  1. 1. Changes in the transcriptome and metabolome during the initiation of growth cessation in hybrid aspens

    Författare :Daniel Hoffman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : At 9 550 years of age, Old Rasmus, a Norway spruce (Picea abies), located in the Dalarna province in Sweden is recognized as the oldest surviving tree in the world. Old Rasmus exemplifies a robust capacity to survive in changing conditions, making trees a unique and fascinating subject for study. LÄS MER

  3. 2. Computational modeling of complex flow : Doctoral thesis at Chalmers University of Technology

    Författare :Johan Hoffman; Claes Johnson; Ragnar Winter; Chalmers; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we consider the following aspects of computational modeling of complex flows: (i) subgrid modeling, (ii) stability, (iii) a posteriori error estimation, and (iv) computational platform. We develop a framework for adaptivity and error control for multiscale problems, in particular for turbulent flow, based on a posteriori error estimates. LÄS MER

  4. 3. Mechanisms of opiate tolerance and dependence in the rat

    Författare :Orsolya Hoffman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Drug addiction is a complex phenomenon with various biological, psychological and social causes and consequences, which belongs to the major problems of today's society. Opiates have been used and misused for thousand of years and addiction to them develops both in humans and in animals. LÄS MER

  5. 4. Dispersal of ticks and their microorganisms by African-Western Palaearctic migratory birds

    Författare :Tove Hoffman; Björn Olsen; Åke Lundkvist; Kenneth Nilsson; Johan Normark; Uppsala universitet; []
    Nyckelord :African-Western Palaearctic; migratory birds; Ixodidae; Hyalomma rufipes; Ixodes; Alkhurma hemorrhagic fever virus; Anaplasma phagocytophilum; Francisella; Midichloria; Rickettsia aeschlimannii; PCR; microfluidic qPCR; metagenomics; Biologi; Biology;

    Sammanfattning : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.
