Predator trophic guild assignment : the importance of the method of diet quantification
(Soc Natl Protection Nature Acclimatation France, 2000-04)
We quantitatively assessed the effect of three methods of diet quantification (MDQ) (based on frequency of occurrence of prey, dry weight of prey remains, or estimation of fresh biomass ingested) on guild classification ...
Shrub biomass estimation in the semiarid Chaco forest: a contribution to the quantification of an underrated carbon stockShrub biomass estimation in the semiarid Chaco forest: a contribution to the quantification of an underrated carbon stock
(Edp SciencesEdp Sciences, 2013-03)
Abstract & Context The quantification of biomass of woody plants is at the basis of calculations of forest biomass and carbon stocks. Although there are well-developed allometric models for trees, they do not apply ...
Plasmonic sensing through bioconjugation of Ag nanoparticles: Towards the development of immunoassays for ultralow quantification of antigens in colloidal dispersions
(VBRI PRESS, 2018-06)
The combination of the optical properties of silver nanoparticles with some of the tool-kits of the wide spread used ELISA method for antigen quantification immunoassays, give rise to an enzyme free, low cost, fast and ...
Automatic quantification of the LV function and mass: A deep learning approach for cardiovascular MRI
(Elsevier, 2019-02)
Objective: This paper proposes a novel approach for automatic left ventricle (LV) quantification using convolutional neural networks (CNN). Methods: The general framework consists of one CNN for detecting the LV, and another ...
Multi-walled carbon nanotubes functionalized with bathocuproinedisulfonic acid: Analytical applications for the quantification of Cu(II)
(Springer Heidelberg, 2020-08)
This work reports the successful non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with bathocuproinedisulfonic acid (BCS) and the analytical application of the resulting dispersion (MWCNTs-BCS) to ...
Determination of free and total glycerol in biodiesel by spot analysis
(Elsevier Science, 2020-11)
The importance of alternative fuel production has increased in the lately years, and so has the need of methods of analysis to evaluate their quality. Biodiesel fuel is a valuable substitute to petrodiesel fuel. Among the ...
Aging effect on vanadium oxide hybrid nanotubes
(IOP Publishing, 2019-09)
Vanadium oxides present a rich magnetic phase diagram depending on the oxidation state of the V ions. In particular the vanadium oxide nanotubes (VO x NTs) present several promising perspectives for different technological ...
Quenching of bathocuproine disulfonate fluorescence by Cu(I) as a basis for copper quantification
(Academic Press Inc Elsevier Science, 2002-08)
In this paper we report the up to now ignored fluorescence properties of the specific Cu(I)-chelator bathocuproine disulfonate and their application in assays of total copper and Cu(I). The method is based on the linear ...
