The theme of this thesis is the use of allegories and allegorical interpretation in the works of Plato. It arises from the verification of a paradox between the occurrences of this rhetorical or literary device and the negative comments that the philosopher addresses sometimes to them. In certain passages of his dialogues, such as the beginning of the Book VII of The Republic (514a to 517a), Plato presents metaphorical narratives which add themselves, without any restriction on his part, with the argumentative development of his ideas. In other parts, however, as at the prologue to the Phaedrus (229c-230a), he expresses unfavorable opinions about the allegories and allegorical interpretation. In this sense, the philosopher seems to reject a discursive device that, paradoxically, he usually employs. My goal is therefore examine comparatively the allegorical passages of the corpus platonicum to reveal its constituent structure and the possible variations to which they are submitted. What I hope, in fact, is to find the theoretical notions that allow dissolve the paradox and restore the internal coherence of platonic thought on the issue of allegories.

The changes observed in the morbidity and mortality profile, characterized by the greater occurrence of chronic illnesses and possible functional and cognitive losses due to aging, produce specific demands for health care. The objectives of this study was to evaluate and compare the health, functionality, cognition and mood of the elderly and to assess and compare the health and burden of formal and informal caregivers of elderly at three public health institutions with different care profiles (hospitalization, outpatient and long-term). This is an observational, cross-sectional, comparative with a quantitative approach , approved by the Research Ethics Committee . Data were collected in the first half of 2014, with instrument for sociodemographic, health, Mini Mental State Examination (MMSE), the Clock Test, Geriatric Depression Scale (GDS), Basic Activities of Daily Living Scale (Katz ) and Instrumental Activities of Daily Living (Lawton) for seniors, caregivers were applied in the last issue of Zarit Overload Scale and Self Reporting Questionnaire SRQ-20. The sample consisted of 140 elderly persons, with 37 people from a Long-Term Care Institution for the Elderly (LTCIE), 53 users from a teaching hospital and 50 from the Teaching Health Service (USE), and 50 caregivers, 15 formal caregivers anda 35 informal caregivers, located in an interior city in the State of São Paulo, Brazil. Elderly subjects in LTCIE, 54.1 % were male, and most entirely dependent for both BADL (51.4 % ), and to IADL (62.2 % ) and 100 % of the evaluated elderly patients with cognitive decline ( average 6.6 points) . At the Teaching Hospital, 50.1 % male , 58.5 % for independent BADL, IADL and 43.4% to 62.3 % of the elderly patients with cognitive decline (mean 17.3 points). At the USE, 68 % female, 59 % for independent BADL, IADL and 40 % to 48% of elderly patients with cognitive decline (average of 19 points). Regarding the presence of depressive symptoms, the incidence in institutions were 29.7%, 41.5 % and 36 %, respectively. Of formal caregivers, there was a predominance of women (86.7 %), and an average of 7.5 hours daily working hours. Emotional stress was evaluated by SRQ-20, showing data that the question " poor sleep " was the most frequent (53.3 % ), followed by questions "feeling tense, nervous or worried " (40%) and " feel -If tired " (40%), revealing that 26.7% were diagnosed with emotional stress. After application of the latest issue of Zarit Scale, 40 % answered feel" a little overwhelmed" and "moderately overloaded" (26.7%). As for the 35 informal caregivers evaluated, it was revealed that 77.1 % of them lived with the elderly . There was a predominance of women (85.7 %), and 42.9 % represented by children , with care time of 6.5 years and an average of 19,8h a day taking care of the elderly. After burden assessment, 31.4 % reported feeling " a little" overwhelmed and 25.7% "very overwhelmed”, revealing that 17 (48.6%) had mild overload. As for the emotional stress the most reported issues were "feeling tense, nervous or worried" (80%), "sad feeling lately" (62.9 %) and "sleep badly" (60%) revealing that 16 (45.7 %) had emotional stress. The results show that the functional and cognitive impairments were identified in different contexts among the elderly, and the related cognitive decline mainly to old age. About caregivers, higher levels of burden and emotional stress were found in informal caregivers. These results reveal the requirement to look at this population’s needs in the different contexts more closely, planning interventions to improve these people’s health and work conditions.

Interval training (IT), combined with pharmacological therapy, has been strongly recommended for the management of coronary artery disease (CAD) and control of cardiovascular risk factors. However, the best protocol to be used it is still unclear. In this regard, the IT protocols based on ventilatory anaerobic threshold (VAT) can be an effective and safe strategy to prescribe the intensity of the exercise training as well as to promote improvement of the aerobic functional capacity, metabolic profile, cardiac autonomic modulation and to reduce inflammatory markers. Moreover, the adaptive responses to IT may differ between individuals. Part of this biological variability may be explained by the genetic polymorphisms involved in the synthesis of structural proteins or on the circulation enzymes. Based on this context, this thesis involved three studies. The first and second studies were conducted to investigate if the IT, based on intensities between 70 and 110% of the workload obtained in the VAT, could be effective to improve functional aerobic capacity and metabolic profile. Moreover, it was investigated if there was a relationship between the improvement in cardiac autonomic modulation with the reduction of the Creactive protein (CRP) in patients with CAD and/or cardiovascular risk factors. The results of the first study showed that the IT program increased aerobic functional capacity and reduced body mass and body mass index. The second study found that after the IT program, there was an increase of the parasympathetic autonomic modulation that was associated with a reduction in CRP levels. Given these findings, the third study was designed to investigate the improvement of the functional aerobic capacity and changes in lipid profile induced by IT, in relation to the apolipoprotein B (APOB) and the angiotensinconverting enzyme (ACE) genes polymorphisms. In this study, it was observed that the increase of the functional aerobic capacity was associated with the presence of the ACE I allele, whereas patients with polymorphism -7673G>A, in the APOB gene, presented increase of the low-density lipoprotein (LDL) levels over time. Considering the findings from these studies, the IT protocol promoted improvement of cardiac autonomic modulation, increase of aerobic functional capacity, reduction of inflammation e improvement of metabolic profile. These benefits on the cardiovascular and metabolic systems contribute to control of cardiovascular risk factors and primary and secondary prevention of CAD. Moreover, this IT protocol provides new possibilities on cardiac rehabilitation field, with respect to exercise training prescription at the VAT level.

The data released by 2010 Census (IBGE) demonstrated a reversal in the migratory flux in the central area of São Paulo-SP. After decades of decrease in population, neglect and lack of investments, the center of the city started to gain new inhabitants in the first decade of the XXI century. The purpose of this study is to analyze these changes and investigate the production of urban space in the central area of São Paulo between the years 2000 and 2010. Through the case study of Paim Street (Bela Vista), the research intends to discuss this production, not only as a result of the guidelines defined by the city Master Plan, but also as a reaction of real estate market. Despite the legal advances, with the approval of federal Law 10.257 in 2001, the Strategic Master Plan in 2002, and the positive aspects of the population growth in the central area, the investigation indicates that the difficulties to bring about a paradigm shift in the production of urban space in the city still remain. The data show the fail in application of the main urban instruments intended to guarantee the social function of property and the difficulty in protecting the built environment, prioritizing the recovery of old buildings before encouraging the construction of new ones. The importance in understanding the period of study is the possibility to prevent and correct such distortions between theory and what is actually done in the city.

The aim of this work was to evaluate hydrogen, ethanol and organic acids productions from several substrate, including, agribusiness byproducts, such as cheese whey, hydrolyzed cellulose and crude glycerol, and simple substrates, such as glucose and xylose. Three continuous reactors were operated. A thermophilic Anaerobic Fluidized Bed Reactor (AFBR), denominated R1, was operated to evaluate hydrogen production from hydrolyzed cellulose. The substrate concentration was 2000mg.L-1 different Hydraulic Retention Times (HRT) ranging from 24 to 6h. Another thermophilic RALF (R2) was used in order to evaluate xylose and glucose co-fermentation to produce hydrogen and ethanol. R2 was operated with HRT starting in 16 h and decreased to 1 h. The substrates concentration was 2000mg.L-1 of each carbohydrate. Hydrogen and propionic acids production was evaluated in Expanded Granular Sludge Bed (ESGB) reactor, operating with Cheese Whey (CW) and Crude Glycerol (CG) co-fermentation in several ratios: 5:1, 5:2, 5:3, 5:4 and 5:5 (m/m) and decreasing HRT from 8 to 0.5h. For R1, maximum yield was 1.1 mol H2.mol-1 glucose, obtained in HRT of 8h. In R2, the consumption of both substrates was verified. However, glucose consumption was higher than xylose. Maximum hydrogen yield, 0,401 mol H2 mol-1 glucose equivalent was achieved in HRT of 16h. Maximum ethanol yield, 0,25mol EtOH.mol- 1glicoseequivalent, occurred in 0.5h HRT. The EGSB reactor maximum hydrogen yield, 0,120 mmol.g-1DQO, was obtained using a 5:1 CW/RG ratio and HRT of 8h. Maximum propionic acid, 0,99g.g-1substrate, was also verified in HRT of 8h, however, with a 5:3 CW/CG ratio. At the end of the work it was made comparison of three reactors. Toward the hydrogen yield the greatest result was obtained by R1 with the value of 2,02 mmolH2.g-1DQO applied, this result occurred in HRT of 8h. In relation to energy efficiency the highest value was observed in R2, 47kJ.h-1.L-1, obtained in HRT of 0,5h.

Among the various human activities, it is possible to observe the presence and the use of technologies in different situations of daily life, such as at work, in schools, at family times and leisure (SANTOS, 2013, MIRANDA, 2013, REIS, 2010). However, there is a shortage of research on CALL (Computer Assisted Language Learning), technology and teaching and learning of Foreign Languages (REIS, 2010). Based on this scenario and on government initiatives, institutions such as UNESCO and universities that develop research on technology in several areas, we propose the development of this work that aims to discuss the publications in national academic journals, classified with QUALIS A (AI and A2) in Language/ Linguistics area. Our analysis comprehends the years 2010-2014. These publications are evaluated by the Coordination for the Improvement of Higher Education Personnel (CAPES), recognized as a reliable reference by the researchers in identifying national journals (BONINI, 2004). It is, therefore, a study that selects research papers from specific journals as the particular objects being examined, characterizing an instrumental case study, as proposed Stake (1994). From these publications, we analyze the concepts of language, technology, and possible methodologies used, encompassing also the results, limitations and some of the referrals found in order to understand at what stage the research nationally published in the area is. Through data collection and analysis, we identified those publications that have online digital editions of free access and at the same time bring teaching subjects and foreign language learning, CALL and technology as theme in their published papers. Based on the results, we have noticed the incipience of studies in the area, according to the literature in our field of research. Besides, we could verify the presence of various objects that compose the covered studies, the different impacts of technology in language teaching (LT), the need of technological knowledge by the teachers, factors that may be addressed in other investigations, once we experience a national context that seems to require more academic disclosure about this theme.

The great dilemma involving solid waste is related to the increase of its generation as well as with the adequate management of its collection, transportation, processing and final disposal, in such a way as to minimize related environmental and urban impacts. Such dilemma has been consuming high levels of human, technological and financial resources, granting the wastes a significant role in the urban sanitation systems. Thus, Brazil has created, by means of Law 12,305, dated as of August 2nd, 2010, the National Policy of Solid Wastes (PNRS) pursuing the systematization of the waste management in the country holding liable all the parties involved in the life cycle of goods. Among the duties contained therein, the PNRS requires the City Halls to prepare a Municipal Plan for Integrated Management of Solid Wastes, which shall present the minimum content to be implemented in this regard. In this way, this paperwork has the purpose to review the Municipal Plan for Integrated Management of Solid Wastes of the City Ourinhos/SP (PGIRSO) in light of the requirements made by the PNRS and to compare the propositions of such plan with the actions so far taken by the City Hall of Ourinhos/SP. It is concluded that, although the PGIRSO provides the minimum content to implement improvements in the wastes management, it has not been put into force, turning it into a simple bureaucracy with no enforcement related to the social environmental quality of the municipality.

The nonabelian tensor square GG of a group G was introduced by R. K. Dennis [8] in a search for new homology functors having a close relationship to K-theory and it is based on the work of C. Miller [14]. Subsequently R. Brown and J.-L. Loday [6] discovered a topological significance for the tensor square, namely, that the third homotopy group of the suspension of an Eilenberg MacLane space K(G; 1) satisfies _3 ��SK(G; 1) _ _= ker(_1), where _1 : GG ! G is the “comutator homomorphism”: _1(gh) = [g; h] = ghg��1h��1, 8g; h 2 G. They also defined the tensor product GH of two distinct groups acting “compatibly” on each other and showed that it arose in a certain “universal crossed square”. The main purpose of this work is to present the first properties of the nonabelian tensor product of groups and its applications in homotopy theory.

Wastewater stabilization ponds are an efficient method of decomposition organic matter in sewage treatment. Both biotic factors such as abiotic act in the ponds. Cyanobacteria are one of biotic factors of great importance to the process of sewage purification. Lot of nutrients can can result in high density cyanobacteria, characterized as eutrophication. These can release cyanotoxins that can harm health human and animal when in contact with them. Physical and chemical parameters are associated with both the presence of cyanobacteria and with the quality of the receiving body and allows evaluating compliance or not the standards required by legislation. Correlate the cyanobacteria density with the physical and chemical parameters and evaluate the receiving body in relation to the released effluent, were the objectives of this work. Quantitative and qualitative analysis of cyanobacteria were realized, and analyzes of the physico-chemical parameters according to Hach manual, and statistical analysis (regression analysis). The phosphorus and nitrogen analyzes have values close to those found in the literature. But phosphorus values downstream demonstrate inadequacy with the rules. The temperature in the pond is higher than the river, characterized by biochemical reactions that take place in this environment. The dissolved oxygen concentration was within the standards and remained in relation to previous studies. The pH and turbidity also attended the law. It has been found through mathematical model, which was thermal stratification in most months in the pond, with the pond in complete mixing in only four months. Statistical analysis showed a positive correlation between cyanobacteria and total nitrogen concentration, but a negative correlation with the effluent temperature. About the cyanobacteria in the pond the main genera found were Merismopedia, Oscillatoria and Pseudanabaena and in the river both upstream as downstream were Microcystis, Pseudanabaena and Limnothrix, indicating the toxic potential of these individuals in the water. The cyanobacteria values in the river downstream mainly, exceeded the value limit of the legislation. In general, some parameters exceeded the limits, but not damaged strongly the quality of the receiving body.

The lightweight concrete for structural purposes is a material that has great potential for application in various construction areas. Its main feature is the reduced density compared to conventional concrete. This characteristic is a great advantage, since one of the main shortcomings of conventional concrete is its heavy weight. Thus there is a reduction in foundation loads, reduction in moving cost due to smaller weight, low consumption cost of cement and, in some cases, improved thermal and acoustic performance. However, despite the great potential application of lightweight concrete, there is a lack of studies regarding the design criteria of elements made of this material type. The lightweight concretes have different strength properties when compared to conventional concrete, thus require special design criteria. As there is no specific Brazilian standard, the design is taken to be similar to the design principles of conventional concrete. In this context, the present study aims to evaluate design criteria for lightweight concrete elements in compression, shear and bending available in national and international standardization and specific technical literature. The study includes both the analysis of the design criteria for the Ultimate Limit State (ULS) and for checking the Limit State Service (LLS). Finally, cases are compared assessing beams, slabs and walls on four different types of lightweight concrete, taking into account factors such as material consumption, cost, weight and cement consumption.
Obras humanas e exigências naturais : a significação do homem no seio da natureza em Gabriel Tarde e Henri Bergson

This thesis analyses the affinities between Gabriel Tarde's and Henri Bergson's philosophies of nature, focusing on their ideas about the man’s meaning, place and role among the works of nature. I will draw from a double shared postulate : Firstly the admission that a nature, which is creative, fulfills well-defined requirements on the act of creation. Throughout the entire nature we will find an effort of creation operating, which is the source of every one of its products, from matter to man. Secondly the evidence that these products extend the requirements in which they find their purpose or reason of existence with more or less success. Once having discriminated the series of beings which emerges from that great enterprise of creation, Tarde and Bergson locate the man at its crown. This man will be described at the same time as one of its products tied to all that forego his dawn and, as an exceptional one, the product in which will be possible for nature to find a solution to its primordial requirements of creation in an exceptional successful way. Nevertheless this man emerged from the general movement of nature, and by prolonging requirements that are preanthropological, will not be made an immediately absolute success only by the exercise of his freedom, sociability and inventiveness. It will be required the action of exceptional individuals who, dragging humanity by their example, will solve the contradictions that nature's inventive genius just relatively evaded. These individualities will be the mystics that accomplish an analogous role in both Tarde's and Bergson's works. Yet, I will carefully demonstrate that despite these affinities we are not allowed to state a full parallelism between Tardian and Bergsonian developments. According to Tarde the effort that we find throughout nature is an effort of progressive harmonization which seeks to place in agreement one pulsive multiplicity that makes background to what is regular in the universe. According to Bergson it consists on an effort to introduce indeterminacy in the universe of necessity, work achieved by the evolution of the living world that creates organisms whose actions will fight against the inertia of matter.To the former, nature appears as a great compositional plan in which matter, life and man figures as stages in a process that leads to progressively comprehensive harmonies. To the latter, a cosmology which deals with the integration between the cosmos strata is inseparable from a philosophy of life and even from a sui generis biological transfomism. Instead of well-delimited stages, Bergson presents life and matter as tendencies that contradict themselves, from whose clash results the whole organized world and, inside its limits, the humankind as one of the solutions that life found when it has converted the matter, obstacle at first, to instrument.

This work has as objective to develop the basic concepts of Probability in 9th grade classes of elementary public school in the countryside of São Paulo state. In this regard, was used Mathematical Magic in order to make teaching more pleasant and meaningful, and, concurrentily we also remained the use of pedagogical instrument problem-solving techniques to the development of these activities. The theme was chosen because the fact of being little explored and worked in basic education, even though presenting applications in many areas and in everyday life. The proposals magic involved simple probability situations and practices, and search for the concepts of the tackle issue and instigate creativity, and critical thinking of learners. Thus, the proposed activities improved the mathematical knowledge of learners and developed a different dynamic, providing a greater involvement in class and consequentily providing enhancements on student performance.

Motivated behaviors may share common reward mechanisms and crosssensitization. The objective of the present study was to find out if history of sodium depletion, which sensitises sodium appetite, also sensitizes sugar intake rat. Sodium appetite was induced by two treatments that raise the production of angiotensin II, diuretic furosemide combined with 24 hours of removal of ambient sodium or furosemide combined with low dose of angiotensin converting enzyme inhibitor captopril (Furo/Cap); and it was blocked by NMDA antagonist (MK-801). Each treatment was repeated three to fours times with an interval of 4 or 7 days between two repetitions. About 7 days after the last repetition, sucrose-naïve animals entered a first 2-h sucrose test under hydrated and fed (need-free) condition. The sucrose test was repeated once a day for a total of five consecutive days. Animals with history of either treatment that produced sodium depletion ingested more 10% sucrose in the sucrose test than control animals, which were never sodium depleted. The effect was stronger in the first tests for sucrose, after that groups ingested similar amounts of sucrose after the second sucrose test. Repeated intracellular dehydration (gavage of 2 M NaCl), instead of sodium depletion, was ineffective to alter the later sucrose intake test. Systemic administration of MK-801, an N-methyl-D-aspartate (NMDA) receptor antagonist, combined with Furo/Cap prevented the enhancement observed in 10% sucrose intake. The results suggest that 1) history of dehydration, particularly that involving production of angiotensin II, sensitizes sugar consumption in sucrosenaïve animals, 2) sensitization of sugar consumption depends on plastic events mediated by NMDA receptors.

This study aimed to answer the following research question: how students in good yield in the context SIMAVE mobilize semiotic representation registers on issues with algebraic content? The method chosen for this research was qualitative, case study technique. The uniqueness of this study is because the teacher-researcher teach math classes for students in the ninth year of primary school, subject participants, since the sixth grade. On the other hand, our students belong to a school context that has shown good results in the external evaluation system of Minas Gerais, since 2009. We developed and applied a test with students, composed of eight items with four alternatives each. In the resolutions ask the justification of reasoning as a means of access to the written production of our students. The quantitative performance of students revealed to us that our students use what they learn in math classes to develop into effective strategists in obtaining the correct alternative. In the qualitative performance, how the semiotic representation registers were mobilized is directly linked to the role played by this teacher-researcher in the classroom, that is, the written record as a way to express the reasoning is treated in our classes as part fundamental development of mathematics student activities. One of the research results showed that skills SIMAVE assessment matrix to identify the relationship between the algebraic and geometric representations of a first-degree equations system is necessary and sufficient to succeed in resolving issues of this evaluation. However, the written records of our students showed that this ability is insufficient when there is need to link the internal concepts to visual elements of the graph as the slope of the line in the Cartesian plane, for example, as a necessary element to the equation of the composition.

The Early Childhood Education, Basic Education first step is to be essential in a child's life 0-5 years old. The Law of Directives and Bases of National Education - LDBEN 9.394 / 96 recommends that this stage of education should be afforded activities that promote the integral development of children in their respective aspects: physical, psychological, intellectual and social, complemented by action and Family the community. Moreover, this is a step that proved quite favorable to the inclusion of students with disabilities in ordinary classrooms. Thus, the teacher assumes a role of great importance, since their practice can contribute to the effectiveness of the inclusion of these children in the education sector process. However, as it is still in its infancy the number of jobs focused productions in the inclusion of disabled students in kindergarten, some questions guided this study: What is the vision of early childhood education teachers across the inclusion of students with disabilities included in their classes? How to give their teaching on the inclusive context? To what extent these practices can be considered inclusive? From them the objectives of the study were defined, and the general: Know what they think the public school teachers of early childhood education on the inclusion of students with disabilities in regular education context and the specific: Identify, through reports teachers, how they are giving their teaching practices with students with disabilities in inclusive context. The study included 8 Education teachers belonging to the municipal public schools in a mid-sized city of the state of. The instrument used for data collection was a semi-structured interview guide containing 15 questions. Data analysis has been done by grouping issues, because of its proximity, in themes that resulted in 9 themes and sub-themes 2. The results showed that the pedagogical practices of teachers are crucial to ensure the full development of children in kindergarten and the consolidation of school inclusion in this stage of education.

The main aim of this work is to study a class of real vector elds de ned on a torus, where the concepts of global hypoellipticity, global C1 solvability and reduction to its normal form are equivalents. We also study a family of commuting vector fields that can be converted into a family of constant vector fields provided that there is one of them which its transpose operator is given by a hypoelliptic operator. We also provide some applications on the global hypoellipticity property for a class of sublaplaceans. This work was based on articles [11] and [12] from Gerson Petronilho.

Brazil is the largest producer of cane sugar and the largest producer and exporter of sugar being the state of São Paulo the responsible for over 60% of the national production of sugar, and the region is where is located the city of São Carlos is main producer region of Brazil, this fact becomes a motivation for this project. The crystallization process is the most important in the production of sugar and responsible for the quality of the final product. This work deals with the modeling and simulation of this process through three different approaches: the ideal crystallizer (MSMPR), the integrated sugar production without description of crystals, approach called "gray-box", and the industrial crystallizer. The models were developed in the software EMSO. The EMSO is a program developed in Brazil and has a great advantage compared to other programs, it's a free program, without the need to license purchase. By allowing full access to the developed mathematical models, facilitates the insertion of new models such as the present study about crystallization and allow the improvement of existing models, allowing also the development of specific software libraries. The first held approach, MSMPR, aims to introduce a protocol currents description containing solids and the crystallization process in the EMSO, for in his library there is no model that describes the crystallization or even containing solids, unlike other widely used commercial programs for the simulation of processes such as Aspen Plus, having a model MSMPR. So when performing this first approach, the EMSO can match other programs in relation to the crystallization process. The mass averaged crystal size (MA) obtained with the parameters set as default, L43 = 1.18 mm is much greater than the expected value L43 = 0.5 to 0.55 mm, but with the variation of the kinetic parameters can be obtained results within the desired range . The second approach is a simplified model called "gray-box" in order to facilitate the paying in of crystallization models with models referring to others process. The sugar production obtained in this model was similar than that reported in the literature, but the model can be useful in paying in of process models which constitute a industrial plant. The third and most important approach corresponds to the model of an industrial crystalliser with intent to represent real process of sugar production using data from literature. The discussion was carried out on the variables: temperature, brix, crystal mass and MA. The variations of temperature and brix relative to time obtained are consistent with each step of the process. The crystal mass produced in the simulation is approximately 50% lower than that found in the literature, whereas the MA is also below, but achieves excellent results in the change of the kinetic parameters. The final results obtained in the simulations do not coincide with the expected results, but the easy access to developed models makes these models a good instrument to parameters analysis, reaching with some changes in the kinetic parameters, in satisfactory results that well represent the real process.

This study aimed to produce propionic acid, 1,3-propanediol and hydrogen in anaerobic fluidized bed reactor with grounded tire as support material for immobilization of biomass. The experiment took place during 278 days in six distinct phases distributed according to the hydraulic retention time (HRT), which ranged between 8 and 0.5 h. The reactor was maintained at mesophilic conditions (30 ° C) with controlled pH between 4.5 and 5.5 and crude glycerol as carbon source at a concentration of 5 g L-1. The inoculum used in the experiment was derived from the processing of poultry slaughterhouse wastewater station. The results show that the consumption of substrate conversion reached the highest value (89.8 %) in HRT of 6 hours. The biogas produced was composed of H2 and CO2 and the greatest recorded content of H2 has been reached (81.2%) in HRT of 4 hours. The principal soluble metabolite produced were propionic acid and 1,3-propanediol, with maximum yields of 1,77 and 0,82 mol.molglicerol -1, respectively. Both maximum yields were achieved in HRT of 8 h. At all stages of this work occurred predominantly propionic acid, with maximum molar percentage (96,9 %) achieved in HRT of 0,5 h. The second predominant metabolite obtained was 1,3- propanediol, achieving greater molar percentage (29.4%) in HRT of 6 hours.
