Discovery of Enhanced Germanium Abundances in Planetary Nebulae with FUSE

open access: yes, 2002
We report the discovery of Ge III $\lambda$1088.46 in the planetary nebulae (PNe) SwSt 1, BD+30$^{\rm o}$3639, NGC 3132, and IC 4593, observed with the Far Ultraviolet Spectroscopic Explorer.

The Oxygen Abundance in the Solar Neighborhood

open access: yes, 2011
We present a homogeneous analysis of the oxygen abundance in five H II regions and eight planetary nebulae (PNe) located at distances lower than 2 kpc and with available spectra of high quality.

Periodic Variability of the Central Stars of Planetary Nebulae Surveyed through the Zwicky Transient Facility

open access: yesThe Astrophysical Journal
A consensus has been reached in recent years that binarity plays an important role in the formation and evolution of a significant fraction of planetary nebulae (PNe).

Antitussive, expectorant and analgesic effects of the ethanol seed extract of Picralima nitida (Stapf) Th. & H. Durand

open access: yesResearch in Pharmaceutical Sciences, 2016
Picralima nitida is used traditionally for management of cough. This study, therefore, investigated the antitussive, expectorant, and analgesic properties of the ethanolic seed extract of Picralima nitida (PNE), and ascertained its safety for use ...

Effect of DRD4 receptor −616 C/G polymorphism on brain structure and functional connectivity density in pediatric primary nocturnal enuresis patients

open access: yesScientific Reports, 2017
The dopamine D4 receptor (DRD4) promoter (−616; rs747302) has been associated with primary nocturnal enuresis (PNE); however, its relationship with neuroimaging has not been investigated.

The Gaia Data Release 1 parallaxes and the distance scale of Galactic planetary nebulae

open access: yes, 2017
In this paper we gauge the potentiality of Gaia in the distance scale calibration of planetary nebulae (PNe) by assessing the impact of DR1 parallaxes of central stars of Galactic PNe (CSPNe) against known physical relations.

IFU spectroscopy of southern PNe: III

open access: yes, 2016
In this paper we describe integral field spectroscopic observations of four southern Galactic Planetary Nebulae (PNe), M3-4, M3-6, Hen2-29 and Hen2-37 covering the spectral range, 3400-7000 A. We derive the ionisation structure, the physical conditions, the chemical compositions and the kinematical characteristics of these PNe and find good agreement ...

From didactic explanations to co-design, sequential art and embodied learning: challenges, criticisms and future directions of patient pain education

open access: yesFrontiers in Pain Research
Pain Neuroscience Education (PNE) emerged over two decades ago in response to the incoherence between evidence-based pain management strategies, and consumer and clinician understandings of “how pain works”.
