  • Publication number: 20150011525
    Abstract: A stable ternary solid dispersion composition with enhanced physical stability and/or bioavailability comprising: (a) about 1% wt. to about 50% wt. of one or more poorly soluble active pharmaceutical ingredient (API) which belongs to Biopharmaceutics Classification System (BCS) class II and/or IV; (b) about 11% wt. to about 50% wt. of at least one water-soluble polymer; and (c) about 20% wt. to about 99% wt. of crosslinked polyvinylpyrrolidone (crospovidone, a water-insoluble polymer). The solid dispersion is capable of inhibiting crystallization of API in solid state and/or aqueous gastrointestinal tract (GIT) medium. Also disclosed is a method of preparation of such solid dispersion composition by fusion or solvent or fusion-solvent method.

  • Publication number: 20140100797
    Abstract: According to one embodiment, a system for determining hydrocarbon production may be disclosed. The system may include one or more processors and a memory comprising logic. The memory comprising logic may be operable to determine an accumulated unit density of a reservoir unit from a density log. The memory comprising logic may be further operable to determine a thickness of the reservoir unit and determine a density footage of the reservoir unit based on the accumulated density and the thickness. The memory comprising logic may also be operable to generate a total organic carbon content per density footage based on the density footage. In accordance with certain embodiments, the memory comprising logic may be operable to determine a potential production of hydrocarbons based on the total organic carbon content per density footage of the reservoir unit.
