13. Energy generation in a Microbial Fuel Cell using anaerobic sludge from a wastewater treatment plant
ABSTRACT In microbial fuel cells (MFCs), the oxidation of organic compounds catalyzed by microorganisms (anode) generates electricity via electron transfer to an external circuit that acts as an electron acceptor (cathode). Microbial fuel cells differ in terms of the microorganisms employed and the nature of the oxidized organic compound. In this study, a co

14. A protocol for measuring spatial variables in soft-sediment tide pools
ABSTRACT We present a protocol for measuring spatial variables in large (>50 m2) soft-sediment tide pool. Secondarily, we present the fish capture efficiency of a sampling protocol that based on such spatial variables to calculate relative abundances. The area of the pool is estimated by summing areas of basic geometric forms; the depth, by taken representat

15. β-Citronellol, an alcoholic monoterpene with inhibitory properties on the contractility of rat trachea
β-Citronellol is an alcoholic monoterpene found in essential oils such Cymbopogon citratus (a plant with antihypertensive properties). β-Citronellol can act against pathogenic microorganisms that affect airways and, in virtue of the popular use of β-citronellol-enriched essential oils in aromatherapy, we assessed its pharmacologic effects on the contracti

16. Application of Bar Adsorptive Microextraction-Large-Volume Injection-Gas Chromatography-Mass Spectrometric Method for the Determination of Trace Levels of Agrochemicals in Real Matrices
Bar adsorptive microextraction followed by liquid desorption in combination with large volume injection gas chromatography coupled to mass spectrometry, under selected ion monitoring mode acquisition (BAµE-LD/LVI-GC-MS(SIM)), was applied for the determination of trace levels of different classes of agrochemicals (using alachlor, diniconazole, fenpropathrin,

17. Habituation of enterotoxigenic
Staphylococcus aureus toOriganum vulgare L. essential oil does not induce direct-tolerance and cross-tolerance to salts and organic acidsEnterotoxigenic
Staphylococcus aureus strains that were isolated from foods were investigated for their ability to develop direct-tolerance and cross-tolerance to sodium chloride (NaCl), potassium chloride (KCl), lactic acid (LA) and acetic acid (AA) after habituation in sublethal amounts (1/2 of the minimum inhibitory concentration - 1/2Braz.

18. High-fidelity simulation versus case-based discussion for teaching medical students in Brazil about pediatric emergencies
OBJECTIVE: To compare high-fidelity simulation with case-based discussion for teaching medical students about pediatric emergencies, as assessed by a knowledge post-test, a knowledge retention test and a survey of satisfaction with the method. METHODS: This was a non-randomized controlled study using a crossover design for the methods, as well as multiple-

19. Antibiotic resistance and integrons in Shiga toxin-producing Escherichia coli (STEC)
Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolytic-uremic syndrome in humans (HUS). Cattle are the main reservoir of STEC and transmission to humans occurs through contaminated food and water. Antibiotics are used in pig production systems to combat disease and improve productivity and play a key role in the disseminat

20. Possible roles of COX-1 in learning and memory impairment induced by traumatic brain injury in mice
People who suffer from traumatic brain injury (TBI) often experience cognitive deficits in spatial reference and working memory. The possible roles of cyclooxygenase-1 (COX-1) in learning and memory impairment in mice with TBI are far from well known. Adult mice subjected to TBI were treated with the COX-1 selective inhibitor SC560. Performance in the open f

21. Efecto del feedback correctivo directo y metalingüistico en el proceso de escritura de una L2 en el contexto escolar: estudio piloto
Since the early research in Second Language Acquisition (SLA), studies of Written Corrective Feedback (WCF) sought to answer several questions about CF and especially WCF: reasons to correct errors, which errors to correct, when to correct, how to correct and by whom. However, initial studies did not focus on the question that is vital in this area today, th

22. Application of computational chemistry methods to obtain thermodynamic data for hydrogen production from liquefied petroleum gas
The objective of this study was to estimate thermodynamic data, such as standard enthalpy, entropy and Gibbs free energy changes of reaction and, consequently, chemical equilibrium constants, for a reaction system describing the hydrogen production from Liquefied Petroleum Gas (LPG). The acquisition of those properties was made using computational chemistry

23. Sertraline inhibits formalin-induced nociception and cardiovascular responses
The objective of the present study was to determine the antihyperalgesic effect of sertraline, measured indirectly by the changes of sciatic afferent nerve activity, and its effects on cardiorespiratory parameters, using the model of formalin-induced inflammatory nociception in anesthetized rats. Serum serotonin (5-HT) levels were measured in order to test t

24. Universidade Aberta à Terceira Idade: efeitos sobre a qualidade de vida percebida / University of the Third Age: effects on perceived quality of life
The education in the old age is intended to promote the acquisition of knowledge that determines the resizing for the fomentation of the quality of life (QoL) from the assumptions of interdisciplinarity, social participation and health promotion. With the objective of evaluating the effects of the University of the Third Age (UTA) from the Fundação Educaci
