The complex world of proteins: Structure, function, and oligomerization of frataxin

Popular Abstract in Swedish Bakgrund Järn (med den kemiska beteckningen Fe, från latinets ferrum) är känt för de flesta som en beståndsdel i till exempel stål. Det många inte vet är att järn är nödvändigt för liv, så som det ser ut på jorden idag. Men det finns en annan sida av myntet: järn kan nämligen också vara giftigt. Som de allra flesta känner till rostar järn i närvaro av syre och vatten.Patients suffering from the deadly progressive neurodegenerative disease Friedreich's ataxia have reduced levels of expression of the protein frataxin. Yeast frataxin has been extensively studied in vitro, and has been shown to deliver iron to heme and iron-sulfur cluster biosynthesis, as well as to oligomerize in the presence of iron. In this dissertation metal-dependent oligomerization of fratax

Sound transmission between infinite rooms; a modal approach and fe-formulation

A full description of the entire system room-wall-room in a theoretical model for sound insulation is still today too computation intensive, implying that the higher frequencies cannot be studied. Some simplifications must thus be introduced. The simplification proposed in the present paper is to replace the rooms with wave-guides, i.e. infinity long rooms. The model then reduces to the (more or l

Changes and tendencies in European university educations in land surveying

The European university market in land surveying and land management is diversified. In many countries MSc programmes have a strong geomatic profile. In the Nordic countries the BSc and MSc engineering programmes integrate geomatics, land legislation, land policies, planning, real estate economics and property management. Such diversity is attractive for youngsters in choosing their university stu

Changing Borders : Contemporary Positions in Intermediality

A collection of 20 analyses and reflections in the research field of intermedia studies. Contemporary art and literature are marked by an increased intermedial interest. Perhaps as a result of this there is a growing amount of academic research being done on intermedial grounds, inside and outside the “proper” interart institutions. It could be argued that contemporary academic inquiries are bein
