Abstract:
An instrumented pig comprises a foam body having an outer surface and an inner cavity in which, in use, is located a sealed unit housing at least a part of a parameter measurement apparatus configured to measure at least one parameter from which the extent of deflection of the outer surface of the foam body may be derived, the sealed unit including at least one sensor configured to generate an output signal representative of the at least one measured parameter.
Abstract:
A method is provided of forming a light sensing array for use in a light sensor. The method comprises tiling a plurality of individual light sensing elements on a carrier, each element having a notch formed in an edge thereof, the notch being adapted to provide space, when the elements are tiled together, for an electrical connection to be made between the carrier and a surface of the element arranged to faced away from the carrier. Each element may comprise Silicon Photomultiplier (SPM) circuitry.

Abstract:
Compositions and methods for enhancing paracellular permeability at an absorption site in a subject are disclosed. The method includes: (a) administering an effective amount of a phospholipase C inhibitor to a subject at a time in which enhanced paracellular permeability is desired; and (b) enhancing paracellular permaeability in the subject at the the absorption site through the administering of the effective amount of the phospholipase C inhibitor. The disclosed compositions and methods provide enhanced absorption of a hydrophilic drug in a subject.
Abstract:
A transport container (10) defining a storage volume (11) for particulate matter having an outlet, means for pressurising (18) the storage volume (11) and means for aerating (16, 17) the particulate matter therein and a discharge valve (23) for regulating the flow of the aerated particulate matter through the outlet, wherein the container (10) further comprises a sensor (50) for detecting vibrations during discharge of said particulate matter and for thereby producing a signal indicating that the discharge valve (23) should be closed so as to prevent over-pressurisation of a receptacle (40) receiving said particulate matter.
Abstract:
A measuring device for determining the thickness of a non-homogenous medium such as the thickness or a road structure. The device includes a radar transmitter Tx and two spaced receivers Rx1, Rx2. Information on the timing of the transmitted signal as well as the signals received by the two receivers is used to calculate the material thickness whilst eliminating signal drift.
Abstract:
An exhaust fan is driven by a water turbine. The water turbine is connected between the water supply and point of use so that when the water is used, e.g., shower, bath, toilet, the fan is driven by the water turbine.
