1. Crescimento e teor de cromo em mamoneira cultivada em solo receptor de resíduos de curtume e carboníferos
RESUMO A produção de resíduos tem aumentado em proporção direta com a industrialização dos países. Sendo assim, a disposição adequada desses resíduos é uma questão largamente discutida entre os órgãos ambientais. Por isso, o objetivo deste trabalho foi estudar o efeito residual de adições sucessivas de resíduos de curtume e da mineração d

2. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

3. Resposta da soja a adubacao e disponibilidade de potassio em latossolo roxo alico.
A sucessao soja-trigo tem sido empregada nos Latossolos Roxos alicos do Parana desde a decada de 70. Em todos esses anos, quando houve restricao de credito agricola, a maioria dos agricultores dispensou o uso de adubo ou, quando utilizou, aplicou menos potassio que o retirado pelas sementes. Essa pratica conduz ao empobrecimento do solo e, como consequencia,

4. Resposta da soja a adubacao e disponibilidade de potassio em latossolo roxo distrofico.
Com o objetivo de estudar a melhor tecnica de adubacao corretiva cm K e o efeito residual dessa adubacao, foi realizado um experimento de longa duracao em um Latossolo Roxo distrofico, no municipio de Maua da Serra, PR. Nos primeiros cinco anos de conducao do experimento (1983 a 1987), foram aplicadas, anualmente, as doses de cloreto de potassio de zero, 40,

5. Avaliação da contaminação por microorganismos esporulados e indicadores em requeijão cremoso / Microbiological evaluation of indicators and sporeforms in requeijão cream cheese
The objective of this research was to carry out a microbiological survey of Brazilian cream cheese ?Requeijão? ( pH 5,8 ), production line and to evaluate its shelf life, in relation to contamination by sporeformers and pathogens such as L. monocytogenes, coagulase positive S. aureus and Coliforms ( 45°C) and to determinate the microorganism(s), surviving

6. POTENCIAL DO Lupinus albescens Hook. &Arn. PARA RECUPERAÇÃO DE SOLOS ARENIZADOS DO BIOMA PAMPA.
As the productive processes move forward on the sandy soils of the Southwest region of Rio Grande do Sul, the arenização has been assuming relevance as factor of soil and regional ecosystem degradation. Contention measures should be established to avoid the progress of the arenização focuses and to recover the areas already damaged. Among these strategie

7. Agronomic efficiency and residual effect of pand k rock biofertilizers with acidithiobacillus in two lecttuce consecutive crops in a brazilian soil from the Cariri cearense / Eficiência agronômica e poder residual de biofertilizantes de rochas com acidithiobacilus em cultivos consecutivos com alface em solo do Cariri cearense
Production of rock biofertilizers is a practical process with reduction of energy consumption and increasing nutrients availability in soils. A field experiment was carried out applying P and K biofertilizers from phosphate rock (Apatite-PR) and potash rock (biotite-KR) plus sulfur inoculated with Acidithiobacillus, on lettuce (cv. Crespa) in two consecutive

8. Synaptic potentials in rat locus coeruleus neurones.
1. Intracellular recordings were made from locus coeruleus neurones in a slice of tissue cut from the rat pons. A depolarizing postsynaptic potential (PSP) followed electrical stimulation of the slice surface; the latency was 1-3 ms and the duration was 50-200 ms. 2. The reversal potential of the PSP (estimated by extrapolation from potentials between -60 an

9. Activation of protein kinase C inhibits calcium-activated potassium channels in rat pituitary tumour cells.
1. The regulation of large-conductance, calcium- and voltage-dependent potassium (BK) channels by protein kinase C (PKC) was investigated in clonal rat anterior pituitary cells (GH4C1), which were voltage clamped at -40 mV in a physiological potassium gradient through amphotericin-perforated patches. 2. Maximal activation of PKC by 100 nM phorbol 12, 13-dibu

10. Activation of a novel organic solute transporter in mammalian red blood cells.
1. Suspending human red blood cells in isotonic sucrose (low ionic strength, LIS) medium induces a significant increase in membrane transport of glutamine, glutamate, lactate, histidine, taurine, glycine, serine, choline and carnitine but not sorbitol or sucrose. 2. Progressive lowering of ionic strength by sucrose or NaCl replacement gave a similar activati

11. Inhibition of human red cell sodium and potassium transport by divalent cations.
The influx and efflux of Na and K across the human red cell membrane by the bumetanide-sensitive (Na-K co-transport) and residual (ouabain- and bumetanide-insensitive) routes were inhibited by increasing concentrations of external Mg. Ca, Sr, Ba, Mn and Co also inhibited bumetanide-sensitive and residual K transport. External Mg inhibited choline uptake and

12. Dependence on calcium of potassium- and agonist-induced changes in potassium permeability of rabbit ear artery.
The effect of K+ depolarization and agonists on the 86Rb+ efflux from rabbit ear artery has been investigated. K+ depolarization with 59 mM-K+ induces an increase of the 86Rb+ efflux rate, which is dependent on [Ca2+]o and is correlated with the concomitant force development. This effect is largely reduced by Ca2+ antagonists, such as D-600 and Mn2+. The res
