Popular Abstract in Swedish Avhandlingsarbetets främsta syfte har varit att analysera vilka drivkrafter som ligger bakom beslutet att återvandra, samt att kartlägga återvandringen från Sverige 1968-1996 avseende sammansättning och utvecklingsmönster. Analysen har bedrivits ur ett arbetsmarknadsekonomiskt perspektiv, med fokus på den långsiktiga utvecklingen av tillgång och efterfrågan på arbetskraThis book deals with return migration from Sweden in the period 1968-1996 to Chile, Germany, Greece, Iran, Poland, Turkey, United States and Yugoslavia, against the background of economic and political developments in Sweden and in the different source countries. An important question in the study regards whether return migrants deviate from other immigrants in terms of human capital characteristi

Recent experiments on mid-gap laser-triggered electrical breakdown in liquid dielectrics have been scrutinised. The sequence of events that leads to the disruptive discharge is described and accompanied by electric field calculations.

Adaptations and, counteradaptations are common in coevolving predatorprey systems, but little is known of the role of maternal transfer of adaptive traits in mediating species interactions. Here, we focused on tolerance against cyanobacterial toxins and asked whether this tolerance was an induced defense developed during Daphnia's lifetime, whether it was a trait that is constantly expressed, and

The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. The main requirement of these tanks, is to provide an optimal environment for the microorganisms found inside, with homogeneous mixing of air. The flow in a aerate

This paper investigates the acquisition of relative clauses in the spontaneous production data of a bilingual Icelandic-English-speaking child.

Previous work has indicated a crucial role for the extracellular cysteine proteinase of Streptococcus pyogenes in the pathogenicity and virulence of this important human pathogen. Here we find that the purified streptococcal cysteine proteinase releases biologically active kinins from their purified precursor protein, H-kininogen, in vitro, and from kininogens present in the human plasma, ex vivo.

Emerging lines of evidence indicate that the cutaneous human papillomavirus (HPV) types that belong to the genus Betapapillomavirus (beta HPV) are involved in the development of nonmelanoma skin cancer. Unlike the situation for mucosal HPV types, highly sensitive and reliable methods to identify characterized cutaneous HPV types in a single assay are limited. Here, we describe a novel one-shot met

A fully integrated 0.6 V VCO for the GPS L1 band is realized in a 90 nm RF-CMOS process. The purpose of the design is to demonstrate how suitable deep submicron CMOS transistors are for ultra low voltage, low power oscillator design. The VCO operates at 6.3 GHz and a divide-by-four circuit buffer provide the wanted 1575.42 MHz signal. Measured phase noise is for a 0.6 V supply voltage and bias cur

The project developed by three institutions in Denmark and Sweden –Malmoe School of Education, City Archives of Malmoe and the Cultural History Workshop in Denmark– uses the methods of oral history as an instrument in the production of historical awareness. It tries to elaborate multiple histories at several levels –nation, regional, local; ethnicized and gendered, social and political history– th

This paper presents application of sustainable tourism practices by leading tour operators in international ecotourism supply chains. Observations of actions implemented by the inbound and outbound operators creating the ecotourism experience are drawn from two case studies – one of trips to Peru and the other of trips to Nepal-Bhutan - both available on the Swedish market. The cases explore how s

The effect of various deposition techniques, electrode materials and posttreatment with tetrabutylammonium and tetrabutylphosphonium salts on the electrochemical behavior and stability of various Prussian blue (PB) modified electrodes, namely PB modified glassy carbon electrodes, silicate-film supported PB modified glassy carbon electrodes, PB-doped silicate glassy carbon electrodes, PB modified c

Intratracheal instillation of Sephadex beads induced a long-lasting inflammation in the rat lung as seen by an increase in lung weights. Repeated instillation enhanced this reaction and increased lung endothelin-1 content 3.5 times. Budesonide given s.c. abolished these effects and even reduced basal endothelin-1 content by 72%. The tissue content of the sensory neuropeptide neurokinin A were unaf

Submerged sea grasses and stoneworts growing in the immediate nearshore of the Baltic Sea are sensitive indicators of sea level. The alternating changes in concentrations of sea grass and stonewort macrofossils, obtained from an ancient lagoon of the Baltic Sea, are ascribed to middle Holocene sea-level fluctuations along the southeastern Swedish coast. Abundances of stonewort and sea grass macrof

Data from Z decays in DELPHI have been searched for <(B-d(o))over bar> --> D*+ l(-) (ν) over bar (l) with the D*+ decaying to D(0)pi(+) and D-0 --> K(-)pi(+), K(-)pi(+)pi(+)pi(-) or K- pi(+)(pi(0)). These events are used to measure the CKM matrix element V-cb and the form factor slope, rho(A1)(2): F-D*(1) V-cb = 0.0392 +/- 0.0018 +/- 0.0023; rho(A1)(2) = 1.32 +/- 0.15 +/- 0.33 corresponding to a b

PURPOSE: To clinically characterize a Swedish family with autosomal dominant retinitis pigmentosa due to a mutation, Arg-172-Trp, in the peripherin/RDS gene. METHODS: Full clinical evaluation including kinetic visual field testing, measurement of dark-adaptation threshold, and full-field electroretinography in seven patients with autosomal dominant retinitis pigmentosa and three healthy family mem
