Opis:: The rapid development of technologies and the increasingly strict international shipping regulations help to explain a significant decrease in shipping losses over decades. However, the number of accidents attributable to human errors, in which communication failures represent one third, has not been reduced proportionally. Under the Manila Amendments 2010, it became a compulsory requirement for every company to ensure that seafarers can communicate effectively. Communicative competence of seafarers has been of vital significance in modern shipping. A majority of merchant ships in international voyages are manned with multicultural and multilingual crew. It is not only the multilingual but also the intercultural character of mariners that leads to miscommunication on board. Additionally, communicative competence involves psycholinguistic, strategic and pragmatic aspects. The concept of communicative competence is relatively new in the context of maritime education and training in China and there is a dearth of research dealing with Chinese seafarers' communicative competence. Through an empirical study, this paper aims to fill in the gap by investigating the current status of Chinese seafarers' communicative proficiency from linguistic, intercultural, psycholinguistic, strategic and pragmatic perspectives to understand their strengths and weaknesses in their English communication. Based on the findings of quantitative data analysis, recommendations are finally made to improve Chinese seafarers' communicative competence.

Opis:: A novel method for feature extraction and recognition called Kernel Fuzzy Discriminant Analysis (KFDA) is proposed in this paper to deal with recognition problems, e.g., for images. The KFDA method is obtained by combining the advantages of fuzzy methods and a kernel trick. Based on the orthogonal-triangular decomposition of a matrix and Singular Value Decomposition (SVD), two different variants, KFDA/QR and KFDA/SVD, of KFDA are obtained. In the proposed method, the membership degree is incorporated into the definition of between-class and within-class scatter matrices to get fuzzy between-class and within-class scatter matrices. The membership degree is obtained by combining the measures of features of samples data. In addition, the effects of employing different measures is investigated from a pure mathematical point of view, and the t-test statistical method is used for comparing the robustness of the learning algorithm. Experimental results on ORL and FERET face databases show that KFDA/QR and KFDA/SVD are more effective and feasible than Fuzzy Discriminant Analysis (FDA) and Kernel Discriminant Analysis (KDA) in terms of the mean correct recognition rate.

Opis:: The properties of strain localization for elastic-plastic porous media with transversely isotropic elasticity under undrained conditions are investigated. Under non-associated plasticity and tri-axial stress states, the conditions for strain localization of elastic-plastic porous media are derived, in which the effects of deviation from isotropic elasticity and pore fluid compressibility are included. Based on the Mohr-Coulomb yield criterion, the influences of the deviation from isotropic elasticity and pore fluid compressibility on the direction angle of localized band initiation and the corresponding critical hardening modulus for the case of plane strain are discussed. As a result, the properties of strain localization are dependent upon the deviation from isotropic elasticity and pore fluid compressibility. The deviation from isotropic elasticity and pore fluid compressibility has significant impacts on the direction angle of localized band initiation and the corresponding critical hardening modulus.

Opis:: Twinned dendrites in Al-Zn alloy with high Zn content (40% wt.%) were successfully prepared by directional solidification. At different directional solidification rates (1000 and 1500 μm/s), microstructures and growth orientation variations of Al twinned dendrite and non-twinned dendrite were characterized. By using the inverted trapezoidal graphite sleeve at 1000 μm/s, Al twinned dendrite were formed to developed feather crystal structures in longitudinal section. Its primary and secondary twinned dendrite were grew along [110] direction. Moreover the deviation angle between [110] direction of Al twinned dendrite and the heat flow direction was about 27.15°. While not using the inverted trapezoidal graphite sleeve at 1000 and 1500 μm/s, Al dendrite was the non-twinned dendrite and the twinned dendrite was not appeared. The experimental results showed that the higher temperature gradient, a certain pulling rate and convection environment were the formation conditions of twinned dendrites.

Opis:: Estimation of tree biomass is an essential part of studies on carbon sequestration and cycling in forest ecosystem. Small trees grow in the understory and allometric development is different from that of mature trees. However, less attention has been paidto biomass estimates of small trees, especially in mixedforest where tree competition is intensive. Tree allometric equations at both branch level andat whole tree level were, thus, developed and compared for the small trees of Korean pine (Pinus koraiensis) in a mixedstandin northeastern China. At branch level, the best model for live branch biomass was one which used a combination of branch diameter, branch length, whorl position and relative branch depth. For needle biomass, the best model did not significantly improve the estimate with more variables. At whole tree level, stem diameter at breast height (DBH) was a significant determinant of biomass for different components. Tree height did not significantly improve biomass estimation at all. Tree crown variables provedto be useful for estimating all biomass components except the fine roots. The variable measuring abovegroundcompetition intensity was a significant negative determinant of biomass components except canopy biomass. Comparisons to published equations for the same species growing in Heilongjiang province in northeastern China andin central South Korea, were also presented. Both total aboveground biomass and belowground biomass in our study showed somewhat smaller values for a given diameter than the trees growing in other two places.

Opis:: As an important non-wood forest product and wood substitute, Moso bamboo grows extremely rapidly and hence acquires large quantities of nutrients from the soil. With regard to litter decomposition, N and P release in Moso bamboo forests is undoubtedly important; however, to date, no comprehensive analysis has been conducted. Here, we chose two dominant species (i.e., Cunninghamia lanceolata and Phoebe bournei), in addition to Moso bamboo, which are widely distributed in subtropical southeastern China, and created five leaf litter mixtures (PE100, PE80PB20, PE80CL20, PE50PB50 and PE50CL50) to investigate species effects on leaf litter decomposition and nutrient release (N and P) via the litterbag method. Over a one-year incubation experiment, mass loss varied significantly with litter type (P < 0.05). The litter mixtures containing the higher proportions (>80%) of Moso bamboo decomposed faster; the remaining litter compositions followed Olson's decay mode well (R2 > 0.94, P < 0.001). N and P had different patterns of release; overall, N showed great temporal variation, while P was released from the litter continually. The mixture of Moso bamboo and Phoebe bournei (PE80PB20 and PE50PB50) showed significantly faster P release compared to the other three types, but there was no significant difference in N release. Litter decomposition and P release were related to initial litter C/N ratio, C/P ratio, and/or C content, while no significant relationship between N release and initial stoichiometric ratios was found. The Moso bamboo-Phoebe bournei (i.e., bamboo-broadleaved) mixture appeared to be the best choice for nutrient return and thus productivity and maintenance of Moso bamboo in this region.

Opis:: In order to research the losses and heat of damper bars thoroughly, a multislice moving electromagnetic field-circuit coupling FE model of tubular hydro-generator and a 3D temperature field FE model of the rotor are built respectively. The factors such as rotor motion and non-linearity of the time-varying electromagnetic field, the stator slots skew, the anisotropic heat conduction of the rotor core lamination and different heat dissipation conditions on the windward and lee side of the poles are considered. Furthermore, according to the different operating conditions, different rotor structures and materials, compositive calculations about the losses and temperatures of the damper bars of a 36 MW generator are carried out, and the data are compared with the test. The results show that the computation precision is satisfied and the generator design is reasonable.

Opis:: In this experiment, seedlings as sources for shoot tips was assembled from the coconut research institute (CRI) of Chinese Academy of tropical agricultural sciences germplasm, Wenchang, Hainan, China. The shoot tips were cultured on Y3 medium to study the impact of ten concentrations of 2, 4-D and three vitamin mixtures on survival, death and development % on in vitro culture establishment stage of coconut (Cocos nucifera L.). The obtained results revealed that all 2,4-D concentrations 4,7, 75, 100, 120 and 140 mg/L + any vitamin mixture did not give any development and high concentrations of 2, 4-D increased the death %. In any case, it can be concluded that the rate of differences in survival, death and development percentages exhibited by 2, 4-D concentrations was more pronounced than the analogous ones resulted by vitamin mixtures. At any rate, utilizing of (2, 4-D at concentration 25 mg/L+ vitamin mixture 1 or 2) exhibited the greatest values of survival percentage and reduced death percentage. Just as, increased the percentages of development in in vitro culture establishment stage of coconut (Cocos nucifera L.) through seedlings shoot tip.

Opis:: To study the principle of loss and heat at the end region of large 4-poles nuclear power turbine generator, 3D transient electromagnetic field and 3D steady temperature field finite element (FE) models of the end region are established respectively. Considering the factors such as rotor motion, core non-linearity and time-varying of electromagnetic field, the anisotropic heat conductivity and different heat dissipation conditions of stator end region, a 50 Hz, 1150 MW, 4-poles nuclear power turbine generator is investigated. The loss and heat at the generator end region are calculated respectively at no-load and rated-load, and the calculation results are compared with the test data. The result shows that the calculation model is accurate and the generator design is suitable. The method is valuable for the research of loss and heat at the end region of large 4-poles nuclear power turbine generator and the improvement of the generator’s operation stability. The method has been applied successfully for the design of the larger nuclear power turbine generators.

Opis:: In the North China Plain, it is a matter of urgency to explore the feasibility of using biodegradable film to replace polyethylene film. A field experiment was conducted by covering soils with polyethylene white film, biodegradable white film, biodegradable black film, while the control remained uncovered. This study analysed the effects of using different film types on summer maize dry matter accumulation and transfer, grain yield and yield components during the 2016 and 2017 summer maize growing seasons. Results showed that, for both growing seasons, compared with non-mulching, dry matter translocation, dry matter transfer efficiency of vegetative organs and grain yield for plants following polyethylene white film and biodegradable white film treatments were always lower. However, dry matter accumulation, dry matter translocation, dry matter transfer efficiency, grain yield, and the contribution of dry matter translocation to grain yield before flowering in biodegradable black film treatments significantly increased by 21.0, 33.3, 21.4, 12.6, and 18.5%, respectively. Only the black biodegradable film could increase grain yield as determined by the 1000 kernel mass. Results indicate that black biodegradable films are a viable alternative to polyethylene film in summer maize production in the North China Plain.
