Treatment of Mountains in Indian English Poetry

Literature is not only a mirror of (human) life but also of nature. Nature is one of the important aspects of this world. Without nature, human life or animal life is impossible. That much relevance nature has in this world. To some it is nothing; to some it is some objects; for some it is supreme like God. Wordsworth’s pantheism is well known. He could see God in various forms of nature. All people are not like him. C.N. Annadurai, one of the leaders of Tamil country said he could see God in the laughter of poor people. Nature includes its various forms like mountains, hills, rivers, ponds, seas, canals, waterways, fruits, flowers, trees etc. Many poets both Indian and foreign have sung of these as their themes in their poetry. Mountain is also taken for treatment in poetry, drama, novel and short story. Mountains not only guard a country like India where, on the northern side, the Himalayas is like a wall giving protection to the people of India. They are the birth place for many a river. Indian poets have taken mountains / hills also for treatment in their poems. The present paper analyses some poets’ treatment of mountains in their writings

A Study of the Portrayal of Animals in the selected Indian Writing in English Poems

Animals are the part and parcel of human life so in literature. Indian authors in most of the languages have represented different kinds of animals sometimes in negative and other time in positive ways. In literature it has been seen that most of the genres have represented animals in different forms. Various names of studies are prevalent related to animal studies. Anthropocentrism studies human beings as the center of the whole universe. It deciphers the importance of other creators in the universe. Ecocentrism studies nature and environment as the key to life on the Earth. Animals like, cow, horse, buffalo, tigers, bird, dog, cat, elephant, pig, bull, dear sheep, calf and many more have been represented since the emergence of literary practices. This paper aims to provide a brief note on how animals have been represented in the poetic expressions

Technology of processing mussel meat

Green mussel (Perna viridis) and brown mussel (P.indica) are available in substantial quantities from their natural beds along the south- east and south-west coasts of India respectively. Mussel is locally collected for its meat which is consumed in the nearby areas. Mussel meat normally finds favour with people of low income group and that too when the fish is scarce or costly, which often results in poor economic returns to the collector

Controllability of nonlocal impulsive stochastic quasilinear integrodifferential systems

Sufficient conditions for controllability of nonlocal impulsive stochastic quasilinear integrodifferential systems in Hilbert spaces are established. The results are obtained by using evolution operator, semigroup theory and fixed point technique. As an application, an example is provided to illustrate the obtained result

Existence of solutions of abstract fractional impulsive semilinear evolution equations

In this paper we prove the existence of solutions of fractional impulsive semilinear evolution equations in Banach spaces. A nonlocal Cauchy problem is discussed for the evolution equations. The results are obtained using fractional calculus and fixed point theorems. An example is provided to illustrate the theory

Controllability of Sobolev-type semilinear integrodifferential systems in Banach spaces

AbstractSufficient conditions for controllability of Sobolev-type semilinear integrodifferential systems in a Banach space are established. The results are obtained by using the Schaefer fixed-point theorem

Null controllability of nonlinear infinite delay systems with distributed delays in control

AbstractSufficient conditions for the null controllability of nonlinear infinite delay systems with distributed delays in the control are developed. Namely, if the uncontrolled system is uniformly asymptotically stable and if the linear control system is proper, then conditions are obtained that imply the nonlinear infinite delay system is null controllable
