Porphyrins have become an interesting class of molecules in studies of molecular electronics. They are, however, sensitive to handling procedures and may give different results in electronic or optical properties depending on the method used for coupling or adsorption. We present electronic measurements of a heme porphyrin mounted in a biomolecular structure-an enzyme-and show that a direct electr

Why do viewers perceive and interpret visuals differently despite common perceptual and cognitive mechanisms? The article addresses a number of challenges in visual communication and underlines the need for empirical analyses from a recipient perspective. Perception and interpretation of visuals is seen as an interactive meeting between the recipient, the multimodal message and the situational con

In this paper, a new method for the design of approximately linear phase IIR filters is proposed. This method is based on first designing an asymmetrical FIR filter which is approximately linear phase and then deriving a low order approximately linear phase IIR filter by model reduction techniques.

The representations of Adolf Eichmann includes those from the trial against him in Jerusalem, but also a large amount from films and television series. How do these relate to Hannah Arendts famous quotation of Eichmann as the incarnation of the banality of evil?

Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. Most natural organic waste can be used in anaerobic digestion. In developing count

I tre fallrapporter från forskningsprojektet Framgångsrikt skolledarskap i olika skolkulturer presenteras resultat från omfattande empiriska undersökningar vid tre skolor. I rapporterna beskrivs och problematiseras skolornas respektive kultur: den aktuella gymnasieskolans kunskapskultur, där bildning kommit att bli ett kännetecken; den utvalda f-9-skolans karriärkultur, utsatt för ett kraftfullt f

An important part of introduction of the construction productive directive (CPD) is the introduction of the so-called Euroclasses for building products. The Euroclasses define the different fire classes within the European harmonised system. The major fire test method in this system for wall and ceiling linings, the so-called SBI test (EN 13823), is, however, an intermediate fire test and requires

In this work, we present a built-in filter method to enhance the isolation level between closely packed MIMO antennas. The built-in filter is composed of several slits etched on the ground of the antenna structure. The number and length of slits depend on both the resonance frequency and the structure of the MIMO antenna system. To illustrate its usefulness, two designs of compact planar four-port
