Occupation and cancer - follow-up of 15 million people in five Nordic countries.
We present up to 45 years of cancer incidence data by occupational category for the Nordic populations. The study covers the 15 million people aged 30-64 years in the 1960, 1970, 1980/1981 and/or 1990 censuses in Denmark, Finland, Iceland, Norway and Sweden, and the 2.8 million incident cancer cases diagnosed in these people in a follow-up until about 2005. The study was undertaken as a cohort ...
متن کاملModeling West Antarctic ice sheet growth and collapse through the past five million years
The West Antarctic ice sheet (WAIS), with ice volume equivalent to ~5 m of sea level,1 has long been considered capable of past and future catastrophic collapse.2, 3, 4 Today, the ice sheet is fringed by vulnerable floating ice shelves that buttress the fast flow of inland ice streams. Grounding lines are several hundred meters below sea level and the bed deepens upstream, raising the prospect ...
متن کاملData Mining The Original Data Warehouse: Twenty-Five Years And A Million Lines of SAS Later
The author of MXG Software provides a historical perspective of how and why the SAS System became the pervasive tool for managing and mining of the original data warehouse, the Performance Data Base built from SMF data. The architecture of the MXG implementation is described to show how MXG, currently 911,749 lines of SAS code in 3,011 files (members), executes under MVS, VM, UNIX, OS/2, Window...
متن کاملSeventy-five-million-year-old tropical tetra-like fish from Canada tracks Cretaceous global warming.
Newly discovered fossil fish material from the Cretaceous Dinosaur Park Formation of Alberta, Canada, documents the presence of a tropical fish in this northern area about 75 million years ago (Ma). The living relatives of this fossil fish, members of the Characiformes including the piranha and neon tetras, are restricted to tropical and subtropical regions, being limited in their distribution ...
متن کاملConsiderations for Latitudinal Time-Averaged-Field Palaeointensity Analysis of the Last Five Million Years
Central to palaeomagnetism and geophysics is the assumption that the time-averaged geomagnetic field is approximated by a geocentric-axial-dipole (GAD). In this paper, it is demonstrated through the use of a simple cap model that due to secular variation the time-averaged palaeointensity record will always have a smaller latitudinal dependency than a true GAD field. However, the simple cap mode...
