Abstract:
A method of and apparatus for obtaining radiation transmission data and especially an image of an object which involves providing a radiation source such as an x-ray or gamma-ray source and a radiation detector system such as an x-ray or gamma-ray detection system spaced therefrom to define a scanning zone therebetween, the detector system being capable of detecting and collecting spectroscopically resolvable information about incident radiation; collecting a dataset of information about radiationincident at the detector and hence transmissivity of an object in the scanning zone at at least one and preferably a plurality of scanning positions from radiation transmitted through the object and received at the detector system; resolving each such dataset spectroscopically across a plurality of frequency bands within the spectrum of the source; wherein at least one of the said plurality of frequency bands corresponds to a characteristically scattered wavelength of a target species to be identified, andwherein the absence of or substantial reduction in a transmitted signal intensity at the frequency band is interpreted as the presence of the said target species. The resolved data is preferably resolved as one or more images.
Abstract:
Organic compounds showing the ability to inhibit viral glycoprotein (GP)-mediated entry of a filovirus into a host cell are disclosed. The disclosed filovirus entry inhibitor compounds are useful for treating, preventing, or reducing the spread of infections by filovirus including the type species Marburg virus (MARV) and Ebola virus (EBOV). Preferred inhibitors of the invention provide therapeutic agents for combating the Ivory Coast, Sudan, Zaire, Bundibugyo, and Reston Ebola virus strains.
Abstract:
A tracking device for tracking with a radioactive material, a container including such a device, a system using such devices, and a tracking method are described. The device has a radiation detector (10) associatable with a radioactive material (14) adapted to be placed in use within a container (1) defining a radiation-shielded enclosure (7) for containing a radioactive material, to detect radiation activity from the material (14); a RF identification module (12) associatable with the container (1), comprising a data register to store a unique product identification code, a processor with a data transfer link (11) to each of the radiation detector (10) and data register to receive and process a live data stream of activity data from the detector (10) and associate this with the unique product identification code in a processed data packet, and an antenna (13) to enable transmission of a data item comprising both the unique product identification code and processed activity data to a remote data capture means (16), at least the antenna (13) being adapted to sit outside the radiation-shielded enclosure.

Abstract:
A method and apparatus for obtaining radiation transmission data comprising information about the composition of an object are described. The principle involves providing a radiation source such as an x-ray or gamma-ray source and a radiation detector system such as an x-ray or gamma-ray detector system, the detector system being capable of detecting and collecting spectroscopically resolvable information about incident radiation; collecting a dataset of information about radiation incident at the detector; resolving the dataset spectroscopically.across a plurality of frequency bands within the spectrum of the source to produce a corresponding plurality of frequency-specific datasets; determining an intensity ratio for at least one pair of frequency specific datasets; using this to identify materials present.
Abstract:
Apparatus for vapour phase growing of crystals having a single multi-zone heater arranged to heat a heated zone to give a predetermined temperature profile along the length of the heated zone. A generally U-shaped tube having a first limb, a second limb, and a linkage connecting the first alid second limbs is located on the heated zone. The first limb contains a source material. The second limb supports a seed such that the source material and seed are spaced longitudinally within the heated zone to provide a predetermined temperature differential between the source and seed. The crystal is grown on the seed.
