A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient. The catheter facilitates mixing of fresh and spent dialysate inside the peritoneal cavity by inflowing fresh dialysate into the cavity at a location substantially separated from the cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.

The present invention is a fuel cell power plant that includes a fuel cell having a membrane electrode assembly (MEA), which is disposed between an anode support plate and a cathode support plate, and porous water transport plates adjacent the anode and cathode support plates. The porous water transport plates have interdigitated flow channels for the reactant gas streams to pass therethrough and conventional flow channels for a coolant stream to pass therethrough. The fuel cell power plant also has means for creating a pressure differential between the reactant gas streams and the coolant stream such that the pressure of the reactant gas streams is greater than the coolant stream. Incorporating the interdigitated flow channels into the porous water transport plates and operating the fuel cell at a pressure differential allows the coolant water to saturate the water transport plates thereby forcing the reactant gases into the anode and cathode support plate. This, in turn, increases the mass transfer of such gases into the support plates, thereby increasing the electrical performance of the fuel cell. Current densities of about 1.6 amps per square meter are achieved with air stochiometries of not over 2.50.

A novel method is set out of preparation of radioactive diagnostic radiopharmaceutical in a stable, shippable, lyophilized form by an apparatus designed to rapidly flash freeze and dehydrate a radiopharmaceutical composition to minimize auto radiolysis. The method proposes rapid cooling and removal of ambient vapor, and then ultra cold removal when the potential of explosive liquid oxygen is eliminated. The radioactive diagnostic radiopharmaceutical requires no further cold or refrigerated storage, including with respect to shipping, subsequent to stabilization. The preferred composition can be reconstituted “on site” by the addition of a suitable diluent to bring the radiopharmaceutical complex into solution at a desired concentration.

Incorporation of a microbial cell suspension throughout a fibrous network provides a physical environment that allows greater removal of water during lyophilization or desiccation thereby yielding a device with improved stability and recovery of viable microbial cells. Strands of appropriate fibers in a tightly knit network absorb aqueous cell suspensions by a capillary effect rather than absorption. When vapor pressure is decreased by vacuum during lyophilization or by air moved during desiccation, the surface tension is affected at the fiber / water interface, which results in increased water removal, by a “reverse capillary” effect. Thus bound and free water removal is increased. Therefore, incorporation of the use of a network of fibers in conjunction with a preservation matrix containing sensitive microbial cells provides a means of producing a preserved product with increased stability at both extreme and routine storage temperatures and greater efficacy for the end user. The invention also provides a means for recovery of viable microbial cells by direct inoculation to solid or liquid culture media as recommended for use in performance or quality control testing of culture media, stains, identification kits, maintenance of stock cultures and in the evaluation of bacteriological procedures. Additionally, the device can be used to mimic clinical specimens in clinical or industrial proficiency testing surveys that test the ability of laboratory technologists to properly perform diagnostic procedures.

Thermo-grid of insulated composite strapping is mounted on the surface of the said wall and a layer of continuous insulation e.g. polyurethane foam is applied between the thermo-grid strapping leaving a thin air gap between it and the next layer of the fire protective composite.

Fuel Cell Having a Hydrophilic Substrate Layer A fuel cell power plant includes a fuel cell having a membrane electrode assembly (MEA), disposed between an anode support plate and a cathode support plate, the anode and / or cathode support plates include a hydrophilic substrate layer having a predetermined pore size. The pressure of the reactant gas streams is greater than the pressure of the coolant stream, such that a greater percentage of the pores within the hydrophilic substrate layer contain reactant gas rather than water. Any water that forms on the cathode side of the MEA will migrate through the cathode support plate and away from the MEA. Controlling the pressure also ensures that the coolant water will continually migrate from the coolant stream toward the anode side of the MEA, thereby preventing the membrane from becoming dry. Proper pore size and a pressure differential between coolant and reactants improves the electrical efficiency of the fuel cell.
