摘要:
A multilayer window structure for a solar cell comprises one or more layers where the bottom layer has an intrinsic material lattice spacing that is substantially the same as the emitter in the plane perpendicular to the direction of epitaxial growth. One or more upper layers of the window structure has progressively higher band gaps than the bottom layer and has intrinsic material lattice spacing is substantially different than the emitter intrinsic material lattice spacing.

A plate with integrated design for sauces includes a plate well, a lip, an outer base, a plurality of central bases, at least one design indentation, and a design indentation border. The lip is positioned around the plate well, and the outer base and the plurality of central bases are positioned with the plate well opposite from the lip. The at least one design indentation is positioned on the plate well and provides a separate area for the sauces. The design indentation border that provides a barrier between a food surface of the plate well and a top surface of the at least one design indentation is positioned around the at least one design indentation. The plate with integrated design for sauces allows food items to be served on the food surface while keeping the sauces within the at least one design indentation.

摘要:
Photovoltaic cells with one or more subcells are provided with a wide band gap, pseudomorphic window layer of at least 15 nm in thickness and with an intrinsic material lattice constant that differs by at least 1% from an adjacent emitter layer. This window layer has a higher band gap than a window layer with substantially the same intrinsic material lattice constant as the adjacent emitter layer, which increases the light transmission through the window, thereby increasing the current generation in the solar cell. The quality of being pseudomorphic material preserves a good interface between the window and the emitter, reducing the minority carrier surface recombination velocity. A method is provided for building a wide band gap, pseudomorphic window layer of a photovoltaic cell that has an intrinsic material lattice constant that differs by at least 1% from the adjacent emitter layer.

A dispenser (1) for a pack of wet wipes, has a stiff plastics material body (2) with a peripheral mounting flange (3) for attachment to a sidewall of a pack of wipes. A tear-open closure (4) is integrally formed with the body (2). A portion of a periphery of the closure (4) is tearable away from the body (2) to leave the closure (4) attached to the body (2) by a hinge (5). The closure (4) is mounted at an opening in the body (2) across which is etched a silicone membrane having a circular dispensing opening through which wipes are dispensed from a flow-wrap plastics pack of wipes on which the dispenser (1) is mounted.
摘要:
This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.

A lattice-matched solar cell having a dilute nitride-based sub-cell has exponential doping to thereby control current-carrying capacity of the solar cell. Specifically a solar cell with at least one dilute nitride sub-cell that has a variably doped base or emitter is disclosed. In one embodiment, a lattice matched multi junction solar cell has an upper sub-cell, a middle sub-cell and a lower dilute nitride sub-cell, the lower dilute nitride sub-cell having doping in the base and/or the emitter that is at least partially exponentially doped so as to improve its solar cell performance characteristics. In construction, the dilute nitride sub-cell may have the lowest bandgap and be lattice matched to a substrate, the middle cell typically has a higher bandgap than the dilute nitride sub-cell while it is lattice matched to the dilute nitride sub-cell. The upper sub-cell typically has the highest bandgap and is lattice matched to the adjacent sub-cell. In further embodiments, a multi junction solar cell according to the invention may comprise four, five or more sub-cells in which the one or more sub-cells may each comprise exponentially doped dilute nitride alloys.

The present invention relates to modulators of the Neuregulin (NRG) family, particularly NRG1 and more particularly NRG1β, and most particularly NRG1β1. The present invention also relates to the use of such modulators to inhibit goblet cell hyperplasia and therefore also relates to the use of such modulators in the treatment or prevention of human diseases and disorders featuring pathological mucus production such as COPD, CF, chronic bronchitis and asthma.

The present invention relates to the use of a GPR4 inhibitor for the manufacture of a medicament for the inhibition of angiogenesis, for instance for the inhibition of tumour growth in the treatment of cancer. In a preferred embodiment, said inhibitor is a siRNA, preferably double-stranded.In addition, the present invention further encompasses non-human animals wherein the GPR4 has been inactivated, for instance a knock-out mouse lacking GPR4, and the use of said animals as an experimental model for angiogenesis and for screening for compounds modulating angiogenesis.
