  • Patent number: 8609858
    Abstract: The present invention relates to novel spiro derivatives of parthenin prepared by the dipolar cycloaddition of various dipoles viz, benzonitrile oxides, nitrones, azides, nitrile ylide diazoalkane, nitrile imide, ozone, azomethine imides, azomethine ylides etc. with exocyclic double bond of C ring (?-methylene-?-butyrolactone). Representative compounds have been screened for their anticancer activity against different cancer cell lines. ICs0 value of these analogues varies between 4.3 ?M to 93 ?M. A mechanistic correlation of their anticancer activity has been described. The results of the cytotoxicity test of the compounds studies indicated that the ?,?-unsaturated ketonic moiety in parthenin plays an important role in the maintenance of the high level of cytotoxicity.

  • Patent number: 8594816
    Abstract: A method for determining the task load in real-time. The method takes a difference in real-time between a first count value from a free running counter prior to a task executing, and a second count value after the task stops running. The task load may then be determined by using an accumulator to accumulate the difference between the first count value and the second count value over a reference interval and dividing the sum by a configurable reference interval. The individual task load computed in real-time may be used in scheduling an audio task.

  • Publication number: 20130137895
    Abstract: This invention is directed to the production of shikimic acid from Illicium griffithii fruits. The method according to the invention is particularly applicable to the isolation of shikimic acid from Illicium griffithii fruits (seeds and pericarps). Yield is 12-18% w/w. Shikimic acid is useful as raw material for the production of oseltavir (Tamiflu) used against Avian Flu. It is also reported that its triacyl derivatives can inhibit blood platelet assembling and Thrombosis by affecting the metabolism of Arachidonic acid. Hitherto known commercial methods of production of shikimic acid from the fruits of star anise (Illicium verum) and sweet gum (Liquidambar styraciflua) gives only 3-7% and 1.5% respectively. The price of shikimic acid in the international market varies from US$ 45.00 to 1000.00 per Kg depending on demand. Further as per report published at the website www.livemint.com, China Government has imposed restriction on export of shikimic acid.

  • Patent number: 8294595
    Abstract: A method and apparatus for detecting moving vehicles. A determination is made as to whether a number of vehicles are present in a video data stream received from a camera system. In response to the number of vehicles being present, a number of speed measurements for each vehicle in the number of vehicles are obtained from a radar system. A determination is made as to whether a speed of a set of vehicles in the number of vehicles exceeds a threshold. In response to a determination that the speed of the set of vehicles exceeds the threshold, a report is created for the set of the vehicles exceeding the threshold.

  • Patent number: 8051205
    Abstract: A system and method are provided for peer-to-peer distributed file storage in a network of connected clients. The method transmits data file peer-storage information from a first peer node to a network-connected backup manager. The backup manager creates a mapping plan, for mapping data file segments to a peer group, which typically includes a plurality of network-connected peer nodes. The backup manager transmits the mapping plan to the first peer node. The first peer node distributes the data file segments to the peer group in accordance with the mapping plan, for storage in tangible memory media. Typically, the first peer node accepts a data file and encrypts the data file. In one aspect, the backup manager creates a mapping plan for distributing (n+x) erasure-coded segments. After receipt of the mapping plan, the first peer node creates the (n+x) erasure coded file segments in preparation for distribution.
