Participação popular ou participação tutelada?: análise do desenvolvimento da Agenda 21 local em Barueri

Esta dissertação discute a questão da participação popular em políticas públicas tendo como base a análise do caso da Agenda 21 local em Barueri. Parte- se da revisão teórica sobre a participação, desde a emergência do tema entre os movimentos sociais na Europa, até a chegada da discussão ao Brasil. A partir desta revisão são tratados aspectos teóricos do clientelismo político, visando contrapor a prática política existente e legitimada com os dilemas da implantação de ações participativas. A investigação foi realizada sob a perspectiva de campo-tema, sendo construída a partir da leitura de narrativas. O que se observa é uma dificuldade em promover mudanças no formato de condução das políticas em Barueri oriunda da incapacidade do governo em mobilizar a população e demonstrar a importância e confiabilidade de práticas participativas. Este trabalho busca demonstrar quais foram as falhas e dilemas deste processo e propõe formas de se avaliar e discutir a implantação da participação popular como nova prática política.

Acúmulo de massa seca e de macronutrientes por plantas de Glycine max e Solanum americanum

A soja é uma das principais culturas agrícolas do Brasil, sendo a sua produtividade muito influenciada pela competição exercida pelas plantas daninhas. Foram realizados dois experimentos em casa de vegetação, em Jaboticabal, SP, objetivando determinar o acúmulo de massa seca, assim como a distribuição e o acúmulo de macronutrientes em plantas de soja, no período de outubro de 2000 a fevereiro de 2001, e de Solanum americanum, no período de janeiro a maio de 1995. As plantas cresceram em vasos com capacidade de 7 litros, preenchidos com areia de rio lavada e peneirada; elas foram irrigadas diariamente com solução nutritiva. Os tratamentos foram representados pelas épocas de amostragem, realizada a intervalos de 14 dias, iniciando-se 21 dias após a emergência (DAE), até 161 DAE para S. americanum e 119 DAE para soja cv. BR-16 (precoce). O ponto de máximo acúmulo teórico de massa seca deu-se aos 104 DAE para a soja (35,0 g por planta) e 143 DAE para S. americanum (179,62 g por planta). da emergência até 49 e 63 DAE, as folhas apresentaram maior participação no acúmulo de massa seca para soja e S. americanum, respectivamente. Após esses períodos, verificou-se, em ambas as espécies, inversão na representatividade das folhas por caules para a espécie daninha e por caules e, posteriormente, por estruturas reprodutivas, para a cultura. A taxa de absorção diária dos macronutrientes atingiu maiores valores entre 69 e 87 DAE para a soja e entre 105 e 119 DAE para a planta daninha. Considerando a média dos valores de pontos de inflexão observados para a cultura da soja, tem-se que aos 75 DAE uma planta de soja acumula teoricamente 23,9 g de massa seca, 564,4 mg de N, 7,1 mg de P, 490,8 mg de K, 487,0 mg de Ca, 156,6 mg de Mg e 36,0 mg de S. Para o mesmo período, uma planta de S. americanum acumula teoricamente 33,75 g de massa seca, 875,96 mg de N, 88,46 mg de P, 983,54 mg de K, 647,60 mg de Ca, 100,93 mg de Mg e 42,15 mg de S.

Processo participativo da população na construção da agenda 21 local:o caso de Parnamirim

One of the agreements assumed at the conference of the United Nations for the Environments and Development which took place in Rio de Janeiro in 1992; through Global Agenda 21, was that the signatory countries would create a national Politics of sustainable development, by means of their national Agenda 21. Demonstrating the relevance of municipal districts and the local communities, during the definitions of new development standards compromised to the transformation of the society, socia1ly and environmentally well-balanced world, it was also agreed on that places under the responsibilities of the municipal districts would promote their own local Agenda 21. We need to point out though that the government has the prerogative and the responsibly of facilitating the population participation process in the construction of national and local Agenda. This made it possible again, to plan the scheming process directly towards the insertion of population participation at the different levels, involving the entire local sectors while establishing a new local partnership through the local municipal government. Thus, we decide to verify the participation of the population in the construction of their local Agenda 21, choosing for the study case Parnamirim municipality from RN. The question which originated the objectives and analysis was formulated on the following terms: Up to which stage was the process of population participation effective in the elaboration of Parnamirims's local Agenda 21? Based on this uneasiness, it was defined as the general objective, the verification of population participation process during the elaboration of Parnamirims's local Agenda 21, aiming at its effectiveness as well as specific objectives; to identify the population representivity, the construction of the local AG 21 in order to identify on which level is the participation based, to verify the strategies used in order to promote the process participation, to identify the motives guiding those involved in the construction of the local Agenda 21. This case study at Parnamirim municipal district demonstrated that there was effective population participation as far as the local Agenda 21 is concerned

Holter electrocardiography in dogs showing doxorubicin-induced dilated cardiomyopathy

O estudo consistiu na identificação precoce da ocorrência de arritmias em cães com cardiomiopatia dilatada experimental induzida pela doxorrubicina (DOX). Utilizaram-se 10 cães adultos, sadios, distribuídos nos grupos A (n=5) e B (n=5). O grupo B recebeu 30mg/m² de DOX, via intravenosa, a cada 21 dias, até a dose cumulativa de 180 ou 240mg/m². No grupo A (controle), administrou-se solução salina 0,9%, via intravenosa, nos mesmos intervalos do grupo B. Ao se evidenciar o quadro de disfunção miocárdica nos cães do grupo B, caracterizado pela fração de encurtamento menor que 20%, aumento da separação septal do ponto E acima de 0,7cm e aumento do índice volumétrico do ventrículo esquerdo ao final da sístole (61,4ml/m²), realizaram-se os eletrocardiogramas por 24 horas. Os resultados demonstraram aumentos de 44,6% e 41,7% nas freqüências cardíacas mínima e média, respectivamente, e presença, com maior freqüência, de arritmias supraventriculares do que ventriculares nos animais do grupo B. Concluiu-se que o Holter é eficaz e demonstra, com precocidade e melhor definição, as alterações da freqüência e do ritmo cardíaco de cães com disfunção miocárdica induzida pela doxorrubicina.

Evaluation of tear production with modified Schirmer tear test-1 during the neonatal period in cats

Objetivou-se avaliar a produção lacrimal, por meio do teste da lágrima de Schirmer-1 modificado (TLS-1m) em gatos neonatos. Outrossim, estabelecer in vitro a existência de correlação entre o TLS e o TLS-1m. Tiras pa-dronizadas para realização do TLS foram partidas ao meio e após a abertura das pálpebras, a produção lacrimal dos neonatos (n=15) foi aferida em ambos os olhos (TLS-1m), diariamente, até o sétimo e aos 14, 21 e 28 dias. Os animais foram pesados diariamente até os 28 dias de idade. Os resultados foram comparados estatisticamente (p<0,05). Durante os primeiros sete dias de avaliação, a média geral obtida pelo TLS-1m foi de 0,76±0,08 mm/minuto. Não se constatou diferença significativa entre os olhos direito e esquerdo, em nenhum dos períodos avaliados (p=1,00). A produção lacrimal elevou-se significativamente, do 14º até o 28º dia, comparativamente aos primeiros sete dias (p<0,05). Observou-se correlação positiva entre parâmetros de maturidade e a produção lacrimal (p<0,0001). A distância entre as linhas de cada tira foi significativa (p<0,0001). Conclui-se que a produção lacrimal no período neonatal em gatos é bem inferior aos valores de referência descritos para adultos e jovens da mesma espécie. Não é possível extrapolar valores obtidos com o TLS-1 modificado para o TLS-1 padrão.

Gestão ambiental na educação: um estudo sobre fatores que afetam o comportamento ambiental de professores do ensino médio, na cidade de Floriano-PI

The present work sets out environmental issues in educational field. The aim of this research was to investigate the factors capable to influence the environmental behavior of the teachers in High school of the public school in Floriano, state of Piaui. For this, the methodology utilized an explanatory and descriptive search like a survey; questionnaires were applied with open and close questions establishing shifts that made up the following aspects; knowledge, behavior, responsibility, participation and trait of the teachers. The statistic techniques to analyze the data were descriptive analysis and analysis of multiple regression. The results reveal that teachers care about the real surrounding problems and believe that the school must develop ambient activities to stir the consciousness, it is important to the environmental improvement of the city. However, the results point out that are developed little activities related to theme concerned, besides the level of ambient consciousness given to the students are median. It was observed that teachers have little knowledge about theme like Agenda 21 and ISO14000. After identifying some factors of environmental knowledge, it was showed recommendations. The Agenda 21 recognizes in the educational field a mean of popular consciousness; the school should develop an education according to national policy of the environmental education

Saguis (Callithrix jacchus) sob ciclo claro-escuro de 21 h: um modelo de dessincronização forçada em primata diurno

The circadian system consists of multiple oscillators organized hierarchically, with the suprachiasmatic nucleus (SCN) as the master oscillator to mammalians. There are lots of evidences that each SCN cell is an oscillator and that entrainment depends upon coupling degree between them. Knowledge of the mechanism of coupling between the SCN cells is essential for understanding entrainment and expression of circadian rhythms, and thus promote the development of new treatments for circadian rhythmicity disorders, which may cause various diseases. Some authors suggest that the dissociation model of circadian rhythm activity of rats under T22, period near the limit of synchronization, is a good model to induce internal desynchronization, and in this way, enhance knowledge about the coupling mechanism. So, in order to evaluate the pattern of the motor activity circadian rhythm of marmosets, Callithrix jacchus, in light-dark cycles at the lower limit of entrainment, two experiments were conducted: 1) 6 adult females were submitted to the LD symmetric cycles T21, T22 and T21.5 for 60, 35 and 48 days, respectively; 2) 4 male and 4 female adults were subjected to T21 for 24 days followed by 18 days of LL, and then back to T21 for 24 days followed by 14 days of LL. Vocalizations of all animals and motor activity of each one of them were continuously recorded throughout the experiments, but the vocalizations were recorded only in Experiment 1. Under the Ts shorter than 24 h, two simultaneous circadian components appeared in motor activity, one with the same period of LD cycle, named light-entrained component, and the other in free-running, named non-light-entrained component. Both components were displayed for all the animals in T21, five animals (83.3%) in T21.5 and two animals (33.3%) in T22. For vocalizations both components were observed under the three Ts. Due to the different characteristics of these components we suggest that dissociation is result of partial synchronization to the LD cycle, wherein at least one group oscillator is synchronized to the LD by relative coordination and masking processes, while at least another group of oscillators is in free-running, but also under the influence of masking by the LD. As the T21 h was the only cycle able to promote the emergence of both circadian components in circadian rhythms of all Callithrix jacchus, this was then considered the lower entrainment limit of LD cycle promoter of dissociation in circadian rhythmicity of this species, and then suggested as a non-human primate model for forced desynchronization

HIGH STRENGTH CONCRETE: THE REINFORCED CONCRETE OF THE CENTURY 21(ST)

This work is about the 21st century reinforced concrete analysis under the point of view of its constituent materials. First of all it is described the theoretical approach of the bending elements calculated based on the Norms BAEL 91 standarts. After that, numerical load-displacement are presented from reinforced concrete beams and plates validated by experimental data. The numerical modellings has been carried on in the program CASTEM 2000. In this program a elastoplastic model of Drucker-Prager defines the rupture surface of the concrete in non associative plasticity. The crack is smeared on the Gauss points of the finite elements with formation criterion starting from the definition of the rupture surface in the branch traction-traction of the Rankine model. The reinforcements were modeled in a discrete approach with perfect bond. Finally, a comparative analysis is made between the numerical results and calculated criteria showing the future of high performance reinforced concrete in this beginning of 21st century.

Effect of soccer training on the running speed and the blood lactate concentration at the lactate minimum test

Tegtbur et al. [23] devised a new method able to estimate the intensity at maximal lactate steady state termed lactate minimum test. According to Billat et al. [7], no studies have yet been published on the affect of training on highest blood lactate concentration that can be maintained over time without continual blood lactate accumulation. Therefore, the aim of the present study was to verify the effect of soccer training on the running speed and the blood lactate concentration (BLC) at the lactate minimum test (Lac(min)). Thirteen Brazilian male professional soccer players, all members of the same team playing at National level, volunteered for this study. Measurements were carried out before (pre) and after (post) eight weeks of soccer training. The Lac(min) test was adapted to the procedures reported by Tegtbur et al. [23]. The running speed at the Lac(min) test was taken when the gradient of the line was zero. Differences in running speed and blood lactate concentration at the Lac(min) test before (pre) and after (post) the training program were evaluated by Student's paired t-test. The training program increased the running speed at the Lac(min) test (14.94 +/- 0.21 vs. 15.44 +/- 0.42* km(.)h(-1)) and the blood lactate concentration (5.11 +/- 2.31 vs. 6.93 +/- 1.33* mmol(.)L(-1)). The enhance in the blood lactate concentration may be explained by an increase in the lactate/H+ transport capacity of human skeletal muscle verified by other authors.

Energy-dependent point interaction: Self-adjointness

Recently, we constructed an energy-dependent point interaction (EDPI) in its most general form in one-dimensional quantum mechanics. In this paper, we show that stationary solutions of the Schrodinger equation with the EDPI form a complete set. Then any nonstationary solution of the time-dependent Schrodinger equation can be expressed as a linear combination of stationary solutions. This, however, does not necessarily mean that the EDPI is self-adjoint and the time-development of the nonstationary state is unitary. The EDPI is self-adjoint provided that the stationary solutions are all orthogonal to one another. We illustrate situations in which this orthogonality condition is not satisfied.
