A 7-year-old male llama was examined for a 3-month history of weight loss, and unilateral keratouveitis. Clinical examination revealed nonulcerative corneal stromal abscessation, corneal vascularization, corneal edema, miosis, posterior synechia, cataract, and fibrin in the anterior chamber of the right eye.

The effect of vehicle characteristics on drivers' risk-taking behaviour.

There is evidence linking certain vehicle characteristics to crash involvement and one possible mechanism behind this relationship is that these vehicle characteristics influence drivers' risk-taking behaviour. In order to investigate this, we conducted a roadside observation survey and a questionnaire-based study. Both revealed a significant relationship between vehicle performance and drivers' risk-taking behaviour.
