    摘要： A method of pumping wellbore fluid, comprising the steps of: installing an electric submersible pump in a wellbore; and operating the pump at more than 4,500 rpm to pump the wellbore fluid. Pumping in this manner provides a number of advantages in use in that the required high-speed motor and pump is shorter for a given power than existing arrangements, and provides increased reliability due to reduced complexity. A much shorter motor/pump combination also allows such equipment to be used in deviated boreholes with a reduction in damage due to mishandling and bending, as well as facilitating assembly and testing in the manufacturer's plant.

    摘要翻译： 一种泵送井筒流体的方法，包括以下步骤：将电潜泵安装在井眼中; 并以超过4500转的速度操作泵以泵送井筒流体。 以这种方式泵送在使用中提供了许多优点，因为所需的高速电动机和泵对于给定功率比现有布置更短，并且由于降低的复杂性而提供增加的可靠性。 更短的电机/泵组合也允许这种设备在偏斜的钻孔中使用，由于误操作和弯曲而减少损坏，并且便于制造厂的组装和测试。

    摘要： An offshore riser system has riser joints, each having a pin and a box. The pin has an external grooved profile that is engaged by a locking element carried by the box of another riser joint. An actuating ring engages with the locking element to move it into the locked position. A retractable spider supports the string of riser while the new joint is being made up. A makeup tool on the riser deploying floor moves the ring relative to the locking element, causing the locking element to move to the locked position.

    摘要： A system for non-invasive measurement of parameters relating to a biological tissue comprising: a plurality of light sources, each operable to emit a light signal with one or more predetermined wavelengths; a light detector for detecting light from the tissue as a result of illumination by the sources, and means for applying modulation functions to the light emitted to implement code division multiplexing, each source being associated with a different function, wherein the functions are selected so that there is substantially no cross correlation between them, and wherein the sources have overlapping spectra.

    摘要： The present invention relates to a process for the production of long-chain polyunsaturated fatty acids in an organism by introducing, into the organism, nucleic acids which code for polypeptides with acyl transferase activity. These nucleic acid sequences, if appropriate together with further nucleic acid sequences which code for polypeptides of the fatty acid or lipid metabolism biosynthesis, can advantageously be expressed in the organism. Furthermore, the invention relates to a method for the production of oils and/or triacylglycerides with an elevated content of long-chain polyunsaturated fatty acids.The invention furthermore relates to the nucleic acid sequences, nucleic acid constructs, vectors and organisms comprising the nucleic acid sequences according to the invention, vectors comprising the nucleic acid sequences and/or the nucleic acid constructs and to transgenic organisms comprising the abovementioned nucleic acid sequences, nucleic acid constructs and/or vectors.A further part of the invention relates to oils, lipids and/or fatty acids produced by the process according to the invention and to their use.
