We present a system for the automatic retrieval of images with coronal loops from the solar image database captured by the SOHO/EIT satellite [1]. Our image retrieval system provides relevant data to astrophysicists who need such data to perform studies that shed light on the mysteries behind solar activities and to analyze the relations between coronal loops and other solar events. As part of ...

Coronal structure and coronal heating are intimately related in magnetically active stars. Coronal structure is commonly inferred from radio interferometry and from eclipse and rotational modulation studies. We discuss to what extent flares may be responsible for coronal structure and global observable properties in magnetically active stars.

A long-standing solar problem has been to measure the coronal magnetic field. We believe it determines the coronal structure and dynamics from the upper chromosphere out into the heliospheric environment. It is only recently that Zeeman splitting observations of infrared coronal emission lines have been successfully used to deduce the coronal magnetic flux density. Here we extend this technique...

Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal. Materials and Methods: F...

Coronal holes are the darkest and least active regions of the Sun, as observed both on the solar disk and above the solar limb. Coronal holes are associated with rapidly expanding open magnetic fields and the acceleration of the high-speed solar wind. This paper reviews measurements of the plasma properties in coronal holes and how these measurements are used to reveal details about the physica...

Supracondylar intercondylar distal femur fractures are devastating injuries that frequently have a concurrent coronal plane fracture, which mandates dedicated operative fixation. The purpose of this study was to determine whether small-fragment cortical lag screws oriented in the sagittal plane were sufficient to stabilize coronal plane fractures associated with supracondylar intercondylar dist...
