UK DRAFFT : a randomised controlled trial of percutaneous fixation with kirschner wires versus volar locking-plate fixation in the treatment of adult patients with a dorsally displaced fracture of the distal radius [PDF]

, 2011
Background: Fractures of the distal radius are extremely common injuries in adults. However, the optimal management remains controversial. In general, fractures of the distal radius are treated non-operatively if the bone fragments can be held in ...

Nitrogen fixation in the western English Channel (NE Atlantic Ocean) [PDF]

, 2009
In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has beendemonstrated by 2 independent measurements: 15N-N2 incorporation and nifH identification in theDNA and expressed messenger RNA (mRNA).

Optically induced refractive errors reduces fixation stability but saccade latency remains stable

Journal of Eye Movement Research, 2016
The purpose of this study was to investigate the effect of optically induced refractive errors on saccade latency and fixation stability. Sixteen healthy, young adults (two males), with normal visual acuity and normal accommodation, performed a saccade ...

Symbioses between cyanobacterial communities and feather mosses in boreal forests and consequences for dinitrogen fixation [PDF]

, 2013
Feather moss-cyanobacteria associations, although still poorly understood, are recognised as essential for the regulation of nitrogen (N) input into N-limited ecosystems such as boreal forests due to their ability to carry out N2-fixation.
