Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Galactic bars and active galactic nucleus fuelling in the second half of cosmic history

Astronomy & Astrophysics
We investigate the role of galactic bars in fuelling and triggering active galactic nuclei (AGN) in disc galaxies up to z ∼ 0.8. We utilised a deep learning model, fine-tuned on Galaxy Zoo volunteer classifications, to identify (strongly and weakly ...

Metal-poor Stars in the MW Disk: Resonant Cooling of Vertical Oscillations of Halo Stars in Barred Galaxies

The Astrophysical Journal Letters
Using numerical simulations of a barred disk galaxy embedded in nonspinning and spinning dark matter (DM) halos, we present a novel mechanism of “cooling” the vertical oscillations of DM particles, which acquire disk kinematics.

Experimental and numerical analysis of the cyclic behaviour of RC beam-column connections with plain reinforcing bars [PDF]

, 2012
The information available in the literature about the cyclic behaviour of reinforced concrete elements with plain reinforcing bars is scarce. As a consequence, the influence of bar slippage in elements with plain bars is not yet comprehensively ...

Comparison of Bar Formation Mechanisms. I. Does a Tidally Induced Bar Rotate Slower than an Internally Induced Bar?

The Astrophysical Journal
Galactic bars can form via the internal bar instability or external tidal perturbations by other galaxies. We systematically compare the properties of the bars formed through the two mechanisms with a series of controlled N -body simulations that form ...

Bright galaxy number counts [PDF]

, 1995
The value of a plot of galaxy number counts per unit area of sky against magnitude as a probe of the early universe is well known, being influenced by both the curvature of expanding space and the deceleration parameter.

Counterrotation and Barred Galaxies [PDF]

International Astronomical Union Colloquium, 1996
AbstractIn this review we discuss the phenomenon of counterrotation, observed in ~40 apparently normal galaxies where gas or stars are rotating in a direction opposite to the main stellar body. It appears in all morphological types, from ellipticals to spirals or irregulars.The problem of the origin and the evolution of counterrotation is discussed, in

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.
