Investment casting of Titanium parts free of defects is very difficult owing to the reactivity of this element in the liquid state .The objective of this study was to evaluate the reactivity of titanium with refractory oxides of high thermodynamic stability, such as yttria and alumina. Centrifugal castings of small parts were carried out by melting the metal in an yttria coated crucible and pouring the liquid into molds coated with a mixture of yttrium and aluminum oxides. As binder for the powders were added colloidal suspensions of silica, alumina, yttria or zirconium acetate. Only the silica and alumina colloidal bonded the moulds with useful mechanical strength allowing the centrifugal casting trials. Both, yttria colloidal and zirconium acetate were excluded of the trials. By analyzing the hardness profile it could be noted that a similar curve was obtained for different moulds (oxides plus binder) related to the hardened layer thickness. However, the molds using a higher thermodynamic stability combination of binder and oxides presented lower Vicker values. The pair Yttria/Alumina colloidal induced less than 350 Vickers and Alumina/Alumina colloidal less than 720 Vickers on the surface of titanium as cast, for instance. Finally, a mathematical simulation of the process was proposed and it could be well adjusted and compared to the experimental graphics.

The present study had as objective to characterize the avian guild that consumes Miconia albicans and Miconia ligustroides fruits and also to describe the fenology of these plants. The study was carried out in a 124.68 ha fragment of cerrado vegetation, located in the Universidade Federal de São Carlos, campus São Carlos (21°58´ S, 47° 52´ W), São Paulo state, Brazil. Between March 2008 and February 2009, 30 plants of each species, random selected, were accompanied every 2 weeks and the number of floral buds, flowers, fruits and the percentage of new leaves were registered. During the fruiting periods, 96 hours of focal tree observations were made for each vegetal species, when the visitant birds, time and duration of visits, number of consumed fruits and the treatment given to the fruits were registered. M. ligustroides fruits were given to captive birds, to assess retention time of the seeds in their digestive tract. M. albicans fruited between October and January, coinciding with the wet season. During this period, 212 visits with fruit consumption were observed, performed by 19 bird species from 9 families. Species of the family Emberizidae were responsible for the majority of visits (34.9%), but the treatment given to the fruits allows to infer they are probable seed predators. Mimus saturninus and Patagioenas picazuro consumed the largest parcel of fruits (respectively 23.34 and 19.27%). M. ligustroides fruited between March and June, in the transition between wet and dry seasons. 101 visits performed by 15 bird species from 6 families were observed. Species of genera Elaenia performed the majority of visits (34.65%), followed by Tangara cayana (12.87%) and Schistochlamys ruficapillus (10.89%). Family Thraupidae species were, together, the most representative in number of visits and fruit consumption. Average duration of visits for each bird species was always less than 3 minutes, lower even than the smallest retention time observed at the captive birds experiment (Pitangus sulphuratus: 4.98 ± 1.53 minutes). Adding the fact that birds consumed the whole fruit in all observations made at M. ligustroides trees, it is posible that the observed birds are potential seed dispersers of this plant. M. albicans and M. ligustroides produce a large amount of small fruits with many diminute seeds. Their fruits are consumed by many bird species with generalist diets. Therefore, both elastomataceas utilize an opportunistic frugivore bird dispersion strategy. These data show that both species may be usefull in conservation programs for recuperation of degraded cerrado areas, but future studies are necessary to verify the dispersive potential of the birds here registered, just as to know the germination and seedling establishment characteristics.

For the artisanal cachaça production, which is a beverage obtained after distillation of the fermented sugar cane juice, natural starter ferment ( caipira ferment) is utilized, in which crushed corn, rice bran and citric fruit juice are added to sugar cane juice. The primary source of microorganisms, yeasts especially, is the sugar cane juice itself, and although the cachaça sensorial quality is recognized when this ferment is utilized, there are some inconvenients as difficulties in the quality control due to the high level of contaminants and extensive preparation periods. In this context, this work aimed the evaluation of microbiological (yeast numbers) and physico-chemical aspects of the juice extracted from 10 sugar cane varieties, in three harvesting periods (May, September and December) in an area under organic management. The same analysis were performed for the juice extracted from different stalk sections (lower, medium and upper section) from three sugar cane varieties (RB72454, RB835486 e RB867515) under organic management, seeking for information which could contribute to the variety management allowing a faster and efficient natural ferment preparation. A significant decrease in the yeast numbers (CFU/mL) in the juice were observed when the maximum point of maturation was reached for the majority of the varieties. However, the proportion (%) of Saccharomyces increased with the sugar cane maturation, in such a way that early and medium maturation varieties (RB835054, RB835486, RB845210 and RB855156) may be utilized at the beginning of the harvest period (in May) for the natural ferment preparation, which could result in diminished preparation time and faster fermentation. Among the early maturation varieties, RB845210 is indicated because it also presented high reducing sugar and protein in the juice. Regarding the juice extracted from different stalk sections, the upper section (from 11th to 15th internode, without the palmito ) could be indicated for the natural ferment preparation because of higher yeast numbers, higher reducing sugar concentration and acidity, which promote the yeast growth. It was verified that Saccharomyces yeasts show a transient and spatial distribution along with sugar concentration gradient. The knowledge of this behavior and variety characteristics can ease the variety management aiming the production and performance of the natural starter ferment, in order to contribute for the organic cachaça production.

Inflammation is the response of protection of the body to an aggression in order to obtain the healing. This process makes part of many diseases attended by physical therapist, however when it is increased, limits the fast recovery of the patient. High voltage pulsed current (HVPC) is one of the modalities used to interview of inflammatory process; the type of stimulation is considered monophasic pulsed that produces a high-driving voltage 150 V, but the total current (average) delivered to the tissue per second does not exceed 1.2 to 1.5mA. There are many studies that evaluate the effect of HVPC in swelling, but the major part was made in animal models and only one in human beings was found in the review of the literature. The results of the studies in animals had showed the effectiveness of HVPC in reduction of edema, but the study in human only showed clinical differences not statistically significant. Additionally, the action mechanism of HVPC is unknown and some hypotheses have been proposed for explaining its effect. The objective of this study was evaluate the effectiveness of HVPC in the inflammation process, both in humans and animals in a submotor level, 100pps of frequency and 45min of treatment. We made a controlled and randomized clinical trial in subjects with lateral sprain of ankle measuring pain, edema, range of mobility and some parameters of the gait comparing three groups: control group (CG) with standard physical therapy, HVPC(-) with standard physical therapy plus HVPC negative polarity and HVPC(+) with standard physical therapy plus HVPC positive polarity. There was not difference between the study groups, but the clinical results suggested that HVPC(-) could contribute to accelerate the recovery of inflammatory process. Second, an experimental study was done in animals evaluating pain, edema, serum histamine and albumin and the cartilage, comparing a control group, a inflammation group with HVPC(-), a inflammation group with HVPC placebo and the last group only with HVPC(-). We did not find differences between the groups in the variables, only observed the lowest cellularity in the cartilage of inflammation group+HVPC(-) and lowest optical density in inflammation group+HVPC placebo. These results are a contribution for the understanding of the biophysical agent used in the physical therapy, however is necessary more clinical studies including higher sample size, in order to demonstrate the effects of HVPC on the inflammation process.

This manuscript is the result of a master s research aiming at describing and analyzing the professional paths and pedagogical practices of four music teachers that taught music in the interior of São Paulo State when the music was a compulsory course in Brazilian schools, from 1952 to 1971. These teachers lived through a period of transition and adaptation when music lost its curricular standing and was subsumed by a broader subject, Arts Education, in 1971. The research, of a qualitative nature, adopted the oral history method with emphasis on memory. The data were collected by means of semi-structured interviews and journals written by the participating teachers were used as a memory resource the analysis of the data was based on the theories of Paulo Freire and Ernani Fiori, in a Latin American perspective. Eclea Bosi, provided the foundation for the analysis of the teachers memoirs, and Fonterrada, and Joly informed the research with respect to music education. Nóvoa, about the teachers' life course and history. The analysis disclosed significant events in the personal histories of these music teachers and shed light on a period of Brazilian music education. The analysis of the significant moments in the participants careers promoted the knowledge on the environment of music education during a specific period of time and contributed to a more informed understanding about music, schools and teaching careers in Brazil.

This study aimed to compare the effects of a conventional program of exercises in groups with a program of resistance exercises, with respect to the following variables: systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), waist circumference (WC), flexibility, handgrip strength and strength of lower limbs in knee extension. A total of 60 individuals participated in the present investigation, residents of São Carlos, of both sexes and aged over 50 years. The subjects were sampled by convenience and were divided into three groups: Control Group (GC), composed of 22 people who doesn t were engaged in any monitored and supervised physical activity, Group A (GA) formed by 21 subjects who underwent a program of physical activity in a conventional group, and Group B (GB) consisting of 22 individuals who participated in a program of resistance exercises. The measurements were made using a stethoscope and blood pressure gauges for measuring the BP, an anthropometric scale for measuring weight and height, a tape measure to check the CA, Bank of Wells for flexibility, and a manual dynamometer and isokinetic dynamometer to measure the handgrip muscular strength and knee extension, respectively. All subjects underwent an initial evaluation that consisted of: history, blood pressure measurement, body mass index calculation, measurement of CA, flexibility and muscle strength. Having been assessed, the volunteers in Group A began a program of exercises in the conventional group, which aimed to develop physical abilities such as flexibility, aerobic endurance, muscular strength and coordinating skills involving balance, agility and pace. This program was performed three times per week, each session lasting 50 to 55 minutes. The volunteers in Group B participated in a program of physical resistance exercises. The machines were the leg press, calf, back extension, abdominal, bench Press and rowing, and were used according to the periodicity of the training, with a frequency of three times per week and duration of 50 minutes per session. New measures were taken after intervals of three and six months as from the initial assessment of all groups. The statistical analysis was performed by way of a nonparametric analysis using the Kruskal-Wallis, Friedmam test, Wilcoxson test and Friedmam test replicated to two factors. As a result it was possible to observe a significant reduction in the SBP, DBP and BMI in Group B, significant reduction of WC in Groups A and B, increase in muscle handgrip strength after three months in Group A and after six months in Group B, significant increase in flexibility in both Groups A and B and significant reduction in strength in the knee extension at 60°/sec in Group A. Thus it was concluded that for all the variables, except for the strength of knee extension, at least one of the groups that underwent intervention showed significant improvements when compared to the control group. When the two programs were compared, the Geriatric Revitalization program was more effective for the variables of handgrip force and knee extension at 60º/sec. and at 180°/sec., while the program of resistance exercises generated better responses for SBP, DBP, BMI and WC.

Microarrays technologies are used to measure the expression levels of a large amount of genes or fragments of genes simultaneously in diferent situations. This technology is useful to determine genes that are responsible for genetic diseases. A common statistical methodology used to determine whether a gene g has evidences to diferent expression levels is the t-test which requires the assumption of normality for the data (Saraiva, 2006; Baldi & Long, 2001). However this assumption sometimes does not agree with the nature of the analyzed data. In this work we use the skew-normal distribution described formally by Azzalini (1985), which has the normal distribution as a particular case, in order to relax the assumption of normality. Considering a frequentist approach we made a simulation study to detect diferences between the gene expression levels in situations of control and treatment through the t-test. Another simulation was made to examine the power of the t-test when we assume an asymmetrical model for the data. Also we used the likelihood ratio test to verify the adequability of an asymmetrical model for the data.

The use of restricted access media columns for direct injection of samples chemically complex is consolidated, but not for environmental samples. This work describes the conditions for exclusion of aquatic fulvic and humic acids. The analyses were performed comparing the areas obtained after direct injection of standards in a chromatography column of gel permeation (Tsk gel® G3000PWXL), and those obtained in in-line mode with the RAM-BSA. Through a calibration curve, using standards of sodium polystyrene sulfonates of different molecular weights, in order of the 18000 Da, the molecular weight of eluted fractions were determined. This work reports the development, validation and application of sensitive, precise and accuracy methods, by high performance liquid chromatography with direct injection of samples for the enantioselective determination of omeprazole, lansoprazole and pantoprazole drugs in environmental matrices (wastewater from the city of São Carlos, Brazil and estuarine water of the River Douro, Porto-Portugal). The methods were developed by multidimensional liquid chromatography using an octyl restricted access media bovine serum albumin column (RAM-BSA C8) in the first dimension for the exclusion of macromolecules and extraction of drugs. The enantiomeric separation of omeprazole was achieved in the second dimension with a chiral column, amylose tris (3,5-dimetylphenylcarbamate) coated onto APS-Nucleosil support, and the chiral column amylose tris (3,5- dimethoxyphenylcarbamate) coated onto APS-Nucleosil support it was used for simultaneous enantiomeric separation of lansoprazole and pantoprazole. Aliquots of 500μL of the samples were injected directly into the multidimensional chromatographic system with detection for ultraviolet-visible spectroscopy (UV-vis). The quantification limits obtained for the enantiomers of omeprazole were 15μg.L-1, and for the enantiomers of lansoprazole and pantoprazole 5.0 and 7.5μg.L-1, respectively. Lower quantification limits were obtained for the enantiomers of lansoprazole (0,60μg.L-1) and pantoprazole (0,40μg.L-1) by replacement of the UV-vis detector for the mass spectrometer in a multiple reaction monitoring (MRM) mode and increasing the injection volume for 1000μL.

The goal of this study was to develop a program of object-playing tasks to teach nameobject relations, and to verify its effects on learning reading and writing. To teach reading participants were exposed to a computerized teaching program based on the stimulus equivalence paradigm. Thirteen students, aged seven to ten years old, participated in both teaching and object-playing tasks. These tasks were organized in three conditions. Condition one (Object) taught objects naming and the second Condition (Ilustration) taught pictures naming. In both conditions, the tasks made use of words that were taught in the reading and writing procedure. The third condition (Control) taught picture naming as well; however, these pictures were different from those used in the teaching program. Nine words were taught, three familiar, three nonfamiliar and three pseudo-words. The object-playing tasks were always completed before the teaching phases that targeted non-familiar and pseudo-words. Four students were assigned to the Object Condition, four were assigned to the Illustration Condition, and five were assigned the Control Condition. A multiple baseline design across words was used for the analysis of individual performances in reading acquisition. The number of assessment sessions varied across participants, from 11 to 54 sessions. This meant that participants had to be exposed to many sessions of retraining. It was observed that, regardless the teaching condition, the number of teaching sessions was fewer for learning familiar words than it was for learning non-familiar and pseudo words, which suggests that familiarity is a relevant variable in the reading acquisition. All participants learned to name the objects or pictures that represented the aimed words of this study, implying that object-playing tasks were efficient to teach the name-object relations. However, the results did not indicate differences between Object and Illustration conditions concerning reading acquisition. These results also suggest that the material format did not have a critical influence on the number of assessment sessions completed by participants. Instead, the critical variable on reading acquisition was the establishment of matching printed to dictated words from which reading emerged.

This research aims to investigate the social meaning of the public school English teacher s work and the personal sense he/she attributes to his/her teaching activity. To achieve this objective we used as theoretical basis the sociohistorical approach and the Activity Theory which was developed by Leontiev (1978; 2004). In order to understand the social meaning that is associated to the English teacher s activity we surveyed authors who deal with relevant issues about language learning and teaching (ALMEIDA FILHO, 1993, 2003; MOITA LOPES, 1996, 2003, 2008; PAIVA, 2003, 2008; CELANI, 2005; LEFFA, 1999, 2003; PENNYCOOK, 2008, among others) and we also reviewed official documents for the Brazilian educational public politics (Parameters, Orientations and National Curricular Proposals for the teaching of Foreign Languages). The research methodology involved the application of a questionnaire to twenty-six English teachers of public schools from a countryside city of the state of São Paulo. With the help of this instrument, we gathered data that allowed us to outline the present profile of those teachers and to obtain information on several aspects involved in their daily work. We aim to answer the following questions: (1) Which social meanings are attributed to the activity of the public school English teacher? (2) Which personal sense the public school English teacher attributes to his/her work? and (3) Which relation can be established between the social meaning and the personal sense related to the teaching activity? By exploring the multiple variables involved in the public school English teacher s work and by verifying the meanings and senses associated to his/her teaching activity, this study may contribute to a better understanding of the conditions that involve that activity, by allowing the problematization of values and attitudes that guide and ground the teaching of English in the context of public schools.

The rubber industry is a sector that contributes significantly with the national economy due to the fact that it is part of a wide range of products. Therefore, we verified the need of a terminological systematization in this field. Based on this fact, our objective is to elaborate a monolingual vocabulary (glossary) of rubber goods in the automotive sector, with English equivalences. This paper is supported by the Communicative Terminology Theory proposed by Maria Tereza Cabré. Under a communicative perspective, the methodology of this research contemplated the compilation of a corpus as well as the utilization of a computer tool, the Unitex, in order to manage the texts that make part of this corpus. We extracted words (semi automatically) which we considered a term candidate, inserted them in the ontology, elaborated and filled out the terminology forms which were used as a term dossier; elaborated a text definition basis which was constantly fed with new information and sequentially we wrote the definitions. The definition texts of the rubber vocabulary (glossary) are based on the researches at Terminology Group Studies department GETerm. The microstructure - headword - contemplates systematic (obligatory) and asystematic (non obligatory) information that facilitates the peoples use. Concerning the vocabulary/ glossary microstructure we followed the TERMICAT s (1990) proposal, which aims the specialized communication.

Despite being widely distributed in South America, the South American Terns (Tierra del Fuego to Bahia and all around the Pacific coast to Peru), and Cayenne Terns, (from the Caribbean Islands to the region of Deseado Port), and having relatively large populations, little is known about the ecology of these species in the Neotropical region. The present study is a contribution to the knowledge of the reproduction and trophic ecology aspects. Samples were taken daily on the Cardos island, SC, Brazil, along 2003, 2005, from 2006 to 2008, aiming to characterize the reproductive ecology of these species. The season of 2003 began with the arrival of the first adults in mid-May, and in 2005 and 2006 occurred in late April, with the departure of adults in early October. 2486 nests of S. hirundinacea were recorded in 2005 to 1,852 in 2006, with average clutch size ranged from 1.45 in 2006 to 1.19 in 2003 and the hatching success in 2006 was estimated at 82.16%. While for Thalasseus sandvicensis in 2003, it took on average 23.5±0.2 days for the hatching of chicks, and success of 83.33%. Was recorded 6,248, 5,140 and 4,006 preys transported by S. hirundinacea and 1157, 628 and 98 by Thalasseus sandvicensis for the colony during seasons of 2003, 2005 and 2006, respectively. The delivery of food to the chicks occurred since the early hours of the morning until late afternoon. The first chicks hatched in July 2003 and June 2005 and 2006, with reproductive success for S. hirundinacea of 50.94%, 35.96 and 53.47%, and Thalasseus sandvicensis of 48.00, 29.94 and 5.00%, respectively. The highest growth rate for S. hirundinacea occurred in the first 20 days of life with small increments until the flight and subsequent abandonment of the island around 46 days in 2003, 45 in 2005 and 42 in 2006. The small size of the island, the human low pressure and little activity of the gull (Larus dominicanus), considered the main predator on the Brazilian coast, during the egg laying period, allowed the regular occupation, making it an important site for the conservation of these species.

The main concern of this work is related to the development of an aggregate production planning model of a cooperative society of sugar and alcohol milling companies. This mathematical model is based on a hierarquical approach between the annual planning problem of the cooperative and the tactical planning horizon of the sugarcane mills. In the cooperative level the main questions are related to the allocation of production goals to each mill and the management of inventory and dynamic demands. In the milling companies level a process selection model aims at helping the decision makers to determine the quantity of sugarcane crushed, the selection of sugarcane suppliers, the selection of sugarcane transport system suppliers, the selection of industrial process used in the sugar, alcohol, molasses and energy production. Besides that, this work presents an analysis of the impact of uncertainties in the aggregate planning problem parameters, using robust optimization techniques. To solve the linear and mixed integer mathematical problem found in this modeling, we applied a state of the art modelling language with an optimization solver. A case study was developed in a cooperative of sugar and alcohol milling companies located in the state of Alagoas- Brazil and at Santa Clotilde mill, located in the city of Rio Largo-AL. The results of this case study helped us to verify the applicability of the proposed models in the aggregate production planning of the studied organizations. Computational results are presented and analyzed with real data application.

The exposure of animals to aversive situations, such as elevated plus-maze (EPM), activates serotonergic pathways with projections into structures involved in the defense system, such as the amygdala, septum, hypothalamus, hippocampus and periaqueductal grey matter (PAG), producing behavioral changes that can be characterized as anxiety. However the serotonin (5-HT) presents a dual role in this modulation. Thus, while the stimulation of the receptor subtype 5-HT1A and 5-HT2 prosencephalic in structures such as amygdala and hippocampus result in potentiation of responses of anxiety in rodents, the activation of these receptors in the PAG, often tends to reduce behaviors related to anxiety . This study focused the role of 5-HT3 receptors in the PAG in the anxiety in the mice EPM test. In experiments 1 and 2, mice received infusions intra-PAG of ondansetron (0, 0.3, 1.0, 3.0 nmol/0.1 μL) and mCPBG (0, 40, 80 and 160 nmol/0.1 μL), 5-HT3 receptors antagonist and agonist, respectively. As the mCPBG not changed any of the conventional indices (% open-arm entries and % open-arm time) and risk assessment, we investigated in experiment 3 the possibility of interaction between 5-HT3 and 5-HT2 receptors. For this, we perform combined microinfusions of intra-PAG ondansetron and mCPP, an agonist of 5-HT2B/2C receptors, on behavior of maze-naïve mice. The results showed that intra-PAG infusions of ondansetron (3.0 nmol) increased the behavioral indices of anxiety. None of the doses of intra-PAG infusions of mCPBG modified the conventional and ethological indices of anxiety. The anxiolytic-like effect produced by intra-PAG infusions of mCPP (0.03 nmol) was blocked by infusions of ondansetron (1.0 nmol) in the same mesencephalic structure. All effects were observed in the absence of significant changes in locomotor activity (closed-arm entries). Our results indicate that there is a possible interaction between 5-HT3 and 5-HT2B/2C receptors modulation into the PAG of anxiety in mice.

The making of the definitions is the most complex step in terminological research which aims to compile specialized dictionaries, for the good ones are evaluated mainly as to the quality of their definitions. As there are differences between terms and words, there are also differences between defining them. While the lexicographic definition specifies and describes the meanings of words as language units, giving all their possible senses, the terminological definition (TD) identifies and describes terms only in reference to the specific conceptual system to which they belong. Therefore, the TD is the object of this Master s study. Our undergraduate experience in terminological research in the Group of Studies and Research in Terminology (GETerm), revealed several difficulties associated with the TD process. The defining method was changed, adapted, extended, and revised to handle the challenges of the research. From that experience, we came to a set of methodological procedures to aid the TD routines in any domain knowledge. Accordingly, this Master s dissertation research aims to systematize those procedures to be implemented into a Web-based, computational environment (E-Termos) to aid research groups in their terminological endeavor.

The lack of sanitation systems is one of the main causes of insalubrity and environmental degradation. The term sustainability has provoked a debate in the literature, derived, mainly with the environmental concern and the use of the non-endless natural resources. Besides environmental and ecological issues, the concept incorporates the economical, social, cultural and political dimensions. The last one emphasizes the people participation on making decisions, management and general control of the production process, through the comprehension of the reality and the analysis of different alternatives. The use of participatory processes for taking decision to the choice of more sustainable domestic wastewater system, besides easing the knowledge transfer, permit access to the nonconventional techniques. General purpose was to analyze the strategies, conditions and obstacles for the implantation of more sustainable domestic wastewater systems, containing as experimental object the Rural Settlement Sepé-Tiaraju, located in Serra Azul-SP (Brasil), considering the participatory process for families taking decisions. General strategy used was the participatory action research, which the researcher and the families interact with each other in a cooperative and participatory way. General steps of the action were: 1- participatory process for domestic wastewater systems choice; 2- executive project and the budget system; 3- execution plan of the pilot system; 4- family organization for the execution of the pilot system; 5- the execution of the pilot system; 6- the system maintenance and utilization instructions. For each verified hypothesis, it was elaborated a spreadsheet in where it was explained: the type of information (variable), the evidence sources, the proceedings for the data collection and analysis. It was used as evidence sources the reports, the spreadsheets, the audiovisual images from the discussion meetings with the families and the execution of the domestic pilot wastewater system. Products were: 1- characterization of the domestic wastewater system choice by participatory process for the case of rural settlement Sepé- Tiaraju; 2- characterization of the domestic pilot wastewater system execution by participatory process; 3- sustainability and the participatory action research analysis for the more sustainable domestic wastewater system implantation. Results indicate that the use of participatory process enables the information access, the choice of non-conventional techniques and more sustainable, although it takes more time of the evolved actors (researcher and families) and the adequacy of the activities to the social reality and the capacity of comprehension of the participants. Challenges are related to the actors governance, conflicts and financial resources governance, besides the match of disposable time for the research and the action in the social reality.

Many are the productions already developed about nihilism in Nietzsche s work, wich the perspective of unconditional affirmation of the world and life is assumed as an inevitable consequence on the overcomig of nihilism itself. However, even admiting that Nietzsche s thougth about nihilism conducts him to an unconditional affirmation of every happening, our research is developed by the nitzschean notion of redemption. Since The Birth of Tragedy, Nietzsche explores the theme in the reconciliation fullfilled by the tragical art between the apollonian and dionisian.In his work of 1872, the philosopher finds in Dionysus shapes a god that affirms the suffering, wich is a crucial subject to the future guiding of his supreme-affirmative thought. In contrast to the tragical conception that was formed as a way to escape from the pessimism, the socratism-platonism is understood by Nietzsche as a movement that puts in progress the nihilist logical in the West, consummated on the christian conception of negativity. In front of a terrible diagnosis presented by Nietzsche in his works of maturity, we ve try to show in what measure on one hand, answering to the question about provenience of nihilism, in the other hand, explicitating it s developing on moderness, Nietzsche s philosophy is able to think radically on the overcomig of nihilism, reaching expressively in the project of transvaluation with the same notion of human s redemption.

The central objective of the research was to study the presence of women in legal careers working as a district chief of police, which is traditionally a male profession. For the development of this research were used two sources of analysis. The objective of the first was to examine women's participation of the profession through the statistics on this professional group. The objective of the second was to evaluate the Women s Police Stations to enable people to verify if the market reserve established by this institution contributed to a process of subordination of these professionals in comparison to their peers. The study made it possible to find out that, on one hand, the inauguration of the DDM's (Delegacias de Defesa da Mulher) channeled more women to work in these stations, on the other, contributed to an "imprisonment" of their career. This is because, for many chiefs of police, working in a DDM is considered an obstacle for the career. We also examined the social representations that the DDM developed at the corporation's police and within the profession of delegate of police, and what has changed in the structure and image of those police stations for the police profession. The study was conducted in São Paulo, where police districts were studied and DDM s. The study was conducted from 2007 until 2009. As a research methodology, interviews were done with chiefs of police from DDM s and police districts in order to establish a comparison between these organs. Altogether 12 interviews were conducted, and with 9 women and 3 with men.
