  1. 16. Regeneration in periodontal and endosseous implant treatment

    Författare :Lisa Mayfield; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Odontology; guided tissue regeneration; Pressure sensitive periodontal probe; intraosseous defects; guided bone regeneration; EDTA root surface conditioning; bioabsorbable membrane; stomatology; Odontologi;

    Sammanfattning : In a series of clinical studies regenerative procedures for periodontal disease treatment were evaluated. A reproducibility study of probing measurements using a manual periodontal probe and 3 pressure-sensitive probes showed that measurements obtained using the manual probe were the most repeatable.

  3. 17. Selective Catalytic Reduction of NOx: Deactivation and Regeneration Studies and Kinetic Modelling of Deactivation

    Författare :Raziyeh Khodayari; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; modelling; sulphation; regeneration; deactivation; bio fuel; WO3; V2O5; TiO2; catalyst; NOx; SCR; Kemiteknik och kemisk teknologi; Chemistry; Kemi;

    Sammanfattning : Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. LÄS MER

  4. 18. Astrocytes, reactive gliosis and CNS regeneration

    Författare :Ulrika Wilhelmsson; Göteborgs universitet; []
    Nyckelord :CNS regeneration; astrocytes; reactive gliosis; intermediate filaments;

    Sammanfattning : The regenerative capacity in the adult central nervous system (CNS) is very limited, and the glial cells have been implicated in the inhibition of CNS regeneration. In essentially all CNS pathologies, astrocytes are activated and this process is known as reactive gliosis. LÄS MER

  5. 19. Brain Regeneration - in vitro and in vivo studies of exercise-related effects on brain plasticity

    Författare :Cecilia Bull; Göteborgs universitet; []
    Nyckelord :brain; neural progenitor cells; stem cells; hippocampus; corpus collosum; rat; mouse; regeneration; neurogenesis; oligodendrogenesis; irradiation; exercise;

    Sammanfattning : Neural stem and progenitor cells in the germinal regions of the adult brain, such as the hippocampus, are of great interest, because they provide the possibility for enhanced brain plasticity or can contribute to endogenous cell replacement after injury or disease. Voluntary exercise was recently shown to robustly induce cellular and structural plasticity, thereby contributing to overall brain health. LÄS MER

  7. 20. Magnetic Refrigeration for Near Room-Temperature Applications

    Författare :Behzad A Monfared; Björn Palm; Joachim Claesson; Andrew Rowe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic Refrigeration; Magnetic; Cooling; Magnetocaloric; Life Cycle Assessment; Modeling; Simulation; Optimization; Regeneration; Active Magnetic Regeneration; Bonded Regenerator; Heat Switch; Thermal Diode; Peltier; Solid-State; Prototype; Magnetisk Kylteknik; Magnetisk; Kylning; Magnetokalorisk; Livscykela-nalys; Modellering; Simulering; Optimering; Regenerering; Aktiv Mag-netisk Regenerering; Bunden Regenerator; Värmebrytare; Termodiod; Peltier; Solid-State; Prototyp; Energy Technology; Energiteknik;

    Sammanfattning : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. LÄS MER
