We report the properties of a compact diode-pumped continuous-wave Nd：GdV04 laser with a linear cavity and different Nd-doped laser crystals. In a 0.2at.% Nd-doped Nd：GdVO4 laser, 1.54 W output laser power is achieved at 912nm wavelength with a slope efficiency of 24.8% at an absorbed pump power of 9.4W. With 0.3at.% Nd-doping concentration, we can obtain the either single-wavelength emission at 1064nm or 912nm or the dual-wavelength emission at 1064nm and 912nm by controlling the incident pump power. From an incident pump power of 11.6 W, the 1064nm emission between ^4fa/2 and ^4I11/2 is suppressed completely by the 912nm emission between ^4fa/2 and ^4I9/2. We obtain 670 mW output of the 912nm single-wavelength laser emission with a slope efficiency of 5.5% by taking an incident pump power of 18.4 W. Using a Nd：GdV04 laser with 0.4at.% Nd-doping concentration, we obtain either the single-wavelength emission at 1064nm or the dual-wavelength emission at both 1064nm and 912nm by increasing the incident pump power. We observe a strong competition process in the dualavelength laser.

Cabbage root fly （Delia radicum L.） control represents a major challenge in brassica production, therefore different management strategies for its control were tested in conventionally managed open field cauliflower production. Strategies included treatments with low-risk methods such as nitrogen lime, the insecticide spinosad and the Beauveria bassiana ATCC 74040-based biopesticide Naturalis. Their effects were compared with treatments based on nonformulated fungal species Metarhizium brunneum, B. bassiana, Clonostachys solani, Trichoderma atroviride, T. koningiopsis, and T. gamsii and commercial insecticides λ-cyhalothrin and thiamethoxam. Spinosad and thiamethoxam were pipetted to individual plants before transplanting; λ-cyhalothrin was sprayed after transplanting; nitrogen lime was applied at first hoeing. Nonformulated fimgi were delivered onto cauliflower plantlets＇ roots as a single pretransplantation inoculation. The cabbage root fly population dynamics exhibited a strong spatiotemporal variation. The lowest number of cabbage root fly pupae recovered from cauliflower roots in the field experiments was recorded in plants treated with spinosad （significant reduction）, followed by Naturalis and one of the tested M. brunneurn strains （nonsignificant reduction）. Significantly more pupae were counted in the nitrogen lime treatment. The field experiments showed that a single drench of cauliflower plantlets with spinosad offered consistent and enduring cabbage root fly control. Naturalis and nonformulated fungal isolates did not decrease cabbage root fly pressure significantly, apparently due to lack of statistical power. The implications of the substantial intra- and inter-annual pest pressure variation and the benefits of using single plant treatments are discussed, and recommendations for improvement of rhizosphere-competence utilizing biological control strategies provided.

Atmospheric turbulence which induced by wind shear and/or convection is non-uniform anisotropic flows of high Reynolds and Rayleigh number[1].According to the mechanism of turbulence generation,atmospheric boundary-layer stratification can be classified into neutral,unstable(convective)and stable[2].Observations show that sandstorms and wind-blown sand mostly occur under unstable stratifications from afternoon to early evening[3].As the surface absorbs the solar radiation,the surface temperature increases and vertical convection develops,which enhances the momentum exchange between the upper and lower layers and hence increases the near surface wind speed and shear stress[4].

佛教自两汉之际传入后经历了漫长的中国化过程,最终与儒学、道教并称为中国传统文化的儒释道三教。佛教思想能够在中土传播、生存、发展,有着深厚的社会思想基础,已多为前人所论。而发端于山西并流传到各地的净土信仰中土化之原因,即净土思想传入中土并为汉人接受的思想基础是汉文化中的隐净土思想。隐净土思想包含着汉文化与净土信仰在西方意义上的沟通、汉人对西方神秘世界的探索以及儒家文化中的隐净土思想等内容。

A feruloyl esterase (faE-C6) gene of 957 bp was isolated from rumen microbial metagenome, subcloned into pET32b vector, and expressed in Escherichia coli. The enzyme purified in active form, consisted of 319 amino acid residues, with a molecular weight of 43.7 based on SDS-PAGE. Homology modeling showed that the FAE contained the catalytic triad composed of Ser154-Asp263His295 and a classical Gly-X-Ser154-X-Gly nucleophile motif commonly found in esterases. The FAE-C6 was characterized using corn fiber as substrate. Its combining action with glycoside hydrolases (C, X, A) individually and in various combinations was studied with focus on the difference in thefamily:Verdana;"> effects on fa and sugar release. Glycoside hydrolases with endo-xylanase included in the enzyme mixture showed significant impact on increasing the fa yield. For the release of sugar, faE enhanced the yield in all hydrolase combinations moderately and endo-xylanase was not the key factor in the enzyme formulation.
