    Opis:
    In South China latest Frasnian (Palmatolepis linguiformis Zone) the representatives of the order Atrypida (Brachiopoda) are most common in central Hunan Province. They are relatively rare in other parts of South China due to unfavourable ecologic conditions. Unlike most previously reported sections, including some sections in South China, the four Frasnian-Famennian (F-F) boundary sections examined here do not show any evidence for black shale. Atrypids are abundant and relatively diverse about 15 to 20 m below the F-F boundary (six species), and very rare about 1-2 m below the boundary (with only two species). It seems that the disappearance of most atrypids occurred well before the F-F boundary. Nine species (including Iowatrypa? qidongensis sp. n.), assigned to six genera, are discussed and described.

    faunal turnover
    Opis:
    The first appearance of the brachiopod Cyrtospirifer and related forms in the Late Devonian of South China significantly postdates the beginning of the Frasnian and the entry of the group in other parts of the world. Scattered data from different sections suggest that its first entry, associated with the emergence of other plicate spiriferids, such as theodossid and conispiriferid brachiopods, was late in the Middle Frasnian. At the same time, many rhynchonellids disappeared or became extinct locally in South China. This brachiopod faunal overturn near the Palmatolepis punctata–Early Pa. hassi zonal boundary is the most significant event in the Early–Middle Frasnian of South China, characterized by about a 35% loss of existing species and the flourishing of the plicate spiriferids, which was coeval with the end of a major biogeochemical perturbation recently recognized in the Pa. punctata Zone. By contrast, atrypid brachiopods do not seem to show any significant diversity change. The brachiopod faunal change was probably related to a (local?) transgressive event in South China, which also brought new pelagic faunas northwards into some intra−shelf deeper water areas, such as the Shetianqiao area in central Hunan Province. Fifteen brachiopod species are described and illustrated, which include some taxa that are first recorded or recognized in South China, e.g., the spiriferid Pyramidaspirifer, which is now known from both North America and South China. One new species, Desquamatia qiziqiaoensis, is erected.

    Opis:
    The behaviors of copper (Cu) precipitation along the radial direction of the 300 mm Czochralski grown silicon wafer have been investigated. It is found that the density of Cu precipitates decreases from the center to edge of the silicon wafer. Moreover, it is revealed that the density of grown-in oxygen precipitates also decreases along the radial direction as mentioned above. Therefore, it is apparent that the Cu precipitate density is positively correlative to the grown-in oxygen precipitate density. This is due to that the grown-in oxygen precipitates can serve as the heterogeneous nucleation centers for Cu precipitation. It is suggested that the Cu decoration in combination with preferential etching can be used to indirectly evaluate the radial distribution of grown-in oxygen precipitates in the silicon wafers.

    Opis:
    The application of the compact spinning technique with a suction groove could reduce the spinning triangle to a minimum and dramatically decrease the hairiness of ramie yarn. The change range of negative pressure was discussed when the hairiness index was reduced to a minimum for the best gathering effect. The relationship between the doffing time and hairiness index of compact yarn was studied. When the suction groove was not cleaned, the spinning times influenced the fibre number accumulated inside the suction groove. The cleaning suction groove made airflow run smoothly, and the gathering effect of fibres was basically unchanged; thus the hairiness index of yarn rarely fluctuated. For compact yarn compared with 100% 27.8 tex traditional ring-spun yarn, the 4 mm hairiness index and above decreases by more than 79.72%. The result shows that ramie compact spinning with a suction groove could gather edge fibres effectively and reduce harmful hairiness markedly.
    Zastosowanie przędzenia kompaktowego z rowkiem zasysającym pomogło zredukować trójkąt przędący i w ten sposób intensywnie zmniejszyć włochatość otrzymywanych przędz. Ustalono zakres stosowania podciśnienia dla uzyskania najlepszego efektu. Kiedy rowek zasysający nie był czyszczony, czas przędzenia wpływał na ilość włókien akumulowanych wewnątrz tego rowka. Czyszczenie rowka zasysającego powoduje, że powietrze przepływa równomiernie i efekt skupienia włókien pozostawał niezmieniony dzięki czemu indeks włochatości przędzy zmieniał się w małym stopniu. Wyniki pokazały, że kompaktowe przędzenie ramii z zastosowaniem rowka zasysającego pozwala skutecznie gromadzić skrajne włókna i redukować włochatość.

    Opis:
    The compressive properties of 3D angle-interlock woven/epoxy resin composites with various carbon nanotube (CNTs) contents were investigated under quasi-static and high strain rate loading to evaluate the compressive failure modes, which were influenced by various CNT contents and different strain rates. The results indicated that the stress strain curves were strain rate sensitive, and the compressive failure stress of composites with various CNT contents were increased with a change the strain rates and CNT contents. The compressive failure modes of 3D angle-interlock woven composites without CNT tended to be in shear deformation, delamination fibre breakage and matrix crack together, and the failure modes of 3D angle-interlock woven composites with high CNT contents presented delamination and shear deformation.
    Badano właściwości ściskające kompozytów 3D wzmacnianych tkaninami o skośnym splocie interlokowym modyfikowanych nanorurkami węglowymi. W celu wyznaczenia uszkodzeń powstałych na skutek ściskania, na które wpływa zawartość nanorurek i szybkości odkształcania, badania przeprowadzono pod obciążeniem quasi-statycznym i przy dużych szybkościach ściskania. Wyniki wykazały, że krzywe ściskania zależały od szybkości odkształcania i zawartości nanorurek. Uszkodzenia mają charakter rozwarstwienia i deformacji pod wpływem naprężeń ścinających.

    Opis:
    In this paper, crushability of foundry sand particles was studied. Three kinds of in-service silica sands in foundry enterprises selected as the study object, and foundry sand particles were subjected to mechanical load and thermal load during service were analyzed. A set of methods for simulating mechanical load and thermal load by milling and thermal-cold cycling were designed and researched, which were used to characterize the crushability for silica sand particles, the microstructure was observed by SEM. According to the user’s experience in actual application, the crushability of Sand C was the best and then Sand B, the last Sand A. The results indicated that mechanical load, thermal load and thermal-mechanical load can all be used to characterize the crushability of foundry sand particles. Microscopic appearances can qualitatively characterize the crushability of foundry sand particles to a certain extent, combining with the additions and cracks which are observed on the surface.

    Opis:
    Glucosinolates (GS) are a group of sulfur- and nitrogen-rich plant secondary metabolites that originate from amino acids and exist mainly in plants in the order Brassicales, such as Arabidopsis thaliana (Arabidopsis) and Chinese cabbage (Brassica rapa ssp. pekinensis). To date, several regulatory components responsible for GS biosynthesis have been identified in Arabidopsis. However, the functions of GS biosynthesis regulators in Chinese cabbage have not been clarified. In our current study, a putative ATR1/MYB34 orthologous gene, BrMYB34.2, was isolated from Chinese cabbage leaves. To investigate the function of this gene, we engineered Arabidopsis plants that overexpress BrMYB34.2 ectopically and phenotypic analysis was performed. Moreover, we assayed the accumulation levels of indolic GS (IGS) and aliphatic glucosinolates in transgenic plants and test the expression of key genes of IGS biosynthesis and tryptophan synthesis by Real-time quantitative PCR. And further analysed the resistance of transgenic plants in 5MT stress treatment. The results indicate that ectopic expression of the BrMYB34.2 gene in Arabidopsis was able to up-regulate the accumulation level of IGS due to the increased expression of IGS and Trp biosynthetic genes. Moreover, overexpression of BrMYB34.2 conferred Arabidopsis 5MT resistance. These results suggest that the BrMYB34.2 gene may function as one of the regulators of IGS and Trp biosynthesis in Chinese cabbage.

    Opis:
    The alvarezsauroid theropod Linhenykus monodactylus from the Upper Cretaceous of Inner Mongolia, China is the first knownmonodactyl non−avian dinosaur, providing important information on the complex patterns of manual evolution seen in alvarezsauroids. Herewe provide a detailed description of the osteology of this taxon. Linhenykus shows a number of fea− tures that are transitional between parvicursorine and non−parvicursorine alvarezsauroids, but detailed comparisons also re− veal that some characters had a more complex distribution. We also use event−based tree−fitting to perform a quantitative analysis of alvarezsauroid biogeography incorporating several recently discovered taxa. The results suggest that there is no statistical support for previous biogeographic hypotheses that favour pure vicariance or pure dispersal scenarios as explana− tions for the distributions of alvarezsauroids across SouthAmerica, NorthAmerica andAsia. Instead, statistically significant biogeographic reconstructions suggest a dominant role for sympatric (or “within area”) events, combined with a mix of vicariance, dispersal and regional extinction. At present the alvarezsauroid data set is too small to completely resolve the biogeographic history of this group: future studies will need to create larger data sets that encompass additional clades.
