Improving bio-literacy

Expanding bio-energy can help to fight climate change and improve energy security. The bio-energy industry in the EU is booming. Much of this success is based on the supportive EU directives and strategies that are stimulating national policies and innovation processes. However, the bio-energy industry is being confronted with a number of interconnected challenges that threaten its reputation, leg

Finns det en överreningsrisk?

Att avlägsna en luftförorening från en bostad kan ske på olika sätt, dels genom ventilationen dels genom att vissa föroreningar avlägsnas genom någon typ av filtrering av luften. Filtrering av luften används t.ex. vid olika typer av allergiska problem för att avlägsna icke önskvärda partiklar, t.ex. pollen. Filtrering har också föreslagits som en möjlig metod att minska stråldosen i samband med ra

I vant to be let alone - the construction of glamour

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

Ska kunskap vara fri?

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.

Determination of hyperfine structure and g j factors in the sequences of 2 D states in alkali atoms using a tunable dye laser

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 General Mode Matching Technique applied to Bandpass Radomes

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
