  1. 6. Computational Studies of Cellulose-based Materials

    Författare :Jiu Pang; Igor Zozoulenko; Alexandar Mehandzhiyski; Sergei Popov; Maria Sammalkorpi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cellulose is a remarkable organic biopolymer and sustainable raw material existing in nature. Over the past several decades, the study of cellulose materials has attracted significant attention in chemistry, physics, biomedicine, and engineering fields. LÄS MER

  3. 7. Quantitative MRI Biomarkers of Neurodegeneration in Multiple Sclerosis

    Författare :Michael Platten; Tobias Granberg; Chunliang Wang; Fredrik Piehl; Sara Shams; Mattias Vågberg; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Machine learning; Multiple sclerosis; Corpus callosum; Neurodegeneration; Medical Technology; Medicinsk teknologi;

    Sammanfattning : Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease that targets myelin in the brain and spinal cord. The corpus callosum connects the cerebral hemispheres and is composed of heavily myelinated axons. LÄS MER

  4. 8. European ecosystems on a changing planet : Integrating climate change and land-use intensity data

    Författare :Jan Hendrik Blanke; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LPJ-GUESS; land-use intensity; climate change; carbon; nitrogen; ecosystem functions; trade-offs; vegetation;

    Sammanfattning : Dynamic global vegetation models are mathematical models that provide a bottom-up description of plant communities. They explicitly model physiological and population-level processes such as growth, photosynthesis, carbon allocation, regeneration and mortality. LÄS MER

    Sammanfattning : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. LÄS MER

  7. 10. Biomechanical analyses of flywheel resistance exercise : From a space- and ground-based perspective

    Författare :Maria Sjöberg; Ola Eiken; Elena Gutierrez-Farewik; Hans E Berg; Patrik Sundblad; Loren FZ Chiu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AnyBody Modeling System; concentric; eccentric; eccentric overload; inverse dynamics; knee extensors; microgravity; musculoskeletal deconditioning; net-joint moment; AnyBody Modeling System; excentrisk; excentrisk överbelastning; invers dynamik; knäextensorer; koncentrisk; ledmoment; mikrogravitation; muskuloskeletal nedbrytning; Teknik och hälsa; Technology and Health;

    Sammanfattning : Astronauts suffer degradation of postural muscles and weight-bearing bones during long-duration spaceflight. Resistance exercise is used as a primary countermeasure against these degradations. LÄS MER
