Abstract:
A field effect transistor comprising a source including a plurality of electrode projections with spaces in between. A drain includes a plurality of electrode projections each located in one of the spaces between the electrode projections of the source thereby forming a drain-source electrode connection area of alternating drain and source projections. A gate is spaced apart from the drain-source electrode area thereby forming a channel between the gate and the drain-source electrode connection area wherein the gate runs parallel to the channel. A plurality of nano-structures is located in the drain-source electrode area thereby to form an electrical connection between the electrode projections of the drain and source in the drain-source electrode connection area. The invention extends to a gas detector including a plurality of field effect transistors as described above located on a substrate.
Abstract:
An emulsion-derived particle comprises a lattice of polymeric strands cross-linked by means of a cross-linking agent, and interstitial openings adjacent and around the strands. Functional groups are provided on the lattice and proteins and/or modified proteins can react with these, thereby to be bonded to the lattice and hence immobilised.
Abstract:
A biological process for treating waste water includes introducing an algal component into the waste water. The algal component comprises Chlorella prototheocoides or a combination of Chlorella prototheocoides and Chlorella vulgaris. While maintaining passive conditions in the waste water, the algal component is allowed to extract at least one nutrient from the waste water, thereby to phycoremediate the waste water.
Abstract:
The invention provides a method of printing, onto a substrate (12), an array (14) of spots of reagent compositions for use in a chemical and/or biochemical analysis. The method includes displacing an array of reagent composition containing capillary tubes (22) arranged alongside one another from an inoperative position to an operative position in which open ends of the capillary tubes (22) simultaneously impinge against a substrate and thereafter displacing the array of tubes (22) from the operative position back to the inoperative position. The invention extends to a printing apparatus (10), a method of printing a layered array of spots of reagent compositions, a method of introducing reagent compositions into the tubes, a reagent introducing device for introducing reagent compositions into the tubes and a printing installation which includes the printing apparatus (10) and the reagent introducing device.
Abstract:
A pharmaceutical composition contains an extract obtainable from a plant of the genus Trichocaulon or Hoodia containing an appetite suppressant agent having the formula (1). A process for obtaining the extract and a process for synthesizing compound (1) and its analogues and derivatives is also provided. The invention also extends to the use of such extracts and compound (I) and its analogues for the manufacture of medicaments having appetite suppressant activity. The invention further provides novel intermediates for the synthesis of compound (1). 1
Abstract:
A method and installation for forming and maintaining a slurry are disclosed. The method withdraws a slurry from a reservoir and directs it at a heap of solid material from which the slurry is drained into the reservoir, the slurry containing additional solid material from the heap to increase its specific gravity. The volume of slurry in the reservoir and its specific gravity are controlled. The installation comprises a support having a support surface which slopes to permit slurry to drain therefrom A reservoir receives slurry draining from the support and has a liquid feed. A pump withdraws the slurry from the reservoir and pumps it to a spray nozzle for spraying slurry at a heap of material on the support.
Abstract:
This invention relates to a second generation, plant-produced synthetic Orbivirus candidate vaccine. The vaccine comprises a plant produced chimaeric Orbivirus virus like particle (VLP) comprising at least one structural protein from one Orbivirus serotype and at least one structural protein selected from another serotype of the Orbivirus, wherein both structural capsid proteins are from the same Orbivirus species. In particular the invention relates to a vaccine against an Orbivirus, a method of producing chimaeric Orbivirus virus-like particles (VLPs) for use in a method of prevention and/or treatment of an Orbivirus infection, the use of the chimaeric Orbivirus VLPs in the manufacture of a vaccine for an Orbivirus, and a method of preventing and/or treating an Orbivirus infection.
Abstract:
A method of re-stiffening an over-digested rubber modified bituminous binder includes admixing a reactive, stiffness inducing organic additive with the over-digested rubber modified bituminous binder to produce a re-stiffened rubber modified bituminous binder with an increased softening point. The admixing takes place at an elevated temperature of at least 185° C. A rubber modified bituminous binder suitable for both asphalt and seal surfacing applications that includes a digested rubber bituminous admixture with a softening point of at least 55° C. and a dynamic viscosity at 190° C. of less than 2000 mPa·s. A method of sealing or paving a surface includes applying a layer which includes a rubber modified bituminous binder to the surface, the rubber modified bituminous binder being in the form of a digested rubber bitumen admixture with a softening point of at least 55° C. and a dynamic viscosity at 190° C. of less than 2000 mPa·s.
