There is an extensive expansion of fiber infrastructure for high-speed broadband networks in Sweden, and Landskrona municipality is one of the leading examples. Owing to the superior capabilities of a fiber based network, a number of digital welfare services can be provided directly to residents and companies of the municipality. Social care is an example of a welfare service that can utilize the
The protection of farmland in property formation relies heavily on one part of the Swedish property formation law, 3 kap. 6 § fastighetsbildningslagen. The overall purpose of this specific law is to secure the national food supply of Sweden but in reality it is only effective regarding the very large agricultural properties which leaves a lot of the actual farmland without protection. As a result
Popular Abstract in Swedish Isocyanater är en grupp kemiska ämnen som används vid tillverkning av polyuretanplast (PUR). PUR ingår bland annat i färg, lim, lack och skumgummi, vilka förekommer i många olika produkter i vår miljö. Produktionen och användningen av PUR-produkter ökar. Vid den industriella tillverkningen av PUR kan arbetare exponeras för isocyanater och då drabbas av olika besvär så sThe aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. Biomarkers of TDI and MDI were determined as the corresponding amines, toluenediamine (TDA) and methyle
Popular Abstract in Swedish Vid total höftledsartroplastik är cementering av den konstgjorda ledpannan (cupen) ett allmänt sett välfungerande koncept, men frekvensen av lossning och åtföljande omoperation är fortfarande för hög. En av de viktigaste faktorerna för långtidsöverlevnad av protesimplantat är den initialt uppnådda fixationen och stabiliteten. Den föreliggande avhandlingen omfattar såvälIn total hip arthroplasty cemented fixation of the acetabular component is a generally successful concept, but the rate of aseptic loosening and consequent revision surgery is still too high. One of the crucial factors for longterm implant survival is the initial fixation and stability. This thesis comprises experimental and clinical studies, including radiostereometry (RSA) with up to 5 years fol
The Pegomya terminalis species group is redefined on the basis of the characteristic, exceptionally long and apically strongly depressed female oviscapt. A North American species has once been reared from horsetail (Equisetum sp.), and it is believed that all the species in this group as larvae feed on this unusual diet. The present paper reviews the known Palaearctic species with an identificatio
Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige, men även män kan drabbas. Hos män är det dock en mycket ovanlig cancerform. I Sverige insjuknar cirka 40 män per år av bröstcancer jämfört med cirka 8000 kvinnor per år. Bröstcancer hos män och kvinnor är på många sätt lika. Till exempel är sjukdomstecknen desamma och visar sig oftast som en knöl eller kn
I denna artikel analyseras berättelser av 27 överlevande efter kriget i Bosnien och Hercegovina. Artikelns syfte är att dels analysera markeringar för försoning och oförsonlighet, dels beskriva de försoningsvillkoren som aktualiseras i berättelser. Den interaktiva dynamiken under kriget konstruerar försoningen efter kriget som förbunden med krigstiden. Berättelser om försoning blir en arena för ol
The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. Paper I analyses the performance degradation of d
Popular Abstract in Swedish Det är väl känt att infektioner kan orsaka eller medverka till utveckling av vissa former av cancer hos människan. Cirka 20% av den globala cancerincidensen orsakas av infektioner. Patienter med nedsatt immunförsvar har en ökad förekomst av ett flertal virus-orsakade cancerformer, t.ex. livmoderhalscancer som orsakas av humant papillomvirus (HPV) och levercancer som orsThe identification of infectious agents in cancer has been one of the most rewarding endeavors in cancer research. Currently about 20% of the global cancer burden is linked to an infection. A common characteristic of virus-induced cancer is an increased incidence in immunosuppressed patients, presumably because of impaired host control of virus. Yet non-melanoma skin cancer (NMSC), the cancer that
Ecologists have often compared ecological communities in different areas, for example on different continents. The main interest is that the communities might be more similar in the characters of their species than expected under a null model of random species assortment. We suggest that such a null model should be based only on the species observed across the samples. Species-level convergence an
The concept of historical consciousness has been central in didactic research since the early 1990’s. It has been focused in Swedish history curricula, especially since 1994. Historical consciousness has mostly been used on a macro-level as a theoretical framework. This study aims to analyze whether Swedish history textbooks for lower secondary school have articulated contexts that may develop his
Popular Abstract in Swedish Melanin är ett pigment som finns i många olika slags vävnader. I hud och hår finns två slags melanin, pheomelanin som är typiskt för rödhåriga personer och eumelanin som finns i större mängd i mörkt hår och hud. Konstaterad korrelation mellan hudcancer och solexponering motiverar forskarna att förstå mer om melanin och dess växelverkan med UV-ljus. Man vet att rödhårigaMelanin is an epidermal pigment commonly known to give darker skin coloration under sun exposure. It is also present in the hair, eyes, inner ear and brain. The first function of epidermis melanin is believed to be photoprotective against harmful ultraviolet (UV) light, but the recent increase of skin cancer correlated to an increase of sun exposure questions the properties of melanin. Its presenc
This book hopes to offer an insight into the threats facing the vernacular buildings that survive in the Egyptian Western Desert. It offers a guide to those who wish to get involved in rescuing these buildings, those who re-use them and those who care for them. The first part of the book opens with an overview of the problems experienced in places that are only now becoming vulnerable to the rapid
Popular Abstract in Swedish Denna avhandling syftar till att belysa vilket professionskunnande som blivande lärare ges möjlighet att utveckla under sin högskoleförlagda utbildning och hur detta professionskunnande kan karaktäriseras. Detta belyses genom ett antal forskningsfrågor: Vilka olika undervisningspraktiker konstituerar den högskoleförlagda lärarutbildningen? På vilket sätt upprättas dessaThe starting point for this dissertation was the reform of the school system in Sweden with consequences for teachers´ work and new demands on their professional knowledge. This thesis aims to illuminate the issue of what professional knowledge student teachers are offered during their time in the university, and how this professional knowledge can be characterised. This is carried out with respec
Trimeric soluble forms of HIV gp140 envelope glycoproteins represent one of the closest molecular structures compared to native spikes present on intact virus particles. Trimeric soluble gp140 have been generated by several groups and such molecules have been shown to induce antibodies with neutralizing activity against homologous and heterologous viruses. In the present study, we generated a reco
Background: To offer minimized risk-adapted adjuvant treatment on a community and nationwide basis for patients with clinical stage 1 (CS1) nonseminomatous germ-cell testicular cancer (NSGCT). The aim was to reduce the risk of relapse and thereby reducing the need of later salvage chemotherapy while maintaining a high cure rate. Patients and methods: From July 1995 to January 1998, a total of 232
Chondrules are millimeter sized objects of spherical to irregular shape that constitute the major component of chondritic meteorites that originate in the region between Mars and Jupiter and which fall to Earth. They appear to have solidified rapidly from molten or partially molten drops. The heat source that melted the chondrules remains uncertain. The intense radiation from a gamma-ray burst (GR
Cystatin C and the prion protein have been shown to form dimers via three-dimensional domain swapping, and this process has also been hypothesized to be involved in amyloidogenesis. Production of oligomers of other amyloidogenic proteins has been reported to precede fibril formation, suggesting oligomers as intermediates in fibrillogenesis. A variant of cystatin C, with a Leu(68)-> Gln substitutio
