    Opis:
    A series of temperature-sensitive polyurethanes (TSPUs) with polytetrahydrofuran glycol (PTMG), poly(ethylene glycol) (PEG) and maleic anhydride modified castor oil (MCO) as soft segments were prepared in this paper. The morphology of the temperature-sensitive polyurethane films was characterised by SEM, DSC and WAXD. SEM studies were also carried out to investigate the surface structure of coated and uncoated fabrics. The water vapour permeability of the coated and uncoated fabrics were measured as well. The results showed that a nonporous TSPU layer was formed on the coated fabric surface. The tailor -made TSPUs had one to three soft segment crystal melting point temperatures, with the lower peak temperature Tpm1 belonging to the soft segment PTMG and the higher peak temperature Tpm2 to the hydropilic soft segment PEG2000. The water vapour permeability of TSPUs coated fabrics increased with an increase in PEG2000 concentration and PEG molecular weight, but decreased with an increase in the hard segment content, and triggered around the soft segment crystal melting point temperature of TSPUs.
    W pracy otrzymano termowrażliwe poliuretany (TSPU) z glikolu politetrahydrofuranowego (PTMG), glikolu polietylenowego (PEG) i bezwodnika maleinowego zmodyfikowanego olejem rycynowym (MCO). Za pomocą SEM, DSC i WAXD zbadano morfologię termowrażliwych folii poliuretanowych. Przeprowadzono również badania SEM w celu zbadania struktury powierzchni powleczonych i niepowleczonych tkanin. Zmierzono także przepuszczalność pary wodnej powleczonych i niepowleczonych tkanin.

    Opis:
    This paper presents 2 musculoskeletal disorders questionnaire surveys in 10 different Chinese occupational groups. Data collected from 1,603 workers using a modified Nordic musculoskeletal disorders symptom questionnaire showed that the 12-month prevalence of musculoskeletal disorders, particularly in the low back and shoulder-neck regions, was high at many Chinese workplaces. Significant differences existed between occupational groups. Assembly workers usually had higher neck-shoulder complaints compared to workers in most other occupations. However, the nature of assembly seemed also to influence the prevalence rate. Workers at a cassette recorder and a TV set assembly plant appeared to have more neck complaints compared with a group of thermos flask assemblers.

    Opis:
    In this paper, we introduce four new classes of open sets in general Euclidean space RN. It is shown that every such class of open sets is compact under the Hausdorff distance. The result is applied to a shape optimization problem of p-Laplacian equation. The existence of the optimal solution is presented.

    Opis:
    Application of 1-butyl-3-metyhlimidazaolium hexafl uorophosphate ([C4mim][PF6 ]), in the extraction of rubidium and cesium from brine solutions using 1,4,7,10,13,16-hexaoxacyclooctadecane (18C6) as extractant was investigated. Parameters that affect the extraction including pH of aqueous phase, equilibration time, dosage of the ionic liquid, phase ratio, concentration of 18C6 were studied. Under the optimal conditions, the single extraction effi ciency of rubidium ions and cesium ions were up 84.11% and 94.99%, respectively. The stripping of alkali metal ions from the loaded organic phase with different stripping agents and concentrations were also investigated. The initial value of the K/Cs and K/Rb ratios were 93.0 and 104.3, respectively, which have dropped 91.21% and 88.01%, respectively, after the extraction and stripping experiments. It was taken a big step in the separation and enrichment of cesium (rubidium) ion and potassium ion. The extraction mechanism was revealed most likely to be a cation exchange mode in this system.

    Opis:
    Speaker‘s emotional states are recognized from speech signal with Additive white Gaussian noise (AWGN). The influence of white noise on a typical emotion recogniztion system is studied. The emotion classifier is implemented with Gaussian mixture model (GMM). A Chinese speech emotion database is used for training and testing, which includes nine emotion classes (e.g. happiness, sadness, anger, surprise, fear, anxiety, hesitation, confidence and neutral state). Two speech enhancement algorithms are introduced for improved emotion classification. In the experiments, the Gaussian mixture model is trained on the clean speech data, while tested under AWGN with various signal to noise ratios (SNRs). The emotion class model and the dimension space model are both adopted for the evaluation of the emotion recognition system. Regarding the emotion class model, the nine emotion classes are classified. Considering the dimension space model, the arousal dimension and the valence dimension are classified into positive regions or negative regions. The experimental results show that the speech enhancement algorithms constantly improve the performance of our emotion recognition system under various SNRs, and the positive emotions are more likely to be miss-classified as negative emotions under white noise environment.

    Opis:
    An efficient and accurate method to test Escherichia coli (E. coli) adhesion to intestinal epithelial cells will contribute to the study of bacterial pathogenesis and the function of genes that encode receptors related to adhesion. This study used the quantitative real-time polymerase chain reaction (qPCR) method. qPCR primers were designed from the PILIN gene of E. coli F18ab, F18ac, and K88ac, and the pig β-ACTIN gene. Total deoxyribonucleic acid (DNA) from E. coli and intestinal epithelial cells (IPEC-J2 cells) were used as templates for qPCR. The 2−ΔΔCt formula was used to calculate the relative number of bacteria in cultures of different areas. We found that the relative numbers of F18ab, F18ac, and K88ac that adhered to IPEC-J2 cells did not differ significantly in 6-, 12-, and 24-well culture plates. This finding indicated that there was no relationship between the relative adhesion number of E. coli and the area of cells, so the method of qPCR could accurately test the relative number of E. coli. This study provided a convenient and reliable testing method for experiments involving E. coli adhesion, and also provided innovative ideas for similar detection methods.
