In arid and semiarid areas, the interplant spaces are usually covered by physical and biological soil crusts. These crusts, though representing an almost negligible portion of the soil profile, have a number of crucial r...

The characteristics of fermentation and aerobic stability were evaluated in corn silage inoculated with different doses of Lactobacillus buchneri. The whole corn plant (300 g/kg DM) was ensiled in quadruplicate laborator...

Fermentation and aerobic stability were evaluated in high-moisture corn (HMC) silage inoculated with different levels of Lactobacillus buchneri. The HMC composed of 654 g/kg dry matter (DM) was ensiled in quadruplicate l...

The objective of this study was to evaluate the chemical composition, fermentation patterns and aerobic stability of sugarcane silages with addition of amino acid production (monosodium glutamate) by-product (APB) and mi...

The objective of this study was to evaluate the CombiScope FTIR equipment based on Fourier Transform Infrared methodology (FTIR), to assess the content of milk urea nitrogen (MUN) in Brazil. Repeatability and reproducibi...

A novel method for analysis of biodiesel by electrothermal atomic absorption spectrometry is described. This analytical strategy involves sample preparation as emulsions for routine and reliable determination of Cd and H...

The aim of this work was to synthesize and to characterize new pH-sensitive hydrogels that can be used in the controlled release of drugs, useful for dermal treatments or ophthalmology's therapies. Copolymers containing ...

We report low-temperature transport measurements through a double-quantum-dot device in a configuration where one of the quantum dots is coupled directly to the source and drain electrodes, and a second (side-coupled) qu...

New complexes of platinum and palladium were isolated with 2,4-dinitrophenylhydrazine (2,4-DNPH). These complexes were characterized and the results shown that the ligand is coordinated to platinum or palladium by the ba...

El uso expandido a nivel mundial, la persistencia y toxicidad del herbicida atrazina y sus metabolitos llevaron a que se conviertan en uno de los contaminantes más comunes en aguas superficiales y subterráneas, excedie...
