Standard power plants

As plants have substances of medicinal values, they are used to treat number of diseases since long time. They had minimal or less side effect on human beings. In the present study, the antimicrobial and antioxidant properties of the flower extract of Nerium oleander was evaluated as a remedy for pathogenic diseases. The screening of various phytochemicals was conducted using a standard procedure using different solvents. Antimicrobial activity was evaluated by the disc diffusion method.

Objective of this study was to identify selected species of Cordyceps genus using DNA barcodes. Seven strains of Cordyceps were collected. Total DNA extraction and purification, PCR amplification and DNA sequencing were performed with standard chemicals and kits. The candidate ITS1-5.8S-ITS2 region was amplified and sequenced. Data were analyzed using Bioedit 7.2.6 and MEGA 7 softwares. Analysis of seven obtained DNA barcode sequences of collected samples revealed that the ITS1- 5.8S-ITS2 region provided high species discriminating power for Cordyceps genus.

In this paper, modelling and simulation of a control-oriented plant-dynamics tool for the molten salt fast reactor (MSFR) is presented. The objective was to develop a simulation tool aimed at investigating the plant response to standard control transients, in order to support the system design finalization and the definition of control strategies.

The calcium looping process, based on the reversible reaction between CaCO3 and CaO, is recently attracting a great deal of interest as a promising thermochemical energy storage system to be integrated in Concentrated Solar Power plants (CaL-CSP). The main drawbacks of the system are the incomplete conversion of CaO and its sintering-induced deactivation. In this work, the influence of particle size in these deactivation mechanisms has been assessed by performing experimental multicycle tests using standard limestone particles of well-defined and narrow particle size distributions.

The funding by the United States Nuclear Regulatory Commission of a research project to the Lawrence Berkeley National Laboratory and MCEER/University at Buffalo facilitated the writing of a soon-to-be-published NUREG on seismic isolation. Funding of MCEER by the National Science Foundation led to research products that provide the technical basis for a new section in ASCE Standard 4 on the seismic isolation of safety-related nuclear facilities.

This design change can improve the ability of the operators and personnel to respond to an emergency situation by using important equipment for a safe shutdown. IEEE 802.11 smartphones (Wi-Fi standard), Internet Protocol (IP) phones, personal digital assistant (PDA) for field work, notebooks used with web cameras, and remote site monitoring tablet PCs for on-site testing may be considered as wireless devices that can be used in domestic operating NPPs.

In the present study, a series of tungsten austenitic stainless steel alloys have been developed by interchanging the molybdenum in standard SS316 by tungsten. This was done to minimize the long-life residual activation occurred in molybdenum and nickel after decommissioning of the power plant. The microstructure and mechanical properties of the prepared alloys are determined.

An aircraft impact (AI) on a nuclear power plant (NPP) is considered to be a beyond-design-basis event that draws considerable attention in the nuclear field. As some NPPs have already adopted the seismic isolation technology, and there are relevant standards to guide the application of this technology in future NPPs, a new challenge is that nuclear power engineers have to determine a reasonable method for performing AI analysis of base-isolated NPPs.

In contrast to the consequences of change that are equally covering strategy, processes, leadership, company culture, and information systems (Kelly, 1998), most of the triggers and enablers of change can be located in IT (Evans, Wurster, 1999).

The whole world is in the grip of energy crisis and the pollution manifesting itself in the spiraling cost of energy and uncomforted due to increase in pollution as well as the depletion of conventional energy resources and increasing curve of pollution elements. To meet these challenges one way is to check growing energy demand but that would show down the economic growth as first step and to develop nonpolluting energy conversion system as second step. It is commonly accepted that the standard of living increases with increasing energy consumption per capita.

    This article contributes to the general debate on the link between population growth and the environment by analyzing the impact of demographic factors on two air pollutants. At the same time, it also con- tributes to a more focused debate on how population size and other demographic factors should be taken into account in future projections of air pollutant emissions.

In contrast, the smaller or so-called "fine" particles in the urban aerosol come from combustion sources, such as power plants, automobile, truck, bus and other vehicle exhaust or from the reactions that transform some of the pollutant gases into solid or liquid particles. These distinctions may be important because the current air pollution health effects literature suggests, although not with certainty, that for some key health effects the fine particles are more important than the coarse particles. These findings have led EPA to propose a new nationwide PM2.

This book is a companion volume to two published in 2011 by INTECH titled “Desalination, Trends and Technologies” and “Expanding Issues in Desalination”. The term “desalination” used in this series is in the broadest sense of the removal of dissolved, suspended, visible and invisible impurities in seawater, brackish water and wastewater.
