Falling birth rates within the European Union have given rise to a number of studies, trying to analyse and interpret why women (and men) choose not to have (many) children. One attempt in this direction is made by an ongoing EU-project, involving eight countries, including Sweden. Qualitative interviews focusing on couples' decisions to have- or not have - children have been carried out in each c
The evolution of dispersal was investigated in an adaptive individual-based metapopulation model, which allowed for demographic and environmental stochasticity. The individual dispersal behaviour was determined by a one-locus genotype subjected to simple inheritance and mutation. Dispersal behaviour could therefore evolve through the genotype–phenotype mapping and the selection regimes stemming fr
Dextran-conjugated EGF (EGF-dextran) has a potential use for targeted radionuclide therapy of tumors that overexpress the epidermal growth factor receptor (EGFR). There are plans to treat both bladder carcinomas and malignant gliomas with local injections of radiolabeled EGF-dextran since these tumors often express high levels of EGFR. In this report we show that EGF and EGF-dextran differentially
Popular Abstract in Swedish Sjukgymnaster har behandlat patienter i samband med kirurgisk behandling sedan början på 1900-talet och den dominerande uppgiften har varit att förebygga lungkomplikationer och blodproppar samt att bedöma behovet av vidare rehabilitering efter utskrivning. Den medicinska utvecklingen går emellertid snabbt framåt och sjukgymnasten har en utmanande uppgift i att utveckla The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible. It was shown that an airflow of 42.5
Purpose. In previous studies of subretinal transplantation in rabbits, the host photoreceptor layer seemed to prevent the bridging of neuronal fibers between the graft and the host retina. The current study was undertaken to determine whether the same phenomenon occurs in transplants to the subretinal space of the vascularized retina of rats. Bridging of fibers was examined in transplants to anima
As the ‘third wave’ progressed it has been argued that democratisation should be analysed in terms of partial regimes rather than with multidimensional concepts of democracy. This article analyses the democratic qualities of one such partial regime, albeit arguably the core dimension of representative democracy: multiparty elections. The analysis focuses on the three basic democratic values of ele
This article seeks to describe and understand relational interaction processes in project networks, and suggests that there is a connection between the characteristics of a project network and the type of interactions within it. We suggest that time, legitimacy and power structure determine the type of interaction processes that occur. Four case studies of service-producing project networks show t
In the 1990s, HIV/AIDS became a major threat to health, economic stability and human development in countries in eastern Europe and central Asia. Social, political and economic transition exacerbated the structural conditions that allowed HIV/AIDS to flourish as dramatic changes led to increasing drug injection, economic decline and failing health and healthcare systems. There is a need to address
Study of anti-Thatcherist tendencies in British cinema of the 1980s.
The influence of different types of surfactants on ultrafiltration membranes has been investigated. A basic approach to membrane-surfactant interactions is also presented. A nonionic (Triton X-100), two anionic (potassium oleate and sodium dodecylbenzenesulphonate) and a cationic (hexadecyltrimethylammonium bromide) surfactant were investigated. The effects on commercial membranes of polysulphone,
Alzheimer´s Disease (AD) is a progressive neurodegenerative dementia characterized by the extracellular accumulation of the beta-amyloid (Ab) peptide into plaques and intracellular phosphorylation and accumulation of tau protein into neurofibrillary tangles (NFT). Inflammation due to astrocytic and microglial activation is one of the ongoing processes in the disease giving rise to cytokine product
A brief introduction to convolutional coding is given. The active distances are reviewed and shown to be an important tool for analyzing the error correcting capability of maximum-likelihood (ML) decoding of convolutional codes when communicating over a binary symmetric channel (BSC). Due to memory and delay constraints in practical coding schemes, convolutional codes often are either terminated o
Combined quantum chemical and molecular mechanics geometry optimisations have been performed on myoglobin without or with O(2) or CO bound to the haem group. The results show that the distal histidine residue is protonated on the N(varepsilon2) atom and forms a hydrogen bond to the haem ligand both in the O(2) and the CO complexes. We have also re-refined the crystal structure of CO-myoglobin by a
We study the concept of self-similarity with respect to stochastic time change. The negative binomial process (NBP) is an example of a family of random time transformations with respect to which stochastic self-similarity holds for certain stochastic processes. These processes include gamma process, geometric stable processes, Laplace motion, and fractional Laplace motion. We derive invariance pro
The currant shoot borer, Lampronia capitella (Lep., Prodoxidae), is an important pest of currants, Ribes spp., in northern Europe. Oviposition was studied in cage experiments and the flight period was monitored in field studies using pheromone-baited traps. Blackcurrant, Ribes nigrum, was the host species in both studies. The total egg supply of females was on average 107 eggs and oviposition star
Sweden's decision to choose neutrality as its security policy orientation in the first half of the nineteenth century is explained with the help of image theory. It is argued that a theory focusing on the images of policy-makers regarding self, others and situation provides a better explanation of these strategic decisions than traditional balance-of-power theories. The important role of enemy-ima
