Abstract: An apparatus for forming a fiber from a biocompatible biopolymer includes a fiber-formation tube that defines a bore extending generally vertically from an upper end to a lower end. Coagulation fluid enters the tube through a fluid inlet coupled to its upper end and establishes a laminar flow of coagulation fluid within the tube. A spinneret introduces a stream of liquid biopolymer into the laminar flow of coagulation fluid so that the stream is surrounded and swept downstream by the coagulation fluid as it coagulates into a biopolymer fiber. The laminar flow of coagulation fluid surrounding the biopolymer stream maintains the shape of the stream so that the resulting fiber is homogeneous in both geometry and structure. The laminar flow of coagulation fluid also prevents the resulting fiber from contacting the inner wall of the fiber-formation tube.

Abstract: In a rear holder-attached connector (1), a relatively-thick protective rib (10) with a width (B) projects outwardly from opposite sides of a housing (2), and is disposed between upper and lower terminal receiving chambers (3). This width (B) is larger than a width of rear holders (20a, 20b), and this rib (10) protects the rear holders (20a, 20b) so that these rear holders, provisionally retained on the housing (2) within a metal-mold assembly, will not be discharged from the metal-mold assembly to drop, and will not be disengaged from the housing even upon contact with another housing. The provision of the protective rib (10) also serves to provide a good flow of a resin poured from the rear side of the housing (2) during the molding operation, and therefore thin partition walls, forming the terminal receiving chambers (3), can be positively molded, thereby enhancing the yield of the molded housings.

Abstract: A method and system for creating and maintaining assessments involving using an interface device, connected to an electronic and/or communications channel(s), to access an assessment control system in order to identify information related to information content and develop assessment items. User activity within an interface device occurs within an environment in which multiple components are present in a manner that produces a continuous unified perceptual experience. Thus users can create and maintain assessment information while in the presence of the information content, which most likely represents, either directly or indirectly, the material or subject for which an assessment is being created. User activities within one component do not material affect or disturb information in other components unless the user intentionally chooses to alter other components.
