Temperature coefficients of refractive indexes dn/dT determine the temperature characteristics of an optical fiber transmission system. These coefficients are analyzed critically for the first time to find refractive indexes at different temperatures for three optical fiber glasses fused silica (SiO/sub 2/), aluminosilicate and Vycor, and to predict(More)
Thermo-optic coefficients (dn/dT) determine the temperature characteristics of the nonlinear optical laser devices. These coefficients are analyzed critically by using a new model for the first time to formulate the temperature dispersion which can predict accurately the temperature bandwidths for various nonlinear interactions in a flux-grown KTP crystal.(More)
Eleven published and unpublished methods for extraction of chloride from plant tissue were compared, using a homogeneous sample of dried, ground maize leaves previously labelled with36Cl. The most effective method of extraction of Cl−, estimated by liquid scintillation counting of36Cl, was with hot water. However, six other methods, including either cold(More)
The tunable fiber lasers in the soliton regime are attractive ultrashort optical pulse sources. However, problems arise with fiber lasers due to their susceptibility to mechanical and temperature fluctuations affecting the optical path length of the cavities. The resulting instabilities are the major barriers for their applications in communications. The(More)
Purpose: To determine naproxen levels in human plasma using a new liquid chromatography-Mass spectroscopy/Mass spectroscopy (LC-MS/MS) method that involves a simple and single step extraction procedure using low-cost reagents. Method: A novel liquid chromatography–tandem mass spectrometry method for the quantitative determination of naproxen in human(More)
For the first time, an additive for conducting polymer membrane has been prepared from an Indian coal. Samla coal from Raniganj coalfield having 80% carbon on dmmf basis was first demineralised chemically and then degraded by oxidizing it with oxidizing agent followed by solubilization of oxy coal thus produced in polar organic solvent. The soluble part of(More)
