In my research, I have explored various aspects of acetals and their reactivity. Acetals have a central role in carbohydrate chemistry as an inherent functionality and as versatile protecting groups. The first part of the thesis summarizes results on regioselective reductive openings of benzylidene acetals. We thus used deuterium substituted benzylidene acetals and boranes, to investigate stereose
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Vår arvsmassa består av tre olika typer av DNA; kodande, reglerande och ofunktionellt DNA. Det kodande DNA:t används som ritning för hur våra proteiner ska sättas ihop. Proteinerna är de stenar som bygger upp våra celler och ger dem dess specifika funktion, en hudcell är t ex uppbyggd av andra proteiner än en muskelcell. Det är viktigtThe neutrophil store its effector proteins in several distinct types of cytoplasmic granules, developed sequentially during cell maturation. The different subtypes of granules have unique protein content and functional characteristics. The formation of each granule subtype coincides with the biosynthesis of its content. Granule proteins synthesised during the formation of a granule subtype are thu
Popular Abstract in Swedish Skogs- och pappersindustrin är några av Sveriges mest betydande industrier. Mycket av det producerade pappret används till förpackningar och papper har under lång tid varit det dominerande materialet i förpackningsindustrin; en annan viktig industri i Sverige. På senare år har dock pappersindustrin utsatts för hård konkurrens från plastindustrin när det gäller material The paper and packaging industry is a major and important industry in Sweden. The industry is capital intensive with a large investment base and long cycles for renewal and replenishment of machine platforms and other production equipment. Thus, the paper/packaging industry traditionally has a technical product oriented view and product development in the industry is partly made and understood in
Popular Abstract in Swedish Proteiners interaktioner med andra proteiner, med polymerer och med ytor har stor praktisk betydelse inom bland annat proteinrening, läkemedelsformulering och livsmedelsteknologi. Målet med detta arbete är att öka förståelsen för växelverkan mellan proteiner, mellan proteiner och polymerer samt mellan proteiner och ytor, särskilt beträffande de elektrostatiska krafternaInteractions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these syste
Popular Abstract in Swedish Konstant produktion av blodceller i benmärgen krävs för att bibehålla normal syretransport i blodet, sårläkning och ett effektivt immunförsvar. Bakom denna produktion ligger hematopoetiska blodstamceller som regleras av en komplex interaktion mellan dem och deras omgivning. Varje blodstamcell kan med självförnyande celldelningar, där minst en dottercell bibehåller en stHematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions. Such slow kinetics during cell division might reflect a
When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression i
Popular Abstract in Swedish Inrikes- och utrikespolitik kan inte alltid hållas åtskilda. Ett regeringsskifte på nationell nivå kan påverka landets utrikespolitik. På samma sätt kan ett lands utrikespolitiska agerande få inrikespolitiska återverkningar. De kopplingar som finns mellan inrikes- och utrikespolitik kan såväl underlätta som försvåra arbetet för en regering som, per definition, befinner Domestic and foreign policy cannot always be kept apart. A change of Government at national level may impact on foreign policy, and foreign policy adventures sometimes translate into consequences at home. Links between domestic and foreign policy may be limiting as well as enabling factors for Governments who find themselves at the cross-roads between national and international power. This study c
Popular Abstract in Swedish Bakgrund: Diabetes är en sjukdom som karakteriseras av kroniskt förhöjt blodsocker och som obehandlad kan leda till svåra komplikationer i blodkärl, ögon, njurar, nerver m.m. Sjukdomen beror på kroppens oförmåga att producera (typ 1 diabetes) eller svara på effekt av (typ 2 diabetes) hormonet insulin. Det finns ca 150 miljoner personer med diabetes i världen idag, och sType 2 diabetes is characterised by defects in insulin sensitivity, insulin secretion and increased endogenous glucose production. The relative contribution of each of these defects remains controversial. In order to characterise the metabolic defects in various stages of glucose tolerance, the insulin sensitivity and insulin secretion was measured in a large population based study in Finland and
Popular Abstract in Swedish Hållbara matvanor - från jord till bord I Sverige äter vi i genomsnitt 800 kg mat per person och år. Vad och hur mycket vi väljer att stoppar i oss har stor betydelse både för planetens och vårt eget välmående. Den här avhandlingen handlar om hur våra val av livsmedel i den dagliga kosten påverkar miljön och hälsan. Vilken typ av livsmedel vi väljer att äta och dessa Food production and consumption are key drivers of environmental pressures and are essential factors in the promotion and maintenance of health. Production of food occupies more than one third of global land areas and is estimated to be responsible for some 30% of global greenhouse gas emissions. At the same time, we live in a world where nearly one billion people go hungry and even more people su
BACKGROUND: Matrix Gla protein (MGP) is an extrahepatic protein that is dependent on glutamate carboxylation, a vitamin K-dependent process. Its dysfunctional form, desphospho-uncarboxylated-MGP, has been associated with increased arterial calcification and stiffness. The aim of this study was to measure the degree of postoperative carboxylation of MGP and two other Gla proteins in patients schedu
Background Direct cell reprogramming is characterized by the use of defined factors to rewire the transcriptional and epigenetic network of one cell-type into one of a different lineage. We have recently identified the transcription factors PU.1, IRF8, and BAFT3 (PIB) as sufficient to induce a type 1 conventional dendritic cell (cDC1) fate in both somatic and cancer cells.1,2 cDC1 is a rare dendri
Popular Abstract in Swedish Förståelse är ett komplext begrepp. Det används dagligdags utan en motsvarande strikt vetenskaplig definition. Avhandlingen strävar efter att fånga olika aspekter av detta begrepp. Tesen är att förstå handlar om att se ett mönster, i betydelsen att man kan "se" strukturen i en uppgift, en princip eller ett problem. Att se ett mönster innebär också att man uppmärksammar The thesis proposes that understanding is a matter of experiencing a pattern. To experience a pattern involves seeing how a task, principle, or problem space is structured; to attend to the relevant information; and to be able to use that information as it relates to the knowledge domain at hand. The every day concept of understanding, which is a term used in many ways is discussed and it is explo
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
Giving children with disabilities opportunities to explore how to use a powered mobility device is important for their development and learning. Encouraging and supporting exploration of how to set a device in motion and how to use it, has to be performed in harmony with each child and their abilities, needs and motivation. The experience of self-produced movement gives bodily feelings when action

Elekta is a human care company whose solutions and services expresses trustworthy and caring. The aim of the project was to create packaging strategy that reflects the company’s profile, to implement a new packaging design. To achieve this, an analysis of the com
“The management of innovation is inherently difficult and risky, most new technologies fail to be translated into products and services, and most new products and services are not commercial successes. In short, innovation can enhance competitiveness, but it requires a different set of management knowledge and skills from those of everyday business administration” (Bessant et al. 2005 p. 1). The a
