A growing number of X-ray sources based on the free-electron laser (XFEL) principle are presently under construction or have recently started operation. The intense, ultrashort pulses of these sources will enable new insights in many different fields of science. A key problem is to provide x-ray optical elements capable of collecting the largest possible fraction of the radiation and to focus i...
The purpose of this research paper is to develop a framework to understand the consumer’s preference affecting variables and consumer’s perception choice in telecommunication service providers in India. The present study use a hybrid approach to access the relative efficiency based on fuzzy AHP and DEA model. The fuzzy AHP is used to determine weights of the consumer’s preference as criteria an...
Discusses the interaction between socio-economic systems and their natural environment, by examining the indicators of sustainable development. Areas covered by the operationalization of sustainable development indicators; Details on the global nature of environmental problems; Important strategy of the operationalization of sustainable development; Link between economic data and ecological ind...
Controlling spatiotemporal chaos in excitable media by applying low-amplitude perturbations locally is of immediate applicability, e.g., in treating ventricular fibrillation, a fatal disturbance in the normal rhythmic functioning of the heart. We look at a mechanism of control by the local application of a series of biphasic pulses, i.e., involving both positive and negative stimulation. This r...
The dual systems model posits that adolescent risk-taking results from an imbalance between a cognitive control system and an incentive processing system. Researchers interested in understanding the development of adolescent risk-taking use a diverse array of behavioral and self-report measures to index cognitive control and incentive processing. It is currently unclear whether different measur...
Spectral data during a chelatometric titration were utilized for determining an equivalence point of the titration. Three-dimensional titration data were analyzed by fitting to a theoretical equation that was derived from equilibrium equations among a metal ion, an indicator and EDTA. The equation with optimized parameters successfully explained the three-dimensional titration data. This method...
methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. the proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of biolog’s microplate system. as the microorganism are utilizing the carbon source (peptone), the reductio...
