A continuous flow irrigation endoscope and a continuous flow irrigation fluid management system, both designed to be compatible to each other and meant to function as a single system. The endoscope and the fluid management system are synergistic to each other such that both enhance the efficiency of each other. The system allows a body tissue cavity to be distended by continuous flow irrigation so that the detached tissue pieces and waste fluid present inside a body tissue cavity are continuously automatically evacuated from the tissue cavity without causing the cavity to collapse at any stage and without the need of withdrawing the endoscope or a part of the endoscope from the tissue cavity.

A method and system for fabricating a device on a substrate with a process gas, such as with chemical vapor deposition. A reaction chamber and support chuck cooperate to form a low conductance configuration for axisymetric process gas flow over the substrate and to form a high conductance configuration for enhanced evacuation of residual process gas from the reaction chamber upon completion of the process. A dual conductance chuck has an indented region that aligns with the exhaust port of the reaction chamber to restrict process gas flow in the low conductance configuration, and that moves distal a showerhead and the exhaust port to provide reduced restriction of process gas flow for reaction chamber evacuation. The chuck includes thermal control for enhancing film deposition on the substrate and for reducing residual film deposition on the chuck. An evacuation opening in the housing provides independent evacuation of residual gas from the housing. The present invention enhance throughput of device formation by reducing purge and process cycle times.

A geosynthetic reinforcement comprising a container formed of semipermeable material mutually conformed with a portion of earthen material contained therein. A structural member such as a geogrid may engage (e.g. frictional) the container and extend therefrom to engage and support a structure such as a retaining wall, earthen slope, etc. Accordingly, the container may function as an anchor to the structure. Due to the containment provided by the container, the physical characteristics of the earthen material therewithin become less important. Thus, low quality fills such as fine-grained fill or fill with a high moisture content may be used in structural applications. If desired, more than one container and structural member may be incorporated. Containers may be stacked, positioned side-by-side, positioned end-to-end, etc. Structural members may be incorporated as needed to adequate support the structure. Drain layers may be incorporated to control moisture. In some cases, containers may comprise geotextile tubes.
