  2. 16. Geophysical Studies Bearing on the Origin of the Arctic Basin

    Author : Nina Lebedeva-Ivanova; Christopher Juhlin; David Gee; Ruth Jackson; Uppsala universitet; []
    Keywords : refraction seismic; reflection seismic; crustal structure; Arctic Ocean; Amerasia Basin.; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : Deep troughs and ridges of the Arctic Basin are some of the least known features of the Earth's crust. Some of the ridges, eg. Chukchi and Nordwind, are connected directly to the continental shelves and are certainly submarine promontories of the latter. READ MORE

  4. 17. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Author : Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

  5. 18. Spin transfer torques and spin dynamics in point contacts and spin-flop tunnel junctions

    Author : Alexander Konovalenko; Vladislav Korenivski; David W. Abraham; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin dynamics; spin transfer torques; point contacts; magnetization dynamics; Physics; Fysik;

    Abstract : The first part of this thesis is an experimental study of the spin-dependent transport in magnetic point contacts. Nano-contacts are produced micromechanically, by bringing a sharpened non-magnetic (N) tip into contact with a ferromagnetic (F) film. READ MORE

  6. 19. Uncovering the genetics underlying host-parasite interactions during Plasmodium falciparum malaria transmission

    Author : Mubasher Mohammed; Johan Ankarklev; David Serre; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malaria; Plasmodium falciparum; Genomics; single-cell RNA-seq; Parasite cell fate; Anopheles gambiae; ApiAP2 transcription factors; driver genes; computational biology; molekylär biovetenskap; Molecular Bioscience;

    Abstract : In eukaryotes, cellular differentiation is often orchestrated by programmed arrays of activation and repression of genes underlying the specific phenotypes of cell-types. To complete its life cycle, the single-celled Apicomplexan parasite Plasmodium falciparum, the most deadly of the human malaria parasites, must repeatedly differentiate and convert into unique cell types that can exploit niches within their human and mosquito hosts.

  7. 20. Inflammatory Signaling Across the Blood-Brain Barrier and the Generation of Fever

    Author : Anna Eskilsson; David Engblom; Annika Thorsell; Göran Engberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Fever is a cardinal sign of inflammation and is evolutionary conserved. Fever is known to be beneficial during acute inflammation, but over time and if very high it can be detrimental. READ MORE
