Like all large cities around the world, Sydney's major underground sewers are deteriorating through age and reaching the end of their service life. To succeed in its vision to be the lifestream of Sydney for generations to come, Sydney Water's active sewer renewals program needs to renew underground sewers beneath heavily populated and environmentally sensitive areas. One of Sydney Water's pipeline rehabilitation contractors, Interflow, recently applied world class spiral wound lining technology to renew two of these sewers without excavation or interrupting services. This Australian made technology is pushing the boundaries in non-disruptive underground sewer renewal previously considered too difficult or impossible. The projects carried out for Sydney Water and discussed in this paper have twice received the International Society for Trenchless Technology's award for international project of the year.

Most of the large cities of the world are in trouble, and yet in the decades to come a vast additional number of people will live in cities. Enormous population increase produces the steep graphs we are familiar with, yet the graphs showing urbanization are even steeper, due to the migration from country to city.


In Hydropower generation company, the focus was on making use of the reliability-centred maintenance (RCM) principles in relation to expert systems in order to optimize maintenance of power generation assets at HPGC station. The researchers realised that in order for CBM to come out clearly, it is critical to do the RCM first. Naturally, the ageing equipment demands a paradigm shift in maintenance strategies in order to guarantee continuity of supply and meet the ever-growing stakeholder requirements. Increase in customer demand has worsened the situation. There is need to improve the overall equipment effectiveness (OEE) from the current 60% to the world class 85%, using the same old equipment in order to retain customer satisfaction.

AbstractBeyond knowledge, critical thinking, new ideas, rigorous science and scholarly development, this chapter argues for the university as a space of life. Through the complexities and incommensurabilities of academic life, and drawing on Julia Kristeva’s notion of revolt, Emmanuel Levinas’ notion of Otherness, and Novalis’ concept of Romantisierung, it makes a philosophical argument for recognizing what might appear as uncomfortable transgressions of the marketable, measurable characteristics of World Class Universities. In various ways, the chapter asks where there is space, in the World Class University, for elements which may not overtly align with the neoliberal clamour for international recognition and esteem. In elevating everyday life in the university, the chapter blurs boundaries of the celebrated, strived for rankings with the spaces of life that are dark and heterotopic, messily entangled with histories, polyphonic human and more than human voice, beings and energies, within the university. Revolt provokes a re-turn to re-question the ethics and boundaries of treatments of ‘world’ and ‘class’ in conceptions of the World Class University. Here, ‘World Class University’ is not necessarily a globally streamlined and internationally bench-marked institution, flexing its socio-economic muscles in the face of the world. Instead, it is an institution that speaks for others who have been made silent and deprived of their own critical voice. It speaks for the suppressed and marginalized, and it speaks for the ones who are no longer with us, or who have not yet arrived. It speaks for the people and the times yet to come.

AbstractThis paper identifies improvements which can be made to management plans for environmentally sensitive areas in Antarctica, drawing attention to (a) the characteristics of the antarctic environmental planning hierarchy which set it apart from planning and management systems applied to most other regions of the world, (b) the effectiveness of plans covering Sites of Special Scientific Interest (SSSI), (c) practical measures to improve site management (especially co-operatively), and (d) ways of integrating site management with broader conservation goals.

“The Book of Tribulations by Nu`aym b. Hammad al-Marwazi (d. 844) is the earliest Muslim apocalyptic work to come down to us. Its contents focus upon the cataclysmic events to happen before the end of the world, the wars against the Byzantines, and the Turks, and the Muslim civil wars. There is extensive material about the Mahdi (messianic figure), the Muslim Antichrist and the return of Jesus, as well as descriptions of Gog and Magog. Much of the material in Nu`aym today is utilized by Salafi-jihadi groups fighting in Syria and Iraq.

Analysis of linguocultural aspect of temporal nominations is impossible without involving the problems of hrononymic lexics. Chrononyms is an important information resource of a certain linguaculture, some distinctive peculiarities of conceptual picture of the world. The aim of the experimental analysis is a complex examination of the linguacultural aspect of temporal nominations that function in Chinese and Turkish languages reflecting the concepts of the world. The research was based on the material of the novels “Imperial woman” by Pearl Buck and “Roxolana” by Pavlo Zagrebelniy. The analysis of recent scientific publications allowed us to come to the conclusion that the investigation of hrononymic lexics can involve different theoretical and practical principles. Being guided by the existing classifications of chrononyms (N. Podolskaya, M. Torchinsky, S. Remmer) the linguocultural features of the following types of temporal chrononymic lexical units were identified and studied in the research: georthonyms, dynastic chrononyms, tumultonyms, parsonyms and mensonyms. The results of the research demonstrate that not all lexical units of temporal denotation chosen from the above mentioned novels refer to the class of chrononyms. The group under investigation includes the following lexemes: nominations of the lunar calendar, nominations of the solar calendar, nominations of mixed calendar and temporal slots denoting day and night. The basic system of chronology in the linguiacultures under analysis is the dominance of the lunar calendar nominations (Chinese picture of the world — 51,0 %, Turkish — 40,4 %). In the analyzed works the nominations of the solar calendar are used less often in the Chinese picture of the world; the usage of this unit reaches 20 %, and this phenomenon is historically conditioned. Mixed calendar nominations (21 % of temporal units) are rather common, solar calendar nominations are refined by the monthly calendar; it can be explained by the fact that the Chinese mind is conservative towards the new temporal system. In the Turkish picture of the world 45 % of temporal vocabulary belongs to the solar calendar since in the sixteenth century only a lunar calendar operated in the Ottoman Empire. It should be mentioned that significant place in the temporal vocabulary of “Roxolana” is conditioned by the influence of the linguistic personality of the author, who was a Ukrainian.

A new coronavirus pandemic is raging all over the world, especially in densely populated areas. Unlike most countries, more than half of the territory of Russia is not used by humans — which means that it is possible to settle large cities to avoid crowding people on a small area. The authors of the article consider wind power, namely vortex wind power plants, as a new source of energy that can be quickly and with less harm built in rural areas. The article also discusses the possibilities of an alternative Autonomous non-volatile installation "Air spring" for obtaining fresh water from atmospheric air.

This chapter examines evidence principally from the US that the Great Influenza provoked profiteering by landlords, undertakers, vendors of fruit, pharmacists, and doctors, but shows that such complaints were rare and confined mostly to large cities on the East Coast. It then investigates anti-social advice and repressive decrees on the part of municipalities, backed by advice from the US Surgeon General and prominent physicians attacking ‘spitters, coughers, and sneezers’, which included state and municipal ordinances against kissing and even ‘big talkers’. It then surveys legislation on compulsory and recommended mask wearing. Yet this chapter finds no protest or collective violence against the diseased victims or any other ‘others’ suspected of disseminating the virus. Despite physicians’ and lawmakers’ encouragement of anti-social behaviour, mass volunteerism and abnegation instead unfolded to an extent never before witnessed in the world history of disease.
