The living organisms and systems possess extraordinary properties of programmed development, differentiation, growth, response, movement, duplication of key molecules and in m any cases higher mental functions. But the organisms are physical objects so they must follow laws of physics yet they do not seem to obey them. Physicists cannot easily persuade themselves to accept this as finally true. Non-living objects are governed by these laws of physics and they can explain these properties. However, in the living systems too phenomena encountered like coupled non-linear interactions, manybody...

The thread of self-organization which is now recognized as permeating many dynamical transformations in diverse systems around us seems set to unleash a revolution as influential as that of Darwin in the last century. Darwin removed the 'originator' of a species; self-organization now seeks to remove the 'organizer' from an organism. Methods of nonlinear dynamics have played a crucial role in opening up this field and if these methods have a progenitor it is Henri Poi care (1854 - 1912) whose first substantial compilation amongst his prolific productio was Les Methodes Nouvelles de la...

Vegetables are important source of dietary fibers, minerals, antioxidants and vitamins. Shifting from a non-vegetarian diet to vegetarian, global recognition of the importance of vegetables for human health and their medicinal and nutritional value have contributed to a steady upward trend in vegetable production system. China is ranked first in the world and currently produces around 237 million tons of vegetable. The total vegetable production of India during the year 2009-10 was approximately 90 million tons. Pesticides are valuable tools in sustainable vegetable production, but...
