14. Preservation of residual hearing after cochlear implant surgery: an exploration of residual hearing function in a group of recipients at cochlear implant units
Resumo Introdução: A preservação da audição residual tem se tornado cada vez mais importante na cirurgia de implante coclear. Conservar a audição residual é um indicador prognóstico positivo para melhorar as habilidades auditivas. Objetivo: Avaliar a preservação da audição residual pós-implante coclear em um grupo de pacientes de dois grande

15. Evaluation of the Plant Necromass Component: Methodological Approaches and Estimates in Atlantic Forest, Northeast Brazil
ABSTRACT Necromass is a crucial component for the forest structure. However, there are few studies of necromass quantification in tropical rainforests and lack of efficient sampling methods. This research aimed at verifying the accuracy and effectiveness of sampling methods (Line-intersect sampling - LIS versus fixed area plots - FA) for the estimation of ne

16. Incidence of Bemisia tabaci Gennadius (Aleyrodidae, Aleyrodinae) in four Atlantic Forest fragments
RESUMO: Bemisia tabaci é conhecida no Brasil desde 1923, relatada em cultivos de algodão, soja, tomate e feijoeiro, promovendo prejuízos econômicos por ser transmissora de viroses. São praticamente inexistentes os trabalhos que analisam sua ocorrência em ambiente florestal. Nesse sentido, o objetivo deste trabalho foi estudar a ocorrência de B. tabaci

18. Bayesian sequential procedure to estimate the viability of seeds Coffea arabica L. in tetrazolium test
ABSTRACT: Tetrazolium tests use conventional sampling techniques in which a sample has a fixed size. These tests may be improved by sequential sampling, which does not work with fixed-size samples. When data obtained from an experiment are analyzed sequentially the analysis can be terminated when a particular decision has been made, and thus, there is no nee

19. Diseño y Evaluación de una Trayectoria Hipotética de Aprendizaje para Intervalos de Confianza basada en Simulación y Datos Reales
Abstract This article discusses the design of a hypothetical learning trajectory to introduce the confidence intervals in a basic university course, from an informal perspective based on the use of data obtained from surveys and samples simulation. The trajectory consists of four activities and was evaluated as part of a first improvement cycle with a group

21. Spatial variability of soil physical-hydric attributes under bovine trampling in agreste of Pernambuco State, Brazil
ABSTRACT. Soils under pastures suffer physical modifications, in greater or lesser intensity, via the action of animal trampling. Thus, the aim was to evaluate the spatial dependence of soil physical attributes under bovine trampling. The trial was performed at Roçadinho Farm, Agreste of Pernambuco, Brazil, in a 40 x 40 m paddock that was managed with conti

22. Geochemical Signature of Amazon Tropical Rainforest Soils
ABSTRACT: Evaluating soil geochemical diversity in the Amazon Basin has been a challenge largely because most study sites have been at the edge of the basin and it is difficult to get samples in such a region. Here we show that even among the most weathered soils, physicochemical soil properties express lithology. Our results are based on topsoil samples col
