It is well established in the literature that the type 2 diabetes mellitus (T2DM) may be related to physical inactivity, high fat diet, stress, weight gain, in addition to advanced age. Consequently, some studies show that the search for a better quality of life through exercise and balanced diets are increasing beyond the control of metabolic markers related to diabetes, preventing complications of the disease and excess free radicals. The aim of this study was to determine the effect of TCP® in people with T2DM, associated to the diet, in a targeted manner, evaluating: lipid profile, uric acid, fasting glucose, glycated hemoglobin and cortisol. We selected 21 women between 44-55 years old, that were divided into four groups: diabetic sedentary (SD); diabetic exercised (ED); exercised normal (EN); and normal sedentary (NS). Was used as the intervention TCP® with a frequency of 3 times/week, 1 hour per day, at 20 weeks, which was monitored throughout the study period, associated to the the diet. Blood samples were collected pre and post intervention, to perform the measurements of cholesterol, triglycerides, HDL, uric acid, glucose, cortisol, and glycated hemoglobin. Compared are the results before (b) and after (a) was used: - non-parametric Wilcoxon and Friedman; and - delta (%), which was used to determine the intra-individual variation uniformly. Results: There were no significant differences in the variables analyzed in this study, except glycated hemoglobin in the ED group, which showed a statistically significant difference (p <0.05). In intragroup comparison, when using the percentage delta, major clinical changes were obtained mainly in the exercised groups, considering that many of the values found returned to normal reference values. Final considerations: the protocol TCP® method associated with the diet was effective in improving the parameters analyzed evidence, making important clinical changes in diabetics who exercised. Examples of this were the clinical changes, with statistical difference in plasma levels of glycated hemoglobin in the ED, important for the prevention of complications of the disease factor.

Ovariectomy in animals (surgical removal of ovaries) is a model used to mimic the menopause in women. The ovarian hormone deficiency alters the lipid profile, increases inflammation and the risk of type 2 diabetes mellitus, sarcopenia, osteopenia, obesity and cardiovascular diseases. Resistance training (RT) has been used as a non-pharmacological tool to prevent or reverse the postmenopausal effects. However, there are few studies evaluating the ovariectomy (Ovx) and RT effects on the morphology and angiogenesis of visceral adipose tissue (VAT). Thus, the aim of this study was to investigate the Ovx and RT influence at the size and adipocytes number, gene expression and VEGF-A protein levels and microvessel density in VAT of rats. Adult Sprague-Dawley rats were divided into four groups (n=6 per group): Sham-operated sedentary (Sham-Sed), ovariectomized sedentary (Sed-Ovx), Sham-operated resistance training (Sham-Tr) and ovariectomized resistance training (Ovx- Tr). During the resistance training period, the animals climbed a 1.1m vertical ladder with weights attached to their tails, which were progressively increased; the sessions were performed three times a week, with 4-9 climbs and 8-12 dynamic movements per climb with intervals of 2 minutes between climbs. Histological analysis was performed to analyze vascular micro density and morphology of VAT; gene expression and VEGF-A protein levels were analyzed by real-time PCR and ELISA, respectively. Ovx resulted in higher body weight, adipocyte hypertrophy, decreased both VEGF-A mRNA and protein and VEGF-R2 mRNA expression, and decreased the micro vascular density in the VAT of sedentary rats. However, RT was not able to prevent any changes induced by ovariectomy. The data indicated that Ovx impaired the morphology and angiogenesis of rats VAT and that RT protocol adopted did not prevent these changes. We suggest future studies performing adaptations in this resistance training program, associated or not to hypocaloric diet and treatment with estradiol.

The First Command of the Capital (PCC), approached here as a Movement, appeared in São Paulo s prisons in the early 1990s and today is present in the majority of penal institutions and urban areas within the State of São Paulo. This approach taken here has two important implications for the thesis. Firstly, it demands reflection on an ethnography in motion. Secondly, instead of conduce to the exposure of forms, it required to make the description of the PCC-making. Thus, this thesis concerns the modes of doing PCC and ethnography. Methods therefore. The seemingly abstract notions that gave name to the parts of this thesis (motion, idea and situation), associated with others that were called to make the descriptions, they all show a (mobile) way of existing and seeing this existence which can be called PCC. Inspired by this practice of knowledge, this thesis presents the description (1) of the movement, composed of countless movements that, refusing spatial demarcations, lead to a critique of the notion of territory; (2) of the ideas, which, without defined origin and predictable or definitive end, bring into question the ways in which the concept of hierarchy are worked in the social sciences; (3) of the situations, which displace the notion of law to not legalistic bases. In short, this thesis presents some characteristics of PCC that allow to replace some key concepts to anthropology. These displacements give the title to this thesis: before naming what will be described, this title indicates what will be challenged by my description about the PCC.

The dissertation deals with how the Asurini from the Xingu conceive and produce their children and how their children portray themselves and the reality they see. The images of the fieldwork brought to the theoretical field, reveal the relationship between spaces, knowledge and skills, managed by men and women in manufacturing consanguineous bodies, prepared by and for the shamanism. It also approaches the matter of mobility of the groups of children in the space delimited from the ukara (yard), whitch serves as a cutting to the sociality, giving to each child the possibility of activate alternatively a net of relationships with people of its age group and/or genre, defined from the matrilineal or patrilineal branch. The remaining possible relationships out side of the ukara exist in the context of affinity and are built from the oppositions and contradictions. The debate about the importance of the kwasiat knowledge, term which designates as much the geometrical drawings as the writing, opens and closes the work, characterizing at the same time a representative visual code, a prophylactically art and a Assurini way of comprehension of the writing, which determines the place of the school education and highlights the complexity of the notion of “bilingualism and interculturalism” in this field.

This essay seeks to analyse the meanings of appreciation of the caipira culture, present at five editions of the National Meeting of Guitarists - conceived and organized by the Rural Landless Workers Movement [MST-SP], between the years 2003 and 2009 -, and its implications for the organizational process of the settlers of the Northeast of the State of São Paulo. Our main hypothesis points out that the appreciation of the caipira culture was configured as an organizational strategy of MST, directly related with the rooting of its settlers in a period in which the Movement sought to establish itself in the region of Ribeirão Preto a town that boasts the title of the national capital of agribusiness. This process occurred in reaction to the social derogatory imagery about the caipira, hegemonic during the last century, and that under the dual thinking, started to be considered the typical representative of the Brazilian archaic rural past , this is, the antithesis of the modernization process of the country. The theoretical framework of this research is critical to this school of thought - held by the Paulista Sociological School - which was responsible for interpreting the caipira and its culture from the historical-dialectical movement manifested, specifically, in the type of capitalist development adopted in Brazil. By observing the recent movements of appreciation of caipira culture, one of which we consider to be the empirical field of this work, we reaffirm the relevance of this debate. The method of observation and data collection is based on two sources: a documental one, which refers to the interviews carried on the Meetings of Guitarists aiming to build part of the event memory; and another one, result of our fieldwork done in a settlement of the region in which we conducted semi-structured interviews with settlers who actively participated in the design and construction of the National Meeting of Guitarists. We believe that this research brought important elements to think critically about the caipira culture not only as the survival of a past to be appreciated, but as part of a concrete historical process which, in the present, acts in a contradictory reality of agrarian reform settlements.

The First Republic (1889-1930) is known for the existence of federalism, the domain of the state Republican Parties, and the economy focused on the production of coffee, the major export of the country until the Great Depression of 1929, which changed the dynamics the world economy. Policy frameworks in the last decade of the regime society, 1920's, there were major social disruption discharging in an untenable situation, resulting in a transformation of the political system after the victory of Julio Prestes. His candidacy, chosen by Washington Luís, and subsequently his election victory, to the disgust of mineira policy elite, gaucha and state oppositions. This disagreement was crucial to system fragmentation point, generating a new political organization in Brazil, entirely different from the republican period, based on an administrative centralization around the Union Therefore, this present study aims to study the role, mainly actors political São Paulo, the events related to the 1930 Revolution, and how it behaved before this milestone in Brazilian history. It seeks to understand for what reason federalism that benefited the State of São Paulo and his collapse affected his independence from other states achieved by the end of the Empire and Republic Day. Related to this central problem, three questions are appended: What is the reason Washington Luís have chosen a paulista candidate for his succession? He was acting as institutional norms of the period or your choice was precipitated, causing the acceleration of the decline of the system process? How to react to the political elite of São Paulo with this choice, both before and after the revolution? For this, the method of situational analysis is used. Through modeling of Brazilian society, observes the actions of individual actors in this moment of institutional crisis, to finally understand the motivations that contributed to the dissolution of the First Republic.

We present the mixture model with first order dependence, MMM(1). This model corresponds to a redefinition of the hidden Markov model (HMM) where a non observable variable is used to control the mixture. The usual mixture model is a particular case of the MMM(1). The proposed redefinition makes easier the application of usual estimation tools as the EM algorithm. We present the maximum likelihood and Bayesian estimators for the normal and binomial cases of the MMM(1) and usual mixture models. Simulation studies show the functionality of the proposed models and their estimators. And finally we present an application to a real data set for the binomial case.

The first part of this work involved the synthesis of chalcone derivatives towards the development of inhibitors of the enzyme cruzain from Trypanosoma cruzi. Different green chemistry approaches were employed to functionalize chalcones as the use of alternative solvents as well as source of energy. A new Suzuki cross-coupling methodology for synthesis of functionalized chalcones was developed, employing PEG-400 as solvent under microwave irradiation. The use of organocatalysis in the 1,4-addition of α,α-dicyanoolefins to α,β- unsaturated carbonyl system provided products with good yields and excellent enantiomeric excess. It was also developed a new synthetic route for the synthesis of γ-butenolides from chalcones. The key step was accomplished using montmorillonite K10 clay as catalyst and ethanol as solvent...

In the late nineteenth century there was formed the Quilombo Saracura in Bexiga. Later there was an intense process of territorial / racial redefinition which promoted the shift of the black downtown area of São Paulo to Bexiga. This stream was concomitant with the arrival of Italian immigrants in the neighborhood. The black population lives in this area until the present day, but different medias represents the Bexiga as a typically Italian region in Sao Paulo, erasing the contributions from other social groups. Given the process of racialization and asymmetrical relations, this research presents as general purpose to investigate how the black culture in the neighborhood are interpreted by self-declared black subjects. For this, was researched a samba school, a Candomblé and a black pastoral that marks this urban context. Besides the direct observation, were realized interviews based in the history of life. Given that the culture undergoes transformations and that identity is not fixed, was analysed the translation, ressignification and/or tensions between different cultures and identities. The research is based on theorists of Cultural Studies, especially authors who works from a Postcolonial Perspective.

The objective of this work was to evaluate the teaching resource WebQuest and the topic of green nanotechnology in order to promote scientific and technological literacy in basic education. Specifically, we tried to identify the perceptions of students of nanotechnology; analyze the relationships among science, technology, environment and society (STES) established by the students when researching into nanotechnology; verify the learning of school content of chemistry by the students when it comes to nanocapsules of controlled release; and finally, check the acceptance of the WebQuest proposal by the students. The results showed that nanotechnology and the WebQuest resource are of great potential to promote scientific literacy in basic education. The students were guided to reflect on the relationships among science, technology, environment and society (STES); thus, developing the critical thought necessary to good citizenship. The approach also showed it is possible to relate basic school content of chemistry (pH, solubility, chemical equilibrium, equilibrium shift, etc.) to contents regarding nanotechnology, even though the students showed certain difficulty learning the school contents in order to understand the nanocapsules of controlled release. WebQuest, a teaching resource already successful for oriented online research activities, was also shown to be a very adequate tool to promote scientific literacy, as long as the task is oriented for such purpose.

In this dissertation the mechanical properties of short and long term of PEEK/nHA nanocomposites with potential application as orthopedic implants were studied. The nanohydroxyapatite (nHA) was surface-treated with the coupling agent aminoethylaminopropyltrimethoxysilane (AEAPTS). After treatment, the nanoparticles were mixed with the polymeric matrix of poly (ether ether ketone) (PEEK) in a twin screw extruder. Subsequently specimens of the nanocomposite were injection molded. These specimens were subjected to mechanical tests to have their properties compared with the pure polymer and the nanocomposite with the pure nHA. First, tensile tests were conducted; through these analyses, it was found the stress and strain at break increased. The presence of the silane increased the fatigue life of the nanocomposite suggesting a higher interaction between the matrix and the nanofiller. The impact tests confirmed the higher resistance of the sample with silanized nHA. It was concluded that the silanization of the nHA was effective, strengthening the interface PEEK/nHA; however, silane molecules also plastified the polymer matrix. The injected test specimens were subjected to annealing. The objective was to determine how the increase in crystallinity induced by annealing influenced the mechanical properties. After the annealing, the presence of the silane did not cause significant changes in the mechanical behavior of the material. Analysis of scanning electron microscopy (SEM) and dynamic mechanical analysis (DMA) were done in order to characterize the structure of the nanocomposites. The morphology observed in the micrographs was correlated with the dynamic mechanical properties. It was concluded that the nanocomposite with silanized nHA besides having elastic modulus behavior similar to natural bone, also had a more homogeneous structure than the nanocomposite with pure nHA.

Amorphous Iron-based alloys can be processed in such a way that, if well designed, it can ensure an attractive combination of mechanical and electrochemical properties, particularly in petrochemical industries where high level of wear and corrosion resistance is required. The success in obtaining such properties is dependent on the design quality, which is dependent on the level of technical-scientific knowledge of the area. Thus, in the present work, we attempted to conciliate a scientific study and a practical application. The work was divided into three parts, the first one is: the evaluation of corrosion resistance of amorphous alloys in the form of ribbons prepared by melt spinning from pure elements; the second one is: the characterization and evaluation of electrochemical properties of amorphous ribbons made of superduplex commercial alloy modified with boron (SDM) in front of the crystallization level. And, in the last part, a more practical application was developed, where in partnership with Hydro-Québec in Canada, the HVOF thermal spray process in substrate pipes used in drilling wells by Petrobrás Company was performed. Powders from spray forming and high energy ball milling as ZOZ mill type were produced, the coatings showed different levels of crystallization. In this way it was possible to conciliate the results with those obtained from previous steps. The characterizations were performed by several techniques such as XRD, DSC, SEM, TEM, EDS, MO, analysis of hardness and porosity. The corrosion resistance properties were evaluated from the polarization curves for high salt media (35 g/L NaCl) and the coatings were evaluated by abrasive wear tests on dry sand/rubber wheel. The results indicated a large capacity of alloy SDM to achieve a combination of properties such as corrosion and wear resistance.

To fulfill its purpose, we will get this work started from the present conditions of the national videogame production. That is a rising industry with increasing attention from the national state because of its potential in many aspects, such as the economical, educational and artistic ones. At the same time, the industrial polices are restricted and discontinuous and the development experiences take place with a great deal of inequality, and the production is concentrated mostly in some specific locations, without a large development tradition. Because of that, we have chosen to carry out case studies about videogames produced with support resources from state agencies industrial polices. Thus, we search to analyze the effects of these initiatives in specific videogames, on their inherent content and form as well as aspects such as their team design, work method, their relationship with supporters and the task of videogame advertising and distribution. We search, in this sense, to understand how state oriented industrial policy can be seized, what are the difficulties faced by producers, the result oriented most successful ways of conduct and the mistakes that were made along the way. Such a manner, we propose to indicate some possible coordinates and prospects for the foreseeable future of the national videogame production.

The present work analyses the public policies related to confronting violence against women in São Carlos city, between 2008 and 2012, from the field research carried out along with various bodies responsible for their implementation in a local sphere, regardless of being associated with the federal, state or municipal sphere of the government. The bodies are: Center of Reference for women (CRM), Women Police Station (DDM), public defender, Care Program for Women Victims of Sexual Violence (PAVAS) and Laboratory of Analysis and Prevention of Violence (LAPREV). From the documents and interviews carried out with representatives from two of these bodies, the research tried to respond: a) if the actions taken by them are based on the National Policy for Confronting the Violence against Women and Maria da Penha Law; b) which means, strategies and difficulties were found for taking such actions; and c) if there is an interconnected network in federal and intersectoral terms for the integral assistance to women victims of violence in São Carlos. The study attempts to rescue the history and reflection about the appearance of human rights, as well as the struggle of women s movements to recognize and guarantee their interests, freedom and rights, with an approach based on feminism, gender issues and the recognition of the violence against women as a public problem, which resulted in the development of the public policies for women both in international and national sphere. It was concluded that there has been a recent empowerment of these policies in Brazil through the development of law and institutional tools that broadened and directed the protective measures for women. In the case of São Carlos city, they also contributed to the local management course and initiatives, associated with the commitment to the cause, and enabled the creation of a service network integrated with all the bodies and services, although its growth, allied to a civil education of respect to women, consists of challenges to be faced in the management and implementation of more efficient policies to combat violence against women in the city.

The electronic gaming industry has recently witnessed an exponential growth in terms of titles and overall complexity of the games. This growth is responsible for many advances in computational technologies. But it also revealed problems related to the development process. It is very common that game projects exceed budget and schedule, not to mention the high number of bugs delivered to the final consumer. Current tools that support the development of games, such as game engines, allow great flexibility and artistic freedom, but require professionals with a high degree of technological knowledge, which means that a high financial investment is often needed. To help solving these problems, the literature suggests the use of Model-Driven Development (MDD). The increased abstraction level made possible through MDD can lead to higher reuse levels, and the automation achieved by code generation helps to reduce development time. But for automation, the developer often has to pay the price of reduced flexibility since the MDD exists a lack of flexibility in designs, but with manual code that can be overcome. Given these challenges, it is proposed an approach for game development that targets models to offer efficiency but without losing the flexibility in projects. This goal can be achieved through the integration of multiple DSLs with handwritten code, with the help of design patterns. To evaluate this approach, it was developed a tool capable of assisting the development of games following the concepts of MDD, which was subsequently subjected to experiments to validate its effectiveness. According to the experimental analysis, it was possible to observe that the proposed approach can provide the desired efficiency and flexibility in game development. It was also noted that due to the automation offered by code generators, inexperienced developers could create their projects with greater ease. However the study indicates that abstraction offered by MDD hinders the learning of the technology used.

Ce travail vise à analyser la constitution du sujet moderne dans la pensée de Michel Foucault. Pour ce faire, nous prétendons révéler l‟archéologie à l‟oeuvre dans la généalogie. Cela s‟observe particulièrement, c‟est ce que nous nous proposons d‟étudier, dans la présence de l‟épistémè (concept largement discuté dans l‟oeuvre Les mots et les choses) dans les mécanismes de pouvoir présents durant le classicisme et la modernité. Ainsi, nous visons à observer la relation entre « l‟ère de la représentation », historiquement attribuée à la période classique des XVIIe et XVIIIe siècles, et « l‟ère de l‟histoire » contenue entre les XIXe et XXe siècles, appelée également modernité par Foucault, et leurs savoirs et pouvoirs contemporains respectifs. Dans un premier temps, nous vérifions la relation entre l‟épistémè classique et les autres savoirs discutés par le philosophe pendant le classicisme de la période archéologique. Ensuite, nous vérifions la relation qui se joue entre pouvoir et savoir durant la période citée précédemment pour nous approcher de l‟archéologie de la généalogie. Dans un second temps, notre recherche, procédant analogiquement, se consacre à l‟analyse de la modernité. Cela favorise le rapprochement entre épistémè d‟une part et les autres savoirs discutés durant la période archéologique d‟autre part, de même que cela induit la vérification de la relation entre archéologie et généalogie dans la constitution du sujet moderne.

In this text we examined the actions of the Brazilian government, in its different dimensions, compared to the social demands and academic debates on the ethnic-racial relations. Our thesis is that race and affirmative action with racial criteria categories intend to demarcate the nation and an important frontier in Brazilian scholarship on ethnic-racial relations, unraveling the processes of racialization present in the country's history. They intend to destabilize the nation, disarticulate and implode some of the pillars of the national discourse constructed throughout the twentieth century, namely: the Brazilian people - condensed in the discourse of mixed nationality; the myth of harmonious coexistence among ethnic and racial groups; and the notion that Brazilian racism would be harmless or residual. The central objective that guided this study was to understand the conceptual and ideological ruptures and transformations within the national-state in the course of antiracist struggles and achievements of rights. More specifically, we had the following objectives: to observe the concepts that guided the Brazilian intellectual production with regard to race relations in different historical moments; rescue the major elements present in the struggles of the Brazilian black movement in the highlighted period; understand which dialogues and which deadlocks present in the relationship between the state, the black movement and academia. In temporal terms rescued, first, some (social, political and theoretical) elements occurring in Brazil and elsewhere throughout the nineteenth and twentieth centuries and that assist us in understanding the current situation. Subsequently, we focus on the period stretching from the 1980s to the present day, when it opened a new scenario to think Brazilian racism due to reformatting of the Black Movement, the adoption of the Federal Constitution of 1988 and the emergence of affirmative action. The analysis is diachronic, since it prioritizes the processes, but also focuses attention on critical events, such as the Afonso Arinos Law; the Federal Constitution of 1988; the Durban Conference (2001); the National Curriculum Guidelines for the Education of Ethnic-Racial Relations and the Education of African-Brazilian and African History and Culture; decisions of the Supreme Court with respect to coordinates (2012), among others.

Fossil Fuels have been used for more than a century as energy sources and vectors. Albeit their high energy densities and easy transport and containment, their availability is limited and they are notorious local pollution and global warming drivers, delivering no sustainability. Hydrogen Fuel Cells are a promising alternative for its substitution. However, more technological development is necessary for the production, conversion and especially for the storage of Hydrogen. Several materials absorb hydrogen, storing it through physical or chemical bonds. Innumerous research efforts have been conducted for the discovery of new such materials and for the enhancement of their hydrogen storage properties. The present work attempted to quantify these efforts through Scientometrics, revealing their time evolution, main material classes and work strategies of countries and institutions. Scientific Publications in the field were collected and processed by Text Mining associated with Bibliometrics. Technological Indicators were elaborated and analyzed with Technological Forecasting and Competitive Intelligence tools. We mapped the time evolution of the publications in the field, in the Materials Classes and in the main countries, the concentration of efforts per Country, and the main Institutions per Materials Class. From 2010 we observed a reduction in the number of Publications, related to the frustration of the exaggerated expectancies generated in the previous decade s Hydrogen Hype, associated with the transfer of efforts to Battery based Electrical and Hybrid Vehicles. Among the Materials classes, Metal Organic Frameworks stood out for their highest number of publications and growth, although its research only recently gained momentum. The main Countries were split into those that showed a recent growth in the number of publications and those that stagnated after 2010. From the general analysis of the field and the strategies of the main countries and research institutions, we expect to support decision making in the field, concerning amongst others: the allocation of human and monetary resources, effort directing, partnership formation and benchmarking.

We aim with this dissertation, conduct an analysis of discursive pronouncements tenure of the presidents of the Republic, in order to ascertain the effects of meaning of the word "people" produced in these speeches, along with the images of themselves that every president conveys, in building "us "political as well as the image of the auditorium of these pronouncements. For this, we take as our research corpus pronouncements tenure of presidents Tancredo Neves (1985), José Sarney (1985), Fernando Collor de Melo (1990), Franco (1992), Fernando Henrique Cardoso (1994, 1999), Luiz Inácio Lula da Silva (2003, 2007) and Dilma Rousseff (2011). For this, we take as our research corpus pronouncements tenure of presidents Tancredo Neves (1985), José Sarney (1985), Fernando Collor de Melo (1990), Franco (1992), Fernando Henrique Cardoso (1994, 1999), Luiz Inácio Lula da Silva (2003, 2007) and Dilma Rousseff (2011). We promote a brief characterization of the political discourse, we make a theoretical route, introducing some important caveats to our analysis of its operation. Thus, we try to show how it gives the relationship of what is meant by politics and what became known as political discourse. A third point to be addressed is the formation of identities and the legitimacy and political discourse in an attempt to better understand the subject that gives the president the power to say. Then, by considering the pronouncement presidential inauguration ritual that requires a specific discourse genre, we briefly discuss about some considerations about the discourse genre, topic that is discussed further in the discussion of specific genres and ritual part, we make a parallel between the ritual inauguration and gender pronouncement of possession. To help us meet our analyzes, we present a discussion of the notion of Production Conditions of discourse in order to show how this concept becomes productive for understanding the production of meanings in the discourse. Having analyzed the senses of people present in the above pronouncements of possession, promote, in the third chapter, an analysis of how the image is constructed in these presidential speeches, with reference to the meanings produced for "people" in the previous chapter, ie, how the subjects presidents create an image of themselves in relation to the senses of the people present in his speech. At the conclusion of this work, one can see that the sense of "people" acquires a watery consistency, slipping widely not only from a speech to another, as even within a single discourse, producing effects of various senses, which corroborates the assertion that these senses, this division does not watertight, but acquires new and constantly different contours.

This study aimed to optimize the digestion of solid samples using microwave oven with closed flasks and understand the physicochemical parameters involved in this process. The development of this study was based on EN71 / 3 and CPSC-CH_E1001-08 standards. We performed a fractional factorial design (screening) to identify the significant variables for the process. The variables studied were volume of HNO3, heating program conditions, the addition of analytes and residual. The following responses were used to identify the most important variables: acidity of digested (%), the presence of the remaining solids digestion process (%), and recovery of previously added analytes (Pb and Cr). After identification of significant variables it was possible to set some parameters of the system and a new full factorial design 2³ (Design 1) was performed for 10 different types of samples, and the variables studied addition of H2O2, addition of analytes and sequential digestion. The responses observed were previously added recoveries of analytes (Ba, Cd, Cr, Hg, and Pb) and presence of the remaining solids digestion process (%). Data of Desing 1 was evaluated using multivariate analysis in order to detect clusters and trends among the strains. A new full factorial design 2³ (Design 2) was performed with selected samples and the following variables investigated: addition of H2O2, addition of analytes and volume of HNO3. The responses observed for Design 2 were recoveries of analytes previously added (Ba, Cd, Cr, Hg, and Pb), and comparison between the two systems digestion microwave assisted samples. The conclusions are that it is not possible to digest samples with different physicochemical characteristics in the same batch, the proposed system is not recommended for the determination of Cd and Hg and the proposed system can be used in order to perform a screening in samples.
