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.
