Introduction. Electrodialytic processes have become relevant technology in promoting sustainability within the food industry. Bipolar membrane electrodialysis (EDBM) offers an efficient and eco-friendly alternative for skim milk (SM) acidification, eliminating the need for added acids that affect milk properties and mineral composition [1-2]. In this study, the fouling behavior of bipolar membrane
This thesis clarifies and highlights how selected parts of Swedish law in the field of health care relate to different ways of understanding events that have caused or could have caused patient injury: a systems perspective and an individual perspective, respectively. It thus examines how the law and its application relate to conflicts between supporting openness and learning based on a systems pe
Popular Abstract in Swedish Denna avhandling fokuserar på effekterna av spin-ban växelverkan (SBV) i nanometerstora ferromagnetiska metallpartiklar. SBV kan betraktas som en interaktion mellan två magnetiska moment, varav det ena utgörs av elektronens spin och det andra är orsakat av elektronens egen banrörelse. Banrörelsens bidrag bygger på faktumet att ett magnetiskt moment genereras av elektrisThis thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. At the core of the thesis lie four original papers, collected in Part II, which are presented and s
Wind damage is one of the most economically and ecologically significant natural disturbances in European forests, yet the cloud cover that follows major storms routinely blocks optical satellite acquisitions for weeks, precisely when rapid damage mapping is most valuable. Synthetic aperture radar (SAR) circumvents this limitation through all-weather imaging, but pixel-level windthrow detection fr
Verifiering av tekniska egenskaper inför återbruk av prefabricerade massiva betongbjälklag är en komplex process som kräver projektspecifika bedömningar. I detta arbete har ett tillvägagångssätt tagits fram för ett mer generellt fall i hopp om att kunna appliceras på en större brädd av olika projekt, under premissen att det anpassas efter projektsspecifika förutsättningar. Tillvägagångssättet har The verification of technical properties associated with the reuse of prefabricated solid concrete floor slabs is a complex process that must be assessed on a project-specific basis. In this thesis an approach has been developed for a more general case, with the intention that it may be applied across a broader range of projects, provided that it is adapted to project-specific conditions. The appr
Detta examensarbete undersöker hur materialanvändningen i platsgjutna betongbjälklag och betongväggar i flerbostadshus kan minskas genom att separera den bärande betongen från funktioner som inte behöver lösas inom själva den bärande konstruktionsdelen. Studien motiveras av betongbyggandets höga klimatpåverkan och av indikationer på att materialanvändningen i betongkonstruktioner har ökat över tidThis thesis investigates how material use in cast in situ concrete slabs and walls for multi-storey residential buildings can be reduced by separating the load-bearing concrete from functions that do not have to be solved within the structural member itself. The study is motivated by the high climate impact of concrete construction and by indications that material use in concrete structures has in
Observations from the Arctic Summer Cloud Ocean Study (ASCOS), in the central Arctic sea-ice pack in late summer 2008, provide a detailed view of cloud-atmosphere-surface interactions and vertical mixing processes over the sea-ice environment. Measurements from a suite of ground-based remote sensors, near-surface meteorological and aerosol instruments, and profiles from radiosondes and a helicopte
Popular Abstract in Swedish Summary in swedish Perinatal dödlighet bland invandrare från Afrikas Horn. Vikten av erfarenhet, rationellt tänkande och traditioner vid riskbedömning av gravida invandrarkvinnor. Avhandlingen visar att barn till kvinnor i invandrargrupper från Afrika söder om Sahara (majoriteten från Somalia och Etiopien), har högre perinatal dödlighet jämfört med barn till svenska kThis thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. After adjustment for risk factors, however, the finding only held true for a subgroup of women from Ethiopia and Somalia (ES). In searching for the mecha
Popular Abstract in Swedish I denna avhandling studerades artrikedom, rörelsemönster och utdöenden bland fjärilar och solitära bin. Under senare år har det uppmärksammats att antalet arter av insekter minskar i en alarmerande takt. Fjärilar, bin, blomflugor m.fl. blir allt färre. Eftersom insekterna utgör en stor del av arterna på jorden och dessutom har viktiga funktioner i ekosystemen, som t.ex.During recent decades, concern about the loss of biodiversity has increased. To change this negative trend there is an urgent need for effective conservation measures and there are ample evidence that conservation of organisms without an understanding of their ecology and behaviour is impossible. At the Kullaberg Nature Reserve in the south-western part of Sweden butterflies exhibited a disastrous
Sweden is part of a small European minority in the perceived societal gain of PPP. After a pilot PPP project in late 1990’s no additional project has been started in Sweden. Although there is interest from both public infrastructure clients and construction companies the national government has very clearly stated that infrastructure projects should be procured in a traditional way where all fundi
Popular Abstract in Swedish Komplementsystemet är ett system bestående av cirka 35 proteiner i blodet och på cellytor, som ingår i kroppens medfödda immunförsvar. Det är ett mycket viktigt men också explosivt system, potentiellt skadligt för kroppens egna celler, som kräver strikt reglering. Denna avhandlings huvudaktör, C4b-bindande protein (C4BP), nedreglerar komplementsystemet. C4BP har en ovanThe subject of this thesis is plasma protein C4b-binding protein (C4BP). C4BP is an important regulator of the classical pathway of the complement system, a cascade-like system comprised of over 35 proteins, which partakes in the defence against micro-organisms and is involved of clearance of immune-complexes and apoptotic cells. C4BP contains two different types of subunits, seven identical alfa-
Aim To assess statistically the relative importance of climate and human impact on forest composition in the late Holocene. Location Estonia, boreonemoral Europe. Methods Data on forest composition (10 most abundant tree and shrub taxa) for the late Holocene (5100-50 calibrated years before 1950) were derived from 18 pollen records and then transformed into land-cover estimates using the REVEALS v
The degradation kinetics of normal and branched chain butyrate and valerate are important in protein-fed anaerobic systems, as a number of amino acids degrade to these organic acids. Including activated and primary wastewater sludge digesters, the majority of full-scale systems digest feeds with a significant or major fraction of COD as protein. This study assesses the validity of using a common k
l-DOPA-induced dyskinesia (LID) is a major complication of the pharmacotherapy of Parkinson's disease. Emerging approaches to the treatment of LID include negative modulation of metabotropic glutamate receptor type 5 (mGluR5) and positive modulation of serotonin receptors 5-HT1A/1B. We set out to compare the efficacy of these two approaches in alleviating the dyskinesias induced by either l-DOPA o
Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. Several observ¬ations regarding the outcome of therapy have prompted the use of higher absorbed doses by administering larger amounts of activity than those indicated in standard protocols.
Popular Abstract in Swedish Bose-Einsteinkondensat är de kallaste system människan känner till, och de styrs helt av kvantmekaniska lagar. Därför har de många speciella egenskaper, som bland annat visar sig under rotation. De kan till exempel inte rotera med vilken hastighet som helst, utan bara vissa specifika hastigheter är tillåtna. Vidare kan man - under vissa omständigheter - få ett Bose-EinsIn this thesis, I explore the behavior of rotating ultra-cold Bose gases, by diagonalizing the Hamiltonian. This method has the advantage of being exact in the limit of weak interactions, and thus is a useful complement to the more commonly used Gross-Pitaevskii (GP) equation, which relies on a mean-field approximation. It is generally known that an ultra-cold Bose gas shows some remarkable proper
The main aim of the present thesis is to demonstrate the efficient quantum memories for light employing coherent processes in rare-earth-ion-doped crystals. Rare-earth (RE) ions between lanthanum, with atomic number 57, and lutetium, with atomic number 71, have a partly filled 4f shell, which is spatially inside the full shells 5s, 5p, and 6s. Therefore, 4f-4f transitions are shielded from environ
Our aim with this report is to discuss vehicle fuels from a wide perspective of sustainability. Biofuels and electricity are analyzed and compared to fossil vehicle fuels. Our goal is to try to point out the circumstances under which vehicle fuels can be reasonably perceived as sustainable, and which systems we should develop and which we should avoid. The all-embracing conclusion of this study is
The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”. Implanted bioele
