1. Study of nanocomposites with carbon nanotubes and their tendency for carbon organization
Abstract The carbon derived from the thermal treatment of modified phenolic resins (PR) tends to organize into graphitic lamellae or turbostratic carbon and is commonly considered non-graphitizable. In this study, nanocomposites were synthesized with modified phenolic resin (Novolac) used as the matrix and oxidized multi-walled carbon nanotubes (NTox) in amo

2. Characterization and mechanical properties of one-part geopolymer based on a pure metakaolin
Abstract Geopolymers are amorphous silicate polymers that have been extensively studied due to their applications, scientific and technical relevance, and their potential as cement in substitution to Portland. Much of the focus has been in the use of precursors and aggregates that are rarely pure and homogeneous with the use of tailings being very common. Th

3. Maternal Intake of Flaxseed During Lactation and Exercise Training Protect Against Salt Overload-Induced Aortic Remodeling in Adult Offspring
Abstract Background High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure. Objectives To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation. Methods Female rats were fed with a control

5. Number of laminae on the mechanical behavior of glued laminated timber (glulam) of Toona ciliata produced with vegetable polyurethane adhesive
RESUMO A madeira laminada colada (MLC) é um material compósito obtido a partir da colagem de lâminas de madeira dispostas com as fibras paralelas entre si. O objetivo deste trabalho foi avaliar a influência do número de lâminas no comportamento mecânico de MLC de Toona ciliata produzidas com adesivo poliuretano de base vegetal. As vigas de MLC foram p

6. The larva of Neoneura confundens Wasscher and van’t Bosch, 2013 (Odonata, Coenagrionidae) and key to the larvae of genus
Abstract: The beautifully colored damselflies included in Neoneura Selys are divided in 28 species known from North, Central and South America. Larval stage is little known, only seven species were described at this stage. We describe and illustrate the final instar larva of Neoneura confundens for the first time. Adults associated to this larva correspond t

7. Peppermint essential oil as an anesthetic for and toxicity to juvenile silver catfish
Resumo: O objetivo deste trabalho foi avaliar a toxicidade e o potencial como anestésico do óleo essencial de hortelã-pimenta (Mentha piperita) para juvenis de jundiá (Rhamdia quelen). Para determinar a concentração letal em 4 horas (CL50-4h), 210 peixes (3,08±0,8 g e 7,59±0,67 cm) foram expostos a 0, 20, 50, 80, 110 e 140 mg L-1 do óleo essencial.

8. CHEMICALLY TREATED GLUED LAMINATED PARICÁ TIMBER (Schizolobium parahyba var. amazonicum)
ABSTRACT In the production of glue-laminated timber (GLT), boards derived from planted forest wood with easy workability are glued on top of one another. The main objective of the present work was to evaluate the performance of paricá timber GLT beams (5 × 10 cm) on GLT. Three procedures were performed: (1) GLT beams (5 × 10 cm) were produced using natura

9. A second record of Entoloma azureoviride (Agaricales, Basidiomycota) from Brazilian Amazon
RESUMO Um novo material coletado e o holótipo de Entoloma azureoviride foram estudados. A análise desses espécimes revelou algumas discrepâncias em relação ao protólogo que discutidassão discutidas no presente trabalho. As características diagnósticas da espécie são: píleo fibriloso, lamelas azuis, esporos cuboides e abundância de hifas oleífe

10. Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry & Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or

11. Microstructural Evolution of a Pearlitic Steel Subjected to Thermomechanical Processing
The microstructural alterations suffered during the process of drawing deformation and subsequent annealing of pearlitic steel wires, were evaluated by scanning electron microscopy and atomic force microscopy. The deformed material showed the curling structure in cross section while, in the longitudinal section, the lamellae was aligned with the drawing dire
