339: HLA-DRB1 allele and DRB1-DQB1 haplotype frequency as prediction criterion for the duration of an unrelated blood stem cell donor search
The impact of HLA-B allele level matching on unrelated stem cell donor transplants in Germany
The peculiar variable V838 Monocerotis
Spectroscopic observations of the peculiar variable V838 Mon
during the period from the second light outburst until the fast dimming
are presented. We describe high resolution high
spectra obtained a day before the second light maximum and low resolution
spectra covering the whole period. The temporal
run of intensities and radial velocities of various lines
is presented. Using \ion{Na}{i} D
IS lines we determine the reddening distance of V838 Mon kpc, and
kinematic distance kpc. We estimate that V838 Mon is slightly metal
deficient but otherwise has a quite solar-like chemical composition except
for enhanced abundances of Li, Ba and La
