    Abstract The distribution of the sequences of ceruloplasmin mRNA in different fractions of heterogeneous nuclear RNA from rat liver was studied using cDNA transcripts of highly purified mRNA as hybridization probe. The content of ceruloplasmin mRNA sequences in poly(A)-containing and poly(A)-free subfractions of heterogeneous nuclear RNA is respectively 1 and 27 molecules per a hepatocyte. Heterogeneous nuclear RNA carrying the sequences of ceruloplasmin mRNA sedimented in sucrose gradients containing formamide, as a broad zone around the 56S peak. Denaturing electrophoresis followed by the transfer of RNA onto diabenzyloxymethyl paper and hybridization with [32P]-cDNA revealed multiple high molecular weight fractions of ceruloplasmin pre=mRNA (9.0, 6.6, 2.2 and 1.6 megadaltons) in the non-adenylated fraction of nuclear RNA and a single 1.1–1.2 megadalton zone in poly(A)-containing nuclear RNA, the latter being equal in size to the mature ceruloplasmin mRNA from liver polysomes.

    Notes:
    Abstract In near-calm conditions it is difficult to make direct measurements of atmospheric advection reliably and cheaply, particularly at many points over a large area. An alternative indirect method is examined using time-series measurements of atmospheric temperature (or any other convenient conserved field variable) at points on a spatial grid. System identification methodology is applied to analyze atmospheric temperature data obtained in such near-calm conditions during an experiment with a low-flying helicopter. A three-parameter numerical model of atmospheric advection has been identified in the temperature data, the advection parameters being an eddy diffusion coefficient and horizontal components of the wind velocity. It has been demonstrated by analysis of all the assumptions, and using simulated data, that in this case the standard least-square procedure can be applied to recover sensible parameter estimates, even though the model is of the error-in-variables type and parameters appear to change abruptly at certain moments of time (but by a reasonably small amount). The parameter estimates have been validated against independent data.

    Description / Table of Contents:
    Die Effektivität der Initiierung der Isoprenpolymerisation durch metallisches Lithium in Kohlenwasserstoffen läßt sich durch Aktivierung des Metalls mittels Vergrößerung seiner spezifischen Oberfläche und plastischer Deformation während des Syntheseprozesses wesentlich erhöhen, wodurch es möglich wird, zu α,ω-Dilithiumoligomeren ohne Einsatz von Elektronendonorzusätzen zu gelangen.
    Notes:
    The efficiency of the initiation reaction of the polymerization of isoprene by metallic lithium metal in hydrocarbon media can be increased essentially by activating the metal by increasing its specific surface and by its plastic deformation during the synthesis. The process opens up the possibility to prepare α,ω-dilithium oligomers without using electron donor additives.

    Notes:
    An all metal multistage low frequency vibration isolator for a laser interferometer gravitational wave detector has been built and tested with a very sensitive accelerometer. Curved cantilever springs are used to form a low frequency compact form of isolation element. Near center of mass suspension of the isolation stages reduces cross coupling between orthogonal directions. The isolator has a low-pass corner frequency of 6.5 Hz vertically and 1.8 Hz horizontally. The system shows low temperature coefficients and absence of creep. Results demonstrate that steel curved springs near their elastic limit do not generate broadband acoustic noise at the 10−15 m /(square root of)Hz level.

    Notes:
    Pendulum suspensions for laser interferometer gravitational wave detectors need to have an extremely high Q factor to minimize Brownian motion noise. In this paper we analyze the limits to the Q factor of the compound pendulum. We show that the observed acoustic loss of niobium can allow pendulum Q factors of 1010 to be achieved. This should enable a 3 km terrestrial laser interferometer detector to achieve strain sensitivity of 10−22/(square root of)Hz at frequencies as low as 10 Hz. At cryogenic temperatures Q factors up to 1012 should be achievable.

    Notes:
    Abstract Cells may affect oxygen transfer rates by three mechanisms: respiration of cells accumulated at the gas/liquid interface, physical presence of cells as solid particles, and modification of the medium by cells. These effects were studied experimentally in bubble-aerated bioreactors using baker's yeast at different cell concentrations, agitation speeds, aeration rates, and specific oxygen uptake rates. The overall effect of cells was to enhance oxygen transfer rates. The physical presence of cells as solid particles was found to retard oxygen transfer, presumably due to the lower oxygen permeability in the cell layer accumulated near the bubble surfaces. Cell respiration and medium modification, on the other hand, enhanced oxygen transfer rates. The retardation by nonrespiring cells and the enhancement due to cell respiration were found stronger at higher agitation speeds and lower aeration rates employed. This was attributed to the higher interfacial cell accumulation associated with the smaller bubbles produced under these conditions in the systems studied.

    Notes:
    Abstract Effective scale-up is essential for successful bioprocessing. While it is desirable to keep as many operating parameters constant as possible during the scale-up, the number of constant parameters realizable is limited by the degrees of freedom in designing the large-scale operation. Scale-up of aerobic fermentations is often carried out on the basis of a constant oxygen transfer coefficient, k L a, to ensure the same oxygen supply rate to support normal growth and metabolism of the desired high cell populations. In this paper, it is proposed to replace the scale-up criterion of constant k L by a more direct and meaningful criterion of equal oxygen transfer rate at a predetermined value of dissolved oxygen concentration. This can be achieved by using different oxygen partial pressures in the influent gas streams for different scales of operation. One more degree of freedom, i.e., gas-phase oxygen partial pressure, is thus added to the process of scale-up. Accordingly, one more operating factor can be maintained constant during scale-up. It can be used to regulate the power consumption in large-scale fermentors for economical considerations or to describe the fluid mixing more precisely. Examples are given to show that the results of optimization achieved in the bench-scale study can be translated to the production-scale fermentor more successfully with only a small change in the gas-phase oxygen partial pressure employed in the bench-scale operation.
