摘要:
The invention relates to a method for producing an antimicrobial fabric or yarn, said method comprising the steps of immersing a fabric or yarn in an aqueous solution of a metal salt whilst simultaneously subjecting said solution to ultrasonic radiation; and removing the fabric or yarn from said solution and subsequently converting the metal salt in situ in the fabric or yarn into metal oxide nanoparticles, preferably via chemical and heat treatment. Fabrics and yarns obtained or obtainable by such method are also provided. In a further aspect the invention provides an apparatus for performing such method.
摘要:
The present invention provides the use of a particulate polymer material as a support for an active agent, characterised in that said polymer material is a polymer produced by copolymerising an unsaturated heterocyclic monomer and squaric or croconic acid or a derivative thereof.
摘要:
A water-soluble photoluminescent compound including a symmetrical skeletal structure of the formula (A) in which x may represent any integer, and in which the phenyl rings may be substituted, is disclosed. A protein detector comprising such a compound and a method of measuring the total dissolved protein content of a fluid sample are also disclosed.
摘要:
The present invention covers a current-driven molten metal/molten electrolyte system whereby on the system an additional, external, timevarying and/or alternating magnetic field is imposed. Advantageously, the magnetic field applied may essentially be a vertical magnetic field.
摘要:
In a method of segmenting an image a first, seed pixel unit is selected from a first group of pixel units in which the pixel units all have substantially the same grey-level intensity. The grey-level intensity of said first pixel unit is compared with the grey-level intensity of each of selected adjacent pixel units of said image and those pixel units with grey levels within a selected range are assigned as a pixel unit of the same region as said first pixel unit. This comparison process is repeated for each of the pixel units in the image, those already having been assigned being ignored. A further seed pixel unit is selected from a further group of pixel units in which the pixel units all have substantially the same grey-level intensity and the comparison process repeated for all of the unassigned pixel units. Further seed pixel units are selected and the comparison process repeated until all the pixel units of the image have been assigned. A watershed transform is then applied to provide the segmented image.
摘要:
A supporting system supports a rail of a rail track above a substrate. The system includes a support having an upper surface for supporting the rail and a lower surface facing the substrate. The system also includes means for maintaining support between the lower surface and the substrate in response to separation of the rail and the substrate and inhibiting movement of the rail towards the substrate.
摘要:
A solar energy collector (10) has a generally planar panel (12). The generally planar panel has upper (16) and lower (20) generally planar surfaces, first and second end regions, and a planar portion (20) formed with a plurality of passages (22) extending up from one of the end regions of the other for receiving a solar energy-absorbing liquid. A respective end closure (14) is coupled to each or the end regions for conducting the solar energy-absorbing liquid to and from the passages. At least one of the end closures has means (42) enabling communication of at least one cavity with atmosphere. Each end closure has upper (26) and lower (28) limbs for sealingly gripping upper and lower surfaces of the panel (34). A kit of parts for a solar energy collector is also provided.
