Evidence for accretion rate change during type I X-ray bursts

, 2013
The standard approach for time-resolved X-ray spectral analysis of thermonuclear bursts involves subtraction of the pre-burst emission as background. This approach implicitly assumes that the persistent flux remains constant throughout the burst.

A comparative study on the microstructural feature and band-gap value of FeOOH and α-Fe2O3 films electrodeposited at different temperatures

Heliyon
The morphology, microstructural and optical properties of electrodeposited FeOOH and α-Fe2O3 films were characterized using scanning electron microscopy, X-ray crystallography, Raman spectroscopy, and UV–Vis spectroscopy.

XTE J1739-302 as a Supergiant Fast X-ray Transient

, 2005
XTE J1739-302 is a transient X-ray source with unusually short outbursts, lasting on the order of hours. Here we give a summary of X-ray observations we have made of this object in outburst with the Rossi X-ray Timing Explorer (RXTE) and at a low level ...

Embodiment in Zande

, 2014
A number of body part terms of Zande have a wide range of metaphorical meanings. Most of these are purely lexical, only a few result from grammaticalization. Specific subsets of usages are linked to restricted sets of body part terms. Specific types of usages are carried out by restricted sets of bodypart terms.

Outburst of the X-ray transient SAX J1818.6-1703 detected by INTEGRAL in September 2003

, 2005
During the observation of the Galactic-center field by the INTEGRAL observatory on September 9, 2003, the IBIS/ISGRI gamma-ray telescope detected a short (several-hours-long) intense (~380 mCrab at the peak) outburst of hard radiation from the X-ray ...

Periodic Thermonuclear X-ray Bursts from GS 1826-24 and the Fuel Composition as a Function of Accretion Rate

, 2003
We analyze 24 type I X-ray bursts from GS 1826-24 observed by the Rossi X-ray Timing Explorer between 1997 November and 2002 July. The bursts observed between 1997-98 were consistent with a stable recurrence time of 5.74 +/- 0.13 hr.

Excuses gemaakt, zand erover? [PDF]

Tijdschrift voor Herstelrecht, 2019
Apologies offered, end of discussion? – The perception of emotional victims and the expected effects of apologies Whereas the starting point of victimisation is clearly marked by a co-occurence of harm and wrong, the end of victimhood is not as straightforward.
