The molybdates with scheelite-type tetragonal structure is a family of inorganic materials that has received considerable attention since the discovery of their luminescent properties, with emission in the visible spectral region. In this work, barium strontium molybdate crystals, (Ba1-xSrx)MoO4, with the compositions (x = 0, 0.25, 0.50, 0.75 and 1) were synthesized by co-precipitation method (drop by drop) in the presence of various solvents (water, 1,4-butanediol and diethylene glycol butyl ether) . The crystals obtained were structurally characterized by X-ray diffraction (XRD), Rietveld refinement, M- Raman spectroscopy (M- Raman) and Fourier transform infrared (FT -IR) spectroscopy. The shape and size of the crystals were observed by means of field emission scanning electron microscopy (FE -SEM). The optical properties were investigated by ultraviolet-visible (UV Vis) absorption spectroscopy and photoluminescence (PL) measurements. The XRD patterns, M- Raman and FT- IR spectra showed that all crystals are monophasic with a scheelite-type tetragonal structure, belonging to the space group I41/a. The lattice parameters and atomic positions obtained by Rietveld refinement were employed to molding [BaO8], [SrO8] and [MoO4] clusters into the tetragonal lattice. The microscopy images showed that (Ba1-xSrx)MoO4 crystals with different concentrations (x) and synthesized with different solvents showed changes in size (micro and nanocrystals) and the shape (octahedron, flowers, balls and rods) crystals. Photoluminescent emission at room temperature in different regions of maximum intensity was assigned to different densities of intermediate electron levels (deep and shallow) located within the band gap as a consequence of the degree of order-disorder structural in the crystal lattice and defects on the surface of crystals. Finally, we discussed possible mechanisms to explain the behavior photoluminescent.

Enzymes are potent catalysts, but operationally fragile, expensive and soluble. Industrial applications of enzymes, often, are possible only using immobilized enzyme. Nowadays, various studies have been performed aiming to immobilize enzymes onto magnetic carriers, which allow the selective recovery of the derivative by applying an external magnetic field even in complex reaction media containing other suspended solids. There are many studies using magnetic carriers in enzymes immobilization procedures, however there are no commercially available enzymes immobilized onto magnetic materials. In these studies usually are used carriers with not ideal characteristics for applications in industrial processes. The present study aimed to develop new magnetic carriers and methods for immobilization of enzymes in these carriers, penicillin G acylase (PGA) and cellulases have been used as model enzymes. The thesis was divided into five parts, in the first part (Chapter 1) the state-of-art is presented. The second part (Chapter 2) describes the synthesis of magnetic carriers robust, cheap and with good characteristics for applications in bioprocesses. For this purpose were tested the synthesis of silica magnetic microparticles (SMMps) in water-in-oil micro-emulsion using sodium silicate as silica source and superparamagnetic iron oxide nanoparticles as magnetic core. Materials with good magnetic properties, high surface area and mesoporous structure were obtained. SMMps structure was characterized, it was possible to control the final structure of the material according to the synthesis conditions. In the third part of this study (Chapter 3) was evaluated a new concept in enzymes immobilization using magnetic materials. Magnetic tags were co-aggregated with PGA and cross-linked with glutaraldehyde, producing magnetic cross-linked enzymes aggregates (M-CLEAs). Several reaction conditions were tested producing M-CLEAs with different characteristics and strong response to external magnetic fields. Derivatives with good recovered activity and increased thermal and methanol 50% (v/v) stabilities were obtained. M-CLEAs presented superior performance, in comparison with the free enzyme, in penicillin G hydrolysis experiments, being reused for three reaction cycles without loss of activity. In the fourth part of this study (Chapter 4) the immobilization of the Trichoderma reesei cellulolytic complex onto 17 carriers using 60 different immobilization conditions was evaluated. Covalent methods to cellulases immobilization resulted in total loss of the enzymatic activity. The immobilization by adsorption allowed preserving a portion of the enzymatic activity, however, the enzyme was desorbed from the carrier with the increase in the ionic strength. The best results were achieved for adsorption in MANAE-agarose followed by cross-linking with glutaraldehyde. Hydrolysis experiments using insoluble substrates showed that it is possible to hydrolyze such substrates even using immobilized enzyme onto porous carriers. The derivative was reused for ten reaction cycles (hydrolysis of filter paper) saving more than 90% of its activity. Finally, in Chapter 5, the T. reesei cellulolytic complex was immobilized by adsorption onto SMMp activated with amino groups followed by glutaraldehyde cross-linking achieving good results in terms of recovered activity.

This work describes for the first time an isocratic method in a single analytical run to quantify deacetyl iodixanol (iodixanol related compound C), iopentol (iodixanol related compound D) and cyclized iodixanol (iodixanol related compound E), as impurities in iodixanol. Iodixanol is a drug substance, dimeric, nonionic, water-soluble, used as a radiographic contrast medium, which is administered by intravascular injection. The impurities A and B were not evaluated in this work, since they are not commercially available as standards. The method was also validated for the quantitative assay, since there is no chromatographic method described in the current USP compendium for the assay. The impurities can be formed during the synthesis process of iodixanol, and it is important to quantify them due to their related toxicity. In this work, the reverse and hydrophilic interaction (HILIC) modes of elution were evaluated. The hydrophilic elution mode was selected due to good efficiency and selectivity. In both modes of elution, columns having the technology fused-core were used, since they demonstrate high efficiency due to their better mass transfer in comparison to conventional HPLC columns. The chromatographic separation was carried out on a kinetex® HILIC column (150 x 4.6 mm; 2.6 μm) at 20 °C using acetonitrile-formic acid (pH 3.2; 1.0 mmol L-1) (92:08, v/v) at a flow rate of 0.8 mL/min. The compounds were monitored at 243 nm and the total time of analysis was 45 min. The method was validated in accordance with the current ICH guidelines for determination of impurities which include selectivity, linearity, accuracy, precision, limits of quantification and detection and robustness. The limits of quantification (LOQ) were 0.479; 0.0606 and 0.133 μg/mL for the impurities C, D and E, respectively. Furthermore, the validated methods were tested in iodixanol samples. The test results of the analyses of impurities and assay in those samples are presented and discussed accordingly.

The focus of this work is Brazilians who migrated to the city of Toronto, Canada, through government programs to attract skilled labor from the Canadian government. This dissertation examines the relationship between skilled migration and social networks from fieldwork conducted in the city of Toronto between December 2011 and June 2012. Sought to understand how the migration process occurs, as potential migrants are actual migrants, from analyzing the decision to migrate and move to Toronto to adaptation processes in the destination society. From ethnography, participant observation and semistructured interviews with these Brazilian immigrants, we see how the internet and communications technologies are important mediators of this process, the creation of social networks and integration in existing networks. The profile of skilled labor bounded by the Canadian government was also analyzed in comparison to the profile of Brazilians who actually migrate, generating different modes of insertion in Canadian society. These paths and trajectories were analyzed from the theory of social networks and understood as adaptation strategies of immigrants. Different social groups and networks are formed in this process, including connecting individuals who intend to migrate, even in Brazil. Finally, gender differences were important in this process, they produced deferent types of networks and marked paths of women and men in the adaptation process in the city, having booked a chapter to this discussion.

This paper assesses the catalytic activities of LaCoO3 perovskite towards the steam reforming oxidative reaction of ethanol . Due to the low surface area which is commonly found on perovskite-type oxides , these were supported onAl2O3 , ZrO2 and ZrO2-Al2O3. The unsupported catalysts were prepared by precipitation and citrate methods whilst the supported catalysts were prepared by deposition -precipitation . The techniques employed to characterize the solids were: X -ray diffraction by the powder method (DRX) , X-Ray Fluorescence (FRX) Programmed Temperature Reduction with H2 (RTP-H2) Nitrogen Adsorption by B.E.T. method, X-ray Diffraction in situ, Raman spectroscopy, transmission electronic microscopy, scanning electronic microscopy, hydrogen desorption at programmed temperature TPD-H2 and Thermogravimetric Analysis. The preparation of the catalysts by precipitation and citrate routes proved to be efficient to obtain the perovskite type oxides .The supported catalysts showed surface area values larger than the unsupported ones, as there was the formation of other oxidase phases due to stand- perovskite or metal support interactions , as observed by the decreasing of reduction degree , through RTP analysis .The unsupported catalysts calcined at 700 , 800 and 900 ° C presented the best activity for oxidative reforming reaction than the supported ones. These, in turn, showed better catalytic activity towards the oxidative reforming reaction in relation to steam reforming of ethanol. By the X-ray Diffraction analysis in situ performed during the RTP-H2 and reaction tests, it was observed that the 20LaCoO3/Al2O3 catalyst prepared by method 2 - deposition -precipitation - showed lower size of crystallite of cobalt during the steam reforming reactions and oxidation in situ, therefore suggesting a better metal dispersion . The unsupported LaCoO3 catalyst prepared by precipitation method and calcined at 700ºC showed less coke formation towards the oxidative reaction of reforming of ethanol . Among the supported compounds the 20LaCoO3/ZrO2 showed the lowest coke formation in the same reaction. The analysis of scanning electron microscopy performed after the oxidative reaction, Raman spectroscopy the and Thermogravimetric Analysis, suggests that the unsupported LaCoO3 catalyst prepared by precipitation and calcined at 700ºC and the supported 20LaCoO3/ZrO2 catalyst showed lower carbon formation.

Issues related to sustainability have grown in importance for society, organizations, government and consumers and is one of the main changes that have been affecting the business environment. Companies seek to adapt themselves to meet internal and external pressures, hence, including sustainability represents more than an impact on the management of these organizations, for example in the performance measurement since new sustainability practices need to be followed and monitored. However this relationship between sustainability and performance measurement is little discussed in the literature. Thus, the aim of the research was to investigate how the adoption of sustainability practices acted as an inductor of change in performance measurement systems (PMS) of companies with sustainable practices. To this end two case studies were conducted in companies belonging to the Guia Exame de Sustentabilidade ranking, as these companies are recognized for already have sustainable practices in their operations. The research techniques used were semi-structured interview, consult to documents, and direct observation. Although the companies have different operating characteristics this diversity is not decisive in the changes observed in their PMS with the implementation of sustainability practices. It can be observed that in both companies there were impacts on the characteristics, the roles and processes of performance measurement systems. More specifically, changes can be observed in performance measures, the way of communication the results and information management.

This qualitative study of phenomenological basis, involves continuing education for teachers of Class Hospital. Aims to build, implement and evaluate, with the teacher 's Hospital Class, a proposal for continuing education to reframe the teaching practice in the educational space. Two teachers participated in a press conference audio-recorded with the core issues, which promoted the description of their practice in Hospital Class, signaling that knowledge could enhance the performance. The interview was transcribed and passed to the data analysis according to the methodology of phenomenological investigation. In a second stage of the research, we implemented a continuing education program for teachers Class Hospital. Monthly meetings were marked with two hours, in a Municipal Hospital in São Paulo. The meetings were described in a field notebook for further discussion of the data. Finally, by means of a written questionnaire, the teachers made the bid evaluation and the contribution of continuing education in pedagogical practice in Hospital Class. It can be considered that the interview was the initial prime importance to understand the knowledge and practices that teachers have in their Class Hospital pedagogical work at the hospital. Thus, it was possible to seek subsidies to build the proposed intervention, since the teachers themselves pointed out that it would be important to be worked on in-service training. The work of the researcher in organizing training meetings, within Class Hospital where they operate, from texts, videos and dynamic content which concerned the themes selected by the teachers can be considered a suitable design to think about ongoing education. At the end of the training process, it was revealed that the teachers were able to reframe the actions and pedagogical practices of the Hospital Class , reflecting on past experiences and imposing changes in teaching strategies and learning with students , patients and promoting actions with caregivers and staff health . Thus, it is relevant to note that the Continuing Education Program in service was built from the demands presented at each meeting by the teachers themselves and the application of the proposed training was also possible for the effort in giving them space, time and willingness to self-assess and then print new meanings to the practice teaching experience in Hospital Class. The teachers showed the importance of ongoing education as a space to reflect on practice and experiences and restructure work, advancing knowledge and enriching educational activities.

The UNS N26455 is a superalloy of the Ni-Cr-Mo system used on offshore platforms as components of injection pumps. This alloy has low-carbon content and high levels of Cr and Mo. This composition gives the material high resistance to various forms of corrosion in different types of environments. However, in some aggressive conditions containing high concentrations of chloride, high temperatures and presence of corrosive gases, the alloy UNS N26455 may show localized corrosion. As an aggravating factor, prolonged exposure of this alloy at high temperatures may favor the preferential precipitation of intermetallic phase P. This precipitate is rich in Cr and Mo and changes the composition of the alloy in the matrix/precipitate interface, and in turn promotes localized corrosion of the material. In this work, the effect of P phase precipitation in localized corrosion resistance was studied using electrochemical techniques: anodic potentiodynamic polarization, cyclic polarization, potentiostatic technique, crevice repassivation potential (THE), electrochemical impedance spectroscopy (EIS) and Mott-Schottky (MS). The experiments were carried out in environments containing high concentrations of chloride ions (100.000 e 180.000 ppm), with and without CO2 saturation, and at temperatures of 25 °C, 40 °C and 75 °C. The potentiodynamic results indicated that the alloy UNS N26455 in as-cast condition is extremely resistant to pitting corrosion. On the other hand, increasing the concentration of precipitates in the microstructure of the alloy, active dissolution occurs in potentials above 250 mVAg/AgCl. After potentiostatic testing and analysis by SEM, it was found that the dissolution occurs at the interface matrix/precipitate. The repassivation potential is not affected by the concentration of P phase, however, the weight loss obtained in the crevice corrosion test increased with the addition of the second phase in the microstructure of the alloy. The EIS results showed that the polarization resistance decreases with increasing P precipitates, indicating changes in the characteristics of the passive viii film. MS experiments showed that the passive film formed on alloy UNS N26455 shows n-type semiconducting behavior and the donor density increases with increasing concentration of the second phase.

The concept of metacommunities incorporates the influence of local and regional factors in structuring communities and has supported recent approaches related to patterns of distribution, abundance and species interactions. Within this concept, the species sorting model that assumes that a community is governed only by local factors, while the mass effect model assumes that a community is governed by local and regional effects. A stream system has a hierarchical dendritic network, in which the upstream water bodies are smaller and tend to increase in the downstream direction due to the connection with other streams. To stream fish, the dispersion process by the channel reveals the importance of regional factors on the structure of metacommunities, while habitat heterogeneity acts locally, and may reveal boundaries between metacommunities. This study aims to determine whether there is the formation of metacommunities along the longitudinal gradient and models which explain this structure. We captured fish populations and raise environmental information in three streams (15 reaches of 70 m) of a small watershed of the Atlantic. A principal component analysis (PCA) was applied to describe the environmental gradient and to verify the occurrence of this metacommunities apply a gradient elements of metacommunities analysis (EMS). The pattern of distance decay relationships (DDR) was used to verify whether metacommunities are influenced by the effects of local and / or regional and so seek explanations for the pattern found. We can say that there are two distinct communities (clementsian pattern of metacommunities), one nearest the mouth with no defined pattern caused by a process mass effect and a more flush with standard board from a species sorting process. Distinguish these communities is of great interest to conservation purposes and the development of strategies for biomonitoring. For example, for communities downstream, where the environmental changes caused by urbanization are more prevalent and there is the possibility of removing this source of environmental impact, ensure connectivity of streams is a good strategy since the species moving more intensely and are very dependent on the source of colonization. On the other hand, communities further upstream, even if there is a disconnect with the region downstream promoted by the damming of streams for water harvesting, these communities will remain theoretically provided that local conditions are guaranteed, ie, there is a pressing conservation environmental integrity of these excerpts.

Code generators play a key role in model-driven software development. They are responsible for transforming high-level assets (models) into implementation assets (code). Most generators are based on templates, which are pieces of text instrumented with code expansion elements. They receive an input and produce an output according to the template's programming. To build such template-based generators, the code of an existing implementation, already tested and validated, can be used as a reference, in a process known as code migration. With software evolution and the need for changes in the code generator, the templates start to differ from this reference implementation. In order to restablish the synchronization, additional effort is required. Tackling the challenge of keeping these assets synchronized (reference implementation and templates) is this dissertation's subject. The goal is to provide some automation to the code migration process, even if partial, in order to increase productivity in the maintenance of code generators. A mechanism was developed to make it possible to automatically reproduce changes that are performed in the reference implementation into one or more code generation templates. This mechanism was evaluated through an empirical study, yielding good performance in a controlled environment. This indicates that automation can help to reduce the effort in the maintenance of code generators in a model-driven development context.

Multimodal interfaces are becoming popular and trying to enhance user experience through the use of natural forms of interaction. Among these forms we have speech and gestures inputs. Speech recognition is already a common feature in our daily basis but gesture recognition has just now being widely used as a new form of interaction. The Brazilian Sign Language (Libras) was recently recognized as a legal way of communication since the Brazilian Government enacted the law N˚10.436 on 04/24/2002, and also has recently became an obligatory subject in teachers education and an elective subject in undergraduate courses through the enactment N˚5.626 on 12/22/2005. In this context, this dissertation presents a study of all the steps that are necessary to achieve a complete system to recognize Static and Dynamic gestures of Libras, being these steps: Segmentation; Modeling and Interpretation; and Classification. Results and proposed solutions will be presented for each one of these steps, and the system will be evaluated in the task of real-time recognition of static and dyamic gestures within a finite set of Libras gestures. All the solutions presented in this dissertation were embedded in the software GestureUI, in which the main goal is to simplify the research in the field of gesture recognition allowing the communication with multimodal interfaces through a TCP/IP protocol.

Contemporary society faces problems arising from impacts to the environment, causing damage to the countryside, agricultural production and family farming. This study aimed to know the relationship of man field with his work environment, evaluating management practices used by him to guarantee a living for his family and their financial stability. It were interviewed school-age young adults and milk producers of thirteen family farms located around the Mantiqueira Ecological Corridor under influence of Ibitipoca State Park. . The physical and socioeconomic characteristics of the study area was based on relief, vegetation, climate, use and land cover, the local economy, the relationship between the community and the Ibitipoca State Park, and communities profile. It was used a qualitative-quantitative methodology named Discourse of Collective Subject (DCS),, with tabulation and organization of interviews by means of the Qualiquantisoft® Software. Based on the PSR (Pressure-State- Response) model, indicators were proposed that generated pressure indexes on the producer s decision making (IP), for the application state of management practices (IE) and for the response of the environment to the producer s management (IR). The property sustainability index (ISP) was calculated from the arithmetic mean between IP, IE and IR, and indicated the evolutionary trend for these properties.The results indicate that the study area has a history of environmental, social and economic pressure. Despite the intense scrutiny and understanding of the need environmental conservation, a variety of environmentally inadequate management practices are used in order to supply family demands and maintainining the family income. Farmers and school-age young adults consider the environment an obstacle to production and stay in the field. We conclude that, despite the historical tradition of agriculture in the studied area, the way in which dairy cattle activity has been developed can compromise environmental integrity and therefore the life quality and the local population income.

Inclusive education is a disturbing and challenging issue for its difficulties and limitations. Throughout history, this subject has constituted controversial. However, in recent years that legal achievements are being achieved, leading to a new social positioning, especially in regards to education. However, the fact that there are standards supporting the right to education for all, including those with disabilities, it doesn't mean that such guarantee is being observed for real, which is why effective oversight is needed by society and institutions. One of the existing institutions that have empowered by the constitution to oversee and enforce legal requirements that protect the interests of society is the prosecutor, through establishment of administrative procedures. Thus, the present study aimed to search, identify and analyze the proceedings instituted in the prosecution in the state of São Paulo, involving the theme of rights to educational inclusion of people with disabilities in regular schools, in the period between 12/01/2009 to 12/01/2011, based on the previous work discussing the role this institution and defending the right to education . Having in mind the purpose of the research, we used a qualitative approach to document analysis some court procedures. The results point the prosecutor as an important ally in the legal achievements of people with disabilities related to educational inclusion and brought the discussion of the importance of public awareness of people with disabilities to advance their rights.

This study was part of a Doctoral Course research, of the Post Graduate Program in Education, by the Federal University of São Carlos, and was developed at the Brazilian Air Force Academy (AFA) in the city of Pirassununga / SP. The research aimed to map the specificities of the military instructors teaching and learning process, regarding to the theoretical and practical concepts about the teaching, and the teaching and learning process of cadets at the Air Force Academy. Therefore, the research subjects were three military airmen instructors,graduatedby AFA, who taught classes in the AFA´s Division of Education; were also subjects of this study 78 cadets of the Aviation Course who, in 2012, were in the last year of the mentioned Course. The theoretical referenceof the work was composed by Libâneo studies (1994), regarding to traditional and technicistpedagogical trends, the role of teacher and student and the characteristics of the educational process in these conceptions. Mizukami (1986, 2002, 2004, 2005-2006) contributes towards to traditional, constructivist and technicistteaching, and discuss about the initial and continuing education, as well as details the processes of teaching and learning. About the construction of teacher identity, the contribution comes with Veiga (2010, 2011), Gatti (2011), Pimentaand Anastasiou (2011). The authors, as well as Gil (2009) refer to higher education, about giving classes, about being a teacher. Still, Zabala (1998) addresses the interaction in the classroom as fundamental for the growth of the students, also bringing consistent arguments about the conception of constructivist education. The teachingactivity as a work, the teacher´s knowledge and the professional development have theoretical basement in Tardif (2002, 2009). Processes of teaching at university, coined by Anastasiou and Alves (2003), is developed in this study. Finally, Shulman (1986, 2004, 2005) collaborates with its work on the knowledge base for teaching, pedagogical reasoning and also considers the reflective processes on that path. However, about thethinking aboutteaching practice, the ideas of Schön (1995, 2000) and Pérez Gómez (1995) are discussed. The methodology used in this study was a descriptiveanalytic one, based on data collected from open non-structured interviews, open semistructured interviews and questionnaires applied to the subjects. From the data analysis it was possible to comprehend that the military instructors have a very consistent specific training in their area, Aviation,while they don´t have preparation for teaching in military higher education and learn to be a teacher in pedagogical practice in the classroom . The responses of cadets confirmed this situation, and also demonstrated that their conceptions about the teaching, learning, the importance of interaction in the classroom, the didactics, the best and the worst teacher, are very close to the concepts of the military instructors. Therefore, the processes of teaching and learning are constructions that occur throughout the school experience, at any of the levels that the subject is inserted. In short, it demands work, knowledge and commitment by the teacher; and activity, study, dedication and interest by the student.

The aim of this work was to synthesize and characterize bilayered films of polypirrole and poly(2,5- dimercapto-1,3,4-thiadiazole) poly(DMcT) as possible materials for supercapacitor electrodes. Composites of carbon fiber (CF) and polypirrole (Ppy) were prepared at 0.8 V vs. SCE up to charges of 1, 2, 5 and 10 C in order to verify the experimental conditions to obtain films presenting the best morphological and electrochemical properties, as well as to optimize a methodology to obtain the composite CF/poly(DMcT)/Ppy. Morphological analyses indicated that Ppy is globular and grows homogeneously all over the CF surface, and electrochemical tests of the composites CF/Ppy led to the highest specific capacity for the thinnest (1 C) film. The presence of both polymeric films was confirmed by IR and Raman spectroscopies, and their distribution on the carbon fiber was checked by elemental analyses using Energy Dispersive X-Ray spectroscopy (EDS). Galvanostatic charge-discharge tests on a two-electrode cell having the same composite as cathode and anode (Type 1 supercapacitor) indicated a fair initial capacitance value of 200 F g-1 for the CF/Ppy (1 C) composite, but presenting low electrochemical stability (capacity loss of 72% after 1000 cycles). When narrower intervals for the cell voltage (0 to 0.5 V, 0 to 1 V and 0 to 2 V) were employed, both composites CF/Ppy and CF/poly(DMcT)/Ppy presented high electrochemical stability during 5000 cycles. Finally, spectroscopic studies indicated the reduced, polaronic and bipolaronic forms of Ppy, and possible interactions between the Ppy and poly(DMcT) molecules.

Over the recent years, the incidence of human fungal infections has shown a significant increase. Aspergillus fumigatus is a filamentous fungus opportunistic pathogen responsible for many human respiratory diseases, including invasive pulmonary aspergillosis, which is the most serious form of infection . Studies show that A. fumigatus virulence has a multifactorial process associated with its structure, capacity for growth, adaptation to stress conditions, evasion mechanisms of the immune system and ability to cause harm to the host. CWI (via cell wall integrity ) is a signaling cascade activated in yeast cells under conditions of cell wall stress and plays a role in the adaptation of various fungal pathogens in the human host . In many fungi , CWI is triggered by activation of protein kinase C ( PKC ) and that this pathway is associated with the transcription of genes related to maintaining the integrity of the cell wall and its redevelopment. In this work, a mutant Gly579Arg (G579R) was constructed by transformation mediated by inserting a gene replacement cassette comprising a G2044C transversion located in the cysteine-rich domain controller C1B pkcA of A. fumigatus. From the phenotypic analysis of the mutant strain was observed in the involvement of pkcAG579R CWI since the mutant showed high sensitivity to agents such as CR (congo red) and CFW (calcofluor white) . Furthermore, pkcA is also involved in tolerance to oxidative stress caused by paraquat and menadione. Additionally it was found to increase the sensitivity of the mutant pkcAG579R temperature variations as well as the inhibitor of Hsp90 radicicol. Como CWI is related to the transcriptional activation of biosynthetic genes and rugged cell wall (such as glucan synthase, glucanosil chitin synthases and transferases) the abundance of major genes coding for these enzymes was analyzed by RT-PCR in real time. Based on the tests can be α -1 ,3 glucan synthase ( agsA-C ) dependent signaling mediated PkcA for correct expression. Furthermore, genes such as β-1,3 glucan synthase (fksA) glucanosyltransferase (gelA-C) and some chitin synthases (chsB-E-C) appear not to be dependent function and CWI PkcA . These data demonstrated the role of pkcA signaling cascade in the maintenance of cell wall and thermotolerance in A. fumigatus. This work was the first in which a systematic analysis of gene pkcA was conducted in the human opportunistic fungal pathogen A. fumigatus.

The Caravana do Cordel and the building of a northeast in movement in São Paulo is a research about the way the stories are mobilized, the actions and representations of the Northeast of Brazil in the speeches of Northeastern migrants settled in São Paulo, belonging to the Caravana do Cordel . I investigate the reinterpretation that is built by those subjects who maintain a strong mnemonic relationship with the Northeast of Brazil, with the lived experiences in this geographical space, social and symbolic, both in the past and present. I assume that although these poets crystallize a certain image of the Northeast of Brazil where they were born, they also create other northeastern", through a discursive dynamic construction.

The municipality of Altinópolis is historically recognized by coffee farms and tourist attractions, and currently local agriculture has diversified and is under agribusiness pressure. To analyze and compare the sustainability indexes of production systems in the municipality of Altinópolis, according to the size of the farms, were established social, economic and environmental indicators. These indicators were measured by applying semi-structured interviews in the production units. After analysis and discussion of the data collected, the sustainability indices were determined and represented by biogram. It was observed that family farms have higher levels of sustainability. Positive highlights of family systems are: diversity of commercial crops, adoption of soil conservation practices, interactions of agricultural activities, rural family background and family work. In contrast, medium to large production systems (> 4 fiscal modules) achieved positive highlights of: receiving frequent technical guidance, conducts periodic correction of the soil, have good infrastructure (machinery, implements and improvements), and create salaried jobs in the batch.

The movements and regulatory reforms, especially in the 1990, brought significant changes to the organization and management consequences as the public school, which arise from conceptions or practices of evaluating a given context. Knowledge of assessment methodologies of the school, or the Institutional Self Assessment, can stimulate the management team to work more collectively, participation valuing each and portraying the school as it is, from the point of view of their community. The Municipal School Professor Ali Homsi Salles Cunha in Sao Jose do Rio Preto − SP, created, recreated and effected in the period 1999-2010, a model of institutional selfevaluation itself through questionnaires processed in evaluation reports. In this dissertation, we used the cutout from 2006 to 2009 due to the significant changes that have occurred in this period and that have led to specific changes in the organizational culture of the school. We attempted to place a framework of theoretical and conceptual reference concerning the evaluation and Institutional Self-Evaluation in education and school; define the methodological procedures as presented searched the school and report the construction process of self-evaluation, showing it through analysis of documents, reports and other evaluative Institutional (Political Pedagogical Project, School Plan etc.). To this end, we prepared two broad categories of analysis: social and educational policies and organizational culture and management dimensions. From these categories, we created others with timely information for this investigation. Analyzed as before and after school was to establish annually the Evaluative Report and found that the changes in its organizational culture to have a democratic management. The methodology used was to work with questionnaire responses from parents/family segment and the evaluative reports collectively built the cutout of four years (2006- 2009). It was concluded that the self-assessments, developed, implemented and analyzed collectively by the institution, become facilitators tools to streamline diagnostics and troubleshooting, taking into account participation in the establishment of a democratic management process.
