Acute reactions to the haemodialysis membrane have been reported as early as 1975 [1]. Because their severity is usually mild, their frequency is probably widely underestimated. However, these reactions may occasionally be life-threatening [2]. The aetiological mechanisms of these reactions are multiple, the best characterized being allergy to ethylene oxide and combined exposure to the polyacr...

The encapsulation of graphite-type carbon wires in the regular, 3-nanometer-wide hexagonal channels of the mesoporous host MCM-41 is reported. Acrylonitrile monomers are introduced through vapor or solution transfer and polymerized in the channels with external radical initiators. Pyrolysis of the intrachannel polyacrylonitrile results in filaments whose microwave conductivity is about 10 times...

Formation mechanisms of single, twin and double hypernuclei from Ξ− absorption at rest on C are investigated with a refined microscopic transport model that incorporates the recently developed quantal Langevin treatment into antisymmetrized molecular dynamics. With a choice of the fluctuation strength that describes dynamical fragmentation processes in the p + C reaction at 45 MeV quite well, t...

The present knowledge about hadrons produced in relativistic heavy ion collisions is compatible with chemical freeze-out happening when the energy density divided by the particle density reaches the value of 1 GeV. This observation is used to determine the energy dependence of the chemical freeze-out parameters Tch and μ ch B for beam energies varying between 1 and 200 A·GeV. The consequences o...

We report photoluminescence measurements on In0:25Ga0:75As/GaAs quantum well and dots grown on (1 1 1)B GaAs substrate in high magnetic ®elds up to 45 Tesla. A well-de®ned PL line with full width at half maximum of approximately 5.5 meV is observed. From an analysis of the zero ®eld transition energy, we point out the importance of an internal piezoelectric ®eld. By analyzing the diamagnetic sh...

BACKGROUND Over the centuries, the world has witnessed alcohol use as a common phenomenon among the male population. Owing to the vulnerability of women towards alcohol and its possible consequences on women as well as children when pregnant or lactating mothers drink alcohol, there is utmost need to know the alcohol use among this population. The study sought to assess alcohol use among the Ne...

The acceleration of ions from ultrathin (10-100 nm) carbon foils has been investigated using intense (∼6×10^{20} W  cm^{-2}) ultrashort (45 fs) laser pulses, highlighting a strong dependence of the ion beam parameters on the laser polarization, with circularly polarized (CP) pulses producing the highest energies for both protons and carbons (25-30  MeV/nucleon); in particular, carbon ion energi...

Primary and leakage x-ray spectra for typical clinical accelerators have been calculated using the EGS Monte Carlo code for 3 energies (6, 10 and 25 MeV) and 4 angles (0 degree, 45 degrees, 90 degrees and 135 degrees). Broad-beam transmission curves have been calculated for ordinary concrete using the MORSE program with the EGS spectra as input. A simple analytical model, which is shown to agre...

We report an experimental study of a planar organic-inorganic microcavity consisting of a porous silicon distributed Bragg reflector, a single layer of acridina orange as active material and a top aluminum reflector. By tuning the cavity resonance energy around the maximum of the organic material photoluminescence, we found an intense emission and a spectral narrowing of the emission band to ab...
