Abstract

Acidic and alkaline waste water similar to pumped mine drainage was treated with leaf litter over a classified substrate in a tank. Over 34 days the dissolved oxygen concentration increased from 5.6 to 7.3 mg/l in the case of alkaline water and from 4.2 to 6.8 mg/l in the case of acidic water. Other parameters such as hardness, Fe and Cl concentration, turbidity, redox potential and conductivity either showed improvement or remained constant. The water quality parameters were progressively shifted towards a state where higher rates of biological growth could be supported. The substrate soil also underwent a change for the better, acquiring a high organic content. It is concluded that the leaf litter provided food and shelter for the bacteria were responsible for the improved parameters., Acidic and alkaline waste water similar to pumped mine drainage was treated with leaf litter over a classified substrate in a tank.

291. A review on microelectrode array fabrication techniques and their applications

Author

Tanwar, A., Gandhi, H.A., Kushwaha, D., and Bhattacharya, J.

Abstract

Biosensors are an important tool for the detection and quantitative analysis of biomolecules and chemical compounds. There are a number of biosensors available based on the measurement of light, pH, electric current, pressure, etc. A microelectrode array (MEA) is one such biosensing device that detects changes in current, impedance, and potential. Due to its large number of applications in biosensing, electrophysiological studies of a cell, and drug screening, MEAs are widely used. In an MEA, sensing is achieved through microelectrodes, and based on the substrate used for MEA fabrication, MEAs can be rigid or flexible. Microelectrodes are developed by a process known as “microfabrication.” The process of microfabrication includes techniques like photolithography, screen printing, laser patterning, 3D printing, etc. This review discusses different MEAs and techniques used for their fabrication with recent applications.

295. On Analysis of the Periodicity Attributes of the Photo-Plethysmograph Signal to Assess the Cardiovascular State.

Author

Minai, Ali A., Bar-Yam, Yaneer, Kanjilal, P. P., Bandyopadhyay, S., and Bhattacharya, J.

Abstract

The photo-plethysmographic signal recorded from the finger, representing the blood pressure excursions, is studied. It is understood that any periodic or nearly periodic series can be considered to be composed of a series of cyclical segments where each segment is characterized by three attributes, namely the periodicity or period length, the periodic pattern and the multiplicative scaling factor. The dynamics of these periodicity (or p-) attributes for the plethysmograph signal are individually as well as collectively analysed to study the cardiovascular state. A new class of surrogate series based on the p-attributes is used for analysis. The signal dynamics is also analysed by mapping the p-attributes in a novel p-attribute space, where each point maps a periodic segment; from the distribution of points, a measure for the assessment of the cardiovascular condition is proposed.

296. Co-operation in the Brain in Higher Cognitive Functioning.

Author

Minai, Ali A., Bar-Yam, Yaneer, Bhattacharya, J., Petsche, H., and Pereda, E.

Abstract

We have analyzed the interdependencies between different regions of human brain during processing of different kinds of music by using multivariate EEG signals. In this study, a recent index, called similarity index, SI was used, which unlike the traditional linear measures is able to provide information about the direction of the interdependency. Relatively active and passive regions of the brain were highlighted, where the measure of the activity was reflected by the excited degrees of freedom at a typical length scale. The SIs during each task were compared statistically and significant changes (p ≤ 0.05) were depicted in schematic maps of the brain. A topographical representation of the S.I. showed differences in the connectivity while listening to different pieces of music. [ABSTRACT FROM AUTHOR]

297. In Search of Scaling in Brain.

Author

Minai, Ali A., Bar-Yam, Yaneer, Bhattacharya, J., Kanjilal, P. P., and Nizamie, S. H.

Abstract

A new approach based on orthogonal transformation and analytic signal analysis is utilized to characterize the hidden dynamical characteristics of EEG signal. Alpha band EEG signal is decomposed into relatively orderly (in terms of periodicity) and disorderly cyclical components using singular value decomposition based p-spectrum with moving windowed periodicity detection, followed by periodic decomposition. Normal, maniac and seizure subjects are studied. An analytic signal based approach is used for the characterization of the underlying functional structure of the brain. It is found that the normalized probability distributions of the amplitudes of the analytic signals for healthy brain show universal data collapsing phenomena (or homogeneous scaling behavior) which is a typical characteristic of physical systems at the critical point of phase transitions; for pathological subjects lack of universality (or heterogeneous scaling) is observed.
