Rare causes of anemia in liver diseases.

Anemia is a common finding among patients with liver diseases. Patients who suffer from anemia are at a higher risk of liver function decompensation and hospitalization. It affects significantly their quality of life and contributes to mortality.

Measurements of the neutron cross sections of hydrogen and deuterium in H2O-D2O mixtures using the deep inelastic neutron-scattering technique.

We investigated the neutron cross sections of hydrogen and deuterium by means of the deep inelastic neutron-scattering technique in H2O-D2O mixtures. The interest in this work was to examine the anomalous behavior in the hydrogen neutron cross section reported in the past in similar experiments that raised a yet unsettled controversy. The measurements were made at the Bariloche pulsed neutron source (Argentina) in pure H2O and D2O, with mixtures of molar concentrations of deuterium of xD=0.

Search for anomalous effects in H2O/D2O mixtures by neutron total cross section measurements.

We investigate anomalies ascribed to quantum entanglement phenomena recently reported in deep inelastc neutron scattering (DINS) measurements by an independent neutron technique on H(2)O/D(2)O mixtures. We performed transmission experiments to study several liquid H(2)O/D(2)O mixtures at room temperature in the epithermal energy range. We obtain the total cross sections of the mixtures, which are in agreement with the expected results according to the tabulated values within a 0.

Quantum effects on liquid dynamics as evidenced by the presence of well-defined collective excitations in liquid para-hydrogen.

The origin of the well-defined collective excitations found in liquid para-H2 by recent experiments is investigated. The persistence of their relatively long lifetimes down to microscopic scales is well accounted for by calculations carried out by means of path-integral-centroid molecular dynamics. In contrast only overdamped excitations are found in calculations carried within the classical limit.
