Popular Abstract in Swedish Under det senaste decenniet har utvecklingen i Sverige inneburit en ökad press på den kommunala sektorn vars roll och uppgifter i samhället har ifrågasatts. Ett återkommande ämne för debatt är betydelsen av politiskt inflytande i förhållande till behovet av effektiv produktion av offentlig service. I denna avhandling studeras vilka möjligheter en enskild kommunal försörThe aim of the study is to improve the understanding of strategy in politically governed organisations. From the perspective of a specific responsible authority the main purpose of the study is to describe and analyse how strategies emerge and develop. Competitive tendering and inter-municipal co-operation, has been studied as a two principally different strategic approaches to reduce costs and st

In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. Two types of failure management strategies can be applied: proactive asset condition assessment and reactive failure detection and location. Currently available con

Popular Abstract in Swedish Epilepsi är ett tillstånd med återkommande attacker av abnorma, repetitiva och synkrona urladdningar i det centrala nervsystemet. Kindling är en djurmodell för en svårbehandlad form av epilepsi (med komplexa partiella anfall) som ofta har sitt ursprung i det s. k. limbiska systemet. Kindling är en mycket vällämpad modell för studier av utvecklingen av den ökade retbarheEpilepsy is a syndrome characterized by recurring attacks of sudden, excessive and synchronous discharge in populations of cerebral neurons. Kindling is an animal model for complex partial epilepsy, and is particularly useful for studies on the development of the abnormal excitability underlying the generation and spread of epileptic seizures. Here we have used the kindling model to investigate me

Popular Abstract in Swedish De två studier som presenterats i föreliggande avhandling avser att belysa sambandet mellan den administrativa organisationen av skolan och rektors möjligheter att leda den pedagogiska verksamheten. Vidare avser den att granska sambandet mellan lärargruppens anda och tillfredsställelsen med rektors ledarskap. Studierna avser också att granska hur rektors förmåga att etaThe thesis focuses on the elementary school principal’s formal responsibility and role in connection with his spatial and psycho-social nearness to the teachers. On one hand it is a comparison between schools in Sweden and Iceland, while on the other hand it is a case study of the principal’s leadership in several different school organisations. These studies are based on the theory that even if t

Ever since its first conception in 1907 by Bergson, "complementarity" has come to represent extremely wholistic situations, for which fragmentability into parts turn out unsuccessful. In 1927, Bohr used the term complementarity within quantum mechanics, with profound consequences, for a principally unsuccessful fragmentability into independent observability and definability concepts. The paper ob

Popular Abstract in Swedish Fåglar har fascinerat människor i århundraden. Färgen på deras fjädrar, deras flyghöjd och deras förmåga att fånga små byten har skapat den allmänna uppfattningen att fåglar har en fantastisk syn. Föreställningen att fåglar har skarpare syn än människor är väletablerad hos jägare och fiskare och finns att hitta i litteraturen. Det finns emellertid tusentals fågelarter oAvian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. In this thesis I present four studies on different aspects of spatial vision in parrots, procellariiform seabirds and birds of prey. In Paper I we studied retinal g

1 We studied the effects of a thromboxane A2 receptor (TP receptor) antagonist, ICI-192,605 (0.5mgkg-', i.v.) and a selective thromboxane (Tx) synthetase inhibitor, OKY-046 (30mgkg-1, i.v.), on airway responses induced by leukotriene D4 (LTD4; 0.2 nmol) or prostaglandin F2a, (PGF2,; 20 nmol) instilled via the airways route to anaesthetized guinea-pigs. For a comparison, airway responses to a TxA2-

Popular Abstract in Swedish Hur kommer det sig att liknande reformprogram återfinns i olika länder? Varför väljs vissa idéer framför andra? Avhandlingen syftar till att öka förståelsen av så kallad policydiffusion, spridning av olika typer av policy, och den dynamik som omgärdar spridningen. Detta görs genom att undersöka hur externa, eller utländska, idéer integreras och översätts i en ny omgivniSimilar policies may be found in different countries. This, in turn, is an indication that policies travel. But why are certain policies imitated while others are not? The author seeks to further our understanding of policy diffusion and its dynamics by investigating how foreign ideas are integrated and translated into new contexts, and how these imported ideas influence national policymaking and

This doctoral dissertation concerns two-dimensional frequency estimation for modal analysis of single-input multiple-output impact responses from circularly cylindrical objects. The application is within detection of internal defects in trunks of spruce. The material consists of impact responses from 94 trees, with 66 sound and 28 in various stages of decay. Paper I proposes that modal analysis o

Popular Abstract in Swedish Byggbranschen står inför stora utmaningar i att möta behovet av nya bostäder samtidigt som renoveringsbehovet av flerbostadshus är stort. Man beskylls ofta för bristande kvalitet och höga kostnader. Industriellt byggande har framförts som en lösning till problemen. I ett projekt på Lunds Universitet har två tillämpningar för industriellt byggande studerats: trähusbygganIndustrialized construction has over the years taken different expressions and gone through different phases depending on where inspiration has come from. In this project, industrialized construction has been studied in two applications: timber house manufacturing and renovation of multi-family houses. In Sweden industrialized production of timber houses is relatively strong in the housing sector

In the present project, a new experimental method enabling Planar Laser-Induced Fluorescence (PLIF) measurements in bubbly gas-liquid flows is presented. Due to reflection and refraction of the laser light, the bubbles will cause an uneven and unknown distribution of light intensity in the measurement plane. Introducing a tracer as a “reference” tracer with a known concentration, this can be compe

Popular Abstract in Swedish Trastsångarnas MHC gener i klarspråk Inuti kroppen ser vi väldigt lika ut allihop; men om mina njurar skulle sluta att fungera är det inte alls säkert att just du kan donera en njure till mig. Detta beror på att våra transplantations-gener eller s.k. MHC- (Major Histocompatibility Complex) gener är olika, och vid en transplantation måste många av donatorns och mottagarIn vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. The importance in the immune defence and the polymorphism make these genes interesting to study from an ecological and evolut

It is shown that the isoscalar strength in the energy region just above the low energy threshold, which is created by exciting particles to the continuum in nuclei far from β-stability lines, can be reduced by the attractive coupling to isoscalar shape oscillations. This is in contrast to the well known fact that in β-stable nuclei low lying isoscalar particle hole strengths are always increased b

Background The aim of this review article is to examine the evidence in the literature with regard to the safety of exercise in pregnancy. Material and Methods A literature search revealed fourteen randomised controlled trials which were systematically reviewed. The outcome measures looked at were both short and long term consequences of training in healthy pregnant women. Results The methodo

In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c

Popular Abstract in Swedish Funktionen hos hemoglobin från ryggradslösa organismer är mer varierande än motsvarande för ryggradsdjur, vilket möjligen speglar de mer mångfasetterade behoven inom den förra gruppen. Hemoglobin har strukturella likheter med andra hemproteiner/enzymer och uppvisar även överlappande enzymaktiviteter, med funktioner utöver transport och lagring av syre. Under syrefattigThe function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. When subjected to oxygen deficient conditions, the obligate ae

Popular Abstract in Swedish Denna avhandling undersöker dagvatten som en resurs i svensk urban miljö. Fokus har varit öppna dagvattensystem för flödeskontroll och uppsamlingssystem för regnvatten. För att analysera realiserandet av öppna dagvattensystem, presenteras två fallstudier; Augustenborg i Malmö och Bäckaslöv våtmark i Växjö. De kvarhållande och fördröjande effekterna som uppnås med gröna This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. The retention and detention effects of green-roofs have been

In this thesis I offer a unified syntactic account of the small clauses involved in Swedish object-with-infinitive constructions (ECM), object predicative constructions and absolute constructions. In the present framework, this similarity is conceptually appealing and is also supported by empirical data. My account extends to other types of small clauses as well. I claim that small clauses are pro
