My thesis proposes a new understanding of flexibility in architecture. It investigates reasons for a generic and dull spatial expression of the majority of contemporary buildings. Nowadays, technology and lifestyle are changing so fast that buildings need to accommodate shifting functions. Unfortunately, in pursuit of flexibility, architects design featureless “boxes” which lack intentionality. C
The latest Cyrtograptus lundgreni graptolite Chron (Late Wenlock, middle Silurian) is characterized globally by the Mulde Event faunal extinctions and glacio-eustatic sea-level change. Only in the last decade has it been recognized as one of the most severe extinction events of the Silurian Period. A section spanning the Slite Group-Halla Formation boundary on the islet Ytterholmen off main Gotlan
Popular Abstract in Swedish I avhandlingen beskrivs och analyseras 12 kvinnors skolkarriärer och deras möte med svensk skola. Syftet är att identifiera och belysa mönster, processer och vändpunkter på olika nivåer som utifrån kvinnornas perspektiv mobiliserat respektive begränsat deras skolkarriärer. Kvinnorna kom som flyktingar till Sverige i tonåren och återupptog sin avbrutna skolgång i svenskThe purpose of this thesis is to describe and analyse some foreign women s perspectives on their first meeting with the Swedish school and to identify and illuminate patterns and processes on different levels that facilitate respectively obstruct the development of their school careers. The women arrived in Sweden in their teens and attended Swedish upper secondary school, completed their educatio
In this essay, I discuss two major theoretical discourses of modernity, namely, of classical modernity and postmodernity. Moreover, I aim at a proposition of a possible historical relation between those two discourses of crucial importance to modernity’s intellectual history. This historical connection is founded on what I call the principle of insufficient reason. The principle of insufficient
During the last decade there has been an increase in the use of horizontal organizational relationships (HORs) such as strategic alliances, shared services, and outsourcing. Studies accentuate the unstable, fragile nature of HORS and the importance of directing attention to how these arrangements are formed and how and why they change. The aim in this study is to explore control problems of HORs a
Despite 3 decades of basic and clinical studies, there is still no dopaminergic cell therapy for Parkinson's disease. Several arguments have been put forward why this approach, so far tested with transplantation of human fetal mesencephalic dopamine-rich tissue, will never be of clinical use and should be abandoned: (1) Lack of efficacy in 2 sham surgery-controlled trials; (2) occurrence of troubl
A myoelectric control system for prostheses was developed and evaluated on six healthy subjects. These were able to control a computer-animated hand in real-time with a 20 Hz update rate. A data glove, equipped with joint angle sensors, was used to train the system and to evaluate the continuous predictions of joint angles. A linear envelop filter was used for EMG signal pre-processing and the rec
Macroarray analysis was used to compare equal amounts of cDNA from wild-type and rd/rd (retinal degeneration) mice, collected at P90 when photoreceptor degeneration is virtually complete. A stronger signal for the glycolytic enzyme phosphoglucose isomerase (Gpi1) was observed in the rd/rd sample. Extracellularly, Gpi1 may act as a cytokine, independently described as neuroleukin and autocrine moti
A study was undertaken to measure the effects of conspecific density on the growth, mortality and deformity rate of yellowtail kingfish Seriola lalandi Valenciennes during the first feeding period. Newly hatched larvae were stocked in replicate tanks at initial densities of 40, 60 and 100 ind. l(-1) until 30 d post-hatch (DPH). Live prey was administered at frequent intervals in an effort to maint
Matrix metalloproteinases (MMPs) play an important role in the pathological processes of degradation of extracellular matrix and destruction of basement membrane, which leads to tumor invasion and metastasis. In the present study, we investigated membrane-type 2 MMP (MT2-MMP) expression pattern in esophageal cancer tissues collected from 103 patients, and explored MT2-MMP expression pattern in cor
Popular Abstract in Swedish Sjukdomar hos äldre har ofta annan sjukdomsbild än motsvarande sjukdom hos medelålders och yngre. Till exempel är symtomen är ofta mindre tydliga, äldre har ofta flera samtidiga sjukdomar som ger en komplex sjukdomsbild, dessutom kan ett ”mindre allvarligt” sjukdomstillstånd föra med sig betydande besvär pga annan samtidig sjukdom. Detta gäller även för depressionssjukdStudies have found that depressive states in old age that do not fulfil the criteria for major depression are clinically important depressive states. These depressive states are common in primary care patients. Therefore, studies of late-life depression from a primary care perspective are needed. A depressive rating scale, Hopkins Symptom Checklist-25 (HSCL-25), was used in a community survey in 1
Kultur och värderingar är ett allt mer omdiskuterat område i urvalsprocesser samtidigt som egenskaper och kompetenser krävs för att en person ska betraktas som kvalificerad för en anställning. Valet av frågor och bedömningsunderlag ligger till grund för anställningsbeslut och är därför av stor betydelse i intervjusammanhang. I denna studie genomfördes en attitydmätning för att undersöka vad yrkesv
This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-w
In the quest to find a ‘least cost solution’ for climate change mitigation that do not interfere with business-as-usual, carbon trading and PES schemes were introduced. PES schemes with carbon forestry projects are implemented in the Global South as a win-win-win tool for climate change mitigation and sustainable development. In this thesis, the Ugandan carbon forestry project Trees for Global Ben
Konsekvenser av och attityder till nedskräpning i stadsmiljö Nedskräpningen som förekommer på gator, torgar och parker kostar för samhället, skadar vår hälsa, förstör vår miljö, bidrar till ökad nedskräpning och upplevs som otrevliga och otrygga områden av många människor. Att det är förbjudet att skräpa ned på offentliga platser ses som en självklarhet enligt lagstiftningen. Men resultatet av
The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). There are more than 500 000 off-grid RBSs in the world which are powered

A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs. However, high-efficiency PAs tend to be non-linear, and PAs working in the linear region might ha
För att svensk järnvägsinfrastruktur skall kunna vara konkurrenskraftig i jämförelse med mindre miljövänliga alternativ krävs kapacitetsutbyggnad och hastighetsökning av det svenska järnvägsnätet. Vid hastigheter över 200 km/h finns krav på att dynamiska analyser behöver utföras. För vissa brotyper, exempelvis samverkansbroar med ändskärmar, är det svårt att påvisa acceptabel vertikal accelerationFor Swedish railway infrastructure to be competitive compared to less environmentally friendly alternatives, capacity expansion and speed increase of the Swedish rail network are required. At speeds above 200 km/h, dynamic analyses are required by code. For some bridge types, such as composite bridges with end screens, there are difficulties in meeting the requirements for vertical acceleration in
