We report the discovery of two new ZZ Ceti pulsators, LP 133−144 and HE 1258+0123, selected on the basis of model atmosphere fits to optical spectroscopic data. The atmospheric parameters for LP 133−144, Teff = 11, 800 ± 200 K and log g = 7.87 ± 0.05, and for HE 1258+0123, Teff = 11, 410 ± 200 K and log g = 8.04 ± 0.05, place them within the empirical boundaries of the ZZ Ceti instability strip...

The introduction of internet auction has significantly widened the pool of consumers who participate in auctions and increased the number of companies attempting to sell their products in an auction format. Previous empirical research on auctions has focused almost exclusively on the behavior of professional bidders. In this study, we collect data on a large number of internet auctions to explo...

Subgroup analyses of major randomized clinical trials in heart failure are published frequently, but their impact on medical knowledge and practice guidelines has not been previously reported. In a novel analysis, we determined number of citations, impact factors, number of authors, and citations in guidelines of both parent trials and sub-studies; we also qualitatively assessed whether the ana...

To select the most useful evaluative outcome measures for early multiple sclerosis, we included 156 recently diagnosed patients in a 3-year follow-up study, and assessed them on 23 outcome measures in the domains of disease-specific outcomes, physical functioning, mental health, social functioning and general health. A global rating scale (GRS) and the Expanded Disability Status Scale (EDSS) we...

Abstract In this study, the effects of cutting speed, tool geometry, and machining parameters on surface roughness forces in turning Nilo 36 superalloy have been investigated. An experimental design process was made with Taguchi technique. way, optimum values were estimated a small number experiments. The grey correlation analysis method used to determine best parameter levels plausible factors...

The aim of this study was to test i) whether patients having diabetes and ischemic heart disease (IHD), i.e., patients suffering from two chronic diseases, demonstrate a higher degree of chronic stress when compared with patients suffering from IHD alone, and ii) whether suffering from the two chronic diseases results in an elevation in specific elements of the chronic stress concept. A total o...
