Abstract: The present invention discloses groundwater heat transfer system comprising a primary pump suspended in a well and connected to at least one water supply pipe, a heat exchange system being connected to said primary pump via a secondary pump, a return pipe being connected to the heat exchange system and returning water from the heat exchange system to the well, wherein the primary pump provides motive pressure to a primary nozzle of a liquid jet ejector submerged in the well, which entrains filtered groundwater through a secondary nozzle of the liquid jet ejector, wherein the secondary pump, placed after the primary pump and before the heat exchange system, provides the remaining system head.

Abstract: The present invention relates to a method for preparing high-purity ginsenoside Rd using Lactobacillus casei, more particularly to a method for preparing high-purity ginsenoside Rd using Lactobacillus casei and an anti-wrinkle cosmetic composition comprising the high-purity ginsenoside Rd as an active ingredient. Since the method of the present invention is simple and can economically prepare high-purity ginsenoside Rd extract, it may make the best use of anti-wrinkle effect of the ginsenoside Rd. In addition, the present invention can increase stability and decrease skin irritation by preparing water-soluble molecular capsule of high-purity ginsenoside Rd, thereby having advantage of increasing applicability ginsenoside Rd radically.

Abstract: Novel compositions containing conjugated linoleic acids are efficacious as animal feed additives and human dietary supplements. Linoleic acid is converted to its conjugated forms in which the resulting composition is low in certain unusual isomers compared to conventional conjugated linoleic products. In addition, the inventions provides compositions that are prepared according to a novel method that controls oxidation of CLA into volatile organic compounds as well as containing metal oxidant chelators to control oxidation during storage.
