Soil samples at 0-10 cm in depth were collected periodically at paired fields in Corvallis, Oregon, USA to compare differences in soil microbial and faunal populations between organic and conventional agroecosystems. Results showed that the organic soil ecosystem had a significantly higher (P erage number or biomass of soil bacteria; densities of flagellates, amoebae of protozoa; some nematodes, such as microbivorous and predaceous nematodes and plant-parasitic nematodes; as well as Collembola. Greater numbers of Rhabditida (such as Rhabditis spp.), were present in the organic soil ecosystem while Panagrolaimus spp. were predominant in the conventional soil ecosystem. The omnivores and predators of Acarina in the Mesostigmata (such as Digamasellidae and Laelapid), and Prostigmata (such as Alicorhaiidae and Rhagidiidae), were also more abundant in the organic soil ecosystem. However, fungivorous Prostigmata (such as Terpnacaridae and Nanorchestidae) and Astigmata (such as Acarida) were significantly higher (P e conventional soil ecosystem, which supported the finding that total fungal biomass was greater in the conventional soil ecosystem. Seansonal variations of the population depended mostly on soil moisture condition and food web relationship. The population declined from May to October for both agroecosystems. However, higher diversities and densities of soil biota survived occurred in the organic soil ecosystem in the dry season.

Grass carp（Ctenopharyngodon idella） is one of the most important species in *** ethane（DBDPe） is a brominated flame retardant that has been used widely in industry, and has been observed to accumulate in the tissues of fish from South China. evidence has shown that DBDPe is toxic to aquatic animals, but the molecular response has been unclear. MicroRNAs（miRNAs） are small noncoding and negative regulatory RNAs that are 20–24 nucleotides in length, which are involved in a wide range of biological processes. We took advantage of deep-sequencing techniques to accurately and comprehensively profile the kidney mi RNA expression of grass carp after 8 weeks of oral exposure to DBDPe. After mapping sequencing data to the genome and expressed Sequence Tags（eSTs） of grass carp, we identified 493 miRNAs in the sequenced grass carp samples, which included 51 new miRNAs. The results indicated that 5 miRNAs were significantly down-regulated and 36 miRNAs were significantly up-regulated（FDR 〈 0.001,1.5-fold change） after DBDPe exposure. Real-time quantitative PCR（RT-qPCR） was performed on 4 miRNAs from the two samples, and the sequencing and RT-qPCR data were consistent. This study provides the first comprehensive identification of grass carp miRNAs, and the first expression analysis of grass carp miRNAs following DBDPe *** results indicated that miRNAs have potential for use as biomarkers.

The zincblende ternary alloys Tl_xGa_（1-x） As（0 〈 x 〈 1） are studied by numerical analysis based on the plane wave pseudopotential method within the density functional theory and the local density approximation. To model the alloys,16-atom supercells with the 2 × 2 × 2 dimensions are used and the dependency of the lattice parameter, bulk modulus,electronic structure, energy band gap, and optical bowing on the concentration x are analyzed. The results indicate that the ternary Tl_xGa_（1-x） As alloys have an average band gap bowing parameter of 4.48 eV for semiconductor alloys and 2.412 eV for semimetals. It is found that the band gap bowing strongly depends on composition and alloying a small Tl content with GaAs produces important modifications in the band structures of the alloys.

A steady increase in consumer demands, and severe constraints from both a somewhat damaged environment and newly installed government policies, require today's product design and development to be faster and more efficient than ever before, yet utilizing even fewer resources. New holistic approaches, such as total product life cycle modeling which embraces all aspects of a product's life cycle, are current attempts to solve these problems. Within the field of product design and modeling, feature technology has proved to be one very promising solution component. Owing to the tremendous increase in information technology, to transfer from low level data processing towards knowledge modeling and information processing is about to bring a change in almost every computerized application. From this viewpoint, current problems of both feature frameworks and feature systems are analyzed in respect to static and dynamic consistency breakdowns. The analysis ranges from early stages of designing (feature) concepts to final system implementation and application. Por the first time, an integrated view is given oil approaches, solutions and practical experience, with feature concepts and structures, providing both a feature framework and its implementation with sufficient system architecture and computational power to master a fair number of known consistency breakdowns, while providing for robust contexts for feature semantics and integrated models. Within today's heavy use of information technology these are pre-requisites if the full potential of feature technology is to be successfully translated into practice.

＜正＞ Thin films of various vanadium oxides, including the phase transition materials vanadium dioxide and vanadium pentoxide, have been prepared by reactive ion-beam sputtering. Results show that film microstructure is the dominant factor affecting the optical properties of these coatings. Changes in optical reflectance and transmittance data, which accompany the structural changes, are presented and discussed.

This paper examines cellular and molecular mechanisms that may underpin the purported effects of five herbal supplements in the context of athlete immune function. Ginseng and echinacea are used frequently by athletes, whereas astragalus and elderberry are used infrequently and pequi is just emerging as a possible supplement. In vivo studies of these products on athlete immune function have yielded heterogeneous results, likely due to experimental design differences. Ginseng, echinacea, elderberry, and pequi are considered asterids sensu lato. Ginseng appears to exert strongest effects on components of adaptive immunity, in particular maintaining Thl/Th2 balance of CD4^4 T cells and their downstream effects, via its ginsenosides, flavonoids, and polysaccharides. echinacea alkamides, caffeic acid derivatives, and polysacchardies may target both innate and adaptive immunity, though perhaps the former more consistently. elderberry harbors anthocyanins and lectins which may modulate innate immunity. Data on pequi is limited but suggests that carotenoids, phenols, and fatty acids may alter circulating leukocyte populations. More phylogenetically distant, astragalus is a rosid sensu lato and may influence the innate immune system through flavonoids, polysaccharides, and saponins. Supplements generally demonstrate no effects on physiologic parameters such as lactate, oxygen dynamics, or athletic performance. Bioavailability studies indicate that purported bioactive molecules of these supplements may reach circulation in low but therapeutically-relevant quantities. Difficulties in cross- comparisons due to study design differences, coupled with an overall dearth of research on the topic, currently hamper any formal conclusions regarding the efficacy of these supplements as immunoregulators for athletes.
