Abstract: A photoplethysmograph device includes a light source for illuminating a target object. A modulator drives the light source such that the output intensity varies as a function of a modulation signal at a modulation frequency. A detector receives light from the target object and generates an electrical output as a function of the intensity of received light. A demodulator with a local oscillator receives the detector output and produces a demodulated output, insensitive to any phase difference between the modulation signal and the oscillator, indicative of blood volume as a function of time and/or blood composition. A number of demodulators may be provided to derive signals from multiple light sources of different wavelengths, or from an array of detectors. The plethysmograph may operate in a transmission mode or a reflectance mode. When in a reflectance mode, the device may use the green part of the optical spectrum and may use polarising filters.

Abstract: A method for separating hydrocarbon content from a hydrocarbon contaminated matrix. The method includes controlling water content of a feed material having the hydrocarbon contaminated matrix; continuously conveying the feed material into a treatment cavity; exposing the feed material in a treatment area of the treatment cavity to microwave radiation arranged to cause rapid heating of at least a portion of the water content to form steam, wherein the rapid steam formation results in thermal desorption of at least a portion of the hydrocarbon content from the matrix; and continuously removing the treated matrix from the treatment cavity.

Abstract: A method of double crossover homologous recombination in a host cell comprising: a first homologous recombination event between a donor DNA molecule comprising a first element of a selectable allele and an acceptor DNA molecule comprising a second element of the selectable allele in the host cell, thereby to form a product of the first homologous recombination event in the host cell; and a second homologous recombination event within the product of the first homologous recombination event, thereby to form a product of the second homologous recombination event in the host cell which confers a selectable phenotype on the host cell, wherein the selectable phenotype arises following and in dependency on the formation of a selectable allele from the first and second elements of the selectable allele.

Abstract: Ways of applying microwaves to feedstock to be processed are disclosed. One embodiment relates to heating inter-layer water in vermiculite to expand the vermiculite. Another embodiment relates to heating water in oil-contaminated materials and waste products, such as drilling cuttings, contaminated soils and certain types of animal by-products, to drive out oil. In some embodiments a microwave tunnel applicator has the microwaves applied from beneath the feedstock.

Abstract: A generator structure has alternating linear regions which are respectively relatively absorbing and relatively non-absorbing. When the structure is illuminated, the spatial contrast in the absorption created by the characteristics of the regions gives rise to mechanical effects within the workpiece, such as localized heating. This results in ultrasound being created to propagate through the workpiece.

Abstract: A method for testing the mechanical properties of a specimen. The specimen is generally characterized by a first contact surface and a second contact surface spaced apart from and opposing the first contact surface. The method involves applying forces to the contact surfaces of the specimen to deform the specimen over a period of time. The response of the specimen to the forces is then measured over time. A spatial distance between the contact surfaces is defined such that the equivalent gauge length of the specimen is greater than the distance between the contact surfaces.

Abstract: One aspect of the present invention relates to a readily water-dispersible particulate composition comprising by weight of dry matter at least 10% of xanthan gum and not more than 60% of starch, said composition being characterized in that the xanthan gum present in the composition can be dispersed completely within 2 minutes in distilled water of 25° C. at a concentration of 0.7% based on the dry weight of xanthan. The particulate xanthan gum compositions of the present invention exhibit unique viscosity enhancing properties that are dependent on the electrolyte levels of the aqueous environment in which they are applied. The favorable properties of the xanthan compositions according to the invention can be realized without resorting to chemical modification of the xanthan gum. The xanthan compositions according to the present invention can be applied advantageously in e.g. food products and oil drilling fluids.

Abstract: Non-leguminous crops, e.g. wheat, maize and rice, do not form nodules and are dependant for their nutrition on fixed nitrogen from the soil, or from chemical/nitrogenous fertilizers. The present invention provides non-leguminous plants and leguminous plants, including legumes that fail to nodulate with Rhizobia, with bacteria that enable them to fix nitrogen endophytically. Therefore, the plants contain nitrogen fixing bacteria the bacteria being located intracellularly in living plant cells.

Abstract: A sample 10 is measured by generating ultrasound at 12, for example by using a laser 22 and spatial light modulator 26. The ultrasound is detected at 16, for example by optical beam deflection techniques. A characteristic of the generation at 12 is swept across a range of values to vary the efficiency of generation of ultrasound. The value of the characteristic, which corresponds with the peak amplitude detected at 16, is identified to provide a measure of the acoustic velocity at the region 12. The method is executed at a plurality of sites 12, 20 to provide a set of spatially resolved measurements of the sample 10. This allows an image of the sample to be created.
