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
Neuropeptide Y (NPY) has been shown to be involved in the control of several neuroendocrine functions. Moreover, in animal models, NPY produces behavioral effects that are similar to those induced by anxiolytics. We studied NPY-like immunoreactivity (NPY-LI) in cerebrospinal fluid (CSF) in two primary degenerative dementias, Alzheimer disease (AD, n = 34) and frontotemporal dementia (FTD, n = 22)
The ‘old’ forms of governance have been criticised for being neither sufficiently democratic nor effective. The popularity of ‘new’ modes of governance includes the embracing of values – integral to democratic processes – such as legitimacy, public accountability and trust. By relating parts of this ‘old-vs.-new’ distinction to March & Olsen’s dichotomy of aggregative vs. integrative politica
A new master programme in ergonomics is being developed by the Swedish National Institute for Working life in co-operation with the Institutes of Technology in Linköping and Lund. The course runs at ‘half-speed’ and with extensive use of IT. The course takes advantage of the students’ different professional backgrounds.

We present an exact ab initio theory for describing the motion of interacting electrons through nanoscopic constrictions. Our theory is based on time-dependent density functional theory (TDDFT) and nonequilibrium Green functions. We consider the system electrode-device-electrode initially contacted and in equilibrium, therefore the scheme is thermodynamically consistent. Besides the steady-state r
In his dissertation Blomberg (2004) investigates into how the care manager reform is incorporated into organizational practice in the care of older people in Sweden. He shows that it is made through different lines of argumentations following one another. Through applying neo-institutional theory this can be understood as “solutions seeking problems to solve” rather than the other way around. In t
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
