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.

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.

In Bali, especially at Tiga Nusa, the need for electricity is increasing along with the development of the construction of resorts and hotels. In this study, a sample of cases was taken in 2014 regarding the Lembongan feeder network system which was still installed with several LBS (Load Break Switch) which used to localize interference. Therefore, to anticipate interference and improve the reliability of feeders, one of many ways is to add an automatic back cover (recloser). This study aims to determine the optimal recloser location in the Lembongan feeder by using a combined method of fuzzy logic and particle swarm optimization with the help of MATLAB software. The results of this study obtained the best location of the recloser in group 5, namely the area between LBS SD 3, LBS Celagi Empak, and LBS Lembongan by adding one recloser. The SAIFI value is 1,9471 times / customer / year and the SAIDI value is 1,4596 hours / customer / year where the world class service parameter standard for the SAIFI reliability index is 3 times / customer / year and the SAIDI reliability index is 2,5 hours / customer / year.

The University

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.

Hydro power is a renewable source of energy used in most parts of the world. India is very rich in hydropower potential. It is the only clean and renewable source today making significance in the world of power production. With the rising economic growth and income level India is bound to have higher demand for electricity supply. India presently has an installed power generation capacity of 284,303MW (2015) inclusive of Hydropower which is 42,623MW(2015) .The situation is highlighted by the peak power deficit—shortfall in supply of power when the demand is maximum—was 5.2% in year 2013-14.With the fast depleting natural resources, it becomes mandatory that we increase the use of Renewable Resources for Power generation .When Thermal power in 2007 was 64% of the total generation and Hydro power was 26% and in 2015 instead of the thermal graph falling and Hydro power rising we see a different picture . In 2015 thermal has grown to 70% and hydro has fallen to 15%.Hydropower is such a good source for power why do we see the graph falling every year?? The amount of land submergence required for large Dams is the biggest concern where the Forest Act and the Environment Act also offer rigidity towards the same. Relative to so much submergence arises another major problem of Rehabilitation and Resettlement .Climatic changes and other negative effects of fossil fuel for power generation are growing concerns and therefore driving the expansion of hydropower around the world. The Reservoir based hydropower projects have also come under criticism due to carbon dioxide and methane emissions beyond acceptable limits. Ecological and many more issues that are preventing Hydro power as becoming the major source of electricity generation. In this paper we will review the major issues faced due to large hydropower plants and why they are not termed as Renewable sources.

Study Application

The final case study application was at a thermal power generation company. In large-scale industrial applications, the controlling and optimization of the parameters must be done efficiently and effectively so as to attain smooth operation of the plant. In this research, the main control parameters in the boiler were identified as coal flows, temperatures in the combustion zone, air-to-fuel ratio and ash content, that is, the percentage of ash in raw coal, and mineral content. These parameters are monitored to avoid clinker formation in the super heater tubes of the boiler. Condition-based maintenance (CBM) approaches were used to monitor the boiler parameters. Fuzzy logic was applied in the monitoring of these parameters.

“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.

Tarbela Dam

The World Bank Study," Water and Power Resources of West Pakistan" [1], is one of the most thorough-going and sophisticated of its type. In re¬reading it we have been struck by a curious argument related to the real benefits to be expected from the construction of the Tarbela dam. It was designed to produce electricity as well as to irrigate land and it was necessary to estimate the benefits that the electricity would confer. One way of doing this was to estimate the saving that would be made by using hydro-power instead of natural gas or imported fuel, for electricity generation. This meant that an appropriate set of prices had to be estimated for Pakistan's supply of natural gas. The way in which this was done was, to say the least, unusual. The relevant passage justi¬fying the approach adopted is as follows:

An outbreak of “Pneumonia of Unknown Etiology” occurred in Wuhan, China, in late December 2019. Later, the agent factor was identified and coined as SARS-CoV-2, and the disease was named coronavirus disease 2019 (COVID-19). In a shorter period, this newly emergent infection brought the world to a standstill. On 11 March 2020, the WHO declared COVID-19 as a pandemic. Researchers across the globe have joined their hands to investigate SARS-CoV-2 in terms of pathogenicity, transmissibility, and deduce therapeutics to subjugate this infection. The researchers and scholars practicing different arts of medicine are on an extensive quest to come up with safer ways to curb the pathological implications of this viral infection. A huge number of clinical trials are underway from the branch of allopathy and naturopathy. Besides, a paradigm shift on cellular therapy and nano-medicine protocols has to be optimized for better clinical and functional outcomes of COVID-19-affected individuals. This article unveils a comprehensive review of the pathogenesis mode of spread, and various treatment modalities to combat COVID-19 disease.
