This word has objective to analyzer the relevance of the use of the cartographic representations, in the constructions of the geographical knowledge, during the process of the teaching-learning in the classes of the Geographic of the High School, drawing liam with the formation docent of the regulars courses of teacher training in the regular courses of Degree in Geography. Delimit is the area of empiric search to College State Zacarias de Goes (CEZG) Liceu Piauiense, and to regulars courses of Degree in Geography of the University Federal of the Piauí (UFPI) and University State of the Piauí (UESPI), educational institutions of the public network, located in the city of the Teresina Piauí. Expression of the problematic searched is gaps to been demystified on the vision cartofógica, when has reference to use of the cartographic representations, in the practice, and the initial formation docent in the Geography. To analyze the dynamics of the use of the cartographic resources, tried demystify the Cartography while of the space during the teaching of discipline Geography. So, the lyam with the initial formation in the begree search understand the impasses of construction to academic know and the possibilities of the didactic transposition to the restructure of the know scholar to teacher who works in the Geography, trying to make the teaching of this discipline more interesting and value

Este artigo apresenta as conseqüências do Programa Dinheiro Direto na Escola para a esfera da gestão das escolas públicas, especialmente aquelas relativas às conexões entre a constituição e gestão da esfera pública e da esfera privada. de certa forma, acreditamos que o PDDE materializa mudanças ocorridas no papel do Estado. Os resultados encontrados, com destaque para aqueles que envolveram a indução à criação de unidades de direito privado para o recebimento e gestão dos recursos descentralizados, organizam-se a efeito deste artigo, tendo em vista três aspectos constitutivos da gestão educacional: a democratização da gestão da escola, a relação público e privado e a relação entre descentralização e centralização.

O comportamento da veia ázigos, sua formação e topografia foram estudados em 10 cutias (Dasyprocta aguti, rodentia) adultas (6 machos e 4 fêmeas, capturadas no estado do Piauí, Brasil). Este trabalho tem por objetivo constituir a base de outras investigações, particularmente aquelas referentes à exploração zootécnica desta espécie. O sistema de veia ázigos foi injetado com látex - Neoprene 671, e os animais foram colocados em solução aquosa de formol a 10%, e dissecados. em todas as espécies foi observado que a veia ázigos sempre chega na veia cava cranial em nível do quarto espaço intercostal. A veia ázigos recebe em (50%) dos casos as veias intercostais à direita e (50%) à esquerda. As tributárias da veia ázigos são: as veias frênicas (100%) e a veia bronco esofágica (30%). A veia hemiázigos aparece em todos os casos à esquerda e em 60% dos casos à direita. A veia ázigos comunica-se com a veia hemiázigos esquerda (90%), e com a direita (100%), com a veia cava caudal e veias intervertebrais, com igual freqüência (30%).

This study aimed to quantify the effects of agroforestry systems (AFS), with different periods of adoption, and slash and burn agriculture (SB) on the chemical attributes of an Ultisol in the 'Cerrado' of Piaui State, Brazil. In two distinct climatic seasons (dry and rainy) four systems were studied: AFS with six (AFS6) and thirteen years (AFS13) of adoption, an area under SB and a native forest (NF), as a reference. In the AFS, in all depths, higher reduction in the Al3+ and H+ + Al3+ contents were observed as well as an increase of pH value and contents of nutrients (N, P, Ca, Mg and K) and organic carbon in soil. In the soil under SB, only in superficial layers, the ash deposited on the soil caused an increase in contents of nutrients, except for P, which was higher in all the depths. There was significant seasonal effect in the contents of nutrients, reducing in the rainy season. Agroforestry systems promoted increase in the nutrient contents of an Ultisol and can be considered useful to improve soil chemical quality in areas of 'Cerrado' of Piau State, Brazil.

This work aimed to evaluate the effects of liming and phosphate fertilizer for the production of sabiá (Mimosa caesalpiniifolia Benth.) seedlings without thorns under a greenhouse. Seedlings 10 days old were transferred to plastic bags containing 2.0 kg of psamitic Dystrophic Red-Yellow Latosol (Typic Haplustox) collected from 40 to 70 cm layer. The experiment was carried out in Teresina county, Piauí state, Brazil, from July to October of 2008. Two liming doses (with and without liming) and five phosphorus doses combined in a 2 x 5 factorial scheme were used. The experimental design used was the randomized blocks with four replications having each plot three seedlings. The calculated lime amount was enough to elevate the base saturation to 50 % and the phosphorus doses were: 0, 30, 60, 90, and 120 mg kg-1 of soil. One seedling per pot was cultivated and the pot dimension was 10 by 23 cm. The evaluated variables were height, diameter, leaves number, leaf area, and shoot and roots dry matter. For the studied soil condition, the liming is not necessary to produce 'Sabiá' seedlings. The application, on average, from 72 to 107 mg kg-1 of P promote, respectively, from 90 to100 % of maximum values of height, diameter, leaf area and shoots and roots biomass.

Background: Intensive fish farming results in stress adversely effecting the performance of farmed fish. Plasma cortisol is a validated measure of stress in fish. We evaluated the effect of a homeopathic complex on the cortisol level of Nile tilapias (Oreochromis niloticus). Method: 60 animals with approximate average weight of 100 g each at the start of experiment were randomly distributed in six glass fiber water tanks, capacity 1000 liters, with a daily water renewal rate of 20%. They received one of two treatments: 30 animals in control treatment and 30 animals receiving the homeopathic complex Homeopatila 100. On days 1, 30 and 60, all fish were anesthetized and blood was collected by puncture on the caudal vein, to determine the levels of circulating cortisol. Results: At the end of the experiment the fish receiving a homeopathic complex, had significantly lower circulating cortisol level (17.96 ng/mL ± 0.95) than the control group (38.68 ng/mL ± 1.21) (p < 0.05). Conclusions: Cortisol levels were significantly lower in the treated group than control, and the fish were larger in the treated group. © 2013 The Faculty of Homeopathy.
