This research seeks understanding how different transvestite's generations that prostitutes themselves in the countryside of São Paulo built their bodies and subjectivities. I seek to understand the existence of the pressure between this identity project and the creation of two categories, the older and younger, observing the detachment and existent approximation between different generation of transvestites, just like specific valuations of some bodies and behaviors from each one of them. The study realized in Sao Carlos and Ribeirao Preto undertook ethnography at the prostitution areas and the transvestites homes, combined with online contacts through social media like Facebook©. Based on Queer theory, the Brazilian studies about the travestite‟s and the the idea of "generationality" and aging, I seek the creation of particular idea of being young and aging as travestite for the ones that prostitute themselves. Seeing that for this group aging is not only related with the age but with a specific relationship with the body, the job market and the social relationships that develops and keep the environment where they live.

This research aimed to understand the discourses about the Ronda Ostensivas Tobias de Aguiar (ROTA), focusing on the speech of Police officers and politicians over control the "organized crime." Therefore, we analyzed two recent episodes of "Confrontation" between Police and incriminated subjects (Itatiba - SP in May 2011 and Várzea Paulista - SP, in September 2012) that ended with large numbers of "Suspects" killed. We took this two emblematic cases as a way to cut temporally two distinct periods, before the so-called " public security crisis " apparent normality, and the other period in which the socalled" crisis "occurred, producing increase homicide rate in São Paulo. Documents were analyzed as case of studies, master's workes and professional thesis produced by officers in Polícia Militar do Estado de São Paulo (PMESP), News, newspapers, press officer of the Secretary of Public Security and speaking managers of Public Security. As a significant result, we found that since 2009, the State of São Paulo, there was a direction of PMESP activities in "combat organized crime "that had the support of other sectors of the justice system and state administration, such as the Public Ministry and Secretary of Administration prison that provided information to ROTA, looking for integrated approach against "PCC". The integration between agencies was maintained in relative secrety, while procedures adopted in the "fight agains to organized crime" remained opaque by the whole process, reflecting praticies of a militarized strategy favoring lethality and use of force as means of crime control, and instead of controlling the "violence", he turned out to produce it, especially in the year 2012.

This study aims at analyzing the constraints in the work of the professor-researcher in regard with the innovation policies. The hypothesis is that the current innovation policies progressively link the work of the professor-researcher to the business sector. In order to analyze the hypothesis, the political and institutional relations of the University of São Paulo were studied, more precisely in the campus of Ribeirão Preto, as well as their articulations with public-private sectors and partnerships. Documentary analyses and data collection on innovations, applied researches, incubator companies and productions and service rendering interpreted by the area of Science and Technology were held, as well as four semistructured interviews with innovation agents. It was found that the University of São Paulo constituted its own institutional arrangements by means of articulations with institutions specifically in the municipality of Ribeirão Preto. Furthermore, institutions of the university are relevant in this process, such as USP Agency of Innovation. However, it was found that Fundação Instituto Polo Avançado da Saúde de Ribeirão Preto (FIPASE), a municipal foundation which supports innovation, encourages specific political and institutional devices for the incentive and development of researches applied to the demands of the business sector, in order to induce the researchers in the university to carry out certain practices of innovation. Consequently, it also induces part of the graduation research of the campus to turn into applied research centers, enabling the creation of spin-off companies. It is pointed out that these institutional arrangements for the development of the applied research, however, would not be possible without relevant changes in the professorresearchers‘ working hours, undertaken by them, based on decisions in the university which result in regulations and resolutions that make flexible and encourage the relation university-company. It can be concluded that, in spite of the narrowing of the link between the work of the professor-researcher in the Science and Technology area and the business sector, the innovation policy in the campus of Ribeirão Preto meets the interests of the academic community much more than the ones of the business sector itself, and that, in this process, contradictorily, it is the university that reconfigures itself to the patterns of the logic of the businesses, typical of the companies, rather than the companies that modify themselves or develop the practice of research and production of the technological knowledge, typical of the university and the scientific area.

Code inspection is an important activity to assure the software quality that, in some cases, shows a better performance than the testing activity. Its application depends on the use of reading techniques that assist the inspector both in understanding the code and in executing the inspection. Although there are some reading techniques that support code inspection, Stepwise Abstraction, for example, was set to the procedural paradigm and requires that even the simplest code be abstracted. Other techniques such as Checklist, Use Case based, etc., are prone to the inspector’s experience since they do not provide a systematic procedure and they are not supported by facilitating resources. A computer-aided code inspection providing visualization facilities for applying Stepwise Abstraction – the CRISTA tool - was developed in another work of this research group. This tool has shown to be an effective and efficient approach for code inspection. Objective: To present the reading technique KIRT (Key-Information Reading Techniques) that was defined through operational scenarios, in order to establish systematic guidelines for conducting the code inspection. KIRT was based on reading patterns obtained from the analysis of the inspectors’ behaviors, considering features of the object-oriented paradigm, and using visual metaphors that guide the inspector during the inspection. Method: Considering the intention of understanding how the code inspection is carried out in practice, the research was based evolutive cycles, performed through four cycles that were the basis for defining and evaluating KIRT. In each cycle, studies were performed to generate subsidies for supporting subsequent cycles. The KIRT technique was set with the main purpose of identifying defects and, in addition, source code improvements. Once defined, three experimental studies were conducted to: (i) evaluate the contribution of the visual metaphor implemented in CRISTA tool for defects identification; (ii) evaluate KIRT technique (using two different metrics) regarding the effectiveness and efficiency in the identification of defects and source code improvements; (iii) evaluate KIRT technique in relation to the Checklist technique. Results: The results of the experimental studies showed that (i) the visual metaphor influenced the number of source code improvements and false positives identified; (ii) KIRT technique (instantiated by two distinct metrics) was complementary; (iii) the effectiveness and efficiency of the KIRT technique were better than Checklist. Conclusion: In the experimental studies the KIRT technique showed satisfactory results regarding the effectiveness and efficiency in identifying defects, and generated few false positives. Moreover, the KIRT technique identified more source code improvements than Checklist. Based on the results we can say that KIRT technique can be used for code inspection in practice, mainly because they are supported by CRISTA, which provides procedures and visual metaphors for conducting the code inspection activity. Consequently, if they reach the objective of identifying defects, we can say that they contribute to the overall quality of the software.

The remarkable advances in scientific research of materials for ever demanding service requirements has led to novel developments of biomaterials, especially in the field of surgical implants. In this field, the semi-crystalline thermoplastic PEEK (poly-ether-ether-ketone) has been selected as one of the most suitable for orthopaedic applications. Due to its excellent short and long term mechanical properties and also associated to its elastic modulus compatibility with that of the human bone, the polymer safely fulfills the mechanical and biological requirements for injection moulded implants with complex design. However, as also verified with metallic implants, the PEEK osteointegration is slow and, therefore, can be enhanced with bioactive ceramics coatings of hydroxyapatite (HA), obtained mostly using plasma spray technique. However, as the high temperatures related to the plasma process can impair significantly its mechanical performance, this study aims to investigate the influence of the plasma spray process on the mechanical fatigue behaviour of injection moulded PEEK coated with HA. Using mechanical test specimens with three distinct treatments: (i) PEEK as molded, (ii) PEEK with thermal plasma shock and (iii) HA plasma coated PEEK, several characterization techniques, which include X-ray diffraction, differential scanning calorimetry (DSC), short-term tensile and flexural tests, dynamic-mechanical thermal analysis (DMTA) and deformation-controlled flexural fatigue tests were performed. The quality of HA coating was considered adequate, as identified by X-ray and SEM analysis. The experimental data on the main mechanical characterization of HA coated PEEK, demonstrated that the plasma treatment contributes to a significant increase in the short-term flexural elastic modulus and strength properties and also reduces the stress relaxation rate (residual stress) during the fatigue cycling up to one million cycles. These increases in the flexural stiffness and residual fatigue stress of PEEK are induced by a increase in the polymer crystallinity content and the presence of additional thermal residual surface stresses on the PEEK surface exposed to the plasma thermal shock, as identified by DSC and DMTA analysis.

This research is part of the institutional evaluation field, in particular, the evaluation of undergraduate courses, aiming the development of a methodology for analyzing the results of the evaluation process as a way to subsidize on a broad perspective the decision-making, and more specifically, the reformulation processes. The proposed methodology seeks to integrate information from different evaluation processes related to undergraduate programs, with emphasis on those established by the Sistema Nacional de Avaliação da Educação Superior (National Higher Education Evaluation System, SINAES) to analyze them critically. In this case, the report of the institutional self-assessment, the report of the Commissions assessment in loco of the Instituto Nacional de Estudos e Pesquisas Educacionais “Anísio Teixeira” (National Institute of Educational Studies and Research “Anísio Teixeira”, INEP), coming from the regulatory processes of recognition and renewal of recognition of undergraduate courses and the course report of the Exame Nacional de Desempenho de Estudantes (National Examination of Student Performance Report, ENADE). In addition to these, it will be exemplified other internal and /or external indicators that may be included when they’re relevant to the course. The objective is to stimulate analysis of the results of evaluation processes which underwent certain undergraduate courses, organizing information and making it accessible to those involved with the course, especially the academic bodies responsible for formulating a critical and systemic diagnosis on the implementation of the Educational Project Course and, when appropriate, for proposing modifications. The theoretical framework proposed for this analysis is based on the concept of emancipatory evaluation, whose basic principle is the pursuit of transformation of a given reality from a participatory assessment process. The preparation of the methodological proposal was preceded by bibliographical and documentary research that theoretically grounded it and then was developed experimentally in an undergraduate degree at UFSCar. The methodology we used for the development of the proposal was the action-research, and in order to validate it, it was held the meeting of the focus group with the teachers of the course. The central idea of the proposal is to collect, organize and analyze the indicators resulting from internal and external evaluation processes of undergraduate courses, organizing the information into large dimensions for a critical comparison of results from different sources. In this paper, a pilot spreadsheet was developed in twelve dimensions that organizes the extracted results from different sources of information, thus contributing with a comparative analysis and critique of each dimension evaluated. The results showed that this methodological approach proved to be appropriate to support the analysis performed by teachers on the results of evaluations to which the course has been submitted. The authors emphasize the importance of the multiple evaluation processes for the construction of a broad diagnosis of the current situation; More than that, it was found that the process of analyzing the information organized as proposed favors collective discussion on the Pedagogical Project of the Course and encourages educational evaluation culture in its formative and emancipatory sense; It showed up, too, the importance of an education expert who has knowledge of the methodological approach and on the evaluation processes.

The Statistical Process Control (SPC) is recognized in the literature as one of the main tools for controlling and improving the quality and productivity. The control chart is a central element of the SPC; and these, statistical tools whose efficiency depends on certain skills and organizational behavior. With regard to the results to the organization, it is observed that the use of control charts can be divided into two groups: those that can be directly attributed to reduced variability called hard; and those associated with the motivational aspects, or organic, called Soft. Despite the arguments in favor of SPC survey, a study conducted in the automotive sector shows that about 70% of companies have some difficulty in conducting their activities related to the SPC. On this, the literature indicates that factors related to methodological, statistical and managerial aspects of control charts of the implementation process are conditions for the success of a structured plan of implementation of the SPC. Given this situation, it is objective of this thesis contribute to an effective use of control charts by national companies, and to advances in research. To this end, we opted for a field survey to capture and describe the perceptions of experts who use control charts and working in the automotive industry. The field research was structured in three basic dimensions - statistics, methodology and management, and the results achieved by the use of the SPC, divided into Soft and Hard. The method used was based on a survey, which has a population of interest was the managers of SPC programs that use the control charts for more than 01 years in the auto parts industry. This survey was sent to 98 individuals in the population of interest, identified in the Official Guide Auto parts Industry (2014), which resulted in 37 questionnaires and valid for analysis. The results of this field research validated the hypotheses in part the theoretical framework, but showed, besides the complexity and importance of methodological and managerial aspects in the implementation of the SPC, there is a significant gap between theory and practice. This may partly be explained by the dissonance between the main scientific advances in the field, especially in the statistical aspects, and the controversies about the real benefits of SPC program. As a result of this thesis is recommended that field research has been done for that to report real success stories of the SPC; whose cases are examined in depth so that good practice is disseminated in the academic environment.

This research aims to outline and scrutinize the set of musical practices and repertoires widespread among the Macushi, an indigenous population of Karib linguistic affiliation who currently inhabit the fields and valleys of the basins of Branco and Rupununi rivers, a region that is politically divided between Brazil and Guiana. This investigation is temporally restricted to the last decade – between 2005-2015 –, and geographically restricted to the population situated on the Brazilian side, more specifically on the territory currently known as Raposa Serra do Sol. This study intended to detail the practices, significations and meanings attributed to different musical rhythms and repertoires of Makuxi in order to understand what kind of motivational factors were implicated in the the spread of forró rhythms and in the reworking of traditional musical rhythms, notably the parixara and the tukui, in a political context in which such musical repertoires were reinterpreted and used as "cultural performances".

The sugarcane has great economic importance in Brazil. To keep productivity several biotic and abiotic factors can positively or negatively influence. Among them, weeds, nematodes and synergistic action between pesticides to control both can be cited. Thus, the present work aimed at studying possible common weeds in the mechanized harvesting system that can serve as hosts for the root knot nematode: Meloidogyne incognita and / or M. javanica and study the interaction between herbicides and nematicides used in the groove planting of sugarcane. Two experiments were carried in a greenhouse at the Agricultural Sciences Center (CCA-UFSCar), Araras, SP. The first experiment evaluated the host status ten weeds, as follows: Ipomoea triloba (Dammer), Merremia aegyptia (L.) Urban, Luffa aegyptiaca Mill, Euphorbia heterophylla L., Ricinus communis L., Crotalaria spectabilis Roth, Mucuna aterrima ( Piper & Tracy) Holland, Chloris polydactyla (L.) Sw., Digitaria horizontalis Willd., Urochloa decumbens (Stapf) RD Webster and the control (tomato Santa Cruz Kada) when inoculated with M. incognita or M. javanica in a completely randomized design in a factorial 11 x 2, with six repetitions. The plants were inoculated with 2.000 eggs and J2, and there were three plants per plot (6.000 eggs and J2 per pot - repetition). Sixty days after inoculation (DAI) the plants were removed and evaluated according to the reproduction factor (FR), final nematodes population (PF) and reproduction index (IR). In the second experiment the effect of interaction between two nematicides applied in contact with the stalks was evaluated. The nematicides tested were: benfuracarb (5,0 L ha-1) and carbofuran (50 Kg ha-1), and the herbicides applied preemergence of culture were: sulfentrazone (1,6 L p.c. ha-1), diuron + hexazinone (2,5 Kg ha1), saflufenacil (0,14 Kg p.c. ha-1) and amicarbazone (1,5 Kg p.c. ha-1). The experiment was carried in a completely randomized design in a factorial 15 x 5, with four replications in three sugarcane varieties (RB867515, RB975952 and RB975201). The first factor was corresponded to the 15 treatments and the second, to the five evaluation periods. Evaluations of intoxication symptoms were performed at 7, 15, 30, 45 and 60 days after emergence (DAE) of culture. In the last assessment biometric parameters height (cm), leaf area (cm²) and dry biomass of the aerial part (g) were evaluated. Regarding to the host status of weeds, it was found that L. aegyptiaca behaved as host of both nematodes, with FR > 1, higher than the control. The D. horizontalis was classified as host of M. incognita and non-host of M. javanica. C. spectabilis had the lowest FR and PF. R. communis and I. triloba present galls when inoculated with M. incognita, but were not considered host for presenting FR < 1. None of the weeds tested was considered immune, that is, with RF = 0. Regarding the interaction of herbicides and nematicides in all treatments, plants recover 60 DAE, and in treatments with the use of sulfentrazone increase in symptoms of poisoning was observed. As for the biometric parameters evaluated at 60 DAE, there was no statistical difference only in the variety RB867515 for height. In this case, the treatments amicarbazone / benfuracarb and amicarbazone / carbofuran plants were higher than the control and other interactions.

In 2001, Larissa Mies Bombardi performed a case study regarding the Agrarian Inspection Law, and more specifically the Capivari agrarian core, founed in the 1960s and that became a rural neighborhood. The present paperwork seeks a reviewing of this case study in order to approach the economic and cultural changes expressed through spacial transformations that took place between 2001 through 2015. The goal consisted in understanding the farming production processes in this core and the trasnformations ocurred since Bombardi's study, upon the concept of reproducting peasantry, of the peasants as a reproducting unit. For the conceiving of this work, first and foremost, a study of Larissa Bombardi's “O Bairro Reforma Agrária e o processo de territorialização camponesa” took place, hence the book was taken as primary reference. After, there was the accomplishment of field research, with numerous interviews held with different profiles of local dwellers. Beyond that, the discussion regarding the changes and transformations that took place since Bombardi's study and the neighborhood and the peasantry's current situation, as of 2015. After that, there's a reflection concerning education in rural schools with a singular perspective that englobes the peasant reality. Thus, it's concluded that the peasantry's deal shows it's modifications and adaptations as they happened through the years, given the numerous difficulties regarding their reproduction, as well as “mechanisms” adopted for survival and continuity of this class as expressed by the different dweller profiles compiled in this paperwork. Furthermore, it's concluded that such cultural and social modifications impact directly in the neighborhood's configuration.

This study presents an analysis of the diversity of forms on organic food production commercialization in Vitoria (ES), and the discussion about this research theme. The goal is to understand how and under which conditions the market valorizes the local production, strengthening the ecological family production and the food sovereignty. The research methodology took into consideration quantitative and qualitative data, utilizing available public information and data acquired in field research. The evaluation shows that organic products are commercialized by direct sales, in organic outdoor markets and fair markets, and by indirect sales in supermarkets, specialized stores and restaurants. Among the evaluated commercialization channels, were the organic product outdoor markets that showed a greater product diversity, in addition to a better price, which were up to five times lower than in the supermarkets. Furthermore, organic product prices, when compared to the equivalent conventional ones, always showed higher values in indirect sales. However, among conventional and organic street markets, organic products prices were higher, equal or smaller than their conventional equivalents. Therefore, it concludes that this commercialization channel valorizes the organic family production, promoting the empowerment of family producers and the access to healthful alimentation for local consumers.

Violence is a current topic, and violence perpetrated by intimate partners is growing concern of social, legal, and health policy. The subject is already configured a public health problem, considering the physical and emotional harm caused to the victim, and study data refer to women victims of domestic violence seeking up to six times more for the health service. Pregnancy can be an increase of the risk of violence against women according to some studies, can change the default for the frequency and severity during this period or even be initiated at this stage of a woman's life. Still, this type of violence ends up in invisibility in health services, and can cause risks to maternal and fetal health. Objective: To discuss the scientific production in Brazil in the period 2010 to 2015 regarding the children's maternal outcomes during gestation and postpartum women victims of violence perpetrated by an intimate partner. Methods: We used the scientific literature integrative review with cover articles in Portuguese, English and Spanish available in CINAHL databases, Scielo and BVS published in the periods 2010-2015 through descriptors in Portuguese and English "violence against women and pregnancy "," domestic violence and pregnancy. " Results: There was negative repercussions resulting from VPI, the analyzed studies bring these can affect both the pregnancy, such as puerperal, with higher occurrence of risk among women with unplanned pregnancy, abortion practice, presenting also high rates of gestational and postpartum depression, at high risk of suicide, poor quality in prenatal care, Fetal death (neo and postnatal) and increased risk of low birth weight. Conclusion: The knowledge of these data IPV during pregnancy by health professionals can help prevent negative outcomes for women's health and fetal development, and must become concrete action of primary care and specialized in prenatal care.

In recent years, companies have used Artificial Intelligence (AI) techniques to facilitate the decisionmaking process in manufacturing systems. The use of these techniques allows increased performance of Flexible Manufacturing System (FMS). The automation of the process using computational resources allows a deeper analysis of the system conditions, which sometimes result in a better decision taking. In this sense, the Fuzzy Logic has been engaged to carry out this task, because it has the characteristic of dealing easily with inaccurate information and encoding knowledge specialist in Fuzzy rules. However, as soon as the system complexity increases, the task of generating a Fuzzy Rule Base (FRB) appropriate to the proposed system becomes increasingly difficult. To assist this process of generation of the FRB, several techniques can be used and among them stand out the search technique called Evolutionary Algorithm (EA). The EA is used, for example, for tuning the FRB of the FMS through the reduction of the optimization variables values as Makespan or Tardiness. In the case of variable called Makespan, the tuning occurs when the EA generates an FRB that reduces the makespan values of a FMS. However, the construction of the EA that effectively generates a tuning FRB is not trivial. It is required to be in the process, the construction of various EA with different selection methods and different mutation rates among other settings until an appropriate EA for a given situation appears. Therefore, in this study we aim to build an environment configuration and performance analysis of EAs in order to define the tuning FRB of the Fuzzy Control System of an FMS, i.e., it is intended to investigate how the EA ideal parameter scenario used for tuning the FRB of the said control system. In this study, the used EA was an extension of Genetic Algorithm (GA). For implementing the proposal, an evolutionary system for configuration and analysis of this variant of the GA was created. In this system, entitled "EvolSys - Evolutionary System" parameters of the system as Number of Input Variables of FRB, Number of Output Variables of FRB, Population Size, Mutation Rate and the EA Crossover Rate, among others are configured and then, one FRB is generated. Using this, there is an EA analysis of the possibility for choosing a FRB that will provide the reduction of makespan in FMS. Consequently, through this study, we may conclude that the use of EAs in collaboration with Fuzzy system may become an important tool for turning the system responsibility to the sequences of an FMS operation. Accordingly, the environment created meets the configuration step and analysis of EAs.

This thesis describes a study of the electronic charge transport properties in antimony-doped tin oxide (ATO) ultrathin films, prepared by two different methods: by colloidal deposition process (CDP) and by pulsed electron deposition (PED). In order to determine the ultrathin films electronic transport mechanism properties and to elaborate a model for this mechanism, microstructural analysis and electrical characterization were carried out. The samples were studied by X-ray diffraction (DRX), transmission electron microscopy operating in high resolution (HRTEM), scanning electron microscopy (FEG-SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), ellipsometry, electrical resistivity measurements were made using the four-point probe approach from 20 to 300K and Hall effect measurements were made at room temperature. Regarding the CDP, DRX and HRTEM show nanocrystals with the cassiterite phase, highly crystalline nanoparticles and average crystal size of 6.5x4.4 nm. The FEG-SEM and AFM images indicate a crack-free deposition, constant thickness over the substrate cross-section and low roughness. Moreover, the electrical properties evaluation suggest that the experimental data fits the bi-dimensional Mott’s Law and that the electron hopping is in the order of the nanoparticles size. Concerning the PED, DRX indicates only the cassiterite phase structure and a preferential thin film growth at [110] direction, the FEG-SEM and AFM images show a homogeneous deposition and that the thickness is constant over the substrate cross-section, with low roughness. Besides, electrical characterization reveals a metal-semiconductor transition, that the experimental data fits the tridimensional Mott’s Law and that the electron hopping is in the order of the nanoparticles size. Thus, it is proposed that the charge transport mechanism obey the Mott’s Law, which occurs through the nanocrystals surfaces, i.e., the electron hooping occurs at preferential facets where there is Sb segregation.

The microbial community plays an essential role in maintaining the ecological balance of soil. Interactions between microorganisms and plants have a major influence on the nutrition and health of the latter, and growth-promoting rhizobacteria can be used to improve plant development through a wide range of mechanisms. Therefore, the objective of the present study was to evaluate bacteria as biological control agents to Phytophthora nicotianae and as growthpromoting agents for citrus rootstocks. Altogether were evaluated 30 bacterial isolates, 11 Bacillus spp., 11 actinobacteria, and 8 lactic acid bacteria. For P. nicotianae control tests at first was performed an bioassay with alfalfa seedling in order to select the most promising bacterial isolates for the biocontrol and, posteriorly, the best isolates were applied in Sunki mandarin (Citrus sunki Hort. ex Tan), and rangpur (Citrus × limonia Osbeck) by seeds and substrate microbiolization methods. It was evaluated the number of surviving plants, at 90 days after sowing and inoculation. The same Isolates also were evaluated in vitro for indoleacetic acid production, phosphate solubilization, and nitrogen (N) fixation. In vivo testing consisted of growth promotion trials of the bacterial isolates that yielded the best results on in vitro tests with three rootstocks: Swingle citrumelo [Citrus × paradisi Macfad cv. Duncan × Poncirus trifoliata (L.) Raf.], Sunki mandarin and rangpur. The parameters of interest were height, number of leaves, stem diameter, shoot and root dry mass, and total dry mass at 150 days after germination. The results showed that alfalfa seedling bioassay vi was able to evaluate the potential for biocontrol of bacterial isolates against to P. nicotianae, BL06 and BL12 (both lactic acid bacteria) showed potential to be used as biocontrol agents of disease, independently from the application method. BM16 and CPMO4 were able to promote growth of Swingle citrumelo. In Sunki mandarin plants, the best treatment results were obtained with BM17 (Bacillus sp.) and ACT11 (actinobacteria). For Rangpur lime rootstock, only BM05 (Bacillus sp.) was able to promote increase in two parameters assessed, height and number of leaves.

Defects play a fundamental issue on physical properties of wide bandgap semiconductors (WBS) due to the possibility of application in high temperature. This work shows the features of the defects in di erent kind of WBS grown/synthesized by solid state reaction, Pechini method and Molecular Beam Epitaxy. First we investigated the structural and optical properties of erbium- and manganese-doped strontium aluminates (SrAl2O4). The fundamental optical transitions due to Er3+ and Mn2+ are typical features of the well-diluted doping process. A signi cant enhancement of the Er3+ optical emission band at 1530 nm was observed when the matrix is co-doped with Mn. A model of energy transfer mechanism from Mn2+ to Er3+ is proposed to explain the experimental results. We present also the e ect of preparation and annealing conditions on the properties of Nb2O5. The increase of oxygen vacancies causes an inrreversible phase transition from pseudohexagonal to orthorhombic phase, and they are responsible for the increase in the e ective magnetic moments related to paramagnetic behavior. Finally, we explore the e ects of the interfaces imperfections of quantum wells of cubic GaN alloys. An indication of localized states in low temperature is observed. A decrease of this e ects happens when we increase the number of interfaces. Furthermore, magneto-PL measurements show a higher spin polarizations in the donor-acceptor impurities in the bulk of c-GaN corroborate for the importance of the defects. This work shows that the defects engineering in WBS are fundametal for developing new technologies in spintronics and optoelectronic eld.
