1 were produced in the magnetotactic bacteria Magnetospirillum gryphiswaldense [1]. Various batches of MPs were used for stoichiometric determination experiments. TEM-analyses of the MPs revealed particle diameters of 36 ± 2 nm. The concentrations of MPs in HEPES buffer (10 mM HEPES, 1 mM EDTA, pH 7.3, containing 0.04 % NaN3) were calculated using TEM-, AAS- and UV/Visspectroscopy-measurements. All oligonucleotides used in this

Uninhibited ethylene glycol hasbeen a popular heat transferfluid choice in chillers formany years because of its ini-tial low cost and excellent freeze and heat protection over a wide temperature range. It also has good heat transfer capabilities and low conductivity, not to mention that it is completely miscible with water — an inexpensive and abundant solvent. Those are the pros. There are, however, disadvantages inherent to uninhibited eth-ylene glycol, including: It is relatively easy to degrade. It promotes corrosion after it degrades. It is difficult to monitor. It absorbs water from the atmosphere. These disadvantages can lead to frequent fluid changing, which can cost users money in labor and parts. There also can be lost production costs due to shutdown and pos-sible premature failure of the system.

Since Re deposition was found to be very difficult because of its high melting and boiling points, low vapor pressure and high work function, influence of Re on the thermo-electron emission during Re deposition by TVA method was studied experimentally and theoretically. The problems were

Analytical models and finite element techniques have been employed to simulate the thermo-mechanical behaviour of overmoulded printed circuit boards. 2.

Abstract Multi-walled carbon nanotubes (MWNT) have been synthesized by chemical vapour decomposition (CVD) of acetylene over Rare Earth (RE) based AB2 (DyNi2) alloy hydride catalyst. The as-grown carbon nanotubes were purified by acid and heat treatments and characterized using powder X-ray diffraction, Scanning
