A computer network, is a collection of computers and devices
interconnected by communications channels that facilitate
communications and allows sharing of resources and information
among interconnected devices. In other words, a computer network is
a collection of two or more computers which are linked together for
the purposes of sharing information, resources, among other
things.As today, all the media in the world are standing on data
communication and computer networking, it is always important to
understand the basics of networking. In the present book, the
different types of network topology, details of baseband and
broadband are described. There is a precise overview on data and
signal bits. The book also described the modulation and
multiplexing in computer networking. Different type of data
transmission and details of ethernet and TCP/IP are also described
in this book.
Community and diversity of waterfowls in Santragachhi Wetland have
been studied in four months during the winter period of 2008-2009,
which is the season for migratory water birds. The diversity has
been studied with respect to cumulative species richness and
relative abundance, Shanon-Weiner diversity, bootstrap richness,
Chao 1 richness, Coleman rarefaction richness. Attempts were also
made to find a correlation with these parameters to the photoperiod
of the day. Some of the potential threats of the wetland as well as
the inhabitants have also been noted. In this current project the
status and distribution of waterfowls in Santragacchi wetland were
recorded and their description were described.
Gurjar is a member of a South Asian, ethnic group mainly located in
eastern Pakistan, Kashmir, Gujarat, and northwestern India. Gurjars
traditionally belonged to the Kshatriya, caste, and formerly ruled
the Gurjara-Pratihara, Kingdom, which included much of northern
India during the 8th and 9th centuries. However, they are mostly
Muslims, a few being either Hindus or Sikhs. Conventionally they
have been cattle breeders and milkmen. They were usually associated
with herdsmen and shepherds and were a pastoral people. A large
number of Gurjars have now settled down and taken farming and
combine agricultural work with animal husbandry. In India, Gurjars
are categorized as 'other backward classes'. In India, Gurjar
populations are found mainly in Gujarat, Delhi, Jammu and Kashmir,
Himachal Pradesh, Punjab, western Uttar Pradesh, Uttarakhand,
Haryana, northern Madhya Pradesh, Rajasthan and Maharashtra. The
present study portrayed the historical aspects and socio-economic
development of Gurjar Community in India. the study also described
the livelihood of some villages of Rajasthan state in India.
Being a primary producers plants have always outnumbered faunal
elements. Botanist agree that presently there are about 2,45,000 (A
recent literature search reveiled that there are ca. 3,52,000
species (belonging to 406 families) of angiosperms of which
2,73,174 are accepted species names (The Plant List 2010)) species
of flowering plants on earth and these have been grouped in to 430
families, depending on the authority concerned. However, a basic
knowledge of angiosperms can be acquired by a study of a selected
group of families.I decided to study family Acanthaceae. The reason
for the selection of this family for project is the availability of
several representatives in and around Mumbai. The fascinating task
compelled me to take up the project. Acanthaceae includes 250
genera and 2500 species distributed all over the world (According
to recent literature at Tthe Plant List 2010, 2894 accepted species
names belonging to 225 genera) . Over 70 genera and over 340
species have so far been reported from India. In Maharashtra 54
genera and 202 species have been reported.

Photography is a part of art in which the artists makes a
photograph of a thought or idea. Usually the vision of the idea
precedes the realization of the photography. Photography is both an
art and a science. Photography allows us to express our feeling and
emotions, but to do so we need to be the master of the scientific
part of the medium. So there is always a need for the photographer
to know all the intricacies and thoughts behind photography. Our
book refers to the use of science, such as chemistry and physics,
in all aspects of photography. This applies to the camera, its
lenses, physical operation of the camera and electronic camera
internals in order to take pictures properly. This book also
focuses on detailed explanation of photographic factors, like
exposure, aperture area, exposure time, luminance and shutter
speed. One photographer should know the evolution of photography
with time and development. In this book, we explained the vision,
thoughts and the scientific use photographic parameters behind a
successful and satisfactory photograph.
National Tiger conservation Authority under MOEF, Government of
India, in its guideline has emphasized the concept of core - buffer
zonation in every Tiger reserve. The 2006 amendment in wildlife
(protection) act 1972, for the first time, has defined "core" and
"buffer" areas of a tiger reserve, the former being the critical or
inviolate area and later, the peripheral area to foster co
existence with local people for safeguarding the integrity of the
core. Since Buffer Zone is supposed to be a human dominated
landscape, its very much important to have a strong management plan
for conservation of wildlife and forest in these areas. the present
work established a case study for the management and conservation
of Buffer Zone of Sariska Tiger Reserve in Western India. The
intricacies, management aims and goals, SWOT analysis and future
planning of a the Buffer Zone of Sariska TR has been portrayed in
the present work.
Leopard (Panthera pardus) management in India is facing many
challenges. Leopards have highly diversified diets and are
extremely adaptable to various ecological conditions. This
versatility allows them to thrive in a broad range of habitats,
often bordering human settlements. In recent years the presence of
leopards has been increasing in a wide range of rural and even
built-up environments, far removed from natural habitats and
protected areas. Although leopards have shown a remarkable ability
to live relatively peacefully close to people, conflicts can and do
occur, with leopards killing livestock and in extreme cases people.
Due to fear and anger, many affected persons retaliate by injuring
and killing leopards. Because Indian law prohibits the killing of
schedule 1 species, responses have been confined to removing the
animal to captivity or translocating it to a new area. A thorough
review of strategy is therefore addressed in the present work to
address every possible human-leopard conflict situation and develop
appropriate protocols for response.
In India, sacred groves are scattered all over the country and do
not enjoy protection via federal legislation. Some NGOs work with
local villagers to protect such groves. Each grove is associated
with a presiding deity and the grove are referred to by different
names in different parts of India. They were maintained by local
communities with hunting and logging strictly prohibited within
these patches. While most of these sacred deities are associated
with local Hindu gods, sacred groves of Islamic and Buddhist
origins are also known. Sacred groves occur in a variety of places
- from scrub forests in the Thar Desert of Rajasthan. The present
study highlights the importance sacred grove in Indian
Civilization. A focus was given to Sariska Tiger Reserve, Rajasthan
to study the effectiveness of sacred grove. It was seen that, the
forest outside sacred grove in Sariska is being degraded year after
year, but the forest inside sacred grove shows high density.
Vegetation cover and disturbance parameters were also studied to
see the extent of effectiveness of scared grove for the
conservation of Sariska Tiger Reserve.
