    Sammanfattning : Currently, more than half of all Swedish single-family houses have an installed heat pump and more heat is supplied by heat pumps in Sweden than in any other nation. Despite the enormous impact of heat pumps on the Swedish energy system, the transition towards their use has gone relatively unnoticed. LÄS MER

  3. 12. Production and Characterization of ZrN and PuN Materials for Nuclear Fuel Applications

    Författare :Marcus Hedberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal gelation; Carbothermal reduction; Zirconium Nitride; Plutonium Nitride; Nuclear fuel;

    Sammanfattning : At the heart of a nuclear reactor resides its fuel. The chemical composition of the nuclear fuel affects the performance of several key properties important for the overall operation and safety performance of the reactor. LÄS MER

  4. 13. Imperial Freedmen and Roman Society : A study on the social standing of imperial freedmen as expressed in literary and epigraphic sources in the early Roman Empire

    Författare :Lisa Hagelin; Gerd Haverling; Gunhild Vidén; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; imperial freedmen; emperor; status; social history; early empire; Pliny; Tacitus; Seneca; Latin epigraphy; Rome; Latin language; Latin; Latin; Latin;

    Sammanfattning : This study discusses the imperial freedmen’s standing in Roman society as it is expressed in literary and epigraphic sources. It has often been assumed that the traditional elite had a general negative attitude towards this group, and previous scholars have interpreted the social standing of the imperial freedmen very differently due to the discrepancy between the legal status and the social status of these freedmen.

  5. 14. Den gemensamma utvecklingen

    Författare :Mats Fridlund; KTH; []
    Nyckelord :;

    Sammanfattning : This study analyzes a Swedish development pair (utvecklingspar), a close, long-term collaborationbetween a private industrial company and a state customer onseveral development projects for new technologies. The specificsubject is the formation of a development pair around electricpower technologies between the State power utility the RoyalBoard of Waterfalls (Vattenfall) and the electrotechnical company Asea.

  7. 15. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Författare :Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Phylogenetics; Mitochondrial origin and Evolution; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.
