Desarrollo y validación de un instrumento para la evaluación del comportamiento sexual de los transexuales: el CSTM
(Asociación Española de Psicología Clínica y Psicopatología, 2012)
Scientific literature presents a vacuum as to the self-perception of transsexuals about their sexuality. Most research is limited to the sex reassignment surgery consequences in their orgasmic capacity. Given the scarcity ...
A DFT study of methanol dissociation on isolated vanadate groups
Molecular and dissociative adsorption processes of methanol on isolated vanadate groups have been studied by means of density functional theory calculation at the B3LYP computing level. The catalyst is represented by an ...
Flow structure of gas-liquid two-phase flow in an annulus
The flow structure of gas-liquid two-phase flow in vertical annulus channel has been investigated. The inner and outer diameters of the annular channel were 19.1 and 38.1 mm, respectively. The total height of the test ...
Densification of monomodal quartz particle beds by tapping
A study has been undertaken to determine how the mean particle size of monomodal quartz particle beds and the bed preparation method affect initial and final bed apparent density and the kinetics of densification by tapping. ...
Excitons diffusion and singlet-triplet occupation at high Bose-Einstein chemical potential
The paper investigates the bosonic aspects of exciton statistics in non-equilibrium situations. A kinetic model is formulated treating the excitons in different states as chemical species, using a master equation consistent ...
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 ...
Perimeter leakage current in polymer light emitting diodes
Observation of leakage current paths through the device perimeter in standard poly(phenylene vinylene)-based light-emitting devices is reported. Perimeter leakage currents govern the diode performance in reverse and low ...
Amidation through carbamates
N-Alkyl carbamates of primary amines are easily converted into amides under treatment with Grignard reagents. Consequently, primary amines can be converted into amides in a one-pot reaction through carbamate protection and ...
