I svensk rätt har den som erlagt betalning av misstag som huvudregel, enligt principen om condictio indebiti, rätt att få pengarna åter. Huvudregeln motiveras av det faktum att mottagaren inte har någon rätt till de erhållna medlen och därmed inte heller något beaktansvärt intresse av att få behålla dem. Det finns emellertid fall då omständigheterna vid betalningen och händelseförloppet därefter g

Spanjorernas erövring "konflikt", Quechuakulturens strategier av motstånd, men också av anpassning. I modern tid; storskalig urbanisering, ekonomisk ruin och inre väpnande konflikter. Med ett Socialantropologiskt synsätt analyserar bokens författare, Johan Cronehed, det peruanska samhället och dess sociala uppbyggnad. Utifrån Quechuaindianernas etniska tillhörighet visar författaren hur det är m
Popular Abstract in Swedish Ett flertal produkter som framställs inom den kemiska och biotekniska industrin produceras i stora turbinomrörda tankar. Kvaliteten av produkten och utbytet av processen påverkas av blandningsförhållandena i dessa tankar. Blandningsförhållandena i processen påverkas av vätskans hastighet och dess intensitet. I olika regioner av reaktorn, impeller regionen och bulk regiTurbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. Local turbulent flow parameters, the turbulent kinetic energy and the local energy dissipation rate,
Differences between ages, sexes and populations in the timing of migration at Falsterbo, Sweden and in the choice of wintering site among raptors in Scania were investigated. Competition and dominance is the best primary explanation to the results. In most cases the more competitive adults winter north of juveniles and the larger females north of males. Moult strategy is probably one of the most i
Product gas obtained through biomass gasification can be upgraded to hydrogen-rich synthesis gas. The synthesis gas can be further converted to liquid or gaseous fuels. However, the raw product gas contains both gas- and particle-phase impurities that can negatively affect both catalysts and hot-gas filters used for upgrading and cleaning. The present study aimed to characterize, both physically a
In high performance gas turbine engines, the over tip leakage flow driven by the lateral pressure gradient is inevitably induced inside the blade tip gap in the high-pressure stage turbine due to the freestanding airfoil design methodology. To obtain an increasing level of thermal efficiency, the turbine inlet temperature is gradually increased in terms of the Brayton cycle. Hence, the blade tip a
The sun is the most prominent source of directional information in the heading direction network of the diurnal, ball-rolling dung beetle Kheper lamarcki. If this celestial body is occluded from the beetle's field of view, the distribution of the relative weight between the directional cues that remain shifts in favour of the celestial pattern of polarised light. In this study, we continue to expl
The purpose of this book chapter is to investigate to what extent technical function can be protected under European Union (EU) copyright law. Technical function has been explicitly excluded under other regimes of protection in the Union, for example, trademark and design protection law, to avoid overlap (also known as cumulation) between these regimes and patent law. No such statutory provisions
This study sheds light on the causes of failure of economic reform in the Kurdistan Region of Iraq (KRI). It argues that the success of economic reform largely relies on the choices available for ruling authorities as well as their willingness to share power with the people and with each other. Since the birth of the Iraqi state and the KRI the interaction of uncivic traditions, rent seeking, and
A novel design of a biochemical oxygen demand (BOD) biosensor has been developed for on-line monitoring of easily biodegradable organic compounds in aqueous samples. The biological recognition element of the sensor could be easily renewed by injecting new bacterial paste without disassembling the sensor system. The sensor measurements were carried out in the initial-rate mode using a flow injectio
Based on the known age-related loss of Purkinje cells (PC) in the cerebellum, this study focuses on whether a marked loss of PC occurs in individuals of very high age. The inferior olive, which is intimately connected with the cerebellum anatomically as well as functionally, was also studied. The study group included 15 nondemented and basically healthy cases aged 32-104 years. Linear neuronal den
A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contaminated
The International Network for Pediatric Hemophilia (INPH) comprises a group of physicians committed to the unique care of and challenges facing pediatric hemophilia patients. By collaborating on an international level, extensive experience can be shared on current practice, new trends can be discussed and scientifically valid studies can be developed and performed. The three overall objectives of
Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. Om kontrollen brister kan utgången försämras i form av tillstånd såsom preeklIn this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery. ET-1 induced vasoconstriction wa
The chloroplast grana margins of spinach thylakoids were isolated by sonication and aqueous-two-phase partitioning and their electron transport properties examined. Photosystem II and I electron transport activities were measured and compared to the appressed and non-appressed grana core and stroma lamellae, respectively, as well as to whole thylakoids. The results show that the PS II complexes in
The purpose of the study is to offer an interpretation of surrealism as lived experience or, more exactly, an interpretation of the ways in which the Surrealists themselves respond to and conceive of this experience. Thus, emphasis is put on surrealism as event and process, not as a historically limited phenomenon. The prime source of knowledge about this kind of experience, however, remains Surre
