It is well known that modafinil is an effective wake-promoting agent, but there is growing evidence to suggest that modafinil may also enhance some aspects of cognition. In man, modafinil has been shown to enhance vigilance in sleep-deprived and/or narcoleptic subjects and also to improve executive-type functioning (predominantly inhibitory response control processes) across a variety of human ...

Usually, harmonics are the base point when engineers start to analyze waveform distortion. Frequencies of these voltage and current waveforms are integer multipliers of the base frequency of power system (50 Hz or 60 Hz). If it is not the case then these are named as intermediate harmonics. The sinusoidal waveforms of voltage characterize the ideal power system with the highest clarity of base ...

the objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. two wheat cultivars of grebe and houtman were reciprocally crossed with two synthetic genotypes of do1 and pol and then a complete set of the parents, f1, reciprocal f1 (rf1), f2 and back-cross generations (bc1 and bc2) of each cross were used for anthe...

Seismic events and aftershocks can cause devastating impacts on overground underground energy system infrastructure. This article designs a novel approach to restore functionality in response seismic stresses by using coordinated dynamic reconfiguration operation. First, the impact of infrastructure is evaluated, considering critical components, including electricity lines, substations, gas pip...
