Periodic INDO Calculations of Organic Adsorbates on a TiO2 Surface

A new parametrization for use in periodic semiempirical quantum-chemical INDO calculations is proposed. Parameter sets for C and N atoms are tested on a number of C- and N-containing molecules, giving reasonably good agreement with experimental data and/or ab initio results. The new parametrization is intended for studies of organic adsorbates on oxide surfaces using a periodic large unit cell (LU

Role of Neuropeptides and Neurotrophic Factors in Seizure Modulation

The presented thesis explores role of glial cell line derived neurotrophic factor family receptor a2 (GFRa2), as well as neuropeptide Y (NPY) and galanin and their receptors in modulation of seizure activity. We demonstrate that mice lacking the GFRa2 gene (GFRa2-/-) exhibit suppressed seizure generalization in traditional and rapid kindling models. We suggest that impaired basal excitatory transm

The use of market forces in social security: How insurance-like should social insurance be?

In this chapter two examples are presented were the Swedish legislator built market mecanisms into the unemployment insurance system and the pension system. The two market mecanisms were designed to make trade unions with high unemployment show restraint in collective wage bargaining and to make elderly people chose two postpone retirement. The aim of the legislation was to make the opposite choic

Praktikhandledning och professionell utveckling

Verksamhetsförlagda praktikperioder används som ett verktyg för att väva samman teoretisk och praktisk utbildning. Boken utforskar förutsättningar för en sådan kunskapsintegration i tre professionsutbildningar: psykolog, socionom och lärare. I en djupdykning i psykologutbildningens praktik beskriver blivande psykologer och handledare sitt lärande. En generell ram som kombinerar vetenskaplig forskn

Fisher information analysis and preconditioning in electrical impedance tomography

n this contribution, it is described how the Fisher information can be computed by using adjoint field techniques, and integrated with the gradient calculations used for optimization in electrical impedance tomography. In particular, the Fisher information can be used as a preconditioner to obtain improved convergence properties and a regularization for quasi-Newton optimization algorithms in elec

The Swedish Trade Union System in Transition: High but Falling Union Density

The chapter on Sweden in this book on trade union revitalisation in 34 countries analyzes the Swedish model of industrial relations and its current challenges, among them the falling union density. The recent development of industrial relations is characterized in terms of a new mix of decentralisation and centralisation and of self-regulation and state regulation. Contents of the Swedish chapte

Contact allergens in p-tert-butylphenol-formaldehyde resin

Popular Abstract in Swedish p-tert-Butylfenol-formaldehydharts (PTBP-F-R) är ett bindemedel som används i vissa limmer och målarfärger. Det har använts sedan 1950-talet och redan från denna tid finns rapporter om allergier. PTBP-F-R ingår i den internationella standardserien av kontaktallergen. Råvaror för framställning av hartset är p-tert-butylfenol och formaldehyd. Det färdiga hartset består avp-tert-Butylphenol-formaldehyde resin (PTBP-F-R) is used as a binder in many adhesive formulations and it consists of a complex mixture of substances, most of which are unknown. The resin has been reported to cause allergic contact dermatitis since the 1950s. The aim of the study was to investigate allergens in p-tert-butylphenol-formaldehyde resin (PTBP-F-R) and to isolate and identify sensitizer
