In this paper I use longitudinal data to study the effects of changes in industrial composition on wages during the 1970s and 1980s. I find that over ten year periods, workers who are initially in industries that subsequently expand have faster wage growth. Also, wage growth is strongly related to employment changes in industries the individual is likely to move to. These effects are larger dur...

OBJECTIVE We aimed to assess the role of Magnetic Resonance Imaging (MRI) and X-Ray in the evaluation of response to radiosynovectomy (RS) in patients with hemophilic arthropathy. MATERIAL AND METHODS Eleven patients who suffered from hemophilic arthropathy with a mean age of 11.7 (range between 7-15) were included in this study. 148-185 MBq Yttrium 90 silicate (Y-90) was administered intraar...
Abstract Cement is an inexpensive and relatively easily manageable material that used as a last barrier for nuclear waste disposal. Under these conditions, the cement in contact with low radiation doses, but there distinct possibility of being contaminated radioactive products. Of particular concern medium lived half-life product $$\mathrm {{}^{90}Sr}$$ <mml:math xmlns:mml="http://www.w3.org/19...
To develop an approach to utilizing continuous statistical information within the Dempster- Shafer framework, we combine methods proposed by Strat and by Shafero We first derive continuous possibility and mass functions from probability-density functions. Then we propose a rule for combining such evidence that is simpler and more efficiently computed than Dempster's rule. We discuss the relatio...
