The role of the reaction force to characterize local specific interactions that activate the intramolecular proton transfers in dna basis
(AMERICAN INSTITUTE OF PHYSICS, 2004)
Tissue-specific inhibition and recovery of esterase activities in Lumbricus terrestris experimentally exposed to chlorpyrifos
(ELSEVIER, 2010)
Exposure and effect assessment of organophosphate (OP) pesticides generally involves the use of
cholinesterase (ChE) inhibition. In earthworm, this enzyme activity is often measured in homogenates
from the whole organism. ...
Metal fractionation in sludge from sewage UASB treatment
(2017-05-15)
This study evaluates the trace metal composition and fractionation in sludge samples from anaerobic sewage treatment plants from six cities in Brazil. Ten metals were evaluated: Ni, Mn, Se, Co, Fe, Zn, K, Cu, Pb and Cr. ...
Development of an absolute method for efficiency calibration of a coaxial HPGe detector for large volume sources
(Elsevier, 2015)
In this work an absolute method for the determination of the full energy peak efficiency of a gamma spectroscopy system for voluminous sources is presented. The method was tested for a high-resolution coaxial HPGe detector ...
Esterase activities of indigenous lactic acid bacteria from Argentinean goats' milk and cheeses
(Elsevier, 2007-08)
Esterase activities of indigenous lactic acid bacteria isolated from goats' milk and cheese were investigated. All of the strains exhibited esterase activity on α-naphthyl derivative of fatty acids of 2-6 carbon atoms. ...
