This work describes the steps for converting a linear paper-and-pencil English proficiency test for academic purposes, composed with multiple choice items that are administered following the admissible probability measurement procedure (Shuford Jr et al., 1966), adopted by the graduate program of Institute of Mathematical Sciences and Computing of University of São Paulo (ICMCUSP), Brazil, to a computerized adaptive test (CAT) based on an item response theory model (IRT). Despite the Institute recognizes reliable international English-language exams for academic purposes and non-native speakers, as TOEFL (Test of English as a Foreign Language), IELTS (International English Language Testing System) and CPE (Cambridge English: Proficiency), for instance, it is inconsistent that public universities in Brazil require them as certification because of the cost of approximately US$ 200.00 to US$ 300.00 per exam. The software TAI-PI (computerized adaptive test for English proficiency) was implemented in Java language, used SQLite as database engine, and it shall be offered free of charge for English proficiency assessment of the graduate students from October 2013. The statistical methodology employed for TAI-PI construction was defined considering the history and the aims of the evaluation and adopted the Samejima's graded response model (Samejima, 1969), the Kullback-Leibler information criterion for item selection, the expected a posteriori Bayesian estimation for latent trait (Baker, 2001) and shadow test approach (Van der Linden & Pashley, 2010) for test constraints (content and size of the test, for example). A description of the test design, the employed statistical methods, study results of a real application of TAI-PI to graduate students are presented in this work and the validation studies of the new methodology for pass/fail classi cation, highlighting the good quality of the new evaluation system and examination of improvement with the use of the methods of IRT and CAT.

In the context of Construction, the constructive structural system is responsable for considerable parcel of the construction performance after its occupation. First, this research uses a theoretical boarding within a bibliographical revision about concepts of industrialized construction, approaching the current technician scene in Brazil, and confronting some of the main industrialized technologies available today in the segment of construction. Then, it is tried to demonstrated the technique viability of constructive and structural steel system through the development of a module that could be adjust to diferent archetypes of constructions. Such a way, it was opted to the choice of an existing building in the Federal University of São Carlos (UFSCar), called building of theoretical class rooms 7 (AT7), adapting its educational demand into a system modular in steel. For such boarding,the elaboration of solutions techniques, in a flexible and adaptable way to the initial projetual conception was necessary, contemplating not only space geometry in respect to its structure, but also considering closings systems, installations and logistic, inside industrialized construction thematic. As result, a viable technically modulation was elaborated, considering dimensional, structural and logistic points, so it could be applied or adjusted according to some situations of project, inside constructive and structural types boarded in this study. In this manner, the research presents practical character, therefore it is motivated by the necessity of approaching relative real problems to the projetual conception, supplying and fomenting techniques choices about industrialized systems, cooperating in the spreading of the concept of Industrialization in the technician scene.

The study conducted examined the sediment removal behavior for a lawn channel built full-scale, 100 m in length, slope of 2% and wide base of 0.7 m in the Federal University of São Car them, San Carlos - SP. For this analysis, we simulated runoff for three volumes of downloads 5; 7; 10 m³, represented each with their respective hydrograph and blade height by passing the flood wave. These flows were mixed with the particulate material produced from the local ground of the campus area, sieved to smaller than 75 micron, which is used for varying the initial concentration for tests. The experimental data were fit to a model first order decay, Meira optimum slug flow in through non-linear regression using decay kinetic parameters (k d) and equilibrium concentration (C *). Fractions removed and the mathematical adjustment were evaluated and executed for each single event along the length of the lawn channel monitored in 26 positions. The peak of the hydrograph was investigated in the range of 11 ± 2 L / s and time base (tb) determined at the unloading point on the channel varied from 15, 25 and 35 minutes. The transit time in the channel (tT) was approximately 10.5 ± 2.5 m, corresponding to 0.14 ± speed 0,02 m / s. The maximum efficiency of particulate matter removing over the lawn channel length ranged from 47 to 81% in 20-90 m positions. Whereas all concentrations of investigates, it was found that for 15 minutes tB, the average maximum efficiencies were on the order of 64 ± 3% to ± 26 position of 31 m. TB to 25 minutes the average maximum were of the order of 73 ± 3% to 59 ± 24 m positions. Finally, for 35 minutes tB the average maximum efficiencies were obtained in the range of 65 ± 3% in the 73 ± 15 m positions. The ratio tb / tT correlated 0.98 with the position of maximum efficiency. The maximum removal positions are related to the decay constant (Kd). It was found that 70% of the values of the decay constant (Kd) is between 0.005 and 0.015 s-1, and to disregard the hydrograph represented by tB 15 minutes, 90% of the data is contained in it Halftone 0.005 Kd ≤ ≤ 0.015 s-1 and 85% in the range 0.007 ≤ 0.012 ≤ Kd s-1. It was identified direct and proportional relation of the equilibrium concentration (C *) and initial concentration (Co).

The corticotropin-releasing factor (CRF) is involved in behavioral and physiological responses to emotional stress through its action in several limbic structures, including the bed nucleus of the stria terminalis (BNST). Nevertheless, the role of CRF1 and CRF2 receptors in the BNST in autonomic adjustments during aversive threat is unknown. Therefore, in the present study we investigated the involvement of CRF receptors within the BNST in autonomic responses evoked by the acute restraint stress in rats. For this, we evaluated the effects of bilateral treatment of the BNST with selective agonists and antagonists of either CRF1 or CRF2 receptors in the arterial pressure and heart rate increase and the decrease in tail skin temperature induced by restraint stress. Microinjection of the selective CRF1 receptor antagonist CP376395 into the BNST reduced the pressor and tachycardiac responses caused by restraint. Conversely, BNST treatment with the selective CRF1 receptor agonist CRF increased restraint-evoked arterial pressure and HR responses and reduced the fall in tail skin temperature response. All effects of CRF were inhibited by local BNST pretreatment with CP376395. The selective CRF2 receptor antagonist antisauvagine-30 reduced the arterial pressure increase and the fall in tail skin temperature. The selective CRF2 receptor agonist urocortin-3 increased restraint-evoked pressor and tachycardiac responses and reduced the drop in cutaneous temperature. All effects of urocortin-3 were abolished by local BNST pretreatment with antisauvagine-30. These findings indicate an involvement of both CRF1 and CRF2 receptors in the BNST in autonomic adjustments during emotional stress.

The objective of this study is to analyze the understanding that teachers serving students with intellectual disabilities in a specialized institution have on the teaching of reading and writing. National theses and dissertations of studies have shown that teaching reading and writing is possible for people with intellectual disabilities based on different theoretical perspectives. The research is qualitative / quantitative exploratory type, the instrument used was a semi-structured interview. It was conducted in four APAEs located in the state of São Paulo, being interviewed a total of 11 teachers who worked with the teaching of students with intellectual disabilities for more than three years. The categories of analysis of the interviews were defined from the content analysis proposed by Bardin. In the data analysis it observed aspects such difficulty by the teacher to define intellectual disability and teaching and learning theoretical confusion - Methodological about the process of reading and writing learning and mostly practices decontextualized teaching and without reflection. The study points out the need to review teacher training, updating and further clarification on this matter and the need for greater interaction between researchers and professionals, thus enabling the socialization practices.

The decrease of regulate the estrogen production that occurs at menopause is typically followed by increase of several deleterious changes in the skeletal muscle system. Menopause is mimicked experimentally by a technique called ovariectomy. The ovariectomy produces increased total body mass, changes in body composition and lipid profile, reduction in skeletal muscle (sarcopenia) and bone mineral mass (osteopenia). Mitochondria play a crucial role in a myriad of cellular processes including oxidative phosphorylation, biosynthetic pathways and programming of cell death. Alteration of mitochondrial biogenesis markers in ovariectomized rats and the effects of resistance training (RT) and estrogen replacement (RE) are unclear. Purpose: This study aimed to investigate the effects of Ovariectomy (Ovx), RT and ER on markers of mitochondrial biogenesis and protein expression related to oxidative capacity in the rat gastrocnemius pool. Methods: ER was performed using Silastic® capsules. During the 12-week RT, the animals climbed a ladder with weights attached to their tails. RT began simultaneously for all experimental groups. Gene expression was analysed by RT-PCR, and protein content was determined by western blotting. Results: The estrogen deficiency associated with Ovx decreased the gene expression of the mitochondrial biogenesis markers PGC-1α (~73%), NRF-1 (~44%), and TFAM (~53%) (p<0.05) and decreased the protein expression of phosphorylated AMPK, CREB and AKT, which are related to oxidative capacity, compared to the Sham-Sed group. RT increased PGC- 1α (~59%) and TFAM (~48%) expression compared to the Ovx-Sed group. The combination of RT and ER was superior to the Ovx-Sed and Ovx-RT treatments regarding the gastrocnemius muscle. Conclusions: This study showed that ovaries removal affects transcription factors that regulate mitochondrial biogenesis in skeletal muscle. According to our results and evidence from the literature, and estradiol levels of exercise appear to play an important role in the protection of mitochondrial dysfunction in skeletal muscle of rats.

The present paper searches into the performance of teaching supervisors in the special education from special classes to resource rooms. Discusses the supervisory action by analyzing the gathered information collected in data forms visit by the teaching supervisors in special classes and in resources rooms of two schools which ones count on those services of educational specialized support (SAPE-s) in network state schools inner São Paulo, at the lapse of time when the change from the special classes to the resource rooms happened (2000-2013) and searches to know, through semi-structured interviews with specialized teachers and teaching supervisors, how do they position themselves in relation to the inclusion of students classified as Intellectually Disabilited ( DI), to the ways of forwarding students to specialized treatment and teaching supervisor's performance in special education. Through a literature search, based on the Historical-Critical Pedagogy, we conducted a historical of the teaching supervision, placing its performance in the history of special education, since the appearence of special classes up to the inclusion movement from the Salamanca Statement and problematize a reality permeated by contradictions in that inclusive education is understood as a justification to classify a large number of students as intellectually disabilited (ID). The analysis of the data forms visit, interviews, legal documents and standards that rule the network state special education system allowed us to understand that discrimination and labeling of students who present learning difficulties are factors that embarasses the student classified as DI to enjoy the right to education, to which everyone, without exception, should enjoy.

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.

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.
