(Universidade Federal de São Carlos, 2014-11-26)
Currently there are about 35.6 million people diagnosed with Alzheimer's
disease (AD) in the world, and it is expected that this number will double by 2050.
Causes of Alzheimer's disease are not yet known, but their ...
Estudo químico das flores de Hortia oreadica (Rutaceae)
(Universidade Federal de São Carlos, 2018-07-27)
The present work describes the analysis of apolar and polar extracts from flowers of Hortia oreadica, a species of the family Rutaceae. Since these flowers had not been widely studied, and due to the chemosystematic value ...
Desenvolvimento de método analítico com emprego da espectrometria de absorção atômica para a determinação de Cd, Fe, Pb e Zn em amostras de interesse alimentício
(Universidade Federal de São Carlos, 2008-07-31)
Analytical chemistry plays a fundamental role in proposing fast and reliable procedures to analyze food samples. Proper selection and introduction of complementary foods reduces the vulnerability to micronutrient deficiencies. ...
Potencialidades das técnicas com fonte de plasma e da espectrometria de absorção atômica em forno de grafite de alta resolução com fonte contínua para análise de fertilizantes
(Universidade Federal de São Carlos, 2018-04-26)
Each year, Brazil sets records on agricultural productivity, which significantly increases the use of fertilizers in crops to provide the essential nutrientes. However, fertilizers can also be sources of toxic elements ...
Determinação sequencial rápida de As e Sb, Bi e Pb por espectrometria de absorção atômica com geração de hidretos
(Universidade Federal de São Carlos, 2012-03-22)
In this study it was developed two systems, one for the fast sequencial determination of As and Sb and other for Bi and Pb using flame atomic absorption spectrometry with hydride generation. To optimize the system for the ...
