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.

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.

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.

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.
