In 1949, Swedish actress Ingrid Bergman caused a well known scandal in Hollywood by leaving her Swedish husband Petter Lindström and their daughter for Italian film director Roberto Rossellini. The effects of this scandal in America have been thoroughly described in works like Bergman’s autobiography (Bergman, 1980), Donald Spoto’s recent biography on Bergman (Spoto, 1997) and in specialized schol

In this study, topological structures of a separation bubble in a ribbed channel are identified and analyzed. Particle image velocimetry (PIV) and POD (proper orthogonal decomposition) filter are used to give the velocity vector field. The ribs obstruct the channel by 20% of its height and are arranged 9 rib heights apart. The Reynolds number is 22000 based on the bulk-mean velocity and channel he

Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the differential mobility particle sizer (DMPS). Programs have been developed to invert DMPS measurement

An impulse radio transmitter at 60 GHz with pulse duration time down to 100 ps is reported. OOK modulation is presented and the results show promise for other modulation schemes. The transmitter consists of a gated tunnel diode in parallel with a coplanar waveguide, which is a design that provides direct conversion from the baseband pulse train to radio frequency wavelets with a center frequency o

A simple and direct method based on hollow fibresupported liquid membrane (HFSLM) extraction and liquid chromatography equipped with a UV detector was developed for analysis and quantification of parabens in cosmetic products. The parabens analysed included methyl, ethyl, propyl, isobutyl and butyl paraben. The HFSLM extraction was carried out by employing di-n-hexyl ether as organic liquid that w

Popular Abstract in Swedish Proteinvecknings- och proteindesign-problemen studeras med hjälp av modeller med låg upplösning och endast två typer av aminosyror, hydrofoba och hydrofila. Förutom hydrofoba krafter innehåller modellerna sekvensoberoende lokal växelverkan som visar sig ha stor påverkan på termodynamiken hos dessa modeller. Modellerna studeras med hjälp av dynamisk-parameter Monte CarloThe protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. The models are studied using the dynamical-parameter Monte Carlo method.

This study is done within the framework of a project aimed at developing a wearable device (a bracelet) intended to support sensory motor rehabilitation of children with visual impairments. We present an exploratory study of aesthetic/hedonistic preferences for sounds and touch experiences among visually impaired children. The work is done in a participatory setting, and we have used mixed methods

Design has received increased attention not least of all in the business press and journals. The concept of design thinking – how to approach problems in a designerly way – is sometimes attributed as being the savior of business, making companies creative and innovative. This kind of exaggeration does more harm than good to industrial design consultancies (IDCs) and their client firms (CFs). And y

This paper treats robustness constraints and performancecriteria for design of PID controllers. It is shown that robustnessconstraints are essential, and that controller design basedon maximization of performance criteria without robustnessconstraints give poor controllers. It is also shown thatthe robustness constraints have a significant influence on theperformance, and that the performance ofte

Maktförhållandena på den svenska arbetsmarknaden har växlat mellan perioder av facklig offensiv och perioder då arbetsgivarna drivit utvecklingen i sin riktning. Utmärkande för Sverige är att parterna snarare än staten står för arbetslivets reglering. Det har inte hindrat att staten under vissa perioder uppträtt mer aktivt än under andra. I kapitlet anläggs ett 100-årsperspektiv på de svenska arbe

The aim of this study was to investigate use and need for assistive devices (AD) in a cross-national European sample. Data from the ENABLE-AGE research project were utilised involving very old persons in Sweden, Germany, Latvia, Hungary and the United Kingdom. Of the total sample 65% reported that they had and used one or more AD, and 14% reported unfilled need for AD. The most commonly used AD we
