It is not too far fetched to claim that celebrity is a phenomenon that is difficult to define. It is hard to maintain rigid hierarchies between the components that make up celebrity. One of them can be described as glamour. In the paper I examine ways to understand glamour as an intrinsic part of the symbolic construction of celebrity. It has been used as a inherent quality in the person (Gould, 2
I en tid när allt omkring oss tycks vara tätt insyltat i informationsflöden, när vi talar om lärande för livet och värdet av såväl social som digital delaktighet torde det vara rimligt att även vi alla tar plats på den banan. Bortom de träiga och gammalmodiga inlåsningarna.
We have extended recently reported hyperfine structure studies of 2D states in alkali atoms to several new states. The 2D states were populated in a two-step excitation scheme, involving a conventional RF lamp and a cw tunable dye laser. Using level crossing and optical double resonance techniques we have determined the hyperfine structure of the 8 2D3/2,5/a states in 8TRb and the 11, 12, 13, 14 a

A new method based on the mode matching technique and the finite element method (FEM) is presented. The method can handle a general thick frequency selective structure (FSS), that consists of an arbitraryn umber of aperture layers and dielectric layers. An aperture layer consists of a conducting plate with a periodic arrayof apertures. The order and the thickness of the layers can be arbitrary. The
Fuel cells are electrochemical devices that directly transform chemical energy into electricity, which are promising for future energy systems, because they are energy efficient. The cell performance depends strongly on the material characteristics, the operating conditions and the chemical reactions that occur at active sites. The steam reforming and electrochemical reaction rates depend on tempe
