Innovation for ascertaining genomic islands in PAO1 and PA14 of Pseudomonas aeruginosa

Based on three distinct traits of genomic islands, a novel approach was developed to search for and determine genomic islands in special strains. Two genomic islands in Pseudomonas aeruginosa PAO1 and 7 genomic islands in Pseudomonas aeruginosa PA14 were defined with this method. Among the 9 genomic islands, 4 islands had been characterized before, while the other 5 islands were initially determined. The insert sites of 6 genomic islands are tRNA sequences, direct repeats of PA14GI-3 are relative to tRNA^Leu, and direct repeats of PA14GI-2 are at the 3＇ end of bifunctional GMP synthase/ glutamine amidotransferase. Only direct repeats of PA14GI-4 are not clear. Among the 5 newly-found genomic islands, it was supposed that PA14GI-2 is a genomic island related to Hg^2＋ uptake, PA14GI-3 is a secretory activity genomic island, PA14GI-6 is a pathogenicity island, and functions of PA14GI-1 and PA14GI-5 are not clear. Finally, the tyrosine type integrases in PAOIGI-1, PA14GI-5 and PA14GI-7 were analyzed, and their binding and restriction sites were predicted.

碳纤维表面阴离子接枝尼龙6对尼龙6等温结晶动力学的影响

利用差示扫描量热仪（DSC）研究了碳纤维（CF）表面阴离子接枝尼龙6（PA6）对CF／PA6复合材料中PA6的等温结晶动力学的影响。结果表明：PA6的等温结晶过程主要为成核作用控制；未接枝的CF对PA6结晶起异相成核作用，提高了PA6的结晶速率；表面阴离子接枝尼龙6的CF对PA6结晶仍起异相成核作用，但由于复合材料的界面相互作用提高，同时又会阻碍PA6分子链的迁移运动，导致表面阴离子接枝PA6的CF／PA6复合材料中PA6组分的结晶速度虽比纯PA6大，但比未接枝PA6的CF／尼龙6复合材料小，且结晶度也有所下降。

Adoption of precision agriculture technologies in India and in some developing countries: Scope, present status and strategies

Rapid socio-economic changes in some developing countries, including India, are creating new scopes for application of precision agriculture (PA). The implications of dramatic shifts for economic development, urbanization and energy consumption in some developing countries are immense. High-tech nature of traditional PA technologies developed in advanced countries created a real challenge for engineers to search suitable PA technologies for developing countries. It is expected that application of balanced soft and hard PA technologies based on the need of specific socio-economic condition of a country will make PA suitable for developing countries also.‘Soft’ PA depends mainly on visual observation of crop and soil and management decision based on experience and intuition, rather than on statistical and scientific analysis. ‘Hard’ PA utilizes all modern technologies such as GPS, RS, and VRT. Three components, namely,‘single PA technology’, ‘PA technology package’ (for the user to select one or combination) and ‘integrated PA technology’, have been identified as a part of adoption strategies of PA in the developing countries. Therefore, the objective of this paper is to find out the scope,the present status and the strategies for adoption of PA in India and in some developing countries. Application of PA in cash crop, plantation crop, etc. has been discussed. Application of some medium and low-tech PA tools such as chlorophyll meter and leaf colour chart in small farms has been included. This exhaustive review of the present status of PA in India and in some developing countries is expected to help to find out the adoption trend and direction of future research. Detailed strategy for the adoption of PA in India has also been proposed.

Preparation and Luminescence Properties of Nylon 6 Composite Nanofibers

The luminescent fibers have a good application prospect. The feature of this paper is that efficient luminescent nylon 6(PA6) composite nanofibers are successfully prepared by electrospinning. The luminescent PA6 composite nanofibers composed of PA6, Eu(BA)_3Phen and Tb(BAO)_3Phen(BA= P-methylbenzoic acid, BAO=P-methoxybenzoic acid, and Phen=1,10-phenanthroline). The structure and properties were characterized by scanning electron microscopy(SEM), Fourier transform infrared spectroscopy(FT-IR), fluorescence spectroscopy, and thermogravimetriy(TG) analysis. The correspondence between polymer matrix and as-prepared composite nanofibers properties has also been studied in detail. Through using hexafluoroisopropanol(HFIP) as solvent, Eu(BA)_3Phen/PA6 and Tb(BAO)_3Phen/PA6 composite nanofibers exhibit good luminescence properties. It is noted that only 5% rare earth luminescent materials are added to Tb(BAO)_3Phen/PA6 composite nanofibers, and the luminescence intensity of the as-prepared nanofibers reaches half that of the pure rare earth luminescent materials. Furthermore, uniform dispersion of pure rare earth luminescent materials in the as-prepared nanofibers gives the composite nanofibers good mechanical properties and thermal stability. These results provide an important basis for the preparation and wide application of new PA6 luminescent fibers.
