    Notes: Alternanthera philoxeroides (Mart.) Grisb is an invasive weed that is widespread in a variety of habitats around the world. It was introduced into China in the 1930s, and today occurs in 20 provinces. The level and pattern of genetic diversity of 193 individuals from 11 land-grown A. philoxeroides populations from South China were determined using 81 intersimple sequence repeat markers. Mean Nei's gene diversity (HE) was 0.0203 ± 0.008, and total diversity (HT) was 0.0286, indicating that genetic diversity in A. philoxeroides in South China is very low. There was a greater proportion of diversity within populations than among (GST =  0.292) populations. Gene flow (Nm) among populations was 0.607. These results are in accordance with the assumption that populations in South China are genetically depauperate because of the short introduction history and the partially clonal propagation of this weed.

    QTL analysis of cooked rice grain elongation, volume expansion, and water absorption using a recombinant inbred population (2005)

    Notes: The traits of elongation, volume expansion, and water absorption are very important in determining the quality of cooked rice grains. In this study, quantitative trait loci (QTL) analysis of these traits was performed using a recombinant inbred population derived from a cross between two indica cultivars, ‘Zhenshan 97’ and ‘Minghui 63,’ which are the parents of the most widely grown hybrid rice in China. Using a linkage map based on 221 molecular marker loci covering a total of 1796 cM, a total of 33 QTLs were identified for the nine traits tested. QTLs were detected on chromosomes 1–3, 5–9, and 11, respectively. The QTLs identified included three for cooked rice grain length elongation (chromosomes 2, 6, and 11), six for width expansion (chromosomes 1-3, 6, 9, and 11) and two for water absorption (chromosomes 2 and 6). Interestingly, a single QTL located near the wx gene on chromosome 6 seemed to influence all the traits tested for the cooked rice quality.

    Genetic diversity of Pueraria lobata (kudzu) and closely related taxa as revealed by inter-simple sequence repeat analysis (2005)
    Oxford, UK : Blackwell Science Ltd
    Weed research 45 (2005), S. 0 
    Details

    Notes: Kudzu (Pueraria lobata) is a noxious weed infesting some areas of the USA. Knowledge of its genetic variation in both native and invasive areas can lead to effective biological control measures. Inter-simple sequence repeat (ISSR) variations were studied in P. lobata and its four closely related congeneric species (P. edulis, P. montana, P. phaseoloides and P. thomsoni). ISSR results allowed a clear separation of these five species. For P. lobata, 108 plants from China and USA were analysed. The samples from the US were genetically closer to Chinese P. lobata populations than to other congeneric populations. High genetic differentiation was found for P. lobata, P. montana and P. thomsoni in Chinese samples. High genetic diversity and low population differentiation was found in P. lobata samples of the US. This supports the hypothesis of multiple introductions into the USA from different sources in Japan or China, followed by subsequent gene exchange and recombination.

    Genetic structure of the invasive Chromolaena odorata in China (2004)
    Oxford, UK : Blackwell Science Ltd

    Details

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Chromolaena odorata is one of the world's worst tropical weeds, and it can be found in Guangdong, Guangxi, Hainan and Yunnan provinces in China. Genetic variation of 27 C. odorata populations sampled from across its invasive range in China was investigated using inter-simple sequence repeats (ISSR) analysis. All populations exhibited low levels of genetic variation. On average, 2.35% of the ISSR loci were polymorphic, total genetic diversity (HT) was 0.0406 and Shannon's information index (Hsp) was 0.0623. High genetic identities (I) between populations (0.9687 ± 0.01204) indicated low genetic differentiation. A frequent founder effect was interpreted as the main cause of the genetic structure observed in C. odorata.

    Magnetic properties of FeSi-SiO2 granular films : The 6th joint magnetism and magnetic materials (MMM)-intermag conference (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 6490-6492

    ISSN: 1089-7550

    Topics: Physics
    Notes: The ferromagnetic resonance (FMR) spectra and coercivities of FeSi-SiO2 granular films have been measured over a wide range of FeSi volume fractions (fv). The films were prepared using the ion-beam sputtering technique and transmission electron microscopy showed that the FeSi alloy granules are embedded in a matrix of SiO2. An enhanced coercivity (Hc), as high as 329 Oe at room temperature, is observed. For some samples, there are several resonance peaks in the FMR spectra, which include one major peak and several minor peaks. The major and minor peaks correspond to the usual uniform mode and spin-wave respectively. In our experiments, the field separations between the major and the minor peaks show a complex fashion. Our results are discussed in comparison with some theoretical models.

    Notes: Abstract  By introducing an hydroxyl group and a lipophilic branch into the middle of lipophilic head of emulsifier 12-oxy-9-octadecenoic acid, a new emulsifier was synthesized and applied in microemulsion polymerization. When the emulsifier content in the microemulsion was kept to about 12%, the highest monomer content in microemulsion could achieve 35% for BA, 20% for St and MMA. The microemulsion with high monomer content remained clear after polymerization, and the average diameters of polymer particles were 38.9 nm for St microemulsion, 47.4 nm for BA, and 50.7 nm for MMA.

    Notes: Abstract A novel device for measurements of the normal and directional total emissivity of solid surfaces in the range 300–600 K is described. The measurements were performed using the radiation comparison method. A novel black-body radiation source is used as a standard. The detection system consists of a pyroelectric head, a preamplifier, a chopper, and a matching lock-in amplifier with analog recorder ourput. The device is simple and well suited for routine measurements. Comparison of our results with those of previous investigations shows a good agreement.

    ISSN: 1572-9567
    Keywords: calorific intensity ; hot probe ; organ or tissue of a living body ; specific heat ; thermal conductivity ; thermal diffusivity

    Topics: Physics
    Notes: Abstract A new method was developed to determine simultaneously the thermal conductivity, thermal diffusivity, specific heat, and calorific intensity of the organ or tissue of a living body either in vivo or in vitro with a thin hot probe. By using the method, the thermophysical properties and calorific intensities of a human palm and in vivo liver and a kidney, heart, brain, and foreleg and hindleg muscles of an anesthetized canine were measured. It is concluded that there are no significant differences in the thermophysical properties of organ or tissue of a living body either in vivo or in vitro. The measured thermophysical properties are in good agreement with those reported in the literature.
