Determination of the Coronal and Interplanetary Magnetic-Field Strength and Radial Profiles from the Large-Scale Photospheric Magnetic Fields
A new model has been proposed for magnetic field determination at different
distances from the Sun during different solar cycle phases. The model depends
on the observed large-scale non-polar photospheric magnetic fields and that
measured at polar regions from 55N to 90N and from 55S to 90S,which are the
visible manifestations of cyclic changes in the toroidal and poloidal
components of the global magnetic field of the Sun. The modeled magnetic field
is determined as the superposition of the non-polar and the polar photospheric
magnetic field cycle variations. The agreement between the model predictions
and magnetic fields derived from direct, in-situ, measurements at different
distances from the Sun, obtained by different methods, and at different solar
activity phases is quite satisfactory. From a comparison of the magnetic fields
as observed and as calculated from the model at 1 AU, it should be concluded
that the model magnetic-field variations adequately explains the major features
of the IMF Bx component cycle evolution at the Earth's orbit. The model
CR-averaged magnetic fields correlate with CR-averaged IMF Bx component at the
Earth's orbit with a coefficient of 0.688, and for seven CR-averaged data the
correlation reaches 0.808. The model magnetic-field radial profiles were
compared with that of the already existing models. In addition, the decrease in
the non-polar and polar photospheric magnetic fields has been revealed. Both
magnetic fields during solar cycle maxima and that during minima phases
decreased from Cycle 21 to Cycle 24. It means that both the toroidal and
poloidal components and therefore, the solar global magnetic field decreased
from Cycle 21 to Cycle 24.Comment: 27 pages, 6 figures, 2 table
An Exploration into the Use of Rhythm in Devising Movement for Theatre
Within this thesis the use of rhythm in the movement devising process is explored. Specifically investigating how rhythm can be used in the movement devising process in order to harness its various expressive qualities. These qualities include symbolic associations, such as natural and mechanical rhythms, as well as broader tonal effects on energy, tension, and mood. Also addressing more specific effects that can be used in the portrayal of character, intention, and subtext. Technical aspects of rhythm are discussed, such as tempo and metre, sequence and repetition, and polyrhythm. Also considering how understandings of rhythm drawn from key historical practitioners can be applied. These include Konstantin Stanislavsky’s tempo-rhythm, Vsevolod Meyerhold’s tri-partite rhythmic structure, and Rudolf Laban’s effort theory. The study also draws on more contemporary sources, including the work of Eilon Morris. A selection of exercises are presented, with which devisers can practically explore the aspects and understandings of rhythm discussed within the thesis
Emerging countries as a future market leader
A modern world is changing very fast and the leadership of United States of America and Europe is becoming weaker than a few years ago. Nowadays some emerging countries are now trying to become the future economics‘ leaders. Such countries as Brazil, China and India have fast growing economies which will soon be even more effective than the western economies. They are taking more space in the international trade. This new dimension of the economy opens a lot of new opportunities to companies and organizations which are not afraid of investing abroad
