Study of continuous dynamical system through Poincaré map is one of the most popular topics in nonlinear analysis. This is done by taking intersections of the orbit of flow by a hyper-plane parallel to one of the coordinate hyper-planes of co-dimension one. Naturally for a 3D-attractor, the Poincaré map gives rise to 2D points, which can describe the dynamics of the attractor properly. In a very special case, sometimes these 2D points are considered as their 1D-projections to obtain a 1D map. However, this is an artificial way of reducing the 2D map by dropping one of the variables. Sometimes it is found that the two coordinates of the points on the Poincaré section are functionally related. This also reduces the 2D Poincaré map to a 1D map. This reduction is natural, and not artificial as mentioned above. In the present study, this issue is being highlighted. In fact, we find out some examples, which show that even this natural reduction of the 2D Poincaré map is not always justified, because the resultant 1D map may fail to generate the original dynamics properly. This proves that to describe the dynamics of the 3D chaotic attractor, the minimum dimension of the Poincaré map must be two, in general. © 2013 Elsevier Inc. All rights reserved.

Total mercury levels were quantified in Tilapia mossambicus, Cirrhinus mrigela and Labio rohita, captured from East Calcutta Wetlands and Titagarh sewage fed aquaculture ponds. The bioconcentration factor of collected fish was assessed. Total mercury level ranged from 0.073 to 0.94 μg/g in both pre and post monsoon season. T. mossambicus in both season and C. mrigela at pre monsoon, cross the Indian recommended maximum limit (0.50 μg/g wet weight) for food consumption and according to World Health Organization guidelines all fish were not recommended for pregnant women and individuals under 15 years ages. A significant correlation was observed between mercury content of aquaculture pond water and fish muscle tissue. Total mercury concentration in experimental sites were higher than the control area (Wilcoxon Ranked-Sum test p > 0.05), which suggested the connection between mercury bioaccumulation and sewage fed aquaculture. © Springer Science+Business Media, LLC 2010.

Signal analysis is one of the finest scientific techniques in communication theory. Some quantitative and qualitative measures describe the pattern of a music signal, vary from one to another. Same musical recital, when played by different instrumentalists, generates different types of music patterns. The reason behind various patterns is the psycho-acoustic measures - Dynamics, Timber, Tonality and Rhythm, varies in each time. However, the psycho-acoustic study of the music signals does not reveal any idea about the similarity between the signals. For such cases, study of synchronization of long-term nonlinear dynamics may provide effective results. In this context, phase synchronization (PS) is one of the measures to show synchronization between two non-identical signals. In fact, it is very critical to investigate any other kind of synchronization for experimental condition, because those are completely non identical signals. Also, there exists equivalence between the phases and the distances of the diagonal line in Recurrence plot (RP) of the signals, which is quantifiable by the recurrence quantification measure τ-recurrence rate. This paper considers two nonlinear music signals based on same raga played by two eminent sitar instrumentalists as two non-identical sources. The psycho-acoustic study shows how the Dynamics, Timber, Tonality and Rhythm vary for the two music signals. Then, long term analysis in the form of phase space reconstruction is performed, which reveals the chaotic phase spaces for both the signals. From the RP of both the phase spaces, τ-recurrence rate is calculated. Finally by the correlation of normalized tau-recurrence rate of their 3D phase spaces and the PS of the two music signals has been established. The numerical results well support the analysis. © 2014 EDP Sciences and Springer.

For the purpose of phase space reconstruction from nonlinear time series, delay selection is one of the most vital criteria. This is normally done by using a general measure viz., mutual information (MI). However, in that case, the delay selection is limited to the estimation of a single delay using MI between two variables only. The corresponding reconstructed phase space is also not satisfactory. To overcome the situation, a high-dimensional estimator of the MI is used; it selects more than one delay between more than two variables. The quality of the reconstructed phase space is tested by shape distortion parameter (SD), it is found that even this multi-dimensional MI sometimes fails to produce a less distorted phase space. In this paper, an alternative nonlinear measure-cross auto-correlation (CAC) is introduced. A comparative study is made between the reconstructed phase spaces of a known three dimensional Neuro-dynamical model, Lorenz dynamical model and a three dimensional food-web model under MI for two and higher dimensions and also under cross auto-correlation separately. It is found that the least distorted phase space is obtained only under the notion of cross auto-correlation. © 2013 Elsevier B.V.

The present investigation reports the avifaunal diversity of Santragachi Jheel, which is a 12.75 ha wetland situated beside the Santragachi Railway Station (S.E. Rly), on the west bank of River Ganga, in the vicinity of Kolkata city. The period of investigation is between November 2009 and March 2010. The study site was found to be surrounded by dense human habitations, railway yards and small-scale industrial complexes. A total of 38 species of birds belonging to 23 families under 12 orders in which family Anatidae showed maximum density of 38 individuals. Order Passeriformes showed maximum family diversity of 10. Higher level of species diversity and richness reflects that further intensive studies are needed to make the complete checklist of the bird species of the Santragachi wetland as well as proper management of the area is essential for conservation of avifaunal diversity of the concerned study site.

Be it quotidian or haute cuisine, 'Caviar' or 'Quesadillas', cooking has always been a performance, in its experimentation to create an "appetite appeal" (Carafoli 146). This paper, through an analysis of Brad Bird and Jan Pinkava's directed, Disney animation Ratatouille, explores the engaging analogies and correlations between the processes in cooking and performance. The stage is being replaced by a single performative site - the kitchen, which becomes the theatre of action, producing the ultimate 'orgy of olfaction' (Kirshenblatt-Gimblett 7). A direct communication is shown to be reestablished between the spectator and the spectacle, between the actor and the spectator, from the fact that the spectator is invited to share the secret of the kitchen, and ultimately, is, not only affected by the sight, feel, taste, or smell of the final performative outcome - the food, but also impacted upon by the identity of the performer - Remy, the 'tiny chef' - nothing but a provincial rat. © Rupkatha Journal on Interdisciplinary Studies in Humanities.

One of the most popular methods to measure the quality of journal is impact factor. However this may not be the only criteria to evaluate a journal. It has its own limitations. The present work gives an alternative model to evaluate the quality of a journal. To test this model the present work used 17 popular journals on Social Sciences specifically in the areas of Economics, Political Science, and Sociology published in India during 2012–2014. The test proved to be successful. This model can be applied to any journal to find its quality. Three approaches have been considered, namely, physical presentation, reference studies and citation analysis. The model, named journal quality point (JQP), is suggested as a feasible technique to evaluate the quality of a journal. © 2016 Akadémiai Kiadó, Budapest, Hungary

Capillary rise, chloride and other salt penetration are the major causes of damage to the structure and are closely related to permeability in concrete and mortar. In fresh concrete, the space between the particles is completely filled up with water. The excess water in pores evaporates after the concrete hardens. The loss of moisture causes the volume of the paste to contract which in turn leads to shrinkage stress and shrinkage cracking. Moisture vapor transmission is also a function of relative humidity gradient between surfaces and permeability of concrete. These result in salt efflorescence, corrosion in metals, alkali aggregate reactions, sulphate attack through formation of gypsum and ettringite, freeze and thaw disintegration, erosion, carbonation, etc. They have a serious destructive effect on the structure as a whole. Heritage and old buildings which are devoid of damp proof courses and anti-termite treatments are highly permeable to all these natural damaging agents and need serious attention. This paper intends to discuss the action of an indigenous chemical when applied in fresh concrete and injected in mortars between brick layers for old and heritage houses. This chemical has been able to reduce the permeability to a substantial extent and many of the problems discussed above were, by and large, eliminated. © 2014 WIT Press.
