We point out the priority of our paper (Mahajan et al. 2001) over (Aschwanden et al. 2007) in introducing the term ”Formation and primary heating of the solar corona” working out explicit models (theory as well as simulation) for coronal structure formation and heating. On analyzing the (Aschwanden et al. 2007) scenario of coronal heating process (shifted to the chromospheric heating) we stress...

The goal of this general article is to present a survey of the current knowledge about the clinical approach of restoring endodontically treated teeth. The best way to restore teeth after root canal treatment has long been and still is a controversial subject of debate to this day. The clinical approach of restoring endodontically treated teeth needs taking into consideration several issues: ai...

The aim of this study was to compare the resistance of endodontically treated teeth with intraradicular retainer different amounts of remaining coronal structure. Fifty freshly extracted maxillary canines were endodontically treated and randomly assigned to five groups (n=10), as follows: group 1 (control) = teeth with custom cast post and core; group 2 = teeth without remaining coronal structu...

Hypospadias is a highly prevalent congenital anomaly. English articles, indexed in PubMed, published the long-term sexual and reproductive outcome following hypospadias repair. Almost all repairable cases of hypospadias are operated in childhood. Although distal hypospadias does not interfere with fertility, it is worthy reporting a case of an elderly man, who fathers 12 children and has no uro...

We provide evidence for the existence of a new type of soft X-ray (SXR) brightening event that we call coronal flashes. The phenomenon was observed on deep time series taken with the SXT of Yohkoh in the north polar coronal hole, near the sunspot minimum. Events last as short as 1.5 mn and the corresponding SXR flux span the range of energies, from single pixel brightenings corresponding to flu...

Coronal events such as flares or coronal mass ejections derive their energy from the energy stored locally in the magnetic field. This leads to the conjecture that a magnetic implosion must occur simultaneously with the energy release. The site of the implosion would show the location of preflare energy storage, and its detection should have a high priority. The Transition Region and Coronal Ex...

An empirical model for forecasting solar wind speed related geomagnetic events is presented here. The model is based on the estimated location and size of solar coronal holes. This method differs from models that are based on photospheric magnetograms (e.g., Wang-Sheeley model) to estimate the open field line configuration. Rather than requiring the use of a full magnetic synoptic map, the meth...

0. Introduction This study documents and analyzes opacity in the coronal harmony of Kinyarwanda. This harmony presents several features of interest. First, the existence of opacity in coronal harmony is rare: to the best of our knowledge it has only previously been reported in Sanskrit’s nasal retroflex harmony. In Kinyarwanda the harmony audibly affects only sibilants, and it is blocked by cor...

The efficacy of radiographic methods in detecting and classifying facial fractures was assessed. Thirty-one patients with maxillofacial trauma were studied with plain radiography, coronal and lateral pluridirectional tomography (PT), and axial and direct coronal computed tomography (CT). PT and CT were compared to assess how many fractures each method could demonstrate. In addition, plain films...

We identify coronal holes using a histogram-based intensity thresholding technique and compare their properties to fast solar wind streams at three different points in the heliosphere. The thresholding technique was tested on EUV and X-ray images obtained using instruments onboard STEREO, SOHO and Hinode. The full-disk images were transformed into Lambert equal-area projection maps and partitio...
