Powerformer™: A giant Step in Power Plant Engineering

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

Correlation between clinical characteristics and cerebrospinal fluid neuropeptide Y levels in dementia of the Alzheimer type and frontotemporal dementia

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)

A Master of Ergonomics Programme in Sweden

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.

n exact ab initio theory of quantum transport using TDDFT and nonequilibrium Green’s functions

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

Managerialism and the care of older people: The Swedish example

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

Effect of freestream turbulence on heat transfer and fluid flow in a transonic turbine stage

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
