A Reduction Approximation Method for Curved Rods
Numerical Functional Analysis and Optimization, 2005 We study the numerical approximation of a general linear model for three-dimensional clamped curved rods. We introduce a modified system and we show that the convergence of the numerical discretization is independent of the small parameters entering the coefficients of the differential equations.

Characteristics of motile curved rods in vaginal secretions [PDF]
Journal of Medical Microbiology, 1983 Motile curved rods seen in vaginal secretions have been isolated on Columbia agar supplemented with 5% human blood and vitamin K. Growth occurred anaerobically and in 5% oxygen but not in more aerobic conditions. There were two distinct groups of these organisms, distinguishable by morphology, biochemical activity and susceptibility to metronidazole ...
