A method is presented for determining influent readily biodegradable substrate concentration (SS). The method is based on three different respiration rates, which can be measured with a continuous respiration meter which is operated in a cyclic way. Within the respiration meter nitrification is inhibited through the addition of ATU. Simulations were used to develop the respirometry set-up and decide upon the experimental design. The method was tested as part of a large measurement programme executed at a full-scale plant. The proposed respirometry set-up has been shown to be suitable for a semi-on-line determination of an influent SS which is fully based on the IAWQ #1 vision of the activated sludge process. The YH and the KS play a major role in the principle, and should be measured directly from the process.

Abstract Guidance for determining a S-N based fatigue capacity (safe life design) for preloaded connectors is included in Section 5.4 of the 2019 edition of DNVGL-RP-C203 (C203-2019). This section includes guidance on the finite element model representation, finite element based fatigue analysis and determination of the connector design fatigue capacity by use of one of the following methods: Method 1 by FEA based fatigue analysis, Method 2 by FEA based fatigue analysis and experimental testing and Method 3 by full-scale connector fatigue testing. The FEA based fatigue analysis makes use of Appendix D.2 in C203-2019 (“S-N curves for high strength steel applications for subsea”). Practical use of Section 5.4 is illustrated with a case study of a fatigue tested wellhead profile connector segment test. Further developments of Section 5.4 of C203-2019 are proposed. This included acceptance criteria for use of a segment test to validate the FEA based fatigue analysis of a full-scale preloaded connector.

Centrifugation is one of the key unit undertakings in the sugar business. Usually it is used ensuing to thickening of the stick juice, for instance at a high consistency region. The makers are of the view that a sedimentation hub will have the most sensible. The structure features of centrifugals from cluster to steady sorts have been thinks broadly, their operational limits have in like manner been discussed with helpful application by a couple of workers. Beside centrifugation, the mechanical separation in like manner expect an important activity for removing corruptions obtain a comparably sterilized thing, Screening is furthermore a technique used in various structures in the sugar business. The speed keeps up could be around 8000 rpm in the extent of 70-75% mud soddenness. The material vehicle in such a hub can catch suspension particles. The size extent of 1-2µm. It can have a wide extent of feed stream, which can be evaluated dependent on a full-scale. All of these concentrations as discussed for a significant determination of centrifugation of stick juice in the sugar business.

If, during full-scale trials, it is not possible to measure the state of the sea with a reliable wavemeter, then certain motion records may be combined to achieve the same end. The derivation of the wave spectrum from the time histories of pitch, heave (vertical acceleration), and bow immersion is presented. The problem of the conversion of acceleration to displacement is discussed. The method is applied to the particular case of the hydrofoil boat Sea Legs.
