Abstract Based on recently opened multilingual archives, this paper addresses relationally three transnational cases of early networking for critical and radical geography that took place in different countries and languages between the 1970s and the 1980s.

The evolution of planetary nebulae VII. Modelling planetary nebulae of distant stellar systems
By means of hydrodynamical models we do the first investigations of how the properties of planetary nebulae are affected by their metal content and what can be learned from spatially unresolved spectrograms of planetary nebulae in distant stellar systems.

Close Binaries and the Abundance Discrepancy Problem in Planetary Nebulae
Motivated by the recent establishment of a connection between central star binarity and extreme abundance discrepancies in planetary nebulae, we have carried out a spectroscopic survey targeting planetary nebula with binary central stars and previously ...

(Re)wilding London: Fabric, politics, and aesthetics
Short Abstract Rewilding has become established as a new mode of nature conservation. Until recently, cities and the urban were neglected by rewilding discourse; the idea of urban rewilding seen as oxymoronic. Of late, however, there has been a shift, with growing enthusiasm amongst metropolitan authorities, civil society, and citizens in major cities.

Physiology of nitrogen: A life or death matter
Abstract With each breath, four out of every five molecules we inspire are nitrogen (N2), since this gas constitutes ∼80% of the atmospheric air that surrounds us. Despite its abundance and unlike molecular oxygen, N2 has traditionally held less appeal among physiologists given its lack of reactivity and corresponding inability to support combustion or

The diffuse extended outer regions of galaxies are hard to study because they are faint, with typical surface brightness of 1% of the dark night sky. We can tackle this problem by using resolved star tracers which remain visible at large distances from ...

On the Origin of Morphological Structures of Planetary Nebulae
We suggest that most of the mass in planetary nebulae (PNe) resides in the equatorial region and the spherical envelope and the optically bright lobes of PNe are in fact low-density cavities cleared out by fast outflows and photoionized by UV photons ...

Dust in Planetary Nebulae [PDF]
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 ...

A Novel Model of Patient Handover in Emergency Medicine—Addressing Hidden Tensions in Culture
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 ...
