Improved reliability of ultrasonic surveillance of abdominal aortic aneurysms
OBJECTIVES: Small abdominal aortic aneurysms (AAA) are usually managed conservatively by serial ultrasound examinations to assess size. The development of the size of the AAA will determine whether the patient is a candidate for surgery. The precision of measurement is therefore of considerable importance. The aim of this study was to evaluate the accuracy and the reproducibility of a newly develo
Long-term history of land-use and vegetation at Ire, an agriculturally marginal area in Blekinge, south Sweden
Pollen records from a small lake and a small peatland at Ire in northern Blekinge, Sweden, reveal that until A.D. 300 there was a mixed deciduous type of woodland dominated by Quercus, Tilia and Corylus, with Betula, Pinus, Populus, Fraxinus, Ulmus and Acer as important constituents. The first, but weak, signs of human influence on the vegetation are detected around 2300 B.C. At this time, the are
Response to directional light by leaves of a sun-tracking lupine (Lupinus Succulentus)
Experiments were done to examine the phototrophic response of sun-tracking leaves of Lupinus succulentus Dougl. to fixed beams of white and broad band light. Upon irradiation with 15 W m-2 white light that struck the laminae at an angle of 45°, there was a 45–60 min lag period prior to leaf movement. The greatest rate of movement was 15° h-1, and reorientation ceased when leaves attained a positio
Connectivity can be used to identify key genes in DNA microarray data: a study based on gene expression in nasal polyps before and after treatment with glucocorticoids
Conclusions. The presented analysis of nasal polyposis using connectivity based on the PubGene literature co-citation network demonstrates that this tool can be used to identify key genes in DNA microarray studies of human polygenic diseases. Objectives. DNA microarray studies of complex diseases may reveal differential expression of hundreds of genes. According to network theory and studies of ye

Essays on Incomplete Information in Financial Markets
Popular Abstract in Swedish Avhandlingen består av tre essäer som behandlar effekterna av inkomplett information i de finansiella marknaderna. Av dessa essäer är två teoretiska och en är huvudsakligen empirisk. Samtliga essäer undersöker effekterna av parameterosäkerhet, och de använder sig av kontinuerliga modeller. Den första essän, "The Effect of Information Quality on Optimal Portfolio ChoiceThis thesis consists of three essays on incomplete information in financial markets, two of which are theoretical, and one that is mainly of an empirical nature. All three essays concern parameter uncertainty, and they employ a continuous-time framework. The first essay, "The Effect of Information Quality on Optimal Portfolio Choice," analyzes the portfolio choices made by three types of agents,
Älskad och förnekad : Flickboken i Sverige 1945-65
The tradition of writing books specifically for girls came to an abrupt end in the middle of the 1960's. In Sweden this was a turbulent decade when society changed in many ways, and equality between the sexes was a key word. The old girls' and boys' books were replaced by "the modern book for young people", which, it was proclaimed, should be up-to-date, discuss real problems, break taboos, and ap

Severe retinopathy in type 1 diabetic patients is not related to the level of plasma homocysteine
The vascular-injuring amino acid homocysteine was previously shown to be increased in plasma in type 1 diabetic patients with clinical signs of nephropathy. Previous studies have also shown an inconsistent relationship between the development of diabetic nephropathy and retinopathy, indicating different pathogenetic mechanisms. In this study, plasma homocysteine was measured in 25 type 1 diabetic

Production of omega mesons at large transverse momenta in p+p and d+Au collisions at root S(NN) = 200 GeV
The PHENIX experiment at RHIC has measured the invariant cross section for omega-meson production at midrapidity in the transverse momentum range 2.5 < p(T)< 9.25 GeV/c in p+p and d+Au collisions at root s(NN) = 200 GeV. Measurements in two decay channels (omega ->pi(0)pi(+)pi(-) and omega ->pi(0)gamma) yield consistent results, and the reconstructed omega mass agrees with the accepted value withi
God vård på lika villkor vid hjärtinfarkt i dagens Sverige. Geografiska skillnader i dödlighet utan betyd
I TV-programmet »Uppdrag granskning« påstods nyligen (16 mars 2004) att det är livsviktigt för patienter med akut hjärtinfarkt att bo i närheten av rätt sjukhus. Frågan är när geografiska skillnader i dödlighet blir så pass stora och säkra att de har betydelse för den enskilda patienten. När man studerar skillnader i dödlighet mellan olika sjukhus bör man om möjligt också beakta landstingens roll.It is a known fact that the 1990s brought a decrease in mortality after myocardial infarction in Sweden but that differences in mortality rates following myocardial infarction still remain between the Swedish counties. Unresolved, however, are questions as to what these inter-county differences mean for the individual patient and what role hospital care plays in this context. We analysed all patie
Flexible Scheduling Methods and Tools for Real-Time Control Systems
This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. One approach to achieve flexibility in the run-time scheduling of control tasks is feedback sched
Planning of Environments for People with Physical Disabilities Using Computer Aided Design
In the area of environment adaptations for people with physical disabilities, it is of vital importance that the design is optimized considering the human-environment interactions. All involved persons in such a planning process must be given sufficient support in understanding the information, so that everyone can participate actively. There is an apparent risk that discussions will be kept betwe

In vitro activity of synthetic antimicrobial peptides against Candida
Yeast-like fungi are the most common cause of fungal infections in humans. Actually, in the age of opportunistic infections and increasing resistance, development of modern antifungal agents becomes a very important challenge. This paper describes synthesis and antimicrobial assay of four naturally occurring peptide antibiotics (aurein 1.2, citropin 1.1, temporin A, uperin 3.6) and three chemicall
