This chapter provides a synthesis of three earlier published studies (Garmy et al. 2012a; Garmy et al. 2012b; Garmy et al. 2013) (survey I) as well as previously unpublished results from a survey conducted in 2013 among students aged 16 (survey II). Objective: The aim was to investigate the effects of sleep, television use and texting and computer habits on overweight, enjoyment of school and fee
Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-
The Rare Isotope Spectroscopic INvestigation at GSI (RISING) project is a major pan‐European collaboration. Its physics aims are the studies of exotic nuclear matter with abnormal proton‐to‐neutron ratios compared with naturally occurring isotopes. RISING combines the FRagment Separator (FRS) which allows relativistic energies and projectile fragmentation reactions with EUROBALL Ge Cluster detecto
Popular Abstract in Swedish Insekter kommunicerar med dofter. De artspecifika kemiska substanser som används mellan individer kallas feromoner. Hos sädesbroddflyet, Agrotis segetum, producerar honan en "parfym", ett sexualferomon som består av flera komponenter, för att locka till sig en hane. På hanens antenner finns lukthår med särskilda motagare, receptorer, som används för att detektera honansA number of analogues of (Z)-5-decenyl acetate (1), a pheromone component of the turnip moth, Agrotis segetum, have been synthesised and tested by using single-cell electrophysiology, in order to investigate the relationships between structure and activity, and to elucidate the interactions between 1 and its receptor. Molecular mechanics and ab initio quantum mechanical calculations have been used
Popular Abstract in Swedish En fråga om liv och hälsa Livstillfredsställelse, personlighet och mortalitet i två äldre populationer Enligt en rapport från FN (2001) kan vi under de kommande 50 åren förvänta oss att andelen äldre över 60 år kommer att fördubblas. Ny och förbättrad teknik, medicinsk kunskap och behandling har utvecklats, vilket innebär att vi i dag överlever i större utsträckning dThe aims of the present thesis were to explore and describe elderly people’s morbidity and experience of symptoms in relation to life satisfaction, personality and mortality. (I, II and III) To learn from the individuals who have high life satisfaction in spite of the fact that they have concurrent medical diagnoses and conditions. (I and III) To reason how positive factors and strengths might hel
Popular Abstract in Swedish Proteiner är livsnödvändiga. I grunden består de av utsträckta kedjor av aminosyror, av vilka det endast finns 20 olika sorter. Dessa är dock nödvändiga för livsviktiga funktioner i organismer, så som att agera som katalysatorer för biokemiska reaktioner, att transportera molekyler och att strukturellt hålla ihop vävnad. Proteiner är ofta specialiserade för deras givna Proteins carry out the instructions encoded in genes and are crucial for many important tasks in the living organism. Often the specific three dimensional structure, or fold, of a protein enables it to carry out a given task. It is an open question whether protein folds have arisen independently or whether mutations to existing protein sequences have caused switches to new folds. In the main part
This study deals with some contested issues regarding prehistoric cultural development in Amazonia and the colonial impact on the native inhabitants of the area. It focuses on the relation between groups belonging the language families of Tupí and Gê, on one hand, and the different ecological zones that they inhabit, on the other. GIS mapping is used to visualise the distribution and movements of
Popular Abstract in English Darwin’s masterpiece “On the origin of species” describes how populations (one group of individuals from the same species that can easily mate with each other and that occupy the same geographic area) evolve through the process of natural selection, which can be shortly abbreviated as the survival of the fittest. More specifically, the individuals within one population The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. ovina to th
