The White Dwarf Luminosity Function: The Shape of Things to Come

We describe a new survey for cool white dwarfs that supplements Sloan Digital Sky Survey photometry with USNO proper motions and followup spectroscopy. To date we have discovered and spectroscopically confirmed 80 new moderate temperature and cool white dwarfs. We have also found a handful of high-velocity white dwarfs and we expect a sizable fraction of these to be thick disk or possibly halo objects. Our survey is designed to find 104 new white dwarfs, although only 60 will be among the faintest white dwarfs (MV 16), where most of the age-sensitivity resides. We discuss an extension of our survey to V 22

Hydatid cyst disease of the lung as an unusual cause of massive hemoptysis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Echinococcosis and/or hydatidosis is one of the most important zoonotic diseases in the world. In Turkey, echinococcosis is an endemic disease, however, hydatid disease of the lung is uncommon and usually caused by <it>Echinococcus granulosus</it>.</p> <p>Case presentation</p> <p>In this report we describe a 17-year-old male patient who presented with massive hemoptysis due to hydatid disease of the lung.</p> <p>Conclusion</p> <p>Although it is one of the less common causes of massive hemoptysis, hydatid disease of the lung requires greater attention in countries, such as Turkey, in which hydatid cyst disease is common.</p
