Popular Abstract in Swedish Kvinnor känner till att det är riskabelt att röka när de blir gravida. Trots detta så slutar bara omkring hälften i Sverige och var tredje kvinna i många andra länder att röka när de blir gravida. Syftet i den här avhandlingen har varit att studera varför det är så svårt för gravida kvinnor att sluta röka. Problemområdet har studerats med olika utgångspunkter; gravida kThe aim of this thesis has been to increase understanding on the process of smoking cessation during pregnancy from the perspective of learning. The smoking pattern before and after pregnancy related to health, Sense of Coherence (SOC) and social issues was studied among all pregnant women in south-east Skåne during the period March 1994 to August 1995. They were asked to fill in a questionnaire d

Popular Abstract in Swedish Antikroppar är viktiga beståndsdelar av det naturliga immunförsvaret som skyddar oss mot smittämnen, såsom bakterier och virus. Utvecklingen av olika genetiska och biokemiska teknologier har dessutom möjliggjort användningen av antikroppar för en mängd ändmål, bl a för diagnostik och behandling av infektionssjukdomar och cancer. I denna avhandling, som bygger på fem vetAntibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer. Despite tremendous advances in all fields

The Öresund Region is a transnational region encompassing areas of southern Sweden (Skåne) and southeast Denmark (Sjælland and Hovedstaden). The Energi Öresund project seeks to offer strategic and cooperative energy planning for the region as a whole in order to meet the energy goals of Sweden, Denmark, and its constituent local municipalities. The project is funded by EU INTERREG IV, a European U

Popular Abstract in Swedish Eftersom gamla träd har blivit mycket ovanligare de senaste 200 åren, både i skogslandskapet och på ängs- och hagmarker, har djur som lever i gamla träd blivit mycket sällsyntare och många arter är utrotningshotade. I gamla ekar bildas ofta mulm i stammarnas håligheter. Mulmen består av murket trämjöl och i den lever en rik och specialiserad fauna som framför allt utgörMany species associated with old trees are threatened, as this habitat has decreased severely in Europe during the last 200 years. In old oaks, hollows with wood mould often form in the trunks and these harbour a specialized fauna mainly consisting of beetles, flies and pseudoscorpions. This thesis contains the first quantitative examination of the habitat requirements and population ecology of sp

Two-photon-induced Degenerate Four-Wave Mixing, DFWM, was applied for the first time to the detection of CO, and NH3 molecules. Measurements were performed in a cell, and in atmospheric-pressure flames. In the cell measurements, the signal dependence on the pressure and on the laser beam intensity was studied. The possibility of simultaneous detection of NH3 and OH was investigated. Carbon monoxid

The most commonly used method to measure telomerase activity in cells is the telomerase reverse amplification protocol (TRAP) assay, where the protein extracts derived from homogenized cells are analysed. In this thesis we focused on developing a method where telomerase activity co

Demands for efficient, economical and fast separation and purification methods for various target molecules have led to the development of new techniques and materials for bioseparation processes. Separation can be carried out in both batch and chromatographic modes. Running the separation step in a conventional chromatographic column is more efficient than batch mode, but there are some limitatio

The aim of the work presented in this thesis was to investigate nature of adsorption of amphiphiles to the solid–liquid interface. The surface aggregate structures of the zwitterionic surfactant dodecyldimethylammoniopropanesulfonate, (DDAPS) and a series of nonionic polyoxyethlylene glycol alkyl ethers (C10E5, C12E5, C12E8, C10E6, C14E6 and C16E6) have been determined by Atomic Force Microscopy o

Popular Abstract in Swedish För att öka förståelsen för hur ljud sprider sig och strålar från byggnadskonstruktioner utförda i lättbyggnadsteknik så behövs teoretiska beräkningsmodeller. Sådana modeller presenteras i avhandlingen. Med lättbyggnadsteknik avses konstruktioner som inte är massiva, exempelvis väggar och bjälklag bestående av trä- eller stålreglar/bjälkar. Stegljudet, det vill säga det

Popular Abstract in Swedish Blodet innehåller några av de mest grundläggande komponenterna för mänskligt liv. Med hjälp av hjärtats pumpkraft transporterar röda blodkroppar ut syre från lungorna till de mest avlägsna delarna av kroppen via gradvis tunnare blodkärl. Livshotande blödningar stoppas via blodplättarnas koagulerande förmåga och läkande egenskaper, medan de vita blodkropparna bekämpar inHematopoietic stem cells (HSCs) are defined by their capacity to self-renew and differentiate into all hematopoietic cell lineages. Postnatally, HSCs reside predominantly in the bone marrow and are relatively rare, but important cells because of their therapeutic potential in bone marrow transplantation protocols and in their involvement in the origin of certain leukemias. To study how various gen

The Swedish model of industrial relations is distinguished by a high degree of self-regulation with roots around the turn of the century 1900. Under the threat of state regulation, the labour market parties in the 1930s, and again in the late 1990s, found they had a common interest in self-regulation. The 1938 Saltsjöbaden Agreement between the blue-collar confederation LO and the employer confede

Comparative empirical studies of the link between economic growth, carbon emissions and ecological footprints (e.g. Fritz and Koch 2016) suggest that current Western production and consumption patterns and welfare standards are incompatible with environmental limits and IPCC climate targets. In the absence of evidence for absolute decoupling of economic growth, material resource input and carbon e

World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. Extracting the chemical energy of fuels is done through combustion of the

The glymphatic system is a brain-wide solute clearance system that has developed in the brain to clear metabolic waste during sleep. This clearance is mediated by advective fluxes of cerebrospinal fluid (CSF) along perivascular spaces (PVS) and through the brain. The movement of CSF from the PVS and through the brain is dependent on the polarised expression of aquaporin-4 (AQP4) at astrocyte endfe

The Social and Solidarity Economy (SSE) have proved to combat inequalities, neoliberal policies, and ultimately, counteract the hegemonic economic rationale imposed by the market (Gaiger 2007). In particular, co-operatives are engaged in some market activity, although the economic principle does not prevail over the social objectives of the organisation. Indeed, this is the core of the social inno

NOx pollution from diesel engines has been stated as causing over 10 000 pre-mature deaths annually and predictions are showing that this level will increase [1]. In order to decrease this growing global problem, exhaust after-treatment systems for diesel engines have to be improved, this is especially so for vehicles carrying freight as their use of diesel engines is expected to carry on into the

Importance: Neonatal hyperbilirubinemia can cause lifelong neurodevelopmental impairment (kernicterus) even in high-resource settings. A better understanding of the incidence and processes leading to kernicterus may help in the design of preventive measures.Objectives: To determine incidence rates of hazardous hyperbilirubinemia and kernicterus among near-term to term newborns and to evaluate heal

Context. Young massive stars inject energy and momentum into the surrounding gas, creating a multi-phase interstellar medium (ISM) and regulating further star formation. The main challenge of studying stellar feedback proves to be the variety of scales spanned by this phenomenon, ranging from the immediate surrounding of the stars (Ha II regions, 10s pc scales) to galactic-wide kiloparsec scales.
