Maintenance of a high photosynthetic performance is linked to flooding tolerance in citrus
Citrus trees have been considered as flooding-sensitive although important differences in tolerance among species have been reported. The tolerance to flooding has been linked to optimal photosynthetic performance in other ...
Modulation of the antioxidant system in citrus under waterlogging and subsequent drainage
Soil flooding induces an impairment of the photosynthetic system that often leads to an accumulation of reactive oxygen species (ROS) in plant tissues. Moreover, flooding release by drainage can cause a sudden oxygen burst ...
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 ...
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 ...
Improved polyHEMA-DAQ films for the optical analysis of nitrite
A series of crosslinked poly(2-hydroxyethyl methacrylate) films containing 1,2-diaminoantraquinone (DAQ) have been synthesized and characterized spectroscopically by FT-IR and UV-vis. Their response towards nitrite anion ...
Efficient retrieval of ontology fragments using an interval labeling scheme
Nowadays very large domain ontologies are being developed in life-science areas like Biomedicine, Agronomy, Astronomy, etc. Users and applications can benefit enormously from these ontologies in very different tasks, such ...
Drift-flux model in a sub-channel of rod bundle geometry
In view of the practical interest of the drift-flux model for two-phase flow analysis, the distribution parameter and drift velocity constitutive equations have been obtained for subcooled boiling flow in a sub-channel of ...
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) ...
User-assisted simplification method for triangle meshes preserving boundaries
This paper proposes a user-assisted mesh simplification method applied to CAD models converted to triangle meshes. This work offers the possibility of simplifying each subobject independently and at different levels of ...
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 ...
