Fluorescence and mass spectrometry studies of the interaction between naproxen and synthetic pseudopeptidic models in organic media
Time-resolved/steady-state fluorescence and mass spectrometry measurements have shown the preferential binding of a non-steroidal anti-inflammatory drug (NSAID) like naproxen 4 to a synthetic pseudopeptidic receptor built ...
Malayaite ceramic pigments: A combined optical spectroscopy and neutron/X-ray diffraction study
Ceramic pigments based on the Cr-doped malayaite structure were synthesized by solid state reaction and characterized by optical spectroscopy and combined X-ray and neutron powder diffraction in order to elucidate the still ...
Temperamental traits in mice(II): Consistency across apparatus
The present study examines the consistency across apparatus of murine activity, anxiety and novelty seeking traits. The activity, anxiety and novelty seeking factor scores extracted from the study of Ibáñez et al. (2007) ...
A QM/MM study of the reaction mechanism for the 3′-processing step catalyzed by HIV-1 integrase
Integrase (IN) is one of the three human immunodeficiency virus type 1 enzymes (HIV-1) essential for effective viral replication. This viral enzyme is involved in the integration of HIV DNA into host chromosomal DNA. In ...
Experimental evaluation of the inter-stage conditions of a two-stage refrigeration cycle using a compound compressor
The aim of the present paper is to detail an analysis, based on experimental data, of the inter-stage working conditions of a two-stage vapour compression facility equipped with a compound compressor, which operates with ...
Synthesis of new chiral imidazolium salts derived from amino acids: their evaluation in chiral molecular recognition
A family of new imidazolium salts derived from natural amino acids has been synthesized and tested for NMR enantiodiscrimination, as chiral shift reagents, of carboxylic acids. These imidazolium receptors contain different ...
Direct and indirect effects of education on job satisfaction: A structural equation model for the Spanish case
Empirical literature has traditionally analyzed the effect of education on job satisfaction with single-equation models that ignore interrelationships between theoretical explanatory variables. Their results are somewhat ...
Improved efficiency in sensitivity calculations for bioreactor models
Sensitivity functions are a basic tool in the parametric identification of models. They can be used to obtain the gradient needed by optimization algorithms in the estimation of parameters and to calculate the Fisher ...
Generating complex ontology instances from documents
This paper presents a novel Information Extraction system able to generate complex instances from free text available on the Web. The approach is based on a non-monotonical processing over ontologies, and makes use of ...
Differential dorsolateral prefrontal cortex activation during a verbal n-back task according to sensory modality
Functional neuroimaging studies carried out on healthy volunteers while performing different n-back tasks have shown a common pattern of bilateral frontoparietal activation, especially of the dorsolateral prefrontal cortex ...
