TL;DR: In this paper, the scattering of light with altered frequency has been investigated in many crystals, and much valuable information has been accumulated, and their relation to theories of solid state are clearly matters of great interest.
Abstract: Since its discovery1, early in 1928, the scattering of light with altered frequency has been investigated in many crystals, and much valuable information has been accumulated. The significance of the results and their relation to theories of solid state are clearly matters of great interest.

TL;DR: Though ESPRIT is discussed in the context of direction-of-arrival estimation, it can be applied to a wide variety of problems including spectral estimation and has several advantages over earlier techniques such as MUSIC including improved performance, reduced computational load, freedom from array characterization/calibration, and reduced sensitivity to array perturbations.
Abstract: A new approach to the general problem of signal parameter estimation is described. Though the technique ESPRIT is discussed in the context of direction-of arrival estimation, it can be applied to a wide variety of problems including spectral estimation. ESPRIT exploits an underlying rotational invariance among signal subspaces induced by an array of sensors with a translational in variance structure (e.g., pairwise matched and co-directional antenna element doublets) and has several advantages over earlier techniques such as MUSIC including improved performance, reduced computational load, freedom from array characterization calibration, and reduced sensitivity to array perturbations. Results of computer simulations carried out to evaluate the new algorithm arc presented.

TL;DR: In this article, the authors present a review of fly ash characterization with reference to geotechnical applications and show that fly ash is a freely draining material with angle of internal friction of more than 30 degrees.
Abstract: Thermal power stations use pulverized coal as fuel. They produce enormous quantities of coal ash as a by-product of combustion. This calls for the development of strategies to encourage and establish technological concepts which will ensure consumption of fly ash in bulk. Among the various uses of fly ash, its bulk utilization is possible only in geotechnical engineering applications. This necessitates characterization of the fly ash with reference to geotechnical applications. This paper presents a review of such studies carried out. The results show that fly ash is a freely draining material with angle of internal friction of more than 30 degrees. The specific gravity is lower leading to lower unit weights resulting in lower earth pressures. It can be summarized that fly ash (with some modifications/additives, if required) can be effectively utilized in geotechnical applications.

TL;DR: In this paper, the authors describe most of the necessary building blocks for a scalable quantum computer with single-qubit and multiqubit gate operations, with particular emphasis on the implementation of single qubit and multiqubit operations.
Abstract: Quantum information encoded in single trapped ions provides a promising avenue towards a scalable quantum computer. This contribution describes most of the necessary building blocks for such a device. Particular emphasis is given to the implementation of single-qubit and multi-qubit gate operations.

TL;DR: In this article, the suitability of inexpensive leaf adsorbents to effectively remediate fluoride-contaminated water was evaluated using a series of aqueous solutions containing 2, 3, 5, 6, 8, 10, 12, and 15 mg F/l.
Abstract: The study assesses the suitability of inexpensive leaf adsorbents to effectively remediate fluoride-contaminated water. The efficiency of the sorption of fluoride ion is affected by pH, contact time, adsorbent dose, type and size of adsorbents and initial fluoride ion concentration. The adsorption equilibrium is well correlated by Freundlich and Langmuir models. Treated leaf powder was studied at various pHs (2, 4, 6 and 8) with a series of aqueous solutions containing 2, 3, 5, 6, 8, 10, 12, and 15 mg F/l. At the highest F-ion concentration (15 mg/l), the F-ion level in the effluent gradually decreased to 0 mg/l within 180 min at 29 +or-.5 degrees C when the dose of adsorbent is 10 g/l in a sample of 50 ml volume. With lower F- ion concentrations (2 mg/l) in the feed solutions the fluoride ion concentration steadily decreased reaching 0 mg/l after 150 min. Langmuir isotherm fits well for defluoridation of water using leaf powder.
