The purpose of this dissertation is thinking the relationship between the military institution and politics in the period between 1964-1974, by an anthropological reading of the processes occurred in the core of the military hierarchy. Therefore, its analysis deals with the military careers constructed in this period, as well as the intramilitary political arrangements, as fields able to better evidence the movements in the command sequence under the new position assumed in the political context. In this way, based on an approach that considers the army as a specific social organization, that discussion aims to treat its relation with politics through its internal articulations, all of them concerning, as a last resort, to the central dimension of the military universe: the hierarchal organization.

The use of nature by local communities is based in a set of knowledge, practices and believes, developed through human culture and historical experience with the environment. Small-scale commercial fishermen from Upper-Medium São Francisco River, object of this study, are influenced by the dynamics of the environment cycle and by the ecology and biology of fishery resources, maintaining a very close relationship with them, for developing new knowledge and understandings which can provide better conditions of survive. More than that, the small-scale fishermen have self-organized for planning and practicing local management of fishery resources, which include local rules or institutions which define the rights and duties in the access and use of resources. The study of local ecological knowledge and common property systems developed by these communities are the mainly goal of ethnoecology science and of researches in common property systems, which support them as alternatives to the traditional scientific ecology and management of natural resources. This research was carried out between 1999 and 2001 with 7 field trips of 15 days each. Open and structured interviews were carried out, complemented by direct observation of the fishing activity, and the collect of fishery yield. The small-scale fishermen of Upper-Medium São Francisco River have demonstrated to pursue a detailed comprehension about the ecology and biology of the aquatic system and its fishery resources, on which they have based their fishery practices and common property systems, expecting to guarantee efficiency with sustainability. These local ecological knowledge and practices can contribute to develop a new interdisciplinary scientific view about ecology and management, putting together scientific and local experiences to produce a better use of natural resources, for these and the next generations.

This work approached the enzymatic activities, kinetics and mathematical modeling of the decomposition of Utricularia breviscapa from ºleo lagoon (21° 36' S and 47° 49' W), Luiz Antonio, SP. The experiments described the decomposition in function of temperature, availability of oxygen and carbon source. Samples of this macrophyte and water were collected in the oleo lagoon; incubations were prepared and maintained in controlled conditions. The results allow us to conclude that: (i) the U. breviscapa detritus are a heterogeneous substrata and presented two fractions: a labile/soluble (COPLS » 23.5%) and a refractory (COPR » 76.5%). The mass losses coefficients of the labile/soluble fractions (kT = 1.5 day-1) were higher than the refractory fractions (309 times in the aerobic condition and 469 times in the anaerobic condition). The increasing temperature and the dissolved oxygen concentrations favored the mineralization of the refractory fractions. The COPR mineralization in the aerobic conditions was faster than in the anaerobic conditions (1.5 times); (ii) the enzymatic activities of the cellulase presented a temporal pattern that was affected by the temperature, availability of oxygen and carbon source; (iii) stoichiometric ratio (O/C) varied in function of temperature and time; (iv) the oxygen uptake coefficients (kd) presented low variation in function of increasing temperature; (v) the increment on temperature favored the CH4 formation in the anaerobic decomposition of U. breviscapa and its emissions tended to occur earlier; (vi) probably, the enzymatic degradation of the cellulose in the anaerobic strata of sediments contributed to methanogenesis in the oleo lagoon; (vii) the simulations indicated that heterotrophic potentials of the oleo lagoon presents low variations during the year; the favorable period for detritus cycling is in the spring (October - November), in this period increments in mineralization occurs as function of increasing temperature and high availability of oxygen.

Effects of the direct and exchange electron-electron interaction, external magnetic field, symmetry of the charge carriers confining potential, radius, material g-factor, and also of the spin-orbit interaction in zincblende structure materials, are treated on the electronic and transport properties of semiconductor quantum dots (islands) charged by many particles. Three distinct kinds of confining potentials are considered: spherical, parabolic, and quasi-one-dimensional which, respectively, define a three-dimensional, two-dimensional, and one-dimensional island; the first one is more appropriated for the description of quantum dots formed in glassy matrices, while the last two better describe quantum dots litographically defined in a two-dimensional electron gas. Transport properties are considered in the spherical and quasi-one-dimensional islands, where we assume that the electronic current is in the resonant tunneling ballistic and coherent regimes, with essential role played by the excited states of the specific symmetry. We show that different geometries induce distinct level ordering in the island and that there is, in addition to the usual spin blockade, another kind of blockade mechanism which influences the system current; we label it by orbital blockade, because it is essentially due to the structure geometric confinement. We calculate the electronic spectrum of the many-particle system according to its symmetry. In the spherical case, we firstly use the LS-coupling scheme in order to obtain the eigenstates of an island charged by 3 electrons, following the orbital L and spin S total angular momentum addiction rules; we consider intensities of the magnetic field that allow us to neglect its diamagnetic contribution; the electron-electron interaction is treated as a perturbation in a Hartree-Fock way. In the following we use, in this same symmetry, the Roothaan and Pople-Nesbet matrix methods in order to deal with islands charged by 40 electrons, where the addition spectrum is calculated and Hund s rule is verified; we show how a magnetic field is able to violate such rule. The advantage of this numerical approach is the possibility to deal with a very high occupation in the island; the disadvantage is that their eigenstates do not have defined L and S values, as it is the case in the LS-coupling scheme. In the parabolic case, we employ a numerical diagonalization in order to obtain the island eigenstates charged by 2 electrons, without any restrictions regarding the magnetic field intensity or the system radius; we take into account both possible spinorbit couplings, one related to the implicit absence of zincblende crystalline structure inversion symmetry (Dresselhaus effect), and the other one related to the absence of structure inversion symmetry as caused by the confinement defining the two-dimensional electron gas (Rashba effect); we analyze the critical magnetic fields where both effects give origin to a intrinsic spin mixture in the island, inducing level anticrossings in the Fock-Darwin spectrum where intense spin-flips processes occur. In the quasi-onedimensional case, we just reproduce a known spectrum for an island charged by 4 electrons.

The scope of the current work was to investigate the effect of glucose, amonium acetate, DL-methionine, phosphorus, oleic acid and salt solution on the maximum specific growth rate (µmax), as well as the effect of sucrose and DL-methionine on the specific cefalosporin C production rate (µp), by Cephalosporium acremonium ATCC 48272, using factorial design and response surface techniques. The initial medium of fermentation was used according to factorial design and the experiments were carried out in shaker flasks at controlled temperature at 28 °C, initial pH of 7,0+0,1 and agitation speed 250 rpm. For both specific rate the variables involved were correlated by a fitted second order model. The canonic and surface response analysis showed a maximum specific growth rate of 0.22 h-1 obtained when glucose and amonium acetate concentration, were 4.2 , 2.5 g/L, respectively, and specific cefalosporin C production rate of 1.12 mgCPC/gcel.h when sucrose and DL-methionine concentration, were 10.5, 2.5 g/L, respectively, for a celular concentration of 14.0 g/L. The experimental design showed to be very efficcient in evaluating the bioprocess, as long as high values of µmax e µp were obtained in comparison with literature data. The feedforward neural network (FNN) was employed for modelling and simulation the effect of glucose, amonium acetate, DL-methionine, phosphorus, oleic acid and salt solution on the maximum specific growth rate. The network topologies were used with 6 neurons in the input layer, 22 hidden layer and 1 output layer. The data base for training the FNN was obtained from results of the factorial designs processed with a backpropagation learning algorithm. The surfaces response obtained by simulations for all range of glucose and amonium acetate concentrations showed inhibitory effect for the two substrates on the maximum specific growth rate. The results of the simulation are in good agreement with the experimental and statistical model results.

The present study was carried out in the estuarine complex of Itapessoca, located on the north coast of Pernambuco (PE) Brazil, at latitudes 07º 37 - 07º 41 S and the longitudes 034º 50 - 34º 55 W, from April 2001 to April 2002. The purpose was to characterize the environment and the ictioplanktonic community, attempting to recognize the distributional trends of these organisms, in order to evaluate the estuary s role as a site for the fish initial development phases. The water temperature, salinity and transparency were measured and the collected samples of the water where analyzed in order to estimate the levels of nitrite, nitrate and dissolved phosphate, ammonia, alkalinity and chlorophyll-a. The ictioplankton was collected through horizontal hauls with plankton net with 500 µm mesh. The hauls had a standard duration of 10 minutes, with the approximate speed of two knots. It was calculated the specific diversity of the fish larvae and the biotic and abiotic data were statistically related. A total of 87,758 eggs and 6,677 larvae were sampled corresponding to a total density of 39,445.34 eggs.100m-3 and 3,001.17 larvae.100m-3. The eggs and the larvae were present in all months and sampling stations. In relation to the fish larvae a total of 8 orders and 19 families were identified. The Engraulidae family was the most abundant (69,53%), followed by Eleotridae (7,73%) and Gobiidae (6,53%). Despite of the considerable integrity state of the Itapessoca estuary, the values of the diversity family indexes were low, in comparing to other estuarine areas. These low values can be explained by the dominance of the Engraulidae family, in all months and sampling stations. It was verified that the environment is rich in phosphate, with high levels of alkalinity; the levels of chlorophyll-a were in accordance with productive environments, but the low values of nitrite, nitrate and ammonia can indicate that nitrogen is a limiting factor of the local productivity, reflecting in the low occurrence levels of ictioplanktonic organisms at the estuarine complex of Itapessoca.

The objective of this project is to develop a methodology to evaluate the performance of a production system through the use of performance indicators regarding lean production in relation to the objectives of quality, manufacturing and productivity and its variables, quality, time, and cost. The expected objective is that this methodology will help the company to measure performance in a lean production environment. A presentation of the evolution of the lean concept will be performed, its principles and techniques, and the presentation of the three views of the lean thought. Within this context, a new view will be presented which seeks a formal integration between the production control and quality control at the shop floor level. The most used performance indicators will be described. They are used to measure the performance of a lean system and levels of employment for each indicator will be defined at the levels of the shop floor, company and supply chain. This project proposes a methodology that allows measurement of a company s performance that quantifies benefits that can be expected in the implementation of lean techniques. Finally, it will be shown through the application of the proposed methodology in the case study that the introduction of the concepts discussed in the fourth approach of lean production, which deals with the change of material and information flow from the production systems, helps the company to be more competitive. This concept translates into layout changes in the manufacturing process and in the production control systems.

This paper had the objective of applying a methodology which is aimed at the Public School, more specifically to Fundamental Education, as a contribution to the implementation of Environmental Education programs. The target public for this study were fifth grades students attending the state public school Antônio Militão de Lima and their respective teachers. In order to achieve the proposed objectives, a pedagogical intervention which privileged the Theory of Social Representation was established, based on the methodology developed by the educator Marcos Reigota and an interdisciplinary program, whose aim was to arouse the elements involved towards the forming of citizenship and ecological awareness. The teachers were oriented to the importance of collective and interdisciplinary involvement through offering capacitating courses and interaction with local reality. The results obtained demonstrated the true difficulties faced today by the Public Scholl, and their development of program allowed us to conclude that: 1) capacitating courses for teachers could contribute to arousing a mere critical vision of reality in the educator; 2) the results brought a series of information (informal) through interviews as well as through classroom discussions regarding the children s learning. The Theory of Social Representation and methodology of image interpretation were efficient to motivation students, teachers and other involved.

Down Syndrome (DS) is the major cause of mental retardation with a high incidence among human beings. Main features in DS include facial and dermatological features, congenital heart defects as well as immunological, gastrointestinal and endocrine abnormalities. Among a variety of cancer, a 20 fold increased risk of developing leukemia in younger people and an increased risk of testicular cancer is noticeable in DS patients. Most DS patients carry a complete trisomy of chromosome 21, but patients carrying a partial trisomy have also been observed. Analyses of partial trisomy of chromosome 21 have helped determining the minimal regions potentially associated with DS features. The DSCR2 gene located in the so-called Down Syndrome Critical Region 2 (DCR-2) codes a 32.8-kDa leucine-rich protein comprised of 34% hydrophobic amino acid residues. Little is known about the DSCR2 protein characteristics but many assumptions have been made according to in silico predictions. In this work, we used immunocytochemical and fluorescence assays to investigate the subcellular location of the protein encoded by the DSCR2 gene in transfected cells. It was previously suggested that DSCR2 was located in the plasma membrane as an integral protein. Interestingly, we observed this protein in the endoplasmic reticulum of cells. We also studied whether the location of DSCR2 truncated forms had different subcellular distribution and our observations indicate that it is probably not inserted in inner membranes once the fragments lacking the predicted transmembrane helices remained in the ER. We suggest that DSCR2 is located in the cytoplasmic side of endoplasmic reticulum by indirect interaction with the ER membrane or with another protein.

From the decade of 80 the religions had come back to the public sphere and if they had presented apt to represent important public papers in the continuous construction of the modern world. In the context of the globalization, the religious identities had in accordance with suffered to a re-significação from its originary contents the social process and the local lexicon. Of this form, the pentecostalismo if constitutes how much it saw alternative to the excluded individuals either finding an access to modernity either to the rescue of auto-esteem. The electoral process in allows them to verify the "desprivatização " of the pentecostais groups when producing new signs by means of the border politics and symbolic in which they fulfill the paper of expression of the group. Its articuladores if appropriate of religious goods and they associate them with the system of prestige and power. After that, they develop a new way to see the connection politics and religion, therefore they start to negotiate a new space front to the other social groups. The analyzed process if relates to the contextualização of the politics-religious career of pentecostais candidates e, respectively, the electoral strategies of the churches Assembly of Deus, Church of Evangelho Quadrangular and Universal Church of the Kingdom of Deus.

This work, entitled Inclusion of anthology of ideas from the english Garden-City into Modern Brazilian urban design: Águas de São Pedro developed in the Graduate Course in Urban Engineering at the Federal University of São Carlos (UFSCar), presents a study of the urban plan of Águas de São Pedro town, state of São Paulo, and its relation to the Garden-City s concepts, structured in four different parts. In its first part is given a brief overview of the history of post-Industrial Revolution urbanism, identifying the main urban typologies originating during this time and focusing especially on the Garden City typology from its English origin to its worldwide diffusion. From here, the study delves in the appropriation of this typology by brazilian designers (architects and engineers), articulated with economic, political, social and cultural analysis of this country in the first decades of the XXth Century. The third part analyses the universe of professional responsible for the creation of the city plan of Águas de São Pedro, urban engineer Jorge de Macedo Vieira, identifying his main influences and his productive evolution. Also, others professionals involved with this project are included. Finally, in the fourth part is done a comprehensive study of the adopted plan for the Watering town, along with its due empirical analysis, electing, from there, the elements that relate it to the Garden-City typology. This research therefore adds itself to others that study the use of the Garden-City urban typology in Brazil, contributing in this manner to extend knowledge about a school that participated actively in the history of brazilian urbanism.

This work presents a management tool that can be of great utility to private or governmental organizations, mainly the ones which are really considered to deal with the transit in a new, modern, efficient, efective and, over all, responsible way. For this, it makes use of modern computational techniques, as is the case of Geographic Information System - GIS, beyond the technique of benchmarking, an important basis of the Management of Total Quality. The Integrate Management System of Traffic Safety called SIG SET, developed for strategical level, produces ideas and concepts that take into account the management of transit security in a wide-ranging, sistemic and based on the information form. The SIG SET offers four databases and can operationally be implemented in integrated or modular form. For organizations with still a small structure, the implantation can start from the Database of Traffic accidents BDA, that uses a manager of relational database. However, with the evolution of this practice, the necessity of the implantation of a Space Database of Road System-BDSV arises , that own, amongst others, attributes of the interventions of the ways and volumes of traffic. In a subsequent stage, the georeferenced database of accidents can be implanted in software GIS (BDS). This new mentality of management, ripened and consolidated , the space database of benchmarking can be implemented (BDB). The BDB will be able to contain socioeconomic, social, cultural, human attributes, fleets of vehicles and accident rates of cities, states, regions or countries. The information of the databases must lead to the development of procedures that set up comparisons with pertinent referentials (benchmarking) and that have more positive security levels. This would stimulate the continuous improvement of road security, with the establishment of realistic and challenging goals of small, medium and long run. Based on the information generated by SIG SET, one can purpose interventions in the three traditional areas that compose the transit security: Education, Enforcement and Engineering; as well as to execute the verification of the effectiveness and efficiency of the same ones. The technique of benchmarking can periodically be carried out, applying the (re)evaluation of goals. The SIG SET unfolded for the operational level will produce, as a result, thematic reports and maps with the information of the databases produced. SIG SET is a tool indicated in the aid of taking decisions of governmental managing agencies and of organizations linked to the management of road security. An application of method SIG SET is presented in operational level, with the aim of exemplify its potentiality.

In the present work, Mg based nanocomposites were developed in the following systems: Mg TM, MgH2 TM, MgH2 MgF2 e MgH2 TM MgF2 (where TM means transition metal). The nanocomposites were processed by high energy ball milling and the obtained powders were characterized by in-situ X-ray diffraction during heating, transmission and scanning electron microscopy and differential scanning calorimetry. The microstructural evolution during heating of the MgH2 + 5%at%Nb was monitored by in-situ X-ray diffraction. It was concluded that the NbH/MgH2 and Nb/MgH2 nanointerfaces play major role on the hydrogen adsorption. These nanointerfaces act as fast diffusion paths or diffusion short circuits. The contribution of the thermodynamic attraction of these interfaces on hydrogen and its influence on sorption are also discussed. Both thermodynamic and kinetic effects accelerated the hydrogen desorption by the Mg-Nb composite. Based on the above, a mechanism for hydrogen desorption by the Mg-Nb by the Mg-Nb nanocomposite was proposed. It was observed that MgF2 greatly improved the desorption kinetics of hydrogen in the MgH2-MgF2 nanocomposite, showing it catalytic effect. The best result concerning the hydrogen desorption kinetics was for the [MgH2]90[MgF2]10 (wt %) nanocomposite. The on set desorption temperature of this nanocomposite was 253ºC. It was concluded that hydrogen diffuses through the MgH2/MgF2 nanointerfaces (fast diffusion paths). In this way, the hydrogen desorption kinetics was improved by the action of these nanointerfaces.

The changes occurred in the 80 s decade make the municipal districts took more and more responsibility about the 90 s decade urban problems. Among them, the dwelling access amplification and low gains community life s quality, guidelines contained in the Urban Reform. In this sense, municipal districts should develop public politics to social habitation involving habitational financing to low gains community, having in view that Federal and State Governments had absented themselves about this responsibility. Considering this context and having in view the actual Municipal s financial difficulties, it is necessary a better understanding about this phenomenon, elaborating strategies to solve it. This way, this work accomplish statistics acts carried out by Jaboticabal s municipal district in the 90 s decade, intending to analyze the Jaboticabal s public financing tendencies, through indicators.

The developed research focuse an analysis of the concepts that permeate the creation of the Rate of Urban Solid Residues. It detached the basic notions that permeate this theme, from the sustentability concept, as well as the technical variables and politics that involve the idea of the Environmental Rates. Due to the width of the theme and to the multiple variables that surround it, we based our research on two fronts: the theoretical, seeking to consider that several ideas and notions that permeate the theme; and other practice, that was the study of the experiences adopted in several municipal districts to carry out the Rate of Urban Solid Residues. We can highlight by those fronts that, in the theoretical part, we revised a vast bibliography regarding the economical instruments used for elaboration of public politics heading for the sustainable development; already in the practical part, we searched to establish some differences of adoption of these instruments and their juridical consequences of being implemented. Being like this, we can establish that the Rate of Urban Solid Residues is characterized as a necessary measure to set out the problems faced by the Municipal Public Powers with relationship to the produced garbage . However, for the complexity of the calculation base for collection, for the juridical aspects that orientate it and, why not to say, for the political difficulties to their implementation, it is necessary to go deeper into these studies, so that, through a deeper knowledge of the Theme, our Political Representatives as well as the technicians that elaborate the public politics can step in a less loamy soil, avoiding, thus, so many unnecessary wastes.

Ovariectomized (ovx) rat bones were used to evaluate the effects of sodium fluoride treatment on bone physical, chemical and biomechanical parameters. Wistar rats, with four months of age, were randomly divided in: basal, intact and ovx treated with sodium fluoride (0, 20, 40, 60, 80 and 100 ppm) groups. The basal group was sacrificed in the beginning of the experiment and the other groups after 2, 4, 6 and 8 months of treatment. Bone demineralization of femur due to osteopenia (induced by sexual steroids deficiency) resulted in lower values of bone density that resulted in lower values of biomechanical parameters when compared to intact group. Higher values of maximum force, failure force, resilience and stiffness of femur from ovx group treated with sodium fluoride, when compared to ovx group, were observed. The use of sodium fluoride as a therapeutic agent inhibited the osteopenia induced by castration and enhanced the bone quality, mainly when low dose was used (40 ppm)during short periods of treatment (2 and 4 months).

Environmental pulses occur very often in warm polymitic reservoirs and, together with shifts in the operational rules, lead to large internal temporal variability. The focus of this work was: (i) to evaluate the main characteristics and the complexity of physical processes during short-time events in a warm polymitic water body, Lobo (Broa) reservoir, and; (ii) to examine the potential of a hydrostatic three-dimensional (3D) numerical model at a coarse grid resolution to simulate correctly mixing and transport during short-time events in a warm polymitic reservoir. In this study we conducted two field experiments. In March-April 2001 a first collaborative field experiment, with intensive measurements that included both biological and physical processes, was realized in Lobo reservoir. During the 16 days experiment, a large spectrum of environmental conditions occurred: a storm, calm weather with moderate winds and the passage of a cold front. In May 2003 we conducted a second field experiment, also with intensive measurements, however focusing on the spatial variability of temperature and other variables in Lobo reservoir. A diurnal variation study was performed in both experiments. The 3D Estuary and Lake Computer Model was applied to modeling Lobo reservoir, S ao Paulo - Brazil, and was compared with data from both experiments. The reservoir spatial heterogeneity and rapid response to various pulses and diel patterns of heating and cooling were well reproduced by the numerical model. Thus, this can be a valuable tool for understanding evolution of the thermodynamics in a warm polymitic reservoir. Finally, in this work we highlight few inherent characteristics of polymitic reservoirs, which were found to be very important for the establishment of monitoring plans and the reservoir management.
