This dissertation is based the relationship between Phenomenology and Metaphysics, one of the pillars of contemporary French Philosophy. If, in that context, there seems to be a consensus according to which the metaphysical is originary, we, on the other hand, aim at investigating its place and its origins. This work focuses on one of the aspects over which that relationship has developed, and which, at the same time, characterize one novelty of contemporary Philosophy, namely, the concern with language and with writing. When the phenomenological discourse unveiled what it first denied, the Being, when it neutralized itself in this incapability of expression, it brought the metaphysical, which thereafter needed to be seen as originary. What characterizes the metaphysical in discourse is, thus, a rational cohesion without a concept, that is, the absence of abstract and objective categories and of pure meanings given a priori, for a thought which could possibly be prior to language. With this rearrangement of the metaphysical concerning language, and taking it as a Philosophical theme, we return to the origins and to the inauguration of Philosophy. Finally, we analyze this surpassing of Phenomenology through the return to language phenomenon, which meant having another encounter with Philosophy after Phenomenology. This re-visitation meant the narrative of a new beginning. As we proceeded in this process, the importance of language for the whole ontological project of Merleau-Ponty became more and more clear, especially concerning the initial moments of a Phenomenology of perception, when it was not in the center of our analysis, and when it was not discussed. This silence was revealing to us.

The great majority of Brazilian cities use Planta de Valores Genéricos (Generic Values Map) to make their sites (lands) valuable. It is really important that all the unitary values presented in this plant, must be in accordance with the values used in the real estate market. This work (paper) has the purposes of explore and evaluate the Planta de Valores Genéricos (Generic Values Map) in the city of Lins and the technical procedures that were used for its conception. It is broached too the potential use of other data sources and methodologies to make values homogeneous, besides the one traditionally used, which comprehends offers made in newspaper’s classified sections, in the real estate market and the use of the traditional methodology to make values homogeneous. It’s presented some aspects that lead to the record current state and to the evaluation system current state, and some damages originated by its delay.

The production sequencing is an area of great importance in Production Planning and Control, because businesses are looking for higher productivity and competitivity, in order to meet the demands and expectations of their respective markets. To hasten and to be flexible the production processes through efficient production sequencing contributes to satisfy this market. Simulation technologies have been used to model, plan and control complex manufacturing systems. To accomplish the production sequencing in these environments, with the support of the simulation, it is necessary to reduce the total amount of simulated scenarios and evaluate the simulation results. Artificial Intelligence techniques can help these tasks. This work has proposed an intelligent system for production sequencing, supported by simulation techniques and Artificial Intelligence. This goal is based on ideas already studied in the research group of the Computer Science Department at Federal University of São Carlos. The system was implanted and many tests were accomplished. First, some sequences are selected with products that are able to enter the production system. Then the sequences are simulated and, forward, put on action an estimate process that classifies them. To run the tests was considered a specific Flexible Manufacturing System (FMS).

We study if a time-dependent system is either dynamically stable or unstable, i.e., if the expected value of a positive and discrete observable is a bounded function of time or not. Initially we consider topological properties of the orbits of the states of the system and how these properties are related to dynamical stability. In the case of periodic time dependence, we present a formula that allows one to decide about stability from the behavior of the matrix elements of the resolvent associated with the Floquet operator. Finally, we give an example of Floquet operator with purely point spectrum and exponentially decaying eigenfunctions and dynamical instability.

This work is a critical analysis of Walter Freeman´s neurodynamic model in several aspects, especially the consciousness as an order parameter that constraints brain dynamics. According to our research, this proposal is not only based in empirical data, but also in ideas as: 1) mathematical metaphor valorization to explain the nature and man; 2) the consciousness as an integrative rational action that limits and selects local fluctuations. We found some gaps in the model, as the author himself admits, and also other interpretations for some empirical results. Therefore, the meaning of neurodynamic patterns found by Freeman remains open. His emergentism is defined by dualism and reductionism denial, and is based in circular causality between whole and parts. Motor cause (and material, we suppose) from the base to the top, and formal and final cause from top to base. It seems to be a pragmatic solution for the mind-brain problem, in order to make possible a wider scientific acceptance of mind effects on the body, contributing to a paradigm change in neuroscience. For Eliasmith, the role of non-linear dynamics would be description, discussion and analysis of complex cognitive systems, as brain. The interpretation of information and dynamic patterns found, however, is not evident nor consensual. This work corroborates such conclusions in particular case of Walter Freeman's model, still highlighting a non scientific role for his work, in the sense of valuing the systemic effects of consciouseness on the body.

The present work examine, historically, all the Brazilian period republican observing practical of advantages politics that had been present in the sphere politic to analyze the performance of the gospel members of the house legislative of São Paulo. The choice of the members with religious filiation was given in reason of the expressive increase of evangelicals, temples and visibility of the gospels. The objective of the work is to verify where measured the clientelism it is present in the analyzed group and of that forms this practical if differentiates of the definite clientelist relation for specific literature. For in such a way, the Projects of Law had been analyzed presented by the group during two mandates, understood between the years of 1999 and 2006, taking in consideration categories defined for the authoress of the work. The study it demonstrates that, even so the clientelism is practical current between these politicians, it operates in the direction of attainment of recognition for the religious ones as well as, for the on entities to the denominations of which there are members. And, operates not more in the geographic level, or either, of electoral redoubts as the traditional clientelism when benefiting cities or regions as a whole. This is clearly when comparing the result of the clientelist exchange in the form of fidelization of the vote that is, basically, the electoral success.

The Cravo lime species (C. limonia) acts as the grafting host, mostly used in the Brazilian citriculture and because of its precocious productivity, besides its good adaptation to most common soils, permitting for an optimum harvest. With the aim to contribute to the chemical knowledge of these graftings and to better understand its mechanisms, a phytochemical study of the rootstock from C. sinensis onto C. limonia were carried out. Earlier studies indicated the presence of a remarkable amount of prenylated compounds in the lower part of the C. sinensis graft, onto the C. limonia, while at the same time in the upper part these compounds was found in a very small amounts, rising to the assumption that these compounds could have been translocated from the host to the introduced graft species. In this way, biosynthetical studies of prenylated coumarines were also carried out aiming to evaluate the activity of the prenyltransferase enzyme, responsible by the incorporation of the isoprene units in these compounds. With the objective to advance our knowledge and chemical profile of the Rutaceae family, in which the Citrus genus is inserted. This study also describes the phytochemical and phytosystematics of the Nycticalanthus specious species pertaining to the same family. In the study of the rootstock, several different chromatographic methods were applied permitting to identify nine substances one of them being an unpublished flavanone. From the Nycticalanthus speciuous, eleven compounds were isolated as well as an indolopiridoquinazolic alkaloid and also three limonoids previously unheard of. The isolated compounds from the rootstock were assayed against the fungus Guignardia citricarpa, responsible for the black stains in Citrus species , with the objective to find a possible antifungus for this disease. Two coumarines showed premissory inhibitory activities. The biosynthetical study carried out with the prenyltransferase enzyme DMAPP, Umbelliferone and Herniarin showed that the translocation of the pyranocoumarine Xanthylentin should have happened. Seen in the different parts of the grafting of C. sinensis onto the C. limonia the enzyme were active only in the roots and with this observation, it appears that the coumarine is being metabolized in the lower part and translocated to the upper parts of the graft.

In this work a study of proteins Jacalin and Concanavalin A, belonging to the class of lectins, and the interaction with different carbohydrates was accomplished through Quartz Crystal Microbalance (QCM). The lectins were immobilized by self-assembly monolayer by means three methods. In two of them were used the cystamine and glutaraldehyde and the protein immobilized in a single layer or multilayer. In the third method, a solution of thiols, 11-mercaptoundecanoic acid and 2-mercaptoethanol, in a proportion of 1:10, and the reagents reagents Nethyl- N-(dimethylaminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS) were used to formed a intermediated reactive to binding a protein of interest. Significant differences were not observed among the methods, being opted for the lectins immobilization in a single layer using cystamine and glutaraldehyde due to the simple preparation and low consumption of reagents. The formation of self-assembly monolayer formation was studied using the Electroacoustic Admittance, QCM and a flow injection system coupled to QCM. In all studies a cystamine concentration of 15 mmol. L-1 produced the highest frequency variation and therefore the largest observed mass deposition on the gold surface with good repetitivity. However, it was observed a strong interaction between the free cystamine and to that was binding to the gold surface forming a monolayer, but this interaction was not specific. The flow injection system coupled to the QCM technique was also used to study the interaction between the lectin-carbohydrate and lectin-glicoconjugate. This study allows determining that the variation of the quartz crystal frequency was the same magnitude that observed for a system when using a QCM technique. The Langmuir adsorption isotherm was used to calculate the values of the apparent affinity constant for the lectins with different ligands. The apparent affinity constant was 1.4x105 M-1, 9.4x103 M-1 and 5.6x102 M-1 for Jacalin- Fetuin, Jacalin-Galactose and ConA-Maltose interactions respectively. The determinations of the apparent affinity constants using QCM, demonstrated the viability of the technique in the study of molecular interactions.

The objective in this study was to estimate genetic parameters for the traits days to calving (DC), days to first calving (DFC) and gestation length (GL), associated with reproductive performance of females, as well as to evaluate the relationships of DC and DFC with scrotal circumference at 12 months of age (SC12) and body weights at 12 months of age (W12), at calving (WC), at first calving (WFC), at beginning of the breeding season (WBS) and at beginning of the first breeding season (WFBS), and of GL with weight at birth (BW) and W12. Analyses were done using animal models and the derivative free restricted maximum likelihood methodology. Estimates of heritabilities varied from 0.02 to 0.09 for DC, from 0.15 to 0.23 for DFC and from 0.04 to 0.41 for GL, depending on the data set and the model used for each trait. Genetic correlations of DC and DFC with SC12 showed that it is possible to improve these female reproductive traits by selecting for increase in SC12. With respect to W12, selection to increase this trait should not produce significant changes in DC, but may increase DFC. Associations of the other female body weights with DFC and DC indicated that heavier females experience lower reproductive performance. Estimates of genetic correlations of GL with BW and W12 indicated that selection to change GL will result in correlated response in BW with no changes in W12.

The objective of this research is to show the changes occurred in the ephistemological format of religious taught in public schools after the promulgation of law number 9475/97 that altered LDB article 33 number 9394/96; and to reveal its ideological inclination. These changes were observed specially in São Paulo state in 2001, when the state department of education regularized the subject and the Board of Education implemented in the public school system. We researched the historical development of the relations between the Church and the State in Brazil and its interference in education since Jesuit school. This historical study observed varied forms in which religion appeared in the school system and confronted them with the new form adopted in São Paulo. We crowded our historical retrospective with the elaboration process of the 1998 Constitution and LDB number 9394/96 until the definition of the 9475/97 law. Thus, we proceeded to the ephistemological analysis of two distinct materials implemented by the Board of Education as of 2002, as the subsidy to Religion teachers in the official state schools during the first two years of the implement Our analysis of the presence of Religion in the public school system settled on a theoretical and ephistemological perspective that conceives religion, religiosity and religious or clerical institutions as historical products expressing the relations people share with one another, under the determination of distinct interest presented in society. Our research noticed that the redefinition of Religious Taught shows a catholic effort in order to respond to a new reality in which religious pluralism is manifested and even more openly in Brazil. This effort gives continuance to an ecumenical line adopted by the Catholic Church in the Vatican from 1962 to 1966, and also shows, as seem in the past the pressure of the Catholic Church, now joined to other small evangelical denominations, in the sense of keeping privileges in the public system by material subsidies for its evangelical action. It shows that catholics don´t accept the lay formula as a deal which consists of recognizing the religion as a private subject to preserve the public system against possible embarrassments.

The present study describes the preparation of amides containing the methylenedioxyphenyl group and also their activity against the leaf-cutting ant, Atta sexdens rubropilosa, its symbiotic fungus Leucoagaricus gongylophorus and the fall armyworm, Spodoptera frugiperda, larvae. From the bioassays it was observed that N-piperidine-3-(3 ,4 - methylenedioxyphenyl)-2-(E)-propenamide (65) was the most promising as insecticide agent among the compounds studied against S. frugiperda with an LD50=1.07 µg/mg larvae. Amide 65 and N,N-diethyl-3-(3 ,4 - methylenedioxyphenyl)-2-(E)-propenamide (66) were the most active against the symbiotic fungus; and N-pirrolidine-3-(3 ,4 -methylenedioxyphenyl)-2-(E)- propenamide (67) and N-benzyl-3-(3 ,4 -methylenedioxyphenyl)-2-(E)- propenamide (72) against the leaf-cutting ant. Additional studies were necessary to establish the structure activity relationship for piperamides. Thus, Combinatorial Chemistry technologies were employed and a solution-phase synthesis of indexed collection of amides was carried out, identified by Gas Chromatography coupled with Mass Spectroscopy (GC/MS), and screened against S. frugiperda. From this library, the most active compound identified was 1-[4- (trifluoromethoxy)benzoyl]piperidine, A8B1, which was then individually synthesized and evaluated. It has shown a LD50 = 8,15 µg/mg larvae, thus less active than amide 65 against S. frugiperda.

The fruit sector is found in expansion, being considered one of the fastest emerging and potential in the Brazilian agribusiness. The fruit chain has been affected by the increase in global competitiveness, where the big producers and retailers, focusing on the strengthening of their competitive position have amplified their strategies and acquisitions leading to a greater market concentration, a greater asymmetry of power and more complex configuration of this chain worldwide. The mango is in the spotlight in the Brazilian fruit culture, it is the third best exported fruit (113 thousand tons) in 2005. Brazil was eighth in worldwide production of mango in 2005, producing 850.000 tons. The northeast was the main productive area, responsible for 66% of all national production. The fruit sector is strongly affected by non-tariff barriers (NTBs), especially technical and phytosanitary. The restrictions have represented serious obstacles to the Brazilian fruit culture expansion in the international market. Therefore, the general goal of this research was analyze the productive chain of the exported Brazilian mango, focusing on the imposition of non-tariff barriers in the production, harvest, post harvest and distribution of national producers of mango in natura, where the study of case was selected as a more adequate method for the research and thus as multicase study was carried through. Some results found stand out: the technical barriers (having a phytosanitary state) are more frequent in mango exportation; the fruit is sold indirectly; the agriculture practice and non-tariff barriers are interrelated and finally, the consume behavior in different markets and consumers interfere in the process and practices adopted by the producers.

Boophilus microplus tick affects cattle productivity causing economic losses in the order of billions of dollars annually. It is know that tick saliva exert immunomodulatory effects, an evolutionary adaptation to the immune response of the host that can counteract tick feeding. It has been suggested that the outcome of many parasitic infections with regard to resistance or susceptibility is determined by the pattern of response involving Th1 and Th2 cells, which produce specific cytokines that may direct the immune response towards different mechanisms. Limited information is available regarding to the host response to B. microplus tick infestation. In an attempt to improve our knowledge about cattle immune-response to ticks, this work determined the expression levels of cytokines mRNAs in two groups of Nelore (Bos indicus) calves: one control and other challenged by tick infestation. Our results demonstrated a down-regulation of IL-2 (P < 0.03) mRNA levels in challenged animals, while no effect of tick challenge was observed for IL-4, IL-8, IL-12p35, TNF-α and MCP-1. The down regulation of an important Th1 cytokine suggests a tendency towards a Th2 response pattern, which is in agreement with similar studies conducted with other tick-host models.

Many GIS developers ignore the essential phases of the project like modeling databases, damaging the future development of the system. Considered very important to the project development, modeling will be broached in this article due to the great volume of existing data in transport systems and the need to manipulate them in a safe, reliable and fast way. In order to do it, a model for georeferenced database in being purposed, according to OMT-G graphical note model form BORGES (1997), to subsidize the management of the urban public transport. The method adopted for the modeling development was CÂMARA's (1999) abstraction levels. The application of the conceptual model developed will be carried out on a sample project considering the data referred to the public transport system raised at EMDURB Empresa Municipal de Desenvolvimento Urbano e Rural de Bauru, using a GIS SPRING tool and an Access database. Considering the difficulties the public administration finds in raising resources and the easiness to obtain these tools, considered one of public domain and another of low costs, the interested administration , specially in the medium and small cities, in introduce this model won't need great investments for the project development and the consequent procurement of georeferrenced information regarding the public transport.

In tropical regions, resistance of cattle to external parasites is an important factor determining efficiency of the production systems. The objectives in this study were to evaluate the degree of resistance of Nelore (NE), Canchim x Nelore (CN), Aberdeen Angus x Nelore (AN) and Simmental x Nelore (SN) females of several ages to cattle tick (Rhipicephalus (Boophilus) microplus), horn fly (Haematobia irritans) and beef-worm (Dermatobia hominis), and the possibility of selection to increase resistance of beef cattle to these parasites, through the estimation of genetic parameters of the degree of natural infestation, in order to furnish information to beef cattle breeding programs in Brazil. Two experiments were carried out. In experiment 1, 16 NE, 18 CN, 16 AN and 16 SN 16.5 months old females, were artificially infested with 20,000 larvae of cattle tick, four times 14 days apart each, were done, and from day 18 to day 22 of each infestation the number of engorged female ticks (≥ 4.5 mm) was counted on the left side of each animal. In this experiment, data were analyzed as the percentage of return (PR = percentage of ticks counted relative to the number infested), transformed to (PR)1/4, using the least squares method with a model that included effects of genetic group (GG), animal within GG (error a), infestation number (I), GG x I, and the residual (error b). In experiment 2, from six to ten cattle tick, horn fly and beef-worm countings on NE (184), CN (153), AN (123) and SN (120) naturally infested females of several physiological states (calves, pregnant and open heifers, primiparous cows with and without a calf and pluriparous cows with and without a calf), from July 2003 to December 2004, were done. In this experiment, data, transformed to log10 (n + 1), were analyzed by the least squares method with a model that included effects of genetic group (GG) of female, animal within GG (error a), year-season of counting (YS), physiological state, and GG x YS interaction. Besides that, genetic parameters of the degree of infestation by the parasites were obtained by the restricted maximum likelihood method, using models that included fixed effects of contemporary group (genetic group, year-season of counting) and physiological state, and additive direct, animal s permanent environmental, and residual random effects. In artificial infestation, despite the GG x I interaction, in general, NE animals were more resistant, followed by CN, and, at last, by SN and AN ones, which showed, respectively, the following percentage of return: 0.35 ± 0.06, 0.54 ± 0.05, 0.89 ± 0.06 and 0.85 ± 0.06. In natural infestation, the difference among genetic groups depended on year-season of counting, however, in general, NE females were less infested by ticks than females of the other genetic groups, while AN females showed higher infestation by horn flies and beef-worm than females of the other genetic groups. Heritability and repeatability estimates based on one-trait analyses were 0.12 and 0.12, 0.30 and 0.30, and 0.04 and 0.12, for infestation by cattle ticks, horn flies and beef-worms, respectively, indicating that it is feasible to obtain genetic progress for infestation by horn flies. The genetic correlations among these traits were low, except that between infestations by horn flies and beef-worms (0.60).
