quantum mechanics in a coherent manner. The book is self-contained
and not only covers basic concepts in quantum mechanics but also
provides a basis for applications in atomic and laser physics,
nuclear and particle physics, and condensed matter physics. It also
covers relativistic quantum mechanics, in particular the Dirac
equation and its applications.
Stem cell based therapy is a 21st century approach of therapeutic
intervention which epitomizes a shift from conventional symptomatic
treatment strategy to addressing the root cause of the disease
process. This is especially a hope for the patients suffering from
diseases such as Alzheimer, diabetes, myocardial infarction and
other diseases which have always been considered as incurable.
Moreover, stem cells provide excellent in vitro disease models for
drug development. This book is a compilation of the bench
experience of experts from various research labs involved in the
cutting edge area of research, describing the use of stem cells
both as part of the combinatorial therapeutic intervention approach
and as tools (disease model) during drug development.

These proceedings cover the lectures delivered at the Third
International Summer College on Physics and Contemporary Needs held
from June 17 - July 5, 1978 at Nathiagali, one of the scenic hill
resorts in the northern part of Pakistan. The college was organized
by The Pakistan Atomic Energy Commission (PAEC) and co-sponsored by
the International Centre for Theoretical Physics, Trieste (ICTP).
It also received a financial grant by the University Grants
Commission for the participation of physicists from various
universities of Pakistan. The college was attended by 14 lecturers,
2 invited seminar speakers and 156 participants from 23 countries
and consisted of 15 concen trated days of lectures, seminars and
informal discussions. These proceedings contain only regular
lectures delivered there, but the seminars which were held there
are listed in the Appendix. This year the college put special
emphasis on energy, parti cularly on nuclear energy and its role in
the context of energy sys tems. However the lectures delivered at
the college also covered a wide spectrum of physics. The lectures
gave an overview of various topics covered at the college and
emphasized the inter-disciplinary aspects of physics. Some of the
lecturers also indicated the areas where research in developing
countries with limited facilities could be carried out. The college
had a definite objective of encouraging the physicists, part
cularly those working at the universities, to apply their knowledge
of physics and methodology of research to the needs of modern
society."
These proceedings cover the lectures delivered at the Fourth
International Summer College on Physics and Contemporary Needs held
from June 16 - July 4, 1979 at Nathiagali, one of the scenic hill
resorts in the northern part of Pakistan. The college was organised
by Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the
International Centre for Theoretical Physics, Trieste (ICTP),
Italy. It also received a financial grant from the University
Grants Commi ssion for the participation of physicists from various
universities of Pakistan. The college was attended by 16 lecturers
and invited seminar speakers. It was attended by 186 participants
from 28 coun tries and consisted of 15 concentrated days of
lectures, seminars and informal discussions. These proceedings
contain only regular lectures delivered at Nathiagali but the
seminars held there are listed in the Appendix. This year the
college put special emphasis on various energy systems, including
their long term implications, and computer software. However, the
lectures delivered at the college also covered a wide spectrum of
physics. The series of the colleges of which the present college is
the fourth one are an attempt to remove the barrier of isolation
for the physicists working in developing coun tries, far removed
from active centres of research. Thus these colleges could help to
fill the important gap in communication between the physicists of
developing and advanced countries."
Even in this age of information explosion, Seminars and Symposia
have an importance of their own, particularly in countries which
are scientifically and geographically remote from active centres of
learning. Our scientists suffer this isolation very acutely; the
Cow ission recognises this problem and has endeavoured to solve it
through organisation of meetings and conferences in Pakistan to
which international specialists in different fields are invited to
share their experience with colleagues in Pakistan. We find that
the personal encounter and human touch still remain one of the most
effective methods of transferring and sharing scientific knowledge.
The International Summer College at Nathiagali held in August,
1976, also grew out of our need to communicate with each other and
to identify promising areas of development relevant to the needs of
a developing country. In the implementation of this idea, the Pakis
tan Atomic Energy Commission received support from the
International Centre for Theoretical Physics, Trieste and from the
Swedish Inter national Development Authority which is gratefully
acknowledged."
These proceedings cover the lectures delivered at the Second
International Summer College on Physics and Contemporary Needs held
from June 20 - July 7, 1977 at Nathiagali, one of the scenic hill
resorts in the northern part of Pakistan. The college was organised
by the Pakistan Atomic Energy Commission (PAEC) and co-sponsored by
the International Centre for Theoretical Physics, Trieste (ICTP).
It also received a financial grant by the University Grants
Commission for the participation of physicists from various
universities of Pakistan. The college was attended by 13 lecturers,
7 invited semi nar speakers and 134 participants from 26 countries
and consisted of 15 concentrated days of lectures, seminars-and
informal discu ssions. These proceedings contain only regular
lectures delivered there but. the seminars which were held are
listed in the Appendix. The theme of the college covered two
important aspects of science in general and physics in particular:
first to provide to the participants from developing countries some
of the excitement of what is happening at the frontiers of physics;
secondly as the name of the college emphasises it was to encourage
the physicists from developing countries to interest themselves in
and to use their knowledge and methodology of research for
attacking some of the problems faced by their respective countries.
The lectures delivered at the college covered a wide spectrum of
physics and indicated similarity of methodology used in various
branches of physics as well as practical applications of some of
the topics discussed."
Arsenic was used more than 2400 years ago in Greek and Rome as a
therapeutic agent and as a poison. In current therapeutics use of
arsenic as a drug is limited. Recent studies indicate that people
of different countries are at higher risk of arsenic toxicity as
underground water in parts of the world is drained by deadly
arsenic. This book deals with the effect of arsenic on binding of
three common non-steroidal anti-inflammatory drugs; paracetamol,
aspirin and diclofenac sodium to bovine serum albumin. A detailed
literature review on arsenic contamination and health hazards
related to arsenic toxicity has been documented for reader's
convenience. Arsenic contamination in relation to Bangladesh was
also reviewed in details as Bangladesh is thought to be at greatest
risk of arsenic related negative health outcomes.
Mental retardation or intellectual disability affects about 3% of
the general population. One half of it is attributed to genetic
factors and is therefore inheritable. Genetic basis of mental
retardation is poorly understood. However information revealed from
the human genome project has enabled to analyze the genetic
determinants that have causative role in the onset of the disease.
This book provides a compendium of basic information on the genetic
factors that lead to this disability, methodology to screen the
causative genetic defects and identification of new causative
determinates. This information is critically important in the
diagnosis and prognosis of mental retardation at an early stage,
resulting in better management of the disease, ultimately leading
to improvement in life of the affected individuals. The book offers
a valuable source of information for the graduate and post graduate
students in genetics, biology and medicine.
The purpose of the present work was to design & evaluate
sustained release tablets of Nifedipine, employing hydrophilic
polymer to improve dissolution rates of the drug. METHOCEL K15MCR
& METHOCEL K100LVCR were used in tablets prepared by direct
compression. The formulated tablets were physicochemically
characterized & results were found in acceptable limits. Poor
aqueous solubility of Nifedipine leads to variable dissolution
rates. The main effect & interaction terms were quantitatively
evaluated using mathematical models. Dissolution data were fitted
to zero order, first order, Higuchi's, Korsmeyer-Peppas &
Hixson-Crowell release kinetics to evaluate kinetic data. The drug
release data fit well to the Higuchi expression, but a close
relationship was also noted with zero order kinetics. Korsmeyer's
plot indicated that the drug release mechanism from the matrix
tablet was to be found Fickian mechanism. Regulated drug release
study indicate that the matrix tablets of Nifedipine prepared using
above polymers can successfully be employed as twice-a-day oral
controlled release dosage form.
Bacillus thuringiensis cry proteins are effective in controlling
harmful insects. However, the mechanism of Bt protein pesticidal
action is not well understood. It is assumed that the pesticidal
protein has affinity for specific receptors in the midgut of the
susceptible larvae and binds irreversibly to create holes in the
gut leading to eventual death of the target larvae. Main aim of the
research is to identify, purify and characterize Bt delta endotoxin
receptor in important pest American bollworm (Helicoverpa
armigera). The study presented in this thesis is endeavored to; (1)
discovery of a receptor protein, (2) purification of the receptor,
(3)cloning of the newly discovered protein gene in E.coli, (4)
expression studies on recombinant protein, (5) Complete sequencing
of the cloned gene. The structural gene was cloned in expression
vector. The cloned gene was sequenced and studied expression. The
cloned, expressed, purified receptor protein was found to have
characteristics of native protein of H.armigera. A new method for
quick detection of Bt-receptor in crude BBMVs extract, was
established.The sequence has novelty and Accession # A59445)or
Q7M4K6.
Redevelopment of Bhairab River Bank: Focusing CBD Jessore,
Bangladesh by Riazuddin Kawsar and Architect Md. Arafat Hasan, is a
volume provides an urban planner's viewpoint on redevelopment of
river bank situated in a very old CBD of Jessore. Jessore is a
small but very old city, situated south zone of Bangladesh, which
