  1. 1. Evolutionary Mechanisms Shaping Bacterial Translation Termination

    Författare :Shreya Pundir; Suparna Sanyal; Martin Ott; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Protein; Release Factor; Translation; Termination; Stop codon; Evolution; Mutation; Kinetics; Cryo-EM; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : Translation termination in bacteria involves precise reading of stop codons (UAA, UAG, UGA) and coordinated peptidyl-tRNA hydrolysis by the class-I release factors (RFs) on the ribosome (70S). This thesis investigates the evolutionary and post-translational modification mechanisms of these RFs and the concurrent effect on bacterial translation termination. LÄS MER

  3. 2. Termination and Cost Analysis : Complexity and Precision Issues

    Författare :Abu Naser Masud; Samir Genaim; Germán Puebla; Technical University of Madrid; []
    Nyckelord :;

    Sammanfattning : The research in this thesis is related to static cost and termination analysis.Cost analysis aims at estimating the amount of resources that a given programconsumes during the execution, and termination analysis aims at proving thatthe execution of a given program will eventually terminate.

  4. 3. Unraveling the regulatory mechanisms of pupal diapause termination

    Författare :Philip Süess; Philipp Lehmann; Christian Wegener; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diapause; diapause termination; prothoracicotropic hormone; ecdysone; thermal performance; Functional Zoomorphology; funktionell zoomorfologi;

    Sammanfattning : Diapause is an essential part of many insect’s life cycle and is a developmental halt induced by environmental cues in advance of deteriorating conditions. Insects typically enter diapause to avoid unfavorable environmental conditions like low temperatures, poor food quality and the absence of conspecifics. LÄS MER

  5. 4. Patterns of Repetition and Change in a Psychoanalytically Informed Therapeutic Environment for Severely Disturbed Patients

    Författare :Andrzej Werbart; Per Vaglum; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychotherapy research; psychosis; personality disorders; therapeutic community; ward atmosphere; therapeutic alliance; concordance; separation; working through; termination; outcome.; Psychology; Psykologi;

    Sammanfattning : Factors in the environment and therapeutic relationship which facilitate, as well as those which obstruct the process of psychic change were investigated in patients with psychoses or severe personality disorders, starting from a preliminary theoretical model for psychoanalytically oriented treatment. Ten patients consecutively admitted to a Swedish therapeutic community, Bikupan, and who completed the treatment, as well as their 9 therapists were studied in detail during, and up to five years after the treatment.

  7. 5. Parameterized Systems : Generalizing and Simplifying Automatic Verification

    Författare :Ahmed Rezine; Parosh Aziz Abdulla; Kedar Namjoshi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parameterized systems; Automatic verification; Approximation; Regular model checking; Safety; Termination; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Sammanfattning : In this thesis we propose general and simple methods for automatic verification of parameterized systems. These are systems consisting of an arbitrary number of identical processes or components. The number of processes defines the size of the system. LÄS MER
