This thesis has been taking a starting point from a micro-level that focuses social structures, ethnic segregation and processes of development as phenomena from different levels of perspectives. The research focuses on housing-conditions in the urban room and take a starting-point in 1992 when an increased number of immigrant households, depending on social welfare, moved into Herrgården (Manor-H
In wastewater treatment plants (WWTPs) equipped with sludge digestion and dewatering systems, the reject water originating from these facilities contributes significantly to the nitrogen load of the activated sludge tanks, to which it is typically recycled. In this paper, the impact of reject water streams on the performance of a WWTP is assessed in a simulation study, using the Benchmark Simulati
In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase. However, when biofuels are burned or
The present study focuses on the preparation of poly(ethylene oxide) (PEO) nanocomposites based on the synthetic Laponite clay. The clay was added both in its pure form as well as organically modified with low molar mass poly(ethylene glycol) (PEG) components in order to enhance the compatibility between Laponite and PEO. Several PEG's with different end groups were used. Almost all of them were f
Popular Abstract in Swedish För att ge en god omvårdnad behövs kunskaper om ätproblem som helhet och om möjliga hinder för optimalt näringsintag hos äldre patienter, särskilt de med stroke. Sådana kunskaper behövs eftersom åldrandet i sig självt eller tillsammans med sjukdom, t.ex. stroke och dess följder, kan påverka förmågan att äta och därmed också näringsintaget med ökad risk för såväl undernäThe aim of this thesis was to describe eating difficulties and interventions to improve eating among elderly patients, especially those with stroke, to make comparisons between patients with dysphagia and those without (Papers I & II), those with and without assisted eating (Paper IV), and to analyse the relation between eating difficulties, nutritional status (Papers II-V), pressure ulcers (P
Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. The first industry investigated was phosphate processing in the manufacture of dicalcium phosphate (DCP), which is used
Time-resolved VUV laser spectroscopy has been performed to determine radiative lifetimes of several elements in atomic-beam systems. VUV radiation was generated by means of resonant four-wave mixing and stimulated anti-Stokes Raman shifting. Several methods to produce free atoms are presented and different techniques to determine radiative lifetimes are discussed. Doppler-free laser spectroscopy
Affinity two-phase partitioning based on an immunoaffinity sandwich approach for the rapid and selective purification of membranes is presented in this thesis. The method was developed by studying different parameters governing the affinity partitioning of model membranes. To this end, biotinylated liposomes were used. They specifically distributed to the bottom phase of a poly (ethylene glycol)/d
Molecular spiders are synthetic biomolecular walkers that use the asymmetry resulting from cleavage of their tracks to bias the direction of their stepping motion. Using Monte Carlo simulations that implement the Gillespie algorithm, we investigate the dependence of the biased motion of molecular spiders, along with binding time and processivity, on tunable experimental parameters, such as number
Popular Abstract in Swedish Mai Zetterling (1925-1994) var under fyrtiotalet skådespelare, både på Dramatens scen och i populära svenska filmer. Under sextiotalet regisserade hon fyra långfilmer. Dessa filmer ? Älskande par (1964), Nattlek (1966), Flickorna (1968) och Dr. Glas (1969) ? bemöttes emellertid allt mer negativt av de svenska filmkritikerna. Under återstoden av sitt liv regisserade ZettMai Zetterling (1925-1994) was a popular actress in the 1940s. In the 1960s, she directed four feature films. The films ? Loving Couples (1964), Night Games (1966), The Girls (1968) and Dr. Glas (1969) ? were met with increasing hostility by Swedish critics, however, and after the 1960s, Mai Zetterling only directed two more feature films in her life, the British Scrubbers (1982) and the Swedish A
The aim of the present doctoral thesis is to study and conceptualize juridification as a phenomenon. This aim comprises analyzing the theories through which juridification as an empirical development is interpreted. In this thesis juridification signifies displacements towards legal discourse. Juridification comes about when an issue that was previously dealt with within a cultural, ethical, polit
ObjectiveTo determine whether an experienced ultrasound examiner, using good ultrasound equipment with high multifrequency probes, can discriminate between a high grade or low grade dysplastic adenoma (pT0) and very early invasive rectal cancers (pT1). Subjects and methodsSixty consecutive patients with clinically possibly pT0 or pT1 rectal tumours referred for transanal local excision underwent
The influence of external nitrogen (N) on carbon (C) allocation and processes related to phosphorus (P) metabolism were studied in monoxenic arbuscular mycorrhiza (AM) cultures of Daucus carota. Fungal hyphae of Glomus intraradices proliferated from colonized roots growing on solid medium into C-free liquid minimal medium with two different N and P levels. Furthermore, we exposed the colonized roo
BackgroundSocial function is a key aspect of health‐related quality of life after solid organ transplantation (SOT). The focus of this study was to report how solid organ‐transplanted patients change their social function after transplantation.AimTo investigate the main concerns associated with social function after SOT and how solid organ transplant recipients (SOTRs) deal with these concerns.Met
Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA (Swedish summary) Ultraljud används sedan 1970-talet rutinmässigt under graviditet. Undersökningen görs vanligen vid 17-18 graviditetsveckor och syftet med undersökningen är att datera graviditeten dvs bestämma tiden för beräknad förlossning. Man upptäcker också eventuella tvillingar vid denna undersökning. Redan tidigt visade det sig att visWe studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. We studied the effect of prenatal diagnosis on the rate of spina bifida in southern Sweden compared with the rest of the country and could show tha
Vitellogenin (VTG) is a well known protein biomarker for exposure to environmental estrogens and possible endocrine disruption in fish. VTG is very dominant in plasma after the onset of vitellogenesis and the protein is heavily phosphorylated. This enables indirect quantification through measurement of alkali-labile protein bound phosphate (ALP) as an alternative to the more expensive enzyme linke
