    Notizen: Abstract A contactless, compact, low-cost dilatometer based on a laser-pulse thermal-conductivity apparatus has been developed to measure the linear thermal expansion of foil materials. The two sample-edge images are projected onto the array of a charge-coupled device (CCD). Changes in sample length are determined from measurements of the corresponding displacements of the sample-edge images focused on the CCD. The dilalometer performance was tested by comparing results of measurements of the thermal expansion for pure copper with published data. The linear thermal expansion of an L-16-type foil of 20-μm thickness, which is a candidate material for thermocontrol layers (in engineering), was measured with the apparatus.

    Notizen: Abstract The growth and carotenoid production of Phaffia rhodozyma in fed-batch cultures with different feeding methods and grown at specific growth rates similar to the batch culture was compared. With constant feeding, exponential feeding, DO-stat and pH-stat fed-batch cultures of Phaffia rhodozyma, the highest biomass (17.4 g/l) and lowest carotenoid content (307 μg/g cell) of Phaffia rhodozyma was from the DO-stat fed-batch culture. The lowest biomass (14.7 g/l) and highest carotenoid content (412 μg/g cell) was from the exponential, fed-batch culture.
