through risk assessment process, it is necessary to identify, analyze, and prioritize systematically all environmental impacts of industries which have high destructive potentiality as well as representation of a mitigation plan. the current study aims at identification and prioritization of risks and impacts caused by abadan gas power plant. all kinds of the operational risks of the power plan...

During a conversation, it is common for a speaker to describe a third-party that the listener does not know. These professed impressions not only shape the listener’s view of the third-party but also affect judgments of the speaker herself. We propose a previously unstudied consequence of professed impressions: judgments of the speaker’s power. In two studies, we find that listeners ascribe mor...

conclusions accordingly, laser therapy in our protocol seemed to affect some of the nerve growth parameters, mostly on motor rather than sensory fibers. results in the two -point discrimination- test, there was no significant difference between the two groups in the thumbs but a significant improvement was observed in the index finger of the lt group. improvement of muscular examinations such a...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...

population growth, industrial pollution and high-energy consumption, cause the release of significant amounts of pollutants in the environment. power plants play an important role in the release of pollutants such as sulfur dioxide, nitrogen oxides, and carbon dioxide. if the necessary measures in the field of prevention and control do not be implemented, human health and other living creatures...

We present the first demonstration of frequency conversion by simultaneous second- and third-harmonic generation in a silicon photonic crystal nanocavity using continuous-wave optical excitation. We observe a bright dual wavelength emission in the blue/green (450-525 nm) and red (675-790 nm) visible windows with pump powers as low as few microwatts in the telecom bands, with conversion efficien...

Interaction of the third harmonic magnetic field with the third harmonic current in a five-phase synchronous reluctance motor (SynRM) can produce additional torque. However, it is still not clear about the SynRM power factor and its impact on the associated power converter because of the third harmonic components. Using time-stepping finite-element method, a mathematical model of the SynRM, whi...

Due to sensitive and important applications of free-electron laser in industry and medicine, improvement of the power and efficiency of laser has always been emphasized. Therefore, understanding the created field and examining the properties of the field in waveguides with different shapes and studying the sustainability of electrons movement are particularly important. In this study, the beh...

This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...
