Screwdrivers and their use from a Swedish construction industry perspective.

The purpose of this paper is to focus on certain important aspects of screw driver use in occupational work situations, with an emphasis on force exertion and screwdriver use in construction work. Hand tools are involved in many accidents and injuries in the Swedish construction industry. Traditions with in the industry sometimes have a strong influence on what tools are being used and how the work is performed.

Paired analysis of thromboxane and prostacyclin metabolites in urine from healthy mothers and their children.

Eicosanoids have been implicated in the adaptation of the fetal to the neonatal circulation, but biochemical support for an activation of their synthesis in relation to birth has not been presented. We addressed this by assessing in pairs the excretion of two metabolites of thromboxane A2, 11-dehydro-TxB2 (dTx) and 2,3-dinor-TxB2 (Tx-M), and one metabolite of prostacyclin, 2,3-dinor-6-keto-PGF1 a (PGI-M), in the first voided urine from 13 healthy term neonates and in the immediate pre-delivery urine from their respective mothers. The excretion of dTx was higher (p less than 0.
