Protons or a-particles from a 3 MV tandem Pelletron are used to induce characteristic x-rays, which are detected by a Si(Li)-detector. To optimize the quality and speed of data taking we use an absorber with a hole, pile-up rejection and on-demand beam. Forty samples may be entered simultaneously into the vacuum, and their positioning is operated by pushbuttons. The system is prepared for minicomp

Den fackliga organisationsgradens utveckling i Sverige mellan oktober 2006 och oktober 2007 redovisas. Under denna 12-månadersperiod föll andelen fackligt anslutna löntagare med drygt fyra procentenheter. Om man avrundar till heltal rör det sig om ett medlemsras på hela fem procentenheter, från 77 till 72 procent fackanslutna. Det är den största fackliga nedgången under loppet av ett enda år i Sve

The elutability of adsorbed fibrinogen by cationic surfactants of different chain lengths (dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, cetyltrimethylammonium bromide), and an anionic surfactant (sodium dodecyl sulphate (SDS)) was studied using in situ ellipsometry. The concentrations of the surfactants were twice the CMC in water and for fibrinogen, 0.4 mg ml−1. The inve

The interaction between a cationic surfactant (dodecyltrimethylammonium bromide) and six model proteins adsorbed on to methylated silica and silica surfaces was investigated. The proteins were bovine serum albumin, cytochrome c, β-lactoglobulin, α-lactalbumin, lysozyme and ovalbumin. The adsorption of the proteins at pH 7 and their subsequent removal by surfactant were studied by in situ ellipsome

Background: The wide range of antibody specificity and affinity results from the differing shapes and chemical compositions of their binding sites. These shapes range from discrete grooves in antibodies elicited by linear oligomers of nucleotides and carbohydrates to shallow depressions or flat surfaces for accommodation of proteins: peptides and large organic compounds. Objectives: To determine t

Recombinant DNA technology has made it possible to produce specific Fab and scFv antibody (Ab) fragments in prokaryotic host cells. Using vectors designed for periplasmic expression of encoded Ab fragments, we have been studying how the sequence and genetic localization of the light chain (L-chain) variable region gene of a mouse Ab (CB-Nm.1) determined the level of Ab production. The variable reg

In recent years, two Swedish companies have been a focus of substantial media attention: TeliaSonera and Lundin Petroleum. The defensive strategies employed by these two businesses to deal with allegations of crime will be analysed on the basis of Stanley Cohen’s theoretical work on processes of denial and neutralisation techniques. This paper will focus on a particular form of denial, namely the

The association between HLA-DQ haplotypes and insulin-dependent diabetes mellitus (IDDM) was studied in 48 children from 44 families ascertained from the high incidence area around Umea, Sweden. Numerous hypotheses have been proposed to explain associations between HLA and IDDM, but comparisons of statistical models based on these hypotheses have not been attempted. The aim of the present study wa
