1. COMO A IDADE DO PERFILHO E A ADUBAÇÃO NITROGENADA MODIFICAM AS CARACTERÍSTICAS ESTRUTURAIS DO CAPIM-MARANDU DIFERIDO?
Resumo Este estudo avaliou as características estruturais de perfilhos, com diferentes idades, do capim-marandu (Urochloa brizantha cv. Marandu) diferido e adubado. Foram avaliadas duas doses de nitrogênio (baixa, 50 kg ha-1 e alta, 200 kg ha-1), três categorias de idades de perfilhos (jovem, <2 meses; maduro, 2 a 4 meses; e velho, > 4 meses;), além de d

2. Mecanismos de queda do fluxo em membranas de microfiltração de poliéterimida aplicadas à clarificação de água produzida sintética
RESUMO Membranas de microfiltração de poliéterimida foram preparadas pelo método de inversão de fases para controlar a espessura, porosidade e tamanho de poros dos filmes. 1-metil-2-pirrolidona foi utilizada como solvente e água como não solvente. As propriedades das membranas foram avaliadas por meio de microscopia eletrônica de varredura, microfilt

3. Productive Performance, Egg Characteristics and Hatching Traits of Three Chicken Genotypes under Free-Range, Semi-Intensive, and Intensive Housing Systems
ABSTRACT The present study aimed at evaluating the effect of housing system on the live performance, egg quality, and hatching traits of three dual-purpose chicken genotypes. In total, 180 birds, comprising 48 pullets and 12 cockerels from each of three genotypes, were evaluated during the production phase (27-46 weeks). For this, 144 pullets and 36 cockerel

4. Apparent selectivity of sheep in deferred marandu palisadegrass pastures with variable initial heights
RESUMO Objetivou-se avaliar a seletividade aparente de ovinos em pastos de capim-marandu (Urochloa brizantha cv. Marandu) com quatro alturas no início do diferimento (15, 25, 35 e 45cm). O período de diferimento foi de 92 dias e iniciou em 21/03/2014. As avaliações ocorreram no início (primeira semana), meio (45° dia) e fim (92° dia) do período de pa

6. Application of a composite ultrafiltration membrane for biodiesel purification
ABSTRACT This study was carried out to investigate the potentialities of the application of membrane technology in biodiesel purification without need of the decantation step. A new composite UF membrane was prepared from poly(vinylidene fluoride) casting solution (17 wt%) containing a sulfonated Carbon (20 wt%). The assays were performed in a dead-end filtr

8. Protective effects of silymarin on methotrexate-induced damages in rat testes
Abstract The present study aimed to investigate the protective effects of silymarin (SMN), an antioxidant, on methotrexate (MTX)-induced damage in rat testes. Thirty-two Wistar albino rats were divided into four groups (n = 8): control, MTX (20 mg/kg, i.p. on days 1 and 5), SMN (200 mg/kg, orally), and MTX + SMN (20 mg/kg, i.p. on days 1 and 5 and SMN 200 mg

10. Stranded humpback whale (Megaptera novaeangliae) (Cetacea: Balaenopteridae) in Paraná River Delta, Buenos Aires Province, Argentina. Comments on the occurrence of marine mammals in the La Plata River Basin
Abstract The humpback whale (Megaptera novaeangliae) is distributed among most oceans and seas of the globe (except Mediterranean Sea). These whales migrate from feeding regions in the Antarctic waters to breeding areas in tropical and subtropical seas. Here we report the stranding of a female young humpback whale, which was founded dead in the vicinity of t

11. Respiratory evaluation through volumetric capnography among grade III obese and eutrophic individuals: a comparative study
ABSTRACT BACKGROUND: Excess trunk body fat in obese individuals influences respiratory physiological function. The aims of this study were to compare volumetric capnography findings (VCap) between severely obese patients and normal-weight subjects and to assess whether there is any association between neck circumference (NC), waist-hip ratio (WHR) and VCap

12. Phenomenal Conservatism and the Demand for Metajustification
ABSTRACT This paper is on the justification of (PC), the epistemic principle defended by M. Huemer in his Phenomenal Conservatism theory. Put in a straightforward way, we can (and should) ask: what reasons are there for thinking that (PC) is true, that is, for thinking that appearances justify beliefs? This question corresponds - to use L. BonJour’s vocabu
