Stability of Spatial Optical Solitons,ante, — cela est avéré et depuis longtemps. Que ces couches, en revanche, transmettent aux manifestations climatiques, voire météorologiques, les effets, même atténués, étalés sur le temps, distribués sur la planète, de ces phénomènes solaires, cela est fortement contesté: les influences solaires so

Astronomical Activity in the Period 1600 to 1880information in Astronomy as a whole has been more rapid — by about a quarter — than that relating to the catalogues alone. The ratio of the sum of papers and the total number of catalogues within this period is doubled in 69 years span.

The Behaviour of Adiabatic Invariants Near Resonances variation of this adiabatic invariant becomes progressively larger as the time increases. Then we study the adiabatic invariant in the case of a simple pendulum with varying length. The changes of the adiabatic invariant are of the same order when the motion remains either oscillating or changes from oscillating to rotating.

Happi- ly, they were only few in number, and we should like to record our grat- itude to them for their good wishes for the success of the venture. Their warm words were among the many sources of inspiring encouragement extended to us.

A New, Rational Endeavour for Understanding the Eratosthenes Numerical Result of the Earth Meridian data..Lastly, a spontaneous hypothesis is advanced for the consideration of Hultsch’s stadium as an independent entity from the problem under consideration, and which could have been used by Eratosthenes in a given preliminary elaboration of his work.

https://doi.org/10.1057/9781403913692cluster in order to detect some possible parabolic profiles, we are faced with several observational difficulties; nevertheless, in the case of the Merope nebula, we do notice a distinctly parabolic boundary on its eastern side and this confirms indirectly the existence of dust in the close neighbourhood of star 23 Tau.
