  1. 1. Biochemical conversion of biomass : hydrothermal pretreatment, by-product formation, conditioning, enzymatic saccharification, and fermentability

    Författare :Dimitrios Ilanidis; Leif J. Jönsson; Carlos Martin; Björn Alriksson; Eulogio Castro; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic biomass; hydrothermal pretreatment; enzymatic digestibility; ethanolic fermentation; microbial inhibitors; conditioning;

    Sammanfattning : Lignocellulosic residues have great potential as feedstocks for production of bio-based chemicals and fuels. One of the main routes is biochemical conversion, which typically includes pretreatment, enzymatic saccharification, microbial fermentation of sugars, and valorization of hydrolysis lignin. LÄS MER

  3. 2. Creep, deformation and moisture redistribution during air convective wood drying and conditioning : air convective wood drying and conditioning

    Författare :Tom Morén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Air convective wood drying is associated with a considerable risk for damage to the timber, especially checking and warping. This thesis contains an analysis of creep and deformation during wood drying related to stress development and susceptibility of checking. Also heat and mass transfer problems in the wood drying process are considered. LÄS MER

  4. 3. Cerebellar pathways and mechanisms in classical conditioning

    Författare :Pär Svensson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; Climbing Fibers; Conditioned Response; Mossy Fibers; Ferret; Eyeblink; Cerebellum; Classical Conditioning; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : It has been suggested that the cerebellar mossy fibre afferents transmit the conditioned stimulus (CS) information to the cerebellum. Several studies are consistent with this suggestion but alternative explanations have not been excluded. LÄS MER

  5. 4. Imaging fear and anxiety in the human brain : Positron emission tomographic studies

    Författare :Håkan Fischer; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; fear; anxiety; panic; conditioning; human; brain; neuroimaging; positron emissiontomography; PET; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Fear and anxiety are central human experiences. However, the relation between aspects of these aversive emotional states and brain function have previously been studied mostly in animals. LÄS MER

  7. 5. Cerebellar Control of Classical Conditioning

    Författare :Magnus Ivarsson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Associative module; Bilateral; Orbicularis oculi muscle; Inferior olive; Purkinje cell; Eyeblink; Conditioned response; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology;

    Sammanfattning : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.
