Use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. Nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. In this paper, the results of laboratory studi...
We revisit the classification of polarization observables of the cosmic microwave background. There exists a unified approach to the 3 × 3 density matrix by which intensity, linear and circular polarization are treated on an equal footing. The representations of the rotation group on the sphere contain certain right-left setup symmetries which have not been taken into account before. Left-right...
We have analyzed the interface structure and composition of La0.7Ca0.3MnO3/YBa2Cu3O7/La0.7Ca0.3MnO3 trilayers by combined polarized neutron reflectometry, aberration-corrected microscopy, and atomic column resolution electron-energy-loss spectroscopy and x-ray absorption with polarization analysis. We find the same stacking sequence at both top and bottom cuprate interfaces. X-ray magnetic circ...
Two groups have studied the loss of limbs in snake evolution by focusing on a long-distance cis-acting enhancer of Sonic Hedgehog. They find a progressive degeneration of binding sites for key transcription factors, mirroring the progressive limblessness occurring in these reptiles.
The study pertains to the investigation of the effect of embedment on the load carrying capacity and settlement of strip foundations on sand reinforced with geogrids. Geogrid being an inextensible reinforcing material is widely used all over the world mainly for retaining walls, abutments slope protection and below the foundation in poor soil. Some research works have been done the investigator...
In this paper, the effect of footing shape resting on dry sand when subjected to machine dynamic loading is experimentally investigated. A laboratory set-up was prepared simulate case at different operating frequencies. Nine models were tested examine effects combinations two parameters, including frequencies (0.5, 1, and 2 Hz) shapes (circular, square rectangular). The tests conducted under a ...
