The world needs for food and fiber continue to increase. Population growth in the developing countries peaked at 2. 4% a year in 1965 and has fallen to about 2. 1%. However, in many developing countries almost half the people are under 15 years of age, poised to enter their productive and reproductive years. The challenges to produce enough food for this growing population will remain great Even more challenging is growing the food in the areas of greatest need. Presently the world has great surpluses of food and fiber in some areas while there are devastating deficiencies in other areas. Economic conditions and the lack of suitable infrastructure for distribution all too often limit the alleviation of hunger even when there are adequate supplies, sometimes even within the country itself. World hunger can be solved in the long run only by increasing crop production in the areas where the population is growing most rapidly. This will require increased efforts of both the developed and developing countries. Much of the technology that is so successful for crop production in the developed countries cannot be utilized directly in the developing countries. Many of the principles, however, can and must be adapted to the conditions, both physical and economic, of the developing countries.

In the present study, an attempt has been made to delineate alteration in cerebellar hemisphere of albino rats following nicotine exposure. From the above findings the following conclusions were drawn: There was no change in weight of cerebellum following long term exposure of nicotine. The thickness of the molecular layer was decreased significantly in experimental group rats. The thickness of the granular layer was decreased significantly in the experimental group rats. There was marked histopathological changes like glioma in the molecular layer of the experimental group rats. There was significant loss of the Purkinje cells following nicotine. The shape of the Purkinje cells was grossly altered. The vertical diameter of the Purkinje cells had decremental trend significantly following nicotine. Although the transverse diameter of the Purkinje cells did not follow a particular trend, it was changed significantly. The morphology of the white core of the cerebellum had extensive changes such as vacuolation, capillary dilatation, oedema."

In the literature of Operations Research, non-linear programming plays an important role in solving difficult optimization problems concerning the industry. The present book highlights the developments concerned with the theory of non-linear programming and its applications to various business oriented disciplines. It aims at addressing the key issues pertaining to these topics and will be helpful to Computer Programmers, Statisticians and Operational Researchers.

The present book highlights developments of new measures of fuzzy information and finds their applications for the study of maximum entropy principle and the development of new codeword lengths. The main objective of the book is to provide the knowledge of non-probabilistic measures and will be helpful in disseminating knowledge to the benefit of Information Theoreticians, Statisticians, Computer Scientists and Operational Researchers. The book presents new findings which will add to the knowledge of the scientific community for their future research.
