  2. 1. Condition-Based Maintenance: Selection and Improvement of a Cost-Effective Vibration-Based Maintenance Policy for Rolling element Bearings

    Author : Basim Al-Najjar; Sherwin David; Bo Bergman; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; a cost-effective vibration-based maintenance policy.; Integrated maintenance; Condition monitoring and control; Total Time on Test-plots; Vibration monitoring; effectiveness and accuracy; Failure causes and mechanisms; Maintenance quality; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Commercial and industrial economics; Industriell ekonomi; Maintenance Technology; Terotechnology;

    Abstract : Modern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. READ MORE

  4. 2. Machinery diagnostic techniques for maintenance optimization

    Author : Juhamatti Saari; Jan Lundberg; Kalevi Huhtala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : One of the future challenges of machinery diagnostics and prognosticsis to prepare for the Internet of Things (IoT), where it is possible to change and improve existing approaches drastically. An intensifying application of the IoT will increase the use of embedded sensors and, therefore, create a demand for diagnostic tools where manual workis minimized and is mainly handled by smart algorithms.

  5. 3. Biochemical studies of mitochondrial DNA maintenance and topology

    Author : Direnis Erdinc; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mtDNA maintenance; topoisomerase; replication;

    Abstract : Mitochondria are crucial organelles in eukaryotic cells that produce the majority of adenosine trisphosphate used by cells as an energy currency to drive metabolic processes. Due to the endosymbiotic origin of mitochondria, they have their own genetic material, a small circular double-stranded molecule (mtDNA) of 16. READ MORE

  6. 4. Maintenance of neuronal identity and function

    Author : Konstantinos Toskas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neurons in the CNS acquire specific characteristics throughout development and maintain them for the entire lifespan. Instructive regulation of the transcription machinery ensures the acquisition of identity by spatiotemporal patterns of transcription factor expression. READ MORE

  7. 5. Studies of molecular mechanisms of telomere maintenance in Naumovozyma castellii

    Author : Ahu Karademir Andersson; Molekylär cellbiologi; []
    Keywords : YEAST; Saccharomyces castellii; Naumovozyma castellii; Processvity; Telomerase; Telomere; ALT; Strain engineering;

    Abstract : Telomeres are special DNA-protein structures that protect ends of chromosomes from being recognized as double-strand breaks. Telomeres consist of tandemly repeated units of TG-rich DNA and associate with telomere-specific proteins. READ MORE
