Abstract: The present invention provides a temperature sensitive hydrogel composition including a nucleic acid and chitosan. Since the hydrogel has excellent biocompatibility and biostability, and simultaneously has sol-gel phase transition properties depending on temperature changes, the hydrogel is present in a sol state at room temperature and becomes a gel when the hydrogel is injected into the human body or applied on the surface of epithelial skin and the temperature increases. Thus, the temperature-sensitive hydrogel of the present invention can be directly injected into and applied on certain parts requiring treatment and the retention and attaching time of a drug is increased through gelation depending on the temperature so that drug efficacy is sufficiently exhibited. Therefore, it is expected that the temperature-sensitive hydrogel of the present invention can be utilized for various treatments.

Abstract: A burner includes a burner inlet and outlet. The burner also includes a primary conduit defining a flow channel extending along a burner axis for conveying a mixture of fuel and gas and a secondary conduit defining a flow channel disposed about the primary conduit for conveying gas. The primary conduit defines a flow channel extending to a primary conduit outlet within the burner substantially upstream of the burner outlet, whereby the secondary conduit downstream of the primary outlet defines a common conduit for flow from the primary and secondary conduits. A swirl generation device imparts a swirl to the flow of gas from the secondary conduit upstream of the primary conduit outlet. A venturi arrangement is provided in the vicinity of the primary outlet to act on the primary flow stream to impart a flow deviation.
