Analysis of fluctuation conductivity of polycrystalline Er1-xPr xBa2Cu3O7-δ...
Jurelo,A.R.; Menegotto Costa,R.; Andrade,A.V.C. de; Júnior,P.R.; Cruz,G.K. da; Lopes,C.S.; Santos,M. dos; Sousa,W.T.B. deIn this work we report on conductivity fluctuation measurements in polycrystalline samples of the Er1-xPr xBa2Cu3O7-δ superconductor (x = 0.00, 0.05 and 0.10). Samples were prepared by a standard solid-state reaction technique. The results were analyzed in terms of the temperature derivative of the resistivity and of the logarithmic temperature derivative of the conductivity that allowed the identification...

Alterações anátomo-histopatológicas em ratos submetidos à dieta com extrato de ...
Cruz,G.D.; Bracarense,A.P.F.R.L.; Yamasaki,L.; Cortez,D.E.A.The carcinogenicity of bracken fern harvest from two regions of Paraná State to induce hematury in rats was studied. In order to do that, 33 Wistar rats were divided in three groups. Groups I and II received an aqueous extract of bracken fern from Londrina-PR or Ibaiti-PR, respectively, in drinking water for 60 days. Group III, control group, received regular plain water with no bracken fern. After 15 months, e...

Ir-Ru/Al2O3 catalysts used in satellite propulsion
Soares Neto,T.G.; Gobbo-Ferreira,J.; Cobo,A.J.G.; Cruz,G.M.Ir/Al2O3, Ir-Ru/Al2O3 and Ru/Al2O3, catalysts with total metal contents of 30% were prepared using the methods of incipient wetness and incipient coimpregnation wetness and were tested in a 2N microthruster. Their performances were then compared with that of the Shell 405 commercial catalyst (30% Ir/Al2O3). Tests were performed in continuous and pulsed regimes, where there are steep temperature and pressure gra...
A variedade IAC86-2480 como nova opção de cana-de-acuçar para fins forrageiros:...
LANDELL, M. G. A. de; CAMPANA, M. P.; RODRIGUES, A. A. de; CRUZ, G. M. da; BATISTA, L. A. R.; FIGUEIREDO, P.; SILVA, M. A. de; BIDOIA, M. A. P.A cana-de-açúcar tem se tornado um alimento volumoso de uso preferencial entre os pecuaristas por apresentar características, tais como: facilidade de cultivo, execução da colheita justamente na época de estiagem, possibilidade de auto-armazenamento ou conservação a campo, persistência da cultura e grande produção obtida em condições do Centro-Sul do Brasil. ; 2002
Transmissão congênita de Babesia bovis
Bracarense,A.P.F.L.; Vidotto,O.; Cruz,G.D.A case of prenatal Babesia bovis infection in Brazil in a 17 year-old Holstein × Brown Swiss cow which aborted at approximately eight months of gestation is described and discussed. The newborn calf outlived for few minutes and then died. At necropsy, the thoracic and abdominal cavities were filled by a great volume of a transparent liquid and petechial hemorrhages in oral mucosa and epicardium were observed. H...
Effects of terpineol on the compound action potential of the rat sciatic nerve
Moreira,M.R.; Cruz,G.M.P.; Lopes,M.S.; Albuquerque,A.A.C.; Leal-Cardoso,J.H.Terpineol, a volatile terpenoid alcohol of low toxicity, is widely used in the perfumery industry. It is an important chemical constituent of the essential oil of many plants with widespread applications in folk medicine and in aromatherapy. The effects of terpineol on the compound action potential (CAP) of rat sciatic nerve were studied. Terpineol induced a dose-dependent blockade of the CAP. At 100 µM, terpin...
DECOMPOSITION OF HYDRAZINE BY TUNGSTEN OXYCARBIDES: THE INFLUENCE OF MACROPOROS...
Vieira,R.; Cruz,G.M.; Rodrigues,J.A.J.The aim of this work was to prepare tungsten oxycarbides by Temperature Programmed Reaction (TPR), starting with previously molded macroporous tungsten oxide (WO3). The tungsten oxycarbides were prepared by one of two different methods: direct carburization with CH4/H2 to obtain WC or preliminary formation of nitrides with NH3 to obtain W2N, followed by carburization to W2C and WC with CH4/H2. Results suggested...
