We present the results of a monitoring campaign of three eclipsing high-mass X-ray binaries (HMXBs: SMC X−1, LMC X−4 and Cen X−3). Highresolution VLT/UVES spectra are used to measure the radial velocities of these systems with high accuracy. We show that the subsequent mass determination of the neutron stars in these systems is significantly improved and discuss the implications of this result.

INTRODUCTION The purpose of our study was to compare the cost-effectiveness of four strategies using components of 1% Or Less to promote population-based behavior change. 1% Or Less is a mass-media campaign that encourages switching from high-fat (whole or 2%) to low-fat (1% or skim) milk. Using a quasi-experimental design, campaigns were previously conducted in four West Virginia communities u...

The unique object SS433 is brieey reviewed with particular reference to the part played by the stellar wind ejected by the early type companion star. The aims of this observational campaign are described and the theory of the mass loss rate measurements explained. VLBA 1.6 GHz maps are presented as well as preliminary 23 GHz VLA and MERLIN maps. Mass loss rates of around 510 ?6 M yr ?1 are foun...

The estimation of benzo(a)pyrene (BaP) concentrations in ambient air is very important from an environmental point of view especially with the introduction of the Directive 2004/107/EC and due to the carcinogenic character of this pollutant. A sampling campaign of particulate matter less or equal than 10 microns (PM10) carried out during 2008-2009 in four locations of Spain was collected to det...

The study assessed whether a mass media campaign could encourage women who were overdue for a Papanicolaou (Pap) test to have one, without prompting unnecessary early re-screening. A telephone survey of a representative sample of 1000 Victorian women aged 25-65 years assessed recall of the advertisement and intention to act after seeing it. The television advertisement was recalled by 61.5% of ...
