Popular Abstract in Swedish Hantering av risker i företag och organisationer har haft en lång och komplicerad historia. På åttiotalet, och i början av nittiotalet, var uppfattningen att om en olycka inträffade i en organisation, som påstods vara nära nog perfekt, måste det bero på ”den mänskliga faktorn”, dvs. att en eller flera medarbetare inte gjorde som de borde ha gjort. Orsakerna till olyckaIntroduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error. The cause for the accidents was desc

Powerformer(R), a new high-voltage generator, was presented by ABB. It offers a direct connection to the power network without the need for a step-up transformer. In a sense, Powerformer incorporates into one unit the functions of both the conventional generator and the step-up transformer. Thanks to its ability to generate electricity at transmission voltage levels, a power plant utilizing Powerf

With the attempts to increase power, efficiency and thrust, modern gas turbines operate with combustor outlet temperatures of 1800-2000 K, which are far beyond the allowable metal temperatures. Turbine blades are exposed to these high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is importan

Local blood flow in the thigh was measured with 133Xe clearance technique in eight male distance runners after compression with a foam rubber compress and a standard elastic bandage. Two degrees of compression were tested, and an initial experiment with rested subjects was followed by a similar experiment immediately after running. Maximum compression exerted a cutaneous pressure of 85 (+/- 8) mm

Signs of Flesh: Institution and Body in Accounts of Paranoia (Notes on Schreber and Fabian) As the call for paper to this conference aptly states, phenomenology holds that "[c]onsciousness [is] dependent on a body and a world, which bestow it with existence and meaning." My take on this phenomenologist axiom would be to suggest a complementary thesis, something like: "The world (understood as the

In this note I would like to give some personal views on the relevance of bandstructure treatments of narrow-band systems. At first sight one might think that bandstructure theory is not a very appropriate framework for quasi-localized electrons. Nevertheless, it has been found that density-functional (DF) theory in its modern form gives a rather impressive description of ground-state properties f
