(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2017-03-31)
The poultry industry has the highest share and the highest growth rates in the world agribusiness, Brazil being one of the main producers in this segment as it is the second largest producer of chicken meat in the world ...
Use of tequila vinasses as carbon source and electron donor for biological nitrate removal
(2001)
This paper presents an energy-based small signal method of analyzing low-frequency inter-area oscillations. A comprehensive framework for the analysis of system oscillations is developed based on the analysis of energy ...
Dentin hypersensitivity clinical study comparing LILT and LEDT keeping the same irradiation parameters
(WILEY-V C H VERLAG GMBH, 2010)
Dentin hypersensitivity is a common condition associated with high dental pain. A new LED-based (light emitting diode) light source has been used as an experimental tool in some studies. Purpose: The main objective was to ...
Exploration of liquid chromatographic-diode array data for Argentinean wines by extended multivariate curve resolution
(Elsevier Science, 2014-01-07)
Second-order data were measured using high-performance liquid-chromatography with diode array detection (HPLC-DAD) for a number of wine samples, which were directly injected in the HPLC-DAD system without sample pre-treatment. ...
Analysis of metals and phosphorus in biodiesel B100 from different feedstock using a Flow Blurring® multinebulizer in inductively coupled plasma-optical emission spectrometry
(Elsevier Science, 2014-04)
A simple and fast method for determining the content of Na, K, Ca, Mg, P, and 20 heavy metals in biodiesel samples with inductively coupled plasma optical emission spectrometry (ICP OES) using a two-nozzle Flow Blurring® ...
Modeling of second-order spectrophotometric data generated by a pH-gradient flow injection technique for the determination of doxorubicin in human plasma
(Elsevier Science, 2013-09)
In this paper, the development of a pH-gradient flow-injection method with diode-array spectrophotometric detection combined with extended multivariate curve resolution–alternating least-squares (MCR–ALS) to quantitate ...
Determinação de elementos terras raras por espectrometria de absorção atômica de alta resolução com fonte contínua por chama
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2018-08-29)
In the present work, two methods of determination of rare earth elements by high resolution continuum source flame AAS was developed, being a sequential and a simultaneous method. The sequential method allowed the determination ...
Classificação de genótipos de trigo usando espectroscopia de infravermelho próximo e quimiometria
(Universidade Tecnológica Federal do ParanáCampo MouraoMedianeiraBrasilPrograma de Pós-Graduação em Tecnologia de AlimentosUTFPR, 2019-04-03)
Wheat, Triticum aestivum L., is one of the most important cereal crops, accounting for about 30% of world production. The interactions between wheat genotype and environmental conditions define the quality of the grain and ...
Fourier transform infrared spectroscopy-Partial Least Squares (FTIR-PLS) coupled procedure application for the evaluation of fly attack on olive oil quality
(Elsevier, 2013-01)
A Fourier transform infrared spectroscopy–Partial Least Squares (FTIR–PLS) strategy for the determination of the quality of olive fruits and the respective virgin olive oil (VOO) has been developed. This methodology has ...
Rapid FTIR determination of water, phenolics and antioxidant activity of olive oil
(Wiley VCH Verlag, 2010-10)
A rapid Fourier transformed infrared (FTIR) attenuated total reflectance (ATR) spectroscopic method was applied to the determination of water content (WC), total phenol amount (TP) and antioxidant activity (ABTS.p) of ...
