A check list of marine fungi recorded from India is compiled on the basis of the present studies along the coast of Daman, Diu Island, Gujarat, Goa and Maharashtra and published literature. Distribution of 207 species of marine fungi (14 Labyrinthulomycota, 4 Chytridiomycota, 4 Oomycota, 139 Ascomycota, 3 Basidiomycota and 43 Mitosporic fungi) reported so far from marine habitats along various coastal states, Islands and Union territories of India. The 28 species of marine fungi are considered as doubtful records (26 Ascomycota and 2 Mitosporic fungus) are also listed. The record from West coast accounts for 167 sp. and there from East coast 152 sp., Andaman-Nicobar Islands 64 sp., and Lakshadweep Islands 57 sp. Four fungal species were isolated from deep sea sediments in the central Arabian Sea. This data will be useful in the compilation of marine biodiversity of India.

Emotion and stress plays a significant role in day to day life. Stress arise many complicated medical situation. The aim of this study is to create a new fusion of EEG signals for emotional stress recognition and North Indian Classical Music. In this paper, proposed a method which extracts the EEG signals with the help of scalp of the brain in responding to various stimuli, and recognize the basic emotion like Happy, anger, sad and fear. The EEG signal feature is extracted by using the method of Kernel Density Estimation and emotions can be recognized by using the Multilayer Perceptron. This method visualizes the stress perception during the listening of Raga and neural network classifiers obtained an accuracy of emotion on the flow of valence of arousal model. © 2015 IEEE.

We attempt to demonstrate comprehensive analysis of experimentally obtained adverse supercapacitive performance of cobalt hydroxide (Co(OH)2)-polyaniline (PANI) hybrid nanocomposites (HNs), prepared potentiostatically via electrochemical deposition method, compared to phase pure individual nanostructures. Morphologically amorphous Co(OH)2, PANI and HNs are entirely different from one another. The electrochemical properties of the Co(OH)2, PANI and HNs electrodes have been investigated by cyclic voltammograms, galvanostatic charge-discharge and electrochemical impedance spectroscopy measurements. The specific capacitances of PANI, HNs and Co(OH)2 are found to be 3.06F/g, 215F/g and 868F/g, respectively, at a sweep rate of 10 mV/s in 1.0 M NaOH electrolyte, whereas the stabilities and voltammetric charges, assigned to these electrodes, are 47%, 60% & 55% (after 1000 cycles) and 17.22 mC/cm2, 836.39 mC/cm2 and 1128.73 mC/cm2, respectively. Obtained adverse (inferior) supercapacitive performance values of HNs electrodes have been demonstrated on occurrence of inner and outer charges concept. Our work demonstrates plausible causes for observed smaller supercapacitor performance in hybrid/composite nanostructured electrodes (not a common practice) and useful to researchers working in composite/hybrid symmetric and asymmetric supercapacitor fields. © 2016 Elsevier B.V.

A precise and selective method has been developed for extraction spectrophotometric determination of osmium(IV) and ruthenium(III) using o-methoxyphenyl thiourea (OMePT) as a chromogenic ligand. The basis of the proposed methods are osmium(IV)-OMePT complex was formed in 0.8 mol L−1 at room temperature while ruthenium(III)-OMePT complex was formed in 3.4 mol L−1 aqueous hydrochloric acid media after 5.0 min heating in boiling water bath. The osmium(IV)-OMePT and ruthenium(III)-OMePT complex were measured at 518 and 640 nm against the reagent blank, respectively. Complexes were also extracted in 10 mL chloroform and showed comparable absorbance values. Beer’s law was obeyed up to 110.0 μg mL−1 for osmium(IV)-OMePT complex and up to 50.0 μg mL−1 for ruthenium(III)-OMePT complex. Molar absorptivity and Sandell’s sensitivity of osmium(IV)-OMePT and ruthenium(III)-OMePT complexes were 2.12 × 103 L mol−1 cm−1, 0.089 μg cm−2 and 2.34 × 103 L mol−1 cm−1, 0.043 μg cm−2, respectively. The stoichiometry of osmium(IV)-OMePT and ruthenium(III)-OMePT complex was 1:1 and 1:2, respectively. Stability of osmium(IV)-OMePT complex was > 8 days and that of ruthenium(III)-OMePT complex was > 48 h. The proposed method was successfully applied for determination of osmium(IV) and ruthenium(III) from synthetic mixtures corresponding to platinum-osmium alloy and fissium alloy, respectively. The method was successfully applied for sequential separation of osmium(IV), ruthenium(III), and platinum(IV). © , Copyright © Taylor & Francis Group, LLC.
