Winter Philopatry of Harlequin Ducks in Prince William Sound, Alaska
We used capture-mark-recapture data to assess winter philopatry by Harlequin Ducks (Histrionicus histrionicus) in Prince William Sound, Alaska, during winters 1995–1997 and 2000–2001. Philopatry was quantified using homing rates, which were estimated as the proportion of birds recaptured at their original site out of all recaptured birds. Between-year homing rates of 0.95 (95% CI: 0.87–1.00) an...
متن کاملAvian Influenza Ecology in North Atlantic Sea Ducks: Not All Ducks Are Created Equal
Wild waterfowl are primary reservoirs of avian influenza viruses (AIV). However the role of sea ducks in the ecology of avian influenza, and how that role differs from freshwater ducks, has not been examined. We obtained and analyzed sera from North Atlantic sea ducks and determined the seroprevalence in those populations. We also tested swab samples from North Atlantic sea ducks for the presen...

INTRODUCTION Forward fall-related distal radius fractures account for approximately 20% of all fractures and continue to be the most commonly seen by orthopaedic surgeons [1]. Regardless, our understanding of how these injuries result from dynamic, three dimensional impacts is limited. Duma et al. in 2002 [2] presented an injury risk criteria model for these fractures that included peak axial f...

Introduction: Experimental wear testing is well-established as an important part of the TKR design process. Recently, in-silico models have proved their value to corroborate long-term in-vitro results on a much shorter timescale [1]. Both FE-based models & multi-body dynamics can be used to predict contact pressures, sliding distances and cross-shear (CS). The precise mechanisms of wear are not...
متن کاملOne-stage exchange: it all began here.
Based on the first implementation of mixing antibiotics into bone cement in the 1970s, the Endo-Klinik has used one stage exchange for prosthetic joint infection (PJI) in over 85% of cases. Looking carefully at current literature and guidelines for PJI treatment, there is no clear evidence that a two stage procedure has a higher success rate than a one-stage approach. A cemented one-stage excha...
