METHODS A retrospective population based case-control study using the data derived from the Finnish Medical Birth Register for the years 1991-2010. A total populat...
A design for a canopy trap for collecting horse flies is described. The collecting heads can easily be changed since the collar is fixed in place and supports the trap. The collar allows an unobstructed pathway to the collecting head. The center pole has a sliding steel rod that allows adjustment of canopy height upon installation in one operation.
This paper studies the deterrent e↵ect of criminal enforcement on white-collar criminal activities.

Cross-section...

The aim of the study was to examine the associations between several occupational indicators and total, occupational and leisure-time sitting. METHODS Cross-sectional se...
STUDY DESIGN In vitro biomechanical study. OBJECTIVE Our objective was to determine the effectiveness of cervical collars and cervicothoracic orthoses for stabilizing clinically relevant, experimentally produced cervical spine injuries. SUMMARY OF BACKGROUND DATA Most previous in vitro studies of cervical orthoses used a simplified injury model with all ligaments transected at a single spin...
