The present work intends to contribute for quarrel on the agrarian reform adopting as bias the interpretation of the process of construction of the social identity generated by the adoption of new forms of sociability in the agricultural way, created for the possibility of permanence or return to the field through the implantation of rurals projects of settlements. In the field of the agricultural sociability, we look for to detect which the values gifts in the ideal and real actions of these people who pass, after conquest of a land piece, to coexist daily in one same space and presenciam difficulties and similar initial chances, even so have particular histories of life. Therefore, nor the Brazilian agricultural settlement origin and nor the profile of the seated population are similar, have distinctions not only enter the different projects of settlements, but also in the internal profile of one exactly settlement and, in this way, the perceptions that after construct the conquest of the land expresses this multiplicity of inserted social citizens in the program of agrarian reform. The methodology adopted for the understanding of the process of construction of these new identities appeared through the agricultural settlements is the concept-type of Gemeinschaft and Gesellschaft (community and society) formulated by Ferdinand Tönnies, whose complementary and contradictory nature allows in them to analyze the different forms of social organization, as the moment and the movement of the wills that characterize these two concepts central offices. The interpretation of the native categories that give sensible to the Inter life and inner life of the seated ones if of the one through the understanding of the values (dialectic component of the social nature of the human being) that, however attracts, however moves away people ones from the others. On the basis of the carried through empirical research in the project of settlement New Pontal, located in the city of Rosana, in the region of the Pontal of the Paranapanema, we could, saw study of the predominant sociabilities, to delineate the concept of agricultural society as modeller of the style of predominant life in the agricultural area (re) constructed by the agrarian reform.

Ce mémoire a l objectif de circonscrire la genèse de la méthode réflexive chez Maine de Biran. Dans ce but on délimite la période de 1794 à 1804 qui embrasse depuis les textes de jeunesse, en passant par son premier ouvrage publié L influence de l habitude sur la faculté de penser, l article Rapports de l idéologie et des mathématiques (1803) et débauche sur La décomposition de la pensée (1804), ouvrage dans lequel pour la première fois Biran définit la méthode réflexive qui inaugurerait la doctrine biranienne proprement dite. Dès lors, on porte d abord sur quelques thèmes de jeunesse, notamment le besoin de se constituer une morale sensitive et des questions concernant la notion de cause en physique ; dans la suite, on analyse le contexte historique du projet d établissement d une science de l homme et ses insuffisances accusées par Biran qui aurait dévoilé au moyen de l analyse de l habitude les deux classes de facultés ― passives et actives ― constituant l homme ; on examine finalement comment ces deux classes de faits exigent également deux méthodes distinctes, la méthode réflexive ayant lieu avec la méthode expérimentale dans la composition d une science de l homme.

The Gram-positive genus Bacillus is of great biotechnological importance. Their ability to secrete enzymes efficiently during fermentation is exploited for the production of extracellular enzymes such as penicillin G acylase (PGA). Bacillus megaterium has proven to be an excellent alternative host to Escherichia coli for heterologous gene expression. Unlike other bacilli strains, proteolytic degradation by alkaline proteases is avoided. In addition, there are no endotoxins found in the cell wall. As a result, protein yields are exceptionally high even if inexpensive substrates are used. In this work, the growth conditions of B. megaterium ATCC 14945 and its preparation for transformation by electroporation with plasmid DNA had been studied. Vegetative cells and protoplasts of B. megaterium had been used. Plasmid DNAs (pET- 32, pETduet-1, pBR322 and pHis 1522) were prepared from E. coli strains DH5α and BL21. Bacteria cultures were growth in Luria-Bertani (LB) broth, Nutrient or LBS (LB containing 0,5 M sorbitol) medium. It had been used the following Electroporation Media: 25% PEG 6000/0.1 M Sorbitol (Moro et al., 1995), 0.625 M Sacarose/1.0 mM MgCl2, pH 5.5 (Dunny et al., 1991), HEPES 10 mM, pH 7.0 (Belliveau & Trevors, 1989) and SMG (0.5 M sorbitol, 0.5 M manitol and 10% glicerol) (Xue et al., 1999). As Recovery Media after electric pulses, LB and LBSM (LB containing 0,5 M sorbitol and 0.38 M manitol) had been used. Extractions of genomic DNA of B. megaterium and plasmid DNA of E. coli had been carried through. The Colonies Forming Units method (CFU) was applied in order to analyze the B. megaterium viability before and after treatment with Electroporation Media. The biomass produced (Cx) was analyzed spectrophotometrically and by the Dry Mass method. The morphology and pureness of B. megaterium cultures had been studied by optic microscopy preparations and B. megaterium growth in liquid selective media. The best electric conditions for electroporation had been established by preliminary tests. B. megaterium transformations was performed according to protocols described by Moro et al. (1995), Dunny et al. (1991), Belliveau & Trevors (1989), Xue et al. (1999) and Romero et al. (2006). The B. megaterium growth curves in LB, Nutrient and LBS had allowed the identification of growth phases of cultures and the respective electric conditions adjustment for electroporation protocols. The cellular concentration (dry mass) found for 16 hours of culture in Nutrient, LB and LBS medium had been 1.900 g/L, 2.649 g/L and 2.320 g/L, respectively. The viable cells concentration analyses (UFC) had allowed the adjustment of plasmid DNA concentrations employed and transformation efficiencies calculation. It had been found the following cellular densities of B. megaterium grown in Nutrient, LB and LBS medium respectively after PEG/Sorbitol Electroporation Medium treatment: 8.8 x 108; 9,2 x 108 and 2.3 x 109 UFC/mL. For Sacarose/MgCl2, it had been found 2,8 x 107; 4.6 x 108 and 3.7 x 108 UFC/mL and for HEPES 5.6 x 108; 2.93 x 109 and 1.86 x 108. For SMG, it had been found 1,7 x 109; 9.4 x 109 and 1.1 x 1010 UFC/mL for Nutrient, LB and LBS medium, respectively.

From the perspective of the Semântica do Acontecimento (Semantics of the Events) and the French Discourse Analysis, which the firs theoretical field dialogues with, we have studied the way the argument ( argumentação ) for changing a transsexual s first name is built through the speaker-petitioner s own words, as well as through the argument and the designations used by the speaker-judge in order to authorize the alteration of a transsexual s first name. In the legal process, proceeded in the enunciation space of São Carlos, state of São Paulo, the petitioner transsexual Agnaldo requests the modification of his masculine first name into the feminine name Ângela. For that study we have adopted the concepts of designação (designation) reescritura (re-writing), cena enunciativa (enunciation scene), politico (politician) and argumentação (argument). Through the analysis of the corpus we could understand how the process of conception of the transsexual s own identity takes place, and how the process of social inclusion of the transsexual subject occurs (the politician being considered) for the subject, once socially excluded, is now included for the modification of the first name sentenced by the judge. There is always the liaison between the social and the politician (político), once the social recognition needs to be legally legitimated so that it can politically happen: the Constitution guarantees the political in the social perspective. Thus, in the political instance, the fragmentation takes place because the speaker-petitioner needs a place of belonging (recognition) and this place (recognizing himself as a subject being a woman ) is legitimated in the juridical discourse. Then, we understand how the process of social identification, connected with the scientific discourse, which has its own crystallized place, may contribute to the alteration of the transsexual s first name in the argumentation of the speaker-judge. Consequently, we can claim that the event and the litigation make the speaker-petitioner s speech move into the memorable (memorável) of the social environment, of the esthetical perspective and of the psychological constitution in order to change the name and that inserts him in the identity of a transsexual. And under the perspective of a liberal subject position, the speaker-judge sentenced favorably for the legitimating of the first name Ângela, who the speaker-petitioner has semantically a new body. This substitution of the official first name by the real one consolidated a new jurisprudence.

Since the 90 s, following the world productive restructuring trend, the industries of concentrate orange juice from the citrus agribusiness complex in São Paulo state refuse to be responsible for hiring people to work in the orange crop and, in this manner, new forms of recruiting workers are arising. Thus, the present work is intended for verifying if a new class of hiring named Rural Producers Partnership serves its purpose of directly hire orange pickers thus guaranteeing the formalization of the job as well as serving all work legislation required by the formalization. The partnerships were created as an alternative to rural work co-ops whose activities were interrupted by the Brazilian Department of Labor in 1999. The "gatoperativas ", as they were known, promoted a growing instability in rural work conditions when depriving workers from their major achievements, that is, their direct labor contract and labor rights. Since these activities were repressed, the partnerships have been a solution to the end of the intermediary manpower promoted by the recruitment agents. In this work it is also concluded that the partnerships are dominated by these agents, and their work relations are not organized by the producers, thus jeopardizing the work activity.

It is widely acknowledged that the indoleamine neurotransmitter serotonin (5-HT) plays a dual role in the regulation of anxiety, a role that in part depends upon neuroanatomical locus of action. Thus, whereas stimulation of 5-HT1A or 5-HT2 receptors in the limbic forebrain (amygdala, hippocampus) enhances anxiety-like responding in rodents, activation of corresponding receptor populations in the midbrain periaqueductal grey (PAG) more often than not reduces anxiety-like behavior. The present study specifically concerns the anxietymodulating influence of 5-HT2 receptors within the mouse PAG. Experiment 1 assessed the effects of intra-PAG infusions of the 5-HT2B/2C receptor agonist mCPP (0, 0.03, 0.1 or 0.3 nmol/0.1 µl) on the behavior of mice exposed to the elevated plus-maze. Experiment 2 assessed the effects of intra-PAG infusions of the preferential 5-HT2A/2C receptor antagonist ketanserin (0 or 10 nmol/0.1 µl), on the behaviour of mice exposed to the elevated plus-maze. As mCPP acts preferentially at 5-HT2B and 5-HT2C receptors, Experiment 3 investigated its effects in animals pretreated with ketanserin. The test sessions were videotaped and subsequently scored for anxiety-like behaviour (e.g. percentage of open arm entries and percentage of open arm time) as well as general locomotor activity (closed arm entries). The results of Experiment 1 showed that mCPP microinfusions (0.03 and 0.1 nmol) into the PAG of mice decreased behavioural indices of anxiety without significantly altering general activity measures. Results of experiment 2 showed that intra-PAG infusions of ketanserin (10 nmol) did not alter conventional indices of anxiety, nor locomotor activity. In Experiment 3, the anxiolytic-like profile of intra-PAG mCPP (0.03 nmol) was substantially attenuated by intra-PAG pretreatment with an intrinsically-inactive dose of the preferential 5-HT2A/2C receptor antagonist, ketanserin (10 nmol). Together, these data suggest that 5HT2C receptor populations within the midbrain PAG play an inhibitory role in plus-maze anxiety in mice.

This work reports the investigation of a series of bovine serum albumin (BSA) restricted access media columns (RAM) for on-line milk samples deproteinization using water, phosphate and acetate buffer as mobile phase. The retention factor (k) of aminoglycosides antibiotics (streptomycin, neomycin and gentamycin) on the RAM columns was evaluated using buffers and ion pair chromatography. The results showed a wide variation on aminoglicosides antibiotics retentions time; a RAM-ADS column was also investigated and the same results was observed. During the RAM columns studies, an investigation of two analytical columns, C18 and phenyl (Hyperil 15 x 0,46 cm i.d.), were performed using ion pair chromatography. Perfluorinated acids (TFA, HFBA and PFPA) were evaluated as moblile phase and the detection was accomplished by an evaporative light scattering detector (ELSD). This study allowed the development of analytical methods for quality control of gentamycin, neomycin and streptomycin in veterinary pharmaceutical formulations. The developed methods showed good selectivity, sensibility, accuracy and precision for all compounds allowing it to be successfully used to commercials phormulation. This works also presents a study for on line determination of cephalosporinic antibiotics in bovine milk by multidimentional chromatography using RAM-BSA column for sample clean-up. The chromatographic conditions optimzed for these compounds were not adequate for the MS/MS quantification due to suppression and/or enhancement of compound s ionization. Still a sensitive and enantioselective multidimensional high performance liquid chromatography (HPLC) method for determination of albendazole metabolites: albendazole sulphoxide, albendazole sulphone and albendazole 2-aminesulphone in bovine milk was development and validated at this work. The compounds, (±)-albendazole sulphoxide, albendazole sulphone and 2-aminesulphone were extracted from bovine milk using a octyl restricted access media bovine serum albumin column (C8-RAM-BSA) (5.0 x 0.46 cm i.d.) and analyzed on a chiral column containing amylose tris(3,5-dimethylphenylcarbamate) coated onto APS-Nucleosil support, as stationary phase (15.0 x 0.46 cm i.d.). The validated method showed linearity, precision, accuracy and adequate sensitivity, allowing it to be appropriate for pharmacokinetics studies and residual limits control. A matrix effect study was conducted to investigated its influence on the LC-MS method development.

There are evidences demonstrating that long-term aerobic exercises boost the plasmatic cytokines concentrations. However, there are few researches that deal with that relation in short-term and high intensity ones. This study aims at verifying the effects of strength training in circuit over the cardiorespiratory competence response and also over the plasmatic cytokines IL-6, IL-8, IL-10, IL-1β, IL-12p70 and TNF, by acute application of both tests, incremental and 35 minutes with Ventilatory Threshold (WVT) and maximum (IVO2peak) intensities. The research included 14 women, 40,23 (3,9) mean age, 164 (6,6) cm and 57,84 (7,7) kg. They did a single cycle exercise test with two stations, 30 minutes on WVT and 5 minutes on IVO2peak, just before and after strength training in circuit. The blood samples were taken at the rest time, immediately after the first and the second exercise stations for plasma cytokines analysis: interleukin 8 (IL-8), interleukin 10 (IL-10), interleukin 6 (IL-6), interleukin 12p70 (IL-12p70), interleukin 1β (IL-1 β) and tumoral necrosis factor (TNF). The cycle incremental test was conducted to verify the peak oxygen consumption (VO2peak) and the loads corresponding to the WVT and to the exhaustion. The analysis verified there are no changes in plasmatic cytokines when comparing the pre and post strength training in circuit, however, after the acute phase of the 5 minutes station in IVO2peak, there were increasing on IL- 6 during both pre [1,81 (1,36-5,05) vs. 3,09 (1,49-8,95) pg.mL-1; P=0,038] and post-training [1,62 (1,38-3,05) vs. 2,42 (1,46-5,71) pg.mL-1; P=0,021]. There were also improvement in the volunteer load [125 (100 150) vs. 150 (100-175) W; P=0,017] at the end of the intervention period. Hence, we conclude that the expression of IL-6 in plasma is protocoldependent and that the strength training in circuit does not trigger an inflammatory state, keeping the baseline concentrations of plasma cytokines unchanged. Keywords: Strength training in circuit. Cytokines. Acute phase. Ergometric cycle.

Admission at the elementary school is an important moment in the process of education. Literature has shown that to guide the family in this process, using resources from the family environment, may be fundamental in preventing school problems. In that context, this work implemented and evaluated a proposal of intervention in the form of a Programa Psicopedagógico de Orientação a Pais (PPOP) - Psychopedagogical Program of Parents Orientation -, for the parents and relatives responsible for children with learning disabilities included in the early years of elementary grades of regular public school and were attended by the itinerant service of special education, in order to provide strategies for monitoring and stimulation of their children in that stage of education. The study was developed as the ethical aspects of researches that involve human beings. The first stage of the research (Program s elaboration) tested the PPOP and the instruments in an experimental situation, whose analysis showed that the Program was able to be implemented on a larger scale and was satisfactory as the form and content, from the reports of the participants. The used instruments also were sensitive to the demand for collection. On the second stage, the implementation of the Program, participated in this research eleven parents of students who were on the early years at public elementary school and their respective children, which composed two groups experimental and control). It is relevant to mention that the content approached in the program is based on the book Como ajudar seu filho na escola ( How to help your child in school ). Besides the PPOP, the instruments used to collect data were: Home Environment Resources Scale - HERS, Roadmap, interviews with parents, Brazil s Criterion of Economic Classification, School Achievement Test, Roadmap " Situations and the Evaluation Questionnaire Course. The evaluation of the program found the effectiveness of it, from the assessment of all the steps and comparison of results of pre - and post-tests. The results allowed to assert the need for continuation of activities of that nature. The results allowed to assert the need for continuation of activities of that nature. The results showed: a) interest of mothers receive support in situations where information about the "do not know how to deal with the child" b) an increase in the repertoire of mothers of educational practices appropriate c) implementation of positive strategies on a daily basis with the children in the short term; d) the relevance of programs of this nature with parents of children with learning disability. In future studies it is suggested investment in training of ducators to use the POPP and development of strategies that extend the benefits of the program to more families.

This paper has as objective analyze REAJA Rethinking the Education of Teenagers, Young People and Adults, implanted in 1997 in the city of Vitória da Conquista BA, to identify its trajectory since its creation until nowadays. It s interesting to notice that REAJA was introduced to help the initial education of teenagers, young people and adults that didn t have the opportunity to finish their studies in childhood or teens. Trying to contextualize REAJA as a public policy, it was chosen to contextualize the education of young people and adults in Brazil, in Bahia and in the city of Vitória da Conquista, besides characterizing the studied scenery in a demographic and socioeconomic way. It was detached the legislation that guides EJA in Federal and Municipal levels. The investigation process was made by analyzes of documentation collected in the Municipal Secretary of Education in Vitória da Conquista BA, observation at schools, interviews with ex-coordinators of the Programme, SMED´s representative and with teachers that work at REAJA since it was created. Some questionnaires were applied and some data could be collected with students and teachers that work with education to young people and adults in municipal and state public net. Analyzing collected dates, it was a priority to identify positive and negative points of REAJA and the consequences of its trajectory in teaching. Many things were told about teacher s and student s expectation, besides objective and subjective questions of teaching work. Rates about enrolment, pass, recur and truancy and student s profile were collected and discussed. It was noticed that REAJA passed, during its existence for three major levels and each one has its specifications following the expectation of the leading that was in charge of SMED and coordinating the Programme.

Introduction: Several investigations have been proposing signaling and immune functions for the cytokines accomplishment of aerobic exercises. However few studies have been related the effect of the exercise resisted with cytokines. Purpose: to evaluate the effect of a resistance training in circuit about the sharp action of the resistance exercise until the exhaustion in the levels of the plasmatic cytokines IL-6, IL-8, IL-10, IL-1, TNF and IL- 12p70. Methods: 14 untrained women (39,8 ± 3,9 years), (60,6 ± 6,6 kg) and (163,6 ± 6,6 cm) accomplished two Fatigue Test (FT) in the exercises Leg Press 45º (LP) and Bench Press (BP), these tests consisted of 3 sets with 50% of 1-RM related until the exhaustion with 1 minute of interval among the sets, before and after 10 weeks of resistance training in circuit. Before and 5 minutes after FT samples of blood were obtained for analysis of the plasmatic levels of the cytokines: interleukin 8 (IL-8), interleukin 10 (IL-10), interleukin 6 (IL-6), interleukin 12p70 (IL-12p70), interleukin 1 (IL-1) and factor of necrosis tumoral (TNF). Results: The plasmatic concentration of IL-8 for the LP before and after FT in the periods pre and post-training were of (4.38 ± 2.62 and 5.73 ± 0.97 pg/ml) and (6.36 ± 1.35 and 6.47 ± 2.08 pg/ml), respectively. Moreover for the BP (3.68 ± 3.91 and 9.00 ± 2.57 pg/ml) and (5.71 ± 2.21 and 7.06 ± 2.26 pg/ml), not found significant differences among before and after FT, as well as, for pre and post-training for IL-8 in both exercises. The other cytokines did not reach the certain minimum limit of detection for the used kit. Conclusion: Resistance exercise until the exhaustion not provoke enough stress to alter the cytokinemia, before or after 10 weeks of resistance training in circuit.

No atual contexto da introdução dos transgênicos na cadeia alimentar brasileira, apresentamos os resultados de estudo que empregou o método qualitativo de grupos focais para levantar as interpretações do público em relação à informação disponível sobre essa inovação biotecnológica. A utilização desse método permitiu gerar resultados que revelaram as relações construídas pelos participantes da pesquisa entre essa modalidade da biotecnologia, as mudanças no meio ambiente e a produção de alimentos em geral. Os resultados apontam particularmente para o modo como os participantes identificaram a falta de informação compreensível, tanto na mídia de massa quanto nos rótulos de produtos, como principal fonte dos seus sentimentos de desconfiança em relação aos transgênicos.

The purpose of this research is to analyze the female presence within legal careers, how this reflects in their professionalism, and how it impacts the already established careers, taking into account the male hegemony over the work environment. The analytical framework of Sociology in Careers is used to understand this specific work environment. The scope of this research focuses on careers in magistrates and law. The former is related to the power of the Supreme Court, which is a public service career based on decision-making. The second has a more liberal background it is a private activity which depends on a client-lawyer relationship. The spatial cut is the state of São Paulo, Brazil, where the interviewees live and work. The spatial distribution focuses on analyzing the current female presence status, including the professional background of those interviewed. The central argument is that female professionals undergo a type of double barrier in their professional life. The first outlines the rules and limits of their own professional field, which are common for both men and women. These barriers are tied to the mechanisms of the profession, such as obtaining the credentials after graduating and later the process of consolidating expertise. On the other hand, female professionals might be confronted by the gender barriers. This category widens the intersection in the private world, closely connected to the female and public sphere, a standard for professionalism. The way to assume and solve the issues related to barriers that are inherent in the field or gender differ according to the position occupied by the professional, which also influences engaging and performing in a public or private enterprise. This work details how such issues impact the professional background of judges and lawyers in present-day situations.

This research shows the speech importance of the candidate to Maranhão government José Sarney and his political ability with the central power, the local social strenth, the press and a past time of glory, as he says. These actions of a political life in society do not refer to the politician s individual actions only. They also refer to the collective action in a clear relation of the politician with a global social historic context. This work gives us possibilities of a worldwide vision on a developing concept and policy application in the search of economical environment centrality, according to a general vision of this concept. Relevant arguments about this subject are presented, going from its conceptual difference and its unsustainable application in governmental policy through a long last speech in Maranhão. This investigation identifies the alliances set in a government named Maranhão Novo , the relations among public and private, political, economical and social individuais involved, joined in the practicing of squatting whose interdependent relations happen in a certain social historic moment. In the end, such actions and relations have confirmed deep changes in economics and maranhense society. Meanwhile planners and the fact that the development is feasible strictly economical, were forgotten, bringing an enormous concentration of lands. This consequent constitution of land owners, motivated by central government policy, with the national integration speech, a new age of captalism in the state began.

Educatio iesuitica in Brasilia Colonia parum scrutatum thema ab historiographia educationis quae ei exiguum spatium servat in libris Historiae Educationis. Ea res, autem, dissimilis esse deberet, maxime quia erat periodus significabilis momenti paedagogici iesuitarum in patria, quod per ducentos decem annos imperavit (1549- 1759). In hac comprobatione fultum, hoc studium agnovit et dispexit opera scientifica super scholis iesuiticis generata in disciplina post-graduationis in patria et prompta in fontibus indagationis on-line. Accessus methodologicus compositus est ex his partibus: 1) recognitio litterarum super operibus scientificis in educatione, educatione iesuitica in Brasilia Colonia, praesertim super scholis iesuiticis, sicut subsidium theoricum investigationi; 2) collectio et ordinatio materiei ex thesibus et dissertationibus ablatae in bibliothecis digitalibus; 3) resolutio effectuum secundum opera theorica historiae educationis et observationem bibliometricam. Effectus assecuti in investigatione permisserunt cognoscere modum quo thema scholae iesuiticae disseritur in thesibus et dissertationibus expositis in Disciplinis Post-Graduationis in nostra patria et opiniones super educatione iesuitica et scholis iesuiticis quas exposuerunt in eorum libris auctores experti huius materiei; faverunt, etiam, quod delineantur prospectus huius fructus scientifici, eius naturae, progressio huius thematis, auctores et institutiones qui maxime thema perscrutantur, distributio geographica huius operis, periodi cum maxima propensione ad studia thematis, inter altera. Investigatio postulat adiuvare lacunas implere in hoc scientiae spatio et roborare historiographiam educationis iesuiticae in Brasilia Colonia.

This work studies the integrated lot sizing and scheduling problem in the animal feed compound industry. The lot sizing problem in this industry consists of deciding which and how much to produce in each period, in order to minimize overtime and storage costs. The sequencing problem consists of sequencing the production lots, in order to minimize the setups (that eat into the available capacity), and to avoid the risks of residual contamination. The main difference of this problem in relation to the ones in literature is the structure of the setup times. Using a case study in a company of the sector, four approaches are proposed to model and solve the problem. The first two are based on the General Lot Sizing and Scheduling Problem (GLSP) with sequence dependent setup times. The other two approaches consist of a reformulation of the GLSP model, considering the lot sequencing as an Asymetric Travelling Salesman Problem (ATSP). Either modeling approach GLSP and ATSP is proposed for two company strategies related to the cleaning of the production line, called (1) Independent Sequences , where it is assumed that at the end of each period a complete cleaning in the production line is carried out; and (2) Dependent Sequences , where the sequence at the beginning of each period depends on the preparation state of the line in the previous period (setup carryover). The model GLSP Independent Sequences is solved by the branch-and-cut method (using the software AMPL/CPLEX), with limited computational time. To solve the model GLSP Dependent Sequences , besides the branch-and-cut method, two heuristic relax-and-fix procedures are proposed . To solve the model ATSP Independent Sequences the subtour elimination method is used. In the case of the model ATSP Dependent Sequences , as well as the subtour elimination method, the patching subtours method is used. According to experiments carried out with real data, the models and methods proposed solve the problem satisfactorily, getting better results that the company. Of the different approaches proposed, the most appropriate for the problem appears to be the reformulation ATSP with the patching method and the strategy Dependent Sequences .

The fishery of sea-bob-shrimp Xiphopenaeus kroyeri with over-trawl nets with doors used by artisanal fishery is considered an efficient method for the capture of the target specie along the Brazilian Cost. However, it presents a low selectivity and captures a high amount of the demersal and benthonic fauna that are know as accompanying fauna. Among these, is frequently found that they of the target species, the fish of the genus Stellifer. Therefore, this study, aimed to determine the bioecological characteristics of fishes of this captured in fishing held in the Armação Itapocoroy, Penha, Santa Catarina, in two ways: in the first chapter, analyzing the population structure and the reproductive aspects of the species Stellifer rastrifer, Stellifer stellifer e Stellifer brasiliensis exploited in in the period of from april/2006 to march/2007 and, in the second chapter, assessing the annual and monthly abundance distributions of the exploited Stellifer spp. populations during the years of 1996 2006.

The evolution of the world-wide production of steel in rates superior to 7% per year in the last five years, strongly driven by China, which got off 222,4 millions in 2003 for 489,0 million tons in 20071, leads to a strong increase in the demand of iron ore. Therefore, fine ore price of Carajás for Asia went out from 28,14 in 2003 for 73,20 US$ cents for unity of iron in 2007. An increase of 160%. These facts, when related to the layer exhaustion and the growing environmental pressures on Iron and Steel Plants of the whole world, have been taking to a series of studies to the use of the residues bearers from iron produced in these factories. Up to that time, there has not been consolidated any technology which is technically and economically viable for the recycling of these residues so far. The present work is about the usage of the blast furnace mud, the mill scale and the iron oxide produced in the pickling lines of Companhia Siderúrgica Nacional (CSN) in self reduction pellets shape. It starts the productions in scale laboratorial and industrial after the chemical and physical characterizations from these raw materials. As soon as the most appropriated formulation was defined, the production in experimental scale began. These tests were carried out in the residues palletizing pilot plant, developed by CSN. There were also tests of self reduction and of meltreduction. In the first one, the formation of a metal drop inside a hallow sphere was obtained, and in the second one a metal profit of 99,1%. In sequence, the alternatives were valued for internal recycling of these pellets. The use of the heat contained in the empty hot-metal torpedo-cars for self-reduction showed the most economical route. This technology of recycling was introduced industrially in CSN. Thus, in the present work of doctorate, it was developed an unpublished route for industrial recycling for iron and steel residues, which was technically and economically feasible.

The use of zeolites in the cracking of hydrocarbons is limited because the molecules higher than 0.74 nm do not diffuse in their micropores. In the other hand, molecular sieves as MCM-41, MCM-48 ou SBA-15, whose diameters are up 10 nm for the two formers and up to 30 nm for the last, have low hydrothermal stability and catalytic activity. To overcome those limitations, many studies are devoted to prepare materials, which can combine the high activity of zeolites with the better accessibility of the mesoporous materials. Among the possible methods, the synthesis of zeolites in confined spaces (nanocasting) it is seem as a powerful alternative. In this method: 1) a mesoporous or non-porous silica is impregnated with an organic compound, which act as a carbon precursor, after being carbonized; 2) the porous carbon is subsequently obtained by treatment with hydrofluoric acid or alkaline hydroxides; 3) the porous of the carbon are filled with the zeolite synthesis gel, which is formed after crystallization; 4) finally, the mold of the carbon and the template of the zeolite microstructure are eliminated by calcination. In the present work, it was used the above described method for the synthesis of nanocasting ZSM-5 zeolites using porous carbon, which were prepared from non-porous or mesoporous silica moulds (MCM-41, MCM-48 e SBA-15). The XRD of the prepared zeolites did not show diffraction peaks in the low angle region (< 5°2θ), showing that the inverse replica of the mesoporous silicas was not obtained. However, the nitrogen sorption measurements evidenced the presence of mesoporous, which resulted from the carbon nanotubes occluded during the ZSM-5 crystals formation. The mesopores observed in the Znp, nanocast from non-porous silica, were attributed to the inter-crystalline spaces generated by the agglomeration of ZSM-5 nanocrystals. The mesoporous formation in the ZSM-5 zeolites during the crystallization in a confined space (nanocating) was considerately favored by the ageing of the synthesis gel at the laboratory temperature and without stirring. That procedure allows the preparation at 180 °C of ZSM-5 zeolites with high crystallinity and in a lower time. Nevertheless, as verified by 27Al-NMR, the aluminum was incorporated partially in the zeolite microstructure, remaining as alumina in the crystal surface, which leads to a lower activity in the n-decane cracking when compared with a conventional ZSM-5 zeolite with a similar Si/Al ratio.
