  • Publication number: 20140143156
    Abstract: Methods, devices, and systems are provided in a multi-level computer architecture which provides improved capabilities for managing courseware and other content in a shared use operating environment such as a computer network. In particular, the invention provides a commercial networked instruction content delivery method and system which does not exclude synchronous sharing but is focused on asynchronous sharing. Security means in the architecture provide content property holders with the ability to know how many minutes of use an individual made of licensed material and with increased certainty that their material cannot be used, copied, or sold in usable form unless and until a user site is connected or reconnected to a minute-by-minute counter which is located off the premises of the user. This security link helps protect software and other works which are being sold or licensed to an individual, organization, or entity, and creates income opportunities for owners of such content.

  • Patent number: 8563677
    Abstract: A stable catalyst solution suitable for catalyzing the polycondensation of reactants to make polyester polymers comprising: (i) M, wherein M is represented by an alkaline earth metal or alkali metal and (ii) aluminum metal and (iii) a polyhydroxyl solvent having at least 3 carbon atoms and at least two primary hydroxyl groups, the longest carbon chain being a hydrocarbon; such as 1,3-propane diol, 1,4-butane diol, 1,5-pentane diol, or combinations thereof, wherein the molar ratio of M:Al ranges from 0.75:1 to less than 1.5:1. The catalyst solution is desirably a solution which does not precipitate upon standing over a period of at least one week at room temperature (25° C.-40° C.), even at molar ratios of M:Al approaching 1:1. There is also provided a method for the manufacture of the solution, its feed to and use in the manufacture of a polyester polymer, and polyester polymers obtained by combining certain ingredients or containing the residues of these ingredients in the composition.

  • Publication number: 20090181443
    Abstract: Isolated novel and purified and characterized phospholipase A2, referred to herein as calcium-independent phospholipase A2zeta (iPLA2zeta) having SEQ. ID. NO: 2 (See FIG. 1), and nucleic acid sequence (SEQ. ID. NO: 4), and calcium-independent phospholipase A2eta (iPLA2eta) having SEQ. ID. NO: 3 (See FIG. 1), and nucleic acid sequences (SEQ. ID. NO: 5). For the first time herein, these novel enzymes have been isolated and characterized and are involved in the catalysis, synthesis and hydrolysis of lipids in a living mammalian cell. Moreover, these enzymes iPLA2zeta and iPLA2eta through the process of transesterification can catalyze the net anabolic synthesis of triglycerides through a variety of metabolic precursors (e.g. monoacylglycerol, diacylglycerol and acyl CoA).
