Total to Selective Extinction Ratios and Visual Extinctions from Ultraviolet Data

We present determinations of the total to selective extinction ratio RV and visual extinction AV values for Milky Way stars using ultraviolet color excesses. We extend the analysis of Gnaciński and Sikorski (1999) by using non-equal weights derived from observational errors. We present a detailed discussion of various statistical errors. In addition, we estimate the level of systematic errors by considering different normalization of the extinction curve adopted by Wegner (2002). Our catalog of 782 RV and AV values and their errors is available in the electronic form on the World Wide Web.

Procedures regarding expired medicinal products - select legal issues

This article discusses the problem of pharmaceutical waste as hazardous to both the environment and human health. Persistently low ecological awareness in society, coupled with a small number of reception places where such waste can be delivered, prevent it from adequate segregation. In effect, together with other household waste, it is sent to municipal landfills, which in most cases lack the suitable protection measures necessary to prevent negative environmental impact. Only recently have medicine manufacturers been under an obligation to include in their leaflets a notice of special precautions to be taken during the disposal of unused pharmaceuticals and their waste. At present, a selective collection of medicines constituting hazardous waste from the municipal sector is carried out to a very narrow extent. From the legal standpoint, constructing reception systems for all municipal waste is the obligation of the municipal authorities. A number of pharmacies cooperating with local governments volunteer to participate in the segregation of pharmaceutical waste, providing special containers for medicines that are past their sell-by date. The study also describes procedures for expired psychotropic medicines and narcotics, which due to social reasons present a substantial problem in terms of their disposal. Legal regulations require strict procedures while handling this type of medicine.
