introduction the alborz structural zone in northern iran is the host of a number of important coal deposits. the gheshlagh coal mine is one of them, which is located 35 km southeast of azadshahr. coal bearing strata in the gheshlagh mining district occur in the middle part of the lower jurassic shemshak formation which consists mainly of shales, siltstones and sandstones. the geshlagh coals hav...

Numerical simulation of ultrasonic wave propagation provides an efficient tool for crack identification in structures, while it requires a high resolution and expensive time calculation cost in both time integration and spatial discretization. Wavelet finite element model provides a highorder finite element model and gives a higher accuracy on spatial discretization, B-Spline wavelet interval (...

We present the optical and mechanical design of a mechanically compliant quasitwo-dimensional photonic crystal cavity formed from thin-film silicon in which a pair of linear nanoscale slots are used to create two coupled high-Q optical resonances. The optical cavity supermodes, whose frequencies are designed to lie in the 1500 nm wavelength band, are shown to interact strongly with mechanical r...

Nanofiltration—a technology that selectively extracts critical materials from streams—can help secure resources while minimizing wasteful and unsustainable extraction practices. However, next-generation nanofiltration membranes must be designed with a fit-for-purpose framework in mind to fully harness its capabilities resource conservation minimize trade-offs. Rapid population economic growth r...
