Returns to education: epistemological problems of quantification and its impact on the formulation of policies
(Universidad Veracruzana, 2009-03)
The development of researches which approach the study of returns to education in order to influence on the making of decisions is frequent. There are conventional procedures to quantify them and to grant scientism to the ...
Isomeric differentiation and quantification of alpha, beta-amino acid-containing tripeptides by the kinetic method: alkali metal-bound dimeric cluster ions
(Elsevier Science BvAmsterdamHolanda, 2004)
Ferromagnetic resonance for the quantification of superparamagnetic iron oxide nanoparticles in biological materials
(DOVE MEDICAL PRESS LTD, 2010)
The aim of the present work is the presentation of a quantification methodology for the control of the amount of superparamagnetic iron oxide nanoparticles (SPIONs) administered in biological materials by means of the ...
Fluorometric quantification of green fluorescent protein in tobacco leaf extracts
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2009)
Standardless quantification methods in electron probe microanalysis
(Pergamon-Elsevier Science Ltd., 2014-11)
The elemental composition of a solid sample can be determined by electron probe microanalysis with or without the use of standards. The standardless algorithms are quite faster than the methods that require standards; they ...
Characterization and Quantification of the Compounds of the Ethanolic Extract from Caesalpinia ferrea Stem Bark and Evaluation of Their Mutagenic Activity
(Mdpi Ag, 2014-10-01)
Caesalpinia ferrea Martius has traditionally been used in Brazil for many medicinal purposes, such as the treatment of bronchitis, diabetes and wounds. Despite its use as a medicinal plant, there is still no data regarding ...
High-Performance Liquid Chromatographic Quantification of Flavonoids in Eriocaulaceae Species and Their Antimicrobial Activity
(Molecular Diversity Preservation International-mdpi, 2009-11-01)
Quantification of prepared samples by analysis using high performance liquid chromatography with DAD detection was developed to analyze rutin, 6-methoxyapigenin, and 6-methoxyapigenin-7-O-beta-D-glucopyranoside isolated ...
Dynamics of magneto electro elastic curved beams: Quantification of parametric uncertainties
The objective of this paper is the evaluation of uncertainty propagation associated to several parameters in the dynamics of magneto-electro-elastic (MEE) curved beams. These MEE structures can be employed as imbedded parts ...
Error estimation in environmental DNA targets quantification due to PCR efficiencies differences between real samples and standards
Nowadays, as in the past, our knowledge of microbiology is limited because of the capacity of available technology tools. In recent decades, molecular techniques are playing a central role in the understanding of the ...
