    Notes: [Auszug] In the course of a study of the uptake and metabolism of cortisol by the human forearm3, we made the preliminary observation that following the intra-arterial injection of a mixture of l,2-3H-cortisol and 4-14C-cortisol into two healthy men, cortisol isolated from both arterial and venous plasma ...

    Notes: [Auszug] Macrocysts of DM-7 are postulated to contain at least one zygote. The fusion and karyogamy of two haploid cells of possible genotypes (aB) and (Ab) gives rise to a dihybrid of genotype (AaBb). Since DM-7 is homothallic, either parental genotype may fuse with itself as well, giving roughly equal ...

We have also ...

    Notes: [Auszug] SIR,?With reference to the article "The Unendangered Whale" (August 9), we feel that it is most important to point out that the opinions expressed by Dr Ray Gambell are by no means universally accepted. Gambell states that the "concept of species management is now operative". But 'concepts' do not ...

This is in contrast to the results of Matsumoto2. Attempts to observe a reddening of the visible light have ...

    Notes: [Auszug] SIR,? Brian Ford (Nature, August 2) may be right in saying that there is not enough statute law about bio-hazards, and his suggestions for future legislation are certainly valuable. But statutory codes of practice cannot by themselves solve the problem. Sooner or later, by accident or design, ...

    Notes: [Auszug] Here, I consider some implications of the mantle plume hypothesis on the basis of a simplified flow model. I represent the flow of the plume by viscous flow through a pipe. The Navier-Stokes equations, assuming steady state, fluid incom-pressibility and uniform viscosity, reduce to a simple form ...
