The Nam Ngiep 1 (NNP1) Hydropower Project in Lao PDR has constructed a 167 m-high roller compacted concrete (RCC) dam. Class C fly ash (FA) procured from the Mae Moh coal-fired power plant Thailand been selected as supplemental cementitious material for NNP1 RCC dam, to control hydration heat generation and improve workability. Though rarely used globally RCC, it was found that FA acceptable be...
Hydropower accounts for about 16 % of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity – t...
Regulated rivers in the United States are required to support human water uses while preserving aquatic ecosystems. However, the effectiveness of hydropower license requirements nationwide has not been demonstrated. One requirement that has become more common is "run-of-river" (ROR) operation, which restores a natural flow regime. It is widely believed that ROR requirements (1) are mandated to ...
This paper contributes towards exploring the technical and institutional feasibility of small hydropower storage and pumped-storage schemes in Switzerland. Within the European and Swiss context of the facilitation of renewable energy technologies, which includes small hydropower (SHP), intermittent sources such as solar and wind increase the need for additional energy storage capacities. Hydrop...
Today, technological innovation is often called upon to deliver solutions to the sustainable development challenges that the world faces. The integration of different technological systems is promoted as a main option for that goal. By integrating systems, waste from one system can be used as feedstock for another system, equipment can be usedmore efficiently by economies of scale, and/or the s...
Turbine is the most critical component in hydropower plants because it affects the cost as well as overall performance of the plant. Hence, for the cost effective design of any hydropower project, it is very important to predict the hydraulic behavior and efficiency of hydro turbines before they are put in actual use. Experimental approach of predicting the performance of hydro turbine is costl...
Based on the principles of system thought and related enterprise integration methodologies, a process oriented methodology and ICMMS (Intelligent Control-Maintenance-technical Management Systems) reference model for hydropower plants are proposed. Because the structures of the hydropower generating process are unchanging from the point of view of energy conversion, the methodology employs the p...
The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...
