in this study multivariate statistical analysis are used to characterize relationships between hydrochemical properties ofthermal and non-thermal springs. four factors for thermal waters and two for non-thermal springs were extracted basedon factor analysis. in thermal springs, the first factor showed high loading on ca, mg, na and k and this factor wasinterpreted as leaching of cations in the ...

simultaneous thermal analysis (sta) method has been applied to study decomposition reactions of ap under a flowing nitrogen atmosphere and static air. results obtained indicate that a phase transformation occurs prior to the decomposition reaction. decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. addition...

he increasing amount of heat generated by electronic devices is making devices thermal design and ways to combat heat more and more important issues to deal with. Therefore, we have developed a system able to evaluate thermally conductive materials such as conductive adhesives. The measurement technology is based on the steady-state method, and can evaluate heat transfer characteristics of moun...

The cellular fatty acid composition of Aureispira marina IAM 15389T (JCM 23197T), a gliding bacterium isolated from the coastline Thailand, was re-examined by using standard MIDI method based on alkaline hydrolysis, and two other methods. direct transesterification 5% HCl/methanol or 4 M HCl hydrolysis followed methyl esterification revealed that 2-hydroxy-15-methyl-hexadecanoic (2-OH-iso-C17:0...

Whipple's disease is a systemic disorder in which a gram-positive rod-shaped bacterium is constantly present in infected tissues. After numerous unsuccessful attempts to culture this bacterium, it was eventually characterized by 16S rRNA gene analysis to be a member of the actinomycetes. The name Tropheryma whippelii was proposed. Until now, the bacterium has only been found in infected human t...

A bacterium was isolated from the soil of dumping ground for cattle yard waste by enrichment culture containing aflatoxin B1. This bacterium was closely related to Bacillus firmus that was found to be a non-pathogenic bacterium. The minimum inhibitory concentration of aflatoxin B1 to the bacterium was found to be 80 microg ml(-1) as measured by total viable count and soluble protein content met...

Reinforcing microbial thermotolerance is a strategy to enable fermentation with flexible temperature settings and thereby to save cooling costs. Here, we report on adaptive laboratory evolution (ALE) of the amino acid-producing bacterium Corynebacterium glutamicum under thermal stress. After 65 days of serial passage of the transgenic strain GLY3, in which the glycolytic pathway is optimized fo...

The analysis of the 3D model structure of the ternary complex of recombinant formate dehydrogenase from soya Glycine max (EC 1.2.1.2., SoyFDH) with bound NAD+ and an inhibitor azide ion revealed the presence of hydrophobic Phe290 in the coenzyme-binding domain. This residue should shield the enzyme active site from solvent. On the basis of the alignment of plant FDHs sequences, Asp, Asn and Ser...

Modeling the potential spread of Xylella fastidiosa can document contingency plans in northern Europe, so far uncolonized by bacterium. Through mark–release–recapture (MRR) and flight-mill experiments, flight capacity two vectors for temperate Europe was studied: Philaenus spumarius, reported southern European vector, Aphrophora salicina, a xylem-specialist feeding on host plants X. fastidiosa....
