Liquid crystal the fourth state of matter is observed between the crystalline solid and amorphous liquid states. It exihibits the properties of liquids as well as that of crystalline solid state. In the present study we have considered an infinite static layer of cholesteric liquid crystal lying between two infinite hot co-axial circular cylinders in the presence o...

The present study is dedicated to analyze the flow, heat and mass transfer characteristics of nanofluid flow through different geometries under different conditions. The nanofluid flow through different solid objects, such as porous plate, parallel plate channel, bidirectional stretching surface, unidirectional stretching surface, etc., are commonly used in many fi...

Seed Industry in India: Poised for a leap Seeds form the fundamental and crucial input for sustained growth in farm production, often stimulating the use of new methods, machinery and yield-enhancing agro-inputs. The role of the seed sector is not only to ensure adequacy in seed quality but -. also to ensure varietal diversity. Today, India is one of the biggest Se...

A study has been conducted on the flow of an incompressible cholesteric liquid crystals with director of unit magnitude between two infinite relatively moving parallel hot plates with the objective: To examine the effects of uniform magnetic field in (x,y,z) directions in the plane of the lower plate which is at rest while the upper plate is motion with a uniform h...

To meet the need of growing population in India the g-rowjh in agriculture production has to be accelerated. For sustainable high crop yields, balanced fertilization with all the nutrients, which are deficient in soils, must be adopted without further delay. This is essential in view of continuous mining of soil nutrients -- over decades without adequate replenishr...

The thesis has been divided into five chapters. The first chapter is the introduction of the whole thesis. The second chapter is devoted to review of the literature in which we have tried to show the researches in group theory. In the third chapter namely, methodology, we have defined concepts which are necessary tools to make the thesis self contained. This is...
