Abstract: A method of fabricating a bone substitute material comprises the steps of providing a foam material (3) having an open cell structure, distorting the shape of the foam material (3) and holding the material in a distorted shape, coating the walls of the cells of the foam material with a ceramic slip (5), removing the foam material, and sintering the ceramic slip to form a bone substitute material that is approximately a positive image of the distorted foam material (3). In another method, a granular bone material is formed from a multiplicity of pieces of foam that are not distorted.

Abstract: A formulation for use as a bactericidal agent in the human or animal digestive system includes xanthine oxidoreductase. The formulation may especially be in the form of a formula feed formulation or enteral feed formulation for administration to a human or animal. The formulation is capable of functioning as a “natural antibiotic” to prevent or reduce bacterial infection within the gut, especially the neonatal gut.

Abstract: A method for controlling endosperm size and development in plants. The method employs nucleic acid constructs encoding proteins involved in genomic imprinting, in the production of transgenic plants. The nucleic acid constructs can be used in the production of transgenic plants to affect interspecific hybridisation.

Abstract: A method of image compression includes significance switching of DCT coefficients in block-based embedded DCT procedures. Bitwise digitized DCT coefficients are passed through successive significance sweeps of the whole image from the most significant down to the least significant coefficient bit planes. With each new sweep, newly significant coefficients may appear within a block, and block-masking is used to transmit the addresses of those newly significant coefficients. An off-mask may also be used. The invention further relates to a hardware or software-based image encoder.

Abstract: An object-oriented video system is implemented as a two layer object model in a software-only video compressor. Quadtree decomposition on an error metric between the input and transmitted images directs the coder towards a foreground layer of active image fragments. A rate buffering system limits the bandwidth by transmitting only the foreground blocks which most improve the image and are above some error threshold. A high fidelity background layer is identified and communicated to the decoder, which can be used to redraw background fragments as foreground objects move across them. Blocks can be coded by various methods, such as fractal transforms or truncated DCTs. The system can be implemented in RISC processors without the need for dedicated hardware. It is suitable for low bit rate applications with slowly varying backgrounds, such as personal video communications over packet networks, or closed circuit TV surveillance.

Abstract: A system for detecting a fault in a power line (1) includes, in the power line (1), a first circuit (4) capable of attenuating signals within a first frequency band, which is centered on a first frequency, substantially more than it attenuates signals outside the first frequency band, and, a second circuit (5) connected to the power line (1) on one side of the first circuit (4), the second circuit (5) being capable of extracting signals within a second frequency band that includes the first frequency. The relative levels of two signals extracted by the second circuit (5), are detected and signalled, the two signals being at respective frequencies which the first circuit is capable of attenuating by different relative amounts.

Abstract: A localized clean air system for operating theaters and a method of supplying clean air to a localized region in such situations. A fan is connected to a delivery head, which has an outlet for directing inlet clean air to the localized region in a particular pattern. A streamlined body is positioned in the outlet so that, in use, the clean air flows around the body and is modified thereby to form, immediately downstream of the body, an inner region of low velocity air encircled by an outer region of higher velocity air. Preferably, the streamlined body is symmetrical about its axis and is aligned with the clean air flow, for instance by being centrally positioned in the air outlet. The streamlined body preferably comprises a rounded head and a tapered tail. A diffuser is disposed in the clean air flow upstream of the streamlined body to minimize turbulence in the air flow.
