Sampling effort and information quality provided by rare and common species in estimating assemblage structure
(2020-03-01)
Reliable biological assessments are essential to answer ecological and management questions but require well-designed studies and representative sample sizes. However, large sampling effort is rarely possible, because it ...
Evaluation of medicinal plant decomposition efficiency using microwave ovens and mini-vials for Cd determination by TS-FF-AAS
(Springer WienViennaAustria, 2005)
Monitoring of biological variables in Chironomus sancticaroli culturing as test organism
(Sao Paulo: ABEN, 2011, 2014)
A sensitive method for cadmium determination using an on-line polyurethane foam preconcentration system and thermospray flame furnace atomic absorption spectrometry
(Japan Soc Analytical ChemistryTokyoJapão, 2004)
Mechanised flow system for on-line microwave digestion of food samples with off-line catalytic spectrophotometric determination of cobalt at ng l(-1) levels
(Royal Soc ChemistryCambridgeInglaterra, 1999)
Genetic and phenotypic diversity in 2000 years old maize (Zea mays L.) samples from the Tarapacá region, Atacama Desert, Chile
(Public Library of Science, 2019)
The evolution of maize (Zea mays L.) is highly controversial given the discrepancies related to the phenotypic and genetic changes suffered by the species, the incidence of human groups and the times in which these changes ...
Polyurethane foam as a sorbent for continuous flow analysis: preconcentration and spectrophotometric determination of zinc in biological materials
(1998)
A simple and accurate procedure was developed to preconcentrate and determine zinc in biological matrices. A polyurethane foam (PUF) minicolumn was used for the first time for on-line preconcentration. This system was ...
Determination of mercury in biological samples by cold vapor atomic absorption spectrometry following cloud point extraction with salt-induced phase separation
(2007)
Method development for the pre-concentration of mercury in human hair, dogfish liver and dogfish muscle samples using cloud-point extraction and cold vapor atomic absorption spectrometry is demonstrated. Before the extraction, ...
Characterization and biological activity of Bacillus thuringiensis isolates that are potentially useful in insect pest control
(IntechOpen, 2012)
The current study shows a screening of 490 samples from 40 different agricultural environments in Argentina for B. thuringiensis strains that exhibited toxicity against Lepidoptera. Fourteen strains of B. thuringiensis ...
