Aconselhamentos de auto-ajuda: um caso de captação do gênero proverbial

Neste trabalho, que está baseado nos princípios da Análise do Discurso francesa, seguindo especialmente o pensamento de Maingueneau, analisamos a relação que há entre o discurso de auto-ajuda e os provérbios, o que nos permitiu verificar que o discurso em questão pode ser considerado como um caso de captação do gênero proverbial.

A modalidade na literatura de auto-ajuda

Neste trabalho, baseado nos princípios da Análise do Discurso francesa, seguindo especialmente o pensamento de Maingueneau (1998), analisamos a modalidade na literatura de auto-ajuda, o que nos permitiu verificar que a manifestação da certeza é um dos traços semânticos desse discurso.

Avaliação do comportamento reológico na retração plástica e na fissuração de argamassas de concreto auto-adensável

This paper investigated the influence of the amount of superplasticizer and mineral adding - silica fume and basaltic filer - in plastic shrinkage and cracking of self-compacting concrete (SCC) mortars. Initially analysis was performed of the rheological behavior of cement paste and mortars phases of the compositions of SCC. Then the deformations of mortars were measured by the effect of shrinkage and evaluation of cracking. On plastic shrinkage and cracking, the composition with silica fume showed superior results, independent of wind and superplasticizer content, relative to the composition with addition of basalt filler. However, the composition with silica fume showed superior results only in the tests with imposed ventilation at vertical plastic deformation. The rheological behavior affected directly the plastic shrinkage and cracking at early ages, fact confirmed by the analysis of capillary pressures of mortars tested.

Auto-organização e autonomia em Hegel: uma abordagem a partir das linhas fundamentais da filosofia do direito

The German philosopher G.W.F. Hegel (1770-1831) had as one of his thesis in the doctorate the affirmation that philosophy can only be properly taken as a system. He intends with that to point out the identity between thinking and being. This is, for Hegel, the task of philosophy, i. e., to bring together all that was set apart. This position can be recognized in all his works and it is tried here to exemplify it in The Philosophy of Right and in special in the section dedicated to the abstract right. This one is the first moment of the text in question that begins with the statement of the dignity of the person confirmed in the property. The following moments make evident that the formal ones are also results. It becomes clear in this way that the all the moments create together an ongoing organization, disorganization and reorganization. This process reveals the relation as a constitutive element of thinking and being exemplified in the abstract right. Each moment overcomes the preceding one and comes out as a much more complex one. In the case of the abstract right what appears is the realization of a free subject in all that he does as the making of himself.

Desenvolvimento das habilidade de auto-cuidado em crianças com atraso neuropsicomotor

Introduction: The neuropsicomotor development could be negatively affected by several factors occurred in the pre, peri and pos natal period. The early stimulation is implemented by a set of dynamic activities which aim the child development according to the child’s phase. Objective: The purpose of this study was to analyze the functional skills acquisition in the self care area in children with development delay. Participated of this study 9 caregiver of children aged of 0 to 3 years with delay neuropsicomotor. Method: For the data collect was used the self-care area of the Pediatric Evaluation of Disability Inventory (PEDI) in the version adapted for Brazil. The data collect was performed in two different stages, with an interval of 6 months between the collects. The raw score were transformed in continuous score by the Rasch statistics, then was applied the Shapiro-Wilk and t-student test. Results: The participants obtained a signifi cant higher score in the second stage than in the fi rst (p<0,01). Conclusion: The results of the present study suggests that the early stimulation could be an important intervention in the process of self-care skills acquisition in children with neuropsicomotor delay.

Avaliação da auto-suficiência energética em reatores anaeróbios aplicados ao tratamento de resíduos da indústria de produção do etanol

Ethanol, the main automotive biofuel, has its production based on the fermentation of sugars found in biological materials and on the distillation of the alcoholic media formed during the fermentative process. Stillage is the main residue from ethanol production, containing a high organic loading in addition to acidic and corrosive characteristics. Considering the available technologies to treat stillage, we highlight anaerobic digestion, which allows the reduction of the impacts associated to pollutants loading of this effluent and the generation of energy from the methane gas produced in the process. Based on the high treatment efficiency usually associated to the anaerobic process, this work aimed to assess whether anaerobic systems applied to the treatment of stillage are energetically self-sufficient. First we evaluated the energy recovery capacity in an anaerobic reactor applied to the treatment of stillage resulting from corn-to-ethanol processing. The results indicated the great influence that a correct selection of electrical equipment and their respective operating periods have on the net energy balance of the anaerobic treatment. The high energy consumption of the heater would not allow the system to achieve a positive net energy balance – the maximum energy recovery would reach only 0.68% of the consumption. However, the replacement of the mixture equipment would result in energy gains ranging from 8.5 to 967.9% of the consumption. In this work we also assessed the efficiency of methane yields for a few studies and the correlation between some parameters of the anaerobic process. With respect to the methane yield, we noted that mesophilic systems tend to be more advantageous than the thermophilic ones (efficiency of 76.45 ± 22.51% vs. 69.40 ± 30.36%). Considering the study...

Avaliação da auto-suficiência energética de reatores anaeróbios no tratamento de esgoto sanitário e água cinza

The anaerobic treatment of sewage is widely employed in Brazil and it is an appreciated way for the treatment of effluents, helping to reduce the environmental impact in rivers. The methane gas obtained from the process can be applied to improve the energetic efficiency of the system, reducing the amount of waste and the cost of the treatment process. This work presents the net energy balance of anaerobic reactors applied to the treatment of sewage. The analysis was performed considering full-scale and laboratory-scale treatment systems. In laboratory scale, the results from three kinds of systems were compared regarding the biological treatment of greywater. Two of them (UASB7 and UASB12) were anaerobic and the other one was a combined anaerobic-aerobic system (UASB7/SBR6). Greywater methanization (compared to theoretical maximum) was calculated considering 100% removal (g BOD/day), the literature percentage removal and the anionic surfactant presence in the effluentt. For each of these three cases, the efficiencies were, respectively, 16.9%, 43.6% and 51.3% in UASB7 reactor, 25.6%, 50.3% and 59.2% in UASB12 reactor and 30.6%, 61.2% and 71.9% in UASB7/SBR6 reactor. The energetic potential was found to be 4.66x10-4, 7.77x10-4 and 5.12x10-4 kWh/L for the UASB7, UASB12 and UASB7/SBR6 reactors, respectively. The pumping system, the aeration (in the anaerobic-aerobic system) and the temperature controlled heating system were considered to calculate the energetic consumption. However, the third one was not employed since tropical regions like Brazil do not need heating systems and also because of its high energetic consumption. The calculated net energy balance in the reactors was negative in the case of greywater, respectively -0.16, -0.28 and -0.18 kWh/L for the reactors UASB7, UASB12 and UASB7/SRB6. In full scale (ETE Jardim das Flores - Rio Claro, SP), the average energy... (Complete abstract click electronic access below)

Auto-ecologia de Geonoma gamiova Barb. Rodr. (Arecaceae) em mata ombrófila densa montana (Parque Estadual Carlos Botelho, SP)

Geonoma é um dos mais complexos gêneros de palmeiras neotropicais e possui aproximadamente 80 espécies distribuídas nos Neotrópicos. Espécies desse gênero apresentam pequeno a médio porte e são típicas de sub-bosque de florestas em áreas com grande pluviosidade. Este trabalho teve como objetivo analisar a auto-ecologia de Geonoma gamiova em duas escalas espaciais, relacionando sua estrutura populacional entre hábitats (fundo de vale x encosta) e microsítios (local de ocorrência clonal). O trabalho foi realizado no núcleo São Miguel Arcanjo do Parque Estadual Carlos Botelho que possui uma área de 37.794 ha e uma amplitude altitudinal de 50 a 975 metros. A área apresenta relevo de montanhas com vales profundos e morros paralelos e a vegetação presente no Parque é a Floresta Ombrófila Densa. Foram distribuídas 30 parcelas de 5 x 20m em três trilhas no Parque, onde foram quantificados os indivíduos de Geonoma gamiova em três estágios de desenvolvimento e foi caracterizado o hábitat. Foram marcados 42 indivíduos de Geonoma gamiova para avaliar o crescimento vegetativo e sua ecologia reprodutiva, avaliando-se também a estrutura dos microsítios em que esses indivíduos se encontravam. Os indivíduos apresentaram uma distribuição de tamanho populacional em forma de J invertido. Geonoma gamiova foi a segunda palmeira mais abundante na área estudada. O tamanho das moitas foi maior no fundo de vale, porém, os parâmetros mensurados para verificar a estrutura de comunidade, assim como a abundância dos indivíduos de G. gamiova não apresentaram diferença significativa (p > 0,05) entre os hábitats. Não houve nenhuma correlação significativa (p > 0,05) entre o número de estipes por moita e as variáveis microclimáticas e edáficas mensuradas. O crescimento dos estipes, avaliado pelo aumento do número de nós, apresentou diferença significativa, sendo maior.... (Resumo completo, clicar acesso eletrônico abaixo)
