  • Publication number: 20130097947
    Abstract: A steel structure including pre-stressing brackets for improving load-carrying capacity and serviceability comprises: a steel girder; a plurality of connecting brackets connected to the bottom surface of the steel girder spaced and apart from one; and a cover plate connected to the bottom surfaces of the connecting brackets. Since the cover plate is installed regardless of the connecting portion of the steel girder, pre-stressing section can be consecutively formed therefore pre-stress effect is improved. Moreover, since the connecting brackets space the cover plate a constant distance from the steel girder, the moment of inertia is increased so the span of a bridge might be increased.

  • Patent number: 8148541
    Abstract: Disclosed herein are rhodanine derivatives, a method for the preparation thereof, and a pharmaceutical composition containing the same. The rhodanine derivatives have inhibitory activity against protein phosphatases (PPase) such as PTP1B, Prl-3, LAR, CD45, Cdc25A, Cdc25B, Cdc25C, Yop, PP1 and VHR, and can be applied for the prevention and treatment of PPase-caused diseases, including autoimmune diseases, diabetes, impaired glucose intolerance, insulin resistance, obesity, cancers, etc. when the inhibitory activity thereof is modulated.

  • Patent number: 7745439
    Abstract: The inventive indene derivatives of formula (I) are capable of selectively modulating the activities of peroxisome proliferator activated receptors (PPARs), causing no adverse side effects, and thus, they are useful for the treatment and prevention of disorders modulated by PPARs, i.e., metabolic syndromes such as diabetes, obesity, arteriosclerosis, hyperlipidemia, hyperinsulinism and hypertension, inflammatory diseases such as osteoporosis, liver cirrhosis and asthma, and cancer.

  • Publication number: 20080128418
    Abstract: A vessel cap having a straw comprises a body mounted at a vessel inlet through which liquid material stored in a vessel is discharged outward, having a straw receiving portion at an upper surface thereof, and having a through hole at one side of the straw receiving portion; a straw horizontally disposed in the straw receiving portion of the body, and passing through the through hole thereby penetrating a sealing member formed at a vessel inlet when vertically positioned; and a connection film connected between an inner circumferential surface of the through hole of the body and an outer circumferential surface of the straw for guiding the straw to be vertically positioned. Once the straw is uprighted, the straw penetrates the sealing member. A user can drink the liquid material stored in the vessel by only one operation to open the cover thereby to enhance the user's convenience.
