Singular and supersingular finite rank perturbations of self-adjoint operators are studied using methods from renormalization theory for quantum fields. It is shown that the ideas from dimensional and Pauli-Villars regulatizations can be applied to determine uniquely certain finite rank supersingular perturbations. Approach is based on the regularization of homogeneous singular quadratic forms.

Popular Abstract in Swedish Under de senaste decennierna har en omfattande omstrukturering ägt rum av den psykiatriska vården. Verksamheterna vid de gamla mentalsjukhusen har avvecklats genom en omfattande nerdragning av slutenvårdplatser. Psykiatrins långtidssjuka patienter skulle återföras till det sociala liv de under lång tid varit avskärmade ifrån. I samband med omorganiseringen till den s kIn the past few decades a comprehensive restructuring of psychiatric care has taken place in Sweden. The activities of the traditional closed institutions have been curtailed through a drastic reduction in the number of beds available in such institutions. "Day treatment," has arisen as a new form of intensive outpatient care in the new, geographically localized psychiatric care of patients with l

Popular Abstract in Swedish Övervikt är ett av vår tids största hälsoproblem, kanske till och med det största. Det finns de som menar att redan idag utgör övervikt globalt sett en viktigare orsak till sjukdom än undernäring och infektionssjukdomar. Framtidsscenariot beskrivs som alarmerande. Folk kommer att i en tidigare aldrig skådad omfattning insjukna i överviktens följdsjukdomar. Medierna harThe prevalence of overweight and obesity is rising each year not only on a national but also on a global level. The future scenario is troublesome. The media are among the most important social institutions in influencing people’s knowledge, perceptions and actions. The media provide citizens with health messages and contribute thereby to their health development. This dissertation deals with two

Objective To compare the performances of 2 methods, telomerase repeat amplification protocol (TRAP) in situ and antibodies to the hTERT protein, in assessing telomerase activity. Study Design TRAP in situ and immunomercial antibody (NCL-hTERT) was performed on 54 body cavity effusions. The results were compared and correlated to diagnosis. Results Thirty-four effitsions from patients with verified

M. A. Persinger (2002) claimed that transcranial magnetic stimulation with weak, complex magnetic fields evokes mystical experiences. However, in a double-blind experiment, P. Granqvist, M. Fredrikson, P. Unge, A. Hagenfeldt, S. Valind., et al. (2005) found no effects of field exposure on mystical experiences (N = 89), though a minority of participants reported spontaneous mystical experiences. Fo

OBJECTIVES: To study bowel ischaemia in transfemorally placed endoluminal grafting (TPEG) for abdominal aortic aneurysms, and any relation to cytokine response or postoperative fever. DESIGN: Prospective not randomised. University hospital setting. MATERIAL: Fourteen cases of conventional surgery and 23 cases of endovascular technique for infrarenal abdominal aortic aneurysm repair. METHODS: Tonom

Sheep and goats are some of the most important animals in prehistoric Scandinavia. The habitus of the animals was used and transformed into cultural categories. Owing to their important and long-term utility they were ritualised during the pre-Christian periods. The role of these animals and the attitudes towards them in and beyond Norse paganism is discussed with habitus perspectives applied to t

Based on the previous finding that 5-hydroxytryptamine (5-HT) co-exists with norepinephrine (NE) in cerebrovascular sympathetic nerve fibers and can be released during electrical nerve stimulation, the postjunctional interaction between the two amines was studied in isolated basilar artery of guinea pig. A low concentration of 5-HT, which in itself has little or no constrictive effect, potentiated

Vascular injuries operated on during a 30-year period (1955-1984) were analyzed. There has been significant increase of such injuries, particularly the iatrogenic types. The total incidence per 100,000 population and year rose from 11.0 to 26.6. Various angiographic and catheterization techniques were responsible for the iatrogenic increase. The noniatrogenic vascular injuries not infrequently wer

AIMS: To compare the incidence of myocardial infarction and death in non-diabetic subjects with and without insulin resistance. METHODS: Population-based prospective cohort study, in Malmö, Sweden, of 4748 non-diabetic subjects (60% women), aged 46-68 years, with no history of myocardial infarction or stroke. The prevalence of insulin resistance was established by the homeostasis model assessment

Survey over media pedagogy within Swedish education

High-order laser guide star performance for the Euro50 telescope is analyzed. Focus anisoplanatism residual errors using multiple LGSs are obtained by numerical simulations. Results calculated for annual mean conditions at the La Palma site show that, considering only focus anisoplanatism, it will be possible to obtain a Strehl ratio of 0.72 similar to 0.82 at 2.2 mum using 13 LGSs. A Strehl ratio

Flow field-flow fractionation (FFF) has previously been used in successful fractionation and characterisation of the ultra-large wheat protein glutenin. The many parameters, which may influence the retention behaviour, especially when analysing extremely high-molecular-mass samples such as glutenin, are here reported. Size determination from the sample retention time, using FFF theory, will as a r

This paper investigates if economic theory can explain variations in piracy behavior between individuals and between countries. It is demonstrated that economic theory explains a notable part of the individual variation in a survey study. Individuals with a low net valuation of an original when a copy is available are more prone to engage in piracy than individuals with a higher valuation. Individ

CFD simulation and experimental tests have been carried out to study the room corner fire growth on combustible wall-lining materials. In the CFD simulation, the turbulent mass and heat transfer, and combustion were considered. The discrete transfer (DT) method was employed to calculate the radiation with an absorptivity and emissivity model employed to predict the radiation property of combustion

The aim of the study was to determine students' self-rated health in relation to sense of coherence and other personality traits. A cross-sectional descriptive design was used with questionnaires as the means of data collection. The study population comprised a randomized stratified sample of students from a small university in southern Sweden. Ethical approval was obtained from the vice chancello

Monitoring of events in the power system provides a great deal of insight into the behavior of the system. Events with impact on the entire power system typically occur in or near the transmission network and are therefore best monitored at transmission system substations. This puts great demands on the equipment and in general restricts the use of the data since it becomes property of the transmi

This article has a threefold purpose. First, it seeks to show how modern rituals among Mi'kmaq traditionalists in eastern Canada are anchored in and derive their rationale from modern reserve existence. Two rituals are described, a kekunit godparent ceremony for a 14-year-old girl and a sweat lodge ceremony later the same evening. Second, the article also provides an example of the paradoxes of "p
