    摘要: A sample inspection apparatus includes a source of electromagnetic radiation, a beam former for producing a plurality of coaxial and substantially conical shells of radiation, a detection surface and a set of conical shell slot collimators. Each conical shell has a different opening angle. The detection surface is arranged to receive diffracted radiation after incidence of one or more of the conical shells upon the sample to be inspected. The set of conical shell slot collimators is provided at or close to the detection surface which each stare at different annular regions of different corresponding conical shells.

    摘要: A system for mitigating slugging in the conveyance of a subterranean resource can include at least one first pipe disposed proximate to a subterranean formation, where the at least one first pipe has a first cavity through which the subterranean resource traverses from the subterranean formation. The system can also include at least one second pipe disposed proximate to field equipment at an operating platform, where the at least one second pipe has a second cavity through which the subterranean resource traverses, where the field equipment is used to extract the subterranean resource. The system can also include a first slug mitigation assembly disposed between the at least one first pipe and the at least one second pipe, where the first slug mitigation assembly includes a first plurality of non-linear segments for reducing accumulation of gas or liquid pockets in the subterranean resource as the subterranean resource flows therethrough.

    摘要: A method of controlling the flow of a multiphase fluid through a pipeline that includes a riser pipe with a choke valve comprises receiving multiple signals dependent on fluid flow properties from a plurality of sensors in the topside area of the riser pipe, analysing the signals to establish a vector of measurement weights, the product of the vector of measurement weights and a corresponding vector of the signal values of a given time being dependent on the severity of a slug flow forming in the system. Further signals dependent on fluid flow properties are received from the plurality of sensors in the topside area of the riser pipe. A set position for the choke valve is then determined from the product of the vector of measurement weights and further values of signals to restrict characteristics of the flow in the topside from moving towards a severely slugging flow regime.

    摘要: The present invention describes a method for synthesis of relatively low molecular weight imprinted polymers using living polymerization, and their application in analytical chemistry, pharmacology, medicine and the food industry. Specifically the low-molecular weight polymers are synthesized by the polymerization of functional monomers in the presence of a template, such as a biological receptor, enzyme, nucleic acid, cell, virus, microorganism, tissue sample or drug using living initiator. The conditions of living polymerization ensure a relatively small size of synthesized molecules. Synthesized in this way molecules (dimers, oligomers, polymers, or their mixture) have a higher affinity to the template than the original monomers and can rebind it in vitro and/or in vivo. As a further aspect of the present invention, polymers synthesized as described above can be used as drugs in pharmacology and medicine, as receptor-specific ligands in analytical chemistry (sensors, assays), and for separations in the biotechnology, pharmaceutical and food industries.
