No presente trabalho foram analisadas as distribuições de probabilidade teórica Normal, Log-Normal, Exponencial, Gama e Weibull, para estimar as vazões máximas e mínimas anuais para o rio Paraguai, utilizando dados de uma estação fluviométrica localizado na cidade de Cáceres-MT. Os testes de Kolmogorov-Smirnov e Qui-Quadrado foram utilizados para verificar a aderência das probabilidades estimadas às freqüências observadas. A série utilizada compreende vazões máximas e mínimas anuais dos anos de 1966 a 2003, excluindo- se dados com falhas. Verificou-se que o melhor ajuste dos valores anuais de vazão máximas e mínimas são referentes a distribuição Gama e Weibull, respectivamente, conforme demonstrado pelo teste de Kolmogorov-Smirnov. Palavras-chave: Previsão de Vazão, teste de aderência.

Nesta obra pretende-se estudar as duas formas rituais da liturgia romana, comparando-as e procurando entender os motivos do cisma, ao mesmo tempo em que se pretende abarcar as ações do atual pontífice e as reações no mundo católico e fora dele. Para tanto, usar-se-á como fonte o Missal tridentino de 1570 e o novo Ordo Missæ de Paulo VI de 1969, bem como os catecismos formulados após os Concílios de Trento (1545-1563) e o Vaticano II (1962-1965), tendo por objetivo comparar suas notificações sobre o culto católico e seu significado. Durante o processo de análise tem-se a intenção de vislumbrar o impacto das mudanças no seio da Igreja, pois constata-se uma espécie de endurecimento no final do pontificado de João Paulo II, com a promulgação de documentos litúrgicos que tendem a criar empecilhos para possíveis abusos durante a missa (Ecclesia de Eucharistia, 2003) - há a retomada e destaque do sentido sacrificial do culto católico e uma série de recomendações impostas pela Congregação do Culto Divino para celebração da missa (Redemptionis Sacramentum, 2004). Fato é que, quarenta anos após o mencionado Concílio Vaticano II e quase quatro décadas de utilização do novo rito da missa, é rara qualquer menção específica na historiografia recente da Igreja sobre o andamento de tal tema. A maioria dos livros de história da Igreja que traça um levantamento de fatos até o Vaticano II, apresentam-no como uma espécie de revolução interna da estrutura eclesiástica sem, contudo, aprofundar o tema ou mostrar as crises na Igreja decorrentes deste.

A escola no Brasil vem enfrentando o aparecimento de uma série de dilemas, frutos das mudanças sociais ocorridas nos últimos tempos, que terminam por sobrecarregar os professores. Diante desse cenário, boa parte dos professores que estão na ativa almeja a aposentadoria, enquanto outros, já aposentados, estão voltando às escolas. É a partir dessa aparente incoerência que Vanessa Ribeiro Andreto Meira e Yoshie Ussami Ferrari Leite refletem sobre os motivos que levam um professor aposentado a voltar a uma escola que vem assumindo novos papéis para os quais muitas vezes ainda não está preparada. Elas observam que inúmeras novas funções, como o ensino de conceitos básicos para a convivência em sociedade, antes atribuição das famílias, foram simplesmente delegadas ao professor, quem consequência passaram a ter mais dificuldade para definir prioridades. O estudo toma como base uma pesquisa realizada com professoras aposentadas que atuam na rede de ensino municipal de duas cidades do sudoeste do estado de São Paulo - Presidente Prudente e Presidente Bernardes -, e propõe análises sobre os desafios postos à escola pública, levantando questões relativas à aposentadoria do professor no Brasil e discutindo os ciclos de vida e de carreira docentes

This paper analyses how innovations and educational reforms affect curricular construction at public schools. It aims at reflecting if the Curricular Proposal for the state of São Paulo preserves the autonomy and identity of schools, if it respects their pedagogical political project, without attempting to homogenize them; how it changes every‐day school life, teacher’s practices, interpersonal relationships and power relations. We depart from the presupposition that this proposal adopts principles of the educational reforms started in the middle of the 90s, such as: adoption of national guidelines; introduction of market mechanisms, generating the fragility of teachers’ representation and their de‐ professionalization; relativity of the State’s role; stimuli to partnerships between public and private institutions in the fields of administration, allocation of financial resources for teaching    and implementation of external evaluating systems. At the same time, official discourse highlights decentralization, democratic administration, community participation. Some of these principles are recurrent in curriculum reforms: emphasis on the knowledge society, pedagogy of competencies and of learning to learn. In this way, we understand that the proposal aims at homogenizing school knowledge and curriculum practices, representing the notion of curriculum as product. We consider that the novelty and relevance of implemented measures demand further research, and that will be implemented by the author in 2010.

The main impact of hearing loss, in childhood, is the difficult to speech perception. The hearing aids and the cochlear implant are resources used to decrease a result of hearing loss. After the adjustment of these resources, with the therapeutic process, is possible that children with profound hearing impairment develop their hearing abilities, so they will have possibilities to notice phonetic and phonological characteristics of the language. Different speech perception procedures investigate which phonetic and phonological characteristics of the speech segment can be noticed by children with hearing loss. This study aims at analyzing the audiology profile and the speech perception in deaf children and adolescent.

This paper concentrates on the analysis of how the typical voices of History are manifested, which is achieved by the aesthetics of the contemporary Portuguese narrative, as it aims at the same time the reflexion and the reformulation of the Lusitanian cultural imaginary in the course of O retorno, a novel by Dulce Maria Cardoso. The hypothesis that arises is that the trajectory of Rui’s individual experience, as wells as the other’s characters “retornados” looking for identity, is parallel to the proposed revision of the Portuguese nation collective cultural imaginary in the decolonization context, after the 25th April Revolution. It is its objective to investigate how the historical processes concerned to the concepts of exile and uprooting, displacement and belonging (BAUMAN, 2005) are fictionalized in the novel, seen as motes for Rui’s pursuit for identity and for the revision of the Portuguese Destiny theme

The use of rainwater for non-potable purposes generates a reduction in the consumption of treated water, however, this reduction is not observed in the generation of wastewater, as this is independent of the water source. In Brazil, the pricing on the services of collection and treatment of sewage, in general, is based on the coefficient of return of the sewage disposal system, which has a relation sewer / water proportional to the consumption of treated water measured at the consumer unit. The use of rainwater originating from utilization systems infer on the coefficient, underestimating the volume of wastewater generated. Therefore, this study presents a methodology for setting the coefficient of return. Different roof areas, reservoir volumes and rates of water consumption situations were simulated. The behavior of adjustment of the coefficient of return were also analyzed for the average area per capita roof (m² / inhabitant) of Rio Claro - SP. As a result, it can be seen that the adjustment of the coefficient of return is directly proportional to the increase of the roof areas and the volumes of reservoirs, and inversely proportional to the total water demand. The corrected coefficient of return showed the minimum value of 0.83 and a maximum value of 1.45, this variation corresponds to the maximum ratio between the demands of total water and rainwater, since the exploitation of rain water should be used only for non-potable uses, according to NBR 15527 / 07. To the municipality of Rio Claro - SP was noted an adjustment of the coefficient of return ranging from 0.99 to 6.61

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy
