Polar surges and macrospicules

Polar surges and macrospicules : simultaneous H α and He II 304 Å observations

We compare simultaneous sequences of Hα and He ii 304Å images near the solar limb. We propose to distinguish polar surges and giant spicules (macrospicules), among the He ii structures observed beyond the solar limb. Polar surges have a complex structure when observed in Hα and an erup-tive nature, reminiscent of normal surges in small scale. Giant spicules are simple spikes, very narrow compar...

Solar spicules and macrospicules observed by SUMER

Motivated by recent observations of spicules and macrospicules in the far-ultraviolet (FUV) wavelength range with the Solar Ultraviolet Measurements of Emitted Radiation spectrograph (SUMER) on the Solar and Heliospheric Observatory (SOHO), a generation mechanism for spicules and macrospicules is outlined which deviates significantly from most of the previous concepts. The important aspect is t...

Orthopaedics Surges Ahead.PDF

The year 2007 marked the 60th year of Indian Independence, but a sizable number of Indians are waiting to be freed from the gripping pain in their joints and bones. What these patients would like is to reduce, if not end their suffering and improve the health-related quality of life. This is exactly what the Bone and Joint Decade (BJD) — a multi-disciplinary international initiative supported b...

m-polar intuitionistic graphs and its properties

In many real world problems, data sometimes comes from n agents (n≥2), multipolar information exists. For issues that are associated with uncertainty, this information can not be showed with the values of crisp, fuzzy, intuitionistic or bipolar. Graph is one of the mathematical models widely used in different sciences. Ambiguity in a graph where data depends on the n parameter can not be showed...
