Slump, sammanträffanden och spår: Om en lärares inflytande

The paper describes the influence exercised by professor Kjell Granström in the teaching of psychology. Among pedagogical inventions inspired by Granström are to be found training in small group obesrvation in a laboratory format the use of group diaries, training in consultation. The importance of a close connection between research and teaching is discussed.

Biological reduction of hexavalent chromium - A field study

When ferrochromium is produced at Vargon Alloys AB (Vargon, Sweden), an offgas dust is generated as a byproduct. A leachate that contains hexavalent chromium (Cr6+) is formed when rainwater percolates through the dust deposit. In this study, Cr6+ in the leachate was reduced to trivalent chromium (Cr3+) by biological treatment in a biofilm process operated under anaerobic conditions. The reactor vo

High species richness of bees (Hymenoptera: Apoidea) at a farm in Stenbrohult, the birth place of Linnaeus

Solitary bees and bumblebees have declined substantially throughout western Europe during the last 100 years. Many species are important pollinators and are associated with particular plant species and habitats. In this study we report the highest number of bee species found at one locality in Sweden (Table 2). In total 87 species of wild bees (74 species of solitary bees and 13 species of bumble

A photoemission spectroscopy and X-ray absorption study of Bi(2)Sr(2)CaCu(2)O(8) single crystal with adsorbed Cs: On the origin of states affected by electron doping and evidence for spatially resolved electron doping

The influence of electron doping, via deposition of small amounts of Cs, on the electronic structure of has been studied by high-resolution photoelectron spectroscopy (PES) and x-ray absorption spectroscopy (XAS), utilizing synchrotron radiation. The changes in the electronic structure were monitored by PES of the valence band and of the O 1s, Bi 4f, Bi 5d, Ca 2p and Sr 3d core levels, and by XAS

Electrochemical and catalytic investigation of carbon paste modified with Toluidine Blue O covalently immobilised on silica gel

Toluidine Blue O (TBO) was covalently bound on silica gel and mixed with graphite powder and paraffin oil to produce modified carbon paste electrodes. The formal potential (E°′) of the covalently bound TBO was found to be −100 mV versus Ag|AgCl (KCl sat.) at pH 7.0 and the E°′ varied less than anticipated for a 2-electron–proton type mediator with pH. The bound TBO was found to act as an efficient

Cortical sensory and motor response in a patient whose hand has been replanted: One-year follow up with functional magnetic resonance imaging

Functional magnetic resonance imaging (fMRI) was used to study how a replanted hand regained its cortical territory parallel to recovery. The cortical response to sensory stimulation shifts from an ipsilateral to a bilateral pattern, and then to a predominantly contralateral activation. The cortical response to motor stimulation was normal from the first investigation.

A statistical analysis of NMR spectrometer noise.

Estimation of NMR spectral parameters, using e.g. maximum likelihood methods, is commonly based on the assumption of white complex Gaussian noise in the signal obtained by quadrature detection. Here we present a statistical analysis with the purpose of discussing and testing the validity of this fundamental assumption. Theoretical expressions are derived for the correlation structure of the noise

Structures of District Nurse : Patient Interaction

This dissertation is about social interaction between Swedish district nurses and patients when they meet to perform such routine things as to measure blood pressures or give injections. Conversation analytic methodology is used to explicate interactional structures and to understand how they come about; (i) how tests and treatments are achieved; (ii) how concerns are introduced; (iii) how test re

Vitamin D in normal and pathological parathyroid glands: New prospects for treating hyperparathyroidism (Review)

The secosteroid hormone active vitamin D [1,25(OH)(2)D-3] is a key player in the regulation of calcium homeostasis and bone mineralization. In addition, it has antiproliferative and prodifferentiating effects on various cells in vitro and in vivo. The action of 1,25(OH)(2)D-3 is mediated through the vitamin D receptor (VDR), which belongs to the superfamily of steroid/thyroid hormone nuclear recep

Low frequency spectroscopy of liquid water using THz-time domain spectroscopy.

In this paper we present an investigation of the dielectric response of H2O(1) and D2O(1) as a function of temperature from a supercooled state to near the boiling point. The data are obtained using THz-time domain spectroscopy, and covers the frequency range from 0 1-2 THz corresponding to 3 to 66 cm(-1). Before presenting the experimental results, we give a short introduction to some of the prop
