Geodetic Precession in PSR J1141−6545 [PDF]
The Astrophysical Journal, 2005 We present observations that show dramatic evolution of the mean pulse profile of the relativistic binary pulsar J1141--6545 over a period of five years. This is consistent with precession of the pulsar spin axis due to relativistic spin-orbit coupling.

The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Business Strategy and the Environment, EarlyView.ABSTRACT This study assesses and compares the eco‐efficiency of six olive production systems in the Alentejo region, southern Portugal, employing a life cycle costing (LCC) approach directly integrated with a prior life cycle assessment (LCA). Although LCC has been increasingly applied to Mediterranean olive‐growing, empirical research in Portugal ...

X-ray observations of PSR J0218+4232 and of PSR B1937+21 [PDF]
International Astronomical Union Colloquium, 1996 Navarro et al. (1995) have discovered a 2.3 ms radio pulsar in a 2.0 day orbit around a low-mass companion. An interesting feature of this pulsar, PSR J0218+4232, is that radio emission is discovered throughout the pulse period; this is taken by Navarro et al. as an indication that the pulsar magnetic field is almost aligned with the rotation axis, and
