Supramolecular solvent-based microextraction of ochratoxin A in raw wheat prior to liquid chromatography-fluorescence determination
(Elsevier, 2010)
A supramolecular solvent made up of reverse micelles of decanoic acid, dispersed in a continuous phase
of THF:water, was proposed for the simple, fast and efficient microextraction of OTA in wheat prior
to liquid ...
Coacervative extraction of Ochratoxin A in wines prior to liquid chromatography/fluorescence determination
(Elsevier, 2008)
Coacervates made up of reverse micelles of decanoic acid were assessed as a new strategy
for the simplification of wine sample treatment in the determination of Ochratoxin A (OTA).
Simultaneous extraction/concentration ...
Analysis of two alternative organophosphorus flame retardants in electronic and plastic consumer products: Resorcinol bis-(diphenylphosphate) (PBDPP) and bisphenol A bis (diphenylphosphate) (BPA-BDPP)
(Elsevier, 2014)
Following the phase-out of polybrominated diphenyl ethers (PBDEs), organophosphorus flame retardants (PFRs) are increasingly used as alternative flame retardants in many products. Data on the presence of two alternative ...
In Vitro Activity of Tedizolid against Mycobacterium tuberculosis
(American Society for Microbiology, 2019)
Tedizolid is a novel oxazolidinone with activities against Gram-positive microorganisms, including mycobacteria. We studied the in vitro activity of tedizolid against 120 Mycobacterium tuberculosis strains, including ...
Text mining in education
(Wiley, 2019)
The explosive growth of online education environments is generating a massive volume of data, specially in text format from forums, chats, social networks, assessments, essays, among others. It produces exciting challenges ...
Subgroup Discovery in MOOCs: A Big Data Application for Describing Different Types of Learners
(Taylor & Francis, 2019)
The aim of this paper is to categorize and describe di erent types of learners in mas-
sive open online courses (MOOCs) by means of a subgroup discovery approach based
on MapReduce. The nal objective is to discover ...
Direct probe atmospheric pressure photoionization/atmospheric pressure chemical ionization high-resolution mass spectrometry for fast screening of flame retardants and plasticizers in products and waste
(Springer, 2014)
In this study we develop fast screening methods for flame retardants and plasticizers in products and waste based on direct probe (DP)-atmospheric pressure photoionization (APPI) and atmospheric pressure chemical ionization ...
A Novel Brominated Triazine-based Flame Retardant (TTBP-TAZ) in Plastic Consumer Products and Indoor Dust
(ACS, 2014)
The presence of a novel brominated flame retardant named 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) is reported for the first time in plastic parts of consumer products and indoor dust samples. TTBP-TAZ ...
Phi-Parabolicity and the Uniqueness of Spacelike Hypersurfaces Immersed in a Spatially Weighted GRW Spacetime
(Springer, 2018)
In this paper, we extend a technique due to Romero et al. establishing sufficient conditions to guarantee the parabolicity of complete spacelike hypersurfaces immersed in a weighted generalized Robertson–Walker spacetime ...
Interactive multi-objective evolutionary optimization of software architectures
(Elsevier, 2018)
While working on a software specification, designers usually need to evaluate different architectural alternatives to be sure that quality criteria are met. Even when these quality aspects could be expressed in terms of ...
