Fastighetens gränser

Lantmäteriverket har uttryckt en vision om koordinatbestämda fastighetsgränser, med avsikt att skapa en i gränshänseende korrekt digital registerkarta. Ett förverkligande av visionen skulle kräva en förändring av gällande rätt, eftersom dagens gränssystem bygger på principen att gränsmärken på marken gäller framför andra uppgifter om gränsers sträckning. Hur en eventuell övergång till koordinatbes

The church, the cultural landscape and the extended Middle Ages: The concept of "the extended Middle Ages" is presented, arguing for the integration of Post-Medieval churches as well as medieval ones in the study of society and the cultural landscape.

Reproductive outcome in a cohort of male and female rubber workers: a registry study.

PURPOSE: To investigate whether blue-collar employment in the Swedish rubber industry from 1973 onwards had a negative impact on reproductive health. METHODS: Pairs of mother and child, and triads of father-mother-child were obtained through linkage of a cohort of 18,518 rubber factory employees with the Swedish Population Registry. Birth outcomes were obtained from the Medical Birth Register for

En Fysikbro för kontakter mellan forskare och skola

Skolans undervisning i naturvetenskap kan lägga grunden för intresse och vidare studier inom de naturvetenskapliga och tekniksa ämnena, och strävar också efter att get en god allmänbildning som medborgarkunskap. I oktober 2011 anordnade NRCF ett nationell Fysikbromöte i Göteborg för att bygga broar mellan fysiker och gymnasielärare kring olika frågor.

A vertebral fracture in childhood is not a risk factor for disc degeneration but for Schmorl's nodes: a mean 40-year observational study.

STUDY DESIGN: Observational cohort study. OBJECTIVE: To evaluate by MRI whether a vertebral fracture during childhood is a risk factor for degeneration of adjacent discs. SUMMARY OF BACKGROUND DATA: Several studies infer that trauma is a major cause of disc degeneration. Only 1 study has by magnetic resonance imaging (MRI) evaluated disc degeneration in children with a former thoracic or lumbar ve

Determination of Radiative Lifetimes In Neutral Arsenic Using Time-resolved Laser Spectroscopy In the Vuv Region

Inspired by the recent Hubble Space Telescope first observations of arsenic in an astrophysical object we have determined the natural radiative lifetime of the upper states of two of the three resonance lines of As I. Short pulse laser excitation at 193.7 and 197.2 nm was achieved using different non-linear optical mixing schemes. Using time-resolved spectroscopy we obtain tau(4p(2)5s P-4(3/2))=4.
