Wireless sensor networks are increasingly being deployed for fine-grain monitoring of physical environments subjected to critical conditions such as fire, leaking of toxic gases and explosions. A great challenge to these networks is to provide a fast, reliable and fault tolerant channel for event propagation. The protocol has to meet the requirements of querybased, event-driven and periodic sensor network application scenarios, even in the presence of emergency conditions that can lead to node failures and path disruption to the sink that receives those events. This paper presents a fault tolerant and low latency routing protocol that meets the sensor networks requirements for critical condition monitoring applications. The algorithm uses the publish/subscribe mechanism and the concept of event driven delivery, a technique that selects the shortest path for the notification of events, reducing latency. Fault tolerance is achieved through the triggering of a local path repair mechanism to find new paths with minimal number of transmissions. The protocol was implemented and simulated in the ns-2 network simulator and compared to the Directed Diffusion paradigm. Relevant metrics, such as end-to-end delay, energy dissipation, and delivery ratio, were evaluated showing that the proposed algorithm can be an adequate solution to meet the strict requirements of information propagation in real-time monitoring applications. An extension of the proposed protocol is also presented. This extension is in phase of implementation and simulation and it is expected to reduce data traffic and, consequently, reduce the energy dissipation. This new solution follows a hierarchical approach to propagate data through the network.

The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee and its rupture results in pain, instability, muscle atrophy and weakness. The quadriceps femoris muscle dysfunction is common before and after ACL reconstruction and can persist over years. A detailed understanding of neuromuscular function after ACL reconstruction is critical to the development of optimal rehabilitation strategies. The purpose of this study was to investigate the contributions of functional and morphological factors, in the muscle recovery, after ACL reconstruction. The effects of two therapeutic methods, usually utilized to recover muscle strength were also evaluated: Neuromuscular Electrical Stimulation (NMES) and eccentric exercise. Eight subjects (age = 31.3 ± 5.8 years) who had undergone ACL ligament reconstruction (mean 9.4 ± 0.7 months after the surgery) were randomly assigned to either an eccentric exercise associated with NMES (russian current) or only an eccentric exercise group. Only the involved limb was trained 2 days a week, for 12 weeks. The uninvolved one was also evaluated as reference. The quadriceps muscle function was evaluated by the measurement of the knee extensor torque during isometric and eccentric isokinetic contractions (30 and 120º/s) and by surface electromyography (EMG) of the Vastus Medialis Obliquos (VMO), Vastus Lateralis (VL) and Rectus Femoris (RF) muscles. The quadriceps cross-sectional area (CSA) was measured in six regions using Nuclear Magnetic Resonance Imaging (MRI-I). The initial evaluation showed significant extensor torque deficit both in isometric and eccentric conditions of the involved limb, compared to the contralateral one. There was significant muscle atrophy along the quadriceps extension, mainly in the distal thigh region. The EMG activity was lower for the VMO in all tested situations. NMES did not interfere in the gain of muscular strength, in any of the evaluated functions. The eccentric training increased significantly the isometric (from 198 ± 37 to 228 ± 48 Nm, p<0.05) and eccentric torque at 30 and 120º/s (from 227 ± 56 to 291 ± 65, p< 0.01 and from 199 ± 51 to 240 ± 63, p< 0.05, respectively). Quadriceps cross-sectional area also increased at all the evaluated regions for the involved limb, and the highest hypertrophy was at the thigh proximal region (from 169 ± 27 to 189 ± 25,8 cm2, p< 0.01 ), when compared to the distal region (form 31,5 ± 5,9 to 35,1 ± 6,1 cm2, p< 0.01). The EMG activity of VMO was recovered after the first six weeks of eccentric training. In the same period, the increased extensor torque showed correlation with the increased quadriceps cross-sectional area (r=0,81) and with the recovery of motor unit activation (r=0.69). After twelve weeks of training, there was correlation only between increased torque and cross-sectional area (r=0.78). In conclusion: 1) eccentric training showed to be a potent resource in the recovery of both morphological and functional factors of quadriceps, after ACL reconstruction; 2) NEMS did not interfere in the rehabilitation of these individuals.

In this work we will study through the differential operator technique the surface effect in anisotropic spin ½ quantum Heisenberg model, through theory of effective field (EFT), of a two-spins cluster, in case of simple cubic lattice. Those systems are characterized by the existence of the surfaces, thin films and superlattice, or the bulk. Therefore, the exchange interaction, among the nearest-neighboring, depends on the position of the atoms in the lattice: with the existence of surfaces we have for atoms in those plans, exchange interactions Js and in the adjacent plans interaction J. We studied the thermodynamic properties of the quantum metamagnet for the simple cubic lattice. The limit of stability of the phase antiferromagnetic is presented for the ground state (T = 0) and the respective diagrams of phases are analyzed. With the choice of the interlayer coupling interaction different from the existent in the plane (interplane), parameter λ (interaction λJ), we analyzed the influence of the crossover in the dimensionality [2d(λ =10-5) → 3d(λ =1.0)] of the system in the thermodynamic properties with the appearance of an anomaly in magnetic susceptibility. The surface effect in the thermodynamic properties is treated taking the system on thickness film l, with exchange interactions F and AF, where in that last one we applied an external field. We observed the behavior of the thin film in function of the temperature, number of layers, magnetic field and the ratio Js/J. Changing the exchange interaction between the elements and the layers of the thin film, we characterized the system as a magnetic superlattice. We chose four arrangements in the construction of the superlattice: different inter and interlayer ferromagnetic (F) interaction, the same for antiferromagnetic (AF), alternating the layers among F, and alternating superlattice composed of F (with l1 layers) and AF (with l2 layers), where l = l1 + l2 is the thickness of the film, where we observed the influence of the change of the exchange interaction in the thermodynamic properties and in the critical properties. Several phenomena were observed, as for instance, oscillation in the magnetizations and susceptibility for layers in certain values of the temperature and coupling parameters.

This study in the educational field displays the results of the bibliographic, documental and field researches. These were studies about the war through the teaching of Military History as this discipline is taught in the Brazilian Armed Forces schools. It highlights the study of war in History classes, the formation of the war leader in Brazil prepares the soldier for his war performance but this educational orientation has proven insufficient because it does not consider characteristics that are specific to the Brazilian military personnel. That s an educational process that focuses the History of War in a positive way and that does not necessarily prepare the officer for his career in the Brazilian society, a society that is not interested in the topic of Defense. That lack of interest can be explained by the fact that Brazil has rarely run any risks of attack against its territory or its sovereignhood. That s why the people find civical or subsidiary military action to be more important than actions of war. The Army schools programs do not approach polemic topics in the Armed Forces trajectroy in the Brazilian society. That s because our forces have never been on a battlefield. They have mostly done territorial defense and administration. Moreover, it has been involved in both social and political issues. Therefore, its educational formation aims for a performance that will not actually take place in Brazil. It s insufficient for the officer in his actual professional life. To prove our theory, we analyze the politics concerning national defense. These politics have existed since 1996 and we ll also see what they say about military performance and its scarce presence in the teaching-learning process. The element that brings about such analysis is the Military History content because it shows that the civilians society keeps getting more and more estranged from defense issues. Next, we present aspects of Military History in the three Brazilian army schools from 1996 through 2004. We also present its specific features in the teachinglearning process, the orientation for a study of war as an educational element in the preparation of an officer and the way this discipline is regarded by education authorities. We also show the way students of the three Brazilian military schools see Military History, a regular part of their formation, and the way they see their own preparation for the military career. Finally, we reflect upon the political and institutional role of the Brazilian Armed Forces, as it is in the National Defense Policy. We also reflect upon the difficulties to build a program that encloses the multiple functions to be performed by a Brazilian military officer nowadays.

The goal of this thesis is to identify innovation performances and technology strategies (TSs) adopted by medical equipment firms (those that are technology-based firms (TBFs) or not), located in São Carlos and Ribeirão Preto. Two hypotheses were delineated: (1) the medical equipment firms located in São Carlos and Ribeirão Preto that reached higher innovation performances in the last three years, differ from the ones that reached lower innovation performances in the dimensions of their technology strategies; and (2) the medical equipment technology-based firms located in São Carlos and Ribeirão Preto differ from the ones which are not considered as technology-based firms in the dimensions of their technology strategies. In order to analyze those hypotheses, data about TBF status, TS, and innovation performance were collected from thirty nine medical equipment producers located in São Carlos and Ribeirão Preto. An structured questionnaire was utilized for this purpose. The analysis of this information shows that the technology strategies adopted by the medical equipment firms that reached higher innovation performances are different in many aspects from the ones adopted by those that reached lower innovation performances. There are also differences between the TSs adopted by the medical equipment technology-based firms and the TSs adopted by those which are not considered as technology-based firms. Regarding the firms which reached higher and lower innovation, some indications were obtained that larger investments in internal activities of research and development and in external sources of technology, larger dedication to technology forecasting, and development of a wide portfolio of product and process technologies have allowed the firms to reach larger innovation performances. Regarding TBFs and Not-TBFs, it was observed that the TBFs have worked for the enlargement of their innovation and acquisition capacities of product technologies. Examples of their efforts: (1) large investments in internal R&D activities destined to innovations in product; (2) the number of engineers and scientists allocated to these activities; (3) the amount of key product technologies that those firms have; and (4) their large dedication to technology forecasting, etc. On the other hand, there were indications that N-TBFs (when they carry out some technological effort) dedicate themselves to the enlargement of their operation and adaptation capacities to operate their facilities more efficiently.

In the last decades, the high frequency dielectric response has been one of the most studied issues in the ferroelectricity area. The main dielectric characteristic is the strong dependence of the dielectric parameters (real and imaginary component of the dielectric permittivity) with the measuring frequency (dielectric dispersion). Among them, the perovskite-structured family, such as barium titanate (BaTiO3), pure and modified lead zirconate titanate (PZT and PLZT, respectively), and some others similar compounds can be emphasised. In order to explain such phenomenon some theoretical models have been proposed, nevertheless a major discussion about the true mechanism responsible for the microwave dielectric dispersion remains still open. In this work, a pressurecontrolled sample holder for microwave dielectric measurements is presented. The experimental set-up involves a coaxial line coupled to a pressure-controlled sample holder able to obtain the dielectric characterization as a function of the temperature. On the other hand, the microwave dielectric dispersion process was investigated in the relaxor and normal ferroelectric composítions of lanthanum modified lead titanate ceramics. The obtained results were discussed concerning a damped harmonic oscillator, considering the vibration of the boundaries of the polar regions, independently of their structure, as the mechanism responsible for the high frequency dielectric anomalies (dielectric dispersion and resonance) in ferroelectric systems.

The purpose of this work is to develop exact methods, based on Lagrangean and Surrogate relaxation, with good performance to solve the manufacturer s pallet loading problem. This problem consists of orthogonally arranging the maximum number of rectangles of sizes (l,w) and (w,l) into a larger rectangle (L,W) without overlapping. Such methods involve a tree search procedure of branch and bound type and they use, in each node of the branch and bound tree, bounds derived from Lagrangean and/or Surrogate relaxations of a 0-1 linear programming formulation. Subgradient optimization algorithms are used to optimize such bounds. Problem reduction tests and Lagrangean and Surrogate heuristics are also applied in the subgradient optimization to obtain good feasible solution. Computational experiments were performed with instances from the literature and also real instances obtained from a carrier. The results show that the methods are able to solve these instances, on average, more quickly than other exact methods, including the software GAMS/CPLEX.

The present work is divided in three parts. The first part deals with the purification and characterization of commercial chitosan from different suppliers. The second part describes the synthesis and characterization of biopolymeric Schiff bases obtained of chitosan. The Schiff bases were obtained from the condensation chitosan ( DA= 90%) with salicylaldehyde and its 5-bromo, 5-chloro, 5-nitro, 5-methyl, 5-methoxy sallicylaldehyde derivatives in acidic medium. Using the data obtained in the spectra of 1H NMR of the Schiff bases, it was determined the Mean Degree of Substitution ( DS ). The Mean Degree of Substitution ( DS ) ranged from 4.6% to 68.5% depending on the R group. The most substituted Schiff bases (highly DS ) has been used to obtain copper complexes. All the products were characterized by elemental analysis, hydrogen nuclear magnetic resonance (1H NMR) and infrared spectroscopy (IR). SEM photomicrographs was obtained with the purpose of verifying in morphologic changes in the biopolymerics Schiff bases as well as the copper complexes obtained from these bases in relation to starting chitosan. In a third stage, it was investigated the thermal behavior of biopolymerics Schiff bases and with the starting chitosan. An evaluation of the hydration and of thermal decomposition of chitosan and of the biopolymerics Schiff bases was accomplished using Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC). The chitosan TG curves under N2 presented two mass losses representing dehydration and decomposition of the polymer. Under air an additional step was observed due to the burnning of carbonaceous material. The biopolymeric Schiff bases decomposed in three steps: dehydration, decomposition and burnning of the carbonaceous residue in air. In both cases the DSC curves agreeded with the thermal events described by the TG curves.

This work was developed with the objective of to improve the state of the technique of spherical agglomeration of solids in suspension and to promote a progress in the necessary knowledge for its exploration in larger scale. We studied the agglomeration of salicylic acid crystals obtained from the reaction of sodium salicylate and sulfuric acid. The agglomeration was promoted using chloroform as bridging liquid, that was introduced in the solution immediately after the precipitation of crystals, the agglomeration being monitored by measurement of the suspension turbidity. The effect of variables as temperature, flow rate of chloroform feed, agitation and solid concentration on the following product properties were investigated: granulometric distribution, flowability, real and apparent densities, mechanical resistance, residual solvent, porosity and morphology. The results of this study allowed the identification of a new mechanism of agglomeration of solids from suspension and the possibility of controlling the process, in order to provide particles of a great variety of sizes, depending on the average size of the original crystals and according to the requirements of the final product application.

Natural zeolites are the most important inorganic cationic exchangers exhibiting high ion exchange capacity, selectivity and environment compatibility. Heavy metals are well known for toxicity and their disposal is a significant industrial waste problem. The goal of this work was directed to evaluate the selectivity of a purified homo-ionic clinoptilolite mineral for aqueous Pb2+, Zn2+, Cu2+ and Na+ ions at 0,005 eq/L and 303 K, interpreted through the application of empirical thermodynamic models to the zeolite phase (Margules, Van Laar, Wilson) coupled with a well established ion-interaction approach for the electrolyte solution (Pitzer). The present study considered the following stages: (1) adsorbent material: preparation and characterization; (2) aqueous solutions: nitrates of sodium, lead, zinc and copper; (3) equilibration of weighed amounts of homo-ionic clinoptilolite with a series of solutions containing the two competing cations; (4) analysis for aqueous cations by AAE; (5) construction of the equilibrium points; isotherm analysis; (6) test for thermodynamic reversibility; (7) empirical models for the zeolite phase (admitted as a solid solution) jointed to the ion-interaction model chosen for the aqueous solution; (8) equilibrium constant and Gibbs free energy for the ion-exchange reactions; phenomenological interpretation of the thermodynamic parameters obtained by means of the application of empirical models to the zeolite phase. The above procedure was, in the same way, followed for the ternary systems. The results obtained in this work shown that the empirical models adopted for the solid phase coupled to Pitzer s model for the activity coefficients in the electrolyte solution describe successfully the binary ion-exchange equilibria. The calculated equilibrium constant and the corresponding Gibbs free energy for each binary-exchange reaction resulted in a selectivity sequence, at the normality and temperature of this study, easily deduced as: 2 2 2 Pb Na Cu Zn + + + + > > . Besides, the parameters estimated applying the Margules , Van Laar s and Wilson s equations for cations in the solid binary mixture resulted in useful values quantifying adequately the cation zeolite framework interactions, thus, an alternative way to interpret the adsorbent selectivity from the charge and cationic radius effect. The ternary parameters obtained applying multi-component empirical models do not explain properly the non-ideality of ions in a solid mixture containing more than two components. This is in accordance with the results encountered in a number of publications on crystal structure of heulandite-group zeolites: these aluminosilicates are found to contain crystallographically distinct set of sites throughout the exchanger framework and that normally each set of sites is partially populated by the exchanging ions. As a consequence, activity coefficients for a multi-component exchange reaction cannot be predicted from appropriate binary data for a heterogeneous exchanger, since the phenomenological binary coefficients are complicated functions of each site set, population and composition, and both these properties will change on introducing other species of ion in the exchanger. In this sense, and from what were obtained here, is believed that multi-component solid phase nonideality must, at least, be interpreted through the application of statistical thermodynamic models considering the energetic heterogeneity of a number of site set and the charge density of the specific zeolite framework.

This thesis is concerned to the structure of a productive and organizational arrangement the mini-factory (MF) and its related concepts. A local subsidiary of an electronics multinational corporation was analysed, considering the main characteristics of the mini-factory. The thesis analysed the initial project for the mini-factory, its planning and implementation, the main changes and adaptations along the years, and the way that the mini-factory concept is used more recently by the company. The thesis also analysed the mini-factory impacts and contributions for the work groups and the qualification processes, focusing both people and organization. A case study research was developed, including interviews and data research, considering three distinctive periods of study. The variety of data collected supported the analysis of several important characteristics of the company and the way it works. The main results of this thesis show that the arrangement studied, called mini-factory by the company, is, actually, a new hybrid productive and organizational arrangement, that integrates characteristics of the mini-factory original concept with the related concepts. The results indicate that the adaptation processes, made during the years by the company, developed an arrangement different from those described by the other companies and even by the literature. These identified characteristics had been crucial for the good results achieved by the company and, nowadays, it is considered an example for the other subsidiaries of this multinational corporation.

The Manguaba river basin is located in the State of Alagoas, Brazil. It has an estimated area of 352 km2 and it drains part of the counties of Novo Lino, Jundiá, Porto Calvo, Japaratinga and Porto de Pedras. Since the riverhead, visible anthropic interferences can be detected. The river crosses rural zones (where sugar-cane crops predominate), as well as urban areas. With the aim of evaluate the environmental conditions of this river, and considering the regional context, this thesis is the first study in the State of Alagoas on benthic macroinvertebrates carried out in fluvial environment. The different anthropic activities developed along the river was the criterium to establish seven stations for collection purposes, that were plotted between 08º59 S - 35º42 W e 09º04 S - 35º22 W. The samples were collected on rainy and dry season, during 2001 and 2002. Samples of superficial water and bottom sediments were used for abiotic analyses. Fauna samples were done to study qualitative and quantitative features. Four higher groups were detected, with 76 taxonomic categories. Chironomidae (Insecta: Diptera), with 28 genera, was the most important among the 44 families identified. Larvae of Chironomidae, Oligochaeta (Tubificidae, Naididae), Hirudinea (Glossiphoniidae) and Mollusca (mainly Thiaridae) overtopped in high density and occurrence. Among Chironomidae Procladius and Chironomus were dominant in the area of the riverhead and Polypedilum (Tripodura) was an important group all along the river. Diversity and evenness indices indicated low to medium values. The similarity analysis and multivariate correspondence analysis distinguished the riverhead from the other sampling stations. Among the last ones, the results indicated higher impacts at on the stations near urban areas. This could be confirmed by the faunistic composition of taxonomic groups known as tolerant.

The family farmers play an important role in the Brazilian agricultural production. However, even though they occupy a prominent position in the agricultural production in Brazil, there are not management techniques specifically suitable to family farmers. Focusing on commercialization and vertical coordination, this dissertation has as main objective the development of management prescriptions related to procurement and marketing activities undertaken by family farmers. Computational simulation, based on System Dynamics methodology, was the main instrument to support procurement and marketing decisions. Interviews with thirty three vegetables family farmers and five of their main suppliers, all located in the region of São Carlos SP, provided the real data for the design of the computational model. The empirical research revealed that family farmers do not plan procurement and marketing appropriately, although they manage to compete with non-family production. The use of governance structures based on trust seems to be the main cause of their survival and success. The simulation based on System Dynamics helped the design of models that represent and help the decision making related the procurement and marketing by family farmers.

This paper aims to show the governmental action on the Housing Municipal Policy implementation on the 1990´s within Santos City, São Paulo State. To do so, it was made a research about the Federal Housing Policy on the BHN period and also on the posterior period till 2000 in order to verify the trajectory of the federal policy on the housing field. The Municipal Housing Policy conquered special importance after the promulgation of the 1988 Constitution when the Federal Government gave to the municipalities the responsibility for their own urban policies. Within this research, we aim to present the factors that influenced the formulation and implementation process and the results of such policy in this period. We presented this policy content on three distinct administrations associated with the instruments which made the implementation possible: The ZEIS law – Special Zones for Social Interest, the FINCOHAP – Popular Housing Construction Incentive Fun, Municipal Housing Council and the Municipal Housing Conferences. This choice for Santos City is due to the master student has been a participant person on the Santos Housing Policy process. The used methodology was based on gaining information through out the hypotheses made for this research. It has been verified, with this study, that Federal Government on the BNH age had the same housing policy for many Brazilian cities, not considering the specificities of each one, conceiving resources for housing constructions. On the post 1988 Constitution period, the municipalities began an autonomy process of their urban politics. On the Housing field, the Federal Government gave the responsibility for the federative institutions in order to formulate their policies without conceiving resources. Generalizing, so these new policies let the cities economically dependent on the Federal Government which don’t have federal channel to redirect resources like for Health and Education, making impossible the municipality to supply its housing deficit by their own.

The purpose of this study was to evaluate relative the physiological adaptation the activities of enzymes Lactate Dehidrogenase LDH (glycolytic) e Citrate Synthase CS (oxidative) and to the Anaerobic Threshold (AT), to the exercise in treadmill in rats submitted to the photostimulation for low-intensity laser (780 ηm) in the main participant muscles of the march. Fifty-four male Wistar rats had been part of the study. These animals were divided in four groups: Two had remained in rest (1) GRC, being one of them irradied (2) GRL, and other two were submitted to an aerobic treadmill training program during 5 weeks and to a multistage treadmill test of increasing intensity (3) GEC, being one of them irradied (4) GEL. The irradiation for infra-red laser (780 ηm) was made daily in number of four (quadriceps, maximum glúteo, soleus, tibialis anterior) in each back leg of the animals, totalizing 8 applications for animal/day, using (dose, 3,8 J/cm2; power, 15 mW; time, 10 s, continuous) during 5 weeks consecutives. The multistage treadmill tests of increasing intensity were made once a week totalizing 5 evaluation, in order to obtain blood samples for determination of the AT. In the analyses electrophoretics and spectrophotometic of the LDH and CS muscles samples (soleus, TA and cardiac) were removed 48 hours after the last exercise bout. The laser to promote increase in the oxidative metabolism of 2% a 78%, the exercise of 18% a 75%, and action combined of 43% a 92%; Apparent systemic action of the laser was detected in cardiac muscle with increase in the activity of the CS and reduction of the LDH. The group GEC and GEL showed increase in the maximum speed, in the speed corresponding to the AT and a trend reduction of the blood lactate concentration during the training period. However, no significant difference occurred between two groups though the GEL had shown higher values. These data suggest that the aerobic treadmill-training partner to the low-intensity laser can to promote physiological adaptation in the direction of increase oxidative capacity in the animals, represented by increase of the CS, reduction of the LDH and by the higher degree of effort to reach the Anaerobic Threshold. This similarity has a utility therapeutic practical.

The recent changes in the work s world have modified and amplified the performance field of the ergonomics. Through a brief methodological discussion about the Ergonomic Work Analysis and a bibliographical revision about undertaken ergonomic interventions, it was verified that the results of work transformation through Ergonomic Work Analysis not always will be positive. Consequently, this work had an objective of analyzing an ergonomic intervention accomplished in a powdered detergent company, due to understand how ergonomic actions are incorporated for the different social actors and how the company, through the management, could appropriate of the results in behalf of the production.

This thesis aims to analyze the process of policy formulation for public management reform during Fernando Henrique Cardoso s tenure (1995-2002), while grasping the scope within which this issue gave rise to national State Reform. To this end, we have used agenda-setting theoretical models that highlight the dynamics behind the ideas and the symbolic representation surrounding policy making, as well as empirical data garnered from the main state publications released during this period. Agenda-setting was studied in terms of the principal line of thought on Brazilian government and public administration, by analyzing the definition of the problems as presented by the government and the solutions chosen by the creators of reformist policy. These ideas, jointly with the analysis of political and institutional structures during the Cardoso government, allow us to understand how this issue rose in importance until they became a component of the government s agenda.
