Abell 41: shaping of a planetary nebula by a binary central star?
, 2010 We present the first detailed spatio-kinematical analysis and modelling of the planetary nebula Abell 41, which is known to contain the well-studied close-binary system MT Ser.

A Novel Model of Patient Handover in Emergency Medicine—Addressing Hidden Tensions in Culture
AEM Education and Training, Volume 9, Issue 4, August 2025.ABSTRACT Introduction Clinical handover (or handoff), the transfer of patient care between providers, is essential in Emergency Medicine. Poor communication during handover can threaten patient safety. Existing literature views handover as an information transfer; little research has examined the human interaction within handover and how it affects ...

Dust in Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1989 The presence of dust in planetary nebulae can be deduced in several ways - from the observed depletions of condensable elements, internal extinction and, most directly, through the detection of infrared emission from the dust grains. We know that there is a substantial amount of dust in planetary nebulae, and that a significant fraction of the total ...

Classification of Planetary Nebulae through Deep Transfer Learning
Galaxies, 2020 This study investigate the effectiveness of using Deep Learning (DL) for the classification of planetary nebulae (PNe). It focusses on distinguishing PNe from other types of objects, as well as their morphological classification.

Rapid Communications in Mass Spectrometry, Volume 39, Issue 13, 15 July 2025.ABSTRACT Rationale Matrix effects by secondary ion mass spectrometry (SIMS) are empirically corrected by calibration using matrix‐matched reference materials. However, conventional parametric regression cannot estimate the prediction uncertainty to account for the difference in compositions of new data and reference materials. Applying Gaussian process

Fe/Ni ratio in the Ant Nebula Mz 3
, 2006 We have analyzed the [Fe II] and [Ni II] emission lines in the bipolar planetary nebula Mz~3. We find that the [Fe II] and [Ni II] lines arise exclusively from the central regions.

Confirmation of SBS 1150+599A As An Extremely Metal-Poor Planetary Nebula
, 2002 SBS 1150+599A is a blue stellar object at high galactic latitude discovered in the Second Byurakan Survey. New high-resolution images of SBS 1150+599A are presented, demonstrating that it is very likely to be an old planetary nebula in the galactic halo,
