From the Dermatologikum Hamburg: Quiz
A 48-year-old woman presented herself with an erythematous macule on the extensor surface of the right thigh. The lesion had been present for years, but recently the patient noticed some increase in size and changes in the coloration. This had prompted her to see a dermatologist (Figure 1). A biopsy was taken and photomicrographs are presented in Figures 2A-I. What is your diagnosis? Answer and...

متن کاملCool helium-rich white dwarfs from the Hamburg/ESO survey
We present an analysis of 40 cool helium-rich white dwarfs found in the Hamburg/ESO survey. They were selected for follow-up spectroscopy because of their U −B colour below -0.18, the absence of strong absorption lines, and a continuum shape similar to that of a quasar. Effective temperatures for individual stars were determined by fitting model atmospheres of nearly pure helium with a small ad...
متن کاملEfficacy of bomb shelters: with lessons from the Hamburg firestorm.
Shelters for protection against the effects of nuclear weapons are often stated to be useless, largely because of firestorms. Recent models purport to show that nuclear weapons are more likely to cause firestorms than previously thought. These controversial models are based on uncertain assumptions, which are difficult or impossible to test. Regardless of the predictive validity of fire models,...
متن کاملSpectral analysis of sdB stars from the Hamburg Quasar Survey⋆
Abstract. We present the results of a spectral analysis of a large sample of subdwarf B stars selected from followup observations of candidates from the Hamburg Quasar Survey. Fundamental parameters (effective temperature, gravity, and helium abundance) were determined by matching synthetic line profiles calculated from model atmospheres to all hydrogen and helium absorption lines present in th...
