Abstract

Interpretation of gravity and magnetic data in a strip of 250 sq.km. over Lanji-Darekasa tract of Khairagarh basin has been attempted in order to delineate regional structures and controls of uranium mineralisation in the province. Magnetic map indicates three parallel east-west trending lineaments representing basic dykes cutting across the geologic fonnations. The orthogonally intersecting gravity and magnetic trends around Saheki (80° 31' : 21° 27' 30") reveal a tectonised zone favourable for uranium minelisation. Gravity low of the order of five milligals near Nimbanaka (21° 19' : 80° 31' ) suggests a sharp increase in the thickness of Bijli rhyolites.

Based on observed gravity, magnetic data and the available surface geological information, the paper proposes a model for configuration of Khairagarh basin along Lat. 21° 25' between Parsori and Khairagarh. Maximum thickness for volcano-sedimentary pile filling the basin along this section is estimated to be around 2300m. The model also indicates possibility for the presence of a concealed high density formation (Pitepani Volcanics?) below Bortalao sandstones.

Abstract

Currently many websites in the internet are built with the help of XML technology. XML is used to process semi-structured as well as structured data. Also XML was designed to transport and store huge volumes of data. Compatibility between different platforms can be easily achieved with the help of XML. To manage information stored in XML and to extract information in efficient way. Many techniques have been proposed to speed up the performance of XML data. The processing is known as “XML mining”.
In this paper, based on the XML data structure, we are going to analyze the similar kind of patterns and propose the data mining technique about extracting the similar patterns from XML data. In this paper to speed up the performance we are going use FP-growth algorithm for mining similar patterns about the XML data structure. The proposed method using FP-growth algorithm applied to XML query subtrees surpass Apriori algorithm.

Keywords

Abstract

Owing to the continuous development towards the miniaturization of electronics, newer dielectric materials were sought which would enable to achieve high energy density for many applications. To achieve a compact and reliable design of electrical equipment for the present day requirements, there is an urgent need for better and smart insulating materials and in this respect, the reported enhancements in dielectric properties obtained for polymer nanocomposites seems to be very encouraging. Such change was often favourable for engineering purpose. In this case, we obtain a high dielectric permittivity and low dielectric loss. So, it can be used in many applications like electrical insulation for power apparatus, power cables, insulated wires and outdoor insulators too.

Keywords

High Voltage Insulation Nanocomposites, FTIR, Relative Permitivity and Tan Delta.

Abstract

A simple, accurate and precise spectroscopic method was developed for simultaneous determination of Amlodipine besylate and Olmesartan medoximil in tablets using first derivative zero crossing method. Amlodipine showed zero crossing point at 237 nm while olmesartan showed zero crossing at 259 nm. The dA/dλ was measured at 259 nm for amlodipine and 237 nm for olmesartan and calibration curves were plotted as dA/dλ versus concentration, respectively. The method was found to be linear from 5 - 30 μg/mL for amlodipine (r² ≥ 0.9999) at 259 nm and 5 - 30 μg mL-1 for olmesartan (r² ≥0.9998) at 237 nm. The within day and between day variations showed coefficient of variation (CV%) values less than 1.5% for both drugs. The limit of detection was 0.06 and 0.14 μg/mL for amlodipine and olmesartan, respectively. The limit of quantification was 0.18 and 0.43 μg/mL for amlodipine and olmesartan, respectively. The method was successfully applied for simultaneous determination both drug in tablet dosage form.
