Abstract: A method for producing an L-amino acid, such as L-histidine, L-threonine, L-lysine, L-glutamic acid, and L-tryptophan, using bacterium belonging to the genus Escherichia which has increased expression of genes, such as those of the xylABFGHR locus, which encode the xylose utilization enzymes, is disclosed. The method includes cultivating the L-amino acid producing bacterium in a culture medium containing xylose, and collecting the L-amino acid from the culture medium.

Abstract: A stator heat shield (6) for a gas turbine (1) includes an outside (11) which in the installed state faces a hot gas path (9) of the gas turbine (1), and an inside (12) facing away from the outside (11). A plurality of ribs (13) are formed on the inside (12) and extend axially in the installed state with regard to an axis of rotation (8) of a rotor (3) of the gas turbine (1) and, in the circumferential direction, are spaced a distance apart from one another. At least one baffle plate (14) is arranged on the inside (12) and is in contact with the ribs (13). At least one groove (16) is designed in an end face (15) bordering the stator heat shield (6) in the circumferential direction, into which at least one sealing element (18) can be inserted. A plurality of bores (19) are included, each opening at a distance from the groove (16) in the direction of the outside (11) at the inside (12) at one end and on the end face (15) at the other end and arranged a distance apart from one another in the axial direction.

Abstract: A gas turbine airfoil (1) includes a pressure sidewall (15) and a suction sidewall (16), extending from a root to a tip and from a leading edge region to a trailing edge and having at least one cooling passage between the pressure sidewall (15) and the suction sidewall (16) for cooling air to pass through and cool the airfoil from within. One or several of the cooling passages (3) extend along the leading edge of the airfoil (1) and several film cooling holes (1,2) extend from the internal cooling passages (3) along the leading edge region to the outer surface of the leading edge region. The film cooling holes (1,2) each have a shape that is diffused in a radial outward direction of the leading edge of the airfoil (1) at least over a part of the length of the film cooling hole (1,2).

Abstract: A system and methods useful for treating morbid obesity include the installation of a stenosis into an artery of a morbidly obese patient, the artery selected to be one that supplies blood to the small intestine of the patient.

Abstract: A DNA encoding a variant of a protein having a loop region and six hydrophobic helixes which is involved in excretion of L-lysine to outside of a cell is described, wherein the DNA encodes a mutant protein which does not contain the loop region that is present in the wild-type protein. The mutant protein facilitates excretion of L-lysine, L-arginine, or both to the outside of the cell of a methanol assimilating bacterium when the DNA is introduced into the bacterium. Specifically, lysE24 is introduced into a methanol assimilating bacterium such as Methylophilus bacteria which results in improved L-amino acid productivity, especially production of L-lysine and L-arginine.

Abstract: An optical modulator component 2 has a substrate 4 for modulation made of an electro-optical material and having a joining face 4b; an optical waveguide 6 provided in or on the substrate 4 and having at least one pair of branched portions 6c; and a radio-frequency interaction portion 11 applying a voltage on the respective branched portions 6c to modulate light propagating through the branched portions. The optical waveguide 6 has end faces 15A, 15B, 15C and 15D present on the joining face 4b of the substrate 4 for modulation.

Abstract: A process for the stereoselective decarboxylation of malonic acid derivatives with mutated decarboxylases is disclosed.

Abstract: Before a buffer layer deposition step P5, a pre-rinse step P4 is provided to remove deposits deposited on the surface of a CIS-based light absorbing layer 3D. Thus, the disturbing factors of the formation reaction of the buffer layer are removed, thereby to improve the coverage of the buffer layer, and to hold the transparency thereof. In addition, a rinse step P6 is provided after the step P5. Thus, the colloidal solid matter remaining on the buffer layer surface is cleaned and removed with a rinse solution, thereby to hold the high resistivity. The rinse solution from a second rinse tank of the step P6 is re-used. After the step P6, a draining/drying step P7 is provided. After drying, an n-type window layer (transparent conductive film) is deposited.

Abstract: An optical modulator 24 has a supporting substrate 5, a modulating substrate 11 made of an electro-optical material, an optical waveguide 12 provided on the side of a first main surface 30 of the modulating substrate 11, and an adhesion layer 6 adhering a second main surface 31 of the modulating substrate 11 onto the supporting substrate 5. The modulating substrate 11 has a high-frequency interaction portion 11c applying a voltage on the optical waveguide 12 to modulate propagating light, an incident portion 11a inputting light to the optical waveguide, and an outgoing portion 11b outputting light from the optical waveguide. The high-frequency interaction portion 11c is recessed on the first main surface 30 of the modulating substrate 11 with respect to the incident and outgoing portions 11a and 11b. The high-frequency interaction portion 11c has a thickness smaller than the those of the incident and outgoing portions 11a and 11b.

Abstract: A burner (23) for operating a heat generator includes a swirler (2) for a combustion air flow (9), and also devices (7, 12) for injecting at least one fuel into the combustion air flow (9), wherein a mixing path (3) is arranged downstream of the swirler (2), and wherein at least one nozzle (20) for feeding liquid pilot fuel is arranged in the region radially outside the discharge opening of the mixing path (3) of the burner. With such a burner, an operating mode which is as pollutant-free and overheating-free as possible can be enabled even at low load and under transient conditions if the at least one nozzle (20) is arranged in a burner front plate (32), wherein at least one discharge opening (15), through which the pilot fuel discharges into the combustion chamber (16), is provided in a front face (34) of the burner front plate (32), which is arranged essentially parallel to a combustion chamber rear wall (28).

Abstract: A mutant tyrosine repressor that does not require tyrosine to induce expression of tyrosine phenol-lyase gene is obtained by introducing a mutation into a tyrosine repressor. A microorganism which is able to express large amounts of tyrosine phenol-lyase is obtained by introducing the mutant tyrosine repressor into the microorganism. The microorganism is useful for producing L-DOPA.
