We report the detection of an X-ray flare on the Bp star σ Ori E with the ROSAT high resolution imager (HRI). The flare is shown to have likely occurred on the early-type star, rather than on an hypothesized late-type companion. We derive flare parameters such as total energy release, coarse estimates of size and density, and also present arguments for a magnetic origin of the flare. We place o...

Selected Volatile Organic Compounds (VOC) emitted from various anthropogenic sources including industries and motor vehicles act as primary precursors of ozone, while some VOC are classified as air toxic compounds. Significantly large VOC emission sources impact the air quality in Corpus Christi, Texas. This urban area is located in a semi-arid region of South Texas and is home to several large...

A technique is described for the quantitative assessment of peripheral nociceptive C fibre function by measurement of the axon reflex flare. Acetylcholine, introduced by electrophoresis, is used to stimulate a ring of nociceptive C fibre endings at the centre of which the increase in blood flow is measured with a laser Doppler flowmeter. This flare (neurogenic vasodilatation) has been compared ...

The RSCVn system σ Geminorum was observed by XMM-Newton on April 2001 during a large flare. We model the emission measure distribution (EMD) during the flare and during a quiescence period. In the flare, a two phase behaviour is found in which the cool plasma (kT < 2 keV) is not disturbed while a large hot component , at temperatues of kT > 3 keV emerges. Fundamental limitations on EMD modeling...

We have performed the first polarimetry of solar flare emission at γ-ray energies (0.2–1MeV). These observations were performed with the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) for two large flares: the GOES X4.8-class solar flare of 2002 July 23, and the X17-class flare of 2003 October 28. We have marginal polarization detections in both flares, at levels of 21 ± 9% and -...

Alkaline phosphatase (ALP) flare phenomenon documented as scintigraphic flare phenomenon due to elevated serum ALP levels produced by osteoblasts reflects an osteoblastic reaction in response to the effective therapy of non-small cell lung cancer (NSCLC). Here, we report a case of ALP flare following gefitinib treatment for NSCLC. We also retrospectively analyzed the prevalence of ALP flare in ...

The Solar Optical Telescope (SOT) on board Hinode satellite observed an X3.4 class flare on 2006 December 13. Typical two-ribbon structure was observed, not only in the chromospheric Ca II H line but also in G-band and Fe I 6302 Å line. The high-resolution, seeing-free images achieved by SOT revealed, for the first time, the sub-arcsec fine structures of the “white light” flare. The G-band flar...

We investigate a model for the decay of flare heated coronal loops in which rapid radiative cooling at the loop base creates strong pressure gradients which, in turn, generate large (supersonic) downward flows. Hence, the coronal material cools and "condenses" onto the flare chromosphere. The important features of this model which distinguish it from previous models of flare cooling are: (1) Mo...

There was a significant association of flare with ED; men with flare reported significantly more ED than men without ( P = 0.020). Men with high-risk disease reported more ED because they received more intensive treatment (hormones and increased radiation dose) than men with mediumor low-risk disease. To correct for this confounding factor, multivariate linear regression was used; the regressio...

Systemic juvenile idiopathic arthritis (SJIA) is a chronic arthritis of children characterized by a combination of arthritis and systemic inflammation. There is usually non-specific laboratory evidence of inflammation at diagnosis but no diagnostic test. Normalized volumes from 89/889 2-D protein spots representing 26 proteins revealed a plasma pattern that distinguishes SJIA flare from quiesce...
