This research is aimed to break down into steps and analyze the process of institutionalization of Corporate Social Responsibility (CSR). Therefore, a bibliographical survey of the New Institutionalism in its sociological perspective was performed in an attempt to describe and characterize the steps of the institutionalization process, since the referred literature fully explains the adoption of social and environmental practices in the business environment. Subsequently, a bibliographical survey of CRS, as a subject of analysis, and of the main social and environmental variables (internal and external) that are part of the referred subject, was performed, based on the most accurate indexes and reports in Portugal and Brazil. Thus, considering the conceptual frameworks and case studies developed it has been possible to analyze the degree of institutionalization of each variable that composes the social and environmental responsibility in the studied companies, as well as the most important factors in the institutionalization process of CRS. In this context, car assembly plants set up in Portugal and Brazil were analyzed in order to verify the similarities and differences in the institutionalization process in the two countries. The results demonstrate that institutionalization can be broken down into additional and consecutive steps, demystifying the characterization of the process of institutionalization of organizational forms and practices as something that exists for the only purpose of determining whether something is or is not institutionalized. Besides, it was concluded that the most privileged dimensions and variables depend on the specific demands of each organizational field.

This thesis work evaluated the formative potentialities in mathematical explorationinvestigation for the professionals teaching mathematics for children from six to eleven years old pre-school teachers, teachers of the elementary school, and a professor of mathematics (student in pedagogy) focusing: (a) the development of exploratoryinvestigative activities in a group of teachers which periodically meet together for share new professional experiences, and (b) professional pedagogic practices developed with reference to the mathematical exploration-investigation. The main question was described: What are the formative potentialities of the mathematics exploration-investigation for teachers engagement in developing mathematics teaching? . The context of this work was to obtain the data collection of a continuous forming group involving the participants and the researcher, in order to investigate this thesis qualitatively in narrative style evaluating the life experiencing representation, valuing the perspectives of the group participants, producing a text based in a continuous movement for life, representing, evaluating, and representing again. The material analyzed was composed by: video recordings transcribed by the researcher; written and oral narratives from researcher and participants; researcher´s diary notes; written data of teacher and their students and pictures. According with the data of the authors who analyze the mathematics explorationinvestigation, the professional apprenticeship, and formation in their life we could conclude that the explorative-investigative activities were the responsible for the increasing teachers knowledge of geometrical contents in their substantive and syntactic structures, and reflections about didactic resources. Besides, it was possible to evidentiate elements that relate tasks in a sequence, and the activities developed as promoter of problematization of professionals practices of the teachers. In the classroom of the first years of the elementary school, the activities were transformed in opened problems and explorationinvestigativon, with encouraging the creation of an environment of negotiation of meaning and communication of ideas with the children. This has enabled teachers apprenticeship for improve their knowledge about their students and how they might arguing, questioning and establishing investigative positions in geometry class and in other contents and about way of teacher s intervention to enable such situations.

A lot of cities have suffered the serious problem about the high volume of waste caused by the civil construction, either in new construction works or in renovation and demolition, concerning with an irreversible phenomenon which is associated with the urban development, the population increasing and the industrialization. The necessity of the minimization of the problems concerned to the environmental, urban and the public health degradation, associated with the bad way the waste is put down and the precariousness of the right conduct, suggests an achievement of some work in this way, having in sight a better life quality for the present and for the future generations. The research will aim at a diagnosis of the waste of the construction work and demolition of the borough of Rio Claro-SP, showing subsidies for the proper management of waste produced, aiming at inquired research of preexisting solutions and producing alternative solutions, which can contribute to a public politics of local productive arrangement in the sector of management of the civil construction waste.

The Law #10.257/2001 creates some instruments for urban management, among which the Study of Neighborhood Impact (EIV), which despite being required by this law, still hasn t been convincingly regulated by the municipal governments. The present thesis deals with the Study of Neighborhood Impact applied to supermarkets in cities of different sizes (Ribeirao Preto, Sao Carlos and Ilha Solteira) considering their local and regional impacts. The objectives of this research were to identify, present and evaluate the post-building impact related to this kind of enterprise, its valuation, the identification of its influence areas and the related policy acts. In order to reach these objectives, a combination of System of Geographic Information, cross-impact matrix, application of questionnaire and in loco data collection has been used. As a result, it has been verified that the impacts occur independently on the size of the enterprise and of the city. However, they do occur in different magnitudes, and the location of the enterprise in the urban environment is a relevant factor for minimizing them. Still, the verification of attributions to the physical environment in the analysis of the impacts has been considered important in measuring them, so as to include the environmental aspects together with the urban and socio-economic ones in the characterization and analysis of the impacts. Therefore, the EIV sets itself up as an instrument of urban management, allowing more efficient management to urban conflicts and contributing with sustainable development of urban environment.

This study aims to better understand the taking care and teaching practices of day-care educators, who can be either teaching or non-teaching workers. Qualitative approach was chosen so that the research methodology was defined as coherent with both the object and the theoretical references of the study. The resources for collecting data were the questionnaire and the semi-structured interview. For data analysis, the concepts of meaning and sense were used from the activity theory (LEONTIEV, 1978), taking as a starting point the objective and subjective conditions of the educators practice. The results show that meaning and sense of childhood change throughout the historical process, and that this change has an effect on the construction of the Childhood Education. Nowadays, the conception of early childhood education places emphasis on the actions of taking care and teaching as indivisible. However, this meaning is not consistent with the sense some day-care educators gave to their practices. Regarding the objective conditions, there was a concern present directly and indirectly in the educators answers: the importance of having a pedagogical project as a foundation of taking care and teaching practices.

The wood has many different characteristics, resulting, in part, of the conditions in which the tree grows. The physical conditions of the wood are also influenced by its complex internal structure, resulting in an anisotropic behavior. Within this variability, its best use and application can be reached through non-destructive methods. The non-destructive methodology is performed to verify the existence or inexistence of discontinuities or defects, without changing its later use. This work aims at presenting the non-destructive techniques in wood with potential use in Brazil. It also aims at applying the ultrasound technique in lumber pieces of Pinus sp of structural dimensions, with the purpose of verifying the accuracy of such technique, comparing it to the values obtained in destructive tests (static bending tests). The coefficient of determination (R2) obtained from the regression line between the static modulus of elasticity and dynamic modulus of elasticity with the use of ultrasound was 0.66, that allows affirming that this technique has accuracy in the assessment of mechanical pieces of wood.

The capture-recapture process, largely used in the estimation of the number of elements of animal population, is also applied to other branches of knowledge like Epidemiology, Linguistics, Software reliability, Ecology, among others. One of the _rst applications of this method was done by Laplace in 1783, with aim at estimate the number of inhabitants of France. Later, Carl G. J. Petersen in 1889 and Lincoln in 1930 applied the same estimator in the context of animal populations. This estimator has being known in literature as _Lincoln-Petersen_ estimator. In the mid-twentieth century several researchers dedicated themselves to the formulation of statistical models appropriated for the estimation of population size, which caused a substantial increase in the amount of theoretical and applied works on the subject. The capture-recapture models are constructed under certain assumptions relating to the population, the sampling procedure and the experimental conditions. The main assumption that distinguishes models concerns the change in the number of individuals in the population during the period of the experiment. Models that allow for births, deaths or migration are called open population models, while models that does not allow for these events to occur are called closed population models. In this work, the goal is to characterize likelihood functions obtained by applying methods of elimination of nuissance parameters in the case of closed population models. Based on these likelihood functions, we discuss methods for point and interval estimation of the population size. The estimation methods are illustrated on a real data-set and their frequentist properties are analised via Monte Carlo simulation.

Deltamethrin is a synthetic pyrethroid pesticide, type II, considered of low persistence in the environment and widely utilized in agriculture and aquaculture to control plagues and aquatic parasites respectivamently. In spite of it low toxicity in mammals, this pesticide can be extremely toxic for fish. In this study, we evaluate the effects of a sub-lethal concentration (7.3 μg L-1, 50% of LC50-96h) of deltamethrin (formulation BUTOX®CE25) on the in vivo cardio-respiratory function of Nile tilapia (Oreochromis niloticus), are species of high economic potential. The cardio-respiratory parameters (O2 uptake - V&O2 , respiratory frequency fR, gill ventilation - G V& , ventilatory tidal volume VT, O2 extraction from the ventilatory current EO2, and heart frequency fH) were measured in a group of intact fish (GC), under normoxic conditions, during 24 h. After this period, another group of fish (GE) was exposed to deltamethrin and kept under these conditions for another 24 h period. During these periods the cardio-respiratory variables were continuously monitored. In another series of experiments, a group of non-intoxicated fish (GCH) was exposed to normoxia (PwO2 ~ 140 mmHg) and subsequently submitted to graded hypoxia (PwO2 = 100, 70, 50, 30 and 20 mmHg), while the above cardio-respiratory variables were continuously measured. A fourth group (GEH) was exposed to deltamethrin and submitted to the same hypoxic leves. Just after the exposure to deltamethrin fish presented a reduction in 2 V&O (mLO2.kg-1.h-1) which recovered gradually and reached initial (control) values after 18 h. Meanwhile fR (breaths.min- 1) remained unchanged in response to the toxicant. The G V& (mLH2O.Kg-1.min-1), however, increased significantly in the first 6 h of exposure to deltamethrin, returning to the initial values after 9 h. The G V& increased as a consequence of a proportional enhancement in VT (mLH2O.kg-1.resp-1). Immediately after the toxicant administration, fish presented a significant reduction in fH (bpm) and this bradicardia remained for a period of 12 h, after which this variable returned to the control values. Fish exposed to deltamethrin and submitted to graded hypoxia presented a significant reduction in 2 V&O , while their critical oxygen tension (PcO2) increased in relation to the control group. This indicates impairment in the capacity of oxyregulation of intoxicated fish. Also during graded hypoxia G V& and VT of fish exposed to deltamethrin increased progressively, while fR did not change. The fH was significant lower (bradicardia) in all hypoxic tensions. In conclusion, when Nile tilapia is exposed to sub-lethal concentrations of deltamethrin (formulation BUTOX ®CE25), the cardio-respiratory variables of this species stabilize after about 24 h, indicating a fast recovery to the toxicity of this pesticide. The cardio-respiratory responses to hypoxia, however, are impaired by deltamethrine exposure, suggesting that an adequate aerobic metabolism is important in the detoxification of this pesticide.

In this study, in the first step, Indium tin oxide nanoparticles were synthesized via a non-aqueous route involving the solvothermal treatment of indium (III) acetylacetonate and tin (IV) chloride in polyethylene glycol Mw=1000. The use of microwave heating reduced the reaction time considerably when compared to traditional heating methods. An analysis by transmission electron microscopy (TEM) revealed particles of relatively uniform sizes and shapes. The high crystallinity of the material was observed by high resolution transmission electron microscopy (HRTEM). The nanocristal size founded by count was 5,1nm. A powder X-ray diffraction analysis indicated that all the materials were crystalline. Infrared spectra confirmed the presence of organic material on the nanoparticle surface. By thermogravimetric analysis (TGA) determined that 11.3% of the total mass corresponds to the polymer. Resistivity values below 10-1 Ω.cm were obtained in thin films and pellets, and semiconductor behavior. In the second step, a model to control the covered area of graphene oxide (GO) sheets by ITO nanoparticles was proposed. The method used was add graphene oxide at the synthetic route to obtain pure ITO. The composites were characterized by XRD, FT-IR, TGA and TEM. XRD results for the synthesized materials confirmed the diffraction patterns of ITO in the different composites synthesized. Through the analysis of FT-IR was possible confirm the presence of the polymer formed on the surface of the oxide nanoparticle and functional groups of graphene oxide sheets. The polymer attached on the oxide surface is responsible for the strong interaction between the ITO and graphen oxide sheets. TEM images for the samples with different cover percentage showed the controller achieved with the synthesis proposed. The composite with 100 or 10% of metal oxides covering the sheets surface did not show the presence of nanocrystals out sheets. The percent value of the covered area obtained of 15% founded by image J analisys is near to the calculated value. From this value we can say that the model works well to control the covered area of GO by nanocristals. The electrical resistivity values found are comparable to the pure ITO, however, with a smaller amount of ITO.

Rabies is a zoonotic viral disease caused by a virus of the genus Lyssavirus that affects several species of mammals. Rabies remains a global public health threat that kills more than 55,000 people per year mainly in developing countries, this disease once established do not have a specific treatment. The RV envelope is composed of a glycoprotein, known as a unique antigen capable of conferring immune response against the rabies, and therefore, is the focus of research for development an efficient and safe recombinant vaccine based on this viral antigen. Cell line stably transfected S2 Drosophila melanogaster have been used in the production of many heterologous proteins and has been studied for the production of the rabies virus glycoprotein (RVGP) in our laboratory. This approach involves the selection of high producing cell populations; procedure that requires considerable periods of time (months), increasing management and costs of production. In this sense, in recent decades, many systems focused on the expression of heterologous proteins by transient expression of genes, were analyzed because they allow obtaining significant quantities of recombinant protein in a short period of time (weeks). For the use of transient transfection technology can be found a variety of methods and available agents, such as electroporation, cationic lipids, cationic polymers and calcium phosphate precipitated. The choice and optimization of each of them depends mainly on the cell type and protein being expressed. Thus, the objective of this study was to evaluate the transient expression of the glycoprotein gene of rabies virus (RVGP) in insect cells of Drosophila melanogaster S2 lineage, evaluating the vehicles transfection: calcium phosphate, cationic lipid (Cellfectin) and cationic polymer (ExGen500 and JetPEI). In order to determine the most efficient transfection agent, experiments were performed in 6 well plate and bottle of 100 mL of culture, which analyzed the influence of cell density, the concentration of DNA and transfection reagent volume on the expression of RVGP assessed by ELISA and fluorescence microscopy. Yields ranging from 50-90 ng/107cel were obtained in different experiments on multiwell plate, suggesting strong effect of ratio DNA: transfection agent used. Comparison of transfection agents showed no significant differences. In transfections made in suspension culture was analyzed the effect of the plasmid (whether or not the signal of BiP cell secretion) on the expression RVGP. When we used the plasmid containing the signal BiP (pMTiRVGP) were obtained 160 ng/107cel of RVGP production, and 200 ng/mL of volumetric production without significant differences between the different transfection agents. However, significant differences were found when we used the plasmid not containing the signal BiP (pMTRVGP), with the RVGP production was 60 ng/107cells in cells transfected with Cellfectin, ExGen500 and calcium phosphate, except in cells transfected with JetPEI was reached a production of 120 ng/107cells. In preliminary experiment bottle type "spinner" with a working volume of 60 mL were achieved expressions of 140 ng/107cel of RVGP in cells transfected with JetPEI and calcium phosphate. This suggests that optimization of culture conditions and transfection are possible to increase recombinant protein expression in cultured on a large scale.

Given (X; 0) C (CN; 0) a weighted homogeneous germ of hypersurface with isolated singularity and f : (CN; 0) - C a germ of function finitely determined with respect to X, we show that UBR(f;X) = U(f) + U(X; f), where U(f) and U(X; f) denote the Milnor numbers of f and of the fiber X \ f��1(0), respectively, and UBR(f;X) is the Bruce-Roberts number of f with respect to X. We show that the logarithmic characteristic subvariety, LC(X), is Cohen-Macaulay and we get relations between the Bruce-Roberts number and the Euler obstruction. Given F : (CN; 0) ! Mm;n(C) a holomorphic function germ, let (X; 0) be the isolated determinantal singularity given by X = F-1(Ms m;n(C)) where Ms m;n(C) is the set of the complex matrices with rank less then s, with s an integer number between 0 and minfm; ng such that N < (m - s + 2)(n - s + 2), we will define the vanishing Euler characteristic of (X; 0) and the Milnor number of a holomorphic function germ with an isolated singularity at X, f : (X; 0) - C.

This work highlights the implementation, development and application of the Ultrafast Nuclear Magnetic Resonance (UFNMR) technique, proposed by Frydman and co-workers. Through this technique, it is possible to perform multidimensional experiments in a single scan, thus reducing the experiment time drastically, which can be a fraction of second. This study shows a practical protocol, which was optimized for the implementation of the first ultrafast 2D NMR COSY and HSQC experiments performed in Brazil and, to our knowledge, in the southern hemisphere. This process involves the setting of several parameters from the initial calibration of encoding gradients and pulses, to the setting of a specific acquisition scheme required by the technique. Furthermore, some important operational aspects are discussed in order to contribute, even more, to future implementations to be carried out safely and efficiently. Also, as part of this study, a software in C language was developed to obtain the real-time processing (1 second) of the UF-NMR data, and this was incorporated in the Bruker software for the acquisition and processing of NMR data - TopSpin® version 3.0. Finally, two studies were also performed using the UF-NMR experiments. The first one was the real-time identification of a mixture of flavonoids (epicatechin, naringenin and naringin), which underwent on-flow chromatographic separation, in a commercial HPLC-NMR system. UF-COSY experiments were performed during the chromatographic run, so that it was possible to obtain the 2D NMR spectra related to each flavonoid and to successfully follow their separation over the course of time. The second application was the monitoring of the hydrolysis reaction of the 2-(4-nitrophenyl)-1,3-dioxolane acetal. The hemiacetal intermediate of this reaction has a short lifetime, being difficult to identify by conventional NMR. Therefore, HSQC-UR experiments were performed during the reaction development, thus, it was possible to characterize the presence of the hemiacetal intermediate. This assignment was confirmed by quantum calculation of 1H and 13C NMR chemical shifts and of the NBOs (Natural Bonding Orbital).

The objective of this study was to investigate the evolution of experimental activities presented in textbooks on chemistry from Brazil Empire until the present. The experiments are analyzed in books from the Library of Textbooks of College of Education at USP / SP, dating from 1875 to 2010. For the analysis of experiments, the books were divided into 6 (six) periods: 1875 to 1930, from 1931 to 1941, from 1942 to 1960, from 1961 to 1970, 1971-1996 (SCHNETZLER, 1978), from 1997 to 2010. With the exception of the first period, the criterion adopted was the time of utilization of the first Brazilian chemistry textbook; others refer to periods of validity of the major Brazilian educational reforms. When relating the experimental approach to the current legislation, there is consistency between the proposal and what fits in the books and also closely related to the historical moment. Through the analysis of the experiments we observed three different approaches: demonstrative, empiricist-inductivist and investigative. The experimental investigative activities are highlighted in the books of the last period.

The Brazilian economic scenario at the beginning of the twenty first century presented a reasonable growth of the stock market. The Brazilian capital market reached impressive valuations. The growth of this scenario is strongly linked to and popularized by financial self-help market, which involves books and lectures that are elaborated by financial advisor. This research aims to analyze and to map these agents and their strategies employed to invite new individuals to markets circuits, encouraging them to become investors. However, it was possible to verify a cultural niche , embeddedness in a familialism ethic. Thus, it evidence that the financial world have been gained legitimacy because it has operated as a kind of moral device, being recurrent in the neopentecostal pastors speeches, and through financial education, it conducts social policies that reached low-income sectors, bringing cognitive and symbolic implications for the Brazilian society.

Increase of dietary lipid and carbohydrate with concomitant reduction of protein level is a promising prospect to suply the fish energetic demand and to spare dietary protein to the growth. Study of digestive enzymes secretions combined with growth parameters and metabolism can help solve many nutritional problems in the aquaculture. The aim of this work was investigating growth, digestive efficiency and metabolic responses of juvenile tambaqui (Colosssoma macropomum) fed with 3 carbohydrate/lipid ratios (CHO/L): 30,5/13,7% (diet I); 40,5/9,1% (diet II); 50,0/4,8% (diet III). The diets were isoenergetic and isoproteic. The experiment was carried out in the facilities of the Adaptive Biochemistry Laboratory, Genetics and Evolution Department at Federal University of São Carlos. The following parameters were assayed: fish growth, digestives enzymes (unspecific proteases, trypsin, chymotrypsin, unspecific lipase, amylase and alkaline phosphatase), metabolites (glucose, lactate, pyruvate, ammonia, protein, fat acids, triglycerides, amino acids and glycogen), and the enzymes LDH, MDH and GDH. Fish fed with the diet II presented the highest values of weight gain, length gain, relative food-intake ratio, and condition factor. However, fish fed with diet III depicted the worst performance and the lowest HIS when compared to fish fed with other diets. Tambaqui digestive enzymes were responsive to dietary carbohydrate/ lipid ratios. Fish from diet III showed significantly reduction of alkaline phosphatase activity and T/C ratio; moreover showed increased of lipase activity (in all gastrointestinal tract) and amylase activity (stomach and anterior intestine). In relation to metabolism, it was detected lipolysis in livers in accordance with the increase of the dietary CHO/L ratio. Muscular glycogenesis, lipolysis and gluconeogenesis from amino acids to energetic supply were observed in fish fed with higher dietary CHO/L ratio. The plasma metabolic profile reflected the blood metabolite delivery function among tissues underlining biochemical adaptations due to alterations in the fish feeding. In conclusion, dietary carbohydrate to lipid ratios induced digestive enzymes of tambaqui. The increase of CHO/L ratio resulted in fish growth decrease, augmented the liver lipolysis, increase the muscular glucogenesis, lipolysis and the gluconeogenesis. The fish metabolism seemed to be predominantly lipolitic suggesting that, in this species, lipids are more efficiently used to energy storage than carbohydrates. Diet III deprived the fish of energy resource resulting in protein utilization for this purpose. Tambaqui spared protein to growth utilizing mainly carbohydrate and lipid when fed with diet II.

Beverage industries in Brazil are in pursuit of improvements in customer services to fulfill the new marketplace needs, taking into consideration both the change in consumer, habits which now show a preference for healthier goods, and the recent growth in all social economic levels. The services that need more attention are the sales and distribution departments. The former because it is trying to improve the service level to adjust to the new reality, the latter because it faces the challenge of optimizing and properly playing its role in terms of performance and cost effectiveness. Considering that improvements in sales service levels may result in a worse performance and higher distribution costs, conflict between the areas are probable and expected, especially when each one is trying to improve results individually. The service level in sales within the beverage industry could be divided into components, for example: weekly visit frequency, visit duration, weekdays for visiting clients and deadlines for delivering the goods. The primary objective of this study is to verify two hypotheses: (a) whether the manner in which sales functions are organized affects performance and costs in beverage distribution and, (b) in that case, to which degree it quantitatively affects the company s expenses. In other words, to verify that service levels defined by the sales planning team and offered to clients directly reflects the performance and delivery cost for each service level component, with an associated specific cost. Once this cost aggregation is proved, the intention is to analyze and quantify it. In order to validate these hypotheses, a case study is developed in a typical beverage company in Brazil, which has already defined their new service levels without considering its effect on performance and distribution costs. As a consequence of these actions, the studied company had observed a significant rise in these costs and to revert the situation, has considered new alternatives to balance the sales service levels, regarding delivery costs and distribution performance. The company then decided to support the development of a technique known as territory compacting, aiming to improve logistics performance and reduce distribution costs while service levels remain unaffected. Among the precautions adopted to avoid possible service level deterioration, the studied company monitored client perception related to its distribution effectiveness, before and right after the territory compacting was implemented in the most relevantly attended city. Using the technique named Correspondence Analysis, client perception was then rated for various specific sales service levels to avoid damaging the most valued ones for each client. Main operational indicators in sales and distribution are also compared, taking into consideration variations of different periods in cities where territory compacting was applied. Bearing in mind the nature of this study and the participation of the research author, this case study can be sub-classified as action research.

Brazil is one of the greatest sugarcane producers of the world, with figures that exceeds 620 million tons in 2010/2011 harvest season. There is an expectation of strong increase of Brazilian sugarcane production in next years due to increase in sales estimulated by the low production cost of sugar and alcohol and also the increase of the internal and external demands for ethanol, in substitution to fossil fuels. At the same time, environmental issues led the publication of a specific legislation that established a schedule to the next years to stop sugarcane burning previous to hand cutting, a traditional activity. This legal restriction brought a new scenario, as an increasing amount of biomass, that used to be burnt, will be available for other uses such as ethanol extra production, by technologies still in development or to energy generation, similar to what is done with bagasse (by means of cogeneration). Independent of its use, sugarcane and its biomass processing configures a complex operation as big volumes of materials are handled using high cost equipment which a high interaction among them. Several systems can be configured to do this task, varying equipments and settings of the operations performed by them. The selection of equipment and operational proceedings is one of the main tasks of managers at sugarcane mills. In order to help in decision taking situations, in this study, a discrete event simulation model was designed and modeled to represent sugarcane harvesting systems with biomass recovery. Conventional sugarcane harvesting and partial cleaning sugarcane harvesting were represented in a unique simulation model, as well as the correspondent alternatives of biomass recovery and delivery at mills. The operational characteristics of these systems were previously set in the model and can be modified through electronic spreadsheets, interfaced with the simulation model that manages the input and output of data. Field tests were done to evaluate equipment performance and generate data to the simulation model, which was used in two studies. In the first study, three sugarcane harvesting and biomass recovery systems were simulated using the data collected at each field test, representing those systems differently, under their own observed conditions. In the second study, the three systems were again compared, however, under the same conditions, with the same set of assumptions, in order to permit their comparison in equal basis. All scenarios considered a typical mill operation that processes two million tons of sugarcane per harvest season. The simulation model enabled the evaluation of the selected systems considering sugarcane and biomass production as well as their economic evaluation.

Folha de S.Paulo and O Estado de S.Paulo newspapers were sources of a study about the presence of slogans in educational speeches. This research asserts that communication by slogans damages the understanding of the message that is intended to be conveyed because once it´s effective, slogans cease the debate and damage the reflection about the theme that is being discussed. It can be concluded that the slogan “Education to everyone gave place to “Education with quality”, but it also alerts that the sense of quality presented itself as related to the idea that education is meant to make people able to find jobs. As the newspapers alert, once they are businesses, they are ideologically related to the market and when they choose to announce a specific piece of news, they automatically obscure another that, by being kept in silence, also symbolizes, in this research, the silence of education that combats reifying.

The quadriceps muscle weakness and atrophy after the anterior cruciate ligament (ACL) rupture, is present before and after its reconstruction, and are important limitations that restrict the return of subjects to activities of daily living and sports. The combination of reduced synthesis and increased levels of protein degradation results in a rapid loss of muscle protein. The rapid muscle proteolysis occurs in several animal models and in different conditions in humans, and are mainly associated to the ubiquitn proteasome system (UPS). Neuromuscular mechanisms are associated with atrophy and weakness of the quadriceps muscle after ACL rupture and reconstruction, but the molecular pathways involved in this process are unknown. The identification of these pathways may facilitate the establishment of therapeutic strategies to alleviate the muscle deficit. Thus, the objective of this thesis was to evaluate the effect of ACL transection of rats in the expression of genes of UPS (MuRF-1, Atrogina-1), as well as the expression of myostatin (involved in control of muscle mass) by the Real Time PCR (polymerase chain reaction) technique. It was evaluated the content of ubiquitinated proteins by Western blotting and the cross-sectional area of muscle fibers (CSA) of the vastus medialis (VM), rectus femoris (RF) and vastus lateralis (VL) of the quadriceps. Elevated Atrogin-1, MuRF-1 and myostatin mRNA levels were observed after ACL transection in all muscles assessed, as the reduction of CSA in VM and VL muscles. The results of this thesis contributed to the understanding of the mechanisms of quadriceps muscle atrophy after ACL transection.

Projects of capital goods with Engineering-to-Order (ETO) productive typology are usually complex due to its size and level of customization and technology. Because of these aspects the achievement of success demands a management effort and can be conditioned by several elements, among which are the Critical Success Factors (CSF). In this sense, the proposal for this research involves the identification and analysis of the relationship of these factors with the success obtained in ETO projects using a multidimensional concept that involves efficiency, organizational learning, preparing for the future and customer satisfaction. From these principles a survey was conducted involving 67 companies and 182 projects with above characteristics. Data analysis was initially performed by the technique of Factorial analysis, whose results led to combine 38 Critical Success Factors identified in the literature on 12 new factors with better ability to explain the observed phenomenon, namely: Uncertainty management, Organization and Planning, Productivity management, Robustness of the team, Management of technical performance, Learning and adaptation, Integration with external stakeholders, Reliability of the team, Schedule optimization, Precaution against technical failures, Guidance capacity and Precaution against supply failure. These new factors led to an analysis by multinomial logistic regression technique, which identified significant factors to explain each of the success dimensions. For the efficiency dimension this factors are Planning and organization, Reliability of the team, the Guidance capacity, Integration with external stakeholders, the Technical performance management and Schedule optimization, to the extent organizational learning are the optimization schedule, Productivity management and Precaution against technical failure. To the preparing for the future dimension this factors are the Management of the technical performance, the Reliability of the team, Schedule optimization, the Precaution against technical failures, the Learning and adaptation, and the Organization and Planning, the Guidance capacity. For the customer satisfaction are the Reliability of the team, the Learning and adaptation, Precaution against failure of supply, Organization and planning, Precaution against technical failures and Contingency management. Thus, from a scientific standpoint, the results obtained in this thesis extends the understanding of the topic studied and provide from the managerial point of view a framework that can guide and support decision making by managers of this type of project.
