The invention relates to methods for culturing human embryonic stem cells by culturing the stem cells in an environment essentially free of mammalian fetal serum and in a stem cell culture medium including amino acids, vitamins, salts, minerals, transferring, insulin, albumin, and a fibroblast growth factor that is supplied from a source other than just a feeder layer the medium. Also disclosed are compositions capable of supporting the culture and proliferation of human embryonic stem cells without the need for feeder cells or for exposure of the medium to feeder cells.

There is provided an LC resonance type oscillation circuit with a wide frequency variable range with a small variation of Q and capable of reducing a chip size due to no external parts required, and a communication semiconductor circuit device (high-frequency IC) having the oscillation circuit. In the LC resonance type oscillation circuit, a capacitance element and a switch element are connected in parallel between both terminals of a secondary side inductance element which is placed facing an inductance element constituting the LC resonance circuit and is connected by mutual induction to the inductance element. It is designed so that an equivalent inductance increases as the capacitance element is connected between the both terminals of the secondary side inductance element in a state where the switch element is turned OFF, and that the equivalent inductance decreases as the both terminals of the secondary side inductance element are short-circuited in a state where the switch element is turned ON.

A system for protection, control, metering, and monitoring of the delivery of electrical power is disclosed. Embodiments of the system provide input/output devices called bricks to receive analog and binary field data from primary equipment located in a power substation switchyard. The bricks are linked via fiber-optic patch cables and patch panels with one or more intelligent electronic devices (“IEDs”). In operation, the bricks convert the received binary and/or analog field data into digital signals, and transmit the digital signals synchronously to their associated IEDs using clock signals provided by each IED to the individual bricks. The bricks may accept a computer software code download from each of its master IED(s). Multiple code implementations, each tailored to the requirements of its master IED(s) can therefore co-exist on a single brick.

The application discloses a formulation and method for increasing bioavailability of an orally administered drug.

A dielectric layer (e.g., an interpoly dielectric layer) is deposited over low and high voltage devices of a peripheral memory device. The dielectric behaves as an oxidation and wet oxide etch barrier. The dielectric prevents the devices from being stripped by a wet oxide etch that can result in the exposure of the silicon corners. The exposure of a silicon corner may increase thinning of a gate oxide at the field edge. This causes variability and unreliability in the device. The dielectric is not removed from a device until the device is ready for processing. That is, the dielectric remains on a device until the growing of a gate oxide on that device has begun. This reduces the exposure of the silicon corner. Hedges that result may be removed by exposing a trench in the field oxide at the hedge.

The present invention describes a catalyst support, which is used as an inorganic carrier for a Ziegler-Nata catalyst (ZN), using a modified spray cooling method. Such a catalyst support is prepared from alcoholic solutions of (a) an inorganic compound, in which the inorganic compound is a magnesium compound and (b) an inorganic compound and one or more additives. The solutions are prepared at a temperature below 100° C., carried through a nozzle placed inside a reactor, and sprayed into droplets forming a solid precipitate, which is generally spherical, when in contact with an inert hydrocarbon solvent at low temperature. The obtained catalyst support is reacted with a titanium compound, preferably titanium tetrachloride, in order to produce an active catalyst for olefin polymerization.
