  1. 1. Exposure to inorganic arsenic in pregnancy and metabolism-nutrition interaction

    Författare :Li Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inorganic arsenic is metabolized by most mammals, including humans, via alternating reduction and oxidative methylation with S-adenosylmethionine as main methyl donor. Thus, it seems likely that it is influenced by the availability of methyl groups. LÄS MER

  3. 2. Modelling, Analysis and Design of RF Mixed-Signal Mixer for Wireless Communications

    Författare :Li Li; KTH; []
    Nyckelord :RF; INTEGRATED CIRCUITS; MIXED-SIGNAL; MIXER; WIRELESS COMMUNICATIONS; NOISE ANALYSIS; SUBSTRATE COUPLING.;

    Sammanfattning : The explosive growth of the market for wirelesscommunications is driving low cost, highly integrated designsand complex RF/analog mixed-signal integrated circuit (RF AMSIC) products. RF transceiver application is one of the mostimportant wireless applications. LÄS MER

  4. 3. Computational Studies on Homogeneous Water Oxidation Catalysts

    Författare :Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. LÄS MER

  5. 4. Conformationally Constrained Oligonucleotides for RNA Targeting

    Författare :Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conformationally constrained nucleoside; antisense oligonucleotide; RNA affinity; nuclease stability; RNase H; RNA degradation; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

    Sammanfattning : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. LÄS MER

  7. 5. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Författare :Bo Li; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PLIF; LIF; Laser-Induced Fluorescence; Rayleigh scattering; Laser Diagnostics; flame font; Combustion; Turbulence; Photofragmentation LIF; PF-LIF; Laser-induced Phosphorescence; LIP; Fysicumarkivet A:2012:Li;

    Sammanfattning : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. LÄS MER
