Popular Abstract in Swedish Klorofyllsyntes är en viktig process i naturen. De gröna pigmenten utgör en viktig del i fotosyntesen där de absorberar och överför solenergi till fotosyntetiska reaktionscentra. Magnesium kelatas katalyserar insättandet av en magnesium (II) jon i protoporfyrin IX, vilket är det första specifika steget i klorofyllsyntesen. Magnesium kelatas består av tre proteiner, som The biosynthesis of chlorophylls is an important process in nature. The green pigments play a fundamental role in absorbing and transferring solar energy to the photosynthetic apparatus. This thesis elucidates the role and function of the enzyme magnesium chelatase, which catalyses the insertion of magnesium (II) into protoporphyrin IX and is the first committed enzyme of the chlorophyll biosynthe

Popular Abstract in Swedish Trots omfattande forskning är förståelsen för diffus hjärnpåverkan efter hjärtkirurgi och dess kliniska betydelse ofullständig. Avhandlingens syfte har varit att kartlägga kognitiv funktion efter kranskärlskirurgi och undersöka de kliniska konsekvenserna därav.

Popular Abstract in English Bolivia, as with other Latin American countries, is considered to be in an epidemiological transition due to the continued persistence of infectious diseases, and nutritional deficiencies related to poverty and food insecurity, together with an increase in chronic non-communicable diseases mainly related to lifestyle factors. The work presented in this thesis was focuseThe synergistic relation between nutritional deficiency and infection may have negative effects on the immune system, making individuals more vulnerable to infection. Zinc can affect the resistance to infections by modulating cytokine release, and by acting as a cofactor of thymulin, which induces the differentiation of immature T lymphocytes. To investigate the modulation of the immune response b

1. Som en reaktion mot herrnhutismens ”blandade” lära definierades den rätta läran av Schartau och än mer av hans efterföljare ofta mycket snävt. Den så kallade bokstriden som bröt ut när andra bandet av Schartaus brev 1830 publicerats, avgränsade negativt schartaulärjungarna genom att de undvek de flesta uppbyggelse- och andaktsböcker. Schartau drev på den konfessionalisering som från omkring 182

Popular Abstract in Swedish Fantasygenrens många främmande och fantastiska platser ger inte bara handlingen en exotisk kuliss utan är tätt knutna till hur berättelserna är uppbyggda. I Stefan Ekmans doktorsavhandling Writing Worlds, Reading Landscapes: An Exploration of Settings in Fantasy visas hur miljön i fantasy är lika viktig som persongalleriet och intrigen. Fantasy är en genre som sätter väIn fantasy literature, the setting is as important to the story as are characters and plot; but although many fantasy scholars have pointed this out, there is very little criticism that explores the role of the setting in fantasy. The aim of this study is to use a topofocal (place-focused) perspective to examine four aspects of the fantasy setting, including the way in which settings function in t

Children spend a large percentage of their day with their classmates in school. Classmates are not only co-workers, but also individuals interacting socially as friends. The understanding of group affiliation and friendship interaction in school is of great importance to social work in school because of its implications on children’s wellbeing and academic performance.

Bipolaris sorokiniana is the causal agent of multiple diseases on wheat and barley and is the primary constraint to cereal production throughout South Asia. Despite its significance, the molecular basis of disease is poorly understood. To address this, the genomes of three Australian isolates of B. sorokiniana were sequenced and screened for known pathogenicity genes. Sequence analysis revealed th

Cirka 1000 barn föds med hjärtfel i Sverige varje år och idag överlever de flesta och uppnår vuxen ålder. Det finns uppskattningsvis 2.3 miljoner vuxna med medfött hjärtfel i Europa idag, en siffra som förväntas öka. Samtidigt har prevalensen av patienter med komplexa medfödda hjärtfel också ökat de senaste 10 åren. Det finns således ett behov av att öka kunskapen om patofysiologin vid dessa sjukdAround 1000 children are born with a heart disease in Sweden every year and today most of these children survive and reach adult age. There are around 2.3 million grownups with congenital heart disease in Europe today, a number that is expected to continue to increase. Further, the prevalence of patients with complex malformations has been growing significantly the last 10 years. There is thus a n

Popular AbstractI avhandlingen undersöks den ekonomiska omvandlingsprocess som skett i Sverige sedan mitten av 1970-talet. Av speciellt intresse är hur och varför de fördelar som företag och branscher åtnjuter på grund av samlokalisering med andra ekonomiska aktörer (så kallade agglomerationsexternaliteter) varierar över olika faser av ekonomisk omvandling. Avhandlingen baserar sig på de framsteg This thesis investigates the process of economic transformation taking place in Sweden since the mid 1970s. Especially, it is concerned with how and why benefits that firms and industries draw from regional co-location with other actors (agglomeration externalities) vary over stages of economic transformation. Drawing on recent findings within the fields of evolutionary economics and evolutionary

Popular Abstract in Swedish I en komponent som utsätts för upprepande på- och avlastningar, d.v.s. cyklisk belastning, kan defekter i form av sprickor initieras och börja växa. Detta fenomen kallas utmattning och kan leda till haveri med potentiellt katastrofala följder. Det är därför viktigt att förstå fenomenen som ligger bakom utmattning och att ha tillförlitliga modeller för att förutsäga livsUnderstanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. This thesis deals with the growth of fatigue cracks subjected to high load amplitude

Popular Abstract in Swedish Under de senaste decennierna har förhoppningar om en ökad andel manlig personal i förskolans verksamhet uttryckts från samhällets sida. Förhoppningarna har dock inte infriats och antalet yrkesverksamma manliga förskollärare var cirka två procent i slutet av 1990-talet. Denna könsmässigt underrepresenterade grupp, som i sin yrkesutövning befinner sig i en kraftigt könsmäThe aim of this study is to describe and analyse the situation of male teachers in the day-to-day work of pre-school, taking into account the fact that men are underrepresented in this profession. The methodic field is qualitative. Video recordings and interviews have been carried out with the fourteen male pre-school teachers who have participated in the project. Some of these men work together w

Popular Abstract in Swedish I september 1989 kom det till kanadensiska mi’kmaqindianers kännedom att ett enormt granitbrott (ett av de tre största i världen) planerades att öppnas vid Kellys Mountain på ön Cape Breton i östra Kanada. Mi’kmaqtraditionalister organiserade genast en fredlig trumceremoni på berget och en talesman deklarerade att det planerade granitbrottet var en förolämpning mot bådeThis dissertation seeks to explore historical changes in the lifeworld of the Mi’kmaq Indians of Eastern Canada. The Mi’kmaq culture hero Kluskap here serves as a key persona in discussing issues such as traditions, changing conceptions of land, and human-environmental relations. In order not to depict Mi’kmaq culture as timeless, two important periods in its history are examined. The first study

Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions.
