Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

Popular Abstract in Swedish De senaste åren har jag ägnat åt att undersöka en speciell typ av gelbildare: kappa-carrageenan. Kappa-carrageenan kan användas för att göra gelé men används också i annan mat t.ex. efterrätter och glass, för att ge konsistens. När man vill göra en gel av kappa-carrageenan blandar man ut lite pulver i vatten och kokar sedan upp det hela. När blandningen kyls av kommer dThe phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. In the presence of a binding anion (I-) the charge density of the helix increases and the aggregation of helices, and thereby the gelation,

Analysis of DIGE data using a linear mixed model allowing for protein-specific dye effects

Abstract in UndeterminedDifferential in-gel electrophoresis (DIGE) experiments allow three protein samples to be run per gel. The three samples are labeled with the spectrally resolvable fluorescent dyes, Cy2, Cy3, and Cy5, respectively. Here, we show that protein-specific dye effects exist, and we present a linear mixed model for analysis of DIGE data which takes dye effects into account. A Java

Spatial Separation of Closely-Spaced Users in Measured Massive Multi-User MIMO Channels

Fully-synchronous measurements of a massive multi-user multiple-input multiple-output (MU-MIMO) radio propagation channel are presented. We evaluate the ability of a massive MIMO system to spatially separate users located close to each other in line-of-sight (LOS) propagation conditions. The system consists of a base-station (BS) antenna array equipped with 64 dual-polarized antenna elements (128

Traffic Information Signs, Colour Scheme of Emergency Exit Portals and Acoustic Systems for Road Tunnel Emergency Evacuations

This work presents a literature review and a questionnaire study with 62 participants aimed at providing recommendations on the design of a set of evacuation systems for road tunnels: 1) Traffic Information Sign (TIS) - message and size of the sign (large or small), colour scheme, and use of pictograms and/or flashing lights, 2) Emergency exit portal layout - colour scheme, 3) Acoustic systems - v

Dealing with the combinatorial explosion of the morphological matrix in a "manual engineering design" context

The morphological matrix is an important element of the engineering design methodology and is present in many textbooks. This method originally aimed at generating an exhaustive set of solutions for a given problem, by decomposing it into subproblems, finding solutions to each subproblem, and combining them. One issue associated with the morphological matrix has been the necessity to deal with the

Om riskkommunikation: kartor, klyftor och mål

It is claimed that risk communication has the epistemic goal to inform and the pragmatic goal to change the recipients’ behaviour. The recipients should be considered as active agents with robust knowledge. Technical as well as psychological tools may be used to change the current knowledge state of the recipient and thereby her behaviour. These tools are mutually dependent and will change both th

Kunskapssamhällets marknad

Today, it is often said that we stand at the opening of a postindustrial “knowledge society,” where private enterprise has become increasingly dependent on research and innovation and where education has become a prerequisite for success on the labor market. This idea serves as a source of inspiration when governments, corporations and institutions elaborate policies and strategies for future deve
