Abstract: The present invention relates to a method of increasing the volatile organic compound (VOC) emissions in a ruminant, said method comprising the administration of a methane inhibitor to said ruminant. The increase in the VOC emissions can be used for monitoring and/or quantifying the reduction of methane emanating from the digestive activities of the ruminant affected by the feeding of said methane inhibitor.

Abstract: A method of navigating visual content includes establishing an interface template including a viewport; obtaining visual content data; identifying at least one focusable element in the visual content data; presenting a first portion of visual content in the viewport on a display device, wherein the visual content is based at least partially on the visual content data; indicating a first focusable element in the viewport with a visual indicator; and responsive to a user input, scrolling the visual content in the viewport when a second focusable element of the visual content is not present in the viewport in a navigation direction of the user input.

Abstract: A method of determining if a subject has a mild cognitive impairment (MCI) or Alzheimer's Disease, the method comprising measuring the concentration of one or more VOCs in an exhaled sample from a subject, and comparing the concentration with a reference concentration, I.

Abstract: A screening method for confirming that a subject does not have a Group B Streptococcus (GBS) infection, the method comprising: determining if a GBS-volatile organic compound (VOCs) is not present in a sample that has been taken from the genital mucosa of the subject, wherein if a GBS-VOC is not present in the sample, the subject does not have a Group B Streptococcus infection. A method of diagnosing that a subject has a Group B Streptococcus (GBS) infection, the method comprising: determining if a GBS-volatile organic compound (VOCs) is present in a sample that has been taken from the genital mucosa of the subject, wherein if a GBS-VOC is present in the sample, the subject has a Group B Streptococcus infection.

Abstract: The invention relates to diagnostic devices, which are capable of characterising gases and other volatile organic compounds (VOCs) present in the gastrointestinal tract, for diagnosing diseases. The invention extends to apparatuses for use in the in vivo detection and characterisation of gases and VOCs, and to methods for diagnosing diseases.

Abstract: A method of manufacturing a semiconductor device, wherein the method comprises applying a first layer comprising silicon to a second layer comprising silicon carbide, wherein an interface is defined between the first and second layers; and oxidising sonic or all of the first layer.

Abstract: A gas-sensing semiconductor device is fabricated on a silicon substrate having a thin silicon oxide insulating layer in which a resistive heater made of a CMOS compatible high temperature metal is embedded. The high temperature metal is tungsten. The device includes at least one sensing area provided with a gas-sensitive layer separated from the heater by an insulating layer. As one of the final fabrication steps, the substrate is back-etched so as to form a thin membrane in the sensing area. Except for the back-etch and the gas-sensitive layer formation, that are carried out post-CMOS, all other layers, including the tungsten resistive heater, are made using a CMOS process employing tungsten metallisation. The device can be monolithically integrated with the drive, control and transducing circuitry using low cost CMOS processing. The heater, the insulating layer and other layers are made within the CMOS sequence and they do not require extra masks or processing.
