Abstract Geological information on the Chotanagpur Granite Gneiss Complex (CGGC) has been reviewed with a view to: (a) identifying different metamorphic episodes; (b) developing an event stratigraphy in high-grade blocks; and (c) correlating episodes globally extensive orogenic processes. Integrating existing geological information, evolution of block CGGC divided into four stages associated distinct events ( M I − IV ). The earliest ) that is recorded granulite enclaves regionally felsic...

Abstract Miscible blends from plasticized poly(vinyl chloride), and epoxidized natural rubber having 50 mol% epoxidation level were prepared in a Brabender Plasticorder by the melt‐mixing technique. Changes torque temperature, density, dynamic mechanical properties, differential scanning calorimetry of samples examined as function blend composition. The chloride)/epoxidized behaved compatible system at all composition ranges evident their single glass‐rubber transition temperature ( T g )...

The micellization characteristics of N-cetyl-N-ethanolyl-N,N-dimethyl and N-cetyl-N,N-diethanolyl-N-methyl ammonium bromides have been investigated by microcalorimetric, conductometric, fluorimetric techniques. critical micellar concentration (cmc), counterion binding micelles, their aggregation number, thermodynamics evaluated at eight different temperatures in the range 288−323 K. Gibbs free energy, enthalpy, entropy, specific heat process direct calorimetric method as well indirect van't...

Abstract Polyesteramide polyols have been synthesized by melt condenstion using a mixture of alkanolamines, polyethylene glycols, and dicarboxylic acids/anhydrieds, the behavior or resin samples as interfacrial agents in unidirectional well random composites jute/epoxy jute/polyester has evaluated. Mechanical properties these composties with without interfacial determined along effect water uptake on such properties. The incorporation polyesteramide polyol (PEAP) resins interfacila found to...

This work presents a novel use of chaos-based non-linear techniques coupled with statistical methods for spoken language characterization in the speech signal domain. Our goal is to create framework that highlights linguistic commonalities. While Multifractal Detrended Cross-Correlation Analysis (MFDXA) assesses long-term cross-correlations between languages using cross-correlation coefficient as measure similarity, Fluctuation (MF-DFA) used examine correlations among languages. Bengali,...

The study reports the effect of two different types Hindustani music which are supposed to evoke contrasting emotions on brain activity using Electroencephalography (EEG) data. Two sets raga clips emotion (romantic/sorrow) were used in study. EEG was performed five male subjects while they listened clips. linear analysis their alpha and delta spectral power showed that most cases arousal based activities enhanced both Further, we a robust nonlinear method called Detrended Fluctuation...

ABSTRACT A suite of garnet‐wollastonite‐scapolite‐bearing calcsilicate granulites from the Eastern Ghats has been investigated to document controls mineral reactions during metamorphic evolution deep continental crust. The rocks studied show heterogeneity in modal mineralogy and phase compositions millimetre‐sized domains. Textural relations, compositional plots phases, established that clinopyroxene exerts a strong influence on formation composition garnet complex natural system. P‐T...

The most interesting feature of Indian Classical Music is the existence Raagas. Each Raaga has its own peculiar ascending and descending movement called Arohana Avarohana . Even if two (or more) Raagas are made up same notes, combinational varieties notes evoke different emotions. In this work, we envisage to study how emotion perception in listeners' changes when there an alteration merely a single note pentatonic also particular note(s) replaced by flat/sharp counterpart. Approximately 60...

The present study reports interesting findings in regard to emotional arousal based activities while listening two Hindustani classical ragas of contrast emotion. EEG data was taken on 5 naïve listeners they listened - Bahar and Mia ki Malhar which are conventionally known portray emotions. were analyzed with the help robust non-linear tools viz. Adaptive Fractal Analysis (AFA) Detrended Fluctuation (DFA). A comparative Hurst Exponents obtained from methods have been shown shows that DFA...

Music engages much of the brain, and coordinates a wide range processing mechanisms. This naturally invites consideration how music in brain might relate to other complex dynamical abilities. The tremendous ability that has affect manipulate emotions is undeniable, yet largely inexplicable. study cognition drawing an increasing amount research interest. Like language, human universal involving perceptual discrete elements organized into hierarchically structured sequences. can thus provide...

The concept of creativity and perception a raga is revisited in this work from the brain electrical response professional Hindustani musician. EEG was done to record when musician created imagery Jay Jayanti as well he listened same sung by him. We have quantified correlation values obtained different lobes during these two experimental conditions using robust non-linear technique called multifractal detrended cross-correlation analysis (MFDXA). With method, we seen that both imagination...

—Contact angle studies of miscible poly(vinyl chloride)/epoxidized natural rubber (PVC/ ENR) blends were carried out in air using water and methylene iodide. The solid surface free energy was calculated from harmonic mean equations. Blending PVC ENR decreased their contact or increased due to the improved chain mobility, accumulation excess polar sites at through conformational alterations resulting specific interaction ENR. work adhesion, interfacial energy, spreading coefficient,...
