This study sought to understand, from the perspective of young people, the knowledge built on the experience of being members of the Municipal Council of Youth of São Carlos (CMJ). For both, departed from the consideration that our experiences can be as educational processes. That is, people also educate from the experiences that are over their lives. As we all have the experience of participation in the world, all have different knowledge, based on which we live until then. The survey was developed starting from the recognition of the existence of an oppressive system dominant in our society, what do we do this mainly through the imposition culture. In this context, education is understood as a possible way forward in seeking the release of such a system. The intervention in the world for this is always political act. Thus, politics is not restricted to our relationship with the state, because no human action is depoliticized, every human act is loaded with ideas about the society in which they live. And education is also impossible to remain neutral and can serve both the system of domination, as tool to be desarmá it. They are mainly in social practices that are outside trigger the imposition of education that can develop educational processes that build the possibility of an education that liberates. Based on these understandings, this study had to investigate an area of youth participation, the CMJ, now based on assumptions that were as educational. It is a legally defined area of intervention for young people in the direction of municipal public policies. From the development of a qualitative research, which took as a tool for collecting data reflect the conduct of interviews with four young holders of CMJ, emerged 6 categories through which the results are presented: 1. participation, 2. expanding the visions of the world, 3. all: being-a-with-the-other in the world, 4. tolerance and solidarity, 5. living and talking, 6. the knowledge of experience. Participation may be desencadeadora of numerous educational processes by enabling the interaction between various people. Well, from the interaction that it triggers in a participatory environment, people can come to develop a dialogue, expand their visions of world and understand themselves as belonging to all. In this way are likely to modify their actions facing the reality in which they live. Thus, participation may trigger educational processes to promote citizen training for a conscious action in reality, in the direction desired by the subject that participates.

Cytogenetics studies in headwaters fishes have contributed significantly to the citotaxonomy and cytossistematic of these organisms. However, little is known about this diversity in the vast majority of river basins, especially among populations of adjacent basin headwaters, as it occurs in the Corumbataí area of environmental protection (Área de Proteção Ambiental APA Corumbataí), São Carlos city, São Paulo state. This way, an attempt was made to perform a comparative karyotypic analysis among the populations of many fishes of the Feijão upstream, tributary of Jacaré-Guaçu river, Tietê basin, and the Pântano upstream, tributary of Mogi-Guaçu basin, associating the cytogenetic data with the evolutionary aspects and the dispersal of the species in the region. Were studied species belongs of five Pisces families: Characidae (Astyanax altiparanae, Astyanax fasciatus, Moenkhausia sanctafilomenae); Curimatidae (Cyphocharax modestus); Prochilodontidae (Prochilodus lineatus); Cichlidae (Geophagus brasiliensis, Cichlasoma facetum); and, Gymnotidae (Gymnotus carapo, Eigenmannia sp.). The Geophagus brasiliensis, Gymnotus carapo and, Astyanax altiparanae species were characterized using basic and molecular cytogenetics tools aiming to verify the similarities and/or the chromosomal changes occurred between allopatric species, while in the others were observed inherent specific problems only in one population. A great similarity of the karyotypic macrostructure was observed between G. brasiliensis and Gymnotus carapo populations in both regions studied. However, in A. altiparanae specie differences were detected in the karyotypic formulae and in the number of 18S ribosomal sites. So, the data obtained to G. brasiliensis and G. carapo indicate that despite they are separated by waters divisors, occurred the maintenance of a very similar karyotypic macrostructure, possibly reflecting a karyotypic stability of this specie. However, in A. altiparanae specie we can observe a certain degree of evolutionary divergence between the analyzed populations, resulted of a flow gene restriction.

To understand the recent conceptions about childhood we have, necessarily, to seek in the historical aspects some answers for the present, due to the fact that a childhood vision also has historical and cultural relation, according to the Historical-cultural theory that grounded this research. In the long route of the history of attendance to childhood, researches and practices have been searching to affirm the importance of promoting a good quality education to all children - that involves diverse aspects of attendance, such as the ambient built. This work departed of the conception that the physical space of the infantile schools, appropriated at leisure activities of the children, can become a mediator of big relevance in the process of learning and development. Such being the case, the research matter that oriented this study was the following: What aspects are involved in the everyday of infantile schools so that the different spaces and equipments could work as mediators of the games of all children? The particular objective were: to diagnose the spaces (inside and outside) in the Infantile Schools of the municipal district of São Carlos; find out at schools which spaces are appropriated for games; analyze how those spaces are organized for the children plays and to identify/to analyze the mediation possibilities of the spaces in the learning and plays of the children. We used as a reference the Historical-cultural Theory because it acknowledge the game like main activity in the preschool phase, as long as for intermediate of it occur the most important changes in the psychic development of the child. The methodology used for the data collecting chose three different instruments: the first was a questionnaire applied at an extension activity about plays, at about 300 teachers of municipal district of São Carlos (SP), accomplished in the UFSCar (2006). The second instrument was a field research, in which was applied a questionnaire at 27 director of Infantile schools, about the physical structure of the schools and the activities accomplished in those spaces and; the third were observations of the games in the physical spaces of two units school. For the analysis of the data was chosen an only guideline that directed the over deepening of our glance in the specificities hinted by the data from the different instruments: the space like mediator of the playfully activities. Starting of that guideline could enlarge the analysis in four subguidelines, are they: 1. Physical structure - Quality of the spaces and learning of the children; 2. The outward and internal spaces like mediators of the activity kinds of the children; 3. Space, Game and Toys: the quality of the learning of the children and 4. The directed activities, the spaces and the teacher like mediator of the learning of the children. It is needed a profound reflection about insufficiencies interrelated to infra-structure and organization of the spaces in the Infantile institutions, conceiving that this is a big relevance factor in the mediation of the learning of the children. Our research also suggests that the space influence the teacher and contrary, being a reciprocal and continues motion.

The cities building is interconnected to the logic of wealth s accumulation, guide of the capitalist society where we are in. In this way, the city comes up with segregated, divided and dominated spaces which do not allow good conditions for housings and urban infra-structure to a big quantity of people, giving new shapes and increasing the actual social inequality. This work understands the cities building as a complex relationship between a lot of social practices which interacts one to each other, sometimes more conflicting and sometimes less conflicting, and the study will be concentrated on the social practice urban transformations, carried through the public government, on regions occupied by low income s population . From the premise that on the social practices coexist educative process, through of what the participants of those practices learn and teach, this study looks to identify the educational process present on the social practice studied. The work characterize by it self as a qualitative research done from a case study, which configures as a urban area occupied by a low income s population, identified as Orfanato , located in the south area of São Carlos city, interior of São Paulo State. From the intervention of the municipal public government this occupation is being completely removed to a region in the other extreme of city, and what, besides the removal, contemplate the building of a housing state through the mutirão process that when putted families from some city s region together and under the municipal public government coordination, edify a new district. The removing process ends in an Orfanato's population dividing, where part of the population have engaged in the mutirão program and some have not. In the mentioned case, I demand to identify the educative process present in such urban transformation, with emphasis for those process that point to indicatives of inhabitant s autonomy of the Orfanato, meaning, conducting their own lives.

In this work, I analyze the life story and education of four elementary school teachers, working in cycle I (Grade 1 to 4) of the São Carlos Municipal education system, selected because of their implementation of inter-multicultural teaching. To substantiate my theory, I researched studies related to life story, teaching graduation and inter-multicultural perspective in education. This work clarified and generated new knowledge in: life and educational background that contributed to the inter-multicultural initiative; the reasons behind this choice of work-orientation; their personal and professional characteristics; their continuous search for change and innovation inside their present school organization system and the difficulties found and the opportunities created by them during their work development. The analyzed results show the progress of the teachers towards the development in the inter-multicultural educational practices in many moments of their life and careers. The four teachers via life experience, formal education and practical work acquired and developed knowledge and approaches that influenced their pedagogic work towards the inter-multicultural education ideas. The result of this learning in their work, could have been noticed when it started to guide the choice of new teaching contents, adoption of news procedures and in the establishment of new relationships at school and in the classroom. I believe that understanding how the teachers were constituted as professionals that apply intermulticultural teaching practices, it will be possible to think about models and teaching application in teachers more adequate to reach hearts and minds.

The purpose of this thesis was to establish the conditions for silver-copper and silver-zinc electrodeposition from ammonium hydroxide and thiourea solutions, respectively, and to investigate the effect of added EDTA and HEDTA on the electrodeposition process. In this way, the influence of solution composition and electrodeposition parameter (deposition potential, deposition charge density, and deposition current density) on the electrodeposition process of silver-copper and silver-zinc was investigated. Relation between chemical species in solution and the reactions at the cathode/solution interface was established. It was verified that the formation of silver(I) complexes with ammonia or thiourea shifted the silver deposition potential to more negative value. As a result, the codeposition of silver and copper or silver and zinc was facilitated. On the other hand, EDTA and HEDTA acted as inhibitor of dendritic growth. This inhibition was attributed to EDTA and HEDTA adsorption on the platinum surface and growth sites of the electrodeposit, which decreased the current density of the charge transfer process. The silver-copper electrodeposit composition was a function of solution composition and electrodeposition parameter. On the other hand, the silver-zinc electrodeposit composition was almost constant, irrespective of the electrodeposition condition. Besides, the silver-copper electrodeposit was amorphous and composed by a mixture of silver, copper and silver-copper supersaturated solid solution. Sulphur was incorporated into the silver-zinc electrodeposit due to alkaline hydrolysis of thiourea in the cathode/solution interface. The silver-zinc electrodeposit was amorphous due to sulphur incorporation.

The city s transportation system has been a big problem in urban planning, due to constant increasing of vehicles fleet, absence of road network monitoring, air pollution, and conflicts between pedestrian and car. Therefore the development of alternatives that encourage the sustainable travel modes realization, as non-motorized modes and public transportation becomes necessary, reducing, consequently, the number of trips by car. In order to assist urban planning process on the sustainable transportation modes preference and to contribute to better urban spaces for citizens, the objective of this study is to analyze the existent relations between urban form of six traffic zones in Uberlândia city, Minas Gerais State and its urban transportation system, defining how physical features of a certain region influences people traveling behavior. Urban form variables defined as important to this study and analyzed on traffic zones level were: urban density; diversity of land use; quality of favorable places to nonmotorized transportation; availability of public transportation; routes design and connectivity; city topography. To determine the urban form influence on travel behavior different discreet choice models, multinomial logit type, were calibrated. First of all, the models were calibrated using only travelers socio-economic variables and then variables that characterize urban form were included. Results indicated that urban form variables don't have significant influence on the modal choice process in trips in the city, not being, therefore, determinant to define that transport mode must be used. Socio-economic variables, in special, the income and the trip distance were the most determinative factors for the transport mode choice.

This work reports the quantification of NADH formed by an immobilized enzyme reactor (IMER) of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) of T. cruzi using multidimensional high-performance liquid chromatography. For this, The IMER was used in the first dimension while an analytical C8 column was used in the second dimension. The conditions of the pre-treatment of the fused silica capillary tubes and the covalent immobilization of the enzyme into the capillary were successfully optimized, resulting in increased enzymatic activity and stability. Kinetic studies for the T. cruzi GAPDH-IMER were carried out to verify the influence of the immobilization over the enzyme affinity for the substrate and cofactor. The kinetic results for the IMERs of human and parasite GAPDH enzymes were compared to those obtained with the enzymes in solution, and showed that the covalent immobilization method used affected mainly the affinity of the human enzyme for the substrate. The human and parasite GAPDH-IMERs were employed for the ligand screening. The ligands recognized by the IMERs were the same identified by the enzymes in solution, showing that the immobilized enzymes kept the ability of recognizing the activity compounds modulators. The IMERs demonstrated to be a useful tool also for inhibitors binding reversibility characterization. In view of the high costs and difficulties involved on enzyme purification, the methods described in this work represents a valuable way of preserving enzyme activity and carrying out a variety of biochemical experiments.

The National Curriculum Parameters and Law 9.795 issued in 1999, which institutes a national policy covering environmental education, define that the environmental education should not be a school discipline but should be incorporated by all the existing ones. Aiming to check the way in which the orientation of the transversality is subsidized so that it can be concretized in the schools, this work uses the didactic books of different educational disciplines to understand how the multidisciplinar set of a same class approaches the environmental issues. The didactic books represent a huge investment on behalf of the Federal Government, who in turn analyzes, approves and purchases them for further forwarding to schools. As from this context the objective of the present survey is to understand how the knowledge, ethic and esthetic values as well as the political participation, covering the environmental issues, are approached in the didactic books of different school disciplines, resulting in contribution for an objective and critical usage of the school book as an environmental educational instrument. The survey was directed by the critical conception of the environmental education as it is understood that, when designing a fundamental role to the political dimension and educative práxis, it becomes more coherent with the search for transformation of the social-environmental reality. The methodology used was a qualitative textual analysis. As corpus of the analysis, didactic books were adopted; these books were purchased by SEE/SP covering each educational disciplines for the fifth year of the low school for the year of 2005. As analysis units, texts and chapters of the books that covered or should cover the environmental issues were used, and then these were unbuilt under the direction of a schedule, prepared based on elements that we consider essential for the educative work oriented to the environment, that includes handling of knowledge dimensions, of the ethic and esthetic values and political participation, which were subdivided in 21 parameters additionally specific. The analysis classifications were built a priori and based on existing trends in the educational field, as related to incorporation of the environmental thematic, as follows: silent, conservative, pragmatic and critical. Totally, 52 analysis units were selected distributed among the mathematics books, Portuguese language, sciences, history and geography. In general, most of them contemplated the environmental issue, however in a limited manner as the silent trend predominated in the three dimensions. In several parameters we were able to identify the presence of other trends, however, without a regularity in the approach, and this is assumed that there is no theoretical referential that subsidize the environmental discussions in the didactic books and that there is no concrete objective, on behalf of the state and of the didactic books, to transform the conditions of the social oppression and environmental degradation. The contradiction of the Brazilian state during this year is not founded only by the acquisition of material that does not company with the PCNs and Law 9.795, but for not considering them in formulation of other educational policies such as the PNLD, that does not cover the transversal themes in its assessment process. Thus, in its current materiality, the potential of the educational books, while a critical environmental educational instrument, is limited to the insertion of the theme in classrooms, and which should be deepened and enhanced by the school teachers.

The following research, qualitative in nature, originated with the practice of teacher researcher, the challenges encountered in teaching algebra and studies undertaken in respect of investigations mathematical as a methodology potentially motivating and positive results in relation to the development of language and the algebraic thinking. With the main objective of identifying evidence of formation and development of language and algebraic thinking of students who are starting to learn this subject, were the dynamics and communications that occurred in the development of exploratory-investigative tasks into two classes of 6th grade of Education Essential in a private school in the city of Americana - SP. The research was done in partnership with a teacher, who has teaching experience, had already researched and worked with exploratory-investigative activities. Researcher and teacher partner built the tasks undertaken during the investigation with the cooperation of the participants in the Collaborative Group for Research in Mathematics Education (GCEEM), of which both are members. Given the data of the search, a second goal was set: to identify some strengths and limits the use of exploratoryinvestigative tasks in the current educational context. With the focus on the dynamics of the classroom, in the statement provided by exploratory-investigative tasks and the teaching of algebra, it was possible to analyze further the first task, in which students had to explore a situation and analyze a regular basis. In exchanges of ideas among students, with the teacher and the records made during the development of the task, it was possible to identify the signs of formation and development of language and algebraic thinking. The data were collected and analyzed, according to various benchmarks theoretical research on mathematics, communication and teaching of algebra. To build the analysis of the goals outlined, first trying to identify and analyze the communications of the students and teacher at both the oral and written, during the completion of the task. Data were grouped into three blocs: (1) The movement of classroom research and evidence of language and algebraic thinking. (2) The movement of the classroom that led to conflicts and difficulties. (3) The conflict between the thought and language. During the review it was noted that the difficulties encountered by students originated in the absence of concepts - particularly that of variable - and the different language used by the teacher. It was possible to see that students, even with the thought arithmetic, were induced to use symbolic language - used by the teacher - without first developing the concepts needed. We could still see some limits within the educational context, such as the time required to give meaning to the concepts. By identifying the evidence, it became clear that students need to feel that to use the algebra symbolic is necessary- think scientifically - to solve problems, in another words, to be encouraged so that the algebra has meaning.

The thesis main goal was to test the partial applicability of the cartel party model (Katz and Mair), to understand the transformations in the national structure of the Workers Party (Partido dos Trabalhadores PT) between 1980 and 2005. The main hypotheses of the research derive directly from two of the three defining elements of such model. The secondary purpose was to build a general vision of the party organization during the period, focused on institutional changes, emphasizing motivations, strategies and conflicts associated to such changes. Two analytical dimensions were utilized: the functional and the organizational. On the functional dimension we detected that, during 25 years, the petista organization established a solid relationship with the state, and an estrangement from civil society. Such state links became essential for the party survival. The new situation affected the balance of power inside the party. On the organizational dimension, we observe a strengthening and greater autonomy of the party in public office , even capable to dominate the party in central office . On the other hand, the strategies of hegemonic party faction (Articulação/Campo Majoritário) shattered the intra-party democracy, increasing the importance and autonomy of the party in central office , while the party membership became less significant. The Michels iron law of oligarchy was corroborated: the Workers Party of Brazil could not escape from your oligarchization. If the party in public office and party leadership win with this new balance of power, there is only one looser: the party membership.

Campomanesia pubescens (D.C.) O. Berg., found in Minas Gerais, Goias and the Espirito Santo to Rio Grande do Sul, is a fruitful Myrtaceae whose gender has 25 species distributed from Mexico to Argentina and 15 of them natives of Brazil. Their seeds need of technical and scientific studies that could clarify their ecological characteristics, morphological and physiological, thus contributing to a better understanding. To this end, the objective of this study was to investigate aspects of the germination of seeds, seedlings, the emergence and the basic morphology of seeds of this species under different conditions in the laboratory and in a greenhouse. Their seeds have dimensions between 4.5 to 7.5 mm in length and 2.8 to 6.5 mm wide, the larvae infestation reached 8.92% of the fruits collected, the average number of seeds per fruit were extracted 6 And it was these seeds 38.45% and 61.55% empty seed floods. The water content found in its seeds was 53.5%, and in the curve of soaking, the protruding root occurred at 144 days, when the initial value was increased by 18.4% to mass on the mass of matter fresh start. It was observed that the final percentage and speed emergency seedlings was promoted significantly in substrates: coconut fiber / vermiculite (2:1) and vermiculite. In seedlings, the coconut fiber substrates / vermiculite (2:1), sand and vermiculite provided superior results to their lengths, as opposed to those that grew on the substrate of coconut fiber, which have significantly smaller lengths. Regarding the number of leaves per plant, there was no significant difference found between those who grew up in four different substrates. After 120 days of sowing, vermiculite, coconut fibre / vermiculite (2:1) and coconut fibre the percentage of 100% survival of seedlings as the substrate sand because his physical resistance offered to the emergence of seedlings, caused the loss of paracotilédones thus reducing the survival end to 90%. Looking at the mass of dry seedlings, roots, stems and leaves growing in coconut fiber substrates / vermiculite (2:1), vermiculite and sand had earned significantly higher in dry matter, with the weight of dry matter roots was higher against the portions of the air in all substrates studied: (0.12 g) greater weight of dry matter of roots, (0.02 grams) of the largest mass of stems and dry (0.03 g) greater weight of dry matter of leaves, consecutively, in seedlings that are developed in substrates vermiculite and sand. The germination (%) was significantly damaged at 40oC and water stress. When dried, fermented for 24 hours or for 4 days, 100% of the seed tested completely lost the ability germination. The results were as conductivity of the average value of 13.7 μ S.cm- 1.g-1 the rapid ageing significantly disrupted the proceedings of the seed germination.

The current paper analyzes the configuration of familiar educational practices in favorable environment related to the academic life of the offspring. The research which has a qualitative character was taken place through a study case involving families of a private educational institution in the city of Limeira in the state of Sao Paulo, Brazil. The main purpose is to identify which family practices can be transformed in cultural capital and analyze through those practices the familiar ethos subsequent to them. Regarding the studies in this field for the last few years, it could be verified the need for increasing in researches which take into consideration the Brazilian reality, its socio-economic context and the new family that is shaped according to recent demographic data. The results point to influences of the cultural capital and familiar ethos of families in social network with higher involvement in the academic life of the offspring and strategies to deal with the school difficulties of the children. The profile and the familiar practices also indicate the conversion of economic and cultural capital. This way, the study intends to supply with new contributions and strategies of following the study time and the educational institution chosen by the families, as well as give subsides to schools which seek an improvement of their relationship with the families and to elaborate educational propositions not only with higher quality but also adequate to their costumers needs. It was reported that the cultural capital of the families, if placed in conditions to allow its transmission and also allied to academic expectations, operates good influence in the academic life of the children, and can be showed in a favorable academic trajectory.

A great deal of microbiological and genetic research in the pharmaceutical industry is directed towards the development of effective strategies in the handling of microorganisms seeking the production of antibiotics that already known. In the process of obtaining clavulanic acid (CA) from Streptomyces clavuligerus, it is necessary to implement a system of strain conservation to maintain the capacity of microorganisms. Therefore, the purpose of this study was to test different preservation strategies of spores and vegetative cells of S. clavuligerus ATCC 27064 in order to ensure optimum conditions for the production of CA. Eight sets of vegetative cells stored in cryotubes were prepared, and they were evaluated for 12 months according to the number of growth stages (one or two 24-hour stages), the influence of the mycelium washing stage (washed or not), and the concentration of the cryoprotective agents (glycerol 10 or 20% v/v). Two sets of spores stored in cryotubes were also evaluated according to the concentration of cryoprotective agents. All cultures were performed in a rotating table incubator using the culture medium ISP1 for reactivation and complex medium for the production of CA. Morphology, cell growth, and the production of CA were evaluated in all cultures. The major findings were that the conservation of spores with 10% glycerol (E-10) allowed a more viable condition that the E-20 during the 360 days of storage, and the loss of CA production after 360 days was 18% but the condition E-20 was 50%. CL1-20 and CL2-20 were the best preservation conditions (more stable) for vegetative cells stored in cryotubes. Regarding the production of CA obtained, the maximum value was 1300 mg.L-1 at 144 h in the CNL 2-20 preservation condition.

The beams, pillars and slabs, are basic structural elements which compose the superstructure of the vast majority of buildings, including those of small size, which account for approximately 90% of them. There is a lacuna in the technical publications that address the structure of these buildings with numerical examples, analysis of the results, comments and general recommendations. The structures are differentiated according to their complexity. The modeling and analysis of a structure seeking their behavior closest to the real, even for simple structures are often complex and difficult. By the constant evolution of computer programs, each day it is getting a greater approximation of the real behavior of the structures. For the same structure it can be taken several structural models, resulting in different consumption of materials. This paper deals with the calculation of the superstructure of a two-story house usually composed by prefabricated slabs, rectangular beams and rectangular pillars which are presented through a general theoretical introduction with the main prescriptions of NBR 6118: 2003 and NBR 14859-1 (prefabricated slab requirements Part 1: unidirectional slabs) and the main recommendations of the Recommended Practice Ibracon for structures of small size. Through numerical examples with variations in the shape of the superstructure on the basis of two types of masonry adopted, this elements are calculated using the software for structural calculation, taking into account the calculation by tridimensional portico and grillage analogy. Important aspects of the structural point of view are presented. The results were analysed and compared also general comments and recommendation are presented.

This work presents a Virtual Reality environment dedicated to the analysis of tomographic images of Soil Science. Its architecture uses models proceeding from a volumetric (3-D) reconstruction algorithm, summed with several graphics processes of manipulation and visualization, in a way to provide immersion and interaction of the user with the virtual scene. Its validation was performed based on a case study involving the analysis of the porosity of the agricultural soil samples, which presents preferential paths for the water and solute flow (fingering). Results illustrate the consistent verification of the preferential paths of the agricultural soil samples, analyzed based on the developed environment.

The mercury is used in the industry, medicine, agriculture and other fields. However, little is known about its involvement with the bone metabolism. The aim of this study was to evaluate the physical, biochemical and biomechanical bone parameters in adult rats contaminated with mercuric chloride during the development phase. The animals were separated as control group: 10 male rats treated with saline 0.9% (0,1 ml/100g BW) and contaminated group: 8 male rats treated with mercuric chloride (2.5 mg/Kg BW). The animals were treated during 60 days, 5 days/week, by stomacal gavage. The body weight, femoral length and diaphysis thickness were measured. The mechanical properties (maximum and failure forces, stiffness and yield) of femurs were evaluated by the three-point bending test using the universal machine Instron model 4444. The bone volume was estimated by the Archimedes Principle. The wet and ash weight were also determined. The body weight, length and minor diameter of the femurs were not different between the groups; however the major diameter increased in contaminated group (p=0.0002). It was observed an increase (p=0.0044) of bone volume and a decrease of the bone mineral density (p=0.0009) and of the percentage of mineral material (p=0.0001) of the femurs of the contaminated group. The bone response to biomechanical test was similar in both groups. The rat contamination with mercuric chloride in the dose of 2.5 mg/Kg BW caused small alteration in the development of bones, as observed by the biometrical and biophysical parameters analyzed. However these alterations were not enough to induce modification of the biomechanical and biochemical parameters.

The approach of this study relates to the method of project management originated of the Theory of Constraints called Critical Chain. Beyond of the bibliographical revision on research methodology, production systems, project management, simulation of systems, Theory of Constraints and Critical Chain, a case study was accomplished to compare two methods of project management in a company of Industrial Goods. This company works with projects under order and it uses the Critical Path Method (CPM) to make your projects management. To compare the two methods of project management, historical information on the current management method adopted by the company had been collected, and for the method of Critical Chain some simulations had been done. Through these simulations it was possible to compare the compliments of the finish dates and the lead-time of projects to each one of the management methods. The results indicate for a better execution of finish dates when the method of the Critical Chain is used in the project management.
