Geopower, Geos and the Colonisation of Palestine

Transactions of the Institute of British Geographers, EarlyView.
ABSTRACT While the majority of geographical work on colonialism in Palestine centres on territory and land, this article foregrounds geopower and geos in the making of spatial relations. Three arguments are made over three corresponding sections. The first draws on recent writing on geopower and geos (primarily that by Elizabeth Grosz, Elizabeth ...

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Habitable Climates: The Influence of Eccentricity

, 2010
In the outer regions of the habitable zone, the risk of transitioning into a globally frozen "snowball" state poses a threat to the habitability of planets with the capacity to host water-based life. We use a one-dimensional energy balance climate model (

Reactivity of Cyanide at Water-Ice Interfaces: Implications for the Search for Organics on Icy Worlds

Frontiers in Astronomy and Space Sciences, 2020
Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of

Tidal Venuses: Triggering a Climate Catastrophe via Tidal Heating

, 2012
Traditionally stellar radiation has been the only heat source considered capable of determining global climate on long timescales. Here we show that terrestrial exoplanets orbiting low-mass stars may be tidally heated at high enough levels to induce a ...

General Relativity Can Prevent a Runaway Greenhouse on Potentially Habitable Planets Orbiting White Dwarfs

The Astrophysical Journal
Planets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

Habitable planetary environments and extraterrestrial life [PDF]

Chinese Science Bulletin, 2016
Arguably one of the most important discoveries in the history of human being is the detection of a planet orbiting a main sequence star beyond the solar system. By the time Science celebrated its 125th anniversary, ~150 exoplanets have been discovered. However, there was no known habitable exoplanet.

Survival of habitable planets in unstable planetary systems

, 2016
Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces these scatterings may also cause habitable planets in interior orbits to ...
