Abstract: Disclosed is an assay device comprising liquid transport means adapted to take up a liquid sample and conduct the liquid to an analyte detection region operable to provide a test signal indicative of the presence and/or amount of an analyte in the liquid sample; the assay device further comprising a sample presence signal generation means, which is not generated by means of an immunoreaction. This sample presence signal generation means can comprise a colored portion, which is overlaid by a material (e.g. nitrocellulose) that is opaque, when dry, and translucent or transparent, when wet, to allow the colored portion to become visible to the user. In another embodiment the signal generation means comprises a color changing material which under-goes a change in its visible properties upon wetting (e.g. pH indication). A third embodiment uses a mobilizable detectable which, when wetted by the sample, is carried along resulting in a streaked line parallel with the flow direction.

Abstract: A phytochemical composition for use as a veterinary dietary supplement comprising alpha linolenic acid (ALA) and up to 10% gamma linolenic acid (GLA). Preferably the ALA source is flax seed oil and GLA is sourced from borage oil.

Abstract: This invention relates to the treatment of wastes including sewage, solids which may include both combustible and incombustible solids, and optionally waste fuel such as oil. The invention provides a method and plant for treating wastes in which solids are converted to an incineratable form which, in a first embodiment, is incinerated with the sewage solids obtained by separating the sewage into a sewage solids component and a clarified waste water component together with additional fuel if necessary, at least a part of said clarified waste water component being optionally incinerated to control temperatures during incineration, and any remaining waste water being disinfected. In a second embodiment the incineratable material is incinerated with the sewage together with the waste fuel and additional fuel if necessary.
