1. Comportamiento a la Corrosión del Acero API X70 Soldado por el Proceso de Doble Arco Sumergido Inmerso en Diferentes Medios Corrosivos
Abstract The steels API X70 are applied in construction and fabrication of pipeline for transport of hydrocarbons, however, to lapse time are degrade due to environment to which are exposed, influencing on mode and corrosion rate on surface base metal (BM), heat zone affected (HAZ) and fusion zone (FZ). In order to know and evaluate the corrosion susceptibi

2. Transport Properties of Binary Solutions Containing the Ionic Liquid BMI.BF4 and Ethylene Glycol
The ionic conductivity values of the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate (BMI.BF4) and ethylene glycol (EG) electrolytes in different concentrations and over a wide temperature range were determined. The results are discussed in terms of the interactions between the cations and anions of the ionic liquid and the organic solvent. T

3. Roles of estrogen and progesterone in modulating renal nerve function in the rat kidney
The maintenance of extracellular Na+ and Cl- concentrations in mammals depends, at least in part, on renal function. It has been shown that neural and endocrine mechanisms regulate extracellular fluid volume and transport of electrolytes along nephrons. Studies of sex hormones and renal nerves suggested that sex hormones modulate renal function, although thi

4. Efeito de inibidores da ciclooxigenase sobre o transporte ileal de Ãgua e eletrÃlitos em ratos anestesiados
Esse estudo tem por finalidade avaliar os efeitos de inibidores seletivos da COX (cetorolaco e celecoxibe) e de inibidores nÃo seletivos (indometacina) da COX sobre o transporte ileal de Ãgua e eletrÃlitos em ratos anestesiados. TambÃm se propÃe a avaliar as alteraÃÃes vilo/cripta do Ãleo de ratos tratados com inibidores seletivos e nÃo seletivos da

5. Efeitos da hipervolemia crÃnica sobre a motilidade gastrintestinal e transporte intestinal de Ãgua e eletrÃlitos em ratos sob nefrectomia parcial / Effects of chronic hypervolemia on gastrointestinal motility and intestinal transport of water and electrolytes in rats under partial nephrectomy
Està bem estabelecido que a regulaÃÃo dos lÃquidos corporais seja garantida pela interaÃÃo funcional entre os sistemas cardiovascular e renal. Atualmente, evidÃncias clÃnicas e experimentais sugerem que o trato gastrintestinal (TGI) ajusta seu padrÃo motor e absortivo apÃs variaÃÃes agudas da volemia. Embora a insuficiÃncia renal parcial ou tota

6. Properties and applications of perovskite proton conductors
A brief overview is given of the main types and principles of solid-state proton conductors with perovskite structure. Their properties are summarized in terms of the defect chemistry, proton transport and chemical stability. A good understanding of these subjects allows the manufacturing of compounds with the desired electrical properties, for application i

7. Effect of age and gender on sweat lactate and ammonia concentrations during exercise in the heat
The dependence of sweat composition and acidity on sweating rate (SR) suggests that the lower SR in children compared to adults may be accompanied by a higher level of sweat lactate (Lac-) and ammonia (NH3) and a lower sweat pH. Four groups (15 girls, 18 boys, 8 women, 8 men) cycled in the heat (42ºC, 20% relative humidity) at 50% VO2max for two 20-min bout

8. Síntese e caracterização de NiO-CGO para anodo e eletrólitos sólidos e base de Céria para SOFC
The direct use of natural gas makes the Solid Oxide Fuel Cell (SOFC) potentially more competitive with the current energy conversions technologies. The Intermediate Temperature SOFC (IT-SOFC) offer several advantages over the High Temperature SOFC (HT-SOFC), which includes better thermal compatibility among components, fast start with lower energy consumptio

9. A renal study of the interactions between uroguanilia, urodilatia and predry bradiciiana of the chokes of the guanilato ciclase isatin and ODQ / Um estudo renal das interaÃÃes entre uroguanilia, urodilatina e bradicinina na presenÃa dos bloqueadores da guanilato ciclase isatin e ODQ
IntroduÃÃo: Guanilinas, peptÃdeos natriurÃticos (ANP e urodilatina) e bradicinina estÃo implicados na fisiopatologia, com potencial terapÃutico, do metabolismo do sal e da hipertensÃo. Objetivo: Estudar o mecanismo de aÃÃo e possÃveis interaÃÃes destes peptÃdeos, pelo emprego de inibidores da guanilato ciclase isatina e ODQ. MÃtodo: Foram reali

10. Efeitos da inibição da protoporfirinogênio IX oxidase sobre as trocas gasosas e fluorescência da clorofila a em plantas de soja (Glycine max L. Merrill) / Effects of inhibition of protoporphyrinogen oxidase IX on gas exchange and chlorophyll fluorescence of soybean plants (Glycine max L. Merrill)
The photosynthetic fixation of CO2 depends on the capture of light energy by the harvest complex (chlorophyll b and carotenoids), which transfer the energy to the photosystems reaction centers (chlorophyll a). The electrons transfer chain established between the photosystems generates reducing power necessary for the CO2 fixation in the Calvin cycle. The int

11. ESTUDOS GENÉTICOS SOBRE A VIRULÊNCIA DE Escherichia coli ENTEROAGREGATIVA ATÍPICA / Genetic studies on the virulence of atypical enteroaggregative Escherichia coli.
Escherichia coli enteroaggregative (EAEC) is emerging as a significant diarrheal pathogen. EAEC is defined by its characteristic stacked brick aggregative adherence (AA) pattern of adherence to HEp-2 cells. Most EAEC strains harbor a 60 to 65-MDa virulence plasmid (pAA). A 1-Kb fragment of pAA, referred to as the AA probe or CVD432, has been widely used for

12. Estudo dos efeitos renais do veneno da serpente Crotalus durissus collilineatus / Study about renal effects of Crotalus durissus collilineatussnake venom
Crotalus durissus collilineatus is a snake usually found in semideciduous forest, the Cerrado region and its bites constitutes an important health problem. The most serious systemic change and primary cause of death is acute renal failure although the mecanisms of the damaging effects are not totally understood. We investigated the biological effects promote
