Abstract: An automated macromolecular method and system for detecting crystals in two-dimensional images, such as light microscopy images obtained from an array of crystallization screens. Edges are detected from the images by identifying local maxima of a phase congruency-based function associated with each image. The detected edges are segmented into discrete line segments, which are subsequently geometrically evaluated with respect to each other to identify any crystal-like qualities such as, for example, parallel lines, facing each other, similarity in length, and relative proximity. And from the evaluation a determination is made as to whether crystals are present in each image.

Abstract: The description relates to a backshell for a connector, consisting of a cylindrical metallic part (1) in which the cable (20) comprising a screening braid (21) is inserted and which comprises means for establishing electrical contact between the screening braid and the backshell. A non-metallic sleeve (2) is provided inside the backshell (1), which sleeve comprises webs (3) which extend substantially axially and are resilient radially to deflect inwards. A metallic clamping ring (4) is also provided, one end (4B) of which can be pushed over the webs (3) in the axial direction such that the screening braid (21) is clamped between the webs (3) and the clamping ring (4). A contact face of the clamping ring (4) bears against a pressure face (1B) of the backshell (1).
