Optical coherence tomography evaluation of retinal nerve fiber layer in longitu...
Moura,Frederico C.; Fernandes,Danilo B.; Apóstolos-Pereira,Samira L.; Callegaro,Dagoberto; Marchiori,Paulo E.; Monteiro,Mário L.R.OBJECTIVE: To compare optical coherence tomography (OCT) measurements on the retinal nerve fiber layer (RNFL) of healthy controls and patients with longitudinally extensive transverse myelitis (LETM) without previous optic neuritis. METHOD: Twenty-six eyes from 26 patients with LETM and 26 control eyes were subjected to automated perimetry and OCT for comparison of RNFL measurements. RESULTS: The mean deviation...
Nitrous oxide and methane fluxes in south Brazilian gleysol as affected by nitr...
Zanatta,Josiléia Acordi; Bayer,Cimélio; Vieira,Frederico C.B.; Gomes,Juliana; Tomazi,MichelyNitrogen fertilizers increase the nitrous oxide (N2O) emission and can reduce the methane (CH4) oxidation from agricultural soils. However, the magnitude of this effect is unknown in Southern Brazilian edaphoclimatic conditions, as well as the potential of different sources of mineral N fertilizers in such an effect. The aim of this study was to investigate the effects of different mineral N sources (urea, ammo...
Analysis of an alternative method for the study of bromeliad-associated fauna i...
Müller,Gerson A.; Name,Fernando T.; Pacheco,Frederico C.L.; Marcondes,Carlos B.The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at Florianópolis, SC, Brazil, was studied. The alternative method was less efficient to collect Culicidae and Chironomidae (Wilcoxon test p < 0.05) and was more efficie...
Caracterização química de azeites elementares da região de Trás-os-Montes.
Sousa, A.; Casal, Susana; Frederico, C.; Cosme, V.; Bento, Albino; Oliveira, M.B.P.P.; Pereira, J.A.Trás-os-Montes é uma das principais regiões produtoras de azeite a nível nacional, onde é produzido azeite com a Denominação de Origem Protegida “Azeite de Trás-os-Montes”. De uma forma geral, estes azeites resultam de uma mistura de diferentes cultivares, maioritariamente Cobrançosa, Madural e Verdeal Transmontana, sendo permitida a presença de outras, ainda que em menor proporção. Com o presente trabalho pret...

Um espectômetro de massas de tempo-de-vôo para o estudo da ionização de amostra...
Cardoso,Aldo S.; Pontes,Frederico C.; Souza,Gerardo Gerson B. de; Mundim,Maria Suely PedrosaA simple and inexpensive time-of-flight mass spectrometer, dedicated to the study of gas-phase ionization processes induced by high energy electrons (0.5 - 3.0 keV), is described. The spectrometer design is based on the Wiley-McLaren principle, with a total length of about 18 cm. As a demonstration of the performance of the apparatus, mass spectra for Ar, CH4, CO2, and SF6, obtained at 1 keV electron energy, ar...
