This present dissertation, structured in the methodology of well-known research as Didactic Engineering, it presents the development of an unpublished class for the teacher on combination analysis in the High School. The objective of this work is to elaborate a didactic material that aids the students in the learning of some concepts of combination analysis in a significant way. The elaborated didactic sequence is inserted in the telephony context and it approaches the current subject on the increment of the 9th digit in the numbers of cellular of the area of the State of São Paulo with code of area 11. The whole sequence was thought so that the student will be the protagonist of its learning, making observations, you conjecture, debating with the colleagues, manipulating materials and solving the problems proposed in the leaves of activities in an autonomous way. The didactic sequence was applied for two groups of 2nd year of the High School in the School Educational Center SESI Bragança Paulista. For they accomplish the activities, the students were divided in groups. All the sheets of activities accomplished by the students and the registrations of observations facts by the teacher during the application of the activities were good as tools to verify the objective plans were reached.

This work aims to assist the Geometric Progression Content Learning, developing educational material supported by research methodology called didactic engineering. We developed an instructional sequence based on a problem situation, in which students, by providing a simulation of a polluted river, should predict the time needed for the de-pollution to occur and develop a mathematical model in order to explain this phenomenon. The work was applied in a Ninth Grade classroom (Junior High School) in the State School called Victor Maida in Ibitinga with 29 students divided into trios. These trios remained together until the end of the application of the instructional sequence, which lasted five days. The sequence contained about 60 questions, which were formulated into a form with which the student could act autonomously, with minimal teacher intervention. Finally, this work was based on the collection of results in the analysis of priori and a posteriori of the responses provided by the teams, in order to check the results obtained.

The Chronic Noncommunicable Diseases are a major global public health challenges , and are determined mostly by the association of modifiable risk factors , such as nutrition . It is believed that the use of functional foods with antioxidant properties can positively affect the incidence of such diseases. Given this context highlights the Acai ( Euterpe oleracea ) , which features in its pulp components with the ability to inhibit or reduce oxidation processes generated by free radicals in the body . Thus , this study aimed to evaluate the effect of the consumption of the drink acai in glucose and lipid profile of Wistar rats . For forty- five days 12 Munich- Wistar rats ( Rattus norvegicus ) adult females with an average weight of 250g were divided into two groups ( Acai and Control ) received water and feed ad libitum to except the group that had the Acai replaced by drinking water Acai . At the end of the experiment the animals were anesthetized and euthanized . Blood samples were collected for analysis of biochemical parameters (glucose , cholesterol , triglycerides and blood count ) and tissue samples for histological analyzes . In the analyzed variables , even without showing statistically significant differences , descriptive results showed the maintenance of body weight and glucose and lipid reduction , and increase in some blood components relevant group Acai . Thus Because the population growing interest in consuming food which prevent diseases , promote health and improve the quality of life, it is suggested that new experimental models are implemented so that the beneficial effects are enjoyed arising from the consumption of açaí.

In this paper, I intend to report the experience of implementing an activity in some classes in a public school of the city of Ribeirão Preto, state of São Paulo, where it was made an approach to the subject "Notable Points of a Triangle" by using the software GeoGebra like as a tool for teaching and learning. The aim is to analyze students' reactions and the interaction of the same at the presentation of the content using this software. Also a comparison of the progress is made with regard to student learning through the production and execution of activities, consisting of scripts/walkthroughs. The methodology used is the didactic engineering. Working in pairs, due to the limited amount of computers in the computer lab of the school, improved academic relations between some students, arising naturally an exchange of ideas and awakening a spirit of collaboration in a very healthy learning space. At the end of the study the author concluded that activities using computing resources as an educational tool optimizes the process of teaching and learning.

Reactive Oxygen Species (ROS) are generated by the incomplete reduction of oxygen during metabolic processes, exposure to external agents and as a secondary response to several diseases and when in excess, can cause injury to tissues and cells. During the evolution process, cells have developed several antioxidant mechanisms. One of such mechanisms encompasses the peroxiredoxins (PRDXs), which are highlighted for their abundance and high reactivity with their substrates. In humans, six different PRDXs have been described as located in different cellular compartments. In erythrocytes, PRDXs, particularly PRDX2, is the third most abundant protein, indicating its possible role in the cell development and their maintenance. However, there are few studies connecting these proteins to erythroid diseases, especially in hemolytic anemias, that have a high ROS production, such as beta thalassemia and sickle cell disease (SCD). This study evaluated the role of PRDXs in reticulocytes of patients with the diseases described above, compared to reticulocytes of health blood donors, using Real Time PCR and proteins will be analyzed by Western blot. Our results showed that the levels of transcript and PRDX1 protein were increased in BT patients and decreased in SCD. The PRDX2 transcript showed no differences in both diseases but in western blot analysis a decrease in PRDX2 protein was observed in SCD, indicating a possible pos transcription regulation process for this gene in SCD. The levels of PRDX5 transcript did not present difference in any of the diseases. A reduction in mRNA and protein levels for PRDX6 was observed in BT and SCD patients. Besides its action in the detoxification of ROS, PRDX6 acts also as a phospholipase A2 regulating the phospholipid turnover at the cell membrane. The decrease of this enzyme found in both patients could indicate that the cell membrane of the erythroid cells were not renovated leading to hemolysis observed in these patients. This is the first study correlating gene expression of peroxiredoxins in these hemolytic anemias The results could contribute in better understand the role of these protein and in a identification of new targets that could help in the management of diseases and improve the survival of these patients.

In this paper we propose a learning process using as a theoretical base called Didactic Engineering. Our proposal is to develop content from the flat geometry of a problem related to kites. Using as a theoretical framework Didactic Engineering Could explain some didactic variables allows us to have some control over the process of teaching and learning. The proposal is aimed at students from sixth grade of elementary school, but an analysis of the potential of working with the kites to develop content of geometry shows that it is possible to make adjustments to work with students from all levels of basic education.

The requirements imposed by the new applications presents great challenges to the computation. There is not a perfect computer architecture, capable to attend to all the requirements. The parallel and hybrid computer arrangement rise as a solution to this scenario i.e., the CPU-Coprocessor pair arrangement can form a specialized computerized instrument for a special application task. This doctoral thesis proposes a parallel and hybrid computational platform denoted CoP-WS, that uses the interoperability technology known as Web Services. As coprocessor it is used the graphic processing unit, known as the GPU, functioning recently as parallel thread level processing of general use applications. The platform test of feasibility was inspired in radio astronomy, and it has been implemented two applications: a complex correlator of signals provided by a radio interferometric arrangement, and a flare recognition system with a solar radio interferometer image. Both processings can be inserted in the context of pipeline execution, using sufficient configuration of CPU-GPU pairs, having on one side the interferometric arrangement antenna signal input and in the other side the result of the solar flare recognition. The obtained results of the both applications show the feasibility of the CoP-WS platform, for greater volume of data being processed in quasi real time. In the case of the correlator the average processing time in each integration period was around 160 ms, and in the case of the solar flare recognition, 48 ms for each solar disk image.

The number of Building Companies that searches for a certification of their Quality Management Systems (SGQ’s) has risen in recent years, focused mainly on ISO 9001 and PBQP-H. The same trend has been occurring with regard to Management Systems of Environmental, Safety and Health at work in view of the current global socio economic outlook. Although companies suffer a number of difficulties during the process of implementation and certification of SGQ’s and several works in the literature have already studied about that subject, not much is known upon those difficulties of SGI’s (Integrated Management System) implementation, as well as the rate and reasons for dropouts implementation and recertification of those systems, especially in construction. Therefore, the present Study has as objective to evaluate the level potential of implementation of Integrated Management System (SGI’s) covering Quality, Environment, Safety and Health at work at Building Companies that have ever had a Quality Management System (SGQ) implemented. As methodological proposal, it was used the available literature for the preparation of a compatibility matrix among reference standards (ISO 9001, SiAC (2012), ISO 14001 and OHSAS 18001) and the checklist containing the items (requirements and criteria) most relevant to the implementation of SGI’s. Also were developed quantitative indicators which that do references for the degree of implementation of SGI's. The research was conducted in the form of study case, as a way of method validation, from ten civil work of a medium size Building Company. As results, some hypotheses initially proposed was validated in the research that there are significant differences in the implantation potential of SGI's in civil work in the same organization, in addition, it was possible to find that distinct phases of execution of civil works influence about the potential of adherence into implementation to one SGI. The indicators established show as an important tool for the building companies to mark out to achieve the SGI. The elaborate method contributes to the advancement in construction with regard to implementation and maintenance of SGQ’s and, preliminary, of SGI’s. Besides trying to contribute to a better understanding of the evolution of quality, environment, safety and health at work in construction, this Study longed to highlight the benefits and critical issues, not only for the implementation of SGI's, but also for their maintenance and viability in the sector.

The object of this work is the Orkut as a mean of politic socialization. The goal is to analyze the role of new communication and information technologies, specially the Orkut communities Government and Politic , to identify if there are any contribution for expansion and strengthening of a democratic political culture. Our hypothesis is that the Orkut, faced with the possibility of virtual communities creation and discussion referring to political issues, end out creating a public space which corroborates as an agent of political socialization, contributing to amplify politic discussions and for democratic politic culture consolidation. The criterion for selection of communities related to political issues in the Orkut was realized focusing in the diversity of political issues positioning, such as support, rejection and evaluation about politic and democracy. The methodology for this analyze correspond to DAIA criterion , once this criterion is not limited only in thinking communication in terms of instrumentalization and technique, but as a process of social relationship. In this way, we aimed trough this Orkut study, mainly of its communities, to investigate the role of NTCI s in the consolidation of a democratic politic culture and to contribute for the investigation about digital democracy in democratic process.

Graciliano Ramos and Cândido Portinari were friends, but they had something in common that bound most strongly: the desire to express in their works the authentic Brazilian man, the worker and the migrant in their daily lives. This research aims to show how the works of Graciliano and Candido Portinari are close, not only as a social content and theme, but mainly as a form, style and technical resources, as the verbal and visual language are intimately linked as modes of representation. The rapprochement between Graciliano and Cândido Portinari, between the books São Bernardo, Vidas Secas, and the frames Café, Lavrador de café, Retirantes and Criança Morta, aims to demonstrate how the life and work of these artists intersect, in order to represent critically the reality of the time, through a dialectical analysis of form and content, combining text and context in levels of interpretation, according to the hermeneutic proposal of Frederic Jameson in the political unconscious (1982) and the principles of visual semiotics. To achieve this goal, we consider the history of each narrative, structural components, linking them to the historical context of the country at the time. Thus we examine how each represents a social issue: the contradictory reality of Brazil, a country that keeps living archaic modes of production with the arrival of Modernism and Capitalism; antagonistic classes of this society, exploiters and exploited, farmers, migrants, landowners, the government; and alienation/reification that they are submitted, direct consequences of this system. The analyzes are performed with dialectic dialogue, form and content, text and context in reading the social content of his compositions. That is, we analyze how they say what they say about this fundamental aspect of socioeconomic and political organization of the country. Thus, through the analysis we confirm why Graciliano and Portinari are considered realistic and social critics, as such works make use of realism and expressionism as technical resources to bring about awareness of the real and present in the political unconscious subtexts, which allows to conclude from the comparison made that the connection between them, the analogy between literature and painting produced, is stronger and larger than the gap.

This research investigates the contributions for changes (or not) in the pedagogical practices of teachers of the early years of basic education stemming educational processes triggered in training courses relating to ethnic-racial theme. From the implementation of the law 10.639/032, topics related to the history and culture african- Brazilian and African became compulsory in the curriculum of public and private networks, which creates demand for conducting continuing education courses for teachers of different levels of education in these operating systems. Thus, were invited to participate in this study, black and non-black teachers in the early years of basic education who have participated in continuing education courses related to ethnic-racial theme. The research data were collected through in-depth conversations held with these teachers. The relevance of this study to the field of education is confirmed by the possibility of reflection on points that continuing education courses contributed or not to change the practice of these teachers, issues that need to be rethought in formulating future courses as well as the influence of subjective questions pertaining relating to the experiences of teachers and influence the understanding and coherency of the theme.

Orchidaceae is one of the largest and diverse families of angiosperms, that is in almost every type of habitat, except tundras and deserts. They are considered of great ornamental importance, the genus Phalaenopsis has received a great prominence having increaed and its production enlarged in the Gross and inner market This way, the Brazilian floriculture market has a great demand in seedling production, requiring more studies and researches involving biotechnologycal techniques from the development of vases and containers on a prepared substrate, propagation techniques and acclimatization. And with in vitro culture, it is possible that the desirable plant coul be multiplied through several sucbultures, which enables an earlier and new cultivation available more quickly for commercial use. The luminosity is another factor that is gaining prominence in the productivity of orchids, the fact that the quality of light affects directly the growth and development of plants grown in vitro and/or ex vitro. The present work had as objective to anlyze the growth of in vitro and acclimatization in the two cultivations (cv. 6323 and cv. 6546) of orchid Phalaenopsis amabilis Blume, under different lighting spectra. Inicially it occurred the sowing the seedling in the cultivation enviroment MS that were enveloped with different cellophanes: yellow, blue, Green, red, and white. After 60 cultivation days it was performed an statistical evaluation on the seedling. Afterward, they were put in collective vases to the phase of acclimatization, and those ones stand for more three months. Through analyze the biometric data it can be observed that the growing in vitro and ex vitro of Phalaenopsis amabilis was influenced by many different spectra lights, considering that the various results of this influence from the genotype. It can be observed that the blue spectrum performed a great performance on cv. 6323 and on the Green spectrum cv. 6546.

This study is based on considerations regarding the teaching and learning of algebra in its introductory phase with seventh graders and eighth year of elementary school, having as final product an instructional sequence with the objective of introducing algebraic thinking more effectively. At first, there is a discussion of issues related to the introduction to the study of algebra, such as the difficulties and mistakes that students have upon the lights of the thoughts of various authors and researchers in Mathematics Education. It also provides general guidelines for teaching this subject according to official documents (Brazilian Curricular Parameters and Curricular Proposal of the State of São Paulo). Moreover, it contains a proposed instructional sequence that aims to introduce algebraic thinking effectively, bringing even discussions about the chosen methodologies. The second phase deals with the application of this sequence into two classes of eighth year of a public school from the state of São Paulo. Finally, we expose our impressions, the student outcomes and also suggestions in order to the sequence can be used and improved by other teachers.

The present study lies in the learning context where there is an alleged disinterest and difficulties of students when presenting the contents of arrays. From the contents above, the study aimed to describe the instructional sequence that aimed to provide an understanding of the Matrices content by students of 2nd year of secondary education, focusing on the use of technology as an ally in solving problems. In the first and second stage of the development of this instructional sequence it was detected through examples and exercises, that some students presented themselves unmotivated in face of difficulties regarding the resolution of problems involving content prerequisites matrices, such as handling of negative numbers in mathematical operations. From this preliminary assessment, attention was given to resume the content identified as deficient and concomitant and emphatically it was made use and application of educational software for teaching arrays. At the end of the five moments involving this instructional sequence, which occurred over twelve lessons, it was possible to arouse the curiosity of students and propitiate them to understand the content of matrices and hence promote greater involvement with the subject of Mathematics. Throughout the study presents considerations on the various difficulties encountered during the development of this work in order to teach the concept of matrix multiplication.

Fire is an environmental filter that selects species based on their traits and, in association with soil features are related to differences in plant species richness and composition. Functional diversity incorporates variation in species traits and allows one to evaluate the effects of biodiversity upon community functioning. It can be divided into components to elucidate response and effect links with environment. Both intra- and interspecific variation should be considered when analysing the role of environmental filters structuring communities. Sampling woody plants in a Brazilian cerrado reserve, we measured species richness, functional traits, abundance, environmental variables and litter decomposition rate. We calculate three functional diversity index. Then, we used model selection analyses to select the best model predicting functional diversity and richness based on soil variables in sites with three different fire frequencies. We calculated the community weighted mean of each trait and used an ordination to examine how traits changed across fire frequencies. We tested for effects of biodiversity upon ecological functioning. We also used an intra- and interspecific trait-based approach to test for shifts in each trait mean, reduction of trait range, and increase in niche differentiation. We found higher species richness and functional dispersion in more fertile sites where fire was frequent, and the opposite where fire was infrequent. However, soil influenced functional evenness and divergence only where fire was infrequent, with higher values where soils were poorer. We found low values of functional richness and high values of functional evenness and functional convergence. Functional components were related to environmental variables, indicating that functional diversity had response links with the environment: harsher environmental conditions lead to less phenotypic overlap and, consequently, less competition. Functional components did not predict litter decomposition rate. However, when environmental variables were also used, we found higher decomposition rate related to higher slope, richer soil, frequent fire, and higher functional richness. Therefore the effect links of functional diversity upon functioning were dependent on the cerrado environment. The inclusion of intraspecific variability did not increase the perception of environmental filters and competition to all traits. We found evidence for environmental filter to almost all traits analysed, except basal area and leaf toughness. Mean values shifted for five traits and ranges reduced for seven traits compared to null expectation. Also five traits presented niche differentiation indicating competition after the filter selection. Fire may change functional traits directly by hindering development of plants and indirectly by changing competition. Different fire frequencies lead to different plant-soil relationships, which may affect the functioning of tropical savanna communities. Both functional diversity components and functional identity of the communities are affected by fire frequency and soil conditions. Fire gradient changed the space traits by selecting similar species with more adequate traits.

The genus Trypoxylon consists of solitary wasps that build mud nests or nest in preexisting cavities, which brood cells positioned linearly are stored with paralyzed spiders. The male in species of the subgenus Trypargilum presents a singular behavior among Hymenoptera, playing the role of guard in active nests, which guarantees repeated copulations with the partner that interacts, especially before oviposition. It is expected that this behavior increases the chances of reproductive success of the guarding male. However, the constant presence of satellite males in nesting areas, associated to reports obtained in behavioral studies that pointed the receptivity of females assisted by a guarding male to extra-pair copulations, lay doubts in the effectiveness of reproductive tactics adopted by the guard. The aim of this study was to contribute to the knowledge of natural history of Trypoxylon (Trypargilum) species, through behavioral records, genetic analyzes of intranidal relatedness and analyzes of diversity and population structure. The nesting behavior of Trypoxylon agamemnon, Trypoxylon aurifrons and Trypoxylon nitidum in trap nests was recorded, mainly focusing on the interaction between the guarding male and the nesting female, beyond the role of the satellite male, who was constantly positioned near active nests. Genetic analysis of intranidal relatedness using species-specific microsatellite loci for Trypoxylon albitarse indicated that this species has a predominantly monogamous mating system, although extra-pair copulations have been detected. Since little is known about the population genetics of this group of wasps, we also present data from the genetic diversity and structure of five populations of T. albitarse, sampled in four states in Brazil, which indicated high levels of genetic diversity and significantly population structure.

This dissertation aims to analyze the pedagogical model used in a Bachelor of Agronomy offered to settled of the agrarian reform program, namely the alternation between school and community moments. The difficulty of the condensed subjects in the school time seems to be offset by the importance of the community time that provides local knowledge, through observation, analysis, and reflection, joining theory and practice, being pointed by the students as one of the reasons of higher learning. On community time, the greatest difficulties were balancing work with study and the lack of contact with the teachers. Moreover, the study ultimately allows the involvement of family, community and even the institutions for their development.

The genus Phyllanthus L. is the largest and most diverse of the family Phyllanthaceae with about 830 species that are spread mainly throughout the tropics, of which 200 are in the neotropics. From 100 species occurring in Brazil, where the genre is richest in South America, 40% of them occur in the southern region of the country, where is located one of the centers of diversity of the genus. The great diversity, richness and taxonomy still little studied, even regarding the circumscription of their species, justifying this study. Thus, the main aim of this study was to survey and analyze morphological and taxonomic aspects of the genus in southern Brazil, contributing to the knowledge of Phyllanthus in the country as well to the Brazilian biodiversity. This study includes an identification key, descriptions and comments on the taxonomy, geographical distribution and illustrations of the species. In southeastern Brazil were found 37 species of the genus: Phyllanthus acuminatus Vahl., P. acutifolius Poir ex Spreng., P amarus Schumach., P. angustissimus Müll.

Questions on how abstract symbols acquire meaning remain intriguing puzzles for behavioral and cognitive sciences. Recently, tow main approaches have been emphasized in the context of Behavior Analysis investigating these issues, the Stimulus Equivalence Paradigm and Relational Frame Theory. In this series of studies the main objective was to add data to discussion on this topic. In Study 1 it were investigated validity and accuracy of a Semantic Differential instrument which has been used to measure the transfer meanings equivalent stimuli. Factor analysis of the collected data provided indications of the validity of the instrument and the alpha coefficients obtained indicate that the two factors extracted in this analysis have acceptable levels of accuracy, although one of the factors must be revised. Study 2 described an experiment was conducted to evaluate the modification of meaning through reorganization of stimulus equivalence classes. Results showed the importance of delayed matching to sample in the transfer of functions to reorganized classes of equivalent stimuli. In Study 3, it was investigated the same phenomenon, the transfer functions, but in classes established primarily by reject control. The difficulty in establishing this type response pattern did not allowed clear inferences about the transfer with this specific type of control. Study 4 evaluated the transformation function using the IRAP. In the results we observed this phenomenon in both explicit and implicit measures. This set of studies allowed investigating different measures of transfer and transformation of functions, defined here as the study of meaning, and to observe important variables in this process especially the importance of establishing reliably relations between stimuli.
