Online product reviews have become an important opinion resource which many researchers pay their attention to. In this paper, a novel method of opinion mining is proposed and evaluated by a collection of real online product reviews. A hierarchical fuzzy domain sentiment ontology-FDSO has been introduced by this approach, which defines a space of product features and corresponding opinions, thus makes it possible for a product to be classified and scored by commonly accepted features. Therefore enhance the user experience to search a product and compare it with other products feature by feature. The evaluation is based on the Chinese product reviews collected from 360buy.com. The experimental results show that our approach is able to automatically identify the polarity for a large of sentiment expressions. © 2013 ACADEMY PUBLISHER.

Microsatellite markers previously developed for red clover (Trifolium pratense L.) were used in crossamplification tests of eight other Trifolium species. Of the 20 SSR loci tested, 9 (47.37 %) had positive results and were found to be transferable to all eight species examined. The number of alleles detected at each locus ranged from 4 to 12, with an average of 7.2 in T. tumens Steven ex M. Bieb., 5.8 in T. resupinatum L., 5.1 in T. fragiferum L., 4.5 in T. tomentosum L., 3.4 in T. bullatum Boiss. & Hausskn. ex Boiss., 3.2 in T. clusii Godr. & Gren., 2.7 in T. spumosum L. and 2.1 in T. physodes Stev. ex M. B. This study has shown that SSR markers developed for red clover effectively amplify DNA from other species and this approach may be applicable for the analysis of intra- and interspecific genetic diversity of target Trifolium species. © Shiraz University 2016.

Soil is part of the Earth's life support system, but how should we convey the value of this and of soil as a resource? Consideration of the ecosystem services and natural capital of soils offers a framework going beyond performance indicators of soil health and quality, and recognizes the broad value that soil contributes to human wellbeing. This approach provides links and synergies between soil science and other disciplines such as ecology, hydrology, and economics, recognizing the importance of soils alongside other natural resources in sustaining the functioning of the Earth system. We articulate why an ecosystems approach is important for soil science in the context of natural capital, ecosystem services, and soil change. Soil change is defined as change on anthropogenic time scales and is an important way of conveying dynamic changes occurring in soils that are relevant to current political decision-making time scales. We identify four important areas of research: (i) framework development; (ii) quantifying the soil resource, stocks, fluxes, transformations, and identi- fying indicators; (iii) valuing the soil resource for its ecosystem services; and (iv) developing decision-support tools. Furthermore, we propose contributions that soil science can make to address these research challenges. © Soil Science Society of America, All rights reserved.

Strains 1.15.5T, 2.27.5, 5.24.4 and 6.14.5 were isolated from a solar saltern. They have flattened, rod-shaped cells and are aerobic, extremely halophilic members of the domain Archaea and family Halobacteriaceae. Cells stained Gram-negative and grew optimally in media around neutral pH and containing 20-24% (w/v) (strains 1.15.5T and 2.27.5) or 22-24% (w/v) (5.24.4 and 6.14.5) salts. Mg2+ was not required. The DNA G+C contents of these isolates were all close to 58 mol%, and DNA-DNA cross-hybridization showed a mean relatedness of 77 %. Their 16S rRNA gene sequences differed by no more than 1.6% from each other. Phylogenetic tree reconstructions with other recognized members of the Halobacteriaceae indicated that they formed a distinct clade, with the closest relative being Halorubrum saccharovorum (86.6-87.6% 16S rRNA gene sequence similarity to the type strain). The only major polar lipid of all four isolates was the sulfated diglycosyl diether lipid S-DGD-1. By phase-contrast microscopy, the long, flattened cells of these strains often displayed a 'wing-like' shape. The phenotypic and phylogenetic data support the placement of these isolates into a novel species in a new genus within the Halobacteriaceae, for which we propose the name Halonotius pteroides gen. nov., sp. nov. The type strain of Halonotius pteroides is 1.15.5T (=JCM 14355T =CECT 7525T 5DSM 18729T), with the additional reference strains 2.27.5 (=JCM 14356 =DSM 18671), 5.24.4 (=JCM 14357 =DSM 18673) and 6.14.5 (=JCM 14358 =DSM 18692). © 2010 IUMS.

Two isolates of non-alkaliphilic, extremely halophilic archaea, with very similar characteristics, were recovered from a marine solar saltern crystallizer. Cells were pleomorphic, motile and Gramstain-negative and grew on a limited range of carbon sources, with pyruvate being the best substrate. Optimum growth occurred at 18-20% (w/v) NaCl, pH 6.0-8.5 and 37-40 °C. Both isolates possessed typical archaeal lipids, and their 16S rRNA gene sequences were 99.8% identical. Phylogenetic tree reconstructions indicated that they were most closely related to the haloalkaliphile Natronomonas pharaonis (97.5% similarity to the type strain), but the different phenotypic properties and low DNA-DNA hybridization values between Nmn. pharaonis DSM 2160T and the two isolates suggested that they represent a novel species within the genus Natronomonas. The name Natronomonas moolapensis sp. nov. is proposed for these isolates, with the type strain being 8.8.11T (=JCM 14361T =CECT 7526T =DSM 18674T). An emended description of the genus Natronomonas is also provided. © 2010 IUMS.
