A constantly growing intercontinental trade and modernization of transport infrastructure transformed the traditional patterns of carriage of goods globally. The majority of manufactured goods nowadays are transported in by sea in containers; however, transportation by land precedes and follows the sea carriage. These developments have created the preconditions for the development of multimodal tr

Popular Abstract in Swedish Den pågående ökningen av växthusgaser i atmosfären orsakar en ökning av den globala medeltemperaturen. En viktig påverkande faktor för koncentrationen koldioxid (CO2) i atmosfären är utbytet mellan atmosfären och biosfären; fotosyntesen tar upp CO2 och respirationen släpper ut CO2, vilket resulterar i ett nettoutbyte. För att öka vår förståelse av den spatiala och tempoThe ongoing increase in atmospheric greenhouse gas concentrations causes an increase in the global mean air temperature. One important moderator of the atmospheric carbon dioxide (CO2) concentration is the gas exchange between the atmosphere and the biosphere; photosynthesis extracts and respiration releases CO2, resulting in a net exchange. A variety of methods are used to improve our understandi

A set of new polymers that can be used as phase forming components in aqueous two-phase systems is presented. All polymers studied have thermoseparating properties i.e. form one separate polymer enriched phase and one aqueous solution when heated above the critical temperature. This property makes the polymers attractive alternatives to the polymers used in traditional aqueous two-phase systems su

The ongoing transition to renewable fuel sources has led to increased use of wood and other biomass fuels. The physiochemical characteristics of biomass combustion derived aerosols depends on appliances, fuel and operation procedures, and particles generated during incomplete combustion are linked to toxicity. Frequent indoor wood burning is related to severe health problems such as negative effec

BACKGROUND: It is important to clarify the biological function of the female sex hormones estrogen and progesterone in periodontal ligament cells, as these hormones may affect periodontal health. We have previously shown that human periodontal ligament cells express estrogen receptor beta (ERbeta) but not ERalpha, whereas human breast cancer cells (MCF7) express both ERalpha and ERbeta. Data on pr

The borehole thermal resistance – that is, the thermal resistance between the fluid in the U-tube and the borehole wall – is both a key performance characteristic of a closed-loop borehole ground heat exchanger and an important design parameter. Lower borehole thermal resistance leads to better system performance and/or lower total borehole length and possibly lower installation costs. Borehole th

Traumatic brain injury (TBI) survivors frequently suffer from life-long deficits in cognitive functions and a reduced quality of life. Axonal injury, observed in many severe TBI patients, results in accumulation of amyloid precursor protein (APP). Post-injury enzymatic cleavage of APP can generate amyloid-β (Aβ) peptides, a hallmark finding in Alzheimer's disease (AD). At autopsy, brains of AD and

A new, integrated, diagnosis tool in the field of industrial sustainability management named the ‘Initial Review for Sustainable Consumption and Production.’ was developed and tested. Most of the existing tools for an initial diagnosis and for identification of suitable interventions in this area have some of the following drawbacks: a. they are incomplete because they do not address all levels of

Popular Abstract in Swedish Senare års forskning har klart och entydigt pekat på njurens viktiga roll i utvecklingen av högt blodtryck. Det är mycket sannolikt att det föreligger flera av varandra oberoende mekanismer som förklarar uppkomsten av högt blodtryck, men det är möjligt att flera av dessa, på en organfysiologisk, cellfysiologisk eller genetisk nivå kan ha gemensamma patofysiologiska länkStudies were conducted to investigate the role of macula densa (MD)-derived nitric oxide (NO) in regulation of the glomerular filtration (GFR) through the tubuloglomerular feedback (TGF) mechanism. Immunocytochemical localization of the neuronal isoform of NO synthase (NOS) in the kidney showed that this isoform was exclusively located in MD cells. Whole kidney clearance measurements of GFR and mi

Popular AbstractAvhandlingen tar sin empiriska utgångspunkt i en analys av hur historiskt betingade värden hanteras i samtida planering samt natur- och kulturmiljövård. Syftet är att därigenom förtydliga förutsättningarna för en hållbar landskapsutveckling avseende landskapets historiska värden. Analysen tar sin teoretiska utgångspunkt i tidsgeografi och kritisk realism. Perspektiven har använts fThis thesis is based on an analysis of how historically motivated values are treated in contemporary planning- and conservation practices. The aim is to discuss the premises of a sustainable landscape development regarding historical landscapes and heritage. The analysis takes its theoretical point of departure in time-geography and critical realism. These perspectives have been used to develop a

Popular Abstract in Swedish I Sverige bestäms fastighetsgränsers sträckningar i första hand av gränsmärken på marken, därefter av förrättningskartor och mätuppgifter. Under senare år har efterfrågan på digital fastighetsinformation ökat kraftigt, inte minst beträffande lägesnoggranna gränsdata i den nationella registerkartan. Den utvecklade positioneringstekniken med GPS utgör idag en grundförutsäIn Sweden, the course of a property boundary is first and foremost determined by boundary marks on the ground, and only secondly by cadastral survey plans and measurements. In recent years, the demand for digital property information has increased substantially, not least in respect of accurate boundary data in the national cadastral map. Today, well-established techniques such as GPS positioning

Under den tidigmoderna och förindustriella perioden arbetade en stor del av den unga, ogifta allmogebefolkningen i Sverige som tjänstefolk, som drängar och pigor i andras hushåll. Där var de legalt underordnade husbonden och matmodern enligt särskilda tjänstehjonsstadgor och de hade begränsade möjligheter att söka annan försörjning, samtidigt som de ofta delade arbete och vardag med husbondfolket.The aim of this thesis is to analyze the power relations of labour and gender in the servant institution during the agrarian revolution in Sweden. The positions of servant, master and mistress are analyzed theoretically as a gendered, contracted position with both economic and moral dimensions attached to them. The analysis is applied together with a theory on bases of power, which are those areas

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, generates a large amount of waste heat. Some of this heat is partially recovered and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This work studies in detail four different solutions to utilize t

STUDY DESIGN: Retrospective study. OBJECTIVE: To describe surgical results in two and three dimensions and patient-reported outcomes of scoliosis treatment for Lenke type 1 idiopathic curves with an open anterior or posterior approach. SUMMARY OF BACKGROUND DATA: Different surgical techniques have been described to prevent curve progression and to restore spinal alignment in idiopathic scoliosis.

Context. The Gaia-ESO Survey (GES) is a large spectroscopic survey that provides a unique opportunity to study the distribution of spectroscopic multiple systems among different populations of the Galaxy. Aims. Our aim is to detect binarity/multiplicity for stars targeted by the GES from the analysis of the cross-correlation functions (CCFs) of the GES spectra with spectral templates. Methods. We
