This thesis summarises experimental results on the molecular spectroscopy of gas phase molecules excited by synchrotron radiation in the VUV and soft X-ray regions. We have used three different detection techniques, photon in- duced fluorescence spectroscopy, photoionisation mass spectroscopy and near edge X-ray absorption fine structure spectroscopy to study molecular deu- terium, hydrogen sulp
Developments in body theory have had a strong impact on archaeology in recent years, but the concept of the body has tended to remain abstract. The term “body” is often used as a synonym for self or person, and the remains of bodies and body parts have often been approached theoretically as signs or symbols. While this has emphasized the importance of the body as a cultural construct and a social
Sp1/Kruppel-like factor (KLF) family of transcription factors regulates diverse biological processes including cell growth, differentiation, and development through modulation of gene expression. This family of factors regulates transcription positively and negatively by binding to the GC and GT/CACCC boxes in the promoter through their highly conserved three zinc finger domains. Although the mole
Biochar addition to soils has been proposed as a means to increase soil fertility and carbon sequestration. However, its effect on soil nitrogen (N) cycling and N availability is poorly understood. To gain better insight into the temporal variability of the impact of biochar on gross soil N dynamics, two 15N tracing experiments, in combination with numerical data analysis, were conducted with soil
The main aim of the present thesis is to demonstrate the efficient quantum memories for light employing coherent processes in rare-earth-ion-doped crystals. Rare-earth (RE) ions between lanthanum, with atomic number 57, and lutetium, with atomic number 71, have a partly filled 4f shell, which is spatially inside the full shells 5s, 5p, and 6s. Therefore, 4f-4f transitions are shielded from environ
Instruments related to work are commonly illuminated from an ill-health perspective. The need for a concise and useable instrument in workplace health promotion governed the aim of this paper which is to present the development process and quality assessment of the Work Experience Measurement Scale (WEMS). A survey, using a questionnaire based on established theories regarding work and health, and
Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers, and thereby also the load distribution, depend on the two connecting spans, it has been necessary to inclu
Popular Abstract in Swedish Det mesta i min avhandling handlar om utveckling av uppreningsprocesser i läkemedelsindurstin. Den stora kostnaden för läkemedelsföretagen ligger oftast inte i att producera ett läkemedel, utan att ta fram en produkt. Det är också långt ifrån alla kandidater till läkemedel som till slut blir en produkt. Detta kan till exempel bero på att kandidaten inte var tillräckligtIn my thesis, I have modeled adsorption chromatography and simulated, calibrated, and analyzed models of adsorption chromatography. While my main focus has been modeling and calibration of the models by estimating the parameters, the models used have been partly new. The simulations are differentiated from the modeling in that the modeling describes the partial differential algebraic equation, whi
When the ethnographer Wilson Wallis did his first fieldwork among the Canadian Mi’kmaq Indians 1911, one recurrent character in their oral tradition was the traditional culture hero Kluskap. When Wallis returned to Nova Scotia in 1953 he found that not many Mi’kmaq in the thirties had heard about Kluskap, and if they had, it was through books or the television series “The Adventures of Glooscap”.
The revised version of the Swedish Aliens Act contains a specific category providing protection for persons who fear persecution on account of their sex. Benefits afforded under this category, however, fall short of those under the 1951 Convention relating to the Status of Refugees or article 3 of the European Convention for the Protection of Human Rights and Fundamental Freedoms. In order to eval
Savanner är ett landskap med både träd och gräs som skapar en miljö som varken är skog eller gräsmark. Savanner tar upp cirka en sjättedel av världens totala landyta och de har på grund av detta en stor betydelse för den globala kolbalansen. De flesta savanner har två distinkta säsonger, en regnperiod då vegetationen grönskar samt en period med torka utan nederbörd. Detta gör att förändringar i deSavannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. Most savannahs are characterized with two distinct seasons, one dry season and one wet season where a maj
Objective:: The loss of a parent to cancer is considered one of the most traumatic events a teenager can experience. Studies have shown that teenagers, from the time of diagnosis, are already extremely worried about the consequences of a parent's cancer but tend to be left to manage these concerns on their own. The present study aimed to explore young adults' advice to healthcare professionals on
The energy efficiency and thermal performance of highly glazed office buildings are often questioned. However, nowadays glazed buildings are increasingly being built around the world, mainly due to an architectural trend, followed by the preference of companies to a distinctive image that a glazed office building can provide. Due to insufficient knowledge concerning the performance as to energy us
Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt
Drought is arguably the most important regulator of inter-annual variation in net ecosystem CO2 exchange (NEE) in peatlands. This study investigates effects of drought periods on NEE and its components, gross primary production (GPP) and ecosystem respiration (R-eco), on the basis of eddy covariance measurements of land-atmosphere exchange of CO2 in 2006-2009 in a south Swedish nutrient-poor peatl
ABSTRACT Polymorphic crypsis has been observed in several taxa, but has, until now, lacked a firm theoretical understanding. How does a single morph, well camouflaged in one type of habitat, evolve crypsis in another, not isolated, habitat? We here analyze a model of one prey species living in two different habitats connected by passive dispersal. We find that the rate of dispersal, the trade-off
Theoretical ecologists have long sought to understand how the persistence of populations depends on the interactions between exogenous (biotic and abiotic) and endogenous (e.g., demographic and genetic) drivers of population dynamics. Recent work focuses on the autocorrelation structure of environmental perturbations and its effects on the persistence of populations. Accurate estimation of extinct
The combination of polyethylenimine (PEI), as a plasmid DNA pre-condensing agent, and cationic lipids has been reported to result in a synergistic effect on transfection. Recently, we have explored this effect by associating low-molecular weight PEIs with transferrin-associated lipoplexes using different cationic liposome formulations. The resulting lipopolyplexes that have shown to be the most ef
When Swedish wastewater treatment plants were rebuilt to include enhanced nitrogen removal, anaerobic ammonium oxidation (anammox) was far from being a mature technology. During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is decreasing, but lab- and pilot-scale studies on real municipal wastewater are yet lackin
BackgroundFood habits, nutrient needs and intakes differ between males and females, although few nutritional studies on patients with coeliac disease (CD) have reported results stratified by gender. ObjectivesTo compare energy and nutrient intakes among 13-year olds diagnosed with CD in early childhood with those of a non-coeliac (NC) age- and gender-matched control group, and also with estimated
