    Author : Jing Xiao; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business groups; New technology-based firms NTBFs ; Acquisitions; Entrepreneurial dynamics; Acquisition effects; Survival; Firm growth; Business cycle; Multinational enterprises MNEs ; Longitudinal data; Discrete-time duration models; Competition risks models; Fixed effects model; Inverse-probability-of-treatment weights IPTW ; Sweden;

    Abstract : The aim of this thesis is to explore the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. NTBFs are argued to be one important type of entrepreneurial firms that contribute to technology change, knowledge spillovers, and economic growth. READ MORE

  4. 2. Modulation of acetylcholine release by serotonergic 5-HT1A and 5-HT1B receptors : a microdialysis study in the awake rat

    Author : Xiao Jing Hu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microdialysis; Acetylcholine; Serotonin; 5-HT1A receptor; 5-HT1B receptor; Frontal cortex; Ventral hippocampus;

    Abstract : The aim of the thesis was to investigate the effects of the 5-HT1A receptor antagonist robalzotan (NAD-299) and the 5-HT1B receptor antagonist NAS-181 ((R)-(+)-2-(3-morpholinomethyl-2Hchromen-8-yl) oxymethyl-morpholine methanesulfonate) on cholinergic, glutamatergic and GABAergic neurotransmission in the rat brain in vivo. The extracellular levels of acetylcholine (ACh), glutamate (Glu) and GABA were monitored by microdialysis in the frontal cortex (FC) and ventral hippocampus (VHipp) in separate groups of awake rats.

  5. 3. Bioelectrochemical Applications of Reactions Catalyzed by Immobilized Enzymes

    Author : Xiao-Jing Tang; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acetate Kinase.; NAD NADH recycling; Enzyme Electrodes; Enzyme reactors; Enzyme Immobilization; Electrochemical detection; Flow Injection Analysis; Analytical chemistry; Analytisk kemi;

    Abstract : The sensitivity of biosensors can be increased substantially by incorporation in a substrate recycling scheme. Based on the amplification of NAD+/NADH by the recycling reaction catalyzed by glycerol dehydrogenase (GDH) and diaphorase, NAD+/NADH can be determined amperometrically with around 1000 times higher sensitivity than for the substrate sensing mode.
