Riparian vegetation is source of wood debris in streams so variation in vegetation type promote difference in biomass and richness of these substrates, which affect composition and abundance of insects associated with submerged wood. Aquatic Coleoptera associated with submerged wood debris is pointing out to it importance in the wood breakdown. For evaluated if the vegetation type influences community of aquatic Coleoptera associated with submerged wood debris, we collected submerged wood in eight Atlantic Rainforest streams, eight Cerrado streams and we include two Semideciduous Forest streams. We applied different statistical analysis (redundancy analyses, PERMANOVA and partitioning variation) to test if the taxonomic composition in Cerrado streams was different from Atlantic Rainforest streams and to verify what cause this possible difference, environmental variables, spatial variables or both. We found 1617 organisms distributed in 12 families and 29 genus. We found two boring genus of submerged wood debris for Neotropical region, Lutrochus and Stegoelmis, which play important role to food chain of streams, due to availability of nutrients and microhabitats at wood. The results of taxonomic composition of aquatic Coleoptera associated with submerged wood debris showed differences between Atlantic Rainforest and Cerrado streams, exhibiting that the vegetation type is important factor for the composition of this community. We argued that this is because of differences in composition and structure of vegetation, which cause differences in richness and biomass of submerged wood in streams.

In this work, based on the article The Codazzi Equation for Surfaces by Juan A. Aledo, José M. Espinar and José A. Gálvez [8], we describe some applications of an abstract theory for the Codazzi equation on surfaces. This theory deals with abstract pairs of quadratic forms on a surface, in particular the so-called Codazzi pairs, for which the Codazzi equation is satisfied. Among the applications, we give a proof of an abstract version of a classical theorem due to Hopf on immersed spheres in Euclidean space R3 with constant mean curvature. Other applications are proofs of Liebmann s theorem on complete surfaces with constant Gaussian curvature in R3 and of Grove s theorem on the rigidity of ovaloids. We also study the existence of holomorphic quadratic differentials associated with Codazzi pairs. This is used, in particular, in the classification of complete embedded elliptic special Weingarten surfaces of non-minimal type in R3 whose Gaussian curvature does not change sign.

Assuming that traditional measures of diversity are rough predictors of functioning and that measures that incoporate information about functional traits are better predictors than the traditional ones, functional diversity measures are intensely used nowadays. However, whether the inclusion of functional traits in biodiversity estimation indeed increases our predictive power is rarely tested. Moreover, dendrogram-based functional diversity measures usually do not take abundance into account. By sampling a southern cerrado site in Brazil, we tested whether, when compared to traditional diversity measures, the inclusion of functional traits leads to an increased predictive power in relating functional diversity to community functioning. We demonstrated that it is possible to include abundance in dendrogram-based functional diversity, and tested whether, when compared to functional diversity as usually calculated, the inclusion of abundance leads to an increased predictive power. No diversity measure was related to community functioning, including functional diversity. Nevertheless, we showed that it is possible to include abundance in dendrogram16 based functional diversity measures, even if most indices were correlated with each other.

The desintegrinas are cys-rich polypeptides without enzymatic activity, some found in snake venoms with an adhesive motif to integrin, unleashing distinct responses. Several research groups have been studying snake venom disintegrins with focus in pharmacological applications in tumor progression and proliferation, angiogenesis, blood clotting, and osteoporosis. This work shows the results of the construction of cDNA library of Rhinocerophis alternatus venom gland, cloning and expression of ALT-C, a disintegrina-like protein, in bacterial system. The library was comprised of 812 sequences that were classified into: (i) coding for hypothetical protein or mismatched in databases (unknown) corresponding to 20.94%; (ii) transcripts for cellular process 17.86%; and (iii) transcripts coding for toxic protein with 61.21%. Among toxic proteins the SVMPs were the most abundant transcripts 58.59%. Other toxic transcripts were C-type lectins (15.56%), bradykinin potentiating peptides (11.8%), serineproteases (5.18%), cys-rich secretory proteins (2.28%), vascular endothelial growth factors (2.28%), L-amino acid oxidases (1.86%) and phospholipases A2 (1.45%). The percentages correspond to this snake venom effects, low enzymatic activity and hemorrhagic and clotting activity as main action, derived from the SVMPs, C-type lectin and serineproteases. One of the SVMPs contigs were chosen based on the similarity with ALT-C, the defined sequence was called ALT-Ch (ALT-C homologue) since there has 4 conservative substitutions compared to the previously determined sequence. The ALT-C-h sequence was used in PCR to inclusion the restriction site for BamHI and EcoRI, cloned in pGEX4T-1 and transformed into E. coli AD494 (DE3) for expression. The cell culture was grown until the log fase and induced with IPTG for 3 hours, the expressed protein's identity was confirmed by Western Blotting using Polyclonal antibody Anti-ALT-C. The construction of the R. alternatus venom gland cDNA library provides a source of interesting active biomolecules, such as desintegrinas, to pharmacological applications in pathologies involving integrins like angiogenesis, tumor progression and metastasis.

This work is based on Ph.d. thesis of R.Brooks [1]. R.Brooks develops his work in three parts, first establishes Nielsen s theory (Essential class, Nielsen s number, estimates for the Nielsen s number) for determined classes of pairs of homotopy, called _-classes of homotopy. In the second part using homology and cohomology develop an index, that associates to each tuple (f, A,B), a homomorphism L∗(f, A,B). In the third part he relates Nielsen s theory for _-classes of homotopy with the index theory of the second part. In this work we will extend to the concept of _-classes of homotopy for D-classes of homotopy, and will study the D-number of Nielsen, n(f, p,D), for (f, p) ∈ D, after that we will define an index, L∗(f, p, s(B)), with the objective to detect when n(f, p,D) > 0.

Obesity and pre-obesity have been considered as one of the major health problems in modern society, both in developed and in developing countries is the increase in rates of overweight or obese individuals. Although much is known about the types of foods that contribute to it, few results have been observed in the control of impulsivity commonly involved in food intake behavior. This study investigated whether the caloric component of food and its magnitude have control over choice behavior and preference in subjects ranging from seven to thirteen years old, with overweight and intellectual developmental delay. The research was conducted in a charity institution specialized in serving individuals with intellectual developmental delay. Two identical gums were prepared for this study, in relation to the organoleptic characteristics, differing only for the calories they contain. For data collection, we used an experimental apparatus that operated in concurrent chain schedule of reinforcement. The first link was operating on values of fixed ratio (FR- 1), followed by another scheme, also operating in FR-1. The schedules were controlled by a computer program. Choice responses in Button 1 were followed by one caloric gum in its terminal link, and choice responses in Button 2 were followed by a non-caloric gum in its terminal link. The session consisted of four presentations of the schedules. The data of interest were the responses in the initial links of concurrent chain schedules. A single subject design was applied, with the participant as his own control. The results, first, illustrated that there was no preference for calorie-rich foods, and will be considered as baseline for continuing the study, in which each of the possible variables controlling food choice could be introduced (eg, delay of reinforcing contingency , cost of response). Studies on the nature of choice and preference for non-caloric and caloric foods are important to identify and describe appropriate procedures for understanding and controlling food intake in overweight or obese children with intellectual developmental delay.

The advance of techonologies, especially the mass communication means, had approached not only the world economies, but also cultures and societies. The emergency of a called global society brings the coletivities together, and throws them into planetary orbit. It promotes a redefinition of the Nation-State and, consequently, a reflection of the traditional public sphere concept. Observing the new amplitude of communicational flows allows to observe the rising of civil society on international scenary. Its space for deliberation is related to comprehensions of international dinamic, as well to the human relations transcending national frontiers. National movements point out the recognizement of the transversality of human interests, marked by world public opinion tendencies, tied to the informational growth and the globalization process. This research intends to approach Jürgen Habermas public sphere traditional concept, revisited in a transnational dimension, once themes previously belonging to national agendas move to world agenda, establishing commom concerns, as environment and climate change.

Metacognition represents thoughts and knowledge that individuals have about their own thoughts and cognitive processes. Two basic elements of metacognitive functioning are metacognitive knowledge, characterized by awareness of the processes and skills required to perform a certain task, and control or cognitive self-monitoring, which includes judgments about the effectiveness of the strategies initially proposed, and if necessary, the establishment of new ones. Given the lack of brazilian instruments that measure this ability, this study focused on the development of items and the analysis of evidence with respect to the validity and reliability of a scale for assessing metacognition in children between nine and 12 years of age. The first phase involved the construction of Likert-style Metacognition Scale, using a six points rating scale for the respondent to indicate the extent to which he would using each strategy. During the second phase, three experts evaluated the instructions and the 70 items to verify the content validity of the new scale. These experts were university professors with doctoral degrees, and two were specialists in metacognition. The third judge, given her expertise in elaboration of scales, assessed the adequacy of the instructions for the task. The reliability analysis performed on the responses of the experts presented a 70.3% of agreement. The specialist in elaborating scales suggested some modifications in the instructions, which are incorporated into the scale. Two samples of each which led to further changes in the instructions and reduction in the number of items from 70 to 67. The factor analysis performed on large sample of 196 participants revealed the presence of a single factor denominated Metacognition , responsible for 16.84% of the variance in the scale. After exclusion of items that had factor loadings below 0.30 of items that indicated misunderstandings by the participants and similar items, the new version of the EMETA was composed of 40 items with an internal consistency of 0.90. There were no significant differences related to performance variables such as gender, school type and age of the participants. As such, the analysis of validity and reliability of the items indicated adequacy of the concept initially proposed and good internal consistency of the final version of the scale.

Aiming to answer the question: preserved streams can sustain higher beta diversity than degraded streams? We estimated beta diversity of preserved and degraded streams during the rainy season of 2009 in pool and riffle areas using as substrate bags of leaf litter of tree species Talauma ovata. We analyzed the similarity in taxonomic composition of different mesohabitats using different indices of similarity (Sørensen, Morisita-Horn and Horn) and their corresponding estimators of diversity. Our study showed higher values of beta diversity in streams degraded when estimated by the similarity indices of Sørensen and Morisita-Horn. On the other hand the Horn index indicated no differences between the streams. This greater differentiation in faunistic composition between the different streams in degraded mesohabitats seems to be related to degradation of the riparian zone which favored the largest effect of hydrological disturbance due to increased volume of water especially in areas of pool resulting in elimination of taxa and increase local the dominance of more tolerant taxa, affecting beta diversity. This study paves the way for new understandings of the effects of degradation of riparian zones in streams, because the comparison between habitats within a given stream may provide a basis to assess their state of degradation, making possible new approaches to biomonitoring.

In this work were determined and compared to mechanical, thermal and barrier of the polypropylene composites containing micropartilate and microparticulate calcium carbonate. To prepare the composites, the filler was incorporated into the homopolymer PP, with the aid of the compatibilizer PP grafted with maleic anhydride in a twin-screw extruder, producing concentrates of calcium carbonate. Were subsequently diluted in PP, in different conditions and at four different concentrations. Based on the results of mechanical tests, the condition that generated the best result was obtained with screw speed of 500rpm and 10kg/h flow of the extruder. The other mechanical, thermal and barrier were performed on samples prepared in these processing conditions and from this point forward, we evaluated the influence of the concentration of filler on the test results, as well as the particle size. In this condition, the impact resistance of nanoparticulate increased from 4.60 to 4.96 KJ/m2 concentration of 7.87% of CaCO3. As for the Tensile strength, only 0.48% of nanoparticulate CaCO3 increased from 32.8 MPa to 35.2 MPa. HDT in the gain was 12ºC with respect to the homopolymer PP and a 2.9 ºC on the microparticulate composite. The addition of CaCO3 OOT reduced as its concentration increased and the flammability, the nanoparticulate compound showed a slight reduction in burning rate with respect to the PP. Regarding ownership of permeability to water vapor, the microparticle behave remained stable for all concentrations, however, as the oxygen permeability, we can highlight the compound with 1.51%. In the nanoparticles, we can highlight the compound with which generated a 0.48% reduction to 52% of the value found for the PP, but did not produce good results with oxygen. Comparing the results we can conclude that the composite nanoparticulate has interesting properties and superior to the microparticle, depending on its concentration.

The purpose of this thesis is to demonstrate the existence of an original psychoanalytical theory of perception, a theory which subverts philosophical and psychological traditional conceptions on the matter. In order to establish and characterize this doctrine of perception not explicit in Freud s works our methodology proposes rereading Freudian texts in the light of philosophy and different schools of the psychoanalytical movement. This work follows a path that leads from an archeology of Freudian metapsychology one that enables to sketch the grammar of perception to state the intrinsically pulsional dimension of the perceptive process. As regards the grammar of perception, Freud follows a tradition that links perception to the material aspects of the trace, especially with the fundamental notion of mnemic trace . From the beginning of his work, perception is approached as related to the gramma, the letter, the character of writing. Nevertheless, the rules of this psychoanalytical grammar are particular, paradoxical, drawn on the horizon of loss and plural times, oriented by a deferred action (Nachträglichkeit). Perception is anchored in a negative dimension. As regards the erotics of perception, the true revolution of the analytical doctrine of perception consists in revealing that perception is not absolutely dependant on physiology: it is overturned, perverted, by the logics of desire. Perception is thus found at the course of this intersection, on a hybrid spot between the grammar of the image and the word and a dimension beyond them, which is erotic, pulsional.

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.
