Use of blanks to determine in vitro net gas and methane production when using rumen fermentation modifiers
(ELSEVIER SCIENCE BV, 2011)
Blanks (flasks without substrate containing only inoculum and medium) are used in vitro to correct for gas. CH(4) and residual organic matter (OM) fermented in inoculum. However inclusion of rumen fermentation modifiers ...
Standard addition calibration: Is it enough for an analytical result estimation?. Spectrophotometric experiments for analyte quantitation in real samples
(Research Trends, 2021-12)
Analytical method validation is the first step for quantitative analysis, and both validation and quantitation are usual and fundamental tasks in analytical work; hence it is extremely important to perform them in the most ...
Advanced and tailored applications of an efficient electrochemical approach assisted by AsLSSRCOW- rPLS and finding ways to cope with challenges arising from the nature of voltammetric data
(Elsevier, 2015-07)
The use of chemometric data processing is becoming an important part of modern voltammetry. The most challenges arising from voltammetric data are interactions among analytes and the background interferents which may cause ...
Behavioral, modeling, and electrophysiological evidence for supramodality in human metacognition
(Society for Neuroscience, 2018-01)
Human metacognition, or the capacity to introspect on one’s own mental states, has been mostly characterized through confidence reports in visual tasks. A pressing question is to what extent results from visual studies ...
Accurate and Precise Zinc Isotope Ratio Measurements in Urban Aerosols
(AMER CHEMICAL SOC, 2008)
We developed an analytical method and constrained procedural boundary conditions that enable accurate and precise Zn isotope ratio measurements in urban aerosols. We also demonstrate the potential of this new isotope system ...

Influência de fatores ambientais de ampla escala na distribuição espacial de moluscos límnicos
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade Animal, 2014-02-14)
This dissertation presents unique approaches about the influence of environmental variables at
different spatial scales (meso and macro regional temperature, rainfall and altitude) (1), and
aquatic and terrestrial factors ...
