Abstract: Vitamin E TPGS/drug compositions and methods are provided which obviate the need for surfactants or non-evaporated co-solvents because the active drug component is dissolved directly into Vitamin E TPGS to form a true molecular solution-not an emulsion or a micro-emulsion. The invention provides a slowly dissolving TPGS/Drug matrix that absorbs gastrointestinal fluid into the matrix at the dosage form/fluid interface, where a gel-like liquid crystal is formed. This gel front forms a liquid crystal boundary where drug dissolution is highest. At this liquid crystal/GI fluid boundary, a synchronization takes place in which the rate of formation of liquid crystals equals the dissolution rate of liquid crystals at the water interface, thereby giving controlled order release of the drug into the GI tract. The rate of dissolution is also controlled by the geometry of the dosage form. The solid Vitamin E TPGS/drug matrices of the invention can be solidified and compressed into tablets or filled into capsules, with other excipients, binders and/or fillers. The solid TPGS/drug solution of the invention also can be made into an immediate release liquid formulation upon addition of water, or into a controlled release system solid tablet by the use of impermeable or semi-permeable barriers or coatings surrounding portions of the tablet.

Abstract: A process for thin film formation is provided which comprises a step of separation of a substrate constituted of a nonporous Si layer, a porous Si layer formed thereon, and a less porous Si layer formed further thereon into the nonporous Si layer and the less porous Si layer at the porous Si layer, wherein the separation is caused by projecting a laser beam through the side face of the substrate. From the separated substrate, an SOI substrate is prepared, and the non porous Si layer is recycled to the SOI substrate production process. This SOI substrate production process saves the consumption of the material and lowers the production cost. The substrates are separated definitely. A process for producing a photoelectric transducing apparatus such as solar cells with material saving and low cost is also provided in which the porous layer is separated definitely without strong adhesion between the substrate and a jig. <IMAGE>

Abstract: Exhaust gas recirculation and selective catalytic reduction with urea or other NOx- reducing reagent are employed to enable good fuel economy and low emissions from diesel and lean-burn gasoline engines. EGR is operated at low-load, as well as when problems are experienced with reagent supply or the SCR unit. The SCR is run at its optimum operating conditions of normal to high load, supplanting the need for EGR. The net effect is a circumvention of the known tradeoff between NOx and poor fuel economy. The novel application of SCR and EGR in combination will provide engines that meet low emissions requirements with existing technology.

Abstract: The invention concerns a 5-aminolevulinic acid ester (E-ALA) solution for producing a pharmaceutical preparation useful for diagnosing and/or treating tissue and/or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, in the case diagnosis, by detection of fluorescent protoporphyrin IX (Pp1X). The E-ALA concentration in the solution is less than 1% and ranges between 0.01% and 0.5%. The low E-ALA concentration in the solution increases Pp1X synthesis and homogenises its distribution in the cell layers while highly reducing the secondary toxicity for the treated cells.

Abstract: The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention, the feedstock is fed into a fluidized-bed reactor, wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor and the regenerator comprise risers having an axially annular cross section and being equipped with multi-inlet cyclones for the separation of particulate matter. By means of the invention, it is possible to producer pyrolysis oil, the quality of which is higher than that of oil produced with the processes of the prior art. The incorporation of multi-inlet cyclones into the reactor configuration reduces gas velocities, reduces the physical size of the cyclone and shortens the residence time of gases in the cyclone.

Abstract: A device provides an indication of a condition of an ear by combining measurements of temperature in the ear, acoustic reflectance of the ear, and/or a characteristic of any fluid in the ear. Any two of these measurements may be combined in the same device to provide improved diagnostic information. For example, chemical sensing of fluid may be combined with acoustic reflectometry or temperature sensing, or both, to provide improved diagnosis of ear pathologies. Acoustic reflectometry also may be combined with temperature sensing. Chemical sensing determines a characteristic of the fluid, such as whether a bacterium or a virus is present. The device may provide diagnostic information from sensed characteristics of the fluid, measured acoustic reflectance and/or measured temperature to indicate the risk of an ear infection. For example, the device may determine if any fluid present is infected. The device also may identify bacteria in the fluid. The temperature sensor also may be used to improve alignment between the device and the tympanic membrane, thus improving the accuracy of measurements.
