Molecular mapping of new blast resistance genes is important for developing resistant rice cultivars using marker-assisted selection. In this study, 259 recombinant inbred lines (RILs) were developed from a cross between Nipponbare and 93-11, and were used to construct a 1165.8-cM linkage map with 131 polymorphic simple sequence repeat (SSR) markers. Four major quantitative trait loci (QTLs) for resistance to six isolates of Magnaporthe oryzae were identified: qPi93-1, qPi93-2, qPi93-3, and qPiN-1. For the three genes identified in 93-11, qPi93-1 is linked with SSR marker RM116 on the short arm of chromosome 11 and explains 33% of the phenotypic variation in resistance to isolate CHE86. qPi93-2 is linked with SSR marker RM224 on the long arm of chromosome 11 and accounts for 31% and 25% of the phenotypic variation in resistance to isolates 162-8B and ARB50, respectively. qPi93-3 is linked with SSR marker RM7102 on chromosome 12 and explains 16%, 53%, and 28% of the phenotypic variation in resistance to isolates CHE86, ARB52, and ARB94, respectively. QTL qPiN-1 from Nipponbare is associated with SSR marker RM302 on chromosome 1 and accounts for 34% of the phenotypic variation in resistance to isolate PO6-6. These new genes can be used to develop new varieties with blast resistance via marker-aided selection and to explore the molecular mechanism of rice blast resistance.

Polymer-assisted deposition is a chemical solution route to high quality thin films. In this process, the polymer controls the viscosity and binds metal ions, resulting in a homogeneous distribution of metal precursors in the solution and the formation of crack-free and uniform films after thermal treatment. We review our recent effort to epitaxially grow metal-nitride thin films, such as hexagonal GaN, cubic TiN, AlN, NbN, and VN, mixed-nitride Ti1-xAlxN, ternary nitrides tetragonal SrTiN2, BaZrN2, and BaHfN2, hexagonal FeMoN2, and nanocomposite TiN-BaZrN2.

Mechanical property prediction methods for composites are very important as theoretical tools for engineeringstructural design. To more accurately capture the transverse mechanical properties of composites, a multiscale analysismethod is developed in this paper. The multiscale analysis method includes three scales: (1) At the microscale, a microscopiccohesive model based on atomic potential energy is established for the interface; (2) At the mesoscale, a unit cell model isestablished for the fibre, matrix and interface; and (3) At the macroscale, the homogenization method, failure criteria anddamage degradation models are used for predicting the transverse mechanical properties. Subsequently, the transversemechanical properties and the damage evolution process are simulated with the multiscale analysis method. A comparisonbetween the simulations and experiments shows that the maximum error of the predicted transverse modulus and transversestrength is -4.45 % and -12.05 %, respectively. Finally, the effects of the interfacial strength on the macroscopic transversemechanical properties and the damage onset are analysed. The following conclusions are drawn from the simulation results:(1) The interfacial strength has a more significant effect on the transverse strength and ultimate strain than on the transversemodulus; (2) Decreasing the interfacial strength has a greater effect on the transverse modulus, strength and ultimate strainthan increasing the interfacial strength; and (3) The interfacial strength can change the damage onset.

The carbon fiber/epoxy matrix interface plays an important role in the behavior and damage onset of unidirectionalfiber reinforced epoxy matrix composites and accurate modeling techniques are needed to study the effects of this complexregion on the composite response. In this work, a microscopic cohesive zone model (MCZM) based on atomic potentialenergy is established for the interface. A multiscale analysis method is proposed for predicting the transverse mechanicalproperties of unidirectional fiber composites: (1) At the microscale, MCZM is established for the interface; (2) At themesoscale, a unit cell model is established for the fiber, matrix and interface; and (3) At the macroscale, the homogenizationmethod, failure criteria and damage degradation models are used for predicting the transverse mechanical properties. Subsequently, the transverse mechanical properties and the damage evolution process are simulated with the multiscaleanalysis method. A comparison between the simulations and experiments shows that: (1) The maximum errors of thepredicted transverse modulus and transverse strength are -4.45 % and -1.28 %, respectively; and (2) MCZM can reflect thenonlinearity of epoxy matrix composite materials. Moreover, the effects of the interfacial strength on the macroscopictransverse mechanical properties and the damage onset are analysed. The simulation results show that: (1) The interfacialstrength has a more significant effect on the transverse strength and ultimate strain than on the transverse modulus; (2)Decreasing the interfacial strength has a greater effect on the transverse modulus, strength and ultimate strain than increasingthe interfacial strength; and (3) The interfacial strength can change the damage onset.

Brevibacillus brevis GZDF3 is a gram-positive, plant growth-promoting rhizosphere bacterium (PGPR) isolated from the rhizosphere soil of Pinellia ternata (an important herb in traditional Chinese medicine). The GZDF3 strain produces certain active compounds, such as siderophores, which are the final metabolite products of non-ribosomal peptide synthetase (NRPS) and independent non-ribosomal peptide synthetase (NIS) activity. With the present study, we attempted to investigate the siderophore production characteristics and conditions of Bacillus sp. GZDF3. The antibacterial activity of the siderophores on pathogenic fungi was also investigated. Optimal conditions for the synthesis of siderophores were determined by single factor method, using sucrose 15 g/l, asparagine 2 g/l, 32°C, and 48 h. The optimized sucrose asparagine medium significantly increased the production of siderophores, from 27.09% to 54.99%. Moreover, the effects of different kinds of metal ions on siderophore production were explored here. We found that Fe3+ and Cu2+ significantly inhibited the synthesis of siderophores. The preliminary separation and purification of siderophores by immobilized-metal affinity chromatography (IMAC) provides strong antibacterial activity against Candida albicans. The synergistic effect of siderophores and amphotericin B was also demonstrated. Our results have shown that the GZDF3 strain could produce a large amount of siderophores with strong antagonistic activity, which is helpful in the development of new biological control agents.

印度半岛是世界上宗教历史最悠久的区域,宗教贯穿了从古印度到英属印度,再到后来印巴分治的历史发展过程。第二次世界大战结束之后,随着世界民族解放运动热潮澎湃,再加上英属印度境内的印度教徒和穆斯林之间的对立不断激化,宗主国英国推出了《蒙巴顿方案》来承认穆斯林建立独立政权的权力,这最终导致印度于1950年正式构建了民族国家,紧接着1956年巴基斯坦构建了共和国。宗教因素对印巴两国的民族国家构建,以及对建国后的从政治经济等各个领域都起到了重要的作用。本文在比较分析印度教对印度建国的作用和伊斯兰教对巴基斯坦建国的作用后,论证了宗教在印巴两国民族构建作用方面的相同点和差异性。本文发现了宗教是印巴两国构建民族国家的思想基础,但在凝聚力方面存在明显差异;宗教思想不同程度的影响了两国的国家政策和施政纲领;宗教还不同程度的强化了两国各民族对于国家的认同感。 The Indian peninsula is the region with the longest religious history in the world. Religion runs through the historical development process from ancient India to British India, and then to the partition between India and Pakistan. After the second world war, with the booming of national movement for emancipation, coupled with British India suffering from intensified confrontation between hindus and muslims, suzerain Britain introduced the ‘Mountbatten Plan’ to admit Muslim to establish a separated regime, which ultimately led to the construction of India nation-state in 1950, and the formation of Pakistan followed in 1956. Religious factors played an important role in the nation-state construction, as well as in various fields including politics, economy and so on after the establishment of the two countries. After a comparative analysis of the Hinduism’s role in the founding of India and that of Islam in the founding of Pakistan, this paper demonstrated the similarities and differences of religions’ roles in India and Pakistan. As a result, this paper found that religions were the ideological basis for both India and Pakistan to build a nation-state, but there are obvious differences in cohesion. Religious thoughts have influenced the national policies and administrative programs of the two countries in different degrees. Religions also more or less have strengthened the sense of national identity of each ethnic group in the two countries.
