Knowledge about fungi diversity following different planting patterns could improve our understanding of soil processes and thus help us to develop sustainable management strategies. The objective of this study was to determine the impact of different furrow-ridge mulching techniques on fungal diversity in rhizosphere soil under continuous cropping system. The investigated treatments were: flat...

BACKGROUND Most plasmids replicate only within a particular genus or family. METHODOLOGY/PRINCIPAL FINDINGS Here we describe an engineered high copy number expression vector, pBAV1K-T5, that produces varying quantities of active reporter proteins in Escherichia coli, Acinetobacter baylyi ADP1, Agrobacterium tumefaciens, (all gram-negative), Streptococcus pneumoniae, Leifsonia shinshuensis, Pe...

Nonsense mutations in structural genes appear to abort polypeptide chain synthesis at the amino acid site governed by the mutant codon. The two presently recognized types of nonsense mutant, amber and ochre, have been assigned the codons UAG and UAA, respectively. Certain bacteria harbor one or more genetic suppressors that counteract the effect of appropriate nonsense mutations in their own st...

p(ξt|ξt−1, ξt+1, β, ρ, δ, Y ) ∝ exp{−(ξt − μt) /(2σ t ) − dte tt}, where μt = (Ytδ 2 + (ξt−1 + ξt+1)ρ)/(1 + ρ ), σ t = δ /(1 + ρ), if t 6= 1 and t 6= T , and μ1 = Y1δ 2 + ξ2ρ, μT = YT δ 2 + ξT−1ρ, σ 2 1 = σ 2 T = δ . Define lt(ξt) = log p(ξt|ξt−1, ξt+1, β, ρ, δ, Y ). First, use Newton-Raphson to locate the mode x of lt and then calculate l ′′ t (x). Then draw t5 according to a t distribution wi...

The Escherichia coli outer membrane protein FhuA catalyzes the transport of ferrichrome and is the receptor of bacteriophage T5. Purified FhuA was reconstituted into liposomes. The size of the proteoliposomes and the distribution of the proteins in the vesicles were determined by freeze fracture electron microscopy. Unilamellar vesicles with a diameter larger than 200 nm were observed frequentl...

With the kind permission of Leisure and Cultural Services Department (LCSD), Energy Efficiency Office (EEO) of Electrical and Mechanical Services Department (EMSD) completed a pilot lighting project in 2002 at Kowloon Bay Indoor Games Hall (KBIGH). The new lighting system made use of the latest T5 lighting technology for illuminating the high ceiling games hall. As compared with the existing hi...
