The rhizosphere is a very complex environment in which the effects
of the plant on soil microorganisms and the effects of the
microorganisms on the plant are interacting and are interdependent.
Plant root exudates and breakdownproducts attract microbes and feed
them and, in turn, the plants often bene't from the microbes.
Interactions among microorg-
ismsandplantrootsareessentialfornutritionalrequirementsoftheplant.
Plant growth, development and productivity are largely dependent on
the soil environment in the root region rhizosphere. The new
techniques of studying the rhizosphere enables us to get a much
better understanding of the dynamics of the rhizosphere population,
such rhizosphere studies beingofinteresttoagriculturists,
soilbiologists, chemists, microbiologists andmolecularbiologists.

competitionandsynergisminsoilandtherhizoplane(r- zosphere) are the
most important microbial interactions to consider in the study of
rhizosphere biology. With the growing information on the production
of growth regulators, competitiveness of the microbes in the
rhizosphere, microsymbionts, and other factors, their effect upon
plant growth will become more evident. Experiments on the

The fundamental problem the world faces today, is the rapidly
increasing pressure of population on the limited resources of the
land. To meet the ever increasing demands of expanding populations,
agricultural production has been raised through the abundant use of
inorganic fertilizers, the adoption of multicropping systems and
liberal application of chemical pesticides (fungicides,
bactericides, etc. ). Though the use of chemicals has increased the
yield dramatically, it has also resulted in the rapid deterioration
of land and water resources apart from wastage of scarce resources.
This has adversely affected the biological balance and lead to the
presence of toxic residues in food, soil and water in addition to
imposing economic constraints on developing countries.' (From the
Preface) Mycorrhizal Biology addresses the global problem of land
degradation and the associated loss of soil productivity and
decline in soil quality caused by exploitative farming practices
and poor management in developing countries, and the far reaching
socio-economic and ecological consequences of its impact on
agricultural productivity and the environment. In the light of a
need for sustainable development, a new system of productive
agriculture, to ensure the efficient management of agricultural
inputs for long term high crop productivity with minimum damage to
the ecological and socio-economic environment is essential. The
management of mycorrhizal fungi will form a significant part of
such a system and this work investigates the key association of
plant roots with mycorrhizal fungi, known to benefit plants under
conditions of nutritional and water stress and pathogen challenge
and analyses thedevelopments in our understanding of the genetic
loci that govern mycorrhiza formation.
QUANTUM COMPUTING A helpful introduction to all aspects of quantum
computing Quantum computing is a field combining quantum
mechanicsâthe physical science of nature at the scale of atoms
and subatomic particlesâand information science. Where ordinary
computing uses bits, logical values whose position can either be 0
or 1, quantum computing is built around qubits, a fundamental unit
of quantum information which can exist in a superposition of both
states. As quantum computers are able to complete certain kinds of
functions more accurately and efficiently than computers built on
classical binary logic, quantum computing is an emerging frontier
which promises to revolutionize information science and its
applications. This book provides a concise, accessible introduction
to quantum computing. It begins by introducing the essentials of
quantum mechanics that information and computer scientists require,
before moving to detailed discussions of quantum computing in
theory and practice. As quantum computing becomes an ever-greater
part of the global information technology landscape, the knowledge
in Quantum Computing will position readers to join a vital and
highly marketable field of research and development. The bookâs
readers will also find: Detailed diagrams and illustrations
throughout A broadly applicable quantum algorithm that improves on
the best-known classical algorithms for a wide range of problems
In-depth discussion of essential topics including key distribution,
cluster state quantum computing, superconducting qubits, and more
Quantum Computing is perfect for advanced undergraduate and
graduate students in computer science, engineering, mathematics, or
the physical sciences, as well as for researchers and academics at
the intersection of these fields who want a concise reference.
Fungi playa major role in the sustainability of the biosphere, and
mycorrhizal fungi are essential for the growth of many of our woods
and forests. The applications of fungi in agriculture, industry and
biotechnology remain of paramount importance, as does their use as
a source of drugs and to help clean up our environment. This volume
contains key papers from the conference 'From Ethnomycology to
Fungal Biotechnology: Exploiting Fungi from Natural Resources for
Novel Products'. This was the first international scientific
conference covering the transfer of traditional remedies and
processes in ethnomycology to modern fungal biotechnology. The
conference was held at Simla, Himachal Pradesh, India from 15 to 16
December 1997. The key subject areas addressed in the conference
were the issues of exploring and exploiting fungal diversity for
novel leads to new antibiotics, enzymes, medicines and a range of
other leads for wood preservation, biological control, agricultural
biotechnology and the uses of fungi in the food industry. The
conference programme included key-note presentations followed by
poster sessions and general discussion. The book is broadly based,
covering five main areas: Ethnomycology, Fungal Biotechnology,
Biological Control, Mycorrhizal Fungi and Fungal Pests. There is no
doubt that in the past fungi have played a key role in
ethnomycological remedies and that in the future they will continue
to attract the interest of a wide range of disciplines ranging from
environmental conservation, agriculture and the food industry to
wood preservation and aerobiological studies.

In the 19th and 20th centuries, people commonly known simply as
Asians from the Indian subcontinent settled in East Africa (Kenya,
Tanzania, and Uganda) in ever-increasing numbers. By the turn of
the 20th century, Indian immigrants outnumbered Europeans in the
region by more than a 2:1 ratio. It signified the extraordinary
influence they wield over and the effect they have on the
socioeconomic, political, and cultural aspects of East African
society. Because existing literature on the subject is either
incomplete or cursory, an overall assessment of the large-scale
Asian immigration impact on East African development is woefully
inadequate. Therefore, in what is one of the most exhaustive
examinations of the phenomenon ever produced, this book came into
being under the expert research of Jagjit Singh Mangat. In light of
the dearth of written sources-with the few available being
drastically hard to find-Mangat uses interviews with surviving
immigrants to flesh out our knowledge and understanding. For
instance, he introduces us to traders who pioneered commercial
exploitation of the protectorate's interior during the 1880s and
1890s-a people and their endeavor little known outside local Asian
tradition until now. While subjective in nature, these interviews
nonetheless provide comprehensive insight into the life and work of
early Asian immigrants, from their own unique viewpoint. Using both
official and unofficial documentation from the India Records Office
in London, the Proceedings of the Emigration Department at the
India Office, and records of the former Bombay Presidency, to name
a few, A History of the Asians in East Africa, ca. 1886 to 1945, is
a definitive record of the extraordinary journey of Indian
immigrants and their powerful impact and influence on the
development of East Africa in the past and how that has shaped the
region today.
