We present an analysis of 26 far-ultraviolet emission lines belonging to 19 atoms and ions observed on both sides of the boundary of polar coronal holes as well as other quiet Sun areas along the limb. The observations were made with the SUMER instrument (Solar Ultraviolet Measurements of Emitted Radiation) onboard the Solar and Heliospheric Observatory (SOHO). We compare line intensities, shif...

Two Self Organising Map neural networks have been trained to classify structures in the solar wind, one using Bz, n, and V, and the other using p and E. The classification has been done for values of the Dst index at -50, -100, -150, -200, and -250 nT, for events where the gradient of n and V exceeded a certain threshold (shocks as a result of coronal mass ejections) and for events where the gr...

BACKGROUND To determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves. METHODS All Adolescent Idiopathic Scoliosis (AIS) patients included in the study were classified according to Lenke and King Classification. The fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of T1 and ...

Abstract Using temporal observations of circular polarized harmonic plasma emission from a split-band type II solar radio burst at 80 MHz, we separately estimated the coronal magnetic field strengths ( B ) associated with lower L and upper U frequency bands burst. The corresponding Stokes I V data were obtained polarimeter operating above in Gauribidanur observatory. was flare/coronal mass ejec...

STUDY DESIGN A retrospective radiographic study. PURPOSE To evaluate the axial plane lumbar responses after anterior selective thoracic fusion (STF) in patients with main thoracic adolescent idiopathic scoliosis (MT-AIS). OVERVIEW OF LITERATURE Anterior scoliosis surgery induces more MT derotation through disc preparation than posterior surgery. METHODS Twenty-eight MT-AIS patients treate...
