Chelating properties of humic-like substances obtained from process water of hydrothermal carbonization
(2021-08-01)
Recent studies have shown a new way of producing humic-like substances (HLS) from hydrochar prepared by hydrothermal carbonization of biomass. However, studies of HLS extracted from process water (PW) produced in hydrothermal ...
Humic extracts of hydrochar and Amazonian Dark Earth: Molecular characteristics and effects on maize seed germination
(2020-03-15)
Inspired by the presence of anthropogenic organic matter in highly fertile Amazonian Dark Earth (ADE), which is attributed to the transformation of organic matter over thousands of years, we explored hydrothermal carbonization ...
On weighted inequalities for fractional integrals of radial functions
(Univ Illinois Urbana-champaign, 2011-05)
We prove a weighted version of the Hardy-Littlewood-So- bolev inequality for radially symmetric functions, and show that the range of admissible power weights appearing in the classical inequality due to Stein and Weiss ...
Infraestrutura de compilação para a implementação de aceleradores em FPGA
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2012-11-23)
In recent years, performance improvements in sequential microprocessors have been limited by physical and technological factors. For this reason, alternative approaches for high performance execution have gained importance. ...
