  1. 1. Rate and Accuracy of Bacterial Protein Synthesis

    Författare :Magnus Johansson; Måns Ehrenberg; Jon Lorsch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein synthesis; ribosome; peptidyl transfer; rate-accuracy trade-off; kinetics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : High levels of accuracy in transcription, aminoacylation of tRNA, and mRNA translation are essential for all life forms. However, high accuracy also necessarily means large energy dissipation and slow kinetics. Therefore, in vivo there is a fine tuned balance between rate and accuracy of key chemical reactions.

  4. 3. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

    Författare :Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

    Sammanfattning : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. LÄS MER

  5. 4. Accuracy of protein synthesis and its tuning by mRNA modifications

    Författare :Gabriele Indrisiunaite; Måns Ehrenberg; Suparna Sanyal; Jaanus Remme; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Protein synthesis; Translation; Accuracy; Release factor; Termination; mRNA modifications; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The ribosome is a large macromolecular complex that synthesizes all proteins in the cell in all kingdoms of life. Proteins perform many vital functions, ranging from catalysis of biochemical reactions to muscle movement. It is essential for cells and organisms that proteins are synthesized rapidly and accurately. LÄS MER

  7. 5. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

    Författare :Lars Ekman; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

    Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER
