were identified 129 species from 41 botanical families, of these four threatened species and four exotic species. The species were identified in ecological groups as pioneer species (P) and non-pioneer species or latter species (NP), and as canopy species (D) and understory species (S). The families with highest importance value (VI) were Myrtaceae, Euphorbiaceae, Fabaceae, Sapindaceae e Meliaceae, and the species were Actinostemon concepcionis (Chodat & Hassl.) Hochr, Mollinedia clavigera Tul., Eugenia pluriflora DC, Cupania vernalis Cambess., Protium heptaphyllum (Aubl.) Marchand, Trichilia elegans A. Juss., Piper amalago L., Enterolobium contorstisiliquum (Vell.) Morong, Endlicheria paniculata (Spreng.) J.F. Macbr, Matayba elaegnoides Radlk. From the total species collected (129), 77 are canopy species, 29 understory species, and 19 were not identified. As for the ecological groups, 41 species were identified as P, 65 species as NP and 19 were not identified. Among the 77 species of canopy, 38 were collected in previous study on the composition of the canopy. The results attest that in the future, the composition of the canopy will be partially changed, with the possibility of bigger richness, and with more NP species proportion. The results permits to say that these small remaining of semideciduous forest are in intermediate sucessional stage and are important to biodiversity regional conservation.

In this work, we have studied the spin polarization of carriers in n-type resonant tunneling diodes (RTDs) of GaAs/AlGaAs which incorporates a single layer of InAs selfassembled quantum dots in the center of the GaAs quantum well (QW) grown on (3 1 1)B oriented GaAs substrates.We have performed electrical and optical measurements in the presence and absence of magnetic _eld. The spin-dependent carrier transport in the structure was investigated by measuring the left- and right-circularly polarized photoluminescence (PL) from InAs dots (QD) and contact layers as a function of the applied voltage, laser intensity and magnetic _eld up to 15 T. Under laser excitation, photogenerated holes tunnel through the QW and can be captured by the QDs and eventually recombine radiatively. Due to this fast carrier capture process, the QD photoluminescence will be very sensitive to the resonant tunneling condition and consequently to the applied bias voltage. We have observed a clear correlation between the current voltage characteristics curve (I(V)) and QD PL intensity for both circular _+ and _�� polarizations even though the spin-splitting of the QD PL emission is negligible and does not show any appreciable variation with the applied voltage. We have also observed that the QD circular polarization degree is always negative and that its value depends on both the applied bias voltage and the light excitation intensity. Our experimental results are explained by the tunneling of minority carriers into the QW, carrier capture into the InAs QDs, carrier accumulation in the QW region, and partial thermalization of minority carriers. The observed control of spin polarization of carriers by light and bias voltage may be explored to design new devices for spintronic applications.

The main purpose of this thesis is to approach the Sistema de Vigilância da Amazônia [Amazônia Vigilance System, SIVAM] as part of the military strategy for establishing Brazil as a power/leadership in South America. Because this strategy Brazil had to pay a high price for the world superpower asset and, by this way, the Brazilian militaries kept in force their politic power, their status quo, remains of the dictatorship era in face of a civilian regime. The referred asset can be realized as in effect since the very moment of the Air Force Department establishment, which happened at the same time of the creation of the Brazilian Air Force (FAB) during the Second World War and its research institutes Air Force Technology Institute (ITA) and Air Force Technology Center (CTA) , which had the purpose to raise and prepare critical mass for the later development of aeronautics. By the end of the Second World War Brazil dismantled its small, although important, aeronautics industry, which had many years of experience in aircraft construction. All the researches and experience were thrown away because lack of investments in this industry, result of the Brazilian government option for buying the French and American war leftovers . National interests were put aside with this attitude because the alignment with the United States would provide access to power and reputation for the Brazilian military elite, reason why it was essential to turn the country into a sub-hegemonic power in South America. It happened a similar process with the SIVAM when it was bought technology for its project and not used technology that could be developed inwards by Brazil. Brazilian militaries established the SIVAM with a nationalistic speech that had in its terms the preservation of the sovereignty and defense of the national territory. However, the praxis was contradictory since it revealed authentic the critics made against the SIVAM as an inefficient and outmoded system during its development. This study intends to make considerations in order to offer a possible explication for this attitude onto the specific case of the SIVAM.
