    Notes: [Auszug] IN spite of all the constraints desert conditions impose on human activity, they do generate in the individual a great sense of freedom. This, perhaps, explains why so many of those whose names are so closely linked with arid regions were, above all, great individualists. Arabian explorers like ...

    Notes: [Auszug] Our studies were carried out between September and March during when almost all the monkeys in our colonies have ovulatory menstrual cycles. We used adult female rhesus monkeys (5-6 kg) which had experienced at least two successive ovulatory menstrual cycles of normal duration (20-33 d) (determined ...

    Notes: [Auszug] THERE is a long standing joke that one can doze off during one of Wagner's Ring of the Nibelungen operas, only to wake up ten minutes later to find the same singer standing on the same spot singing the same song.

    Notes: [Auszug] NATURAL uranium, unaugmented by breeding, will provide a relatively small reserve of energy: uranium energy reserves amount to only one-fifth those of oil. The best-promoted nuclear solutions to this problem are the fast breeder reactor (FBR) and controlled fusion. The former is a means of ...

    Notes: [Auszug] THE world will need a new source of energy when the oil and gas runs out: on that most are agreed, from the Friends of the Earth to the toughest champions of the nuclear industry. But how much energy? By when? And from what source? These are highly political questions, but they involve a technical ...

    Notes: [Auszug] SINCE the first expedition, just 50 years ago, to the site of the "Tungus event" of 1908, the explosion has posed a major riddle to geophysicists. The latest in a long line of theories, that of a certain Aleksei Zolotov, poses a further mystery-how, in the conditions prevailing in Soviet science, ...

    Notes: [Auszug] THE charge and matter distributions of nuclei, and their magnetic moments, are important features of nuclei, and many efforts are being made to determine them with increasingly high precision. It is often instructive to see how they change through a series of isotopes of the same element, but such ...

    Notes: [Auszug] The performance of photogalvanic cells for the direct conversion of solar energy to electrical energy depends on the cell photochemistry, the homogeneous kinetics, the mass transport, the electrode kinetics and the load on the cell. The variation of the power output with the concentrations of the ...
