Characterization of thin plastic foils for applications in X-ray optics technology

2007

Thin plastic foils are being investigated to build shell optics for X-ray telescopes. Compared to polished glass optics, the advantage is in terms of increased collecting area, light weight and lower cost. Plastic material is also desirable to allow deformation into a complete surface of revolution. We collected plastic materials of common use for industrial applications and also specialty materials developed for the electronic industry. A comparative study was then performed to evaluate the optical quality of the selected plastic films. Surface analysis was carried out with topographic instruments to investigate the microroughness of our samples at different scan lengths. Preliminary resul…

Nuove dipendenze del terzo millennio: l'utilizzo di steroidi anabolizzanti come sostanza d'abuso

2005

Obiettivo. L'abuso di sostanze anabolizzanti si sta configurando come un problema di rilevanza psicosociale. L'uso di steroidi anabolizzanti in questi ultimi anni si è spostato dalla pratica sportiva professionale allo sport amatoriale e ad ambiti occupazionali particolari (buttafuori, modelli, ect.). La letteratura indica l'assuntore di steroidi come un poliassuntore che mette in atto condotte pericolose e aggressive per sé e per gli altri. L'obiettivo di questo studio è indagare le abitudini, le condotte di vita e il profilo psicologico di un gruppo di soggetti che frequentano centri sportivi nella città di Palermo (Italia), per verificare come l'utilizzo sconsiderato di sostanze anaboliz…

Subarachnoid Haemorrhage-Incidence of Hospitalization, Management and Case Fatality Rate-In the Silesian Province, Poland, in the Years 2009-2019.

2022

Little is known about the epidemiology of subarachnoid haemorrhage (SAH) in Poland, and until now no such research has been conducted for Silesia, which is the second largest province with circa 4.5 million inhabitants. Therefore, the current study was done to assess the data on SAH in the Silesian Province, Poland. The study was based on the data obtained from the administrative databases of the only public health insurer in Poland (the National Health Fund, NHF) from 2009 to 2019. The SAH cases were selected based on primary diagnosis coded in ICD-10 as I60. The total number of SAH cases was 2014 (41.8% men, 58.2% women). The number of SAH hospitalizations decreased from 199 in 2009 to 16…

Divergent Patterns and Trends in Breast Cancer Incidence, Mortality and Survival Among Older Women in Germany and the United States

2020

Background: Breast cancer treatment has changed tremendously over the last decades. In addition, the use of mammography screening for early detection has increased strongly. To evaluate the impact of these developments, long-term trends in incidence, mortality, stage distribution and survival were investigated for Germany and the United States (US). Methods: Using population-based cancer registry data, long-term incidence and mortality trends (1975&ndash
