On the nature of the z=0 X-ray absorbers: I. Clues from an external group

, 2007
Absorption lines of OVII at redshift zero are observed in high quality Chandra spectra of extragalactic sightlines. The location of the absorber producing these lines, whether from the corona of the Galaxy or from the Local Group or even larger scale ...

Innovation for Sustainable Development: Assessing Sustainability‐Oriented Innovations in the UK Palm Oil Supply Chains

Sustainable Development, EarlyView.
ABSTRACT This research evaluates the adoption of Sustainability‐Oriented Innovations (SOIs) by UK food manufacturers, particularly in the palm oil sector. Despite the global palm oil industry's environmental and social impacts, such as deforestation and labour exploitation, empirical studies on SOIs are limited. This paper addressed this gap by mapping

DWARF GALAXIES OF THE LOCAL GROUP [PDF]

Annual Review of Astronomy and Astrophysics, 1998
▪ Abstract  The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity determinations.

High‐Contrast Colorless‐to‐Colored Thermochromic Materials

Small, EarlyView.
We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

The curious case of J113924.74+164144.0: a possible new group of galaxies at z = 0.0693

, 2010
J113924.74+164144.0 is an interesting galaxy at z = 0.0693, i.e. D_L ~ 305 Mpc, with tidal-tail-like extended optical features on both sides. There are two neighbouring galaxies, a spiral galaxy J113922.85+164136.3 which has a strikingly similar 'tidal ...

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
