    Sammanfattning : Water is an essential compoment of every living orgamism and forms a major part of the human body. Regulated water transport is crucial for proper cell functioning and body homeostasis. LÄS MER

  3. 12. Topsar och cellmembran : Kroppens näringsupptag i undervisning och elevtexter på mellanstadiet

    Författare :Alma Jahic Pettersson; Carl-Johan A. Rundgren; Lena Tibell; Ragnhild Löfgren; Nicklas Gericke; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social semiotic; Metaphors; Everyday expressions; Systemic functional grammar; Organizational levels; Biology; Chemistry; Multimodality; Socialsemiotik; Metaforer; Vardagsuttryck; Systemisk funktionell grammatik; Organisationsnivåer; Biologi; Kemi; Multimodalitet;

    Sammanfattning : I avhandlingen studeras mellanstadieelevers meningsskapande kring näringsupptag. Avhandlingens artiklar baseras på två datainsamlingar. I den första studeras skriftliga svar på ett nationellt prov i biologi. I den andra studeras klassrumsundervisning i två skolor med en animation om näringsupptag som kontext. LÄS MER

  4. 13. Planar-Goubau-line components for terahertz applications

    Författare :Juan Cabello Sánchez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; planar Goubau line; Through-Reflect-Line TRL calibration; stopband filter; on-wafer measurements; vector network analyzers VNA ; silicon membrane; power divider; Impedance-matched load; terahertz spectroscopy; microfluidic channels;

    Sammanfattning : Terahertz-wave technology has a broad range of applications, including radio astronomy, telecommunications, security, medical applications, pharmaceutical quality control, and biological sensing. However, the sources, detectors, and components are less efficient at this frequency band due to parasitic effects and increased total losses, which hinder the performance of terahertz systems.

  5. 14. Membrane rafts and its GPI anchored complement inhibitors regulate insulin secretion

    Författare :Vini Nagaraj; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Membrane rafts; basal insulin secretion; regulated insulin secretion; CD59; CD55; SNARE proteins; insulin; pancreatic beta cells.;

    Sammanfattning : Type 2 diabetic patients usually exhibit an abnormal lipid profile. One such lipid that is constantly elevated in T2D is cholesterol. At the cellular level, cholesterol aids in tight packing of sphingolipids in certain regions of the plasma membrane and these specialized regions are termed ‘membrane rafts’, which act as signalling hubs.

  7. 15. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

    Författare :Indriati Pfeiffer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

    Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.
