Sphingomonas spp. of alpha-proteobacteria often play a role in assisting the development of microfloral communities under adverse soil conditions. Using a Frateuria sp. as an indicator for bacterial growth assay, we investigated the bacterial growth-promoting factor in the culture fluids of Sphingomonas sp. EC-K085. This factor was successfully isolated and identified as linear (R,R,R,R)-3-hydr...

A highly sensitive and rapid method for the determination of substance P (SP) and streptolysin O (SLO) in human serum is described. The assay is based on enriching the analyte by agglutination/precipitation of immuno-liposomes and enhancing the fluorescence intensity by gramicidin A channels. A mixture of the immuno-liposomes encapsulating a pH-sensitive fluorescence dye BCECF, gramicidin A and...

-The present paper deals with a modification on the selection of linear systematic sample of odd size. Consequently the proposed method is called modified linear systematic sampling. The performances of the modified linear systematic sampling are assessed with that of simple random sampling and linear systematic sampling for certain hypothetical populations. As a result, it is observed that the...

Progressive Pruning (PP) is used in the Monte-Carlo go playing program Indigo. For each candidate move, PP launches random games starting with this move. PP gathers statistics on moves, and it prunes moves statistically inferior to the best one [5]. This papers yields two new pruning techniques: Miai Pruning (MP) and Set Pruning (SP). In MP the second move of the random games is selected at ran...

Fluorescence in situ hybridization was modified by using genomic DNAs as probes to detect wide cross somatic hybrids. The A genome was labelled and visualized as red signal while the B and C genomes were visualized as blue and green signals, respectively. This technique could distinguishly identify the hybrid SP I line with whole full sets of 6 genomes and the hybrid SP II line with some lost c...

The PSP model [1], a generalized Surface-Potential (SP) model, has been chosen to be an industry standard for the next generation, 60nm, technology. In order to include quantum effects within surface potential models we use asymptotic analysis techniques [2], [3] applied to the the Density-Gradient equations [4]. Our quantum modified surface potential (SP) results from the ability to obtain a f...

The ability of Boophilus microplus strains to be susceptible (-) or resistant (+) to amidines (Am), synthetic pyrethroids (SP), and/or organo-phosphates (OP) (or acaricide profiles) was investigated in 217 southeastern Mexican cattle ranches (located in the states of Yucatán, Quintana Roo, and Tabasco). Three questions were asked: (1) whether acaricide profiles varied at random and, if not, whi...

in wireless sensor networks (wsns), localization algorithms could be range-based or range-free. the approximate point in triangle (apit) is a range-free approach. we propose modification of the apit algorithm and refer as modified-apit. we select suitable triangles with appropriate distance between anchors to reduce pit test errors (edge effect and non-uniform placement of neighbours) in apit a...
