The total substitution of traditional reinforcement in the form steel bars by fibres can be mainly found elements with favourable boundary conditions and subjected to low-moderate load levels. However, rigorous study fibre reinforced concrete (FRC) its potential fields application over last decades permitted this material face structural greater responsibility terms integrity mechanical capacit...

Two large-scale north-dipping, low-angle normal faults cut the Everest massif at the top of the High Himalayan slab in Nepal. The upper fault the Qomolangma Detachment, follows the north slope of Everest from above the ‘Yellow Band’ at c. 8500 m on the Southwest Face down to the Rongbuk glacier. On the south side of Everest this fault places unmetamorphosed Ordovician mudstones and limestones a...

A simple model is developed to characterize the behavior of radio-frequency absorbers at low frequency. The absorber is represented by a flat, homogeneous, isotropic slab of lossy material, with effective constitutive parameters. These parameters are determined by a fit to measured data. Excellent fits are obtained in the two applications considered. The model is intended for use in the charact...

We studied enhancement and suppression of spontaneous emission in thin-film InGaAs/InP photonic crystal at room temperature. Angular resolved photoluminescence measurements were used to determine experimentally the band structure of conduction band of such a photonic crystal and overall enhancement of spontaneous emission. We demonstrated spontaneous emission enhancement in thin slab photonic c...
