O artigo analisa as atuais políticas culturais e analisa empiricamente as ações da unidade paulistana do Centro Cultural Banco do Brasil (CCBB). O objetivo é interpretar como esta instituição opera o fomento à cultura no contexto da normatização cultural no Brasil. A articulação institucional entre Banco do Brasil e seu Centro Cultural enseja algumas particularidades no campo da difusão cultural, pois o status institucional do CCBB condiciona de maneira decisiva as formas como transcorrem as relações com produtores culturais, público consumidor e com seu respectivo mantenedor. Trata-se de estudo baseado em pesquisa bibliográfica, levantamento de campo e na abordagem dialética de análise. Conclui-se que, ao consentir um laissez-faire cultural, o Estado admite que o mercado imponha sua lógica à cultura, de modo que o objeto empírico pode ser caracterizado como um exemplo dessa dinâmica.

A total of 58 Ucides cordatus (Linnaeus, 1763) ovigerous females in final embryonic stage were collected in mangrove forest at Iguape (São Paulo). Each female were kept in laboratory until the larvae hatching and had their carapace width (CW) measured with caliper (0.05 mm) and the larval number (LN) calculated by volumetric method. The hatching rates (HR) were calculated for each animal's size class (5 mm). The values of LN and CW obtained were subjected to regression analyses and the best fitting model was chosen by comparing the obtained determination coefficients (R²). The fertility varied from 71,200 to 220,800 larvae (147,169 ± 32,070 larvae), corresponding to 41.7 to 76.8 mm CW (63.7±7.9 mm), respectively. The relationship LNxCW was expressed by the equation LN = 284.1CW1.5º¹ (N = 58; R² = 0.74; p < 0.01), that showed a positive correlation between the variables. Most part of ovigerous females (89.7%) showed their hatching during the nightly period. A negative correlation between HR and CW was observed in these animals (p < 0.05), probably due to reduction of spermatophores in the seminal receptacle (multiparous females) or due to senility in the females with large size. The biological studies of U. cordatus are very important for practices adoption that preserve and make the rational use of this recourse in Brazilian's mangrove forests.

The niche breadth of the Portunidae and their overlap on the subtidal sediments of Fortaleza bay, Ubatuba (São Paulo) was analyzed. Samples were made monthly from November/1988 to October/1989, inseven areas of the bay using a shrimp fishery boat equipped with two otter-trawls. Each area was characterized based on environmental factors such as depth, temperature, salinity, dissolved oxygen, organic matter and granulometric composition of the sediment. The number of individuais of each species was registered to each area (resource). Levins's standardized measure (BA) and niche percentage were calculated. Five species of swimming crabs were recorded in this study: Callinectes ornatus Ordway, 1863, Arenaeus cribrarius (Lamarck, 1818), Portunus spinimanus Latreille, 1819, Callinectes danae Smith, 1869 and Portunus spinicarpus (Stimpson, 1871). The widest ecological niche occurred to C. ornatus, present in all sampled areas (generalist species). Such fact can be related to high sediment tolerance when it is compared to P. spinimanus (especialist species) which was limited to the areas with coarse granulometric fractions. Highest niche overlap was verified between C. danae and A. cribrarius may be due to greater salinity tolerance of these species. The low occurrence of P. spinicarpus and its reduced niche size in Fortaleza Bay are due to association of this species to cold water currents (ACAS) more evidente in smaler depths during summer months. One future evaluation of the portunid diet can be useful to complement informations about this important aspect of the marine ecology.

Emerita brasiliensis Schmitt, 1935 is a common mole crab called tatuíra in Brazil, with distribution from Espírito-Santo State (Brazil) to Buenos Aires Province (Argentina). Specimens were collected bimonthly from May/1992 through March/1993 with 4mm siffers mesh, in the intertidal region at Vermelha do Norte Beach, Ubatuba, São Paulo, Brazil. The animals were sexed and measured with a precision caliper of 0.1 mm (Cl = carapace length). Males presented cl amplitude from 3.4-17.3mm (13.2±2.1mm), and females from 13.8-26.3mm (20.5±1.8mm), showing a well-defined sexual dimorfism for this variable. The population presented a smaller incidence of males in relation to females (0.54:1.00), however in May/1992 an inverse pattern occurred (1.84:1.00). Ovigerous females were present in all samples with exception of May and September/1992 with greater frequencies in July/1992 and January/1993. It is probable that female maturity occurs is reached with 17mm CL, the smallest size in wich ovigerous females were found.

For to establish the micronutrients sufficiency range for the cotton, was used the method of mathematical chance for nutritional monitory data of three cotton growth locations in the Midwest of the Brazil, evaluating 152 areas. The method of mathematical chance was adequate for to establish cotton micronutrients references values, can be to help parameters were the conventional research cannot to prove in the short time. The micronutrients sufficiency range for productivity of 4000kg ha(-1) were, in the mg kg(-1), 41-89; 4-14; 90-230; 23-100; 25-50, and for 4500kg ha(-1) was 53-83; 4-12; 110-440; 40-60 e 25-50 for B, Cu, Fe, Mn and Zn, respectively. The sufficiency ranges indicated was similar to the existing official recommendations, however, is indicated the approach for to supply the specifics of the systems. The limitations of the method can be minimized with the expansion of the nutritional monitoring system in the cotton crops.

The cotton growth occupies about 1.1 million hectares in Brazil and the midwest, especially the state of Mato Grosso, is the largest producer in the country. This work aimed to establish the sufficiency ranges for macronutrients in cotton crops by the method of mathematical chance. The work was carried out from 2000 to 2003 in the cities of Costa Rica (MS), Diamantino and Sapezal (MT), totaling 152 samples of plant tissue and yield. The chance mathematics method was adequate for to establish cotton macronutrients references values, can be to help parameters were the conventional research cannot to prove in the small time space. The use of different yields for the calculation of mathematical chance (4,000 and 4,500kg ha(-1)) in the population studied, no difference between the sufficiency ranges for macronutrients. The macronutrients sufficiency range was, in the mg kg(-1), 33-45; 3.8-5.3; 15-21; 20-36; 4.0-7.2 e 2.8-8.6 for N, P, K, Ca, Mg e S, respectly. The indicated range, however to similar with the recommendations published, they demonstrate improvement about to obtainment of increases productivities.

O objetivo deste trabalho foi analisar a variabilidade genética da raça Brahman no Brasil, por meio da análise de 15.851 pedigrees. O arquivo de dados foi dividido em dois períodos: 1998-2001 e 2002-2005. A variabilidade genética foi avaliada por parâmetros baseados na probabilidade de origem do gene: número efetivo de ancestrais, número efetivo de fundadores, número efetivo de genomas remanescentes e coeficientes de parentesco e de endogamia. Os valores encontrados quanto ao número de fundadores mostraram que a população está em expansão, embora o número efetivo de fundadores tenha diminuído de um período para outro. Os resultados foram diferentes em relação ao número de ancestrais e genomas remanescentes, que apresentaram crescimento de 23% nos períodos avaliados. O coeficiente de endogamia diminuiu nos períodos estudados, porém o coeficiente de parentesco inter se cresceu. Poucos ancestrais apresentaram grande contribuição genética para a população, o que evidencia a utilização de poucos indivíduos na reprodução. A raça Brahman, no Brasil, encontra-se em expansão, caracterizada pela diminuição do coeficiente de endogamia e aumento nos números efetivos de fundadores e de genótipos remanescentes. Entretanto, a variabilidade genética da raça mostra aumento do parentesco inter se e grande concentração do patrimônio genético de poucos indivíduos na população.

OBJETIVO: Avaliar a função renal de cães sadios, sob dois protocolos para administração de cisplatina. MÉTODOS: Todos os animais foram submetidos a três sessões de quimioterapia com cisplatina (60mg/m², iv) a intervalos de 21 dias. Foi realizada fluidoterapia com solução de cloreto de sódio a 0,9%, (25mL/kg/hora,iv), durante duas horas e, após administração de cisplatina, por mais uma hora. Os animais do grupo 2 receberam furosemida (2mg/kg, iv) 20 minutos antes da administração da cisplatina. A avaliação da função renal foi feita por exame clinico, urinálise, concentrações séricas de uréia e creatinina, clearance de creatinina, excreção fracionada de sódio e de potássio e razão proteína: creatinina urinária. As avaliações foram feitas imediatamente antes e 1, 2, 5, e 21 dias após cada uma das três sessões de quimioterapia. RESULTADOS: Mantiveram-se dentro da normalidade, não sendo detectados sinais de lesões ou insuficiência renal. Os animais que não receberam furosemida sofreram aumento gradativo nas concentrações séricas de creatinina e diminuição no clearance da mesma. CONCLUSÃO: O regime de fluidoterapia empregado mostra ser efetivo em minimizar a ação nefrotóxica da cisplatina e benefício adicional importante é obtido pela administração de furosemida.

The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment nº 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration
