It has been suggested that the eastern Asian temperate flora have responded to Quaternary climatic changes in a different way compared with temperate plants in Europe and Northern America. However, knowledge about their phylogeographic structure and evolutionary history is still limited. In this study we investigated mitochondrial DNA variation in 17 populations of Pinus kwangtungensis, a five-needled pine inhabiting in isolated mountains of southern China and northern Vietnam. A total of ten mitochondrial haplotypes (mitotypes) were characterized by the polymorphisms of two fragments (cox-1-2 and nad7 intron1), and total genetic diversity was high (hT = 0.847). The construction of phylogenetic relationships of the ten mitotypes detected three major, well-distinct clades, largely corresponding to four population groups identified by SAMOVA analysis. SAMOVA also indicated that most genetic variance should be attributed to among-group differentiation (FCT = 0.868), consistent with the substantial genetic structure found within P. kwangtungensis (GST = 0.751). The genetic distances of P. kwangtungensis weakly but significantly correlated with geographical distances (R = 0.228, P = 0.03), revealing a pattern of isolation-by-distance. Demographic analysis did not detect any bottleneck events in the recent history of P. kwangtungensis. These results clearly suggested that there were three major refugia for this montane temperate conifer during warm stages (along with other minor refugia), and that the species would have tracked Quaternary climatic changes by expanding to nearby lowlands in the glacial periods, and by retreating to mountaintops (the refugia) during interglacial warmer stages, experiencing fragmentation and isolation among refugia. © Springer-Verlag 2009.

A new monomer, bis[4-(p-phenoxybenzoyl)-1,2-benzenedioyl]-N,N,N′, N′-4,4′-diaminodiphenyl sulfone (BPBDADPS), was prepared by the Friedel-Crafts reaction of bis(4-chloroformyl-1,2-benzenedioyl)-N,N,N′, N′-4,4′-diaminodiphenyl sulfone (BCBDADPS) with diphenyl ether (DPE). Novel poly(aryl ether ketone)s containing sulfone and imide linkages in the main chains (PAEKSI) were synthesized by electrophilic solution polycondensation of terephthaloyl chloride (TPC) with a mixture of DPE and BPBDADPS under mild conditions. The copolymers obtained were characterized by different physico-chemical techniques. The copolymers with 10-30 mol% BPBDADPS are semi-crystalline and had remarkably increased Tg values over commercially available PEEK and PEKK due to the incorporation of sulfone and imide linkages in the main chains. The copolymers III and IV with 20-30 mol% BPBDADPS had not only high Tg values of 180-187 °C, but also moderate Tm values of 338-341 °C, having good potential for the melt processing. The copolymers III and IV had tensile strengths of 100.7-104.2 MPa, Young's moduli of 2.31-2.44 GPa, and elongations at break of 12.2-14.7% and exhibited high thermal stability and good resistance to organic solvents. © The Author(s) 2011.

The animation gradually started to become a sunrise industry, the combination of ceramics and animation is a fusion of classical culture and modern culture try. Market situation determines the potters to move closer to the animation industry, the derivative products of animation ceramic is inevitable. Positioning in the market, combined with the feasibility of the above we have done some relevant analysis, drawing that the animation ceramics market prospect is broad, and have identified several possible design directions. © (2013) Trans Tech Publications, Switzerland.

In the course of development, the ceramic art blends to science and technology culture, which forms a distinctive ceramic art and design performance practices. The literary and rhetorical device were applied to the design of ceramic art, making the ceramic works be full of personality, enhancing works infectious and conveys the mood of the effect. In this paper, it focuses on the design elements in the ceramic works, exploring the metaphor, a symbol, and narrative, exaggerated analogy rhetorical devices such as the use of ceramic art design, in order to create a suitable ceramic works. © (2013) Trans Tech Publications, Switzerland.

With the development of large grid, distributed, heterogeneous complex power network, the power grid management is more and more complex and its safety operation is more important. In order to effective control of power systems in normal operating conditions within the shortest possible time, the relay signal must be accurately passed to the communication terminal by the transmission channel. At present, optical fiber protection channel is widely used in many parts in China. It also has some problems, such as leakage of immature technology, lack of synchronous optical transmission signal protection performance indicators. In this paper, the basic content of relay protection is described, the application of optical fiber communication technology, as well as the problems exposed in the practical application in the signal transmission channel is introduced, the development prospect of new technologies and materials for optical fiber communication technology is analyzed. © 2013 Springer-Verlag London.

Given the present condition and the existing problem in the course of Web animation, the major point of teaching will be emphasized by the invocation of courses, the ability of creative thought will be cultivated by the means of from static to dynamic, and the college Web animation course will be innovated by means of display of inverse movement in order to form the scientific structure and methods of professional course. Meanwhile, teaching of course is sophisticated and systematical, so it requires continuous coordination and corporation among every phrase of teaching instead of simple mode and means for the differences between majors and courses. © 2013 Springer-Verlag Berlin Heidelberg.

The aesthetic is a need, the humanistic psychologist Maslow made his famous Theory of Demand. In his view, physiological, safety, respect, aesthetic, self-actualization level from junior to senior development needs. Form of beauty, art and design epitomizes the spirit of this advanced form of aesthetic needs. Pottery as a traditional media people becoming more concerned about environmental consciousness and spiritual level, but also both involved in the environmental space in the case of modern consciousness, showing it is a form of the emerging field of environmental art, pottery design consistent with human on the environmental aesthetic needs of the development of results, its aesthetic value cannot be ignored. An art form as a visual language, environment pottery body language has a unique aesthetic value and characteristics, and continue to join in today's visual culture under the influence of cultural concerns, its aesthetic characteristics in terms of interpretation of the visual language also has the image era semantic features. An area designed as a public environmental art, Environmental Ceramic aesthetic environment and the environment of people closely related to the artistic life, the concept of the art of living also make work pay more attention to the reality of the workplace awareness and survival, the manifestation of the spiritual needs Therefore aesthetic inject a greater angle. The visual aesthetic activity comes from the sensory response, but limited to the spiritual feeling, which mobilized human emotion, imagination, understanding mental function. These aesthetic mental activities are affected by different environment, different populations, different era with different cultural backgrounds and Cultural Complex of the impact and role. © (2014) Trans Tech Publications, Switzerland.

Sports bra is designed for female breast of athletes in moderate to severe competition, which can provide some protection. The comfort level of sports bra is particularly important for female athletes. In the fierce sports competition, if the female athletes were in the absence of external protection, her breast may be subjected to serious injury, especially the plump breast. So comfortable sports bras will certainly become the popular selling products in the clothing market. In this paper, we analyzed the protection function of female breast from the bodice fabric and other aspects by using three-dimensional dynamic simulation, which was based on the innovation mechanism of biomedical theory. © 2013 Springer-Verlag.
