Abstract Introduction Hormone Replacement Therapy (HRT) use has recently been a topic of debate amongst clinicians. The discussion most prevalent in the fields gynecology, urology, and endocrinology. Current research suggests HRT can prevent development lethal diseases such as myocardial infarction, osteoporosis, diabetes mellitus, Alzheimer's disease, Parkinson’s genitourinary syndrome menopau...

The recently discovered new class of sdB pulsators (sdBV) offers a powerful possibility for the investigation of their interior and thus their evolutionary history. The first step towards applying asteroseismologic tools is the identification of pulsation modes. The best target for such an investigation is PG 1605+072 because of its outstanding properties among the sdBVs: it is the brightest ob...

Four members of the new class of pulsating sdB stars are analysed from Keck HIRES spectra using NLTE and LTE model atmospheres. Atmospheric parameters (Teff , log g, log(He/H)), metal abundances and rotational velocities are determined. Balmer line fitting is found to be consistent with the helium ionization equilibrium for PG1605+072 but not so for PG 1219+534 indicating that systematic errors...

We propose a priority-pricing scheme for zonal access to the electric power grid that is uniform across all buses in a zone. The Independent System Operator (ISO) charges bulk power traders a per unit ex ante transmission access fee. The zonal access fee serves as an access insurance premium that entitles a bulk power trader to either physical injection of one unit of energy or a compensation p...
