Dengue is the most prevalent mosquito-borne viral infection
worldwide. Over half of the world's population live in areas at
risk of dengue infection. The disease is transmitted principally by
Aedes spp. mosquitoes. Dengue Outbreaks were recorded in all
countries of the Indian Subcontinent with Pakistan, India,
Bangladesh and Sri Lanka resulting in huge number of cases and
deaths. It is a disease caused by four serotypes of a same virus
i.e. DENV1, DENV2, DENV3 and DENV4. In all major outbreaks, DENV2
and DENV3 were recorded as dominating and disastrous serotypes in
the region. Climate is a vital factor influencing DF outbreaks;
temperature, humidity, rainfall and flood play a fundamental role
in DF outbreaks, as providing optimum conditions for vector
population growth.Presently, prime prevention of dengue is possible
only with vector control and personal protection from the bites of
infected mosquitoes.
One hundred cases of various types of angina pectoris in two
hospitals of Narowal during September 2008 to January 2009 had been
analyzed to determine the relative occurrence and incidence of
angina pectoris, and effects of various risk factors. The analysis
shows that silent angina pectoris were more prevalent (79%,
n=79/100), and painful angina pectoris were less prevalent (21%,
n=21/100). About 56% cases reported, belong to the age class 41-60
years with a higher incidence of silent angina pectoris. Angina
pectoris is more prevalent in females (65.00%) as compared to males
(35.00%). In relation to various risk factors, silent angina
pectoris is the most prevalent. The mortality rate in this sample
due to angina pectoris is 12.00%.
Pakistan is in the race of economic development like other
developing countries, and has consumed a lot amount of energy to
run her economic cycle. Almost 54% out of total primary energy
consumption depends on oil and gas, which contributes more CO2
emission after coal in environment. Therefore, energy consumption
is the major cause of environmental pollution. The government of
Pakistan like that of other developing countries would never think
to mitigate the climate change at the expense of its economic
growth. This issue is more sensitive in nature that is going to
explore the relationship between climate change, energy consumption
and economic growth in case of Pakistan. The EKC curve hypothesis
which does not exist in case of Pakistan, tells us that the
pollutants are increasing with increasing trend but no yet turning
point exists. The government should have to put some efforts in
order to reduce and control the air pollution by identification and
evaluation of GHG emissions by area and their types of GHG
pollutants. The internal emission targets and devises strategies
should be met the Kyoto Protocol mitigation goals.
The design of bridges is a unique art as they are expected to carry
moving loads compared to the statically loaded structures. Mere
training in code procedures and special design skills are
inadequate for successful professional practice. Thorough
understanding of basic concepts and response characteristics of
various structural elements is necessary for professional bridge
designers. This book encompasses the manual and computer aided
design of prestressed concrete bridges. Besides explaining the
detailed design procedures for designing various components of
prestressed concrete girder bridge; this book also focuses on the
basic concepts and definitions of various bridge components. The
theory of prestressing with its merits and demerits is also
discussed in detail. The manual design procedure of different
members of prestressed concrete bridges is explained in a
comprehensive and step-by-step manner. Illustrations are used to
explain the computer aided design method. The design and analysis
results are compared in the end and discussions are made in order
to explain the reasons for possible discrepancies.
This book provides a compact knowledge about practical applications
of bioinformatic approaches to understand the structure and
function of a protein- Rhodesian which is found in visual pigment
of eye and responsible for controlling night vision. Its structure
has been predicted by comparative homology modelling and model
evaluation through various tools. The electron density maps of
retinal isomers and structure of rhodopsin intermediates were
analyzed by structure superimposition. On the basis of structural
analysis of thirteen mutations for Autosomal Dominant Retinitis
Pigmentosa, one of the missense mutation has been targeted to
propose a drug to cure night blindness. The molecular docking
technique has also been used to predict ligand interactions with
rhodopsin. It is hoped that this will provide new insights into
structural and functional exploration of proteins which will be
helpful in understanding various vital phenomena like protein
activation and inhibition, drug interactions and protein signaling.
Xylanases (endo-1, 4- -D-xylan xylanohydrolse; EC 3.2.1.8) is a
group of enzymes that catalyze the hydrolysis of xylan, the major
constituent of hemicellulose, which is second to cellulose in
abundance in plant cell wall. Xylanases are produced by a variety
of microorganism such as bacteria, fungi, actinomycetes and yeast
which are cultivated in solid and submerged fermentations. Fungi
are the most common sources of xylanases which can produce
thermophilic enzyme in fermentation process. Xylanases have
potential applications in various fields like bleaching agent in
the pulp and paper industry (brightening of the pulp to avoid the
chlorine free bleaching operations), hydrolyzed the xylan component
from wood which facilitate in removal of lignin, in baking
industries and in animal feed industry. This enzyme produced can be
utilized in saccharification for ethanol production. This study is
focused on optimization of cultural and nutritional parameters on
xylanase production by Trichoderma viride in solid state
fermentation using agricultural wastes as a substrate.
Cellulases are a group of enzymes which can effectively degrade the
cellulose, thus converting into glucose units which are further
fermented by Sacchromyces cervisae into ethanol. These cellulases
are produced by a variety of organisms like insects, bacteria and
fungi. Fungi are the most potent producers of cellulases in both
submerged and solid state fermentation processes. Generaly,
cllulase production from fungi is time taking process i.e. their
single batch is mostly completed in six to seven days of
fermentation period. To overcome this long time span an attempt was
made to produce cellulase from bacterial species. The present study
was carried out to isolate and identify the cellulose degrading
bacteria from soil samples.

Enzymes are biological catalysts which accelerate the chemical
reactions in living things without being consumed. A catalyst is a
material which builds a chemical reaction goes faster, without
itself being altered. A catalyst can be utilized again and again in
a chemical reaction: it is available again for same function.
Enzymes are exceptionally the same apart from that they are simply
denatured by heating. This book discussed about the history of
enzymes, Production criteria, biotechnology, classification,
Kinetics and Enzyme applications. Enzyme biotechnology involves the
utilization of microorganisms such as yeast, mold or bacteria, and
enzymes to make goods and services is a promising field in modern
biotechnology. I am looking forward to work in a professional and
competitive environment where It can put my best efforts, hard work
and skills to bring up the organization and myself too. I am also a
life long learner and am determined to become a knowledge
professional for keeping abreast with changing technology.
This book explores the interaction of Eugene O' Neill's characters
with their living space which includes their interaction with the
audience, the world outside that they envision through the opening
of a window or a door; and their interaction with every object that
is present on stage. This interaction does have a psychological and
metaphysical impact on the characters. Even the costumes they wear
and the books that they possess have a specific purpose. These
unleash the mood and the psychological outlook of the characters. A
mere change in costume often tells us about the change in
psychological outlook. The objective of this book is to explore
this psychological and metaphysical outlook of the characters in
selected plays of O' Neill. The first chapter gives a detailed
introduction of the research work. In second chapter, O'Neill's use
of dramatic space is explored. The third chapter focuses on
metaphysical interaction of characters with their space and the
fourth chapter entails psychological impact.
Self organization is a natural way of arranging the things. All the
forces in nature have a tendency to arrange the things in a well
patterned and ordered way. The devices fabricated by self
organization of nanoparticles show very interesting electrical and
optical characteristics which can be controlled by precisely
changing the structure of layer stacks and properties of the
materials used. In this book the multilayer devices fabricated by
layer-by-layer self assembly process using colloidal Au( 20nm) and
ZnS( 30nm) nanoparticles are discussed. A remarkable improvement in
the electrical and optical properties of deposited layers can be
brought by controlling the pH of the colloidal solutions and
deposited films using buffer solutions during the assembly process.
This book also covers the complex conduction phenomena in these
devices by discussing the similarities between the onset voltage
and current values of different sized array structures. The
experimental results in this book may act a guideline for engineers
and scientists in the field of Microelectronics for exploring
future fabrication techniques of electronic circuits and devices.
In this challenging economical era of Internet and Globalization,
the need for more and more data distribution to different users on
various types of networks in short time and at a nominal cost has
also been amplified drastically. The widespread growth of the World
Wide Web has made information easy to disseminate and distribute
over a network of computer networks i-e Internet. Content
Distribution Network (CDN) is a system of computers holding copies
of data, placed at different nodes in a network in order to
maximize bandwidth for access to the data from clients throughout
the network. A client accesses a copy of the data near to the
client, as opposed to all clients accessing the same central
server, so as to avoid bottleneck near that server. Content
Distribution Networks encompass so many benefits such as dynamic
routing and efficient distribution of content to reduce user delay.
CDN provides users their requested content from the fastest point
of presence no matter where in the world they are located.
