Study of the Problems of Persons with Disability (PWD) Using FRMs

In this paper authors find the interrelations and the hidden pattern of the problems faced by the PWDs and their caretakers using Fuzzy Relational Maps (FRMs). Here they have taken the problems faced by the rural persons with disabilities in Melmalayanur and Kurinjipadi Blocks, Tamil Nadu, India

Super Fuzzy Matrices and Super Fuzzy Models for Social Scientists

This book introduces the concept of fuzzy super matrices and operations on them. This book will be highly useful to social scientists who wish to work with multi-expert models. Super fuzzy models using Fuzzy Cognitive Maps, Fuzzy Relational Maps, Bidirectional Associative Memories and Fuzzy Associative Memories are defined here. The authors introduce 13 multi-expert models using the notion of fuzzy supermatrices. These models are described with illustrative examples. This book has three chapters. In the first chaper, the basic concepts about super matrices and fuzzy super matrices are recalled. Chapter two introduces the notion of fuzzy super matrices adn their properties. The final chapter introduces many super fuzzy multi expert models.Comment: 280 page

Cation and anion transport through hydrophilic pores in lipid bilayers

To understand the origin of transmembrane potentials, formation of transient pores, and the movement of anions and cations across lipid membranes, we have performed systematic atomistic molecular dynamics simulations of palmitoyl-oleoyl-phosphatidylcholine (POPC) lipids. A double bilayer setup was employed and different transmembrane potentials were generated by varying the anion (Cl−)(Cl−) and cation (Na+)(Na+) concentrations in the two water compartments. A transmembrane potential of ∼ 350 mV∼350mV was thereby generated per bilayer for a unit charge imbalance. For transmembrane potential differences of up to ∼ 1.4 V∼1.4V, the bilayers were stable, over the time scale of the simulations (10–50 ns)(10–50ns). At larger imposed potential differences, one of the two bilayers breaks down through formation of a water pore, leading to both anion and cation translocations through the pore. The anions typically have a short residence time inside the pore, while the cations show a wider range of residence times depending on whether they bind to a lipid molecule or not. Over the time scale of the simulations, we do not observe the discharge of the entire potential difference, nor do we observe pore closing, although we observe that the size of the pore decreases as more ions translocate. We also observed a rare lipid flip-flop, in which a lipid molecule translocated from one bilayer leaflet to the opposite leaflet, assisted by the water pore.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87872/2/074901_1.pd

Floral Biology and Breeding System of Garcinia Imberti Bourd.-A Critically Endangered Tree Species of Western Ghats, Kerala, India

Plant flowering and breeding characteristics are important to understand the reproduction of plant populations. Garcinia imberti belongs to the family Clusiaceae is a critically endangered tree species of Agasthyamalai hills and endemic to Western Ghats, Kerala, India. Present study is to investigate the floral biology and breeding system during 2012-13. The tree species is dioecious. The peak of male and female flowering was observed in Feb-May, but the male flowers were observed one week before the female flower. Female flowers are significantly larger than the male flower. Both sexual morphs have four petals and four sepals in imbricated arrangement. Controlled pollination experiment showed that Garcinia imberti was a self-incompatible species that produced fruits through cross-pollination. According to the field observations after pollination treatments fruit setting was observed as 53.33%, 30.00%, and 36.67% in cross pollination, apomixis and open pollination respectively. This indicates a functionally dioecious mating system and pollination limited fruit set in Garcinia imberti. Female flower bear fruits with 1-2 seeds. Floral visitors observed in only in male flowers. These are not pollinators and they never observed on female flowers

Prospects of Grouper Culture in India

The "Groupers" of the genus Epinephelus are excellent marine food fishes in the Indo Pacific and Carribean regions and have assumed importance for commercial culture in recent year

Modelling of a thin film thermoelectric micro-Peltier module

A micro Peltier cooler/heater module has been modelled. The module consists of n-type bismuth telluride and p-type antimony telluride thermoelectric materials. The commercial software package CFD-ACE+ has been used to implement and analyse the model. A two-dimensional coupled electrical and thermal simulation was performed. This software includes the possibility to incorporate the Peltier effect. The temperature, electric field intensity and wall heat flux distributions were simulated for different applied potentials. The variation in temperature difference with respect to the Seebeck coefficient of the material was calculated and analysed
