In this work the structure of ternary GaxIn1-xP nanowires is investigated with respect to the chemical composition and homogeneity. The nanowires were grown by metal-organic vapor-phase epitaxy. For the investigation of ensemble fluctuations on several lateral length scales, X-ray diffraction reciprocal space maps have been analyzed. The data reveal a complicated varying materials composition acro

Denna studie behandlar fuktförhållandena i regnexponerade träkonstruktioner, d.v.s. träkonstruktioner som når höga fuktkvoter. Särskilt fokus var på mikroklimatet (klimatet på träets yta) och materialklimatet (träets fuktkvot) i anslutningar. Metoder för att mäta mikroklimatet, d.v.s. våttider på en träyta och varaktighet av vatten i spalter, utvecklades liksom en metod för att mäta fuktkvot nära This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. Methods for determination of microclimate, i.e. the duration of moisture on a wooden surface and the duration of water trapped in gaps between two

We report a measurement of the cross section of single top-quark production in the t-channel using 1.04 fb(-1) of pp collision data at root s = 7 TeV recorded with the ATLAS detector at the LHC. Selected events feature one electron or muon, missing transverse momentum, and two or three jets, exactly one of them identified as originating from a b quark. The cross section is measured by fitting the

In this paper a controller reduction method for discrete-time linear time-invariant systems is described. Using the bounded-real lemma, the proposed method generates reduced controllers with closed loop stability and H-infinity norm performance guarantee. Information of the full controller is used as a basis for reduction using singular value decomposition. This is different from traditional model

This licentiate thesis investigates fiction writing and reading in up- per secondary school in Sweden. Inspired by fanfiction I created a teaching project of derivative writing in which the students in a se- cond-year social science class wrote short stories derived from 20th century novels. They also gave peer response, both orally and in writing. Finally they wrote a reflective text about the pr

Breath alcohol analysis constitutes sufficient material for the prosecution of drunk driving without the need for blood analysis. However, the prevailing method used for breath analysis lacks standardization of several physiological variables that cause a variation of the breath alcohol concentration (BrAC). In this thesis, a novel analyzer which standardizes the BrAC to the water vapour concentra

Assessment of health-related quality of life (HRQoL) in haemophilia is important in order to provide information for clinical decision making and to verify the impact of haemophilia on patients and their families. Advances in haemophilia care and prophylactic treatment have improved HRQoL for the patients and where treatment is available, patients with haemophilia have almost reached the same life

An internal tandem duplication of FLT3 (FLT3/ITD) occurs in approximately 25% of newly diagnosed AML. PKC412 inhibits the growth of leukemic cell lines with FLT3 mutations such as the MV4-11. This study evaluated the in vitro effects of the combination of PKC412 and ara-C or daunorubicin, studying the effect of co-incubation, pre-incubation and sequential incubation of the drugs in patient samples

Gluconobacter oxydans whole cells and membrane fractions in combination with ferrocene mediators were used to study oxidation of ethanol. The efficiency of mediator?enzyme interaction was assessed by the ratio of maximum current to the apparent Michaelis constant (Imax/KM) for saturating mediator concentrations. The bioelectrocatalytic processes were found to be more efficient with membrane fracti

Rules on standing hold the power to enable, as well as to foreclose, intervention in regulatory processes. As such, they determine who may challenge regulatory power, and according to which criteria. This makes standing rules pivotal to any legal system. In the EU context, the Court of Justice of the European Union (CJEU) has been much criticised over the years for its narrow interpretation of dir

Background: Sexual conflict over mating rates may favour the origin and maintenance of phenotypes with contrasting reproductive strategies. The damselfly Ischnura elegans is characterised by a female colour polymorphism that consists of one androchrome and two gynochrome female morphs. Previous studies have shown that the polymorphism is genetic and to a high extent maintained by negative frequenc

Integrated Processors (IP) are meant to supply algorithm-specific cores to a micro-electronic system. They are usually developed separately, and upon success turned into a part, that either by programming or by configuration can be re-used within many systems. This paper looks at architectures for Cellular Neural Networks (CNN) to become realized as IP. First current digital implementations are re

Work in rodents has demonstrated that progenitor transplantation can achieve limited photoreceptor replacement in the mammalian retina; however, replication of these findings on a clinically relevant scale requires a large animal model. To evaluate the ability of porcine retinal progenitor cells to survival as allografts and integrate into the host retinal architecture, we isolated donor cells fro

Popular Abstract in Swedish Osteoporos, eller benskörhet, är en sjukdom som orsakas av störning i skelettets ämnesomsättning. Denna rubbning ger upphov till förändringar i benets uppbyggnad men minskar även mängden benmassa. Osteoporos ger i sig själv inte upphov till besvär men medför en ökad risk för att drabbas av benbrott (frakturer). Dessa frakturer kan vid uttalad benskörhet uppkomma redan vThe number of vertebral fractures has increased during the last few decades.The increase could at least partly be explained by the increasing proportion of elderly in society since these fractures are more commonly found in elderly than in young individuals. Low bone mass and osteoporosis which are also partly related to aging are risk factors for fracture but both age and low bone mass are indepe
