  • Publication number: 20040044704
    Abstract: A system for synchronizing distributed stored documents includes a core-node (110), a plurality of branch-nodes (120, 130), and a network (140) connecting the core-node with the branch-nodes. Each branch-node includes: a branch-database server (123, 133) for storing a summary of all distributed stored documents, wherein the summary can be updated in accordance with a sync message received from the core-node; and a branch-FTP (File Transfer Protocol) server for storing the distributed stored documents, the branch-FTP server having the function of exchanging documents with the core-node. The core-node includes a core-database server (113), a core-FTP server (309), and an application server (310). The core-database server stores a summary of all distributed stored documents. The core-FTP server is used for storing the distributed stored documents. The application server comprises a sync controlling module (313) that controls data exchange between the core-FTP server and the branch-FTP servers.

  • Patent number: 6368643
    Abstract: The yeast, Saccharomyces boulardii, has been used to invent a non-toxic selenium-germanium yeast product. Culture growth conditions can influence the biosorbent selenium and germanium uptake capacity. The invention involves assimilation of selenium and germanium by the yeast under optimal conditions of incubation time, biomass concentration, reaction pH, reaction medium, and feed rate. This yeast can assimilate higher intracellular selenium and germanium by either a one-step continuous feed-batch fermentation or a two-step continuous and semi-continuous feed-batch fermentation. The invention additionally involves the novel germanium and selenium-containing yeast.

  • Publication number: 20010000028
    Abstract: Nonalcoholic steatohepatitis (NASH) is a disease of the liver characterized by inflammation and damage to the liver cells. Typically, steatohepatitis involves inflammation of the liver related to fat accumulation, and mimics alcoholic hepatitis but is observed in patients who seldom or never consume alcohol. Nonalcoholic steatohepatitis can lead to serious liver damage, and ultimately cirrhosis. The present invention provides methods and compositions useful for the treatment or alleviation of nonalcoholic steatohepatitis and the pharmaceutical formulations for their administration to a human. Specifically, compositions comprised of lecithin, antioxidants and vitamin B complex are administered parenterally, most preferably by oral administration. Specific therapeutic formulations include admixtures of these compounds and specific dosage formulations include daily oral administrations of these compounds in tablet or powder forms.

  • Patent number: 6043999
    Abstract: A digital control in line angle coordinates for a regulated power input device in which the line angle (.epsilon.) is determined from measured line voltages (U1M, U2M) by means of a coordinate transformation of the rotary field, in Cartesian coordinates and subsequent arctan calculation (ATAN). From this, under circumstances of a heavily disturbed line angle (.epsilon.) the line frequency is computed. In this, under circumstances, the strongly varying frequency information is limited to a plausible band of variations before the frequency is filtered and a relatively smooth running line angle (.epsilon.) can be calculated therefrom. In order to avoid an erroneous integration, the calculated line angle integrator is set at every phase-zero-crossing to the corresponding angle value. With this line angle (.epsilon.
