ABSTRACT River water cleaning from microorganisms using electrohydraulic discharges and ozonation was investigated. The processed water was highly polluted with the total number of microorganisms (70 400 cfu/mL) and total Escherichia coli bacteria (280 cfu/mL). The processing was conducted in a tube reactor with a hollow needle-rod electrode configuration. A 400-mL sample of river water was treated at different flow rates. Ozonation was performed in a washing bottle with an ozone concentration of 20 g/m3. The corona discharge treatment showed a steady decrease of bacteria and microorganisms but did not kill them completely. Spark discharge killed the bacteria and microorganisms completely; however, its energy efficiency was much lower than that of ozonation. The ozone treatment decreased the concentration of microorganisms and coli bacteria down to 785 and 10 cfu/mL, respectively, in 45 s which resulted in higher energy efficiency than processing using corona and spark discharges. The NPOC analysis of the treated samples showed its concentration of 5 ± 0, 4 ppm in all samples.

Distribution management system has been implemented and utilized by utilities around the world to support the system operators in their decision making process especially when emergencies occur in the distribution system. The system can vary from utility to utility due to the complexity of each system. This inevitably leads to the importance of the Distribution Management System design in order to get the system life cycle assessment. This paper presents an advantage of using a knowledge engineering technique along with knowledge management theory as an alternative approach in designing the Distribution Management System for Metropolitan Electricity Authority, Thailand. The results of this paper show that knowledge engineering technique is suitable to solve the designing problems of the Distribution Management System. Furthermore, this framework can also help utility capture, utilize and update their existing knowledge in designing their own system. Moreover, the comparison with consultant study is also introduced.

We all know that electricity is a part of our day today life and its demand has increased considerably due to the rise in the population. In order to supply power to the consumers, it has to be transmitted with minimum amount of losses such that the power system provides better efficiency. For this purpose, generation, transmission and distribution must be efficiently carried out considering all the factors in order to reduce losses and increase the power outcome. Transmission line (TL) plays an important role in transmitting electrical power. This paper deals with the maintenance of overhead (OH) TL by using a robot, which monitors the TL and detects any fault if present, so that electricity is transmitted with minimum amount of losses. Maintenance and detection of any kind of faults in the TL is a difficult task we face then and now because of risky factor while dealing with high voltages. Usually inspectors carry line inspection by aviation method which includes an observer who observes the TL by a helicopter driven by a pilot which is indeed a costly one and the video images provided from the helicopter is out of focus. Hence in order to achieve the same a robot is used which travels on the TL with the help of rollers on it. The robot inspects the TL and transfers the data regarding the line faults directly to the control room. In this method, the robot is equipped with a voltage and current sensor for the measurement of voltage and current, a RF module for communication purposes and a visual camera to capture images to be sent to the control room. This method is so advantageous in reducing cost, increasing efficiency and enhancing safety.

It is important to detect decomposition of insulating gas SF6 caused by partial discharges for gas-insulated switchgear (GIS). In the previous result, the author developed a novel partial discharges sensing using carbon nanotube (CNT) gas sensor. In recently, an application of high voltage DC for long distance electric power transmission has been often used in various countries as the interconnection system and overload demand. In this study we applied the CNT gas sensor to detect partial discharges generated by high voltage DC. There was polarity profile for DC compared AC discharges. It was found, response of the sensor in the case of negative discharges was much higher than positive discharges under the same experimental condition. And the decomposed gases for each case were identified by FT-IR spectroscopy. The result indicated absorption peaks correspond to SF4 and SOF2 of positive discharges was much higher than that of negative discharges.

In questo volume gli studiosi di editoria Gian Carlo Ferretti e Giulia Iannuzzi ricostruiscono attraverso 45 profili un esaustivo panorama delle collane che hanno espresso il meglio dell’offerta letteraria nel nostro paese, dal Novecento a oggi. Dalle collane più celebri e ormai storiche – come Lo specchio e i Gialli di Mondadori, I coralli e I gettoni di Einaudi, I Narratori di Feltrinelli, la Biblioteca Adelphi, la BUR di Rizzoli – fino alle tendenze più recenti e innovative dell’editoria, Storie di uomini e libri ci accompagna in un percorso affascinante e spesso sorprendente tra le politiche, le pratiche, gli orientamenti delle case editrici che maggiormente hanno contribuito a plasmare la nostra identità culturale e il nostro immaginario collettivo. Un prezioso strumento di lavoro per studenti e cultori della materia, ma anche una guida accessibilissima per chi desidera affacciarsi, da lettore curioso, nel «dietro le quinte» della letteratura, dove accanto a chi i libri li scrive c’è anche chi «li fa»: progettandoli e curandoli, con passione, coraggio, talvolta persino con un po’ di sana incoscienza.

Corona from high-voltage electrodes is employed in various electrostatic installations, such as ozonizers, air filters, powder sprayers and separators. Multiple-needle electrode designs are preferred whenever low corona onset voltage and good resistance to mechanical shocks are required. This paper aims at identifying a simple solution to overcome the main drawback of this type of electrode, the nonuniformity of the generated

Objectives Epidemics create extensive socio-behavioral changes in all areas, sport is no exception. The current study aimed at understanding the lived experience of athletic older adults from the Coronavirus Disease 2019 (COVID-19) pandemic. Methods & Materials The present qualitative research applied a phenomenological approach. The study participants were 16 athletic older adults in Tehran City, Iran who were selected by the purposive sampling method. Through in-depth and unstructured interviews, the required data were collected. The obtained data were analyzed using the seven-step Diekelman's (1993) approach. Results According to the obtained data, 4 categories of meanings were identified about the lived experiences of the explored elderly from the COVID-19 pandemic. These categories included the experiences of psychosocial isolation and thinking about death; the marginalization of older adult's sports; mood swings and lifestyle changes, and finding opportunities for sports activism. Conclusion These concepts of experiences in the life-world of athletic older adults in Tehran from the COVID-19 pandemic were the constitutions of their social action. In the case of proper analysis and application, they can be helpful in better managing professional sports in epidemics.

Corporate Social Responsibility (CSR), as a concept, has been the focus of deliberations and research over the past many years. India has a long history of individual and corporate philanthropy and the concept has been integral to Indian culture and value system since ancient times albeit informally. With the enactment of Companies Act in the year 2013 and subsequent amendments there to, the concept of Corporate Social Responsibility (CSR) has entered a new phase of evolution i.e. from being a voluntary activity to a statutory responsibility. Section 135 of the said Act mandates CSR contribution from every company that meets the prescribed threshold limits of net worth, turnover or profits. However, there are some grey areas in this provision and related rules which need further clarification for more efficient implementation of the Act. This paper discusses the concept of CSR and its evolution, pros and cons of mandated vis-à-vis voluntary CSR and issues and challenges involved in implementing the provisions of the Act and related rules. The paper also makes suggestions as to how these challenges and inadequacies can be resolved so that the objectives of the Act can be fully achieved
