Major sewerage work in Littleborough near Rochdale in North West England resulted in the closure of eight Combined Sewer Overflows and the construction of a new overflow incorporating downstream storage. The paper describes the method, named the CARP procedure, used in setting the frequency and volume of discharge from the new overflow and, therefore, the size of the tank. The effect of the resewerage work on the River Roch is being studied as a collaborative exercise involving the University of Manchester, Water Research Centre and North West Water. This is part of the River Basin Management Programme of the Water Industry of England and Wales (Clifforde et al, 1986). First results indicate that the tank will not operate as frequently as predicted by computer modelling. The discharge from the new Combined Sewer Overflow would not appear to significantly effect the river. This is to be confirmed by further fieldwork.

The development of the Wallingford Procedure WASSP (1981) and the MOSQITO (Moys 1987) models will provide the sewerage engineer with design tools to assess the quantitative and qualitative performance of sewer systems. As part of the development of such a quality model, the University of Manchester, financed by the Water Research centre and North West Water, have undertaken a fieldwork program of research to monitor the hydraulic performance and the temporal variation of pollutants in the inflow and the overflow at five combined sewage overflows in the North West of England. These projects are integrated into the program of research co-ordinated by the River Basin Management group at WRc Engineering. This paper describes the instrumentation used at a typical field site and illustrates the monitored temporal variation of pollutants for a number of storm events. These results show the complexity of the monitored pollutographs and highlight the large number of variables which influence combined sewer quality. Using data monitored in 1986, it is hypothesised that the long term impact of combined sewer discharges on receiving waters may be estimated from the flow retention performance and some estimate of annual average pollutant concentration. To predict the short term impact on river quality it is necessary to consider the complex processes associated with combined sewer flow and to include the separation performance of the overflow structure.

The detrimental influence of storm sewer overflows on urban river quality has been widely recognised for many years. One objective of the WRc River Basin Management programme is the development of a river impact model capable of predicting the transient quality changes in receiving waters due to intermittent storm sewage discharges. The production of SPRAT (Spill Pollution Response Assessment Technique) is the first step in the development of such a model. SPRAT incorporates a number of significant simplifications, most notably plug flow and instantaneous mixing, and does not implicitly take into account the effects of dispersion. These simplifications reflect the large errors associated with the model inputs. These errors severely limit the potential accuracy of any river impact model. The model has been applied to the Bolton river system in North West England. The development and application of SPRAT has enabled the requirements for a more sophisticated river quality impact model to be clearly defined, in addition to highlighting the problems associated with gathering suitable data with which to build and calibrate such a model.

Visible pollution discharged from two combined sewer overflows were studied using passive Trash Trap devices and the UK Water Research Centre Gross Solids Sampler. Relationships are presented for the number of visible solids and the mass of gross solids discharged during an event. The differences in the behaviour of the overflow types are reported on and they are categorised using the Trash Traps.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Modeling rainfall runoff can help to understand what is happening throughout the system, how can control of water to prevent flood, and how much the quality of runoff can change in urban area. Modeling sewer system help decision maker to indicate best strategy to prevent flooding, reduce runoff pollution, reduce cost of wastewater treatment and determine best suitable LID to an urban area. This dissertation first starting with analysis the complexity of model necessary to get accepted result in term peak flow, runoff volume, numbers of flooding nodes and time to peak. Modeling requirements may lead to system simplification, as in limiting the size of the pipes included in the analyses. Researchers analyzed the combined sewer system of the urbanized Town Fork Creek catchment in Kansas City, Missouri using PCSWMM to assess the potential impact of the simplifications on hydraulic results.

Collaboration in decommissioning offshore infrastructure could save both industry and taxpayers billions of dollars and facilitate new industries and exports for Australia, especially in the Asia-Pacific region. At the end of the liquefied natural gas (LNG) plant construction boom, Australia must not miss out on this major new opportunity. The 2017 bid for Commonwealth funding to establish a Decommissioning Offshore Infrastructure Cooperative Research Centre (DOI-CRC) involved more than 30 participants and many other collaborators. High-level commitments were made by Chevron, Woodside, Shell, BHP, ExxonMobil, Quadrant, The University of Western Australia, Curtin University, the University of New South Wales, Deakin University, Australian Maritime College, CSIRO and Australian Institute of Marine Science. A Perth-based DOI-CRC was supported by National Energy Resources Australia, National Offshore Petroleum Safety and Environmental Management Authority and other Australian Government bodies and by the Western Australian Government and its Chief Scientist and agencies but did not receive sufficient support from the CRC Advisory Committee. Meeting decommissioning challenges in the North West Shelf, Bass Strait and the Northern Territory in a timely, robust, scientific, efficient and cost-effective manner that contributes to a sustainable marine environment should draw upon and augment international best practice with local capability and expertise. Good science and innovative engineering are needed to support regulatory approval of options such as ‘rigs to reefs’ and commercial opportunities such as in waste management and expanded fishing and tourism. APPEA and operators wish to maintain DOI-CRC’s momentum and learn from UK research arrangements through funding marine science projects. But we must be much broader if we are to build a sustainable world-class Australian decommissioning industry. In particular, we need to work more closely with state and federal regulators and policymakers and undertake more engineering science research and innovation.

Artistic Talent

On 17 April 1899, in Kirkham, Lancashire, Vincent Brian Wigglesworth was born into a talented and idiosyncratic Victorian family with roots going back to the hamlet of Wigglesworth in the south-west comer of Yorkshire. He was the son of Sydney Wigglesworth, M.R.C.S., L.R.C.P., Captain R.A.M.C., and Margaret Emmeline (née Pierce). Sydney Wigglesworth was a general practitioner but also an amateur mechanic and inventor who had studied engineering at Owens College (later the University of Manchester) before changing to medicine. He made scale models of locomotives and was a passionate pioneer motorist. Margaret Pierce came from a well-to-do family of London solicitors originating from Devon yeoman stock with business and nautical interests (Pierce Sound in North West Canada is named after an eighteenth-century ancestor). As an amateur painter trained at South Kensington she developed a great eye for colour. It was the kind of family that produced many famous Englishmen, artists as well as scientists. V.B.W.’s scientific illustrations show that he inherited his mothers artistic talent. His elder brother’s career as a landscape painter was cut short by his early death in 1936.

April 1, 2001 marked the fourth anniversary of the Stockholm Agreement (SA), a period during which almost 80% of the roll-on/roll-off (Ro-Ro) fleet in North West Europe have been subjected to calculations, model testing and numerical simulations in the struggle to meet these demanding new requirements. The experience gained has been invaluable in understanding better the problem at hand and is being utilized to shape new developments likely to lead to more meaningful requirements. The North-South divide, however, continues to cause unrest, particularly at the European level. Efforts to assess the status quo in North West Europe, and to use the information amassed so far as a means to predict the potential impact of introducing the SA in the South, led to a dedicated call by the Commission and to a contract being awarded to two closely collaborating teams, one at the Ship Stability Research Centre of the University of Strathclyde under the leadership of Professor Vassalos and one at the Ship Design Laboratory of the National Technical University of Athens, under the leadership of Professor Papanikolaou, representing the North and South of Europe, respectively. This background provided the incentive for an introspective look at the SA, with a view to ascertaining its status before embarking into future projections. This forms Part 1 of the SA related research with Part 2 aiming to cover the results of the Commission study itself.

The International Nuclear Management Academy (INMA) is an International Atomic Energy Agency (IAEA) framework to support the establishment and sustainability of Master’s level Nuclear Technology Management educational programmes and the development of nuclear technology management professionals. The INMA framework describes a broad range of competencies across four Aspect Groups of External Environment, Technology, Management and Leadership, that have been identified as the basis for the successful management of nuclear projects. By following the INMA framework these competencies can be achieved by nuclear technology subject matter experts to support their career path into managerial roles or by experienced managers moving into the nuclear sector. The IAEA in conjunction with worldwide universities with nuclear education programmes have developed an endorsement process to recognise which university Master’s programmes adhere to the INMA framework and can therefore produce graduates with the required competencies. It is also recognised though that the implementation of these competencies can only be fully achieved through on-the-job training or experiential learning. A combination of education and experience is therefore required to be recognised as a nuclear technology management professional. To date two universities, The University of Manchester and the Moscow Engineering Physics Institute, have received INMA endorsement for their Master’s programmes in Nuclear Technology Management. The University of Manchester programme is part-time while the MEPhI programme is a two-year full-time programme. Several other universities — North West University and University of the Witwatersrand (both South Africa), Texas A&M University and the University of Tokyo having been assessed for endorsement, and many others developing nuclear technology management programmes are entering the process. The IAEA organise an INMA Annual Meeting where universities can meet to express interest in the programme, learn more about what is required for the programme and endorsement, and exchange best practices. The International Nuclear Management Academy is therefore making significant contributions to improving nuclear technology management competencies leading to improved managerial decision making with the associated benefits to the global nuclear industry.

A hybrid propulsion system for a passenger car is described and its preliminary design and performance discussed. A gas turbine operating in a controlled on-off mode, a generator, a battery pack, an inverter, and an electric motor constitute the power system, with an electronic vehicle management unit supervising the system for control and regulation. Road simulation tests are presented, based on standard ECC driving mission cycles. The turbogas performance might be improved adopting ceramic blades, with a possible increase of the TIT (turbine inlet temperature), and a consequent increase of its efficiency. The paper reports on the first results of a study in progress, within a joint research program between the University of Roma 1 “La Sapienza” and the Italian Research Centre of ENEA-Casaccia.

Preface to Review of Greenland activities, 1996. Geology of Greenland Survey Bulletin, 176, 6-8. https://doi.org/10.34194/ggub.v176.5027 _______________ Activities concerning Greenland that are undertaken by the Geological Survey of Denmark and Greenland (Danmarks og Grønlands Geologiske Undersøgelse: GEUS) were maintained at an unreduced level in 1996. Following the merger in 1995 of the former Geological Survey of Greenland (Grønlands Geologiske Undersøgelse: GGU) with the Geological Survey of Denmark (Danmarks Geologiske Undersøgelse: DGU) to form the present institute, 1996 saw the move of the great majority of former GGU staff from the University complex at Øster Volgade to the former DGU office complex at Thoravej, in north-west Copenhagen. The former GGU geochemistry laboratories and some other facilities will remain at Øster Voldgade, together with the Danish Lithosphere Centre (DLC); the latter is a research centre funded by the Danish National Research Foundation and administratively linked to GEUS, and hosted jointly by GEUS and the Geological Institute of the University of Copenhagen. It is planned that GEUS will move to the renovated Øster Voldgade complex, which will house the new GEOCENTER, in the year 2001. This major new geological research centre will comprise GEUS, hopefully including the Danish Lithosphere Centre, together with the Geological Institute, Geological Museum and Geographical Institute of the University of Copenhagen. The final decision to establish the GEOCENTER at Øster Voldgade was made by the Danish Parliament in December 1996, with the passing of the 1997 Finance Law, as an element in Denmark’s National Research Strategy. A grant of 190 million kroner has been allocated for renovation, rebuilding and relocation expenses. As part of an agreement between the Prime Minister of Denmark and the Premier of the Greenland Home Rule Government concerning strengthening of the mineral resources sector in Greenland, two GEUS geologists were seconded to the Home Rule Minerals Office in Nuuk throughout 1996. This arrangement forms part of the strengthening of competence in Greenland in relation to both mineral and oil resources, together with improvements in two-way communication of geological information of special relevance to the non-living resource sector.
