  2. 1. Dissecting the roles of viral T-antigens in Merkel cell carcinoma

    Author : Jiwei Gao; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Merkel cell carcinoma (MCC) is a rare but aggressive form of skin malignancy with increasing incidence. Merkel cell polyomavirus (MCPyV) is associated with ~80% of MCCs, and a minority is caused by ultra-violet (UV)-induced DNA damage. The MCPyV T-antigens are major drivers for MCC oncogenesis.

  4. 2. Characteristics of streamer discharges in air and along insulating surfaces

    Author : Lan Gao; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : Power quality is dependent on the dielectric properties of the insulators used throughout the power generation and power transmission utilities. Knowledge of the pre-discharge stage associated with the electrical breakdown across outdoor insulators is essential if one is to improve the performance of these insulators under various electrical and environmentalconditions.

  5. 3. Biotope and biodiversity mapping in forest and urban green space : methodological review and developments

    Author : Tian Gao; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Forests play an important role in providing ecosystem services that support the ecological integrity of an area and also supply social benefits for humans. Many of the essential ecological and social benefits derived from forest are underpinned by its biodiversity. READ MORE

  6. 4. First Principles Studies of Carbon Based Molecular Materials

    Author : Bin Gao; Yi Luo; Piero Decleva; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; first principles simulations; carbon based molecular materials; X-ray spectroscopies; Theoretical chemistry; Teoretisk kemi;

    Abstract : The aim of this thesis was to investigate carbon based molecular materials at first principles levels. Special attention has been paid to simulations of X-ray spectroscopies, including near edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron, and X-ray emission spectroscopy, which can provide detailed information about core, occupied and unoccupied molecular orbitals of the systems under investigation.

  7. 5. Advanced Functional Materials for Intermediate-Temperature Ceramic Fuel Cells

    Author : Zhan Gao; Bill Bergman; Mogens Mogensen; Ceramics; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Low to intermediate-temperature solid oxide fuel cell (SOFC, 500 oC-700 oC) based on doped ceria (DCO) electrolyte has attracted much attention during the last decade. However, DCO suffers from electronic conduction caused byreduction of Ce (IV) to Ce (III) at high temperatures and low oxygen partial pressures and has a high grain-boundary resistivity. READ MORE
