The increasing semiconductor functionality relies on more complex integrated circuits with higher component densities. Miniaturisation and its implications on resource consumption in semiconductor facilities have been fairly well explored in a number of life cycle assessment (LCA) studies, which show that, in spite of the growing product complexity, resource intensities per product unit are gradua
The need to reduce CO2 emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO2 is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power plants PC-plants, Integr
We study deterministic algorithms for gossiping problem in ad hoc radio networks. The gossiping problem is a communication task in which each node of the network possesses a unique single message that is to be communicated to all other nodes in the network. The efficiency of a communication algorithm in radio networks is very often expressed in terms of: max-eccentricity D, max-indegree Δ, and siz
Aims: A study was undertaken to investigate the relationship between country of birth, time in Sweden, and overweight and obesity. Methods: Approximately 4,000 people aged 20-80 participated in a cross-sectional survey in 1994. The ethnic differences in overweight and obesity were analysed in a multivariate logistic regression analysis adjusting for age and education. The effect of number of years
Atypical lipomatous tumor (ALT), an intermediate malignant neoplasm of soft tissues, is characterized by the presence of supernumerary ring and giant marker chromosomes. These supernumerary chromosomes consistently contain amplified 12q-material in association with amplified segments from a variety of other chromosomes. However, a few cases of ALT with other types of chromosomal rearrangements hav
Responding of individuals outside the conspecific range has been largely explained by biases in sensory or cognitive systems toward particular traits or trait values. More recently, it has been shown that such responses might occur if individuals still respond to signal traits that have been lost over time. However, empirical evidence remains scarce. We report a case supporting the latter mechanis
Popular Abstract in Swedish Avhandlingen består av tre delar. Den första, Från utbildningsmarknad till of-fentlig utbildning. Svensk flickskola 1874-1962, behandlar dels integrationen av flickornas sekundärutbildning i den offentliga utbildningsorganisationen, dels förstärkningen respektive försvagningen av denna speciellt genuskodade utbild-ning. Sekundärutbildningen har varit könssegregerad och The thesis is divided into three sections. The first, “From an education market to public education. The Swedish girls’ school 1874-1962”, deals with the integration of girls’ secondary education into the public education system, as well as with the strengthening and weakening of this special, gender-coded education. Secondary education was gender segregated and integration involved a process of s
Attempting to avoid some of the most common methodological problems involved in research on sexual child abuse, we collected data on crimes, perpetrators, and sanctions in all convicted cases of sexual child abuse in a defined population during a 5-year period. This approach provided amply documented and ascertained cases with precise definitions and descriptions of the crimes involved, no clinica
Conclusions. The results indicate that SOM of extreme duration, and maybe also the treatment of SOM, are risk factors for developing permanent hearing loss, both conductive and sensorineural. Objective. Fluctuating or persisting hearing loss of varying degrees is known to accompany secretory otitis media ( SOM). The aim of this study was to detect possible hearing sequelae in young adults who had
Regulatory T cells (Tregs) participate in the control of the immune response. In the human system, an IL-10-secreting, T regulatory type 1 cell (Tr1)-like subset of Tregs can be induced by concurrent cross-linking of the TCR and CD46 on naive CD4(+) T cells. Because many viral and bacterial pathogens, including the major human pathogen Streptococcus pyogenes, bind to CD46, we asked whether this ba
Background: Sotos syndrome is an overgrowth syndrome characterized by macrocephaly, advanced bone age, characteristic facial features, and learning disabilities, caused by mutations or deletions of the NSD1 gene, located at 5q35. Sotos syndrome has been described in a number of patients with autism spectrum disorders, suggesting that NSD1 could be involved in other cases of autism and macrocephaly
High efficiency, environmental friendliness, low operation and maintenance costs, and the lowest possible impact on the environment are some of the requirements of sustainable energy production. In the selection of new power generation systems, a number of steps have to be taken into account in order to meet these requirements. Here, the first law analysis has been implemented and investigated, fo
Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. This thesis puts focus on PAR reduction for wireline communication systems, in particular for the mul
The book contains the first part of an investigation aimed at finding out why it is morally wrong (at least prima facie) to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer
Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LTB4 can bind to two recently cloned cell surface G-protein coupled receptors named BLT1 and BLT2.
Video-on-Demand (VoD) and video sharing services account for a large percentage of the total downstream Internet traffic. In order to provide a better understanding of the load on these services, we analyze and model a workload trace from a VoD service provided by a major Swedish TV broadcaster. The trace contains over half a million requests generated by more than 20000 unique users. Among other
This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. Capillary electrophoresis have been used to determine the dissociation constants of the
The Mesopotamian Marshlands form one of the first landscapes where people started to transform and manipulate the natural environment in order to sustain human habitation. For thousands of years people transformed natural ecosystems into agricultural fields, residential clusters and other agglomerated environments to sustain long term settlement. Moreover, the Mesopotamian Marshlands, located in o

Quantification through image analysis is used in a multitude of fields, and often requires algorithms tailored to the specific task and object that needs to be quantified. The need for flexibility means that such segmentation algorithms are quickly becoming outdated with the advent of convolutional neural networks, which can be trained to fit the specific requirements of the user. One of the field
