    Notizen: [Auszug] Models of mantle convection have been proposed with several different combinations of convecting layers, including convection confined to the upper mantle, convection in separate layers in the upper and lower mantle, and whole-mantle convection2-10. The models of double-layer convection have been ...

    Notizen: [Auszug] The ABC-1 cells are large, vacuolated, undifferentiated blast cells. Immunofluorescence and cytotoxicity tests indicated that no cells had cell surface immunoglobulin (Smlg) or expressed detectable levels of Thy-1.2, suggesting that there were no mature B or T lymphocytes present. Additional ...

    Notizen: [Auszug] How hot did it get? That question was on the minds of meteoriticists gathered in Washington DC this September*. While autumn breezes cooled the Mall, scientists meeting deep underground presented convincing evidence that the early solar nebula was considerably hotter than has been thought likely ...

    Notizen: [Auszug] How massive can a giant planet be? What is the lowest mass for a brown dwarf star? The answers to both of these questions have changed because of observations presented at a recent meeting187th Meeting of the American Astronomical Society, San Antonio, USA, 14-18 January 1996.Geoffrey W.

    Notizen: [Auszug] How long did the earliest phases of planet formation last in the inner Solar System? New measurements of aluminium isotope abundances in primitive meteorites imply that rocky solids were formed in a dusty disk over a period of about 10 million years (Myr). That period of ...

    Notizen: [Auszug] Size does matter, especially when it comes to radio telescopes. With a maximum extent of 36 km, the Very Large Array (VLA) of 27 radio telescopes yields sharper images at millimetre wavelengths than any other instrument. Rodríguez et al., reporting on page 355 of this issue, have ...

    Notizen: [Auszug] The discovery of giant planets orbiting nearby solar-type stars raises anew the question of how they formed. Two very different mechanisms have been proposed. Gravitational instability, is the process by which planets form directly from the gas in the accrection disk around the young star. The ...

    Notizen: [Auszug] EXPERIMENTS designed to explore the control of antibody production have revealed for the first time the existence of enhancer sequences in eukaryotic genes. Enhancers, until now identified only in viruses, are short regulatory sequences that increase the rate of transcription from many eukaryotic ...

    Notizen: [Auszug] The two cell lines used in our study, 40E4 and 22D6, were produced by Abelson murine leukaemia virus (A-MuLV) transformation of BALB/c fetal liver at 13-14 and 17-19 days of gestation, respectively. These cell lines produce no detectable immunoglobulin12; they possess DJH rearrangements on both ...

    Beschreibung: Abstract Two Bio‐Argo floats measured the concentration of chlorophyll‐a, the backscattering coefficient, the fluorescence of humic‐like dissolved organic matter, dissolved oxygen, and temperature and salinity in the northern and central basins of the South China Sea for over 2 years. Temporal evolutions of bio‐optical properties were analyzed at surface, subsurface, and in the whole water column, respectively. It was found that (1) The seasonal variability of the surface chlorophyll‐a was highly controlled by photoacclimation, especially in the central basin; (2) backscattering in the upper 150 m was nearly constant, exhibiting no distinct seasonality; (3) with vertical mixing, particles from the deep chlorophyll maxima were entrained into the mixed layer resulting in enhanced surface chlorophyll during the early winter. This phenomenon may mislead a study based on satellite data which is likely to interpret it as blooming rather than a redistribution of phytoplankton within the water column; (4) analysis of a winter bloom and an anticyclonic eddy reveal that physical entrainment and biological photoacclimation modulated the vertical distributions of chlorophyll‐a and particles and potentially also changes of phytoplankton community composition; and (5) fluorescent dissolved organic matter was found to be highly coupled to phytoplankton dynamics in both basins, with a maximum (after removing the contribution of physical convective mixing) located at the depth of chlorophyll‐a subsurface maximum.
