This book provides an overview of eco-friendly resins and their
composite materials covering their synthesis, sources, structures
and properties for different industrial applications to support the
ongoing research and development in eco-friendly and renewable
commercial products. It provides comparative discussions on the
properties of eco-friendly resins with other polymer composites. It
is a useful reference on bio-based eco-friendly polymer resins,
wood-based composites, natural fibers and biomass materials for the
polymer scientists, engineers and material scientists.

The work demonstrates a techno-economic model of power generation
for the cost-effective integration of renewable energy sources,
with the goal of reducing greenhouse gas emissions in Canada. The
methodological approach outlined by the author is based on periodic
simulation of price variations. The result demonstrates that a 10%
transition to renewable energy generation is possible, practical
and affordable when supported by an effective policy framework that
does not need to introduce a feed-in tariff or loan-based financial
mode.
Waste management problem has raised a huge attention from many
authorities. Besides that, non-renewable energy depletion caused
awareness to the society on curbing the issue. Due to these current
issues, biogas production from solid waste was introduced. In this
work the method to produce the biogas was anaerobic digestion. It
is a digestion process of organic wastes without the presence of
oxygen. A lab scale anaerobic digester for batch mode was built.
Methane production from solid waste specifically food waste (green
waste, kitchen waste etc.) was done. The digestion process was done
by the aid of inoculum which was cow dung as the amount of
micro-organisms is high. A 350 liters plastic container of height
90 cm and diameter 70 cm was used as a bio-digester and biogas was
collected in tyre tubes. Methane tank was filled up to 70% of
volume by organic wastes. Methane production was monitored daily
and in detail on weekly basis. It was found that using a mixture of
cow dung and food waste retention period was 21 days. Gas started
to produce on 7th day. Amount of biogas obtained was 136 dm3. This
biogas digester may be used domestically as well as for the
demonstrative purposes.
A finger tip injury is one of the most common traumatic lesions of
the hand. Pain or dystrophy at the finger tip impairs the function
of the whole hand. Many of the distressing sequels of finger tip
injuries like painful scar, cold sensitivity, poor sensation etc
can be avoided by coverage with flaps. Often the injury is of such
nature, simple flaps like Klienert or Kutlar flaps are not suitable
and a resort to flaps from adjacent fingers may be required for a
good outcome. A useful and simple flap for such defect is the
dorsal cross finger flap. Sensation in the flap is imperative to
the proper functioning of the reconstructed finger tip. The study
to observe the way to return of two point tactile discrimination in
the flap after its division is a method of identifying adequate
functional re-innervations of the flap. The mean differences
between the 2PTD of final follow-up and the mean 2PTD of flap donor
site (expected to be recovered with time) was shown improving
gradually and significantly. So the sensory outcome in terms of
static 2-point tactile discrimination of cross finger flap was both
clinically and statistically satisfactory.
For successful fish culture the breeding of the fish is the most
vital aspect and can not be even thought without the knowledge of
breeding behavior of the fish, for that purpose the
Endocrinological observations have to be carried out. During the
last decade, fish endocrinology has observed stirring developments
due to advanced research at all levels of biological organization.
The book entitled as "CYCLIC ENDOCRINOLOGICAL CHANGES IN A
TEMPERATE FISH" will serve as a great scientific tool in the field
of fish endocrinology. The fish species of the tribe Oreinini of
the family Cyprinidae breed in running water only and their induced
breeding could not be carried out under controlled conditions in
confined waters. It is because of our meager knowledge about the
reproductive biology of these fishes. It is reported that their
population is continuously depleting in the water bodies of Kashmir
Valley which may be dangerous for their existence. It is expected
that this book will prove useful in breeding them in captivity and
thus protect them from extinction.
Control can be defined as keeping a physical variable (pressure,
temperature, level, flow etc.) as constant as possible by measuring
instantaneous value of physical variable, comparing it with the
desired value and using the difference to make a correction which
reduces this difference. It may include everything from a process
control computer and then the control components: the switches,
stepping motors, solenoids, and sensors. Programmable Logic
Controller (PLC) is used in Industries from last twenty yeas. This
is a very flexible controlling device, can be used in every type of
industries for the automation. An era was started after the
invention of microprocessor; to design develops
microprocessor-based system for automation of the machines. Similar
is in the case of PLC, when it was discovered in an automobile
industry. PLC which has a fixed hardware, manufactured by the
several manufacture worldwide, can be in-corporate in any
mechanical and electrical system by writing suitable programs, as
per the need of the user of machine or system. To fulfill this need
this control panel simulator will help the students to be a PLC
user.
