Abstract: A Photonic Crystal Fiber (PCF) a method of its production and a supercontinuum light source comprising such PCF. The PCF has a longitudinal axis and includes a core extending along the length of said longitudinal axis and a cladding region surrounding the core. At least the cladding region includes a plurality of microstructures in the form of inclusions extending along the longitudinal axis of the PCF in at least a microstructured length section. In at least a degradation resistant length section of the microstructured length section the PCF includes hydrogen and/or deuterium. In at least the degradation resistant length section the PCF further includes a main coating surrounding the cladding region, which main coating is hermetic for the hydrogen and/or deuterium at a temperature below Th, wherein Th is at least about 50° C., preferably 50° C.<Th<250° C.

Abstract: The stability of an animal joint, especially a knee, is assessed with an arrangement having track arranged about perpendicular to the axis of the distal portion; a cart slidably engaged to the track; a fork positioned on the cart; a support adapted to receive the distal linear portion, the support connected to the fork; a lever arm connected to the support, the lever arm positioned to rotate the support about the axis of the distal portion; and at least one instrumented handle, the instrumented handle detachably engages at least one of the cart and the lever arm. In some embodiments, the fork can rotate freely on the cart. Additionally, in various embodiments, the cart may be selectively locked at a position along the length of the track. In various embodiments, the arrangement further comprises: a bracket rigidly attached to the distal portion and positioned between the support and the joint; and the at least one instrumented handle detachably engages the bracket.
