  2. 1. Mediator and its role in non-coding RNA and chromatin regualtion

    Author : Jonas O P Carlsten; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mediator; transcription; centromere; telomere; tRNA; exosome;

    Abstract : Mediator is a multiprotein complex required for the regulation of RNA Polymerase II (Pol II) transcription. Mediator transmits regulatory signals from activators and repressors to the Pol II machinery at the promoter, but the complex has also many other functions related to control of gene transcription.

  4. 2. Ellipsometric studies of SiC in the infrared, visual and ultraviolet spectral region

    Author : O. P. Alexander Lindquist; Stergios Logothetidis; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Spectroscopic ellipsometry has been used to determine the dielectric function of the most common polytypes, 3C, 4H and 6H, of SiC and also of some related materials. Measurements have been performed in the infrared, visible and ultraviolet energy region. READ MORE

  5. 3. Optical characterization of wide band gap materials by spectroscopic ellipsometry

    Author : O. P. Alexander Lindquist; Linköpings universitet; []
    Keywords : Wide Band Gap materials; ellipsometry; SiC; GaN;

    Abstract : Spectroscopic ellipsometry has been employed in the study of wide band gap materials. Ellipsometry is based on the study of changes in the polarization state of light upon reflection on a surface. READ MORE

  6. 4. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

    Author : Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

    Abstract : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. READ MORE

  7. 5. Physical fitness and overweight in Swedish youths

    Author : Örjan Ekblom; P-O Åstrand; Pekka Oja; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Övervikt hos barn; Övervikt hos ungdomar; Medicin Teknik; Medicine Technology; Adolescents; children; physical performance; fitness; trend; overweight; Sweden;

    Abstract : The aim of the present thesis was to describe the level of physical fitness and prevalence of overweight and obesity in Swedish youths, and their trends over 14 years. Additionally, the relation between fitness and overweight on the one hand and physical activity on the other was examined. READ MORE
