The goal of the dissertation is the comparison of fantastic tales of the romantic writer Edgar Allan Poe (1809-1849) and the Brazilian writer, who also produced stories of the fantastic genre, Machado de Assis (1839-1908). The predominant issue is how the two authors who lived in different eras and in different countries so diverse socioeconomically may have their supernatural works compared. To answer this disturbing question, some clues of Poean influence on the fantastic tales from the Brazilian writer were obtained, such as the celebrated translation of Poe's poem "The Raven" (1845), made by Machado (or "O Corvo", as translated by himself in 1883); it is also important to our studies to analyse the quotes in newspapers in which Machado wrote, such as o Diário do Rio de Janeiro (1866) and Gazeta de Notícias (1895), as well as the comparison between the short stories “O Espelho” (1882) and “Sem olhos” (1876), by the Brazilian writer, and “William Wilson” (1839) and “Ligeia” (1838), by Poe.

The present study investigated the utilization efficiency of an intermeshing co-rotating twin-screw extruder (ICTSE) in the devulcanization of natural rubber compounds (NR), evaluating the physical, chemical and mechanical characteristics of these materials in each project step. Three accelerated compounds with different sulfur concentrations were submitted to torque rheometry and vulcanized according these results aiming the achievement of elastomers with different crosslinks densities. The influences on the characteristics of the devulcanized material caused by the variation of the extruder barrel temperature, screw rotation, thermoplastics addition and material stiffness were evaluated. Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR), soluble fraction extraction and crosslink density were performed, evaluating the devulcanized compound. Horikx's theory was also used as an indicator of selective crosslink cleavage, defining the compounds to be revulcanized for comparison with the virgin pure material. The revulcanization was carried out with the mixture of the devulcanized compound with the pure, in the proportions of 30/70 w/w, respectively, and in the devulcanized compound singularly, with addition of complementary vulcanization system in both cases. The mechanical, dynamic-mechanical and crosslink density properties of the revulcanized compounds were characterized and evaluated in relation to the properties of the pure compounds. The increase in the concentration of uncrosslinked BN chains and the concentration of sulfur compounds in the extruded samples was observed by thermal tests and spectrocopy, together with the verification of a high level of devulcanization percentage, according to Flory-Rehner, evidencing the regeneration of the natural rubber existent. Also, satisfactory mechanical properties were found in the revulcanized compounds, especially when using auxiliary thermoplastics, revealing the great potential of ERDCI processing for the reuse of discarded BN compounds.

In the problematization of the insertion of the desire by disability, as sexual or identity pathologies, this project proposes an incursion into the terminology and biomedical configurations on the subject in order to understand which discourses are triggered when it is sought to discriminate as ‘sick’ those and those who seek to relate erotically to the disabled or who want to cause disabilities in their own bodies. For this, the intention is to investigate the clinical bibliography produced on devotees, pretenders and wannabes, aiming to systematize to the maximum historically the continuities and discontinuities in the creation of these 'pathological types'. Concomitantly, aiming to establish a critical dialogue with the biomedical knowledge on sexuality and disability, I propose a more theoretical theoretical incursion into one intersection between disability studies and queer theory, the so-called crip theory.

La corrida de calle es un fenómeno que se ha destacado en los contextos urbanos brasileros, consolidándose, inclusive, como el segundo deporta más practicado en el año 2011. En este contexto, el/la corredor/a se ha transformado en una figura estratégica para reflexionar a respecto de las producciones y reproducciones corporales y subjetivas de la época actual, marcada por una competitividad e el paradigma de la auto superación. A partir de lo expuesto, los objetivos que orientan la investigación consisten en a) analizar la producción de determinado tipo de subjetividad característico de la práctica de corrida para b) reflexionar sobre los diálogos con un tipo de racionalidad que caracteriza al sujeto neoliberal. Para responder a esos objetivos, desarrollamos una investigación etnográfica en un período de dieciocho meses en la ciudad de São Carlos, interior de São Paulo, en la cual buscamos acompañar dos grupos de corrida de hombres y mujeres, caracterizados por diversos niveles de compromiso con la práctica. Con la finalidad de presentar los resultados de la investigación etnográfica y bibliográfica, el texto se presenta dividido en tres secciones. En la primera sección, trabajamos con la construcción de una estética corporal vinculada a la salud y a la cualidad de vida como caminos posibles de elección, así como la construcción de una matriz moral en torno a esas dimensiones. En la segunda, nos focalizamos en el análisis de los elementos que permiten una comparación con la figura teórica del hombre-empresa. Finalmente en la tercera sección, abordamos la producción y reproducción del dolor y el placer así como los diálogos con el tipo de subjetividad neoliberal

The present dissertation aims to analyze three essays from the german philosopher Immanuel Kant that deal with his philosophy of history, highlighting within them the concept of unsociable sociability. The essays are: Idea for a Universal History from a Cosmopolitan Perspective, Conjectural Beginning of Human History and Toward Perpetual Peace. In our understanding, it is possible to assume the idea of antagonism as a guiding thread of an analysis of Kant's philosophy of history, insofar as it is shown that for the philosopher the unsociable sociability is the source of all human progress. Our objective is to highlight three historical philosophical moments in the analyzed texts, and to demonstrate how antagonism is responsible for the passage from one moment to another, thus, corroborating its importance.

Convenience food can provide individuals with savings in time and effort – both physical and mental – at all stages of food provisioning, from meal planning to cleaning up. In this sense, its consumption fits into the contemporary changes in eating habits, attitudes towards the act of cooking, and also into increasingly stressful lifestyles. Although there is an increasingly shift on the demand from raw foods to foods with some degree of convenience in Brazil, national studies portraying this topic are still scarce. In order to contribute to this debate, this thesis proposes a conceptual model relating attitudinal and socio-demographic variables – directly and indirectly – to the declared consumption of convenient food. This framework is based on premises of two main theories: the theory of domestic production and the convenience orientation approach. The methods we employed include a systematic bibliographic research, followed by a survey with consumers of the state of São Paulo. In order to test the proposed hypotheses we employed a structural equation modeling approach based on a valid sample of 1391 consumers. The use of convenient foods was mainly promoted by an individual’s convenience orientation on the food provisioning process, in the stages of meal planning and preparation and cleaning up, and by an individual’s perception of time constraint. The main attitudinal factors that are likely to restrict the consumption of those products were the desire to keep a healthy and natural way of eating and the pleasure achieved by culinary activities. Based on the impact of certain attitudinal variables on the use of convenient foods, the results deepen the discussion regarding the set of factors supporting the growth of the trend of convenient food consumption in the Brazilian market. By understanding the dimensions of this trend, food manufacturers are able to better seize the emerging opportunities to position their products successfully in the market.

The main objective of this research is to understand the transition modes for the adult life of University students. From comprehensive interviews guided by a semi-directive script, we sought to understand a set of experiences and challenges - especially in the University, in the world of work and in family life - that could be revealing of the processes of transition to adult life lived by ten young people - five girls and five boys - who study at the Federal University of São Carlos - Sorocaba campus. Held between the years of 2015 and 2016, the study focused on students from different courses and social insertions who had already attended at least half of their degree. The analysis of their narratives evidenced a multiplicity of trajectories, which are characterized by non-linear biographical pathways. The study revealed the importance of the new policies of access and permanence in the University, which have promoted a growing heterogeneity of subjects in a space historically restricted to the elites. In addition, it was possible to observe that while the trajectories are increasingly heterogeneous and unique, structural issues - especially linked to social origin and gender - appear as common challenges to be faced by girls and boys in their processes to conquer autonomy and Independence.

How does the arrival of foreign medical professionals, working mainly in health posts with Brazilian physicians, in the context of the implementation and validity of the "Mais Médicos" program, has stressed the discourses of professionalism and what are the effects of this contact for professional identifications? Different types of professional training, with varied or contrasting approaches, within the same profession, have produced competitive discourses of professionalism, given the same work position? Starting from the official speeches of the institutions of the Ministry of Health and representative organs of the medical profession, I sought to understand how physicians, in their daily lives, have built and have negotiated their identities and negotiate the discourse of professionalism, and how they have positioned themselves in this debate and deal with the differentiation introduced by public police. The fieldwork, consisting of 14 qualitative interviews and the analysis of the discourses from different organs, actors and publications expressing the clash around the program, have allowed us to understand how the processes of reworking and negotiating these discourses and identities occur, and how they appear and are disseminated in the speech of physicians working in the municipality of São Bernardo do Campo, located in the metropolitan region of São Paulo.

Amazonian floodplains are complex networks that play relevant roles in global biogeochemical cycles, and the bacterioplankton degradation of organic matter is key in regional carbon budget in these systems. The Amazon undergoes seasonal variations in water level, which produces changes in landscape and in sources of organic inputs into floodplain systems. Although these changes should affect bacterioplankton, no studies have addressed the question of which factors drive spatial and temporal patterns of bacterioplankton in these systems. We used high-throughput (Illumina MiSeq) sequencing of the V3-V4 region of the 16SrRNA gene to investigate the spatiotemporal patterns of bacterioplankton community at different diversity layers and size fractions, and their correlation with environmental variables in an Amazon floodplain lake. Overall, four phyla dominated the community throughout the study: Actinobacteria, Cyanobacteria, Proteobacteria and Planctomycetes, but their abundance were different between size fractions, hydrologic periods and influence area. The rare biosphere had an important contribution for the composition patterns of all community and showed be more influenced by the spatial complexity. We found that the floodpulse was the mainly drive force of community composition patterns for the free-living fraction, and the distance from the Amazon river was the main driver for the particle-attached fraction. We also found differences between the combination of local and regional factors across space and time shaping the community. This is the first detailed characterization of the bacterioplankton community composition in an Amazon floodplain lake and we demonstrated that the spatial and temporal complexity of this system were reflected in bacterioplankton community composition.

Sintering additives (AS) have great potential to be applied in refractory castables as they reduce the densification temperature of these products. Additionally, these components may induce the generation of a transient liquid phase in the microstructure at high temperatures, which can react with the other materials of the composition to give rise novel solid refractory phases. Considering these aspects, the present work evaluated the role of five different AS (boron oxide, boric acid, sodium borosilicate, magnesium borate and boron carbide) when added to alumina-based castable compositions containing hydratable alumina as binder. Based on the thermomechanical characterization, XRD analysis and the in situ elastic modulus measurement, boron carbide (B4C) have been selected as a promising AS because this material sped up the sintering process at lower temperatures and induced the aluminum borates formation due to the reaction between the liquid phase and the fine alumina contained in the castable matrix. Afterwards, the effects of B4C was evaluated in ultra-low calcium oxide castables bonded with: colloidal alumina (AC), hydratable alumina (AB) and/ or SioxX®-Zero (SZ). SZ-bonded materials (4 wt.%) had good performance at temperatures around 1100°C due to the mullite generation. On the another hand, castables containing AC as binder (4 wt.% of solids) and 0.5 wt.% of B4C are promising options to be used in working conditions between 600-815°C, whereas the same mixture without B4C could only be densified above 1100°C. Similar effect was observed when 1.0 wt.% B4C was added to SZ-containing castables as the aluminum borates generation allows these compositions to be used in working conditions around 815°C. Therefore, an appropriate AS selection for high-alumina castables with ultra-low CAC content has the potential to favour the earlier sintering of the refractory and improve its thermomechanical properties, which can fulfill the requirements of the petrochemical industry.

The present work analyzes the representations of the city Rio de Janeiro in literary texts of Machado de Assis and Lima Barreto. This study determines the type of evaluation that these writers made of the modern aspects of the capital of Rio de Janeiro. The chronological framework is between the last two decades of the nineteenth century and the first years of the twentieth century. The initial assumption of the research considered these writers as skilled observers of the social environment in which they lived. Another presupposition is that the nineteenth-century literature constitutes an important collection of visions about the urban (both in Europe and in Brazil). Thus, Machado de Assis and Lima Barreto are analysts of urban life in Rio. The basic unit of research analysis is the category of representation. Its application is through the methodology of selection of texts from the set of complete works for further analysis. The detailed reading of fragments is done in order to identify images and allusions concerning the urban universe. The analysis carried out demonstrates the existence of representations of sociability and urban sensibility in the literature of the mentioned writers. The novels “Esau e Jacó” and “Triste fim de Policarpo Quaresma” bear a set of representations about Rio de Janeiro that describe the way of life of a capital during the period that was designated to call like “Belle Époque”. The city is represented as the political and cultural center of the country. This work disputes the notion that the mentions to Rio de Janeiro in the literature of Machado are mere scenographies. The detailed study of the tales “Uns braços”, “Missa do galo”, “A cartomante”, “A causa secreta” reveals the kind of understanding that Machado de Assis developed on indeterminacy in everyday life: Rio is presented as a complex city In which the characters often encounter several lines resulting from the flow of everyday events. In Barreto's literature, the appearance / essence tension and social exclusion explain the representations of the city as a permanent estrangement from European to African culture. The study of the tales “Um e outro”, “O homem que sabia javanês”, “Cló”, “O filho de Gabriela” reveals the kind of understanding that Lima Barreto developed about the insulation of modern life: Rio is presented as a city empty of a common cultural heritage. The general considerations of this work establish that the literary images of the city of Rio de Janeiro make up a system of representations whose effect is to bring Rio de Janeiro's capital closer to European cities. Westernizing, modernizing, and liberal traits were emphasized to cover up the archaic, rural, and colonial dimensions of the country. In this way, the valorization of “europeidade” allowed the intellectual and dominant groups to identify with the European way of life. Machado de Assis and Lima Barreto, however, deconstructed these imagery through ironic and critical expressions, exposing the contradictions of urban life in Rio. Thus, the representations of Rio de Janeiro in the literature of both tended to show indetermination and estrangement as typical features of modern life in Rio.

The use of biodiesel in vehicles can significantly reduce dependence on fossil fuels and help to reduce environmental pollution. However, there are concerns about the compatibility of automotive materials in contact with biodiesel. Alloys of ferrous and non-ferrous metals that come in contact with the fuel may exhibit corrosive behavior because biodiesel, which has different chemical characteristics compared to diesel, may interact with materials in a different way. The objective of the study was to compare the corrosion behavior of SAE 8620 carbon steel; 13 Cr supermartensitic stainless steel; AA6061-T4 aluminum alloy with and without Equal-Channel Angular Pressing; copper and lead in three diesel/biodiesel binary blends (B7, B15 and B30). Mass loss tests were performed by total immersion, crevice corrosion, partial immersion and in contact with the vapor phase of each binary blends for 2160 h at 50 °C. The materials were evaluated through structural characterization, optical microscopy (OM), scanning electron microscopy (SEM) and X-ray dispersive energy (EDX), determination of metallic elements in the blends and corrosivity of the copper. The physicochemical characteristics of the mixtures were determined by oxidative stability analyzes at 110 °C, specific mass at 20 °C, kinematic viscosity at 40 °C, hydrogen and carbon nuclear magnetic resonance (1H and 13C) and ASTM color analysis. The results showed that copper and lead are materials not recommended for use in contact with biodiesel. SAE 8620 carbon steel, 13 Cr supermartensitic stainless steel and AA 6061-T4 aluminum alloy are more resistant materials in contact with biodiesel and their blends with diesel oil, which can be used, for example, as materials in the construction of transport and storage tanks.

Yacimientos Petrolíferos Fiscales (YPF) is the largest oil company in Argentina, founded in 1922 by the former President Hipólito Yrigoyen, and since then is a reference within and outside the country for being the first State oil company in the world to be vertically integrated. Also, it is currently the second largest company in the country, according to its revenue, only behind the Techint organization. In the last forty years changes in law have allowed modifications in the ownership model of this Argentine company. In 1993, YPF shift from being completely state-owned company to a public company with state control. Soon after, it was bought by the Spaniard Repsol and, in 2012, during the government of Cristina Fernández de Kirchner, was partially renationalized and it operates as a mixed company since then. Based on Economic Sociology literature, we analyze the changes in the corporate control of the company, observing the trajectory of its directors in several years, including the recent shifts conducted by Mauricio Macri's government. We specifically analyze and compare the trajectories of the directors of YPF in the years 1977, 1985, 1994, 2005, 2014 and 2016 to understand if there were changes in their trajectories that are explained and, at the same time, explain the displacements in corporate control of the company in the last 40 years. The years chosen for analysis are relevant not only for the transformations occurring within the company, but also due to the transformations occurred in the economic and political instances of the country. We base our trajectory analysis on the life histories approach (Mallimacci, 2007) and also incorporate socioeconomic variables, such as academic education (graduation and post-graduation courses and type of University), career trajectory, age and sex. We also applied the prosopographic analysis of the data gathered in the YPF 20-f form, which is the annual company reports to the Securities and Exchange Commission (SEC), in the balance sheets to the CNV (Comisión Nacional de Valores) and in specialized newspapers and magazines. Still, we will seek to use specific case studies to formalize more general ideas about the organization of YPF, both in the control of the internal environment of the company as the external one, addressing it as a field or a social space, always observing the periodic transformations as metaphors for possible changes inscribed within capitalism itself, which sometimes organizes as a more productive and, sometimes, as a more financialized system.

The present work consists of a teaching learning sequence in the theme of Acoustics, built under the theory of significant learning of David Ausubel, to assist teachers in the teaching of Physics on this topic. The proposal was implemented in a high school class of Colégio Integrado Monteiro Lobato school in the city of Itu, in the interior of São Paulo. The analysis of the data was qualitative and tried to identify if there was significant learning on the part of the students about the content of the Acoustics, so that a significantly appropriation of the concepts of acoustics was observed at the end of the work. It is believed that this material is very flexible, facilitating the application of the classroom and adapting to the reality of the teacher, since it is assembled in modules, propitiating the use in a wide variety of environments.

The research in question was conducted in the Zona da Mata Canavieira of Alagoas, Brazil, a region that is characterized by the expressive presence of sugarcane agribusiness and poverty, which is manifested in critical indicators of human and social development. The study is an analysis of the living conditions of sugarcane workers in two cities located in this territory – Branquinha and União dos Palmares – as well as of the means accessed by these men and women and their relatives to ensure family survival. The study, which is eminently qualitative, was carried out based on the bibliographical research and the accomplishment of open and semi-structured interviews with men and women of the cities mentioned above that were at the intersection of the experience as workers in sugarcane sector and the experience as beneficiaries of Bolsa Família Program. The theoretical approach that guided the research is that which deals with the precariat, this fraction of class that according to the Brazilian sociologist Ruy Braga lives squeezed between the threat of socioeconomic exclusion and the increase of the exploitation of its workforce by economic sectors; and is also, according to the British economist Guy Standing, the social segment that most suffers from the insecurity about the rights. The study showed that sugarcane workers in Branquinha and União dos Palmares oscillated between formal work and informal work, but both of which were carried out in precarious conditions. The first is related to those activities that despite be registered are extremely painful and hurtful to the physical and mental health of the worker. Some examples are sugarcane cutting, herbicide application in cane fields, and cane scrolling on slopes. The second refers to the activities done without any social protection and which are equally heavy and painful. The exploration of sand in rivers and the work in quarries are some cases. It was also seen that even the workers who were beneficiaries of a monetary transfer program such as Bolsa Família continued to accomplish precarious works and were paid well below their basic consumption needs. This leads one to believe that the program puts away the workers from the risks of complete socioeconomic exclusion, but does not give them the conditions to get rid of the need to accomplish dirty, heavy, seasonal and poorly paid jobs, such as those in the cane field. The meia sola of the title, therefore, refers to these workers, since in the region where the empirical immersion has taken place the expression has to do with precariousness, indefinition and incompleteness. The meia sola is the precarious worker of the socio-geographic space known as the Zona da Mata Canavieira of Alagoas, that is a region with huge sugar cane fields and big sugar cane mills.

This research has as general objective to analyze the trajectory and the movement of the agrarian question in the governmental agenda, from 1995 to 2006, based on the application of instruments that show the change in the priorities of this policy, specifically observing the Presidential Discourses, Decrees, Provisional Measures and Messages forwarded by the President of the Republic to the National Congress, based on a multidisciplinary view of public policies, notably the formation studies in the agenda-setting. The analysis used here, therefore, focuses on the process of changes in public policies focused on the governments FHC I and II and Lula I. So, that the objectives are achieved, this dissertation is based on the model of punctuated equilibrium (Punctuated Equilibrium Framework) Baumgartner and Jones (1993) which seeks, through temporal mapping of care indicators, analyze the rise and the changes of an issue on the government agenda over time. From the above model, will seek to clarify, explain and discuss the movement of land reform policies over twelve years of administrations. Thus, is expected to contribute to the studies in the field of public policies on the agenda of training in Brazil.

The main aim of this research is to understand how the operators deal with the variability of agricultural work in palm oil harvesting, the inherent strategies to the conditions of production and how they organize in the face of the specificities of this work, in a medium sized company in the State of Pará. To this, an adaptation had to be made in the method of ergonomic analysis of the work. The analysis contemplated the set of activities that integrate the harvest: cleaning, pruning, transportation and collection of loose fruit. Both in the look of the system as a whole and in the analysis of one by one. It was found that the distribution of the tasks is done in a fragmented way, in which each operator that was assigned to that task performs only that task. However, changes in management models are insufficient to indicate that agricultural work is influenced by Taylor/Ford models. The agricultural work of palm harvest involves a relationship in which, in part, the operator manages his own activity. So, the research suggests a management model based on the organizational specificities analyzed. It was observed the presence of little integration in the execution of the activities, of little community, although there is a good relationship between the operators. This fact is due to the tasks being organized by teams, within the parcels, under the command of a person in charge, it was verified a distribution in pairs or individual operator by planting lines, which results in monotony, reinforced by the fact of the team to work with plant of specific height. It was found that the agricultural work of the palm harvest tends to have much variability, for example, those classified as normal and predictable, such as encountering venomous animals and/or leaf thorn. We highlight problems with the use and handling of tools, which contribute to increase the efforts at work - the "handle" and the weight - require significant strategies associated with their adaptation, such as: tying alloys and filling with sand in the inner part of the aluminum cable. All these factors point to the understanding that the research extended the understanding of the "palm harvest" work and that, from this knowledge, the proposed actions generate other scientific research with intervention in the field that can bring improvements in the working conditions of these operators.

The streets historic cities are designed to support only the traffic of animal-dragged vehicles and few pedestrians. However, the heavy flow of vehicles in these cities leads to negative impacts for city logistics and for the preservation of its built heritage. These impacts are more perceived in the historical center, which is the oldest place in the cities, usually characterized by narrow streets, winding trails and, in some cases, sloping terrain, in addition to being the place where there is a predominance of commercial and administrative activities. A possible solution to minimize these impacts, particularly those related to freight transport, is the implementation of an Urban Distribution Center (UDC). However, prior to the effective implementation of a UCD, it is necessary to do a study about the conditions that may favor its use and to understand the views of stakeholders involved directly or indirectly in this process. The main objective of the study is to analyse the relevant criteria to be considered in the implementation of a CDU to supply the Brazilian historical cities, taking the example of the historic center of Ouro Preto, which is considered a reference to the other historical cities. For this, based on the perception of sustainability (economic, social and environmental), technical and historical criteria reported in the literature, is done a survey with retailers, carriers, residents, and municipal guards of Ouro Preto. Five semi-structured interviews are also carried out: three with public authorities related to freight traffic in the city, one with a manager of the commercial association and another with the head of the office of Iphan, a Federal autarchy that aims to ensure the preservation of the historical heritage of Ouro Preto. To find the relevant criteria, a descriptive analysis and a factor analysis is applied. Moreover, the qualitative analysis of interviews, and the literature review will be used to correlate the results. It is concluded that residents and municipal guards have similar point of views while retailers and carriers diverge opinions among themselves and among the other agents. The carriers have also shown against the existence of the negative impacts of transport. The variables that presented at least 75% of agreement among all the agents were: increase of the level of service; local prosperity; total investments and costs; use of technologies and vehicle size. The factors found for retailers and residents showed little correlation, reinforcing the different points of view of these agents. However, it should be noted that the most striking factor for both agents was related to the concern for the preservation of historical patrimony, by representing 14.31% of the variance in the set of all variables of the retailers and 21.12% of the common variables of the retailers; in the case of residents, this factor explained 23,38% of the all variance.

With the increase in life expectancy, there has been a raise in the use of prostheses due to the need to replace parts of the human body. To avoid tissue rejection, metal alloys from implants should be biocompatible. The Ti-6Al-4V alloy is widely used in prostheses, however, aluminum presents tissue irritation and inflammation issues and vanadium oxide is unstable, with a high probability of being cytotoxic. Thus, the search for new alternatives has reached the Ti-β alloys, whose properties are more similar to those of the human bone and its structure can present stable or metastable phases according to the quantity of the alloying elements. Unfortunately, Ti prosthesis have a high price compared to the 316L and 316L stainless steel ones, as the later do not have the biocompatibility characteristics of Ti. It seems an interesting research topic about how to use a Ti alloy coating in stainless steel for biomedical application. To be able to deposit the metal alloy, magnetron sputtering is a good choice, since this technique is largely used to obtain thin films due to the quality of the formed films, their high deposition rate, low pressure work and less intense electron bombardment of the substrate. Consequently, it has been used in the manufacture of thin films of Ti and its alloys for biomedical applications. There is no notice of another research group working in this theme. In this project, the objective is to study the influence of the surface change on the deposition of the thin films and if there is difference in the composition when performing chemical cleaning before spraying.
