Environmental pollution by heavy metals is currently a problem of great concern for human health. In this context, this study aims to contribute with the synthesis and characterization of chitosan functionalized with three ...

This work aims to investigate the possible use of the palm kernel cake powder (Elaeis guineensis Jacq.) as corrosion inhibitor for ASTM 1020 carbon steel in acidic media (0.5 mol L−1 HCl). The investigation was carried ...

A segmentação de imagens é uma das primeiras etapas dentro do arcabouço para processamento de cenas. Entre as principais técnicas existentes destacamos a binarização baseada em histograma, que devido a simplicidade de ...

This work aims to develop a mathematical model for computing the distribution of temperature, O2, and CO2 in the human body, depending on the ambient conditions. The body is divided into segments, including layers of tissues ...

This paper tests whether consumer co-creation claims affect consumer responses, given context information related to the product category performance. The hypothesis is that when there is negative context information related ...

Biodiesel is an alternative biodegradable and non-toxic fuel, with a low emission profile and capable of reducing significantly the level of carcinogenic pollutants released into the atmosphere. A newly designed nano-biocatalyst ...

The hydration and isomerization of the biomass turpentine have been studied in the presence of Purolite CT175. The ion exchange resin catalyst was active for hydration and selective for producing terpenic alcohols, with a ...

This paper presents the electrical behavior at high temperature-range of the effects presents in the non-standard gate layout style for MOSFETs, in which they are capable to boost the electrical performance in relation to ...

This work presents the experimental temperature dependence evaluation of the pseudo-resistor piecewise linear (PWL) macromodel, for temperature ranging from 300 to 333 K. The studied macromodel is based on the PWL methodology ...
