... A. M. Neminsky, D. V. Shovkun, and O. T. Vyaselev . ... Received 18 January 1996 . The temperature dependence of ac susceptibility chi ( T ) has been measured at different values of dc magnetic field for Rb 3 C 60 fine powder. ... The chi ( T ) measurements at different dc magnetic fields allow us to distinguish between these two contributions and to obtain precisely the temperature dependence of the London penetration depth lambda ( T ). ...
... These are just the bare bones--just three basic ideas and rules for handling relations ("equations") involving unknown quantities whose values you are trying to find. In most calculations you try to find a number . ... To get a solution, one must replace the given equation (or equations) with others, containing the same information but cleaner in appearance. ... If you have an equation and modify both its sides in exactly the same way, what you get is also a valid equation. ...
... AR12381 (N06L073, Sp max=550 msh, M/2)-the bipolar sunspot group stret- ched on longitude appeared on east limb 2.07 in a quiet state, however at the end of the days 5.07 in a middle part there was a new quickly emerging magnetic flux which already in the first half of the next days led to occurred of flare of X-ray class M1, and in 10 hours to flare 2N/ M1.7. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...
