  • Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

    Creator:
    Pino, María-Teresa
    Abstract:
    Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

  • Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

    Creator:
    Park, Eung-Jun
    Abstract:
    Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

  • A wideband low-power continuous-time delta-sigma modulator for next generation wireless applications

    Creator:
    Chen, Xuefeng
    Abstract:
    Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ΔΣ ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT ΔΣ modulator for next generation...

  • A formative evaluation of implementation of career developement interventions in Taiwanese comprehensive high schools

    Creator:
    Chen, Meng-Yin
    Abstract:
    Taiwan has undergone significant social change, particularly in the last forty years, due to economic and industrial growth. Career development intervention is increasingly urgent in helping students face upcoming challenges. This study investigates the implementation and perceived helpfulness of career development interventions in Taiwanese comprehensive high schools. A total of...

  • Salt and polyelectrolyte affect on food colloid function : polygalacturonic acid and egg albumen case studies

    Creator:
    Chen, Chi-Shen
    Abstract:
    The primary purpose of this study was to try to (1) provide information on the chemical nature, including turbidity formation, of polygalacturonic acid in different concentrations of NaCl solution. (2) use turbidity formation characteristics to develop an assay for determining the activities polygalacturonic acid depolymerases by using a polyelectrolyte. (3)...

  • Biochemical characterization and mutational analysis of human uracil-DNA glycosylase

    Creator:
    Chen, Cheng-Yao
    Abstract:
    PCR-based codon-specific random mutagenesis and site-specific mutagenesis were performed to construct a library of 18 amino acid changes at Arg276 in the conserved leucine-loop of the core catalytic domain of human uracil-DNA glycosylase (UNG). Each Arg276 mutant was then overproduced in E. coli cells and purified to apparent homogeneity by...

  • Topological analysis, visualization, and design of vector fields on surfaces

    Creator:
    Chen, Guoning
    Abstract:
    Analysis, visualization, and design of vector fields on surfaces have a wide variety of major applications in both scientific visualization and computer graphics. On the one hand, analysis and visualization of vector fields provide critical insights to the flow data produced from simulation or experiments of various engineering processes. On...

  • Imaging fluorescent determination of energetics of chloroplast division and related matters

    Creator:
    Zheng, Ping
    Abstract:
    During exploration of imaging photosynthetic fluorimetry of Arabidopsis thaliana mutants, we discovered a novel phenomenon wherein photosynthetic efficiency (defined in Ning et al., 1995) is shown to plot in discrete groups. This exploration resulted first in the development of a spectrofluorometric method that apparently allows for in vivo observation of...

  • The function of the homeobox transcription factor Pitx2 during mammalian skeletal muscle development

    Creator:
    Shih, Hung Ping
    Abstract:
    Homeodomain transcription factors control developmental processes. They pattern body formation, specify cell lineages and switch the onset of gene regulatory cascades. Pitx2, a bicoid-related homeodomain transcription factor, is asymmetrically expressed in the left lateral plate mesoderm and mesoderm-derived tissues. Pitx2 null mice are characterized by failure of body wall closure,...

  • Low-complexity high-speed VLSI design of low-density parity-check decoders

    Creator:
    Cui, Zhiqiang
    Abstract:
    Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...
