  1. 1. Neurotensin and cortical arousal : an in vitro study

    Författare :Lovisa Case; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The information processing associated with wakefulness occurs during what is commonly referred to as a cortical desynchronized state. In contrast, deep sleep is accompanied by slow, synchronized electrical activity, perhaps best exemplified by the slow (... LÄS MER

  3. 2. Tracking single molecules in uncharted territory : A single-molecule method to study kinetics in live bacteria

    Författare :Javier Aguirre Rivera; Magnus Johansson; Dmitri N. Ermolenko; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-molecule; protein synthesis; fluorescence microscopy; antibiotics; aminoglycosides; macrolides; apramycin; gentamicin; paromomycin; S13; translation; bacteria; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : The synthesis of proteins, also known as translation, is a fundamental process in every living organism. The steps in the translation of genetic information to functional proteins have been meticulously studied, mostly using in vitro techniques, yielding a detailed model of their mechanisms. LÄS MER

  4. 3. Studies of acoustic waves, noise and charge pumping using single-electron devices

    Författare :Martin Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-electron pump; single-electron transistor; surface acoustic wave; single-electron devices; charge pumping; TLF; SINIS turnstile; electrometer; two-level fluctuator; single-photon detector; noise; SAW; SET;

    Sammanfattning : This thesis covers a range of experiments on single-electron devices, electrical circuits that utilize the discreetness of the electron charge. The Single-Electron Transistor (SET) is of special importance among these, being the most sensitive electrometer demonstrated, and sufficiently mature to serve as a building block in sensors and detectors for physical phenomena that can be transformed into charge signals.

  5. 4. Statistical modeling and design in forestry : The case of single tree models

    Författare :Leakemariam Berhe; Göran Arnoldsson; Göran Broström; Dieter Rasch; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest data; Covariance structures; Nonlinear mixed effects models; Tree taper models; Ds-optimal design; Replication-free design.; Statistics; Statistik;

    Sammanfattning : Forest quantification methods have evolved from a simple graphical approach to complex regression models with stochastic structural components. Currently, mixed effects models methodology is receiving attention in the forestry literature. LÄS MER

  7. 5. DREAM: A Method for Understanding the Causation of Single-Vehicle Crashes

    Författare :Jesper Sandin; Chalmers tekniska högskola; []
    Nyckelord :driver error; accident model; contributory factors; causation; single-vehicle crashes; case study; pre-crash; accident analysis;

    Sammanfattning : When conducting in-depth causation studies, it is essential that the analysis method can both define and classify contributing factors and be able to analyse how these factors may interact to produce a critical event. These issues are highly influenced by the underlying theory, e.g. the accident model. LÄS MER
